Miss M, a stern domina, dominates her male slave in a hardcore anal training session. She forces him into a chastity cage, teasing his cock relentlessly. Then, she introduces him to a world of anal pleasure, starting with a big butt plug and graduating to a giant dildo. The slave's asshole gapes beautifully, accommodating every thick inch of the toys. Miss M expertly finger-fucks his prostate, bringing him close to orgasm before denying him. She degradingly milks his cock, leaving him desperate for release.
