If you have never fucked a window girl then this video might be of some help. The Lady explains the procedure pretty well. Window girls are only for beginners and tourists. When you have been in the hobby a while, German Partytreffs and FKK clubs are the only choice.

NOTE: SOME ENGLISH IS SPOKEN IN THIS VIDEO. Despite the fact that I don't understand a word of Italian I really enjoyed this video. It really brought me back years when I used to fuck Window girls in Amsterdam. Compared to what I get in Germany these days, Amsterdam window girls are shit. Still though the memories have come flooding back.
