Gemma

Chapter 4: Size Matters

The growth wasn’t incremental anymore. It was geological. Time moved in a blur of sweat-damp sheets and aching fullness. Blake’s apartment became a shrine to a single, overwhelming fact.

Gemma would stand, and it would hang there, a heavy pendulum of flesh that brushed mid-thigh. When she lay on her back, it rose from her pelvis like the trunk of a young tree, the head a broad, smooth dome that nestled just above her navel. The veins were road maps of a foreign country, raised and tributaried. She’d gotten used to the weight, the constant, low-grade awareness of it. Getting dressed was an engineering problem. Walking required a slight, adjusted gait. Sitting was an event.

Blake worshipped it with a mixture of terror and devotion. His hands, once so large, now looked almost childish trying to span her girth. His mouth, which had once taken her so easily, now strained, his jaw clicking, tears of effort leaking from the corners of his eyes as he tried to accommodate her. He’d choke, pull back gasping, and dive in again, driven by a need that had long since curdled past simple attraction into something darker.

“I can’t,” he’d rasp one evening, on his knees before her as she stood by his futon. He’d been trying for ten minutes, making pathetic, gagging sounds. A string of saliva connected his lower lip to her glans. “I can’t even get half.”

“You asked for this,” Gemma said, not unkindly. It was just truth. Her voice had changed, too; it carried a lower, more resonant register, a calm that felt immovable.

“I know.” He looked up at her, his eyes red. “Help me.”

He meant the other way. His preferred way, now. She’d obliged him, countless times. But the act had transformed. It was no longer a frantic, hidden inversion. It was a slow, methodical claiming. Blake would prepare himself with a focus that was almost meditative, slicking himself with more gel than seemed necessary, his fingers working in a nervous, frantic rhythm. He was never ready.

When she pushed into him, it was with an inexorable, steady pressure. His body fought a losing battle. His breath came in short, pained whimpers that would slowly morph into a low, continuous moan as she seated herself fully inside him, a process that took minutes. She’d feel his internal heat, the desperate clench of muscles trying to adapt to an impossible circumference. She was ruining him, and he loved it. He’d come, untouched, from the sheer, overwhelming stretch, his cries muffled by the pillow. She’d fuck him through it, her own orgasm a deep, tectonic event that would make her grow another fraction, stretching him further, making him sob with overstimulated pleasure.

Afterwards, he’d walk funny for days. He wore it like a secret badge.

One Friday, the air in the apartment thick with the smell of sex and microwaved noodles, Blake could barely sit. He moved around the kitchenette like a man who’d been kicked in the spine. Gemma watched from the futon, a strange fondness twisting in her chest. He’d asked for a monster, and she’d become one. It was his masterpiece, as he’d said. And he was its most faithful victim.

“Party at Sigma Tau,” he said, wincing as he lowered himself onto a stool. “The whole team’s going. Jeremy’s been… asking again.”

Gemma felt a familiar curl of anticipation. Jeremy. The name had buzzed in the background for weeks, a persistent hum. “Asking what?”

“If you’re real. What you’re like.” Blake wouldn’t meet her eyes. “I might have… shown him a picture. From before. When you were… smaller.”

“You what?”

“Just one! From weeks ago!” He defended himself, but the guilt was plain. “He didn’t believe me. He said it was photoshop. Called me a liar.” The wounded pride in his voice was sharp. “You should come. Show him.”

Gemma understood. This wasn’t just about Jeremy’ interest. This was Blake’s bruised ego seeking validation, wanting to weaponize her existence against a rival. She stood up, the movement causing her to sway slightly with the shift in weight. “Okay.”

The Sigma Tau house was a looming Victorian gone to seed, pulsing with bass from within. The basement was a cave of damp concrete and neon LED strips, the air a solid mass of beer fumes, body spray, and the sweet, acrid tang of vaped nicotine. A deflated pool table was an island in a sea of plastic cups. Jeremy Dillon was holding court near the keg, a mountain of a man. He was taller than Blake, broader, with a linebacker’s thick neck and a smile that was all easy, confident charm. His eyes scanned the room and landed on Blake, then flicked to Gemma. The smile didn’t fade, but it changed, becoming more specific.

“Samson!” Jeremy boomed, cutting through the noise. “You made it. And you brought the legend.” His gaze traveled down Gemma’s body, lingering with an appraisal that was neither lewd nor shy. It was calculating.

“Jeremy, this is Gemma,” Blake said, his voice tight.

“I know who she is.” Jeremy extended a hand. His grip was crushing, intentional. “Heard a lot. Most of it hard to believe.”

“Believe what you want,” Gemma said, extracting her hand.

“Oh, I’m a see-it-to-believe-it guy.” He took a slow sip from his cup, his eyes never leaving hers. “Blake here says you’ve got a piece that puts us all to shame. Says it’s fucking unreal.”

A few guys nearby tuned in, smirking. A bet, then. Not just curiosity. Theatre.

“Blake talks too much,” Gemma said.

“He does,” Jeremy agreed, amiably. “So. Settle it for us?”

Blake was tense beside her, vibrating with a mix of dread and excitement. This was his show. Gemma felt the heavy throb between her legs, a steady pulse of potential. She looked at Jeremy, at his wide, arrogant face, the sheer physical dominance he wore so casually. She imagined that confidence cracking.

“Your room,” she said, not a question.

Jeremy’s smile widened. He led the way, a few of his buddies—other large, grinning athletes—trailing behind like a pack of curious hyenas. Blake followed, his face pale.

Jeremy’s room was a monastic cell for a giant: a bare mattress on a frame, weights in the corner, a single poster of a muscle car. It smelled of cheap detergent and athletic sweat. He kicked the door shut behind the small crowd, leaning against it. “Well. Let’s see the myth.”

The room fell silent. All eyes were on her. Gemma unbuttoned her jeans. The denim, already strained, fell open. She didn’t push them down. She just freed herself, letting it spring out into the cool, stale air of the room.

The reaction was not the hungry awe of Blake, or the delighted avarice of Daisy. It was a collective, sharp intake of breath, a moment of stunned silence broken by a muttered, “Holy fuck.”

Jeremy’s easy smile froze. His eyes, previously amused, sharpened. He pushed off the door and took a step closer. He stared. It was a frank, competitive assessment. He was comparing.

Without a word, he undid his own belt, pushed his jeans and boxer briefs down. He was already half-hard, and the reveal was impressive. Blake hadn’t exaggerated. Jeremy was huge. Thick as a wrist, and long. A legitimate, breathtaking piece of male anatomy. A king among men.

But as he grew fully erect under the neon light, the comparison became undeniable. He was substantial. But Gemma was… monumental. The length was comparable, perhaps an inch in it either way. The girth, however, was not. She was wider, heavier, a dense column of flesh that made his impressive member look almost streamlined.

A deep, unpleasant flush crept up Jeremy’s neck. The confidence in his eyes flickered, replaced by a shocked, furious calculation. He’d expected to be the bigger man. He was built to be the bigger man. It was the core of his identity in this room, on the field, everywhere.

“Well,” he said finally, the word tight. “Guess Blake wasn’t lying.”

One of his friends whistled low. “Dude. She’s got you by a mile.”

Jeremy’s jaw clenched. The pack mentality shifted, subtly, turning against its alpha. He was being dethroned in front of his court. He looked at Gemma, and the humiliation in his eyes was molten. But beneath it, something else glinted. A raw, desperate need.

“Get out,” he said to his friends, not taking his eyes off Gemma.

“Aw, come on, Jere—”

“Get the fuck out!” he roared. The room cleared, Blake lingering for a second before Jeremy’s glare sent him scurrying too. The door clicked shut.

They were alone. The silence was a physical thing.

Jeremy stared at her cock, his own still jutting out, defiant and now hopelessly outclassed. “How.” It wasn’t a question.

“It grows,” Gemma said simply.

“Bullshit.”

“Try me.”

He crossed the room in two strides. There was no reverence, no worship. It was a challenge. He dropped to his knees, his big hands grasping her base. He looked up at her, his expression fierce. “You think this intimidates me?”

“I think it does,” Gemma said.

He snarled and took her into his mouth. It was nothing like Blake’s desperate attempts or Daisy’s playful worship. This was an act of violence, a war fought with lips and tongue. He was trying to conquer her, to master the thing that had shamed him. He gagged immediately, his eyes watering, but he forced himself deeper, using his hands to push. It was brutal, clumsy, and wildly effective. The sheer, aggressive determination sent shocks of pleasure straight to Gemma’s core.

He pulled off, gasping, saliva coating his chin. “See?” he rasped. “Not so tough.”

“You didn’t make me come.”

His eyes flashed. He dove back in, with a furious, rhythmic intensity. He was strong, with relentless stamina. He found a brutal, punishing pace, his nose buried in her pubic bone, his throat working convulsively. Gemma let her head fall back against the wall. This wasn’t pleasure; it was a power struggle, and it was making her harder than she’d ever been.

She felt the climax build, a slow, rising tsunami. “That’s it,” Jeremy muttered against her, feeling her tremble. “Come for me, you freak. Let’s see this magic trick.”

The word ‘freak’ did it. The orgasm exploded from her, a wave of such intense, shocking power that her knees buckled. She cried out, gripping his hair as she pulsed into his mouth. He took it, swallowing convulsively, his hands squeezing her thighs hard enough to bruise.

As the waves subsided, he stayed there, his forehead pressed against her stomach, breathing hard. Then he felt it. The gradual, undeniable swell. The thickening in his grasp,

the lengthening against his cheek. He jerked back as if scalded, staring at the now-even-more-substantial weight in his hands. His breath hitched.

He stood up abruptly, his own erection flagging slightly from shock. He stepped closer, aligning their bodies side-by-side in the mirror tacked to his wall. He scrutinized the reflection, his eyes measuring.

A slow, relieved grin spread across his face. “See?” he said, the arrogance seeping back into his voice. “I’ve still got an inch on you. At least.”

Gemma glanced at the mirror. He was right, in a narrow, technical sense. The head of his cock still peeked just a fraction beyond hers when measured tip to tip. But the difference was negligible, a silly vanity. She noted silently, with cold clarity, that she was thicker by a far more significant margin, a dense reality he seemed willfully to ignore. She didn’t say a word.

The grin turned predatory. “Guess that means I still win.” His hands landed on her hips, turning her away from the mirror with a rough spin. He pushed her forward, bending her over the foot of his bare mattress. “My prize.”

He didn’t wait, didn’t prepare her. There was just the blunt, burning pressure of him, huge and impatient, and then a single, brutal shove that seated him to the hilt. Gemma cried out, her fingers clawing at the fitted sheet, the pain a bright, splitting star that instantly melted into a devastating, full-bodied pleasure. He was impossibly big, stretching her in a profound and different way, claiming a territory Blake never could.

“Yeah, moan for it,” Jeremy grunted, setting a punishing, athletic rhythm immediately. Each drive knocked the breath from her lungs. “You might be a freak, but you’re still underneath me.”

And she was. Gemma let her forehead rest on the mattress, her body rocking under his onslaught. She moaned, long and loud, not in submission but in pure, stunned sensation. He was right. He did win this. For now.

Afterwards, he collapsed beside her, smug and spent. “Told you,” he panted.

Their partnership became a regular, secret thing. He’d text her with a time and a room number, often in different frat houses or off-campus apartments he had keys to. The encounters were always the same: a tense, wordless comparison against a wall or in a streaked bathroom mirror, his eyes searching for that reassuring inch of lead, followed by a fierce, competitive coupling where he always took her from behind, as if the position itself reinforced his narrative of dominance.

He wanted to measure her again, often. “Come on, let’s see how much that weird little trick added,” he’d say, reaching for her.

Gemma always swatted his hand away, rolling out of bed. “It’s not a trick,” she’d say, pulling on her jeans with a casualness she didn’t feel. “And no. It’s creepy.”

She knew exactly what the measurements would show. In the quiet of Daisy’s bathroom, with the door locked, she’d confirmed it. Flaccid, she was now a full two inches longer than Jeremy’s impressive erect length, and undeniably thicker. The knowledge was a secret coal, glowing hot in her chest. She guarded it fiercely.

She loved watching him strut, basking in the illusion of his supremacy. She loved the hungry way his eyes followed her when she dressed, the way he’d still call her a freak with a tone that had become oddly affectionate. She loved, most of all, the moment of stunned helplessness in his eyes every time she came, feeling herself swell fractionally inside him or against his tongue, a growth he could feel but was never permitted to quantify.

The balance was perfect, and utterly fragile. He had his inch. She had the truth, and all the power that came with waiting.

The power was a quiet, humming thing. It lived in the knowing. Gemma carried it with her across campus, a secret gravity that changed her posture. She’d catch her reflection in library windows—a tall, blonde girl in loose jeans and a hoodie, nothing special. But she knew. The disconnect was thrilling, then unnerving. Her body felt like a specialist’s tool, a precision instrument for one overwhelming purpose. It was out of balance.

She looked top-light. The sheer, pendulous weight between her legs demanded ballast. It needed an anchor.

So she started eating. Not the cautious salads of before, but deliberate, protein-heavy meals she tracked on her phone. Chicken, rice, avocados, shakes that tasted like chalk. She ate until her stomach felt tight and full, a new kind of fullness. Softness returned to her hips, her belly, a layer of padding over the sharp angles. It felt protective. Substantial.

Then she went back to the gym for the first time since high school. The university rec center smelled of chlorine and stale sweat. She avoided the free weights where Jeremy’s crew might be, sticking to the quieter resistance machines at first. She set the pins, braced herself, and pushed.

The progress wasn’t gradual. It was alarming.

The muscle memory was there, but supercharged. A latent strength, deep and coiled, answered every demand. On the leg press, she doubled her starting weight in a week. The sled moved like it was empty. When she moved to squats, the bar across her shoulders felt like a toy. She watched in the foggy mirrors as her quadriceps hardened into distinct, corded shapes with each rep. Deltoids pushed against the straps of her tank top. Triceps defined themselves when she reached for her water bottle.

Her body was rebuilding itself around a new center of gravity. She wasn’t just getting stronger; she was becoming dense. Each new cut of muscle was a counterweight to the heavy, impossible mass below her waist. She’d finish a set, breathing hard, and feel a profound, integrated solidity she’d never known. She was becoming a single, powerful unit.

Jeremy noticed the changes, but he misunderstood them entirely.

“Getting soft, Smith?” he sneered one afternoon, his big hand patting her now-solid stomach through her shirt in a dark corner of the Kappa Sigma basement. His tone was teasing, meant to diminish. He saw the new weight as a feminine concession, a softening. He didn’t see the hard lines beneath it.

“Just comfortable,” she shrugged, knocking his hand away.

“You should come lift with me. For real. Get some definition back.” He flexed his own arm unconsciously, the biceps straining his sleeve. He still saw her as a project, a freakish challenge to be managed within his world.

“I’m good.”

His eyes darkened, dropping to her crotch. The real contest, for him, was always there. “Let’s check your progress then. It’s been a couple weeks.”

His hand darted for her button fly. This was his ritual, his needed reassurance.

Gemma caught his wrist, her grip far stronger than it had been a month ago. He looked surprised, then irritated. “No.”

“Why not? Scared I’ve finally outpaced you?” He leaned in, his breath smelling of cheap beer. “Scared my little inch is still winning?”

“It’s not a race, Jeremy.”

“Everything’s a race.” He echoed Daisy’s words, but with a brittle, competitive edge. “Prove it’s not.”

She released his wrist, but didn’t move to undo her jeans. Instead, she stepped into him, forcing him back against the stained pool table. She kissed him, hard, biting his lower lip. “You want to measure something?” she whispered against his mouth, her hand sliding down to cup him through his chinos. He was already hard. “Measure this.”

She used his own fervor against him, every time. His lust was a predictable, potent fuel. He hated the mystery, the not-knowing. It gnawed at his arrogance. So he’d try to conquer the uncertainty with sheer physical effort, fucking her with a brutal, athletic stamina that left bruises, or swallowing her down with a grim determination that made his eyes water. He was trying to dominate a mystery, and the frenzy of his attempts only fed the very thing he feared.

Afterwards, he’d lie beside her, spent and slick with sweat, his hand automatically, possessively, falling to her stomach. “You feel bigger,” he’d mumble, half-asleep, his fingers tracing the new layer of flesh over the hardening abs beneath.

“You’re imagining things.”

“Am I?” He’d prop himself up on an elbow, his gaze wary. “It feels thicker in my hands.”

“Maybe your hands are getting smaller.”

He’d scowl, a flash of genuine anger. But he couldn’t prove anything. She never let him line them up side-by-side anymore, never gave him the mirror again. His evidence was haptic, subjective: a fuller grasp, a heavier hang against his thigh when she rolled atop him, a tighter, more impossible stretch when he took her inside himself in moments of abject, secret craving.

Her time would come to crush him. To end the fiction of his “little inch” forever, to break that arrogant smile with the sheer, undeniable reality of her. She dreamed of the look on his face when the last vestige of his superiority shattered.

But the growth he was giving her in the meantime was intoxicating. Each of his frustrated, competitive orgasms—whether from her hand, her mouth, or the increasingly rare times he could muster the ego to be inside her—pumped another raw dose of expansion into her. She could feel it happening in real time, a deep, cellular unfurling that was both pleasure and profound change.

It was a drug. And he was her unwitting, feverish dealer.

The collision happened on a Tuesday. Gemma was at the gym late, under the harsh fluorescent lights of the nearly empty weight room. She was deadlifting. The plates were stacked high, a serious weight that would have made her old self gasp. She wrapped her hands, set her stance, back straight. The pull was smooth, a powerful ascent that brought her to her full height, the bar grazing her thighs. She held it at the top, muscles in her back and legs singing, a statue of exerted force.

She didn’t hear the door. She only saw his reflection materialize behind her in the mirror, frozen, watching.

Jeremy. He was in his practice gear, a gym bag slung over his shoulder. He was just standing there, his face blank. He was watching the way the weight moved, the clear, uncomplicated power of it. He was watching the definition in her traps, the column of her neck, the way her new muscles handled the load.

But his eyes weren’t on her back. They were locked lower, on the pronounced, heavy bulge straining against the front of her compression shorts. The shorts were old, from before. They were meant to contain, to minimize. They were failing spectacularly. The outline was unmistakable, a staggering, soft weight that the powerful rise of the deadlift did nothing to obscure. It was a juxtaposition that made no sense: fierce, masculine strength above, and a staggering, supernatural endowment below.

Gemma lowered the bar, the plates crashing with a finality that echoed in the quiet room. She turned around, breathing heavily, meeting his stare.

He didn’t speak. The usual arrogant quip died in his throat. His gaze was stuck, cycling between her face, her shoulders, and the blatant, impossible evidence in her shorts. The illusion he’d been clinging to—of a soft girl with a party trick—evaporated in the sterile gym light. Here was something else. Something built.

She picked up her towel, wiped her neck. “See something you like?”

He finally blinked, the spell breaking. A deep, angry red bloomed up from his collar. The confusion in his eyes hardened into a defensive, hot fury. “What the hell are you doing?”

“Deadlifting. It’s good for the core.”

“You know what I mean.” He gestured at her, a crude, sweeping motion. “All of… this.”

“Just trying to keep up,” she said, and she meant it in every possible way.

He crossed the space between them in three long strides, stopping too close. The air crackled. He wasn’t trying to seduce her now. This was a confrontation. “Let’s settle it. Right now.”

“Settle what?”

“This! This fucking… competition!” His voice was low, strained. “You and me. No more games. We measure. For real.”

Gemma smiled then, a slow, calm thing. She tossed her towel over her shoulder. The momentum was hers now, a tangible force in the room. She could feel the truth of herself, the dense muscle, the terrifying weight, the secret inches she knew she had on him. The waiting was over.

“Okay,” she said, her voice quiet. “Your place.”
