I pretty terrible thing happened to be when I was in sixth grade. i'll try not to get too graphic. I was on a field trip was a two week summer camp type thing my school did. I have always been a very shy person, and I hated using public restrooms whenever possible. Of course I would use it just when nobody else was around. A day before we took the bus back I got a upset stomach. I figured I could hold it in since the bathroom was really crowded with us being about to leave. It would normally have been ~2 hours to get back to the school. There was a accident so we got held up a couple hours. I couldn't hold it any longer, and let it go in a bus filled with my friends, and classmates. I was wearing shorts so it wasn't discreet at all.
The teachers dealt with the incident very professionally. I have never had a chance to properly thank them. Someone provided me with stuff to clean my self, and some new clothes since all my stuff was packed. I also got a private ride home in a teachers suv rather than the bus. Like one would expect of a group of 6th graders they weren't understanding at all. This led to many emotional scars. Wasn't a happy period of my life. I didn't really have anyone to vent to, and I became kind of a outcast. My group of friends all started avoiding me after this incident. I lived in a small city so this continued throughout high school.
I hit puberty in 7th grade and this is when I started to learn of a few kinks that i had developed. Initially it was more of watersports type deal. I liked seeing women in being desperate to use the restroom. When in 8th grade a transfer student came in wearing a pacifier (around her neck) and childish clothes.
