Hope I don't sound like I am on commission for them as I frequently recommend them but Cheshire Companions would be my suggestion.
Not all the ladies are great (I need to do a review of Libby which will be Negative) but Ava, Lucy, Geri, Holly and Monika would all get strong recommends from me.
£260 for two hours.
In terms of skinny girls Jennifer and Taylor look tasty but I haven't tried them.
