Not necessarily a low key event
 

Your post reminded me of a wedding my girlfriend and I attended when we were young. She was part of the wedding party of her girlfriend's wedding. All the women "standing up" had been given these red, cheaply-made dresses they had to wear. At some point during the reception when we were buzzed, my girlfriend and I decided to head upstairs to our hotel room for a quickie. I don't think we even bothered to take her dress off before we started fucking. As I recall I took her both from behind and missionary. After she orgasmed she always wanted me to come inside of her, so that is what I did. By the time we were finished, her dress was in shambles. She put it back together as best she could with safety pins and we went back down to the reception. People with quizzical faces asked where we had been. I think we said we went out for a walk to get some fresh air, but the condition of my girlfriend's falling-apart-dress spoke volumes. Later when we were sitting at our table eating and toasting to the bride and groom, she told me she could feel cum running down onto the back of her dress. Oh, to be that horny again.

My wife and I are in our mid 30s but she keeps us fairly current with styles. I’m sure most of you have noticed over the last decade the trend in women’s bathing suits showing more and more ass. It used to be seeing a thong at a pool or a beach was a rare treat, now it’s nearly every girl you see. Point being, my wife has transitioned to wearing these. She has a great ass so I love that she’s embraced this. However it was a fairly slow transition. At first she’d only wear them at home at our own pool and just when it was only us two.

A few summers ago we had friends stay with us and my buddy’s girlfriend wore a bikini with a thong bottom so my wife decided to wear hers too. That was a fun weekend to say the least. So it became normal that if our guests were showing off some booty so was my wife. And every time we were on vacation she wore them too. Countless strangers have had a glimpse of my wife’s round buttcheeks.

Eventually she exclusively wore thongs with one exception: when her cousin and her husband came to visit. Her cousin is slightly older and very reserved. She’s a dentist in her hometown and she and her husband are just sort of square. Their visits are usually the only ones we get throughout the year I don’t look forward to because they’re so dull. This summer they showed up and we decided to have a pool day. It was in the low 100’s so what else to do? I was already at the pool when my wife’s cousin and her husband walked out. She was in a one piece suit with shorts pulled over her bottom half. She’s actually quite pretty but doesn’t show anything off. A few minutes later my wife joined us all and removed her towel to reveal she was wearing one of her regular bikinis. Thong and all. I caught her cousins husband multiple times taking a peek when she would get up to do anything. She wears these suits all the time so it seems normal to me now but in front of these guests this was the first time.

After the pool, in our room changing, I asked why she did it. “I only have suits like this now. If seeing my butt is going to bother them, they don’t have to visit” I sorta laughed and said “well it certainly didn’t seem to bother (cousin’s husband)”. She smirked and walked into the bathroom. Her cousin got a bit sunburned that day and declined any time in the pool thereafter, but we can’t help but think she has a hangup about her husband seeing another woman’s butt. To me it’s a bit of a thrill and also funny that they got more of a view than they bargained for.

sis in law
 

A few years ago my oldest sis in law was coming over one morning,I decided to vacuum the pool out back in the nude,my 2 other sis in laws have seen me many times and skinny dipped with me but never Carol she is a bit older,I heard her car drive in and she got out,it was exciting for me and i was half erect thinking about it the whole time and I was facing the house,after a while I heard her car door shut and she drove away never said hi or by to me,right then my wife walked out in a puff and said did you have to be naked out here,Carol was watching you out the widow and said you were nude,I said so what your always naked infront of yourbrother in laws and friends,she said thats different,I was so happy,even years later I gave Carol a show.

Just came back from a holiday in the Dordogne (France).
SIL has a holiday house there and our 2 families went there for a week. Wife was in our bedroom undressing to go for a nude swim when her mother and stephdad arrived with their mobile home as a surprise. So my wife did put on her bikini.
I already knew she would NEVER go nude in front if her stephdad (or stephbrother for that matter), but I did ask her "are you sure you want to put on the bikini? I know how much you looked forward to swimming in the nude. You still can go nude or topless". She did hesitate for a moment, but said "Nope, he's not getting to see my pussy or tits".

Nude Spa
 

Have been gearing up for a trip to Germany for a number of months with my wife and I have been trying to get her to visit a nude spa while we are there. I love the idea of her being naked in public in front of people. She’s in her mid thirties with a nice body and boobs that bounce when she’s naked.

I suggested it a few months back and received a very coy, non committal response that she was just looking forward to being on holiday…. She acts shy about her body but I have always suspected she is happier to show off that she lets on.

I brought the nude spa up a few times with mixed reactions since but never a no. I just love the idea of being in a big, mixed changing room with her and her undressing in front of everyone and showing them her boobs and pussy.

We have been in scenarios where people could see her boobs and pussy through her swim suit and my wife just didn’t care at the time. Let them see them, she’d say but then other times would pretend to be bashful.

We went skinny dipping on a public beach during the summer and really enjoyed that. She told me a few weeks ago that she was unsure however about being naked in front of lots of people but this weekend agreed when I suggested she could put on and take off her robe whenever she wanted….

My suspicion though is that she will love being naked and once her robe comes off, it will stay off for the entire day. And while I’m really looking forward to seeing her makes while surrounded by lots of people, I think I will also improve her confidence about her body (and she will then in turn show it off even more in future!!)

We are now planning a trip to a large spa in Berlin and then I’m hoping we can also visit the hotel spa afterwards when my wife enjoys the large spa. I love the idea of sitting down to dinner at night and lots of people there having seen my wife naked during the day at the spa…….

I'm not sure if this is low key or not, but the girl involved certainly was.

I used to work in the sporting industry, it was my own home-based business, and sometimes it involved fitting people into wetsuits.

There was an occasion when a couple came to my house to purchase a wetsuit for the wife. I got out her suit, and led her to our ensuite bathroom to get changed. As I was explaining the intricacies of the product to her, she started stripping off. At that point, I said 'I better leave!", and she replied that she didn't care if I stayed. She stripped off everything except her knickers, tried on the suit, took it back off & got dressed. I walked back out with her, she bought the wetsuit, and they left.

Her husband had stayed out in the lounge with my business partner the whole time. He knew she was trying on the wetsuit, but obviously didn't care. It was weird, but fun.

I worked as a deck hand on a dive boat one summer. If someone didn't have a wetsuit, we had some to rent, ours were one piece that you pulled over your head. If a woman wore a 2 piece swimsuit, when she pulled it off over her head, her top was coming off with it 100% of the time. That was a glorious summer.

One of the fun aspects of scuba!

sister in Law
 

I was leaving my future sis in laws house one night and seen a red light in the cellar window as I went by I looked in to see why it was red in the cellar,it was a red short over the lamp and my future sis in law was giving her boyfriend a blowjob in the cellar right under the window,so I watched,I got thinking about it years later and thought that was do hot.

I have heard other working in those situations say exactly the same thing!

My wife and her mom went on one of these excursions and saw it happen to a few women for themselves in person. Too bad I wasn't with them!
