I think that it was something to do with a specific back injury as opposed to the general muscle strain that having big tits would bring. We can only hope...
but she will not doing any surgery
it is not that if he has a bad back it must be said that he must have breast surgery
unfortunately she has many health problems
so it is not due to her large breasts
Why can't you save them? Can't you see the "download options" sections? Also, I've heard that Gfycat is a good place to look for short clips.
EDIT: You've likely already seen it, but in the event that you haven't, there's a Mega on the first page of the main thread with a few short Twitch clips.
