[A beautiful and mysterious bewitching woman who fulfills all of a man's desires] On the way back from dinner with Tsumugi, a designer from a client company, we had sex. I have a family, but I've grown cold towards my wife and no longer have anything to do with her. A French kiss that melts my mind. She licks my asshole without me asking. And she's a slutty mistress who's okay with any number of creampies. But then I wake up and she's already prepared breakfast, puts on my socks, and gives me a blowjob... She's convenient and doesn't ask for anything troublesome. I want to be with this woman all the time, I want to have sex with her. I'm stuck in the swamp that is Tsumugi...
