Help Me Find This Story

I know one of you will know this one. I read this years ago. The story was about a hot wife and her husband. They got on the subject of her needing more opertunites to have sex with men. They came up with a plan to pretend to get seperated and that would open the door for every man including his friends. So they announce they got seperated and he moved out. She started getting guys hitting on her that she never expected thought about her sexually. Being the slut she was, she had sex with all of them and the husband was secretly watching. I cant remember if he was watching through a one way mirror or what. It was a wild story. Anyone remember this one?
