Whatever the female equivalent of a donkey walloper is I would think could serve as a bench mark. Less face it their male equivalent would be too dim to be much use to the assorted posh totty!
As would I. As for whether Posh Birds are better it is difficult call - wantonness and sexual ability/capability are not necessarily a reflection of upbringing, unless of course you went to a convent school and feel either guilty and therefore won't do it or believe you missed out when younger and have transmogriphied into a belt-fed Wombat!
i think posh birds are no better really its just the thought of them doing dirty things to you cos they seem "forbidden fruit?"
my two experiences of posh birds were at henley royal regatta where i was security and another memorable one was a brigadiers daughter from wilton that was a very dirty young lady indeed. she broke my bed in fact with her bedroom antics. pure filth, with a posh accent shouting obscene words thoughout the sordid act!
she even laughed the next day where i told her, "tell daddy you were shagging a Cpl last night"
I think they are, my first venture up the poop-chute was with a bird that I met in a bar in Edinburgh, she sounded like Princess Fergie and was a dirty whore, I'm getting strangely aroused thinking about it, back in a minute.
