We are a bit older than you but I took my wife to a swinger party and a man kissed her on the neck and convinced her to go to a bedroom with him. I love watching and this got her into the scene and she didnt look back.
We attend a monthly party for older couples at a private house. My wife is 60 and is greatly popular with young black servicemen from a nearby military base.
We have never had one that was bothered by our cuckold antics.
