In the throes of self-pleasure, a man's body betrays his control. His asshole pulses and contracts, hungry for stimulation, as he jerks off furiously. The tension builds, and his asshole tightens, yearning for a cock to milk. As his orgasm crashes over him, his asshole convulses, milking imaginary cum from his throbbing cock, leaving him gasping and spent, his asshole still twitching with the remnants of his intense release.
