Bored siblings Michelle and her stepbrother find themselves alone, their annoyance boiling over. Michelle retreats to the bathroom, her fingers dancing over her wet pussy, her big ass swaying. Caught mid-act, they argue, but later, naked and aroused, they decide to masturbate together. Michelle's eyes widen at her stepbrother's thick, straight cock, and she fantasizes about it filling her tight cunt. Just as they're about to act on their desire, an interruption forces them apart.
