It's just straight sex, but every scene is incredibly hot. No anal, not very nasty, just a sexy authentic woman having what appears to be truly enjoyable sex. irresistable even if you like it nasty.
I have seen only disc 1. She is a gorgeous girl but the sex is not very creative, which in my opinion is wasting such a hot woman.... I mean, she definitely inspires much more passionate scenes... If Rocco were the male star, the sex in these scenes would have been so much better. My favorite scene was when she played a high school girl.
Part 1 is six Evelyn Lin scenes. A must for Evelyn Lin fans (like myself), but will most likely bore other viewers as many NS scenes have very formulaic scenarios. While this works okay in a movie with six different actresses, seeing six scenes that are all similar by one actress gets a big repetitious. Still worth the rent if you like Evelyn, though.
