Well, well, well - $49.50 for ONE month you may ask?
Yes, and it is worth every fucking cent if you love excellent and uncut Japanese porn.
Caribbeancom is one of the largest single uncut video sites out there. With popular AV movies, as well as exclusive original videos delivered on an (almost) daily basis. It is very popular in Asia and so you can check out the site also in Japanese and Korean if you like. Fortunately, they offer it in English, too. ;)
There are more than 3500 videos available and one is better than the other. They cover many niches: popular stuff like Anal and Lesbian, but also some scenes you won't find easy anywhere else: Kimono, Maid or Cosplay/kosupre - which are always very popular in Asia. They are shot in good quality, but NOT HD and have a lenth from just a few minutes to around 25 minutes. Before signing up, I suggest to check out all their free samples, which are available easily from their menu-tab.
The only downside IMHO is the download limit. With a high price of $49.50, you may at least expect no limits at all, but you are "only" allowed to download up to 4GB. The 15-day trial even only allows you to stream all the titles.
If you are really into Asian porn you will be happy, for people just wanting to take a quick dive into it, may want to pick a cheaper site.
