First time posting after lurking for months.
I'm never looking for specific fics because I make pdfs of everything I come across that I want to save for later. But I would absolutely love suggestions for similar stories.
I love reading stories were Dean is at Sam's mercy. Either because Sam is possessed or its Robo!Sam or he's just royally pissed off and Dean sort of suffers because of it. Some similar stories I've read are
Desperation Takes Hold by
someblazingstarand Confusion (i forgot the author or whether it was on ff.net or here) where Sam was possesed by a ghost but Dean didn't know and Sam was beating the shit out of him until Bobby came to the rescue. (I love it when Bobby comes to the rescue.)
Anything were Dean is reluctant to fight back because its Sam or even better if he truly can't because Sam is bigger and reasonably stronger because of his size.
Kudos if Sam is remorseful afterwards and/or Dean has a lingering fear or uncertainty that he tries to cover up.
Its preferably if its not slash and no RPF. If It is slash, nothing explicit. As far as "Desperation Takes Hold" goes is fine.
P.S.
I'll be indebted if you could fine one where Dean ends up getting concussed. There should be a concussion tag here like at hoodie time.
