It has been a year since Natsumi Ito started visiting her husband Seiichi's father, Muneo. At first, she visited him to check on him after he lost his wife, but she was drawn to his mature charm and before she knew it, her relationship with him had developed beyond caring for him. Natsumi enjoys the pleasure of a woman with Muneo's experienced sex. Unlike her self-centered husband, she is crazy about Muneo, who hits the nail on the head. The two of them no longer even use contraception.
