Love this video. I've done the very similar thing before on the streets late at night in a neighborhood and apartment complex near where I live. It is truly exhilarating to do, especially when you are completely out in the open or under street light. You can see how starts getting into it during the walk when she raises her hand in the air, kind of a nervous, erotic energy from being nude and exposed. At least that is my interpretation from my similar experience.
Comme c'est beau une femme qui se promène ainsi totalement nue dans la rue la nuit! How beautiful a woman who walks completely naked in the street at night!
I've done this more than 100 times since 1999. One night I went for a 1 1/2 hour walk on the west side of Central Park in NYC. Saw a number of people, but since it was 3 am in the big city most people didn't really care.
