Katsuki’s a grown ass man when a five year old fucks up his life with one stupid statement.
“You smell like Christmas!”
He’s heard a lot of crazy shit before and this shouldn’t even make the list. The concept isn’t too far off, if he thinks about it hard enough. Katsuki has heard his Alphan scent is something akin to roasted cinnamon, so: cinnamon, smoke, fireplace, Christmas. It tracks.
The unexpected comment coming from a five year old who looks up at him with glee still catches Katsuki completely off-guard and makes him freeze in place.
Until it occurs to Katsuki that he may have not been the only one to hear. He whips around to look at his teammates and hates what he sees.
There’s a second of silence, amongst the Pro Heroes at least. The children continue to babble and pull on the costumes of the Pro closest to them, but his teammates are all ears, all eyes on him. They stare, eyes bright with shock and something way too close to absolute elation for Katsuki’s taste. He glares back at them, silently warning, ‘Don’t you dare—’
Round Face breaks first. A giggle tears its way out of her chubby cheeks and soon the whole team is laughing hysterically. Even the normally shy Earjacks bends at the waist and presses both of her hands to her mouth to keep the laughs in.
“Christmas?” She chokes on the word.
“CHRISTMAS!” Pikachu howls with absolutely no restraint.
A new round of laughter shakes the group and Katsuki feels himself heating up in anger. Definitely anger. Not embarrassment.
“Shut the fuck up!” He yells like he’s a teenager again.
“Ooooo, teacher! Ground Zero said a bad word!” The same kid as before tattle-tales instantly.
“Bad word! Bad word! You said a bad word!” All the kids begin to yell in a half sing-songy way. It creeps Katsuki out how in sync they all are. Fuck, he never wants kids.
He shouldn’t be here in the first place. Ground Zero doesn’t do school presentations about what it means to be a hero. But business has been slow. Real slow. He shouldn’t be complaining about the record-low crime statistics because it means heroes (especially Katsuki who still see-saws between being first and second in the rankings) are doing their job. At the same time, he still wants to have a job. One with kicking villains’ asses and saving people from danger. Meet-and-greets don’t count as being a hero.
“I’m so sorry, Mr. Ground Zero,” a teacher apologizes as she attempts to wrangle the closest batch of kids away from him with her quirk-enhanced elongated arms. They still continue singing.
“Bad word! Bad word!”
Katsuki closes his eyes and counts backward from ten. Nevermind, make that twenty.
The extra ten seconds do the trick.
“It’s fine,” he says through only slightly clenched teeth. “And...I’m sorry for saying a bad word.”
The children that are still paying attention cheer, but the majority of them have already moved on. They continue to busy themselves by bombarding the other Pros with questions, much to Katsuki’s content. His team immediately becomes preoccupied with the children again. Katsuki even tricks himself into thinking that they’ll forget this whole thing by the time they go back to the agency.
When they arrive back, Katsuki’s desk is covered in Christmas decorations.
“How the fuck!”
“Bad word! Bad word! You—” ScotchTape and Pikachu cut off with screams of terror at the look on Katsuki’s face, the latter going as far as to add, “Don’t hurt me!”
“We just got fucking back!” Katsuki snarls as he stomps over to his abomination of a desk.
“The wonders of technology,” Raccoon-eyes sighs dreamily and Katsuki can hear the snaps of her cell phone camera behind him.
Fucking—. Stupid extras and their stupid groupchats. Katsuki reaches out and grabs a particularly long string of garland and tugs it off his desktop screen only to release copious amounts of red and green glitter. He swears again.
“Where did you even get all these damn decorations, it’s March!” Katsuki turns to snap some necks, but all of his fellow Pros are gone. Damnit. They know him too well.
The rest of Katsuki’s day is uneventful. He cleaned his desk, wrote out his report (why the hell do they have reports for school visits?), and made his way home. The small house is quiet when he gets back, like usual. He starts the rice and preps the meat and veggies for the meal he’ll cook later, but places the mise en place back into the fridge for now.
His mind is too active right now and he heads down a floor to his in-home gym for a much needed workout therapy session. Thirty minutes of cardio and eight reps of weight lifting in, and Katsuki finally stops. He gives out a sigh, eyes closed. He remains lying flat against the padded bench of his bench press.
It was just a kid saying stupid shit and his friends laughed because it’s funny. That’s all. Yet Katsuki Can’t. Stop. Thinking. About. It.
Not about the Christmas comment itself, but rather the whole string of insecurities the comment stirs up.
Katsuki’s turning thirty this year. He’s not the same brash, loud-mouthed Ground Zero he was when he first graduated UA and became a side-kick. It took some time, but Katsuki’s cultivated an identity for himself that’s far more complex. Ground Zero, Symbol of Victory, is as protective as he is aggressive. Efficient as he is blunt. Respected as he is feared.
Except, he’s really not that feared anymore. The interns jokingly refer to him as a “grumpy Grandpa,” despite only turning thirty. Villains avoid him, as they should, but not with anymore fear than they would any other hero. Katsuki used to be banned by the agency from going to any event with young kids for fear of someone snapping a picture of Katsuki making some kid cry. Now, he apparently reminds those brats of fucking Christmas.
Not being feared isn’t what bothers Katsuki. Not really. He’s worried about what that loss signifies. Sure, Katsuki’s still top of the charts, but he’s hyper-vigilant of the fact that he’s not at the top of his game anymore. He reacts slower than he’s used to, just by a beat. That’s all it takes to make a mistake. While he hasn’t made many, or any really, big mistakes yet, he can feel the “yet” weighing a little more heavily on his shoulders with each passing day.
He’s used to being the best. He needs to be the best. Only, he’s technically been the best for a while now. He made it to the top of the charts. He’s been the number one hero before. It doesn’t feel like it’s enough anymore. He wants something new. He wants a challenge.
There’s movement above him and Katsuki’s eyes snap open immediately.
They open to see a sprig of green being held over his face by a pair of scarred fingers.
“Oh no,” the voice behind him whispers, “mistletoe! Guess we have to kiss now?”
Katsuki growls, upper lip lifting to show off sharp canines. “Shut the fuck up, Deku.”
As Katsuki sits up, Deku steps back posture changing immediately. The Omega’s normally earthy and crisp scent turns murky and dank with worry before Katsuki has a chance to turn around and see the confusion and hurt in his mate’s eyes.
“I’m sorry, I didn’t—”
Katsuki’s chest feels tight as his inner Alpha rumbles with disapproval. He’s being an ass and that doesn’t fly. Not when it comes to Izuku. Not anymore.
“No, I’m sorry,” Katsuki’s quick to apologize. It’s taken years and lots of practice, but he recognizes when he’s lashing out as a means of distancing himself when he’s feeling insecure. “I didn’t mean that.”
Izuku’s face softens too quickly. Forgiveness comes easy to him. Katsuki envies that and loves his mate all the more for it.
Deku looks down at the piece of mistletoe still clutched tightly in his fingers before he holds it up half-heartedly. “So, no kiss?”
Katsuki rolls his eyes before holding out an arm to his husband. Izuku smiles as he grabs onto his husband’s wrist and uses Katsuki’s arm like a life-line, pulling on it until he’s in Katsuki’s space, half-bent over since he’s standing and Katsuki’s still seated. Their lips fit perfectly against one another, the key to Katsuki’s lock. For the first time, Katsuki’s mind stills, the burn of his dissatisfaction withering down to nothing but embers.
He’s about to turn this kiss into a full-on make out session since he seems to be nothing more than a moody teenager today, but Izuku pulls away. Katsuki can’t help but growl and Izuku chuckles in return.
“You sound disappointed, Kacchan.” Izuku teases as he looks down at Katsuki.
“And what if I am, nerd?” Katsuki smirks, head tilted back. He wraps an arm around Izuku’s waist to pull him in closer and the other instinctively wraps his arms around Katsuki’s neck.
“Wanna talk about it?” Izuku whispers carefully. Katsuki rolls his eyes.
“‘S stupid,” Katsuki mumbles into his mate’s shirt as he presses himself against the Omega’s strong abs. The thought occurs to him: how it would feel for Izuku to have some pudge, for Katsuki to settle his head against a smooth, round belly. Weird thought, but okay.
“I doubt anything you think could be stupid.”
Nerd really had no idea what was going through his head.
“Did the Christmas comment really bother you that much? Everyone said you got upset after they decorated your desk, but it was just a kid saying something funny, wasn’t it? Is there something wrong? Can I help?”
“You talk too much,” Katsuki can’t even begin to sound upset about that fact. “Seriously, it’s nothing.”
“Ka—”
“Since when do I smell like Christmas? When did I go from Badass to fucking Santa Claus?”
“I think you’re sexier than Santa.”
“What the fuck, I better be.”
Izuku smiles as he suddenly sits on Katsuki’s thigh. He rubs his face against Katsuki’s neck, tongue darting out to lick the set of teeth marks that surround Katsuki’s scent gland. Izuku’s chest rumbles in a purr that sends satisfaction thrumming through Katsuki’s bones.
“You taste better, too.”
“How would you know what Santa tastes like?”
That makes the Omega laugh but he also pulls away, much to Katsuki’s discontent. Izuku’s eye contact is steady and soothing. “You’re still a badass, Kacchan. You’re the number one hero.”
“No, you are right now.”
“Then you’re my number one.”
“Tch,” Katsuki clicks his tongue as he turns away. He’s starting to feel very warm in the face and he can’t help but notice how nice Izuku’s ass feels on his thigh. “Like I said, it was stupid. I fucking hate kids.”
“You don’t mean that,” Izuku mumbles, again at Katsuki’s neck. This time he’s kissing a trail from Katsuki’s collarbone to his hairline, stopping just above his ear before dipping back down to nibble at his chin.
“Fuck ‘em,” Katsuki smirks as his own hands make their way under Izuku’s shirt and into the elastic of the man’s gym shorts. “Never want one of those snot-nose bastards.”
Again Izuku pulls away and Katsuki growls in frustration. What’s with the damn teasing! Only, this time, Izuku is frowning not smiling.
“What?” Izuku asks.
Katsuki frowns too. “What?”
“What do you mean you don’t want kids?”
“Hah?”
“Do you really not want kids?”
“Eh?”
“Do you not want kids, Kacchan?”
“I—” Katsuki expects himself to immediately say no, but one look at his upset Omega has his inner Alpha whining.
“Kacchan—”
“I don’t know. I—I haven’t really thought about it much. Kids are annoying.”
Izuku’s frown deepens. “Kids can be difficult, yes. But this is important, do you want kids?”
Again, Katsuki expects himself to answer no...but he can’t. He’s eye level with Izuku and he can’t help but imagine Izuku round with their pups, the earlier thought of Izuku’s bulging stomach suddenly very clear in his mind. He can almost imagine scenting their child, together with Izuku. He imagines their combined pine and smokey scent and the idea of it being Christmas in their house everyday. Katsuki sighs in relief at the thought.
For the first time in a long time, Katsuki feels light. His shoulders rise from beneath the weight of not being the best, at no longer being challenged. Because Katsuki would be a kickass father, even to a brat as troublesome as his and Izuku’s would surely turn out to be.
Izuku’s still staring, his eyes a swirling mix of worry, disapproval, and uneasiness. That won’t do.
The Alpha is immediately purring to soothe his mate, bringing Izuku in close to him with a hand on the back of his neck. Katsuki can feel Deku being stubborn and trying to stop Katsuki, but he relents nonetheless.
“I think I can be persuaded into it.” Katsuki nips at his own set of teeth marks on Izuku’s neck, before he kisses the mark passionately. Izuku gives out a stuttered breath.
“How—how so?” Izuku’s voice is low, lower than his normal speaking voice and Katsuki can’t help but grin into skin of Deku’s shoulder. He can already smell his Omega’s slick.
“Heard making a pup can be pretty fun.”
“Yeah?” Izuku asks breathlessly. He’s shifting on Katsuki’s lap and the Alpha’s tempted to move him to the other thigh so Izuku can feel Katsuki’s hard-on that’s hardly hidden in his sweatpants.
“How about you tell Santa what you want?”
“How—how about—” Izuku pauses to gasp when Katsuki gives a particularly sharp tug of Izuku’s earlobe with his teeth. “Kacchan, breed me.”
Katsuki’s growls in approval, quickly moving his hands to grip beneath both of Izuku’s thighs. He lifts the muscular man with absolute ease as he stands. He turns and lays Izuku against the bench he’d been sitting on a moment ago. Katsuki’s a little too rough with the gesture but his mate only preens in approval.
“You’ll look so good full of my pups,” Katsuki says mainly to himself as he yanks on Izuku’s shorts and underwear, pulling them up and off, leaving Izuku’s legs hanging naked in the air.
Izuku moans when his hard cock twitches at the feeling of cool air. “Knot me so good, Alpha.”
Fuck, Izuku is so hot. Katsuki can hardly control himself when he goes for his own pants. They smolder slightly in his hands and holy shit, he really is just a horny teenager again.
He’s a little better than he was back then, seeing as even when he finally gets the tight pants off, he doesn’t immediately stuff his dick into his Omega’s dripping hole. Instead, he pulls Izuku’s legs onto his shoulders before dropping to his knees. He licks the excess slick that has coated his husband's legs, holding Izuku in place as the man moans and wiggles in frustration.
“Ka—ah!” Izuku doesn’t get the chance to complain as Katsuki is already licking further down, his tongue eagerly darting into Izuku as he devours him. Nothing tastes as good as Izuku so Kacchan’s happy when there’s another gush of slick thanks to his ministrations.
All the while, Katsuki’s fingers are hard at work having made their way down to Izuku’s dick and balls. They alternate between gently squeezing Izuku’s balls and rubbing up and down the Omega’s cock until it’s leaking as much as his ass.
“Please,” Izuku’s voice is already broken. Katsuki can hear his fingers scraping at the padding of the exercise bench, but Katsuki won’t be mad if his lover leaves marks.
When Katsuki stands, Izuku’s legs come with him, still balanced on Katsuki’s shoulders. The Alpha has perfect aim when he lines his dick with Izuku’s ass and enters him fully with one thrust. Izuku bends nearly in half with the motion and it sounds like Katsuki has pressed the air right out of him. They moan in tandem in the next second.
Damn, even after all these years Izuku feels so tight. He knows Deku must still feel full with Katsuki’s cock inside of him. His dick throbs at the thought.
His pace is steady; not brutal like it used to be. He focuses on the right angle first, grinning hungrily when he pulls that sweet groan from Izuku’s lips. He loves how his Omega’s voice gets deeper with pleasure; loves how rough his voice gets when Katsuki’s tortures him by pulling out slowly before he drives his dick in deep.
They both have the stamina of mad men and they usually change positions at least once, but tonight Katsuki’s in a hurry. He wants to see Izuku’s stomach bulging with his seed, even if he knows Izuku probably won’t get pregnant with this fuck. He’s not in heat and probably still on birth control, but soon.
Soon, Izuku will be round with his pups. Fuck, if they hurry, they can have babies in time for Christmas.
The thought has Katsuki thrusting much faster, harder. Izuku’s moans turn into pleas.
“Yes, Kacchan, yes, Alpha. Fuck me. Breed me. Please!”
Katsuki can feel his knot begin to catch and he knows Izuku can too. His Omega is meeting his thrusts, his fingers white where they grip the edge of the bench as he pulls himself further onto Katsuki’s dick. Fuck, he might even be using his quirk if the force is anything to go by.
That’s all it takes for Katsuki’s knot to catch, locking the two in place. Two half thrusts later and Katsuki is cumming.
“Deku!” He growls and he can hear Izuku cry out as he cums too.
Katsuki sort of registers the white stripes of cum that decorate his husband’s stomach and abs, but he’s much more focused on the swell of the Omega’s lower abdomen. He’s cum in Izuku plenty of times, but it has never looked this hot. Maybe because Katsuki is imagining that the swell is actually his pups already growing inside his mate.
With his knot inside Izuku, the mated pair are locked. For now. Katsuki pulls Izuku back into his lap as he none too gracefully falls onto the floor.
“Oof,” Izuku grunts from the movement. “Be careful, Kacchan. You don’t wanna hurt the pups.”
“What pups, Deku?” Katsuki laughs as he scents his mate’s neck without thinking about it. “You gotta stop the birth control first.”
Izuku goes eerily silent. Katsuki pulls away and stares into his husband’s eyes. Or, he tries to. Izuku won’t make direct eye contact.
“...you already stopped taking it, didn’t you?”
“Few weeks ago. I was going to bring it up before my next heat. We haven’t had sex in forever.”
“You little—”
“Mistletoe!” Izuku quickly redirects by holding the piece of greenery over their heads again.
Katsuki sighs and kisses his husband.
“You’re lucky I love you.”
“I know.”
“And that you’ll look sexy pregnant with our pups.”
“I definitely will.”
“Where did you get that thing anyway?”
“The mistletoe? Dug it out of storage.”
“Well, Merry Christmas to me, I guess.”
“Kacchan! It’s not Christmas.”
“Damn, and here I was going to give you another present.”
Izuku’s face turns red. “Well, I do like presents.”
Katsuki grins.
