Unbeknownst to each other, friends Michelle and her stepbrother, both invited to their shared friend's house, find themselves alone and horny. Michelle, a busty ebony teen, retreats to the bathroom, fingers her wet pussy, and strokes her big ass, trying to be quiet. Her stepbrother, bursting in to shower, catches her bare and vulnerable. They argue, but the tension's palpable. Later, they make amends and openly masturbate in front of each other. Michelle's eyes widen at her stepbrother's thick, straight, huge cock. She fantasizes about feeling it inside her tight cunt. Just as they're about to act, someone enters, forcing them to abruptly end their intense, taboo moment.
