There was a public restroom in a shopping mall I used to go to regularly. There were five urinals in a row, with no dividers between them. It became a popular place for guys to stroke their hard cocks and show off. Sometimes there would be five of us in a row--not saying a word, just enjoying being watched and taking a peek at the other guys. Every now and then someone would lose it and cum in the urinal. Just some harmless exhibitionism/voyeurism. They have since put up dividers and spoiled the fun.
