I'm looking for a specific fic, which may be a figment of my imagination.

If I remember correctly, Jensen and Dean were twins. Dean was an omega but faked being alpha likes his brother. Jensen was a Doctor. Sam and Jared were running away from a very traditional pack and Sam goes into heat. Ends up being a Jensen/Sam and Jared/Dean fic.

There was the usual collection of CW actors making up the cast as well.

Does this sound familiar to anyone?
