I don't know. She probably would charge a black guy a LOT more money to fuck her than if a white guy made an offer to do the same.
What if you try to fuck her for free? She might not want to. But if a white man tried to get in her pants for free, she wouldn't think much of it and give him the time of his life. Besides, biracial people are viewed more favorably than someone who's 100% black, so she might let those guys slip through the crack. But for a man who's all black, she'll give you the "let's just be friends" speech.
It doesn't matter? I don't know if the majority of black man would agree with that. If she really thinks black men as extremely unpleasant, nasty, repulsive, then how do you expect them to be just fine with that and not look at her any differently?
