Well when I was in 5th grade there was this sexy grade 4 teacher, I would (in grade 5) go into the toilets and wank, I would look in the mirrors and play with my dick, the door was always open and the mirrors was by the door, so I wanted while thinking of my 4th grade teacher in a toilet.
Also I have done this twice, I was sent out the to get things from the shop, I would pull a pic of a sexy girl up on my phone and pull my penis out and jerk off in front of someone's house.
