Chapter 3: Ben's fingers barely wrap around Alex's thickening girth as the vein-studded shaft pulses in his grip. 'Fuck... it's still growing,' he rasps, watching the ruler strain under the weight of Alex's engorged cockhead. Alex groans as Ben's own length swells against his thigh, both of them caught in a feedback loop of relentless, impossible expansion.
Ben stared at the ruler in his shaking hand, the cheap plastic bending slightly under the pressure of his newly thickened fingers. Twelve inches. Twelve fucking inches of thick, veined cock lay heavy against Alex’s equally monstrous thigh. The air crackled, thick with the smell of musk, sweat, and the metallic tang of something unnatural. Alex’s own colossal erection, resting obscenely against his stomach, pulsed visibly with each thunderous heartbeat that echoed in the cramped, overheated room.
"Jesus, Alex," Ben breathed, his voice a deep rumble like stones grinding together, the product of his enhanced vocal cords. His gaze traced the serpentine blue veins that snaked across the flushed, almost painfully swollen shaft. "Look at this fucking thing." He swallowed hard, the thick muscles of his neck bulging. "It’s… grotesque."
Alex flexed, still trying to process the sheer, terrifying mass of himself. His biceps, now dwarfing Ben’s head, strained against skin stretched thinner than cellophane, revealing intricate maps of veins beneath. His pecs were mountainous slabs, each easily larger than a dinner plate, resting on a ridged abdomen that looked sculpted from granite. He looked down at his own cock, a weapon of flesh thicker than Ben’s forearm. "Yours ain’t exactly subtle," he grunted, the sound vibrating the air. "Feels like it weighs ten pounds. How the fuck do we walk?"
Ben’s laugh was a low, dangerous chuckle. He wasn’t just big; he was aesthetically exaggerated – every muscle group flared with impossible definition, his waist impossibly narrow compared to his cannonball shoulders, his skin taking on an almost polished sheen under the monitor’s glow. He tossed the ruler onto the desk, scattering energy drink cans. "Walking’s overrated, beast," he grinned, a flash of white in a face now carved with sharp, predatory angles. "Besides…" His transformed eyes, sharp and glittering with a hunger that had nothing to do with pizza, locked onto Alex’s gargantuan erection. "I see something better to do."
He took a step forward. The worn carpet groaned under his immense weight, a weight that hadn't existed an hour ago. The sheer bulk of him, the raw power radiating off his frame, was primal. Intoxicating. He reached out, his newly massive hand engulfing Alex’s forearm. The difference was still staggering – Alex was raw, overwhelming force, a walking catastrophe of muscle; Ben was power sculpted into a predatory work of art. But the lust burning between them was the same.
Alex felt the heat radiating from Ben’s palm, saw the dilated pupils, the flush spreading down Ben’s sculpted neck to his own impossibly thick pecs. The ache in his own monstrous cock intensified, throbbing like a second heart. He didn’t resist as Ben pushed him backwards. He stumbled, his tree-trunk legs knocking over a stack of game cases with a plastic clatter. His back hit the wall beside the bed, the impact vibrating the plaster. Posters of pixelated heroes fluttered.
Ben closed the distance, pressing his sculpted chest against Alex’s mountainous one. The sheer heat, the slide of sweat-slicked skin over swollen muscle, drew a guttural groan from both of them. Ben’s powerful hands slid down Alex’s ridged sides, over the distended, vein-etched skin of his obliques, and gripped the colossal swell of Alex’s glutes. He squeezed, hard, fingers sinking into rock-hard meat.
"Fuck, you’re huge," Ben rasped, grinding his own grotesquely thick erection against Alex’s thigh. The sheer size of them made the friction clumsy, overwhelming. "Like trying to fuck a goddamn building." He tilted his head up, his sharp jawline brushing Alex’s pectoral. "Think your dick got bigger since I measured it?" His voice dropped to a filthy whisper. "Bet I can still take it."
Alex’s massive hand tangled in Ben’s dark hair, pulling his head back. The dominance surged through him, amplified by the terrifying power in his limbs. "You wanted monsters," he growled, the sound scraping against the walls. "Now take your fucking monster." He pushed Ben roughly to his knees. The impact made the floorboards creak in protest. Ben’s transformed face, sharp and breathtakingly handsome even now, was level with Alex’s jutting cock.
Ben didn’s hesitate. He spat, a thick glob landing on the glistening purple head. Then, with a hunger that bordered on desperation, he wrapped his mouth around the impossible girth. He couldn't take more than the swollen head and an inch of shaft. His jaw stretched painfully wide, saliva slicking the stretched skin around his lips. He sucked hard, his cheeks hollowing, his tongue working furiously over the slit.
"Christ!" Alex roared, his head slamming back against the wall. The sensation was mind-blowing. The heat, the wet suction, the sheer impossibility of that much cock in Ben’s mouth – it sent electric jolts of pure pleasure straight to his core. His hand tightened in Ben’s hair, forcing him down further, pushing past the choking gag reflex. Ben’s eyes watered, but he didn’t pull back. He moaned around the massive intrusion, the sound vibrating against Alex’s cock, sending another wave of intense sensation crashing through him. He bobbed his head, taking what little he could, his powerful hands gripping Alex’s tree-trunk thighs for leverage, his own thick cock leaking profusely onto the carpet.
Seeing Ben, this sculpted god brought low on his knees, struggling to service even a fraction of his cock, ignited something feral in Alex. Possessive. Primal. He looked down at the crown of Ben’s head, the straining muscles in Ben’s neck, the glistening spit slicking the obscene shaft. "Need more," Alex snarled, pulling Ben’s head back by the hair, freeing his cock with a wet pop. Ben gasped for air, saliva stringing from his lips to Alex’s glistening head.
"Get on the bed," Alex commanded, his voice thick with barely restrained violence. "Ass up. Now."
A shiver of pure submission ran through Ben’s powerful frame, mingling with his own desperate arousal. He scrambled up, his movements awkward with his new bulk. He practically threw himself onto the stained sheets, the cheap mattress groaning and sagging dangerously under his weight. He planted his thickly muscled forearms on the mattress and pushed his sculpted ass high into the air. The cleft between his powerful glutes was slick with sweat. His hole, still stretched from their previous encounter but dwarfed by the sheer scale of him now, looked impossibly tight, a tiny pucker against the mountainous swell of his cheeks.
Alex spat into his hand, a thick wad barely enough. He slicked his cock roughly, the shaft gleaming wetly. He spat again onto Ben’s entrance, the slick droplet landing with a faint sound. He pressed the broad, veined head against the tight ring. The resistance was immense, terrifying. Ben tensed, his powerful back muscles knotting.
"Push back," Alex ordered, his voice a gravelly rasp. He gripped Ben’s thick hips, fingers digging into the muscle like iron claws. "Take it. Now."
Ben grunted, a sound of effort and surrender, and shoved his hips back hard. A sharp cry tore from his throat as the massive head breached him, stretching him wider than ever before. Alex felt the incredible clench, the burning heat, the impossible tightness yielding around his monstrous girth. He pushed forward, slowly, inexorably, inch by agonizing inch of thick, veined cock forcing its way inside. Ben’s body shook violently, his knuckles white against the sheets, ragged cries escaping him with each incremental invasion.
"Fuck! Alex! So… fucking… big! Ripping me!" Ben choked out, his voice distorted with pain and overwhelming pleasure. "Feels… like you’re splitting me in half!"
Alex buried himself to the hilt, his massive balls finally slapping against Ben’s ass. He paused, panting, feeling the incredible vice-like grip of Ben’s body around his cock, the heat radiating deep inside him. Ben was panting, trembling, his powerful body stretched obscenely wide around Alex’s inhuman bulk. Alex leaned forward, his immense chest pressing against Ben’s sculpted back, his lips finding Ben’s sweat-slicked neck. He bit down, not gently, marking the skin. Ben moaned, a long, low sound of submission that vibrated through their joined bodies.
Alex pulled back slowly, the thick shaft dragging along Ben’s sensitized inner walls. Ben gasped. Then Alex slammed forward again, a brutal, powerful thrust that drove Ben’s face into the mattress. He set a punishing pace – deep, powerful strokes that rocked the entire bed frame, threatening to collapse it. The sound was obscene: the wet slap of flesh colliding, the rhythmic groan of the abused bedsprings, Alex’s guttural grunts, and Ben’s desperate cries that became increasingly incoherent.
"Fuck yes! Harder! Fuck me! Split me open!" Ben screamed into the sheets, pushing back frantically against each thrust, his own huge cock bouncing wildly beneath him, leaking onto the mattress. "Your fucking monster cock! Own me!"
Alex roared, pistoning harder, deeper. He felt Ben’s inner muscles clamp down in a powerful, rhythmic spasm around his buried shaft. Ben’s cries peaked, turning into a wordless howl as his own colossal cock erupted, thick jets of cum splattering the crumpled sheets beneath him. The intense milking sensation triggered Alex’s own cataclysmic release. He bellowed, a sound like tectonic plates shifting, and slammed impossibly deep, burying himself as his cock erupted. Thick, scalding ropes of cum flooded Ben’s depths, pulsing again and again, filling him far beyond capacity.
They collapsed in a sweating, panting heap of monstrous muscle and tangled limbs, the bed groaning ominously. Alex’s softening cock remained buried deep inside Ben, both of them utterly spent. The room smelled like sex, sweat, ozone, and something metallic, like hot iron. Ben trembled beneath him, his powerful body slick and heaving.
Alex slowly, carefully pulled out. A slick mixture of cum and lube gushed out of Ben’s stretched hole, pooling on the sheet. Ben groaned, turning onto his back, his transformed chest rising and falling rapidly. His sharp, beautiful face was flushed, eyes glazed. He looked wrecked and impossibly satisfied.
"Holy… fuck…" Ben breathed, each word a labor. He reached down, wincing slightly, and touched his gaping, cum-leaking hole. "Think you ruined me for anything normal, ever again."
Alex managed a grunt, rolling onto his back beside Ben, the mattress groaning under their combined, inhuman weight. His gaze drifted past the cum-stained sheets, past the scattered debris of their transformation – discarded clothes ripped apart by swelling muscle – and landed on the monitor. It was still glowing, the serene forest scene flickering slightly.
