I would highly suggest Pornstar Super Heroes from Elegant Angel:

I would also suggest checking out Jonni Darrko titles from Evil angel, specifically:
G is for Gianna
Trophy Whores
The Angels of Debauchery series
Several Jules Jordan Video Titles fit the bill as well:

If you want more BDSM "dark" stuff try Jake Malone from Evil Angel as well and their is always the Kink.com stuff which is fantastic.
