Thank you! And oh gosh, even tho angry!sex and hate!sex is very common in this pairing, there's still quite a bit of romantic smexing as well. If you haven't read her stuff yet, go check out fabularasa's fics here. There's some rough stuff, but it's usually more on the romantic (if angsty) side of Snack and OMFG so hot! Her stuff is totally what turned me on to this pairing. (And slash, for that matter.) It was written back before the fifth book so is out of canon (Snape's a pureblood, Sirius isn't), but the writing quality is such that you really just don't care. There are other Snack fics with more romance than hate!sex (tho there's nothing wrong with that, of course) but if you're looking for something a bit like this, that's a great place to start.
