A stern mistress takes her male slave through a rigorous femdom training, focusing on ballbusting and chastity. She commands him to strip, revealing his caged cock, and orders him to kneel before her. She grinds her heels into his testicles, causing him to gasp and squirm. "You will learn to respect my power, slave," she growls. She makes him crawl, following her every command, before leading him to her bed, where she positions him for a humiliating cum-eating lesson. She strokes his cock until he's on the brink, then forces him to hold back, only allowing him to release once she's satisfied with his obedience.
