Can recommend Sarah who I've seen a few times in the past, left her feedback and field report on the AW site although the field report seems to have disappeared. She does exactly as she says on the tin and the photos are accurate, or were when I last saw her, not seen her in about 12 months now more down to me wanting to sample more of the market and also her reluctance to travel to my place for a 1/2hr meet late at night (as I don't know if my house is free until late due to family turmoil). At £50 for an outcall and particularly if you are in Stockton YOU CAN'T go wrong.
As I'm new to UKP (only tapped in during the last few weeks) it doesn't seem appropriate to do a review on her for meets in excess of 12 months ago but I would say that they would have been positive reviews. She is discrete, was on time, attractive (if her photos are what you like) and certainly provided a service that I couldn't grumble at.
If you book her, enjoy!
