walk-in brothels in Frankfurt are similar to hotel buildings, but without receptions.
You will walk up the stairs and a hallway will lead to individual rooms.
If the door is open the girl is waiting for new customers.
If you like her you will chat her up, negotiate and decide if you want to engage with her or pass to the next floor.
If you find the girl of your choice, she will ask you inside and close the door. You will deposit the negotiated fee on a table and both of you will strip, get a bit closer and may even engange in petting and kissing depending on sympathy and negotiation skills. Then she will lead you to the sink and wash your little friend with soap.
The girls are usually very photoshy but if you pay a bit more and promise not to show their faces, chances are you may get lucky, but it is an absolute exception as the house owners and pimps don't like to see it.
After you have completed
the act(s) you will go to the sink to wash again, dress up and the girl
gets ready for her next guest after a short chat and kissing you good
