Me thinks a dumb American got Austrian confused with Australian! Happens all the time LOL! There was an Austrian guy in my class at college who had a t-shirt saying "Austria... we DON'T have kangaroos!"
As some people in the thread on youporn pointed out it's not a real Dutch prostitute because they're not using condoms. They may be amatuers or pros who rented the use of a genuine Amsterdam "window" and room to make their porn.
Nevertheless, it's a pretty good video. Not the best but pretty good.
