In public around people

Yeah, the first time was back in middle school. I was I believe in the 8th grade at the time. What happened was I'd be in the back of the bus and I'd save some downloaded porn videos to my PSVita (I wasn't permitted by my parents to have a smart phone until high school) and basically I'd use them to jerk off in the back of the bus. It made it even more arousing to know that there were people on the bus in front of me and that if anyone came back there they'd see me jerking off with my dick out. There were also cameras on the bus but fortunately nobody checked them unless someone did something to get in trouble so that also turned me on quite a bit knowing there was undeniable evidence out there that nobody would ever see. (My mom was on the school board I discovered the footage is deleted after x amount of days.) The thing is back then we had a designated student who was typically an 8th grader who's job was to occasionally patrol the bus and check to make sure everyone had their seatbelts on and they normally skipped the back of the bus. Unfortunately for me the bus monitor for that year and particular bus ended up catching me one day after doing her patrol late. I was so fucking lucky though because she was so cool about it. She'd end up using every excuse she could to go back there and interrupt me back then. She'd offer me candy on holidays that the bus driver was handing out knowing full well what I was doing back there. A few times she even took the adjacent seat as I did it. The fact she was in my grade and lived close by was a bit embarrassing though but she was kind enough to not report me or (at least to my knowledge) not tell anyone in class.

Sometimes at the worst of times. A man needs to scratch his itchy balls.

Yes but not all the time
