A vulnerable crossdresser, bound in chastity, listens intently as their femdom mistress gets passionately fucked in the next room. The sissy's ears perk up at every moan and slap of skin, their own cock straining against the confines of their cage. The femdom, aware of the sissy's torment, ensures her lover is loud and rough, prolonging the crossdresser's humiliation. Occasionally, she visits the sissy to taunt them, rubbing her lover's cum on their face before locking them away again.
