The gym's isolation allows the hulking weightlifter to indulge in his secret desire, his meaty hand wrapping around his thick, veiny cock. He's rock hard now, his chest heaving as he jerks off with increasing urgency. The clank of weights and the squelch of his lubed-up hand fill the room, his moans echoing off the walls. He pictures his gym partner's tight, hairless ass, imagining fucking it raw, and with a final, guttural groan, he spills his load, rope after rope of hot cum landing on the gym floor.
