One more thing, they may be talking about Korean inexperienced porn, but they're speaking Japanese in the video.
I found the file
here and while I only know a few words of Japanese and no Korean, I know enough to tell them apart.
If you download the linked file it will contain two video files, one complete one and one that has most of it missing because this is rar 1 of 3. However, the complete file is the video we're talking about so you don't need rar 2 and 3. It is about 50 minutes long, but it didn't help me to actually identify the woman. Uncensored JAV is always trickier than the censored stuff.
