[HC] Being Alpha!Koga’s Omega and Inuyasha’s Sibling

Masterlist

Originally posted: Mar 14, 2021 Slightly edited: Dec 22, 2022

mentions of injuries/getting injured

you were the youngest of your father’s children and a full-blooded demon

you are closer to inuyasha than to your oldest brother, mainly because you are closer in age 

koga met you when you were both still young

he was not the leader of the pack back then but merely another alpha in it

so, of course, when he met you, he did a lot of grandstanding

he would brag to you about all the prey he had hunted and the enemies he had slayed and he would also ask his friends to fight him so he could prove to you how strong he was

you pretend to be indifferent about it (being tsundere runs in the family ig)

but you’re obviously as entranced by him as as he is with you 

i mean how could you not?

still, you’re not gonna just make it easy on him

he almost gives up on it too

you went hunting together for the first time and as a sort of last-ditch effort, he goes to fight the largest animal he can find

this does not end well for him as he is impaled by the tusks of a boar the size of a horse

luckily for him, he was hunting with you

as the boar is distracted by the alpha, you manage to kill it

then drag his ass back home and nurse him up

he’s even more into you now

luckily for him, seeing him wounded like that, made you realise how foolish it was to hold out on him like that

so you confess to him

he’s so happy his tail is literally wagging like that of a dog’s lmao

the two of you worked yourself up through the ranks of your pack over the years

you were a nomad when you met him, intending to only stay with the eastern yokai-wolves for a short while but this had changed when you became his omega

many years after you joined the pack, koga comes to the cave you’re currently living in with a screaming human omega hanging over his shoulder

the strangest part about this for you is not that she can apparently sense jewel shards but that she smells heavily of your brother inuyasha

before you get to talk to her, there’s another confrontation with the birds of paradise

enter inuyasha

after saving his omega from the clutches of the evil wolf yokai, he finally realizes that you’re with them

cue yelling match between two immortal siblings who haven’t seen each other in like a century or so

cue your mate trying to defend you to your mutt of a brother

cue you brother tearing your wolf mate a new one

original note: i haven’t finished inuyasha so i’m leaving it like this for now until i’ve seen more of the show and of koga

editing note: still haven't finished inuyasha lol

└── ˏˋ°•*⁀➷ ••✎•• ──────────

≿━━━━༺❀ koga kitamikado ❀༻━━━━≾

✿ you were the only child of a famous art-dealer and an ushi-oni. living life as a half-ayakashi has been hard, especially as one so volatile. you're often found at the piers alone, with a scowl on your face. recently, strange things began to happen around you.

✿ you were 22, while koga was 24. it'd been 8 years since your mother died, and 8 years since koga's parents died. neither of you had quite been the same since, just in different ways.

✿ you'd been out, brooding at the piers, staring at the comings and goings of the ships. your father was... around, somewhere, waiting on an another shipment that was coming in. that was probably why koga was there, to buy whatever was coming in. and via whatever link that you shared, he noticed you and was drawn to talk to you. though you weren't particularly enthused about this fact.

✿ koga didn't really mean to keep showing up in your day-to-day life, but he was a client of your father's and a well-known figure around the capital. and every time your paths crossed he attempted to hold a conversation, which you eventually got tired of rebuking. it didn't take long after that for your onmyoji powers to manifest and his true nature to be revealed.

✿ koga thought you most interesting. something about him was drawn to you, not only due to how lonely you seemed. he didn't like seeing people be lonely in the first place, but you especially he never wanted to see unhappy. to his unfortune, you seemed to always be that. you, admittedly, found koga to be compelling. or at least your soul did. you on the other hand mostly found him increasingly annoying with his attempts to talk to you. that, added with the constant strangeness surrounding you... well, it made you a bit grumpy about him to say the least.

≿━━━━༺❀ kuya ❀༻━━━━≾

✿ you were the only child of a famous art-dealer and a futakuchi-onna. your mother had incited a deep seated love for food in you (despite your "small" appetite) which lead to you apprenticing at many restaurants around the capital.

✿ you were 22, as was kuya. you'd been apprenticing at various restaurants around the city for six years, two years prior to that your mother had died. kuya was freeloading at koga's, as expected.

✿ kuya and koga had reservations at a restaurant you were apprenticing at. you were assigned as their chef, which was a problem as you'd recently begun to feel hungry, which is when your ayakashi-form is the most prone to appearing. after several incidents of almost getting caught (and having to stuff your second mouth with a tablecloth), kuya spared you by insisting that they leave.

✿ you weren't actually certain if kuya had picked up on your... strangeness, but when he came by a second time (alone) and asked for you to serve him again you were fairly certain he had. he didn't pry into it though, and simply became a regular at the place and a couple of others you often worked at.

✿ kuya found you weird, mostly. but fascinating for the bits he was actually awake for. you were quiet, didn't try and disturb him, and besides your sometimes odd behaviour you were cute. and maybe he was inexplicably drawn to you, but who's to say to that. kuya was so so nice. you didn't know if he meant to be, but he was. his visits often allowed you to calm down your more base urges in privacy, as he spent most of his time sleeping while visiting, which made your life far more easier than it'd ever been. he truly entered your life at a perfect time.

≿━━━━༺❀ ginnojo ❀༻━━━━≾

✿ you were the only child of a famous art-dealer and a nure-onna. you were often found around the city helping around children and animals. you're pretty known around the capital for watching over all the children and protecting them.

✿ you were 26, around the same age as ginnojo would be if he was human. dragon's age so strangely. it'd been over two decades since your mother died.

✿ you'd been organizing a little reading nook in the park, where you would be reading for the younger kids and the older kids could find books that they liked. so, you were scouring every bookstore in the city until eventually you ended up at ginnojo's. it was a very strange visit, as ginnojo was far too nervous to actually talk to you the whole time, but you found the best books there so your search ended in success.

✿ after the first time, you started frequenting his shop as it had the best collection of books you'd come across. that, and they all seemed oddly impervious to all the rain that happened when you happened upon a bad mood. ginnojo however did not get any better at actually talking to you.

✿ ginnojo found you attractive. it was as simple as that. you were an attractive alpha, and he had no idea how to interact with any part of that. not to mention, something about you seemed familiar. he couldn't place it, but he was sure that it was important. that you were important. ginnojo was very cute. he barely said a word to you, but you could tell that at least. and he felt like a kindred spirit in some sense. you couldn't really put your finger on it, so you mostly dismissed it as a crush on a cute omega. but it did nag you a little bit.

≿━━━━༺❀ aoi ❀༻━━━━≾

✿ you were the only child of a famous art-dealer and a baku. after your mother's death, you were tasked with her duties to look after the city and their dreams, which made you appear rather lazy, though endearing to the general population.

✿ you were 17 at the time, a year older than aoi. your mother had died exactly a decade prior, while aoi had been in the capital for almost two years.

✿ you were sleeping at the river bank, though really you were "working". aoi came to the same river bank to sketch, noticed you, and decided to sketch you. that night, while you were working again, you happened upon a dream that featured... you. that's how the two of you became aware of each other, but it wasn't until the next day that the two of you actually met at the river bank.

✿ the two of you would often "meet up" at the river, where you would get on with your individual work. the two of you rarely talked, but seeing as you were sleeping most of the time it wasn't a surprise. but it was a nice routine, that neither of you wanted to break.

✿ aoi found you very vexing. but also pretty, which made you a rather effective muse for his work. but you were still asleep almost every time he saw you, which he absolutely hated. at first anyways. weirdly enough, after a while he didn't much mind anymore. something about aoi made his dreams in particular very appealing to you. after the first night, you realized you'd visited his dreams plenty of times before, even for non-nightmare purposes. his subconsciousness drew you to him for some reason.

≿━━━━༺❀ yura ❀༻━━━━≾

✿ you were the only child of a famous art-dealer and an akurojin-no-hi. you were most known for your habit of walking around the city on rainy nights, something you inherited from your mother. you think so, anyways.

✿ you were a mere 20 years old, though often you felt like you were far older. being basically just a living soul, you were extremely close to your past lives. yura was over a thousand, though technically to him you'd already met a long time ago.

✿ you were on one of your usual walks, it was a night and it was raining. everyone who knew you was expecting it. what no one expected, not even you, was the compulsion to head for the mountains. there, you ended up at a temple, and the two twins there saw you and invited you inside. something made you take that offer, even though similar ones had been made a million times before and you'd accepted none.

✿ after that you often ended up at the shrine, sometimes unintentionally, sometimes not. sometimes it wasn't even during a rainy night. regardless, you ever only accepted yura's offers to come inside from the rain.

✿ yura realized right away who you were, someone he had loved so dearly in the past had come back to him. his dear alpha. you didn't recognize him, but just being near you was enough for him, feeling your warm flames. yura felt like home, strangely enough. you felt like you knew him, like you should know him. you concluded that it was your soul who knew him, and that was why you let him invite you inside. so, you let your soul guide you back to him whenever it desired.

Alpha!Rei and Alpha!Koga x Omega!Gn Reader Ramble

tags/warnings: reader has two holes, abo, breeding, anal sex, biting, knotting, double penetration

Imagine being in a relationship with Koga, but one day you go into heat while Koga is out working a job. You’re sobbing, begging for an alpha, and then Rei happens upon your trembling form, just begging for an alpha to come and knot you. He knows that Koga wants to make you his mate, but you’re so full of desire…Rei can’t help but try and ease your pain. Nevermind his own tucked away desire for you.

He fingers your soaked hole, scissoring you open even though your slick is more than enough to get you wet. While you moan, he dials up Koga and lets him hear your cries and pathetic begging noises. After Koga gets to hear your pleas for him, Rei adds on that if he doesn’t get here soon Rei will knot you and knock you up for himself. It’s mostly a threat to make sure Koga gets here asap, but Rei wouldn’t mind taking you for himself either.

He intended to only use his fingers on you, but you’re still so needy even after making a mess on his hand. You keep grinding against his palm, begging for more, and Rei, as good as his self control is, decides he may as well help you out completely. He pushes his slick covered fingers into you anal hole, and spreads you open to get ready for him. Turns out he didn’t even need to do that either, because your body soon gushes out more slick from your other hole. It’s a huge turn on, and Rei’s inner alpha claws out, unable to wait to plunge into your ass. His cock frees itself from his pants and he practically slams himself into your ass. You cry from the sudden penetration, but it’s mixed with the pleasure you’re chasing desperately.

The entire time he fucks you roughly, you’re begging for more, because you know him fucking your ass will barely satiate your needs. Your other hole keeps clenching around nothing, even as you orgasm over and over. Even when Rei growls and pushes his knot into your tight ass, the heat in your body isn’t going down, and you know you need someone to knot you and fill your womb with seed, but Rei won’t do that, not when Koga wants to do that himself.

That’s when Koga finally bursts in, more than angry that Rei has been touching his omega. Of course, he feels terrible he was away when your heat started, but he’s going to make up for that now. Rei’s knot is still stuck in place inside your ass, and though he only pleasured your other hole with his fingers, it’s puffy and swollen just from how wet you are. Rei wraps his arms around your abdomen and pulls you towards his chest, letting your legs spread for Koga to mount immediately, saving his snarling for later as he focuses on making you his. You sob, finally getting what you need as your cunt clenches around his cock. Koga pounds you with no mercy, howling loud enough for people to hear and saying how he’ll stuff you with his pups. All you can do is agree with everything he says. You want his seed, his kids, his knot—absolutely everything will leave you a wreck.

Rei watches and breathes heavily against your ear as Koga continues pounding your omega hole, your sobs for an alpha making something stir inside him. He’s a bit jealous that Koga gets to claim you, especially since you’re almost certainly going to get pregnant and be marked as his mate, and feels his cock harden again, so he thrusts up as much as he can while still knotted inside you. What if he could be your alpha too? Why can’t he also get you pregnant with pups? He inhales your pheromones as Koga plugs you up and shoots spurts of his seed straight into your womb.

They both wait until you’ve all calmed down and their cum has settled inside you before talking. The two alpha’s cocks are still inside you, and neither want to give you up, so you suggest they share instead. What better way to ride out your heat than being fucked twice as much? Though Koga grumbles a bit, he obliges since he wants to make you happy. He and Rei both sink their fangs into different sides your neck at the same time, making you belong to both of them. Now that they’ve both claimed you though, Rei pops his knot out to push into your other hole and join Koga, wanting to start work on you bearing his kids. Needless to say, the two UNDEAD members won’t be taking their hands off you until you’re completely filled.
