In the sultry heat of the afternoon, a brother and sister, both restless and horny, find themselves alone in the house. Michelle, a busty ebony teen, starts by masturbating quietly in the bathroom, her fingers exploring her wet pussy, while her brother showers nearby. Caught in the act, they argue, but later, driven by their forbidden desires, they decide to masturbate openly in front of each other. Michelle's eyes widen as she takes in her brother's massive, throbbing cock. Just as they're about to give in to their taboo lust, a sudden noise forces them to halt their erotic encounter.
