In the dimly lit, empty gym, a twink jock, his muscles glistening with sweat, can't resist the temptation to stroke his massive, throbbing cock. He grunts and moans, his hand flying up and down his rigid shaft as he leans against the weight bench. The room fills with the sounds of his heavy breathing and the slapping of his flesh. His grip tightens, and with a final, powerful thrust, he unleashes a torrent of cum, coating his abs and the floor.
