She gives what looks like her real name via her email address. I’m not stalkery enough to a google her, but I’d imagine that it’d put her in the 50-59 group. Probably
What, you mean her actual real name is Mature Surrey-Escort? (
[email protected]). I wonder if people call her Matty for short?
Well at least you can say you fucked a posh bird, she's got a double-barrelled surname

Regarding age, I'd say she has to be at least mid-50s, and that's assuming her pics are current.
