Miss M's gloved hand disappears into her slave's ass, the tightness yielding to her expertise. She twists and curls her fingers, stimulating his inner walls, as he grunts and moans, his cock dripping pre-cum onto the cold floor. His belly distends, a grotesque yet alluring sight, as Miss M fisted him deep. She pumps her hand, fucking his ass, and he explodes, his body convulsing as he sprays ropes of cum, his anal whore training complete.
