Soliciting advice on moving fantasy to reality... ? [I Sharing The Wife]

Mine started with my wife being seduced by here boss! They fucked after a party where my wife stayed to help clean up! I knew immediately when. She got home I could see it on. Her face! She approached me and went to her knees pulled out my cock sucked it for a few min then said fuck me now! Her pussy was so stretched and full of cum it was unreal!
Of course I was so pissed but the thought of it excited me so much it was crazy! It has continued until several years ago with five different long term boyfriends.
