Look mate. I can see looking at your previous posts that your dying to smash a porn star. If it's just about ticking the box, and you've got the money, why not book one in London? I'm sure there are other fantasy punts out there which don't require you to either get on a plane or put down a ridiculous deposit.
A 12 h booking is crazy anyway, especially with a completely unknown quantity, you will run out of spunk after about 2hrs, realise what you are spending on another 10hrs conversation and want to cancel.
You sound like a young lad. You will probably go on pornhub tonight, see a stunner and by tomorrow want to start a thread on her as well
. Honestly mate, take it from us, this a bad idea. But if you're going to do it regardless, then just crack on and write a review when your done.
