It is a son who makes a heart to reunion with mother's friend, Iori who loved from childhood. She has grown up to an adult woman after a long time, and her secret love is burning more strongly... On the other hand, I want to feel the loneliness of the mind by passing with the husband, and the body is overlapped if it cannot be tolerated. Two people who do not forget the pleasure that tasted once and greet secretly pleasure. I would like to continue the relationship, but I want to feel uneasy with my friend's son.
