Chapter 40: Scientific Method
The lab was a tomb of forgotten science. Flickering light from an overhead sodium lamp buzzed incessantly, painting everything in a sickly yellow. The air was cold, carrying the sharp tang of antiseptic and the deeper, more unsettling scent of ozone and organic decay. Evie shivered, clutching Clare’s hand. Clare’s grip was vice-tight, her knuckles white.
Dr. Anya Sharma moved around them with the quiet efficiency of a spider. Her lab coat was pristine, a stark white flag in the grimy room. Her green eyes, behind thin wire-framed glasses, held no warmth, only a voracious curiosity. She observed them the way one might observe a particularly fascinating stain under a microscope.
“The voluntary recall of the serum was, of course, a bureaucratic formality,” Dr. Sharma said, her voice clipped and precise. She tapped a tablet, scrolling through lines of cascading data. “The genie, as they say, does not go back into the bottle. Not for those who have already… expressed its potential.”
Clare stood rigidly, naked beneath a thin paper gown that did nothing to hide the imposing outline of her new cock. It hung heavy between her thighs, a blunt fact of flesh. “You told us the effects would be temporary. A fluctuation.”
“I said the initial presentation might be variable,” Sharma corrected, not looking up. “The body seeks a new homeostasis. Yours has clearly found one.” Her gaze lifted, sweeping over Clare’s form with appraising coldness. “A remarkable one. The symmetry is… unexpected.” Her eyes flicked to Evie. “In your case, the expression is less dramatic but no less integrated. The serum reads underlying genetic potentials, amplifies them based on psychic and physiological feedback loops. Your insecurities, Miss Reed, and your desires, Miss Bellweather… they are not just drivers. They are the blueprint.”
Evie flushed. The room felt airless. “We didn’t ask for this.”
“You did,” Sharma said simply. “Not in words, perhaps. But in every synaptic pulse of longing. The serum is a mirror. A very literal one.” She set the tablet down and pulled on a pair of latex gloves. The snap was obscenely loud. “Now. I need to assess structural integrity. Metabolic load. Miss Bellweather, on the table, please. Lithotomy position.”
Clare didn’t move. Her jaw was clenched, a muscle ticking in her temple. Evie squeezed her hand. “Clare,” she whispered.
Slowly, with a dignity that made Evie’s heart ache, Clare released her hand and walked to the rusted surgical table in the center of the room. The paper gown rustled as she lay back, placed her feet in the cold steel stirrups, and slid forward until her ass was at the table’s edge. She stared at the cracked ceiling tiles, her face a mask of stoic humiliation.
Dr. Sharma approached, a tray of instruments clattering beside her. She didn’t speak. She merely pushed the paper gown up to Clare’s waist, exposing her fully. The damp, musky scent of their earlier sex still clung to Clare’s skin, a shocking perfume in the sterile air.
Sharma’s gloved fingers, cool and impersonal, parted Clare’s folds. Clare flinched but remained silent. Evie watched, her own breath caught in her throat. She saw what Sharma was seeing: the glistening, swollen pink flesh, the changed architecture of Clare’s cunt. It looked different. Hungrier.
“Fascinating,” Sharma murmured. She picked up a device—a clear, dual-pronged speculum attached by a wire to a small monitor. Without ceremony, she inserted it, twisting it open. Clare let out a sharp gasp, her hips bucking slightly.
“Try to remain still,” Sharma said, her tone devoid of empathy. She watched the monitor, where waveforms jumped and danced. She picked up another instrument, a smooth, black dildo made of some soft, shiny polymer. It was attached by more wires to the same console. “This measures tissue compliance and neural response.”
She pressed the blunt head against Clare’s opening. Clare’s body tensed, her thighs trembling. The head slipped in with a wet, yielding sound. Sharma pushed slowly, her eyes fixed on the monitor. Evie watched, transfixed by the obscene sight of the black silicone disappearing inch by inch into Clare’s body. It was clinical, horrifying, and yet, a deep, shameful part of her was aroused. Her own cock, half-hard since they entered this room, throbbed against her zipper.
“Your vaginal canal is demonstrating significant elastic rebound,” Sharma noted, as if commenting on the weather. She pushed the entire length of the dildo in, until the base was flush with Clare’s lips. Clare’s stomach quivered. Her own cock, lying thick against her belly, was fully erect now, a slick bead of pre-come pooling at the tip. “The lumen has expanded to accommodate without strain. Neural firing patterns indicate a highly sensitized state, a feedback loop geared for penetration.”
She began to move the dildo, a slow, in-and-out piston motion. The wet sounds were loud in the quiet room. Clare’s breath hitched. Her hands gripped the edges of the table, the metal groaning in protest.
“Stop,” Clare gritted out.
“I need a baseline of arousal response,” Sharma said flatly, continuing her rhythmic motion. Her eyes never left the monitor. “It’s integral to mapping the transformation’s stability.”
Evie couldn’t look away. Clare’s face was a turmoil of shame and involuntary pleasure. Her hips began to move in tiny, betraying circles, meeting the thrust of the synthetic intruder. A low moan escaped her clenched teeth.
“See here,” Sharma said, gesturing for Evie to come closer. Evie moved as if in a dream, her feet leaden. The monitor showed a frantic, spiking green line. “The pleasure centers are lit up like a metropolis. Her body is rewriting its own reward system. It’s spectacular.”
It’s spectacular.”
Sharma’s thumb pressed a chrome button on her console with a definitive click.
A low, hydraulic hum filled the room. Inside Clare, the black polymer of the dildo began to swell. It thickened first, a slow, relentless inflation that made Clare’s eyes fly open wide. Her cunt stretched obscenely around the growing girth, the lips pulled taut and gleaming.
“Oh, fuck,” Clare choked out, her back arching off the table.
The device didn’t stop. It grew longer, pushing deeper into her, an impossible invasion. Evie watched, mesmerized and horrified, as Clare’s flat stomach seemed to bulge slightly with the internal pressure. The dildo was now longer than any natural cock, tunneling into depths that shouldn’t exist. Clare’s whole body was trembling, a fine sweat breaking out on her skin.
“Remarkable,” Sharma breathed, her clinical façade cracking with pure wonder. She watched the monitors, her green eyes wide. “The peritoneal fold is accommodating. No tissue strain signals. It’s as if her anatomy is reconfiguring in real-time.”
“Take it out,” Clare gasped, but her voice was a weak thread. Her hips rolled, a helpless, grinding motion against the massive intrusion. Her own thick cock jerked against her stomach, leaking a steady stream of pre-come that slicked her skin.
Sharma ignored her. She pushed another button.
A new, deeper vibration emanated from the device, a buzz that seemed to resonate in Clare’s bones. It wasn’t just a surface thrum. It targeted something deep, a hidden cluster of nerves now awake and screaming. Clare’s plea dissolved into a raw, shattered scream.
Her clit-cock, already erect, reacted violently. It twitched, then pulsed, a jet of clear fluid shooting from the slit to splatter across her large breasts. The shaft darkened, veins standing out in stark relief. It looked angry, alive, and impossibly sensitive.
“There it is,” Sharma said, her voice hushed. “Direct somatic feedback. The neural pathways are completely intertwined.”
Clare was beyond speech. Her world had narrowed to the feeling of being fucked open by something inhuman and the electric riot from her own transformed flesh. Each deep, internal vibration made her cock jump and weep. Her hands scrabbled at the metal table, finding no purchase.
Evie stumbled forward, her own body humming with a sympathetic heat. “Clare!”
“Don’t touch her,” Sharma commanded, not looking away from her data. “I need to observe the peak response.”
The dildo vibrated harder, stretching Clare to a breathtaking width. Clare’s screams subsided into broken, rhythmic sobs. Every muscle in her thighs and abdomen was corded tight, but she was utterly impaled, unable to escape the machine’s exacting rhythm. Her cock swelled further, an aching, purple-headed monument to forced arousal.
Then, with a final, gut-deep convulsion that made the table legs screech against the floor, Clare came. It wasn’t an orgasm of pleasure, but a violent, total expulsion of sensation. Her cunt clenched wildly around the monstrous device, her asshole fluttering against cold steel. From her cock, a torrent of cum erupted in thick, desperate ropes that painted her chest and chin, hot and smelling sharply of salt and sex.
From her cock, a torrent of cum erupted in thick, desperate ropes that painted her chest and chin, hot and smelling sharply of salt and sex. The machine attached to the monitor let out a rapid, high-pitched series of beeps, the green line on the screen spiking into a jagged plateau. Dr. Sharma leaned in, her breath fogging the screen slightly. "Fascinating. The myotonic response is generating its own electrochemical cascade. The tissue isn't settling."
Even as Clare’s body shuddered through the last waves of her forced climax, the black polymer inside her began to move again. It was a slow, sinister inflation, thicker than before, the medial bulbs swelling in a sequenced pulse that forced a broken whimper from Clare’s throat. It pushed deeper, an endless, gliding penetration that made Evie’s own stomach clench in sympathetic horror. Clare’s eyes, glassy and unfocused, rolled back.
"Jesus, it's still going," Evie whispered, her voice cracking.
"It is responding to the endocrine flood released by the orgasm itself," Sharma said, her fingers tapping the console. "A positive feedback loop. The body is interpreting the stimulus as a directive for further adaptation." The dildo elongated, a silent, relentless invasion. Clare’s abdomen distended, a subtle but undeniable rounding under her sweat-slicked skin. The device was plumbing depths that had no right to exist, tunneling into a space that was being created in real-time by the serum’s ruthless logic.
Clare’s hand flailed, finding Evie’s wrist. Her grip was shockingly weak. "Evie… it’s… it’s so deep." Her voice was a slurry of awe and terror. Then it shifted, hardening into something raw and needy. "Don’t stop it. Please. It’s… it’s filling me. I can feel it in my fucking throat."
"Clare, no," Evie said, but the protest was thin.
"More," Clare begged, her head thrashing side to side on the steel table. "Just a little more. I can take it. I need it." Her other hand slid down her own body, fingers wrapping around the base of her own pulsing cock, stroking it in a filthy, syncopated rhythm with the machine's deep thrusts. "Fuck, Sharma, leave it in. Let it fucking break me."
Dr. Sharma watched the biometrics, her cool detachment finally showing a hairline fracture—a faint tension around her mouth. "Your sacral plexus is overloading. The cortical readouts are becoming erratic." She watched as Clare’s hips pistoned weakly, trying to fuck herself on the impossible length. "If we continue, the adaptation may become permanent in a… less navigable form. The body might seek to internalize the stimulus. To retain it."
"What the hell does that mean?" Evie demanded, terror cutting through her arousal.
"The serum follows desire, Miss Reed. It doesn't discern healthy limits. It only builds what it thinks you want."
Clare just moaned, "Please."
With a sharp, decisive motion, Dr. Sharma hit a button. A hydraulic hiss filled the room. The vibration ceased. The deep, penetrating pressure inside Clare began to withdraw.
"No!" Clare screamed, a raw, guttural sound of loss. Her body convulsed, trying to clamp down, to keep the invading length inside her. But the machine was inexorable. The slick, black polymer emerged slowly, inch after terrifying inch, glistening under the lab lights. It seemed to go on forever, a magician’s trick of flesh and silicone. Evie stared, her mind refusing to comprehend the sheer length of it as it slid from Clare’s gaping, flushed hole.
Two feet. More.
The final bulbous tip popped free with a wet, sucking plop that echoed in the sudden silence. Clare’s cunt remained obscenely open, a pulsating, dark pink maw that didn’t close. It simply quivered, contracting around nothing, dripping a mixture of her own fluids and the machine’s lubricant onto the steel table in a steady, shameful drip.
Clare sobbed, a shudder wracking her frame. Her hand still stroked her own cock, but it was a frantic, lost motion. She felt cavernous, empty in a way that carved right into her spine. The cool air of the lab against her ravaged, open flesh was a torture. She looked at Evie, her blue eyes swimming with a desperate, shattered hunger.
