There Is A Slutty Side Deep Down

My wife (39) is soft spoken, quite shy, and usually dresses very conservative. But shes got a cute face, fairly average mom bod, some saggy C cup tits, and a nice bouncy ass.
We went on an extended road trip across half the country early this summer, first time without kids and I accidentally awoke a little sluttiness in her. We were set up in a koa rv park a couple of nights in and began to fool around. We had the curtain pulled between the camper and cab and I convinced her there was no need to get dressed afterwards. We had a lot of just barely R rated fun that night.
Next night, a bit more secluded lake side lot, and I opened the curtain just a bit. That little "what if someone sees me" had her nervous but turned on. Middle of the night I had the curtain all the way open. There was no one around but the thought of her being caught made her very horny.
Things escalated bit by bit over the next few days and nights, then we found ourselves driving through Nevada with her butt naked in the passenger seat. For the first while she would duck as trucks and cars went by, then she loosened up and sat with her tits in plain view. I was catching glimpses of eyes bulging in the few seconds oncoming drivers could spot her.
Next thing we did in Nevada was swap out her mom swim suit for a very revealing two piece. Again she started out nervous, wearing a small shear cloth around her waist. After seeing some other women in revealing bikinis she lost that. Seeing my wife's nearly bare ass shake with every step out in public was a hell of turn on. She even had the slightest amount of pussy lip visible from behind if her legs were open at all.
Next stop was Utah and our camp site was emtpy. She went completely nude and even walked away from the rv a few times. I dared her to go farther but about 100 yards was the furthest she was willing to go. Got some great videos of her though and the sex was the best we've had since we first hooked up nearly 16 years ago.
We are going a couple of shorter trips before summer is over and I'm going to surprise her with a nude beach visit and see if she's willing. She is excited and talks about getting naked in public very often now. We have gone out on a few date nights since our trip and she has gone braless and pantiless, even wearing nothing but a low cut sun dress on our dinner and movie night last weekend.
Becoming empty nesters is shaping up to be really fun!
