My wife and I have made several attempts over the years to invite non-nudist friends to our resort. Some accepted; and then chickened out at the last minute...
It just never happened.
The closest I've come is when I ran into an old coworker at our resort. I'll skip the details; I've shared them before. But after the initial encounter, we decided to hang out regularly.
My coworker is an "habitual spreader." It's one thing to see someone you've known for years naked; it's another to see their pussy wide open in front of you while chatting about your "shitty old job" lol!
My wife would sometimes try to "match her energy" and be open-legged while hanging out with her. My coworker's husband did not know her from outside the resort; so seeing her bald pussy probably didn't resonate the same as me with my coworker. But it was still nice that he could see my wife the same way I was seeing his - and from the smile on his face it was clear he did enjoy it.
The "benefit" here is that my coworker is an experienced, uninhibited nudist. Things might be different with non-nudists; who might be more "reserved" in their nakedness. My wife has gone to the sauna with some of her friends; so they've all been nude around each other. According to my wife, only one of them was truly uninhibited. The others were very much coy. And it was women-only; which is even "easier."
