I believe these are the first Korean videos I have ever seen:
Obviously, the leg/thigh spanking concept is an Asian thing... it's the historical corporal punishment choice in school settings, at home... the second video barely seems like a sexual thing. I actually wonder if it's a real punishment video of a child. But it's probably not.
The first one is unique in that it's 2 Korean women engaging together. Two very big taboos in Asian culture (possible homosexual preferences and S&M). It fascinates me, especially since the top says, "I'm going to give you a couple more so just bear it," and "You have 3 more, just bear it," almost like she's giving her a root canal or something, not a punishment.
