The Sannomiya couple had a big problem. My husband's sperm count is low, and the chances of getting pregnant naturally are extremely low. Of course, infertility treatment costs money, and the husband became desperate and was harsh on his wife. At that time, Tsubaki is invited to a neighborhood association meeting by Oshima, the president of the neighborhood association, and is subjected to a number of humiliations under the guise of ``infertility treatment''. However, Tsubaki's mind and body are filled with intense pleasure that she could not get from boring activities with her husband.
