My whore of a chastity slave is in for a rough ride. Taunting him with the key to his chastity device, I fuck his ass with my huge black cock mercilessly, his fuck-hole as I tell him that this railing is for nobody's pleasure but mine.
Its his duty to get me off and nothing gets my rocks off like pounding slave ass! When I'm satisfied, I shove the key to his chastity device up his sore ass for safekeeping.
