On the way back from dinner with Tsumugi, a designer from a client company, we had sex. I have a family, but my relationship with my wife has grown cold and I no longer have a relationship with her. She's a French kiss that melts my brain. 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, helped me put on my socks, and gave me a blow job... It's convenient and troublesome...
