My Sister's Surprise
By WhoDaMan

Chapter 1

I am constantly pranking my sister. She is 2 years younger than me. She plots her revenge, only she got way more than she bargained for.

My name is Nick. I am 15 years old. My sister Tammy is 13 years old. We get along OK. Things are pretty normal around our house. The only thing is, I do enjoy playing pranks on my sister. We really didn't mess with each other that much until she invaded my privacy trying to get a peek at me naked and embarrass me. I was 13 at the time and she was 11. She had her friend Nancy over one weekend spending the night. I had come home from playing football with my buds and was messy. Mom told me to take shower before doing anything else. Apparently my sister had been plotting with her friend to catch me naked. As I was taking my shower, they popped the lock on the door with a screw driver. They snuck into the bathroom. My sister was standing there with a camera and her friend walked over and pulled the curtain open. I guess they didn't practice or anything, because it didn't go as they planned. I heard the noise as they came in. I grabbed the edge of the curtain to hold the bottom closed as I looked to see what was going on. As her friend gabbed the curtain to swing it open, she only proceeded to move it 6 inches since I had it in my hands. I almost lost my grip on it because I wasn't expecting the curtain to be pulled back, but fortunately it didn't. Her friend however was standing close enough, that she got a glimpse of my penis and a good view of my ass in profile. I yelled at them and that startled her friend who immediately ran to get out of the bathroom. She practically knocked my sister over on her way past. I grabbed my towel and quickly wrapped it around myself and jumped out of the shower as my sister got back up and was scrambling out of the bathroom. She had dropped the camera during the collision. I closed the door, locked it, and yelled that I was telling mom and she was in for it!. I went through the camera and looked for any bad pictures. She did take a few pictures, but nothing was visible in the photos. She hadn't gotten to see me. I decided to hold on to the camera. She had no way of knowing what she caught on there and I could use it as leverage. When I had finished my shower, I unlocked the door and opened it. There was my sister and her friend sitting on the floor. She looked for her camera and grabbed for it. I pulled back and held on to it. "Oh, no you don't! This is proof that you are a sick and twisted pervert. Mom thinks your just a goodie-two-shoes. Now I have proof!" Then she started apologizing and begging me not to tell mom. "Why should I let you off the hook you little pervert?" I asked. "I am so sorry. I didn't see anything, I promise!" Her friend, not fearing any trouble was not so nice. "I did!" she said. I was a little embarrassed. I didn't know what all she did see. I know from what I had seen in gym class that I was normal, probably even getting through puberty earlier than most of the boys at school, but it was still an invasion of my privacy and I blushed. "I will think about it. You will have to find a way to make up for it you owe me and I owe you!" I told her.

We made it through dinner. I didn't tell on her. I did however give her some mean stares through out dinner. She had a worried look on her face the entire time. At anytime, I could tell mom and dad what she had done and she would be toast. Later that night, she and her friend came to my room. Lucky for me they knocked. I had been so turned on by her friend seeing me naked, that I was doing what all teenage boys do at that age. I had my eyes closed. I was imagining the scenario going as they had planned and being exposed to them both. I was masturbating furiously and had just gotten that feeling as your testicles tighten up and you know your about to burst. As they knocked on the door I let go of the biggest load I had shot up to that point in my short self pleasuring career. "Just a second!" I said. I quickly wiped the mess up and pulled my pants up. I didn't have time to put my shirt on. I reached over and opened the door. "What do you two twerps want?" I said as I grabbed my t-shirt and slipped it on. My sister's friend was staring as I slid on my shirt apparently enjoying the view. "So, we were talking. I know we need to do something to make up for earlier. I want my camera back and really don't want to get into trouble!" "So?..." I asked. "Well, we were thinking, since Nancy saw you, uh, well, uh... saw some of you, that she would take her shirt off if you promise not to tell. You can't touch and you can't ever say anything to anybody! Is that fair?" I hadn't really seen a real live girl half naked before. It was very exciting. "OK, but she has to stand there and let me look until I say I'm done" I informed her. "10 seconds, that's all!" Nancy countered. I could tell she was agitated and embarrassed already. I had to quickly agree before they changed their mind. "OK, 10 seconds" I said. They stepped into my room. My sister closed the door and locked it. We stood there for a second. I looked at Nancy, held my hands out palms up and and gave her the "Well..." look. She started undoing her blouse. She took it off. She was wearing a training bra. I hadn't really thought this through. 11 year old girls don't really have anything to show yet. She reached back and unsnapped her bra. She hesitated, then pulled the straps down off her shoulders. She immediately held her right forearm over her breasts as she removed her bra. I reached out as if asking for it and she handed it to me, not really thinking about it, I tossed it on the bed behind me. I know I had just cum, but I could tell I was getting a little aroused. She looked at my sister. Tammy nodded her head yes and tilted her head to point towards me indicating for her to go ahead. Nancy closed her eyes tight and dropped her hands to her side. My sister started counting. "One one thousand... two one thousand...". I just stared. This was forbidden territory. I was seeing a girls chest! She didn't really have anything that should excite you, but it was having access to something taboo. My sister was continuing to count. "Six one thousand... seven one thousand..." I blinked quickly, almost as if I were taking mental snapshots. "Nine one thousand... ten one thousand" Nancy moved her arms to cover up and opened her eyes. She was red as a beet. She looked into my eyes to see what I was thinking. I was sure she must have seen the stunned look on my face. She reached down, grabbed her shirt. She spun around with her back to me and put it on. My sister opened the door and they ran out and down to her room. I stepped back and sat on the bed. I fell back and realized her bra was under me. I pulled it out and looked at it. I folder the 2 sides together. I rubbed it on my face and sniffed it. I don't remember any scent, just that as I did that, I reached down and rubbed my cock through my pants. Just then the door opened and my sister ran over and grabbed the bra out of my hands. "What a pervert!" she said as she ran out the door. "Takes one to know one!" I yelled back in my most immature voice. What a day this turned out to be!

So, I had vowed revenge. It had been over a year since the invasion of my privacy and flashing me. I hadn't really found an opportunity to get that revenge to this point. Sometimes, its just a matter of taking advantage of opportunities. Last year, at Halloween, my parents, my sister, 2 of her friends Sheila and Nancy, and 1 of my friends Joe were at our home. We were playing some games with a Halloween twist on them. My parents had set up some props around our house and yard to be scary. We kids sat in a circle. My mom had a bottle and she spun it. Who ever it pointed at had to roll a dice. There were 6 stations set up. Mom kept track of who had to go to which scary location. If you had visited one, you rolled again. Dad would usually escort the victim to the location and sometimes had something to do with scaring you. On my first roll, I got a four. I had to go to my parents bedroom. I walked in. There was a very dim light. Dad closed the door. Suddenly a bunch of hairy toy spiders were dropped from the ceiling on me just as the lights were turned on. They all had strings tied to them from the door, so they could reset the prank. I jumped like a scared little girl. This year, unbenonced to us, my dad had setup a camera at 3 of the 6 pranks, including the spider one. We later would watch as each person entered and got the shock of their life. We had worked our way through the group. I did the lame 'ghosts' in the bathroom visit, Had to walk through the slime covered garage in the dark. Got video taped again with the skeleton in the closet prank. I even did the stupid bats in the family room that were 'flying around' attached to the ceiling fan. My favorite and the scariest, was the werewolf in my sister's bedroom. It was another one that was video taped. As you enter the room, it is again dimly lit. You can just barely see a shadow in the direction of the bed. You are guided right to the edge of the bed. Suddenly the lights come on and right in front of you is a life sized werewolf. The head was amazing. The rest of it was just a hoodie under the mask on a broom and some PVC pipe through the arms to hold it up like it was on someone, which was kind of lame, but you don't notice that because the face is like 2 feet in front of you and grabs your attention. As everyone goes to each station, you hear screams, but there really were no sound effects. I had done the werewolf as my 3rd visit. I noticed my sister had not done that one yet. On her last turn, she had done all the others so she didn't need to roll the dice. She was informed to follow dad. As she met him at the door and he did his vampire voice and talked to her and made his way slowly to the bedroom, I jumped up, and slipped out through the kitchen and down the hall to her room. I went in and put on the hoodie and the mask. I got in the same position on the bed. I waited as the door slowly opened. I had been in there a long enough that my eyes were adjusting to the darkness. In the dim light, I could see dad hit the record button on his remote. He led my sister by the shoulder to the edge of the bed. He stepped back. I took a deep breath. The lights came on and my sister screamed at the sight of the werewolf mask. My dad laughed and said "That was a good one sweetie!". My sister let out a forced chuckle as she turned and looked at him and then looked back at the werewolf mask. Just as she looked back, I jumped towards her and let out a really loud growl! She freaked! She screamed and took off running. I chased her. As I passed him, I heard my dad start laughing. We saw later on the video that I had scared the crap out of him too, then as he realized what was going on, he began laughing. I chased my sister all the way out the front door of the house. She was screaming the entire time. I scared her so bad she peed her pants. Everyone knows there is no such thing as werewolves, so after the initial shock, everyone in the living room was laughing after I passed by as well. I stopped at the end of the sidewalk under the lamp by our mailbox. My sister was about 2 houses away still screaming and watching to see what I would do. I took the mask off and was laughing so hard I was getting cramps. She was furious. She ran back to the house and started punching and slapping me while I was still laughing. My dad had caught up to us and he grabbed her arms to hold her and calm her down. Everyone came outside. Dad was trying to calm her and saying "Honey, it was just a harmless prank. You'll look back on this soon and laugh about it." "No I won't!" she insisted. That was when we noticed her wet jeans. A few of us were pointing and laughing. She looked down. She let out an embarrassed scream and ran into the house. She ran straight to her room and locked the door. My dad, her friends and even myself tried to get her to come out of her room. She wouldn't budge. It took weeks for her to talk to me again. She vowed she would get revenge on me one day. From time to time she would be reminded by some of us about the 'incident'. She would turn red with anger and embarrassment and reassure us that she would get revenge.

We went as a family to the local zoo one weekend about 4 months later. It was still too chilly out to do summer things like going to the swimming pool or playing hoops at the park. Bundled up a little, we wandered through the zoo checking out the different animals and displays. At one point we entered a building covered in vines and with painted on shrubbery. It was the snake exhibit. I immediately started to hyperventilate. I am deathly afraid of snakes. I have no idea why. Just seeing them on TV, in the movies, anywhere, was enough to raise my heartbeat and my breathing. At this point my anxiety level was through the roof! Mom knew I couldn't do this! Why did she bring me in here? "Honey, I thought maybe this would help you get over it" she reasoned. I headed back to the exit and found a bench. I sat down and tried to control myself. Eventually they came out. Everyone could see I was visibly upset, but I didn't say anything. I was ready to go home. We made our way back towards the parking lot, stopping at a few more exhibits, then we left. I didn't know it then, but my sister was formulating a plan to get back at me for the werewolf prank.

I had been at the pool with some friends. This girl I liked was there with some of her friends. God I love bikinis. She was hot! I could hardly keep my erection from just bursting out and yelling "Hello!" It was a very exciting and frustrating afternoon. We did get to talk some and at one point, we did chicken fights. She climbed on my shoulders! I couldn't help it. All I could think of was the fact that I got to touch her body as she climbed on my shoulders and the fact that her pussy was right there on my neck! I was hard as a rock. Thank God we were in the water!. We played around briefly until the lifeguard made us stop. Apparently, too many people had been hurt doing chicken fights and it was banned. I let her down. She held onto my shoulder. Her right hand wrapped around my back and holding my side, her legs wrapped around my lower torso. Her thigh was rubbing my hard on! It was awesome!. At one point I caught myself sort of humping her leg, rubbing my cock along side of her thigh. I quickly stopped my self. She just put her chin on my shoulder and hugged me and smiled a sheepish grin. Not too much later, it was time to go. We had to be home for dinner by 6. If we were late, it was trouble. Too many times I got a two week restriction just for that. I said goodbye to Janet as her mom picked her and her friends up. I jumped on my 10 speed and hurried home.

I went up to my room. I quickly locked the door. I removed my wet swim suit. I grabbed a towel and dried my self. Head chest, back, legs, oh, and my throbbing erection. I went to my desk and sat down. I openned up my computer browser. I pulled up some photos I had of Janet in her bikini and other shots. I masturbated furiously. It didn't take long. I suddenly tilted my head back, closed my eyes, "Oh Janet, I love you!" I said as I pictured her naked and shot my load. Suddenly I heard something that snapped me out of my fantasy. I was still stroking and cumming, just not as fast. I looked down. I slid my chair out. Holy shit! My sister dropped the fake python in her hand and was pulling the werewolf mask off her head, wiping my cum out of her eyes. Tammy didn't say a word. I couldn't tell if she was angry or in shock, or what. She got up, walked over to my closet and opened the louvered doors. She grabbed her friends by the arm. They looked in each others eyes and both put one hand over their mouths. and Nancy had a video camera in her other hand. Tammy quickly unlocked my door, reached back again and dragged her friend out. Nancy was still trying to video tape as I continued to stroke since I was still cumming. I heard Nancy burst into laughter as they headed to Tammy's room. They went in, locked the door. Oh shit! She had a video camera! Your mind doesn't work as fast when you are in the 'throws' of ecstasy! I quickly took my towel and wiped myself up and put on some pants. I went to her room. I tried the knob. "Tammy open up!" All I heard was another burst of laughter.
