Or search for "tekoki" (study of man's penis) like Soft on Demand's 100 Girls... something. It is censored, and we all prefer uncensored, but 99% of Japanese stuff - unfortunately - happens to be censored...
Only thing I really like about JAV is the blowjob scenes. Shame they're usually over in a few seconds. Try "yellows 2007" I got the torrent here once, it was really good but it only got to about 97%, so you might not get anything at all now
