In this taboo tale, a brother and sister find themselves alone, and their boredom leads to self-pleasure. Michelle, a teen with curves in all the right places, fingers her wet pussy and strokes her big ass, while her stepbrother, overhearing, bursts in excitedly. Caught naked, Michelle's anger flares, but later, they make amends and masturbate openly. Michelle's eyes widen at her brother's thick, straight cock, and she fantasizes about it filling her tight cunt. Just as they're about to act on their mutual desire, someone enters, forcing them to abruptly stop.
