In the throes of a deserted moment, a man's primal urge takes over. He unbuckles, letting his pants drop to the floor, and grips his hardening cock. Stroking slowly, he feels the familiar rhythm, his breath hitching as pleasure builds. His other hand reaches down, cupping his balls, rolling them gently. The sensation intensifies, and he knows what's coming. He leans back, aiming as his piss flows, mixing with his pre-cum, lubricating his thrusts. The room fills with the sound of his grunts and the smell of his release.
