Yuu sincerely blessed the girl who seemed happy to have a boyfriend. Therefore, she often invited him over for meals and, as a mother, warmly watched over the young couple. However, on the other hand, she also felt loneliness. Dissatisfied with her diminishing marital life, which was the opposite of her daughter's growing femininity. Yuu, forgetting that her daughter and her boyfriend were in the next room, indulged in self-pleasure. So absorbed in her pleasure, she did not notice her daughter's boyfriend peeking in with an excited look, and with bold movements, she provocatively teased him.
