someone solo. My best threesome ever did not even include FS (just turned out that way). Everyone was into doing everything with each other (including toys, strap ons, lotions, restraints, etc.); had an incredible time with 3 O's for me and who knows how many for each of them; was having too much fun to realize until afterwards that I never did have FS, and couldn't have cared less. A great O is a great O regardless of how you have it. Fun, laughing, squealing, begging, moaning, screaming (the girls did some of this too....lol) coupled with a few major O's makes one smile for a long time. Doubt if FS could have added anything to that night (ok, and the next morning too).
