Bored and horny siblings Michelle and her stepbrother find themselves alone together. Michelle starts by fingering her wet pussy and stroking her big ass, but gets caught by her stepbrother. They argue, but soon they're masturbating openly in front of each other. Michelle's eyes widen at the sight of his thick, straight, huge cock. She fantasizes about feeling it inside her tight cunt, and just as they're about to act on their mutual desire, someone enters, forcing them to abruptly stop.
