I remember reading a hooker's autobiography, who claimed she'd started boning one of her clients outside of hours, her logical being his boss had bought him the punt so it wasn't like he was paying her originally, and that he was hot and rich. Plus US escort/blogger Maggie McNeill was also married to one of her clients for a good wee while, before deciding she preferred muff diving again.
In my own time, I've long stopped bothering to count how many escorts I've been with (over 100 for sure, possibly still less than 200?), and in a handful (literally less than five) of cases, usually someone I've been seeing for a wee while, but also two where a toy was used, I've had an SP claim she came. The only one I'm sure of was the squirter with the dildo, but isn't that always the case? Sadly as men, women generally have us over a biological barrel when it comes to the bedroom. In no cases did climaxing exempt me from coughing up for a booking first lol.
I did once win a competition and shag a MILF for free, but between the cost of the hotel and the train over, I should have saved my money and gone punting in London
So yeah, SPs are human and can occasionally be attracted to their clients, but if you think this is going to change the nature of your relationship with them (at least if they've got any sense) you're going to be disappointed. One cheeky WG I knew asked if I'd be interested in doing some POV porn with her for her to post of Adultwork and then tried to charge me for it like a punt! At the end of the day, whatever their pussy feels for you, sex is what puts a roof over their head and food on the table for the vast majority. Ask yourself if you would throw away your job because you fancied someone at work...
