Classroom Fun

One day we had a substitute teacher for one of our classes so I took the back seat with no one around me. She decided to show a movie in class and so the lights went out and I got horny in the dark classroom. I started rubbing my dick thru my pants. A couple of students looked back but couldn’t see what I was doing due to the darkness. The teacher was quite attractive and got my mind  fantasizing. My dick was quite hard in my pants and I was enjoying the rubbing thru my pants. Since I was alone in the back and it was dark I unzipped and pulled my dick out out of my pants under my desk.  I was so turned on by taking the risk and discreetly slowly stroked it. The teacher was sitting in a side chair watching the movie plus it was so dark no one knew what I was doing. It felt so good and I knew I wasn’t gonna be able to stop. I grabbed my hoodie and put it over my lap and stroked a huge load into my hoodie trying to muffle any moan or grunt I usually made when shooting a load. It was such an amazing thrill to do that but I needed to clean up a bit and left for the bathroom holding my hoodie in front of me to hide the boner. It was a memorable jerk session that I will never forget.
