"If nothing is done, we will lose interest in each other as the opposite sex." We met an alumnus of a university circle as a junior and got married. My wife has only male experience with her husband, and she has few SEX variations and made efforts such as watching AV with her husband, but from 5 years ago she has become SEX-less. At that time, I decided to draw the bodies of men and women with my wife and male students as models at work. I was excited to see my wife who was shy in the eyes of many people, and I could not suppress the delusion that my wife was held by other men.
