I saw British Beauty last week. She is slim, though not skinny, and has big boobs. Very pretty face as well. I thought she was gorgeous and would appeal to most guys. Seemed like a nice friendly lady as well.
She definitely does CIM. She advertises anal in her enjoys list so you could email her and ask how likely she is to agree to it and how much extra she would charge (if anything).
Sorry, but I haven't seen any of the others.
