omega!castiel   29

I've Always Known
Nobody's surprised when Dean Winchester and Castiel Novak end up together- they've known they were going to be together since they were toddlers. Sam's fairly certain he knows who he'll end up with too- but Lucifer Novak is much older and probably not interested in him anyway. Right?

Request:Dean/Cas, ABO, older!omega!Cas, age difference
Dean is the mature, ruggedly handsome alpha everyone swoons over. I don't want him to be written as young or naive, age 30+ at least, but seen as in the prime of his life, perfect age to settle down. Dean could be a business owner, surgeon, scientist, architect, anything but a mechanic (I'm so over that). Rich and successful, everyone thinks Dean's going to marry some perky young omega. (Can include horrible dates/matchmaking disasters/exasperated family if you like)

Cas is the aloof but sexy 10-15 years older omega Dean falls for. Equivalent of a career driven woman who marries later in life. Seen as the type who will never settle down, is not interested in kids etc. Truth is, Cas was never willing to settle.

Just give me Dean head over heels for bit of an ice queen!Cas, who is actually all kinds of sexy and sensual for the right alpha. Bitchy comments from jealous coworkers/neighbours would be awesome, along the veins of 'why did he settle for that dried up bitch? He'll never get kids from him' and then Dean knocks up Cas with twins on their honeymoon, or whatever.

And Cas very much enjoys younger!Dean's stamina and prowess in the bedroom. Top Dean only, and please don't repost with alterations.

Request: Dean/Cas, asexual Cas, abo, heat sex
Castiel (14-16) is an omega and he's asexual but during his heat that doesn't seem to matter and it's very upsetting to him. He's gone through a few heats alone and it's horrible, he hate that he can't ignore the lust and need to be filled. His next heat is coming up and he shyly asks his best friend Dean to help him through it. Dean's happy to help but he's also afraid it will change things between them.

Lots of heat sex and Dean taking excellent care of Cas including Cas's breakdown when he enjoys sex too much with Dean. Love confessions and Dean ensuring Cas that he's okay with never having sex outside of Cas's heats as long as he has Cas.

Repost: Castiel/Dean, omega/omega, past castration, size kink, first time

Castiel and Dean are in an omega/omega relationship, something that is only just becoming more visible. Being from a liberal family, Castiel is still intact, while Dean, being from a very traditional family, was castrated before puberty (balls removed, penis trimmed down to a nub). Since Dean is castrated and Cas is intact, there are some very obvious physiological differences between them, with Castiel's body retaining a masculine physique and body hair growth, while Dean lacks body hair and has the feminine physique common with castrated omegas. Cas also, notably, has a dick that seems really big to Dean (it's really no more than like 3 inches and definitely small compared to alphas and betas, but to an omega like Dean, whose own dick was shortened at a young age, that would seem huge).

Cas is a few years older than Dean and has had several omega lovers, some intact and some not, so he's not unfamiliar with a castrated omega body. For Dean, on the other hand, this is his first omega/omega relationship and while he knows Cas is intact, seeing proof of it for the first time is kind of mind-blowing (given his upbringing, he was probably only ever allowed around castrated omegas from families as traditional as his own). I'd love to see Dean and Cas having enthusiastic, dirty, possibly awkward first-time sex, exploring each others' bodies and figuring out what the other likes, with Dean extra enthusiastic about playing around with Castiel's big omega cock, while Cas teaches Dean everything he's learned from past experience about how to make Dean's tiny nub feel good, too.

Would prefer if omegas DON'T have boypussies. Bottom!Dean only. 18-19-year-old Dean, 22-23-year-old Cas. Please don't reprompt with character changes. Go ahead and add other kinks, I'm open to most things.

Request: Sam/Castiel - Alpha!Sam, Omega!Castiel, public
It's a really hot summer day and Cas is in heat. He really doesn't bother to move - it's too hot for that. Instead he is laying on the beach and let's himself get fucked by whoever walks by.

Request: Dean/Cas, abo, Cas/others, slave!Cas
An ABO fic where Crowley owns a slave house or just a lot of slaves. He is entertaining guests and the center dish on a gigantic table for the first course are two omegas in heat. They are trussed up like stuffed pigs but their holes are open and leaking into a small bowl. People can just put their cup against the omega's ass to collect some slick to drink, finger the omegas, touch them however they like. The omegas haven't been able to get any relief during their heat so that they are ready for the party so they are pretty delirious but no one notices or cares.

Except this time one of the omegas is Castiel and Dean Winchester is an alpha at the dinner party. Half way though the first course Dean can't take the hands all over the beautiful omega anymore or the tears leaking down his face. Dean buys him flat out from Crowley but Crowley makes him wait until the end of the first course to take his new omega from the table.

Once the first course is over Dean pulls the omega into his lap, he takes out the gag and holds the shaking omega. He promises to take care of him and keep him safe. Then fingers an orgasm out of him while feeding himself and the omega dinner.

Request: Dean/Cas, abo, forced intimacy? Slavery
Dean is an alpha, he thought he'd be sold as a labour slave or guard. Never in his life did he think a male omega would buy him as a pleasure slave. He's not built to grovel and mewl for someone.

But Castiel doesn't want that, he wants to be fucked, hard and feral. So Dean does but he doesn't understand why his owner throws him out the moment it's over. He's never allowed to care for the omega that is clearly starving for affection and doesn't even realise it. Dean shouldn't risk his life to try and take care of his owner in a way that's forbidden but it makes him sick to leave the man bent in half, cum dribbling from his hole and still panting.

So the next time he knots Castiel, and spends 30 minutes tied to the man, soothing his anger, massaging all the tension from his body and coaxing him to sleep. He isn't thanked for it, he's put in a cock cage and Castiel doesn't touch him for weeks, using other slaves as if to spite Dean. Until Castiel goes into heat, he can't get off with anyone and knows that he needs his green eyed alpha. He summons Dean and rides him, snarling that he is the one in charge and that Dean will respect him. Again Dean doesn't allow Cas to get away from his knot. He accepts the initial punches before pulling the omega into his hold and forcing him to scent Dean.

Dean spends the whole heat taking care of Castiel. He won't allow any one else inside. Castiel is furious that Dean is so presumptuous. Cas does like it he's just afraid, always afraid that an alpha will assume control over him.

Request : Destiel, Alpha!Dean/Omega!Cas, secretly caring Cas'family
As for the story, I'd like an ABO world where omegas are treated like second class citizens (so, the usual) and Cas'family, all alphas and betas, have a reputation for being very conservative and treating the youngest and only omega of the family, Cas, like crap (also the usual). Except, it's all a front. Behind closed doors, they're doing everything they can to help out omegas and are fiercely protective and loving of Cas. But nobody can know because Cas could be taken away (or something to that effect).

Then Alpha!Dean comes along, falls in love, and decides to save Cas from his evil family. Said family who's not too keen of Dean either, thinking he's just another douchebag alpha (at least at first).

Please, even if you write an angsty fic, let there be an happy ending, with Dean and Cas together and Dean getting along with Cas'family. While not an imperative, it'll be nice if the members of Cas'family included dickish angel whom, in this case, would only seem dickish : Uriel, Zachariah, Raphael, Naomi, Metatron, etc. Zachariah and Naomi as Cas'parents sound good.

Request: Cas/Dean, abo, culture clash, wooing
Castiel is a city born and very cultured omega. He's educated and independent. Dean is a feral alpha possibly a leader of a pack. He's street smart, charming and wise. Dean somehow ends up as Castiel's house guest and it is going to be Castiel's doom or that is how he begins to see it.

Dean is very grateful but he also knows that he's found his mate. Culture clashing stands in his way. I'd really love for Dean to try and woo Castiel but it's kind of like he is peacocking. He tries to prove that he can provide for Cas and when the feral way is rejected he looks for ways a city omega would find pleasing. He is constantly praising Castiel and like a happy puppy when Castiel accepts presents and such.

But also Dean has to prove that he is virile enough for the omega, he walks around naked whenever possible and as soon as he feels that the advance is welcome enough he spreads himself out in front of the omega and presents his cock. Stroking it to full hardness and maybe offering his precum to the omega to taste. Jacking off and showing off his knot and how much sperm he produces by cumming all over himself.

Castiel is very conflicted because everything Dean does pleases Castiel even when he thinks it is too primal to be proper and beneath him. Of course over time he understands that the feral weres aren't as beneath them as the city weres say they are. Most city were don't even like to believe they are of the same genetics as the ferals, especially Castiel's family. And when Dean puts on that display Castiel is shaking with the desire to present himself to the worthy mate. But he won't he can't he really really shouldn't.

Request: Dean/Cas, Cas/dogs, a/b/o, beastiality, non/d
Cas (10-12) is Dean's next door neighbor. Dean positively adores the little omega and is already in talks with his parents to present a bethrothal gift when he turns 14, the legal age for mating. Maybe he's already doing some courting, little gifts, chaste pecks, things like that. Cas' parents are happy with the match; Dean does well for himself, and also fosters dogs, which Cas loves and he always wants to help Dean take care of them, often taking them out and feeding them when Dean's at work.

Dean's taken in three large foster dogs who were used in illegal porn, they've been trained to mount and breed omegas. Obviously, Dean keeps them locked up whenever Cas is over and won't let the omega take care of them. He's also told Cas' parents about the dogs and warned them not to let Cas over when he's not there. Cas thinks it's totally unfair that he doesn't get to play with these dogs, so he sneaks over one day while Dean is out, which is how Dean comes home to find him pressed beneath one of the dogs, little body dwarfed by the huge dogs. There are tear stains on his cheeks and his skirt and panties has been viciously torn away. It's pretty clear that the dogs have been taking turns with him. Dean of course rescues him, cleans him up and comforts him and returns him home, where he assures his parents that as long as Cas still wants him, Dean still wants to mate him when the time comes.

Cas can either hate it the whole way through or grow to love it (and being very ashamed of that). Intersex omegas please!

Optional: Dean being reluctantly turned on by Cas' gaping, cum soaked cunt and fucking Cas before cleaning him up, but only if Cas consents. Also possibility for Cas to get pregnant with puppies, which is a shame on the family, but Dean still loves and adores him.

Request: Dean/Cas, shapeshifter!Cas, omega!Cas
Dean 14-16 is walking home and finds a stray dog curled up and whining. He feeds it some scraps and tells him to cheer up. The dog has gorgeous blue eyes and when he decides to continue on his way the dog follows. Dean begs his parents to let him keep him, Sam is over the moon when they agree.

The dog is really attached to Dean and follows him everywhere. A few days in Dean discovers that his new dog can change into a person, a boy a little younger than himself. Castiel is kinda clingy but also very shy, he was thrown out from his family because he presented as an omega and his family considers male omegas worthless. Cas is afraid that he'll lose his new family. Dean wants to tell his parents but Cas begs him not to, he doesn't trust adults. But he eventually agreed to letting Sam know.

Things are good for awhile until Cas goes into heat. His first one he'd been locked in his room and only the bare minimal was explained to him. Dean has no idea what's happening, he's never heard of anything like this. Lots of cuddling at first just because Cas says it makes him feel better. Eventually Cas presents to Dean blabbing about how empty he is.

Virgin, though not innocent Dean and Virgin Cas. Lots of heat sex in both human and animal form (which Dean isn't keen about at first)

Request: Sam/Cas, Dean/Cas, Dean/Cas/Sam, soapy ABO
Dean and Cas have been best friends ever since Cas'family moved in next door to Dean's, when Dean was 4 years old and Cas 5. They became and stayed tick as thieves. And everyone could see, as they grew up, that they were in love with each other. Even Sam, who always had a massive crush on Cas but whom Cas only ever saw as a little brother. When Dean turned out to be an alpha and Cas an omega, Sam pretty much abandonned all hopes to ever be with Cas.

But Dean and Cas were fools, too afraid to admit their true feelings. Cas left for a fancy University far away (in another country) from Lawrence. Dean and him stayed in touch via Skype, etc.Sam and him also stayed in contat, but they only communicated by letters. Maybe because Sam, whom realised he was not just crushing on Cas but was in love with him, hoped that not seeing his face would help him fall out of love. Their friendship became stronger. Alpha!Sam tried to make diverse romantic relationships (with Jess, Sarah, etc.) work but none of them sticked.

A few years later, Cas came back to Laurence. Finally seeing each other face to face, him and Dean couldn't deny any longer that they wanted to be together. They became a couple and it was perfect. Well, almost perfect, because Cas, upon seeing Sam all grown up, finally stopped seeing him as a little brother and started to develop strong romantic feelings about him.

While rare, poly relationships were still accepted. But a relationship which involved two family members was more frown upon. How Dean discovered that Sam and Cas were in love and how he reacted at first is up to the person whom will fill this prompt.

Request: (O)Cas/(A)Dean, truemate, heat, denial
Castiel is in his late twenties, he's a teacher at a mid-sized high school and looking at a future as a guidance counsellor as well. Things take a sharp turn in his life when a sixteen year old alpha with trouble stamped across his forehead moves into town. Castiel starts catching lingering scents of the best thing he's ever smelled in his school's hallways. He's determined to ignore it because nothing good can come from an office romance.

When the scent that has been teasing him for a week fills the room of the detention hall and red is bleeding into emerald eyes that are trained on him, Castiel is fucked and not in a good way. All through out the hour detention Dean is a cocky son of a bitch, trying to get under Castiel's skin and look good in front of the other delinquents.

Castiel's heat is triggered and he spends half a week desperately trying to deal with it and not think about the young alpha. Who on Thursday in the middle of the school day is knocking on Castiel's front door.

Dean is not the little punk he portrays himself as, it's still a canon verse and he isn't going to fuck up some poor omegas life just because he's perfect. But, when John calls to say that they'll be leaving town Saturday Dean can't follow through with the plan and knowing the man hates him. He hunts down Castiel which isn't hard for a kid with hunting skills.

Heat sex and mating and Cas kinda freaking out that he's tied himself to an underage alpha but Dean promises it'll be alright. He steps up to the plate, refuses to leave with John and refuses to let John take Sammy.

Request: Sam/Dean/Castiel, Dean/Castiel - ABO
Dean and Castiel are happy together, no matter how frowned upon it is that they're both Omega's. They don't want children and can usually work around the heats with knotting dildo's. Too bad that they cycles overlap this year and they realise that they going to need an open-minded Alpha to help them out.

Which brings them to Sam, who has sworn off relationships a long time ago after pack died - including his wife and his cub.

Up to the author if it's really just sex with Sam knotting Dean and Cas or if it leads to love or at least an open relationship.

Request, Cas/other, Cas/Dean, abo, true mates, angst, possessive behavior, guilt
Dean meets up with some other hunters and finds that one of them has the perfect omega Dean's ever set his eyes on. After the first meeting, he's had to douse himself in scent blockers and does his best to be around the pair as little as possible.

The alpha hunter knows immediately that Dean wants his omega, they aren't perfect mates but Castiel is his. He proves it every chance he gets he has Castiel fuck himself on the alpha's cock or suck his cock. He even plays with Cas until the little omega is wrapped around him dripping and begging to be mounted.

When Castiel met the hunter Dean he'd never smelt anything better. He'd been riddled with guilt because of how drawn he was to the stranger. But, after that his alpha was very attentive and the scent was absent.

Torture Dean with having to watch all of these PDAs but end it with Cas and Dean. Maybe the other alpha dies in the hunt, and maybe Dean didn't have the guys back as well as he should've. Or he could steal Cas away after ridding himself of scent blockers and finding Cas alone. Any way you do it Cas feels guilt that he wants Dean more than he ever wanted his alpha.

In the ABO world Omega have special pants. They have an extra zipper so that they can be fucked anywhere at all because Omega's exist as Alpha stress relief. Wearing the pants means you consent to being bent over on your way to work and getting fucked by someone who have never seen before.

Good thing that Omegas are always wet. Or at least get there very quickly.

Gravity vs Velocity
Newton's law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between the two bodies. Police officer Dean Winchester swears he feels an honest-to-goodness gravity (not any scent-true-mates-bullshit) pulling him to a mysterious omega in the holding cells and makes the worst mistake of his career. He only has one thing to say... Fuck science.
