When I was around 12-13 years old I would sometimes masturbate in public and stores like Target and Walmart. They don't have cameras everywhere. I would find an area where nobody was around and begin rubbing my cock and my heart would start racing.

I would get more daring after not seeing anyone for a while and put my hand in my shorts and be fully stroking. I would be hard as a rock and part of me was hoping that someone would walk by and see me, preferably a girl and preferably around my age or younger. I was only ever seen once and it was an old couple. I got away without any problems, never spoke to them.

I have not done this since then, but I have been having a strong urge to do this again and purposely let a girl "catch" me in the act. I have even fantasized about getting myself hard, finding a cute girl, and flashing her my hard cock.
