Well I know this sounds hard to believe.. I have never been with two girls, at the same time, in bed, having sex together.Id like to make this happen soon I have one hot! provider ready and willing and Im looking for one more sexy woman to participate anyone interested?..... other than the $$$ what other tips on making the experience unforgetable should I know? and what kind of expectations should I have? or what from me would be expected by my providers  thanks for any help

You could have the first provider recommend someone.  Or maybe that's not a good idea?  Is it a good thing or a bad thing for the two women to know each other?  I can see where it would help, but also where it's not really a good idea at the same time.

I haven't had the pleasure of my first threesome yet so I'm just throwing out some thoughts.  Curious to see what the experts have to say however.

You have lots of decisions to make.  Start by deciding what you want.  For example, a show where you watch two girls in action or do you want to be the center of their attention.  (Personally I like some of both.)  I've had good luck with girls who know--and are attracted to--each other.

I have had the pleasure of a 3 some once and I wanted to make sure everything went according to my fantasy.  I know this does sound very spontaneous but I'd think it through and decide exactly what you wanted to do.  You don't have to choreograph their every move but make sure you get to do/see those things that you want.  As for me I made sure that I got the double-sided BJ and that I did both girls doggie while they spoke French to the other.  Oh what a sight!
Good Luck!!!
P.S.  Oh, one more thing, you might want them to know each to make sure they play well together....

Somehow I've managed to be in several threesomes.  The first couple of times were almost accidents-- they happened naturally.  But then I noticed a pattern and kind of figured how to make it happen more often.  That was back in the real world though-- not in "fantasy-provider" land!  But I still think a lot of what works in the real world can help in our fantasy world-- these are still real girls even if they are getting paid.
Personally, I think it will always work better if the girls know each other and are friends (it helps a lot if they are bi-sexual and not just putting on an act too).  They will have a lot more trust and therefore it will seem more natural.  I like to watch them together for awhile-- it is fascinating to watch two women make love -- and you can actually learn a lot from it.  Then join in when the time seems right or more often than not when they ask you to join in.  From that point on just let it happen.........

Bring a video camera and play pornstar....lol...
