My wife and I are together for 14 years. We both enjoy making nsfw pictures and videos for our own collection. I’m 32, my wife is 30. I have a colleague, 42, and we can openly chat about a lot of stuff. Also nsfw, because of this he knew about the pics/vids. He got to know my wife too through multiple work parties and he did admit to finding my wife very hot. My wife has her moments that she does enjoy the attention from others so she was flattered. I don’t remember the exact details, but we came to a point where we share our nsfw pics with my colleague, my wife loves his reactions on them and that he gets hard from watching her. Now about once a week we send over some stuff for him to enjoy
