Just seen your post, I saw sexy Amy a few years back on a outcall, not bad looking in them days a little hard faced, booked her for an hour, gave me a owo like it was an Olympic sport believe she was trying to make me cum quick, did not give me much time to recover for second round so when I could not get hard she said " well if you can't get hard for round 2 I might as well leave" or something to them words and left after half hour.
This was in my early days of punting and have learnt a lot since then, but personally I would not bother.
