I have noticed lately that a lot of touring providers travel with other providers and advertise a doubles with each other. Several local providers also seem increasingly to offer doubles. It may not be a recent trend, but it seems that way to me. I have only done one doubles during my time in the hobby and that was mostly to check it off of my bucket list.

1.  You get twice as many warm places to put your dick.  

To say a FMF is just 1/2 the effort on their part is incorrect. If it's a good 3some they're both putting on a show for you and giving you some hot views and moans etc. while they play, always keeping you in mind. It's going to be different than if the 2 of them were alone together.

both gals simultaneously work on me.  A common gambit is for one to be sitting on my cock while the other straddles my mouth, but there are plenty of other variations.

You stated you did one doubles but with who?  Using your alias makes it impossible to know. When you state it looks like a better financial deal for the providers than it's really not even worth it to explain to you the fun of doubles. I've always thoroughly enjoyed my doubles adventures.  

A few years back, I had two girls for two hours. They were both in their early 30's. Honestly, every time I ever heard of a friend who had a 3 some, it was two girls that let him in on it. In this case, both girls were there to pleasure me! I sat on the couch, one girl sat on each side of me. I was kissing one, then the other. It was quite something to see these girls go down between my legs sharing my rod. They were laughing, having fun. Swapping condoms between girls was a little awkward, but the view was awesome. One was DATY to the other while I was behind in doggy. Arms and legs everywhere. I agree it was expensive, but years later I still think about it. It was worth it for a once in a lifetime experience.    

I was discussing doubles with a provider and she told me about a FFFF session she had as a civi. It sounded hot!

mmmmmmmm.....one day!

I never had a double session with full-on lez action, G-G toys or anything like that. The most I got out of it was the obligatory double-BBBJ. Two mouths simultaneously attending to my little friend was hot! I especially liked the double harmonica action, just like in the movies ... but no longer a big deal. Scratch that off the bucket list.  

I was also worried about showing a preference for one or the other and if that would offend anyone. I know that's a double edged sword: "OK, so you clearly like me more. Go fuck her for crying out loud and give me a break!"

Vixens made us boys watch for about 40 minutes before we were invited to join.

once was a bonus, my date's friend offered to watch... very Mehr

When two or three ladies are all focusing on me. One riding my face, another riding my cock and even a third doing all sorts of things. It can be intense or it can be gentle and intimate. Or, it can be both at the same time.  
Or my voyeur side gets satisfied watching two ladies pleasure each other or like the other night, one lady and I mutually masturbated while the second lady danced for us. It was awesome.  

have both enjoyed one-on-one time with. This will be my 4th FMF session and a birthday gift to me.

...I have to try this, I haven't done this in P4P but several years ago I had a GF a (friends w/ benefits) that invited one of her GFs to join us for an evening of just talking & making out, I didn't know these two were into each other & once they started w/ their kissing & caressing each other I couldn't help but join in. Our games went on most of the night & one reason I haven't sprung for a P4P FMF is one hr. would not be enough & I couldn't afford two hrs.

these 8 sessions have involved 12 different women and they have all been great!  

I will admit that they are not cost effective in terms of dollars per orgasm.  I might note, however, that P4P is just not very cost effective anyway you look at it.  Honestly, I can get the cost per orgasm down to zero with self service.  

agree pretty much with Mongo. If you are trying to justify the cost for 2 providers, then you aren't enjoying the experience, you're keeping score.  
I've done 2 doubles and they were very different and both were awesome experiences. I will do doubles whenever the opportunity is right. Sometimes you want the one on one , but sometimes you are in the mood for something different. Isn't that why you hobby? Otherwise screw your wife or SO a couple times a year for the rest of your life.

That banger/vacationer distinction makes sense to me. When I read a threesome review here at TER, I tend to be disappointed by the banger ones because it does seem like they wasted their money getting the second girl.

Very well explained! Good onya. I have enjoyed about 18 fmf and a couple of ffmf in the last two years.  I always do at least 2 hours and sometimes 3 hours.  

tell the girls.. this isn't about me.. It's about us.. all of us should enjoy ourselves..  
I have done three of them.. the last two were great.. the first one was just OK.. I have another scheduled.. but it's been bumping along schedule wise.. child care issues.. I have found that I enjoy them a lot if the two girls enjoy each other too.. that's important.. so who cares if they would do it with each other for free.. that's kind of a strange attitude.. the fact is they are enjoying each other and also me.. it's fun.. not an investment..

I've done a couple dozen over the last 15-20 years. A very few have been disappointing and several have been unforgettable. A bunch with my ATF, who has rarely let me down. Nothing turns me on more than having two girls going at me and then periodically breaking off to go at each other. I love watching them doing each other while I sit out and rest up, knowing I can move back in on either or both at any time. However, as has been noted many times, chemistry between the girls is key. Having them both focus on me is great, but I don't feel like I'm getting full value if they're not focusing on each other as well.

I think the issue is offending the other woman.  It is a bit of a touchy thing because the couple of times I have done it I got the sense that one woman expected to be the "main one" and the other one felt a bit left out.  I think it is only natural.  
My take is that it is only good if you are out of town someplace with a really nice hotel suite and you have plenty of free time.  I think what happens if you try to rush these things it ends up not being as fun as it should be.   If you have time you can have multiple sessions where each one can take turns being the center of attention.

...I love the chance to hang w touring women,they know each other&are comfortable w each other-for me it's a chance to have different tastes in my mouth and have several amazing options for placement of my sperm!

One of my ATF's offered me a reasonable deal of FMF.  A little lesbian action and fairly scripted session which ended in 45 min or so.  That being said, the sensory experience was amazing.  Double BBBJ action was great, but what really did it was nipple action.
