I've got ass/anal related sites listed by
anal sponsors and
big butt sponsors where you should find what you are looking for - the thumbs on the left link to program summaries so you can see if they offer FLV's, exclusive content, high res pics, HD videos, etc.
FYI: the site is running a mite slow at the moment, but should be picking up as I do some maintenance. It should stay online provided I don't screw something up.
