I often have a wank in a public toilet, well I did before this covid business. I used to leave the door unbolted to increase the risk of being caught.
One of my more adventurous friends will unbutton her jeans and then unzip before masturbating while driving home late at night. She's called me once or twice to tease me but I tell her to pull over or at least hang up and finish. She never invites me to watch but it's fun to hear her breathy voice as she's strumming herself. I've jerked off in public before being purposefully watched or in a car with someone. That's about it although there may be more.
Just two days ago I stopped for gas at a convenience store for gas. I needed to use the bathroom, I enter the stall to take a dump. While taking a dump I get an erection so I just rubbed one out right there on the toilet.
I thought it was just me for whenever I take a dump in a public toilet or outside somewhere, I always get an erection. Which of course needs to relieved.
I've done it on a busy city intersection not a quicky either. Took my turn crossed all the streets and stood in each corner.
