Isabella Lui, the stern German mistress, orders her reluctant slave, Joschi, to drink the used condoms of her former lovers. In a scene of degrading submission, Joschi gingerly opens the filled condoms, the scent of other men's cum filling the air. Isabella watches, cruelly amused, as he tentatively licks the semen before gulping it down, his face contorting in disgust. The room is filled with the sounds of his reluctant swallowing, the only break in the tension the occasional smack of Isabella's hand against his cheek.
