Jerked Off During Class

So this is my first time writing a story. But I told it to someone the other day and forgot how hot I remember it being. I was in high school and still figuring out masturbating. I remember hearing about this one kid who always masturbated in class by cutting a hole in his pocket. I remembered I had a pair of pants that had a pretty significant tear in the pocket so I thought one day I would try the same. I was in the front row in science class. The desks were really just big tables and multiple students sat at one table. But everyone was paying attention the teacher and I could position myself where it wasnt obvious. So i reached in my pants and started jacking off. I went very slow so not to make it too obvious but it still turned me on so much to know there were people beside me who had no idea. I started going faster and faster. And I felt myself about to cum. I straightened my legs as I felt my cock start pulsing and shooting cum all in my underwear. I shoot big loads so I was so happy that these pair of pants were black. Because it soaked through and the front of my pants were soaked and sticky in cum. It's not a long story but I found it hot.
