Well, someone HAD asked how she does it, but the comment seems to have disappeared. I was just trying to be helpful. No need to be condescending for no reason.
How does she do it? Well, in quite a few of her videos she very obviously is doing "poppers" (a liquid inhalent that causes a certain type of heavy muscle relaxation) and could quite possibly have used other substances to keep her relaxed and horny as fuck. You won't find many people taking these huge toys up their asses without at least using poppers.
