and choose one of her regular doubles partners. They'll be experienced and comfortable with each other and can take the reins if need be. If you're booking a short meeting (1-2 hrs?), don't try to do everything you can imagine, just sit back and enjoy.

As told to my Co-Author (who insisted it go in our book):
"I'm boggled by how difficult it is to set up a good threesome.  I recently tried to set up a threesome with Little Lisa and a girl named Barbie.  That's the finger-trap girl that I've told you about.  I tried to be careful."
"Be careful about what exactly?"
"I tried to see if Lisa already knew the other girl."
"How did you do that?"
"First I showed Lisa the photos of Barbie and asked if she was acceptable.  Lisa said OK.  When Barbie arrived, Lisa freaked out, grabbed me by the arm, and insisted, 'Come to the bathroom with me.  I know this girl and we don't get along.  Get rid of her right now or I'm leaving.'"
"Oh my God!  Little Lisa freaked out on you?  What did you do?"
"I told Lisa to stay in the bathroom a minute.  I gave Barbie a C-note.  I told her to go shopping, and to come back in two hours, if she wanted to get the rest of the donation."
"What did she say?"
"I didn't give her a chance to say anything.  I hustled Barbie out the door while Little Lisa stayed in the bathroom with the door shut.  Then I apologized to Little Lisa."
"What did Little Lisa say?"
"She told me that she knew that girl by another name, from before, that she's been to some of the same clubs and parties in Long Beach and LA.  Lisa didn't recognize her current photos, but the moment the girl spoke, Lisa identified her and hauled me into the bathroom to explain."
"Then what happened?  Tell me!  This is so exciting."
"Lisa calmed down pretty quickly once I got rid of Barbie.  We had a couple of drinks and Lisa screwed the shit out of me."
"Did she know that you'd invited the other girl to come back?"
"I don't know, but she definitely made certain that she fucked me as hard as she could.  Jealously is a powerful aphrodisiac."
"Did the other girl return?"
"Yes, exactly two hours after I pushed her out the door she called me.  Lisa was still there and naked, but she was done fucking for the night.  I didn't want to upset Lisa by rushing her out, so I asked Barbie to wait fifteen minutes before coming up."
"Go on, what did Little Lisa do?"
"She got pissed-off at me, got dressed and was out the door in sixty seconds."
"Did you end up fucking the other girl?"
"A couple of hours later she knocked on my door.  It woke me up.  She jealous-fucked the shit out of me too.  In spite of how bad the evening started out, it ended up being a great night of hot sex."
"Oh, you gluttonous philanderer!"
"Tina, you say the nicest things to me."
"That's an interesting story about Little Lisa and the blown threesome that turned out so well for you.  I guess you just never know how something's going to work out."

that way nodoby's screwing for the first time. But, the best one I've done I had been with both girls individually but they had not met. One of the girls was experienced in doubles and one was doing her first one outside of scripted and directed porn. Experienced girl ravages inexperienced girl, who gets super turns on and returns the favor, and I'm a kid in a candy store. So it can work out however you do it, though I did take the risk that the girls would not get along, and it's not like I was going to get a refund if they didn't.

Yes....

Go into it with at least one gal you know fairly well and take her advice on the third member to the party!

My input-

Find one lady to be your "anchor" date. The lady that you are most eager to see, or the lady that you are most comfortable with if you have seen her before. Then tell her the "type of lady" you would like to have a double date with and let her offer you a suggestion or two from the ladies that she knows in the category you are seeking. The best double dates are ones where the ladies feel comfortable together in each others presence to ensure that you have the best time possible.

without making a production and letting the world know about it.  

There are plenty of providers advertising on their websites about their doubles partners and all the details you are asking.  

Why not use some self help using the so called hidden concept known to rest of the world as "SEARCH"?

Doubles...

I have done doubles with ladies I know already and I have done doubles with ladies I am meeting for the first time.You could reach out to some of the ladies you have seen in the past and are interested in seeing again ask if they have any ladies they do doubles with.If they do not you could ask if there is any lady who she is interested in working with but never had a chance.
I have had gents contact me who ask about ladies I have worked with before.

Sometimes it works one of my doubles friends he might have always been curious about.
On other occasions when I mention ladies I have worked with and if none of them are the guy's type he might mention other ladies.I have done doubles a few times with ladies I have never met before.
We both knew we were meeting for the first time and we spoke and met before the appt time just to make sure we are both on the same page.
Of course being with a lady you have seen before there is a certain comfort level in having her bring a friend.
But then there is also the excitement of meeting someone new and introducing two ladies to each other.
