If you are doing a three-some with two gals who are into massage, then of course there is going to be a lot of sex going on.

If, on the other hand, you're at a legit massage place, you're just going to get a 4 handed massage.

Then, there's a lot of room in the middle depending upon who the providers are and what the understandings are.

A good four hand massage is a thing of beauty, but the gals have to be pretty expert at massage, and they should be using a massage table.

Mr Fisher makes good points. In the context of "Massage" it is not a duo like a regular session with a couple of providers. Multiple hand massage is Awesome. I personally have only had 4 hands but a provider friend of mine says she has had 10! so it can become a real art. With a massage I do not really look for a lot of interaction between the ladies. If you are on your stomach you can not really see them well anyway. However on the flip it can get more exciting with some mutual stimulation.

The unique thing about multiple hands is your mind can not process all the sensations at once so each touch can be a surprise/pleasure. It is kind of like a nonstop roller coaster ride. Experienced masseuses are a must and can leave you with a feeling you soon will not forget.  

With FBSM it tends to be more about the guys pleasure than pleasuring the ladies like a regular sessio

the place was closing within the hour, so they offered me 1/2 hour of that instead of my regular 1 hour massage.
It felt rushed to me.
Much of my enjoyment of massage is the relaxation, it just wasn't there for that massage.
Even the lady who I always liked at that place didn't seem to do as good a job as usual that day.
Even for legit massage, I think the best ladies have a gift of caring touch that really makes you feel they are connected to you for that hour (and some literally are, only losing contact with my body for the moment they go to retrieve the hot towel).  To me this is a one-on-one connection.  I suppose you could have 2 ladies who are completely unselfconscious who perhaps could even feed off each others energy and attention to you.  So maybe I should stay open-minded that if done right this could be a good experience... But for now, I'll stick with the 2 hands of my favorite lady.
