Mother Mirei decides to stay at her daughter's house to go sightseeing in Tokyo. When I talked about my daughter's childhood friend's marriage and pregnancy, my daughter's face became cloudy and I left my seat. According to his son-in-law, the couple are on good terms, but there is no night. Mirei was worried about various things, but I was struck by the fact that she was a married couple. When I open my daughter's room after taking a bath, I witness a son-in-law masturbating in Mirei's underwear. My son-in-law, Mirei, who is in a hurry at a sudden thing, is not a daughter, so I feel sorry for her because she is not a daughter, and she makes her squid with a mouthful.
