[Can't Control Myself]
Katsuki is an alpha hero trying to rescue those in a disaster zone when he's suddenly struck with a special scent. Immediately, he's obsessed with finding his mate.
#bkdk #abo #feralbehavior
Katsuki licked his lips, inhaling deeply as bodies moved around him. He wiped the sweat from his forehead and flicked his eyes in the direction of the scent.

/Fuck/.

Spiced honey coated his palate, warm and sweet, and his fangs were already descending. What /was/ that?
The last building had collapsed a little over an hour ago, and he’d gotten everyone he could see out of harm’s way; the perpetrators were already in custody, but the streets remained pure panic. He needed to focus.

But that /smell/.
He whipped around again, crimson eyes searching as he ground his teeth down hard, trying to will away the newfound ache in his jaw. Something inside him /needed/ to find the source, felt like he might die without it.
Someone slammed into his side, nearly throwing him off balance, and he outright growled. The poor lady gasped, wide-eyed.

“I’m s-so sorry, Mr. Dynamight, sir! I’m just—I’m trying to find my son…”
Katsuki took a deep breath in and out through his nose, working to calm himself the fuck down. This was his job. He was a damn /hero/. He couldn’t get distracted for some sweet-smelling piece of ass— if that was what that was. His body sure seemed to fucking think so.
“I’ll help,” he gritted out, though he was sure he looked no less terrifying than he had a moment ago.

His entire body was tense with a need to hunt. He didn’t want to look for some lady’s son; he wanted to look for his mate.
Wait... /Mate/?

What the hell was wrong with him?
The woman looked terrified, but before she could respond, a heavy arm fell around his shoulders.

“Actually, I’ll help her. Dynamight, why don’t you go and check in with the unit? See where they could use you most right now.”
Kirishima shot him a wide smile that didn’t reach his eyes, and Katsuki sent him a thankful look in return.

He was definitely pumping threat through his pores.
He nodded and turned around, making his way back toward their predesignated meeting point. He’d been walking for a good few minutes, trying to clear his head, before that scent spiked again. His nostrils flared, throat burning.
/Mate/, his alpha seemed to scream inside him, clawing at the insides of his chest.

It fucking hurt. His vision swam momentarily, other senses seeming to burst in their intensity.
The crowds were beginning to thin. The screaming had died down. People were mostly gathered with their families or with policemen, wrapped in blankets as they sipped warm drinks and answered questions.
Katsuki didn’t spot a single person who looked as intense as that scent; it was screaming at his instincts, forcing him to respond...growing stronger.

There were still a few heroes digging through rubble, searching for those who were likely lost causes by now.
The movement of a beam led to something of an avalanche—additional support beams began to tumble, large hunks of cement slamming to the ground.

Something sour rose within the scent he'd been tracking—/distress/.
Shit! Katsuki was moving before he was thinking, blasting himself toward the disaster zone and frantically searching for the source. The scent was so fucking /strong/ here—he had to be close.

/Mate/!
He was fucking drowning in it. He threw pieces of flooring, furniture, metal, stone—whatever his hands could reach as he single-mindedly focused on the smell.

A quiet whimper met his ears, and he fucking /roared/.
Katsuki's throat was raw and his teeth were bared when he finally blasted through another mass of debris, trying to dig deep enough to find—

"Mate," he breathed.
His heart throbbed in his chest, completely panicked at the limp form of the boy before him. Forest colored hair was matted with blood, freckled cheeks slack with lips parted and breath moving raggedly between.
“Shit."

His lungs seemed to hold his oxygen hostage as he removed the last of the wreckage that held him. He reached forward to slide one arm behind his back and the other under his legs, lifting him gingerly.
A low whine met his ears, and he clutched the omega closer to his chest. Frantically, he nosed at his sun-kissed cheek, his throat, exuding as much scent as he possibly could, needing this omega to smell like him, /needing/ to comfort, even going so far as to fucking /croon/.
/Mate, mate, mate, mate/…

His alpha was fucking losing it.
“Oh, Dynamight! Hey! When you’ve—” Thunderfuck brushed his arm, and Katsuki snarled. He snapped his teeth at him as he growled violently, body trembling with the need to protect, to keep anyone from coming anywhere near his omega.
“I— sh-shit!” Denki stepped backward, palms facing forward in surrender. “It’s just me, dude. I’m not—” His nose twitched, eyes widening as he looked at the unconscious figure in Katsuki’s arms, then back to Katsuki’s face. “I won’t hurt him, man. I swear—”
Katsuki snapped at him again, low growl growing persistent in his chest as his fangs descended. His entire body felt tight, coiled, ready to spring at anyone who got too close. He brought the omega closer to his body, lifting him higher so his face was almost in Katsuki’s throat.
Mine. My mate.

His rib cage broadened, chest puffing as nearly every part of him flexed, posturing, warning.

Until a pang of hurt in Denki’s scent practically slapped him in the face. Katuski blinked, deflating.
“Fuck, I’m—” He opened his mouth to apologize, to explain… but the second he did, that sour scent filled his throat, and he felt his alpha’s fear and anger rebuilding. He was going to go feral. He could feel it.
He needed to get the hell out of here before he did something even more stupid.

Denki backed up further, palms raised and voice soft. “It’s /okay/, Bakugou. No one is going to hurt him. Let’s take him somewhere safe, yeah…?”
He exuded a comforting scent, a beta so non-threatening that he may as well have been omega. Somehow, it seemed to help. Katsuki felt his defenses slowly relaxing as he watched his prior classmate watch him. He swallowed thickly, unsure what to do, not trusting himself.
The body in his arms was limp, but breathing, and Denki was right—he needed to get him help. His mate needed help. Katsuki didn’t want to fail him, /couldn’t/ fail him.
But he couldn’t think straight enough to take him where he needed to go, couldn’t remember where the medical tent was or how to get there, couldn’t make heads or tails of the primal thoughts filling his brain.
“Show me,” he gritted. His voice was raspy and raw, as though he’d been screaming— had he? His throat was on fire, glands aching.

Denki nodded slowly, then turned to walk in the other direction, only peering over his shoulder to ensure that Katsuki followed.
TBC!

Update incoming for this thread, but before that - a quick author's note, apology, and PSA:
Katsuk couldn’t remember much after that. His mind was riddled with a feeling of fight or flight, of pure and primal desperation. All he knew was that he’d gotten his mate to an ambulance somehow.
He'd snarled at anyone who tried to touch him, until Kaminari explained that the guy might die without treatment—they didn’t know what his injuries were, after all.

That scared Katsuki more than the foreign hands.
He allowed their exam, so long as his omega remained in his lap. Katuski did his best to pump comforting pheromones, protective ones, so if his mate woke up at any point, he’d know he was safe, that Katsuki would take care of him.

And Katsuki watched them carefully.
Every touch had to have a purpose, required permission. His bared fangs were enough to prevent any sudden movements.

They bandaged his mates head, gave him something through an IV, but Katsuki wasn't totally aware of what was going on.
His logical brain wasn't working, wasn't following their tasks and objectives. Instead, it processed the flashing lights through the windows, the nearness of their fingers to his omega's skin. The shallowness of his omega's breath, and the sour stench that hovered in the air.
It was obvious that his mate needed him. He found himself rubbing circles over the glands on his wrists, nosing the one at his throat. Anything he could do to help relax him, to help the omega to heal. Anything, /anything/.

Katsuki was in a daze. He didn't know what to do.
At some point, they’d made it to a hospital, and Katsuki had roared when the nurses tried to pull his hands to examine them. Katsuki's fingers were firmly planted around his omega’s body, and he wasn't releasing them for anyone to 'take a look.'
They tried to reason with him—something about blood, tendons. He didn’t care. They could cut his fingers off for all it mattered. He was /not/ leaving his omega alone, not for anyone or anything.

But something pricked at his shoulder, and then everything went black.
***

Katsuki felt like he’d barely closed his eyes when they opened again. The room spun; every sound was too loud; every scent blared in his nose. As he registered his environment, he recognized his mate’s scent again immediately.
It was different now—more honeysuckle and less panic—and his shoulders relaxed slightly. He was curled around the guy, his forest waves now soft and unmatted, clean and pretty. Katsuki buried his nose in them and sighed.
Relief was a physical force that melted through his body. He relaxed back into his cuddled state, tucking his face into the crook of the guy’s neck with his arms slung around his waist.
The breath moved evenly through their chests now, soft and quiet—a vast improvement from the quick, ragged, and terrifying pace of hours(?) or days(?) ago. Katsuki had no idea how much time had passed, and he didn’t care, either.

He was just glad the omega was alright.
So much of his body ached, and he couldn’t imagine how the other must feel, with the way that Katsuki found him, so he did his best not to disturb him too much while still satisfying his curiosity.
Katsuki rubbed his nose against his sweet scented gland, feeling along his mate’s abdomen as he elicited more of this new and pleasant, happy scent. His fingers felt stiff; he could feel the bandages that decorated them...
likely cut from his reckless digging through the rubble earlier, but it didn’t stop them from exploring.

Katsuki’s lips curved smugly when he grazed fingertips over the omega's belly, muscles easily palpable through his gown. Of course his mate would be fit and strong.
Katsuki was an ideal alpha—he’d have an ideal omega, too.

He was only slightly smaller than Katsuki himself, perfectly designed to fit right within his hold. Like a puzzle piece. The other half to a whole. A whole Katsuki had absolutely no qualms about keeping forever.
Said omega hummed in his arms, snuggling back, closer to his body, and Katsuki closed his eyes again, satisfied that he’d done his job.

Mate was safe. Protected.

The omega turned his head, almost instinctively, to brush his cheek to Katsuki’s—scenting him.
“Alpha…” he murmured, and heat flooded Katsuki’s entire form.

His alpha suddenly wanted to respond—to wake his mate entirely with tongue and teeth over the sensitive gland on his throat, with a knot in his ass and a new mating bite fresh for everyone to see.
The call upon his baser instincts was difficult to fight, but they hadn’t even spoken. Katsuki tried to keep his head about him, tried hard to force his alpha down. He swallowed thickly and nuzzled back against his face before pressing his lips to the corner of the omega’s jaw.
“Mine…” he whispered in return. His mate hummed happily, as if in agreement.

Katsuki crossed his arms over his waist to squeeze him in more tightly. His legs slid behind the omega’s, wrapped around him with as much of their bodies touching as he could manage.
He needed to be as close as possible, to satisfy as much of his urges as he could without crossing that invisible line he’d drawn for himself.

Still, he couldn’t go without forever. The firm arousal between his thighs was proof of that.
Surely, when this omega woke, he’d realize exactly what Katsuki had: they were fated. This was unavoidable.

This omega was undeniably his.
TBC!

Next time: Izuku wakes up AND we get his POV.
👀Hope you stick around for it!

Day 3: Date Night, Bathing, Arguments
[sfw, fluff again lol]

Izuku dove, barely missing the purple slime spewing from the villain’s mouth, but the speed of his evasion distracted him from his surroundings.
He'd rolled right through the disgusting old sludge from about three attacks ago.

Crap!

Not only was his costume dirtied, but it had gotten on his forearms, and his head felt sticky as though it was in his hair.

Double crap!
He whirled around and threw a hard smash at the villain—probably harder than he needed to, honestly—knocking him out cold and /maybe/ bruising his skull a little.

He hurriedly threw a set of quirk cancelling cuffs on the creep and then pulled out his phone to check the time.

Day 1: Morning [sfw, super fluff]

Izuku groaned as he rolled over in bed, unsure why his lids felt so heavy if he'd woken up on his own. No alarm, no commitments; he could have slept as long as he liked, and yet…
When he wrenched eyes open, he found the yellow-blue color of barely there sunrise beginning to creep between the blinds. He sighed and pulled the covers up to his nose, huddling into them. Sleep. He needed more sleep.
A warm palm slid around his waist, body heat pressing to the length of his spine, his behind, even the backs of his thighs as Katsuki curled around him entirely, and he hummed with happiness, that low-building giddiness not something he thought he’d ever get used to.

[You're Gonna Be The Death of Me (in such a good way)]
bkdk, nsfw, faery!izuku, barbarian!katsuki
bk finds an injured faery & can't help but take him in
💚

“Oi.”

Izuku scrunched his eyes, furrowed his brows. The sound seemed far away, as though his ears were filled with cotton.
He seemed to be listening.

“Shit, Izuku. It means… ah,” Katsuki didn’t know how to say this shit. He was so fucking awkward and uncomfortable about these things. He’d never felt this way before, and he—
“Just say it!” Izuku shouted at him, full-on sobbing, and Katsuki’s eyes blew wide.

“I think I love you,” he blurted, spitting out the first words that came to mind.

Izuku immediately froze. His tears seemed to have disappeared instantaneously as he held his breath.

[Take my fucking bento, asshole] ABO BKDK

in which QL, MS, Omega Izuku accidentally asks Katsuki to court him without knowing it😅
Izuku had forgotten his lunch at home, and he was really starving. Seated at a nearly full table with kids who otherwise ignored him, he reviewed his hero notebooks to keep his mind off the painful hunger in his gut.
Unfortunately, his stomach would not be ignored. A loud growl brought eyes his way, and he buried his face in his hands to avoid the stares, face beet-red.

Until a clattering sound prompted his forest eyes to raise... finding a bento before him, unopened and smelling divine.

OK so I'm in the mood to write a medical AU?
Katsuki is a trauma surgeon
Izuku is a mid-level surgical resident
IDK what's gonna happen in the plot yet but here we go
Here are some of tags I *suspect* will be true:
Medical AU
BKDK (duh)
Unprofessionalism (attending/resident relations)
Scientific gore? IDK not horror but surgery, y'know?
Prob dekubowl stuff bc it's me
Prob NSFW...bc me
?Angst
!!Happy ending
Izuku powerwalked his way into the hospital, running late as usual. He wasn’t sure when that became his norm, but it was. Last year, he was twenty minutes early, had his charts reviewed, his notes written, and his presentations prepped before anyone else even arrived.
