Didn't really see anything but I was sitting in my car earlier near a popular night spot in town with my windows cracked open when a dark haired girl and her boyfriend appeared. I heard her say "Wait here a minute and don't look!" she then disappeared into an tarmacked driveway out of sight and I heard a huge splattering. Obviously he had the odd peek round the corner followed by shouts from her!
When she had finished I caught a glimpse of her pulling her white knickers and black leggings up and adjusting before walking out. They then walked past my car back to the main road.
I then heard her friend say she needed to go too, she then led her blonde friend to the same place, I caught a glimpse of her ass as she lifted her short black dress to pull her knickers down, then she disappeared to the same spot when a very similar loud splattering was heard!
Unfortunately there had been a lot of rain so puddle spotting would have been pointless but a very arousing experience, more actually than I have experienced seeing girls pee in the shadows! Never heard it live outside like that before
My wife on the toilet but that's different
