Slave P, locked in a chastity cage, is brought to Miss M's dungeon for intense anal training. She humiliates him in a CFNM setting, making him parade his caged cock before shoving his face between her legs. After he's sufficiently degraded, she turns him around and pushes a butt plug into his ass, making him walk around with it. Later, she replaces it with a larger one, stretching his asshole to accommodate her thick fingers, leaving him with a gaping, red, well-used hole.
