Sam and Dean have to deal with long-hidden feeling for each other after Sam gets Dean out of his contract.

I have only one itching desire (let me stand next to your fire) (http://queerly-it-is.livejournal.com/843.html)
In which Sam teaches English and is exasperated, and Dean hates matches, gym class, and is kinda-sorta-maybe turned on by fire (undercover/casefic)

And here (http://www.diigo.com/user/kali0712/pretend!couple%20first-time) are the first-time pretend couple fics that I've bookmarked, they're all good.

If you don't mind a self-rec, I've got one that fits 8 and 11

Ain't Nothing Like the Real Thing, Baby http://tifaching.livejournal.com/8467.html

Rating: NC/17
Summary: When Sam was fifteen he made it pretty clear to Dean what he wanted. Dean made it pretty clear right back that Sam wasn't getting it if he didn't at least try to see if there was anyone else out there who'd make him happy. Sam tries. Sort of. Dean gets with the program. Eventually. Wincest ensues. Complete in three parts.

Solace in Your Massive Arms (http://lipsticknguns.livejournal.com/575.html)

Fluff, humor, hurt/comfort, protective!sam. Lots of cuddling.
