Masterbating In Class

I am 19. I am a virgin. Not by choice. I grew up in a very strict very religious house. I was forced to homeschool till high. Then went to an all male private religious school. The school was strict random room check, computer history checks, if you got caught you would be punished. Etra chores , lose phone call privileges, other tedious tasks designed to break your will. I did my best not to get in trouble. After graduation I decided to leave. I live in a small town now. I worked 2 jobs and did Uber eats and stuff. It took a year but by 19 I had a decent car and a small studio apartment. At one of my jobs the owner is an art teacher at the local community college. He helped me apply for grants and stuff so I started school. I've been looking for a girlfriend but have had no luck. I recently quit my other job so now I work at the art supply store , door dash, Uber eats, go to school. I stay busy. In my science class I sit next to this sexy girl. She is about 5'6, she is chubby but not fat, she plays basketball, volleyball, soccer, so she is thick but toned, every time she walks in I get so excited. The way the classroom is set up the granite counter top sits against the wall and runs all the way along the wall . Half way a half wall is set up with granite counter tops. So it adds more space fore students .I sit in the corner she sits next to me we were busy watching a presentation so the light was dim and everyone was looking forward. That day. She had walked into class she was wearing her hair in pig tails. A red and white checkered tube top. She had on a short denim skirt and tan corked wedge heel. I couldn't keep my eyes off her. Her skin looked so soft. The way her skirt was riding up and she had to adjust it. The way her legs looked long in the wedges. Before long I was hard as a rock. I was adjusting my bulge because my pants were a little tight. It turned into me rubbing my cock through my pants. I wished I could have just pulled it out and cum fast but I had to make sure no one was watching and I was slowly stroking myself it took a lot longer to cum then usual. It took almost half an hour of rubbing and stroking through my pants before I cum. I left with a big wet spot on my pants. This was a couple days ago so I have class tomorrow.

I feel ashamed that I couldn't control myself.
