I don't think that Anne Heywood was looking for Love with the black janitor but rather she felt a strong need to be fucked by him, she NEEDED his hard black cock fucking in her unprotected white cunt. She accepted his abuse because if she didn't he would not fuck her, when she crawled like a dog as he commanded her to do if she wanted him to fuck her; rather than accepting her as his white fuck toy and cum dump, no more than a piece of white fuck meat; he decided to severely abuse her by burning her big beautiful naked TiTs and nipples. Then he advertised to everyone that she enjoyed being fucked by black guys. That was too much for Anne Heywood to accept so she had to move to another town.
They had a huge sexual attraction for each other, but they were both raised in a racist environment and played their roles. Women were taught not to want sex with a black man, even though it was clear she wanted it.
A black man himself was oppressed all his life, experienced a lot of racism, and tought that white women is not for him, but he wanted a white woman, and when he got the opportunity to make love with a white woman, he did not know how to treat her other than to humiliate her. It was a kind of revenge.
In those days, such stories could not have a happy ending.
They both were victims of society rasicism.
