||This is a pretty good site. It features a lot of interracial sex, but is also includes some black on black scenes, too. The archive is very large, even though many of the videos are lower quality. I like the fact that it is still actively updating with new, high quality scenes.
If there is one knock against the videos at Racks & Blacks, it might be that there are too many "typical" pornstars. I'm talking about big boobs, blonde (usually bleached), white chicks. I'm not complaining, but some might find the lack of variety to be a negative.
All in all, I enjoyed this site. I wish that if offered a bit more variety, but I liked what they have. As with all sites in Brazzer's Pass, there is a slight navigation quirk in Firefox, but that's not a big deal. I guess the only 2 things that could improve this site are: 1) make the older videos available at higher resolution and 2) add a few more anal scenes for those big black cocks.
