Miya Atsumu doesn't particularly mind living in the team dorms. Well, technically it was "athlete subsidized housing" provided as part of his contract with the team, but everybody just calls them dorms because that's what they are, considering you only got allotted one private bedroom in an apartment where you have to share a bathroom and kitchen with at least two other guys.
Most of the time it really isn't too bad. Atsumu had grown up sharing almost everything with Osamu, which is just par for the course when you're twins and everybody treats you like a combined unit. In fact, his current situation is certainly a step up from high school, where he'd had to share a cramped dorm room with his brother all three years at Inarizaki. At least he doesn't have to try and sleep through Osamu's thunderous snores anymore.
Sure, sometimes he squabbled with his teammates over whose dirty dishes those were in the sink, or whose turn it was to take out the trash, and Bokuto loves taking an ungodly amount of time in the shower for some fucking reason—but living in the dorms is better than not living in the dorms. See, that's another thing about growing up with a twin. Atsumu had never had to be by himself before, and he'd never admit it out loud but he thinks he would go crazy if he came home and was greeted with nothing but silence, silence, and more silence.
Plus, rent is cheaper in the athlete subsidized housing considering he is, you know. An athlete.
Living with somebody other than his brother had been different, at first. When Atsumu had first signed with the Black Jackals, he'd spent three seasons rooming with Inunaki, who was several years older and therefore much more put-together than 18-year-old fresh-out-of-high-school Atsumu, and Adriah, who didn't speak a lick of Japanese. The roommate situation then had been a lot more professional, mostly owing to the fact that Atsumu didn't share too much in common with Inunaki off the court and he had no clue how to have a conversation with Adriah.
Then, he had walked into the locker room on the first day of practice in his fourth season as a professional volleyball player and saw Bokuto Koutarou standing there in a team jacket that was identical to the one Atsumu had on.
The rest, as they say, is history.
In other words, ever since the day Atsumu and Bokuto became teammates, therefore making Bokuto similarly eligible for the athlete-subsidized housing, Atsumu has not known a day of peace. Years pass, seasons change, and so do teammates, but Bokuto's penchant for chaos is always reliably a constant.
Over the years, Inunaki has moved out, Bokuto had moved in, Sakusa had briefly moved in and then immediately back out when he realized he wasn't poor or desperate enough to keep living in the dorms with three men who "have never used a disinfectant a day in their lives." Hinata had moved in, and that was fun for a while, and then he'd packed up all his sunscreen and flew back to Brazil.
The dorm had gone from quiet to lively to slightly less lively to quiet-but-lively again, and the rent was stabilized and Atsumu (mostly) likes living with Bokuto (who keeps things interesting) and Adriah (now Japanese-speaking). Therefore, he hasn't really seriously considered moving out and getting his own place like Sakusa even though he most certainly could afford it now.
This changes on an unassuming Friday one day in late November.
The Black Jackals had played the Azuma Pharmacy Green Rockets earlier that day and narrowly lost. The team is planning on heading out for a post-game meal, but Atsumu wants to review the game footage and this is the first time he's seen Osamu in almost a month, so he bows out from the team dinner in favour of mooching off Osamu's unsold stock. After scoring a free meal from his disgruntled brother, he goes back to the dorm to find his roommates still gone and quickly takes advantage of the free bathroom to shower and wash up. Settling into bed, he loads up the match replay from earlier, and starts analyzing their plays.
He's in the middle of replaying the moment Kiryuu got around their triple block near the end of the third set when a particularly loud bang! startles him badly enough that he pauses the video to listen for the source of the noise. Logically, the sound means his roommates are back, but neither Adriah nor Bokuto typically make that much noise and there's a suspicious lack of either of their voices, so Atsumu is curious.
The walls of their dorm are relatively thin, and Bokuto's room shares a wall with Atsumu's, so usually Atsumu hears him when he goes to his room. However, it sounds like whoever just made that commotion hasn't made their way down the hall yet and it's been a few minutes, which is getting suspicious.
Just as Atsumu is debating on getting up to check out what's going on, he hears some shuffling from the hall and then several loud thumps. Now mildly concerned, Atsumu's about to get out of bed when all of a sudden he hears two voices.
They're not close enough for Atsumu to understand what they're saying, but it's loud enough for him to recognize Bokuto's resounding voice. The other one is less distinct, a lower lilting tone that definitely doesn't belong to Adriah.
It's when a burst of giggles puncture through the walls that Atsumu connects the dots. That's Akaashi.
Atsumu vaguely remembers Bokuto rambling in the locker room before the game about his long-term, long-distance, high-commitment, serious boyfriend. Keiji's coming today! he'd shouted. I can't wait to see him, I've missed him soooo much! Hey, Tsum-Tsum, can you set me a bunch today so I can look extra cool? It's Keiji's birthday next week so we're gonna celebrate after! Come on, let's go win this thing!
They hadn't won the thing, but considering Akaashi's birthday wasn't changing anytime soon, Atsumu figures they must have celebrated anyway. Now that he thinks about it, he thinks he can recall Bokuto also turning down the team in favour of leaving with his boyfriend.
As the voices and giggling get louder the closer they get to Bokuto's room (and by proxy, Atsumu's room), Atsumu very quickly concludes something else: Bokuto and Akaashi are definitely wasted.
It's evident in the way they're making absolutely no effort whatsoever to be quiet, Bokuto's already loud voice even louder and Akaashi breathy and giggling in a way Atsumu has never heard him sober. Akaashi's always deadly impassive whenever Atsumu sees him, which is actually kind of weird now that he thinks about it considering Atsumu's seen him emote with plenty of other people before. Huh. Does Akaashi not like him or something?
The one time Atsumu has seen Akaashi anything other than composed in front of him is at this one V.League charity gala, where Akaashi had gone as Bokuto's plus-one and gotten unexpectedly tipsy. He'd spent the entire night plastered to Bokuto's side and smiling dopily every time Bokuto opened his mouth, which had utterly baffled Atsumu at the time. Nothing Bokuto was saying really ever warranted that kind of reaction.
Although, Atsumu is quickly realizing that's probably just what alcohol does to Akaashi. Some people are sleepy drunks, some are sad drunks, and Akaashi apparently is a giggly drunk. Go figure.
Another loud slam, this time coming from next to Atsumu's room. They've made it into Bokuto's room, then.
Atsumu sighs. Well, good for them. He can't even be upset that Bokuto is drinking in the middle of the season. They don't have any games for the next week and the man rarely drinks anyway. Atsumu supposes it's a special occasion or whatever.
He resumes watching the match, quickly forgetting about the couple as he refocuses on the game. He manages to make it a whole seven minutes before being distracted by a sound coming from Bokuto's side of the wall.
Instinctively, Atsumu knows what that sound is. However, because he prefers not thinking too deeply about the private lives of his teammates, he makes the executive decision to actively suppress that knowledge. He decides to tune out any noise he may or may not hear from Bokuto's room for his own peace of mind, which is a skill he luckily developed from years of tuning out things like his brother's annoying bitching and his brother's annoying snoring.
This strategy works until it doesn't, because the next thing Atsumu knows the match playing on his phone is already well into the fourth set and Atsumu has no idea how it got there. Instead, he now has a very good idea of what Akaashi Keiji sounds like getting fingered by his boyfriend.
"Please, please, please fuck me, please, oh—"
Akaashi's voice is high and needy, which is in direct contrast to Bokuto's rumbling, "I will, be patient, baby," that can be just barely made out through the wall.
"Hnngh, ah, I need you to fuck me, I've been thinking about you—hah—all day, I want you in me please."
Jesus Christ. Atsumu never, ever could've guessed that Akaashi could talk like this. Not that he'd thought about Akaashi in this context before tonight, but damn. He was usually so serious and proper.
Vaguely, he could hear Bokuto respond with, "Oh yeah? Been thinking about this all day, have you?"
"Yes, yes, you were amazing today, god, couldn't take my eyes off you, hmm—ah—oh, please you need to get your cock in me now or I'm gonna come—"
Atsumu feels his own dick twitch in his boxers. Shit, he's getting hard. Phone completely forgotten with the game still playing, Atsumu holds his breath as the noises in the other room quiet down for a moment before a loud moan sounds out again, this time accompanied by a low groan from Bokuto.
Less than ten seconds later, a thunk shakes the wall, and then begins repeating in a steady rhythm that's no doubt the sound of the bed frame hitting the wall.
Atsumu palms himself through his sweats as he listens to Bokuto fuck his boyfriend in the next room, Akaashi's high moans echoing through the walls. They probably don't know that they're not alone in this apartment right now and Atsumu's eavesdropping on them like a pervert. Or they're too drunk to care. Is what he's doing eavesdropping though? He'd been here first and it's not his fault the walls are thin and he can hear practically everything considering they're not being very quiet and literally doing it right next to his room. God, he's so hard right now.
It's been a while since Atsumu got laid, which is what he's going to blame what he's about to do on. For a second, he pauses and debates whether it's weird to get off to your teammate and his boyfriend having sex and whether this will make things awkward the next time he sees them. Only for a second though, as his brain isn't capable of processing complex thoughts at the moment since all the blood that usually supplies oxygen to it is currently busy making his dick hard. So instead of thinking about it any more, he reaches over and pumps a little lotion from the bottle on his nightstand and pulls his cock out from where it's leaking in his boxers.
Atsumu starts stroking himself, and gasps as Akaashi starts moaning, "Harder, harder—ah! Hah, hah—ah!"
Is Bokuto's stroke game that good? Atsumu never would've guessed. He sure is learning a lot of things tonight.
A sharp crack sounds, loud enough to make it through the wall, and Akaashi cries out. Shit, did he just get spanked?
Atsumu squeezes the tip of his cock and bites back a moan, thrusting up to fuck into his fist.
"Fuck, you feel so good on my cock baby, you're so tight. Did you not fuck yourself at all without me?"
"No, no, only you—hnngh, hah—I waited for you. I only want you, I feel so empty without you, ah! Uh! Uh, nghh, you—oh, you're so good to me, please!"
Atsumu swears and starts jerking himself in earnest. He really hadn't thought listening to Bokuto and Akaashi would be this hot. He doesn't even remember being this turned on during his last hookup. Is that messed up?
"Yeah? Am I making you feel good, Keiji?"
"Yes, yes, oh my god, you make me feel so good, I love you so much," Akaashi sobs. "I love—hah! I love you, I love your cock, god, right there! Ah, ah, hah—"
A groan. "You're so beautiful, Keiji, you feel so good. Tell me—tell me more."
"Mmh, hnngh, you're—ohhh—you're incredible, you make me feel incredible, nobody could love me like you, nobody could fuck—ah! Hah! Nobody—Nobody could fuck me like you, I love you, want you to fuck me every day—ah—want you to use me like a slut, god! Hah, uh! Please come in me, wanna feel it, wanna feel you fill me up, nghh—"
There's an emphatic Fuck! from Bokuto and the thumping of the bed frame notably gets faster and more forceful. Holy shit, Bokuto and Akaashi fuck nasty.
Atsumu can feel himself starting to get close. He has to bite down on his lip and fight back a groan as he strokes himself fast, grip tightening on the upstroke, hips lightly kicking up into the pleasure.
"You gonna come, Keiji?" comes Bokuto's voice, breathless.
"Yes—ah! Y'r gonna make me come, I'm gonna come on your fat cock, please, hah, ah! Please make me come please—hah! Mmh! God, god, oh god, please, Bokuto-san! I'm gonna come—uh! Ah! Hah, ah! Bokuto-san!"
Akaashi continues to whimper through what sounds like the best orgasm of his life, maybe. Atsumu wouldn't know, he's about ten seconds from coming himself.
Bokuto moans and babbles Akaashi's name, and presumably also comes, but Atsumu doesn't hear it because with a few more strokes he's stifling a cry into his left hand as his cock jerks and spills all over his fist.
The orgasm crashes over him as Atsumu jerks himself through it, the pleasure bursting from deep within his gut and coursing through his whole body. He pants wetly into his left hand as he comes down from the high.
As he lays there in the aftermath, the post-nut clarity hits him with the full weight of what just happened. So he just jerked it to his teammate railing his boyfriend, great. That won't be awkward at all come morning when he has to see the two of them at breakfast.
On one hand, Atsumu really kind of needed that, after the game today. He's been a little pent up. On the other hand, this whole thing is so embarrassing that he's going to have to take this secret to the grave. If, god forbid, Osamu ever found out about this he'd still be laughing at him about it when they're 90 and rickety and he cannot let that happen. Otherwise, he can't guarantee he wouldn't accidentally beat his brother's ancient ass to death with his walking stick.
Maybe he needs to rethink this whole dorm situation, Atsumu thinks as he cleans himself off with a wet wipe. No way he's going out to the bathroom right now and risk seeing someone.
Tossing the wipes into the trash, Atsumu changes into new boxers and flops down onto his bed. His phone, laying forgotten under the covers somewhere, had long since locked itself.
Distantly, he can still hear Bokuto and Akaashi's voices in the next room over, quieter now than when they had been in the throes of their… coupling. Damn. Atsumu can't fucking believe Bokuto has a better and more active sex life than him, plus a boyfriend who says sappy shit to him in bed. Atsumu might need to up his own game, and isn't that an annoying thought.
The next morning, Bokuto's in the kitchen making breakfast when Atsumu wakes up. Frankly, Atsumu's impressed he managed to get up so early considering last night. It's not even 9 a.m.
"Mornin'," Atsumu greets as he starts getting out the ingredients to make a protein smoothie.
"Hey! Morning, Tsum-Tsum! How'd you sleep?" Bokuto asks, bright and perky as always. Seems like not even a potential hangover can dampen his mood at barely-9-on-a-Saturday. Then again, Bokuto had gotten laid last night, so maybe his chipper attitude is warranted.
"Slept like a rock, Bokkun." Atsumu glances at him out of the corner of his eye. Bokuto's making eggs for two, his hair still mussed from sleep and a mottling of deep bruises on the side of his neck.
"Oh yeah? That's good, the game really wiped you out, huh?"
"Yup." Atsumu takes out the blender from the cupboards and plugs it in before starting to scoop out some of the protein powder. "Ya seem full of energy for so early in the mornin'."
Bokuto takes out two plates and arranges a piece of toast onto each one. "Yeah! I mean, we lost but it was a good game, and I went out with Keiji after and celebrated his birthday since it's next week! So it was a good day, y'know?"
Atsumu snorts, tossing in some frozen strawberries and a banana. "Yeah, I'm sure it was."
Whatever Bokuto says in response to that is lost to the sound of Atsumu switching on the blender. Bokuto plates the eggs and adds a slice of ham on each before disappearing back to his bedroom with both plates. Must be nice to be Akaashi, getting dicked down for your birthday and waking up to breakfast in bed.
Ugh, maybe it finally is time for him to move out, Atsumu thinks, watching his smoothie swirl around and around.
And maybe get a boyfriend too.
