In a room filled with the scent of leather and sex, a dominant woman commands her submissive to assume the doggy position. The sub, her ass high and vulnerable, feels the cold touch of a vibrator on her puckered hole, then the warm, wet sensation of her mistress's tongue. She moans, muffled by the gag, as the vibrator is replaced by a dildo, her mistress's strong hands gripping her hips, pulling her back as she's drilled, her ass cheeks slapping against her mistress's thighs, her humiliation complete as she's used for her mistress's pleasure.
