My wife, Yumi, has been married for 10 years. My recent husband is busy with work, and the couple's night activities have become almost non-existent. One day I will be indulged in masturbation on the sofa alone. One day, my husband invites Tanaka, who is a subordinate, to his house. Yumi, who talks to an energetic young man for the first time in a long time, can not suppress the growing feelings and hides from her husband and takes Tanaka to the bedroom.
