Looking to give the wife a treat

Hi, we are a very genuine couple, very discreet, and totally honest - we are recently married and it has come to light that my new wife has this thing for having sex with another girl - we have never done this before as a couple but she has had one brief encounter with a bi friend long time ago and is keen to try it again. I know this is like looking for that preverble needle in a heystack but I though I would give it ago as she is very keen.
we are 45 & 43 and would not quite put us in the super modle bracket but hey who is ?
We would love to meet a single bi female who is not shy and who loves to have sex with both female and male . . . at the same time hopefully lol if you think you can help us please feel free to contact us - you will be glad you did :-)
