Looking for bi-provider for first time experience.

My wife and I will be in LV on 10/30 - 11/2.  She is mid 40's, nice looking with a nice build.  She has had some bi-kissing experiences but nothing more and would like to do more.  We are looking for a provider for later at night. After some time on the town and a few night caps.  Looking for a provider 35-45, nice build, not to thin and chatty.  I would not be participating unless my wife decides she wants me to.  Any ideas?  Thanks
