A black man cuckolds me by sleeping with my wife

I've been feeling a bit neglected in my relationship lately, and it turns out my girlfriend has been seeing another guy. To add insult to injury, she brings home a black guy with a huge cock and makes me watch as she sucks his BBC. She then turns around and fucks him doggystyle on our couch while I can only watch. The humiliation is too much to bear, but I can't help but get turned on by the sight of her getting pounded by this huge black cock. After they finish, she comes over to me and gives me a blowjob to make me feel better. The whole experience is both humiliating and arousing, and I can't help but wonder what else my girlfriend is keeping from me.
