I used to have a vietnamese (like right off the boat, broken english style) fuck buddy about 10 years ago. She was a good looking little gal, although she was highly annoying and completely boring in bed.
Not that I've been with a lot of girls with bad hygiene, but there was something extra special about the snatch on this girl. It had a light baby-powder scent and it actually tasted sweet. I don't know if this is a running thing with asian women, or she was a special case.
