There has been a profile in the NW4 area of a Wild Jessica X where it says £50 an hour, the pics have now gone I see, but there were pics of a right boiler on the profile, and most certainly not a size 6 as the pimp had put, looked like a 16 to me, braindead moron.
Also the location says Willesden, spelt wrongly which is a good few miles from NW4.
Very rare to see an hourly rate under £80 in my area.
