I've wet my pants in public many times. I'd be sitting on a public couch and just let it flow as people walked by, not usually noticing the growing dark spot on my jeans. Then I'd relax a little more as i walked home and a puddle would start to form at my feet, soaking my sneakers. Sometimes I'd be in light gray sweatpants and it was in the mens room. Sometimes the ladies room. I'm not above reaching into a public toilet to turn myself on. I like everything dirty.  I wear the same gym clothes every time i work out. I also use them to blow my nose. 

I threw my underwear into an unflushed public toilet once. I dipped my shirt in as well. It wasn't just alittle unflushed either, it was like, a whole day of use unflushed, and it smelled like it. I reached in and pulled out my undies and slid them on. Cold man juice ran down my legs. I slid my jeans on over them, quickly soaking them too. I pulled my piss soaked shirt back over my head and walked out of the mens room, going home. 

I reeeked of urine. I went home passing my neighbor on the way. I'm pretty sure he knew i smelled like a toilet. I undressed and put my boxers in a plastic bag. These would ripen over the next few days.
