Kneeling, hands bound behind her back, a submissive beauty is ordered to service her mistress' cock. She looks up, eyes filled with desire and trepidation, as the massive, throbbing dick is presented to her lips. She opens wide, taking it deep, her tongue swirling around the shaft. The mistress grips her hair, guiding her head, fucking her face with a ferocity that leaves her gasping for air. Spit and pre-cum drip down her chin as she struggles to keep up with the relentless pace, her nose buried in the mistress' bush.
