Ann and Winky are my 2 favs but different experiences.
Ann - Incredible teasing from the get go, especially if you are responsive. If you like a little prostate play (nothing to hard core - not that there is anything wrong with that), even better. I have said in my reviews that it's like she wrote the manual on Lingam massage by the way she treats you, but she knows nothing about that concept. She's a natural.
Winky - If you want a body slide experience that is out of this world, see her. It is as close to FS without actually going there. I am really into senual play and simulated sex and Winky is the best I have been to. I was experiencing sensations I have never felt before and had to look down to see what she was doing. Wow.
