Chapter 23: Dual-Sex Desperation
The silence after the pod swallowed Heechul was deafening. It was a physical weight, pressing in on Donghae’s eardrums after the assault of the alarms. He and Hyukjae stood locked together, their harsh breaths the only sound in the bright, sterile room. The fluorescents hummed a bland, ordinary tune.
Hyukjae’s body tensed first. It wasn’t a shiver. It was a deep, internal convulsion that ran through her spine.
“Oh,” she said, a small, punched-out sound.
Her hands flew to her swollen stomach. Under the worn cotton of her sweater, her belly rippled. Not a kick. Something else, a wave of motion that was too fast, too surface-level. The skin tightened, distorting.
“Donghae.”
He held her tighter. “It’s the shock. It’s just–”
“No.”
Another ripple, more violent. A visible tremor under her skin. Her face, pale and slick with sweat, contorted. She gasped, bending forward, her full weight suddenly sagging against him. He stumbled, lowering them both to their knees on the cold floor, careful of her belly.
“Something’s wrong,” she panted, her voice thick with pain. “It’s… it’s moving. Not the baby. Something else.”
She groaned, a low, tearing sound, and clawed at the waistband of her torn jeans. “Get these off. Get them off me!”
He fumbled with the denim, yanking the ripped fabric down her thighs. She kicked them away, kneeling naked from the waist down on the linoleum, her heavy stomach pressed against her thighs. She was staring down at herself, at the patch of dark curls between her legs, her eyes wide with dawning horror.
“It feels… like before,” she whispered. “When it started. In the pod. That… humming.”
Donghae followed her gaze. A faint, shimmering heat-haze seemed to emanate from her skin. It was the same pinkish-silver energy that had pulsed within the containment pod.
“The field,” he said, his blood turning to ice. “It’s not off. It’s… resonant. You were the template. Heechul’s in there now. It’s reactivating you.”
Before he could finish the thought, Hyukjae screamed.
It wasn’t a scream of pain, though pain was there. It was a scream of violent, shocking transformation. Her body arched backwards, back bowed like a drawn bow. Between her legs, her vulva, already slick from their frantic fucking minutes before, flushed a deep, angry red and seemed to swell. The lips parted, glistening, and then began to distend.
Something was pushing its way out.
“What the fuck,” Donghae breathed, paralyzed.
It emerged, wet and impossibly, horrifyingly erect: the head of a cock. It was her cock. Hyukjae’s cock. The flesh was a flushed pink, the same shade as her nipples, the veins standing out in stark relief as it slid out of her, impossibly, from inside her. It wasn’t replacing her female sex; it was erupting from it, a brutal addition. She now had both, a vulva stretched obscenely around the base of the new shaft, her clit swelling into the glans.
“Ah—ah, fuck—fuck—!” she sobbed, her hands gripping her own thighs, knuckles white. Her newly-formed erection stood proudly, weeping a clear bead of precum at the tip.
The transformation wasn’t gentle. Muscles in her abdomen writhed under the skin, re-knitting. Her hips seemed to broaden slightly, her chest swelling further until the buttons on her sweater strained. She was hyper-female and newly, violently male, all at once. A twisted masterpiece of Heechul’s unstable science.
Panting, she looked up at Donghae. Her eyes were wild, but a grim, desperate lucidity was in them. Her old self, the one who faced challenges head-on, surged to the surface through the agony.
“It’s trying to finish what it started,” she rasped. “Or start something new. Overloading. Don’t let it think. Don’t let it settle.”
She reached for him, one hand wrapping around her own new, strange erection, stroking it roughly. A moan, part anguish, part perverse pleasure, tore from her throat. “Fuck me. Right now. In both holes. Fill me so deep, so completely, it… it overloads the circuit. Give it too much data. Confuse the fuck out of it.”
Donghae’s mind shut down. Rational thought—fear, disgust, awe—dissolved. There was only her command, and the raw, urgent need to obey. To fight the experiment with the only weapon they had left: their own chaotic, desperate biology.
He shoved his jeans and boxers down his legs, his cock springing back to full, hard readiness. The sight of her—kneeling, belly heavy, her pussy dripping and her own cock jutting out—was the most obscene, terrifying, and electrifying thing he had ever seen.
He moved behind her. “Lean forward,” he growled, his voice unrecognizable.
She braced her hands on the cold floor, presenting herself. Her new cock hung beneath her, stiff. Behind it, her cunt glistened, swollen and open.
Donghae spat into his palm, slicked himself, and positioned the head of his cock at her entrance. He didn’t enter slowly. He drove into her pussy in one relentless thrust, burying himself to the hilt in her tight, searing heat.
Hyukjae cried out, a ragged scream that echoed off the lab walls. Her internal muscles fluttered wildly around him, a chaotic, gripping rhythm.
“Now the other,” she gasped, reaching back between her own legs. Her fingers wrapped around her new cock, pointing it backwards toward him, an offering. “Fuck my dick. Use your hand. Do it. Milk it while you fuck my cunt.”
The filth of the command, the sheer impossibility of it, sent a jolt of raw lust straight to his core. He wrapped his right hand around her erection. It was hot and solid in his grip, a foreign, living part of her. He began to stroke her in time with his thrusts, a rough, twisting motion.
The rhythm was insane. He was pistoning into her soaked pussy, each slam jostling her body, making her tits sway in her sweater, while his fist pumped her cock with savage efficiency. The lewd, wet symphony of it filled the silent lab—the slap of his hips against her ass, the slick sound of her cunt taking him, the soft friction of his hand on her shaft.
“Fuck! Yes! Just like that!” Hyukjae shouted, her voice breaking. She was pushing back against him, meeting every thrust, her own hand joining his on her cock for a few strokes before digging her nails into the linoleum. “Confuse it! Give it too much! Fucking… contradictory signals!”
Donghae felt her pussy begin to contract in a different pattern, not the rhythmic pulses of orgasm, but a frantic, stuttering series of clenches. Her cock in his hand twitched violently, and a thick stream of clear precum, not yet semen, spurted onto the floor beneath her. It was a dry-run, her body misfiring.
“More!” she screamed, her body trembling violently. “I can feel it… the hum… it’s buzzing inside me! Harder, Donghae! Break the fucking connection!”
He obeyed, slamming into her with abandon, his balls slapping against her, his hand a blur on her cock. He leaned over her, biting at the sweater-covered nape of her neck. He was claiming every part of her, male and female, a frantic bid for dominance over the phantom science in her veins.
Her pussy suddenly gushed, a flood of her own fluids mixing with his spit and sweat. Her cock erupted in his hand, not with semen, but with another, thicker gout of that same clear, slick liquid. It was as if her entire reproductive system was short-circuiting.
The shimmering heat-haze around her skin flared bright pink, then silver, then sputtered erratically.
“Now!” she shrieked. “Come inside me! Flood it! Do it!”
The command tipped him over the edge. With a roar that tore from the depths of his chest, Donghae thrust once, twice, three more times, impossibly deep, and came. His orgasm was a torrent, a violent expulsion, pumping his release into her clutching, chaotic channel.
At the exact same moment, Hyukjae’s body convulsed in a seizure that looked nothing like pleasure. Her back arched, her mouth open in a silent scream. Her cock in his hand gave one final, violent jerk, and a thin, milky-white substance—actual semen, but in a small, pathetic spur—joined the mess on the floor.
The pinkish-silver haze around her skin flickered like a dying bulb, flashed once with a blinding intensity, and vanished.
The humming stopped. Not just from her. The pod behind them, dark and silent, emitted a final, deep click.
Hyukjae collapsed forward onto the floor, utterly spent. Donghae fell beside her, pulling out of her with a soft, wet sound. They lay there on the cold linoleum, panting, surrounded by the mixed evidence of their violent attempt at a cure. The air smelled of sex, sweat, and the sharp, ozone-like scent of discharged energy.
Slowly, trembling, Hyukjae pushed herself up onto her elbows. She looked down between her legs.
Her new cock was gone. Vanished. Only her swollen vulva remained, red and used, with his semen leaking from it. She touched herself, a tentative probe, as if confirming reality.
“It’s… receded,” she whispered, her voice hoarse.
She rolled onto her side, facing him, her pregnant belly a firm curve between them. The violent rippling under her skin had ceased. Only the normal, gentle movements of the baby remained.
Donghae reached out, his hand shaking, and cupped her cheek. She leaned into it, her eyes closing.
The main laboratory door hissed, the pneumatic lock disengaging with a mundane sigh. The lockdown was over.
From the dark, silent pod, a single, hairline crack appeared on its previously flawless surface. It spread with a quiet, brittle sound, then stopped.
They were no longer trapped. But as Donghae stared at that crack, a new kind of cold settled in his stomach. Whatever they had done, whatever they had triggered by putting Heechul inside his own machine, it was not over. It was just contained. And it was cracked.
