I have a couple of thoughts on this thread:
First, ass to mouth is icky and most anyone would stop and pause on kissing after a rim, until the little head takes over and rational thoughts go out the window. So I don't judge.
Second, there's some pretty misogynist stuff being posted here that I find uncool. We should do better and maybe we'll be rewarded with good karma in our exploits.
Third, obviously these girls are in it for the bucks and probably wouldn't do it otherwise, but of they chose this profession they are probably at least okay with it. That said, there's a whole spectrum of enjoyment that depends on how a guy looks, smells and behaves, and many will clearly enjoy a session with a guy that they like more than one they can't wait to get out the door. Ever work in a client facing role? Obviously you prefer clients that are easy to deal with and have rapport with. Well, they're in the ultimate client facing job. I know from decades of experience when a girl is having some fun and is happy to see me come back, and it isn't all about $ because I don't overtip, other than an occasional extra 20. Look, I have no illusions, this is business, but business is best when it's fun. Common sense.
Lastly on Selina...I agree that she is very hot, esp by amp standards. I also agree that the only negative is the mm bs because, while they look ok, they don't feel natural. But that's the only negative and it really didn't bother me at all. But her English and personality are good and so is her service. She will be a repeat for me.
