Family members see the wife/girlfriend
 

I'm curious, how many of you have shown you wife/girlfriend to your brothers or other family members.
Can be in pictures or in real life.
Since seeing my sisters picture on her computer of her boobs, I have been wondering about this.
I actually ended up showing my brother the pic. We sat there and talked about it for a couple seconds. Then the talk evolved to our wives boobs.
I chickened out, but it was a great chance for me to do it.
My father really likes my wife too. I have to imagine it would be quite wrong, but wild to show my dad my wifes tits.
so, have you done it? Do you keep the pix?

Showed to my brother
 

I showed photos and videos(several of her in action) of my wife to my brother. He really loved the vids of her giving head.

I don't know which one of us enjoyed it more, him or me. We had copies of his favorite pics of her made and he kept them. He told me he had a few of her posted up in his locker at work and several of his coworkers got a good clance at her.

It was a huge turn-on for me to watch him looking at her and listening to his comments. It was an even greater thrill when we were all in the same room together and he was looking at or sitting close to her. All I could think abot was she had no idea he knows exactly what she looks like under her clothes.

We often talked about him getting a turn with her in bed but unfortunately the opportunity never developed. I would have loved it if he could have pumped a load deep into her.;)

Here's a photo of what she looked like back then:

My wife is nursing again and she and her sister have never seen each other in any state of undress. Even though they are sisters, they are prudes around each other like that. Well, yesterday I talked my wife into nursing the baby in front of her sister without covering up. My wife's own sister stared at her breasts like a 15 year old boy. It made me so wild. My wife didn't think anything of it at first, but later that night we talked about it and it kinda turned her on a bit that someone was staring, regardless of who it was that was staring. My wife's breasts and nipples look the same while she is nursing as they do when she isn't, so now her sister will always know what they look like. She has pretty unusual nipples, so I am sure her sister will tell her husband all about them.

About a year ago, my wife was wearing a skirt and I saw my dad staring right up her skirt at her yellow underwear. I didn't tell her that he could see. He got 20 minutes to see and I didn't say anything. I felt kinda weird about it later, though, because my dad is a gross perv in the worst way.

Harry, She deserves her own thread. Very hot lady. Am I the only one who would love to see her vids?

My brother in law saw my gf totaly naked.. in real life and on pic's/vid's.

I went out for some errands and forgot to turn of my pc, and my brother in law known we into taking dirty pic's and stuff, from conversations on msn and so.

So the moment i closed the front door he was behind my pc and went looking for pic's.. to bad for him i forgotten something and headed back in 3mins later.. i found him there looking true our "hidden" folder of dirty pic's of my gf ...with a boner :D

It kinda started there, my gf is really into showing here self and seeing others likeing it (it runs in the familie).
After founding him like that i told here about it and it got here hot, knowing some1 seen here like that and got turned on by it. She started flashing him the boobs in silly accidents way.. like having no bra on and bending real deep to serve him a drink or food with a really short top on and let him walk into the bathroom while she having a bath saying i dunno wtf she doing upstairs go have a look :P

One thing led to the other..
The score atm is a some tittie play,sucking here nips, jerking him of and some fingering.

But the awsome thing is... it runs in the familie so i get my fun with here sister.... and we did a bit more then them already :D

first 2 pic's if my gf so thats what he playing with and the other 2 pic's are what i play with, we aint picture perfect.. we we enjoy it.. and no.. brother in law doesnt know iam doing his wife.. he's the only 1 not knowing it all ^^

you not alone... :D

This morning my family got to see my girlfriend's tits. We overslept because of a party the night before, and so we missed the breakfast. As our "bed" is in the living room of my parents, we wanted to watch the Formula1 race this morning on their flat screen. I got up and managed to get a shower, then I brought her the breakfast and we started watching TV. Soon my father, then my brother-in-law came in to join us watching. My girlfriend stayed in bed.
If you've read my other stories you'd know that my girlfriend isn't shy and likes going topless on the beach, for example, but my family hadn't seen her naked, so far.
While we were watching, I noticed that the linen of the bed had fallen down a little and her nipple was on display. I smiled and gestured to her that she'd pull it back up. She did, but seemed to forget about it a few seconds later. When she grabbed her coffee the next time, both of her small but perky tits were on display for us. She didn't seem to mind, as she must have noticed this. She didn't pull it up again but left them out. My father and brother-in-law got an eyeful of her titties. I noticed them watching from time to time.
After the end of the race they both left the room for a cigarette. I asked her if she hadn't noticed and she said she wouldn't mind, as it's in the family. I kissed and caressed her tits and told her how much I liked when she did things like that.
After her coffee, she then stood up, put the bedcloth away and went into the bathroom topless with only a g-string on. She smiled at me we she got out, because she really knew that she would have to pass the kitchen, where all the others were sitting and could be watching her through the open door... She stopped there, looked in and said: "I could have another coffee after the shower". Then she went to the bathroom. I had a big grin on my face.

I think your girlfriend would go down a storm on here, maybe you should ask her if its ok to post her?;)

I will.

I showed her my posts and she really got a blast.
She's quite turned on but doesn't want her face to be shown on the internet...

big cheer for the blur tool in most photo programs then :D
or crop it out the pic.. my gf also doesnt like here face on the net when she doesnt have clothes on :)

.
 

I can understand that mate. Get her to pose with her face hidden, it looks far better than bluring the pic. You never know she might get into it.. ;)

thats a really hot storry i cant wait to make my gf my wife shes really hot

My experience is a little different than the ones posted here. My wife, April, was my older brothers girl friend for almost 3 years. He was the first to have sex with her and he is almost 2 years older than me. I was in love with April from the time we were in the 3rd grade together, but when we got older she fell for my brother. I know they had sex alot because one time on a camping trip our family went on and he came with us he told me that was the first day he had not had sex with her in over 3 months. I remember thinking WOW!!

I never tried to cheat with her while she was with my brother and I had plenty of girl friends before they split up. It took me over a month to convince her to date the brother of the guy who broke her heart, even if we were almost best friends.

We have been together for a long time and married over 20 years. The past is the past of course though it did cause a little tension between him and I at first because he had cheated on her, causing the break up. He is happily married to a beautiful woman he met while working in south Texas, but I still see him look at April at times during the family get togethers and holidays. I know he still remembers and remembers well. It is not something that turns me on, but I live with it. It is part of my life and has been for a long time. I don't begrudge either of them for the past either. Sex is sex and doesn't have to change people or create issues unless you let it or want to let it.

Great thread! Just wanted to add my two cents worth!!

My sister and brother in law
 

The first time my wife and I went to a sauna is about 15 years ago. We decided to try it as my sister told about her visits to a sauna with a lot of enthousiasm. I know my sister still goes to a sauna regularly, sometimes with female friends and sometimes with her husband.
About one year ago my parents took my sister, myself and our families on a short vacation. We all stayed in a house on a resort with a luxurious sauna and many other amenities. My parents offered to babysit so my sister, my brother in law, my wife and I could spend an evening in the sauna. That was the first time we all saw all of each other.

My sister proved to have a full figure and large breasts. Her husband is overweighted, it turned out his genitals were hardly visible. My wife and I on the other hand, are in pretty good shape. I caught my brother in law looking at her small but firm breasts and shaved vagina more than once.

Keeping it in the family
 

I have no siblings, so my only option for this type of thing was my father. It was never (or seldom) my idea. He was not shy about asking.

One night after a rather hot date, my girlfriend and I decided to back to my parents house. She had on a yellow summer dress. I had removed her panty hose at some point during a make-out session in the car. I then used the hose to tie her hands behind her back for the journey home. It was late, and there is seldom anyone in the house awake after 11:00. But on this night, we entered to find my father watching tv in the living room. My girlfriend tried hard not to act surprised or embarrassed. It only took my father a moment to realize that her hands were staying behind her back and asked why. I boldly informed him that her wrists were tied together. He asked to see and she turned around for him. Of course this excited him. But then he asked to have a closer look. he stood and walked to her. examined the panty hose, which were not tight at all. He then turned to face her and in doing so lifted her dress to waist level to examine her hairy bush. He complimented her and then returned to his seat.

A couple of years later, a cousin of mine had come to visit. I had a new girlfriend then. On afternoon after a lot of beer, he accepted the offer to go to the bedroom with my girlfriend. From the hidden camera taper I could see that they each performed oral sex and then finished in the missionary position.

My father having a key to my place, would often slip in when I wasnt home to watch my home movies. this continued through several other girlfriends as well.

the last girlfriend in this story had an incredible body. Tiny breasts with eraser nipples and shaved smooth. I loved taking photos of her. Of course I continued to share these with my father. She was mortified, but eventually accepted the idea. This lead to him eventually fingering and eating her, and that would have resulted in penetration if his viagra had not failed him. poor guy.

The following photos are of the 2nd and last girlfriends mentioned in this story. digital photography was not invented when I was with the first girl from this story. sorry guys.

This is what Daddy saw:

gf/wife showing
 

When with my first wife I showed a couple of photos of her spread to my father one time,in return he showed me a few of my step mother at the time. As for my wife now,I have showed her photos to a nephew of mine a few times and he has shwed me some of his wife.

Oh come on you have to tell us more!! WOW sounds hot!

Over the weekend, my sister's husband was over, and I was showing him how to do simple video editing with some software I use. I was showing him a sample finished DVD and it happened to have a clip on it with my wife breastfeeding. Since it was just my wife and me when the video was taken, she wasn't covering up or being careful for the camera.

I honestly didn't remember that the breastfeeding clip was coming up, so when it started, he said we could skip it, but I said that he already starting seeing it, so we will keep it going to see how I made some cuts. The clip went on for a good 5 minutes or so, with my wife's breasts exposed for almost all of it.

I teased him about his deer-in-headlights stare, but I told him it was no big deal. He went on to tell me that when my sister breastfed, that she wouldn't even let him watch (her own husband!).

So, later when we were hanging out with my wife, I told her that we ran across the clip and she seemed to be hiding that she was upset. Then I told my wife that he wasn't even allowed to watch his own wife nurse, and she said, "too bad I am not nursing now because I would let you watch all the time you poor thing." The funny thing is that she did used to nurse in front of him, but my sister would hit him every time and tell him to turn around or leave.

He ended up staying quite late, so when my wife was about to put on pajamas, I told her to flash him. She said she wouldn't flash him, but she did wear her paper thin pajama top without a bra, which she is very conscious to never to around anyone except me, so at least she did that for him. I told her to flash him next time and she said maybe, depending on the exact context and how she felt.

Showing Family
 

My nephew is 43 and lives in Arkansas, I once sent him a very nice photo of my natural redheaded wifes pussy, it was gapping open after I had fucked her and my cum was dripping from it. There were no face shots or anything else just of her natural red pussy hole. He ask me who's pussy was that, I told him it was just something that a friend sent me of his ex girlfriend. My nephew still doesn't know it is really his step aunts pussy.

Brother's wife
 

My brother was nearing the end of his marriage to his first wife, things were rocky after he discovered she had an affair with one of her coworkers. I went over his place one afternoon and after a few beers he told me the whole story, then he started telling me how he could tell something had changed because their sex life had become 'different'. So after explaining how great it was before the affair I fell into the trap of telling him about our sex life and that I had always thought his wife was very hot. He said he thought the same about mine, and then asked if I had ever done videos or taken pics of her, when I admitted that we often did pics he laughed and asked I wanted to see some of his. We went up to his den and he had a huge collection of her, mostly posed and R-rated but a few hard core and a good number of unaware pics. We then shot over to my house and I went through ours. After his divorce he went through a phase of fucking a lot of different women and surprisingly a lot of them let him take pics, which he always showed me, more or less showing off. I never told my wife that he had seen them, and his current wife has no idea that I get to see her 'private' pictures.

Wife & Brother in Law
 

As you may have noticed from some of my other posts my wife can be a bit carefree at times. My wife's sister is a bit of a dressmaker so when my good lady needs any alterations done then she is only willing to help. Some years ago we were due to go to a function and her outfit needed a few alterations. We headed over to her sisters and I sat and spoke with her husband whilst the girls debated the finer details. I should mention that my brother in law is a bit of a prude and being around semi dressed women gets him flustered. Anyway the four of us are in the room and without warning off comes my wife's jeans and top, standing there in her black bra and pants and on with the outfit. She obviously noticed his discomfort because after pinning the bits that needed altered she remained in her bra and pants. 15 minutes later time to try on the finished article. As she picked up the top she engaged him in conversation causing him to look at her as off came her bra before pulling the top over her head. Well the look on his face was epic and my wife continued talking to him as if this was the norm. On went the trousers, lovely white figure hugging outfit, but my sister in law stupidly said to my wife "did you have to wear black pants it looks ridiculous". I said to myself NO as I just new what was going to happen next. Still talking away to my brother in law down came the trousers, off came the pants and here is this neatly trimmed bush about 5 feet away from his direct eyeline and on with the trousers. Yes that's better says her sister and after seeking comment from my brother in law off came the top and bottoms and she was standing there naked before casually dressing into her gear.
We got in the car to go home and I said to her your a little minx. All I got was "I don't know what you mean". That in my language equates to Shut up or it won't happen again, so I just enjoy these moments when they come along

Here is a wee picture of her back in the day

A big maybe?
 

My brother, myself, and my wife all attended the same University. My wife and my brother were same class. They didn't know each other as far as I know, but had very many common friends. (The university had 51,000 undergrads, so it's quite common.) My brother hinted one time that he had seen her around in college. As I have gotten to know more of my wife's past, I now assume that it was probably at one or more parties with mutual friends. I know she was very promiscuous in college and have good reason to believe that some of that was in the group scene. So I've often wondered exactly what he saw of her in college. My cousin, too, was at the same university and in the group scene. She has a pretty good familiarity with him for someone she ostensibly never knew in college. So I've wondered about him to. The cousin may even have fucked her.

my cousins wife
 

He doesn't know it but when me and his wife were 14/15 respectfully I popped her cherry. We dated for a bit and fucked a lot. I was her first with a lot {handjobs, blowjobs, sex, fingering, eating her out}. I moved away and lost touch with both of them for about a decade. Finally moved back home and the first day I was home I saw them in the store. I hadn't seen her since we broke up, and hadn't seen him since the same time. So we started hanging out and stuff once I was back here and one night she called me up to help out with a heating problem she was having while he was at work. One thing lead to another and I've been fucking her for the last year without him even knowing. Damn she's so good, I'd stop if I could

Family rundown
 

I would have to give a rundown of family members that have seen either my ex's or current wife.
First wife, My mother and sister had seen her nude in a swimming pool changing room.
Second wife, My father had seen her nude many times, my brother several times, both brother in laws, some cousins, and many more have seen her pics.
ex girlfriend, brother and a couple of cousins, many more have seen her pics.
Current wife, father, brother, two brother in laws, and several have seen her nude or having sex many times, another brother in law and my mother and sister have seen her nude a few times. Most all of family and friends have at least saw nude pics of her from years ago.

Wife pics
 

i have showed a couple of friends my wife pics. she doesn't know of course. i have a nephew who was raised at our house. ten yrs younger than me. he has seen his aunts pics more than once. he has also showed me his wife. she has long meaty pussy lips. he has said many times he wish we could trade for the night, but neither of the ladies would ever agree to it.

Seen
 

With my fiance nudity is often seen. So far my brother, sister in law, three neices, nephew, her three nephews, her sister, three of my cousins and five of hers, and her voyeur son.

I'd love to be added to the list :) :D

sounds like casual nudity, except-
 

With such a wide range of family on both sides having seen your fiance naked I imagine yours is a family where casual nudity is not unusual- except that you call her son out specifically as a voyeur. What makes his viewing of your fiance "voyeurism" unlike the rest? Does he make a special effort to see her exposed?

Our adult son sees his mother
 

Not necessarily an erotic story, but amusing? I wrote about this in another thread a couple years ago.

Wife & I decided on a vacation to a Caribbean c/o all-inclusive resort.
At last minute, her early-20s' son and GF decided to join us. They knew that it was a c/o resort, and that we did the nude beach thing, something they were definitely not into.

We also knew that for sure, the prudish GF would never venture out topless much less nude, and for sure they would be on the other side of the resort. They were both into fitness and body building, but not nudity.
Not to mention that "son" would be uncomfortable hanging out with his nude mom and vice versa. Our household was definitely non-nude until our son left home.

All was good, having a great vacation. One day, we were laying out on chaise lounges on the beach, Red Stripe in hand, naked as naked could be. Suddenly I hear, "Hi mom" WTF? Here is son & GF, in bathing suits, walking up to us! Wife whips a towel over herself. My first reaction was to do the same, then thought, fuck it, this IS the nude beach, right? Anyway, they wanted to tell us or ask us something, that was their lame excuse for ambushing us like that.

After they left, the wife asked my why I didn't cover myself...... I said, "Really?"

I'm pretty sure I noticed GF staring at my junk during that 2 minute encounter..... The wife wasn't really embarrassed, just more startled than anything. I mean, by time we saw them, they had already seen all of her. But for sure, she wouldn't have been comfortable having a conversation while naked in front of sonny boy.

That's when I told the wife that while she yanked the towel over herself covering her breasts, unknown to her, her shaved pussy was totally exposed. Of course she asked why I didn't say something! I said I didn't want to embarrass her. She just rolled her eyes....
.

He does. Have seen him peeping through windows, trying to see under the bathroom door, etc. He's already groped her a few times as well

And it isnt all that usual in the family, some its casual a few have just been right place right time.

Heres her boobs

My wife's cousin has seen her.

I get on well with a cousin of my wife. We're not close and we probably only speak to each other once or twice a year, but it's always a good chat when we do.

One year I saw him at a family gathering and we got talking about one of our mutual interests. One of the topics in particular was about how we were both sad that one of the presenters for a related TV show was departing at the end of the year.

I made a joke about missing her great breasts as well as her skill as a presenter. In response, he asked me if I'd ever seen the pics of her topless that she had done early in her career before she was famous. I hadn't!
He had them saved on his phone, but with loads of family around it wasn't really the time or place for him to show me. He told me he'd message them to me later.

A few days later (and I'd mostly forgotten our conversation by this point), he messages me to say hi and thanks for the catch-up and then he sends me the topless pics of the presenter. I replied something like "wow - even better with nothing covering them, they're amazing!".

A few minutes later he replies with another pic of a different set of breasts which are huge!, with the caption "these are what you call amazing ;)".

We chat some more and he explains that got carried away and they belonged to his girlfriend (now ex) and makes me swear to secrecy. I do, and I make a joke about them being much bigger than what I'm used to (my wife) and that he probably doesn't want to know about that though (her being his cousin!).

He replied - and I'll never forget this - "tits are tits as far as I'm concerned! :D"

That was my cue! Before he could say anything else I replied with a full frontal nude of my wife and he made no secret of his appreciation. We ended up playing an unspoken game of one-upmanship, which he ended after I sent a short video of me fucking her from behind and then pulling out and shooting a big load on her ass and up her back.
Maybe watching her being fucked was a step too far for him, or maybe he'd cum and was now having regrets. Either way, he didn't reply for about 30 mins and then when he eventually did, it was to thank me for sharing, remind me not to show or tell anyone and that he should probably get back to work.

All told, he had sent me pics of his girlfriends breasts, some of her in lingerie, doing a striptease, and some videos of her masturbating.

I sent him nudes of my wife in various poses, the aftermath of a facial, her spreading her asshole for the camera and the video of me pulling out and cumming on her ass and back. In hindsight it was probably good that he stopped it there. I know I would've gotten carried away and shown him absolutely everything if he wanted it.

The next time we met, we agreed not to speak of it again and to anyone. I've been alone with him many times since then, often wondering if he'll bring it up... he's stayed true to his word and hasn't said a thing!

My Dad saw my wife skinny dipping
 

This happened a few years ago when we still lived in the Midwest.

My parents had a small farm about 2 hours from where my wife and I lived. We tried to visit as often as we could get away, but it probably wasn’t as often as we should have. They had close to 50 acres in total, mostly hilly grazing land that had a lot of trees. Only about 1/3 was tillable. It was a weird shaped parcel not very wide, but long.

My father fell in love with my wife the first time I took her to meet both of them. There was nothing he wouldn’t do for her, all she had to do was to mention that she liked something and he had it for her the next time we visited. I noticed that he looked at her a lot, and always complimented her about how beautiful she was. He never tried anything inappropriate and my wife just ate up the compliments. In truth she probably flirted with him at times.

About 2 years after we were married, we visited during late July, it was hot and humid, typical Indiana weather. My wife and I usually tried to get away for a little alone time and that normally was accomplished by taking a long walk back through the pasture and into the wooded area.

There was a small spring fed stream that ran the length of the property and as a kid growing up; the neighbor kids and I made a small swimming hole by damming up a narrow spot with rocks. The water wasn’t more than 3 feet deep and the area was around 30 feet long by maybe 10 feet wide. Just big enough to jump in and cool off in. It had a sandy bottom so it was easy on the feet.

When my wife and I got to the old swimming hole, I told my wife how as kids we dammed up the stream and used to sneak back and skinny did in our private pool.

The water was crystal clear and inviting and as relative newlyweds the next thing we did was strip off and were happily splashing in the refreshing water. We played for close to an hour in what we thought was complete privacy.

I had to pee really bad and my wife said that I had to get out of the water to relieve myself because she didn’t want to swim in piss water. So as a good husband, I trudged out of the pool and naked walked a few yards away from the water. While pissing against a tree, I caught a movement out of the corner of my eye. It kind of looked like someone moving amongst the trees. I thought I’d see if we had someone spying on us, but didn’t want to upset my wife or if there was someone, I didn’t want them to know I had seen them. I told my wife that I was going to check to see if some blackberries were ripe and would be right back.

I sneaked away from the swimming hole and using the trees to shield me, I circled around behind where I thought I had seen someone. Sure enough, I had seen someone, it was my Dad. From where he had positioned himself, he had a perfect view of the whole swimming hole, and especially my beautiful naked wife. He couldn’t have been more than 25 feet away from her. While I watched, she had stood up facing his way and was splashing water on her tits and pussy. Good old Dad was getting a great view of my wife, a complete view.

I watched for only a few minutes and then worked my way back around the way I had come and rejoined my wife. Standing on the edge of the water and knowing exactly where to look, I could see that my Dad was still there.

My wife said that she was cooled off and that we had better get back to the house soon. She then got out of the water and stood naked in the sun as she wiped the water off her body.

She did walk over to me and knelt down in front of me and sucked on my dick for a couple of minutes, she didn’t finish me off because she said that it hurt her knees kneeling on the ground. When she stood back up, I gave her a deep kiss and squeezed her tits and ran my fingers through her pubic hair and into her pussy.

She remained naked drying off for maybe 10 minutes or so before she slowly put on her clothes. Around that time I noticed my Dad had sneaked away.

When we got back to the house, my Dad was sitting in a chair under a tree, having a beer, like he had never left the area. I notice that he did give my wife a long look. He had a big smile as well. I knew that he now knew what my wife looked like totally naked. I thought that was pretty cool, I was proud of her.

He never admitted to seeing my wife, and even though I’ve shown her naked to several of my friends, I never told her about my knowing that my Dad had seen her completely.

He and Mom are both gone now, I occasionally think about him seeing my wife completely naked. I sure hope he enjoyed seeing her. I think he did.

Both my wife and I as wife's sister and her husband like hanging out naked from time to time.
First started by going to public nude sauna centers and nude beaches.
However, SiL did not want us to hang out naked together. She thought it would be awkward when her BiL got to see her naked and vice versa.

However, SiL husband is a real nude lover. He walks around the house naked almost all the time.
Even got caught by MiL few times.
So we all had seen him naked a few times, but none of the rest had seen each other naked.

Untill some years later. The 4 of us were on a weekend away during winter without kids.
We rented a cabin that also included a sauna.
After a day of hiking, the guys went into the sauna and afterwards the girls while we prepared dinner.
The fireplace was burning quit wel, thus it became quit warm in the cabin.
Not ideal when you just came out of a sauna and want to cool down (even after taking a shower).
So instead of wearing a bathrobe, us guys decided to be naked.
After the ladies walked in, they were a bit surprised to see the both of us naked.
It was the 1st time my SiL got to see me naked ... and for my BiL ... well we all had seen him naked more often.
Turned out that size wize, both my BiL and I were in the same department. About 7" and clean shaven.
Only difference is that he's cut and I'm not.

After dinner we we're playing a board game. The guys still naked, the girls wearing a bathrobe with a nighty underneath. All of a sudden, my wife said "it's not fair that you guys get to walk around naked while we get to stay dressed. It's too hot in this room to do so". Without even looking round or asking, she stood up and removed her bathrobe. But she didn't stop there. To my amazement, she also removed her nighty, so she was standing stark naked in front of us. That was the 1st time my BiL got to see my wife naked.

At that moment, 3 out of 4 were naked, but my SiL refused to go naked too.
Afterwards my wife did confess she did it because she was feeling a bit frisky.
Bit of alcohol and the sight of 2 naked guys did the trick.
Somehow the action of my wife had triggered something, because 2 weeks later, my SIL agreed that we all would go to a sauna center together. So I finally got to see her naked :) ... and my BiL and I could compare the looks of the 2 sisters.

But all has happened in a non-erotic, pure platonic way. And I don't think anything more will come from it.
I'm personally more in favour of smaller breast sizes, so although my SiL has a nice pair of DD's (vs my wife's C), she's not my type of girl :)
But on the other hand, I'm glad that it all evolved like it did, cause also our kids like hanging out naked on the beach and going to nude swim events. Hopefully they keep enjoying it, cause they are all their early teens.

Brother and his gf saw us fucking doggy style
 

Years ago when my wife and I were just dating we spent the night occasionally in my brothers house with him and his gf, and got takeaway food and drank some beer. Our main reason was somewhere to spend the night together. One night after a few beers we were very horny and couldn't wait to go to bed. At the end of the night we said our goodnights and went to their spare room. We were naked in record time and I was soon balls deep inside her.
Suddenly the door burst open and my brother and his hot busty gf burst in with pillows for us. I still don't know if they did it on purpose but I think they did. They got a great view of us both fully naked fucking.

Both my dad and brother have seen my wife at times when it's been chilly and her nipples are standing at attention. No big deal, it happens.

My wife’s family exposures are pretty mild. My cousin and her husband witnessed a quick nip slip in a pool at family gathering. One of my wife’s sisters husband has seen her in bra and panties, along with me seeing said sister in hers too. And same brother in law seeing Lisa sun bathing with bikini top undone but she was laying on her stomach so only a small bit of side boob.

Don't know which one of them is your wife, but she is definately right :)

My wife is a prude, she never uses sexy or provocative dresses, nevertheless she is a bit more relaxed in a family context and she has a do-not-care attitude for nudity or exhibitions, like a naturist. Here is an example.
We are in a family reunion at the country house of my wife's parents. We are in the garden sitting on sofas and chairs around a low table. Note for the readers the males around the table are her father (he is not relevant), the boyfriend of her sister, a far uncle of my wife and his two male teenager sons. They are not close relatives we have seen them only a few times.
My mother in law brings some homemade lemonade and starts pouring the lemonade in glasses starting from women. During the operation she hurts the table and she pours some lemonade on the thighs of my wife. She is sitting and quickly she lifts the hem of the silk dress and she starts to wipe the lemonade from her thighs with a towel.
The sister of my wife cries “take off your dress, lemon drops can damage the silk colors”. My wife without any hesitation stands up and takes off the dress, remaining in bra and panties.
My mother in law takes away the silk dress going inside the house, aiming to remove any lemon drop as soon as possible. My wife is standing in bra and thong, she is still concentrated in wiping her thighs, the lemonade full of sugar has a glue effect on her thighs. She pours some mineral water on the towel and continues to clean her thighs.
Everybody is looking at her. Everybody is smiling for the funny accident. Nobody makes any comment on her nudity. I see that my wife is standing semi-nude. The bra and the thong are made of a thin tissue (no visible lines under the dress) and now they are see-through under the sunlight. The nipples are visible as well as the dark spot of her pubic hair.
Her sister helps my wife to clean her thighs, she turns her exposing her ass (only covered by the thong) to the rest of the audience.
My mother in law comes back “the dress is OK, do not worry, now it is drying” (“do not worry? she is standing almost nude in front of four strangers and the only concern is the dress?”).
My wife asks to her sister “please take me something to wear”.
After a couple of minutes she comes back with a t-shirt. My wife wears the t-shirt and it barely covers her ass. She spends the next couple of hours only wearing the t-shirt, it is a continuous upskirt, but nobody cares after the previous five minutes in (transparent) bra and thong.
Later when we are alone I ask my wife “Was it embarassing being in bra and panties in front of everybody?”
She “Don’t be funny, we are in a family”
Me “The bra and the thong were see-through!”
She “Who cares…”.
My thought “somebody do cares!!!”.Women are strange, she was never topless even on a desert beach, she is careful with upskirts when we are in public or with friends and she was seminude in front of perfect strangers without problems!!!
Nevertheless it was very exciting for me!!!
