Miss Ruby Marks, the reigning queen of BDSM, educates her latest conquest, Slave P, in the art of fisting. She seductively guides his hands to her luscious, curves, teaching him to worship her body before turning her attention to his. With a hunger that's almost palpable, she grips his hard cock, stroking it expertly while she whispers filthy commands into his ear. She then moves to his ass, using her expert fingers to stretch and prepare him for her thick, glistening fist. The room echoes with Slave P's cries of pleasure as Ruby Marks masterfully fists him, driving him closer and closer to the edge of ecstasy.
