I don't have any for that particular episode, but I do have a couple wincesty, domestic bunker recs to send your way. :)

Different As It's Always Been (http://runedgirl.livejournal.com/66274.html) by runedgirl: "On a cold November day in 2015, the demons finally gave up on Earth and went back to hell. The angels left a day later. Sam woke up in the bunker the morning after everything changed feeling exactly the same. It took four years, three weddings, two guinea pigs, and Dean nearly dying for Sam to realize that nothing was the same after all. Especially his feelings for his brother."

All I Want Is To Have My Peace of Mind (http://archiveofourown.org/works/1055115) by eugara: "Season 9. Dean thinks Kevin might know about him and Sam. Well, he's not certain, but he's pretty sure. Really pretty sure. At least, he thinks he is."

(You) Make a Mess of Me (http://runedgirl.livejournal.com/72806.html) by runedgirl: "It's Christmas in the bunker. Dean likes bacon. And Sam's hands."

yay thanks!

Further domestic bunker!fic wincest recs:

In Silence Sealed by rivkat
Fiercelynormal tagged me with “piercing.” After a hunt, Dean can't hear, but he can still talk. Warning: may induce diabetic coma.

Well, This is Awkward by Blue_Jay
After hearing Charlie talk about the Winchester Gospels, Kevin decides to check them out because it's not like he really knows all that much about Sam and Dean, right? And he really, really knows he should stop reading for the sake of his sanity, but it turns out the lives of two idiots who started the Apocalypse are more interesting than he thought.
Charlie agrees.

This one's a more sombre take on the bunker domesticity, because it's set sometime after 9x11, but it still has some very sweet domestic moments:

The Old Man of Peru by de_nugis
Sam gets bitten by a bat. He probably doesn't get rabies. He probably isn't a werebat, either.

Plus there's this fill at spn_masquerade:

The Way to Sam's Heart...
Dean decides to woo Sam with his awesome cooking skills now that there is a fancy bunker for them to live in. Sam is oblivious to his efforts.

yay this is great thanks!

I don't have any suggestions for that episode, but here are a few wincesty bunker fics:

Under Hill (http://archiveofourown.org/works/894164) by cordelia_gray
Summary: In which the Winchester's lives are only a little bit like a Disney cartoon, and it takes Dean a long time to figure things out.

Clear and simple and plain (http://archiveofourown.org/works/1018788?view_adult=true) by trojie
Summary: After Sam gives up the Trials, things start getting better.

Rough Riders (http://archiveofourown.org/works/813780?view_adult=true) by rivkat
Summary: From two spnkinkmeme prompts seeking a Sam who likes rough sex and a Dean who doesn’t like it nearly as much, but won’t admit that until Sam figures it out.

oh wow thank you!
