Hello all you wonderful people, i believe this one should be fairly easy (I hope)

This is GEN:

So I think i read this story about 3 years ago maybe 4- but basically it was actually a disciplinary/spanking verse kind. It was Set in season 3/4 Dean coming back from Hell, maybe it even started in Seasons 3? AS I recall a scene where Sam went summon the cross-road Demon that had Dean's deal and he shot here with the colt and when he tried to sneak back in, Dean caught him and well proceeded to put Sam over his knees and spank him.

Its Dean basically spanking Sam for misbehaving/lying/sneaking- in the whole verse and I think it is a verse because the same writer continues the story line with Season 4 when Dean cam back from hell and he finds out about Ruby.

I recall one of the Chapter Dean looks at Sam (after catching him lying again) and he informs Sam "you're gonna wish I haven't comeback from Hell"

So yeah if any of this sounds familiar to any one would appreciate the help :)

Also if you know of anymore Where Dean takes a firm approached with Sam after picking him up from Stanford or later seasons?

Love yous guys, thank you
