How do you explain to a blonde that a coworker has a wife at home and is a good family man? She just doesn't get it! It is easier to cum in her mouth than to explain it. So his conscience can be calm - he did not cheat, he just bought the girl a cocktail. And he put it in her pussy just to make conversation - fuck me, das ist fantastisch. Let the blonde think it was her charm that worked and make her feel happy.
The housekeeper is so brazen, because she is sure that she will get it all down. And even if she gets it in her mouth, she won't be upset. So the negro put the blonde bitch in the cage, and then got her drunk on sperm - let her remember how to behave in the master's house.
The brunette could not wait to have a new experience with a black man. That's why he did not hesitate to fuck her, just for the sake of it.
