So I'm looking for an audiofic I listened to a year or so ago. I remember that the song "A Horse With No Name" by America was in it.

So pretty much what happens is that Dean and Sam go into the past at some point and meet young!John. He finds out that they're sleeping together but doesn't care because he doesn't know they're related. He just started hunting so they teach him some things like fighting. He finds out that they're related towards the end. They're in the desert and at the end they see their young selves playing in the yard (I think). I remember that the monster they're hunting is a skeleton horse (or something like that).

If I were to guess, the fic is probably longer than 30-45 minutes.

FOUND: Thank you patty1h for all your help! (:
