I am very bi and I am very selective when seeking a bi double partner.
If I have a woman who is not into it, well then...I can't be with them.

I want them to do almost anything with me too.

The only suggestion is when booking 2 bi woman, do your homework, make sure that they are into each other. There are double sessions in which the ladies do not interact.

It's more fun when the women are into each other.  More of a fun party.

I have found that, if the girls are not really into each other, then there can be "fifth wheel" moments where you are busy with one and the other won't have anyone to do.  

In a double session that I had, at one point it came down to me mish with one of the girls, and the other one was just sorta there.  Since she wasn't really into girls she didn't make any extra effort to involve herself with the other girl (kissing or face sitting...) so I felt like she was being excluded and instead of enjoying what I was doing I tried to involve her, but it was awkward.

That might not always be the case.  Some threesomes I have been in, when I was busy with one girl, the other girl occupied herself distracting me.  

However, for the absolute best threesome possibilities, you need 3 people who would be completely at ease in any pairing that might occur.

This is in regards to MFF threesomes.  MMF ones are a different dynamic, obviously.  Both because of the fact that men are less likely to experiment bisexually and also because while one penis can't accommodate 2 women at the same time, 2 penises can certainly accommodate one woman.  

I've done doubles with 2 step-sisters (anyone remember the SexySisters from Pittsburgh?) who didn't interact with each other but it was stil a fantastic time.  Too bad they're no longer in the biz.  These days, I would most likely be disinclined to do doubles unless both women were truly bi and that includes DFK.

Based on the context of your post, I'm assuming you're (a) a provider, (b) interested in, or fielding requests for doubles and (c) not the least bit interested in going the bi route.

If this is the case, my advice would be to just be up front about it.  If it is left unsaid, I suspect most guys would assume there'd be at least a little hanky-panky between the girls.  If you are asked for a doubles meeting, let the client know your preferences in advance.  Many will go ahead anyway because it means more attention focused on them, but others will pass.  But this is better than getting pushed into something you're uncomfortable with, or your client going into the meeting with the wrong expectations.

For me if I can ever aford a double - the lesbo action is the key ingrediant!  In fact I would love to schedule one for me and ex GF who is now Gay!

The whole point is being part of a pleasure chain- not ordering around two employees!

But that's just me ... (With apologies to Brett Favre)

...I'd want the women to be into each other, too. Girl-on-girl is very sexy to me.

If you want to try doubles without them being into each other you might try an AMP . It's a cultural thing with some of them. They bathe and pamper men as a team often ,and it would probably cost less there if you book during a slow time.
