[A beautiful and mysterious woman, a bewitching woman who can satisfy all a man's desires] After having dinner with my trading partner, the designer Tsumugi, we had sex. Although I have a family, my relationship with my wife has cooled and we're no longer together. A tongue kiss that melts my mind. Uninvited anal licking. And she's a "super promiscuous mistress who's okay with how many times I ejaculate." Just when I thought that was how it would be, I woke up to find her had prepared breakfast, helped me put on my socks, and even offered oral sex... Convenient and without any complaints. I want to be with this woman all the time, I want to have sex with her. I'm drowning in the swamp called Tsumugi...
