Lisa decides to scan herself, once she is scanned the 10-year-old opens the transformation options and scrolls through the list, her eyes landing on the option “unbirth”, ‘I wonder what that is,’ Lisa thinks to herself and decides to read the description:
“Unbirth a chosen target and make it your child,” it simply states.
A grin forms on Lisa’s face, working quickly, Lisa selects the option, then she is asked to select a target that should become unbirthed, selecting Jeff, finally she is asked to select the “mother”, her grin widens when she selects herself, before confirming the change, deciding it’ll be more fun if Jeff would be aware and the reality wouldn’t alter.
After feeling the tingling sensation, which indicates that the change is about to happen, Lisa quickly strips out of her clothes and sits down on Jeff’s bed, her legs spread, feeling a mixture of excitement, curiosity and fear rise in her as she waits for Jeff.
It doesn’t take long for Lisa to hear the heavy footsteps of Jeff and shortly after her big brother enters the room, a confused look in his eyes, which grows into a mixture of shock and confusion.
“Lisa,” Jeff asks, “what the hell? Why are you in my room… naked? And… and why do I feel so weirdly drawn to you?”
Lisa grins, “you’ll see soon enough, dear brother,” she says.
Jeff opens his mouth to respond, but is shocked when he feels his arms move on their own, slowly lifting his shirt, taking it off and throwing it to the floor, before his feet kick off his slippers as his hands then move to his jeans. The teen tries to stop himself, but is unable to, and can only watch in horror as his own body betrays him, soon the teen is totally naked, standing before his naked 10-year-old sister.
“Lisa,” Jeff says, his fear growing as he finds himself slowly walking towards his sister, who is sat on his bed, her back against the wall, “what is… going on!?”
Lisa just giggles, feeling more excited than scared.
Jeff tries with all his willpower to stop himself, but no matter how hard he tries, the teen just is unable to get control over his own body back. The teen can only just watch helplessly as his body climbs on the bed, crawling over to his sister, placing his hands on her legs before spreading them apart.
Lisa grins wide, enjoying the fear in her brother’s eyes and on his face.
Once Lisa’s legs are spread wide enough to expose her hairless pussy, Jeff’s eyes widen even more as he finds himself lean forward, his face inching closer and closer to Lisa’s sex, the fear inside Jeff is so extreme, that the 16-year-old is unable to find words.
Jeff is horrified when his nose begins pressing against Lisa’s pussy, slowly penetrating it, the 10-year-old lets out a giggle.
“Jeff… you nose is tickling me,” Lisa says, spreading her legs a little more, luckily the girl is flexible thanks to her gymnastics.
Jeff is about to reply, but his mouth is already pushing into Lisa, her pussy beginning to stretch, and he can hear his sister letting out a moan.
Whatever is happening, Jeff knows he doesn’t like it one bit, and continues to try getting control back over himself, though he knows it’s no use, as he can feel his face, his head, pushing further into Lisa, her pussy stretching like some elastic material around his face and head, the moans of his 10-year-old sister seeming to increase in volume, the little girl starting to even pant and take deep breaths, as Jeff feels her body relaxing, making it so much easier for his body to enter her tiny body.
Jeff’s vision turns black as his eyes follow the rest of his face into Lisa, soon the moans of his sister become muffled as his ears slip into her body, then suddenly, and to his horror, he feels his entire head pop into Lisa, who lets out a loud moaning gasp. The teen is horrified and surprised that he is still able to breath, his fear rising once more as he feels himself continuing to slip into his sister’s body, the teen feeling as his shoulders begin to enter her.
Lisa pants and moans, grinning down at the huge bulge in her tummy, her brother’s head, feeling it pop into her womb. The 10-year-old lies a hand on the bulge and strokes it, “wow, I’m… surprised that… he actually fits inside of me,” she says to herself, “my body feels… so elastic, it feels so good. Hehe, my tummy will be huge, once he is fully inside of me! I’m gonna look sooooo… weird!”
Over the course of four hours, Jeff’s body continues to enter Lisa, soon Jeff is completely inside of the little girl, curled up in her womb.
Lisa is lying on her back, on Jeff’s bed, panting hard and sweating, grinning up at the ceiling, she then feels her tummy begin to shrink, her grin widening, ‘soon Jeff will be nothing than a cute little ovulum,’ she thinks to herself, ‘then all I need is a handsome boy to fertilze IT! Hehe… I’m gonna be the mommy of my stupid brother!’
Inside of Lisa, Jeff feels disoriented, the teen is unsure of where he is, that is until he feels something attach itself to his belly button, his eyes widen in horror, ‘n-no… no, please… d-don’t tell me… oh, god… no,’ he thinks to himself as he realizes what has attached itself to him: an umbilical cord!
Jeff tries to move, but it’s so cramped and tight inside of his sister, that he is unable to move even an inch. The teen then suddenly feels the umbilical cord to do a sucking motion and the more this sensation happens, Jeff begins feeling himself shrink and become younger, ‘wh-what is she… doing to me,’ he thinks to himself in fear. Jeff then notices something weird happening to his mind, ‘wh-what was my name again,’ he asks himself, ‘wh-why do… I feel so… dumb? My… my mind… feels… so empty’. As Jeff continues to grow younger, more and more of his memories vanish, soon the fetus feels confused as to why it felt so scared, and as it continues to become younger and younger, that confusion also vanishes, replaced by total calmness as the embryo becomes nothing than a ovulum. The umbilical cord retreats, its “job” done, leaving behind the tiny egg-cell, waiting patiently to be fertilized by some male’s sperm.
Lisa, her tummy back to normal, sits up on Jeff’s bed, grinning down at herself, lying a hand on her tummy, “welcome home,” she says, “don’t you worry, little ovulum, mommy will find the right man to be your daddy,” with that, the 10-year-old climbs from the bed and puts her clothes back on. She then turns with a smile towards Jeff’s laptop, “better transfer the program onto my phone,” she says to herself, “I don’t want anyone knowing about it and what has happened. Once I have transferred the program over to my phone, I’ll focus on finding the right husband for myself and father for my child!”
