Then you need to check for some specific genres or company. For example there is a video called Sex Masters (I forget which company made it) but the girls act like deviants (think Kelly Wells on speed).

Also check out some of the shit from Giga (good luck holding your stomach). You might run into the occasional "kawaii" behavior but believe me, there will be plenty of girls acting aggressive.

Also check out Yuma Asami. And remember, theres always hentai.
