I've had good and bad experiences with duos. I was expecting something from a porn scene, but was highly disappointed: although the girls were friends, they really didn't interact with each other... it was like being on 2 separate dates. A couple other times, though, I had the luck and pleasure of being with 2 women that were not only into each other, but encouraged a full-on menage a trois.  

When you're looking for a duo, be sure to check out the duo review and see if there is real interaction between the women. Sometimes asking is good too... just ask how much attraction there is between the 2 ladies. Have fun!

My experience told me that better off to just focus on one at a time, unless you book them for a whole day.

Duo experience

I have to agree that a duo is most fun when the two ladies are into each other as well as me. I had a duo with a couple of ladies and felt that by the end of the date we hadn't been a true trio. I went for a second date with them and asked them that all of us be involved with each other. It was much better the second time around. Ask nicely in advance and you may be pleasantly surprised. I am having a duo this week with my two favorite ladies. They have never met before but have complimenting traits. I'm hoping for the best and I'm sure I won't be disappointed.

My Friends page is where you'll find who my favorite is.  She's at the top!
Absolutely the best time, everytime, because of how we get along and are totally lost in the moment whenever we're together.  Super Hot
In a trio, it's so important that the girls are into each other.  Otherwise it honestly kinda sucks and can be ackward...Xo's

After seeing dozens of duos I can say that most have been good,  several outstanding and a few mind altering. But for me an essential element is that the girls are into each other as much as me. If you want to avoid a letdown make sure the girls are comfortable with each other and are ready to rumble.  Discomfort,  awkwardness or timidity are death to a duo session.  

On the other hand if you're happy with the ladies just focusing on you then you should have no trouble finding that.

Good luck.
