Mistress Joslyn James, a seasoned dominant, takes on Sarah Jessie in a rigorous chastity training session. Joslyn teases Sarah with her foot, running it along her captive cock, while Sarah, locked in a steel cage, begs for release. Joslyn, however, is merciless, pushing Sarah's limits with ball-busting kicks and cruel laughter, all while Sarah, humiliated and horny, endures in her cuckold role.
