Had one experience of watching my wife and her friend in public a few months back near the Florida Keys at a tie off spot where people congregate on their boats. The day went from mild to wild as they both went from bathing suits, to flashing, and eventually to full nude. Anchored down and not an hour later they both were on beautiful 30’ Everglades (yes I’m a boat nerd) with 4 black men. Before long there were a dozen or so boats watching her get passed around. Funny because before leaving our boat she grabbed my large floppy hat and put it on saying everyone was going to have their phones out which they did. Livened up the atmosphere even more as the bathing suit tops started coming off all around.
