The gym’s locker room steam hung thick and warm as Ethan stepped into the far shower stall, the one with the busted curtain that never quite closed. The place was mostly empty this late in the afternoon—just the low hiss of water and the distant clang of weights two rooms over.
He tipped his head back, let the scalding spray pound his shoulders, eyes closed. Soap suds slid down the ridges of his abs, tracing the sharp V that disappeared beneath the waistband of his black compression shorts. Routine. Comfortable. Mind already drifting to the protein shake waiting in his bag.
A sudden, molten heat bloomed low in his pelvis—like someone had poured warm honey straight into his core. His breath caught. He braced one palm against the wet tile, half-laughing at the absurdity. Muscle cramp? Bad lunch? But the heat didn’t fade. It swelled. Deepened. Turned liquid and urgent.
His flat, hard-earned stomach was already rounding. Not subtly. Visibly. The skin stretched smooth and taut, the navel beginning to pop outward as though something insistent was pressing up from inside. He stared, mouth open under the pouring water, cock twitching hard against the soaked fabric.
Another pulse. Stronger. His belly surged forward in a single heartbeat. The sensation wasn’t pain—it was pressure, yes, but the kind that made his thighs shake and his breath hitch in short, needy gasps. Fullness. Stretching. Alive.
He cupped both hands under the curve instinctively, trying to hold it, slow it. Useless. The skin was fever-hot, drum-tight, and still growing. He could feel it—whatever was inside—rolling, shifting, pressing outward with deliberate, rhythmic insistence. Each swell pushed his erection harder against the elastic until the waistband dug into the sensitive underside.
The word slipped out unbidden. He didn’t even try to stop it.
Water cascaded over the impossible dome of his abdomen. It jutted proud now, heavy, unmistakably pregnant—full-term and beyond. Stretch marks bloomed like pale lightning across the sides in real time. He dragged trembling fingers over them, awestruck, dizzy with how sensitive every inch had become. Each brush of his own palm sent sparks straight to his groin.
He was leaking—pre-cum soaking through the front of his shorts in dark streaks—but he couldn’t bring himself to touch his cock yet. Not yet. He needed both hands on this. On the life that had erupted inside him so impossibly fast.
Another powerful roll from within. He moaned—loud, shameless, the sound bouncing off the tiles. His knees buckled; he caught himself against the wall, forehead pressed to cool ceramic while his belly continued its relentless expansion. The skin gleamed under the water, so tight it looked lacquered. He could see the faint outline of movement beneath—elbows, knees, a tiny foot pressing outward, making the surface ripple.
He laughed again, breathless, delirious.
“I’m—fuck—I’m pregnant. I’m so fucking pregnant—”
The words alone nearly tipped him over the edge.
He finally gave in. One hand stayed splayed across the apex of his belly, feeling every kick, every squirm, while the other shoved his shorts down just enough to free his aching cock. The cold air hit wet skin and he hissed. Two strokes—hard, desperate—and he was already trembling on the brink.
Inside him, the pressure built to a crescendo. Not labor. Not yet. Just… arrival. Completion. His entire body sang with it.
He came with a broken shout that probably carried into the locker room. Thick ropes painted the underside of his own swollen belly, mixing with the shower water and sliding down the obscene curve. His knees gave out completely this time. He sank to the floor, back against the wall, legs splayed, water still pounding down, cradling the impossible weight of himself.
Chest heaving. Cock still twitching against the hot, heavy dome that hadn’t stopped moving.
And god help him… he was already wondering how much bigger he could get before someone found him.
