[The Salty Deer]

Actually I have two people to mention, but they were both 'only' topless and not nude. I hope that's OK.

First was about 30 years ago. I was a student in university and was chosen to attend an international student conference in Denmark. The conference was all paid for by the Danish Foreign Ministry and hosted in Helsingør. All participants stayed at a Højskole which is like a college of sorts and that's where the meetings were held. It was late June, school was not in session and we had the run of the place.
The conference was international relations themed and there were students representing the various countries involved. The were also some local students, Astrid being the one who stood out.
Astrid must have been about 20 years old (approximately same age as myself at the time) and she was a cute and bubbly Danish girl. Real nice looking and even nicer personality, always fun to be around and have in the group.
I came from a conservative background (and a conservative country) and my experience with girls was extremely limited so it's fair to say I was attracted to Astrid but didn't do anything about it. Didn't know how to approach.
Well, Astrid had no such problems. She was open and friendly with everyone, myself included.
The conference lasted approximately two weeks and for most of the time the weather was horrendous. Real Danish summer with grey skies, rain, low-ish temperatures. As someone from a much warmer climate I can say I was not happy to be spending my summer in such conditions.
But all that was about to change.
The weekend in the middle of the conference included some time off which everyone could use as they saw fit. Some went to Copenhagen, some to the Louisiana Museum, some even crossed by ferry to Sweden to visit Helsingborg. And finally the weather took a slight turn for the better with sunny skies and slightly warmer temperatures.
I was unsure what to do and whom to join when I heard Astrid speaking to one of the other Danes and mentioning a beach. Now I love the beach, always have, and I enjoy nothing more than spending time there in the summer. But in Denmark? With not very warm days and not much sun? I was hesitant but decided to throw caution to the wind and I asked Astrid if I could join her at the beach.
She hesitated only slightly, gave her trademark smile and said sure. She warned me though that we'd be biking there and back. No problem for me.
Everyone left for their various activities and I found myself alone with Astrid (the other Danish student having gone with one of the other groups), pulling a couple of bikes from the shed. Astrid ran to the kitchen and got some picnic food (bread, cheese, hard boiled eggs) and we set off.
Denmark is not very hilly and the ride was not difficult. After close to an hour of cycling we reached the designated beach, left the bikes, and made our way down to the water.
The first thing I noticed was that I was surrounded by naked and semi-naked people on the beach. It seemed at first glance as if nobody was fully covered. It was shocking for me as I was not used to this kind of beach and Astrid had not seen the need to warn me in advance. She looked over at me and could clearly make out my shock, and she just smiled reassuringly.
We choose a spot and laid out our towels. I sat down on mine and heard her next to me:
"I wasn't going to take any of the conference participants with me to the beach, didn't want to make it uncomfortable for the second week of the conference, but since it's only you I figured it's OK. I know you'll be mature about it and not make us uncomfortable". And with that she pulled off her shirt and bikini top.
So I got to spend the rest of the day frolicking in the water with a totally unabashed and topless Astrid, surrounded by semi and fully nude Danes. It was a remarkable day, still etched in my memory some 30 years later.
For anyone wondering, there was no sexual contact between us whatsoever. We may have touched slightly here and there as we played in the water but nothing even remotely resembling a grope or a squeeze.

The second was my wife's sister but there seem to be so many of those stories already posted that I guess mine won't add too much.
