So which porn star gives the best overall bbbj's?  And what is the price involved?

From my personal experience, Keisha, Raquel DeVine and Kathy Willets.... all  BBTC, all with much gusto and enthusiasm.  Honorable mention to Taylor Wayne, who made the most noise, moaning and slurping... (also to completion, although I've heard that isn't always the case).

In no order of preference:

Anna Malle, Kathy Willets, Shasta, Aja, Raquel Devine, and Marylin Star.

Doc
PS. Hoping to add Nikita, Jeanna and Anal Bridgette very soon.....

The BJ Hall of Fame starts with Bobbi Bliss (retired), Anastasia Blue (retired), and Alexandra Quinn (still going strong!)..

Lynn Lemay is excellent.

Cumisha Amado $$$, Mia Domore $$$$, Tricia Yen $$$$, the very best at any price.

Keisha and Candy Cotton, both to completion

In my experience, the best I've had was Ryan Conner... very, very soft lips, tc, slow and loving...

Honorable mention to Micky Lynn who's very good at it, and the least expensive of the ones I've met.

The worst: J.R. Carrington

Ginger Lynn, Bobbi Bliss, Nikita Denise, Raylene, Aurora Snow, Belladonna, Tiffany Mynx, Jenna Haze, Ryan Conner, Selena Steele, Samantha Sterlyng, Ashlyn Gere........i wish i could have sampled them all but the only ones that I personally have are Ryan Conner and Samantha Sterlyng.

Alexandra Quinn to completion and loves it....

In no order.

Ryan Conner
Alexandra Quinn
Jodie Moore

Does the Mynxster still escort? Wow, I'd not for 9000 on the DOW if I could see Tiff.

Obviouslly none of you guys have been with Tabitha Stevens.  A five star experience second to none.

How does one contact these girls??

the blonde one? how can she be contacted?

She changes from brunette to blond.  Just check the overbite, both are her.  
I saw her thru Nici's Girls
Not sure if she is still available.
Good luck!
