Hmmm, doesn't look like her so much, don't know
Well,
@quansz already answered, and yes, it is her. You can see the pokemon tattoo on her right hip and the wart(?) on her left shoulder. In case you know (a little) about avisynth, here is a 'pornstar edit' for Kate Black (2) in phgc17, using the same source files the joined (without trims) video should be 264883 frames, 2h, 56min, 35.32s long:
file1 = LWLibavVideoSource("YourPathTo_pt1_main.mp4")
file2 = LWLibavVideoSource("YourPathTo_pt2_main.mp4")
file3 = LWLibavVideoSource("YourPathTo_pt3_main.mp4")
file4 = LWLibavVideoSource("YourPathTo_pt4_main.mp4")
file5 = LWLibavVideoSource("YourPathTo_pt5_main.mp4")
file6 = LWLibavVideoSource("YourPathTo_pt6_main.mp4")

Prefetch(4) #cores to use MUST BE END OF SCRIPT
Example works using avisynth+ 64bit and obviously using LWLibavVideoSource instead of directshowsource. This .avs file (it is just a .txt with renamed extension) can be played by many players like MPC-HC or Zoom Player, like a 'real' video, just initial loading takes forever! No sound in this example script, it is intentional!
