As a fellow cuckold I wouldn't do any of those things with your wife. I mean what kind of cuck would I be for my hot wife if I fantasize about or worse performed sexual acts with another woman without her permission.
I would on the other hand congratulate you and support you with those turbulent emotional feelings.
You wife is hot and deserves to have sexual pleasures that you can't or willing to give her. I hope for her sake she finds a good man to satisfy her the way you want her to be.
