A few years back my wife and I were at an adults-only nudist BnB. We were up very late, getting tipsy and playing pool naked with another couple. The guy got rock hard. My wife didn't show any concern about it; and it certainly didn't deter her from leaning over the pool table to take her shots, exposing her ass and pussy from behind. It would have been easy to invite him to stick his hard cock into my wife while bent over (assuming his GF was consenting).

But...nah. We draw the line at "looking." She knows I enjoy seeing her exposed naked in front of other people; and she makes secret of the fact she also looks at cocks; and even finds some "attractive."
Would there ever be a situation where that ever happened? I'd say "never say never"; but it would take a pretty unlikely set of circumstances where I'd be comfortable - and she'd be willing - to her being groped, fondled and then penetrated by a fellow nudist. We would need to have a very strong connection - and attraction. And tbh, if some other nudist has his dick in my wife; I'm putting mine in his'. So I'd be more amenable to a "swinging" situation rather than a "cuckhold" one.
