In a cramped, dimly lit room, a lone man, his cock already hard and dripping, sets a timer. He's got one minute to make a mess, and he's ready. His strokes are steady, his grip tight, his breath ragged. The room fills with the scent of sweat and pre-cum. Thirty seconds left, his hips thrust forward, his abs clench, and he lets out a guttural groan as his cock pulses, spilling rope after rope of hot, thick cum onto the floor.
