In a dimly lit dungeon, a busty submissive, her massive tits straining against a lacy bra, is bound and made to kneel. Her domme, in thigh-high boots and a leather corset, teases her with a violet wand, sending electric shocks through her body, making her squirm. The sub's mouth is forced open, and a thick, gloved hand pushes inside, gagging her. She's facefucked ruthlessly, tears streaming down her cheeks, as her domme slaps her face and tits. The sub, despite the pain, is aroused, her pussy dripping. She reaches down to masturbate, but a sharp shock from the wand stops her. Her punishment continues until she's gasping, her makeup smeared, and her big tits heaving.
