My wife has done and continues to do similar to this both when I'm at work and other times while she leaves me upstairs on our bed wanking while I listen to the sound of her getting what she needs from a big thick dick downstairs. She loves it too!
When I used my married friend like that years ago, she would say "Watch the windows and doors cause he might come home without calling. That was a distraction.
What a beautiful vid. They were both getting exactly what they craved and needed. All white wives should have a Big Black Cock to service and pleasure behind hubby's back. It will keep them happy and satisfied like no white cock can.
