The locker room hummed with the distant echo of showers and the low buzz of fluorescent lights. Jake, a scrawny 22-year-old twink with narrow shoulders, pale skin, and a nervous energy, had slipped in after hours with a single forbidden artifact around his neck: an ancient sun-shaped amulet he’d stolen from a shady occult shop. He’d spent weeks fantasizing about this moment, staring at guys like Derek.
Derek was the undisputed alpha—6’4” of pure, veined muscle, broad chest glistening with sweat, thick arms that could bench twice Jake’s bodyweight, and a cocky smirk that made weaker men look away. Curly dark hair, a trimmed beard, and a physique carved from years of heavy lifting. He stood shirtless in front of his locker, black shorts slung low on his powerful hips, admiring his own reflection.
Jake stepped out from the shadows, heart pounding. “Hey, big guy.”
Derek turned, eyebrow raised. “The fuck you want, twig? Wrong locker room?”
Before Derek could laugh him off, Jake clutched the amulet. A surge of purple energy crackled to life in his palm, hungry and alive. He lunged forward, slamming his hand flat against Derek’s rock-hard chest.
“What the—?!” Derek’s words cut off in a strangled gasp as the lightning exploded between them. Violet arcs of power surged from Derek’s body into Jake’s, flowing like liquid fire. Derek’s massive frame arched backward, muscles convulsing, his handsome face twisting in shock and unwilling pleasure. His thick pecs flexed hard under the assault, nipples hardening as the energy ripped through him.
“Oh fuck… yes,” Jake moaned, his voice cracking higher at first, then deepening. He could *feel* it. Derek’s raw power pouring into him—every ounce of size, strength, and masculine perfection.
Derek’s broad shoulders began to shrink. His once-impossibly wide back narrowed as the energy drained away. His heavy traps deflated, his cannonball delts softened. Veins that had pulsed across his biceps receded while Jake’s arms swelled before his eyes. Jake’s skinny limbs ballooned outward, veins rising like ropes, biceps peaking into thick, striated mounds that rivaled what Derek had just possessed.
“N-no… my gains… give them back,” Derek whimpered, his voice growing lighter, weaker. His abs, once an armored eight-pack, faded into a softer, flatter stomach as the stolen power reshaped him. His thick chest caved inward slightly, losing its proud shelf, while Jake’s torso exploded with growth. Jake’s narrow ribcage widened dramatically, heavy slabs of pectoral muscle pushing outward, forming deep cleavage. His nipples thickened and darkened. A perfect, deep-cut six-pack—then eight—carved itself across his midsection as the energy crackled lower.
Jake groaned in ecstasy, his shorts tenting obscenely as his cock lengthened and thickened, stealing Derek’s impressive endowment. His ass rounded out into powerful glutes, legs exploding with quad sweeps and diamond calves. Even his face transformed: jaw sharpening into a square, masculine line, stubble sprouting thick and dark, lips fuller, eyes gaining that same cocky, predatory glint Derek once owned. Curly hair filled out on his head. Sweat glistened over his new, bronzed, godlike physique.
Derek, meanwhile, had been reduced to a lean, trembling shadow of himself. Still fit, but now wiry and twinkish—narrow shoulders, smooth chest with visible ribs, a flat stomach, and a much smaller bulge in his orange shorts. His cap sat loose on his head, his once-proud beard reduced to light scruff. He slumped against the lockers, panting, utterly drained and strangely, shamefully aroused.
Jake flexed his new massive arm, watching the peak rise like a mountain. He ran a hand over his thick, heaving chest, fingers brushing the glowing amulet now resting perfectly between his powerful pecs. “Holy shit… look at me.” His voice was a deep, resonant baritone. He stepped closer, towering over the former alpha, and cupped Derek’s chin with one huge hand.
“You feel that, little guy? That’s *my* size now. My strength. My looks.” Jake’s free hand drifted down to grope his own massive thigh, then reached out to teasingly flick one of Derek’s diminished nipples. “Thanks for the donation.”
Derek could only whimper, a mix of humiliation and lingering electric aftershocks making his smaller body twitch. Jake smirked—the same smirk that used to belong to Derek—and struck a double biceps pose, the purple energy fading as the transfer completed.
The new alpha looked down at his drained conquest. “Don’t worry. Maybe I’ll let you worship the body you built… if you behave.”
Jake left the locker room walking taller, broader, and unstoppable, while the former muscle god slumped on the bench, forever changed. The amulet pulsed warmly against Jake’s chest, already hungry for its next victim.
