I just finished reading a story on Teaspoon that was incredibly well done. It had a great balance of angst, determination, and dawning romance. It's Nine/Rose in denial with Jack along for the ride and wanting to romance Rose a bit himself as the hapless pairing come to the realization that they are in love with each other. A bit of action into the mix and a fun plot. It was really just a delight to read. I did want to kick the Doctor in the head a few times from his misguided idiocy, but you know, in a good way. *laughs* No smut, it's not that kind of fic, but it's still worth the read you smut bunnymongerers, you. Especially if you love the Nine/Rose dynamic.
It's called Challenges, it's by Ree923, it's complete and you can find it here:
