You beat me to it - and frankly expressed it a lot better than I would have!!
I agree with all that RK had to say on the subject and about the WG as I made the same error in booking the WG in May this year.
I estimate the WG is 64 yo and suffering from Parkinsons, she told me that she was suffering from Parkinson disease. I can't say how advanced her condition is but her right arm was shaking well enough to give me a good hand job I thought.
She also needs to work on her bush hygiene as it is urine wiffy. She's a squirter (which means to me she pisses when she orgasms) which she did during our encounter, squirt that is.
Looks wise, imagine old lady with no lips and grey hair upstairs and downstairs, yep a dark grey and silver bush - a used Brillo pad.
Still I tupped it as it was raining quite heavily and didn't fancy leaving immediately as I had a long way to travel and stopped off for the meet on my way home. I had a hot shower before I left and felt quite relaxed. For me you pays your money and takes your chances that you're going to enjoy the experience.
I can't recommend this WG though.
