Nanao, a female teacher married woman who decided to go on a preview of her school trip. I was very opposed to staying with people living in the world of teaching, which is "many insidious people", but I can't help it because it is a job. No matter how many men and women, something doesn't happen in just one night and two days, so it's useless to worry. No way ... I've never had sex ... Isn't it?
