I always imagine it the other way. That I am being cuckolded by a sexually repressed Muslim bully (I know it's not politically correct but most times in my mind he's from the middle east, sometimes Africa). He's a recent transplant to the Us in our area who's path had somehow fatefully crossed ours. Meeting myself and my white, western wife he decides he wants what he sees enough that he works his way into our lives, befriending us with no other purpose except to get his hands on my wife.
Acting with cocky confidence he quickly subdues us. In no time at all he had conquered me, making me spill my fantasies of my wife with other men and uses them to render me harmless, useless as he uses my lust against me. Getting the green light from me to seduce my wife. Before long with the pointers I had foolishly given him he has worked her submissive side, leading to her quick seduction.
Once he has her in her grip he turns up the heat. Visiting her at my home during the day while I'm at work. Using her harder and dirtier each time he comes over. Gradually she surrenders more of herself to his reconditioning. Putting her in her place as his submissive sexual servant and reaffirming it with punishment and hardcore action. Soon I am his cuckolded fool while he and all his friends just like him use this stupid infidels precious wife for their sexual amusement. Treating her the way you imagine they would if they had control of what they considered a dirty godless pig and doing it all day long. Now it's starting to happen at night too. He or any number of his friends will barge in on us and demand their rightful use of my wife as Muslims and drag her off to my bedroom and make her submit to them. Oh, what a horrible life? ;-)
