Dowding - hit it.
The allure of fake boobs is impossible to resist - you just have to know. And like Shatenfries said, you dont want to be 50 sitting at some pub kicking yourself for discussing this issue on an internet BBS when you could be laying pipe instead.
She sounds like a tramp (thats good - disposable women rock) so all you need to do is get your bellybutton over there. Out for a drink or two fine... but dont forget your aim here - hers is probably the same so dont beat around the bush wasting time.
Worse Case Scenario: You get laid, and because you really suck and didnt pull her hair and spank her ass, she never calls you again.
Best Case Scenario: You get laid, she calls you the next day, you get laid, she calls you the next day, you get laid, repeat.
So this is really just about how big you can win. Dont bugger it up Euroman!
EDIT: Oh yeah and uh...
