Mr. Tos, a straight guy, finds himself tricked into a pegging session by his bratty step-sister, Masseuse. She's a financial domination specialist, and he's her new victim. She starts by humiliating him, making him worship her fat ass and tiny clitty. Then, she straps on a massive dildo, pushing him onto his back and sliding her enormous strap-on deep into his virgin ass. He moans in pain and pleasure as she rides him, straight to the ass, punishing him for his past mistakes. She finishes by making him lick her booty clean, leaving him a shaking, humiliated mess.
