A caged sissy, locked in chastity and desperate for release, is at the mercy of his cruel mistress. She unlocks his cage, not to grant him pleasure, but to use his throbbing dick for her own satisfaction. She makes him lick her boots, then pushes him down, forcing his tongue into her ass. She mounts him, riding his cock hard, making him beg for mercy. But she's not done yet. She turns him around, slapping his ass and spitting on his hole before shoving his dick back into her, fucking him until she's satisfied.
