I have done the payments afterwards with two WG's. It did surprise me a bit thinking about it afterwards. I always thought that you have to pay a prossie beforehand or they'd get angry with you and not even let you touch them. But both are very well reviewed girls who obviously must get a lot of business and regulars, so I just took it like they are used to seeing regulars and leaving the payment until afterwards and I just got the same treatment that they probably give to most punters. The service was very good from both of them, but again, I just looked at it like, they are both experienced prossies that know what they are doing and are confident in it, and that they are like that with the majority of punters that come through their door.
It was a nice touch in a way, but not a specific thing I was looking for or expecting. I'm always happy to pay at the start of the punt. In fact, I quite enjoy the payment part and looking at the WG as she takes the money. It's always entertaining for me, and often quite a turn on. I remember one Polish WG standing in front of me in her stockings, high heels, knickers and bra, counting out the notes individually, looking excited whilst posing in a really sexy way, fucking hell, it really turned me on.
It was then followed by a very exciting dirty fuck.
