How to I convince my wife to be with another man?

We had a male friend who had gone thru a divorce come over to cook us dinner. After dinner and drinks I said out loud that we can't send him home all horny. Honey you should give him a blowjob for the road. It worked. For a few years he would come over and eat and drink with us, then fuck her before he left. Then her and I would fuck like bunnies. Try it. it worked for us.
