A vulnerable beauty, bound and gagged, is subjected to a fierce flogging by her dominant lesbian partner. Her head secured inside a steel box, she can only hear the whistle of the whip and feel the intense sting on her exposed flesh. The mistress, fueled by missogyny, relishes in her power, savoring every cry muffled by the box. The bound woman's body, marked with red welts, trembles with pain and arousal, her nipples hard with submission.
