Chapter 2: More and More
The dorm room door clicked shut behind Riley, sealing them in with the scent of pepperoni and the low thrum of the mini-fridge. Kate leaned against the sink, the cool porcelain the only solid thing in a world tilting sideways. Riley munched her pizza, oblivious, recounting some political theory debate. Kate’s skin still buzzed from… from it. The phantom weight, the slick warmth, the earth-shattering pulses of release. It felt branded onto her nerves.
"Yeah," Kate managed, pushing off the sink, forcing her legs to carry her towards her desk. "Brutal." Her voice sounded thin. "Squats. Lunges. Felt like my legs were gonna liquefy." She pulled out her desk chair, the scrape loud in the small room. Sitting felt perilous. The denim pressed against her, a constant, insistent reminder of the secret nestled beneath. Was it still… noticeable? She subtly shifted.
Riley grinned, licking grease from her thumb. "Heroic. I stuck to the elliptical. Less… liquefying potential." She glanced at Kate, her green eyes sharp. "Seriously though, you look wrecked. More than just legs." Her gaze lingered for a second too long on Kate's flushed face. "Shower didn't help?"
Kate's hand flew to her cheek, self-consciously scrubbing at nonexistent sweat. "Steam maybe. Hot." She busied herself opening her laptop, the screen glowing to life. "Just tired. Need to crank out this chem lab report." It was a flimsy shield. The molecules on the screen swam before her eyes, meaningless symbols. All she could feel was the subtle throb between her legs, a low pulse echoing the frantic beat of her heart. Did it get harder again? Just thinking about it?
Stop thinking about it.
She squeezed her eyes shut for a millisecond, trying to focus on electron configurations. Impossible. The memory of her own hand, the friction, the explosion… heat flooded her core. A tiny, involuntary sound escaped her lips – a soft gasp she barely registered.
Riley paused mid-bite, pizza slice hovering. "You sure you're okay?"
"Fine!" Kate snapped, sharper than intended. She winced. "Sorry. Just… headache starting." She rubbed her temples, avoiding Riley's gaze. The silence stretched, thick with unspoken questions. Riley slowly lowered her pizza.
Kate’s fingers flew over the keyboard, typing gibberish. The pressure inside her was building again, insistent, undeniable. That deep, demanding throb she hadn't known existed a day ago. It was worse than before, a physical ache radiating from her groin, tightening her stomach muscles. She shifted again in the chair, trying to find a position where the seam of her jeans didn't press so… there. It was useless. Every movement seemed to amplify the sensation. She crossed her legs tightly, pressing her thighs together. Just finish the report. Ignore it.
But the throb deepened, became a molten pull. Images flashed: the shower spray, her hand gripping warm flesh, the blinding release. Her breath hitched. She squeezed her legs tighter, pressing the heel of her hand hard against her crotch through the denim. A desperate attempt to quell the fire. A low groan vibrated in her chest, muffled.
"Kate?" Riley’s voice was closer now. She’d gotten up. "That doesn't sound like a headache."
Kate froze, hand still pressed hard between her legs. She couldn't look up. Shame burned her face. "I'm fine. Just… cramp." The lie was pathetic.
Silence. Then the sound of Riley taking another step. Curiosity warring with concern. "Cramp where?"
Panic flared, white-hot. Kate scrambled for a response, anything. "Leg! Hamstring. From… squats." She tried to flex her leg, a jerky, unconvincing movement. Her hand remained clamped where it was, the pressure the only thing holding back the rising tide.
Riley didn't move. Kate could feel her presence, a tangible weight inches away. The air crackled. Kate kept her head down, staring blindly at chemical formulas, willing Riley to believe the lie, to walk away. Please walk away.
But Riley didn't. She crouched down beside Kate’s chair, her movement fluid. Her long black hair brushed Kate’s bare arm. Kate flinched.
"Kate," Riley murmured, her voice low, impossibly close. "Look at me."
Terror locked Kate's muscles. She couldn't. She kept her gaze nailed to the screen, her knuckles white where she gripped the edge of the desk. Her breath came in short, ragged bursts. The throbbing between her legs was a drumbeat now, demanding, consuming. She pressed her hand harder, grinding her palm down.
"Your hand," Riley said, her voice husky. Not disgusted. Not shocked. Intrigued. "It's not on your leg."
Kate's world stopped. The frantic typing. The buzzing fridge. Riley’s quiet breathing beside her. All sound vanished, replaced by the deafening rush of blood in her ears. The secret was out. Exposed. There was no hiding now. A choked sob escaped her.
Slowly, trembling violently, Kate turned her head. Riley’s face was inches away. Her green eyes weren't wide with horror. They were dilated, dark pools of intense curiosity, locked onto Kate’s hand, pressed firmly over the undeniable bulge straining against her jeans. Riley’s lips were slightly parted. There was no mistaking the flush on her cheeks.
"You're not… cramping," Riley whispered. It wasn't a question. Her gaze flicked up, meeting Kate’s terrified blue eyes. "Are you?"
Kate shook her head mutely, tears welling. Humiliation warred with the relentless, terrifying ache radiating from her core. "I… I don't…" she stammered, voice cracking. "Riley, I…"
Riley didn't flinch. Didn't recoil. Her expression was pure, focused fascination. "Can I see?" The question was barely audible, a breath against Kate’s skin.
Kate recoiled. "No! God, no! It's… it's disgusting! It shouldn't be there! I don't understand!" The words tumbled out, frantic, desperate. She tried to pull her hand away, to cover herself properly, but the movement shifted the denim, making the outline even more pronounced. A fresh wave of shame crashed over her.
Riley reached out. Not to touch Kate between the legs, but to gently cover Kate’s trembling hand where it still rested. Her touch was warm, steadying. "Disgusting?" Riley echoed, her voice still low, but firm now. "It's part of you. It's… right there." Her thumb stroked the back of Kate’s hand. "Show me. Please."
The combination of Riley’s unwavering gaze, the warmth of her hand, and the agonizing pressure inside Kate shattered her resistance. A whimper escaped her lips. She couldn't fight it anymore. The need to release the unbearable tension, the terrifying urge to be seen, collided violently. Her eyes squeezed shut. Slowly, hesitantly, she lifted her hand away from her jeans.
The bulge was unmistakable. Thick. Straining against the denim. A stark outline impossible to misinterpret.
Riley’s breath hitched. Kate braced for revulsion, for screaming, for the end of everything. But Riley didn't move. Her hand, still covering Kate’s, pressed down slightly, feeling the solid ridge beneath the fabric.
"Jesus," Riley breathed, the word laden with awe, not horror. Her gaze traveled slowly down Kate’s body, over the tight jeans, then back up to her face. "How long?"
"Shower," Kate choked out, eyes still shut. "Yesterday. It just… appeared. Small. Then… bigger. I don't know why! I didn't… I didn't want this!" Tears spilled over, tracking hot down her cheeks. "I touched it… and…" She couldn't finish. Couldn't admit to the overwhelming pleasure, the shameful addiction already forming.
Riley was silent for a long moment, processing. Her thumb continued its slow stroke on Kate’s hand. "You touched it," she repeated softly. "How did it feel?"
The directness of the question punched through Kate’s panic. "I…" she stammered, shocked. "It… intense. Too much. Good. Scary good." The confession burned. "I couldn't stop. Before you came back. I…" She trailed off, mortified.
Riley shifted. Her other hand rose, trembling slightly, and hovered just above the straining denim bulge. "Can I?" She asked, her voice thick. "Touch it? Through your jeans?"
Kate’s entire body tensed. This was insanity. Riley wanted to touch it? The fear was still there, cold and sharp, but beneath it, a hot, treacherous surge of desire ignited. The throb intensified, seeming to pulse directly into Riley’s hovering palm. The memory of her own touch, the explosive release… She was starving for it. Her hips shifted forward almost imperceptibly. An invitation. A surrender.
"Yes," Kate whispered, the word barely audible.
Riley’s fingers brushed the denim. Tentative at first. Tracing the hard outline. Then, slowly, firmly, she palmed Kate through the fabric. Her touch was electric. Kate gasped, her back arching off the chair. It was different. Infinitely different from her own hand. Riley’s touch sent jolts of pure sensation radiating outwards, more intense, more overwhelming. A low moan tore from Kate’s throat, completely unrestrained this time.
Riley watched her, eyes dark with hunger, her own breath coming faster. "God, Kate," she murmured. "You’re hard." She squeezed gently, exploring the shape, the solid heat beneath the denim. Her thumb found the head, pressing deliberately.
Kate cried out, her hips bucking upwards involuntarily into Riley’s hand. "Riley! Oh god!"
The dam broke. Riley leaned in, her lips finding Kate’s neck, biting softly. "Show me," she breathed against Kate’s skin, her free hand fumbling for Kate’s zipper. "Let me see it. Let me feel it properly."
Kate was beyond thought, beyond shame. The need was primal, consuming. She helped, hands shaking, pushing the button through, dragging the zipper down. Together, they tugged her jeans and underwear down past her hips, just enough. Her cock sprang free, thick and flushed, fully erect now, standing proudly against her stomach. Precum beaded at the tip, glistening.
Riley stared. Her green eyes raked over it, wide with fascination, a flicker of pure possessiveness in their depths. "Oh, wow," she breathed, her voice husky. "Kate… it’s amazing." She didn't hesitate. Her hand wrapped around the shaft, skin on skin this time. Hot. Real. Her fingers closed firmly.
The sensation was blinding. Kate cried out again, throwing her head back. Riley’s grip was perfect, confident. She stroked, base to tip, her thumb swirling over the slick head. Her touch wasn't tentative; it was knowing, demanding. She leaned in, capturing Kate’s mouth in a fierce, open kiss. Kate kissed back desperately, tasting pepperoni and Riley, her hands tangling in Riley’s long black hair.
Riley broke the kiss, panting, her gaze burning into Kate’s. "Lie back," she commanded softly, pushing Kate’s chair back from the desk. Kate scrambled to obey, half-standing, half-falling onto her narrow bed. Riley followed, kneeling between Kate’s legs. She pushed the jeans and underwear down further, exposing Kate completely. Her gaze devoured Kate’s cock, her flushed folds beneath.
"Beautiful," Riley murmured, almost to herself. She leaned down, her long hair brushing Kate’s inner thighs. Kate tensed, expecting… something. But Riley bypassed her cock entirely, her mouth instead finding Kate’s clit, kissing, sucking with practiced intensity.
The dual assault was overwhelming. Riley’s hot mouth on her sensitive clit, her hand still firmly stroking Kate’s cock. Sensation crashed over Kate in relentless waves. She writhed, gasping, fingers clawing at the sheets. "Oh God, Riley! Yes! Please!"
Riley hummed against her, the vibration shattering Kate further. Her hand sped up, twisting slightly on the upstroke, her thumb pressing rhythmically under the head where Kate was most sensitive. Kate felt the pressure building impossibly fast, hotter, tighter than before, coiling deep in her belly, spreading fire through her limbs. She was dimly aware of Riley lifting her head, shifting her body.
Riley knelt up. She pulled her own loose shirt over her head in one fluid motion, revealing her large, heavy breasts, pale skin glowing in the dim room light. She didn’t remove her bra. Instead, she leaned forward, pressing those incredible breasts around Kate’s hard cock, trapping it in a hot, soft vise.
Kate gasped, stunned. The contrast – the slick, hard shaft engulfed in soft, yielding warmth – was indescribably good. Riley squeezed her breasts together, creating delicious friction as she moved up and down, using her cleavage to stroke Kate’s cock. Her eyes locked onto Kate’s face, watching every reaction with fierce intensity. Her fingers found Kate’s clit again, rubbing firm circles.
"Come on, Kate," Riley whispered, her voice rough. "Let me see it. Come for me."
It was too much. The visual, the sensations, Riley’s command. The coil snapped. Kate arched off the bed with a guttural cry, her vision whiting out. Her cock pulsed violently, jerking between Riley’s breasts. Thick ropes of cum shot out, striping Riley’s skin, her bra, landing hot on her collarbone. Wave after wave tore through Kate, more powerful than any orgasm before, ripping sounds from her throat she didn’t recognize. She pulsed and spurted, helpless, lost in the blinding ecstasy.
Slowly, tremulously, the intensity faded. Kate collapsed back onto the bed, gasping, trembling from head to toe. Spent. Utterly wrecked. Riley slowed her movements, then stilled, releasing Kate’s softening cock gently. Kate’s cum glistened on Riley’s skin and white lace bra. Riley looked down at herself, then at Kate’s limp form, a slow, satisfied smile spreading across her face. Not repulsed. Triumphant.
She leaned over Kate, one hand braced on the bed near Kate’s shoulder. Her green eyes, dark and fathomless, held Kate’s dazed gaze. Riley lowered her head, her lips brushing Kate’s ear. Her whisper was soft, intimate, vibrating with a fierce intensity that sent a fresh, different kind of shiver down Kate’s spine:
"Just wait," Riley breathed, her voice thick with promise, her warm lips grazing Kate's earlobe. "Just wait until I make it bigger."
The echo of Riley’s promise – Just wait until I make it bigger – vibrated in Kate’s bones long after the dorm room air cooled. It tangled with the scent of sex and pepperoni, a confusing, terrifying thrill. Sleep was impossible. Every brush of the sheet against her softening cock sent fresh jolts of awareness, a constant reminder of the impossible thing now part of her. Riley slept curled beside her, a possessive arm draped over Kate’s waist, her breathing deep and satisfied. Kate stared at the ceiling, tracing cracks in the plaster with her eyes. Shame warred with a terrifying, addictive hunger. Riley hadn’t recoiled. She’d wanted it. Craved it, even. That knowledge was a live wire, sparking something deep inside Kate that felt less like fear and more like… anticipation.
Morning brought a fragile normalcy. Riley acted like nothing monumental had happened, chatting about classes while pulling on leggings. Kate moved cautiously, dressing in loose sweats, hyper-aware of the unfamiliar weight between her legs, thankfully flaccid and less noticeable now. "Gym?" Riley asked casually, tying her hair back. "Leg day redemption?" Kate nodded, grateful for the distraction. The familiar burn of exertion, the clang of weights – that was solid ground. Something she understood. She needed to sweat out the confusion, the lingering phantom pulses of pleasure Riley had wrung from her.
The campus gym became Kate’s sanctuary. She threw herself into routines with a ferocity that bordered on punishment. Squats deeper, deadlifts heavier, sprints faster. Muscles screamed, lungs burned. It was glorious agony. Anything to drown out the insistent thrum that started low in her belly whenever she thought too long about the shower stall, Riley’s hands, her own desperate release. She chased exhaustion like a drug. Riley joined her most days, initially mirroring Kate’s intensity, her green eyes tracking Kate’s movements with an unnerving focus. "Damn, Kate," Riley panted after a brutal set of lunges, leaning against the rack. "You’re pushing like something’s chasing you." Kate just grunted, wiping sweat from her brow, refusing to meet Riley’s knowing gaze. It is, she thought grimly. It absolutely is.
Months bled together. Autumn leaves gave way to the brittle gray of winter, then the tentative green of spring. Kate’s physique transformed further – shoulders broader, quads sharply defined, abs like carved stone beneath her sports bra. Her blonde hair was perpetually damp at the temples. The relentless workouts did provide a buffer, a physical outlet for the restless energy coiling inside her. Yet, the distraction was never complete. The low throb persisted, a constant companion beneath the ache of well-used muscles. It flared unexpectedly: catching Riley’s reflection in the gym mirrors as she bent over a bench press, the heavy scent of male sweat near the free weights, the simple friction of her leggings during a long run. Each time, she’d push harder, faster, desperate to outpace it.
Riley’s transformation was quieter, but undeniable. She wasn't just toning; her body was reshaping itself with a peculiar, almost unsettling focus. Her already impressive breasts seemed heavier, fuller, straining against the reinforced fabric of her sports bras, drawing glances she seemed to relish. Her hips widened subtly, her waist cinching tighter, creating an exaggerated, lush curve that looked sculpted rather than earned solely through squats. She moved with a new, languid confidence. "These leggings are fighting me," Riley laughed one afternoon in the locker room, wrestling with the spandex clinging to her thicker thighs and rounded backside. Kate watched, towel-drying her short hair, a strange mix of admiration and unease twisting in her gut. Riley caught her looking and winked. "All this protein powder, huh?" Kate forced a smile, turning away. It wasn't just protein. It felt… deliberate. Purposeful. Like Riley’s body was answering some silent command Kate herself didn't understand.
The locker room post-workout was Kate’s most vulnerable moment. Showering was a tense ritual. She’d face the wall, water scalding hot, soap slicking over skin taut with fatigue. Her hand would inevitably drift lower, tracing the now-familiar shape nestled in her blonde curls. It was bigger. Undeniably. Thicker at the base, heavier in her palm. The initial two-inch surprise had steadily grown, pushing past four inches when fully hard – which happened far too easily now. Touching it sent immediate, electric shocks through her system. She’d bite her lip, stifling moans, torn between the desperate need for release and the fear of someone hearing, of Riley walking in again. The memory of Riley’s hands, her mouth, her breasts… it fueled the fire. Often, she’d give in, gripping herself under the spray, hips jerking silently, cumming hard and fast with a shuddering intensity that left her trembling against the cool tiles. Shame followed, sharp and cold, mingling with the lingering aftershocks. Yet, the hunger always returned, quicker each time.
One humid May afternoon, the air thick with the scent of cut grass and exertion, they collapsed onto adjacent benches after a grueling session. Kate’s muscles felt like liquid lead, her skin slick with sweat. She leaned forward, elbows on knees, sucking in deep breaths. The familiar ache bloomed low in her core, a persistent counterpoint to the glorious fatigue. Riley stretched languidly beside her, the movement emphasizing the dramatic swell of her chest, the curve of her waist flaring into newly prominent hips. She watched Kate, a slow smile playing on her lips. Kate felt the weight of that gaze, the unspoken knowledge humming between them. Riley leaned closer, her voice a low murmur barely audible over the clatter of weights and grunts echoing in the vast space. Her breath was warm against Kate’s sweat-dampened ear. "All that hard work," Riley whispered, her tone thick with a satisfaction that went far beyond the gym. "It’s really paying off, Kate. You’re growing so well." The words landed like a physical touch, reigniting the low throb into a demanding pulse. Kate froze, the post-workout haze evaporating instantly, replaced by a fresh wave of heat and the terrifying echo of that first night. Just wait until I make it bigger.
