The Men of Letters are big on legacy. They are quite determined that the Winchesters play their part. They order Ketch to arrange for them to procreate.

Getting Sam's current girlfriend pregnant is almost too easy, but Dean hasn't so much as had a hookup in months.

Ketch gets impatient and takes matters into his own hands. Using a curse or spell or potion, up to the author, he makes it so Dean can get pregnant. Then makes sure he is thoroughly bred. Up to the author if Ketch does the deed or if he has someone else do it.

[BabyBat (BabyBatsCreations)] Sam thinks he's safe. He thinks the days of Gabriel sending horny animals after him are over. Until, he gets a knock on his door and finds that Gabriel isn't gone, he's just changing the rules. That angel doesn't know when to quit, but maybe Sam isn't as hesitant this time around. [Sam gets fucked by animals turned mostly human, including a dog, a bull, a bunny, two cats, and then an actual wolf.] (Animal Instincts 2)

[BabyBat (BabyBatsCreations)] This is not what they were built for. This is not what they are. But it is what they do now. And it is what they have become. Sam has a bad feeling about his new job at Freddy Fazbear's Pizza. The pay is terrible, the hours are worse, and everything about that manager is weird. But someone has to pay the bills and Jess can't do it alone right? Keeping the lights on is suddenly the most important thing in Sam's life as a matter of fact.

Sam woke up in slow, aching degrees. First, he registered that he was on his back, rubbing against something rough. Second, he figured from the cold that he was completely naked. Then, from the pain and hard hands holding his legs open, he realized that he was being fucked. Hard.

Dean's decided to share his girl with Sam

Sam finds a video of Dean fucking a girl. He knows he should have stopped watching when he figures what it is but he doesn't. He keeps watching and comes to the sound of Deans voice whispering dirty, pretty things to the camera. It becomes his go-to jerk off material and it's starting to affect his relationship with Dean. Dean finds out somehow...

Consent up to author, additional kinks welcome.

[omgbubblesomg] There's always someone looking, no matter where hunting takes them. Lonely housewives, horny businessmen. Anyone with enough money and inclination. (Read the comment section for more!!!)

Say John raised Dean and Sam to have no shame in doing what they needed to to get by as hunters, from poker to pool to credit card fraud to a little sex in the backrooms for money. (Although he was strict about them not doing that last one until they turned 16.)

I just want to see adult Sam and Dean, still hooking occasionally to get by, and perfectly fine and well-adjusted about it, with no angsty moral qualms or hangups, no shame, no desperation. Making sure the other has condoms and lube on him, or checking in by phone for safety, or talking about the great sex they had with the last client (male or female) while they are fucking. Maybe outsider POV, someone like Cas who doesn't understand why it doesn't bother them

Sam gets addicted to being roughly fucked by strangers, and it's even better when he gets paid for it(he feels even more dirty)- while Dean's in hell; what happens when Dean finds out once he's back? H/C plz.

Everyone always thinks Sam has a big dick because of his height and how obviously everything has to be big about him.
However that's actually not the case, his dick is barely average, which, on his big frame, looks really small.

Basically I want a story about every partner and hook up Sam's ever had and how they always tell him what a big dick he must have and when they see Sam naked they get very disappointed and Sam is humiliated every time and gets angry and moody the next day. That's how Dean finds out about his little problem one day (please NO Wincest!! Just some brotherly ribbing)

Bonus points for side!Destiel

Dean (16-17) has a date with a girl from school but it's not long before she asks to hang out at his place. Dean, hesitant since he knew Sammy (12-13) was there, eventually brings her back to the motel room they were staying in. At first, Dean assumed they were only going to watch movies on the crappy TV in their room but Sam's already using it, sitting on the couch. Dean and the girl end up talking some on his bed before the girl starts touching him and kissing him. After some making out, the girl wants more and climbs on his lap. Dean sees Sam had turned around and was now watching them. Dean tries to stop her but the girl persuades him to let her keep going, to let sam watch. Dean, too turned on to say no, goes along with it.

It starts getting heated and the girl is taking off their clothes and Sammy is still watching. Dean glances at him a few times and feels weird that he was getting more turned on by the fact his little brother was watching this all. Dean ends up fucking the girl, coming a little too fast for the girl's taste so she looks at Sam and asks if he wants to join. Dean's about to say no but Sam eagerly nods and hurries over to the bed. Dean would be lying if he said he didn't want to see this so he lets the girl coax sam to take off his clothes and get between her legs, let's her guide Sam into her and helps him with a steady pace while telling him to kiss at her breasts.

Dean ends up coming for the second time by watching the show in front of him.

[waywardelle] At age 32, Sam Winchester presents as an Omega. No one is more surprised than Dean, the Alpha who's been pining over his little brother all his life. Canon divergence after scene with Piper in 11x04, "Baby." (Brother-Mates 1)

[BewaretheIdes15] Sam may be his alpha, but Dean's going to show him exactly who's in charge. (Werewolf Porn 2)

Sam's a jealous little brother, and he's gotta have Dean all for himself. So when Dean starts dating someone Sam doesn't find worthy of him, Sam seduces Dean's sweetheart and exposes them as a cheater. Even if they try to come clean to Dean, Dean's never going to believe them that Sam was the one they cheated on him with. 'Cause, y'know, Sam would never. All that's going to do is to prove that Dean's SO was trouble to begin with.

And then Sam gets Dean's undivided attention. Again.

Dean's partner can be anyone from the show or an OC, male or female. They can actually be a dick or it can all be in Sam's head (just no woobie!Dean, please). Sam can be full-on in love, requited or not, or just simply a jealous little brother. Eventual Wincest's a bonus, but I can live without if you'd rather go the platonic route.

[PosingAsMe] His friends and colleagues might refer to him with fondness as a moose now, but there was a time not so long ago that Sam was known as The Stag. Now that he's a respected prosecutor, he'd rather his former glory as the star of certain blue movies stayed in the past where it belongs. As his best friend Cas learns quickly, films were just the beginning of this secret life. He begins to think he knows nothing at all about the man who has been his friend for years. But he can't help wanting to know more.

After the demon is exorcised and the dust settles, the Barnes twins take Sam back to their hotel room to show him exactly how grateful they are for his help, not to mention saving the world from Lucifer. They guess (rightfully so) that what Sam needs is a break from all the pressure and responsibility... preferably one that involves bondage, kinky sex, praise and being their sub.

The Impala is an asexual being and would really appreciate it if the Winchesters would stop having sex on her back seat. Also, if the could tidy up a bit more often after eating, that would be great.

Anthropomorphic Impala, unintentional voyeurism, unintentional exhibitionism, dub con

I was always confused by the portrayal of Soulless!Sam as an incredible fuck. Like so good the prostitute forgot to ask for money. That made no sense to me. Being soulless he should have been a selfish asshole when it came to sex.

I want to see Soulless!Sam not giving a crap about anyone's pleasure by his own. His bed partner can call him on it.

So let's say the amazons decided that Dean and Sam made excellent stud stock. It'd be far easier to keep them for breeding purposes than constantly be seducing and bedding men in every town.

So they capture the Winchesters and set up a home base somewhere. Sam and Dean fight constantly, never giving in. They take beatings, starvation, humiliation, but they still fight.

It doesn't stop them being taken against their will and made to father countless children as the amazons reproductive cycle is unbelievably rapid.

They keep planning their escape. Even though it means maybe killing their children, as their grown up daughters are the ones guarding them.

I'd like it if they do get away and their imprisonment isn't prolonged, but please no incest.

What it says on the tin ;) some het anal sex would be awesome. Sam or Dean and any female character, but feel free to make it a threesum as long as the girl is the one getting fucked. Slightly rough con or dubcon, noncon is fine if she eventually enjoys it.
Surprise!anal where he slides in without warning or accidentally would be even more awesome but it’s entirely up to you!!!
