A mistress asserts her female domination, transforming her submissive male into her 'chastity slave.' She trains him to serve her every whim, denying him the pleasure of release. His balls are painfully crushed under her heel, his cock caged and tormented. She humiliates him, ordering him to clean her ass with his tongue, then commands him to cum, only to cruelly reverse her order at the last second. He's left a sobbing, needy mess, utterly devoted to his mistress's every command.
