About a month ago, I bought my wife two dresses. The catch was that she would go out twice in April without panties. My wife doesn't really like going out without panties but it's one of my biggest turn ons.
So the first was a party with friends. Because she was afraid our friends would notice the absence of panty lines. I thought it was insanely hot because we were the only ones who knew.
The second party was twice the fun. It was a party for a couple who recently had a baby. The innocent setting, knowing that my wife wasn't wearing panties, a little alcohol, a lot of squeezes of her butt, feeling no panties.
The second fun part came when we left. We passed a park on the way back home and stopped to take a little walk. That's where these pictures were taken.
