Story Tier Prompt for Allornone 

NOTE: This is a June prompt, due to a timezone error when I released the new tier availability. As such, Allornone will get the second part of the prompt this month too.

Rebecca is a brillliant student with plain looks, with dreams of becoming an engineer. Relationships are not on the cards, let alone family planning, but when a jealous student spikes her with a hormonal compound, she finds her mind becoming increasingly occupied with having sex and making babies.

Good Girl, Part 1

Rebecca had always been the 'good girl.' Good behaviour, good work ethic, good grades, good decisions. Her parents and teachers had all said the same thing about her: 'She will go places, a good girl like her.' All her life, that had been the story, to the detriment of many other things, particularly her social life and certainly her romantic life.

In fact, Rebecca showed little concern for her appearance; she was a thin stick of a woman with a flat chest and no curves to speak of, and wild black hair that sprang in all directions. Her eyes were dark, lips thin, and she had a habit of frowning. Lipstick and makeup in general were of no interest to her, and she only wore prim, functional clothing, preferring to focus on nerdy interests, mathematics, science, engineering, and economics, encouraged to follow such hobbies ever since her aptitudes first arose. For her, the future was in occupation and employment, innovation and daring, not base pursuits of sexual pleasure or - God forbid! - making babies.

Still, despite these pressures, Rebecca had prevailed. She had been awarded a prestigious scholarship to St. Barnes University, among the most prestigious education institutes in the world, at the humble age of eighteen. She had enrolled in engineering, and quickly proved to be more capable and brilliant than the rest of her largely male class, able to calculate, problem-solve, and design at a more sophisticated level than any of them. It raised some of their ire, but she quickly learned to deal with it; it was part of being in a mostly-male course, and she got her revenge in test score results and aptitude tests.

This continued for two years, and Rebecca’s rising star was bright indeed, until the fateful day everything changed. The day when one student became so jealous that drastic measures were taken to close the gap between her scores and his. It began when she was sitting alone at the cafeteria, having ordered her coffee, and reading a book on utilitarian philosophy. A student named Mark approached her, looking a little sheepish.

“Hey Rebecca, mind if I sit here?” he said.

Rebecca’s eyes widened. She’d never been asked that before by a man in some time; most knew to stay away from her.

“Um, sure,” she managed, indicating to a seat opposite her. He took the one beside her, flustering the woman somewhat.

“I just want to say congratulations on the test scores Becca,” Mark said, eyes flickering to her test grades beneath her lowered book.

“Oh, thanks. I’m very proud. But there is always room for improvement.”

“Sure, sure. But don’t you ever want to relax? Have some fun. Listen, I’m having a party at my place tonight. Everyone in the class is invited. I organise one every few weeks. You’re welcome to come.”

She pressed her thin lips together. “Thanks, but I’ll have to pass. I need to study.”

“No cutting loose, even for a Friday night?”

“I can’t.”

“You might meet someone. You might die single if you never get out and have fun.”

She almost rolled her eyes, but instead kept her control. Why were people always insinuating she needed to meet someone or have sex with someone or date someone in order to enjoy life? It was neverending!

“I’m sorry, Mark, I just don’t really see myself in a relationship right now. I’ve got a future ahead of me, and dating and all that isn’t really something I see myself doing.”

Mark smirked. “Not the settling down with a family type then?”

She chuckled slightly at the ridiculousness of the notion. “Definitely no. I can’t even imagine being married, let alone a baby. It’s the course that interests me, and future occupation. But again, thanks for the invite.”

Mark shrugged as her coffee was placed at the counter several feet away.

“Ah well, don’t say I didn’t give you the chance. I’ll get your coffee for you.”

She nodded thanks as he retrieved it, but she failed to notice that he slipped in a small sash of white powder that instantly dissolved into the drink. Rebecca had no way of knowing that a brilliant student working in hormone treatments across campus owed him a big favour, and Mark had called it in by asking for something that would make Rebecca a lot more focused on ‘affairs of the body rather than the mind, if you know what I mean.’ He placed the drink before he, the studious woman none the wiser.

“Enjoy,” he said, relishing the moment as she had her first sip. “Oh, and I wouldn’t study too hard if I were you, Rebecca. Something tells me you’ll come around to my type of fun.”

“Unlikely,” she said, giving him a warm but distant smile, “but thanks again, Mark.”

He left with a smile, anticipating what results may come.

Even he couldn’t have predicted how powerful they would be.

Over the next week, Rebecca found it harder and harder to concentrate on her study. Despite a big test coming up soon, she was finding herself constantly flushed and overheated. Her hunger had surged, and she was buying more calorie-filled food in order to sate her gnawing appetite. Some nights were ridiculous; she would consume meat pies and scones and butter-coated toast and roast chicken and ice cream, and would end up lying on her back upon her couch, sweating and straining as her body absorbed its fill.

The gains were becoming obvious. Her previously flat chest had developed some presence, now easily A-cups in size, her bras finally useful for something other than a prerequisite. Her ass had rounded out, and a gentle layer of fat had filled in around her hips. It was disturbing to her, especially since, for the first time in quite some time, she had become stressed enough over her study that she felt the need one night to lie back and masturbate.

It had felt wonderful. It left her wondering why she didn’t do it more often, and that night she dreamed of being penetrated by handsome men, their large dicks thrusting into her waiting wetness, pressing into her passage, and coming hard within her.

***

“Rebecca? Rebecca? Are you even listening?”

The distracted woman snapped to attention, trying to stop thinking about an increasing need within her to copulate with another.

“Hm? Sorry professor?”

Professor Gaarde sighed. It had been the fourth time this week that his star students had not only failed to answer one of his questions, but worse, wasn’t even paying attention! Something had changed in the last couple of weeks: she was dressing less professionally and fluttering her eyelids at the male students. He moved on.

“I was wondering if you could solve the problem on the projection screen?”

Rebecca dropped her pencil, unbelieving that she had been spending so much of her valuable lecture time staring at the hot boys in the theatre room.

“Oh, sorry Professor Gaarde. Well, it’s like this . . .”

She moved up to the board and drew her solution on the board, to the adoration of the professor and jealousy of other students. But as she walked back, she couldn’t help but notice how young Gaarde was, with a wide set of shoulders and athletic frame. Did he work out? Just thinking about him made her nipples harden, and it was only with embarrassed reluctance that she moved back to her seat. She sucked on her pen for the next ten minutes of the lecture, imagining it was something else. It was only when her nipples continued to throb, and her vagina continued to lubricate itself, that she began to feel awkward. She was rubbing her thighs together, trying to calm herself, but that same heat was rising again, and there was an increasing deep-seated need to fill it, stronger than before.

Gaarde continued to lecture, and in her mind he approached her, held her, stripped naked and penetrated her. She had never had sex before, but she swore she could feel it within her, she could imagine it so clearly, and she screwed her eyes close, biting her lip and began to moan. She bucked her hips in her lecture chair, grunting softly as she imagined it. She imagined not just being penetrated, but a man actually coming inside of her, filling her womb. Planting a seed. She licked her lips at the thought of growing something there. Of being impregnated and becoming swollen with another man’s babies. Her groans grew louder, her bucking wilder. It took her far too long to notice the silence.

“Miss Fayland, are you okay?”

She opened her eyes, and the heat was instantly dispelled. What had she beent thinking? The eyes of everyone were upon her, and a group of boys were chuckling as another group of girls whispered among themselves. She rose, blushing so red she might as well have been a stop sign.

“I have to go!” she exclaimed. She rose, trembling and utterly humiliated, and walked quickly to the exit.

Mark, also in the lecture theatre, was trying not to smile too widely. He alone knew what was happening to Rebecca, and was relishing the changes that were already occurring in her body. Despite her attempts to cover up - and even then she was not wearing her form-covering jacket any longer - it was undeniable that her figure had become curvier, particularly her breasts, which had come out of hiding. She had a little cleavage now, and when she walked away, he admired the way her sweet tush jostled from side to side. Oh yes, she was getting a bit of dump in her truck, alright.

“How are you going to end up, Rebecca?” he asked himself.

***

“What’s wrong with me?” the changing woman asked in the mirror. “Why am I changing?”

It had been four days since the utterly shame-filled outburst she’d made in the lecture theatre, and her hormonal state was only getting worse. Her nights were filled with imaginings of being ploughed by men of all colours and ages and kinds, and she was pleasuring herself more and more to cope. It was as if all the years of repressed sexuality had been dammed up within her, and now the dam had broken, and she was flooded with hormonal need. Her degree didn’t seem to matter as much as a good lay at the moment, and even the slightest sight of a nearby male made her nipples stand to attention, and her insides to become moist with passion. Often she would catch herself breathing heavily, overcome with desire, and have to flee back to her apartment.

“I’m not meant to be like this,” she said, trying to fit her breasts into her brassiere. “Why do I suddenly have all these curves - Agh!”

The C-cup bra was painfully tight, her now-large breasts muffin-topping over the tops of the cups. Tears rose in her eyes, and she ripped the bra from her figure, gasping at the sensation of release. Her inflated boobs wobbled on her chest, tugging at her shoulders, and she looked over her form.

“Everything is changing,” she stammered. “I look like a b-bimbo!”

Indeed, she had taken on an increasingly buxom and curvy figure. Her breasts were easily D-cups, if not Double-Ds, and their soreness told her they were still expanding. Still getting bigger. Her waist had become more supple, and her legs seemed smoother, more refined, her thighs thicker. It was undeniable now that her hips had widened dramatically; they were wider than her shoulders, with a gorgeous layer of fat that gave them the smooth hourglass shape that men and women coveted. She was beginning to think of them as ‘baby-making hips’, and every time she made the thought, it gave her a shiver of goosebumps. It scared her how excited the notion that her body could make babies was making her. She could just imagine holding a beautiful little child of her own and letting it suckle at her big, milk-laden breasts.

She shivered at the thought now, before turning red and restraining herself.

“Oh my God, my lips as well,” she said, probing them with a finger.

They had gotten fuller, now appearing perfect and pouty, the kind of lips that were perfect for kissing. In fact, her face and head had changed in other ways; her features softer, her cheekbones higher, and her hair had become longer and thicker, its consistency more soft and luscious. She was now drawing a lot of looks on campus, and many of the men couldn’t help but check her out, especially since it was starting to feel just not quite right to cover herself up. Ever since the lecture theatre incident, she had felt eerily comfortable baring her midriff a little, and wearing yoga pants rather than her professional suit cut. It shamed her, and yet she loved the way it hugged her hips and bottom, and the way it drew men’s eyes.

“Fuck, I just want someone to get me fucking pregnant,” she said, before covering her mouth. “Oh God, why do I want that so badly? I can’t stop thinking about making babies.”

She breathed heavily, and her bosom rose and fell, trembling slightly. Her nipples were hard, and that heat flushed in her again.

“Maybe it will go away if I just have a little sex?” she asked her copy in the mirror. She leaned forward, utterly away at how sexy she appeared, and for once, she felt good about it.

“Yeah. I just need to lose this damn virginity. Then I can get back to studying. That’s it.”

“Oh fuck! Oh God! Oh shit that feels so damn good!”

Rebecca wailed as the man who’d introduced himself as Rob worked his way inside of her. She bucked her hips against his, wrapping her legs around him in desperation as she milked his big cock. She’d never felt like this in her life, but the burning heat to breed was in her mind, and she’d managed to successfully snare a man.

It hadn’t been hard. With her new looks, she’d managed to put on a tight croptop and skirt and made her way into town, her breasts practically straining the fabric of her top even as her ass made a lovely indentation in the back. She’d done up her makeup for the very first time, and while it had taken some effort to get it right, the ruby-red lips look did her massive favours; she looked more desirable and shapely than any woman on the dance floor, and everyone recognised it.

The sight of the gorgeous men around her had caused her to become wet almost immediately, and her nipples hardened against her top, flashing the ‘headlights’ in a way that enticed dance partners. And all the time all she could think about was having each of them inside of her, their hard dicks pushing deep to the entrance of her womb, and ejaculating their seed to plant within her. She had uncharacteristically danced up against several men before Rob approached her; a handsome 6’1 muscle-bound giant of a man, and one that looked to her with a need near as great as her own. She had practically dragged him back to her place, playing with the hardness in his pants on the entire taxi ride home. She ripped off her clothes the second they reached her place, and had licked and caressed and kissed his precious body.

“Don’t stop! Keep going!” she moaned, as Rob thrust faster and faster. His large hands played with her immense tits, and it drove her wild, especially when he leaned forward to kiss her, and her sensitive nipples rubbed against his chest. How could she have avoided this for so long? It was heaven! It was a thought process that dominated her, the sheer pleasure of sex, especially as she drew nearer and nearer to a spectacular climax.

“God, you’re so fucking hot! Your tits are amazing!”

She grunted in satisfaction as he marvelled at her large, rounded booba, which rocked and wobbled with every powerful bucking of their hips.

“Come in me!” she exclaimed. “I want your come inside me!”
“Oh fuck, I’m so close,” Rob groaned, before his eyes shot a little wider open. “Wait, you said you’re on birth control, right?”

“Mmmhhhm,” she moaned, imagining his semen inside her. She couldn’t understand it, she’d never wanted or needed a baby before, but it was as if her instincts had been altered and exaggerated, and now her body needed to make babies. She needed to get pregnant, and it was terrifying to think that she might not. She needed to be round and fat with babies, the more the better.

“Of course I’m on birth control,” she said, purring sensually, and beginning to rock her hips against his hardness, feeling it pulse within her passage, “I’m a good girl, remember?”

Rob smiled, and his thrusting began again, driving her to fits of ecstasy, and only partly from feeling. She was so close, and so was he, so close to becoming parents.

Suddenly her lover tense, and wrapped her legs tightly around his lower back, squeezing hard as he gasped. His large dick throbbed within her, and it gave her shivers of orgasms that coursed through her body, a similar pleasure running through her sensitive tits. And then she felt him come in time to his grunting, a warm stickiness shooting through her vaginal passage and on towards her waiting womb.

“Ah, ah, ah, baby!” she squealed, arching her back and squeezing him even tighter. She needed every last drop of his semen inside her, and she refused to let go until his penis stopped shooting its wonderful issue. She shivered in post-coital pleasure, even as Rob separated from her and collapse at her side, drawing her close. His strong hands wrapped over, clutching her large chest, and she whimpered, submissive to his hold.

“Jesus, that was good. Fuck, you’re an amazing lay, Becca.”

Becca, that was a good name. Much better than Rebecca. Sexier too. It would serve her well, she decided. She traced her fingers idly over her stomach. She couldn’t say how she knew, but it was as if her changed body could somehow feel its ovaries being penetrated by his sperm. A small tensing in her stomach, and she knew for a fact she was pregnant. She was going to be a mother. It scared her, terrified her! She had no idea how to be a mother, or what it entailed. She was meant to be an engineer. Sex and motherhood were never in her plans. And yet, however these changes had come over her, the instinctual drive to reproduce had claimed her, and she was helpless before it. She needed to make babies, babies, and more babies.

“First of many,” she whispered to herself, shaking slightly in anticipation.

She couldn’t wait to grow her pregnant belly. She had a feeling she would be spending a lot of her new life with one.
