Younger Castiel (don't care about the age) being introduced to bestiality by Dean and totally loving it, being a total slut for it. Dean can also fuck Cas afterwards.
Would love for it to be very filthy with a lot of dirty talk and humiliation and Cas loving it and getting off to it. Dean calling him a real dog bitch, all that stuff.

Jared goes on a class trip to a human dairy farm. The trip turns extra educational for his classmates when the farmer claims Jared as a wild cow, and they get to watch him be processed and milked for the first time.

Among modern society, arranged matings for omegas, especially to older blood relatives, as well as the castration of omega boys after presentation are outdated practices that have fallen out of favor and have even been banned in some states. Arranged matings were meant to strengthen blood ties within the family, and the castration of omega boys was believed to increase their fertility, something that's not needed in an over-populated world. However, these traditions remain strong among hunter clans, who need strong bloodlines and bountiful omegas to ensure the clan's survival, since their work comes with risks and losses.

Recently orphaned, Dean and Sam are sent to live with Samuel, since he's their closest living blood relative. Dean is a newly-presented omega and Sam is still unpresented. Having lost his omega wife a few years earlier, and having now lost his only child, Samuel feels its best, as the head of the Campbell clan, for him to strengthen the blood bonds of his direct bloodline by taking his young omega grandson as a mate. Having grown up outside the clan, Dean is in for a real culture shock to find that not only is arranged mating still practiced by his mother's family, but also that all omega boys in the clan are castrated, and Samuel intends to have him cut, too, before claiming him and getting him pregnant.

Dean should be between 11-13 years old. I prefer full castrations (penis and balls both removed) over just the balls being removed, but whatever writer-anon wants is fine by me. Other kinks are welcome, feel free to add whatever. Please don't reprompt with changes.

Any situation/scenario that involves underage Dean being castrated.

I like the image of Prompto wearing nothing but a collar at Ardyn's feet while he pets Prompto's hair and feeds him by hand.

+Could lead to sexy times
+++++++Consensual

A wizard decides Cas would make an amazing familiar and grabs the angel.

When the brothers see the collar around Cas’s neck, they go crazy.

(All familiars, as they are usually were!animals or shifters, wear collars, and Cas’s wizard will not break with tradition; technically Cas falls in the same category as the typical familiar as he has two forms - his earth vessel and his true form in the ether).

Someone (Ardyn?) putting Ignis in a shock collar, For Reasons. Smut optional but extremely welcome.

I don't even know where I'm going with this, but, yeah. 18+ if there's anything sexual, and I'm absolutely game for Noct/Ignis on the side.

Set in an AU with a lot of social restrictions on submissives. Everyone expects Amicitias to be Doms, but Iris presents as a sub. Gladio asks Dom!Noct to collar her so he and his dad will still be able to see her sometimes and know she's being taken care of. Noct already has at least one submissive but he agrees.

Omegaverse is ok too as long as nobody gets pregnant. Please age Iris up for sex scenes.

+Iris trying to be the perfect sub by modeling herself off Ignis
+Gladio having to rein in protective instincts and taking it out on Noct
++Having to publicly consummate as soon as she comes of age
+++Public use/lending her out to other nobles

Inspired by the movie My father the hero.
Desperate to appear as a man and not a boy, Sam (anywhere between 14 and 17 years old) lies to a potential love interest and says John is his sugar daddy. The lie escalates and he ends up having to confess it to his father. I want to see how others interpret John's behavior according to the lie.
Super bonus if Dean is violently protective for some reason and Sam ends up lying about him too, saying he is an ex boyfriend.
Can be total AU or not, with actual sex or not, I'd be happy either way.

A spell has a slow effect on Dean. It magnifies his fear of Cas leaving, getting hurt or dying. He collars Cas to keep him under control and even puts him in a cage.

Can Sam save Cas?

I just need Noct,,,,,, collaring Iggy,,,,,,, please

Taking a deep breath, he grabs the collar and leaves the closet, flicking the light off as he goes. His bare feet are sticking to the hardwood floors, the collar is jingling, the silky pants are brushing against his legs, and he feels so at peace he might be a quarter of the way to subspace.

Steve looks up at him when he walks into the living room, glasses still on his nose, mission report in his lap, his feet are firm on the floor, knees spread wide enough for Bucky to fit in between.

He nods to the collar Bucky has gripped in his hands, “Want me to put on your collar?” Steve asks, his voice strong but gentle.

Bucky nods, stopping in front of Steve, between his open legs, “Please, Sir.”

Y'all. PLEASE. I just wanna read Noct wearing a hidden vibrator, and Any has an app on their phone that controls when it's turned on, what setting it vibrates at, etc.

Tripple bonus points if by agreement Noct is the sub to all the guys in an ot4 relationship, and they frequently use him or do Scenes that involve him wearing vibrators and/or cock cages (or even on one occasion, a collar) in public.

After a failed mutiny (can be one or all Chocobros) they forfeit their rights and instead of being thrown in jail Noct keeps them as pets/slaves.

++ they are kept naked on leashes
++ they have to get Noct off in public

Cas returns from a hunt to find the boys are under the effect of a spell. One that has convinced them angels are pets. Intelligent ones but pets nonetheless. They treat Cas as if he wandered into the bunker by accident. Dean distracts Cas long enough for Sam to use some kind of angel sedative on him. He wakes up in a cage. Collared with something that inhibits his Grace and which he can't remove. The Winchesters aren't unkind to him. They try to train him but he is to them a pet. He tries to persuade them but they don't seem to understand. When they decide to bathe him, he tries to escape and damages the Impala so they punish him. Up to you if this is a severe spanking or something else but it hurts badly and then Cas is shoved back into his cage and a cover put over it.

The brothers wake up next morning and the spell has finally worn off. The cage they find is a bit of a surprise. When they find a traumatised Cas inside they are horrified. When they realise it was them, they are stricken. But Cas needs them though it takes some doing to coax Cas out of the cage and settle him. And then to persuade him to stay. He's not angry with them, just hurt and skittish. More angry at himself than anything, for his reaction and for not being able to protect the boys.

That's it, that's the prompt.

Up to you what the situation is. Pairing, if any, is also up to you.

(Though I feel like should specify, I'm not looking for puppy play or pet play or anything to do with animals please)

Inspired by this fic https://archiveofourown.org/works/12094344 which was inspired by a prompt somewhere on this meme!

Gladio likes it when Noct is commanding. Noct likes his reactions, and over the course of a few months things escalate to Noct putting a collar on Gladio.

Prompto and Ignis are welcome, especially if they help Noct out with the idea.

Bonus points if the collar is welded on or otherwise non-removable.

Nyx and Libertus are both omegas, and they're used to helping each other through their heats. This time they're synced up, and alpha!Drautos finds them trying to take the edge off enough to get through the day. Rather than tell them off for unprofessional conduct (what they're expecting), he drags them off to his place to take them, break them, and make them into his loyal pets.

+Drautos has been planning this for a while. Toys, restraints, collars for once they've been good enough to earn it - he's fully prepared.
++Libertus and Nyx are encouraged to compete for the alpha's attention.
+++Drautos slips something into their food to make their heats longer and more intense, so he has more time to work on them.

Nyx is captured by Niflheim and given to General Glauca as a bed warmer.

Bonuses:
+ Drautos wants to keep his secret secure so he blindfolds Nyx/doesn't speak to him when they interact, and communicates via notes when he's gone
+ Nyx being led around on a collar and leash when they have to leave the room together
+ Nyx catches on that his captor is from Galahd and sex takes on an angsty, hate-sex-like turn until Drautos breaks down and gags him.
