Hot wife

Well, first of all, I don't know what you think a cuckold is... but a cuckold is a man whose wife has sex with other men. You said your wife has been taking a strange cock every now and then over the past 10 years. So you're already a cuckold, which I suspect you know because you're posting here on a cuckold website.

Why your sex life got sidetracked is the mystery. Personally, I find it difficult to believe that your wife showed her family the YouCuck website. Sitting down with Mom and Dad and showing them cuck vids that she and her husband enjoy together just sounds preposterous to me.
cuckold - Pronunciation - kuk-uhld - noun 1) The husband of an unfaithful wife. 2) A husband whose wife has sex with others. NOTE - It does NOT say: Sexually confused, submissive, humiliated, sissified, crossdresser, cocksucker, or piss drinker

I think it's already too late - you've lost her, to her brother!!

Think this falls under "be careful what you wish for"..You do know that denial can be part of the cuckold experience!!!!
