When i was in the 9th grade, i was a very horny boy often not being able to contain my sexual desires at home due to being scared of getting caught. So one day in class during English I asked my teacher if i could use the bathroom. She said yes so i proceeded to make my way over to the boys toilets. As i hadn’t relieved my self in a good couple of months i was already erect just by the thought of jacking off. I walked into a empty stall, luckily no one was in the toilets at the time. So i proceeded to start stroking it with no thought whatsoever. About 2 minutes in i hear the door open someone entered the stall next to me. I got really scared and anxious as i still was just casually stroking it in the middle of the school bathroom. I felt it coming after awhile then my nut shot up and went over the stall next to me followed by a loud scream. I got so scared that i ran out the bathroom straight to class like nothing had ever happened. That was probably the worst day of my life.
