Like winning the euro millions I guess
I can think of a bunch of things that could ruin this or you will find that when you do it , it wont be as exciting as you had hoped
Choice of escort for starters. Im sure there are great ones out there but you still get the ones who want your money and just do a job. In your fantasy I bet shes gagging for it, everything is in slow motion and soft focus, roaring fireplace, smooth jazz on the stereo (or drum n bass if you prefer) a chilled Bollinger by the bed side
Yes, the reality is not quite the same. It could be with a girl on a grotty floor in a housing estate and a chav boyfriend wanting the money to buy drugs shouting directions "Yeah mate go on fack er! Shes a skank and looooves it up the pooper! Dontcha Beryl? Cos youre a slaaag" (Hmm sounds like a god one for Real Couples)

Let us know how you get on though. I dont mind being proved wrong
