As is true with a majority of Solo Touch users, I have a long, rich history with masturbation. I discovered it from an older friend and have been masturbating steadily ever since.
This happened in science class. I went to a small, Catholic school. Though it was never said, masturbation was looked down upon by the Catholic staff. Our uniform was a white oxford shirt tucked into black or navy slacks. Of course, you were out of uniform if your shirt was untucked.
Anyhow, in science class one day, it was a bit cold, so I had my arms inside the body of my shirt with the sleeves hanging loose. I started moving my right hand down toward my pants. Because the shirt was tucked in, the transition from shirt to pants was very smooth. My hand was met with a distinct bulge in the pants. Very slowly, so nobody not the teacher, my friends, and especially the girls could see any movement in my pants. I slowly moved my cock up and down inside my pants. It was so exciting! It didn't take me very long, only a few minutes to cum.
When I was done, my best friend looked over at me and asked what I was doing!! I don't think he really knew though, I think he meant my arms in my sleeves.
Well, happy jacking (and hopefully jilling)!
