I have sister that is a few year younger than me and never did I ever think about or talk about wanting to see her Topless or fully Nude!
But having a wife that is playful and always thinking about new stuff to do or see in a sexual nature, I never know what to expect when I come home?
Having plenty of Naughty picture albums that are stored away and only use for special purposes, my wife has the nature of leaving some out that others will see them and having that nature of wondering what kind of pics are in them?
Having an Open Door policy at our house for family and friends & neighbors to come over and make use of our Pool or Hot tub is always welcomed! My wife most of the time will know who is coming over and has a spare bedroom ready for them to change into their suit! This way their not tying up any bathroom with their clothing.
Then soon after if my wife's plan works out right, that person changing will open up the Album's and be Shocked to see pictures of Us, along with many other neighbors & friends Nude and in playful situation's too!
So when my sister that shows without her hubby to use the Hot tub, they both can use it and get in their chatting time on family business!
My sister has to ask my wife about the naughty pics she seen and ask her tons of Questions, cause that's what people do!
It must of sparked something in my sister of a sexual nature, cause she just kept on being more interested so my wife asked her if she wanted to pose with her in some SEXY sheer wear along with doing a bit of exposure!
My sister did happily agree with a few Rules of her own, we couldn't tell her hubby cause she'll do it when she was ready! The other was that I would take the pics of both of them and would have to be as exposed as they would get!
When I got home and was asked about doing this besides being in shock myself, I did agree!
But for my 1st time ever being able to see sister now sitting on the bed next to my wife and both of them all NUDE was just a erection maker for me! My sister is huge on top with large pointy nips, but a short time after when she moved her legs around I got to view her pussy with a nice trimmed bush on top!
I must say, this made my day and it was nice having more of these moments some days after again!
