Yuna lives a married life with her husband. One day, I decided to go back to live in the same house with my father-in-law, who had quarreled with my wife and then rolled to death. My husband still has family affection, but in his heart, he can't accept it. While Yuna's dissatisfaction grows, her father-in-law's escalating sexual harassment finally crosses the line... I'm addicted to the perverted SEX with my father-in-law that I should have hated.
