A son who is excited to reunite with his mother's friend, Iori, who has been longing for him since he was a child. After a long time, she has grown up to be an adult woman, and his secret love is burning even stronger. On the other hand, I want to feel the loneliness of my heart when I pass by my husband, but if I can't stand it, my body will pile up. Two people who can not forget the pleasure that they once tasted and greet each other for secret pleasure. I strongly want to continue the relationship as it is, but I want to feel guilty about the unfaithfulness with my friend's son.
