Michelle and her stepbrother find themselves alone and restless one day. She retreats to the bathroom, masturbating to pass the time, her fingers delving into her wet pussy while her other hand grips her big ass. Caught mid-act by her brother, they clash, with Michelle's anger boiling over. Later, they reconcile, and Michelle openly admires her brother's thick, straight cock as he jerks off. Fantasizing about that massive dick inside her, their tension builds until an intruder forces them to abort their erotic encounter.
