I saw one once, about 2-3 years ago, somewhere between Penzance and Land's End. Was in my local free paper, no photo or description of the lady, or even her age. I only wanted a massage with happy ending though, so her age and looks didn't matter too much. Anyway, phoned her up, asked what the service involved and was told a happy beginning, then a full massage followed by a happy ending. Sounded brilliant, and price was good too (£40 from memory).
Arrived at lady's house and was greeted by someone well into her 60s. Just as well I only wanted a massage and wank. Shown to the massage room which was actually a shed and entailed walking through the garden to get to it. Once in, stripped off and was asked to lie face down. So no happy beginning as promised then. Fortunately I can only cum once in an hour so never complained as I had my happy ending to look forward to, plus her massage was actually very nice.
Anyway, was eventually asked to turn over and she started giving me the most lovely slow, oily wank. She really was good at this and I thought to myself I wouldn't be able to hold out very long. After only a couple minutes though, she asked if I'd finish myself off cos her arm was aching. I told her no, I paid for her to do it. She did about one more minute then stopped again, again saying she couldn't carry on cos of arm ache.
Well pissed off, I got up and started dressing, telling her she was a con artist, basically wanting me to pay her to wank myself off. She was apologetic and said she'd give me a discount in another booking but I told her to shove it, there's no way I'd be coming back. Then left without saying another word.
