I'm not a regular punter; I've been seeing one girl not a service provider regularly for a few years now on a Sugar Daddy basis.
However I did meet Camille St Clair, you'll find her on Twitter. She is ex Agency Allure, now independent with good reviews on here. English, mid 30's but could easily pass 20's, has a nice incall apartment in Battersea, good company and very, very naughty. She is around £500/h, but only sees one client/day so need to advance book. She is athletic but very slim, no boobs whatsoever.
If you click she is fun, but as others have said, you might be better off with a few £200 - £300 punts to start out; it's your money, so your choice.
