In a private dungeon, Lucy Hart eagerly awaits Sarah Diavola, her mistress for the evening. Sarah enters, her body encased in a form-fitting latex bodysuit and sheer pantyhose, a strapon already secured to her hips. She orders Lucy onto her knees, feeding her the strapon's length until Lucy gags, tears streaming down her face. Sarah, her own arousal evident, guides Lucy onto an upright fucking machine, securing her wrists and ankles, leaving her completely at Sarah's mercy. She activates the machine, watching Lucy's body writhe and buck as the strapon penetrates her depths.
