ugh it did

Well I’m sure it felt absolutely amazing. 

She just laughed it off. I've pissed in front of her many times.

Haha love it. How did your sister react?

Ohh, one time, I was in the car with my sister and she was driving, were stuck in a highway with super heavy traffic and I needed to piss soooo bad! With nothing left to do I told her that I was going to go behind a few trees that were to the side of the highway and I ran over there, I went behind the first tree I saw and squatted to let out a beam of piss that sounded like a fire hydrant haha. I'm pretty sure that the cars to the side could see what I was doing but I didn't care at all. I also rubbed my pussy a little before going back to the car hehe.
