Something to try, severely torture your balls until they are atrophied and soft and I bet your wife won't be able to keep her hands off of them while she's not getting stretch fucked by a huge cock or dildo. She will also love the new taste of your spermless cum from your limp cock. Especially if she has a bad gag reflex like my wife.
And, thanks for being a fan, I hope she enjoys the pictures of my ruined body, too.
