With the help of their dog and Mary's sister, her life would never be the same, at least not sexually. (FF/beast, inc, reluc) *** Mary is a 36-year-old, divorced, mother of two boys. Between raising her two boys, completely alone, and working full time, Mary has no time for herself, let alone a man. For years she had promised her boys that once they were old enough to take care of it, she would buy them a dog. Now that her boys were thirteen and seven, she had no choice but to keep her promise. One evening, after she had gotten home from work and the boys had finished their homework, she took them to the pound and let them pick out a dog. They had both decided on a large, male, golden retriever, about nine months old. The boys named the dog Buddy. Buddy is really a sweet and loving dog. The boys could not wait to get home from school and play with Buddy. Buddy was really nothing more than an over grown puppy, that thought he was a lap dog, all 120 pounds of him. The boys loved to have Buddy jump on them and wrestle with them. The only problem with that was, when a stranger came over, Buddy would jump up on them, and sometimes knock them over. That was a habit Mary was going to have to teach Buddy to break. The last thing she could afford was a lawsuit from some neighbor trying to get rich quick. But, being so busy, Mary just never had enough time to properly train a dog. As the months went on, Buddy was starting to grow out of that puppy stage and began acting more and more like an adult dog and getting more adult dog urges. Now, instead of jumping on some just to play with them, he would jump on someone and start rubbing on them, trying to get himself off. Mary thought that was even worse and embarrassing, not to mention having to try to explain to her seven-year-old what he was trying to do. But still, Mary did not have a second of free time to herself, let alone time to train a stupid dog. Finally, after what seemed like decades, Mary had gotten some time to herself. Her parents decided to take the boys to their hunting cabin for the weekend and by pure luck, her boss had given her the weekend off. She thought she had died and gone to heaven. It was Friday evening and she had just walked in the door from work. The boys were already gone, but still there was Buddy, jumping on her and greeting her hello. Mary decided she was going to feed the dog, to get him out of the way, pour herself a glass of wine, and take a long, hot, bath. Mary could not remember the last time she was able to take a bath, let alone have more than ten seconds of peace and quiet. As Mary undressed and slipped into the warm bath, it seemed as if all of her cares just faded away. Mary was really beginning to relax and unwind. As she lay in the tub, she began to caress her small, but shapely body. She began by lightly caressing her breasts. Her breasts were not all that big, just barely a "C" cup. Instantly her nipples were hard as diamonds and standing out almost an inch. Slowly she moved one of her hands down to her pussy and began to slowly rub her outer lips, just occasionally brushing her clit. Slowly she began to insert a finger and then another. Slowly she began to move her fingers in and out of her slit, while using her thumb to rub her clit, while her other hand was still caressing her tits. She began to pick up the pace, slowly building herself up for the first orgasm she has had in months. Just as Mary was about to hit her peak, she was jolted back into reality by the ringing of the telephone. Her first instinct was to let the answering machine get it. After all, it was probably just one of those stupid sales calls. But then she thought, 'What if something happened to one of the boys?'. Mary jumped out of the tub, grabbed a towel and ran for the phone. It was indeed one of her boys, but they just wanted to tell her they made it to the cabin safely and they were having fun. Mary was glad and mad at the same time. Of course she was happy her boys were safe and having a good time, but she was so close to an orgasm she wanted to scream. This is sad she thought, I can not even masturbate without getting interrupted. If I do not get some time to myself and get laid soon, I am going to go crazy. Mary decided to carry on with her evening, but by the time she had gotten back to her bath, the water was already getting cold. Mary, still wet from her bath, with a towel still wrapped around her, decided to pour another glass of wine, go get on something comfortable and just relax. As she was walking down the tiled hall toward her bedroom, she slipped in a puddle of water, left there from her sprint to the phone. When she slipped, she spilled her glass of wine. Not wanting the wine to stain her white tiled floor, she quickly took the towel she was wearing and got down on all fours to wipe up the mess she had just made. Being the nosey dog he was, Buddy quickly ran over to see what all of the commotion was about. Buddy began to lick at the wine, but Mary quickly push him aside and got in front of him to keep him from drinking the wine, plus to get him out of her way, while she finished cleaning up her mess. With Mary still being a little wet from her bath, Buddy began to lick at her, instead of the wine on the floor. Mary did not think much of it. As Buddy continued to lick up her leg, he noticed a scent that was new to him and aroused him. Not only was Mary still wet from the bath, but her pussy was still wet from her almost orgasm. Buddy began to sniff closer to Mary’s pussy, but Mary was too busy cleaning up the mess to notice, that is until Buddy gave her pussy a big, wet lick. Mary screamed and jumped. It felt good for a split second, until she realized it was Buddy. Then she was repulsed. Buddy licked her pussy again, this time from her clit to her asshole. Again Mary screamed and pushed Buddy away. Buddy was now really getting excited. Little did Mary know, but Buddy’s dick was starting to show through his sheath. Just as Mary was trying to get up off of her hands and knees, Buddy jumped on her naked body, knocking her off balance and forward. From there, his adult doggie instinct took over. All of a sudden, Mary had a 135-pound dog on her back and something hard pocking at her ass. At first Mary thought Buddy just wanted to play, like he does when the boys are home, and she yelled at him to get down. She knew what a loving and gentle dog Buddy was, and she did not think Buddy would do anything to hurt her. A few more pokes in the ass made her realize what Buddy had in mind. Now Mary was scared. She realized that Buddy’s gentleness and sweetness were out the window and instinct was taking over Buddy. Mary tried her best to move and crawl out from under Buddy, but he was too big and strong. By now, Buddy had his paws wrapped around her waist, digging his paws into her skin, and she was not going anywhere. She knew it was just a matter of time before he found his target. Mary was about to be raped, by her own dog. Buddy continued to hump at Mary’s ass and Mary continued to try to escape, but she was too late. Finally, Buddy hit his target. Mary screamed yet again as Buddy began to penetrate her pussy. It had been so long since Mary had been with a man, that her pussy was almost virgin tight. Mary groaned as Buddy continued to sink his large dick deeper and deeper into Mary’s pussy. Due to Mary’s lack of sex and the huge size of Buddy’s dick, Mary felt like someone was trying to drive a truck into her pussy. After a few more hard thrusts, Buddy had managed to bury his entire cock into Mary’s pussy. Even at the peak of her sexual hay days, Mary had never had anything so large in her pussy. Mary thought her pussy was being ripped open from her ass to her stomach. After a few more minutes, Mary was starting to get used to his size and girth, and it was actually starting to feel good. Once again she could feel her orgasm start to build. Mary felt torn and betrayed by her body. She was humiliated and sickened about getting raped by a dog, but at the same time, she was finally beginning to enjoy her first sexual encounter in well over a year. Mary’s lust was beginning to overwhelm her feeling of shame, when all of a sudden she felt something bigger pushing against her pussy as Buddy continue to fuck her like a jackhammer. Mary knew nothing about a dog’s anatomy or sexual habits. Suddenly Mary gasped as she felt whatever that lump was, trying to penetrate her pussy’s lips. All of a sudden Mary felt like she was giving birth, as Buddy’s knot began slipping into Mary’s tight pussy. Mary again screamed in agony. Her head started swimming in pain and blackness. The shock and terror of being raped by her dog was starting to return, not to mention the fact of not knowing what was being shoved into her cunt. Finally, after a few minutes of Buddy banging his knot against her lips, it was finally buried inside her pussy. After the shock began to wear off, Mary once again started getting used to the fullness and again, was starting to let herself enjoy the fact that she was getting laid, even if it was with a dog. Mary also noticed that Buddy’s fast long strokes had slowed down some and he was not pulling out very as far. Then, she started to feel something hot and wet being shot into the depths of her womb. Buddy was cumming. After about ten minutes of shear pain, another few minutes of being stretched beyond belief, and yet another few minutes of getting used to the fullness, she felt as if someone had turned on a hot fire hose inside her pussy, as Buddy continued to cum and cum. She felt as if Buddy had deposited a gallon of cum inside of her pussy, yet through all of the terror, pain, and finally acceptance, Mary still had not been able to reach her much desired, orgasm. Finally, Buddy had finished cumming and began to turn around. Well, Mary thought, at least this is over with, or at least she thought it was. She tried to get up and free herself from Buddy, but she could not. She pushed and pulled, to no avail. Now she and Buddy were stuck together, ass to ass, with that huge dick still inside of her pussy. Now Mary was starting to worry. How long would she be stuck like this? What if somebody came over and saw her like this? Mary continued to struggle, but could not free herself from Buddy’s knot. Finally, after another thirty minutes, Buddy’s knot had shrunk enough to slip out of Mary’s pussy. When Mary finally broke free of Buddy, she heard a loud plop and cum poured from her aching pussy. Mary managed to crawl a few feet away before collapsing onto the floor in complete exhaustion and humiliation. Mary fell asleep, right there on the floor. Early the next morning Mary awoke, still naked and laying on the floor. At first she thought it must have been a dream. She looked around and did not see Buddy. Nor did she find any mess on the floor from, where she had spilled her wine, or from all of the doggie cum, that had drained from her pussy. But when she went to stand up, she quickly realized it was no dream, as her pussy was still very sore. Mary had spent most of Saturday morning just lying around the house, trying to comprehend what exactly had happened to her the night before. She was very confused, humiliated, and unsure about the whole experience. Again she decided to take a warm bath and to try to forget about what had happened. But just as the night before, Mary had begun caressing herself and made herself even hornier than before. She continued going over and over the events of the night before in her mind, before she finally masturbated to a small, unimpressive, orgasm. Bored with the bathtub and still unsure about the events of the night before, Mary decided to get out of the tub. She was now hornier than she had ever been in her life. She was also very curious about what had happened to her, about how dogs have sex, and about why she was stuck together with Buddy for so long. Mary decided to go online to see what she could find out about dogs and their sexual habits. Mary spent several hours online, reading about dogs, their knots, and mating rituals. Then she came across a web site full of stories about women who have sex with their dogs and how much they love it. Needless to say, this made Mary even more horny. Mary continued to read the stories about woman that fuck their dogs, rubbing her pussy, through her panties, as she read. Mary stopped when she realized her panties were completely soaked with her juices and decided she wanted to try it again, only this time under her terms. Mary put down a thick and comfortable blanket on the floor, laid down on it, and called Buddy over to it. As usual, Buddy came running over and jumped on her, thinking she wanted to play and wrestle. After a few minutes, Mary was able to get Buddy to settle down and lie down on the blanket beside her. Mary rolled Buddy on to his side and began to lightly touch his sheath. At first Buddy jumped and pulled away, but eventually, Mary was able to again, calm him down and let her explore. This time she wanted to be able to see and control the situation. The first thing she wanted to know was how big his dick actually was. Mary began the caress his sheath unit his red dick started to come out. Mary was very surprised by the red color of his dick and it’s texture. She continued to play with his dick and also started playing with his balls in an attempt to get him fully erect. It seemed like the more she played, the bigger it got. She could not believe how big it was getting and that she was able to fit that entire thing, plus his knot, into her small, tight pussy. Another thing that surprised her was how slimy it felt. Before she knew it, Mary was actually giving Buddy a hand job. She stopped when she realized how wet she was getting. Mary’s panties were starting to drip with her wetness. Mary decided it was time to take off her clothes. As soon as she did, Buddy managed to get a hold of her underwear and start licking away at the crotch. Mary continued stroking Buddy as she was trying to build up the courage to suck on his cock. Mary had given a blowjob a few times before, but she was not crazy about them. But this seemed different. This time she really wanted to, in a weird sort of way. Buddy continues to lick at Mary’s panties as she was still trying to drum up the courage to suck on Buddy’s cock. Mary decided that would have to wait, as she was getting to horny. She moved around to get in front of Buddy, pulled her underwear away from him saying, if you liked those, you will love licking the real thing. Mary inched closer to Buddy’s snout and spread her legs. Buddy instantly recognized the scent and began licking at her cunt. Chills ran down Mary’s spine as Buddy began licking away at her outer walls. Eventually he worked his way to her clit and then started penetrating her tight lips. Mary leaned back and enjoyed the ecstasy. Within minutes, Buddy had brought Mary to an earth shattering orgasm, stronger than any orgasm she had ever had. After about fifteen minutes of Buddy licking every inch of her cunt, inside and out, about a thousand times, and Mary’s multiple orgasms, she finally had to pull away and make him stop. The multiple, mind-blowing orgasms, were making Mary light headed, and she thought she was about to pass out. It was time for a short break, at least on the receiving end. Mary crawled back down to Buddy’s hindquarters and again starting playing with his semi erect cock. She slowly stroked it back and forth and was amazed at how much it was growing. By this time, his cock was about nine inches long, and as thick as a silver, half- dollar. By now Mary’s lust was driving her more and more. She decided she wanted to see what his dick would taste like. At first, she rubbed her finger up and down his shaft and then licked her fingers to see what it would taste like. Her first impression was that it had a salty, yet bitter hint to it, but she could not be sure by just sucking her own finger. Next, she put her face to his cock and began to take a few small, fast licks. Again she tasted a salty, bitter taste, but nothing that would repulse her. Finally, she got up the nerve to put his cock in her mouth. At first Mary was not sure what she should do. Should she just lick at it, or suck it like a man’s cock. Eventually instinct took over and she was give Buddy his first blowjob. Now Buddy was starting to get excited and his cock was continuing to grow. Of course Buddy’s natural instinct was for him to start humping. Before Mary could realize what was happening, Buddy had jammed his now, fourteen-inch cock, down Mary’s throat. Mary began to choke and gag before she was finally able to pull back enough so she could breath, as well as not to swallow his entire cock. Mary continued sucking Buddy’s cock for a few more minutes, until she started to feel his precum starting to shoot out of his cock. Mary was note sure if she was ready to let a dog cum in her mouth. After all, she would never let her ex-husband do it, on the rare times she gave him a blowjob. Mary decide this was a good time to stop, as she was get horny again and did not want Buddy to blow his load before she had a chance to fuck him, only this time it would be her way, or so she thought. When Mary pulled back, she was shocked the see the size of Buddy’s cock. It was at least fourteen inches long and as thick as her wrist. She also noticed Buddy’s knot starting to expand. It was almost the size of a tennis ball. Little did she know, it was still growing. She had not seen Buddy’s full size the night before, and was in awe to think that all of that was stuffed inside of her pussy, only hours before. Mary was now starting to have second thoughts about the whole thing. But the more she played with Buddy’s cock and balls, the hornier she got. She eventually rationalized that if she could survive the rapping she took last night, she could handle it again, seeing as how she thought she was going to be able to control everything this time. Again Mary moved herself in front of Buddy, so he could lick out her pussy, while she tried to loosen it up a little. About two minutes of this was all she could stand. She wanted a cock in her pussy and she wanted it now. Again, not knowing much about fucking dogs, she thought the only way she could get fucked was doggie style. But this time, she was going to make sure she was properly balanced and able to control Buddy. Mary decided she would stay on her knees, but lean her upper body across the couch, for more support. She also decide to put her shirt back on, to keeps his claws from digging into her flesh. Mary positioned herself against the couch. Without saying a word, Buddy knew exactly what was about to happen. He sprang to his feet and raced towards Mary. Before Mary could stop him, or at least slow him down, Buddy was up on Mary’s back, trying desperately to mount her yet again. Again, Mary felt Buddy’s dick poking her butt, trying to find his target. Mary reached around and grabbed his cock in and effort to slow him down and guide him, gently into her pussy. Buddy began to sink his cock into Mary’s snatch. Mary let out a moan and let go of his cock, thinking she was home free. Buddy pistoned in and out of her pussy a few times before slipping out. Mary again grabbed Buddy’s cock and slid it into her pussy, but unknowing to Mary, because of the way Mary was leaning up higher on the couch, it made her pussy too low for Buddy to stay inside her for more than a few second. Both Buddy and Mary were getting frustrated. Every time Buddy would hit home, he would thrust harder and faster, only to fall out again. This would only happen once more. Again, Buddy fell out, but before Mary could crab his cock, Buddy found another hole, Mary’s asshole. In one monstrous thrust, Buddy sunk three quarters of his cock into Mary’s virgin ass. Mary screamed in horror and agony. She was truly in some serious pain. Once again she screamed, fought, and begged for Buddy to stop, but Buddy had found a home for his baseball bat, and he was not to be denied. Mary felt as if someone was ripping her body in half, from the asshole up. Mary screamed, cried, and was digging her fingernails into the leather sofa, holding her up, tearing large holes in her couch. "Oh God Buddy, please stop, oh God it hurts, stop, stop, oh God please stop! Oh God, you’re hurting me, oh God please make him stop, oh fuck it hurts!" Meanwhile, Buddy was in doggy heaven. He was riding his new, tight, bitch like a jackhammer, burying his entire fourteen inches in Mary’s tight little ass, three or four times per second. This was one pain that Mary would never be able to get used too. Mary continued to scream and pound her fists on the couch and her feet against the floor. She was not sure if she could keep herself from passing out from the severity of the pain. Again she was begging Buddy, "Oh God please stop, it hurts so bad, please stop Buddy, please," she begged! "You're hurting me so bad, please, please, you have to stop!" But, it was no use. Little did Mary know, the worst was yet to come. After brutally ass raping Mary for about ten minutes, Buddy’s knot, now the size of a softball, was banging at her backdoor. Mary thought there was no way that knot would ever fit into her tight, little virgin ass, but Buddy was going to do all he could do to make that happen. Buddy continued to bang away at Mary’s ass, as Mary continued to cry, scream, and beg Buddy to get off of her, but Buddy was determined to knot with his bitch. Suddenly, Mary felt her asshole begin to rip apart even more. Buddy was knotting her. Mary’s pain was like nothing she had ever felt or even imagined. Compared to this, childbirth was like being hit in the face with a feather. Finally after straining to do so, Buddy had knotted with Mary. The long, hard, fast, thrusts were now slowed to a slow, short, humping, but the pain continued none the less. Another ten minutes had passed. By this time, Mary was wishing she could either pass out or just die. She could not take this brutal pain any longer. Then Buddy let out a yelp. All of a sudden Mary could feel her bowels begin to fill with hard spurts of hot doggie cum. Just as before, it felt as if Buddy was depositing a gallon of hot sperm inside of her. But this time she could actually feel her stomach and bowels start to expand, adding more to her pain. On top of everything else, her stomach was starting to cramp up with the irresistible feeling that if she did not take a dump soon, her insides were going to explode. After an additional fifteen minutes of Buddy filling her stomach with cum, Buddy had turned himself around, so again they were locked together, ass to ass. Mary knew the worst was over and now all she had to do was wait for the swelling in Buddy’s dick to go down and she would be free, never to try anything like that again. While Mary was waiting to be freed, she was thinking of how humiliating the past 18 hours had been and how low she had sunk, trying to fuck a dog. At least, she thought, no one would ever know about this and she could deal with her shame in private. Mary no sooner got those thoughts out of her mind when suddenly Buddy started barking and trying to run toward the front door, with Mary still attached to his dick by her asshole, being dragged across the floor. Then, suddenly, the door opened, and in walked her sister, Becky. "What the fuck are you doing" screamed Becky. There Mary was, being dragged across the living room, still knotted, ass to ass, with Buddy. All Mary could do was cry. Becky was Mary’s younger sister. Becky was the smart, wild, rebellious, and popular sister. Becky was a teacher. Becky was the one that always had a boyfriend or two and was never afraid to put out. Mary was always the good, angelic, sister. That is why Becky was so shocked by what she had walked in on. Becky ran over to her sister and tried to comfort her. Mary begged for Becky to get Buddy off of her. "I can do it," Becky said "but it is going to be a little weird." "I don’t care what you have to do," cried Mary "just get him out of my ass! Oh God, Becky, it hurts so bad!" Becky got down on the floor with them and began to stick her fingers in to Mary’s cunt and rubbing her clit at the same time. "Damn, you’re tight," Becky said "you’ve got to get yourself laid more often"" What the fuck are you doing to me?" Mary screamed. "If I pull him out of you the way he is now," Becky explained "you’ll be wearing diapers for the rest of your life. I have to get you relaxed and get to his knot, so I can massage it down, to get it out of you." Becky continued to push her hand into Mary’s pussy, adding one finger at a time, while continuing to rub Mary’s clit. Finally, Becky had her whole hand inside of Mary’s cunt. She felt around until she could feel Buddy’s cock and knot. Becky started to massage Buddy’s knot, to get it to shrink faster. Meanwhile, Mary’s pain and humiliation were at an all time high. There she was, in the middle of her living room, with her dog’s large cock stuck inside of her asshole, and her sister’s arm, half way up her pussy. Finally, after about ten minutes of massaging his knot, Becky was able to separate Buddy and Mary. Buddy pulled out with a loud pop. A huge waterfall of doggie cum, blood, and shit, poured out of Mary’s asshole. Again, Mary collapsed onto the floor and could not move. While Becky ran to get some towels to clean up Mary, Buddy began to lick out Mary’s still over-stretched asshole. Mary was too out of it to stop him, move, or even care. When Becky returned, she shooed Buddy away, and began to clean Mary up. The first thing Becky did was to shove a maxi pad up Mary’s ass, to stop the bleeding and absorb the leftover doggie cum. Becky managed to get Mary to her feet, in an attempt to get her into the bathroom. Mary’s asshole was so sore, every step she took was shear agony. Becky finally got Mary into the bathroom, cleaned her up, and put Mary to bed. Before Mary went to sleep, Becky asked what had happened and how did she get into that situation. Mary began to explain the events of the past 24 hours, begging Becky to never tell anyone what she had done, before falling fast asleep. While Mary slept, Becky went to the living room to clean up what mess was left that Buddy had not already licked up. After cleaning up the mess, both in the living room and bathroom, Becky put the towels and the blanket into the washing machine and went back in to check on Mary. Mary was sound asleep. Becky went back out to the living room, closing the door, to let Mary sleep in peace. Becky went out to the living room, got on the floor, and called Buddy over to her. As usual, Buddy came bouncing over to Becky, ready to play. Becky seemed to have a calming effect over Buddy. Becky began talking to Buddy. We have to teach you not to hurt Mommy, Becky whispered to Buddy. You can’t treat Mommy like a normal bitch, you have to be gentler. Mommy is sleeping now, Becky continued, so I will have to teach her later how to please you, but for now, you and I will have to work on this. Becky, still sitting on the living room floor, laid on her back, and crawled under Buddy. Becky reached up and started rubbing Buddy’s sheath. Instantly, Buddy’s dick began to grow. As soon as it was long enough, Becky began to suck on Buddy’s cock, as it continued to grow. Instinctively, Buddy began to hump against Becky’s face. Becky immediately stopped and sternly told Buddy no. She then braced her arms under Buddy’s hindquarters, so he could not hump against her face, as she continued sucking on his enormous cock. At first Buddy tried to fight against Becky’s arms, and continued to try to hump her face. But he quickly learned to stand still and let Becky do the work. As Buddy’s cock continued to grow, Becky took more and more of his cock into her mouth and down her throat, while at the same time, easing the grip she had on his hindquarters. Before too long, Becky noticed Buddy’s knot start to expand, eventually it began rubbing against her nose and lips as she took Buddy deeper down her throat. She knew Buddy was close to cumming. As Buddy’s excitement grew, he again started humping at Becky’s face. Becky again tightened her grip to stop him from humping. By now, Becky had Buddy’s entire cock in her mouth and down her throat. His knot was pressed tightly against Becky’s lips, continuing to expand. Becky knew that is was just a matter of seconds before she would have her belly full of one of her favorite snacks, doggie cum. As soon as Becky felt Buddy cumming into her belly, she began to pull back, so she could get some of Buddy’s hot cum in her mouth, so she could taste it and play with it. Becky was surprised how much cum Buddy was shooting. She figured after cumming for the third time in less than 24 hours, there would not be as much. She was wrong. Even an experienced cock sucker and cum swallower like Becky could not handle all of the cum being pump into her mouth and down her throat. Buddy had finally stopped cumming. Becky was still lying on the floor, enjoying what she had just accomplished. Becky could not believe how large Buddy’s cock had gotten. She had never seen such an enormous cock on a dog. Becky knew she had to have that cock. When she let go of Buddy, he immediately came to her and began licking up the excess cum that had poured down Becky’s face and neck. Becky just laid there and enjoyed it, but now she was getting horny. She felt the crotch of her shorts and noticed they were a little wet. "Are you ready to exchange the favor?" she asked Buddy. Becky got off of the floor and went over to the couch, pulled off her shorts and saturated panties, sat down, and spread her legs. "Okay Buddy," she said, "time for your next lesson, how to get Mommy off, without using that gorgeous cock of yours." Buddy needed no lessons on this, he knew exactly what to do. Within minutes, Becky was ripping off her shirt and bra, and was pulling and squeezing her ample breasts, leaning her head down, to suck on her own nipples. Buddy’s tongue was tunneling deep into Becky’s cunt, hitting all of the right spots, while his nose and teeth rubbed against her clit just right. Uncontrollably, Becky was bucking her hips up and down and in and out, against Buddy’s tongue. Finally, Becky had to start biting on a pillow, to keep from screaming and waking up her sister, as she had one incredible orgasm after another. Buddy was making Becky cum so hard, she began squirting her juices at and over Buddy’s face. Only one other time in Becky’s life had she squirted like that, and that took two other women, a big dildo, a large, vibrating, butt plug, and the most incredible pussy vibrator she had ever seen. Becky knew Buddy was a special dog and, with the proper training, Mary could be a very happy owner. After another 20 minutes of this, Becky could take no more. She was exhausted from cumming so hard for so long. She must have squirted at least 2 gallons of her own cum. She pushed Buddy away and praised him for being such a good doggie. Before getting dressed and again cleaning up the mess, she went to the kitchen to find a reward for Buddy. Becky found a large steak in the refrigerator that Mary had planned on making for herself during her weekend of freedom. Becky knew that Mary might be mad, but she figured that Buddy had earned a reward of that magnitude, plus she knew he would need the protein and energy to keep up with the training she had planned for later that day. After she got herself and her mess cleaned up, got dressed, and checked on Mary again, she decided to take a nap herself, on the couch. After Buddy finished his steak, he too took a nap, as he had worked as hard, if not harder, than any of them today. A couple hours later, Becky woke up and looked in on Mary. Mary was still in a deep sleep. Becky then went looking for Buddy. Where’s Aunt Becky’s big boy, she called out. Buddy came running. "Let’s take you outside, so you can take care of business," Becky said, "then when we come back in we can continue your training." Buddy ran for the door, like he knew exactly what Becky was saying. While Buddy was outside, Becky was setting up for Buddy’s next lesson, by gathering some fresh towels and setting up some pillows on the floor as well as the couch. Becky went to call for Buddy, but he was sitting at the door waiting for her. You know what’s coming, don’t you big boy, Becky said. Becky led Buddy to the living room and began to get undressed. "The first thing we are going to do," said Becky, "is see if you remember what you have already learned." Becky got on the floor and again crawled under Buddy and began rubbing at his sheath. Buddy’s cock popped out like a jack in the box. Becky put a pillow behind her head for support and began sucking on Buddy’s slimy, red dick. Instinctively, Buddy started to hump at Becky’s face, but as soon as Becky touched his hind end, he stopped. Becky sucked Buddy just long enough to get him hard, then pulled out from under him and got up onto the couch, while praising Buddy for remembering his training. Becky sat down on the couch and spread her legs wide. Buddy went straight to Becky’s pussy and began licking. "Oh God, you're good," Becky moaned, "get Aunt Becky good and wet!" Becky let Buddy continue to lick her pussy for a few more minutes before making him stop. "Okay Buddy, it’s time for your next lesson," Becky said, "This is something we are going to have to teach Mommy too, but first you and I need to work on this." Becky slid her ass to the edge of the couch, propped some pillows behind her back for support, and slapped her thighs to signal to Buddy to place his front paws up to the couch. Becky wrapped her legs around Buddy’s hind end and began to pull him closer. Becky then reached down and started rubbing Buddy’s cock as she lined it up to her pussy. Again, Buddy’s cock began to grow as Becky starting rubbing it up and down her pussy lips. After making sure they were both good and wet, Becky began sliding Buddy’s ever growing cock into her pussy. Buddy was a quick student and knew exactly what to do. He immediately started humping at Becky’s pussy, sinking three quarters of his monstrous cock into her pussy on the second thrust. Becky gasped at the sudden intrusion into her cunt. Buddy continued to pick up the pace, sinking his huge rod as deep as he could, into Becky’s wet pussy. Becky was in heaven, being fucked by such a large cock, but she knew her job was to train Buddy. Her pleasure had to come second. Becky tightened her legs around Buddy’s hind end, to slow him down. "Okay Buddy," Becky said, "as much as I am loving this, we have to slow you down. As tight as your Mommy is, you will rip her to pieces, fucking her like that. Once we get your Mommy loosened up, she may enjoy it as much as I do, but until then, you have to go slow and easy." Becky continued to control Buddy’s pace with her legs as he learned to control his thrusts. Slowly, Becky eased her grip on Buddy’s hips, to see if he would continue to control his thrusts. Buddy was doing very well at his training, but as his knot began to expand, he again started to pick up his pace. Again, Becky tightened her grip on his hindquarters, to try to slow him down. Buddy learned quickly and slowed his thrust. Now Becky was able to completely release her grip on Buddy’s hind end. Buddy tried his best to bury his knot in Becky’s pussy, but in this position, it was not going to be easy. Becky knew she would have to help him. Becky too wanted to feel that large knot in her cunt. Her lust was starting to get the best of her. She knew she needed to continue to train Buddy, for Mary’s sake, but she desperately wanted that knot in her pussy, and wanted to cum too. Finally, Becky gave into her lust, pushed Buddy out of her, got down on the floor, on her hands and knees, and let Buddy’s instinct take over. Becky was no sooner on the floor than Buddy was up on her back, humping full tilt. Becky reached back, grabbed Buddy’s dick, and placed it at the entrance to her dripping pussy. That was all of the help Buddy needed. In one big thrust, Buddy buried his entire cock in Becky’s pussy. All Becky could do was moan. "Oh yes, oh fuck, fuck that feels good! Fuck me you beast, fuck me good! Fuck me, oh God fuck me! Deeper, oh God fuck me deep, bury that fucking cock in my cunt, bury that knot in my fucking pussy!" Becky was heading for nirvana. All she needed was to get Buddy’s knot deep inside of her to make it complete. With a few more thrusts, Becky and Buddy were knotted. Becky was thrusting backwards toward Buddy to meet each of his thrust. Becky was biting her lip to keep from screaming out in ecstasy. "Oh yes, God yes, fuck me, fuck me hard you beast." Becky continued to moan. Becky wanted to scream out as loud as she could, but she knew she could not or she would wake up Mary. Buddy continued to pound Becky’s cunt. Becky could feel Buddy’s knot continuing to expand and stretch her snatch to its limit. She knew from experience from the swelling of Buddy’s knot and the pulsing of his cock, he would soon be filling her womb with his thick, hot cum. This thought alone sent Becky into yet another screaming orgasm. She tried her best to mute her sounds, but it was almost beyond her control. Becky managed to reach a pillow and buried her face in it, screaming, as yet another orgasm washed over her. Buddy could wait no more. He finally started unloading the contents of his nuts into Becky’s womb. As soon as Becky felt his first spurt, she again began screaming into her pillow. "Yes, yes, oh God yes! Fill me with your cum! Slam me, fuck me, fill me with all you got baby," Becky continued to scream. Five orgasms and ten minutes later, Buddy’s nuts were finally empty and he was beginning to turn himself around. Becky just laid her head on her pillow, gasping for breath, and moaning unintelligible. After regaining her senses, Becky said to Buddy "You are the best fuck I have ever had, and I have had a few. I have never had a man, woman, or beast as good as you." she continued. After being knotted for about 25 minutes, Buddy was finally able to pull out of Becky. Before too much cum was able to escape Becky’s snatch, Becky was able to roll over on her back and tighten her pussy muscles in order to keep Buddy’s hot cum locked inside of her, until she was ready to let it go. At first, Becky pushed out just enough to fill her hand and scoop the cum up to her mouth. Becky put the handful of cum into her mouth and let it slosh around her mouth for a few minutes before finally swallowing it. While Becky was sucking on the cum in her mouth, she forced out another hand full and rubbed it over her ample, "D" cup breasts. Immediately, Buddy started licking the cum from Becky’s tits and nipples, which was exactly what she wanted. Becky reached down for yet another hand full of cum and again put it in her mouth. Once Buddy licked all of his cum from Becky’s tits and face, she finally let loose of her pussy muscles and let the remainder of Buddy’s cum flow out of her pussy and down her ass. This quickly caught Buddy’s attention and he went down and began eating at Becky’s cunt and asshole. This again was exactly what Becky wanted. This brought Becky to several more, mind shattering orgasms. After the most incredible sexual experience of her life, Becky was spent. After lying on the floor catching her breath and regaining her composure, Becky decide to get up and take a shower. Even after all of that, Becky continued to finger herself as she showered. After getting out of the shower and getting dressed, Becky decided she needed something to eat. As she walked to the kitchen, she had to step over an exhausted Buddy. What a lightweight, Becky said to herself, as she went by the sleeping dog. Get some rest, Becky told Buddy, we still have a lot more work to do. After eating, Becky decided she needed to figure out a way, to control Buddy’s thrust, when he fucks doggie style. She did not mind the way Buddy did it, but she knew Mary could not handle it, at least in the beginning. Becky decided Mary had the right idea using the couch for leverage, but it was obviously too high, unless you wanted to take it up the ass, which Becky would not mind either. Becky decided the footstool would work better. It was high enough to give support, but low enough to keep Buddy in her pussy. It was also small enough to allow Becky to reach back and hold Buddy’s hindquarters to control his thrusts. Becky looked over at Buddy and decided she would wait a little longer and allow Buddy to recover a little more. She also noticed it was starting to get dark outside. She did not realize how late it was getting. She decided she wanted to spend the night and continue her work with Buddy. Becky went to the phone and called her husband. She told her husband Mary was not feeling well and she wanted to stay and keep and eye on her, which was not exactly a lie, she just did not tell him the whole truth. After talking to her husband, she went back in to check on Mary. The light from opening the door hit Mary directly in the face. She jumped as Becky walked into the room. "It’s okay," Becky said, "it’s just me. I just wanted to check on you." Mary was still half-asleep and confused. "What happened, what’s going on, what time is it?" Mary asked. "It’s okay" Becky replied, "it’s about seven o’clock. I’m here, I have already taken care of Buddy. I just wanted to check on you, how are you feeling?" "Oh God, my asshole hurts." Mary replied. "How can you enjoy getting fucked up the ass?" Mary asked Becky. "Well, it helps if the first time you do it, you don’t do it with a dog, with a dick the size of a baseball bat and a knot the size of a bowling ball." Becky replied. "I will never do anything like that again." said Mary. "Don’t go making any decisions now while you are in this state of mind you may regret later." Becky said. Mary looked at Becky kind of puzzled, but her mind was still in too much of a fog to care. Becky pulled down the blankets and began to lift Mary’s nightshirt. "What are you doing?" Mary barked. "I want to check the pad I put against your asshole, and I need to check and make sure you did not do any permanent damage to yourself." Becky answered. As Becky pulled the pad away from Mary’s ass, she noticed a little blood and some doggie cum, but it appeared not to be fresh. "Don’t move," Becky ordered Mary, "I’ll be right back, I want to get another pad, just to be safe." Becky knew that if she wanted to continue with Buddy’s training, she needed her sister out of the way. Becky went to her purse and pulled out a couple of pills she knew would relax Mary as well as put her to sleep until morning. Becky soon returned with a fresh pad, a couple of pills, and a glass of water. "Take these." Becky told Mary. "What are these for?" asked Mary. "They will make you feel better. Now take them and shut up!" Becky demanded. After Mary swallowed the pills, Becky went back to work on Mary. Becky shoved a finger up Mary’s ass. "What the fuck?" Mary screamed. "I told you," Becky said, I need to make sure you did not hurt yourself permanently." Becky felt Mary’s asshole and it was still good and tight. " It looks like you’ll be okay," Becky said, "now lie back, relax, and try to go back to sleep." "How am I supposed to relax with your finger up my ass?" Mary barked. "Shut up, go to sleep, and trust me." Becky barked back. Becky took her other hand, licked her fingers, and began rubbing them against Mary’s pussy and clit. "Oh God Becky, what are you doing?" Mary cried. "Just close your eyes, relax, and enjoy it." Becky replied. "You need to learn to let yourself enjoy things when they are presented to you." Becky slowly worked one finger than another into Mary’s still tight pussy, while still massaging her clit, and stimulating her asshole with her other hand. Again, Mary started to object. Before Mary could finish her statement, Becky cut her off. "Be quiet, relax, and enjoy it. Now, I want you to lie back, relax, close your eyes, and imagine your being pleasured by the sexiest man you can think of." Becky continued. It took a few minutes for Mary to relax and accept what Becky was doing to her, but eventually, she allowed her self to push away the thoughts that this was wrong and concentrate on how good Becky was making her feel. Ten more minutes went by. Becky now had 3 finger buried deep into Mary’s cunt, while continuing to rub her clit and stimulate her asshole. Mary had finally let herself go. She was moaning quietly, "Oh yes baby, fuck me, fuck me good, make me cum baby, make me cum." Becky now decided to go one step further. Becky lay down on the bed, put her face between Mary’s legs, and began licking her pussy. This again shocked Mary. "Becky stop, this is wrong, we shouldn’t be doing this!" Mary said. Becky just ignored Mary this time and continued eating out Mary’s pussy, while still keeping her fingers in her cunt and asshole. Mary continued moaning with pleasure. "Oh God that feels so good." Mary mumbled. "Oh God Becky, you’re going to make me cum, don’t stop, please don’t stop. Yes, yes, right there, oh fuck yes, fuck it, oh God, fuck it, that’s the spot, don’t stop." Becky started to intensify her efforts, licking, sucking, stimulating, and finger fucking Mary harder and faster. Mary started to shake uncontrollably. Her orgasm was only seconds way. "Oh God, yes," Mary cried out, "I’m going to cum. Oh God you’re going to make cum!" Mary’s entire body began to shake. "Oh God, I’m cumming, yes, yes, oh fuck yes, I’m cumming!" Becky started slowing down her efforts and pulling her finger out of Mary’s ass. She continued to lightly rub at Mary’s clit, as one by one, she starting pulling her fingers from Mary’s pussy. Mary let out a loud sigh, "Oh God, that was great." she mumbled. Becky could tell the pills Mary took were starting to take effect. Becky pulled away from Mary, put a maxi pad against both her pussy and asshole, to help absorb her juices. She pulled Mary’s panties back up, pulled down her nightshirt, and put the covers back over her. Becky walked up to the head of the bed, gave Mary a light kiss and said, "We should do that again sometime. You get some sleep," she continued, you don’t know it yet, but you have a big day ahead of you tomorrow." Mary mumbled something that Becky could not understand and was fast asleep for the night. Becky left the room, closing the door behind her. Now back to the task at hand, Becky thought to herself as she walked down the hall looking for Buddy once again. Becky returned to the living room, where she had her pillows, blanket, and footstool set up. "Well Buddy," Becky asked "are you ready for your next lesson? I know I am." she continued. Becky had made herself very horny getting Mary off. She now needed some release for herself. Becky again started taking her clothes off and was getting ready to assume the position. Buddy came bouncing over to Becky. He knew what was about to happen and was getting excited, yet again. Buddy immediately stuck his snout into Becky’s crotch. Becky knew she only had the rest of the night to complete Buddy’s training, but she was also extremely horny. She had just spent the better part of an hour playing with and eating out her sister’s cunt, not to mention finger fucking her ass, with no retribution for her. More and more Becky was leaning towards pleasuring herself and putting off Buddy’s training for a couple more hours. She was aching for a good butt fucking herself, her only concern was how many good fucks Buddy had left in him tonight. Becky sat down on the floor, with her back against the couch and her legs spread wide open. Buddy immediately dove into her pussy and began licking as if his life depended on. "Oh Buddy," Becky moaned "how did you get so good at this so fast, God you are incredible!" Within minutes Becky was flooded with one incredible orgasm after another, again squirting her cum all over the floor and on Buddy. Becky was pulling and squeezing her tits so hard, they were blood red. The harder she pinched her nipples, the harder she would cum. "Oh God, oh God, oh my fucking God," Becky continued to moan "I have got to get that log of yours in my ass before I completely explode." Becky turned over, got on her knees, and leaned over the couch, just as Mary had, when Buddy raped her ass. Becky managed to scoop up enough of her own cum, along with Buddy’s saliva, to lubricate her asshole. Buddy jumped on Becky’s back and started hump wildly. Becky reached back, grabbed Buddy’s cock, and positioned it at the entrance to her asshole. Buddy took the cue, and sunk his still growing cock straight into Becky’s ass. Becky gasped with a combination of pain and pleasure. Becky had participated in anal sex many times, with men, dildos, and beasts, but never with anything as big as Buddy’s cock, not to mention his huge knot, that was soon to come. Buddy was now at his full size, burying his entire cock in Becky’s asshole with every thrust. Becky, now used to his incredible size, was bucking back at Buddy, matching him thrust for thrust, moaning uncontrollably. "Fuck me, you son of bitch, ride me hard, make me your fucking bitch." Becky moaned. Becky could feel Buddy’s knot expanding and beginning to push up against her ass. For the first time in Becky’s long sexual history, she was beginning to wonder if even she would be able to handle Buddy’s knot penetrating her asshole. She would soon find out. Becky continued moaning and crying out in ecstasy. Buddy was now ready to knot his bitch. Becky, still unsure if she could handle it, was about to find out. Buddy started pushing his knot harder against Becky’s sphincter. She could feel her asshole begin to stretch to new limits and this was just the beginning. Another couple of thrusts and Buddy’s knot was only half way into Becky’s ass. Becky buried her face into the couch cushion, screaming bloody murder. She was not sure how much more of this she could take. Becky’s asshole was now stretched wider than it had ever been stretched before. Wider than Becky ever thought was humanly possible. This was way beyond anything she had ever attempted to butt fuck in her life. As Buddy continued pushing his enormous knot into Becky’s ass, she began going into uncontrollable convulsions. Her brain was being completely overwhelmed with pain and pleasure. Her head was swinging, almost uncontrollably side to side. Becky was beating her fists into the couch and kicking her feet up and down, against the floor. Becky was not sure how much longer she could remain conscious. She was fighting to stay awake. She did not want to miss even one second of this incredible, sexual, experience. Finally, with one last, tremendous thrust, Becky and Buddy were knotted. Now that Buddy’s knot had made it past Becky’s sphincter, the pain began to quickly turn into pleasure. Once again, orgasms were crashing down on Becky like waves against the shore. She was again squirting her cum, in almost one constant stream. Becky had reached a new sexual high, unlike anything she had ever experienced. "Oh my God, Jesus fucking Christ, she continued to scream. Keep on riding me baby, let Aunt Becky have all you’ve got! Fuck me like I have never been fucked before! Fill me with your cum, make me fucking explode! Oh fuck, I could die right now, the happiest woman on the planet, she continued to moan! Oh my God you are fucking incredible! I wish this feeling would never end!" Becky now started to feel that familiar feeling. Buddy’s cock was starting to swell and pulsate. Becky knew it was just a matter of seconds before her bowels would be filled with that wonderfully hot, doggie cum. This thought alone brought on yet another squirting orgasm. How can something that is so wrong, feel so fucking great, she thought to herself. If more women would try this, she continued to think, this would never be considered so taboo. Becky tried to bear down with her asshole to try and keep Buddy from blowing his load so soon, but she knew this awesome feeling could not last forever, no matter how hard she tried, or how bad she wanted it too. Bearing down did not hold back Buddy’s cum for very long. What it did do however, was allow Buddy to cum with more force than ever before. When Buddy finally did start blowing his load, Becky felt as if a hot, wet, cannon was being shot into her bowels. Becky tried to continue to bear down as long as she could, which also helped to increase the intensity of her own orgasms, but, with having so many intense orgasms continuously, she was too exhausted to hold it any longer. Finally she gave up and just enjoyed the feeling of Buddy emptying his nuts into her ass, giving her one final orgasm. After another ten minutes of Buddy spraying his sperm into Becky’s ass, he had finally finished and began to turn himself around, locking Becky and Buddy together ass to ass. Becky just laid her head down on the couch to try to catch her breath and regain her senses, while enjoying the feeling of that warm cum still in her stomach and bowels. Becky and Buddy remained knotted for another 25 minutes before Buddy was finally able to free himself from the clenches of Becky’s ass. Unlike the last time they fucked, Becky was too tired to hold in Buddy’s cum. Buddy’s cum poured out of Becky’s ass, like water through a hose, straight onto the floor. Between all of the cum Becky had squirted and all of the doggie cum she had just deposited on the floor, there was a very large pool of cum on the floor. Becky could not help herself, she had to lie down in the pool of cum, rolling around, spreading it over her entire body. She also managed to scoop up a few handfuls of this cum cocktail, playing with it in her mouth before finally swallowing it. While Becky was on the floor playing and eating all of the cum, Buddy decided to get in on the act. Buddy began by licking up the cum on the floor that Becky had missed or not gotten to yet. Once all of that cum was gone, Buddy began to lick at Becky’s body. Buddy started at her feet and meticulously worked his way over her entire body, paying special attention to her asshole and pussy. Needless to say, this triggered another series of orgasms for Becky. Her orgasms were not near as intense as her previous fuck session, but they were good orgasms none the less. Once all of the cum was licked up, Buddy found a quiet corner to lie down in and clean himself, before falling asleep. Despite Buddy’s best efforts, Becky too needed to get cleaned up. Becky took a quick shower, this time not taking the time to masturbate. After Becky got out of the shower, she stuck her head in to check on Mary, and then decided she needed to go to sleep herself. Becky knew she still needed to complete Buddy’s training before Mary woke up in the morning, but she figured both her and Buddy needed a rest and time to recover from their very long and intense fuck session. After a couple of hours nap, Becky would be good to go yet again. She only hoped Buddy would be too. Becky slept for almost three hours. It seemed to Becky, she spent the entire time dreaming about getting fucked. Needless to say, Becky was horny, wet, and ready to continue Buddy’s training, for Mary’s sake of course. Before heading out to the living room, Becky again looked in on Mary, to make sure she was still sleeping. All was safe. Mary was still asleep, now on with the training. Becky went to the living room and again set up the footstool and pillows that got shoved aside during her last fuck session. Becky knew she needed to get on to Buddy’s next lesson before indulging her own lust. It was just after midnight and she knew Mary was an early riser. She had to finish Buddy’s training in time for Mary’s early surprise and give Buddy enough time to recover at the same time. Becky’s worries about Buddy were soon put to rest. Becky was just beginning to set up her stool and pillows as Buddy came over and began licking at the wet spot in the crotch of Becky’s shorts. You’re a horny little guy, now aren’t you Becky said. Just give me a minute to get set up and we’ll get back to work. Becky quickly took her shorts off to let Buddy have free access to her pussy while she continued laying out her pillows. Between Buddy’s saliva and Becky being so horny, it did not take very long for her pussy juices to start running down her legs. Becky had never been with anybody, or anything, that could get her juices flowing like Buddy had. Becky knew she would be visiting her sister a lot more often from now on. Becky continued taking her time getting the pillow set as she enjoyed Buddy lapping away at her. His tongue was reaching from her clit to her asshole, causing Becky to explode in orgasm all most immediately. "You are a fucking God." Becky moaned, "I have got to stop letting you do this to me, we are never going to get your training finished. If it were just me, you go stay like you are forever, but your Mommy can’t handle you like that. But don’t worry, we will get her broken in. In the meantime." Becky continued, "I will visit you as often as I can and you can have your way with me all you want." Fortunately for Becky, with Mary’s hectic schedule, she was almost never home during the day. After Becky’s husband left for work and Becky dropped her kids off at school and daycare, she had the whole day to herself. "Okay Buddy, let’s try this again." Becky said as she got down on her knees, leaning over the stool. Buddy immediately jumped on Becky’s back and started poking his growing rod furiously at Becky’s ass. Becky quickly reached back and put her hands on Buddy’s hips, almost stopping his humping. "Okay big boy, this is where you have to go easy on your Mommy." Becky told Buddy. Becky grabbed Buddy’s cock and lined it up with her pussy and allowed him to penetrate her slowly. Becky was only allowing Buddy in about half way to teach him to how to be slow and gentle with Mary. At first Buddy was fighting hard against Becky’s arms, but quickly learned his slower pace. As a reward, Becky allowed him to penetrate her a little deeper. This was as much a reward for her as it was for him. Becky slowly eased her grip against Buddy’s hips as he learned to enjoy this slower, easier pace. Eventually, she was able to completely drop her arms, as Buddy kept going at this pace. Buddy continued this pace and slowly sank the remainder of his cock into Becky’s slit. With his cock now completely buried in Becky cunt, he continued to keep his slow pace. Despite the slower pace, Becky was still having great orgasms. "Oh baby, you’re almost as good slow as you are fast." Becky moaned "That cock of yours is magic. Oh fuck I wish I could let you pile drive me." she continued "God you are incredible!" Buddy continued fucking away at Becky at his new, slower pace. Becky's orgasms continued to flow, one after another. Becky was fighting back every urge in her body to start slamming her pussy back at Buddy’s cock. After about another ten minutes of this, Becky was beginning to feel Buddy’s knot push up against her snatch. Now she really wanted to lunge back to bury that rock in her pussy, but she allowed Buddy to continue at his pace. Becky knew Buddy would have to pick up the pace to knot her, but the test would be how well Buddy would be able to control himself. The lust in Becky hoped he would fail miserably, but the teacher in her wanted him to do it right. For better or worse, Buddy passed the test and once again Becky and Buddy were tied together. Now that there was no way for Buddy to get overly brutal, Becky began thrusting back at Buddy. This did wonders for increasing the intensity of Becky’s orgasms. Within no time, Becky was again screaming into her pillow and squirting like a fire hose. Becky had left her shirt on this time, because Buddy’s claws were scratching her so much, she was beginning to bleed. She was now sorry she did. She loved playing with her own breasts and sucking and biting her nipples during the height of her orgasms. Becky could no longer stand not being able to get to her tits. In the heat of ecstasy, she finally ripped open the front of her shirt and started squeezing her tits until they turned dark red. It may not have been the style of fucking Becky was used to, but she was loving it nontheless. Buddy had been fucking Becky for almost 35 minutes, being knotted for the last 15 of those minutes. This may not be Becky’s favorite fucking pace, but she noticed that Buddy lasted longer at this pace. That was a definite plus, Becky had lost count of her non-stop orgasms at least 10 minutes ago. But Becky could feel the end was coming, as Buddy’s pulsating cock told her she would soon be filled once again with Buddy’s hot, thick seed. No sooner had Becky finished that thought, then she felt the first shot of Buddy’s fiery cum starting to once again fill her womb. As before, this sent her orgasms into overdrive, squirting what felt like gallons of her cum, down her legs and onto the floor. Buddy and Becky had now been fucking, non-stop, for close to an hour. Buddy had finished emptying his balls into Becky’s womb and had turned himself around, tying them ass to ass once again. Becky had thought, she cannot remember ever fucking a dog for this long. Maybe there was something to this slower paced fucking. However, Becky had made up her mind that, before the night was over, she was going to get fucked her way, at least, one last time. Twice if she was lucky, Becky had hoped to be able to get it up the ass one more time too. Becky continued to kill the time she had left being tied to Buddy by fantasising about what she wished could be. About the only thing that she could thing of to make Buddy better was if he had two cocks. That way she could take it up the ass at the same time he was pile driving her cunt. Becky loved a good double penetration. Becky wished she had brought a dildo with her, but how was she to know what she was walking into when she stopped by. Becky made a mental note to bring one with her the next time she visited Buddy. It was now close to an hour and a half since Buddy and Becky has started their latest fuck training session. Becky’s knees were getting sore. Despite the fact she loved the felling of Buddy’s knot being stuffed deep into her cunt, she was a little relieved when Buddy had finally shrunk enough to pull out. Once again Becky was able to hold Buddy’s spunk inside of her, so she could dispense whatever amount she wanted, a little at a time. This time however, Becky decided to get a large cup and emptied the contents of her womb into it. Becky decided to leave Buddy alone to lick up her cum off the floor while she went into the bathroom, laid down in the tub, and slowly poured the still warm cum all over her body. This was not the first time she had ever done this, but it had been a long time ago. Becky had forgotten how good it felt to spread Buddy’s warm seed over every inch of her luscious, tight body. Becky especially enjoyed massaging the hot cum into her large, full breasts. Becky would rub it into her breasts and then lick them clean. She repeated this several times, bringing herself to orgasm each time. Becky could not remember ever having so many orgasms in one day in her long sexual life. Becky could remember masturbating herself to orgasm as early as seven years old, most days doing it 3 or 4 times a day, some days even more. She had spent long weekends before, doing nothing but fucking every waking hour, several times with multiple partners, but still never cumming as much, as fast, or has hard, as she had in the past 8 hours. Before morning, she knew her total orgasm count would easily be in the triple digits. Between licking it off her body and drinking it straight out of the cup, Becky managed to swallow almost Buddy’s entire load. What was left had now dried to her body and Becky needed another shower. Becky just let the warm water run down her body, before caressing her skin as she soaped up. This managed to get Becky clean as well as horny, yet again. She wanted to get out and go straight for Buddy and have at it all over again, but she knew Buddy would need a little more time to recover. Becky would just have to wait and allow the lust to build. She knew that would make her next fuck session just that much better. Becky did not bother getting dressed again. She knew it would just be a matter of time before she would be doing Buddy yet again. Plus, she now had no shirt to put on, as she ripped the shirt she wearing to pieces while in a lust induced rage during their last fuck session. Becky would have to borrow one of Mary’s shirts to drive home, if she could find one that would fit. Mary had a smaller, petite figure, with small, just barely "C" cup breast, while Becky had a larger frame, with large, full, "D" cups, almost bordering on "DD" cups. She knew even a large shirt of Mary’s would still be a tight fit. Anyone seeing her driving home would surely get a thrill, especially if she did not bother to wear a bra. She had a bra she could wear home, but she loved to give guys a peak at her body, just to tease them, even if she never saw them again, she would give them something to remember. Becky went back out to the living room and lay down on the couch while giving Buddy time to recuperate. Becky fell asleep for about 45 minutes, only to be awaken by a large, warm, tongue lapping deep into her cunt. Becky was startled at first, but loved being woken up this way. At first she thought she might have been dreaming, until that first orgasm hit, then she was wide-awake. "Oh God Buddy," Becky moaned "you must have been reading my mind. I was just dreaming about you. You had 2 dicks and you were fucking the shit out my pussy and my ass. You were incredible. Oh fuck, you were incredible." Becky continued to let Buddy eat away at her pussy, still fantasying about being double fucked. She wished so badly that she had brought a dildo with her. Becky doubted, very seriously, that Mary would have a dildo, seeing as her pussy was so tight when she was fingering her sister and how tight it was when she shoved her fist into her sister’s cunt, trying to massage Buddy’s knot when Buddy had tied Mary up the ass. Even if she did, it would most likely be hidden in her bedroom and Becky did not want to take a chance at waking up Mary. She still had more plans for her and Buddy tonight. Between orgasms, Becky peered around the parts of the house she could see, for something she could improvise with, but saw nothing. After about her fifth orgasm, Becky decided it was time to make Buddy stop and move on to better things. "I hate to interrupt your meal," Becky said to Buddy "but you have not been out in hours and I need something to drink." Becky sat up and pushed Buddy’s head aside to stop him. "Come on big boy," Becky continued "lets go outside so you can do your business. I promise, as soon as you get back in, we will finish what you started." Becky opened the door and Buddy raced out to the back yard. While Buddy was outside, Becky went to the refrigerator to grab a drink. Becky was looking around, trying to decide what she wanted to drink, when she spotted the perfect thing, a large cucumber. That would work just fine in place of a dildo or another cock. Becky pulled out a 12-inch cucumber that she could not even close her hand around. It was huge and it was going to be perfect. Becky grabbed the cucumber and a bottle of virgin olive oil and headed for the living room. Becky could not help but laugh about using virgin olive oil, boy is that a far stretch she thought to herself. Becky went to go call for Buddy, but just as before, Buddy was standing at the door waiting for her. As soon as she opened the door, Buddy ran straight to the living room and turned and looked back at Becky as if to say, what are we waiting for? You look as horny as I feel, Becky told Buddy as she made her way over to Buddy. Okay boy, before we get down to some major, hardcore fucking, we need to make sure you remember everything we have worked on. Think of this as your final exam, Becky continued, if you pass this test, we can celebrate for the rest of the night. Becky started by getting on the floor, laying on her back, crawled underneath Buddy, and began giving Buddy a blowjob. For a second, Buddy started to hump at Becky’s face, but all Becky had to do was lightly touch his hip and he stopped instantly. Becky continued sucking Buddy’s cock for about 5 minutes. Becky then got up and moved to the couch to test Buddy on his next position. Once again Becky slid her ass to end of the couch and signaled for Buddy to put his front paws up on the couch. Buddy’s cock, still partially erect from the blowjob he had just received, was lined up with Becky’s snatch, and he gently pushed his way into Becky’s wet pussy. "You are such a good boy," Becky praised, "you are passing your test with flying colors." Becky only allowed Buddy to fuck her in that position for a couple of minutes. She did not want Buddy getting overly worked up until they were ready to do some hardcore fucking. As soon as Becky saw Buddy’s knot start to expand she stopped him and pulled him out and tried to calm him down before the last part of the test. Then they could spend the rest of the night going at it hot and heavy. Becky moved from the couch, back to the floor. This time she got on her hands and knees. Becky did not bother with the footstool and pillows this time. She knew that if Buddy continued to be as gentle as he had been in the previous two activities, she would not need the extra support. Buddy quickly jump up on Becky’s back and started poking his rod at her ass. Becky reached back and lined up his dick with her pussy. Buddy began slowly sinking his rod into Becky’s love canal, just as he had been taught. Again, Becky only let this go on for a couple of minutes. Buddy had passed his test with flying colors. Much to Buddy’s dismay, Becky made Buddy stop. Becky turned around, sat up, pulled Buddy close, and began petting and praising Buddy. "You are such a good, big boy. You did every thing you were taught just perfectly. Now all we need to do is get your Mommy trained and you two should live happily ever after." Now that Becky had finished teaching Buddy how to fuck in a gentler manner, she knew the rest of the night was hers to do with as she pleased. Those thoughts alone had Becky’s pussy getting wetter by the second. Now Becky had to decide what to do next. She was not sure if she wanted Buddy to fuck her pussy while she shoved her cucumber up her ass, or did she want to let Buddy have her asshole while she fucked the cucumber with her pussy. Becky knew whichever way she decided she was going to need to loosen and lubricate her asshole. She really loved it when Buddy fucked her ass earlier, but she knew Buddy had almost ripped her asshole to pieces. She also realized the girth of the cucumber could do some damage too. Becky spent a few minutes shoving her well oiled fingers in and out of her asshole, while trying to make up her mind as to who and what was going to fuck her where. Becky finally decided that since Buddy had fucked her pussy the last time they fucked, she was going to let him fuck her ass this time. Becky thought it would be a good idea to rotate back and forth, allowing Buddy to fuck her ass again this time, giving her pussy a rest and time to tighten up, then, hopefully, they would have time for one last fuck, this time in her pussy, before dawn. Before returning to her hands and knees, Becky took the cucumber and began rubbing it with oil. She then started to rub it up and down against the entrance of her love canal. After teasing herself with for a few minutes, Becky started to push the cucumber into her cunt. Oh yes that feels good she moaned. Becky pulled the cucumber in and out of her pussy, each time pushing it in a little deeper, until finally she had the whole thing buried in her cunt. Meanwhile, Buddy was starting to get a little impatient, not to mention getting even hornier. Finally Buddy gave out a yelp to let Becky know he wanted to get back to fucking. Becky pulled out her cucumber. She thought she better wait until Buddy had his dick planted securely up her ass before shoving her second dick into her pussy. As big as Buddy was, it was hard enough to get his entire cock in her asshole. She did not want to take a chance that he would not be able to get his cock all the way in her ass, with the added pressure of her cucumber pushing back at him. Once again Becky rolled over and got on her hands and knees. Buddy wasted no time jumping up on her back, jabbing his dick at her butt. Becky reached back, grabbed Buddy’s dick, and lined it up with her asshole. In one massive thrust, Buddy buried his entire cock in Becky’s asshole. Even though Becky was very experienced in taking it up the ass, having Buddy’s huge cock buried in her ass so quickly, took her by surprise and took her breath away. As soon as she caught her breath, Becky let out a deep- throated moan. "Oh, my fucking God, so are so fucking huge, oh fuck that hurts." Becky continued to moan! For Becky to be in so much pain from an ass fucking, she knew Buddy’s cock was the most monstrous thing she had ever taken up her ass. He felt even bigger than the first time he fucked her ass a few hours ago, and his knot was not even close to penetrating her yet. Buddy continued plowing Becky’s ass like a racecar piston at the Daytona 500. Becky was still experiencing pain, but she was slowly getting used to it. She was squeezing her tits so tightly, they were turning purple. If she had not kept her fingernails so short, she would surely be drawing blood by now. Becky’s deep- throated moans continued. "Oh yes, fuck yes, fuck the living shit out of me you fucking beast! Fuck me like the bitch I am, fuck me baby, oh God fuck me!" Becky was finally adjusting to sudden intrusion of her asshole and could feel her orgasms starting to build. It would only be a matter of minutes before she would be cumming like a wild woman. Becky decided it was time for her second cock. Becky grabbed her cucumber and began rubbing it against her pussy. Buddy was humping at Becky so hard and so fast, it was hard for her to keep her balance on just one arm while trying to insert her second cock into her cunt. She knew she could not hold on much longer. She knew she did not have much time to play. She was either going to have to shove it in now or forget it. Becky wanted that double penetration badly. Becky knew she needed to work that extra large cucumber up her cunt slowly, or it was going to hurt. If she was going to make this work, she had to do it fast or not at all, as she could not hang on with just one arm much longer, especially once her orgasms started crashing down on her, which would not be long. Becky lust for a double penetration was quickly overcoming her fears of the pain that giant cucumber would cause. With Buddy fucking Becky’s ass so fast and furious, her pussy was dripping with pussy juice, which helped lubricate Becky’s cucumber. Becky lined up the cucumber with the opening of her cunt, took a deep breath, and shoved it in as deep as she could push it, burying the entire foot long vegetable in her cunt. With Buddy’s huge cock buried to the hilt in Becky’s ass, her cunt was tighter than it had been since she lost her virginity. The combination of pain and pleasure caused Becky to scream and buck uncontrollably. Becky quickly shoved a pillow in her mouth as not to wake up Mary, or the rest of the neighborhood. The double penetration immediately brought on the first of what seemed like thousands of mind-blowing orgasms. Becky was now bucking like she was ridding a mechanical bull. She was again squirting her pussy juices. Becky was squirting so hard now, that her juices were hitting the floor, bouncing back and splashing against her belly. "Oh yes! Fuck, oh fuck, oh fuck, oh fuck! Oh my fucking god! Holy shit, oh fuck," she continued screaming into the pillow clenched between her teeth. Becky’s holes had never been so full. Her orgasms were coming so fast and so hard, she could not tell where one stopped and the next one started. Becky was as close to nirvana as she had ever been before, yet she knew the best was yet to come. Becky was beginning to feel Buddy’s knot pounding against her ass. She knew it would only be a matter of minutes before Buddy would be trying to force that knot into her already overly stretched asshole. Becky was wondering if she would even be able to take Buddy’s knot into her asshole. She was able to take it earlier, but she now had a foot long cucumber shoved up her snatch that, at its largest point, was as big as a baseball in diameter. How much more could her holes be stretched? How much more could her body and mind take? She would soon find out. Every time Buddy thrust his cock into Becky’s ass, she could now feel his growing knot press against her asshole. Becky took a deep breath, trying to relax her body enough, to allow her asshole to expand wide enough to accept his knot. Becky now had to really brace herself as Buddy’s thrust were like getting hit with a Mack truck as he tried to bury his knot deep in to Becky’s ass. Buddy was determined he was going to knot this bitch. Becky could feel her already over stretched ass begin to stretch even more. She was beginning to feel as if her asshole was no longer stretching, but tearing instead. Becky now was feeling more pain than pleasure. She was beginning to wonder if maybe she had gone too far in her search for sexual heaven. Becky decided if she was going to survive this experience, without doing any permanent damage, she must remove that cucumber from her pussy. Becky tried to reach back and grab her second cock, but as soon as her arm left the ground, Buddy’s pounding hips knocked her off balance and she lunged forward, pushing her face to the floor. This sudden shift forward was all the extra momentum Buddy needed to shove his knot into Becky’s sphincter. As Buddy’s knot entered and stretched Becky’s asshole to new limits, the sudden turn of events was all Becky could handle and sent her over the edge, mentally. Her brain could not take this sudden onslaught of pain and pleasure any longer and had to shut down. Becky first lost control of her bladder, pissing all over herself, Buddy, and the floor, around the large faux cock still shoved up her cunt. Had her asshole not been packed so full of Buddy’s cock and knot, Becky surely would have shit herself too. Becky then lost the ability to hold on to the pillow in her mouth, dropping it, and screaming bloody murder, before finally blacking out. Buddy did not care if his bitch was alive or dead. All he cared about was the fact he had his cock buried in a hot, tight hole and now that he had knotted his bitch, he was in control and owned his bitch. Buddy continued pounding away at Becky’s lifeless ass, hard, fast, and as deep as he could with his knot now buried deep in Becky’s bowels. Despite Becky’s lose of consciousness, she continued to squirt her pussy juices and pee, all the while continuing to orgasm. After about 5 minutes of non-stop pounding by Buddy, and continuous orgasms and squirting, Becky started to come around. Becky slowly regained her senses and finally managed to regain her composure and was able to get herself up off of her face and back up on her hands and knees. This was the first time in Becky’s colorful sexual history that she had ever blacked out, at least without the help of a lot of alcohol. She knew this was an experience she would never forget and most likely would ever be able to, or should, repeat. Becky was now beginning to clear the fog out from her head and again starting to enjoy the pleasure that was befalling her. Becky again started enjoying being so royally fucked. She was stuffed so full, she thought she was going to explode. Buddy’s knot was now buried very deep into Becky’s bowels. She again began to moan "Holy shit, oh fuck I am so fucking full! Oh Buddy, you are a fucking God! You can fuck me any time you want! Oh my fucking God, I can’t stop fucking cumming. What the fuck have you done to me?" Becky continued crying out. Becky knew this incredible experience would soon be coming to an end. Becky could feel Buddy’s cock begin to throb and expand as he was getting ready to piss his spunk into Becky’s waiting bowels. Becky’s orgasms continued to hammer away at her body. Becky and Buddy had been fucking for over 25 minutes now, Becky continually squirting her pussy juices for most of that time. Between her pussy juices and her piss, Becky was kneeling in a small lake of her own body’s fluids. Buddy’s cock continuing to throb and expand, finally exploded, filling Becky’s bowels and stomach with what felt like gallons of cum. This again sent Becky’s orgasms into overdrive, causing her to shake and cry out in unintelligible moans. After a solid 15 minutes of shooting his sperm into Becky, Buddy had finally finished emptying the contents of his full balls in to her bowels and stomach and had turned around. Becky and Buddy were now tied together, ass against asshole. Between the cucumber, Buddy’s cock and knot, and a stomach stuffed full of spunk, Becky’s belly began to bulge out as if she was a few months pregnant. Becky had never felt so full in her life. Becky had cum so much, she could not even begin to count how many. Becky was dripping wet with sweat and shaking from what she had just experienced. After catching her breath, Becky reached back, grabbed her vegetable dildo, and pulled it out. This again caused Becky to cum, squirt, and piss, all at the same time. This was another first for Becky. It had now been just over an hour since Buddy had first penetrated Becky’s asshole. Buddy’s knot had finally shrunk enough for him to pull it out of Becky’s asshole. Buddy pulled out with a loud plop. Becky was so worn out, she was not able to clench down on her asshole to prevent a flood of dog spunk from pouring out of her asshole. Becky was so physically and mentally exhausted from that life altering double fucking, that she just collapsed into the pool of cum, pussy juices, and piss below her. The impact of Becky’s still distended belly, caused the shit covered spunk, still left in her bowels, to shoot out of her asshole, like a cannonball out of a cannon. Buddy immediately came over and began licking up the cum cocktail around and on Becky’s body and eventually worked his way to the cum splatterings on the front of the couch. Becky finally was able to gather the strength to get her self up off of the floor, staggered to the bathroom, walking as if she still had a Buddy’s baseball bat sized cock, still shoved up her ass, and got into the shower. As Becky soaped up her body, she was shocked to feel how wide open her asshole was still stretched. Becky easily shoved four fingers into her asshole with no resistance at all. Becky knew it would be a while before her body would recover from the fucking she had just received. On one hand she was worried she may have damaged her always tight body and holes. On the other hand, she was proud of what she had accomplished and how much she was able to cum, despite the fact she blacked out for 5 minutes. Becky’s only regret was that she did not have this experience on videotape, so she could relive this experience over and over again. Becky got out of the shower and dried off, but still did not bother to get dressed. Becky returned to the living room to clean up what was left of her mess. Fortunately, for her, Buddy had licked up most of the bodily fluids on the floor. Becky picked up her cucumber and oil and returned them to the kitchen. Becky washed off Mary’s cucumber and put it back in the refrigerator, laughing as she did. She could picture Mary eating it, not knowing where it had been. This thought alone began to make Becky horny again. She looked over at Buddy sleeping in the corner wondering if he would be able to go again any time soon. Then she thought to herself, he’s got the right idea and went into one of the boy’s bedrooms and climbed into bed, falling asleep almost before her head hit the pillow. Becky was awaken several hours later by a beam of sunlight hitting her in the eyes. Becky was surprised to see it was morning already. She was also disappointed that she did not get another chance to fuck Buddy before Mary woke up. She knew that Mary was an early riser and she would not have time to fuck Buddy the way she wanted to, as it usually ends up lasting more than an hour, by the time they become untied. Becky got up and went into the bathroom to pee. While in there, she tested her asshole and pussy to see how tight they were. As usual, her holes were good and tight. That was something Becky was proud of. She could fuck a tree trunk and still come back almost as tight as a virgin. Becky’s asshole was a little sore however. This was one of the ways she measured her success, if she could fuck something so big it made her sore, she knew she had fucked something bigger than she had ever fucked before. Becky decided if she did not have time to fuck Buddy, she would try something else. Becky, still naked, went in and crawled into bed with Mary. Becky started gently brushing the hair from Mary’s face, in an attempt to gently wake her. Mary woke up looking at Becky. "What are you still doing here? Mary asked. "Oh, I wanted to make sure you were okay," Becky replied "plus, someone needed to take care of Buddy too. How are you feeling?" "Okay, I guess, Mary answered. "What do you remember about last night?" Becky asked. Mary looked at Becky with a funny look. "I remember everything, thank you!" "Well," Becky said "you know I need to check you again." Before Mary could say a word, Becky covered Mary’s lips with her own. Mary was not sure how to react. She was not exactly comfortable with the thoughts of Becky finger fucking her to sleep the night before, and now this. Mary tried to push Becky away, saying "No Becky, we can’t do this again, this is wrong." but Becky pushed her hand away, reached under the covers, and slipped her hand into Mary’s panties. Mary turned her head and tried to squirm her way out of this situation, but Becky would not give up. Becky quickly found Mary’s clit and began to massage it. Mary slowly began to give up the fight and started letting Becky have her way. As Becky was massaging Mary’s clit, she gently stuck a finger into Mary’s tight pussy as she slipped her tongue into Mary’s mouth. It took several minutes of this before Mary finally gave in and let herself enjoy what was being done to her. After all, this is what she was really after, when she tried to fuck Buddy against the couch. Mary’s hips began to thrust against Becky’s fingers as they continued to penetrate her tight pussy. She also began sucking on Becky’s tongue and eventually managed to slip her tongue into Becky’s mouth. Once Becky felt Mary tongue in her mouth, she knew she had Mary right where she wanted her. Becky stopped kissing Mary just long enough to pull Mary’s nightshirt up and off. Becky went back to Mary’s mouth, while one hand continued fingering Mary’s clit, the other was now caressing Mary’s tits. Eventually Becky moved her mouth from Mary’s lips to sucking on her nipples. With Mary no longer having Becky’s tongue in her mouth, she was able to moan in ecstasy. After Becky had fingered Mary to 2 orgasms, Becky decided she needed a change. Becky slid down lower in the bed and started pulling Mary’s panties off. Becky continued finger fucking her older sister, but now had added a new stimulation. Instead of using her finger to stimulate Mary’s clit, Becky was now using her tongue. Becky slowly and methodically sucked and licked every inch of Mary’s cunt, eventually working her tongue down the crack of Mary’s ass and into her anus. Mary continued moaning. "Oh god that feels good! Becky we shouldn’t be doing this... Oh fuck that feels good! Oh yes, YES! Oh fuck yes! You’re going to make me cum!" Mary continued. "Oh, oh, oh, yes, yes, right there, don’t stop, oh fuck, I’m cumming!" Mary cried out. Becky had no intention of stopping, but she did stop long enough to reposition her body. Becky turned her body around, straddled Mary’s body, and placed her pussy right in Mary’s face. Mary had never been with a woman before and was not quite sure of what to do. Mary began lightly and slowly, licking at Becky’s cunt. "That’s it, just lick it." Becky said "Do what you think would feel good to you." Mary did the best she could, but was still unsure about this whole situation. Eventually Mary forgot about how wrong this was and started concentrating on how good it felt instead. Becky sucked Mary to yet another orgasm, but due to her inexperience, Mary was unable to return the favor. After about 15 more minutes of Mary and Becky’s 69 fucking session, and Becky being on top of Mary, pushing against Mary’s bladder, Mary had to make Becky stop. "I have not peed in at least 12 hours," Mary said "if you do not stop, I am going to pee all over you and the bed." "I have no problem with that." Becky said with a grin. Mary jumped up out of bed, still naked, and headed for the bathroom. "Okay, you go to the bathroom and get yourself cleaned up," Becky continued "and I will have a surprise for you when you come back." As Mary disappeared into the bathroom, she looked back at Becky, with a puzzled look on her face. While Mary was in the bathroom, Becky went out to the kitchen to get her cucumber and oil. As she looked at the cucumber, she knew it was going to be too large for Mary’s tight holes, at least to start with. Becky looked around to see if she could find anything smaller to loosen up Mary and get her started. As Becky was rummaging through the different shelves of the refrigerator, she opened one of the produce drawers and struck gold. Becky found exactly what she needed, a bag full of different sized, whole carrots. As Becky headed back to the bedroom, she looked over at Buddy, still sleeping in the corner, and whispered "you keep resting up big boy, if all goes well, you are going to have one hell of a great day." On the way down the hall, Becky stopped at the linen closet and grabbed a bunch of large towels. If all goes well, Becky thought to herself, things are going to get messy. When Becky returned to the bedroom, Mary was still in the bathroom. Becky decided she needed to hide her goodies until Mary got back into bed. Becky knew that Mary was still not completely comfortable with what was happening and if she saw the cucumber, carrots, and oil, it might scare her and she would not allow things to continue. "Are you alright in there?" Becky yelled into Mary. "Um, yeah, I’m okay, I’ll be out in a minute." Mary called back in a shaky voice. While Becky was lying on the bed waiting for Mary, she noticed a hard, black case lying on the floor in the back of Mary’s closet. Oh no, it can’t be? Yes, it is. This is going to be perfect, Becky thought to herself. Just as Becky had hoped, it was a video camera case. Please, let there be a tape in there, Becky said to herself. This must be my lucky day, Becky thought. Before Mary returned from the bathroom, Becky quickly set up the camera, finding the best possible angle for filming the bed. Becky covered the camera with clothes, hit the record button, and hid the remote control under some pillows. As messy as Mary kept her bedroom, Becky knew Mary would never notice another pile of clothes on the dresser. Becky jumped back onto the bed, just as she heard the bathroom door start to open. Mary returned from the bathroom wearing her bathrobe. "Why did you put your robe on," Becky asked "are you cold or something?" "We can’t be doing this." Mary began "I know it kind of feels good, but it is not right. We just can’t do this anymore." "Why?" Becky asked, "who are we hurting? Who says it’s wrong? Who’s going to know? Listen," Becky continued, "I know you are horny. I know you do not have time for a man. Why can’t I help you out? I know what feels good and how to make you feel good. All you have to do is let me do it and let yourself enjoy it. You know you want it. If you didn’t want to get laid so badly, you would have never tried to fuck a dog. Now take off that stupid robe and get your ass into this bed with me. Besides all of that, if you don’t, I am going to tell Mom and Dad and everyone else you know that you fucked your dog, twice." Becky said jokingly. Mary looked at Becky, not sure if Becky was serious or not about her threat, slowly took off her robe, timidly climbed into bed with Becky, and quickly wrapped herself up in the covers. "Oh please don’t tell anyone," Mary begged "I would die if anyone found out what happened to me, or what I tried to do." "What kind of sister do you think I am?" Becky replied. "Oh no," Mary said sarcastically "you want to molest me, but you would not rat me out, yeah right. Why are you doing this?" "With my wimpy ass husband working all the time," Becky began "he is always too tired to fuck. I’m lucky if he lays me once a month, so I decided I needed to come up with some alternatives. I’m too young and horny to only get laid once a month. I know, between the boys and your job, you don’t have time for a man, or to get laid. I have 12 hours to teach you what it took me almost 10 years to learn. If you will trust me and do what I tell you to do, I may not be able to make your life easier, but I can make it better. At least sexually. Can you honestly tell me you don’t want to get laid from time to time?" "Well, yeah, of course I do, but with a man, not my sister." Mary answered. "Let me tell you something," Becky snapped back "the first thing you need to learn is to take it wherever, whenever, and by whoever, is offering!" "Listen," Becky barked "it’s as simple as this, do you trust me or not?" "Of course I do." Mary replied. "Then shut up." Becky said softly, as she again began kissing Mary’s lips. This time, Mary was a little more receptive. Mary started kissing back as Becky slowly and lightly began caressing Mary’s breast. After a few minutes, Becky began getting more aggressive, sliding her tongue into Mary’s mouth while pinching her nipples to get them hard. "You have amazing nipples," Becky whispered "they are so big. I’ve never seen nipples as good as yours, I have to have those." Becky continued as she moved her mouth from Mary’s lips to her nipples. Mary was finally letting herself enjoy Becky’s treatment of her body, letting out a light moan as she slid her hand from her breast to her clit. Becky continued sucking Mary’s breasts, as she worked in one finger than another into her pussy as she used her thumb to keep stimulating her clit. Mary was lying on the bed, softly moaning, as Becky pleasured her body. Mary could feel her orgasm starting to build and Becky could sense Mary was getting close. Becky stopped what she was doing, just long enough to move lower on the bed, so she could start pleasuring her sister’s cunt with her tongue, as well as her fingers. Mary’s moans grew louder as her orgasm continued to build. Becky started teasing her sister by licking her inner thighs and outer pussy lips, in an effort to allow Mary’s orgasm to continue building. Becky slowly worked her way into Mary’s cunt, occasionally brushing her clit with her tongue. Becky continued increasing her pace in Mary’s cunt and started rubbing her clit again with her fingers. Mary was now completely consumed by the wonderful feelings her sister was providing for her. "Oh yes, oh god that feels good! Oh fuck, you’re gonna make me cum, oh god that feels good! Oh God don’t stop, don’t ever stop! Right there, right there, oh fuck, that’s the spot, don’t stop, oh God, please don’t stop, please, please don’t ever stop! Oh my fucking god, that feels so fucking good!" Mary was on the verge of a long awaited orgasm, and Becky knew it. Becky licked her finger and stuck it up Mary’s anus and stated stimulating her asshole. That drove Mary over the edge. "Oh, oh, oh God! Fuck, yes, yes, yes, oh God yes! I’m gonna cum, Fuck, I’m gonna cum! Oh God, that feels good! Yes, yes, yes, yes, oh fuck yes! I’m cumming, oh fuck I’m cumming!" Mary was now thrusting her hips at Becky’s face, yelling out as loud as she could. Becky was burying her tongue as deep as she could into Mary’s cunt, while rubbing and pitching her clit and thrusting her finger in and out of Mary’s ass as fast as she could. Becky was loving the fact that she was able to bring her sister to such a massive orgasm, as well as the taste of Mary’s juices as they pooled on her tongue and flowed down her throat. As Mary’s orgasm subsided, Becky began to slow her pace and pull her finger from Mary’s anus. "Oh, don’t stop." Mary whined. "Don’t worry baby, we’re just getting started," Becky replied softly. Becky then reached down beside the bed and brought up her cucumber, bag of carrots, bottle of olive oil, and towels. "What are you going to do with all that?" Mary questioned. "What do you think?" Becky answered. "You’re not going to stick that shit in me, are you?" Mary again asked. "Well, if you had some dildos, vibrators, and butt plugs, I wouldn’t need to use this stuff." "Wait!" Mary cried out. "That cucumber is too big! Please don’t put that thing in me!" "No, no," Becky replied, "we’ll start with the carrots and work our way up. Trust me, you’ll love it. By the time we get done, you’ll be begging me to fuck you with that cucumber." "Don’t bet on it," Mary said smartly. "Oh, we’ll see," Becky replied "we’ll see." Becky pushed Mary over on to her side, laid towels across the bed, and rolled Mary back on to her back. Next, Becky took the bottle of olive oil and began pouring it all over Mary’s body. "What are you doing?" Mary asked. "Trust me and hush," Becky replied, "unless you are screaming out in pleasure again, that is." Becky began to slowly massage the oil into Mary’s soft skin, working it into every nook and cranny. Mary closed her eyes and enjoyed the sensation. Becky then poured more oil down Mary’s pussy and ass. She started working the oil into Mary’s cunt and ass with her fingers. This alone had Mary’s next orgasm starting to build. Becky ripped open the bag of carrots, grabbed a small sized carrot, and began lubing it up with oil. Becky then took the carrot and started rubbing up and down the outer lips of Mary’s pussy, again teasing her in order to build up her next orgasm. Next, Becky started rubbing at Mary’s clit with the carrot, while grabbing a bigger carrot and lubing it up the same way. Becky then took the second carrot and started rubbing it against Mary’s pussy while still stimulating her clit with the other. Then, without warning, Becky shoved the larger of the 2 carrots into Mary’s cunt, large end first. "Oh God!" Mary jumped up and screamed. "What the fuck are you doing to me!" "Just relax and enjoy it." Becky replied. After Mary got over her initial shock, she again laid back and began to enjoy Becky impaling her with her faux dick carrot. Becky grabbed another carrot from the bag, lubed it up, and began teasing Mary’s ass. "Oh fuck no!" Mary yelled. "Please don’t stick that thing up my ass, it hurts too much." "Just be quiet," Becky barked back. "I swear, the next time you question me or try to stop me, I’m going to shove that cucumber, the whole bag of carrots, and that bottle of oil up your ass, only this time with no lube! If you going to learn from me, you have to trust me! Otherwise, I am going to leave right now and you can live the rest of your life like a nun! Now, what’s it gonna be?" "Okay, okay, I’m sorry. I’m just a little scared that’s all. Please don’t leave, don’t stop!" Mary begged. "I won’t say another word, I promise, just don’t stop!" Becky continued fucking Mary’s cunt with her carrot, while rotating teasing her asshole and clit with the other two carrots. Mary once again was enjoying this stimulation and moaning in pleasure. Then, without warning, Becky pushed the bigger of the two carrots into Mary’s ass. "Oh fuck!" Mary yelled. She wanted to tell Becky to stop, but knew Becky would follow through with her threats. Mary took a deep breath and tried to relax. Meanwhile, Becky continued to double fuck Mary with the carrots, while sucking on her clit. It only took a few minutes before Mary was thoroughly enjoying this double penetrating action. "Oh yes, oh fuck, oh God, oh God that feels so good! Oh God, make cum again, please make me cum again." Mary’s orgasm was building fast, but just as Mary was on the verge of her next major orgasm, Becky stopped what she was doing and quickly pulled out both faux cocks. "No, no, oh God, please don’t stop,!" Mary begged. "Please, please, put them back in, don’t stop, oh fuck I need to cum, please, please put them back in!" Becky just ignored her and started teasing her cunt again, this time with an even larger carrot. Becky continued teasing around Mary’s cunt until she calmed down. Becky again slowly started stroking at Mary’s pussy and clit, eventually penetrating her cunt with the larger carrot. Mary moaned out in a combination of pain and pleasure. Other than being raped by Buddy two days earlier, it is the biggest thing to be in her cunt in years. Once again, Becky was fucking Mary’s cunt with a carrot and stimulating her asshole and clit. Becky took a slightly larger carrot than before and again plunged it deep into Mary’s ass. "Oh God!" Mary yelled out. Mary’s orgasm was building fast. "Oh fuck that feels good. Fuck me, fuck me!" she continued calling out. Once again Becky was double fucking her older sister while munching away at her clit like corn on the cob. Becky could once again feel and hear Mary’s orgasm build. "Oh God yes, fuck me, eat me, oh God, please make me cum! Yes, oh God, I’m going to cum, yes, yes, oh fuck I’m gonna cum!" Once again Becky stopped just short of Mary’s orgasm. "No, no, fuck no, please, oh God no! Please, don’t stop! Put them back in, oh please put them back in! Fuck me, please fuck me! I need to cum, oh God, I have to cum!" Again, Becky ignored her cries. This time Becky climbed back up to the top of the bed and started kissing Mary’s lips. Mary was so overwhelmed with her need to cum, she practically attacked Becky’s tongue. Mary was no longer thinking of Becky as her little sister, but as a lover. This was beginning to really turn Becky on, making her even hornier. Becky stopped their kissing, turned her body around, and straddled Mary’s face, once again placing her pussy directly over Mary’s mouth. Mary immediately began eating at Becky’s cunt as if she had been doing it all her life. Mary drove her tongue as deep into Becky’s cunt as she could. Just the thought of being pleasured by her only sister, for the first time in her sister’s life was enough to bring on Becky’s unexpected orgasm. Becky’s juices were flowing into Mary’s mouth like water from a hose. Becky decided it was time to return the favor. While Mary continued eating out Becky’s pussy, Becky bent to go down on Mary. Both sisters were moaning in each other’s arms, while locked tight into a 69. While still eating out Mary’s cunt, Becky grabbed the largest carrot she could find. Becky once again began teasing Mary’s pussy and clit with the carrot before finally shocking Mary by ramming it up her ass as far as it would go. Becky knew it was much bigger than Mary was used to, but she knew Mary would take it. Mary stopped eating Becky’s cunt, just long enough to let out a low groan. "Holy shit, oh fuck yeah, oh shit, oh fuck that hurts! Oh fuck, it’s so fucking big!" The vibration of Mary’s groan sent a sensation through Becky’s cunt that caused her to orgasm immediately. Becky let out with a scream that even surprised her. "Oh fuck," Becky moaned, "you’re making me cum! God you’re getting good at this!" Becky started fucking Mary's ass with her carrot while she continued eating out her pussy and nibbling on her clit. Knowing that Mary could not see what she was doing, Becky grabbed the cucumber and started oiling it up. Becky then took the bottle of oil, placed the opening of the bottle into Mary’s cunt, and started pouring oil into it. Mary could feel herself getting very wet, very fast, but she was too preoccupied with other things to care. Before Mary had a chance to think about what Becky was doing, Becky grabbed the cucumber and rammed it inside Mary’s body. Mary let out with a blood-curdling scream that was muffled only by Becky’s torso, still sitting on Mary’s face. Mary began bucking and pushing at Becky’s body to get her off of her and pull those telephone poles out her ass and pussy, but Becky did not budge. After Mary started to settle down, Becky climbed off of Mary’s face, turned her body back around, and crawled back to the middle of the bed. Becky wanted to be able to see the look on Mary’s face as well as allow Mary to enjoy her upcoming orgasm, without any distractions. "Oh God, it’s too big, it’s too fucking big, take it out, oh my fucking God, please take it out!" Mary screamed. Becky started pulling out her improvised dildo, only to ram it right back into her sister’s delicate cunt, while at the same time plunging the carrot in and out of her asshole. Mary’s screams continued. "Oh God, you fucking bitch, oh my God, oh my fucking God! Oh fuck it’s big, they’re both too fucking big! Oh God Becky, I can’t take this, I feel like you are splitting me in half! Please, Becky, please, make it stop, oh God, oh fuck, make it fucking stop!" "Just relax," Becky said softly, "take a deep breath and give it a minute. Once you relax and allow your self to stretch, you will be begging me to never stop." "No, no, I can’t!" Mary cried. "Trust me baby, you can do it." Becky replied softly. To help Mary relax, Becky started caressing her breasts with oil, and pinching her nipples, while sucking on Mary’s clit, humming to help stimulate and vibrate Mary’s clit. Within minutes, Mary was singing a new tune. "Oh God, oh fuck yes! Fuck me, oh God, fuck me, make me cum!" Becky started to pick up the pace, fucking Mary harder and harder with her vegetable dildos. Mary was still bucking and thrashing, only this time in with pleasure instead of pain. "Oh my fucking God that feels good! Oh yes, oh yes, oh fuck, fuck me, fuck me, oh God, please fuck me! Your gonna make me cum! Oh fuck, please, please let me cum! Don’t stop, don’t pull them out, please let me cum, please, fucking let me cum! Please, please, let me cum! Oh fuck I need to cum!" Becky was indeed going to let her sister cum. After bringing her to the brink twice before, Becky knew Mary was in for an earth shattering orgasm. Probably, the biggest, baddest, most intense orgasm of her life. Mary was still bucking and screaming. Sweat was pouring off of her naked body. She had both fists clenched full of the bed sheets as Becky continued fucking her as hard, as deep, and as fast as she could. Mary was now humping back at Becky, trying to meet her thrust for thrust. Mary’s orgasm was now only seconds away. "Ooh, ooh, oh God, I’m gonna cum, I’m going to fucking cum!" Mary continued. Suddenly, Mary started panting like a dog. "Yes, yes, yes, oh fuck, oh shit, oh my fucking GOD I'M CUMMING!" Becky continued pumping at Mary’s holes with her vegetable dildos as fast as she could, all the while still sucking and biting Mary’s clit. Mary was now moaning and screaming unintelligibly. Her head was bucking up and down and side to side. Becky continued pumping her cucumber in and out of Mary’s cunt, while she had her lips wrapped around Mary’s clit and was humming to increase the stimulation in her clit. The combination of the different sensations made Mary’s orgasm even more intense. About half way through Mary’s orgasm, Becky started to slowly pull the carrot of Mary’s ass, while tapping on it for vibration. That was more than Mary could handle. Suddenly, just as Becky pulled the last of the carrot out of Mary’s asshole, Mary let out with a long, low, moan and started squirting pussy juices all over Becky’s face. Mary was not sure what was happening, but she was so overcome by her orgasm, that she didn’t really care. Mary continued cumming and squirting for what felt like hours. Becky was still fucking Mary with her cucumber and sucking on Mary’s clit, but was starting to slow down as Mary was coming down from her sexual high. After a couple more minutes, Mary’s orgasm was all but over. Becky slowed down and eventually stopped, pulling the cucumber out Mary’s swollen, red, pussy. Becky, her face still dripping with Mary’s cum, crawled up on the bed and cuddled close to Mary. "How are you feeling?" Becky asked. "Oh fuck," Mary said, "that was incredible, how did you do that?" "Lots of practice." Becky replied. "What happened?" Mary asked, "did I pee on your face?" "No," Becky answered, "you came so hard you squirted your cum all over me. Do you want to see how good you taste?" Before Mary had a chance to answer, Becky had covered Mary’s lips with her own and was sucking on Mary’s tongue. Becky and Mary continued making out for about 10 minutes, swapping tongues back and forth and caressing and squeezing each other’s tits. Becky finally pulled back. "Well," Becky began, "how was it?" "Oh God," Mary answered, "I have never felt anything like that in my life! That was awesome! How did you do that? Where did you learn how to do that? "Oh, I guess I just picked up." Becky answered. "Do you think you could do the same for me?" Becky asked as she pulled Mary’s hand between her legs. "Ugh, I, I don’t know, I, I guess I could try." Mary replied. "I don’t know if could do it like you did it, but I can try if you want me to. "As much as I would love for you to do that," Becky said, "today is about you, but you do owe me." Without Becky and Mary noticing, all of Mary’s moaning and screaming, along with the strong scent of perspiration and pussy juice caught the attention of Buddy. Buddy had sneaked into the bedroom, found a soft pile of clothes, and lay down to watch the action. As Becky got up to go get them something to drink, she noticed Buddy. "Well big boy, I see you have recovered nicely." Becky said to Buddy. "You’re a real horn dog aren’t you? You don’t miss a thing. Don’t worry," Becky continued, "I haven’t forgot about you. Your turn is coming real soon," Becky said, turning and smiling at Mary. Mary looked back at Becky with a suspicious and unsure look on her face. "What are you talking about?" Mary asked. "Just lay down, relax, and don’t worry about it," Becky answered, "you’ll find out soon enough." While Becky was in the kitchen, Mary lay in bed, her mind racing. Surely Becky is not going to make me fuck that damn dog, Mary thought. I won’t do it, I don’t care what she says or does, I will never do that again. Just then, Becky returned with a couple of glasses of wine. "Isn’t it a little early for wine?" Mary asked. "It’s Sunday," Becky replied "and we have a long day ahead of us, besides, you still need to relax a little more, I have big plans for you today." "If your plans include me fucking that damn dog," Mary barked, "you can just forget about it." "Oh, just don’t worry about it," Becky answered, "by the time this day is over, you will have a whole new outlook on things. Like I said earlier, you just have to trust me, now shut up and drink your wine." Mary and Becky laid in bed, continuing to make out, and caress each other’s body, while sipping their wine and resting up from their first incestuous session. "You don’t know how lucky you are to have a dog like Buddy." Becky began. "To start with, he is incredibly smart and learns fast. He also can be very gentle, when you tell him to be, not to mention the fact that he is hung like a fucking horse. If you will let me, I can teach you how to get the most out of owning a dog like Buddy. If you will let yourself, you can really make yourself very happy with Buddy." "I don’t want to do it." Mary started. "That fucking dog raped me twice and it hurt like fucking hell. I’m not going to give him a third shot at me." "First of all," Becky interrupted, "he only raped you once. You invited him the second time. It’s not his fault you were in the wrong position and he fucked your ass. He was just doing what you told him to do. Plus, while you were sleeping, I spent most of the night working with Buddy. I have taught him how not to be so rough, unless you want him to be." "Listen to me," Becky continued, "you have been bitching about being horny and not having time for a man for well over a year now. I am giving you a chance to make up for that. Believe it or not, you and I are in the same boat. Just because I am still married doesn’t mean I’m gettin’ laid all the time. With that wimp ass husband of mine working all the time, I’m lucky if he fucks me with his tiny little dick, once a month. I had to find other means to satisfy myself. My dog doesn’t have half the cock your dog does, so you might as well take advantage of it." "Yeah, I know," Mary started, "but he so big and it hurts so bad. I just don’t think I can do that again." "I told you Mary, I have been working with Buddy, and he will not hurt you." "What do you mean you’ve been working with Buddy?" Mary questioned. "Did you let him fuck you too?" "Of course," Becky boasted "how else was I supposed to show him what to do and what not to do. We fucked several times throughout the night and Buddy was incredible. I have cum more in the last 12 hours than I have cum in the last 12 months, thanks to your incredible dog. Now, if you will let me help you and teach you, you can have the same pleasures I have had in the past 12 hours for the next 12 years, but you will have to share him with me once in a while." Becky joked. Before Mary had a chance to answer, Becky kicked the covers off of her and Mary and called to Buddy. Without hesitation, Buddy jumped onto the bed and immediately stuck his nose in Becky’s crotch and began licking. Becky laid back and let Buddy eat her out. "Oh yeah, that’s it baby, oh yes, right there, right there, oh God don’t stop, oh God, your tongue is almost as good as your cock." Becky moaned. Mary was lying there half in shock that her sister was letting a dog eat out her cunt. At the same time, it was making her horny, and she could feel her own pussy starting to get wet. Becky could tell Mary was getting turned on and thought she should make Buddy stop and let him start eating out Mary, but Becky was enjoying Buddy too much. After all, Becky thought, I just got Mary off without her returning the favor. I deserve this, I need this. "Oh fuck!" Becky yelled. "Oh God that feels good, keep going Buddy, keep going! Oh yes, make me cum, make me cum you fucking beast! Yes, yes, oh God, I’m gonna cum, yes, yes, yes, oh fuck, I’m cumming, I’m cumming, oh fuck I’m cumming!" Mary just watched in awe. She was not sure what to make of what she was seeing. She was watching her baby sister allow a dog to eat her pussy until she had a screaming orgasm, all the while knowing it was wrong, but, at the same time, it was making her horny and making her pussy wet, very wet. While Becky lay on the bed, allowing Buddy to lick up her cum juice, she reached over and stuck a couple of fingers into Mary’s cunt. "I see you enjoyed that." Becky said. Becky then pulled her wet fingers out of Mary’s cunt and pushed them down to Buddy’s nose. Buddy stopped licking at Becky’s pussy and went straight for her fingers, still covered in Mary’s juices. Becky slowly pulled her hand back, leading Buddy straight to Mary’s crotch. Buddy instantly knew what to do and started licking Mary’s pussy. "Oh my God!" Mary gasped. "It’s okay," Becky whispered, "just relax and enjoy it. He is not going to hurt you, unless you consider an awesome orgasm pain, or you want him to hurt you." Becky laid back and sipped on her wine while Buddy continued licking out Mary’s cunt. Mary was still a little apprehensive, but she was slowly allowing herself to relax and enjoy this oral pleasuring. Mary had never really been pleasured orally before. Her ex-husband tried it a few times, but he was more into his own pleasure and never took the time to really pleasure her. A minute or two is all he would spend before moving on to his own pleasure. These thoughts were quickly erased from Mary’s mind as Buddy inched his tongue deeper and deeper into Mary’s folds, his nose and teeth now starting to rub against her clit. Mary had now reached full acceptance and was feeling her orgasm start to build. "Oh yes, oh God that feels good, oh yes, oh yes, oh, oh, oh fuck!" Mary moaned. Mary was slowly humping her hips towards Buddy, trying to force Buddy’s tongue deeper into her cunt. At the same time she was also squeezing her tits and pulling at her nipples. Mary’s moans continued. "Oh yes, oh God, what are you doing to me, oh God that feels so good, oh fuck you’re gonna make me cum, oh God please make cum, please, please God let me cum!" As Mary’s climax was building, Becky leaned over and started licking and nibbling at Mary’s neck and shoulders, slowly working her way down to Mary’s tits, until she was finally sucking Mary’s nipples while rubbing and caressing both of her breasts. The combined stimulation was quickly pushing Mary to the brink of her orgasm. Now Mary had gone from a low moan to a loud yell. "Oh yes, oh fuck, oh fuck, eat me, make me cum, oh fuck I’m gonna cum, I’m gonna cum." Becky started to lightly bite Mary’s nipples. That was all Mary needed to push her over the edge. "Ooh FUCK! I’m gonna cum, yes, yes, oh fuck yes, I’m, I’m cumming, I’m cumming, ooh fuck I’m cumming! Oh God, oh God, yes, yes, yes, oh fuck, oh God, oh yes, yes, oh fuck, oh, oh, oh, ooh! Oh my God, that was incredible!" Once Mary was able to catch her breath again, she turned to Becky and asked, "Will he do that to me anytime I want?" "If you want him to." Becky answered. "Oh fuck, he can do that to me any time he wants." Mary stated. "Good," Becky responded, "I’m glad you enjoyed it. But now, you need to take care of him." "What?" Mary questioned. "You don’t think that makes Buddy horny too?" Becky answered. "Look at him," Becky continued, "his cock is starting to push out of his sheath. He’s no dummy, he knows what a pussy is for. It’s all the same to him whether it is a human pussy or a dog pussy, he knows what it’s for, and what to do with it. You have to be able to give as good as you get." "Do I have to give him a blowjob?" Mary asked quietly. "Well," Becky answered, "you don’t have to, but you really should learn how to do it." "Oh," Mary responded "I have already done that. Before he raped my ass, I sucked on his cock to start getting him hard." "Yeah, but did you let him cum in your mouth?" Becky asked? "No way, Mary jumped back "I don’t want that nasty shit in my mouth!" "I think if you give it a chance, you will learn to really love it." Becky responded. "I’ll tell you what," Becky continued, "seeing as we are getting short on time, we can save that for later, if we have time before the boys get home. We have plenty of other things we still need to teach you." "Why do I have to do more? I am perfectly happy just letting him eat me every once in a while." Mary stated. "I don’t think so." Becky replied. "You know as well as I do, having your pussy eaten can only take you so far. Don’t you want to have a live cock in you every once in a while? You know that a cock feels better than a tongue. Sure his tongue feels great, but once you’ve had his cock, and enjoyed it, his tongue will never do as good of a job as his cock." "I’ve had his cock, remember." Mary said sarcastically. "It did not feel better than his tongue!" "That’s because you didn’t know what you were doing." Becky argued. "That’s why I have been training Buddy all fucking night, and now I’m going to train you. So stop arguing with me! We are wasting time. Now get your ass out of that bed and let’s go out to the living room." Mary started to say something back to Becky, but after seeing the look on her sister’s face, Mary took a deep breath, got out of bed, and headed to the living room. Buddy jumped off the bed and ran past Mary and Becky to the living room. Buddy knew what was about to happen. Becky escorted Mary to the couch. "First," Becky began "I am going to teach you a kind of starter position. This will allow you to have more control over Buddy’s pace, how deep you want to take him, and whether or not you want to take his knot. The first thing you need to do is slide your ass to the end of the couch and spread your legs." Mary did as she was told. Buddy did what he had always done with Becky and started licking at Mary’s pussy once again. "That’s a good boy." Becky continued. "You just let him lick you for a few minutes to make sure you are good and wet. In order to save some time, I am going to help Buddy’s cock start to get hard." While Mary sat on the couch, letting Buddy lick her cunt, closing her eyes and enjoying it, Becky got down on the floor, as if she was going to crawl under Buddy, and start sucking on his cock. Instead, Becky quickly and quietly returned to the bedroom to get the video camera. She returned to the living room and quickly scouted a place to hide the camera, where Mary could not see it, but in a good enough position to catch all of the action. Becky spotted a pile of magazines, comic books, and toys on one of the end tables and camouflaged the camera behind the toys and under the magazines. Becky’s movie would continue. Becky then got down on the floor, crawled under Buddy and began sucking his cock. Within minutes Buddy's cock was out of its sheath and hard enough to get him started fucking Mary. Becky crawled back out from under Buddy and sat up against the couch next to Mary and Buddy. "Okay," Becky said "now you need to slap your thighs to let Buddy know you are ready and he will put his front paws up on the couch." Mary did as she was told and Buddy responded just as Becky said he would. "Now take his cock," Becky continued, "and start rubbing it up and down against your slit to make sure you are both good and wet. Next you need to line up his cock with your pussy. Now you need to wrap your legs around his back end and start pulling him into you at your own pace. If Buddy starts to get too ambitious, all you need to do is tell him no and squeeze your legs a little tighter around his hind quarters." Mary continued to do as she was told. She slowly started to pull Buddy into her, taking him in slowly, one inch at a time. "Ooh fuck!" Mary moaned. Buddy began to slowly hump against Mary, helping to bury his cock a little deeper with each stroke. Mary continued to go slow with Buddy. It took over 10 minutes before Mary was able to accept the entire length of Buddy’s, over 14 inch, cock. Buddy’s cock was exploring depths of Mary’s cunt that had never been used before and Mary was beginning to enjoy it. "Oh fuck!" Mary continued to moan. "Oh fuck, he is so fucking big!" "Oh you son of a bitch, what are you doing to me, I am so fucking full! Oh God I’m full! Oh fuck, yes, oh fuck yeah, oh shit, Goddamn, I m so fucking full! Fuck that feels so fucking good, oh God that feels so good!" Mary started to quicken her pace against Buddy and Buddy returned in kind. Slowly, together they were starting to get up to a good speed. Mary was starting to sweat and every once in a while Buddy would lean down and lick the sweat from her body. That seemed to drive Mary wild. That gave Becky an idea. Becky went to the kitchen got a jar jam from the refrigerator. When she returned to the couch, she put a dab on her finger to let Buddy lick it. Buddy licked it like a wild man. Becky then spread some jam on each of Mary’s nipples. Buddy began licking at it, almost as if he was nursing. That sent Mary right over the edge. Mary quickly started increasing her pace against Buddy and Buddy met her with every stroke. Mary’s orgasms were starting to crash down on her. "Oh God, Yes!" Mary began to yell out. "Oh fuck, yes, fuck me, fuck me Buddy, oh god, fuck me good!" By now, without even realizing it, Mary had completely loosened her grip of Buddy’s hindquarters and they were both fucking each other at a solid, but not too hard, pace. "Ooh, ooh, ooh, ooh, ooh, fuck, fuck yes, oh fuck me, fuck me!" Mary continued. "Oh god Buddy, you are so fucking big, oh God you feel so good, oh fuck! Lick it, that’s it like my titties, suck Mommy’s titties, fuck Mommy and suck her titties, oh fuck you are so fucking good! Oh, yes, oh fuck yes, that’s it, make Mommy cum again! Ooh fuck, yes, yes, yes, oh fuck yes, I’m cumming, oh fuck I’m cumming!" Becky continued watching and enjoying the site of her sister getting her brains fuck out by a dog. She too was getting horny and her pussy was dripping with cunt juice, but for now, this was her sister's time, so she sat and watched as she played with her own pussy in an effort to get a little relief. Becky thought about getting her cucumber from the bedroom, but she decided she want to be able to concentrate on her sister getting fucked instead. Becky noticed Buddy’s knot was beginning to grow. It would not be long before his knot would be knocking on the door of Mary’s cunt. The question was going to be would Mary let him in and would Buddy be able to get it in that position? Meanwhile, Mary and Buddy were still fucking each other at a strong pace. Not as fast or as hard as Becky liked it, but that was something Mary would have to decide on her own when the time was right. Mary seemed to be enjoying it none the less. "Oh, oh, ugh, ugh, ugh, oh, fuck, oh shit! Oh yeah! That’s it! Don’t stop, oh fuck, oh god yes! Yes, yes! Oh god you’re gonna make me cum again, oh God, make me cum, make me cum, oh shit, oh God, fuck yes, yes, oh fuck yes, oh God I’m cumming, I’m cumming, ooh, ooh, oh fuck I’m cumming! Oh God, I’m cumming! Shit this is fucking good!" After yet another mind-blowing orgasm, Mary could feel Buddy’s knot starting to push up against her pussy lips. Mary was unsure and a little nervous about what to do next. She remembered the extreme pain cause by Buddy’s knot when he raped her, but at the same time, this experience felt nothing like her earlier experience. She was enjoying it this time. "What do I do now?" Mary asked as Buddy continued fucking her. "Well," Becky answered, "if you do not want to take the knot, than you are going to need to hold him back with your legs. If you want to take in his knot, you are not exactly in the best position to do it, but I think it can be done if you slide you ass down towards Buddy a little more and help push him in with your legs. Or, you could change positions by getting on the floor and letting him do you doggie style." Mary thought about it for a minute. Her nervousness was slowly being over taken by her pleasure and her lust for more was clouding her judgement. Buddy’s licking of Mary’s breasts was driving Mary wild. She quickly decided she definitely wanted to stay in that position. As for taking the knot, she was still unsure and the overwhelming sensation of another orgasm was not allowing her to think about it. With Mary now deep in the throws of yet another orgasm, and without realizing it she had made her decision. As Mary bucked against Buddy, ever harder and faster, the sweating of her body on a leather couch made her ass slide down more towards Buddy. That was all Buddy needed to knot his bitch in this unusual and awkward position for him. Buddy’s thrusts were steadily increasing as he was trying to knot Mary. Mary did not seem to mind the increase in pace from Buddy until she felt his knot starting to spread her pussy lips even farther apart. "Oh, God Buddy, no, please no!" Mary cried out. "I don’t think I can do this! Oh fuck it’s so big, oh God it’s big! Ugh, ugh, oh God it hurts, oh fuck, oh God, oh my fucking God! Oh God it big, oh yes, oh fuck, oh God yes, fuck me, fuck me harder! Oh God yes, bury that fucking knot in your Mommy’s cunt! Oh shit, oh fuck, oh, oh, oh God yes! Push it baby, push that fucking knot into your Mommy fucking cunt, oh God that feels good, fuck! Ooh yes, oh fuck yeah, oh God it’s in me, your fucking knot is in me!" Now that Buddy’s knot was buried deep in to Mary’s cunt, Buddy’s thrusts were much shorter, but still as intense. Becky was now sitting on the couch beside Mary with her feet up on the couch, she was facing Mary’s side with her toes almost digging in to the side of Mary’s hip. Watching her sister cum over and over again, plus seeing her take Buddy’s knot, was making Becky so hot and wet that she had to start finger fucking herself and rubbing her clit. With in seconds, Becky was having her own orgasm, squirting her pussy juices right on to Mary’s chest. This gave Buddy yet another thing to lick off of Mary’s tits and chest. That again drove Mary straight into another screaming orgasm. Mary had lost count of how many orgasms she has had so far, but she knew it was much more than she has had in years. They were also more intense than she had ever had in her life. Mary could feel Buddy’s cock begin to pulsate and his knot continue to grow. "Oh fuck!" Mary yelled, "it feels like he getting fucking bigger! Oh shit, oh fuck he’s getting bigger! Oh God, oh God that feels so good, oh God, yes!" Suddenly, Buddy started shooting his first load of cum. "Oh shit." Mary yelped. "Oh God, I am so fucking wet! It feels like somebody is blasting my insides with fire hose! Oh God, that is so hot, oh fuck that feels good, yes, oh God yes! That’s it boy, fill your Mommy full of your cum! Oh God yes, your gonna make me cum again, oh fuck! Yes, yes, oh fuck, oh yes, oh God, that’s it, don’t stop, oh fuck that feels good! Oh you son of a bitch, your making me cum, oh God, oh shit, oh yes, oh God yes! Oh fuck, I feel like I’m about to fucking explode, oh fuck, oh fuck yeah, oh fuck it feels good!" Buddy came for over 15 minutes, filling Mary’s womb full of his hot cum. Now Mary and Buddy were tied. When Buddy finally finished emptying his balls into Mary’s cunt, he wanted to turn himself around, as dogs do after sex. But, because of the position they were in, Buddy was not able to do that. In order to keep the action going and to get Buddy’s mind off trying to turn around, Becky again spread jam over Mary’s chest, tits, and nipples. This seemed to make them both happy and combination of the fullness of Mary’s womb and Buddy licking and biting at her nipples, allowed Mary to have a couple orgasms before the two would be separated. After about 25 minutes, Becky could see that Buddy’s knot had shrunk almost enough to pull out of Mary’s still tight pussy. "When he pulls out of you," Becky told Mary "I want you to bear down on your pussy and to try to keep as much of his cum inside of you as you can." Mary was not sure why, but Mary knew she need to try to do as she was told. After about another 5 minutes or so, Buddy was finally able to pull free of Mary’s gripping pussy. As Buddy pulled out, some of his cum was starting to escape, but Mary quickly tried to tighten her pussy muscles to hold it all in. Buddy immediately started licking and cleaning up Mary’s pussy. "Normally," Becky started "you could let it all flow out, if you wanted to, and Buddy would clean you up, but this time, I want to do it." Becky jumped down to the floor, pushed Buddy out of the way, and started licking Mary’s cunt and sucking on her clit. Becky was drilling her tongue into Mary’s tightly squeezed pussy licking up and drinking this cocktail of Buddy’s and Mary’s cum. Mary was slowly easing up on her pussy, allowing more and more cum to flow into Becky’s mouth. Once Becky had a good mouthful of cum, she crawled up to Mary’s face and began kissing her and forcing their cum into Mary’s mouth. At first Mary was repulsed and tried to resist, but eventually, Mary’s continuing lust and pleasure overruled her concerns and she began to accept more and more of their cum in her mouth. Becky would also take mouthfuls of cum and start sucking on Mary’s tits, spreading the still warm cum all over her chest and then licking it back off. While Becky would be up sucking on Mary’s tits or filling Mary’s mouth with cum, Buddy would sneak back to Mary’s pussy and continue to clean her, inside and out. After about 15 or 20 minutes, Mary’s cunt had finally run out of cum, but Mary was still a sticky mess, covered in cum. Buddy again jumped up on the couch and was helping Becky lick of the remaining cum from Mary’s body. Once they were done, Becky asked, "Well, how was it?" "Oh God," Mary stated, "that was incredible! I have never been fucked like that before in my life. And I have never been so full of cock and cum in my life either." "Good," Becky replied, "it will feel even better when we do it again a little later on, only this time, we are going to try a better position." Mary was both happy and concerned at the same time. She was not exactly sure what Becky meant, but she was happy about the fact that she would get fucked again later that day. "Why don’t we go take a shower and get cleaned up while we let Buddy recover? He is going to need to rest up before he is ready to go again. Why don’t you go and start the water?" Becky said. "I will be right behind you." As Mary walked to the bathroom, cum still dripping from her cunt and juices flowing down her legs, Becky went and turned off the camera. She wanted to take it into the shower with them, but she knew that would never work. So instead, Becky hid the camera in the bedroom again and hid the remote control under a pillow, so she could get to when they were ready to begin their next session. By the time Becky got to the bathroom, Mary was already in the shower. Becky slid the door open and joined Mary. Becky immediately put her hand out and crabbed Mary’s crotch. "So, how ya feelin’ down there?" Becky asked. "Oh fuck," Mary began to answer "I haven’t been so full or stretched so wide since I gave birth, but fuck that was good!" "I told you if you would trust me and take a chance you would be glad you did." Becky responded. "A few more good fucks and you’ll be an old pro at this. Now all we got to do is loosen up that ass of yours and you’ll really be set." "Oh no," Mary insisted "I don’t want that beast in my ass ever again!" "Yeah, yeah," Becky replied "just a few hours ago you were saying the same thing about your cunt, and now look at you. You look like you are ready to start fucking the doorknob. You just relax and leave it to me, have I done anything to hurt you yet?" Becky was definitely right about one thing, after being fucked better than she had ever been in her life, Mary was horny as hell. After Mary had finished rinsing the soap from her body, she turned to Becky and asked her, "How about I pay you back for the one I owe from earlier?" With that, Mary got down on her knees and started licking away at Becky’s cunt. This move really surprised Becky, as all along, Becky has been the aggressor. This time, Mary became the aggressor. Mary started munching away at Becky’s hairless pussy like she had been doing it all her life. She immediately started sucking and nibbling away at her clit, while burying her tongue deep in the folds of Becky’s sweet hole. Becky leaned back against the wall of the shower for support as she spread her legs wider, placing one of her legs on the side of the bathtub, to make it easier for Mary’s tongue to gain access to her cunt. "Ooh, ooh, ooh," Becky moaned "Oh fuck that feels good, oh Mary, fuck, you do that good, have you been holding out on me?" Mary did not bother to answer, but kept driving her tongue deeper and deeper into Becky’s cunt. "Oh shit!" Becky continued to moan. "Oh fuck, oh yes, right there, oh yes, oh fuck that’s good, yes, yes, right there, right there, that’s it, don’t stop, oh fuck don’t stop, oh fuck yes! Oh fuck yes, you’re gonna make your little sister cum, oh yes, make me fucking cum!" Becky started breathing deeply, hard and fast, she was on the verge of an orgasm. Suddenly, Mary stopped and pulled back. "What the fuck are you doing?" Becky yelled. "Now you see how it feels." Mary replied sarcastically. "You bitch!" Becky yelled back at Mary. "You get down there and finish what you started or I will shove that cucumber up your ass, followed by my fist!" Mary just smiled and rolled her eyes. "If you don’t think I’m serious," Becky yelled, "you just wait here and I’ll be right back." As Becky put her hand on the door to open it. Mary grabbed it and said, "Now who needs to relax? I planned on finishing you off, I just wanted to make you suffer for a minute or so." With that, Mary went back to sucking her sister’s pussy. While Mary was busy eating out Becky’s pussy, Becky grabbed Mary’s hand and began pushing one of Mary’s fingers into her asshole. Mary, a little surprised at first, realized, by Becky’s heavy breathing and moaning, this was enhancing Becky’s pleasure and began to finger fuck Becky’s ass without any help from Becky. Mary started with just one finger and eventually worked her way up to 2 fingers, and then, finally, 3 fingers. Becky was now leaning, with her back against the wall, playing with and sucking on her own tits, moaning while Mary sucked away at her cunt and finger fucked her asshole. "Oh fuck, oh fuck that feels good! That’s it, oh yes, that’s it, fuck me harder, fuck me deeper! Oh fuck, you’re gonna make me cum! Oh yes, that’s it, that’s the way to do it! Holy shit, you are so fucking good, oh yes, I’m gonna cum, oh fuck I’m gonna cum!" Within seconds, Becky had begun to cum. "Yes, yes, ooh shit, ooh, ooh, yes, fuck, oh fuck I’m cumming, oh shit that feels good, oh yes, ooh, ooh, ooh, oh fuck yes, yes, yes, yes, YES!! Oh fuck YES!" As Becky was cumming, Mary continued shoving her fingers in and out of Becky’s ass as fast as she could. Between Mary’s tongue and having 3 fingers plunged in and out of her asshole, Becky finally exploded in orgasm, squirting her pussy juices all over Mary’s face. Mary did not seem to mind, she just kept sucking and finger fucking Becky until Becky had reached the end of her orgasm. "How was I?" Mary asked as she returned to her feet. "You were fucking incredible." Becky answered. "Are you sure you’ve never done that before?" Mary just shook her head. "I guess being horny really brings out the best in you." Becky responded. After washing up for a second time, Mary and Becky got out of the shower and returned to Mary’s bedroom and lay down on the bed. "You and Buddy are wearing me out." Becky said to Mary. "The same goes for me." Mary replied. Together they decided to take a little rest before continuing with the rest of the day’s activities. Mary immediately fell asleep. Becky was fighting her urge to go to sleep because she was afraid they would sleep the rest of the day away and they would not have any time left to fuck each other or Buddy before the boys returned home. After Becky was sure Mary was asleep, Becky got up, removed the video tape from the camera, and sneaked out to the living room to see what kind of action she was able to catch. After watching her tape for about 45 minutes, Becky’s pussy was dripping wet and she was ready for some more action. As much as she wanted to, Becky did not allow herself to get off. She wanted to save it for her next session with Mary or Buddy. Becky set the tape where it had ended, tip-toed back to the bedroom, put the tape back into the camera, made sure she still had a good angle, and pressed the record button. Becky was ready to wake Mary up for some more action. Becky returned to the bed, crawled between Mary’s legs, started sucking at her pussy and clit, while massaging Mary’s rosebud with her finger. Mary began to wake up with a smile on her face. Becky stopped eating Mary’s pussy just long enough to ask, "How was your nap?" "Not as good as being woken up." Mary responded. Becky continued munching away at Mary’s cunt and started pushing her first finger into Mary’s anus. "Damn you’ve got a tight ass." Becky said to Mary. "We’ve got to get this thing loosened up, so you can more than just use it to shit with." With that, Becky quickly inserted a second finger. "Ooh!" Mary moaned. "Please take it easy on me," Mary continued, "I am still sore from yesterday." "Don’t worry," Becky answered, "just relax. Have I hurt you yet?" Becky continued sucking Mary’s cunt as she work a third finger into Mary’s, still almost virgin tight, asshole. After about 5 minutes of finger fucking Mary’s ass, Becky reached for her bag of carrots, oil, and towels. This time, Becky took the biggest carrot she could find and lubed it up with the olive oil. Next, Becky placed the bottle’s opening to Mary’s asshole, removed her fingers, and quickly shoved the neck of the bottle into Mary’s asshole before it could snap shut. "Oh shit!" Mary yelled, as she felt the cold glass intruder in her asshole. Becky tilted the bottom of the bottle up into the air, allowing the olive oil to flow into Mary’s asshole. Once Becky felt as if she had poured enough oil into her sister’s rectum, she removed the bottle and stuck her thumb in Mary’s ass to keep the oil from pouring back out. Next, Becky removed her thumb and took the fat end of the biggest carrot she could find and pressed it against Mary’s rear entrance. By force of habit, Mary bore down and tightened her asshole as much as possible. Becky began forcing the large end of the carrot against Mary’s asshole until it finally gave way and allowed the carrot to enter. "Ugh!" Mary groaned "Oh fuck, oh fuck that’s big! Please, please don’t do this, oh please Becky, I’ll do anything, just please don’t do this! Please don’t put that thing in my ass!" Becky ignored Mary’s pleas and continued pushing that large carrot deeper and deeper into Mary’s ass. "Oh fuck!" Mary yelped, "Not so fast, at least let me get used to it a little at a time! Oh fuck, oh fuck stop! Please, no, oh God please no, it’s too big, oh God it’s so big! Please don’t, it’s going in too deep, and it’s so fucking big! Oh God, please stop, oh God make it stop! Fuck, please make it stop, oh fuck!" To try and help Mary relax, Becky started to once again suck on Mary’s pussy and clit. She concentrated mainly on stimulating her clit. Becky knew that once Mary could feel her orgasm start to build, she would begin to relax and allow the carrot all the way inside of her ass. With at least 6 inches of carrot still sticking out of Mary’s asshole, Becky also started flicking, thumping, and tapping on the carrot, causing it to vibrate in Mary’s sensitive little ass. Within minutes, Mary’s moans of pain were becoming moans of pleasure. Becky decided, before burying the carrot deeper into Mary’s ass, she would bring Mary to orgasm. This, Becky thought, would make it easier on both of them. Becky continued nibbling and sucking on Mary’s clit, while she finger fucked Mary’s pussy, and continued using the carrot in her ass as a vibrator. Mary started moaning as her orgasm started taking over her body. "Ooh, ooh, ooh, yes, yes, oh fuck, oh fuck yes! Make me cum, oh fuck, make me fucking cum, oh God yes, fuck me baby, fuck me, oh fuck I’m cumming!" While Mary was dissolved in her orgasm, Becky pushed the large carrot deeper in Mary’s ass. By the time Mary had regained her senses, Becky had buried the entire 13-inch carrot, deep into Mary’s bowels. "Oh God," Mary moaned, "what are you doing to me?" Becky just ignored her sister and continued working on pleasuring her sister. Meanwhile, all of Mary’s screaming and moaning woke up Buddy. As usual, Buddy had to go check out what was going on. With all of Mary’s thrashing around, Becky had ended up with her upper body on the bed and her lower body kneeling on the floor. When Buddy came in the room and saw the position Becky was in, he immediately went over to Becky and started licking at her wet pussy, working his way up to her asshole. With Becky so preoccupied with Mary, she did not notice Buddy enter the room and was startled when she first felt his wet nose in her cunt. Once she realized what was happening, Becky spread her legs further apart to give Buddy more access to her cunt and asshole, while she continued working on loosening up Mary’s tight little ass. While Buddy continued lapping away at Becky’s cunt and ass, Becky continued her work on Mary. Becky grabbed two more large carrots from the bag. What are you going to do with those, Mary asked in a scared tone? Becky handed the first one to Mary. "Play with yourself with this one.! Becky ordered. "What do you mean?" Mary asked. "Just what I said, play with yourself!" Becky barked back "Fuck yourself with it, play with your clit with it, deep throat it, do what ever you want to do to get yourself off." "There are plenty more carrots left if you need more." Becky added. Becky took a couple more carrots and put them beside Mary so she could easily reach them if she wanted them. Although Becky was not paying much attention to him, Buddy was still eating out her cunt. By this time, Buddy has worked his tongue deep into Becky’s slit and was drinking up all of her juices he could find. While Mary started to gently fuck her own cunt with one carrot, she started rubbing her clit with another. Meanwhile, Becky started oiling up another large carrot. This time, Becky lined up the smaller end of the carrot with Mary’s already stuffed asshole. Slowly, but firmly, Becky started pushing the second carrot into Mary’s asshole. Again, Mary began to protest. "Oh fuck, what are you doing? I can’t take another one up there! Please stop, it hurts, oh fuck Becky, you’re hurting me! Why are you doing this to me?" "Just take a deep breath, try to relax, and keep playing with yourself." Becky answered. "If we can get that cucumber up your ass without too much of a problem, then you will be ready to get fucked in the ass by Buddy." "I don’t want that cucumber up my ass and I’m sure as hell not going to let that fucking dog fuck my ass again!" Mary shouted. "You said the same thing about your pussy a few hours ago and now look at you. You’re fucking yourself with carrots, you’re so damn horny. Relax and trust me. I’ve been where you are now, trust me, you’ll be thanking me later." "Don’t hold your breath!" Mary snapped back. Becky continued pushing her carrot deeper and deeper into Mary’s ass until she had finally come to the last three inches, the fattest part of the carrot. This would be the hardest and the most painful time for Mary, getting her sphincter stretched enough to allow the carrot to penetrate and still hold her sphincter open. As the pain increased, so did Mary’s tempo with her carrots, one in her cunt, being buried deeper and deeper with every stroke, and the other, stimulating her clitoris. Mary’s moans were a combination of pleasure and pain. "Ooh, oh God, oh fuck that hurts, oh fuck, oh God I need to cum! Oh fuck that feels good, oh fuck that hurts, oh fuck, stop, stop, oh please stop, your ripping me to pieces, oh fuck, oh fuck, oh shit you’re fucking tearing me apart!" The tightness of Mary’s asshole along, with the size of both carrots, and Mary still trying to resist, made it harder for Becky to advance the carrot deeper into Mary’s ass. Becky repositioned herself to get a better angle and more leverage against Mary’s ever expanding asshole. Millimeter by millimeter, Becky continued gently pushing the second carrot into Mary’s ass, tapping and thumping on it to increase Mary’s stimulation. Becky continued to push as Mary’s sphincter stretched more and more. Becky was so engrossed with the task at hand, she did not even notice Buddy’s paws on both side of her until she felt something hard poking at her ass cheeks. Before Becky could react, Buddy found a place to bury his cock. It was Becky’s asshole. The surprise, shock, and sudden pain caused Becky to jump and scream. The shock of Buddy burying his enormous cock in Becky’s ass, also caused Becky to shove the last few inches, mercilessly into Mary’s ass, causing Mary to also scream out in pain. "Oh you dirty little bastard!" Becky yelled. "Oh fuck, holy shit!" With one gigantic lunge, Buddy had buried his entire fourteen plus inch cock deep into Becky’s bowels, while Mary was still screaming out in pain as well. "Oh God, please stop, take it out, take it out, oh fuck, please take it out! I can’t do this anymore, you have to stop, oh God please, please make it stop!" Becky was getting it from both ends. Buddy was fucking her like a bullet train and Mary was kicking her legs, and thrashing her body all over the bed. With Becky’s asshole still sore from her double fucking the night before, it took much longer than usual for Becky’s asshole to get used to being packed so full and sphincter stretched so far open. "Oh fuck, oh shit, oh you son of a bitch." Becky moaned. She tried to muffle her pain, so her sister would not realize the pain she too was in by having something shoved up her ass unexpectedly. Becky managed to hold Mary down so she did not pull the carrots out of her ass. Mary had completely stopped fucking herself and had both hands clinched tightly around the towels and sheets on the bed. Becky was holding tightly to Mary’s legs to keep from being kicked, it also help alleviate some of her own pain. Becky’s pain seemed to begin to ease much quicker than Mary’s, most likely because Becky was used to, and very much enjoyed, get reamed up the ass. Mary on the other hand continued begging Becky to pull those carrots from her ass. "Oh fuck Becky, please take them out, I’ll do anything, just please, please take those fucking things out of my ass!" Mary continued screaming. "Keep playing with your cunt," Becky ordered, "once you allow yourself to relax and stretch, you will be okay." As Mary once again started to half-heartedly fuck herself, she could feel her body slowly starting to relax. Mary again started to increase her strokes and found that Becky was right. She could actually feel an orgasm starting to build. Becky too was starting to feel an orgasm build. Becky was now paying more attention to her own situation and less to her sister. "Oh yes, you fucking beast, fuck me good you son of bitch, fuck me good! Oh God that feels good, fuck me you son of a bitch, keep fucking me! Oh yes, harder, fuck me harder, yes, yes, that’s it, fuck me harder, fuck me deeper! Shove that cock of your as deep into my ass as you can, you fucking beast! Make Aunt Becky scream, make me beg, Make me fucking beg! Oh fuck, that’s it, make me cum, make me squirt my fucking juices all over you, oh fuck that feels good! Yes, yes, oh fuck yeah, you’re gonna make me cum you fucking beast, you’re gonna make fucking cum! Oh God yes, that’s it, yes, yes, yes, oh God, yes, yes, fuck it, fuck it, yes, yes, oh fuck here I cuuuuuuuummmm!" Becky was cumming, squirting, and screaming. Mary had stopped to try to figure out what was making Becky so crazy. As she tried to sit up, she was painfully reminded of the two large carrots buried deep in her ass, as they poked and pressed against her stomach, and continued stretching her sphincter, from the inside. The new sensation of having her ass stuffed so full and seeing her baby sister getting her brains fucked out by her dog, while screaming in orgasm, sent Mary straight into her own orgasm. Mary laid back down and started pounding away at her own pussy, shoving that carrot in as deep as it would go, before pulling it back and starting all over again. Within seconds, Mary was now too screaming out and squirting in orgasm. "Oh, oh, oh God yes, oh fuck, oh fuck yes! Oh God that feels good, oh fuck, oh fuck, oh God yes, yes, yes, oh my God, I’ve never cum so fucking hard in my life! Oh God yes, oh fuck, oh God, o holy shit, oh God I’m cumming, holy shit, I can’t stop cumming! Oh fuck that feels so fucking good, oh God, I’m gonna cum again! Oh yes, yes, oh my God, oh fuck, oh fuck, oh my God, oh God am I cumming. Oh shit this feels good! Oh God, why haven’t I ever done this before, oh fuck me, oh God fuck me!" As Mary continued cumming, she continued squirting her cum right into Becky’s face. Becky too was cumming almost non-stop. As Buddy pounded away at his bitch’s ass, his knot was getting bigger and bigger. Becky could now feel his knot being pushed against her rim. Becky knew what was coming. Despite her years of getting fucked up the ass, she still was not stretched enough to take Buddy’s knot without excruciating pain. Once she got his knot past her sphincter she was okay, it was just getting it through that tight anal muscle. As Buddy started to push his knot into Becky’s ass, Becky thought someone was trying to force a watermelon up her ass. For a moment, she had sympathy for her older sister, still trying to get used to having two carrot forced into her bowels. Becky let out with an incredibly load scream, as Buddy’s knot began to pierce her sphincter. "Oh fucking son of a bitch, oh God, oh God, oh God, get it in there your bastard, get it in there!" Becky was screaming. "Oh God damn you, don’t stop there, keep pushing, keep pushing." Becky began to beg! For some reason, Buddy was not able to push his knot all the way inside of Becky’s ass. Now they were stuck with Buddy’s knot wedged into Becky’s sphincter with no way to push it in or pull it out. Becky was in true agony. "Oh, you fucking beast, what the fuck are you doing to me! Get that fucking knot in there, what the fuck are you waiting for?" Finally, Becky realized that with her being so high up on the bed, Buddy’s legs could not reach any further. If she was going to get released from this pain, she was going to have to make it happen. Buddy was pounding away at her ass as hard and as fast as he could. Becky was finally able to lever herself just enough where she could met Buddy’s thrusts and finally push herself back just enough to get that knot out of her sphincter and buried in her stomach were it belonged. Becky thought for sure he had ripped her asshole wide open and that blood was probably pouring from her asshole. She felt wetter than usual, but then again she could just be sweating more too. It would be a while before she could know for sure. With Buddy’s knot now firmly embedded in her ass, Becky could get back to some serious orgasms. Meanwhile, all of Becky’s screaming and begging had Mary so turned on, she was almost blacking out from the intensity of her non-stop orgasms. Becky continued moaning, but now it was pure pleasure, instead of intense pain. Both sisters were in a world of their own, continuing their strings of non-stop, screaming, squirting orgasms. Eventually, Buddy shot his load deep into Becky’s bowels, again making her stomach bloat. Both Mary’s and Becky’s orgasms had started to subside. Because of the awkward position, Buddy was again unable to turn himself around. He spent most of his time licking the pussy juices from Becky’s back, hair, and neck, that Mary had shot at her during the height of her most intense orgasms. While Becky was stuck there, unable to move, with a 130-pound dog lying on her back, with his cock and knot still buried deep within her, Becky again turned her attention to Mary’s asshole. Becky grabbed a hold of both carrots and slowly started withdraw them from Mary’s ass, only to push them right back in again. At first, Mary was not sure of what to make of this new sensation, but it quickly began to turn her on, as she again could feel her orgasms start to build. Becky continued fucking Mary’s ass with those carrots until she felt Mary’s ass was loose enough for something bigger and better. As Mary lay back, moaning in yet another orgasm, Becky reached for her monster cucumber and began to lube it up. Becky continued fucking Mary’s ass with the carrots, pulling them out a little further each time. Finally, without warning, Becky pulled the carrots all the way out of Mary’s asshole and quickly replaced them with the cucumber. Mary again screamed out in horror. "Oh God no, don’t do this to me again, I was just starting to enjoy those! That’s too big, that’s too fucking big! Oh God no, please, take it out, oh God take it out!" This time, instead of gently working it into Mary’s ass, Becky shoved the whole cucumber deep into the bowels of Mary’s stomach. In one thrust, Becky managed to bury all but about 3 inches, before hitting some tough resistance. Mary continued to scream, begging for mercy, and thrashing about. Becky would show no mercy, she just kept pushing until every last inch was buried in Mary’s ass. Buddy’s knot had finally shrunk enough for Becky to get herself untied. Becky clenched down on her asshole as hard as she could, so as not to lose any of Buddy’s hot, thick cum. She then got herself up onto the bed and straddled Mary’s face, with her asshole line up over Mary’s still screaming mouth. Becky let her asshole loose and flooded Mary’s mouth with Buddy’s hot sperm, fresh from her bowels. At first, Mary started to choke, but as a reflex to keep herself from drowning, she began to swallow Buddy’s seed as fast as she could. Becky knew she was accomplishing two tasks at once. She was teaching Mary how to swallow great amounts of cum, while at the same time, getting her mind off of that gigantic faux cock up her ass, allowing her asshole to properly stretch enough for great anal sex with Buddy. Becky did stop and think about it however. If I have a hard time taking Buddy’s knot up the ass, how in the hell is my pussy ass sister ever gonna do it, Becky though to herself? Mary had swallowed as much of the cum from Becky’s ass as she could, except the cum that had run down the sides of her face. Mary was now licking out Becky’s still over-stretched asshole. Becky’s surprise and delight allowed her yet another orgasm, in which her pussy juice too flowed into Mary’s mouth as well. Mary was becoming one hell of an oral whore, Becky thought to herself. While Becky stayed on top of Mary, continuing to let her lick out her ass and pussy, Becky grabbed a handful of carrots and began working them into Mary’s empty cunt, one at a time. Mary was now about to experience the pleasure of being double fucked, even if it was at her sister’s hand, with a bunch of vegetables. Becky slowly worked the carrots into her sister’s cunt, one by one, stretching her open a little more with each carrot. With such a large cucumber up her ass, Becky thought she better stop with four. Becky could tell Mary was getting hot very quickly. The more Becky pumped away at her cunt, the less Mary was licking at Becky’s ass and pussy. Becky decided to get off of Mary’s face and allow her to concentrate only on her own pleasure. Mary had never experienced an orgasm from being double fucked, and Becky wanted her to be able to fully enjoy it. Becky worked her way back down to the bottom of the bed, so she could get a good grip on both the carrots in Mary’s cunt and the cucumber still buried deep in her anus. Becky began by alternating strokes. She would shove the carrots deep into Mary’s womb as she pulled the cucumber almost all of the way out of her ass. Then as she re-deposited the cucumber into Mary’s rectum, she would pull back on the carrots, bring them almost all the way out of her cunt. This new and unusual sensation sent waves of orgasms crashing down on Mary almost immediately. Mary was screaming in pure ecstasy. "Oh god, oh fuck, oh shit, oh god yes, yes, oh God, don’t stop, oh God fuck me, fuck the shit out of me, oh god, I can’t stop cumming, oh god, I can’t stop, oh fuck that’s good, oh god, oh god, oh god, oh yes, oh my fucking god, OH FUCK!!" Next, Becky tried double thrusting Mary, burying both the carrots and the cucumber deep into Mary’s body at the same time. Becky could actually feel the vegetables banging into each other within Mary’s body. Mary continued with the screaming orgasms, but now, you could no longer make out the words Mary was saying. After almost 30 minutes of non-stop fucking, rotating methods back and forth, Becky and Mary both had to stop, Becky from exhaustion from working so hard and Mary from cumming so hard. Becky pulled out both the carrots and the cucumber at the same time. The felling of fullness to emptiness was almost as painful for Mary as when they were first shoved into her body. Both sisters collapsed, were they lay, just lying in the afterglow of their feats, before falling asleep. About an hour later, Mary awoke with an urge to pee. As Mary walked into the bathroom, see looked in the mirror at her still naked body. Mary looked at her petite, but shapely, figure with a new, sexier, attitude. Mary had always tried her best to hide her body. She would even wear shorts and a T-shirt over her bathing suit at the beach. But now, thanks to Becky, and Buddy too, she was now turned on at the sight of her own body and she knew she wanted to start letting people see more of it. After Mary sat down and finished peeing, just wiping herself was now bringing her pleasure and turning her on. Mary sat there for a few moments and continued fingering herself and playing with her breast. Mary was getting horny fast and decided to do something about it. Mary returned to the bedroom to find Becky still sleeping, on her back, with her head close to the bottom of the bed, just as she was when she passed out from exhaustion. Mary walked over to Becky’s side of the bed and gathered up all her vegetable dildos and oil and moved them to the middle of the bed. Mary then returned to her side of the bed and gently sat down. Next, Mary rolled over onto her knees and moved more towards Becky until she was finally straddling Becky face. Without yet placing her pussy on Becky’s face, Mary bent down and started gently kissing and licking at and around Becky’s cunt. Before opening her eyes, Becky awoke with a smile and let out a low moan. "Mmmmm, that’s nice." Becky then opened her eyes to see Mary’s cunt inches away from her face. "Boy, do you know how to wake a girl up." Becky added. Becky was pleasantly surprised to see her shy, almost nun like, sister straddling her face and eating her out. Wow, Becky thought to herself, just 24 hours ago, Mary would have never even considered doing something like this, especially with her little sister. Becky was proud of Mary for being so aggressive, as well as herself, for bringing Mary out of her shell. Mary was no longer the quiet, timid, little girl Becky was familiar with. Mary was now becoming a sexy, confident, new woman. Becky quickly felt around for her remote control and pressed record. She did not want to miss a second of this action. While Mary continued pushing her tongue deeper into Becky’s cunt, Becky reached up, grabbed Mary’s hips, and pulled Mary’s pussy to her mouth. Becky too started licking and kissing at her sister’s pussy. Both sisters continued eating each other’s pussy, stopping occasionally, just long enough to let out a moan of passion and pleasure. To Becky’s pleasant surprise, Mary also began fucking her with the carrots she had grabbed before making her move onto Becky. In order to slowly build on her sister’s pleasure, Mary started with just one carrot. She first used the carrot to tease Becky by rubbing it against her pussy lips and clit, then pushing it against her opening, only to pull it right back out again. Mary was beginning to drive Becky wild. Becky so badly wanted to be penetrated, that as soon as she felt the carrot at the opening of her pussy, she would thrust her hips upward to try to force the carrot into her snatch. However, Mary was a quick learner and would pull it back as soon as she felt her sister’s weight begin to shift. "Oh you fucking bitch." Becky moaned, after about the fourth or fifth attempt. Mary was enjoying the power she had over her sister in more ways than one. The more Becky tried, the harder and deeper Becky would suck and tongue fuck Mary’s cunt. Mary finally gave in to Becky’s pleas and quickly buried the first carrot as deep into Becky’s cunt as she could get it. That immediately sent Becky into a long anticipated orgasm. Mary enjoyed it as well, licking up as much of Becky’s cum juice as she could catch as it oozed out of her wet pussy. Mary quickly grabbed another carrot and began teasing her baby sister’s rosebud. Once again, Mary would rub it up and down the crack of Becky’s ass and slowly began to push it against her sphincter, then pull it back just as her sphincter would begin to open. Becky continued going crazy with lust and the need to have her ass filled with that carrot. Becky continued passionately eating away at Mary’s pussy, clit, and asshole, grabbing and squeezing handfuls of Mary’s ass cheeks during her fits of frustration. This was turning Mary on all the more, causing her continuous orgasms to increase in intensity. Mary was loving have this type of control over her new sexual partner. Again, after several minute of intense teasing, Mary finally satisfied Becky’s needs by shoving the carrot as deep into Becky’s bowels as she could push it. Becky again let loose with a wonderful orgasm, this time causing her to squirt ever so lightly. "Oh God," Becky moaned, "do you know what you are doing to me? Oh fuck you are making me cum so fucking hard! Don’t stop," Becky continued, "don’t you even think of fucking stopping!" Mary decided she too wanted to know the pleasure of penetration, so she grabbed a handful of carrots and passed them back to her sister. Becky immediately started to repay her sister for making her cum so hard and so good. As she continued to lick deep into the folds of Mary’s pussy, Becky took her first carrot and began stimulating Mary’s clit, once again increasing the frequency and intensity of Mary’s orgasms. Mary too began leaking pussy juices. Becky was enjoy being on the bottom for once as Mary’s pussy cum could flow right into Becky’s mouth and she could taste and savor every last drop. Both sisters were now fucking and sucking each other to almost non- stop orgasms. Mary continued double fucking her little sister, with a carrot in both her cunt and asshole, while Becky was just beginning to work the first carrot into Mary’s still tight cunt. Suddenly, without warning, Mary withdrew both vegetables from Becky’s holes. "Oh God no," Becky cried, "don’t stop, oh please don’t stop!" Mary ignored Becky’s pleas and again began teasing her with just her tongue. Mary continued this until she could see Becky’s hole begin close and tighten up. While busy sucking and fucking Mary’s cunt, Becky continued thrusting her hips as if begging to again have her holes filled. Mary continued to let Becky beg until she decided it was time for her next move. Becky had buried her first carrot deeply into Mary’s cunt and had grabbed a second carrot and was again teasing her clit as she plunged the first carrot in and out of Mary’s dripping cunt. After Mary had recovered from her most recent orgasm, she slowly reached for her next vegetable dildo, in hopes that Becky would not see what see was going to do next. Mary again was teasing Becky’s holes, this time rotating pushing the carrot against Becky’s cunt, before pulling back, the doing the same with her asshole. Again, this was driving Becky wild. "Oh God, please, please put it in me." Becky cried. "I need to be fucked, oh God I want to be full, please fuck me with those, oh god please fuck me!" Mary decided to do just what Becky was pleading for. Without any warning, or any lube other than her own pussy juices running down her ass, Mary grabbed that super sized cucumber and rammed it up Becky’s ass as hard and as fast as she could. In a combination of shock, terror, pleasure, and pain, Becky let out an ear-piercing scream. "Oh god!" Becky screamed "Holy shit, oh fuck, oh Goddamn, oh God that hurts! What the fuck are you doing to me, oh my god, oh my fucking God! Oh God, oh God, oh fucking shit." Becky continued to scream, all the while squirting in the most incredible orgasm she had ever had! Becky was shocked that her sister would do something so brutal to her and yet the searing pain made her orgasms even stronger and better. It took Becky quite a while to get used to the sudden intrusion of her asshole, but she was loving every second of it. As Becky continued moaning, screaming, and thrashing about, Mary continued her sexual assault on her sister. Mary was licking up as much juice from Becky’s pussy as she could catch. Mary then started filling up Becky’s cunt with as many carrots as she could cram in there. With every carrot added, Becky felt as if she were being stretched to new limits. Her squirting was like one continuous stream that Mary could no longer keep up with. Mary would swallow as much as she could before having to stop and catch her breath, then gong back down for another drink. All the while Becky’s screams and moans continued like a chorus. "Oh God yes, oh fuck, oh God that feels so fucking good! Oh God, I am so fucking full! Oh God yes, don’t stop, fuck me you fucking bitch, make me cum, oh God you’re making me fucking cum! I am cumming so fucking hard, oh shit I think I’m gonna fucking explode! Oh fuck that feels so fucking good, oh God that feels good! Don’t stop, don’t ever fucking stop!" Just as before, all of the noise and commotion managed to grab Buddy’s attention. Without knowing it, Buddy had been watching everything that had been going on over the past 45 minutes. Buddy could smell and sense all of the cum and pussy juices and was getting hornier by the minute. In the position the girls had started in, there was no room for Buddy to get on the bed, so he too could be involved in this fuck session. But, with all of the thrashing around and moving of the sisters in their 69 position, Buddy had spotted an opening for himself and quickly jumped onto the bed. Mary was so involved in filling her sister’s holes to the max, she did not notice Buddy’s presence. Becky could see that Buddy had already had a ragging hard on and was just looking for a hole to bury his huge dick in. Becky continued to move around so she could allow Buddy all the room he needed to line up his cock with Mary’s holes. With Mary still on top of Becky, she was in the perfect position for Buddy to mount her. Becky still had a carrot shoved into Mary’s pussy, so this left only one opening for Buddy, Mary’s asshole. Becky knew this was going to be a tight and painful fit for Mary. However, after what Mary had done to Becky earlier, with the cucumber, she decided Mary had deserved what she was about to get and she also knew that Mary was at the point to were she would eventually be able to enjoy it. Without warning, Buddy jumped onto Mary’s back. Before Mary had a chance to react, Buddy began to sink his enormous cock into Mary’s ass. "Oh God no!" Mary screamed. It was too late, between Becky licking at Mary’s asshole and Buddy’s slimy cock, Buddy had forced himself into Mary’s ass with little resistance. "Oh God no, make him stop, oh please Becky, please make him stop!" Mary cried out. Becky could not have stopped Buddy even if she wanted to. Buddy was thrusting himself against Mary like a jackhammer and Becky had the view of a lifetime. Mary continued begging and screaming for Buddy to stop, to no avail. "Oh God, please no, oh God make him stop, he’s too big, oh God he’s too big! Stop Buddy, oh please stop, that hurts, I can’t take this, oh God it hurts! Stop please, oh fuck please stop!" In an effort to help Mary relax and accept this anal pounding, Becky began fucking Mary with one carrot while sucking and teasing her clit with another. Mary continued to beg and plead for another 10 minutes before finally becoming accustomed to the girth buried in her ass. Becky was almost starting to feel sorry for Mary, thinking that maybe she had pushed Mary too far, too fast. Those thoughts were quickly extinguished as Mary let loose with her first of many, screaming and squirting orgasms. Mary’s screams of pain and anguish were soon changed to moans of lust and pleasure. "Oh fuck yes, oh God yes, fuck me you bastard, fuck me good! Oh God yes, make me cum, make me fucking cum! Yes, yes, oh fuck yes, I’m gonna cum, yes, yes, oh God yes! I’m gonna cum, I’m gonna cum, oh fuck, yes, yes, oh fuck I’m CUMMING!!" Mary continued to scream as she over flowed Becky’s mouth, time and time again, with her squirting juices and cum! Becky, still having her own asshole and pussy stuffed, was enjoying this as well. Just the sight of her sister’s asshole being stuffed full of doggie cock was enough to keep her cumming. Having both of her holes stretched to their limits and fucking her sister’s pussy with carrots were just added bonuses. As Buddy continued pounding away at Mary’s tight little ass, Becky could see Buddy’s knot begin to swell. She knew the best was yet to come. Before too long, Mary could feel Buddy’s knot begin to hit against her already over-stretched sphincter. Mary began to flash back to the events of Saturday morning in horror. Even with her new found sexual abilities, Mary was not sure if she would be able to handle the pain of once again being knotted up her ass. Becky could sense the tension building in Mary’s body and began to double her efforts on her Mary’s pussy and clit, in an attempt to override the fear. Buddy began increasing the power of his thrust in order to knot his bitch. Buddy was now thrusting so hard, it was causing Mary’s head to knock against the headboard of the bed. Becky could see, up close and personal, Mary’s sphincter being forced open, wider than she ever imagined possible, as Buddy’s knot slow began pushing it’s way into Mary’s bowel. Becky was amazed at how much Mary’s asshole had to be stretched open for Buddy’s knot to be able to enter. Becky thought proudly for a second that her asshole too had been stretched that far open, on several occasions throughout the weekend, as she too was knotted by that incredible beast. Mary’s moans of joy again turned to screams of agony, snapping Becky back to the moment at hand, as Mary begged for Becky to help her. "Oh God no, I can’t take this!" Mary screamed. "Oh God Becky, make him stop, oh God, please make him stop! It hurts too much, I can’t take anymore, please, please, make him stop! Oh God Becky, please don’t let him do this to me, you’ve got to make him stop." Becky thought for a second as whether or not to intervene. Becky did not want to see her sister suffer, but she also knew that once the initial shock was over, Mary would once again enjoy being fucked and stuffed so full, not to mention that warm, wonderful feeling of having Buddy’s cum deep inside her stomach. Becky decided to again, redouble her efforts on Mary’s cunt and let nature take its course. After another few minutes of Mary’s begging and screaming, Buddy had finally knotted his bitch and Mary was once again enjoying being fucked to the hilt. Becky decided to give Mary the added pleasure of being doubly full as she continued fucking Mary’s cunt with more and more carrots. Mary’s holes were now as full, if not fuller than Becky’s. Mary seemed now to being having one long, non-stop, intense orgasm, once again squirting a steady stream of pussy cum into Becky’s mouth. Before too long, Buddy began to empty his seed deep into the pit of Mary’s stomach. Becky was amazed as she watched Mary’s stomach slowly expand as Buddy continued emptying his balls deep inside of Mary’s intestines. Becky’s own orgasms continued to intensify with what she was witnessing so close to her face and with the anticipation of being able to drink up all of Buddy’s cum as it flowed out of Mary’s asshole, straight into her waiting mouth. After close to 20 minutes of Buddy filling Mary’s bowels with his sperm, Buddy had finally emptied his ball sacks and was ready to turn around and wait for his knot to shrink, so he could get untied from his bitch. In doing so however, Buddy ran out of space on the bed and his front paws slipped off of the bed. The pressure of Buddy’s weight hanging off of the bed was pulling violently against the knot, still buried deep inside of Mary’s ass. Buddy was now trying with all of his might to pull his still swollen knot out of Mary’s clenched asshole. Mary felt as if she were trying to shit a bowling ball out of her ass. The pain was more intense than she had ever experienced, much worse than being knotted it self. "Oh God," Mary screamed, "make him stop, oh God make him stop! Take it out, take it out, oh fuck it hurts! Please help me Becky, please make it stop!" Becky, Mary, nor Buddy knew what to do in this awkward situation. Becky tried her best to try to soothe her sister’s pain, while at the same time try to pull back against Buddy’s weight. Becky could see Mary’s sphincter trying to open wider, but it was not physically possible. Finally after about 15 minutes of being stuck in the precarious position, Buddy’s knot had shrunk just enough to allow Mary’s asshole to open up enough to let Buddy escape. Once released, Mary was lunged forward with her efforts to free herself from this pain. Her asshole was stretched open so wide, that all of Buddy’s thick cum came out in one gigantic blob, right onto Becky’s face. Mary was so relieved to be rid of the pressure against her asshole she collapsed right on top of Becky and did not move. Becky could tell Mary was okay by the feeling of her breathing against her body. Once Becky managed to clear the cum from her eyes, she was shocked to see the size of Mary’s still over- stretched asshole. Becky could easily put her entire fist inside of Mary’s asshole, with almost no resistance. Unsure if Mary was up to it, Becky did just that. Becky slowly began fisting Mary’s asshole, to see what type of response she would get. At first Mary did not react, but as Mary began to enjoy this stimulation, Becky increased her tempo. Within minutes, Mary was screaming out in lust and cumming harder than Becky had ever seen her cum. Becky slowly worked her fist deeper and deeper into Mary’s guts, until she was almost in up to her elbow. Mary had both hands clenched around the bed’s headboard, thrashing her head up and down as she continued to cum. Becky then decided to go all the way with this. Becky quickly remove all of the carrots from Mary’s cunt and quickly replaced them with her other hand. Becky was now double fist fucking her only sister. Mary was squirting her cum all over Becky’s face and body, adding to the mess of cum, left by Buddy, up Mary’s ass, that had poured onto Becky. With her own holes still full of those faux, vegetable cocks, her body half covered in cum, and both arms deep inside her sister's body, Becky was in sexual heaven. Becky want very much to have Mary either pump her already full holes with the vegetables that were already in them, or to have Mary double fist her back, but Mary was in sexual state that could not be disturbed. Mary was cumming and screaming as hard and as loud as humanly possible. Becky was not sure how muck longer Mary could last before finally blacking out from sexual overload. Becky continued for another 15 minutes before she could no longer continue. Her arms were worn out from pumping her sister as hard as she could and her mind and the rest of her body were exhausted from the new heights of sexual pleasure. When Becky finally removed both fists from Mary’s holes, Mary indeed passed out from exhaustion. After lying there for several more minutes, Becky had finally gained enough strength to roll Mary off of her and onto her own side of the bed. Becky then began pulling the carrots from her own cunt, sucking on each one until it was cleaned of her own cum. Once she had emptied her cunt, she began the task of removing that large cucumber from her ass. It had been up her ass so long, it was becoming a natural feeling to Becky and was becoming painful to pull out as the widest part pulled through her sphincter. Becky had to literally shit the cucumber out of her ass. That feeling alone brought her to yet another orgasm. Once it was out and Mary was still asleep, Becky began fisting her own asshole to one final, squirting orgasm before to passing out from sexual exhaustion. Mary and Becky awoke a couple hours later. It was almost 6:00pm. Mary knew her parents would soon be dropping the boys off and her weekend of what she thought would be peace and quiet would soon be over. Tomorrow it would start all over again. The hustle and bustle of work, getting the boys to school, and just being a single parent once again. At least now, she knew she had some hope of having a little more excitement in her life. With all Becky had taught her, Mary knew she would have many wonderful nights of mind-blowing sex with her new found sexual partner, Buddy. She had also hoped that from time to time, she and Becky would be able to continue their newfound relationship too. Mary and Becky stayed in bed a little while longer, holding, kissing, and caressing each other, before taking one last shower together. As Becky and Mary were cleaning up their mess and getting dressed, Becky asked Mary, "Well, how did you enjoy your weekend?" "Oh God Becky, it was awesome, I loved every second we spent together." Mary answered. "Do you think we could ever do this again sometime?" Mary questioned. "I sure hope so!" Becky answered back. "Between you and that incredible dog of yours, I have cum more in the past 2 days than I have in my entire life. We have to figure out a way to get the boys out of the house more often. The next time I come over though, I am going to be prepared. I have some toys and dildos that will blow your mind. You think those carrots and that cucumber felt good, you ain’t seen nothin’ yet, but do hang on to that cucumber for as long as you can, that bitch is sweet! Like I told you, we are going to have share that dog of your too. I have never been fucked with a cock as good as his and I intend to get a lot more of it!" "Good," Mary replied, "I am glad you feel that way. I was afraid this was a one time only thing and I was going to miss it." "We’ve only just begun baby." Becky replied. "Oh, by the way," Becky began, "if you ever want to relive this day, I have it all on tape." "What are you talking about?" Mary asked. Becky walked over the dresser and uncovered the camera. "I found this in your closet, I hope you don’t mind? This was a weekend I never want to forget. I was not sure what your reaction was going to be, so I hid the camera just in case. I figured one of two things was going to happen." Becky continued. "Either you were going to hate me and try to get me in trouble, or you were going to love it. If you were mad, I was going to have to blackmail you with this tape, but seeing as how you enjoyed it as much as I did, I will make you a copy and you can enjoy it sometime when you are alone and horny. This is going to be the highlight of my collection." Becky added. "Collection?" Mary gasped. "Well, I have had a few adventures," Becky explained, "but nothing even comes close to this weekend." Becky helped Mary clean up the rest of the house. Becky wanted to make sure and be gone before her parents arrived with Mary’s boys. Becky knew if her parents saw her wearing one of Mary’s tight shirts, with no bra, she would never hear the end of it. As Becky was leaving, Mary stopped and said, "I don’t know what to say or even how to thank you." "I told you that you would be thanking me before this weekend was over." Becky gloated. As Becky was leaving, she grabbed Mary, gave her a deep, passionate kiss, grabbed Mary’s tit with one hand and slid her other down Mary’s shorts for one last finger fuck of that still wet, tight pussy and walked out the door sucking, Mary’s juices from her fingers.
