Hiding in the girls room
I hate to admit this, but I hid myself in a womens rest room a few years back to listen to them pee! What a turn on this was for me ... I could imagine them sitting on the toilet (in the stall next to the one I was hiding in) ... pulling their panties down and letting go a stream ... then I imagined them wiping their pussy with paper and finally pulling up their panties ... never got caught, but had a close encounter once ... nevertheless it was a great experience
