Kenji and his wife Karen who decided to live a newlywed life in a small apartment. My father-in-law, Toru, who is worried about such two people, came to the new house with a souvenir. At first, it was to support a young couple. However, while looking at Karen, who is beautiful and has big breasts, Toru is aroused by her desires. And when he picks up Karen by car to his workplace, Toru suddenly turns into a "sending wolf". - She sucked her overflowing breasts and knocked them down. After that, I ambushed Karen in a car on her way home every day.
