Chapter 3: Midnight Rooftop Breeding
The whisper began, not as a cramp, but as a dissonant hum deep in her blood. An awareness that her body was now engaged in clandestine labor, building something with stolen, filthy material. A week passed since the rooftop vow.
Ochaco went about her days as if piloting a familiar machine from a great distance. She ate toast and smiled at Deku over the morning news. She patrolled her designated city sectors, performing the motions of rescue and peace with practiced efficiency. The media praised her for maintaining a “steady, calming presence” amidst her more famously explosive colleagues. If they saw a tightness behind her eyes, they mistook it for focus.
But internally, every sense was tuned to a different frequency. The whisper in her blood was joined by a heightened sensitivity to smell. She noticed the musty odor of an old filing cabinet at the agency with a sudden, nauseating intensity. The smell of greasy takeout containers by a bodega made her stomach flip. She kept mints in her pocket, crunching them constantly, her mouth filling with a thin, saliva more often than not.
And she felt…full. Not from his final, determined effort, but as if her organs had been slightly rearranged. The persistent, pleasant ache she’d grown used to had morphed into a low-level pressure. A lingering heaviness.
She knew it was too soon for definitive signs. Her rational mind shouted this. But her new reality was built on the shattering of rationality. Every queasy wave was a step closer. Every twinge was a potential spasm of implantation. The whisper grew louder, transforming into a daily, murmuring question: Is it there yet?
Her visits to Mineta’s dorm became impatient. Urgent. No longer about sating a frantic lust, but about reinforcement. Augmentation. It felt like tending to a project.
The night she found the first, undeniable change, it was raining.
Not a downpour, but a persistent, cold drizzle that wrapped the city in a slick, grey film. Deku was away for a forty-eight-hour inter-agency summit in Osaka. His video call that evening had been full of bright, tired smiles and updates about revised inter-hero protocols.
After hanging up, the apartment echoed.
She went to the bathroom, took her temperature with a new digital thermometer she’d hidden at the back of the vanity.Elevated. A spike at the expected time, but she hadn’t tracked her cycle in weeks. She just knew the internal hum, the untimed pressure. On a whim, earlier that week, she had bought a box of early detection tests. They sat, unopened, in their CVS bag under the bathroom sink. She told herself she wouldn’t do it. The internet said ten to fourteen days after conception. It had been nine.
She passed the kitchen, poured a glass of water. As she brought the cool glass to her lips, she breathed in the subtle smell of chlorine from the city tap water. A roiling wave of nausea, abrupt and violent, surged up her esophagus. She barely made it to the sink before she vomited. The convulsions were humiliating, animalistic, emptying nothing but acid and a thin string of bile. She rinsed her mouth, shaking.
She knew.
The part of her that was still Ochaco Uraraka recoiled, a stunned animal blinking in the glare of a roadside catastrophe.
The rest of her… moved.
She didn't change. She threw her phone and wallet into the pocket of a long, waterproof trench coat and left the apartment. She walked the ten minutes to the UA Heights Alliance dormitory through the mist, the weather making her invisible.
His door opened after her first knock. The smoke from his usual shitty cigarette was curled around his head like a frayed crown. He seemed to read it on her face before she even stepped inside.
“You’re pale,” he said, stepping aside. He was in gym shorts and nothing else.
“I threw up,” she said, closing the door. Her voice was flat, factual.
His eyes, dark and calculating, scanned her. They dropped to her abdomen, hidden under the belted coat. “Nine days.”
“I know how many days it is.”
He walked back to his bed, where a handheld gaming console glowed on the rumpled sheets. He picked it up, more for something to do with his hands than to play. “Gonna be weeks of that.Maybe months. You thought this was just gonna be some dirty thought to get off on. You gonna get stretch marks. Your nipples’ll turn darker. Real quick, too.”
His words weren't cruel. They were descriptive. An inventory of crimes they were co-committing.
“I can’t do it here,” she said, her gaze sweeping the claustrophobic room. The scene of their initial, reckless deviance suddenly felt insufficient. “Not tonight. It’s not… serious enough.”
He processed that, put the console down. “What do you want? Some fancy hotel? We’re not on a date, Ochaco.”
The sound of her first name on his lips, so rarely used, jolted her. It was jarring.Intimate. She shook her head. “I want somewhere it’s just us.And the city. And no walls to muffle it.”
A slow smirk touched his mouth. He finally stubbed his cigarette out. “You’re getting theatrical. But I know a place.” He grabbed a hoodie and pulled it on over his bare shoulders. “Follow me.”
He led her through the twisting corridors of the dorm, not toward the main entrance, but down a half-lit service stairwell she’d never used. An emergency exit door at the bottom was alarmed, but he produced a keycard from his wallet and swiped it. A light on the panel turned from red to green with a soft beep. “Backup to the backups,” he muttered, shoving the heavy metal door open.
It led to an exterior concrete staircase hugging the side of the dorm building, slick with rain. The cold air hit her, a slap that made her gasp. He didn't hesitate, climbing the steep, wet stairs with a practiced ease. She followed, her shoes skidding once on the worn tread.
The UA campus sprawled below them, a ghostly patchwork of dimmed buildings and shimmering, puddle-strewn lawns. They were on the roof of the main academy building, a vast, flat expanse of asphalt and vents, surrounded by a low, black-painted iron railing. Flickering orange emergency lamps on structural pillars provided scant illumination, creating more shadows than light. The city hum was different up here—drowned, distant, a sound felt more in the chest than the ears. The rain had thinned to a cold, clinging mist.
He walked to a spot near the center, away from the sheer drop of the edges. He turned to face her, pulling the hood from his head. The mist beaded on the strange texture of his hair.
“No one’s come up here to check the HVAC in months. Door auto-locks behind us.” His breath formed a small cloud in the chilly air. “What now, Mama?”
The title she had craved just days earlier now landed like a physical blow, its affectionate diminutive stripped bare into a taunting biological fact.That word. That future. Dangling between them in the cold air.
Instead of answering, she began to move. Her hands went to the belt of her trench coat. She undid it, slowly. Unbuttoned it, starting from the top. She let the damp, heavy fabric slide from her shoulders. It pooled at her feet with a wet slap.
She was naked underneath. She’d come straight from her empty apartment, having undressed for her failed shower after vomiting. Her skin prickled immediately with goosebumps, her nipples hardening into tight, dark peaks against the cold. The rounded swells of her breasts and the heavier curve of her hips seemed magnified in the dim, fractured light. Vulnerable.On display.
He just watched, his expression impossible to read. He wasn’t instantly hard. He looked… clinical. Assessing his handiwork. Or his investment.
“Is that warm enough?” he finally asked, his voice nearly lost in the wind.
“I don’t care,” she said, her teeth beginning to chatter. “This isn’t about being comfortable. It’s about sealing it. Officially.”
“You’re in charge of ceremonies.” He unzipped his hoodie, shrugging it off. His gym shorts were next, pushed down past his hips. The cold didn’t seem to affect him. The thick length of his cock, exposed to the elements, stiffened quickly regardless—a survival mechanism in its own vulgar way. It jutted out, heavy and blatant, between his compact thighs.
“Show me where you want me,” he said.
She walked, her bare feet slapping on the wet, gritty asphalt, to the iron railing that lined the western edge of the roof. Beyond it was a fifteen-story plunge into the UA quad and then the sleeping city beyond. She turned her back to it, to him. The railing’s metal was cold enough to feel like a brand against her fingers. She bent at the waist, placing her palms on the chilled, damp horizontal bar.
The position arched her back and raised her ass, presenting it to the middle of the world, to him, to any stray, improbable satellite that might see. The wind, searching and damp, teased her exposed, vulnerable folds. She’d never felt so openly, terrifyingly lewd. “Here.”
She heard him approach, his bare feet on the wet ground. His hands settled on the flare of her hips, his fingertips shockingly hot against her chilled skin. His thumbs dug into the small of her back, pressing into the muscle there. He squeezed her enormous, cold-numbed cheeks with a grip that was almost possessive.
“Fucking glorious,” he murmured, his breath a warm puff against the back of her thigh. He leaned forward, his chest not touching her back, and she felt the broad, hot crown of his cock push against her. Not probing, just resting there, claiming the space. He was already slick.
The contrast between his searing heat and the cold metal biting into her thighs was nearly unbearable, forcing an intense, visceral awareness of every single part of her body. He spat into his hand again. She heard it. He slicked himself thoroughly, then positioned the blunt head, pushing it through her folds, gathering her own moisture, already beginning despite the chill.
“Still ready for me,” he noted, grinding the head in slow circles. “Getting knocked up just makes you a better cocksleeve, doesn’t it? Warmer. Damn near fucking alive.”
She didn't have words. She just pushed back, a silent, demanding plea.
He entered her.
The sensation was deeper, more profound, than any time before. A stretching pressure that started at her opening and resonated through the entire suspected cavity of her womb. He moved slowly, pressing in until he was sheathed completely inside, a full, anchoring weight.
He paused, buried to the hilt. “Feel that?” he grunted into her ear, having leaned over her. “You feel me sitting right on top of it? Right at the fucking doorstep. Empty this morning, and now I’m home. Hell of a hostess gift.”
Then he began to move, using her with the same measured, efficient motion he’d established on the last, fateful night.This was business. Policy on the monstrous mortgage of their pact. Each pull and thrust was workmanlike, deliberate. The ‘squelch’ was muted by the wind. The rhythmic slaps of his pelvis against her upturned ass echoed faintly. She braced harder against the railing, the cold and pressure blending into a single, dominating sensation.
Her breasts swayed heavily beneath her, a visual metronome to their fucking. Raindrops stung her heated skin. The city was a distant, pulsing grid of light, oblivious.
