A strapping, straight-acting male strips down to his briefs, his muscular body glistening with sweat. He strokes his hard, uncut cock through the thin fabric, feeling it pulse and grow. He tugs down his underwear, letting his thick, veiny shaft spring free. He grips it firmly, his calloused hands working it expertly. His grunts fill the room as he jerks off, his body tensing as he nears climax. He spills his load, his cum shooting out, coating his abs.
