About time for a threesum
My wife sister has black husband I knew that years ago my wife had fucked this guy too, I was wanting to see my wife do this again, she was was very opposed to the idea saying that it would ruin things between us, but I talked to my sister inlaws husband, he was very willing and knew it would take some planning to make this happen, we knew that we would have to get her somewhere we would be able to fuck and have my wife pretty drunk, her sister helped set this up, found out later that my wife and her sister had been talking about this before, we put this together being at our house and my sister in law not being able to be there, it seemed very strange at first but quickly became what I hoped it would be, I just watched, jerked off my wife and I never talked about what had happened unless we were fucking and she was drunk, we have since done this about one time every 2 months, no regrets.

You wanted it. Your brother in law wanted it. Your wife wanted it. Your sister in law wanted it. Sounds like everyone got what they wanted.
I guess the question is who is going to be in the 3sum? Obviously your brother in law, your wife but who is the third?
