The room looked familiar, but the decor was unrecognizable. A pink plastic chandelier hung from the ceiling, and a couple of old movie posters were taped onto the wall behind the bed. Greg looked to the left, noticing an old antique bedside table that he recognized from his highschool years. His mother had put it in his room and there it was, topped with a brand new purple table lamp. The bedsheets were crisp and white, with a pink damask ruffle along the bottom edge. The comforter was white and pink with a flower pattern, and the curtains on the far side of the room were a sheir rose colour.
Greg rubbed his eyes and looked around the room. It was clearly his childhood bedroom, but it was decorated as if a girl had taken over. He looked down and noticed his hands were not his own. They were slim and delicate, clearly feminine with long french manicured nails with tiny blue flower decals. Greg jumped out of bed and raced to the vanity mirror. He looked at his reflection and was shocked to find that his greatest fantasy had come true. He was a girl.
His features, though familiar and similar to his own, were feminine and beautiful. His hair was light blonde and hung down just past his shoulders. His lips were full and pink, and his eyelashes were long, thick and fluttering, he had perky C-cups, a tiny waist and a round, firm butt. The perfect specimen, his dream body.
“Steph, come on!” His mom shouted from the kitchen. “It’s breakfast time! Hurry up, you’re going to be late for school again!”
It really happened. Greg had been a grown man just one night ago, dreaming of one day getting the chance to relive his highschool days as a beautiful young woman. He had wished and prayed and dreamed for so long, to travel back to this very age, and to be transformed into a girl. It was all just a fantasy, until one night, last night, his prayers were answered. He looked over at the nightstand, and saw the rabbits foot sitting as it had the night before when he went to bed as a man.
Could it be true? He asked himself. He had purchased the rabbit’s foot from an old woman the day before at a strange shop he had never noticed before in town. She had told him that if he held the lucky object his hand and wished with all his might, falling asleep with the rabbits foot next to his bed, that his wildest dreams could become reality. She had been right.
“Stephanie, just pick and outfit! Get down here, you can’t be late again!”
Greg was no more. Now, there was only Stephanie.
Stephanie jumped up and down for a moment, squealing joyfully and revelling in her new, high voice. She called down to her mother that she wasn’t feeling well, and made sure she had the day to become accustomed to her new life and her new, beautiful body.
After a day of adjustment and experimentation, Stephanie tucked herself into bed. She avoided her family as much as possible during her first day in her new life, but was ready to wake up in the morning and go out and experience everything there was to experience as a highschool girl. She fell asleep with a smile on her face, drifting off into a dream that could never compare to the one that had just come true.
Stephanie had no idea what time it was, but her room was dark when she was awakened by a rustling sound coming from the foot of her bed. Her eyes fluttered open, and she slowly began to become aware of her surroundings. She felt something touching her, a strong hand groping and squeezing her thigh. She shook her head to wake herself up, and sat up straight in her bed, startled at the grabbing hand that she felt moving up her leg. Her eyes adjusted to the dim light, and she recognized the face that hovered over her bed.
“Jon, is that you?” She stuttered, rubbing her eyes. “Wow, look at you. Ha, you’re so young.”
“Huh?” Her brother looked confused.
“Oh, uh. Nothing. Forget it. Wait…What are you doing in here? Wh-why are you touching me like that?” Stephanie recoiled a bit as Jon continued to reach under her blanket and fondle her thighs.
“Hmm, well I was sitting in my room watching some girl on girl porn on my laptop and having a little fun, and I realised something. You are in here, all alone, and I was feeling kind of bored with the usual crap I watch. Well, I thought, why not come in here and maybe we can have some fun of our own. You know. Together.” With that, Jon sat on the edge of the bed, and his hand slid all the way under Stephanie’s nightgown until he was rubbing his fingertips against her silky panties.
“Woah!” Stephanie jumped at his touch, and pushed his hand away. “Jon what the fuck is wrong with you! This, this is just…weird.” Her brother chuckled at her reluctance, but his persistence continued.
“Don’t you be shy, I mean you’ve gotten so hot this last year. And I heard you you know, touching yourself earlier today real loud when you knew I was in the next room. It sounded like you were having a great time. Maybe I can make you feel even better.” Jon reached forward again and grabbed a handful of Stephanie’s breast. He squeezed and grabbed at her, crawling toward her on the bed until her back was pressed against the headboard.
Stephanie looked at her brother, younger than she had seen him in so long and awkwardly let him pull her nightgown up to expose her ample breasts. He was young and handsome, with an average body and short brown hair. He looked at her with a wild lust in his eyes, staring down at her perky chest as he breathed heavily. She noticed that his hands were warm and comforting, but something about it all felt wrong. Stephanie had never looked at her brother this way before she had jumped back in time and into this body.
“Jon, seriously stop. This just isn’t right. I mean, what if mom and dad heard us or found out what we were doing? They would freak the fuck out! This has got to be illegal or something, right?” She resisted, recoiling and covering herself. Jon simply grinned and crawled closer until he was straddling her outstretched legs.
“Don’t worry so much, Steph. I won’t tell mom and dad. Maybe you could just have a little taste, that wouldn’t be so bad, huh?” With that, he knelt in front of her, unzipping himself and pulling his girthy member from his pants.
Stephanie couldn’t look away. His cock was so long and thick, and something about the situation made Sephanies newfound womanhood moisten. She felt, for the first time, the tingle of lust in her genitalia. His cock was already leaking precum gushing from the tip and dribbling down onto Stephanie’s smooth legs. The gushing cream looked so appetizing, and Stephanie found herself leaning forward toward her brothers throbbing erection.
She looked up at Jon, his eyes guiding her toward his manhood with a persistent stare. As hesitant as she was, Stephanie couldn’t resist the delectable new experience that stood before her. Something about all of this made her mouth water, and her labia glisten. She couldn’t decide what to do, she knew it was wrong and sick, but soon the decision was made for her. Jon rested his hand on the back of Stephanie’s head and pulled her toward him. With his other hand around his shaft, he forced his engorged tip into her mouth and slid himself down her throat until she was gagging. The sensation was awkward, but intoxicating for Stephanie, and when she got over the choking feeling, she enjoyed the warm meat filling her mouth.
“Oooh, Jesus, Steph! I always knew your mouth would feel so good. I’ve been dreaming of this, yeeeah take it all.” Jon whispered, running his fingers through her hair and thrusting in and out of her mouth. Stephanie let her hands drift up her brother’s thighs, cupping his exposed buttocks and pulling him into her mouth even further.
His thrusts became quicker and deeper, and soon he was moaning loudly as he vigorously fucked his sisters face. She welcomed the enthusiasm, sucking and drooling all over Jon’s thickness. Jon enjoyed his little sisters technique, and decided that this taboo blowjob just wasn’t far enough. He wanted more of her young, tight body. He let out a long groan before pulling his pulsating member from Stephanie’s mouth.
Before she could wipe the saliva from her mouth, he wrapped his strong hands around her ankles and pulled her down the bed. She giggled as her back hit the mattress, and he leaned into her between her legs. He pulled her nightgown up, taking her perky nipple into his mouth as he worked his pants down around his knees. Jon’s hands wandered, exploring her taut, teenage body, and spreading her legs until he was on top of her. Stephanie closed her eyes, letting her brother hold her and fondle her mounds with his probing tongue. She enjoyed the tingling sensations of this taboo experience, until Jon went a little too far.
His hand slipped down to grasp his aching erection, and without warning he leaned into her, his tip invading her moist hole. Stephanie jumped at his forcedullness, and pushed him away.
“Wait! Jon, that’s a little too much. We can’t do something like that. What if you accidentally finish inside me?” As she spoke the words, her loins burned and she felt butterflies in her stomach. The idea of her brother using her brand new body for his taboo pleasures, and cumming inside her, it made her quiver with excitement.
“Don’t you worry,” Jon hovered over her, cupping her face with one hand and leaning in for a passionate kiss. “I promise I’ll pull out and cum all over you. You can trust me Stephanie. After all, we’re family.” Stephanie couldn’t contain her lust, she let Jon explore her mouth with his tongue and take her in any way he wanted. He pushed himself forward once more, and this time his entire cock slid all the way inside her virgin pussy. She gasped at the unfamiliar pressure, and the sensation of his girth stretching her was like nothing she had ever experienced. He thrust deep inside her, filling her completely, and coaxing a series of soft moans from her parted lips.
“Mmm, oh my God! H-how does it feel so damn good!” Stephanie groaned, her fingernails digging into Jons back. He sucked aggressively on her nipples as he fucked her, wrapping his arm around her waist and pulling her close to him. Her back arched, and she tried and failed to stifle her moans of ecstasy. Jon covered her mouth with his free hand, and began to drill her harder as he relished in her enjoyment.
Stephanie remembered how they used to wrestle and horse play when they were young boys, and now that she was a beautiful young woman, this was an entirely new and thrilling relationship. Jon was the perfect size to take her virginity, and the dirty feeling of hiding their forbidden lust from their parents made the experience all the more exhilarating. His hands groped at every inch of her new body, and his mouth and tongue tasted her supple breasts. He hammered into her, his perfect curve massaging her g spot, and her firm body satisfying every filthy fantasy he had.
“God, that tight little body is so amazing! I’m so glad I get to feel you like this!” Jon grunted. “I’ve been dreaming about this for a while. Oooh fuck, you feel so good, so tight!” His fingers wrapped around Stephanie’s toned legs and spread them apart. He pulled her up until she was sitting on his cock, her arms wrapped around his neck and her breasts pressing hard into her brothers face.
Jon leaned back, letting Stephanie ride him. She leaned forward, her breasts hanging over his face as she rocked back and forth and bounced her round ass up and down on his stiff member. She was suddenly in control of the situation, and she loved being on top of her brother. She grinded against him, her clit rubbing against his pelvic bone and his hands squeezing her ass as she bounced on top of him. She rode him faster and faster, her tits bouncing and her body shaking as waves of pleasure crashed over her.
“Oh, shit!” She cried out uncontrollably. Jon pressed his palm to her mouth, stifling her cries of pleasure so as not to alert their parents of their forbidden fun.
“Shhh, keep it down Steph, mom has ears like a hawk, remember? I don’t wanna get cut off before I get to finish!” He released her, and her soft, subtle moans continued as they had before.
“Oh God, Jon…I’ve never felt this good in my life, I want you to be inside me forever, use me, use this body!” Stephanie groaned lowly as she sat back on her brother’s erection. “I want that cock in my pussy every night!”
“Mmm, maybe I don’t just want it in that pussy. I like the look of that round little ass of yours.” Jon smirked up at her. Before she could respond, he grabbed her and pulled her down close to his body. He hugged her close, and turned her over onto her back without ever leaving her inviting hole. When he was on top of her again, he knelt between her legs and slid is cock from her moist cavern.
“Wh-what are you going to do?” Stephanie whimpered, intrigued. Jon rubbed his cock between her glistening pussy lips, moistening his tip before gently pressing it against Stephanie’s puckered ass hole. “Woah! What are you doing?” She reacted in shock.
Stephanie had never experienced anal penetration, not even experimenting when she was still in her former male body. The thought frightened her, though she was intrigued by the proposition. She realized quickly, however, that the choice was not hers to make.
“Don’t worry, sis, you’ll like it. Just make sure you don’t scream too loud.” Jon assured her with a devilish grin. He covered her mouth again, pushing himself inside her without giving her a chance to stop him. Soon, he was stretching her virgin sphincter, and moaning loudly as he penetrated her deep and slow.
Stephanie moaned in both discomfort and pleasure as her brother violated her ass. The sensation was nothing like she had ever felt, and she took every inch of his manhood as he cautiously penetrated her backside.
“Oh baby, doesn’t that feel so good. Mmm your brother filling up that ass, making your little pussy nice and wet. Stretching you out just like you deserve!” Jon teased her, sliding one finger inside her stretched cunt, and rubbing her engorged clit with an eager thumb. Stephanie nodded in agreement, her steady groans never ceasing.
“God, Jon…I had no idea this would feel so fucking good!” She whispered, trying not to get too loud, though the pressure was so intense that she could barely contain herself. “I, I think I’m going to cum soon!”
“Oh shit, Steph!” Jon’s thrusts became deeper, faster, and more erratic as he neared completion. He grunted like a wild animal, and he looked into his sister’s eyes as he came closer and closer. “There it is, there it is, I’m gonna cum inside you!”
Stephanie massaged her own breasts, pinching her nipples and looking down to watch her brother use her body like a blowup doll. Her pussy contracted around Jon’s fingers, squeezing him and nearly pushing him out. His consistent pounding and skilled fingering pushed her over the edge just as he himself released.
“Fuck! Yes! Take it!” Jon cried out, spurting his milky cream into his young sister’s welcoming colon. “Fuuuck!”
“Oh my God! Jon, I’m squirting!” She screamed, spraying her feminine juices all over her brother’s stomach. She convulsed beneath his touch, ecstasy filling her just as he did. She had never felt such pleasure. The sensation of cum gushing out of her ass as Jon pulled his softening cock from her taut hole, the feeling of soaking her own brother in her orgasm, it was mind blowing.
Once Jon had taken his cock out, she felt her sphincter tighten again, and his warm fluid swam inside her. They were both soaked in a concoction of their cum, and Jon collapsed beside Stephanie on the bed. They breathed deep, staring up at the ceiling and inhaling the musty scent of their sex. They stayed as quiet as possible, hoping that their pleasurable screams hadn’t woken their parents.
They looked at each other for a moment, and then Jon rolled off of the bed. He pulled his clothes on, and without a word he walked out of Stephanie’s room. She lay there on her bed alone, sweating and panting, mind racing at what had just happened. She had never thought about her brother in this way when she was growing up as a boy, but knowing that he was so eager to fuck his teenage sister made her start to wonder. Who else in her family would treat her differently, and sexually, because she was now a girl? Who else might want to use her tight, young body to satisfy their filthy sexual needs? What other fun could she have now that she was a woman…
Soon, she would find out.
