The clang of iron echoed through Titan’s Forge, a powerlifting gym where stained rubber mats bore the sweat of decades and the air thrummed with the bass of dropped deadlifts. Here, amid the scent of chalk and ammonia of old sweat, two men worked out together.
Ethan Hale, 28, stood at the squat rack, his compact frame a study in density. His torso, a barrel of muscle sheathed in coarse chest hair, tapered into quads that strained against faded compression shorts. Thick trap muscles bridged his neck to shoulders rounded from years of bench presses, their delts like stone beneath a patina of sweat. A brown beard framed a jaw clenched around exertion, his every exhalation a growl as he hoisted 250 kg—a weight that bent the bar but not his resolve.
Across the platform, Leo Voss, 22, paced like a caged predator, his lithe 6’1 frame taut with restless energy. His body was a scaffold of untapped potential: shoulder blades flaring beneath paper-thin tank tops, the serratus anterior muscles at the sides of his chest rippling with each breath like gill slits. Though his arms lacked Ethan’s vascularity, his lats flared in a V that disappeared into lifting belts worn like a second skin. Youth rendered him hairless save for a light blond fur at his navel, a contrast to Ethan’s primal caveman-like form.
“Spot me,” Leo demanded, voice cracking as he loaded the bench press. Ethan grunted, wiping chalk from his palms onto thighs that could crack walnuts. Their eyes met—hazel burning into cobalt—as Ethan loomed over the bar.
“Arch higher,” Ethan rumbled, calloused thumb brushing Leo’s ribcage. “You’re benching like a virgin.”
Leo’s retort died as 140 kg descended. His pecs flattened into trembling slabs, nipples pebbling against cold steel. Ethan’s hands hovered, close enough for Leo to feel the furnace heat of his palms.
“Drive through your heels,” Ethan growled, “or you’ll fold.”
The younger man’s face contorted, triceps shaking as he pressed upward—a slow, grinding ascent that made his abs stand in brutal relief. When the rack clanged, Leo lay panting, sweat pooling in the hollow of his clavicles. Ethan’s laugh was a deep tremor.
“Pathetic.”
“Says the guy who squats like a pregnant crane,” Leo shot back, rolling upright to reveal Adonis belts cutting into his narrow waist.
Their banter crackled like live current. Ethan admired the younger man’s audacity—the way his hips jutted above thick glutes that begged to be gripped. Leo feigned indifference even as his gaze lingered on the older man’s muscular back, muscles rippling like pythons as Ethan reloaded the bar.
Post-workout, they collapsed on leather benches, the vinyl squeaking beneath their sweaty butts. Ethan’s chest heaved, sweat staining his shirt where it lay on the valleys between his abs. Leo pretended to check his phone, stealing glances at the older man’s dick outlined through damp shorts—a thick bulge that stirred something primal in his gut.
“New tattoo?” Leo nodded to the serpent inked around Ethan’s bicep.
“Year ago.” Ethan flexed unconsciously, the creature writhing across his brachialis. “You?”
Leo raised his arm, revealing a sparrow near his axilla. “Mom’s favourite bird.”
Ethan’s finger grazed the ink. “Should’ve been a peacock. Would suit you beter.”
Leo’s heart hammered inside his chest at Ethan’s casual touch. Across the gym, unnoticed, a corroded barbell plate, etched with strange symbols that looked like erect dicks, began to glow.
The next day, and the two men were back at the gym again, like they were every day.
Leo’s hands closed around the knurled steel of the deadlift bar, the same corroded plate from yesterday’s session glaring up at him like a menacing eye. 300 kg: a weight neither man had dared attempt. Ethan leaned against the chalk-stained wall, arms crossed, watching the younger man’s pre-lift ritual: the deliberate roll of shoulders, the three sharp breaths, the way Leo’s glutes dipped as he hinged at the hips.
“You’ll snap like a twig,” Ethan taunted, though his throat tightened as Leo’s glutes flexed beneath thin polyester shorts.
Leo said nothing. His trap muscles tensed like drawn cables as he gripped the bar, callouses catching on the rough steel. The first pull began as physics dictated—quads firing, lumbar spine locked, scapulae retracted. Then the world shifted.
A low hum emanated from the magical plate. Leo’s breath hitched as heat flooded his spine, spreading like molten lead through his nervous system. His back muscles twitched, then began to swell—ropey muscles thickening into columns that pressed against his skin like living things. The hem of his tank top ripped at the seams as his lat muscles erupted outward, fanning into wings that cast shadows across the platform.
“What the fuck!” Ethan surged forward, but the air itself seemed to thicken, pressing him back.
Leo’s scream morphed into a roar as his femurs cracked—lengthening, reshaping. His quads ballooned, veins surfacing like tributaries across terrain that rippled and expanded. The gym’s fluorescent lights glinted on sudden sweat as his delts rounded into boulders, triceps splitting into twin peaks that strained against dissolving sleeves.
“Don’t come near me!” Leo’s voice dropped an octave mid-cry, his Adam’s apple bobbing above a sternocleidomastoid now thick as a boa constrictor.
The young man’s shorts surrendered first. A thunderous rip echoed as his glutes surged outward, cheeks hardening into marble slabs that flexed with every micro-adjustment of his stance. His burgeoning cock strained against the last shreds of fabric, the frenulum visibly pulsing as pre-cum darkened the cloth with wetness.
Ethan’s mouth went dry as he watched Leo’s transformation. Leo’s once narrow waist now flared into a V so extreme it defied anatomy, his obliques cascading like topographic lines toward his pelvis and his rapidly swelling muscular butt. The younger man’s pecs bounced with each ragged breath—thickened, hairless, nipples ruddy and erect as they stretched taut over swelling muscular pecs that inflated with every breath.
Leo gasped as Ethan continued transforming. Ethan’s trap muscles now grew into thick triangles over his shoulders, giving him a bull-necked silhouette.
Tendons played symphonies beneath Leo’s skin. His muscles rippled, each of his rib expansion audible as cracks that should’ve been screams. His arms—now thicker than Ethan’s thighs—shook not from weakness but from raw power seeking an outlet to test their strength.
The final tear came as Leo finally dropped the barbell. What remained of his shirt fell away, revealing a torso that could’ve been chiselled by a sculptor. His abs stood in eight brutal segments, skin stretched so tight over the ab muscles that every vascular muscle fibre was visible. Sweat cascaded down his back into the cleft of buttocks that clenched with enough force to dent steel.
As the bar clanged down, Leo turned—slowly, as if moving through jelly—and Ethan’s knees nearly buckled. The younger man’s dick, now fully exposed and thick as a forearm, curved upward against a dusting of golden pubic hair. His scent—musky, manly, primordial—flooded Ethan’s nostrils with pheromones.
“Well?” Leo’s new deep voice shook dust from the rafters. He flexed a bicep that split into twin peaks, a thick vein throbbing over the peaks. “Still think I’ll snap with that lift?”
Ethan’s response died in his throat. His own shorts grew uncomfortably tight as he catalogued the changes: the way Leo’s traps sloped into delts that could shelter small animals, the diamond-shaped window between pecs where chest bone met solar plexus, the sheer mass of him that made the 300kg lift look light.
Unthinking, Ethan reached out. Calloused palm met Leo’s pecs—warm, granite-firm, yet quivering with residual metabolic fire.
The air crackled with testosterone. Leo’s new form dominated the platform, his shadow swallowing Ethan whole. Before the older man could retreat, Leo’s hand—now broad enough to palm a basketball—closed around his bicep.
“Scared, old man?” Leo’s voice rumbled through Ethan’s sternum.
Ethan wrenched free, pride flaring. “Of you? You’re still the twerp who—hngh!”
Leo moved with preternatural speed, seizing Ethan’s waistband. The fabric tore like rice paper, exposing the older man’s hairy thighs. A growl built in Leo’s throat as he lifted Ethan one-handed, veins in his forearm branching like lightning across muscle the size of a haunch.
“Put me down, you fucking—!” Ethan’s fists pounded Leo’s pecs, each strike sending shockwaves through knuckles. The younger man’s nipples—now the size of silver dollars and stiff—grazed Ethan’s chest through tattered fabric.
“Make me.”
The challenge hung between them. Ethan twisted, driving a knee into Leo’s abs. The impact should have folded him. Instead, Leo’s eight-pack flexed—a living wall of striated muscle—and rebounded Ethan’s leg.
“Fuck!” Ethan gasped, pain and awe mingling as he stared at the dent his knee left in Leo’s flesh. The depression filled slowly, like memory foam shaped by gods.
Leo grinned, canines glinting. He dropped Ethan, then flexed—a full-body contraction that made his lat muscles unfurl like bat wings. Sweat launched from his traps in an arc, pattering against Ethan’s face.
“Touch me,” Leo commanded, spreading arms that could strangle an oak.
Ethan’s throat worked. His fingers trembled as they neared Leo’s solar plexus—now a shallow crater between mountainous pecs. The first contact stole his breath: skin hotter than sauna stones, vibrating with the aftermath of his transformation.
“Harder,” Leo hissed.
Ethan pressed. His fingertips sank into the younger man’s pecs, the muscle dense and heavy as lead, yet yielding like dough. Leo’s nipple hardened against his palm, a pebble in a river of flesh.
“Up,” Leo ordered.
Hands skated over delts that sloped like mountain ranges. Ethan’s thumbs found the cleft between Leo’s front and side delts, probing their deep valley of separation.
“Fuck,” Ethan breathed as the muscle twitched under his touch, rolling like storm clouds.
Before Ethan could react, the younger man gripped his own cock—thick as a beer can, glans purpling—and slapped it against Ethan’s abdomen. The thwack echoed. Pre-ejaculate smeared across his chest hair.
“Look what you did,” Leo purred, guiding Ethan’s hand to his engorged member. The older man’s fingers couldn’t meet around the shaft.
“I didn’t—”
“Look.”
Ethan’s scientific mind warred with primal hunger. His thumb brushed the ridge if Leo’s cock head, feeling the frenulum pulse like a trapped heartbeat. Leo’s testicles—heavy as billiard balls, crisscrossed with veins—drew up tight against a perineum that flexed like hydraulic machinery.
“Still think I’m a twerp?” Leo grabbed Ethan’s nape, forcing him nose-first into his armpit. The older man inhaled musk—salt, iron, and something electric—as his cheek pressed against Leo’s teres major.
“Fuck you,” Ethan snarled into damp flesh.
“Try.”
They crashed onto the platform, Leo’s mass denting rubber mats. Ethan straddled his waist—a laughable pretense of control—as his knees sank into Leo’s external obliques. The younger man’s hands roamed Ethan’s back, blunt nails raking old stretch marks.
“Pathetic,” Leo mocked, arching to grind his erection against Ethan’s perineum. “You’re softer than my warm-up sets.”
Ethan retaliated with a chokehold—forearm crushing the younger man’s trachea. Leo’s neck muscles bulged, his hyoid bone pressing against Ethan’s skin like a knuckle.
“Yield,” Ethan demanded.
Leo’s response was to flex his sternocleidomastoids. Ethan’s arm popped free, bicep quivering from the strain.
“My turn.”
In one fluid motion, Leo flipped them. Ethan’s skull thudded against matting as the younger man pinned his wrists above his head—thumb and index finger circling both forearms with room to spare. Leo’s quads settled on either side of Ethan’s hips, their vastus medialis heads trembling with restrained force.
“Feel that?” Leo ground his pelvis down, their erections separated by a thread of fabric. “That’s your doing. You did this by touching me.”
Ethan bucked, his lumbar spine bowing uselessly against Leo’s tailbone—a plinth of bone and muscle. The younger man’s glutes clenched, suffocating Ethan’s thighs in heat.
“I’ll kill you,” Ethan rasped, even as his hips stuttered upward.
Leo leaned close, pecs smothering Ethan’s face. “You made me hard,” he breathed, rolling nipples across his stubble. “Now taste it.”
The older man’s resolve shattered. His tongue darted out—once, twice—laving salt from areolae stretched taut over swelling glands. Leo threw his head back, tendons in his neck standing in high relief as Ethan bit down.
“Yes!” The shout shook dust from ceiling fans.
Ethan’s hands scrabbled for a hold, finding Leo’s back muscles. They contracted under his palms, thick as hawsers on a dreadnought. His nails dug trenches in sweat-slick flesh as Leo reared up, kneeling now to showcase his crowning glory—a penis throbbing with each heartbeat, foreskin retracted to reveal a glans shiny with exertion.
“On your knees,” Leo commanded.
“Go to hell.”
The slap came faster than sight—Leo’s palm imprinting Ethan’s pecs. Not pain, but shock radiated through muscle and bone. The older man found himself kneeling, face level with Leo’s groin.
“Lick.”
Ethan’s tongue darted out, tracing the dorsal vein. Iron and brine exploded across his taste buds. Above him, Leo’s hands fisted in his hair—not guiding, but anchoring as the older man took the engorged member past his lips.
“Deeper,” Leo growled, hips snapping forward.
Ethan gagged, tears blurring his vision of Leo’s flexed abs—a living washboard that rippled with every thrust. His nose pressed into golden pubic hair, coarse and damp with musk. The younger man’s grip tightened, forcing his head down as Ethan’s jaw stretched beyond comfort.
“You wanted this,” Leo panted, watching himself disappear down the older man’s throat. “Admit it.”
Ethan couldn’t speak—couldn’t breathe—but his own erection, trapped in torn shorts, answered for him. Leo laughed, the vibration traveling through his shaft into Ethan’s skull.
The younger man pulled Ethan’s head free with a wet pop. then he said, “again.”
Ethan’s surrender was total. His lips stretched around Leo’s girth, saliva pooling at the corners of his mouth as the younger man’s glans breached his throat. Leo’s huge hands cradled Ethan’s skull, not forcing but claiming, thumbs tracing the older man’s jaw muscles at the side of his head as they flexed with each gag reflex.
“Good,” Leo rumbled, voice fracturing into gravel. “Good.”
The praise ignited something feral in Ethan. His tongue mapped the frenulum’s ridge, lapping at precum that tasted of burnt copper. Leo’s pubic bone ground against his nose, the coarse hair there matted with sweat that carried the tang of overclocked adrenal glands. Above him, the younger man’s abs rippled like a stoked forge, each contraction of his abs squeezing fresh droplets of sweat from pores that gleamed under fluorescent lights.
Leo’s hips began a piston rhythm, each shallow thrust measured to deny Ethan air. The older man’s vision swam, tears carving paths through stubble as his nostrils flared against Leo’s musk-drenched groin. When he finally pulled back, dragging his shaft across Ethan’s bruised lips, a silver strand of saliva connected them like a marionette string.
“On your back,” Leo ordered, nudging Ethan’s clavicle with a foot that could crush cinderblocks.
The older man complied, spine pressing into sweat-cooled rubber. Leo loomed over him, backlit by buzzing lights, his silhouette a cathedral of muscle. Ethan’s gaze traced the younger man’s hips down to thighs that dwarfed his own.
“Still want to stop?” Leo taunted, kneeling to straddle Ethan’s chest. His ballsack brushed the older man’s chin, testicles drawn tight and sheened with sweat.
Ethan’s retort died as Leo’s hands closed around his throat—not choking, but demonstrating. The younger man’s forearm tendons stood in high relief, each twitch telegraphing power that could break Ethan’s back. Yet his grip remained featherlight, a paradox that made Ethan’s pulse beat fast.
“Watch,” Leo commanded, releasing Ethan to grip his own penis.
The older man’s breath hitched as Leo began to stroke—slow, deliberate pulls that made his foreskin glide over the engorged glans. Veins writhed beneath the surface like buried cables, the cock shaft swelling until the cock head turned purple. Precum welled at the slit, viscous and milky white, dripping onto Ethan’s chest.
“Lick it.”
Ethan’s tongue darted out, collecting the offering. The flavour detonated on his palate—salt, manly musk, something unnaturally masculine and pungent—as Leo’s free hand tangled in his hair.
“All of it.”
The younger man leaned forward, balancing on one arm as his lat muscles blotted out the ceiling. His cock hovered over Ethan’s face, pre-cum splattering onto his eyelids and lips. Ethan’s tongue became a scavenger, lapping at the droplets beading on his own skin, each taste sparking synaptic wildfires.
“You love this,” Leo growled, watching Ethan’s adam’s apple bob. “Love being beneath me.”
A denial formed and died in his mouth, as Leo’s thumb brushed Ethan’s lower lip, then used it to force Ethan’s jaw wider.
“I’m going in.”
Leo put the tip of his large cock head into Ethan’s mouth. Ethan’s molars ground against Leo’s cock head in his last shred of defiance, but the younger man’s cock was tougher than rawhide. Ethan was struggling to breathe, as saliva and pre-cum leaked from the corners of his mouth. Leo’s other hand never ceased stroking his exposed shaft hanging outside Ethan’s mouth, his rhythm now erratic, hips stuttering as he loomed closer to climax.
“Want to feel my balls?” Leo rasped, dragging Ethan’s hand to his ballsack.
The older man’s fingers sank into the hot flesh of Leo’s man meat. Leo’s testicles rolled under his touch, each the size of a plum and twice as dense, their epididymal sacs of sperm coiled like springs. Ethan squeezed—once, twice—and Leo’s roar shook the platform as his cockhead popped out of Ethan’s mouth.
“Now!”
The first spurt caught Ethan across the cheekbone, thick as egg white and hotter than fever. Leo’s back arched obscenely, back muscles standing in relief like fossilized waves as he painted the older man’s torso in stripes. Ethan’s own neglected erection throbbed in time with each pulse, his abdominal hair matting under the onslaught.
“Fuck!” Leo’s voice broke mid-syllable, his quads quaking as the final contractions emptied him.
Silence fell, broken only by their ragged breathing. Leo collapsed forward, his pecs smothering Ethan’s face, nipples chafing against stubble. The older man’s hands rose of their own accord, mapping the valleys between Leo’s trap muscle fibers, kneading delts that still quivered with aftershocks.
“Am I still pathetic?” Leo panted, his bravado undercut by the vulnerability in his tone.
Ethan’s laugh emerged muffled against pec flesh. “You wish.”
The younger man rolled aside, his spent cock lying heavy on Ethan’s thigh. Their eyes met—hazel drowning in blue—as Ethan’s fingers traced the arch of the younger man’s groin, feeling the his blood’s frantic post-orgasmic rhythm.
“Your turn,” Leo murmured, hand drifting toward Ethan’s neglected erection.
Leo’s hand closed around Ethan’s erection with the finality of a padlock snapping shut. The older and smaller man arched off the mat, a guttural “Fuck!” tearing from his throat as callouses abraded his hypersensitive frenulum. Leo’s transformed body loomed over him, a monolith of sweat-slick muscle.
“Quiet,” Leo growled, his free hand pinning Ethan’s hipbone with enough force to bruise. “This is mine now.”
Ethan’s retort dissolved into a moan as Leo’s thumb circled his glans, smearing precum across the entire cock head, as he begin stroking Ethan’s cock with his thick strong fingers. The younger man’s other hand—still sticky with his own cum—fondled the older man’s hairy ball sack, blunt nails caressing through thick wiry pubic hair.
“Pathetic,” Leo mocked, though his breath hitched as Ethan’s testicles drew up tight. “All these years… and you’ve been starving for me.”
Ethan’s hands flew to Leo’s traps, fingers digging into muscle dense as quarry stone. “Do it or don’t, you overgrown—”
The threat died as Leo increased the strength of his grip on Ethan’s cock, doing a merciless corkscrew motion that made Ethan’s tailbone lift clear of the mat with each stroke. The younger man’s bicep flexed, veins surfacing like relief maps as he began to pump in earnest.
“Beg.”
“Fuck y—ah!” Ethan’s hips stuttered as Leo’s pace quickened, the younger man’s transformed reflexes anticipating every micro-twitch of his body.
Leo leaned close, pecs smothering Ethan’s face. “Say it.”
The older man’s teeth found Leo’s left nipple—clamped down hard. Leo’s roar shook dust from the rafters as he retaliated, his free hand gripping Ethan’s throat just shy of asphyxiation.
“Again,” Leo demanded, hips grinding his renewed erection against Ethan’s thigh.
Ethan obliged, tongue lapping on Leo’s areola. The younger man’s grip tightened, not on Ethan’s throat, but on his erection—a vise-like squeeze that blurred vision and reason.
“Louder.”
Ethan’s back arched like a drawn bow, heels scrabbling against mats gone slick with sweat and spend. Leo’s nose drank in the older man’s musk—darker, earthier than his own, tinged with cortisol and decades of suppressed desire.
“You want this,” Leo hissed, dragging his cock along Ethan’s butt. “Want to be mounted.”
“Take me—”
The affirmation became a scream as Leo breached him.
The younger man’s girth stretched Ethan’s sphincter beyond reason, burn transmuting into white-hot rapture. Leo’s hands anchored Ethan’s hips, thumbs denting his glutes as he sheathed himself to the hilt.
“Look,” Leo commanded, dragging Ethan upright against his chest.
The older man’s reflection stared back from the gym’s fogged mirrors—a wiry frame dwarfed by Leo’s mass, his own erection bobbing pathetically against the younger man’s armoured abs. Leo’s hands splayed across Ethan’s lean pecs, fingers toying with his thick chest hair as he began to move.
“Feel every inch,” Leo rumbled, his pubic bone grinding Ethan’s glutes with each thrust.
Ethan’s nails raked Leo’s quads in his ecstasy. The younger man’s thigh muscles quivered under the assault but never faltered in their piston rhythm.
“Harder,” Ethan snarled, teeth sinking into Leo’s traps as he hugged the giant young man tighter.
The transformed behemoth obliged. His thrusts became seismic, each impact reverberating through Ethan’s prostate like a mallet strike. The older man’s neglected erection bounced against his abdomen, pre-cum painting streaks across Leo’s abs
“Close?” Leo taunted, with a mocking grin.
“Go to h—nngh!”
The younger man’s free hand found Ethan’s balls, thumb pressing mercilessly against the bulging tissue. Ethan’s vision whited out in both pleasure and pain as his climax detonated—a silent, full-body convulsion that painted Leo’s lower abs in ropes of spend.
“Watch,” Leo growled, slowing his thrusts to excruciating precision.
Ethan’s head lolled against the younger man’s chest, eyes struggling to focus as Leo’s cock withdrew almost completely, then surged back in, gripping Ethan’s ball sack as a handle. The mirror showed everything—the obscene stretch of his body, Leo’s glutes flexing like tectonic plates, their combined sweat pooling dripping from Ethan’s lean muscles.
“Mine,” Leo grunted, pace becoming erratic.
Ethan’s spent body jerked like a marionette as the younger man’s climax hit—hot floods of semen that seemed endless, each spurt wringing a guttural cry from Leo’s throat.
They collapsed sideways, Leo’s bulk cushioning Ethan’s fall. The younger man’s arms—still quivering with residual tension—caged the older man against his chest. Ethan’s ear pressed to Leo’s pecs, hearing the thunderous heartbeat within.
“Still… talking shit?” Leo panted, fingers idly tracing Ethan’s hip flexors.
The older man’s response was to uselessly thump Leo’s massive pecs with his fist. The younger man’s laugh shook them both, a deep tremor that echoed through flesh and bone.
Outside their bubble of sweat and spent lust, the cursed barbell plate glowed brighter. As though hypnotised, Ethan suddenly disentangled himself and walked towards the deadlift bar in a trance.
The cursed barbell plate pulsed like a dying star as Ethan gripped the deadlift bar, his knuckles bleaching white against knurled steel. Leo crouched nearby, sweat-smeared hands braced on knees that still trembled from their earlier collision. The air vibrated with ozone and unspent desire.
“Be careful,” Leo warned.
Ethan ignored him. 350 kg—a weight that would’ve crippled his former self. The first pull began as defiance, ended as revelation.
Heat erupted from Ethan’s tailbone, molten and voracious, as the runes flared. His back muscles snapped audibly, muscle fibres splitting and reforming into cables thick as suspension bridges. Leo’s breath hitched as the older man’s shirt shredded, revealing a lumbar spine that rippled like a serpent beneath suddenly thickening skin.
Ethan’s trap muscles surged upward, swallowing his neck in a single grotesque flex. His beard darkened to obsidian, coarser hairs sprouting across shoulders that broadened like tectonic plates shifting. The older man’s once-rounded delts sharpened into angular peaks, posterior fibres tearing through fabric as they ballooned.
“Fuck… fuck,” Leo whispered, torn between terror and arousal as Ethan’s lats unfurled and became even bigger than Leo was. What had been wings became sails, stretching the older man’s torso into a V so extreme it warped perspective.
Ethan’s femur bones cracked—lengthening, densifying—as his quads exploded outward. The gym’s fluorescent light caught new striations in his thigh muscles, each muscle fibre splitting into into more muscle fibres that flexed independently. His shorts vaporized, exposing a penis that thickened to obscene proportions, veins writhing beneath skin stretched drum-tight.
Leo’s throat dried as he watched Ethan’s scrotum swell, testicles descending with a weight that defied gravity, the sac’s wrinkled texture smoothing into taut leather. Precum dripped freely from the older man’s glans, each droplet hitting the mat with a hiss that steamed.
“Look at you,” Ethan rumbled, his new deepened shaking loose ceiling tiles. The voice was his, yet more.
Leo staggered back as Ethan completed the lift, the bar bending around fists that now resembled sledgehammers. The older man’s pecs bounced with the lockout—living stone-like muscles striated with new vascular pathways. His abs split into ten defined segments, skin stretched so thin over each ridge that his skin glistened.
The transformation reached a crescendo. Ethan’s jawline squared, jaw bone reforging as his neck thickened to match Leo’s transformed girth—then surpassed it. Coarse black hair cascaded down his back, merging with a sudden pelt that carpeted his butt and flanks. His nipples—now jet-black and twice as big as dollar coins—puckered above pecs that could shelter a normal man.
“This,” Ethan boomed, flexing biceps that split into three distinct peaks, “is what you woke.”
Leo’s arousal warred with primal terror. The older man’s dick now rivalled his forearm in girth, the glans flaring like a mushroom cap, foreskin retracted to reveal a urethral slit dripping continuous rivulets. His scent—burnt amber and forged iron—overpowered the gym’s chlorine stench.
“Touch me,” Ethan commanded, seizing Leo’s wrist.
The younger man’s hand looked childish against Ethan’s transformed forearm, fingers barely spanning half the circumference. Ethan guided him across boiling delts, down trap muscle fibres that twitched like live wires.
“Here,” the titan growled, slamming Leo’s palm against his left pec.
Leo’s fingers sank into muscle denser than steel. Ethan’s heartbeat thundered through the younger man’s arm, each heartbeat vibrating up to his molars.
“Pathetic,” Ethan sneered, watching Leo’s erection straining. “You thought you were peak?”
The older man flexed his lats, the sheer expansion of tissue thumping Leo backward. Ethan’s transformed dick bobbed with the motion, glans grazing the younger man’s thigh and leaving a searing welt.
“You… you’re monstrous,” Leo breathed, torn between revulsion and hunger.
Ethan’s laugh shook the walls. He gripped his own erection, veins bulging like ivy on a skyscraper as he gave a single stroke. Precum arced through the air, splattering Leo’s collarbones.
“Kneel.”
Leo’s body obeyed before his mind protested. The younger man’s nose pressed into Ethan’s transformed pubic hair—coarse as steel wool, reeking of dominance. Above him, the older man’s ball-sack hung like a pendulum of raw power, each testicle visibly churning with cum and testosterone.
“Lick,” Ethan ordered, thumb denting Leo’s chest.
The first tentative swipe of tongue across Ethan’s cock head ignited chaos. Leo’s vision swam as Ethan’s musk flooded his sinuses—a pheromonal cocktail that bypassed cognition and stabbed directly into the hindbrain. His lips closed around the titan’s glans, jaw nearly dislocating to accommodate the girth.
“Harder,” Ethan growled, hips snapping forward.
Leo gagged, tears blurring his view of Ethan’s quads—each quad muscle now larger than his own head. The older man’s hands clamped his skull, not guiding but testing, probing the limits of Leo’s transformed durability.
Ethan’s thumbs dented Leo’s jaw muscles, forcing the younger man’s jaw wider around his titanic girth. Saliva pooled and overflowed, dripping onto the older man’s ball-sack—now a pendulous mass of leather-tough skin veined like Damascus steel. Leo’s trachea fluttered against the underside of Ethan’s shaft, each choked breath vibrating through the older man’s cock.
“Pathetic,” Ethan growled, hips pistoning forward. Leo’s nasal bones creaked under the pressure, his transformed tear ducts leaking involuntary rivulets. “You thought you could handle this?”
The rhetorical question hung in the ozone-charged air as Ethan withdrew completely, leaving Leo gasping. The older man’s hands—now large enough to palm Leo’s skull—closed around the younger man’s trap muscles.
“Stand.”
Leo rose on quaking legs, his own formidable mass reduced to childlike proportions next to Ethan’s monolith frame. The older man’s lats cast a shadow that swallowed Leo whole, the edges tinged crimson by emergency lights.
“Test me,” Ethan commanded, spreading arms that could crush engine blocks.
Leo’s fist struck first—a right cross aimed at the older man’s solar plexus. The impact thudded like a wrecking ball hitting concrete. Ethan’s abs rippled, absorbing the blow, muscle fibres rearranging in visible waves.
“Harder,” Ethan sneered, fingers digging into Leo’s delts.
The younger man obliged, driving a knee into Ethan’s crotch. The powerful strike should have shattered the balls and hip bones of any mortal man. Instead, the older man’s pelvic muscles deep inside him muscle flexed, hardening to iron density, and his tough ball sack bounced against Leo’s knee unperturbed. Leo’s knee recoiled as if struck by a sledgehammer.
“Weak,” Ethan taunted, seizing Leo’s thigh. His fingers gripped Leo’s thich muscles squeezing until striations appeared between his knuckles. “Your turn.”
The older man’s open palm struck Leo’s pecs with the force of a battering ram. The younger man’s feet left the ground, his transformed mass crashing into the squat rack. Steel uprights bent around his silhouette, the sound of deforming metal mixed with Leo’s guttural groan.
“Up,” Ethan ordered, hauling Leo upright by his groin. The younger man’s erection—persistent despite the punishment—brushed against Ethan’s quads, leaving a glistening streak.
Ethan’s laugh shook dust from the ceiling. He pinned Leo against the ruined rack, their pelvises aligned. The older man’s dick—now a veined tower of flesh—rested heavy on Leo’s abdomen, its heat searing the younger man’s navel.
“Feel,” Ethan rumbled, rolling his hips.
The friction drew a ragged moan from both men. Leo’s hands scrabbled across Ethan’s sides, blunt nails finding purchase between rib-like muscle ridges. The older man’s pecs smothered Leo’s face, suffocating him in musk and metabolic heat.
“Beg to me break you,” Ethan demanded, teeth closing on Leo’s traps.
“Fuck...you,” Leo gasped, driving an elbow into Ethan’s abdomen.
The older man’s abdominal armour absorbed the strike, his abs contracting to trap Leo’s arm like a bear trap. Ethan leaned forward, using pure mass to bend the younger man over the wrecked rack.
“This is power,” Ethan hissed, lining his penis with Leo’s anal entrance.
The breach was tectonic. Leo’s transformed rectal muscles strained, then failed, as Ethan sheathed himself in a single thrust. The younger man’s scream atomized into breathless silence, his body arching against the older man’s chest.
“Move,” Leo choked, fingers clawing Ethan’s forearm.
The older man obliged with a snap of his hips that lifted Leo clear of the rack. Gravity ceased to matter—Ethan’s back muscles flexed in hydraulic rhythm, each thrust grinding the younger man’s prostate into paste. Leo’s neglected erection bounced against his own abdomen, pre-ejaculate spraying in arrhythmic arcs.
“Look,” Ethan commanded, seizing Leo’s jaw.
The mirror showed their obscene tableau: Ethan’s delts rippling like stormy seas, Leo’s body reduced to a plaything between the older man’s thighs. The younger man’s face—a mask of agony and ecstasy—pressed against Ethan’s pecs, lips brushing a nipple dark as volcanic glass.
“Mine,” Ethan growled, increasing tempo.
Leo’s body convulsed, his climax ripped from him by pure friction. Cum painted the older man’s lower abs in abstract streaks, each contraction of Leo’s bulbocavernosus muscle milked by Ethan’s relentless pace.
“More,” the titan demanded, hands migrating to Leo’s hips.
The final thrusts bordered on violence. Ethan’s glutes contracted with enough force to dent steel plates, the muscles deep inside his groin engorged to diamond hardness. When release came, it flooded Leo’s core with molten heat—a seemingly endless geyser that distended the younger man’s abdomen full of liquid sperm.
They collapsed forward, Ethan’s mass crushing Leo into the ruined rack. The older man’s breath roared like a blast furnace. Leo’s fingers traced the older man’s back in admiration.
“Still… cocky?” Leo rasped, cheek pressed to Ethan’s lats.
The older man responded by flexing all the muscles of his torso—a full-body spasm that lifted them both upright. Leo hung suspended, impaled and helpless, as Ethan carried him toward the glowing barbell plate.
The barbell plate detonated.
A shockwave of raw masculinity ripped through Titan’s Forge, reducing weight stacks to shrapnel and shattering mirrors into diamond dust. Ethan’s transformed frame absorbed the blast and its male energy, his body exploded even bigger, his trap muscles swelling to eclipse Leo’s head. The younger man hung impaled on the tip of the older titan’s cock, their combined mass cratering the platform beneath them.
“More,” Ethan commanded, not to Leo, but to the very laws of physics.
Their bodies became superhuman engines. Ethan’s quads—each thick rope of his quad muscles larger than a hose—flexed, launching them upward. The ceiling buckled, steel rafters bending around Ethan’s delts as he drove Leo into the roof. Fluorescent tubes burst in showers of glass, the sparks igniting airborne chalk into brief supernovae.
Ethan’s back muscles bowed, lifting his bulk momentarily as he bridged upward. Their pelvises ground together, the friction of cock against cock scorching the air with the stench of burning keratin.
“Show me what you can do,” Leo gasped, nails raking Ethan’s abdominal armour.
The challenge was met. Ethan’s hands—each finger thicker than a roll of quarters—closed around Leo’s hips. With a roar that shattered remaining windows, he wrenched the younger man upward, sheathing himself to the hilt in a single brutal thrust. Leo’s scream atomized into ultrasonic silence, his transformed rectum stretched beyond biological limits.
The gym became a furnace of hot male sex. Ethan’s piston-like thrusts cratered the floor, each impact spraying rebar and concrete dust. Leo’s retaliatory bites tore furrows in the older man’s traps, cum mixing with sweat to paint abstract murals across their heaving flesh.
“Look,” Ethan growled, rotating Leo’s neck toward the ruins of a mirror.
The reflection showed monsters—not men. Ethan’s cock had thickened into a veined monolith, its glans flared like a mushroom cloud, while Leo’s own erection dripped continuous streams of precum that sizzled on hot concrete. Their combined musculature defied physics: Ethan’s pecs sloped like mountains, Leo’s lats flared into fractal patterns of muscle fibres, and both men’s back stood taller than buildings.
“Finish it,” Leo demanded, clawing at Ethan’s sides
The older titan obliged. His thrusts became seismic, each shearing motion stripping concrete from foundation. Leo’s prostate swelled to the size of a coconut, his climax detonating in a silent scream that sprayed semen like a firehose across the ruined gym. Ethan’s release followed—a cataclysmic geyser that distended Leo’s abdomen visibly, hot floods of virility overflowing from his rectum to pool in the crater beneath them in a hot white pond of sperm.
The barbell plate’s final explosion tore reality.
The air itself thickened into an androgynous haze, every oxygen molecule imprinted with their pheromones.
When the collapse finished, only they remained—naked giants kneeling in a wasteland of their own creation.
“Again,” Leo rasped, erection already renewed.
Ethan grinned. “Always ready.”
