Girls or guys embarassed or nude in beaches or water parks

[Executionus]

As a kid I saw a ton of things at the giant outdoor swimming pool in my city (sharking was a trend, among other things), but the only beach-type thing I ever saw was seeing an attractive adult woman in her late 20s that my family knew while she was sunbathing topless when I was 9ish.

She and her boyfriend were supposed to be watching me and my little brother at the time but the boyfriend was as dumb as a bag of rocks so he kinda screwed up the whole "keep the boys away from where I'm gonna be laying down with my tits out" plan completely. And the woman herself was as dumb as a bag of rocks that was just slightly smarter than the OTHER bag of rocks, so naturally she fell asleep face-up while topless at a public lake area while babysitting two preteen boys and her own two preteen children. She was woken up during the commotion of her discovery by all five of the other characters in this scenario and then did a pretty entertaining freak out trying to cover up 30 seconds after we'd already seen and memorized everything.

When I was 16 & on the school track team I got invited to a pool party in a teammate's backyard. Had on the usual board shorts type of swimsuit with a drawstring. Their pool featured a diving board. If I loosened the drawstring just a little bit, and then did a forward dive into the pool, my swimsuit tended to go down to my knees as I hit the water. I would quickly pull it back up before surfacing. As the afternoon wore on, I got bolder and started doing running dives off the board which caused the swimsuit to fall down below my knees. Then I would surface before pulling it up.

Didn't think anyone was noticing until I overheard my buddy David whisper to two of the girls, "Just watch Nick do another dive if you want to see his dick."

And did they?

Unfortunately, after overhearing that whispered conversation, I lost my nerve & didn't dive again. My buddy David told me the next day that several of the girls there had been aware of my swimsuit falling down during the dives. Of course, the chlorinated water would have partially obscured their view of my penis. David said that even the host's mother had been glancing over during my various dives, but never said anything.

How old was she?

She can't have been older than 10 but she was quite tall for her age and had a really pretty face.

I was knocked over in the sea by a wave and my swimming shorts fell down a few people definitely saw.

Lots of times, but most spectacularly at a water park when I was 18. Friends dared me to go down the biggest slide face first on my tummy. It threw me pretty high in the air, but I managed a clean re-entry.

I walked forward into waist deep water, raised my arms in the air, and yelled 'Nailed it!'. A pretty plump lady tapped me on the shoulder, and said 'You might need these,' and handed me my trunks, which had come completely off. She patted my bottom, and said 'Cute butt.'

My second oldest sister managed to lose both halves of her bikini once. The water wasn't even that rough so I don't even know how it happened. Luckily the water was murky so she was able to hide her nudity. I saw her kind of away from everyone and went to see what was wrong, but when I got close she held out her hand and told me to stop. She told me what had happened and asked me to go get mom. Fortunately for her they were able to recover both pieces. I'll never forget her face, though. I don't think I have ever seen such genuine panic mixed with embarrassment.

This one is a classic
