I don’t know if I’ll finish this in time for #krtsk #kurotsuki day but I wanted to write something short and smutty soo have a krtsk spy au where they work for different companies and they have a rivalry going, they claim to hate each other but let’s be honest they’re down bad.

Tw for blood and murder and a comment about sa / assault (doesn’t happen, just a threat by a throwaway bad guy but proceed with caution)

Tsukishima could not wait until tonight was over. He knew the mission today was going to be long and tiring, he hated infiltrating galas

Purely for the amount of time Akaashi insisted spending to get him all glammed up to blend in with the elites of the art world. Today was especially taxing because the second he walked in, he saw that smug cat from Nekoma, eyes immediately drawn to the figure his suit cut. He

Was loathe to admit that Kuroo looked good, and thankfully the second he opened his mouth to let out his signature cackle, the spell was broken and Tsukishima turned the corner.

The night had been filled with attempting to dodge Kuroo while also follow his target, and

Tsukishima couldn’t wait to curl up in his bed after eating some cheap take-out. His pieces were finally falling into place and Tsukishima shook off the old man who had been attempting to hit on him to sneak behind the scenes. His shoes clicked along the tiled floor, setting a

Steady beat that was only interrupted by the quiet thuds of the men he encountered along the way hitting the floor.

He swore to himself when he caught the flash of bedhead around the way, darting into another corridor and hurrying along it. If this darn cat ruined his mission

Again, he would kill him himself.

He had received the information he needed and was heading to his final stop, one bullet standing between him and his ratty sweats. He was just beginning to think that this night was a solid win, but things went awry as he entered the room the

Target was supposed to be in. He cursed, ducking as a fist swung at his face. He missed serious damage to his face(Akaashi somewhere sent up a silent prayer in thanks, he joked to himself) but the hand collided with the side of his head rather painfully. It knocked his earbud

Out, cutting off all communication with his team and sending a violent ringing though his head.

Their intel had been wrong and he was ambushed by a few of the men’s goons. He swiped his leg out from his spot on the floor, knocking the man who had decked him down, delivering a

Swift bullet to his skull. The next few minutes were a quick flurry of action, and Tsukishima zoned out as he made quick work of the men in the room. He fired his last bullet, mentally cursing as he realized he would have to get his hands dirty to take out the target. After a

Quick assessment of his cuts and scrapes, he stood, straightening his jacket. Before he could open the door, another man walked in. The man was a giant, putting it lightly. He was taller than Tsukishima, a rare feat seeing as Tsukishima was over 6 feet, and built like a bear.

Tsukishima clicked his tongue at the thought of having to take this man down with hand to hand combat. He wanted a vacation after this.

‘Out of bullets? I can’t wait to snap you like a twig,’ the man thundered.

‘I can’t wait for you to try,’ Tsukishima replied, voice cutting

And dry. He raised his fists, assuming a fighting stance. The giant cracked his neck in response.

‘Did you get all dolled up for me? I can’t decide if I want to fuck your broken body before or after I kill you,’ the man taunted.

Tsukishima barely had time to crinkle his nose

Before a spray of blood hit him across the face. The giant fell to his knees, gasping for air but failing as a bullet had torn through his throat. Tsukishima’s eyes widened involuntary, before glancing to the side to see Kuroo strolling in.

‘Moonshine,’ he nodded in greeting,

Placing his gun back in his holster as he looked at Tsukishima.

‘Rooster-san.’ He ignores Kuroo’s affronted noise. ‘I don’t recall asking for your assistance.’

‘This one was free of charge, love. Consider it a payment for how stunning you look tonight.’ His grin was sharp,

Feline like, as his eyes travelled up his body briefly, before he made eye contact with a frowning Tsukishima.

‘Thank you for your services. I’m afraid I’m needed elsewhere.’ He moves to walk towards the exit but is cut off by Kuroo. Kuroo pulls his sleeve down over his hand,

Gesturing to the blood Tsukishima hadn’t wiped off of his face. ‘I don’t need your dry cleaning bill,’ he snarks but makes no move to stop Kuroo as he gets closer.

‘My only regret,’ Kuroo basically purrs as he brushes the worst part of the mess off of Tsukishima’s face. ‘My

Only regret is that I couldn’t take my time killing him, show him what a bad decision it is to threaten you like that in front of me.’

Tsukishima can feel the heat pooling in his gut from the combination of Kuroo’s tone as he gently scrubs Tsukishima’s face. He tries to blink

Back the arousal, he still has a job to do.

‘It’s not the first time some brute thinks he’ll be able to overpower me like that, won’t be the last. I really do need to be going.’

Kuroo steps back at that, assessing Tsukishima with cool eyes.

‘The next time someone says

Something similar, point them my way. And moonshine, can’t we call it a draw?’

‘A draw?’ He raises his eyebrows.

‘Yes, a draw. You got the information I was supposed to protect, so you should at least not kill our client. Neither one of us loses then, love, it’s a win win.’ He

Grins.

‘I seem to recall you calling me an overachiever last month in Prague.’

‘We must remember that differently, love.’ Kuroo’s grin doesn’t falter.

‘Maybe the birds nest on your head is affecting your memory. I don’t compromise, Kuroo-san.’ Tsukishima’s grin is just as

Sharp, and both men take a second to size the other up. They both move at the same time, but Kuroo is just faster than Tsukishima and their brief tussle ends with Kuroo pinning Tsukishima to the ground. His hands pin Tsukishima down, and he leers at him.

‘You should’ve

Compromised, darling moonshine.’ His eyes basically sparkle as he presses his body down, partially to ensure Tsukishima doesn’t wiggle free, partially to feel the planes of Tsukishima’s body against his own.

‘Never,’ Tsukishima smiles sweetly, throwing Kuroo off. He throws him

Off further by leaning in, capturing Kuroo’s lips with his own. Kuroo falters for a second before he reciprocates the kiss, pressing down and opening his mouth at the first hint of Tsukishima’s tongue on his lips. The kiss, while heated and passionate, is brief. Before Kuroo

Realizes what is happening, Tsukishima has flipped them, and has grabbed Kuroo’s gun. He pulls back, grinning as he points the weapon at Kuroo.

‘Like I said, I don’t compromise.’ He backs out of the doorway slowly, eyes never leaving the kneeling Kuroo. Once he knows he’s out

Of sight, he turns and takes off down the hallway. He finds the target and eliminates him, hustling to make it to the pick up spot. Thankfully he doesn’t see Kuroo again, but he tucks his gun in his pants just in case.

After a lecture about losing contact with them, his team

Eventually relents and after Akaashi patches him up, he’s finally heading home. He skips the drive throughs he originally planned to go to, opting for the comfort of his home instead. He showers, and startles when he walks back into his bedroom to see a figure on his bed.

‘Please tell me you showered, I don’t need blood on my sheets.’ He tsks, recognizing the mess of black hair.

‘Ye of little faith, of course I showered darling. C’mere, let me look at you.’ Kuroo reached towards Tsukishima with grabby hands, and in the safety of his room,

Tsukishima complied with no arguments. He let Kuroo fuss over him as he explained that he was fine. Once Kuroo was satisfied, he peeled back Tsukishima’s covers and allowed both of them to curl up together.

‘Kissing me back there was a pretty big risk,’ Kuroo mused as he

Threaded his fingers through Tsukishima’s hair.

‘We were alone. Besides, if anyone asked, I would’ve just told them I was going for your gun. It’s on the nightstand by the way.’

‘Ah good, Bo would’ve killed me if I lost it. Kiss me again, moonshine?’ Tsukishima huffed out a

Quiet laugh, tilting his head up to allow their lips to meet again. Kuroo wasted no time, pressing in insistently, hands trailing up and down Tsukishima’s sides. As their embrace heated up, Tsukishima broke the kiss to gasp for air. Kuroo moved down Tsukishima’s neck, sucking

In marks and biting down, savoring the hisses and whimpers he was getting from Tsukishima.

They had rolled, mimicking the position from earlier with Kuroo pressing Tsukishima into his mattress this time. He pulled back long enough to look into Tsukishima’s eyes, brushing the

Few loose curls out of Tsukishima’s face.

‘You don’t know how livid I was when I heard that man say that to you,’ Kuroo admitted, pressing a slow sweet kiss to Tsukishima’s lips.

‘I tell you every time that you don’t have to worry about me,’ Tsukishima counters. ‘Also stop

Taking the exact opposite of my cases, jerk.’

‘No can do, love. What good is a case if I don’t get to see my lovely fiancée all night?’ Kuroo presses a kiss to the ring finger that while bare earlier, now wears the ring Kuroo had given him months ago. ‘Besides, if you

Would’ve fought that man hand to hand, he would’ve broken your nose and then Bo and Akaashi would have killed me for letting him hurt you.’

‘Yeah, yeah. Shut up and kiss me again.’ Kuroo can’t deny Tsukishima, and they resume the kiss. Neither one of them stops it this time,

when the kisses turn sloppy and rushed, when they both shove at the clothes blocking their skin from contact, as Kuroo continues his marks down Tsukishima’s chest, teeth catching on Tsukishima’s nipples, tongue dipping into his belly button.

‘Hmm, should I skip

Straight to fucking you, or should I take my time worshipping you with my tongue,’ Kuroo asks as he slides said tongue along the divots in Tsukishima’s hips.

‘Fuck me, Tetsu. I stretched myself in the shower, hurry it up.’ Tsukishima pants.

‘His wish is my command.’

Kuroo moves to grab their lube, spreading it on his fingers before they find their way inside of Tsukishima, who wasn’t exaggerating about prepping in the shower. He groans as two of his fingers slide right in, feeling the tacky heat of the lube Tsukishima had already used.

‘You’re too good to me, darling.’

‘Ah, Tetsu. C’mon just fuck me.’ Tsukishima hisses.

‘Shh, let me take care of you.’ Kuroo hushes him but slides in a third finger anyways, twisting them just the way he knows makes Tsukishima see stars. He makes quick work of it, knowing when

Tsukishima demands he hurries it up, he better hurry up, and before long is sliding his length inside of his moaning fiancée.

‘Yes, that’s it. Fuck, Tetsu, you feel so good,’ Tsukishima whimpers as Kuroo starts to snap his hips in and out.

‘You’re mine-‘ Kuroo basically

Growls as he picks up the pace, teeth catching on Tsukishima’s neck. ‘Mine to touch, mine to fuck, mine to love.’

‘Yours, yes, I’m yours,’ Tsukishima agrees, hands coming to thread into Kuroo’s hair, drawing his face up until they’re both staring each other in the eye. ‘Only

Yours, Tetsu. Always yours.’

It’s enough to send Kuroo plummeting, cursing as his release stains Tsukishima’s insides. Once he’s ridden out his own orgasm, he pulls out, scooting down the bed to swallow Tsukishima’s cock whole, bobbing his head a few times until Tsukishima

Is shouting his own release. They collapse together until the drying fluids force them to clean up, and as soon as they’re done with it, they move to the center of the bed, lazily kissing each other until exhaustion starts to set in. As both of their eyes droop, Kuroo yawns.

‘If Bo makes me do paperwork tomorrow cause our client died, I’m making you help me.’

‘I’ll text Akaashi to keep him busy tomorrow, you baby.’

‘Love you moonshine.

‘Love you too, Tetsu.’

End!

It still technically isn’t krtsk day where I live for two more hours but you can all have it all early, as a treat.
