The first time that Bakugou Katsuki recalled attending a festival was when he was barely six years old.
It was almost surreal, the first time he saw a poster for the spring events in the heart of Mustafu. Since they were in the heart of the city, everything was within a few minutes’ walking distance. The shops Masaru typically dropped by to pick up groceries from all had the flyers posted near their entrances, and they immediately caught Katsuki’s eye the second he saw them. Crimson eyes squinted up at the pieces of paper curiously while Katsuki’s little hand tightened around his father’s fingers.
Masaru’s attention followed his son’s as they entered the shop. It’d been a while since he’d last gone to a festival. Neither he nor Mitsuki wanted to leave their son with anyone else while they ventured out, and anywhere they went, they made sure they could take Katsuki with them.
Festivals could be loud, though Katsuki’s issue wasn’t really with loud noises since he’d needed hearing aids since he was a toddler. People were the problem, seeing as Katsuki was rather distrusting of people that weren’t his dam or sire. Masaru and Mitsuki didn’t put Katsuki in positions where he could be upset about being forced to deal with strangers.
Yet his eyes were drawn to that poster…
Later on that evening, Masaru brought up the prospect of taking a little field trip to Mitsuki. She arched her blonde brows curiously, glancing between her husband and their pup.
“Is that something you’d want, Katsuki? There’s going to be a lot of people that you don’t know, but papa and mama will be there the entire time.”
Katsuki was holding on to his plastic fork with determination when the question called his attention to his parents. He deliberated on it, stabbing a bit of spicy cabbage with his fork and bringing it to his mouth.
If there were going to be a lot of people he didn’t know, Katsuki was always hesitant. However, he recalled those bursts of color on the flyers all around the shops and remembered how pretty they looked. He wanted to know how they got colors in the night sky like that…
“Go,” Katsuki murmured while crunching on his cabbage. Masaru and Mitsuki regarded him with pride and surprise respectively before nodding to one another. They’d make this the best outing of Katsuki’s short life, complete with yukata sets and all the food he can eat.
The preparations were under way. All Katsuki knew for the coming weeks was that they had plans to go to this thing called a “festival”. Under the surface, Mitsuki was searching for fabrics and sending pictures of samples while Masaru was secretly taking measurements and looking for forms to make all of their yukatas by hand. To them, it was a simple gesture that was meant to make the first festival the most memorable one.
They took their time, ensuring that every fold was right with not a stitch out of place. When Masaru was too tired to work on them, Mitsuki took over and added bits of progress to keep the projects going while he rested. They distracted Katsuki by playing with him, reading to him at night, or asking him to help them make dinner after studying with him. Still, Katsuki had no idea until the day of the festival came. He’d heard the other children at school talking about it and recalled that yeah, he did ask his parents if they could go to that, didn’t he? Katsuki walked home from school that day with thoughts full of funny stalls and lanterns hung from the stars. He didn’t know how they got those lights up there just yet, but he was going to figure it out by seeing it for himself.
Masaru was home, awaiting his pup with a huge smile and dark circles beneath his eyes. Thankfully, he and Mitsuki had divided up the work pretty evenly, so he didn’t exactly feel pressed for time. Instead, he’d worked on adding little embroidered details the entire day, outlining purple and red flowers in black thread to help them stand out against the cream backdrop of Katsuki’s yukata. He did the same with the cranes and fish on Mitsuki’s yukata and left his own plain, mostly wanting the two of them to stand out.
“Did you have fun at school?” Masaru asked as Katsuki reached up to take his hand. That little head of spiky hair bobbed up and down as Katsuki started to speak.
“Learned about math,” Katsuki went on, and Masaru hummed in intrigue. Katsuki always caught on to material so quickly in school that he and Mitsuki felt like they were just there to make sure he turned in his homework the next day.
“Math’s fun. Your sire’s real good at math, y’know. She was the top of her class.”
It was amazing to someone as little as Katsuki that there was a time when his parents went to school. Did they go to the same school that Katsuki did? What were their classes like? Were the subjects Katsuki liked the same ones they liked?
“Wha’s dam’s fav’rite?” Katsuki asked, turning his gaze up to Masaru. Surprised, brown eyes turned to Katsuki, almost as though he didn’t expect his pup to ask anything like that about him.
“Hm. I think mine was science. It’s got a lot to do with math, and you’ll probably be learning about it soon.”
Katsuki’s response was a tilt of his head as Masaru led him into his parents’ room. Typically, Katsuki studied in the living room at the squat table between the couch and television with at least one of his parents by his side. They seemed to be bypassing all of that today, since Katsuki’s backpack was left in the living room without any indication of being needed.
He was going to ask if they were doing something else when Masaru asked him to wait for a moment. Katsuki was guided to sit in his parents’ shared nest-den while his dam made his way over to the closet.
“Your mother and I have been working on something in secret, but since we’re going to be going out tonight, I figure I should go ahead and show you what it is.”
In Masaru’s hands was a little, embroidered yukata with dark flowers and bright fabric. It looked like it was just Katsuki’s size, making those vermillion eyes widen into saucers. What was this? He’d never worn something like this before, but it looked soft and comfortable for how warm it was outside. Katsuki reached out to Masaru with his hands open and fingers splayed, wanting to feel it. Texture, like his signing, was a big part of his learning during his childhood, making anything that was a good texture easy for him to come to love. Masaru brought it closer, into his pup’s hands, and his eyes lit up when Katsuki made a soft, rumbling noise when his fingers passed back and forth over the yukata.
Katsuki! Was purring! Masaru wanted to call Mitsuki and tell her, at least get her to hurry home a little sooner, when they both heard the front door open and a familiar voice announce itself.
“M’home!” Mitsuki’s voice carried through the house, making Masaru’s chest warm and his own purring start up like an engine compared to Katsuki’s softer sounds. Mitsuki could always use her mate’s purring as a form of finding out where he was. The most adorable part was how Kasuki had joined him with his own pleased sounds. Mitsuki stopped in the doorway, watching both of them as they turned to her. Katsuki was brushing his fingers back and forth over his gifted yukata like it was a new blanket, and Masaru wasn’t even trying to help him put it on.
Well, it could have been worse. These were her boys, and maybe they just needed some guidance every now and then.
“C’mon,” Mitsuki urged, grinning big just like Masaru was. “You gotta try it on before we can go.”
That night was etched into the back of Katsuki’s eyelids for years to come. He remembered the colors and sounds, even all of the people that they saw, and wanted to experience it over and over. Wide, crimson eyes glanced about in wonder every time Katsuki heard a new sound, and by the time for fireworks rolled around, he was staring expectantly at the sky as though they would magically appear when he told them to.
Having anticipated his excitement and the need to stand somewhere close to the action, his parents told him if he wanted to remove his hearing aids at any time, he could. Katsuki couldn’t have understood what they meant by that until the first red-hot firework launched its way to the sky.
Katsuki snapped his attention to the whistle, brows knitting as though whatever this sound was, it was cutting into his firework time. He never could have expected that the whistling would end in a loud boom! and a burst of color that lit up the night sky. Reds, pinks, and bright white painted the nighttime sky, reflecting in Katsuki’s eyes as he gazed up at them. The fireworks fizzled and sparked in the shape of a mischievous kitsune, a shape that he easily recognized from the tails and fox-like body. If he’d thought to speak, he’d be ooohing in excitement. But the entire time, he was absolutely silent. Katsuki was enraptured by the sight and clinging onto his dam’s yukata with tiny fists.
The fireworks lasted for a little over half an hour. The end was announced by an announcement on a loudspeaker thanking them for attending the festival and informing them of the next festival within the area. Katsuki blinked when the end drew near, looking about in confusion when other families and couples were starting to move towards the exit and the stalls closed.
“Is over?” he asked quietly, eyes on Masaru and Mitsuki. Their hearts ached at how sad he sounded at the loss, but they were quick to reassure him.
“It’s over for now, yeah. But there’s going to be lots of other festivals. Would you like to go to another one in a couple of months?” Mitsuki offered. Masaru nodded in agreement, knowing it’d be good for them to get Katsuki comfortable around more people as he got older. If he liked festivals, they’d take him to as many as they reasonably could.
Katsuki gazed between the two of them with wide, hopeful eyes. It wasn’t like their pup to ask for much with how self-sufficient he tried to be. Katsuki was intelligent, and while his parents wanted to nurture his independence, they also wanted him to be a pup for as long as reasonably possible. They loved him and wanted Katsuki to experience a childhood that he could look back on fondly.
“Wanna go,” their pup agreed. He was holding the collar of Masaru’s yukata in tiny fists like he couldn’t believe he’d get to see it again. The fireworks had been so loud, but they were also pretty and bright. He could see them behind his eyelids whenever he closed them, even after they’d all bathed and gotten into the nest-den.
That night, Katsuki asked to sleep between his parents like he had only a few years ago. He nestled between them and slept so soundly, holding on to both of his parents’ fingers as though he were afraid they’d let go. Masaru and Mitsuki kissed both of his tiny cheeks and then one another. They were going to do everything in their power to make this a regular experience for Katsuki, regardless of how much time and effort they’d have to put in to make it so.
That was the start of the tradition. Every couple of months, Katsuki would attend a festival with his parents, and he’d get to relive that amazement all over again. Even when he was too big to be held like a small child, Katsuki would stand between them and hold on to their hands. It wasn’t even a decade after the first festival when his parents noticed signs of Katsuki starting to present. His scent was growing much more spicy, and his moods were harder to predict. On top of general puberty, Katsuki was likely going to present as an omega.
To Masaru and Mitsuki, this was a proud moment. They couldn’t have been happier that their sweet boy was growing into his body and becoming an adult. The idea of a mate was on the horizon, but they fully intended on doing as their parents had with them and letting Katsuki find his own mate. He was levelheaded when needed and didn’t put up with being treated unfairly, and he’d always have their guidance if he ever needed it. They simply wanted the absolute best for their son, meaning they’d do absolutely anything to give it to him.
So, when Katsuki was 13 and finally started to shift things about in the nest-den, his parents glanced at one another knowingly. All secondary genders got restless when they started to present, but omegas and alphas had the need to rearrange everything in sight to appease their instincts. It was both a test for themselves and their son, watching their feverish pup moving about the giant pile of blankets, pillows, and clothing. He shifted items about, huffing in between long, purred breaths, before finally taking to plopping down on his back in the middle of the giant sleeping crater.
Those crimson eyes were mostly pitch, swallowed by blown-wide irises as Katsuki found his dam’s gaze to ask a silent question. Masaru seemed both surprised and worried, looking to Mitsuki for support. It was unfair how alike her and their pup were, the spitting image of one another.
“Go on,” Mitsuki urged. “He’s asking for you, so you better not keep him waiting.”
Masaru took a step closer, and before he knew it, Katsuki was wriggling from his clothes to lay bare before them. He was so trusting in how he kicked his pajamas into the nest so it’d smell even more like his emerging spun sugar and heavy, spiced scent. His eyes flicked to Masaru’s clothing, like he expected the same thing, and the older omega earned a louder purr the second he went to unbutton the collar of his shirt.
With their clothes tucked away in the nest and Katsuki making happy, grabbing motions for his dam, Masaru kneeled in the nest and settled in between Katsuki’s legs and their chests pressed together. The younger omega purred away as he nuzzled and scented his dam, letting out happy, happy omega! pheromones the whole time. Skin-to-skin, Masaru could feel the heat rolling off of Katsuki’s body in waves. He caressed Katsuki’s sides with his hands and purred and scented his pup in return, letting his more subtle yet still sweet pheromones cling to his son’s skin.
It wasn’t long after that Katsuki was tilting his hips up and brushing his core against Masaru’s stomach. There was no surprise from his dam, nor was there any inclination for Katsuki to stop. Masaru encouraged him with a hand instead, using two fingers to grind against his pup’s swollen, twitching clit. The second Katsuki purposefully rutted into his dam’s hand, he was rewarded with a light kiss that had him chasing after Masaru’s lips for another, and then several more.
“That’s it, sweetheart, you’re doin’ so good,” his dam encouraged. Katsuki’s first orgasm was explosive, quite literally, both with his quirk setting off the tiniest pops in his hands and his hips stuttering and bucking against his dam’s fingers. Masaru cooed soft words down to Katsuki, nuzzling and holding him until his pup was moving again. Two, three more shuddering orgasms followed the first, and Katsuki’s hips were growing tired.
Masaru eased down between his pup’s legs, earning a loud whine that melted into a surprised, shuddering moan when his tongue found Katsuki’s cunt. He lapped one stripe, then another before he was exploring his sweet boy’s cunt. It was easy to pull another orgasm from him with Masaru’s expert tongue, and it didn’t stop when Katsuki whimpered about having to go. Masaru latched onto his pup, tongue roving when Katsuki couldn’t hold it in anymore. He didn’t know it, but Masaru’s purrs were the loudest when he was making sure his pup didn’t make a mess in the nest-den.
Mitsuki had gotten snacks and came back to settle on one of the walls of the nest. She petted her boys’ heads, earning happy rumbles from both of them. Masaru tugged at her hand as he went to settle with a tired Katsuki against his chest. She kissed Katsuki’s cheek, then Masaru’s lips before humming softly at the taste.
Katsuki slept clinging to Masaru with Mitsuki at his back. He’d wake up, blinking blearily and asking for another round of cuddles and kisses before Mitsuki took her turn to explore their pup. They were gentle, pulling soft, pleasured noises from his lips before he slept again. In between it all, they’d glance at one another, steal kisses from both their pup and one another, simply happy that Katsuki trusted them enough to let them help through his first heat.
In the end, Masaru was propped up on an elbow, listening to the fireworks on the television from the nearby festival and watching Katsuki nap. He glanced over at Mitsuki, then back at their pup, feeling his heart more full than it had been before. He was thankful, but kept quiet as though to preserve the moment.
Nothing, in his eyes, could have been better than this.
