I've been trying to track down this webm for months now with nothing but a thumbnail from the archives to show for my efforts. Someone was kind enough to enhance it for me, so hopefully that helps. If you could PLEASE check your folder(s) for this video, I would be absolutely eternally grateful. This is my white whale, my everything. If it helps, the name of the file that I found it under was "hm white hj" and the girl's name is Hailey.
Also, this one is of the same girl that I'm looking for.
