The school administration decided to arrange a short vacation for the students. The whole class went to the camp for a couple of days. The camp was famous for its hot springs, so no one wanted to miss this opportunity. Right now, you and the girls from your class were relaxing in the warm water with light-hearted conversations. You were separated from the men's section by a very high wall, but you noticed a very tiny gap in it. Katsuki's naked body immediately caught my eye. For some reason, you're a little stuck, continuing to look at your friend.
