Your neighbors wife is NOT your girl. Don't wanna share her with her husband? Too bad. You telling me you wouldn't fuck your neighbors hot wife for real if you couldn't "steal" her from him? Get a life kid, these are just games here.
She literally stops having sex with him and says she will divorce him to become yours exclusively.
You tell her NOT to do that, that you want to instead sharing her with him.
I don't get why you are lying about this and insisting on it being hidden.
You seem to be extremely ashamed of your fetish to the point where you want to pretend it doesn't exist. but it does exist and it needs to be tagged.
Tags allow people to find fetishes they like, and avoid fetishes they dislike.
