The mature slave, her eyes downcast, awaits her master's command. He circles her, his voice a low growl, "On your knees, slut." She complies, her hands bound behind her back. He produces a leather collar, buckling it around her neck, a symbol of her submission. He orders her to open her mouth, pushing his hard cock inside. She sucks eagerly, her tongue swirling around the head. He pulls her up, bending her over, and spanks her, the sound of flesh meeting flesh filling the room. He slides a lubed plug into her ass, making her gasp, before fucking her pussy hard, claiming her completely.
