7th grade, in class, staring at a hot teacher one table away. she was looking right at me when i exploded. got light headed from holding my breath and concentrating and about passed out. nobody had a clue. my technique was flawless. well, except for the sticky underwear.
11th grade, in class, staring at whoever, don't remember who she was, but she was cute enough, as confirmed by the mess in my bugle boys.
in some girls nachos when i was drunk and she was in the restroom. guess she didn't notice, because she ate them all.
at many jobs, many times.
in the airplane restroom on a flight to paris.
on a moving train in the restroom somewhere in germany.
