Megan, a chemist at BodyCorp, suffered a lab accident with a penis growth drug. Shes torn between her orgasms being earthshatteringly amazing and her penis growing after each orgasm. Trying to date again, she meets Samson, who becomes amazed at his girlfriends growing dick.

Chapter 3: The Plan

The rain was still drumming a nervous rhythm against the windows when Megan turned back toward the couch. Sam’s expression had shifted from warm concern to guarded curiosity. The phone lay between them on the charger, a silent witness.

“Everything okay?” he asked, his voice careful.

The confession—I saw what you look at, and by the way—died on her lips. Instead, her mind, that brilliant, traitorous organ, executed a swift lateral calculation. Risk assessment. Exposure management. She needed time. Space to think. To understand what his search history meant, and what was happening to her body without the dizzying pressure of his proximity.

“Yeah, just… lab stuff,” she said, forcing a smile that felt like a cracked glaze. She walked back, but didn’t sit. She hovered by the arm of the couch, the distance feeling both necessary and vast. “Actually, it’s a mess. They’re sending me to that conference in Denver. The polymer symposium. Last minute. I leave tomorrow.”

It was a lie built from old, discarded plans. The conference had been months ago. Sam’s eyebrows lifted. “Tomorrow? For how long?”

“Two weeks,” she said, the number falling between them like a stone. She saw the disappointment flicker in his eyes, genuine and unguarded, and it made her chest ache. “I know. The timing sucks.”

He ran a hand through his hair, then nodded, accepting it. “Well, polymer symposiums wait for no woman. Send me boring pics of hotel ballrooms.”

“I will.” She needed to bridge the gap, to offer something to make the lie palatable, to tie him to her. The idea came, fully formed and reckless. “But when I get back… I was thinking. I have this cabin booked. Up near Big Bear. A proper weekend. No phones. Just… us.”

His face transformed, the disappointment evaporating into a bright, eager grin. “Really?”

“Yeah. As a… reunion.” The word felt heavy with implication.

“I’d love that,” he said, standing up. He didn’t kiss her again, just pulled her into a tight hug. She buried her face in his shoulder, inhaling the scent of ginger and cotton and him. Her body, so confused and wound, pressed against his, and she felt his residual arousal, and her own, a trapped, thickening presence between them. A feedback loop of secret knowledge.

“I’ll miss you,” he murmured into her hair.

“Me too,” she whispered, and it was the truest thing she’d said all night.

The next two weeks were a strange, suspended animation. Her “trip” was spent in the cage of her own apartment. She called in sick to the lab, citing a persistent flu. The world shrank to the dimensions of her chaotic living room and the glow of her laptop screen.

Sam texted daily. Funny observations, questions about her (fictional) talks, goodnight messages that made her skin hum. And true to a pattern she now understood, he sent another picture two days in.

It was less posed this time. A selfie taken in what looked like a gym locker room, his face slightly flushed from a workout, a towel around his neck. The angle was deliberate, thrillingly crude. His hand was wrapped around his thick, soft member. Missing you has its downsides, the caption read. Mostly this persistent ache.

The image was a punch of warmth to her gut. But now, alongside the arousal, was a new, analytical layer. She studied it not just with lust, but with a comparative eye. His was magnificent, a archetype of masculine endowment. Her breath hitched. Her own body, lounging in sweatpants with no underwear, responded instantly. She felt the familiar, insistent swell, the heavy pull of blood.

She didn’t touch herself. Not yet.

Instead, with a pulse thundering in her ears, she opened a new browser window. She typed in the URL she’d memorized, the one from his phone. The forum loaded. The banner art was unapologetic, garish. The Garden of Delights.

Her first reaction was a scientist’s disdain for the absurdity. The proportions were laughable, physiologically impossible. The women smiled with sharp, predatory glee as they wielded members thicker than their forearms. But as she scrolled, the clinical distance evaporated. The comments sections were a revelatory flood of adoration, worship, desperate longing. I’d give anything to be with a woman like that, one user wrote. The ultimate power, said another.

Her hand drifted down. She was fully hard now, her own cock—her cock—lying thick and hot against her thigh. It was nowhere near the fantasy dimensions on screen. But it was real. It was hers. And it was, according to Sam’s secret browsing, the object of a profound and specific desire.

A desire he didn’t know sat across from him at dinner.

A low, shaky breath escaped her. She clicked on a video. It was amateur, poorly lit. A woman with a shock of pink hair stroked a realistically-sized strap-on, then used it on a sighing, eager partner. The performance was awkward, the props obvious.

But the concept. The dynamic.

Megan’s hand closed around herself. The feeling was electric, a jolt that traveled straight to the base of her spine. She began to move her fist, a slow, experimental pump. Her eyes remained fixed on the screen, not on the exaggerated toy, but on the expressions. The focused intensity of the woman giving. The surrendered pleasure of the one receiving.

Her strokes became quicker, more urgent. The pleasure built, not from the friction alone, but from the dizzying, terrifying collision of images in her head: Sam’s generous, confident smile. The heavy weight of him in his photo. The lines of text praising impossible women. The feel of her own solid, living flesh in her hand, a secret truth growing in the dark.

She came with a choked-off cry, her back arching off the couch, vision whiting out at the edges. The climax was deeper, richer than any before, laced with a powerful, taboo current of identification. She wasn't just a woman getting off. She was, in that shattered moment, both of the people on the screen.

In the heavy, spent silence afterwards, the guilt was a quieter guest. It was edged out by a burgeoning, terrifying sense of possibility. And by a familiar, ominous sensation of expansion.

She didn’t need the tape measure. The proof was in the lingering, substantial fullness, the way it now curved noticeably against her belly even in its softening state. She measured anyway, later, in the steam of her shower.

6.3 centimeters.

The growth wasn't slowing. It was accelerating. The association was no longer just with orgasm, but with psychological immersion in the very idea of what she was becoming.

The cabin weekend loomed in her calendar, a bright red circle. A deadline. A point of no return. She bought new clothes online: simple men’s cotton boxer briefs in a dark grey, which held her more securely, comfortably. A pair of loose, soft linen trousers. She packed her secret journal, her measuring tape, a single, unlabeled vial from her fridge—the Emergency Growth Inhibitor (Probably Won’t Work). A totem of hopeless science.

The night before she was to “return” and pick him up, Sam sent a final text. Can’t wait for tomorrow. Cabin. You. Silence. Attached was one last image. It was just his face this time, smiling sleepily from his pillow. Pack warm, he wrote. I hear it’s cold in the mountains when you’re all alone.

She stared at his face, then down at her own body, clad in the new boxer briefs. The bulge was prominent, unambiguous. No longer something that could be hidden by a lucky drape of fabric. It was a shape. A fact.

She typed back, her fingers steady for the first time in weeks. I’m not planning on being alone. And don’t worry. I’ll bring the heat.

She hit send, the promise hanging in the digital air between them, a lie wrapped in a truth she still didn't fully understand. Outside, the city lights shimmered, but all she could see was the dark outline of mountains, and the deep, unknown quiet waiting for them there.

Outside, the city lights shimmered, but all she could see was the dark outline of mountains, and the deep, unknown quiet waiting for them there. A more immediate silence filled her apartment the next morning, brittle and heavy with decision. The cabin was booked for Friday. Today was Wednesday. She had lied about her return. This left forty-eight hours.

Forty-eight hours to try and control the uncontrollable. The “Emergency Growth Inhibitor” was a joke, a placebo of her own despair. She needed something substantive, something from the source. Her mind, trained for chemical solutions, locked onto a memory: BodyCorp’s ongoing trials. MuscoGrow for tissue hyperplasia. Elevator for chondrocyte acceleration in the epiphyseal plates. They were volatile, wildly experimental, and under lock and key in the Pharma Division vault. She knew the protocols. She also knew Darlene from Materials Management, who had a keycard and a pension fund she was desperate to fatten.

“It’s a simple bypass,” Megan said, her voice sounding too bright in the sterile hum of the lab’s break room. Darlene, a wiry woman with perpetually smudged eyeliner, stared into her coffee. “The logs are automated on a twelve-hour delay. We swipe in after hours, take two vials from the Beta shelf. They’ll think it was a calibration error.”

“You’ve lost your mind, Hayes.” Darlene didn’t look up. “That’s not simple. That’s career-ending. Federal crime-ending. What could you possibly need them for?”

The lie she prepared—a theoretical side project—withered on her tongue. The truth was a physical pressure, a thick, insistent presence confined by her trousers. She felt it stir, as if sensing the opportunity. A reckless, electric clarity took over. She leaned forward, her voice dropping.

“What do you think I need them for, Darlene?” Megan’s gaze was unflinching. “Look at me.”

Darlene finally looked. Really looked. At Megan’s heightened color, the new breadth of her shoulders straining the lab coat, the impossible, telling proportion of her stance. Her eyes widened, then flickered down briefly before snapping back to Megan’s face. “No way.”

“Way.” Megan’s pulse hammered in her throat. “The… accident. It’s ongoing. I need to modulate it, to study it properly. I can’t do that with the scraps in my fridge.” She saw the greed and fear warring in Darlene’s expression. The monetary offer wasn’t landing. Something else was needed. A darker currency. The words left her before she could cage them. “Help me. And I’ll… show you what it can do.”

The silence stretched, taut. Darlene’s cheeks flushed. “You’re talking crazy.”

“Am I?” Megan stood up, slowly. She guided Darlene’s hesitant hand, placing it against the front of her trousers. The firm, substantial heat beneath the cotton was unequivocal. Darlene yanked her hand back as if burned, but her breath hitched. Her curiosity was a palpable, thick thing in the room. “Two vials,” Megan whispered, the offer hanging between them, obscene and magnetic. “And you can have a private… demonstration. A full one.”

Darlene’s resolve crumpled. It wasn’t just the money. It was the terrifying allure of the secret. “Tonight. After ten. The cleaning bots cycle on the west wing then.”

The theft was a blur of stolen keycards and heart-pounding silence in the green-tinted glow of the secure pharma fridge. The vials were cold in Megan’s hand, labeled with stark, ominous serial numbers. In the shadowed parking garage, Darlene’s car idled. The “demonstration” was a frantic, clinical transaction in the back seat, leather seats creaking under them.

Megan fumbled with her fly, her cock springing free, thick and full in the dim light. Darlene made a small, choked sound, not of disgust, but of sheer awe. “Christ, Hayes.”

It was awkward, rushed, a means to an end. Megan pushed inside, her mind split. Part of her catalogued the stunning, wet heat, the way Darlene’s nails dug into her biceps. The other part was a roaring furnace of sensation, power, and profound alienation. She finished quickly, a shuddering release that felt more like a biological purge than pleasure. Darlene lay beneath her, panting, her eyes wide and glittering with a mix of triumph and shock. “Your secret’s safe,” she breathed, but it sounded like a threat.

Back in her apartment, Megan didn’t hesitate. The contents of the two vials were a viscous, pearlescent grey. She injected them consecutively into her thigh. The effect wasn’t immediate. For an hour, nothing. Then a deep, cellular ache began, a feeling of being gently torn apart and rewoven on a larger loom.

Her bones first. A low, grinding throb in her shins, her spine, her fingers. She watched, detached, as her hands lengthened subtly, knuckles repositioning. She stood against her height chart. The mark she’d made at 6’1” was now well below the crown of her head. 6’3”. 6’4”. The cartilage in her ears and nose itched furiously.

Then the muscle. It wasn’t a bodybuilder’s pumped distortion, but a dense, relentless expansion. Her shoulders broadened, delts rounding, traps thickening up her neck. Her quadriceps tightened the fabric of her sweats, her calves growing defined and hard. She stripped, standing before the full-length mirror on her closet door.

The woman reflected was a stranger. A powerful, formidable amazon. Her blonde hair seemed lighter against her now more pronounced jawline. And between her legs, the change was most profound. The organ was heavier, a substantial weight. She measured with cold fingers.

Eight and a half inches. Thick as her wrist.

A wave of dizziness passed through her, part awe, part terror. The drugs were working in concert with her original condition, amplifying it, escalating the timeline from months to hours. She packed for the cabin with mechanical movements, her new fingers clumsier on the zipper. She chose the loosest clothes she owned, but they pulled at her new shoulders, draped differently over her chest and hips.

She texted Sam. On my way. Her phone felt tiny in her palm.

When she pulled up to his curb, he was waiting with an overnight bag, his face breaking into that easy smile. It froze, then reconfigured into a puzzled grin as she stepped out of the car. He had to look up slightly now.

“Whoa. Denver air agrees with you,” he said, his eyes doing a quick, confused scan of her frame. “You look… taller? Did you hike?”

“Something like that,” Megan said, her voice slightly deeper, she noticed. She leaned in to hug him, a careful, calculated gesture. His body felt familiar, but the fit was different. She was enveloping him. She felt him stiffen for a fraction of a second as his hands pressed against the solid, unyielding muscle of her back.

“You feel really strong,” he muttered into her shoulder, a note of confusion giving way to something else. Awe? Intimidation?

“Let’s hit the road,” she said, pulling away before he could scrutinize her further. She loaded his bag, her movements fluid with new power. As they drove into the gathering dusk, the mountains ahead no longer symbolized a quiet unknown. They were a mirror. She was the unknown now, a seismic event contained within a rental car, heading into the dark to meet a man whose desire she thought she understood, carrying a secret that had just grown far too big to hide.

The silence in the car was a third passenger, dense and ticking. Sam kept glancing over, his fingers drumming a nervous rhythm on his knee. The headlights carved a tunnel through the pine-lined darkness.

“Seriously, Meg,” he finally said, his voice too casual. “What did they feed you at that conference? You look like you could deadlift this car.”

Megan’s grip tightened on the wheel. The rental’s leather seat groaned under her shifted weight. “Maybe I just finally used the hotel gym.” The lie was brittle.

“Your jawline’s different.” He reached out, his fingertips barely grazing her cheek. The touch sent a shock through her system, a confusing mix of affection and panic. She flinched. He pulled his hand back, a frown forming. “Okay. What’s going on?”

The cabin appeared then, a dark A-frame at the end of a gravel drive. She parked, the engine dying into a silence so complete it felt auditory. Crickets. The sigh of trees. The thud of her own heart.

“Let’s get inside,” she said, avoiding his question.

The key stuck. She turned it with a slight, wrenching force that made the lock mechanism click loudly. Sam followed with the bags, his presence a warm, questioning pressure at her back. She flicked the lights on, revealing a rustic space: exposed beams, a stone fireplace, one large bed dominating the room.

He dropped his bag by the door. “Megan.”

She turned. He was standing there, arms crossed, but his stance wasn’t angry. It was open, concerned. His earlier confusion had settled into a patient demand for truth. The kindness in his eyes undid her.

All her planned speeches vanished. The scientific explanations, the careful reveals—they crumbled to dust. There was only the weight of the secret, the physical truth of it, a unbearable pressure against her fly. She was so tired of carrying it alone.

“You’re right,” she said, her voice raw. “It wasn’t the conference.”

She crossed the room in two strides, the new power in her legs making the movement startlingly quick. Before he could speak, she kissed him. It wasn’t like their previous kisses—soft, exploratory. This was hunger, desperation, a claiming. She felt him gasp into her mouth, his body tensing for a second before melting against hers with a low groan. His hands came up, gripping her biceps, and she felt his fingers dig in, testing the new, dense muscle there.

She broke the kiss, breathing ragged. Her hands went to the hem of his shirt. “I need to see you,” she murmured, the words hot against his neck. “Right now.”

He nodded, dazed, and raised his arms. She pulled the soft cotton up and over his head, tossing it aside. In the warm cabin light, his chest was familiar, comforting. Her hands roamed his skin, rediscovering the landscape of him, as she led him backward toward the bed. He sat on the edge, watching her with dark, uncertain eyes.

She knelt on the rough wooden floor between his legs. Her fingers worked the button of his jeans, then the zipper. She eased them down over his hips. He kicked them off, and there he was, already half-hard, his cock laying thick against his thigh. It was just as magnificent as in the photos, a beautiful, known quantity.

She looked up at his face, then took him into her mouth without another word.

She moaned around him, the sound vibrating through both of them. The taste of him, the solid feel of his length on her tongue, was an anchor in the swirling storm of her reality. She worked him with a focused intensity, one hand cupping his balls, the other braced on his powerful thigh. She listened to every hitch in his breath, every stifled groan, using them as a map. This, at least, she could do. This was a language she still spoke.

“Megan… god,” he gasped, his hands tangling in her hair, not guiding, just holding on.

His hips bucked slightly. A warning. She increased her pace, taking him deeper, and with a sharp, broken cry, he came. She swallowed, the act feeling like a sacrament, a communion. A final moment of the old world.

She rested her forehead against his thigh, listening to his panting subside. The quiet returned, heavier now, charged with what came next. She could feel his softening cock slip from her lips.

Slowly, she stood up. The floorboards creaked under her new weight. Sam looked up at her, his expression sated, grateful, still clouded with that lingering confusion.

“Your turn,” he whispered, reaching for the button of her linen trousers.

She caught his hands. “Let me.”

Her fingers, now so much larger and stronger than he remembered, made quick work of her own clothes. The linen trousers pooled at her feet. The simple grey boxer briefs followed. She stood before him, utterly exposed, as the fire crackled in the hearth.

Sam’s breath stopped.

His eyes traveled upward from her feet, over the dense, powerful calves, the quadriceps like sculpted stone, the defined v-line cutting into her hips. They lingered on her stomach, now a rigid plane of abdominal muscle. They rose further, over the expansive chest, where her breasts, full and surprisingly pert, rested atop the sheer musculature. His gaze finally reached her face, now sharper, more angular, crowned by the wild fall of blonde hair.

“Jesus Christ,” he breathed, not in horror, but in pure, unadulterated astonishment.

Then his eyes snapped back down, locking onto the center of her. His mouth fell open.

Between her legs, jutting out from a thatch of blonde curls, was a cock of impossible dimension. It was fully, aggressively erect, a heavy shaft of flushed flesh that reached toward her navel, thick as his own wrist and far, far longer. The veins stood in stark relief, a network of powerful rivers under smooth skin. The head was a broad, leaking crown.

It was 14.6 inches of living, breathing truth.

Sam just stared. He didn’t recoil. He didn’t speak. His earlier awe crystallized into a single, fixed point of total, captivated focus. The man who loved being bigger, who sent those confident photos, was gone. In his place was someone transfixed, his own considerable endowment now completely forgotten, rendered irrelevant by the monumental reality of her.

He reached out a single, trembling hand, stopping an inch from the shining tip. His eyes were wide, his pupils blown black in the firelight.
