Mrs. Smith, a dominant figure in their BDSM relationship, commands her husband to bend over. She lubes up her hands, then begins to fist her husband's ass, her entire hand disappearing inside him. She twists and turns, exploring every inch of his ass, her fingers finding his prostate and sending waves of pleasure through him. She expertly milks his prostate, drawing out a creamy cumshot, his prostate orgasm intense and satisfying. She withdraws her hand, his ass gaping, and feeds him his own cum, marking him as her submissive.
