They start by masturbating separately, Michelle fingering her wet pussy and big ass, her brother jerking off his thick, straight cock. Caught in the act, they argue, but soon, their lust takes over. Naked, they openly masturbate in front of each other, Michelle fantasizing about her brother's massive dick. Just as they're about to act on their mutual desire, an intruder forces them to halt their heated encounter.
