In a dimly lit dungeon, the submissive slut, ass high and ready, awaits Master's friend. He enters, his massive BBC leading the way, a cruel grin on his face. He runs a thick, gloved finger around her puckered hole, making her shiver. Grabbing a nearby bottle of lube, he coats his cock, pressing it against her entrance. She pushes back, eager to feel him inside. He pushes in, inch by inch, filling her, claiming her ass. He fucks her relentlessly, his pace quickening, his grunts echoing in the room as he uses her for his pleasure.
