Wear leggings and a T-shirt with your hands tied behind your back.
Start the clips standing up with your hands tied behind your back, Then try to hop around, fall over onto the ground and try to stand back up. As you do this your leggings fall further and further down and you try to pull them up to stop exposing your butt.
The view so that it was an ass to the camera, so that I could see how your buttocks are exposed.
