I can confim some of what our friend Sir MarjALot says below. Had a chance to check things out for the first time a few weeks ago.
All things considered, I like Brussels set up more than Amsterdam. Less walking. There was a lot of car traffic checking out the girls, which was annoying, and not possible in Amsterdam.
Very nice selection of ladies. My tastes run more to slim, small curvy ass, thin waist, something up top a nice bonus. Lots of Bulgarians, Romanians, etc, and I do have a fondness for that exotic dark eyed/haired look. Several tempting blond goddesses as well, along with the usual uglies that lead you to wonder how they could possibly survive in this business.
Only time for two ladies, one good experience, one bad.
1) Good: Gina (?) from Romania was tall, slender, small but cute breasts. Absolutely gorgeous eyes. Started with good head, made sure I could see her licking and sucking. When I asked her to climb up on top she did so, and slowed things down when I asked her to, following the slow, deep thrusts as I guided her. When I suggested a change to doggy, she turned and massaged my balls as I thrust. Just wish I had not been jet-lagged, and able to go back for more after a rest/snack. Euro 40, but added the 10 to get extra positions. Well worth it.
2) Damn Bad: Elisa (?) from Bulgaria. Looked incredibly hot, short, slender curves in all the right places, stacked/firm. Cut bikini. Did the usual price check, she is all smiles and flirt, had me ready instantly. A little cuddling, stroking at the start seemed to set the stage well.
Problems started with BJ. She would not move her head/hair to let me watch her. I felt like she was using hands mostly, so suggested we move on to her on top. There she would NOT let me get penetration, wanted to just use her cunt lips to tease my tip. After some cat and mouse to try to get inside, I suggested doggy. Seemed like maybe OK, until I realized I was still not inside, she using hands and oil to make it feel like it (well done obviously, but not what i was looking for.)
By that time I was getting so angry it started shrinking. Then the madam rang the bell. First time I've ever thought maybe I could understand why someone would hit the lady. Not my style, so just responded that No, I had NOT enjoyed my session with her when asked, and did not appreciate her little tricks. Of course she did not understand! Didn't waste the time arguing.
What's the lesson? You never know what you are going to get. Still, at the price, and given the selection, the odds of having a good time with a gorgeous lady make me plan to return someday.
