The mistress, her big tits bouncing, takes charge, tying her muscular slave to a chair. She teases him with two strap-ons, running them along his naked body, making him squirm. She lands hard spanks on his ass, leaving it red and tender. Grabbing a dildo, she roughly pegs his boy-pussy, her thick fingers massaging his prostate. He moans, trying to hold back, but she's relentless. She switches to the second strap-on, fucking him harder, making him beg for release. With a final, hard thrust, she sends him over the edge, his cock pulsing as he cums, his prostate orgasm consuming him.
