JUTA-059 A ploy for a bath between close family: not enough water!! Grudgingly getting into the bath with mother, my cock starts accidentally getting hard. Reiko Makihara

Mother Reiko and son Kenta have lived in a defective house. We had a problem with the water supply, so we called a contractor to fix it, but the parent and child decided to save water until the day of the construction. However, Kenta gets an erection when he sees Reiko’s naked body as she starts saving water by taking a bath with Kenta. When Reiko notices Kenta’s change, she realizes that her son is already a man.
