I have a pretty good relationship wit my Brother in Law (Wife's brother).
We talk about women quite freely and when alone, have often talked about a shared love of porn.
A couple of weeks ago, I mentioned a set of pictures I had of a hot women that had been traded by her husband, describing her in detail.
He expressed an interest in seeing them, so I promised that next time I went over, I would bring a copy of them for him to see.

As I was pulling them onto a pendrive last weekend, I noticed that the girl was quite similar in skin tone and build to my wife, so on a whim, took out all the pictures that showed her breasts and/or pussy, and replaced them with close ups of my wife.

I took the pendrive around to show him whilst my wife and his went shopping.
We sat at the computer whilst he opened up the files. It was so hot to watch him staring at close ups of my wife's pussy as he zoomed in further and made crass comments about what he would do to it.

He asked to keep a copy to jerk off and of course, I obliged. It was so hot, sitting round the table for lunch with the wives, knowing that her brother had seen my wife's most intimate of areas in the minutest detail.
