Visiting Berlin End of July for 2 days.. need recommendations

So my limited Hobby Experience involved 6 hrs in Frankfurt once at FKK club which happened to be slow day. overall OK. girls were hot but not enough time and mostly all smokers and no GFE. Kosher cowboy gave me good advice last time.

I would love ti live it up for 2 days. Budget of about 2k. I want hott 18-25 yr olds. Independent or at FKK club. Prefer BBBJ and CIM. will have my own hotel. any ideas on agency or good FKK clubs for those who know germany and Berlin well
