When I was around 23 (27 now) I hooked up with a guy two or three times in a discrete, tucked away restroom in uptown Charlotte. The guy was about 43 or so and muscular/average build with really pretty blond hair and blue eyes. I messaged him when I was leaving for my break and we met in the large stall and he sucked me off for a few minutes until I came in his mouth. Right after I came I had him leave before me and he walked out. Right as I was washing my hands a security guard walked in; I’m not sure if someone told him we were in there or if he was just coming in to go to the bathroom, but it was really fortunate timing.
In the same restroom I hooked up with him 1 or 2 more times over the next few weeks. I also met a dude in there on my lunch break who watched me piss in the urinal from the neighboring stall; after work, I met him in a below-ground parking garage and he sucked me off in his truck, then drove me to my car a few blocks away.
I also met a third dude in there who watched me cum in the urinal and gave me a hand to help get me off. That night he came to my apartment and sucked my dick in my kitchen.
It was a really greatly located bathroom that was kept clean with marble floors lol. It was tucked behind 2 different service doors, but was still open to the public. After a while, the only people I saw in there were business folks on lunch break that had excessively prying eyes haha, I think that it became known as an easy-access, discrete place to see some dick. I live in Colorado now, way less fun here and not sure if that bathroom is still accessible to the public, but I definitely had some fun in there
