Congratulations!! [Yuko Shiraki] Takara Eizo exclusive actress work! Part (1)!! Yuko, who lost her husband at a young age, lived with her daughter and her husband. She got along well with her daughter's husband, Naoki, and lived an ordinary but happy life. One day, Yuko witnesses her daughter and Naoki arguing about sex. It seems that her daughter doesn't like sex, and keeps refusing even when Naoki asks her for it. Worried, Yuko talks to her daughter, but she doesn't listen to her. Then, by chance, Yuko comes across Naoki comforting himself. Shocked and upset, Yuko takes an unexpected action. "My responsibility as my daughter is also my responsibility as her mother..." Yuko grabs Naoki's penis. At first, it was only supposed to be a handjob... but then it was a blowjob... and even sex... Yuko desperately resists Naoki, who can't stop...
