A/N: "If you die, I'm gonna kill you." iwaoi - to be honest I've been wondering what I was gonna make of this prompt but then I suddenly got this random idea today so here's the drabble !

If You Die I'm Gonna Kill You

Pairing: IwaOi

"No! What are you doing?! If you die, I'm gonna kill you. I swear," Oikawa hissed. Iwaizumi looked over his shoulder and glared shortly at his lover who was leaning over him so he could watch what he was doing.

In Iwaizumi's hands was Takeru's Nintendo DS, and he was trying to beat the boss he was stuck at while Oikawa gripped his shoulders from behind.

"You're the one who got into this, not me," Iwaizumi said, letting his fingers brush the buttons and keeping his eyes only half focused on the small screen.

"I can do that! I can beat him for you, leave it to Shittykawa!" Iwaizumi said mockingly, imitating Oikawa's voice in a whiny tone, and the setter indeed whined in response.

"Aaahh come on Iwa-chan! NO! Don't do that, what the hell!" he pointed at the screen when Iwaizumi almost died again.

"If you die it's a game over! We'll lose all our checkpoints and -" Iwaizumi lifted his head and glared at him again.

"Nooohoho don't look away from the screen! I need - I mean you need to beat it for Takeru-kun!" Oikawa yelled, and he grabbed Iwaizumi's head and turned it so it was directed at the Nintendo DS again.

"Noooooo!" Oikawa howled when Iwaizumi received the final blow, and… game over. The setter's jaw dropped and his eyes twitched in frustration.

"Too bad. You're the one who forced it into my hands, I never said I could beat it for you. Try it yourself," Iwaizumi said, dropping the DS onto the table and walking away.

Oikawa followed him, his expression still upset and shocked. Iwaizumi ruined it all. He didn't even try his best.

"I said if you die I'm gonna kill you…" he mumbled in a low and dark voice.

"Hm?" Iwaizumi hummed, standing by the fridge to get some juice.

"I'll kill youuuu!" Oikawa suddenly roared, and he ran towards Iwaizumi and tackled him roughly.

"Ooff!" The juice fell down and the sticky liquid splashed all over the floor. Iwaizumi himself was thrown back against the kitchen counter, and angry hands shot towards his sides and…. tickled.

Iwaizumi gulped and he quickly tried to pry Oikawa's hands off, but the ticklish sensations already shot through his body like electricity.

"N-no don't you dahahahaare! Whyyyy-ahahaha!" Soft giggles slowly got louder and more hysterical, and he squirmed helplessly. The strength in his arms got sucked out with each ticklish shock, and he weakly tried to push his attacker away.

"S-shiiihhittykawahahaha! Stohohop that!" he laughed, but Oikawa was grinning devilishly as his hands kneaded and squeezed his lover's sides.

"Seeing you not giving your best angers me, Iwa-chan," he said, and he ran his fingers up towards his ribs. Iwaizumi squeezed his arms together and yelped.

"Ahaha I dihihid g-give my beheheeest!" he laughed, squirming and struggling against the torturous sensations.

"No you didn't. The it's-just-a-game-attitude was all over you," Oikawa mumbled calmly, and he forced his hands under Iwaizumi's arms and wriggled his fingers into his armpits.

"FUUhuhuck s-staahaap!" Iwaizumi struggled so heavily that he managed to turn around, so he was bending over the kitchen counter with Oikawa behind him. Not a convenient position either.

"Am I right or am I right?" Oikawa said, and now in this new position, he couldn't help but first give Iwaizumi's hips a couple of ticklish squeezes.

"NOHoho! O-of c-course it's hahahaa j-just a gahahame!" Iwaizumi laughed.

"See? Admit you didn't try your best. I know you can be good at anything Iwa-chan, so you need to beat that boss for me," he said, making his boyfriend cackle by scittering his fingers up his sides again.

"Y-you're tahahalking bullshiihihit!" Iwaizumi giggled, and he curled forward and gripped the counter desperately when Oikawa forced his hands in between him and the counter to tickle his stomach.

Gasping for breath and squirming, he collapsed in more hysterical giggles, and his knees buckled.

"GOohohood f-fuck ihihiit s-tahahap!" he laughed breathlessly. He had to use his arms to lean on the counter so he wouldn't collapse, leaving his torso even more unprotected and vulnerable than it was already.

Oikawa smiled contently. He would thank Iwaizumi's body on his knees for being so adorably ticklish. It would give him the upperhand at anything once he got his fingers on him.

"First admit," he said, and he dug his fingers in his sides, poked his fingers in his armpits and scribbled them over his abdomen.

"F-fiihihiine! I didn't dohoho my behehest!" Iwaizumi gasped out, bucking against him and bending his head.

"Now tell me you'll beat it for me," Oikawa said teasingly, leaning in close to his ear.

"Tell me," he said, making Iwaizumi scrunch up his shoulders at the ticklish sensation of his breath against his ear.

"I wihihill hahaha just s-stop alreadehehee!" he begged, and Oikawa finally released him. Breathless and flustered, Iwaizumi moved from between him and the counter, and he bent a little to recover and catch his breath.

"I'll do it, dammit! You. Clean that up," Iwaizumi huffed, and he pointed at the juicy floor before stomping towards the table and grabbing the Nintendo DS.

"Sure!" Oikawa said, back into his cheerful and friendly mode. Iwaizumi sighed and sat back on the couch. Oikawa was right after all. Now that he actually forced himself to take it a bit more seriously, he beat the game in one go.

The next day, Oikawa returned the Nintendo DS to his nephew, boasting about he's the almighty Oikawa who beat it for him!
