I actually originally just chose the name because I wasn’t planning on doing anything H, which was meant to be part of the joke. Was just meant to be a dumb double entendre.
At that time I had already decided I wanted to do all of Kuroha’s series, but I hadn’t actually read Yuugai Shitei yet and did not know just how hard it went in that direction. Needless to say the name is less funny when I’m working on series actually about masturbation, but as they say, “oh well.”
