When they first got married, Ai and her husband used to make love almost every day, but in recent years, her husband no longer touches her. After ten years of marriage but no children, Ai's mother-in-law constantly reminds her and threatens to kick her out of the house if she doesn't give birth to a grandchild this year. Then Ai discovered that her husband often visits a "soap bathhouse," where beautiful girls serve to satisfy sexual desires. Like a drop of water overflowing a glass, the affair of her husband and the pressure from her mother-in-law always overwhelmed Ai's mind. At this moment, the neighbor's son came to give her a souvenir gift. As she was tidying up the house, Ai was dressed quite provocatively, with sweat making her clothes cling tightly to her body, accentuating her seductive figure even more. Unable to resist Ai's beauty, the young man rushed to "claim" her body. Despite continuously saying "no," Ai's body followed his actions. Suddenly, a bold idea popped into Ai's mind, thinking that this would make all her troubles disappear. She would satisfy her long-repressed sexual desires, her mother-in-law would have a "grandchild," and her husband could comfortably continue his affair. With this decision, Ai began collecting information on all the men in the neighborhood. She chose those who seemed to have accumulated a lot of sperm, invited them over, seduced them, and had them impregnate her!
