Chapter 4: Reciprocal Hunger
The wet footprints they left on the rubber-matted floor were enormous, smeared signatures of their new scale. The weight room was quieter now, the late-night die-hards having thinned out. But the few who remained froze mid-rep.
A kid on the leg press let the sled crash down with a resonant boom. A man spotting his friend on the bench press forgot his duty, his hands hovering in the air as his jaw went slack. All eyes tracked Brian and Marcus as they moved back into the fluorescent glare.
They were different. Not just bigger, but altered. Their shoulders seemed to eclipse the overhead lights, casting deep shadows across their faces. The seams of their workout clothes, which had fit loosely hours before, now strained over newly thickened arms, across denser chests. They moved with a ponderous, deliberate grace, each step a declaration of mass.
“Don’t look at them,” Brian muttered, his voice a low rumble that felt unfamiliar in his own throat. “Just act normal.”
“Normal,” Marcus echoed, a hoarse laugh catching in his chest. He flexed his hand, watching the forearm muscle bulge like a nested fist. “Right.”
They gravitated towards a heavy-duty power rack, a solid island of steel in the center of the room. It was their usual spot, but it looked flimsier now. Brian loaded plates onto the bar, the 45-pound disks seeming lighter, less significant. He lost count, stacking them until the bar bowed slightly in the middle. The metallic clangs were the only sound in the hushed room.
Then, a different sound. A muffled, tinny repetition. A video playing on a phone.
Brian turned his head slowly. Across the gym, a guy in a tank top was staring at his screen, one hand gripping his phone, the other tucked into the waistband of his shorts. His eyes were wide, flicking from the phone to Brian and Marcus, then back again. His mouth hung open.
Another phone lit up, a few feet away. Then another. A soft chorus of gasps and stifled curses rippled through the space. The video was spreading. The kid had sent it to Jake, and Jake had sent it to the group chat, and now it was blooming across the room like a digital infection.
It played on a loop. That shaky, damning footage. The sounds of straining fabric. The guttural, undeniable sounds they had made.
The atmosphere curdled, then transformed. The initial shock melted into something hotter, thicker. Primal. The sharp scent of chlorine from the showers still clung to them, but underneath it was something else: a musky, pungent pheromone that seemed to broadcast directly into the lizard brain of every man present. It was the smell of raw, unfiltered growth. Of transformation. Of power.
The man on the bench press didn’t get up. He lay there, the bar resting on his chest, as his spotter’s hand drifted from the air to his own crotch, rubbing slowly through the fabric of his sweats. The kid on the leg press leaned back, his hand moving in a rhythmic, desperate shamelessness inside his shorts, his eyes glued to Marcus’s colossal back.
Brian felt their stares like physical touches. It wasn’t admiration anymore. It was hunger. A desperate, consuming need to touch the source, to partake.
“They’re fucking animals,” Marcus whispered, but there was no disgust in his voice. There was a dark, thrilling pride.
“Just lift,” Brian said, his own blood beginning to heat again. The hunger, so recently satisfied, was a sleeping beast easily poked. The charged air was poking it.
He laid back on the bench. The weight he’d loaded was over seven hundred pounds. It should have felt impossible. It felt like a warm-up. He gripped the bar, the knuckles of his hands like boulders. He took a breath that expanded his ribcage to an alarming degree, and pressed.
The bar flew up. No grind, no struggle. It moved as if propelled by hydraulics. He held it at the top, the monstrous weight locked out over his throat, the steel trembling not from his strain but from the sheer, unbalanced mass. He lowered it slowly, controlling the descent with a symphony of contracting muscle fibers, until it touched the thick meat of his chest. Then he pressed it up again. Easy. Five reps. Ten.
A low, collective groan went through the watchers. It wasn’t for the weight. It was for the display. The raw, impossible physics of it. Brian sat up, not even breathing hard. He looked over at Marcus.
Marcus was staring not at him, but at a figure lurking by the cable machines. David. The middle-aged, perpetually-cardio guy. He was pale, his fingers gripping a gym bag so tight his knuckles were white. He wasn’t watching a phone. He was watching Brian. His expression was one of sheer, unconcealed longing, mixed with a terror that seemed to root him to the spot.
Brian stood up. The room seemed to tilt around him. He could smell David from here—the clean soap, the faint trace of laundry detergent, the acrid tang of fear-sweat. And beneath that, a sweet, wanting ache. Brian started towards him, his footsteps echoing in the sudden quiet.
David didn’t run. He shrunk, trying to make himself smaller against the machine.
“You see something you like?” Brian’s voice was quiet, but it carried.
David flinched. He opened his mouth, but no sound came out. He gave a shaky, almost imperceptible nod.
From behind Brian, Marcus let out a low chuckle. “He’s been watching you for weeks, Brian. Like a little ghost.”
Brian stopped in front of David, blotting out the light. He could see every pore on the man’s frightened face, the rapid flutter of a pulse in his throat. “You want to touch?”
David’s breath hitched. He nodded again, a quick, shameful jerk of his head.
“Then touch.”
Brian took David’s wrist. The man’s arm was slim, fragile in his grasp. He placed David’s trembling hand flat on the center of his own pec. The muscle was rock-hard, fever-warm, and throbbing with a slow, powerful rhythm under the skin.
David gasped. His fingers flexed, timid at first, then greedy, kneading the impossible density. A choked sound escaped him. “How…” he whispered.
“Doesn’t matter,” Brian said. He was hardening in his shorts, a thick, urgent pressure against the fabric. The hunger was back, fully awake now, and it had a new focus. He saw the effect he had—not just on David, but on the whole room. It was a drug. He was the drug.
He pulled David away from the machine, leading him not to the showers, but to the flat, open space before the mirrors. He wanted them all to see. “On your knees.”
David didn’t hesitate. He sank down, his gym bag dropping with a soft thud. His hands went to the waistband of Brian’s shorts, fumbling with the drawstring. When he pulled them down, Brian’s cock sprang free, fully erect, thicker and heavier than before. David stared at it with a kind of religious awe.
Then he leaned forward and took it into his mouth.
It wasn’t skilled. It was messy, desperate, worshipful. David gagged immediately, his eyes watering, but he didn’t pull back. He pushed forward, taking more, his throat working convulsively. He slurped and gagged, his hands clinging to Brian’s tree-trunk thighs for balance.
Brian looked over David’s head into the mirror. His own reflection was a stranger—a gargantuan statue of flesh and power. And behind him, the audience. Every man in the room was motionless, transfixed. Some had their hands in their pants, openly stroking themselves. Others just watched, breath held, drinks forgotten. On one phone, still held aloft, the video played silently, a pale echo of the real thing happening live.
Marcus walked up beside him, his own erection straining against his shorts. He put a massive hand on Brian’s shoulder, his fingers digging in possessively. “Fuck his throat,” Marcus breathed, his voice thick. “Make him feel it.”
Brian obeyed. He placed his hands on either side of David’s head, not guiding, but holding. He began to thrust, short, brutal pumps into the wet, tight heat of the man’s mouth. David choked, tears streaming down his face, but he took it, his own hands fumbling to open his own pants, to touch himself as he was used.
“Yeah, just like that,” Marcus growled. He was rubbing himself through his shorts now, a slow, vicious rhythm. “Look at him. He’d let you break his jaw for a taste of it. They all would.”
Brian fucked David’s face with a rhythmic, mechanical intensity. The sensation was secondary to the display, to the sheer ownership of it. He was giving them a show, feeding the room’s new, hungry dynamic. David was just a vessel. A symbol.
When Brian came, it was with a roar that shook the mirrors on the walls. He pulled David’s head tight against him and emptied himself in deep, pulsing waves down the man’s throat. David swallowed convulsively, making soft, wet, drowning sounds.
Brian let him go. David collapsed onto his side, coughing, his lips glistening, his own orgasm splattered across the gym floor between his legs. He looked dazed, broken, fulfilled.
Panting, Brian pulled his shorts up. He looked around the silent, staring room. No one moved. The phones had stopped playing the video. The only sound was the hum of the lights and the ragged sound of David’s breathing.
Marcus clapped a hand on Brian’s back, the slap echoing. “Now they know,” he said, his voice carrying to every corner. “Now they all fucking know.”
But as Brian scanned the faces—awestruck, terrified, aroused—he saw something else. He saw the video was still there, cached in their devices. He saw the kid who filmed it wasn’t here. And he saw the door to the gym, a rectangle of streetlight, standing unlocked. The secret was no longer theirs. It was leaking out into the world, and the world, he understood with a cold, certain dread, would come looking for a taste.
The hunger inside him, momentarily sated, yawned wide again. It was no longer just a personal craving. It had become something else. An infection. And he was patient zero.
The silence that followed Marcus’s pronouncement was dense, choked with the scent of sweat, cum, and a new, collective hunger. It lasted only a second.
Then the room broke.
It started with the spotter, the one whose hand had been in his pants. He let out a strangled sound, half-groan, half-whimper, and simply walked forward. He didn’t look at Brian or Marcus’s faces. His eyes were locked on the thick outline of Marcus’s cock straining against his shorts. “I need…” he mumbled, reaching out.
Marcus caught his wrist with a speed that blurred. “You need to get on your fucking knees first,” he said, his voice a gravelly command. The man sank down instantly, his hands fumbling for Marcus’s waistband. As he pulled the fabric down, freeing Marcus’s erection, a shudder ran through the small crowd.
It was the permission they’d been waiting for.
The kid from the leg press stood up, his own shorts tented. He looked dazed, driven by a instinct deeper than fear. He moved towards Brian, his hands shaking. “Can I… just touch it? Your arm?” he asked, his voice cracking.
Brian looked down at him, this scrawny teenager whose video had started it all. A cold part of him wanted to break the kid’s neck. The hungry part, the part that was swelling again, thickening his cock against his thigh, saw only a vessel. “Touch,” Brian said.
The kid’s hands, damp and unsure, palmed Brian’s bicep. He gasped at the density, the heat. His other hand went to his own cock, stroking frantically through his shorts. Others followed. They came not as a mob, but as a hesitant, single-file line of desperate men. The weight room, moments ago a temple of solitary effort, became a confessional of shared need.
A man in his fifties, with salt-and-pepper hair and a slight paunch, knelt beside David, who was still panting on the floor. Without a word, the older man leaned down and began lapping at the mess on David’s stomach, his tongue seeking every drop. David moaned, his back arching.
Brian found himself surrounded. Hands were on him everywhere—kneading his deltoids, gripping his latissimus dorsi, tracing the deep canyon of his spinal erectors. Their touches were reverent and frantic. He was a monument, and they were pilgrims. One man, bearded and broad-shouldered, pressed his face against Brian’s lower back, inhaling deeply before his tongue lashed out to taste the sweat there.
“Get it wet,” Marcus ordered from nearby. He had the spotter’s head pinned between his thighs, fucking into his mouth with short, brutal strokes. “Get all of it wet. I want to feel every slick fucking hand.”
The instruction was a spark in dry tinder. Mouths found skin. Tongues, clumsy and eager, slid over pecs, across swollen abdominals, down the grooves of hips. Brian looked over and saw the bearded man now on his knees, his mouth working desperately on Brian’s balls, sucking one then the other with a hungry, slurping intensity. The sensation was electric, a direct current feeding the furnace in his gut.
He grabbed the kid by the hair, pulling him off his arm. “Open,” Brian grunted. The kid complied, eyes rolling back as Brian shoved three thick fingers into his mouth, coating them in spit. Then Brian turned him around, pushed him over the smooth padding of a nearby incline bench. He used the wet fingers to probe the kid’s tight hole, a crude, quick preparation. The kid yelped, his body tensing.
“Relax or I’ll split you in half,” Brian muttered, lining himself up. He didn’t wait. He drove forward, sheathing himself in a single, punishing thrust. The kid screamed, a high-pitched sound of shock and pain that was swallowed by the grunts and wet noises filling the room. Brian held there, buried to the hilt, feeling the boy’s body clutch and spasm around him. Then he started to move.
It was nothing like with Marcus. This was pure taking. A claiming. Each snap of his hips slammed the kid’s slender frame into the bench. The kid’s cries became choked sobs, then whimpers of a different kind. His own small cock, trapped against the vinyl, began to leak in tiny, helpless spurts.
Marcus had moved on. He’d pulled the spotter off his cock and was now bent over the leg press sled, the man’s face pressed into the cold metal. Marcus spat into his own hand, slicked his shaft, and plunged into him. The man’s roar was muffled by steel. Marcus fucked him with a mechanistic, piston-like rhythm, one hand braced on the machine, the other gripping the back of the man’s neck. His own back muscles coiled and released like a predatory animal feeding.
Brian came inside the kid with a guttural shout, his fingers leaving bruises on the boy’s hips. He pulled out, his cock glistening and still rigid, unsatisfied. The hunger was a vortex now, pulling everything into it. He saw the older man who had licked David clean now crawling towards him on his hands and knees, his mouth open like a baby bird’s.
“Please,” the man begged, his eyes glassy. “I need it. I need what you have.”
Brian understood. They weren’t just after sex. They were after the change. They’d seen the video, they’d witnessed the growth, and they wanted to touch the source, to maybe catch the disease themselves. He let the man suck him clean, the humiliating, eager slobber of it feeding his power. As the man worked, Brian felt a fresh, almost painful surge in his own muscles. His shoulders itched, then burned, as they expanded another fraction of an inch. The feed was working in reverse, too. Their desire was fueling him.
Marcus roared, his orgasm shaking his entire frame as he emptied into the spotter. He pulled out, turned, and his eyes found Brian’s. They were feral, unrecognizable. Sweat and spit glistened on his chest. “Again,” Marcus panted, not a question but a law of physics. His cock, thick and veined and angry-red, was already rising once more, a hideous biological impossibility.
And they did. Again.
Brian took the bearded man over a weight rack, the cold steel of the bar pressing into the man’s stomach as Brian hammered into him from behind. The man chanted “yes, yes, yes,” into the mirror, watching his own reflection contort with each thrust. Marcus pulled the salt-and-pepper-haired man onto his lap on a flat bench, impaling him, his massive hands crushing the man’s thighs as he bounced him up and down like a toy.
They switched partners. They took two at once. Brian fucked a man’s mouth while Marcus took him from behind, their bodies sandwiching the whimpering figure between them. The air grew thick, humid, reeking of sex and a strange, coppery scent that was their own accelerated metabolisms. Cum pooled on the rubber flooring, streaked across bench pads, dripped from chins and assholes.
And they grew. Not in subtle fractions now, but in visible, disquieting leaps. Brian felt his spine crackle as he gained another half-inch in height. Marcus’s deltoids swelled, rounding into terrifying cannonballs. Their skin stretched taut, glowing with a sick, healthful sheen. The mirrors around them reflected not a scene of depravity, but of transformation. Of gods being forged on an anvil of flesh.
Brian lost count of the bodies, the mouths, the holes. It was a circuit, a feedback loop of need and satiation that only amplified the need. He came a fourth time, a fifth, shooting ropes of thick, pearlescent fluid across a man’s back that seemed to sizzle on the overheated skin. There was no refractory period, only a continuous, driving imperative. The gym was their colony now, and they were the ravenous, insatiable kings.
Eventually, there was a lull. Men lay strewn across equipment and floor, spent, glazed, some weeping softly. Brian and Marcus stood in the center of the ruin, chests heaving, their bodies slick and monstrous, larger than they had been even twenty minutes prior. The silent, flickering fluorescent lights hummed above them.
The front door of the gym rattled. Then the jingle of keys. The scrape of a lock.
A man’s voice, annoyed, tired, called out. “Hello? We’re closed, folks. Security says the lights are still on. You gotta clear out.”
It was the night manager, finally making his rounds.
Brian and Marcus turned their heads in unison, their necks emitting soft pops. They looked at the door, then at each other. The hunger hadn’t subsided. It had simply found no more fuel in this drained room.
Fresh fuel was about to walk in.
The metallic jingle stopped. The gym's main door swung inward, carving a wedge of yellow parking lot light through the steam and gloom.
Frank, the night manager, stood silhouetted in the doorway. He was a thin man in a polo shirt, a ring of keys dangling from his finger. "Alright, folks, you gotta—" His sentence died. His eyes, adjusting from the dark lot to the fluorescence, took in the sce
"Alright, folks, you gotta—" His sentence died. His eyes, adjusting from the dark lot to the fluorescence, took in the scene.
It wasn’t the discarded men, slack and glistening on the floor, that froze him. It was the two figures standing in the center. They were too big. Their proportions broke some fundamental rule of the human form. The air itself smelled wrong—like ozone, sex, and burning copper.
Frank’s keys hit the rubber mat with a dull jingle. His mouth worked, but only a dry click came out.
Brian moved first. Not with the speed of a man, but with the eerie, fluid smoothness of a predator that knows it cannot be outrun. He was in front of Frank before the manager could blink, his new bulk blocking the door, blocking the world outside.
“Late night?” Brian asked. His voice was a rockslide.
Frank stumbled back a step, his shoulder hitting the doorjamb. “What… what is this? What did you do to these people?” His gaze darted to a man weeping softly by the leg press.
Marcus stepped up beside Brian, a wall of muscle. “We showed them,” he said, his tone almost conversational. “They wanted to see. They asked.” He placed a massive hand on Frank’s shoulder. The pressure was absolute, a vice of flesh. “You see?”
Frank tried to shrink away, but there was nowhere to go. His eyes were wide, white-rimmed with terror. But beneath the terror, as he looked up at the impossible breadth of Marcus’s chest, at the detailed map of veins on Brian’s arms, something else flickered. A dreadful, fascinated hunger. He’d worked in a gym for fifteen years. He knew what a natural physique looked like. This was something else. This was magic.
“I see,” Frank whispered, the lie thin.
“No,” Brian said, leaning close. Frank could feel the heat radiating from him. “You don’t. Not yet.”
Frank was propelled forward, Marcus’s hand guiding him like he was a child. They walked him past the ruin of spent bodies, towards the free weight area. The silence was broken only by the hum of the lights and the soft, wet sound of Frank’s sneakers on the sullied floor. He trembled, his mind screaming to run, but his legs wouldn’t obey. The scent here was overwhelming—semen, sweat, and that sharp, metallic pheromone that seeped from Brian and Marcus’s pores. It dug into his brain, short-circuiting panic, replacing it with a low, thrumming curiosity.
“On your knees,” Marcus said, not unkindly. It was a simple instruction.
Frank sank down. The cold rubber bit through his thin khakis. He stared at the fly of Brian’s shorts, at the profound swell there, darkened with sweat and other things. His professional revulsion warred with a deep, shameful pull.
Brian hooked his thumbs into his waistband. “Open your mouth.”
Frank’s lips parted. A shaky breath escaped him. He didn’t want to. He did.
Brian’s cock, thick and heavy, slid past his lips. It was warm, alive with a persistent thrum. It tasted of salt and something bitter, chemical. Frank gagged instinctively, his throat convulsing.
“Suck,” Brian commanded, his fingers tangling in Frank’s thinning hair. “Suck like you mean it. Like you want what’s in it.”
Frank’s eyes watered. He obeyed. His tongue flattened, lapping at the shaft. He took it deeper, fighting his own reflexes. The taste was wrong, but the act felt weirdly right. It was submission to a force greater than himself. A reprieve from thinking. From being Frank the night manager. He was just a mouth now. A service.
He heard a zipper. Marcus stepped around, his own cock, a brutal, veined thing, presented itself at Frank’s eye level. “Don’t forget this one,” Marcus said, tapping Frank’s cheek with it.
Frank switched his attention, taking Marcus into his mouth with a desperation that surprised him. He bobbed between them, a human prayer bead. Their hands were on his head, not guiding, but possessing. They used his face, his throat. He choked and slurped, tears cutting clean lines through the grime on his cheeks. He was humiliated. He was hard in his own pants.
“Stand up,” Brian grunted, pulling himself free with a wet pop.
Frank stumbled to his feet, dizzy. Marcus spun him around, bending him over the cool, slick surface of the preacher curl bench. His cheek pressed against the vinyl. He felt his pants and underwear being yanked down to his ankles. The air was cold on his exposed skin.
“Please,” Frank whimpered, the word muffled.
“Please what?” Marcus asked, spreading Frank’s cheeks. His thumb, slick with Frank’s own spit, rubbed against his hole. “You walked in. You looked. You wanted this.”
“I didn’t—”
The denial was crushed by a scream as Brian pushed into him. There was no preparation, no care. It was a single, merciless impalement. Frank felt torn open, a white-hot spear of pain splitting him in two. He scrabbled at the bench, his nails scraping the padding.
Brian fucked him with a slow, devastating rhythm. Each thrust jarred Frank’s teeth against the vinyl. The pain began to blur, mutating into a fullness so profound it bordered on nausea. He felt stuffed, owned. He could feel every ridge, every pulse of the thick shaft inside him.
Then Marcus was in front of him, forcing his head up. “Look at me,” Marcus growled. Frank focused through the tears. Marcus’s face was changing. The jaw was thickening, the brow ridge pushing forward. A crackling sound emanated from his shoulders. “Watch what you’re getting.”
Marcus shoved his cock into Frank’s open, gasping mouth. Frank gagged, his throat assaulted from both ends. He was a fleshy conduit between them. Brian’s punishing drives from behind slammed him forward onto Marcus’s length, over and over. The rhythm was brutal, mechanical. In, out. Choke, gasp. The world narrowed to the slam of flesh and the raw, animal sounds he was making.
Something shifted inside Frank. Not just the violation, but a deeper, cellular stirring. A strange warmth blossomed in his gut, spreading outward. It was the heat from their bodies, he thought dimly. Their sweat was dripping onto his back, mixing with his own. But it was more than heat. It was an infusion.
He felt a sharp twinge in his shoulders. A burning along his spine. The pain of being fucked was still there, but it was being drowned out by this new, interior fire. He tried to cry out around Marcus’s girth, but the sound was a muffled gurgle.
Brian’s thrusts became erratic, faster. “Fuck, he’s tight,” Brian groaned, his voice strained. “He’s getting tighter.”
He was. Frank could feel his own body clenching, changing. The muscles in his back were knotting, thickening. The pain in his shoulders wasn’t from strain; it was from growth. His scapulae grated under the skin, shifting outward. A strangled moan vibrated in his throat.
Marcus pulled out of his mouth, watching with predatory fascination. “Look at his back,” he said, his voice filled with awe.
Brian slowed his thrusts, leaning to look. Frank’s previously narrow, soft back was rippling. Deltoids swelled from his shoulders like mushrooms after rain. The trapezius muscles thickened, rising from his neck. It wasn’t the controlled, artistic growth they had experienced. It was violent, lopsided. One latissimus dorsi flared wider than the other, stretching the skin taut and shiny.
“He’s transforming,” Brian breathed, still moving inside him with a shallow, grinding motion.
“They transform him,” Marcus corrected, a dark smile in his voice. He placed his hands on Frank’s newly burgeoning shoulders, feeling the muscle writhe and expand under his palms. “Our little fountain. It’s in our cum. It’s in our sweat. It’s in the fucking air we breathe now.”
The realization hit Frank through the haze of pain and surreal pleasure. This was the price. This was the gift. He was being remade in their image, but crudely, desperately. His body was a frantic sketch where theirs were finished works.
Brian’s rhythm broke. He drove deep, holding Frank against the bench as he came. Frank felt the hot, internal flood, and it was like a spark to gasoline. The fire in his veins exploded.
His spine cracked audibly. His shoulders broadened another inch, tearing the seams of his polo shirt. A choked roar erupted from him, distorted by his changing vocal cords. His biceps swelled, straining against his sleeves. The change was accelerating, feeding on the raw material of Brian’s release.
As Brian pulled out, Frank collapsed onto the bench, his body shuddering with uncontrolled contractions. He was wider. Thicker. His once-slack arms now showed the hard curve of new muscle. But the transformation was grotesque, unfinished. One arm was visibly larger than the other. His pecs were swollen mounds lacking definition.
He panted, staring at his own hands. They were stranger’s hands, blockier, the knuckles pronounced.
Marcus crouched beside him, cupping Frank’s misshapen pec. “Not bad for a start,” he mused, squeezing the firming flesh. “You’ll need more. Lots more. To even it out.”
Frank looked up at him, his eyes wide with horror and a terrifying, dawning need. The hunger was there now, a hollow, screaming void inside his newly expanded ribcage. He didn’t want it. He craved it.
From across the room, a phone buzzed on the floor, skittering in a puddle. Then another. A video was being shared. A new video. Filmed from the floor by a broken man with a trembling hand. It captured the manager on his knees, the change beginning in real time.
Brian turned, sensing the digital pulse echoing their own. He looked at the scattered, drained men starting to stir, to look at Frank with not pity, but a hungry, jealous recognition. He looked at the door, still ajar, leading to the empty parking lot, the sleeping town, the unsuspecting world.
The infection had a new carrier. And the night was still young.
