Want a hot wife ./wantahotwife

Been married for a long time, it's always been my fantasy for my wife to have lovers/bulls/stags and for me to see her being fucked/used. She knows my fantasy but doesn't want to go that route, the nearest we have got is her showing her hard nipples to another man,I used to consider getting her drunk and letting someone fuck her but my aim is to see her enjoying fucking others and wanting to do it, any others feel like this? If she became a slut I would be happy
