Mommy is cleaning the bathroom before going out for the night. She is angry that the men of the house have left it in such a mess. Then she turns round to see her stepson has snuck into the bathroom and is spying on her wearing her lingerie. She puts on her dress, but seeing how aroused he is decides to give him some encouragement in his jerking off. She reveals her tits, then begins to get aroused herself, fingering her pussy to climax, at which point he showers her nice clean dress in his sticky white cum, leaving Mommy all messed up for her night out.
