ok but nsfw #dkbk light petplay where Izuku's just trying to get some work done at home.
It's just menial paperwork, not worth a trip into the office.

Katsuki makes it impossible.
His Kacchan excels in many things—prompt completion of red tape required things included.

But Izuku's not a fucking psychopath, showing the proper amount of disdain for such a chore.

It's bad enough on its own, the last thing Izuku needs is Kacchan prancing around the house in lingerie or ridiculing him about taking so long to complete his work.

After being rudely interrupted while trying to work on the couch—the most comfortable place for him to work, considering the conditions of his joints—by a naked Kacchan sprawling out beside him, lighting trailing his fingers up and down his own body.

He breaks out a well-loved bullet vibe, and Izuku forces himself to ignore Katsuki's exaggerated moans.

But Katsuki's no quitter. He ups the settings to the vibe and nearly kicks Izuku's computer out of his lp and into the floor when it feels too good.

Izuku half-heartedly admonished him, just wanting to get his work done so he could enjoy time with his husband, and moved to the study.

As soon as he got set up in there, Katsuki appears in the doorway and says, "Really, Deku? You didn't finish it yesterday, so you're using /our time/ today?"

"It'll only take, like, thirty more minutes! It was a big incident, Kacchan. If you'd let me work in peace, I'd be done by now!"

"It's not /my/ fault that you didn't do it yesterday, nor is it my fault that your horny ass can't focus with me around. /I'm/ just trying to 👇

enjoy my day off work."

"Kacchan—"

"/You're/ the dumb Deku that didn't do it already!"

"/Enough/, Katsuki."

It's been awhile since Katsuki's tried this to get a rise out of him.

"We're going to the bedroom. Get the vibe." Izuku's tone is stern and his face indifferent.

Katsuki smirks, like he just won a game.

Izuku can't wait to wipe it off his face. He brings his laptop with him to their room, situating himself in the armchair across the room from the bed.

Katsuki saunters into their bedroom, frustration souring his face upon seeing Izuku.

"You're going to get on the bed, put in the bullet, and turn it to half power," Izuku says from his seat in the corner, thankful his laptop hides his hard-on.

"But—" Katsuki whines.

"But /nothing/. You've been a brat all day and I've had enough of the attitude." Izuku's voice is low, but still calm and a little rough. "/Now/, Katsuki."

The blond sighs, pout on his face as he climbs onto their bed.

"I, um, still have the vibe in," Katsuki admits, pink coloring his cheeks.

Kacchan's so cute when he blushes.

"Slut," Izuku says affectionately. Katsuki meets his eyes and the blush spreads to his chest. "Once the vibe is on, you're going to hold onto the headboard 👇

and wait for me to finish my work. You're going to be quiet and you're going to be /still/."

"Sir, I—"

"What's your color?"

"Green—"

"It's not up for negotiation, puppy. Do you want me to get the muzzle?"

Katsuki shivers, precum leaking from his cock, but shakes his head no.

He keeps eye contact with Izuku as he easily switches the vibe on and up to half power.

He jolts when it starts up, pleasure racking his body.

"You can come as many times as you'd like, just keep your hands on the headboard. 👇

I will not touch you until I'm done with my work. And unless you're giving me a color, my pretty puppy's going to be quiet, right?"

Katsuki nods, skin thoroughly flushed.

"Good boy," Izuku praises before directing all of his attention to the screen in front of him.

He glances up often, admiring the sweat beading on Kacchan's chest and how his muscles flex as he grips the headboard.

Katsuki cums with a moan and with his body impossibly tensed.

Izuku may or may not have taken a bit longer than usual on the paperwork, 👇

but that's not his problem.

And if Izuku's technically done with paperwork and just waiting to hit submit, that's no one's business but his.

He enjoys watching Katsuki squirm and bite back his whimpers.

When Katsuki cums a second time, louder than before, with a 👇

pitiful moan and his eyes clenched shut, Izuku decides to show him a little mercy.

...once he's about to cum a third time.

Izuku dutifully ignores the oh-so-enticing sounds slipping from Katsuki's lips, and hits submit on his paperwork.

Katsuki's so sensitive, he'll be on the edge in mere moments. Quietly closing his laptop and setting it to the side, Izuku pads over to the bed.

He loves the noises Katsuki tries so hard to hold back, and when they start picking up again and his body tenses and relaxes, 👇

hips moving in an effort to get more stimulation that won't come, Izuku knows his puppy is close.

He reaches down and turns off the vibrator entirely with deft fingers.

"N-no, 'Zuzu," Katsuki whines. "I was so close."

"I know, puppy." Izuku runs his fingers across 👇

Katsuki's scalp, pushing the sweat-damp hair from his face. "But that's enough for now. You can let go of the headboard, baby."

Katsuki drops his arms, then reaches for Izuku. Raising Katsuki's knuckles to his lips, he presses a light kiss to the skin.

"I'm sorry, Izu..."

Izuku gives his hand a light squeeze. "It's okay, puppy. Once we came in here, I started to enjoy paperwork a little bit."

Katsuki rolls his eyes.

"Want to watch a movie?"

Katsuki nods, rolling to the side of the bed and sitting up.

"Can I get cleaned up first?"

Izuku's sure the dried cum on his chest is uncomfortable. "No. I figured you'd add to it while you cockwarm me."

Katsuki's ears are practically burning.

Izuku watches with a raised eyebrow as Katsuki stands and walks towards the door.

Izuku clears his throat.

Katsuki looks back at him. "Really, /sir/?"

/Really./ Izuku crosses his arms across his chest, face stern.

Once Katsuki drops to his knees and begins crawling towards the living room, he grins.

Kacchan is the best puppy, and he's all Izuku's.
