Is there a club available where the girls are available afterwards?
Probably most if you approach the subject with discretion.
A. If you fancy fucking the girl - you will probably have spent £££ on her already, and
B. ON MORE THAN ONE VISIT! so, you have some degree of recognition / trust established with her
C. she will have exchanged phone number and will have you on her VIP list
D. have circa £500 (or more) cash left for a couple of hours and more for the overnight
E. she will have to like you too!!
I use 2 venues in London and have one girl in each who does the business.
