It was a mixture of shock and excitement. I have no doubt he was "using" the video. That in itself is exciting to me. But the thing that got me the most was all of his friends suddenly starting to drop in after school. I could see the way they looked at my wife.
I haven't discussed this event with my wife. I don't know if she knows the video exists but having looked at it several times I can see she looks straight at the camera/phone. There was no attempt to cover her nakedness in front of our son. Makes me wonder.

Back in the day, my parents, my sister and I went on holiday to the seaside yearly.
My girlfriend at the time also went to the same resort with her parents and younger sister.
Both our families knew each other pretty well.
At our place, we were raised pretty prude. Never saw any of my family naked, bathroom doors were always shut and my mom and sister dressed rather conservatively.
So one the 2nd day, both our families went to the beach together.
Packed with towels, drinks, some food, a ball and frisbee ... the standard typical sterotype image :)
So we set down, unpacked our stuff and started to undress down to our bathing suits (speedo for me back then)

Now imagine my surprise when my gf, her younger sister and her mother didn't stop at their bikini, but the 3 of them all took of their bikini tops.
Then imagine my uttermost surprise when my mother went topless too ... hesitantly followed by my sister.
The prudes I never had seen topless or naked in all those years!!!
So there we were, my dad, my gf's dad and myself, joined by 5 topless women.
And to top is all off, they were not just laying there ... they were actively playing some soccer and throwing the frisbee ... so jiggling breasts all over the place.
And it wouldn't be the last time that holiday this happened.

Our relationship didn't last however, but ever since that day, things around the house were a bit less prude.
But what I most remember were all those mixed, sometimes awkward feelings and thoughts.
Me seeing my mother and sister topless. Me seeing my gf's mother and sister topless.
My dad seeing my gf topless ... and her mother and sister.
My gf's dad seeing his daughters and my mother and sister topless.
But all fun memories when come to think of it.

Family holiday
 

We have been on holiday with my dad and step mum. On the beach we frequently went to, it was pretty normal for women to go topless. Both my wife and step mum went with the flow. My step mum is quite petite and has A cup tits with small nipples. I was surprised she went topless, as she is normally quite reserved in public. My wife on the other hand, is around 38D and been topless on the beach quite a lot. Although I have seen my step mum totally naked, she walked out of the bathroom, not realising anyone else was about. I don't think my dad had ever seen my wife's tits before.
At the time, it didn't really seem like a big deal.

My dad has seen 2 of my gf topless, but never my wife.
Which is quit funny cause she's the one who is the least prude and has gone topless or naked on so many occasions. However he has had plenty of downblouse, braless, skimpy clothed, tiny bikini and breastfeeding views over the years, that he must have a pretty good idea if her shapes and assets. Which like @pedels indicated is not really a big deal, but I have always found it to be a bit special that he could see/judge what his son can play with :)

But who knows what the future might bring ;)

My brother "found" my wife's nudes but he never said anything about it. I'm kinda disappointed he didn't ask for more.

I always find that hot. I’ve written about it in other threads here.

My wife gives me the same types of details about other friends / family members (her friends, her sister, her mom and my mom and sisters). It turns me on knowing a little bit about what they look like under their clothing.

Got on the subject of my nest home device and how it caught my wife outside my home office gathering clothes for laundry and stripping on cam. Asked if he wanted to see, he said yes so I showed him. Let him know I had nude pics of her and showed him two before he freaked out about it and it ended. I would have showing him a lot more.

I fully agree with the last few Post here!
 

If your not able to get a view of what those family members or wives of other friends, its exciting and great hearing from the wife on what they look like under their clothing or even what they talk about!
There are times that I have to get my wife to change the subject and get off the guy talk that the women do plenty of and only talk about the women~ lol
There are also times at gatherings when your close enough to hear what the women are chatting about and it can get real thrilling to hear!
I find it very interesting when the women are talking about those vacation bathing suits and what the latest trend is with them in the special area that they'll be going and how daring them might want to try and get?
The latest stuff was about so high cut the bottoms are getting and showing lots of what I call Sweet ASS!
They had a conversation just awhile ago about a new BRA that was out and cost plenty, its specialty was to make sure those Nipples could be seen thru any clothing the women were wearing!
I have to agree with what the women here said, that if they want their nipples to be seen they'll just wear a sheer top and No BRA! Later they talked more playful about cutting holes in their clothing and have their breast hanging out and exposed! That's when I butted in and told them I agree on being able to have their tits outs, cause seeing them in motion always works wonders on Me! lol
;)

Thanks, JustinTinMan and Hornyinde for your thought and in put on this Subject!

Full ass on show?
 

Been on a few holidays with wife and my family, but she has always worn 'normal' bikinis. On our last holiday (alone) she took to the current trend of wearing very revealing thong bikinis. She keeps saying, 'I'm not wearing this in front of your Dad'... we'll see...

An opportunity?
 

It sounds like your wife has clearly thought about him watching her parade around with her ass bare while he watches, and knows he would view her exposure in a sexual context. She might be "asking" for permission to do a little "accidental" teasing, or for a direct order from you to let him see....

Or not. :)
