My sweet treat for everyone
#出勝 #dkbk | fluff, de-aged Katsuki (4 y/o)

Daifukumochi 「大福餅」🍡

Izuku had an urge—one that he’d been suppressing for Katsuki’s safety. Ever since he saw those puffy rosy cheeks, all he wanted to do was bite it.

And now it dawned on him again, enticing, tempting him to do it.

When Izuku opened his eyes, he wasn’t expecting a ray of sunshine to grace his sight. As though he was but foliage peering through the clouds,

waiting, yearning for the layer of tinted gold added in the sky until everything was in honeyed tones, pleasing, soothing.

And there he was.

Katsuki was small, soft, and snuggling, splayed on top of him like a tiny kitten seeking warmth, his back ever so slightly rising and falling as he breathed softly with his cheek resting on Izuku’s chest.

A bundle of joy free from his insecurities and trauma that used to keep him up at night. Still did.

Seeing Katsuki like this made a wave of nostalgia wash over him. He was brought back to the times when things were simple.

A time when they spend their days playing, running, always chasing after each other, and one of them, mostly Izuku, wouldn’t be far behind.

He was so… 𝘓𝘪𝘵𝘵𝘭𝘦. 𝘐𝘯𝘯𝘰𝘤𝘦𝘯𝘵. 𝘊𝘶𝘵𝘦.

Words he never thought he’d use to describe Katsuki. But then again, Katsuki was endearing in his own way once they saw past his aggressive front.

It took everything in Izuku not to crush the sleeping child in his arms for a hug, wanting to squish him out of cute aggression.

Instead, he settled for the next best thing. Watching Katsuki sleep.

Izuku didn’t expect he would have the opportunity of doing so. Despite the times when they happened to sleep together after staying up at night doing homework, or when either of them went to visit each other’s rooms after a night terror,

Katsuki would always, 𝘢𝘭𝘸𝘢𝘺𝘴, wake up ahead of him. It made Izuku the butt of the joke as Katsuki made fun of his sleeping face, drool still present from the corner of his mouth, snoring the day away.

He always hoped that Katsuki would sleep in one day so he could do the same but right now?

How could he?

Not when he was in the presence of such a tiny, sweet, precious baby Kacchan.

He still couldn’t believe that Katsuki risked Aizawa’s fury just so he could fetch him the umbrella yesterday. But then again, tiny Katsuki was scared. And he always did things once he set his mind to them.

Izuku felt him shuffling on his chest and almost cooed at the sight, careful not to move too much when he reached out to brush Katsuki’s hair back.

Gone were the furrowed forehead, wrinkled eyebrows, and the familiar scowl on his face. All of these were replaced with soft features, a smooth forehead, relaxed eyebrows, and a mouth slightly ajar like a little knot as Katsuki murmured something in his sleep.

Izuku leaned closer to hear it but it only made his heart suddenly clench.

“Mnn… ‘zuku.”

De-aged Katsuki slept without a care in the world, none the wiser to his effect on Izuku as he pressed those soft cheeks against Izuku’s chest, nuzzling further on him.

All that was left was a tiny faint purr and Izuku would completely turn into a puddle… If he wasn’t a puddle by now.

Too much cuteness all at once this early in the morning wasn’t good for his heart.

His chest swelled at the fact that Katsuki was sleeping cozily in his arms, touched by the fact that Katsuki deemed him safe enough to even make him his bed and sleep on top of him, and not just beside him like they used to.

What Izuku wouldn’t give to have a time-related quirk just so he can pause and capture this time for a bit, engrave it in his memory and be in this moment, indulging in the peace and quiet of the mornings he shared with a de-aged Katsuki.

The child stirred on his chest again, exposing one cheek while the other was still on his chest, as though Katsuki was listening to his heartbeat.

Izuku slowly reached out again and this time, he gently poked his exposed cheek.

The sublime plumpness of his cheeks, especially when they puffed out whenever he pouts, never failed to summon a frisson of joy within Izuku.

Oh, how Izuku wanted to bite those cheeks to see for himself if they were just as soft like mochi as he thought. To feel the softness that Katsuki kept and hid within.

🍡🍡🍡

Izuku never thought he’d be tempted again but he shouldn’t have gotten ahead of himself.

The opportunity, read as temptation, arose again when he was studying in the afternoon.

He was in the common room with his classmates for a group study when Katsuki suddenly came running, yelling his name.

“Zu!”

Izuku looked up from his notebook and saw tiny Katsuki wearing a bunny onesie this time and clutching a Deku plush close to his chest.

He thought about how everyone was spoiling Katsuki with gifts and toys now that he wasn’t a ticking bomb of quips and explosions.

But then again, he would be a hypocrite for calling them out.

He was the one that spoiled him rotten as Katsuki ran to him and decided to make Izuku’s lap his throne for today. They stayed like that the whole afternoon with Katsuki munching on his biscuits

as Izuku worked on his math problems.

Looking down, he found himself distracted halfway while writing a formula.

There it was. The source of his distraction. Luring, cajoling, tempting.

Soft squishy cheeks too close for comfort.

Izuku could see those pink chubby cheeks from his peripheral vision. Green eyes were drawn to every movement, every puff of those cheeks as Katsuki happily bounced ever so slightly on his lap while nibbling on his biscuits.

He really wanted, 𝘯𝘦𝘦𝘥𝘦𝘥, to bite those cheeks. For peace of mind. To satisfy his curiosity. To answer whether those cheeks were really just as soft and squishy as they seemed.

Until his dilemma wasn't just a thought in his head anymore.

Izuku had unknowingly leaned down and took a bite for himself, only realizing that he did when he saw how close he was to Katsuki’s face, red eyes widening, staring at his as he felt his cheek gently chomp on the soft, smooth, and pudgy flesh.

It was so squishy, bouncy, and soft like mochi.

He feared that he would make Katsuki cry, or worse, hate him for doing that so he quickly pulled away to make an excuse of biting his cheeks on accident instead of the biscuits.

Izuku tried to apologize but he was cut off when he felt a gentle tug on his shirt.

“Zu…”

Katsuki leaned close to him and tilted his head up. He looked up at him with those tender red eyes, moving his cheek closer to Izuku as if inviting him to bite it again.

“S’okay. Zu needs luck.”

Izuku was reluctant but Katsuki was compelling and still a force to reckon with like always, despite his age. To prove his point, Katsuki pulled him down and even ruffled Izuku’s hair

when Izuku finally relented and rested his chin on Katsuki’s shoulder and bit his cheek again.

Izuku swore he heard Katsuki squeak when he did that. But that was another problem for his heart to deal with.

He could feel his classmates’ deadly stares directed at his back that day but he could care less about it.

Katsuki and his soft squishy chubby mochi-like cheeks were all he needed to focus on.
