Steve was a 68-year-old man living alone. At 170 cm tall and barely 52 kg, he was painfully thin—bones jutting out, skin loose and sagging. He’d never been athletic, even in his youth, and after losing his wife twenty years ago, he’d spent decades in quiet solitude. No kids, no friends left. His libido had vanished long ago; touching himself brought no feeling at all. He was just getting by, day after day.
One day, a door-to-door salesman talked him into buying a bottle of “patented health supplements” for seniors. “Take one a day and you’ll feel the energy come back.” On impulse, Steve bought it and started taking one pill every evening.
Day 7A week in, he noticed a subtle change. His weight crept up to around 60 kg, skin tightening a little. His chest filled out slightly, faint muscle outlines appearing in his arms. Abs hinted at showing through, thighs feeling firmer. That night, lying alone, he felt a faint warmth down below for the first time in years. His cock twitched half-hard, veins pulsing gently. He brushed it lightly—now about 15 cm, warm and responsive. “Hmm… blood’s flowing again…” he muttered, leaving it at that. No urge to finish, but the faint heat made him feel alive, just a little.
Day 30A month in, the changes were clear. Weight hit the mid-80s kg. He’d shed the skeletal look, filling out like a healthy middle-aged man. His chest swelled into thick slabs, shirts pulling tight across them. Shoulders broadened, back thickening. Veins popped on his forearms as they thickened, six-pack carving in sharply. Thighs solidified, giving him real strength when he walked. His cock hung over 20 cm soft, hardening to nearly 30 cm—rock-solid. Balls swelled a bit, seed production ramping up. That night it stood rigid on its own. Steve reached down instinctively, wrapping both hands around the shaft and stroking slowly up and down. The head flushed deep red, swelling as veins throbbed under his palms. “Nngh… it’s… so hard again… burning hot…” His breathing quickened as he sped up. Thumb pressing hard into the slit, pre-cum leaked steadily, slicking his grip. Balls churned, pulling tight. Over an hour of firm, piston-like strokes and the first load hit. “Grr… coming…!” Cum shot hard, splattering the wall—over 500 ml. Hot seed coated his hand and belly, body shuddering. But the erection held. He gripped again, stroking through the mess for a second, then third release. The room filled with the thick scent of cum.
Day 50Day 50, he rivaled pro bodybuilders. Weight in the 120 kg range. Chest like steel plates, shoulders and back so wide he brushed doorframes. Forearms veined and thick as thighs, eight-pack etched deep. Legs ballooned, pants ripping at the seams. Cock 30 cm soft, 40 cm hard—unyielding steel. Pre-cum leaked freely, balls heavy. Desire hit hard; multiple sessions a day became necessary. Morning erections demanded attention. Steve lay back, both hands clamping the shaft, pumping fast and hard. He ground his palm into the swollen head, fingers tracing bulging veins. “Grr… fuck… so thick my hands barely close… head’s huge… leaking already…” Balls swung heavy, churning audibly. Hours of relentless stroking built to explosion. “Rrrgh… shooting…!” Nearly a liter erupted in thick ropes, arcing high. Hot cum splashed his chest and face, muscles clenching in waves. Erection unflagging, he started again immediately—round after round.
Six Months InSix months, he crossed human limits. Weight over 200 kg. Pure muscle packed everywhere—chest and back massive, arms and legs like tree trunks. Ten-pack abs like carved stone. Cock 50 cm soft, over 70 cm hard—veins roping thick. Balls basketball-sized, seed factory on overdrive. Desire constant from dawn to dusk. Steve sat on the floor, massive hands gripping the shaft. Both couldn’t fully encircle it anymore. He started slow, building to furious speed—twisting the head roughly, pumping the length like a machine. Pre-cum poured in streams, soaking everything. “Grr… haah… cock’s… enormous… burning… seed boiling inside…” Balls throbbed, heavy and full. Hours in, climax hit. “Rrrgh… pouring out… all of it…!” Nearly 2 liters blasted out, hosing walls and floor. Hot seed pooled around him, scent overwhelming. Erection held—he gripped again, grunting through dozens more loads.
One Year LaterA full year, the final monstrous form. Weight nearing 340 kg. Height still 170 cm, but volume superhuman—chest like armored plates, shoulders too wide for doors, arms and thighs exploding with muscle. Skin stretched drum-tight, every ridge visible. Cock over 60 cm soft, well past a meter hard. Head swollen purple-red, pre-cum gushing like a faucet. Balls immense, endlessly producing.
Desire total takeover. Steve spent whole days with huge hands clamped on the monster cock, stroking savagely. Both hands barely covered the girth—he pumped like a piston, twisting the head viciously, fingers digging into veins. Pre-cum flooded, turning everything slick. “Grr… haah… cock’s… too big… throbbing… seed… rising…!” Balls churned loud, pumping load after load. Hours built to eruption. “Raaargh—! Exploding… everything… fuck…!” Over 3 liters shot in powerful jets, coating walls, ceiling, body. Thick ropes splashed hot against skin, muscles flexing hard in ecstasy. Scent choked the air. Erection never faded—he growled low, gripping again. “Still… more… gotta come…” Dozens of orgasms followed, cum pooling ankle-deep, each pulse making muscle swell tighter in primal bliss.
Steve was now a slave to raw need. That one pill had slowly rebuilt the skinny loner into a hyper-muscular, insatiable beast. Day after day alone, lost in endless stroking, he sank deeper into this primal, filthy ecstasy. There was no end in sight.
