You know how much I love this Sara Jean Underwood hottie and I love all the pictures of her I posted on the site, so that even these pictures of her while riding a bicycle shall not be an exception, especially if she decides to do it naked. Here she is on her sweet ten speed for a World Naked Bike Ride piece she did for her nerd TV show G4TV. Though not quite fully exposed, the Playmate turned G4 reporter did take to her two-wheeled machine on the streets of Portland for a glimpse of what a city-wide nekkid bike ride could truly be if only everybody was as hot as Sara Jean Underwood. I wonder where are the pictures of her actually being topless. She couldn’t have ride through a city and miraculously only had pics taken at angles where nothing shows! It’s very weird that she sat on a bicucle in a tiny thong and no one thought to take a pic from the rear…
