Here's one that works: Wear jeans with a tshirt and hoodie and scope out an older guy in a department store or somewhere he's relatively alone. Go up to him and ask if he knows where the bathroom is. If he says yes, as he's giving you directions, act like you lost control and pee right in front of him.
Make sure you can cry as soon as you start wetting yourself and see if you can get him to get you some clothes. It'll work better if the guy has some money, not some poor guy.
If it don't work, tie the hoodie around you and leave. If it does, you just got some new pants!
I've always wanted a woman to pee on my erect cock. Want to try that?
in the shower
I'm a female.. when i happen to be home by myself i typically am naked or in my undies. which is very convenient when you need to pee. If i am busy doing something and don't want to take time away from the task at hand I look for a container to pee in. one day i was folding the laundry and really needed to pee, i wanted to finish folding the pile but was doing the pee pee dance and didn't think i could hold it. To my relief there was a vase on the dresser behind me. i grabbed the vase, positioned it as so and peed. It felt so good and liberating to just pee. I continued on with my task and washed out the vase later.
another time just for fun, i needed to pee real bad but didn't want to use the toilet. Next to me was the Sunday paper. I spread the paper on the floor and stood over it to pee. It felt so dirty and liberating to just stand in my kitchen and piss on the floor like a dog.
I've pissed on the carpet... It's amazing.
