"At this rate, we will lose interest in each other as people of the opposite sex." Met and married as an OB of the college circle and a senior student. My wife only had male experience with her husband, and she tried to see AV as a couple because of the lack of SEX variations, but since 5 years ago, she has not had sex. At that time, at work, I decided to draw male and female bodies using my wife and male students as models. Seeing his wife embarrassed under the gaze of many people made him feel agitated, unable to control the illusion that his wife would be hugged by another man.
