I want to relax and enjoy the experience. I won't even consider less than an hour.

And BTW the way I've been at this for about 18 months, done a number of doubles, but I don't really consider myself up to speed.

That being said everyone had their own comfort zone and you won't know what works best for you until you try a few different things.

Now that I'm full speed into the hobby (as much as my wallet will allow), I'm ready to finally experience two women at the same time.

Honestly, it's never been a primary fantasy of mine, mainly because I feel like one women is more than enough if you're doing it right.  Nevertheless, it's something I have to try at least once.

For those of you that've tried it, would a few minutes of two-girl action be enough, or do you need to set up a longer session.  

Often the ladies I visit have an available friend in the bathroom or neighboring suite, and I've been tempted to try to negotiate for the friend to participate for 15 minutes or so of the 60-minute session I've booked.   Is this doable/typical/crazy?

I'm not even sure I know the right questions to ask, but for a guy that wants to try two girls at a time, what would you suggest to make the most of the experience.

I have had two doubles experiences now, and one was quite different from the other.  I only did the first for an hour, and the second I set up for two hours.  I think you would want a minimum of an hour to really enjoy the benefits...and I found that the two hours allowed more creativity and involvement of all parties present.  I would also strongly suggest that you find a lady you really enjoy being with first, and let her bring the "friend" to the party.  You should also read reviews of how these ladies play together (if there are any), as this is important to understand how they will ultimately play with you.  Having a doubles where the ladies are really not into it will, IMHO, make things not all that good for you.

First, you need some time... minimum and hour. That said...

I wouldn't go there no matter how hot they are unless they already worked together as a duo. Sessions with two separate ladies can often be disappointing because they often don't interact in a way that is pleasing. What you don't want is taking turns between two expensive ladies.

And have fun.   Forget about a partial double...either go for it all the way, or just enjoy your time with the lady you booked with.  

Your comment about another lady being in the bathroom seems weird, though I once booked with a lady, and found that she was sharing the apartment with another provider when I got there.  I didn't inquire as to whether a double was available when the lady I booked with introduced me to her roommate, though I suppose I could have.  It probably would have worked...the other lady didn't leave the leave the apartment during my session, and just hung out in the living room.

Thanks for your replies.

you've convinced me that it'll be worth paying a little more to make it less rushed, so I'm going  to save my pennies, eat my Wheaties and find the right combo.
