I go to school in a conservative state so I think I fit the criteria of this thread and I really want to tell people about it because I think its super hot. I'm currently in my junior year of college and I was in my second class of the day. I always sit either in the first or second rows because I like to do well in school, keeps me away from distractions. However, I just got new underwear yesterday and I was feeling very horny in class. I got hard, and instead of just letting it pass, I was rubbing it through my pants. I'm in the very first row in the class, right by my team partner. The second row directly behind us was mostly empty due to lack of attendance, and the front row where I sit has a front on the desks so you can't see anyones legs. I turned my back to my group partner and put my backback on the opposite chair to stop anyone who might accidentally see what I was doing. I started slow, and quickly realized just how horny I was. While my teacher was lecturing, I put in an earbud and played gay porn, just for me to hear. I was discreetly stroking, or I guess slightly rubbing my hard on. I've been horny in class and rubbed myself a couple times, but never to the point of completion. Today though, I kept rubbing my pants until I couldn't stand it anymore and I took it out of my pant leg and stroked until I finished on the floor. My group partner never knew, my teacher never knew, my other classmates never knew, but I knew. It was so hot cumming in public with everyone so close but unaware. Don't know if I'll do it again because there are cameras and I don't want to get kicked out of school but I can at least say that I've done it once
