Chapter 33: Just a bit longer
The new length was a cold, hard fact between Clare’s legs. It hung heavier, a pendulum of her own making. The dull ache in her groin had subsided to a persistent throb, a reminder of the strain. She stared at Evie, whose face was a canvas of horror, not awe.
“You see?” Clare’s voice was tight, triumphant. “It’s not just happening to me. I’m directing it.”
“You’re mutilating yourself,” Evie breathed, scrambling off the bed. She grabbed a discarded t-shirt—Clare’s—and held it in front of herself like a shield. “That’s not control, Clare. That’s… self-harm with a new feature.”
“It’s adaptation.” Clare turned back to the mirror, her gaze critical. The new inches were slender, almost delicate compared to Evie’s brutish girth, but they were undeniable. She felt a fresh, prickling wave of arousal just looking at it. The power was the ultimate aphrodisiac. “It’s using what we’ve been given.”
“Given?” Evie’s laugh was sharp, almost a sob. “We didn’t get a gift basket, we got a fucking experimental serum injection! And you’re leaning into it!”
Clare ignored her. The analytical part of her brain was already running projections. If she could initiate growth through focused will, could she refine it? Could she control the rate? The shape? She envisioned the slender length thickening, becoming more substantial, more like the tool she suddenly, desperately craved it to be. She fixed her mind on the image, on the sensation of expansion, of filling out.
A tremor began deep within her pelvis. The slender shaft twitched. Then, slowly, it began to swell from within. It wasn’t just hardening; the actual circumference increased, the skin stretching, becoming taut and shiny. Veins grew more prominent, rising like relief maps on a growing landscape. It was thickening from the base upward, becoming more solid, more weighted.
“Stop it,” Evie whispered, but her voice lacked force. It was the plea of someone watching a car crash in slow motion, powerless.
Clare didn’t stop. She fed the process with her concentration, with the vivid memory of being inside Evie, of that sublime, stretching tightness. Her cock—her cock—continued to swell. It was no longer delicate. It was becoming respectable. Impressive. It was approaching the length and thickness of a natural, heavy erection, but it was hers, grown from a flicker of thought and a clot of need.
The pleasure of the growth itself was minimal; it was a feeling of intense, internal pressure, like a deep muscle being flexed beyond its limit. But the psychological reward was immense. She was rebuilding herself, on her terms.
When she let the mental command lapse, she was left with a fully hard, substantial penis. It was longer and thicker than anything nature had ever intended for her. It curved slightly upward, the head a dark, flushed plum. She wrapped her hand around it. The heat was shocking. The sense of ownership was total.
She turned from the mirror, her eyes landing on Evie. The fear in Evie’s eyes had been joined by something else—a dark, reluctant fascination. The pink hair was plastered to her forehead with sweat. Her own monstrous equipment lay semi-soft against her thigh, a dormant threat.
“It needs to be tested,” Clare said, her tone leaving no room for debate. “Properly. Not just a frantic fuck. A stress test.”
“What does that mean?” Evie asked, her voice small.
Clare crossed the room. The new weight between her legs shifted with each step, a foreign yet familiar rhythm. She stopped in front of Evie. “On your knees.”
A shiver ran through Evie. The part of her that had always yearned to please Clare, to bridge the gap she felt between them, bent before the part that was repulsed. She sank down, the hardwood unforgiving against her kneecaps. She stared at the new reality in front of her face. It loomed, smelling of salt and skin and that faint, unsettling copper tang.
“Take it in your mouth,” Clare instructed, her hand not guiding, just resting on her own hip. “Slowly. I want to feel every millimeter.”
Evie’s hands trembled as she reached out. Her fingers brushed the heated skin, and she felt it pulse in response. She leaned forward, her lips parting. The initial contact was smooth, almost silky. She took the head into her mouth, her tongue flattening against the slit. The taste was bitter, metallic.
“Deeper,” Clare commanded, her breath hitching only slightly.
Evie obeyed, sliding her mouth down the new length. It was an unfamiliar act from this angle, with this… tool. She had to open her jaw wider than ever before to accommodate the girth. She felt it press against the roof of her mouth, then the back of her throat. Her eyes watered.
Clare watched, a scientist observing a reaction. “Good. Now, you’re going to stay there. And you’re going to feel what I can do.”
Evie’s eyes, wide and streaming, looked up in confusion.
Clare closed her own eyes. She shut out the sight of Evie on her knees, shut out the room, shut out everything but the point of sensation where her flesh disappeared into wet, choking heat. She focused not on the pleasure of the suction, but on the mechanism of growth. She isolated the feeling, the mental ‘muscle’ she had discovered. And she flexed it.
Inside Evie’s mouth, the cock began to change.
It started with a hardening, a further solidifying that Evie felt immediately. Then came a subtle, insistent lengthening. The head, already nestled in her throat, pushed forward. Evie gagged, a violent reflex, but Clare’s hand came to the back of her head, fingers tangling in pink hair, holding her in place.
“Don’t pull away,” Clare murmured, her voice strained with concentration.
The shaft grew longer. It was a continuous, slow press, pushing deeper into Evie’s throat, stretching her esophagus open. Evie’s body convulsed, her hands flying up to clutch at Clare’s thighs, nails digging in. Guttural, choking sounds vibrated around the invading flesh. Tears streamed down her cheeks.
Clare was transcendent. The feeling of power was unimaginable. She was fucking Evie’s throat not with thrusts, but with her will. Each fraction of an inch of growth was a conquest. She could feel the tight, spasming resistance of Evie’s body around her, a perfect, living sheath being remodeled to her specifications. The physical sensation was intense, a constant, deep-throated pressure, but it was secondary to the triumph.
“It’s so deep,” Clare gasped, her own knees feeling weak. “I can feel your fucking heartbeat in my tip.”
Evie couldn’t speak. She could barely breathe. Her vision swam with black spots. The cock in her throat was still slowly, relentlessly lengthening, a thick, living cable she was being forced to take. The ache in her jaw was blinding.
Clare pushed the mental command further. She willed it wider.
The thickening was less graceful. It was a blunt expansion. The already-stretched tissues of Evie’s mouth and throat were forced outward. A sharp, tearing pain shot through Clare’s own groin—a warning—but she rode through it. The need to dominate, to fully utilize this awful gift, was too strong.
Evie made a desperate, animal sound. A string of saliva and pre-come dripped from her stretched lips onto the floor. Her grip on Clare’s thighs went limp.
Sensing the edge, Clare finally released the mental pressure. The growth stopped. She was buried to what felt like the root in Evie’s convulsing throat. She held there for a long, terrifying moment, savoring the absolute fullness, the utter control.
Then, with a wet, sucking gasp, she pulled Evie off by her hair.
Evie collapsed forward onto her hands, coughing violently, ropes of spit and phlegm hanging from her mouth. She vomited a little, a thin, clear bile that splattered on the floor between her trembling palms. She drew in huge, ragged breaths, sobbing.
Clare looked down at her own cock, glistening with Evie’s saliva and tears. It was now long, thick, and painfully hard. A engineered implement. A perfectly calibrated weapon of pleasure and submission.
She felt no remorse. Only a hungry, echoing void. The test was successful. The capability was proven.
But the deep, throbbing pain in her pelvis had not faded. It had solidified into a sharp, persistent sting with every heartbeat. She ignored it, reaching down to stroke her own magnificent, terrifying creation.
“See?” Clare said to the shuddering form at her feet, her voice eerily calm. “I told you. We just needed to understand the rules.”
From outside, the first sounds of the city waking up filtered in—a distant garbage truck, a car alarm. The normal world was proceeding, minute by minute. In the room, the only rules that mattered were the ones Clare was writing with her own flesh, and the cost was etched in Evie’s tear-streaked face and the new, worrying pain gnawing at Clare’s core.
In the room, the only rules that mattered were the ones Clare was writing with her own flesh, and the cost was etched in Evie’s tear-streaked face and the new, worrying pain gnawing at Clare’s core. Clare dismissed them both. The pain was just data. Evie’s distress was static.
“Watch this,” Clare said, her voice a low monotone of concentration.
She ignored Evie’s choked protests from the floor. Closing her eyes, she focused past the raw ache in her pelvis, past the sick pride. She isolated the mental trigger again, that specific, internal flex. She imagined a slow, relentless extrusion, a lengthening that had no endpoint. She fed the image with sheer will, a cold, calculated push against the limits of her own biology.
Beneath her fingers, her cock twitched.
It wasn’t the urgent thickening from before. This was a slower, more deliberate transformation. The already impressive length began to extend further. It grew past its previous state, the skin stretching taut like glossy latex over the new, underlying hardness. Clare’s hand, which had been resting at the base, had to slide downward to encompass the fresh growth.
Evie watched from her hands and knees, her breath still ragged. A thread of saliva still connected her lips to the floor. Her eyes, red-rimmed and wet, tracked the movement of Clare’s hand. There was a deep-seated horror there, a betrayal. But beneath it, pulsing like a weak vein, was an awful, captivated curiosity.
She was seeing the serum’s potential fully unleashed, directed by a mind that lacked all restraint.
“Fuck,” Evie whispered, the word torn from her bruised throat.
Clare didn’t acknowledge her. Her entire world was the sensation under her palm. Each incremental centimeter of growth was a victory. She stroked from root to tip, her grip firm. Her strokes were short at first, encompassing the familiar length. But as the shaft continued its silent, steady extension, her hand had to travel farther.
The strokes became longer. She watched her own fist glide over newly formed flesh, a pioneer claiming uncharted territory. The head grew more pronounced, a smooth, plum-dark cap. Pre-come beaded at the slit, a clear, viscous testament to the mutation’s functionality.
It was now longer than any natural erection had a right to be. It hung heavy, a pale, thick rope of living flesh that reached past her mid-thigh. The weight of it was a delicious anchor. The pain in her groin had transformed, mutating into a bright, singing strain that felt like triumph.
“Clare, for god’s sake,” Evie croaked, finally pushing herself up to sit back on her heels. She wiped her mouth with the back of her hand. “Look at it. It’s… it’s obscene.”
“It’s mine,” Clare corrected, her eyes finally snapping open. They were glassy with focus. “I decided this.” Her next stroke was a long, possessive pull from the very base, now low on her pelvis, all the way to the newly forged tip. The motion was smooth, audacious. She was marveling at her own reach.
She turned slightly, letting the lamplight catch the sheen on her lengthened shaft. The sight of it, this impossible appendage, sent a fresh jolt of ownership through her. She wanted to see its full potential. She wanted to map its limits.
“Come here,” Clare said, not looking at Evie. “Touch it,” Clare instructed. “Feel what I made.”
Hesitantly, Evie raised a hand. Her fingertips, cold and trembling, brushed against the side. The skin was hot, almost feverish. It was solid, unyielding. She let her hand cup the ridiculous weight of it, her smaller fingers unable to fully circle the girth. A drop of clear fluid leaked onto her wrist.
“It’s warm,” Evie murmured, her clinical observation a thin shield for her revulsion.
“It’s me.” She placed her own hand over Evie’s, forcing her grip tighter. “Now stroke it. With me.”
Clare began the motion again, a long, slow pull from root to tip, forcing Evie’s hand to move along with hers. Evie’s touch was reluctant at first, a ghost of pressure. But as Clare set the rhythm, as she whispered “harder,” and “feel it,” Evie’s resistance crumbled into a numb compliance. Her hand began to move in tandem, her own grip firming.
They stroked her together, a perverse partnership. The rhythm was hypnotic, a ceremony worshipping the mutation. Clare’s breath came in shallow pants. Each pass of their combined hands was a revelation of texture, of heat, of sheer outrageous mass.
Evie’s hand stopped moving. She stared at the shaft in their hands, a tool of terrifying possibility. Clare’s earlier penetration had been a brutal claiming. The thought of being taken by this new, engineered length was something else entirely. It promised a violation that was surgical, profound.
Clare felt the hesitation. She misinterpreted it. She saw it as a challenge.
With a grunt of effort, Clare redoubled her mental focus. The cocktail of pain and power crested. She pushed.
The growth, which had slowed, resumed with a sudden, jarring lurch. An extra inch, then two, violently stretched into existence. The skin strained, shiny and tight. A sharp, tearing sensation ripped through Clare’s lower abdomen, so acute she cried out—a short, sharp sound of shock and victory.
Evie jerked her hand back as if burned. Clare’s cock now hung down, the tip brushing her own knee. It was a ludicrous, horrifying length. The strokes of her hand were absurdly long now, a full, sweeping motion from her pelvis down the grand expanse of shaft.
Clare threw her head back, her eyes squeezed shut. The pain was blinding, white-hot, but it was fused with a conquering ecstasy. She was the author and the subject, the cause and the effect. She was rewriting the story of her own body, one agonizing, glorious inch at a time.
She was rewriting the story of her own body, one agonizing, glorious inch at a time. The pain in her pelvis was a bright, buzzing wire, but it was drowned by the roaring in her skull that said more, further, mine. She opened her eyes, her gaze locking onto Evie’s horrified face. “You see?” Clare panted, her voice raw. “It doesn’t have to be a curse. It can be a choice.”
Evie just stared at the monstrous length swinging heavily between Clare’s thighs. It was a ludicrous, pale rope of flesh, veined and gleaming under the harsh morning light bleeding through the blinds. Her throat was still a raw, bruised tunnel from earlier. “It looks like it hurts,” she whispered.
“Everything worthwhile hurts a little.” Clare’s smile was a tight, grim line. Her hand resumed its long, possessive stroke, a grotesque petting of her own creation.“Come here. I want you to taste it again. I want you to feel how deep it can go now.”
“Clare, no, I can’t,” Evie stammered, scrambling backward until her shoulders hit the bed frame. “My throat… you’ll fucking rupture something.”
“You healed from the last time, didn’t you?” Clare took a step forward, the movement awkward with the new, pendulous weight. “That’s part of this.We heal fast. We adapt. Now get up.” The command was brittle, a lawyer’s closing argument leaving no room for appeal.
Evie’s body moved before her mind consented, a conditioned response to Clare’s authority. She rose on shaky legs, her own neglected cock a heavy, dull ache against her leg. She was wet, she realized with a spike of shame. A slick, traitorous heat had gathered between her thighs despite the fear, because of the fear.
Clare saw it. Her eyes flicked down, noting the gleam on Evie’s inner thighs. “See?” she murmured, stepping closer until the hot, solid tip of her pressed against Evie’s stomach. It left a damp smear. “Your body knows what it wants. It’s smarter than you are.”
She curled a hand around the nape of Evie’s neck, not gentle. Her other hand guided the immense, slick head of her cock to Evie’s lips. The pre-come was copious, salty and metallic. “Open,” Clare said, and it wasn’t a request.
Evie opened her mouth, a small, reluctant ‘o’. Clare pushed forward. The initial stretch was immediate, brutal. Evie’s jaw protested as the thick crown forced its way past her teeth. She gagged, her eyes watering anew. Clare didn’t stop. She fed the length in with a slow, relentless pressure, watching Evie’s face contort.
“That’s it,” Clare breathed, her own breath hitching as the tight, wet heat enveloped her.“Take it. All of it.”
It was impossible. There was simply too much of it. Clare kept pushing, and the shaft, obscenely long, began to fill Evie’s mouth, then press deep into her throat. Evie’s hands flew up, gripping Clare’s forearms, her nails digging half-moons into the skin. Her choking sounds were wet, desperate music.
Clare’s head fell back, a low groan tearing from her. The sensation was unimaginable. She was buried in a tight, convulsing channel, a living sheath made solely for her invasion. She could feel every spasm of Evie’s gag reflex, every clench of her trachea against the invading tip. It was deeper than any touch had ever been, a profound and violent intimacy.
“I can feel your heartbeat,” Clare moaned, her hips giving a small, involuntary thrust, sinking another impossible half-inch deeper. Evie’s body jerked, a suffocated scream vibrating around the flesh filling her.
Clare’s control was a thin veneer now, cracking under the tsunami of sensation. The clinical observation, the power trip, it all began to blur into something base and animal. The pain in her groin was a distant thrum, absorbed into a gathering tidal wave of pressure low in her belly. Her thrusts became less measured, more frantic. She fucked Evie’s throat in short, savage jabs, the wet, slapping sounds of her pelvis meeting Evie’s face filling the room.
Evie’s vision darkened at the edges. Black spots danced. Her grip on Clare’s arms loosened, her hands falling limply to her sides. She was a vessel, a used thing, her body violating itself to accommodate this horror. A strange, numb acceptance washed over her. This was what they were now. This was the equation.
Clare felt the submission, the utter surrender in the lack of resistance. It was the final trigger. The coiled tension in her core snapped.
A violent, wrenching spasm tore through her. It wasn't a localized climax, not just her new, monstrous cock pulsing. It was a full-system seizure. Her back arched sharply, a strangled cry ripped from her throat. The lengthy shaft in Evie's mouth throbbed wildly, jetting hot, bitter fluid in erratic bursts down Evie's violated esophagus.
But simultaneously, from her forgotten, neglected vagina, a different release erupted. A gush of thick, milky fluid spurted out in a sudden, shocking torrent. It wasn't the clear ejaculate from her cock; this was heavier, opaque, and it flooded down her inner thighs with startling warmth, dripping onto the floor between their feet. The dual release was overwhelming, a confusing riot of sensations from two separate centers, an ownership that was suddenly, terrifyingly incomplete.
The spasms wracked her, endless and brutal. She slumped forward, her weight collapsing onto Evie, who crumpled beneath her, both of them falling in a tangled, wet heap to the hardwood floor. Clare’s exaggerated length slipped from Evie’s mouth with a sick, wet pop.
For a long moment, there was only the sound of ragged, choked breathing. Evie sucked in air in great, whooping gasps, her body curled fetal. Clare lay half on top of her, spent, shaking, staring blankly at the wall. The warm, strange fluid from her vagina soaked through both their thighs, a sticky, cooling puddle.
Clare’s hand moved, trembling, to touch the wetness on her own leg. She lifted her fingers, staring at the opaque fluid. Her face, a mask of triumphant exertion moments before, slackened into pure, uncomprehending confusion.
“What,” she whispered, her voice hollow, “was that?”
