Kozue, a 31-year-old married woman who has a dignified and neat feeling. She has been married to her husband, who works for a copier sales company, for four years. However, her husband, who is 10 years older than her, seems to have a peculiar habit, which demands only onanism and oral sex every night and does not insert anything at all. For Kozue, who wants her child, her troubled days continued. In her frustration that she would grow old without being able to have children, she saw a classified advertisement for looking for a married woman with a desire to have an affair, and made up her mind to apply. Her journey of adultery is a mixture of anxiety, guilt, and anticipation, and her chaste wife is puzzled by her own lewdness that she didn't notice until now...! !
