Bound by a locked device, he's at her mercy, the key gleaming tantalizingly from her fingers. She strokes his straining cock, whispering taunts, "You better hope I don't lose the key." His humiliation grows as she denies him release, edging him closer to the brink only to withdraw, leaving him aching and desperate. In this BDSM power play, the Femdom takes control, relishing his torment, as the chastity device becomes both his prison and his tormentor.
