Does anyone know a RLD girl that would allow me to lick her ass? Thank you!

Someone wrote a report with that on the menu. And then some:
Wallen, Dollebegijnensteeg 115, Dispina/Villy (Day)

Check it out in the window girl section

Allow you to lick ass,
or expect you to service her ass as part of the famous
"Welcome to Amsterdam, now get busy making me come!" package?
I guess you have not met Maxx.
This is easier to find than you might expect.

Lots of them they do it. When you negotiate the session at the door (usually 100 euros) ask about licking and if they say yes,almost always that means pussy and ass as well. I can recall at least 20 girls which they allowed that. Bulgarians Pamela and Mimi, brazilian Monique and many others which I don't remember their names.
