The stepmom is caught without a towel in the bathroom, but the only one home is her stepson. She calls him over, and he reluctantly hands it to her, but he can't stop staring at her big tits. When she realizes this, it turns her on, so she does everything she can to get him hard, and they end up fucking when no one is watching
