Sharing

So just wondering if I am the only one or if it is normal to want to share your wife or s/o with another guy? So the thought of fucking my wife in the ass while someone is ducking her pussy just does it for me!! Hell I am a voyeur. I would t mind watching a couple of guys do her. Her and her friends joke about her messing around I said as long as I get video!!! I don’t think she believes me!!
