I'm not sure, but that's an issue of why I tend to not book a second visit with numerous SPs I've seen over the years. Lianne, Tanya (BLE), Kendra Banxxx, and Pamela (MFL) are four that immediately spring to mind in regards to restrictions of that nature. Contemplated about booking a second visit, but the thought of limited positions and only receiving a toothy bj and a handy as a result is what deters me (nice pleasant girls though). Happened a few too many times with various other providers, not fun at all.
So my guess is that you're referring to either Karmella, Lianne, or Leah Doll.
