I watched my ex-wife going from "reluctant nudist" to "hedonist."
It was a very slow start. Wearing sarongs at the club/resort, "hiding" in the back of the pool area when sunbathing nude and keeping her legs crossed, etc...
Then one day, about two years into it, she was "convinced" by other women at the club to take off her sarong. And everyone seeing her naked - and responding favorably to it - "triggered" something in her.
She stopped wearing sarongs, opting to be completely naked all the time. She no longer "hid" in the back of the pool area, and started lounging at the front of the pool.
Then, she started shaving. And lounging with her legs open. Even while socializing. She became very popular at out resort.
During that time we had started making nudist friends. And she would give them the "full-body" hug.
On trips to and from the resort, she started just wearing a sarong; and taking it off on the way. Riding naked; and at least on one occasion, also masturbating on the way home.
Flirting with our nudist friends increased; along with physical contact. There would sometimes be "wandering hands" (and not just from men), and she would lean into it. At least on one occasion, she let a friend give her a full-back massage; and I watched in amazement as his hands lingered on her ass, with no pushback from her. She gave that same friend a "tit-hug", playfully pressing her big tits against his face. Things were escalating.
And then she started scaling back. She had been experimenting, "testing" the effect she could have on other people after realizing they actually liked seeing her naked. "Spicing up" her social nudist experience. But then she realized that she was at a point where she could not go any further without things really getting sexual.
That was a crazy time though of seeing my wife getting progressively "wilder."
