Not exactly what you're after, but the closest that I've come across to date.
AdultWorldMedia has
CJWrightXXX.
CJ is a black male with a 'thang' for BBW's. Nearly all of the BBW's on the site are white, but the focus isn't specifically interracial as some of the sets are solo girl and some are girl/girl.
The other 'gotcha' is that promo materials are rather limited.
