I can fully understand the point of a working lady trying to make your punt as enjoyable as she can. No doubt that is her job and many here would enjoy the experience of being treated 'like a king' or 'a stud' during their punt, I know I would. However, I generally don't like it when they are faking orgasms. Realistically, I know I can't make them horny / make them cum and that I would only be wasting my precious time if I tried. Nowadays, I am more of the opinion like how another punter has posted above; I pay them to make me cum as much as they can. I'd rather if they did their job to get me horny and then lay there silently for me to finish my business than to fake that they are enjoying my company (which I'm pretty certain they're not). I've even once told a girl to 'shut up' mid-way during sex as her moans/screams were actually rather off putting.
There has only been one instance in my punting career where I am pretty certain I made the working lady orgasm during the punt. Many years ago I punted with a so-called 'high class' London escort who charged £350 p/h (yes, shoot me down I'm a mug, etc, etc. Though it was well before the knowledgeable UK Punting site existed). Anyway, I suspect the reason why she did orgasm with me was because she was not very well advertised and therefore well 'underused' at that time (so to speak). Very nice experience, but not worth £350.
