I was in Mettman last night. It was a great deal. this is not the place to come for 18 year old had bodies i would say the girls there were maybe 5-6 (for age or weight) and there was one couple and she was maybe a 7. I had 8 sessitions with 4 different girls all were good. Not a gf sex but a hard core sex. when i arrived at 4:30 there where 4 girls and 7 total plus one couple. i would say the amount of guys move from 12 - 20 over the night. the price was 110 for the whole night drinks are free and a not to good dinner.
Anyway it is some more info
I have also heard of a club called Xtreff that is the same but for 150 and the girls look better I will check it out the next tiem i am near the frankfurt area
