When I was in high school I used to share intimate caresses during class with some of the girls. That aroused me a lot (needless to say). One time, this girl was caressing me and I was called to submit homework and I had to stand up before everybody. I was worried so what I did was to make my desk fall and grab my backpack to cover my boner. It worked and I don't remember anyone noticing it. It soon disappeared.
