Chubby Cheating Dorm Room Creampies

*This story features chubby women, reluctantly giving in to cheating, and a breeding kink. If these aren't your thing, don't say I didn't warn you.*

*****

Piper's cunt was a creamy, gooey mess. She'd been fingering it all morning when she should have been studying, trying to stave off the horniness, but the heat just wouldn't let up. It had been day and days now where she'd been unable to think about anything except a man holding her down, fucking her mercilessly, and then pumping a healthy, fat load of warm cream into her fertile little belly.

Her boyfriend Noah was away for the whole week on a boys' trip at the worst time. She had just started ovulating, and the mating urge was hitting Piper hard, like it always did.

A moan escaped the college sophomore's lips as her finger worked into a frenzied pace. Her wide hips lifted off the bed and her whole body began to tremble.

Her thoughts were drifting to a bad place... again. As she rubbed her clit furiously, she couldn't help but fantasize about Bret.

Bret, the hot, blonde, muscular lacrosse player.

Bret, her roommate.

Like her whole family, Piper was exceptionally fertile, and her body showed it off. Her long, fiery red hair drew men like moths to a flame. Her G-cup breasts, always a handful, were more pronounced this time of the month, swelling slightly and perking up with little pink nipples under her white lace bra. Her pale skin, just barely sun-kissed, took on a radiant glow. Even the air around her seemed to thicken with an almost palpable haze of breeding pheromones.

Last week, she'd happened to walk in on Bret in the bathroom, and for a split second, before screaming and slamming the door, she'd glimpsed him fully naked. That moment was seared into her memory.

His rock-hard abs curving down into a pronounced adonis belt.

His muscular thighs.

And his penis.

Fuck... that big penis.

Piper drooled every time she thought about it. It must have been seven, eight inches long at least, and that was just flaccid. She burned to know what it looked like hard.

As her fingers moved madly over her clit and she thought about taking her roommate Bret's big cock between her thick thighs, that flaccid fuck-sausage slowly hardening into a fat, curved rod and thrusting inside her, she felt a surge of excitement mixed with a hint of guilt. And fear.

Noah's dick was... three? Maybe four inches hard. Maybe. He got embarrassed every time he talked about it.

*It's okay*, Piper would tell him. *I love your penis. It's perfect. The big ones scare me.*

*I guess that's true*, Piper thought to herself, her back against the mattress, working her sopping wet crotch with frenzied hand motions, hips high in the air. Bret's penis did scare her. A hot fear that manifested as burning desire.

Deep down, she knew, a big cock attached to a perfect specimen of man like Bret was so much more likely to plunge itself deep into her mating-wet cunt, kiss her trembling cervix, and spurt a steaming, churning load of dangerously potent genetic material directly into her vulnerable womb, where it would surely take, ballooning her chubby little belly with a healthy baby.

Both of Piper's sisters, also cute chubby redheads, had been knocked up at 19 years old. They'd been unable to stop themselves from letting their virile boyfriends press them into mattresses, slide thick cocks inside their needy, wet pussies, and disgorge load after baby-making load of wriggling sperm deep inside. Now they both lived as naked and perpetually pregnant housewives, too breeding-crazed to stop letting their now-husbands bend them over and squirt babies into their bellies again and again and again.

Piper imagined Bret's strong hands gripping her breeding hips and his deep voice whispering dirty promises in her ear. Eyes closed, her breathing quickened as she pictured his chiseled jawline and piercing blue eyes. She imagined the way he would kiss her, hard and demanding, as his cock plunged through her engorged labia to thrust satisfyingly home.

Piper's ovulation days seemed to pass in a haze of hot need. She would wake up sopping wet, clenching her thighs together, from a dream about hard cock penetrating her. Then she'd float through her day in a state of nonstop arousal, the heat between her drooling thighs continuous, finding herself rubbing them together subconsciously. She was more animal in heat than human, plunging her fingers into her juice-soaked panties to pummel her puffy little clit at every opportunity.

In her instinctive desperation to be fucked pregnant, she'd be all over Noah, and would always end up disappointed. His sex drive was so low that he turned her away most times, and when he did capitulate, it was to spend 30 or 40 seconds thrusting with that little penis, locked away behind a condom slathered with spermicidal lube. She never came on his cock. She simply couldn't. He simply couldn't satisfy her deepest and most animalistic urges.

Every month during her ovulation window, Noah's pathetic performance left Piper as a mess of horny need. Her rational mind got muscled to the side by the animal desperation to be held down, cummed in, and violently bred. By her evolutionary purpose, to spread her thick thighs and take a hot man's cock inside her and let it knock her up. So she'd resort to constant masturbation just to keep it at bay.

But last week something had changed. It was September, and a new semester was about to start. She'd moved in with Bret, this hot senior, this six foot five Greek god of a man.

She knew deep down it was a bad idea to apply for the coed dorms. Another dumb decision made in a previous ovulation window. Outwardly, she'd told people it was about social justice, gender equality, things like that, of course girls and boys could live together.

But deep down, she knew that it was a decision steered by her lizard brain's instinctive desperation. By that little egg in her womb radiating wave after wave of hot need and taking control of her mind. Forcing her to think about men. Their muscles, their cocks, their smiles, their stubble, their tousled hair. Becoming their perfect hyper-feminized bimbo, their chubby wide-hipped fertility goddess, at the mercy of them, holding her down, thrusting thick penises inside her ripe, wet cunt...

Piper was getting closer and closer. She could feel the orgasm rising up her spine. Her mouth opened and her eyes began to roll back involuntarily.

"Bret..."

Imagining Bret's body, glistening with sweat as he jogged across the field at lacrosse practice, Piper let a moan escape her lips.

"B-Bret-t-ttt..."

"Yeah?" Bret said.

Piper's eyes shot open and her hips dropped, causing her thick butt to bounce off the mattress, making a squelching sound as her butt cheeks squished against the soaking puddle of pussy juice.

"OH MY GOD, WHAT THE FUCK BRET?" she screamed, grabbing the crumpled topsheet to partially cover herself.

Bret was grinning, leaning one arm against the door, shirtless. His broad shoulders and chiseled chest had a warm glow from lacrosse practice earlier that day. Piper's pussy clenched at the heavenly sight and another wave of warm fuck juice gushed into the mattress.

"You left the door open, Piper. We were supposed to meet now to grab dinner, remember? It's 5 o'clock".

A surge of realization shot through Piper. She'd been so obsessed with getting off that she'd completely lost track of time.

Bret cocked his head, his grin widening. "But it looks like you've been having a real feast in here."

Piper's cheeks flushed red. Ugh, he was just so fucking hot, this tall, masculine hunk in her doorway. Staring at him, her hips started to ache with unfulfilled desire. His muscular body absolutely oozed testosterone. Her body was trying hard to betray her beleaguered morals, vibrating with the need to mate with this gorgeous man, the kind of man whose genes her animal reproductive instincts desperately wanted to take in, mix with, and pass on, whether her conscious mind liked it or not.

She ached to bear his children. But she couldn't. She was a college student, with a boyfriend! She knew that cock would fuck its way into her dropping out to become a mating vessel for his beautiful seed, a full-time momma for his many, many babies. She just couldn't let that happen. She had to snap out of it.

"I-" Piper stammered, blushing fiercely, "I just, um, I forgot, is all..."

Standing firm was tough. She was so wildly attracted to him it was driving her insane.

Bret chuckled, a gleam in his eye. "It's okay, I get it. Noah's in Aspen, how else are you gonna get off?"

He bit his lip as his eyes ran up and down her sweaty curves. "Shame, though, because you look extra breedable today."

Piper's breath caught in her throat and a shiver ran through her thick thighs.

Bret's voice got low and he smirked. "Do you... need some help?"

Piper's eyes lost focus and her brain started to melt with a burning heat. She stuttered, barely able to form coherent words.

"Um... well... I don't know if..."

"What's the matter?" Bret said, sauntering over. "Thinking about Stacey and Melanie?"

Piper's cunt muscles spasmed.

There were rumors about Bret. Rumors that he'd gotten a bunch of other girls pregnant. That younger college girls threw themselves at him and he always refused birth control. Rumors that, delirious with desire, they'd throw caution to the wind, wrap their legs around him, and let him cum deep inside, unprotected.

Stacey and Melanie were two thick girls in another dorm who both dropped out during the spring semester to have babies, and the rumor was that Bret was the breeding stud who'd pumped them into the girls' bellies.

And those were just the two she'd heard about. There were whispers that in years past, he'd fathered even more. A lot more. With a lot of different women, most of them with big tits, thick thighs, and wide hips.

Bret had a type. Fertility-goddess bodies. Just like Piper.

Piper imagined Stacey's big belly. She'd seen it on Insta the day before, bulging, heavy with twins. She imagined the pictures from the hospital delivery room Melanie posted a few weeks ago, cradling a healthy set of triplets, each with blonde hair, just like Bret.

"Is-is it... true?" Piper whispered, agog at the sheer stack of rippling muscle towering before her.

"That I'm good at convincing girls to let me fuck them?" Bret said, smiling, his hand sliding up to take hold of the topsheet.

"That I cum in them and knock them up?" He pulled gently, and topsheet began to slide off Piper's chubby, naked body.

"...Maybe."

Piper was trembling. She let her thick, sumptuous curves be gradually exposed by this hot hunk standing before her, this breeding stud who'd thrust his big cock into pussy after warm, willing pussy and sowed his potent seed all over campus, filling tummies fat with healthy babies left and right. She burned with the irresistible desire to let him fuck her pregnant. But she had to resist his undeniable charm. For Noah's sake, for her own, she just had to.

As the topsheet moved over them, Piper's thick thighs had been spreading on their own, subconsciously widening at the approach of the muscular approaching male. A pool of pussy juice revealed itself beneath them, diffusing the unmistakable aroma of pungent female desire.

Bret was nearly right up against her now, sweat dripping down his hot abs, his cock hardening in his gym shorts. Inches from the mattress, so near her wet pussy she could practically feel the heat radiating off it.

"You'd look so cute pregnant with my baby," he whispered.

"We- we ca..."

Piper struggled to find the right words. She didn't want to give in. But it was so hard to resist this gorgeous man in her frenzied urge to take raw cock and make babies.

"I don't know if..."

Bret grinned as he moved a muscular arm up to cradle Piper's round face in his big hand, brushing her red hair behind her ear as he did. She gasped, eyes dilating with urgent need.

"Let's see how things go, baby."

Her cunt spasmed and another drool of pussy juice dribbled out. Her resolve was weakening with each passing moment. Her cunt was built to draw his cum deep into her ready, fertile womb. She was feeling increasingly helpless against her all-consuming urge to mate with this stud.

His other hand pulled his now rock-hard penis out of his gym shorts. With a flinging motion it sprang out and thwacked against Piper's thick, creamy-white inner thigh. It was eight inches long and cradled with thick veins. Two heavy avocado-sized testicles hung low underneath, all smoothly shaved to show off his gorgeous reproductive organs in all their glory. This was truly the equipment of a world-class male, built to penetrate deep into pussies and pump babies into them as they orgasmed.

"Bret... mmmmnf..."

The tip of his perfect penis pressed against her labia, brushing the engorged clit she'd just been rubbing while screaming his name.

"Maybe just the tip," he whispered.

As he spoke, he dragged the cock head up and down her juicy slit, sliding it against her thick, flared-out labia.

Jolts of pleasure ran up her spine. Piper could only moan at the exquisite sensation of him teasing her throbbing wet cunt. As he rubbed it against her warm folds, it slowly slipped deeper into them, until it was making closer and closer circles around her tight hole.

"Bret..." Piper whined, "we shouldn't..."

"Just for a second." Bret whispered in Piper's ear.

"Ummm... mmmnf..."

"Just to see how it feels."

Piper whimpered and bit her lip. "Well... mmmnnnnffff... okay... j-just the tip..."

"Good girl," Bret said, his voice low and hoarse with understated triumph, and the enormous head of his penis began to press its way inside her. Her pussy was so dripping wet with urgent need that the well-lubricated cock slid in easily, gliding smoothly past engorged labia lips and clenching cunt muscles. She gasped with utter delight as the thick cock filled her, reaching further than she'd even known it was possible for a man to penetrate. Gently, lovingly, the tip of the engorged cock head kissed her puffy, throbbing cervix.

"Oops," Bret said, smirking. Piper could only whimper with pleasure.

She urged her big hips forward to press against Bret's torso, drawing the immense fuck tool in to the hilt, until her pale, trembling thighs were squished against his tanned hips.

Something about his callousness, the way he cut through her inhibitions to give her exactly what she needed, was so satisfying and refreshing. Fuck, she loved being treated like his slut. She delighted in the way he took what he wanted. She felt so needed and so satisfyingly full of the most delicious penis she'd ever seen.

Pressing her lace-covered breasts into his abs and her cheek to his chest, Piper could only let out a feminine whimper of desire.

As he settled into a slow, deliberate pace of thrusting, his other hand reached around and with one hand motion unhooked her white lace bra. Piper's big breasts began to bounce with the force of his thrusting hips against her soft thighs, causing the bra to fall to the floor of the dorm room.

Bret began lovingly groping her ample chest, squeezing her ovulation-puffy boobs and idly playing with the hardening pink nipples.

Piper's tight cunt squeezed the girthy penis as it reached depths never before stretched with a thwap-thwap-thwap of muscled legs against chubby thighs. Bret's torso slapped again and again against her chubby little pubic mound, spreading her squelching wet labia lips with each meaty slap to gently tap against her clit again and again.

Breathing heavily, Bret groaned, "I knew from the moment... I moved in last week... that it'd be easy to take you... from that weak bitch of a boyfriend."

"D-Don't... don't tell Noah... p-please..." she mewled weakly, thick legs spreading into the air, panting as her boobs and belly bounced with each percussive slap of his toned body.

"Why?" Bret asked, grinning, "Isn't he going to realize when your belly starts to swell with my baby?"

Piper whined and wrapped her thick legs around him, locking them around his waist as he thrusted to keep him in deep.

"We-We shouldn't... you should probably p-pull out..."

At the sound of that idea Bret started thrusting harder. Bret's heavy full balls slapped against Piper's squirming round ass while he pounded against her wide hips and meaty thighs.

Plap. Plap. Plop. Plap.

"Fuck, Piper," Bret groaned, increasing the pace of his thrusts, grabbing and squeezing her chubby little soft belly as withdrew and thrusted deep again and again, "how am I supposed to pull out... when you feel this good?"

Piper moaned at the increased pace and squeezed him with her thighs. The wet, meaty slaps of their bodies slamming together made increasingly loud, rhythmic squelching sounds.

"You were made to take my cock... and have my babies," he groaned, wrapping a hand around her throat. "Deep down... you crave my seed inside you."

*Ugh, fuck, it's so true*, she thought. She just crumpled so easily when a hot man flexed control over her. It made her cunt dripping wet. Whether she liked it or not, her body was made to be grabbed, held down, and bred by a strong, virile man like Bret. It made her pussy gush every time he was forceful, patriarchal, powerful, intent on taking what was his, driven by the alpha male desire to pump his babies into every female in heat he could pin down. A man like him deserved to breed.

"And that's why..." he breathed, "you're going to beg me to knock you up."

"Mmmmmnn..." she whimpered.

Gripping his strong arms as he leaned into her with relentless thrusts, she shivered with satisfaction. She loved his masculine smell, the way he grabbed her and took what he wanted, his obsession with her belly and her womb, his clear desire to pump her full of cum and make her his breeding cow.

"Admit it," Bret grunted, "We'd make such strong, healthy babies."

"Mmm-hmmmm... ungh!" she moaned and squealed underneath him.

Her cunt muscles were clenching rhythmically now, sensing instinctively that his cum was close, working the big pistoning cock to try and coax his warm, delicious baby batter up and into her fertile little belly.

"I just... need to be inside you raw..." Bret snorted, his thrusts moving faster and faster. "It's not enough to just... fuck you... to take your body from your cuck boyfriend..."

Piper bit her lip as her moans intensified. It was so bad, but so fucking hot, the way Bret was stealing her from her boyfriend. Claiming her as his. Exerting the will to breed, as the stronger male with healthier genes. The ache of raw desire to have his beautiful babies utterly consumed her.

Drawing his face close to hers, he groaned, "You're a fertility goddess, Piper... a baby-making machine... built to be fucked... and bred."

A billion years of evolution had honed her thick body into a receptive vessel for the absolute strongest, most masculine stud she could find, and that was undeniably Bret. It felt so deliciously good to discard a weaker male and just give into those instincts fully, to open her legs for him and let him pound that rock-hard penis into her thick hips.

He was fucking her with a desperate rhythm now, hunky chest pinning her down against the mattress, her big breasts pressed up hard against his smooth pecs. His heavy balls were starting to draw up close, ready to disgorge the hot breeding cream within.

"I'm going to cum inside your tight cunt... and get you pregnant," Bret grunted.

A wave of hot desire pulsed through her, and her resolve shattered.

"Y-yes, please," she whispered.

She wrapped her arms around him as she desperately kissed him for the first time, her thick lips meeting his, licking his tongue and sucking his lips urgently. As their faces parted, a thin trail of drool suspended between them, she spoke softly, looking up into his eyes lovingly.
