Sakurai has a difficult and easily frustrated husband, especially when it comes to matters in the bedroom, perhaps due to work pressure. This makes her feel very uncomfortable and sometimes even desiring sexual intimacy. Therefore, many nights she has to masturbate to satisfy her own physical needs. However, that is still not enough, she always dreams of having a man who can help her fulfill the desire that has been building up in her body for so long. Fortunately, that wish came true when her brother-in-law, who was lustful, moved from the countryside to live with her brother's family.
