I came across Fumbling in the Dark and read it surprised to find it changed my mind on the Sam/Dean pairing I had vehemently opposed before.

So, I'm tentatively reaching out to ask if anyone has any good Sam/Dean fics that are more of a slow romance- or that are not just smut, as I'm willing to give it a try. 

Anything you think might be a good introduction to this pairing. My OTP is already claimed but Fumbling in the Dark made me wonder if I was missing out on some good fics. Thank you.

As a side note- I was eased into the pairing by reading some Sam/Gabriel/Dean/Castiel- so if anyone knows any good polyamorous fics including those characters (three/four) I'm open to recommendations.
