Shoko Takahashi has been married for two years but has no children. Due to a job change, she and her husband moved back to live with her husband's parents. Shoko's father-in-law is a rather perverted old man and she felt it when she came to stay with him for a few days. He casually walked around the house without clothes, making Shoko extremely embarrassed. And one day, he whispered into his daughter-in-law's ear and said: “Dad, help me get pregnant!”.
