Teen friends competing with too short shorts

While I'm following these two teenage girls, I feel like I'm watching them compete on which one of them will wear shorter booty shorts. There is a significant amount of ass visible on both of them and the girl walking on the right side is even trying to tug her shorts out of her ass crack a bit, to release the wedgie. Almost as if some part of her subconscious mind is telling her that she is showing too much of her naked ass.
