abo hcs, might end up being a thread/fic/cohesive story but idk, alpha katsuki and omega deku, female body parts for deku/trans deku mayhaps ?

- bakugo is just walkin through the grocery store n turns a corner and sees the cutest little omega ever and then BAM izuku's eyes turn golden and Oh Fuck Bakugo Just Imprinted This Omega

- Oh Shit What Am I Supposed To Do
- izuku can't tell his eyes changed but the alpha smells Really Fucking Good and something in his brain switches and he's up in the alpha's neck scenting him
- bakugo just lets him bc now they're basically destined to be together

- izuku snapping out of it, finding himself being dragged along to a less busy aisle of the store by a tall strong guy who's giving off a very protective-alpha scent
- he just kinda lets it happen because the alpha smells like him and his mind is still really foggy

- katsuki realizing the little omega isn't on hormone-autopilot and telling him that he imprinted on the omega but Not To Panic bc he promises he won't hurt him, izuku freaks out + starts crying and katsuki just shushes him and holda him to his scent gland on his neck

- izuku tells him he doesn't have any place to stay because his dad left when he presented as an omega and his mom recently passed and he was couchsurfing
- katsuki offers him a place to stay and izuku reluctantly agrees

+ izuku doesn't know this alpha but he smells good and is letting off calm pheromones so he says Fuck It and goes to the alphas house with him
- katsuki, ever the gentleman, offers to buy izuku heat suppressants since he can smell izuku letting off pre-heat pheromones

- izuku agrees + doesn't have a heat for the first time in nearly 10 years, he's really agitated and fidgety and still makes a nest in katsuki's room when the alpha is gone for work
- katsuki comes home to an asleep omega nestled between a bunch of blankets and clothes

oh uhhh this was supposed to be hcs i'm so dumb
- hc that omegas get chumky and lose muscle mass in exchange for fat, and that their hips and thighs get wider and they grow breasts (female omegas just get bigger chests and males have small ones, just large enough for the organs)

- male omegas' penises shrink + grow vaginas, they're normally just little holes without lips but sometimes their genetics get messed up n they get pretty pussy lips hehe
- female omegas often don't grow very tall (only about 5'2") but male omegas are even shorter (4'9"-5'0")

- male omegas aren't uncommon, but are in high demand bc a lot of large countries have lots of female alphas (and most alphas are straight)

- trans omega deku presents around age 11 and panics bc his body is suddenly producing lots of testosterone (his secondary sex recognized him as male and realized the hormones weren't correct and his body couldn't risk hurting any pups so it fixed the hormones)

- izuku's clit grows large enough that it's about the correct size a male omega's penis would be + his dysphoria isn't bad at all because his other male omega friends' bodies were the same as his own

- omegas without an alpha would often help eachother through their heats (they do produce knots, they're just incredibly tiny and don't provide much relief, but if two omegas help eachother often enough then the receiving omega's body adjusts to be satisfied by the small knot

(yes even female omegas can produce knots, don't judge my logic)

ooh a fun rarepair thing,
- o!jirou helping o!deku through his heats (deku often stayed with her since he was basically homeless + they were good friends), the first time she helps they're both worried deku got pregnant (they were both newly presented,

and it was very uncommon for omegas to be allowed a proper sex education)

+ deku and jirou both thought deku was pregnant for a few months, but then deku had another heat and they were both super relieved (jirou had only had one heat, when she presented, and deku had 2: when he presented and when jirou helped him, 3 if you count the latest one)

n e ways back 2 bkdk
- katsuki notices izuku forgets to feed himself so he cooks him food and the omega purrs and lets off happiness pheromones subconsciously + katsuki nearly cried (from happiness) the first time he found deku like that

also i'm sorry i switch between names for everybody aaahh
for those of you who may be new to the fandom/just don't know, bakugo/katsuki/kacchan are the same person, and midoriya/izuku/deku are the same person (katsuki is the blonde meanie and izuku is the grean-haired protag)

- izuku forgets to take his heat suppressants for a few days and it comes on really slow, he and katsuki had been living together for about a year at that point and izuku was actually the one to ask katsuki out, so they had been dating for 3ish months when izuku's heat hit

- katsuki notices the little whimpers that his omega lets out in his sleep and his richer scent, and realizes that Oh Fuck He's Going Into Heat
- izuku doesn't notice until later that day when he lets out a bunch of slick for the first time in a year and panics,

because Oh No My Alpha And I Haven't Talked About Mating
- katsuki can tell izuku is stressed and nuzzles his neck to calm him, lapping gently at his scent glands a few times to let him know that everything is okay and that his alpha will protect him

- they talk it out and they're both okay with being heat/rut partners, katsuki goes off and buys condoms and lube and alpha birth control + requests two weeks off work (heats normally only lasted 5 or 6 days but this was the first heat his boyfriend was having in a year,

so he just wanted to be safe)
- izuku's prime heat finally hits and it triggers katsuki's rut. the two prepared easy food together since neither of them knew how much time they'd have between sessions to eat
- izuku screams and cried for katsuki to just /hurry/,

but katsuki knows the omega hasn't been prepped or had sex in over a year so he forces his rut to the back of his mind to prep his tiny omega as carefully as he can
- izuku is hella greedy and grips katsuki to the point that there are tint bleeding nail marks on the alpha's back

- izuku's hest lasts 8 days and katsuki thinks he forgot to wear a condom and take his pill one session (izuku woke him up by bouncing on his half-hard dick) and realizes in a panic that he /may or may not/ have gotten his boyfriend pregnant

- a few months later, katsuki is holding izuku and rubbing his hand over his omega's stomach and feels a tiny bump and sits up. izuku smells how distressed his alpha is and panics
- katsuki tells his boyfriend that Holy I Think We're Gonna Have Pups

- izuku os hysterical at first because he's only 22, he's too young to have pups, but eventually accepts it and becomes very overprotective of his unborn pups, going as far to growl at his alpha a few times when he's in bad moods (he always profusely apologizes, though)

- some preggy sex happens and izuku slowly gets addicted to the feeling of his alpha's knot popping in and out of his tiny hole (they're always very cautious and aware of izuku's tummy, though)

- they have a litter, two girls and a boy, triplets (bakugo says his eyes were brown before he presented and his eyes turned red. all three pups have dark caramel brown eyes, heavy freckles, and one girl and the boy have blonde hair and the other girl has green hair)

- izuku and katsuki end up moving to a bigger house so their pups can have room to grow
- a few years pass, izuku is pregnant with another litter, all three of their (already born) kids have presented (the two girls are betas and the male is an alpha), and things are looking good

- katsuki gets a new job as a lineman [working on telephone poles and down electrical wires, basically] and it pays well, izuku is a cam boy (katsuki knows about it and helps make sure none of their kids see their mommy like that + helps his omega set up the neutral background)

+ turns out, lots of rich alphas like seeing a pregnant mated omega fuck himself. it pays really well and izuku decides to do the streams and videos twice a week)
