Going back to the original question, pussy licking is certainly more common for me than it was when I first started punting, almost fifty years ago. I have always used mostly massage parlours for my punts, and for several years I was neither offered, nor asked for, pussy licking. In the 80s, I nearly always used the legenddary Josephine Daly's establishments, and got to know several of the girls really well. A few of them were happy with my technique of using a piece of clingfilm over the pussy, and seemed to enjoy it. I don't remember having to pay anything extra. After some time, I was allowed to lick pussies wiothout the clingfilm, and used a slug of whiskey from a hipflask as a mouthwash before and after. There were always several girls to choose from, and I got a bit of a reputation, so if I asked 'who would like to massage me, I often got more than one offer! Those were the days.
Fast forward to the present time, and many girls in massage parlours offer, or can be persuaded to offer, pussy licking. During my most recent punt, after several recent failed attempts by the girls to 'get me over the line', I asked my masseuse if she would like me to lick her pussy. I was surprised when she agreed, and didn't ask for any more money. I had paid for a naked b2b massage. The resulting 69 quickly brought me to my best finish for ages! There's life in the old dog yet!
