Deancopious

Author: Masoena Artist: TwinOne Pairings: Dean Winchester/Sam Winchester, Jensen Ackles (French Mistake)/Dean Winchester, HunterCorp Dean Winchester/Sam Winchester, Dean Winchester/Endverse, Dean Winchester/Sam Winchester Rating: Explicit Word Count: 20k Warnings/Tags: Explicit smut, porn with plot, bunker era, mildly dubious consent, wincest, sixsome

Summary: Dean being cagey is never a good sign and Sam quickly figures out just what his brother has been brewing up as a surprise for him or the fic where 4 Deans and Jensen (from French Mistake) show up at the bunker sometime vaguely set in season 15. In context of established wincest we learn about those visitors plot wise and get to be a fly on the wall to see all the smutty shenanigans that would ensue if Endverse Dean, Demon Dean, HunterCorp Dean, Jensen and regular Sam and Dean got to spend a 24 hours together in the bunker.

Bad Day at Castle Storage

Author: FriendofCarlotta Artist: saudade Pairing: Castiel/Dean Winchester Rating: Explicit Word Count: 20,509 Warnings/Tags: Crack, Thief Dean Winchester, Hunter Castiel, Curses, Slapstick

Summary: Dean’s always lived by one simple rule: if a job smells fishy, don’t take it.

It’s a rule that’s kept him (mostly) out of prison and unstabbed. Sadly, it only takes you so far when the rent’s a couple months overdue and the loanshark you play a friendly game of poker with has run out of eighth and ninth chances to give you. So when a British chick calling herself “Ms. Lugosi” contacts him via one of his usual guys to say she just “needs something fetched from storage for a client,” he does it.

Or, the one where Dean steals a cursed rabbit's foot from Cas' storage unit, and hijinks ensue.

Let’s Go Home

Author: need_more_meta Artist: Amberdreams Pairing: Dean Winchester/Sam Winchester Rating: Explicit Word Count: 12,777 Warnings/Tags: 5+1 Things, Getting Together

Summary: Five places Dean has thought of as home and one that actually is.

Set right after 14x12 Prophet and Loss with memories from 1983, 1991, 2005, 2011, and 2013.

Sunkist and Sudafed

Author: Sparrow1M Artist: TwinOne Pairing: Gen Rating: Mature Word Count: 10,500 Warnings/Tags: Graphic Depictions of Violence

Summary: With Sam gone and Dad off on some hunt of his own, there's no one around to notice when Dean disappears. He finds himself aboard an alien spaceship, killing more monsters than he'd ever dreamed of on Earth—until the arena manager gives him an ultimatum.

Dashboard Confessional of a Teenage Dirtbag

Author: Ophelia_Yvette Artist: Solstheimart Pairing: Gen Rating: Teen and Up Word Count: 5,198 Warnings/Tags: Teen Pregnancy

Summary: If you’d have told Dean Winchester that he’d become a father at seventeen, he’d have called you crazy, but he also would have been wrong.

He’d never thought about having kids before this, not really. He always had Sam to look after since their dad was always away on hunts. Not to mention he was only seventeen years old and was still a kid himself, not that he’d felt like one in a long time. And he never would be again; of that he was certain.

His poor decision-making was how he found himself pacing the hallway of Garnet Health Medical Center in upstate New York, for exactly this reason; he was about to become a father at seventeen years old.

Lover Boy Rules

Author: SamandDean76 Artist: lena.arting Pairing: Castiel/Dean Winchester Rating: Mature Word Count: 5,776 Warnings/Tags: Fix-It Fic, Stanford Era Dean, Cas In Alternate Vessels, Older Rocker Dean, Happy Ending

Summary: All Dean wanted was some peace and quiet to eat his breakfast. But a goofy little guy named Gabriel invited himself into Dean's booth at the diner and conveyed a wild tale, where Dean was the only person in all of creation who could rescue a lost angel, who had taken refuge in an alternate vessel. Dean didn't understand most of the nonsense that Gabriel was spouting, but a few finger snaps later, and he was beginning to believe. When he finally ended up taking the stage, to give the performance of a lifetime, he realized that sometimes, all you truly need, is a little faith…
