A flu virus spreads through the population. After the infection, women are found to grow more muscular, taller (average height 6ft 3 in), aggressive sexually (they are attracted to men primarily), and develop larger penises (average 8 inches, maximum of 12) than men that replace their vaginas. The women grow over a period of months called "the change". Gender roles are upended and people are struggling to cope with the new reality. Some men feel emasculated by the change while others embrace it. Women feel at odds with their upbringing as smaller more demure women with their new powerful bodies primed for sex and action. Some women are embarrassed by their new bodies and don't know how to express their urges or deal with their large penises and muscles and try to hide them--unsuccessfully. These women feel like freaks but still want to give into their huge desire lurking in them. These women struggle with things like random erections, morning wood, peeing standing up, hiding their bulges in their pants. They simultaneously want to be seen as graceful, delicate, beautiful, feminine all the while deeply desire to dominate their boyfriends using their powerful muscles and huge cocks. Meanwhile another group women fully embrace their new bodies and are constantly trying to fuck new men and love their feeling of power and control their new bodies give them. These women wear tight or revealing clothing and make their advances quite obviously. They take pride in seducing men who are hesitant to embrace women's new bodies and pummeling virgins with their thrombin cocks. All characters are 18 years or older. This story takes place in a college coed dorm as the infection first starts to sweep through the school. The women gradually change and both genders have to adapt to the new social and sexual dynamic.

Chapter 2: Tinder and the Terrified Virgin

The metallic scent was still in the air.

It clung to the fibers of her sweatshirt, lingered in the silent dorm room long after Jake had left. Emily lay on her back, staring at the water-stained ceiling, feeling the phantom ache between her legs. It wasn't pleasure. It was the memory of a landslide. Her body felt used, but not by Jake—by itself. It had acted with a mind of its own, a brutal, efficient machine. She touched her lower abdomen, the hard plane of it, and a cold wave of detachment washed over her.

Outside her door, the dormitory hallway was no longer quiet. She could hear everything. The thump of bass from two floors down, the murmur of a TV in the common room, the frantic, whispered conversations passing her door. “…my skin feels like it’s on fire…” “…I grew two inches last night, I swear to God…” The fear was a living thing, seeping under the doors.

She couldn’t stay here. The walls were closing in. The memory of Jake’s face, that mixture of fear and feral hunger, was etched on the backs of her eyelids. She needed air that didn’t smell of sex and panic.

She dressed mechanically: the baggiest jeans she owned, a hoodie twice her size, a beanie pulled low over her hair. In the mirror, she looked like a thug. A fugitive. She shoved her feet into boots and slipped out into the hall.

The atmosphere was electric with suppressed hysteria. A group of girls huddled by the vending machines, one of them crying silently while another gripped her shoulders, her own arms showing new, hard definition under her sweater. They glanced at Emily as she passed, their eyes widening slightly at her height, her broad stride. She looked down, avoiding their gazes, and pushed through the heavy fire door into the stairwell.

Bree’s phone buzzed against her thigh, a persistent, hungry vibration. She smirked, not looking away from the cracked mirror above her desk. She was wearing only a sports bra and briefs, and the reflection was a revelation. Her shoulders were defined deltoids, her biceps curved with new, sleek muscle. Her stomach was flat, ridged. And there, pressing insistently against the tight cotton of her briefs, was the solid, undeniable proof of her change. It was heavier today. More… present.

She picked up the phone. Tinder. A match.

His name was Ethan. The profile picture showed a guy with kind, anxious eyes and a smile that looked like it apologized for existing. His bio read: “Freshman. Likes books, quiet cafes, and genuine conversations. Just looking for something real.”

Bree barked a laugh, short and sharp. “Oh, sweetie,” she muttered to the empty room, her voice a richer alto than it had been last week. “You have no fucking idea what ‘real’ is anymore.”

She swiped right instantly. It was an immediate match.

A message popped up almost comically fast. uhhh hey?

She could picture him, probably sitting on his dorm bed, heart hammering, thumbs sweating. A virgin. She could smell it through the screen. Her own body responded to the thought, a low, throbbing pulse beginning between her legs. It was a new sensation, this blunt, aggressive wanting. It didn’t flutter; it demanded.

Hey Ethan, she typed, her thumbs moving with confident, decisive taps. Something real, huh? You nearby?

The three typing dots appeared, vanished, reappeared. Crosby Hall. You?

Davis. 2nd floor. Room 207. She didn’t ask. She told. Come over. Now.

The dots pulsed. A long minute passed. Is this… are you… changed?

Bree’s grin widened. She lifted her phone, angled the camera down her body, capturing the hard line of her torso, the dramatic swell straining her briefs. She sent the photo. No caption.

The response was immediate. Holy shit.

You coming or not? she wrote. Or are you just “looking for something real” from your mom’s basement?

The challenge hung in the digital space. She watched the dots, her own breath coming a little quicker. The need was a coiling spring in her gut. She wanted to see that fear, that awe, in person. She wanted to use it.

Okay, his final message read. Okay. I’m coming.

The autumn air was brittle cold, but Emily didn’t feel it. She walked across the quad, her hands buried in her hoodie pockets, head down. The campus was a tableau of normalcy punctured by strange, jarring details. A girl with shockingly broad shoulders power-walking while openly sobbing. Two guys standing too close together, one gripping the other’s arm, their faces pale. An alert blared from a dozen phones simultaneously, a harsh, electronic squawk. She glanced at the screen of a passerby: CAMPUS ALERT: SHELTER IN PLACE ADVISORY. AWAIT FURTHER INSTRUCTIONS.

No one was sheltering. Everyone was moving, driven by a restless, fearful energy.

She found herself outside the library, its neo-gothic facade offering a false sense of solidity. She pushed through the heavy doors, seeking the silence of the stacks, a place to disappear.

The silence was gone. The main hall hummed with low, frantic conversation. Students clustered around laptops, watching news feeds. On a large screen, a CDC spokesperson spoke with calibrated calm. “We are urging the public not to panic. The phenomenon, which we are terming Accelerated Physiological Metamorphosis, or APM, appears non-fatal and is currently contained to specific demographic clusters…”

“Bullshit,” someone muttered. “Jenny from Sigma Phi grew three inches and a fucking Adam’s apple overnight. How is that ‘contained’?”

Emily slid past them, deeper into the labyrinth of books. The familiar smell of paper and dust usually soothed her. Now it felt like a tomb. She turned a corner into a secluded aisle on the third floor, dedicated to obscure geography journals.

And she stopped.

A boy was there, sitting on the floor, his back against a shelf of atlases. He had a book open on his knees, but he wasn’t reading. He was staring into the middle distance, his face ghostly in the weak fluorescent light. He was slight, with a mess of brown hair and wire-rimmed glasses. He looked untouched. Normal. The sight was like a punch to her gut.

He sensed her presence and looked up. His eyes, a soft hazel behind the lenses, widened. They traveled up her frame, taking in her heightened stature, the powerful set of her shoulders under the hoodie, the tense line of her jaw. But his gaze held no revulsion, no predatory curiosity. It held a simple, stunned recognition of difference.

“Sorry,” Emily mumbled, her voice rough. She turned to leave.

“Wait.” His voice was quieter than hers, gentle. “You… you don’t have to go. It’s quiet here.”

She paused, her back to him. The offer of simple, undemanding human space was so alien it felt like a trap.

“I’m Ethan,” he said. He didn’t stand up, didn’t approach. He just sat there, a still point in the chaos.

“Emily,” she said, the word torn from her.

“Hi, Emily.” He closed his book. “You look like you’ve seen a ghost.”

She almost laughed. She was the ghost. “Something like that.”

She leaned against the opposite bookshelf, sliding down to sit on the floor, facing him but with the entire aisle between them. The distance felt safe. He studied her, not with Jake’s shocked appraisal, but with a curious, literary attentiveness.

“You’re one of them,” he said finally. It wasn’t an accusation. It was an observation.

She nodded, looking at her hands. They seemed to grow larger as she watched.

“Does it… hurt?” he asked.

The question was so innocent, so devoid of prurient interest, it disarmed her. “Not exactly,” she whispered. “It just… is. And it wants things.”

“What does it want?”

She met his eyes then. “To not be a question anymore.”

He held her gaze for a long moment, then nodded slowly, as if she’d said something profound. He gestured to the book on his lap. “I was trying to read. To escape. But every sentence just seems stupid now.”

“What were you reading?”

“The Metamorphosis,” he said, a faint, ironic smile touching his lips. “Kafka. ‘When Gregor Samsa woke up one morning from unsettling dreams, he found himself changed in his bed into a monstrous vermin.’ Seemed relevant.”

A real, dry laugh escaped her. It felt strange in her throat. “Yeah. A little.”

“He spends the whole story locked in his room,” Ethan said softly, his eyes on the book’s cover. “Terrified of being seen. His family is horrified. They just want him to go away.” He looked up at her. “I’m sorry if people are treating you like that.”

The unexpected kindness was a thorn in her heart. She looked away, her eyes stinging. “My boyfriend fucked me this morning,” she said, the words flat and brutal. “Or I fucked him. I don’t even know. It wasn’t… it wasn’t us.”

Ethan didn’t flinch. He absorbed the statement, his gentle face somber. “That sounds lonely,” he said.

Two words. They undid her. A shudder ran through her frame, a great, seismic release of tension she hadn’t known she was holding. A single hot tear traced a path down her cheek. She wiped it away angrily.

“Why are you being nice?” she asked, her voice thick.

He shrugged, a little helplessly. “Because everyone’s scared. And scared people are either cruel or kind. I’d rather be kind.” He paused. “And because you still look like you. In your eyes. The rest is just… new furniture.”

She stared at him, this strange, quiet boy in the stacks. For the first time since she’d woken up to splintered wood, she felt a thread of connection, fragile but real.

Her phone buzzed in her pocket. A sharp, invasive sound. She pulled it out. A news notification. Then, beneath it, a text from Jake. Her stomach clenched.

We need to talk. Please.

The thread snapped. The real world, with its complications and its horrors, rushed back in. She pushed herself to her feet, her new muscles coiling effortlessly.

“I have to go,” she said.

Ethan looked up at her, his expression unreadable. “Okay.”

“Thank you,” she said, the words inadequate.

He simply nodded, offering her a small, fleeting smile before opening his book again, a retreat into his own world.

She fled the library, the ghost of his kindness a warm, aching spot in her chest. Outside, the sky had darkened prematurely. The shelter-in-place alert buzzed again on her phone. She ignored it. Her path took her past Davis Hall.

On the second floor, a window was open. Room 207. As she passed below, she heard a sound—a sharp, high gasp, followed by a low, commanding murmur. A girl’s voice, rich and full of dark promise. “Just relax, freshman. I’ve got you.”

Emily quickened her pace, a new chill settling in her bones.

The knock on Bree’s door was so soft she almost didn’t hear it. A timid, two-tap sound. She smiled, uncurling herself from her bed. She had changed into loose sweats, the fabric doing little to hide the aggressive outline beneath. She’d left the lights low, a single lamp casting long shadows.

She opened the door.

Ethan stood there, a slight figure swimming in a puffer jacket. His eyes were huge behind his glasses, darting from her face to the powerful lines of her body, then skittering away. He smelled of cold air and nervous sweat.

“You came,” Bree said, leaning against the doorframe, blocking the entrance. She let him look. Let him sweat.

“Yeah,” he breathed. His voice was barely audible.

“Get in here,” she commanded, stepping aside.

He shuffled in, his shoulders hunched. The room was a monument to her new state: a tipped-over bottle of protein powder on the desk, a set of dumbbells in the corner, the air thick with that same metallic, electric scent that hung over everything now.

“Take off your coat,” she said, closing the door with a definitive click. The lock engaged.

He fumbled with the zipper, his fingers clumsy. She watched, her arms crossed, the muscle in her biceps flexing unconsciously. He finally got it off, letting the jacket fall to the floor. He was thin underneath, a boyish frame.

“So,” Bree said, stepping into his space. He had to tilt his head back to look at her. She was at least three inches taller. “You wanted something real.”

“I… I guess,” he stammered.

“This is real,” she said, taking his hand. His skin was cold. She placed his palm flat against the hard plane of her lower stomach, over the sweats. She pressed down, forcing him to feel the solid, unyielding presence beneath the fabric. He jerked, but didn’t pull away. His breath hitched.

“Do you feel that?” she murmured, her face close to his. He nodded, mutely. “That’s the new reality, Ethan. No more bullshit. No more ‘genuine conversations.’ Just this.” She moved his hand down, over the thick, prominent bulge. He made a small, choked sound.

She kissed him then. It wasn’t a kiss of affection. It was a claim. Her mouth was hungry, dominating, her tongue forcing its way past his lips. He tasted of spearmint gum and fear. His hands came up, fluttering at his sides before finally settling, trembling, on her waist. She could break him so easily.

She broke the kiss, breathing heavily. His glasses were fogged. “Have you ever been with a girl?” she asked, already knowing the answer.

He shook his head.

“You’re not with a girl now,” she said, her voice a dark caress. “Not anymore.”

She backed him toward the bed, a single, slow step at a time until his knees hit the mattress and he sank down. She stood over him, looking down at his prone form. The power was intoxicating, a headier drug than any whiskey. She peeled off her sweatshirt, then the tank top underneath. Her torso was a landscape of new muscle, her breasts smaller, firmer. She saw his eyes devour the sight, a mixture of terror and fascination.

“Take off your clothes,” she ordered.

He did, his movements slow and shaky. He was pale, slender, almost hairless. Completely exposed. He made no move to cover himself. He just stared up at her, utterly captive.

Bree hooked her thumbs into the waistband of her sweats and pushed them down, along with her briefs. She let them pool at her feet. She watched his eyes widen, his mouth fall open as he saw her, fully revealed. The thick, heavy cock that rose from its thatch of dark hair was fully erect now, a stark, brutal statement against the soft light.

“Holy fuck,” he whispered, the curse sounding pious in his trembling voice.

“Yeah,” she said, her voice thick with pride and need. “That’s what I’ve got now.”

She flexed her biceps menacingly.

She climbed onto the bed, kneeling over him, her knees pinning his thighs. She took herself in hand, giving her length a few slow, sure strokes. Precum beaded at the tip. He watched, hypnotized.

“Have you ever done this?” she asked, though she knew. “Taken a cock?”

He shook his head again, his Adam’s apple bobbing.

“It’s gonna hurt,” she said, not unkindly, but with absolute certainty. “But you’ll take it. Because you came here. You wanted to see.”

She spat into her palm, a crude lubricant, and slicked herself. Then she positioned the broad, flushed head against his tight, untouched entrance. He tensed, a whole-body flinch.

“Relax,” she commanded, applying pressure.

He cried out—a sharp, pained gasp—as she pushed forward, the thick crown stretching him impossibly wide. She felt the fierce, hot resistance of his body, the clenching panic. She paused, letting him pant beneath her.

“Breathe,” she growled.

He sobbed, a wet, broken sound, but he nodded, his hands gripping the sheets beside his head. She pushed again, sinking another unforgiving inch into his clutching heat. The sensation was unbelievable—a tight, velvet vise, a conquest. She threw her head back, a groan rumbling from her chest.

She began to move, establishing a ruthless, piston-like rhythm. The bed frame slammed against the wall. Each thrust punched a muffled sound from Ethan’s throat—pain, shock, and beneath it, a thread of ragged, bewildered arousal.

Each thrust punched a muffled sound from Ethan’s throat—pain, shock, and beneath it, a thread of ragged, bewildered arousal. Bree watched his face contort, his glasses askew, his mouth a soft ‘o’ of overwhelmed sensation. Her own pleasure was a blunt, building force, a deep animal gratification that had nothing to do with tenderness. “You like that, virgin?” she grunted, her voice rough. “You like getting split open by a real cock?”

She leaned down, bracing her hands on either side of his head, her biceps flexing into hard, defined mounds of muscle. The show of strength was deliberate, a display of her new power over his pliant, trembling body. “Look at you,” she hissed, her breath hot against his ear. “Taking it like a good little bitch. Your tight little ass is fucking mine now.”

Ethan whimpered, a sound lost in the slam of the bed against the wall. His own untouched erection lay against his stomach, leaking. She saw his confusion, the war between shame and a brutal, unprecedented need. She pistoned into him faster, the wet, slapping sounds of their joining filling the stale room. “Gonna come inside you,” she promised, the words filthy and low. “Gonna fill you up. Make you remember what you are.”

His legs shook, his heels digging into the mattress. A tear escaped from under his fogged lens. Bree reveled in it. This was control, absolute and visceral. She fucked him with a relentless, driving rhythm, chasing her own peak, using his body as a vessel for her strange, new hunger. The climax tore through her with a guttural roar, a release that felt like dominance made physical. She collapsed onto him, the weight of her transformed body pinning his slight frame completely.

She rolled off after a moment, leaving him gasping on the damp sheets. The room stank of sex and sweat. She stood, stretching, the muscles in her back and arms rippling. She looked down at him, a broken, beautiful mess. “Bathroom’s down the hall,” she said, her tone dismissive now, the hunger sated. “Clean yourself up.”

Ethan moved slowly, as if every part of him ached. He gathered his clothes with unsteady hands, not meeting her eyes. He shuffled out without a word, the door clicking shut softly behind him.

Out in the cold hallway, the reality of what he’d done crashed into him. His body felt used, scraped raw. A sore, deep ache pulsed inside him. He leaned against the cinderblock wall, breathing in the smell of industrial cleaner, trying to erase the scent of her from his skin. His mind replayed the feel of her hands, the look on her face, the things she’d said. Shame burned his cheeks, but a traitorous, hot thread of memory coiled in his gut.

He thought of Emily, then. The raw pain in her eyes in the library. The way she’d said, “It wants things.” He understood now. He’d been a thing that was wanted. Used. A part of him was horrified. Another part, a deeper, darker part, felt cracked open, exposed to a new and terrifying world.

Back in her room, Bree stared at the closed door. The high of power was fading, leaving a familiar hollow in its wake. She looked at her reflection in the cracked mirror—the powerful body, the satisfied smirk already slipping from her face. It wasn’t enough. The hunger would be back. It was always back.

She picked up her phone. Scrolling through her matches, she stopped on a new one. A linebacker from the football team, his profile a smirk and a flexed bicep. His first message was already there: Heard you’re packing now. Wanna compare?

A slow smile spread across her face. The hollow inside her yawned, eager to be filled again.
