Wanting to try FMF now...

Has anyone ever tried sharing their husband with another man? How was it?

So my wife and I tried MMF and it was super sexy and hot and I can't wait for that to happen again, however, the thought of small group sex turns me on a lot and I want to experiment more. I love my wife dearly and don't desire any woman ever nor do I want to be with any other woman but I am curious to know what it would be like to be loved on my two females. There are things I think about that would be hot for a man if there were two females and it would be fun! Should I stick just to the fun of MMF and not risk making my wife jealous?
