Keiko lives with her son after her husband died. My son has grown up and recently I'm conscious of myself as a woman. At that time, I decided to be a mother of my son's friend Matsuda for a day. While taking care of Matsuda, who has no parents, he had a bad relationship with him and awakened the desire he had long forgotten. Keiko's naughty foolery that trembles with the joy of the body.
