I've slowly found myself liking more of these Japanese "AV models".

But, when I search I bit deeper, everything, almost, is censored/tiled. The models seem to all be FOB (full on bush, full on beaver) and never show pink - despite often doing hardcore tiled porn.

I understand the Japanese have censoring laws, but they do not need to host their material on Japanese sites...

What is going on? Are there any aficiados that have explanations?
