Let my wife have s** with friend
I and my wife's best friend's husband have regular threesomes. All behind my wife's best friend's back.
She has no idea that her husband comes over every Thursday and has rough s** with my wife. He often humiliates and talks bad about his wife while having s** with my wife. It's gotten a little awkward when he tells my wife nasty things he has made his wife do and trying to get my wife to imitate those acts.
