That is the way of the dominant black alpha. He will dominate the wife and then the husband. BOTH will submit to his domiance. That is what happened to us. (wife and I). I became addicted to his cock as much as she did. I wrote some stories about it on my profile.
Wife tells cuckold husband: "You make sure you please our bull and you MAKE sure he's happy. I don't want to lose that black stud. You hear me? DO whatever he wants.. ANYTHING. I don't care if he makes you lick his butthole. YOU DO IT. "
