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.
Man is old and fat, it's hard for him to cope with such a temperamental beastie! I think she always has a couple of young guys to help her out. So grandpa probably has antlers like a reindeer!
