In a cramped, dimly lit room, a hairy, uninhibited man stands, his underpants clinging to his muscular thighs. He unzips, unleashing a thick, veiny cock, and begins to stroke. His asshole winks as he grunts, pleasure building. Suddenly, he arches his back, a stream of piss soaking his underpants, the fabric darkening. He doesn't stop, instead, he fingers his piss-soaked hole, moaning. He continues jerking, his cock head glistening, until he groans, cum pulsing out, mixing with the piss in his underpants.
