The Sexual Education of Yumi - When Three Becomes Four

by MargaretSexyMum

There is some male and female sexual activity in this chapter. If that is something you find distasteful you might either skip those bits or even this chapter all together.

Mieko's heart races a she sees her sister at the airport. Hugs are shared and tears shed. She is amazed at how big Keiko's belly is in the 7th month of her pregnancy, until her sister explains she is expecting twins, just like they are.

Meiko sees her seven year old niece standing alongside her mother and she almost gasps as Yumi is wearing the pretty Japanese school uniform that her mother had bought for her and she is struck at how much she looks like Keiko at the same age - the age when their own sibling sexual exploration had begun. And seeing Yumi in the uniform has the same effect on Mieko as it had on Keiko the first time she saw her daughter wearing it. The girl is so excited at seeing her Aunty in personal that she twirls around, giggling, her skirt flying up and showing the plain white cotton panties beneath.

Mieko can feel the familiar damp spot forming in her panties as she admires them although she is not sure who is having that effect on her, her sexy pregnant sister or her petite preteen niece. As her nipples harden involuntarily and the itch gets stronger between her legs she fears it may be both. She does not know what the next few days and weeks will bring but the dryness in her mouth tells her it is not just trepidation she is feeling about her new living arrangements but also a strong, almost uncontrollable sense of sexual desire.

For her part, Keiko also feels a sexual longing for her sister, one that she has suppressed for some time. Hailing her in her arms again brings back so many romantic and sexual emotions and vivid memories. They break their embrace and share a very prim sisterly kiss on the lips, although one that lingers for perhaps a moment longer than a purely chaste kiss would. Yumi is standing watching the sisters kiss and doesn't want to be left out, she snuggles into their sides. Keiko formally introduces her to her Aunty who she has only seen before on Skype as Mieko has not visited since she was a baby.

As Mieko bends down to kiss her on the cheek Yumi turns slightly and their lips meet, the older woman feels the softness of the little girl's lips and her heart races. She cuddles her niece and can feel colour filling her cheeks as the her blush spreads. It may be her imagination but she thinks the kiss lingered longer than normal.

Yumi is so excited to see her aunt, who looks so like her mum, beautiful and elegant. She has long hair well past her bottom - a trait all three girls share.

Keiko marvels at how beautiful Yumi looks embracing her aunt and wonders if she will confide in her sister about the incestuous relationship she (and Samuel) have initiated with their sexually precocious daughter. Anyway the airport is not the time or place to pursue these thoughts so they collect Mieko's numerous bags and head home. Keiko jokes that it seems her sister has bought all her belongings and was coming to stay for good, Mieko chuckled nervously knowing it may not be far from the truth.

When they get to the house they take her bags inside and put them in her bedroom. Mieko notices there are only two bedrooms and she has been given Yumi's, which is decorated for a little girl, all fairies, princesses and butterflies on the walls. "I would be happy to sleep on the couch, I don't want to displace Yumi from her room."

"No that is fine, in fact I should explain that Yumi usually sleeps in our room. I know it is a little unusual given her age but I believe in attachment parenting where you let the children form a natural bond with their parents until they feel they want to create their own independent distance. I should probably also tell you that Yumi still breastfeeds sometimes, she hasn't shown interest in self-weaning yet, although she usually only has a morning and evening feed. I hope that doesn't shock you, I just felt I should warn you. It is something that feels natural for us and Sam is very supportive."

"No, it doesn't shock me sister, I would never question your parenting skills or how much you and Samuel love Yumi. I can tell that already and she is such a confident, intelligent and loving little girl. You should be very proud of her." What Mieko leaves unsaid is that the thought of the cute little 7year old suckling at her sister's teat arouses her very much.

Mieko inquires, "But doesn't that effect your sex life having Yumi in bed with you?"

Keiko chuckles as she runs her hands over her enormous belly, "obviously not sister. There are many places in this house for us to consummate our love, not just our marital bed .... and we take advantage of them all at any opportunity we get." Keiko becomes serious and says "We have a lot of catching up to do sister. I hope your visit can bring us back as close together as we once were."

They both contemplate how close they once were and the pangs of regret fill both their hearts as they realise how long they have been apart. They also think of the secrets they are keeping from each other and how they will try and explain where their lives are at because they both want to be open with the other and share their most intimate secrets. They love each deeply and have missed each other terribly. Now it is not just the two of them, Samuel and Yumi are an integral part of Keiko's life and Mieko needs to accept that if they are to establish the same close sibling bond.

They all have a leisurely dinner and then sit in the living room chatting happily about things of no substance but avoid raising any intimate matters.

Soon it is time for Yumi to go to bed. But before bed time it is bath time. Keiko excuses herself to help Yumi bathe. She calls from the bathroom for Mieko to come in and chat. Mieko trembles with trepidation as she approaches the bathroom. She sees Yumi in the bath, bubbles covering her nudity and breathes a sigh of relief. She tries not to stare at her beautiful niece as Keiko soaps her back and washes her hair while reminding Mieko or their own shared bath time when they were little. It is left unspoken but both sisters cant help but reminisce about their own shared baths and the sensual games they used to play together at Yumi's age.

Mieko feels herself begin to blush again and heat beginning to form in her panties as she watches Keiko soaping up Yumi's flat chest and then dipping beneath the water to scrub her bum and between her legs. She notices that Yumi let's her mother's hands roam all over her lithe frame and seems almost to be enjoying the gentle caresses.

When they finish Mieko is caught off guard when Yumi suddenly stands up, her tiny body covered with bubbles, but her flat chest and hairless cleft visible. When Keiko uses the shower head to wash off the soap her stunning nudity is fully exposed. Mieko realises her niece is delicious, her flat chest and tummy sits above a plump hairless vulva. Mieko licks her lips nervously as she admires the little girl.

Keiko asks Mieko to get a towel and as she does she sees Yumi squat slightly and let loose a strong stream of pee into the bath. Neither the little girl or her mother blink as she relieves herself, Mieko watches fascinated as her sister observes the girl pee, her face close enough to almost be splashed by the spray.

Yumi finally gets out of the bath and walks naked to her aunt, who opens the towel for her and envelopes her tiny body in the big fluffy towel. When Yumi makes no effort to take the towel and dry herself, Mieko begins to rub the girl dry, feeling her soft, thin body through the towel. She trembles as she rubs Yumi's pert little bum and quickly rubs between her legs, careful to be gentle and to not linger as she is aware her sister is watching her, a sweet smile in her face,

The little girl puts on her a pair of Cinderella panties that her mother hands to her and a matching Disney Princess short nighty which only comes down to her hips leaving her panties exposed. Yumi turns to Mieko and says "Come and read me a bedtime story Aunty."

They retire to the bedroom and Mieko sits at the end of the bed and picks up a Tinkerbell book and begins to read. Keiko is brushing Yumi's hair as she listens to the story and then the girl settles down beside her mother.

Mieko continues to read, and the next time she looks up her heart rises into her mouth. Keiko has exposed one breast and Yumi is nursing on it it. Mieko has never seen anything so beautiful and sensual. She notices that her sister's breasts are larger than she has ever seen them. She knows that normally her titties would be like her own an A-cup but now that she is lactating and has been for many years they seem to be at least one if not two cup sizes larger. Yumi's lips are sucking hard at her mother's nipple.

Keiko smiles, at her sister, "I hope this doesn't upset you. Yumi gets comfort from this and it sometimes helps her sleep. I never would have dreamed when she was born that she would still be breastfeeding seven and a half years later. At least I know my milk will still be strong when the twins come. Although this little minx" she says teasingly as she ruffles her daughter's hair, "is going to have to give up her booboo when they need their nourishment."

"N n n n no, that is ok" Mieko stammers staring at her her niece suckling on her sister's breast. She is actually wishing she could ask Keiko if she could suck a little on the other teat, as she wonders what her milk tastes like. Just at that moment she sees that opportunity pass as Yumi releases her attachment and begins to suckle on the other breast. Soon the little girl's sucking slows as she appears drowsy and then she nods off to sleep and Keiko removes her daughter from her breast. She slowly rises from the bed, her top still lowered below her breasts which are leaking a few droplets of breast milk.

Mieko can't help but notice how engorged her sisters nipples are. Her eyes widen in surprise. Keiko notices this and says "What?" when she sees her sisters expression.

"Nothing, its just I didn't realise your nipples were so long and thick. My own are much smaller, still larger than average, as we always had, but yours are huge."

"That is what extended breastfeeding will do to you, engorged nipples, not that it doesnt have its advantages, they are still very sensitive. You might find out when you have kids."

That is not likely Mieko replies as there is no boyfriend in the picture. Mieko doesn't mention at this point that there will never be a boyfriend in her life now or ever, she has decided she is a lesbian.

"Anyway," Mieko says "I am very tired from the trip and head off to bed, I will see you in the morning."

Mieko smiles, "Come here and give your sister a kiss goodnight, it has been a long time since we had that chance." Mieko walks over and kisses her on the cheek, Keiko moves her head so that the second kiss is on the lips, still just a soft touch of lips, just as Yumi did with her Aunt at the airport. But this time they do not part as quickly and the kiss deepens as the sisters enjoy the kiss as they have not had been able to kiss for many years, their lips part and soon they are French kissing, Mieko feeling her sister's large tummy pressing against her own belly.

They hear a drowsy voice from the bed as Yumi says "me too Aunty". Mieko pauses a moment uncertain about what to do, and looks over at her sister who just nods. Mieko leans down and plants another kiss on her niece's lips. Yumi reaches up to her Aunts head and pulls her in closer, delivering a long lingering kiss on her Aunty's lips. Mieko finally pulls back, panting slightly her face flushed and she feels her tummy trembling and a tingling in her panties. She can't believe the thrill she experienced as they were kissing and was surprised the little girl seemed to be such a good kisser. She begins to say good night to her niece, but the little girl has already drifted off to sleep.

Mieko goes to Yumi's bedroom and as she lays in the large bed she masturbates before going to sleep, her mind on the kiss from her sister and niece as she orgasms, looking around the room at the girly decorations and fantasising about Yumi's hairless vulva.

Mieko drifts off to sleep, but she tosses and turns in the strange bed, her mind a jumble of thoughts. She awakens and finds it difficult to get back to sleep. She looks at the clock to see she has only been asleep for about two hours. She decides to get up and take a walk as it a warm night.

She walks and breathes in the clean air, as she comes back to the house she passes near her sister's bedroom and hears noises coming from inside, it is the sound of passion. As she passes close to the full-length windows she sees that the curtains are open and there is lamplight shining through. When she looks in she is shocked.

Keiko is naked astride Samuel, bouncing up and down, impaled on his cock, her huge round belly and tits so beautiful as she rides her husband. She watches the passionate lovemaking and hears Keiko's load groans as the large cock slides between her labia and buries itself deep inside her cunt.

Then Mieko notices movement alongside the fucking couple. She had forgotten all about Yumi sharing a bed with her mother and father.

Mieko sees that Yumi is next to them in bed, still wearing the Cinderella nighty and panties she had on before and it looks to her that the little girl seems to be playing with herself with her hand rubbing her pantied crotch as she watches her mother and father fucking beside her. She is shocked that her sister and brother in law are so open in front of her, displaying themselves wantonly, with their own tiny voyeur watching their sexual passion. If Mieko is surprised by their exhibitionism she is open mouthed as Yumi proceeds to kiss her mother and then her father as they continue their frantic coupling, all the time watching her pregnant mummy takes the enormous prick all the way inside her. Mieko realises now why the little girl had been such a good kisser, she must have had a lot of practice - with her own mummy and daddy.

Yumi then reaches down and Mieko sees the little pixie slide her panties down her thighs and off, exposing her prefect vulva again, the bald mons looking so sweet and innocent to the horny aunty. Mieko is even more astounded when Yumi hands her panties to her daddy who raises them to his nose and inhales deeply taking in his daughter's scent. Mieko notices Samuel's bum thrusts even harder off the bed as he penetrates his wife, driving his cock even deeper into her cunt. Then Keiko takes their daughter's knickers and also sniffs at the crotch. Mieko watches amazed as first Samuel and then Keiko sucks on the damp crotch of their daughter's panties while they continue to fuck. Yumi rubs her mummy's pregnant belly as she impales herself on his prick and the tiny hands reach up to squeeze her tits.

Keiko and Samuel reach a simultaneous climax, she screaming in delight as he fills her with his seed. When Keiko climbs off him Mieko can see the white sticky mess that drips from her sisters cunt back onto Samuel's cock and balls. Keiko dips a finger into the pool of cum and and licks her finger clean. The she dips her finger in again but this time she feeds it to their daughter who sucks her daddy's seed off her mother's finger.

They use their daughters soiled Cinderella panties to clean up the remaining mess. The three share an affectionate kiss and snuggle down naked into bed, with Yumi in the middle. Turning off the lights and going to sleep.

Mieko hands have been inside her panties masturbating as she observed the fucking. She now understands why her sister had chuckled when she had asked her about if their co-sleeping arrangement with their daughter had interfered with their sex life. No need to be quiet she guesses if their 7 year old daughter is an active observer and participant in their fornication. She ponders though how mother and father had seemed sexually aroused by their babygirl's underpants and how Yumi had tasted Samuel's semen suggesting more than a hint of an incestuous relationship. Not that Mieko was disgusted by the idea of incest given her own incestuous relationship with her sister as they were growing up. Mieko goes back to her bed and masturbates herself to multiple orgasms as she relives the memories the erotic tableau she has witnessed. Finally she falls asleep exhausted, but not before she realises that her sister has been hiding taboo secrets and kinky sexual desires just as she has.

Incest does not disturb her, after all she has been involved with her own sister, but she is surprised that Keiko and Samuel have involved their little girl in their sex games. And that she seems to enjoy it so much. You would never have imagined that such a young girl could be so sexually stimulated. She must have inherited the family genes or been well taught by her kinky parents.

Mieko wants to be part of the extended family and experience the obvious love and intimacy they share - but she is not sure how to broach the subject and join in the family fun. She now feels she may have found the perfect home where she belongs and would've accepted for her sexual desires, which many would find abhorrent and disgusting. She believes she would not be judged by her sister and brother in law and may even welcome her. Although she still fears raising what she has seen with Keiko as she is unsure how her sister might react at being spied in and that she might be rejected. What she doesn't know is that Keiko had spied her in the mirror as she played voyeur and it excited her to be wanton exhibitionist and put on a show for her sister, squealing loudly as she climaxes with Samuel's cock buried deep inside her and their daughter being an active participant in the marital bed.

The next morning Mieko wakes up late and gets up to have breakfast. She can't see anyone around but then she hears her sister's voice coming from her bedroom. "I am in here Mieko. Sam and Yumi went out to buy some groceries and should back in an hour."

Mieko finds her sister laying in bed under a single sheet, looking at her iPad. She admires the prominent curve of Keiko's tummy and breasts outlined under the sheet. "Come and join me in bed sister so we can chat, it is so long since we shared a bed. Take your nightdress off, no need to be shy here." Keiko lifts the sheet so Mieko can slide under the sheets and she catches a glimpse of her sister's naked body. Mieko raises her nighty over her head and climbs under the sheet naked.

As Mieko climbs into bed Keiko puts her iPad aside and Her sister notices she had been reading a webpage called Leslita. She wasn't sure what that was but she filed it in the back of her mind so she could check it out later - it sounded very interesting. "You look luminous, sister" Mieko says. "I feel like I am the size of a house", she says chuckling and rubbing her belly. She notices Mieko gazing at her, "Don't be shy sister, you can touch it if you want." Mieko strokes her sisters tummy and is thrilled when she feels one of the twins kick.

Keiko's face turns a serious, "Mieko you know I love you absolutely ..... is there something you want to tell me? I feel there is something you are keeping inside. I won't judge or criticise you, I just want you to be as happy as I am. Sam and Yumi have made my life full but it will never be complete until you as a permanent part of my life again."

When Mieko pauses Keiko goes on,"after all you have seen my own deepest secrets laid bare." Keiko sees a flash of confusion cross her sister's face, "I saw you looking through our window last night while Sam and I were making love. Don't worry I didn't mind, in fact it made the sex even more exciting knowing we had our own personal voyeur - or really two voyeurs if you count Yumi. It also it makes it easier as I don't need to explain about Sam, Yumi and I."

"You know now that Yumi shares our bed and we don't hide our fucking from her. She is fully a part of our life and love. I have also helped my little girl learn how to give herself pleasure. You should see her when she masturbates, she is so adorable. The three of us are very happy together - but we have room for one more. I spoke to Sam last night after you had gone back to your room and he fully agreed that we would love if you came to live permanently with us. I told him on our wedding night about our childhood sexual experimentation and he has always been very accepting of that. In fact I suspect the thought of us as little girls making love turns him on. He seems to fuck me twice as hard when I call him daddy in bed. We discussed it last night in bed and agreed we would love for you to join our kinky household. Sam knows how much I love you and am in love with you. We also noticed how Yumi took to you immediately. I think the saucy minx was actually trying to seduce you last night with that lingering goodnight kiss. Although I am sure she didn't realise what she was doing, or what affect she was having on you. I did notice though how hard your nipples were and the blush that spread across your face when she finished kissing you."

Mieko weeps with relief and happiness, knowing that her sister wants her as a permanent part of her life and that she has somewhere she can call home. She embraces her sister and buries her face in her neck. After a while Keiko raises her her sister's face and kisses her. What starts as a chaste kiss soon grows in heat until the two are kissing open-mouthed, tongues entwined. The thin sheet slips down and the sister's breasts rub against each other. Mieko feels a dampness on her chest and realises that Keiko's lactating breasts are leaking milk all over her. She pulls back to watch the milk dripping from Keiko's nipples. She smile at Mieko, "it is ok my darling sister, would you like to drink my milk too? Yumi and Sam both love nursing and often I have one on each teat. I would love to have you suckle on me too, just like a little baby."

Mieko doesn't need to be invited twice. She quickly attaches to Keiko breast and hungrily sucks on the turgid nipple. She mews with pleasure as her sister's breastmilk spurts into her mouth and she gulps it down. She nurses quietly, rubbing Keiko's huge pregnant tummy while her sister whispers words of endearment in her ear. When she empties one tit, she moves to other and repeats her sucking. The fingers of one hand drift between her legs to stroke her own sex gently while she drinks.

When she has emptied the second breast, Mieko makes an exaggerated gesture, licking her lips noisily. "Mmmmm my darling sister, that was yummy. I can understand now why Yumi doesn't want to wean herself off her mummy's teat. Not only is your milk delicious but I love the intimacy that comes with nursing on your breast. What a special time for mother and daughter, no wonder you have been doing it for seven years now. Your nipples are so long and fat, they are amazing."

Keiko giggles, "Sometimes I feel like a cow, with two hungry mouths chewing on my udders come milking time. Now it will be three and soon five. I am not sure I will have enough to go around! Anyway enough of this, I think it is time you tell me what secrets you have been keeping from me, after all you now know all my secrets."

Mieko turns serious and slowly tells her sister the truth of what has happened over the past few years. She explains her deep attraction to little girls, the scandal when she was teaching and her firing and then finding it necessary to turn to fetish modelling. She details her career as a dominatrix playing with her saucy submissives, then finally the reason why she had to flee Japan after being blackmailed by some incriminating photos. She finishes by complaining "all these dramas and I still have never touched or seduced a little girl - if you don't count our childhood intimacies - although I have spent many hours dreaming of doing it."

Keiko listens quietly till Mieko finishes her story and then asks a few questions. Finally she smiles sweetly, "No need to feel embarrassed sister, it seems we share a love of little girls. I didn't admit to myself until Yumi was about six that I had sexual as well as maternal feelings for her. It was very confusing and confronting. I confessed my feelings to Sam as we share everything. He was so supportive and made me feel it was a normal emotional connection."

Keiko picks up her discarded iPad, "I found a website called Leslita where I could read many erotic stories about woman and little girls, which only inflamed my desires even more. I made a number of online friends who I could share these perverted desires with anonymously, it is so liberating to be able to share those sexual fantasies with like minded women. Some who are mothers, aunts, or sisters with incestuous fantasies. Or other who are schoolteachers like you were, or librarians, coaches who enjoy the company of young girls. Some of my best friends have even shared photos of themselves with the objects of their desires. Here come and look at some of the photos on the iPad." Keiko shows her sister photos of smiling women with beautiful children. Many are family holiday snapshots, while others have been taken at home. Some couples are obviously related from their physical resemblances, mother/daughter, grandmother/granddaughter, siblings. The common thread of the photos is the joy and closeness they women and the girls share. In some they are fully clothed, in others in their underwear, and them there are a few where they are naked in the bath, on the nudist beach or in the bedroom. Some are explicit shots of intergenerational couples or threesome or small groups engaged in lesbian sexual activities. One series of shots shows a mother, father and 11 and 16 year old daughters in very intimate sexual activities. As they flick through the photos the sisters are stroking their slits.

Keiko places the iPad aside, "Since I told Sam about my deepest desires and we have been reading the erotic stories and corresponding with like-minded people, we have made a pact to encourage Yumi to be open with us. We have been totally open with her about the sexual and emotional love that a husband and wife share. One day when the three of us were hiking in the woods we had a game-changing experience which prompted a removal of some barriers we had kept with her. More recently we have been including her in our sex play and letting her watch us make love and learn about her own body and what feels good. While Sam and I would love to involve her even more her in our sex play we don't push and will let her discover and experience new things at her own pace and when she is comfortable. She is as sexually curious and precocious as we were at her age so I don't find it unusual. I want Yumi to have an even better sexual education than we did when we were kids. And our experiences growing up were precious, Sam and I would love to share this exploration with Yumi, and now with you too." She pauses, a broad smile now lighting up her beautiful face and a naughty glint in her eye, "Enough of this sex talk sister, it is making me horny. Why don't you show me how much you still love me?"

Mieko removes the sheet that is covering them. She admires her sister's pregnant body marvelling at how huge her tummy is. She kisses down her body, all over her belly till she moves down so she is laying on her tummy between Keiko's legs. From that position she can't see over her belly to see Keiko's face but as her sister lifts her knees up and parts her legs she knows what she wants from her. This was a position they had enjoyed as young girls. Mieko licks her lips as she looks at her sister's perfectly hairless vulva. "Mmmmm my darling what a gorgeous babycunt you have, it is flawless, with the plumpest labia, so delicious," she says as she kisses up Keiko's inner thighs from her knees till she is almost at her sex. She inhales her sister's musky scent.

"I am glad you like it sister, I had the hair removed so that I could be like we were when we were little girls. My husband and daughter like me like that as well. But I cannot claim to have the prettiest cunt in the house. Yumi wins that prize hands down, it is so soft, smooth, and perfectly shaped, never having had a hair on it. I have to admit it is so tempting, many times I have wanted to plant a kiss right on her hairless mound. So far I have controlled myself."

Keiko looks over Mieko's naked body and notices that she sports a lush bush covering her mound as well a thick covering in her armpits. "You look beautiful and sexy too, and I want to inhale your musky womanly scent" Keiko says. Mieko places her hands high on Keiko's inner thighs and parts them further enjoying the sight of her sister's outer labia opening to show the wet and pink inner lips and her vaginal opening, glistening with her wetness. She presses her lips against her sister's temple of Venus. Then her tongue slips out of her mouth to slowly lick along Keiko's slit, dipping inside her cunt and then swirling around her stiff clitoris. She laps enthusiastically, enjoying the sounds of pleasure coming from Keiko, which reaches a crescendo when she orgasms.

They then lay side by side on her bed, head to foot in a 69 position, their heads buried between the others' legs licking furiously. It is at this moment that Yumi and Samuel return to the bedroom from their trip and find them in bed together making love. Samuel clears his throat to let them know they are there, although not until he and Yumi have stood there for a few minutes taking in the erotic scene.

The twins look up from their mutual cunnilingus, their faces covered in each others' juices and smile at the looks on Yumi and Sam's faces. Keiko is the first to respond. "Why don't you take off your clothes babygirl and join mummy and aunty here in bed. We have been talking about you and Aunty is going to come and share our bed. Wont that be fun, all four of us together. We can even play new sexy games together - just like mummy and Aunty used to do when we were little girls just like you. Would you like to join us and watch up close how two women pleasure each other?" Keiko looks to Samuel for his approval and he nods his head in reply.

Yumi pouts at her mother and whines, "mummy why do I just have to watch. I am a big girl now. Why can't I do the things you and Aunty were just doing. You know .... kissing each other's coochies. Why should you have all the fun. I want to do sex things too."

"I know you are a big girl now princess, but to me you will always be mummy's little girl. I know you have been so good when mummy and daddy have sex together. And you know how much we want to have you join us in these games but you are still so young. We don't want to do anything to hurt you. You have heard us talking dirty in bed and I know it is confusing sometimes between what is fantasy and what is reality. When mummy teases daddy about how depraved he is for wanting to fuck his beautiful daughter, that is just playing. Like when I pretend he is my daddy too when he fucks me. She how big his penis is, it is ten inches and very thick, it is too big for a little girl like you to take inside you. But i know you are very precocious so maybe it is time for us to show you some new games. So get naked and come into bed with Aunty and me." Before Yumi can move Mieko jumps up off the bed, "let me help you undress princess". Keiko and Sam laugh at her obvious eagerness to get Yumi naked. The horny woman pulls Yumi's sun dress over her head, leaving her clad in just a pair of thin panties. The tight knickers clearly outline her prominent mons and deep cleft and the crack of her bum where the panties have slipped inside.

Mieko mesmerised by Yumi's sweet innocence can feel herself falling in love (and lust) with her niece just as she had with her own sister. She hugs Yumi close against her naked body feeling the coolness of the girl's skin against hers. She pulls Yumi's underpants down, loving the thrill as her bald mound comes into view then the thin lips of her cunt. She realises that Keiko was right, Yumi does have the prettiest babycunt she has ever seen. As the sweet seven year old steps out of her panties Mieko remembers what she had seen Keiko and Samuel do last night. She raises Yumi's underpants to her nose and inhales deeply, savouring the sweet, clean scent of her niece's cunt which permeates the cotton.

Mieko is about to discard Yumi's panties when the little girl grabs them from her hand and scampers over to the comfy chair in the corner of the room where her daddy is sitting. Samuel has quickly discarded his own shirt and t-shirt and is sitting naked, his enormous erection standing up straight and proud. "Here daddy these are for you," she says handing him the small ball of cotton. "Thank you princess, what a considerate girl you are. You know how much daddy treasures your used panties" he says feeling the warmth of the material and raising the cotton panties to sniff them. "You smell so delicious babygirl. Daddy loves you so much." "I love you too daddy." she says moving between his legs to give him a cuddle and feeling his stiff cock pressing against her tummy. "You be a good girl for mummy and Aunty Mieko and have fun. I'm sure they will teach you lots of new fun things. Daddy will just sit here and watch for now."

He hugs her closer and kisses her on the lips, at first a gentle touching of lips which soon turns into a more passionate French kiss. His hands squeezing her bottom as he enjoys feeling his cock rub against her belly. He breaks contact though before he shoots his semen all over his daughter again. Not wanting to embarrass himself in front of his sister in law or to give his lovely wife another example to tease him with. "I'll keep these here, "he says holding up her panties, "they will come in handy" he smiles as he rubs the cloth along the length of his erection. Mieko says 'you two seem to have a real fetish for Yumi's cute panties. I have seen both of you sniffing and tasting them."

The girl pauses on the way back to the bed, she sees her mother's and aunty's panties on the floor. She picks them up and takes them to her daddy. He sniffs both pairs and offers them to Yumi to sniff too. While Yumi has her nose buried in her Aunt Mieko's knickers, Samuel lifts his bum off the chair and slides Keiko's pink panties on, his cock barely contained in the material.

"You look so pretty in mummy's panties, daddy."

"Thank you princess," Samuel says kissing his daughter on the forehead. When Keiko sees Mieko looking at her quizzically she whispers in her sister's ear "Sam is my adorable little pantyboy sometimes. He loves wearing my panties, the more feminine they are the more he likes them. He has been a pantyboy since he was a young boy and developed an unhealthy interest in his mother and sister's panties and discovered how horny it made him when he tried them on. Sometimes he just likes being one of the girls." She giggles.

Yumi and Mieko walk hand in hand naked to the bed and climb up to join Keiko.

Yumi snuggles between the two women. She kisses her mother on the lips then her Aunty. Two pairs of adult hands glide over Yumi's thin body, causing the little girl's body to tremble as they caress her flat chest and nipples, fondle her soft bum and rub between her legs.

Yumi's fingers reach out to fondle Mieko's breasts. "Mummy, Aunty has smaller boobies than yours, bur they are really nice too."

"Well princess she hasn't nursed a baby ... or a big girl ... like you. When we were younger our boobies were identical. Would you like to kiss Aunty's boobies like you kiss mine? I am sure she would love that."

Yumi snuggles in closer and tentatively kisses Mieko's tits. When the woman moans in response and puts her hand on the back of Yumi's head to pull her in closer, the little girl becomes more confident and begins to lick and suck the stiff nipples.

"Oh god ... yes .... Yumi you are wonderful .... please keep sucking on my nipples ... you are turning Aunty on." Mieko looks down at little Yumi sucking on her tits as she gently rubs her niece's tiny bottom. She is heaven, living out her most perverted fantasies. She knows deep in her heart that she will never be able to leave and will spend all her life here with her family.

Keiko interrupts, "Did you see mummy and aunty licking each other between the legs, babygirl? Would you like mummy to lick your cunny too like that I am sure Aunty would like to taste you too? We have never done that before and it will tickle your coochie really nicely. Mummy and Aunty used to play that naughty game all the time when we were little." "Yes I saw mummy. It looked like fun. Aunty has a lot of hair on her coochie, not smooth like you and me. Please kiss my peepee mummy." Mieko wants to be part of this experience so she lays back at the head of the bed and opens her legs. Yumi sits between her legs, her back pressing against her Aunty's small breasts her bum pressed against the woman's sex. The girl giggles as she feel her Aunt's pubic hair tickling her bottom. Mieko gently caresses Yumi's flat chest, feeling the small nipples harden and her breathing deepen. She props the girl up so she is now straddling her own spread thighs,

In that position it is easier for Keiko to access her daughter's cunt as it is difficult with her pregnant belly for the mother to get too low down. Mieko's hands trace down over Yumi's chest and across her tummy. Eventually her hands find their way to the little girl's inner thighs which she caresses softly and then uses her hands to spread the seven year olds legs wide, lewdly opening up her vulva to her mother's gaze. Keiko's face is up close, only inches from her daughter's hairless cunt.

She hears a voice, her sister's, as Mieko's fingers part Yumi's plump labia, "what a pretty vulva your daughter has, sister. Are you really going to lick your own daughter's cunt? What a perverted mummy you are. You always were a sexy slut as a child and now your baby girl is going to grow up to be just like her mummy." Mieko's dirty talk inflames Keiko's desires and she begins to lick up her daughter's inner thigh. First one then the other, slowly and deliberately, stopping just before she reaches her slit. Yumi begins to thrust her bottom off Mieko's lap, pleading with her mother, "please mummy lick me here" she points at her sex, "it feels so wet and itchy."

She can't deny her beautiful daughter's wishes any longer and bends her head down and traces her tongue along the full length of Yumi's labia, from bottom to the top and back again. She repeats this several times before using her thumbs on each side of her daughter's sex to part her precious flower and open her up. Keiko gazes lustily at her daughter's exposed vagina before pressing her tongue between her labia and beginning to lap at her cunt. The sweet taste is everything she had hoped it would be from sucking on Yumi's soiled panties. The little pixie squirms and moans as her mother's tongue stimulates her preteen slit. Keiko's head is spinning as she knows she is finally doing what she has desired since Yumi was a toddler. She hears faint clicking in the background and it registers at the back of her mind that it is probably Sam recording this wonderful moment with camera and video, so they can look back at the first time she performed oral sex on their daughter, her face between Yumi's legs and her bum in the air, her big belly pressing against the bed. Keiko feels soft hands on her bum at that moment and knows it must be Sam. She feels her bum cheeks being parted and then a wet tongue licking at her tight arsehole and fingers stroking her slit. Her body shakes with a shattering climax as she has her tongue in her daughter's cunt and her husband has his tongue buried in her arse. She collapses to the side spent and sees Mieko quickly take her place between Yumi's thighs and begin to lap hungrily at her little niece's sex. From the sounds she is making, her sister also loves the taste of a little girl's cunt as much as she does - and she has to admit her daughter does taste delicious. When Mieko finally lifts her face from between Yumi's legs, she is smiling broadly and her face is covered in the girl's juices.

Keiko looks over to where Sam has gone back to snapping photos, the red light glowing on the video camera on the tripod in the corner. She smiles at her husband and as her gaze trails down his body she notices a big sticky mess in the front of her panties that he is still wearing. Obviously watching his darling wife licking their beautiful daughter's cunt had been too much for him and the horny daddy had ejaculated inside them soaking the material.

"Look at the mess daddy made in mummy's panties, Yumi. I think he should take them off and clean himself up. Perhaps he could replace them with Aunty's knickers, they are so feminine, I am sure he would like wearing them."

Samuel removes the cum soaked panties and all three girls notice the sticky semen covering his cock and balls. He uses the soiled material to clean off his genitals. Then he picks up Mieko's worn knickers and after looking at her to see if she approves he slips the lavender panties on, a cute little bow on the waistband and lace around the edges.

They all pause catch their breath overcome by the sexual debauchery and their shared orgasms.

Yumi breaks the long silence "Mummy that felt so good, I thought my coochie was going to explode when you were licking it. Can I kiss your peepee now?"

"Oh yes babygirl, mummy would like that a lot. I am quivering with anticipation."

Mieko cuddles Yumi to her side "would you like Aunty to teach you how to lick mummy's cunt?"

"Yes please Aunty."

"Ok sister open your legs for your little girl."

Keiko sits at the top of the bed, a pillow under her bum, her knees up and legs spread, her labia pink and engorged from the stimulation it has already had. Mieko leads Yumi between her mother's legs, their two heads side-by-side close to Keiko's vulva. The horny mother is so aroused exposing her sex so wantonly to her sister and daughter. Mieko joins Yumi between her mothers legs and explains the different parts of her vagina to her. She suggests the little girl gently stroke her mother's labia. Yumi reaches out with her finger and tentatively touches the slit then letting her finger glide between the lips of her sex. Keiko groans as Yumi plays with her cunt. Mieko reaches in to part her sister's outer labia and showing Yumi where the clitoris is. Soon the little minx is rubbing the stiff clitoris and enjoying the effect she is having on her mummy. Then her Aunty encourages the girl to use her lips and tongue while sliding her fingers into her mother's vagina. She licks her slit slowly, then pausing to taste the tangy secretions. When she determines she likes the taste Yumi gains confidence and picks up speed on her mother's genitals. She pushes one then two tiny fingers inside her mother, feeling the hot wetness inside her vagina. Keiko feels her tummy muscles tighten as her daughter's fingers probe deeper into her slippery sex.

Keiko is propped up on some pillows so she can observe her little angel licking her over her prominent tummy.

She tries to relax her cunt muscles, and as she does so, the fingers slide deeper, And her tiny thumb brushes against her mummy's hard clitoris and it sends her over the edge, her cunt spasms and squeezes Yumi's fingers. As her body trembles she squeals and squirts some fluid over her daughter's hand as she experiences a sharp orgasm. Her thighs squeeze around Yumi's head. "Fuck .... fuck .... fuck ..... fuck mummy with your fingers. I am such a horny slut. Oh god baby you are going to make mummy cum. What a good lil cuntlicker you are. Aaaaiiieeeeee." Keiko is panting in a post-orgasmal bliss. Yumi cuddles into her mother, a large smile on her face as she is proud of herself. Keiko kisses Yumi and tastes her own juices on the girl's soft lips. The two women and little girl snuggle together and then Samuel joins them on the bed.

As all four snuggle together, with Yumi between the two women and Samuel pressed against his wife's back, Mieko releases that to be fully a part of this ménage a quatres she must also bond sexually with her brother-in-law. he has shared his family with her and she must share herself with him.

To break the ice she says "it seems there are two virgins in this bed, but it probably time for one of us to be deflowered." When she sees Yumi's face light up she laughs, "Don't look so exited Yumi, I didn't mean you, you're still to young to be your daddy's lover. I meant me. I am certainly old enough and I have never been with a man as I prefer women, and little girls, but your daddy is as dear to me as any man I have ever known. I see how happy he makes you and your mummy. If we are going to be a happy family then I think it is time we became intimately acquainted. From what I have seethe is a skilled lover and I am sure he will make my first time very pleasurable - just as he will with you Yumi when it is your time to lose your virginity." Keiko smiles "I think that would be lovely. I agree we should all be close and open with each other if we are going to be a happy family. I am sure if you want a good hard fucking Sam would be willing to help out, he has admitted to me that he has had the hots for you since we first met. He also has a fantasy of fucking twins and I think a threesome would be hot. Look at how hard is cock is now, he is certainly stretching those pretty lavender panties of yours. Plus when I have these babies he will need a sexy surrogate to take my place, he is a horny man with strong desires. I think, most importantly, he will make your first time a very enjoyable one. When you have consummated your bond with him we will truly be a family." Samuel moves across to kiss Mieko tenderly on the lips, his hands gently fondling her small breasts and exploring her lithe body.. He looks into her eyes "I have wanted to be intimate with you for so long Mieko. You are my sister, Keiko's sister and lover, and now my Yumi's lover. I would love to slide my cock inside you and be your first, as I was with Keiko and maybe, if she wants it, Yumi's first too. But are you really sure this is what you want sister? You shouldn't feel obliged, as far as I am concerned, you are fully a part of this family now and we will all love you just as much whether we have intercourse or not."

In response Mieko silently lays back and spreads her legs a tear of love and emotion in her eye, "fuck me brother, i love you too and want our love to be consecrated before your wife and daughter. From this day and on we are brother and sister as if we were blood."

Sam raises up on his knees his huge erection stretches the girly panties he is wearing. Keiko turns to Yumi and whispers in her ear, then she says to Samuel "let our little girl help you deflower my sister. Look how excited she is, her eyes are gleaming."

Yumi goes to her father and reaches to the waistband of the panties and pulls them down, releasing his massive erection which immediately springs to attention. She wraps her small fingers around his throbbing penis and caresses it gently. She seems to enjoy the thrill of having her daddy's cock in her hands. Keiko reprimands her daughter, "don't play with daddy's penis princess this is Aunty's time."

Yumi looks disappointed as she was having fun, but she helps to guide Sam's cock to the entrance of Mieko's vagina. She rubs the head of her daddy's cock along her slit and watches transfixed as he pushes forward and his large prick slides inside her cunt. Mieko wraps her legs around Sam's waist and her arms around him, they kiss as he slides his cock deeper inside her until he reaches a barrier. He again looks into her eyes, and when she nods her head he pushes through her hymen and fully penetrating her. His full ten inches is soon buried in the tight sheath of Mieko's cunt. They pause before beginning a slow and steady fucking motion. Keiko is hugging Yumi to her while they watch the two lovers mating. It is not long before Sam moans deep in his throat and he starts to pull out of Mieko but she pulls him in tighter and says, "please cum inside me ... fill me with your seed brother." Samuel thrusts deeply and ejaculates deep inside his sister's womb as the walls of her vagina spasms around his penis.

The four kiss and snuggle talking about their shared experiences that night. Yumi drifts off to sleep first as the three adults talk about plans for the future until finally they all fall asleep in a jumble of arms and legs.

The next morning Samuel wakes in a sleepy haze, a pleasurable feeling between his legs. In his groggy state he realises it is Keiko gently sucking on his cock and he gives in to the pleasurable sensation. As he slowly regains his senses, the sleep haze clearing, he notices her sucking is a little different to normal, slower and more tentative. Just as he is processing this he hears a soft seductive voice in his ear "Do you like that baby?" Confused he slowly opens his eyes and looks directly into his beautiful wife's eyes. He sleep muddled mind realises something is not right as he feels his cock still encased in its warm, wet confines. Then his mind kicks in to gear and her realises it must be Mieko sucking his penis. He smiles inwardly at the thought remembering the delicious lovemaking he had shared with his sister the night before.

He gazes down over his belly expecting to see his sexy sister-in-law giving him a morning blowjob but his eyes widen as he takes in the shocking sight before him. His gorgeous 7yr old daughter is laying naked on her tummy her face between his thighs, lovingly licking and sucking on his cock. She hears her mother's voice and then her daddy's guttural moan and her eyes tilt up till she is staring into his eyes, her mouth filled with about half the length of his cock, which is all her tiny mouth seems able to accommodate. She then slides the hard shaft between her soft lips one tiny hand cupping his replenished balls hanging heavy between his legs - as she has often watched her mother do. He feels his thick cock throb in his babygirl's mouth. He moans through gritted teeth wanting to savour the sensation of being sucked off by his little girl and delay his ejaculation for as long as he can. But before long he can control no longer as he feels an ache in his balls.

"Daddy is going to cum" he warns his daughter, a split second before his semen surges from his testicles, through his shaft and spurts copious amounts of hot semen into Yumi's willing mouth. The little girl has learned well from watching her mummy sucking her daddy's cock many times and she swallows as much of the hot cum she can, although some spills out to cover her chin and chest.

Keiko smiles seductively at her husband "what a beautiful girl we have honey, it looks like she is a natural born cocksucker just as she is a natural cunt licker." Samuel is still transfixed as he watches his daughter with her delicate fingers circling his penis as she licks his cock clean. She smiles her angelic smile as she is so proud of herself. Keiko moves down to praise her daughter's cocksucking skill and kisses her on the mouth tasting her husband's cum on her daughter's lips, before dipping her head to lick a few stray splashes of semen off Yumi's flat chest.

Yumi has been wanting to suck her daddy's cock for some time, since the first time she saw her mother giving him oral pleasure. She has been jealously watching mummy suck daddy's cock almost daily for the past months, sucking him in bed, in the shower, in the living room, the kitchen, and even when they had been at the cinema.

She has been watching jealously and waiting to be invited. Her mummy had told her no one should touch anyone until they are invited. This morning when she woke up in bed snuggled with her parents and Aunty Mieko and saw his flaccid penis laying against his stomach, thoughts of last nights debauchery still clear in her mind, she could wait no longer. She had been so disappointed last night when she had been playing with her daddy's cock but her mummy had made her stop so he could put inside her Aunty's hairy 'gina? The little girl still couldn't accept that she was too young for her daddy to put his penis inside her vagina. She wanted to be daddy's girl just like mummy was ... and now as Aunty was. But she knew she would have to wait until they thought she was ready.

She had decided she wouldn't be denied the pleasure of at least playing with his penis again. She wrapped her tiny fingers around her daddy's prick and began to stroke him, trying not to wake him. As his prick stiffened Yumi noticed the clear liquid leaking from the end of his cock, she licked the precum off the tip of his cock. With two hands she slid them up and down the shaft of his erection while her lips nursed on the rubbery head of his cock.

She felt a stirring beside her and glanced up to see her mother staring at her lovingly. She felt anxious as she has been caught doing something naughty but Keiko just smiled and says,"Mmmmm daddy's cock tastes good doesn't it sweetie? Don't worry you aren't in trouble, I will just lay here and watch you sucking his dick. You both deserve that reward after the fun you had with me and Auntie Mieko last night. I can give you tips if you need them." Keiko slid down the bed so she could also watch Yumi sucking Samuel's now stiff penis, she rubbed her hand along her daughter's back until she reached her small bum, rubbing the cheeks before her fingers drifted between Yumi's legs to caress her hairless vulva.

It was about this time that Samuel had stirred from his sleep to enjoy his incestuous fellatio.

As the three snuggle together in a post-fellatio bliss they notice Mieko is also awake now and has been watching them. "that was so precious, watching my adorable little neice sucking her daddy's cock. Was that your first time Princess?" Yumi nods shyly, "Yes Aunty but I have been wanting to do it for a long time now."

"Well it looked like you did a good job, your daddy certainly seemed to enjoy it!" she giggles. "You really are a big girl now. I'm much older than you and I have never sucked a penis. but I am sure I will get a chance soon."

Little Yumi giggles and says "we were three yesterday and now we are four. We are going to be a very happy family."

Keiko says "what an intelligent girl you are princess, we are going to be happy foursome."
