My wife has not been topless or naked yet in front of our friends.
Not that the guys would object, but their ladies are not really open for that.
So not to cause any issue ... she keeps her bikini on while on holiday.
But I do remember my 1st real longtime gf.
I was 22 at the time, she just turned 19 and it was her 1st year as a member of staff of a girl scouting group.
When they went on summer camp, she asked me to join to help out with some of the heavier lifting and cooking.
There was 1 other guy, who was about 35 at the time. We knew him for a long time already, and still see both him and my ex-gf from time to time.
On the camping place, there were no indoor showers. Washing up was done in the woods where there were some water taps and some washing bowls on a table. Us 2 guys were always the 1st to wash up in the morning and the last in the evening ... so when the girls went to wash up, we were not nearby.
Till one evening, both us guys and my gf were out late to prepare a game for the next morning.
When we got back, everybody was already washed and most of the girls were already sleeping.
Only the staff was still awake and talking in the main tent.
So on returning we went to fetch our washing gear.
Our friend said, you 2 just go ahead, I'll wash up afterwards.
But to my surprise, my gf said "just come and join us ... it's already dark, so if you 2 stand on 1 side of the washing area and I on the other end, we will be fine and still be able to talk. Well if she was OK with that, who were we to disagree.
When arriving at the washing area, us boys kept at 1 side and my gf stood at the other end.
There was about 5 to 6 meters (less than 20 feet) in between us, but there was a full moon out.
When taking off her shirt and skirt, my gf stood naked at the other side.
Apparenty, she already left her undies and bra in her tent when fetching her towel and nighty.
Her pussy was pretty much hidden by the table and bowls, but due to the light of the moon, her D-cup was clearly visible from where we were standing.
And although I loved seeing her exposed to the other guy like that, I immediately told her that we could see her naked body. Without covering up, she said well I'm almost done, no use covering up now. So she continued washing up and changing her clothes while allowing us a full view of her breasts.
After we were done, she came up to us and asked us "did you enjoy the view, you naughty boys"?
We could only knod to confirm. OK she said to the other guy, in that case, please turn around for a minute, so my bf can rub my back with aftersun.
So both of them turned round and my gf took off her top again so I could rub her back (and yes my hands did slip to her breasts, just for a second
). When I was done, before she had put her top back on, she said to the other guy ... you can turn round now. As he did, she also turned round, still without her top on ... and stood topless in front of him saying ... since you already had a good look, why not a good closeup ... just don't tell the others ... she stood there for a second or 2 and then slowly lifted her arms (pushing out her D-cup) and put her top back on.
After arriving at her tent (the other guy had joined the other staff), I asked her "what was that all about"?
Well she said, you always like exposing me. So ever since I went topless and naked during our holiday in Greece last year, I kinda seem to like it ... so tonight I have fullfilled both our fantasies.
That was not the last time she went topless/naked in public, but it was the 1st and last time any of my gf ever went topless in front of a friend.
