Split tongue will never be popular just like tattoos aren't basically because it goes against japanese culture, this doesn't mean that from time to time you won't see girls with some but it's not the norm or common
.
Compare western porn against Asian porn:
Western = 80% of the girls have some tattoo or piercing.
Asian= 10% of the girls have a tattoo, same as piercing.
And this is why I love JAV, the girls remain "pure" at least they are on the scenes I watch, maybe mentally they are broken and very filthy, but I dont care xD
i also hate tattoos on the girls, I like to see their bodies as they are and not all full of things on them, semen is fine
I think he's just enjoying himself to be honest, and why not, eh?
it's all fine but he is not there to enjoy himself or talk, just direct the scenes... it's annoying as hell, at least it is for me. Can't hear the sounds she makes or anything really just him talking over and over.
