Yes , 4 hands massage can be good, if the 2 girls work well together. I have asked many of my favorite girls if they have done them, most have, it is not that uncommon. It just cost twice as much.
Sometimes on a slow day you can get the 2nd girl for free. I prefer to spend the money on 2 seperate massages as I find 4 hands distracting. To each his own.
I think this topic has been brought up before in the General Discussion. If you're a person who will try almost anything once, go for it. I've done it(HJ/HE) but I wont do it again as I was curious. I'm going to try a 3-some at a AMP and I know a couple of places where I'll just pay the $40/HH and tip $60(total $120) to each of them. Since I'm mostly a FS hobbiest, I think I'll enjoy this better . Going for it at the end of the year and it'll be a christmas gift for myself.
