Hidden behind a two-way mirror, a dominant woman observes her submissive partner as he masturbates at her command. His hand moves tentatively at first, but as her voice echoes in his ear, telling him to imagine her touch, her taste, his strokes become more urgent. She watches, her own arousal growing, as he struggles to maintain control. His body tenses, his breath hitches, and she knows he's close. "Not yet," she whispers, her voice a whiplash of control that sends shivers down his spine. He whimpers, his hand stilling, awaiting her next command.
