I too have seen Katie in the past. The first time was when she first started and she walked me to the summer house, lovely private secluded small pond and summer house, sun was shining and it was like being young again having sex outdoors. Saw her once more in the summer house and once in my car.
Like everyone else her timings are awful at best, if you book for 11, turn up at 11.45 and you won't have to wait long. And yes she is scatty and nutty as a fruit cake! But having said all that she does have something, she is fairly good at oral and is happy to do most things without question.
