Taboo Temptations in the Closet

A brother and sister, bound by blood and boredom, find themselves alone and horny. She sneaks into the bathroom, fingers her wet slit, and strokes her big ass, trying to be quiet. He bursts in, catching her bare and vulnerable. They argue, but later, they masturbate openly, their lust growing. She fantasizes about his thick, straight cock plunging into her tight pussy. Just as they're about to act, someone enters, forcing them to abruptly end their erotic encounter.
