This interracial sex looks very harmonious. The Negro girlfriends are already trained for a threesome, and he doesn't have to teach them anymore. While he's doing one, she's rubbing the other one's pussy so she doesn't get too relaxed, and they all work together like clockwork.
Those who think it's not normal, think about it, these are strangers to each other. That's why there's nothing wrong with it. Two adults of different sexes are at home alone, hormones are splashing in both of them. So the skinny blonde was not at all against caresses from her stepbrother, she only broke down for show, but with his insistence his brother showed the seriousness of his intentions, and that this will not go beyond their bedroom. Both are happy at the end!
