Bored and alone, a horny stepsister and brother turn to each other for relief. Michelle, an ebony teen, masturbates quietly in the bathroom, her fingers delving into her wet pussy. Caught in the act by her stepbrother, they argue, but later, they decide to masturbate openly. Michelle takes in her brother's thick, hard cock, fantasizing about it inside her. Just as they're about to act, someone enters, forcing them to stop.
