I am looking for a story from a couple years ago. It was about a young married guy who goes to a city for his job and happens to check in on his mother in law. When he finds she is not living in a run down place he makes her pack and brings her to his home. He tells her what is his is also hers and they are doing fine, things start to heat up and she ends up becoming lovers with her daughter and son in law. I would just like to read it again.
