Okokok what if?? #krtsk #kurotsuki age gap but uno reverse it where tsukki is in his late thirties, he retired from pro volleyball about 10 years ago, and solely works at the museum now. Kuroo is a fresh faced 22 year old college grad who just signed to his first div 1 team.

Tsukki was a pro volleyball player who started in div 2 but brought the frogs to div 1 before he had to retire for an injury, but he made his peace with it. He was never a household name except for those who played volleyball who hated going up against his disgusting blocks, so

He gets by at the museum and is never really recognized for that part of his life. But Kuroo was a volleyball fanatic who everyone knew had an obsession with the blonde middle blocker, he was part of the reason he chose the position he did. When his new teammate and new bff

Bokuto hears of his obsession, his brain clicks into gear. Bokuto knows the great ninja shoyo, olympic gold medalist, from a training camp he had been to a few years ago and the two of them were friends on social media. He messaged him, remembering that shoyo had been classmates

With tsukki, and wanting to know if he could get like anything autographed for Bo to give to Kuroo for his bday. Shoyo says I’ll do you one better since we’re friends, he works at the sendai museum now, and he tells them what week tsukki was complaining about having to do his

Quarterly coverage of some of the tours, and it’s the same time as Kuroo’s bday. The two of them conspire and when Bo drags Kuroo to sendai on his bday, he’s like what the fuck are we doing here. Why are we at a museum. But Bo looks so excited Kuroo just nods along, hoping to

Let him look around for a bit and then dragging him off to find a bar or something. And then Bo says he paid for a guided tour and Kuroo’s like plotting an escape when the tour guide walks in behind him and calls for the group to huddle up. He begins to think okay well maybe

If the tour guide has such a sexy voice this will be bearable when he turns and freezes because holy shit holy shit that’s Tsukishima Kei retired middle blocker of the sendai frogs and one of Kuroo’s biggest inspiration. He whips his head towards Bo who is just giddy in the

Corner before he whisper shouts happy birthday! And tsukki is like ‘oh is it someone’s birthday? And you chose a trip to the museum?’ And he sounds so good and teasing but also so pleased that kuroo just nods dumbly like he hand picked the event. And as the tour progresses Kuroo

Realizes more and more that he’s fucked because tsukki, while hating being the guide, is incredibly knowledgeable about every inch of the museum and everything he says is so well put together and if the knowledge wasn’t hot enough, the casual confidence in his work was melting

Kuroo’s poor brain(plus the dress clothes? The button up shirt with the rolled up sleeves(cliche kuroo you’re a cliche) showing the muscles that he clearly still works hard to keep???). Bo also keeps doing his whisper shout thing and from the teasing smirks tsukki keeps sending

Them kuroo knows tsukki probably knows that kuroo is fanboying, and how did it take him 23 years to realize he was dumb with no game? He can’t string together a single sentence in front of this man??

When the tour ends, and the other people start to disburse, Bo shoves him and

Kuroo stumbles up to tsukki and is like ‘you’re a really good tour guide. I learned a lot.’ And tsukki is like ‘oh yeah? Ready for the after tour pop quiz?’ And laughs when Kuroo’s face blanks. And Bo shouts ask him for his autograph already and tsukki smirks again and kuroo is

Dying, literally dying.

‘Am I such a good tour guide that you want to remember this moment?’ Tsukki teases.

‘I uh yes.’ Is Kuroo’s reply until bo literally barges in and explains why they’re here and tsukki laughs again and wow is it hot in here for anyone else kuroo thinks.

Tsukki tells them he knows, that shoyo might think he’s slick but he left his phone unlocked and tsukki wanted to know why he was asking his schedule and then furiously typing, so he snooped and saw their messages. And that even if he didn’t see their messages, he still keeps

Up with the sport and would know the two of them anywhere to which kuroo blurts ‘oh god have you seen my games?’ And tsukki chuckles and says yes, that kuroo is a good blocker. Kuroo just goes oh okay I need to sit down and just sits on the floor in the middle of the lobby while

Bo laughs at him, and tsukki smiles but offers a hand to him and asks if they wanted to grab lunch from the cafe before he has to go back to work. (Out of character even for older tsukki, but Kuroo was cute and from the interviews he had seen where he actually spoke, was smart

And witty and tsukki’s exact type.) and they go and get food and kuroo slowly acclimates to being around tsukki and starts acting more like himself, but then just when kuroo was getting into the swing of things tsukki frowns at his watch and starts to say his goodbye, and kuroo

Is like ‘Wait wait can I get your autograph’ cause he can’t bring himself to ask for his number and tsukki’s like what am I signing, your sandwich wrapper and kuroo curses that he doesn’t have anything, and then suddenly tsukki’s grabbing his arm with one hand, twisting it to

Write on it with a sharpie he had in his pocket, winking at kuroo as Kuroo short circuits. He leaves with a wave and kuroo looks at his arm to see tsukki’s phone number and starts yelling, and tells Bo he’s never washing his arm again.

Ps the two start texting pretty

Frequently and pretty heavy on the flirting until tsukki texts him one day ‘are you planning on asking me out this century? 🙄’ and kuroo has to lie down for like 15 minutes before he replies ‘yes like now let’s go out now’

Pps nsfw the first time they have sex is a religious

Experience for kuroo, he wasn’t a virgin but tsukki moved with such certainty and such precise movements, every brush of his fingers whether it was against Kuroo’s overheated skin, or inside of him, had him seeing stars. Tsukki barely bottomed out before kuroo was coming with a

Shout, and then begging for tsukki to keep fucking him as he sobbed from the overstimulation, until he was once again shooting between their bodies as tsukki groaned through his own release.
