"This machine will extract the cum out of that prostate"

Once the milking machine is sucking at maximum speed, Lexi slips her huge cock into the slaves ass. Now his cock is stimulated while Lexi is pressing down on his prostate with her cock. Ashley continues stroking the slaves throbbing cock while Lexi pounds his tight ass. When the slave begins to beg to release Lexi slips her finger into his ass and manually milks his prostate by pressing down on it while Ashley strokes his cock. Every last drop of semen is milked from his prostate.
