well, to be clear, it's not a "giggle" like tee hee hee. it's like a coyish childlike. like they're new to the biz. in any case a marked difference from the korean this is what we do and we know how to do it - hot sex know it all,,,,, and the japanese reserved polite geisha-ness.
it's a difference relative to the other two is what I mean, so dont take me literally. I should have been clearer but I couldn't pinpoint it
