I know there are a lot of providers who are afraid of black cock (at least professionally anyway), but there are also bunches of them that don't mind getting reamed at all.
Off of the top of my head, I think Mellissa Madyson is into you guys. I'm pretty sure Bootyful Gia is "brother" friendly, but I'm not totally sure. I'm pretty sure Sknydiva likes black guys too if I recall correctly. Saw a clip she posted a while back and she was getting plowed by a black guy, if I remember correctly. And of course, when Mzluvly comes to town you should call her. Judging from her videos, she's an artist and her medium is black cocks. Chanelofhouston is super hot and slobbers nice on black hogs according to that video I saw of her.
PLENTY of others too, man. It shouldn't be THIS hard to get your dick inside of a white chick, my hobby brother. Good luck.
