He's doing what every black man does. Whether a white wife is 25 with a perfect body or 45 with some extra pounds as with this wife, if she wants him to breed her, he's all in. A black man's first choice to breed is a white wife, what isn't talked about as much is how these white wives eagerly want to be black bred. It's a fantasy of theirs if he leaves behind after their sex a beautiful "black bun in the oven." After all, interracial sex is for making black babies! Good time by both!
Not always easy to get fucked in the ass by a black man because of the size of his cock. But, with practice and plenty of lube, that too can be accomplished.
