What if #krtsk #kurotsuki au ft: A tsukki who is closer to 20 than 30, just moved into a brand new apartment and a kuroo who is closer to 50 than 40, who’s lived in the apartment for a while.

And when tsukki moves in kuroo just hears that a younger man is moving in and part of

Him(he blames it on his moms side of the family) is like how the fuck can he afford this place, it’s not cheap? He must be using his parents money or something. Then the other side of his(this one he credits to his fathers side of the family) is like how can you judge this man

You haven’t met shame on you, so then he goes out of his way to be nice and welcoming. And tsukki is polite but tries to avoid him but they live right next to each other and seem to run on the same schedule so they end up in the elevator together a lot. Kuroo finally breaks him

Down and gets him to agree to come over for a friendly neighborly dinner and he gets to meet tsukki’s snarky side. They become fast friends, tsukki has the apartment from his semi pro volleyball career(kuroo refuses to admit he has been checking out his muscles, but who could

Blame him if he was?) and he needed a place between his museum job and his gym to cut back on travel, and he didn’t like noisy people so he splurged for a pretty expensive place. Kuroo, a scientist because he never met tsukki to make him realize truly how much he loved making

People fall in love with volleyball, is like that’s it you’re coming over for multiple meals a week and if I have extra food im giving it to you and tsukki’s like im not broke? But kuroo wont hear it. They end up having dinner together more often than not, and kuroo finally

Admits to himself that he likes tsukki a lot. But he won’t make a move cause tsukki is young and beautiful and why would he settle for old man kuroo who has more and more grey hairs every time he looks(he thinks, oblivious to the way tsukki looks at him). Tsukki likes kuroo but

Thinks to himself that kuroo clearly doesn’t feel the same way because he’s not reacting to any of the flirty things he does, so he tries to bury his sorrows in other mens sheets. It turns into a like n+1 thing where whenever tsukki has an awful relationship/hook up he tells

Kuroo about it over wine after their dinner. The whole time kuroo is like screaming in his head it’s me I’m here I can solve all of your problems, but he just sympathizes while tsukki mopes that kuroo still isn’t making a move.

Tsukki complains about ushijima who has posters

Of oikawa all over his room and spent more time looking at them during the sex than looking at tsukki. (Kuroo thinks to himself how could anyone have the privilege of seeing tsukki in the nude and be able to look at anything else?? He can’t look away from him and he’s wrapped

In a throw on Kuroo’s couch from the neck down.)

He complains about futakuchi, who when they got to the bedroom told tsukki that if they were gunna fuck he had to prep himself cause he didn’t like doing it, and that he refused to go down on him but expected tsukki to go down

on him. (Kuroo raged at this, how many times had he dreamed about getting to slowly open tsukki up for him, how he had dreamed of worshipping every inch of tsukki’s body with his tongue.)

He complains about suna, who kuroo had thought to himself was going to be the end of

Tsukkis pursuit of happiness, when tsukki told him they were officially dating. Tsukki praised how compatible the two of them were in and out of the bedroom(somehow missing the way kuroo slowly crushed the paper coffee cup he was holding in his hand.) but when things turned

South, when they started fighting more, kuroo was there for him to vent to. When suna broke it off saying the distance was too much for what they had, kuroo was there when tsukki cried on his couch. He was there to brush the tears away and mutter words of comfort even if he was

Sure tsukki wasn’t listening. (He was, he was always listening to kuroo.)

After suna though, tsukki wasn’t mentioning anyone he was seeing and while at first kuroo thought he was just getting over suna, kuroo was starting to doubt it. He brings it up one day, a few months later

Asking tsukki if he had been seeing anyone and when tsukki just tried to shrug him off, he pried. After a few pointed and carefully worded sentences from kuroo tsukki admits that he’s given up on dating, that it’s not for him. He’s sick of wasting time for bad sex or a bad

Relationship, especially when the person he really likes doesn’t seem to feel the same. Tsukki says the last part of the sentence while making direct eye contact which sends kuroo into a flight or fight reaction, and instead of running away like he wants to he kisses tsukki,

Only to immediately pull back and start to apologize before tsukki shuts him up with his mouth. Dinner is forgotten and kuroo takes him apart on the floor of the living room, finally getting to leave his mark on tsukki. In between kisses and bites he tells tsukki how much he

Likes him, how much he cares, and how he’s been driving him crazy this last year. Tsukki just frowns and goes why’d you let me fuck all of those assholes then when we could’ve been doing this the whole time. And kuroo starts to sputter something about how he was old and tsukki

Deserves someone young and tsukki’s like I didn’t ask what I deserved, I want you, even if you can’t keep up with me old man, and flicks a strand of grey streaked hair out of Kuroo’s face. Kuroo shows him exactly how well he /can/ keep up with him and only laughs later when

Tsukki is complaining about rug burn on his knees.

‘Who can’t keep up with who now’ kuroo taunts but tsukki retorts with a

‘I’m not the one who needs more time before they’re ready for round two,’ and when kuroo frowns cause his refractory time is not what it used to be,

Tsukki wipes away the frown with an offer to be the one doing the fucking this time, if kuroo was up for it.

Kuroo obviously agrees but insists they move to the bedroom, sticking his tongue out as tsukki teases his delicate sensitivities for not wanting to be fucked on the

Floor.

After round two they just order in, and cuddle on the bed.

They have their struggles with Kuroo accepting that tsukki loves him despite the age gap, and tsukki accepting that kuroo loves him despite his sometimes less than pleasant attitude(kuroo argues his attitude is

Perfectly lovely) but! They’re in love and they end up consolidating to one apartment after about a year of dating. Tsukki gets kuroo back into playing volleyball for fun(oh how the tables have turned) and kuroo comes to all of tsukki’s games and museum events that he can!
