I'm new to this site, a friend told me about this story she read about Sam having been born with a tail (it's not the Teen Antichrist verse which is very awesome) and John is really mean in the story. She couldn't remember who the author is but maybe you all could help with this fic search.
Sam may have also had dog ears.

I am also looking for any fics where John is really mean to Sam about anything powers, school, sexuality ..., But Dean protects him if he knows about it or rescues him.
No deathfics, No under 15 for Sam if its wincest and preferably no John/Sam.
Anything else is good with me.
