This scene is from RK's In the VIP. That site and Havoc Hailey's [nobabe]Money Talks[/nobabe] are two of the hardest sites when it comes to identifying ladies. It's possible but you may have to keep bumping this thread for a very long time. Just be patient. Someone may know who they are.
Lastly, the other site that's very difficult for IDing babes is Bang Bros. Dancing Bear.
