Vivid - Some more hardercore than others

Wicked - Some more hardercore than others

Private - Harder core, with more anal and group scenes. Look for their Black Label, Private Gold, Private Penthouse, and Private Films lines which are all storyline based. These are european so you have to be able to get along with some dubbing. Start with their earlier movies Tatiana I-III, Pyramid, etc.

Unfortunately none of these are on your sites but they generally have sites of their own. I would recommend BushDVD to rent them.
