I rarely find myself venturing in this part of the forum, but when I saw the headline of the thread I had to impose.
I have found the same: British women are well-endowed as a rule. My first "bird" was bodacious, and her accent knocked me out. I thought it was a coincidence when I "ran" into another Brit with tremendous assets.
As I've mentioned before, my wife would fit right into the country, that is if she never opened her mouth. So when I met her mother I couldn't believe it. Her mother is straight from Blackpool! And she, too, is stacked. I mentioned this to my wife as innocent as I could, since I had only just met her a few months before, how I wondered if British rearing had something to do with enhanced mammaries. She told me her grandmother, still in England, is even bigger than mum and herself.
A blest family.
