The Sannomiya couple had a big problem. The husband's sperm is low, and the possibility of a natural pregnancy is infinitely low. Of course, infertility treatment costs money, and the husband was desperate and hit his wife's spit hard. At that time, Tsubaki, who was invited to a meeting of the neighborhood association by Oshima, the chairman of the neighborhood association, receives a number of humiliations called "infertility treatment". However, Tsubaki's heart and body are in the intense pleasure that she could not get from her boring activities with her husband.
