Michelle, oblivious to his presence, fingers her wet pussy and big ass, only to be caught mid-act. They argue, but later, they give in to their desires, masturbating openly in front of each other. Michelle's eyes widen at the sight of her stepbrother's thick, straight, massive cock. Just as they're about to cross the line, someone enters, forcing them to abruptly halt their erotic encounter.
