Nude or topless in front of b/f's mate

No pics here, only a story.
Happened when I was about 20yo.
Group of friends went on a long weekend away in the mountains.
Doing some hiking and in the evenings have some fun, drinks and playing board games.
There were 8 of us : 3 couples, and single girl and me (single male).
We had 2 rented 2 cabins. My best friend and his gf, the single girl and myself shared 1 cabin, the other 2 couples shared the other cabin. The layout of the cabin was pretty basic.
But there was only 1 big bedroom in which 4 single beds were placed. The cabin did however included a sauna.

So when arriving on friday evening, we all had a meal together and afterwards went to the cabins.
After some talking and a nightcap, the 4 of us were preparing for bed.
My friend and his gf were using the bathroom first.
To my surprise (and surprise of the other single girl), my friend walked out of the bathroom naked, followed by his naked girlfriend.
I remember his girlfriend giving me a wink and saying something like "we always sleep naked ... and besides, when we use the sauna tomorrow after our hike, we will all be naked anyway".
The girlfriend was a small slim girl, with a nice ass, smooth pussy and C or D cup (rather big compared to the rest of her body). Kinda a Melissa Rouch kinda figure.

Well personally I had brought a swimtrunk to wear in the sauna, cause I totally was not expecting this.
Next the other girl used the bathroom. She came back out topless, only wearing some small undies.
She was a bit taller, had a nice ass (as far as I could see) and was supporting a B/C cup with puffy nipples.
Then my turn. I had never been "casually" naked in front of others, only in front of a few ex-gf, but I also decided to sleep naked. Although I got quit nervous of getting hard in front of the others.

The next morning, my friend got up and started making coffee while his gf started setting the table ... naked.
So I also went to help them without getting dressed.
There we were : 2 naked guys, 1 naked girl and a topless girl ... having breakfast.

The 8 of us spent most part of the day hiking ... and while getting back to the cabin, everybodies legs and feet were hurting.
After getting back we had about 2 hours before diner, so everybody retreated to his/her cabin to get a shower and some rest.
When getting to our cabin, the small sauna was turned on while we took turns in the shower getting rid of all dirt and sweat.
The girls went first and after about 20 minutes, they both came out of the bathroom wearing a towel.
After my friend and I got out of the shower too, the sauna was about ready so the 4 of us went in.
This time we all were naked and I could enjoy viewing the other girls smooth pussy too.

We had some small talk in the sauna and at 1 point the single girl said:
"I'm so glad I got to stay in a cabin with you guys so we can have a naked sauna session. One of the fun things during a sauna session is feeling the drups of sweat running down my breast and the rest of my body."
Apparently during our hike, she had spoken with the ladies of our friends who stayed in the other cabin.
Seemed like they were the insecure/jealous type. They all had slept wearing pj's and they were planning to wear bathing suits when using the sauna.

Although nothing sexual happened and casual nudity quickly becomes "normal", it had been an eye opening experience for me.
Luckily I found a lovely wife who is not a prude and has no issues with public nudity.
So still today we have fun in casual nudity situations ... both at home and in public.
