The fanfiction I am trying to find is an m-preg with Destiel. I know that Dean is the one that's pregnant in it and the fanfiction has him nesting. I remember a very specific scene where Dean asks either Gabriel or Balthazar to give him their jacket. The nesting takes place in Bobby's house I think. The fic includes him having an egg that he has to incubate. I just cannot find it anywhere and I just had the need to read it again.
