Bored siblings, Michelle and her stepbrother, find themselves alone and horny. Michelle retreats to the bathroom, masturbating furiously, her fingers plunging into her wet pussy while she strokes her big ass. Her stepbrother walks in, catching her mid-act, and they argue heatedly. Later, they make amends, masturbating openly in front of each other. Michelle's eyes widen at the sight of her stepbrother's thick, straight, huge cock. Just as they're about to act on their mutual desire, someone enters, forcing them to abruptly end their erotic encounter.
