I recently watched the Korean movie
Thirst.
It's by the same director who did Old Boy (which I know some of you have seen, and every single one of you should, seriously fucking awesome movie). As a matter of fact, let's take a short break to watch one of the best scenes in that movie:
Anyways, same director, and it's about a priest who becomes a vampire. It's a pretty decent vampire movie, I know there's been a lot lately, but It really doesn't focus on it a whole lot. He gets "taken in" by a family from his youth and gets involved with this other guys wife, and it basically get superfucked from there. It's an even mix between American Psycho and a porno. There is a lot of sex in the film, and it stars this hot little bitch:
And she gets naked often, so at the very least you have that going for you.
Fun Fact: I watched it with a Korean girl i'm kinda/sorta hanging out with, and I don't know if it's because I was watching a Korean girl get fucked in a Korean movie, in Korea, with a Korean girl, but it led to some awesome mid-movie sex. If you have the opportunity you should watch it with a hot Asian chick.
