Paris Dreams would have been a rec from me as well, but casey679 beat me to it! It's really good! Alpha in a Bottle, Honorbound, and Entwined Branches are all great, too.

Here are my recs:

A Steady Rain (http://archiveofourown.org/works/330626/chapters/533565)
Summary: When omegas go into heat, they have to be knotted or it is fatal. All omegas go into heat at puberty, but then very rarely after that. They always have to have a knot in them during their heat or it is very painful. Jensen's heat starts when he is far away from the pack. He's scared he's gonna die, and just when he feels the pain's getting too much, Jared, an alpha, finds him. Jared takes pity on him and decides to knot him.

Not Skin Deep, You're in My Soul (http://archiveofourown.org/works/940938/chapters/1834591)
Summary: Mated Omegas bond with their Alpha on a biological level, so completely that their body resists sexual advances from anyone else. Repeated knotting can make an Omega’s body accept a new Alpha, but the new mating bond overwrites the old one, erasing it not just from an Omega’s body, but from their mind as well. Jared wakes with a headache and a memory full of holes. He’s been kidnaped, drugged, and is about to be sold to the highest bidder.

ETA: Busy Being Born is definitely worth reading, as is The Cop and the Baker 'verse! You got some really good recs!
