If a kgirl advertises duo, do they also offer bbfs in those sessions.  If so, can you do both girls raw at the same time?

the answer is yes.  I call it the Kgirl "exacta" . . . . . A rare opportunity to catch two DIFFERENT STI's during the same session.  You only live once; go for it.   Lol

Or if you use a cover do you have to change the cover from one girl to the next?

then it depends on how well the two girls know each other.  If they just got thrown together as roommates on the luck of the draw, they may require a cover switch.   In my experience, in a GFE duo, some MAY ask for a cover change between girls, which can get really cumbersome going through a half-dozen covers in an hour, but the majority of my experience has been that they don't require a cover change if it's a covered duo.  If you are on good terms with the booker, you can ask if he/she has any feedback from other customers who said the duo performed DATY on each other.  If the answer is yes, it's less likely that you will have to switch covers.  They are not likely to require a cover switch with a pussy they would eat.  Just my observation from my own experience.

They have to be either both bare OR no condom switching.

Condom switching kills my boner. Already too much shit going on in doubles.

 
Most of this info can be found out via po.

I'm not sure how many more doubles I'm planning to have myself tho. Price of doubles in the bay is ridiculous compared to solo sessions. It's up to 800 now while a solo session with one girl is in the 280-320 range . That's close to two and a half times the markup. Thankfully the doubles I've done were 700  

You can bang two different kgirls for two hours and then have 200 left over to fuck a corg milf in the ass for half an hour.

It's a great thing for bucket list and if you really like both girls I suggest you go for it but it's not something I'd do very often.

I did a duo and they did not make me swap as I went between the two of them.  I just shrugged and did my thing.

... I want the girls to fuck, kiss, and DATY each other.  Hard to dind.

I'm sure everything has a price...

The few doubles I've done, that happened. The daty perhaps wasn't as extensive as you'd like, but personally I am not into lez stuff all that much so even tho it's hot, it wasnt my priority.

The again, I chose my doubles very carefully. 75% of the girls I've seen in doubles are in my top 5 service girls, so I went for a whirlwind of service, orifices and fluids all over. It was spectacular. But again Ive had a lot of sessions with all of them prior to even doing doubles and we were all familiar with each other.

I've done one after the other. But being singularly phallic hinders my ability to do both at the same time.....
