We have been swinging for a while, and I have been hinting to my wife that I would to like to watch her with another woman.
She finaly said that she was willing to try as long as I she could watch me with another man too.
We decided to do a bi-swap with another couple. We all had a few drinks, then we all got naked and the women said that they would mastrubate each other if we gave each other hand jobs.
They did, and we did. Now wife wants us to all do bi-oral next time.
