From Yaoi Is Life:

One day, I wondered about people’s anal sex fantasies. Attempting to inject as much realism to a fantasy as possible, I decided to make the main character of this story a sex service addict. But he works at a book store? The more I think about it, the more complicated it gets. Would that even make an entertaining story? Can the seme make up for the useless uke? ...That’s what I thought as I drew this. There are many kinks I sadly was unable to include in this story. When I got the first version back, I realized that because of the corrections, everything around the genitalia disappeared… But what upset me most was how all the pubic hair vanished!
