To be honest we have been doing this for quit awhile (swinging) and love and enjoy our fore-sums so much , however we have only had a few MFM only, and each time has been different set of circumstances, which in itself made it exciting. One of the thrilling and most enjoyable things about swinging is watching your spouse with another partner. Sorry we can't be as exciting as most of you have been about your MFM, but we have enjoyed reading and learning from all your comments thanks you all.
