My wife💯% knows, KNOWS. I want to fuck her sister. She KNOWS, that if I could get away with it I would. Her sister is super cute, and I would risk knocking her up just to bareback it.

I am also pretty sure that at some point my wife has told her sister this, because my wife and I are a little more adventurous in our world, and my sil has told my wife how truly boring her sex life is with her husband. I know they have compared notes, and that my sil would do it, under the right circumstances. However, those circumstances will likely never present themselves. 1. Her husband is a total bad husband. Not a bad person, not a drunk or an abuser, just a doofus, (sports/beer/doofus friends/doesn't pull his domestic weight sometimes) with no real skills and fell into a decent job but will never progress higher. He has given her two kids. So she won't go behind his back and ruin an otherwise ok relationship. 2. My wife wouldn't actually want to know it happened, even if she suspected it at some point. 3. I would totally make a move if we were say, ever alone together for a period of time that we could reasonably be safe. 4. I know, she knows when we visit them. Positive he has no clue.

At least it's a good dream.
