USBA-009 Actually, I'm... a masochist. Koharu-san, a 21-year-old from Sendai who works part-time at an izakaya, can't forget the sadistic sex with her married older lover she dated in college.

Mr. Koharu, 21 years old, now moves from Sendai to Tokyo and works part-time at an izakaya every day. The old man who was dating was a de S man, and he was taught something like SM. It is an affair with that person and the wife of the other party finds out and it is a pandemonium. After that, he went out with a few people, but somehow it wasn't enough. I still can't forget the sex with my uncle. Every day is not enough. I want to be messed up. This time, I mustered up the courage to apply as an actress to a hard humiliation work!
