A slave, bound and gagged, is presented with a choice: suffer in chastity or serve his mistress with his mouth. He chooses the latter, eagerly lapping at her wet pussy, desperate for any taste of pleasure. But his mistress is not so easily satisfied. She denies him release, again and again, bringing him to the brink of orgasm only to pull back, leaving him begging for mercy. In a final act of humiliation, she locks him in a chastity device, leaving him to suffer in his own juices, a reminder of his place and her power.
