In a dimly lit room, a man in tight underwear strokes his throbbing erection, the fabric tenting obscenely. He turns on a mechanical phallus attached to a humming machine, pressing it against his rock-hard dick. The machine thrusts, moving his foreskin back and forth, exposing his sensitive glans. He gasps, his body tensing as the machine's speed increases. His cock leaks precum, the clear fluid mixing with the lube on his skin. With a final, shuddering moan, he sprays his load, the machine still moving, milking every last drop from his spent cock.
