"I've always been interested in the adult world." The first time I saw an adult video was when Mr. Kashii was in elementary school. It seems that he knew the word sex even though he was in elementary school, but he didn't know that women had sex with each other, and it was quite a shock. After that, he started watching adult videos as a hobby, and it seems that he continues to do so even after he got married. One day, I was talking about a video with my husband, and he was quite an AV freak, and I couldn't believe it.
