A dominant woman takes control of her male slave, subjecting him to a series of degrading and painful tests. She begins by forcing him into a chastity device, keeping his cock locked away and aching for release. She orders him to service her, making him lick her pussy until she's dripping. Then, she mounts him, rubbing her ass against his trapped cock, making him beg for mercy. She responds by forcing him to eat her out again, this time until she cums, leaving him frustrated and desperate for his own release.
