Chelsea has a camera and this is her angle whilst filming down so your kind of getting her POV view, Chelsea sits all over her slaves face smothering him in the crotch of her knickers he is really struggling to breathe down there here you see as she films the action from her POV angle, the ass smothering is not captured in this because Chelsea struggled to film it therefore the clip is of a smaller file size and also cheaper. (Clip is 2:23)
