Funny, "Ménage à trios" is one of those goofs that works out well!

I've done several of these, by whatever name you prefer.  Had a great time in each case so of course I'll do it again--in fact I tried to set one up around the holidays with two of my favs but couldn't make the schedules work out.  

In every case the two women already knew each other, and except in one case they'd done doubles together before. In the case where it was a first time doubles, it was my idea and now those two women can't keep their hands etc. off each other, so I'm glad I suggested it.  

I want the two women to really be into each other but also love teaming up on me.  It's great when all three of us are actively involved, so there's not a lot of "just for the show" going on.

I have been with real girl/girl couples.  Some of my ATF's girlfriends are providers, including her bestie, and getting them together with me were some of the highlights of my "hobbying".

...when "all the planets align," so to speak. That seems to happen when there is plenty of communication before the event itself. I've found my best experiences have been when a provider with whom I've had multiple sessions and she has another provider/acquaintance/friend that they have worked with in the past. Assuming that I get along well with provider A, there's a good chance that I'll get along with provider B but I've also found it to be a good idea to do a meet & greet (social time for which they are compensated) just to make sure that we're all on the same page and compatible.

So far, all of my multi-party playtime has been memorable and great experiences -- but I do my research, don't jump blindly into it and rely on plenty of communication with a provider with whom I've had prior engagements. I'm working with a current fave lady (with whom I've had 3 sessions in the last 3 months) to put together another 3some in the next 3 months or so. She has multiple providers with whom she's worked previously and since we both get along quite well BCD, I'm fairly certain that we'll find someone with whom we can expand our "circle of trust" and have more fun!

First LucyFire, i am enjoying your open ended questions that let me relive some great moments.  

Done this twice in the FKKs in Frankfurt. Both times i was looking for shot 2 or 3 and the two girls are a big boost for that. Total focus on me. — didn’t even do any traditional sex. All BBBJ and DFK. If u have never done both at once (which clearly requires 2 girls) it is about the most mind blowing experience u can imagine. And finish CIM of course. Spectacular!

Ps at a strip club i hate it. They always seem to be more into each other. Don’t even bother anymore.

but I'm not so sure I can do justice to it now.   I almost had a chance to recently, but one of the gals took ill just beforehand.

It was wonderful, especially when the gals are into it with each other (You should let a gal you know well choose the other gal.) and also when they both pay attention to you after you watch them warm each other up.

Lying on my back with one gal's pussy on my face and the other either going down on me or doing CG on me is incredible fun.

 
Just remember to have  plenty of condoms on hand so they can change out quickly and safely.

... tho surprisingly not so far in this hobby world. I have enjoyed a few FFF with civvies and strippers and I definitely need the girls to be truly into other girls. As a girl myself I can usually spot great acting and that's ok if it's a 1-on-1 deal,  but if there are 3 (or more) ladies involved I want all parties to be engaged and truly turned on.

.... that can happen. I've reviewed some here, but I've done a lot more in an area where this isn't the prominent board.
I've always had experience with at least one of the ladies prior to the threesome. Sometimes both of them separately. I've also enjoyed some foursomes and once a 5way fest.  
I've done some where it's been a BDSM session with a GFE finish. I've done some where the ladies were so into each other, I just inserted myself into the fun.
I've had sessions where I was the focus of both ladies for the whole session.  
One fun threesome was one of the ladies first time with another woman. It was so hot watching her eat pussy for the first time and the other lady cumming so freaking hard while I came in her mouth.  
The common denominator was that we were all having fun.
There are a few pairs of ladies that I want to do threesomes with in the future. I'll have to be patient and wait for the right time.

The experience is going to be entirely based on the company. Some threesomes advertised by provider friends turns out to be a ploy to separate money from the silly fool.

Have tried few and none turned out to be mind blowing in reality.

The first time I tried to set one up, a provider I knew was touring my area with one of her provider friends and I set up an appointment. Unfortunately, the provider friend could not make the tour. Provider offered up an UTR friend from this area, I declined since I didn't find her attractive (I saw one pic and she had a mask over her face so it's possible I just happened to see a bad pic).

Second time, I brought up doing a threesome with my ATF while she was touring my area. She seemed interested in doing one. Since I'd only seen touring women or women when I was on vacation, I didn't have any local recommendations for a third. A week before our appointment, she sent me 4 or 5 women she'd be interested. I picked 2, we reached out to them, no luck.

I do plan on having a threesome. I do have a couple of leads for this year. I saw a local provider last year and I would like to do a threesome with one of her friends or when my ATF comes back into town. Also, there's a duo ( a real life couple I believe) not too far from my town. Maybe if the stars align, we can be a threesome together.

So many stories! I love it! My wife and I met while working at a bar some years ago before we knew about the online world, and have been together ever since. In May it will have been 10 years, with 4 of those years married! I feel we have the perfect dynamic. Threesomes are the perfect spice.  

I don't know what's better though...knowing someone is watching us? Having a "part-time" boy toy? Seeing the excitement and wonder on a clients face that has never seen a TRUE girl on girl love? Or the all-around pleasure triangle?!

Is this for real?

Ask any straight guy "What are your thoughts on a Menage a Trois" and it will be the same response. "Where and when!" Those who say "Never!" ate liars.

I've had the privilege to experience the Menage a Trois on numerous occasions and say "Yes! Do it for your country but most important! Do it for yourself!"

For my 35th birthday, I was the recipient of a Menage a cinq! My gf offered this up for me with several of our friends. It could have been a Menage a Six, however, my gf didn't want to participate.  

That night I popped off 3 times in 3 hours and a fourth time with my gf and her bestie who stayed the night.

To answer your questions in order of appearance...

Yes
Yes and Yes
Yes and Yes
Yes and Yes...mutual between everyone
No and Yes...there for the ladies!
Experienced it already
The problem with G/G action or true lesbians I'd figure would be the lack of intimacy with mois.  

My previous partner's sister was full blown lipstick lesbian and all of her lesbian friends despised the idea of being with a man. How could you f$#k a woman, let alone 2, who thinks having an 8" sausage in their hoochie is like falling ill with the plague?!

I've only had one threesome and the two girls were into BDSM - for each other, not necessarily for me. Only one of them played with me at the time while the other either watched TV or looked at her smartphone. Every once in a while the one who wasn't playing would unsuspectingly stand up and smack the girl who was playing on the ass with a round, leather paddle. And I mean really hard, not just a love tap. I said WTF the first time I saw it but the girl who did the hitting told me it was just the way they liked to play with each other and not to worry.
