Though I'm married, I've never been popular with women, and now I'm what they call a middle-aged man, a humble person who is treated coldly by society and my wife. I just go to work, earn a decent amount, and come home to a house where I'm not welcomed. One day, a beautiful woman named Konan Koyoi appears in this gray life. My only enjoyment recently has been working with her, who is good at doing business with clients, but as the project is coming to an end, this relationship begins. Overwhelming maternal love, a devoted woman, good sex, and beautiful big breasts that are second to none. From a gray world to a rosy life of affairs.
