Do you know a window girl that would let me lick her ass? Thanks

Probably plenty. Ask around. Its hard as a newbie (not that I'm a total expert) but you really just gotta rock up to that window and ask. They've heard it all before. Expect to pay more than 50 EUR though. I'm not saying its impossible to get it for 50, but just be prepared.

Thank you

It was many years ago i visited Rld in Amsterdam, but
almost everyone that i tried this on, let me do that.

I usually started to lick their pussy before i changed to
their ass. No one of them charged me extra for this.

Just one in Brussels Rld that did not wanted to have
her pussy licked, but for 10 euro extra she let me lick
her ass.

This is possible.
I think you will have to negotiate.
If you ask 30 min for 100E, with this and SF multiple positions, everything off....
I think you would get a yes most of the time.
Remember, 50 is only 15 minutes.
If that was ALL you want to do, you would usually get a yes, but they really expect a quicky for 50.
