From what I've seen and experienced, a girl is not fully blacked until complete dominance over her is established. This can include making her do sex acts she wouldn't do otherwise and only does so because he's black. This includes anal and sharing her with his black friends as well as other things. This seems to be especially true with black men who want to establish their alpha male status and domination over a white husband by making her do things she never has for her hubby. She has to be willing to participate in this and does because he's black.
