I have seen a few reviews and anticipate a great experience.  

because who really knows if they are "pleasing" each other.  The question should be are they WILLING to engage in girl-on-girl action.  Beyond the visual, it's hard to know if they are really into it, or just pretending.  So then you must ask yourself, "If it's a good show, do I care whether it's real or whether it's Memorex?"  

You have to ask yourself if it turns you on to see the gals in a lesbian encounter or does it turn you on to just have two gals working you over. I’ve indulged in a few “two girl specials” throughout the years of my hobblying and I found that rarely were the gals servicing me simultaneously for any real length of time. Rather, it was more like a tag team effort. So you have to ask yourself if it’s worth the double fee you pay.  

is most often what you get with a Kgirl double.  You pay each girl the full one-hour rate, and they give you 30 minutes each.  The big finish will be one riding your dick while the other one rides your face.  That's why if I can't confirm girl-on-girl action during the double, I would rather spend the two-hour price tag on two hours, either one hour with each girl separately, or two hours with the better of the two.  As you say, it's a bucket list item, so everyone should experience it at least once.  

I have a sneaky suspicion that I had her before under different stage name at LSC and she’s the definition of YEMV.

You are correct. I should have asked it differently.  I have done 4 different doubles and it was half half with porno like girl girl and both pleasing me.  

There was a new review posted and I am really looking forward to trying with them now. Especially after seeing them recently solo.

They did say they’ve known each other for a while. They told me separately.

I do agree everyone should try if they can. If it is either style.

I recommend the Stacy Cara double. They may not be very hot imho, but are eager to please and down for anything. They start out the gates by kissing and eating each other out. I prefer all the focus to be directed to me so I actually asked them to NOT pleasure each other - I know I'm a selfish fu*k - and had a real fun session. I don't engage in BBFS but was great sticking to the same cover going from girl to girl. I would repeat if they were prettier.

I do understand what you mean.  I loved the site of them interacting and it made them hotter to me.
