I entered a school that was an all-girls' school until last year, and I'm the only guy! Of course, I'm the only guy on the school trip too... I thought I couldn't make any memories because I wasn't even acknowledged at school! But then, when I was invited to a girls' room by a group of girls, I was teased a lot! Then, hiding from the teacher who came to check on us, I had a super intimate erotic development with a girl in the futon!? Furthermore, other girls also had a chain reaction of arousal at that sight!? My dick was targeted everywhere and I was creampied a lot! What was supposed to be a lonely trip turned into a super erotic development like an erotic manga!
