Work Text:
Being a married couple for years now, of course they have silly nicknames for each other. Katsuki, in particular, is the undisputed master of that art.
He’s called his husband all sorts of names—some cute, romantic, and intimate, but also downright weird. Candy Cane, Icy Hot, Canada, Mochi Cheeks (for his round cheeks when he’s munching)—the list goes on.
For Shoto to come up with weird names for Katsuki is pretty rare, which only makes it more surprising when it starts happening more and more all of a sudden.
One evening, Katsuki was in the kitchen, cooking dinner when he heard Shoto calling from the laundry room.
"Katsuki, can you bring me another basket, please?"
He muttered a distracted, "One sec," not expecting much. But Shoto calls again, louder this time.
"Handsome, my Cutie Patootie, my Mister Maaan—uh, a basket, please."
What—
His hands stop mid chopping motion, he blinks once.
A snort escapes him, and suddenly, he throws his head back and bursts out laughing at the absurdity of those names. In Shoto’s monotone voice as well.
"Shou, what the fuck?" Still chuckling, he shakes his head.
From the other room, Katsuki can hear the smile in Shoto’s voice.
"Well, if you don’t react when I call you by your name, I’ll have to get creative."
And that was just the beginning of it all.
~~~
"I’ll get some stuff for dinner. Do you need anything, my Pooh Bear?"
Years of marriage have sharpened Katsuki’s eye for noticing how much effort Shoto puts into controlling his face—trying not to cringe or smile at that ridiculous nickname himself.
But Katsuki isn’t about to give him the reaction he’s hoping for.
"No, my little Cream-Filled Doughnut. I’ve got everything I need right here—probably more than that even."
His eye twitches with those words. Damn, he slipped.
Shoto smirks, satisfied, and turns away.
~~~
"Saw your fight on TV, He-Man. You did great." His tone is deadpan, his face remains serious.
Katsuki flips him off and makes him wait—two whole minutes longer—before he finally comes over for a welcome home kiss at the doorway.
Hah. Suck that, Shoto.
~~~
"Can I have a taste from the curry, Honeybutt? Just a little, please?"
Katsuki turns in the hold Shoto has on him from behind, pinning him gently against the counter.
He flicks his husband’s forehead with a playful scowl.
"Ouch, rude," Shoto pouts, rubbing the sore spot like a kicked puppy.
"Now you can," Katsuki replies sweetly, grabbing an extra spoonful of curry from the pot and letting Shoto have it.
He leans forward for a quick forehead kiss as an apology after. Shoto smirks, triumphant once again.
~~~
The last time it happened, Katsuki's honestly saintlike patience snapped finally.
"Hey, Shou. Tomorrow’s our day off. Want to watch that show you talked about after dinner?"
He’s sitting on the couch, flipping through channels. Shoto, nose buried in a book in his reading corner, doesn’t even look up at the question, too distracted by the story it seems.
"Sounds good," he mumbles.
Katsuki leans back over the back of the couch, now watching his husband upside down, grinning.
"I’ll run to the store for drinks if you make some popcorn. Deal?"
Shoto turns a page. "For you, of course, my Love Nugget."
Katsuki sees him bury his face deeper in the book, obviously trying to hide his grin.
That’s it. Enough is enough. That man’s done.
He switches off the TV, grabs his mug, and heads to the kitchen sink. When he returns, his expression is dangerously calm.
He approaches Shoto’s chair, gently takes the book from his hands, carefully places it aside with the bookmark between the pages, and leans down, effectively trapping Shoto with his arms on both sides.
"Now… what do I do with you, huh?"
Shoto looks up, a playful smile on his face, like the little shit he is.
"I don’t know. What do you have in mind?"
"Oh, I can show you, princess," Katsuki smirks, eyes darkening. "You’ve got some learning to do. You up for that?"
"Mmh, you gonna teach me a lesson now, Kats? I’m learning pretty fast, y’know. You’ll have to take your time, or I’ll pick everything up too quickly, though, I fear,” he pouts, pupils blacking out his mesmerizing eyes almost entirely with every word he mutters.
Katsuki cups Shoto’s chin, squeezing his cheeks together between his fingers since Shoto just patiently sits, letting him do as he pleases. His words are a soft contrast to the action.
"That’s because you’re so smart." Katsuki praises, meaning it, even though it might sound teasing in the moment.
And then, without warning, he pulls him up and throws Shoto over his shoulder. A startled noise escapes his husband, and Katsuki takes in his soft giggles with a warm smile. When he playfully taps his ass, he earns himself a slap in return.
When they hit the bed, Shoto is still smiling—probably contagious, because Katsuki finds himself grinning down at him as well.
He pulls Shoto roughly by the thighs until he’s hanging at the edge of the mattress. Oh, this is going to be fun.
~~~
"Please, Katsuki, fucking please! More! Please, I said it!"
Shoto is a sobbing mess beneath him, face buried in pillows, Katsuki’s hand firm on the back of his neck and the other pushing on his lower back. Hips lift in his grip, trying to take in more of Katsuki’s cock, but Katsuki keeps him on the edge—only the tip.
Shoto tries pushing back repeatedly, but Katsuki pulls out each time he gets too close, leaving him crying and begging each time.
"Again."
"Katsuki!"
"Good. Again."
"KATSUKI!"
"You’re doing so good, princess."
Shoto moans at the praise—then sobs after another failed attempt at fucking himself on his husband’s cock. He whines when Katsuki pulls out once again.
"Did you learn something today, Shou?"
Katsuki remains calm, pleasuring himself as he rubs between Shoto’s cheeks or lets the tip slip in occasionally. He’s enjoying this, and clearly, so is Shoto.
"I did, pl-please, Katsuki, please lemme—,” he sobs, taking in a shaky breath, “—have more. I’m good, really good, p-promise—"
He’s rambling now, tears streaking his face, drool dampening his cheeks and the sheets below.
"You’re a good boy, right? Just like to tease me sometimes, huh?"
Katsuki can’t help but adore this man beneath him—so beautiful, so precious. He is reaching a breaking point as well now, unable to resist his gorgeous husband any further.
"Mhhmm," Shoto nods desperately, voice trails off as he struggles to talk through the torturous pleasure.
"Okay, baby, take it then."
This is a warning—if he feels overwhelmed, he can say no. But Shoto, ever eager, pushes himself down again immediately, trying to take Katsuki deeper.
He buries himself in one thrust, and Shoto screams. Beautiful.
Katsuki releases his grip to instead hold onto Shoto’s arm and pulls his hips against his own with almost punishing force.
He fucks him fast, hard—no holding back.
Shoto’s legs give out soon, and Katsuki lets his weight follow until he is completely blanketing him.
"What did you learn, Shou?" Katsuki manages to say, voice rough right beside his love’s ear.
"Katsuki—"
He smirks. That's right.
"One more time, please."
Shoto presses his lips to Katsuki’s clumsy, moaning softly.
"Katsuki."
~~~
In the end, Katsuki isn’t entirely sure if this was the smartest move on his end. Because now, that little fucker Shoto will keep saying his name seductively—trying to make Katsuki pop boners in the worst moments possible. Yeah, he might have pavloved himself here.
Maybe it’s time for the next lesson then.
After all, Shoto learns fast.
