A woman's slit is normally closed, so at a nudist park a woman doesn't really offer a view of the pink inside. But...

A few years ago we were in a clothing-optional setting, and there were two shy young men there who kept their swim trunks on. I was dozing off on a recliner next to my GF, when in my half-sleep I heard her talking with the two young blokes, who were seated or kneeling in front of her recliner. I looked over, to see that she had lifted her sundress up over her waist, with legs stretched apart over the armrests. She had removed her knickers and was giving the two fellows a guided tour of her clit and the moist pink flesh of the folds of her inner labia--that's just about as exposed as a woman can get!! Turns out that on the day before, she had heard from some other women that these guys were sexually inexperienced, so GF made it her personal mission to educate them. She shaved clean that morning to afford a clearer view, and when the fellows appeared she called them over for their 'lesson'. I heard her tell them they could look but no touching, while she held herself wide open for perhaps twenty or so minutes.

Here's a video capture (GIF, so click on it), taken by one of the other guests at the nudist park. It is GF's actual pussy at the described event, not one grabbed from the internet.

(A few days later we found out from one of the unattached women that one of the two fellows used his newfound knowledge on her, to her great satisfaction. Then, a couple of days after that, one of the married women furtively reported the same thing.)
