A big-titted mistress takes control, tying her slave to a bedpost. She orders him to watch as she plays with her tits, teasing him with her nipples. Then, she turns him around, spanking his ass until it's bright red. She lubes up her strap-on and pushes it into his ass, fucking him hard and rough. She slaps his ass, making him groan as she pegs him, her tits bouncing with each thrust. She rides him until they both cum hard, leaving him tied and spent.
