She is indeed, and I've seen a few of her videos over the years.
Without wishing to be too harsh I think you could definitely add at least 10yrs to her stated age of 42, but so long as the pictures show what you actually get, and she still provides a good service, why not?
She doesn't show a 30min rate on her profile and I think £200 is rather a lot for an hour, but £120 for what the OP received is pretty good value IMO.
