I have seen Sasha, Eve and then Lauren twice, and I thought Sasha and Lauren were both very good.
My particular kink is sounding, which Eve is not wild about, so that was just a case of differences between us.
My first visit was with Sasha and I asked her to talk me through some of the other stuff that I tried that was new to me, and she was very good. This visit was a 2-3 years ago.
Lauren I really enjoyed seeing because she seemed happier to be rougher where she was sure I could take it. Also when I saw her, they had some larger sounding equipment, because the first kit they had wasn't big enough for me.
Sasha had made up for it by sticking her little finger down my knob-end which was great. But Lauren really went to town on me with the sounding kit and the strapon.
Anyway, I am explaining like this because I could see that there were reasons that affected my enjoyment that were partly outside the immediate control of the SP (equipment) and also some matters of personal taste. I was happy with all of them, but most want to see Lauren and Sasha again.
