Sam is getting tortured by Toni and thinks Dean is dead. Somehow a hellhound attacks the base and Sam kills it, getting the hellhounds blood all him. He then remembers the Trials of Hell and says the chant to activate it. I remember the British men of letters freaking out about it but eventually ends up letting Sam do the trials. So for the second trial Sam goes through purgatory again and meets up with Benny, who followed Sam because he smelled him. They go to the entrance to hell and the British men of letters gave Sam a compass type thing that points out innocent souls in hell. He finds a girl who sold her soul for her sick sister I think and brings her back. He gets attacked on the way back but Benny comes to the rescue! So they go and Sam does the spell thing to Benny’s soul into his arm and revives him but Sam doesn’t have much time because the British men of letters is expecting him at a metting point. At some point Sam prays to Cas and explains how he started the trials again and Cas tells Dean. I’m pretty sure the Sam and Dean had been having connected dreams but didn’t know. They just thought it was a dream and Dean starts ranting at Sam about how he started the trial again and how could he do that and they realize that the dreams are real. At some point Toni is making Sam have a dream about how they’re on a date or about to sex and Dean shows up and makes Sam realize he’s being tricked. Dean ends up saving Sam but they continue with the trials because of some reason and use Crowley as the demon to cure. As Sam is curing Crowley demons come and like beat up Crowley I think and it makes it so that if Sam cures him, Crowley would die but Sam still does it. After Sam completes the trials he pukes up this tiny thing and realizes it’s the demon blood and then dies in Deans arms. Billie comes reap him but Sam has this torch thing that Amara gave to him that was from chuck that basically brought him to life. Could’ve been Wincest, idk. There is also another character called Mary who talks with Sam during his captivity and is meant to be kind of like a motherly figure.

I'm looking for stories where Sam and Dean have sex because of the Mark of Cain. In particular I'm looking for stories where Sam is doing it to keep Dean close, away from Crowley and/or helping Dean control the impulses of the mark. But any stories that fit this criteria are fine, i.e. if Dean does it as a form of punishment or revenge against Sam, etc.

I also wonder if there are any stories out there where Amara offers Sam to Dean if Dean will stop trying to stop her.

Thanks.
