In a dimly-lit dungeon, two stunning dominatrices, Mistress A and Mistress B, take turns tormenting their sissyfied slave. They bind him, tease him with tantalizing touches, and force him to maintain a rock-hard erection despite his chastity device. With every cruel command, they remind him of his powerlessness, using ballbusting techniques to keep him in line. The slave's denial is palpable, but the mistresses' control is absolute, leading to a humiliating yet exhilarating session of female domination.
