I usually try to earmark certain stories I like. I recently read one but I don't remember the name of it or the author. Basically, it was about a husband and wife who go to a bar for the purpose of her having sex. She gets picked up and taken in a back room with a stranger. The stranger's friend takes the husband back there to watch, not knowing he is her husband. I think the stranger was a cowboy. Ring any bells for anyone? Thanks.
