Not really "naughty," but certainly uncomfortable.
At 15, I was talked into going to one of those "sensation spas" with different kinds of pools and showers, and you go around each one in a certain order - cold showers while talking over pebbles, ice-cold pool, jakuzi, that sort of thing.
Anyway, I'd been in the jakuzi tub for a while when I realised I'd ended up with a No Reason Boner and I was not risking getting out while pitching a tent, so I attempted to try and get rid of it the only way a horny teenager knows how - good old righty, ya never let me down.
...
Then a young couple in their 20's got in to the tub opposite me and I almost (metaphorically) shit myself.
My only saving grace was the fact the bubble jets hadn't been turned off at that point, though I have my doubts they were entirely oblivious to what I was doing - I managed to rub one out before getting out if there, so go me, I guess?
Definitely the most awkward wank I've ever had, even if it was just a one off, but at least no one caught me and gave me a thrashing about it... they needed a salt-water pool anyway in that place. XD
