Those are pretty good, aside from the mosaic censors, squeaky yelping and the 'oww this hurts' fake looks of pain. Some of the first porn vids i actually watched are JAV and those three things always did annoy me (censor/yelping/ouchie). Would you happen to know if that site has an english translation? i wanna browse around it look at the stuff you linked, maybe even see if i can find some uncensored JAV stuff.
Thanks for the tip about Chrome, i'll have to check that out. I was thinking about running the site through babelfish translator or something but i'm guessing that Chrome is better. I will also check out that video...the preview clips look pretty good.
