Work Text:
I.
It starts off innocently enough.
Yuusaku comes home one night after a very stressful day at work to find his older brother napping on the couch. It's not an unusual occurrence – Hyakunosuke works from home, and always at odd hours, so it's a regular occurrence to find him sleeping in the living room when Yuusaku gets home.
Something just feels... different today, though. Yuusaku is pent-up and sleep-deprived from pulling all-nighters while preparing his first board presentation since he'd moved out of the family home. He'd faced his father for the first time in months on that meeting, mere hours ago, and it hurt being regarded so coldly, like an utter disappointment, even as his presentation and diligence with his work garnered praise from other board members.
All things considered, Yuusaku was lucky for having only been asked to move out (though “asked” feels like an inapropriate euphemism, considering the rest of what was said that night). He managed to retain his position in the corporation, despite being functionally cut off from his family. This small grace obviously wasn't out of any personal consideration for himself, he knew that – public scandal was even more disgraceful than the family's sole legitimate heir being quietly gay, and Koujirou Hanazawa had to keep up the appearances to a degree. It wouldn't be the first time he threw a son away, but this one was a bit harder to hide.
Yuusaku quietly steps closer to the couch, towering over his sleeping brother. Hyakunosuke just looks— relaxed, calm. Deep in his slumber, slack-jawed and at peace. There isn't any trace of his learned indifferent expression, of a cruel sneer, of anything in particular. He's just sleeping. Maybe not even dreaming.
The night his father threw him out, Yuusaku had knocked on his brother's door without much hope. In a way, Yuusaku was the reason why Hyakunosuke wasn't a Hanazawa, was a living reminder of why he’d been rejected. It was surprising, then, that Hyakunosuke had looked at Yuusaku's lone suitcase and tear-stricken face on his doormat and stepped aside, letting him in without a word.
What was supposed to be a temporary fix, just until Yuusaku found an apartment for himself, was becoming more permanent by the day. Yuusaku likes it a lot, he has to admit – it's almost like he imagined during the lonely childhood years he'd spent desperately hoping and yearning for a brother. It’s the most comfortable domestic arrangement he’s ever had.
He sits on their coffee table facing the couch, careful not to make any noise that could disturb his brother. Hyakunosuke is sleeping on his side, uncovered – Yuusaku's fingers twitch with the urge to drape a blanket over his body, but he reigns it in. He's wearing the loose sweatpants and faded t-shirt he normally favours for lounging around the house, and his bare arms are in front of his chest, hands curled near his face. His breathing is steady, and a very light snore – more of a faint whistle, really – comes from his nose when he breathes.
It's a completely banal scene, nothing that should command his attention like this. Yuusaku knows it's impolite to stare, and even more impolite to stare at an unsuspecting sleeping person, but he can't help leaning closer.
It dawned on him at some point during the past weeks that Hyakunosuke is the one person in the world he could trust right now. His father won't talk to him, his mother is in a difficult position, caught in the middle of their conflict, and the friendly relations he's gathered throughout the years are just that – friendly, but not exactly friends. Even with all the resentment Hyakunosuke undoubtedly feels towards Yuusaku and the Hanazawas, he still opened the door that night. He still let Yuusaku stay and build something he could tentatively call a home in his cramped apartment.
Yuusaku only realizes he's reached out towards Hyakunosuke's face when the warmth of his skin seeps into his fingers, and Hyakunosuke stirs a little in his sleep. Yuusaku pulls his hand away quickly, in shock of what he's so carelessly done, and holds his breath in anticipation for Hyakunosuke waking up and realizing what he'd been doing. Staring at someone while they sleep is one thing, but touching them is a step too far. Seconds pass like hours, as Yuusaku waits for his brother to wake up and curse him out.
It never happens. Hyakunosuke shifts on the couch and settles on his back without waking up. His left cheek has some red pillow marks on it from being pressed against the cushions, and he keeps sleeping as if nothing had happened. Yuusaku sighs in relief. That was a close call. How would he even explain himself, if Hyakunosuke had woken up to Yuusaku's hand on his face?
Yuusaku gets up quietly, and pads over to the kitchen to fix them a quick dinner. Hyakunosuke wakes up some time later and joins him, once the smell of cooked fish wafts over to the living room, and it doesn't look like he knows anything of what transpired. The incident is eventually forgotten by Yuusaku, as well, and soon it's like it never happened.
II.
A few days later, Yuusaku is suddenly woken up in the middle of the night by the doorbell ringing incessantly. A glance at his alarm clock reveals it's two in the morning, and he lets out an incredulous groan before getting up to answer the door.
He opens it to find a very intoxicated Hyakunosuke slumped heavily over the shoulders of a man Yuusaku's never seen before. The man has strangely symmetrical moles on his cheeks and an unsettling presence, and Yuusaku kind of regrets not putting on a cardigan or something to shield his bare arms from the man’s unnerving eyes.
"You must be Ogata's baby brother, right?" the man asks, rearranging the inert body he's supporting to offer Yuusaku a handshake. "I'm Usami, Hyaku's best friend. He must've told you about me!"
"Ah," Hyakunosuke’s never mentioned anyone with that name before, and Yuusaku has a hard time imagining why he would hide a best friend’s existence from him. "Not... Not really? But... nice to meet you, Usami-san."
Usami unceremoniously shakes Hyakunosuke off his shoulders, almost letting him fall to the ground, and Yuusaku has to quickly step over to catch him.
"This one had too much to drink, obviously," Usami shrugs, rearranging the collar of his shirt. "Sorry to drop him over like this, but he was kind of ruining the vibe at the bar."
Hyakunosuke mumbles something against Yuusaku's shoulder, body still limp and supported by Yuusaku's arms hoisting him up by the armpits. Usami leans into the doorsill, now really ogling Yuusaku unashamedly.
"...You know, I always wondered why Hyaku never talks about you," he says, a playful drawl on his tongue, "but now I can see why he'd want to keep you all to himself."
Something hot and uncomfortable crawls up Yuusaku's neck from how dirty Usami made this sound. He hurriedly pulls Hyakunosuke inside, propping him against the wall so the door can be shut.
"Thank you for bringing ani-sama here, Usami-san," he says politely, wanting to shut off this creepy stranger that somehow was his brother's friend as fast as possible. "I don't want to make you miss even more of your night out, so..."
"It's no problem at all! It's my pleasure." Usami tilts his head. "We could get to know each other better, how about that?"
What a pushy guy! Can't he see that Yuusaku was woken up quite suddenly, and is in no state to chat while his almost-unconscious older brother is sliding down the wall to join the shoes lined up on the genkan? Plus, it's two in the morning! Not exactly the time to get to know someone!
"Maybe some other time?" He starts closing the door slowly, but Usami doesn't budge. Unfortunately, he's going to make Yuusaku shut the door practically on his face. "Have a good night, Usami-san."
The last thing Yuusaku sees from the slit of the door being shut is half of Usami's unsettling grin. "Good night, then, little brother!"
Yuusaku holds the door closed until he hears Usami's footsteps fade in the distance. That was weird. Hyakunosuke is dangerously close to toppling over and face-planting on the floor, so Yuusaku kneels next to him and holds him upright.
He's really out of it. He reeks of cigarettes and alcohol, his clothes are in disarray, and his hair is falling out of its meticulous slicked-back style. As he removes Hyakunosuke's shoes from his feet, Yuusaku ponders if he should shake Hyakunosuke awake so he could urge him to drink some water and have a quick shower before bed, or if he should just let him sleep as is.
"Ani-sama?" he calls. Hyakunosuke grunts in response, but doesn't open his eyes. "Ani-sama, are you alright?"
He slumps against Yuusaku's shoulder again, and Yuusaku resigns to just carrying him to his bed tonight. He can leave a tall glass of water and some aspirins on the bedside table for when Hyakunosuke wakes up later.
Yuusaku drags his brother to bed, making him sit up as he removes his jacket. Hyakunosuke hums a little tune as he does that, and it gives Yuusaku pause. He must be really, really drunk – the tune is some old lullaby that Yuusaku remembers vaguely from when he was little.
It's heart-warming, Yuusaku thinks, that even when living two vastly different lives apart they both knew this song.
Yuusaku helps Hyakunosuke lay down with his head resting on the pillows, and goes to fetch the glass of water in the kitchen. When he comes back, he finds Hyakunosuke struggling to unbuckle his belt and shimmy out of his jeans at the same time, his brow furrowed with the effort.
He sighs in amusement at the sight. It's a rare thing, seeing Hyakunosuke being so silly. "Here, ani-sama, let me help you."
Yuusaku unclasps the belt and unbuttons his brother's jeans, pulling them down carefully. He tries not to take notice of his legs, muscular and hairless, so pale in the dim light. He's never seen so much of Hyakunosuke's body before.
He folds the pants and sets them on a nearby chair, and makes to get up from the bed and leave Hyakunosuke to sleep off his drunkenness. However, a surprisingly strong hand grabs him by the wrist and stops him.
"Stay," Hyakunosuke croaks out, voice muffled by the pillows he's pressing his face against.
Yuusaku falters. This... Is this alright? Sleeping on the same bed is a little... No, he shakes his head firmly, I’m not going to make this weird. He's tired as well, after being woken up so rudely and so late, so he gives in and lays down besides Hyakunosuke, only stopping to turn off the desk lamp.
Hyakunosuke immediately latches onto him, warm body pressed against his, and Yuusaku can barely suppress a shudder. Their legs tangle together, and Hyakunosuke's arm drapes across his waist as his head rests on Yuusaku's shoulder. It's too warm, too close, but Yuusaku can't help feeling... excited.
Ever since he realized he was gay, Yuusaku has never allowed himself to touch other men, even casually. He felt like they could somehow tell what he was, if he let his touch linger for a bit too long, press a bit too far.
This... this is completely new. It feels comfortable, like he belongs there in his brother’s arms.
Yuusaku drifts into sleep to his brother's soft, rhythmic snores, indulging himself just this one time. Just for tonight.
III.
Yuusaku wakes up to something hard insistently poking his lower back. It’s still too early, he can tell from the very faint light escaping through the gaps in the curtain, and he’s too sleepy still, not fully aware of his surroundings.
Oh, right. Hyakunosuke had pulled Yuusaku into his bed the night before. He was very drunk, and a bit more handsy than usual, but Yuusaku had allowed it. They had cuddled, Yuusaku’s mind supplies, though it seems like they had changed positions during the night. Yuusaku fell asleep on his back, but now he’s on his side, pressed close against Hyakunosuke’s front. Hyakunosuke’s arm is thrown around his midsection, their legs tangled. Yuusaku reflexively reaches behind himself to push away the offending object that’s poking him so he can go back to sleep, but freezes when he finally realizes what it is.
Currently, Hyakunosuke is grinding his very hard cock against Yuusaku’s back.
Yuusaku stiffens, mortified. This shouldn't be happening. He inches forward slowly, so he can slide off the bed without waking Hyakunosuke up. It's an unimaginably awkward situation, and he doesn’t want Hyakunosuke to wake up during this and feel embarrassed by a completely involuntary physiological reaction. Yuusaku just needs to slide out of his reach, and then he can forget his ever happened.
Hyakunosuke seems to notice even in his sleep that his heat source is going away, though, because he grumbles and pulls Yuusaku closer again, undoing all of Yuusaku's progress in putting some distance between them. His grip is surprisingly strong, too, and Yuusaku isn’t sure if he can extricate himself so easily now.
It's probably best to wait until Hyakunosuke changes position by himself again. Yuusaku sighs - all this scooting back and forth only worsened the situation, and now Hyakunosuke’s cock is pressed right up against the cleft of Yuusaku's ass. It’s a nightmare, and it’s heightened by the fact that Yuusaku’s body is reacting to all this rubbing and touching, too.
He tries to will his increasingly hardening dick to soften back down, but it's of no use – Hyakunosuke's chest pressed against him, their bodies only separated by the thin layers of his underwear and Yuusaku's pajamas, feels heavenly. It’s like nothing he’s ever experienced before. The solid weight of Hyakunosuke's body, the ripe smell of his unwashed skin right up against Yuusaku’s... it's all warm and comfortable and Yuusaku wants to get lost in it despite all logic telling him this is wrong and dirty and that he should get away as soon as possible.
"... Anisama?"
No answer. Not even a change in the pattern of his snores. Hyakunosuke must be a very heavy sleeper, then... even more so when drunk...
Yuusaku reaches back to jostle him lightly on his shoulder, and there's no response. Yuusaku's treacherous thoughts go wild – if Hyakunosuke wouldn’t wake up even when shaken like that, then maybe... maybe he could...
He arches his back, experimentally, towards Hyakunosuke, pressing his ass back. The groan Hyakunosuke makes near his ear in response is enough to make Yuusaku shiver from head to toe, biting down a shaky whimper. It feels so good, to press up against a warm body. He's only ever had his own hand and pillows before – these things can’t even compare to the feeling of Hyakunosuke’s hard cock grinding between his ass cheeks, his strong arms wrapped around him, his hot breath on his neck.
Yuusaku palms his own dick, his body falling into some sort of rhythm with Hyakunosuke’s disjointed thrusts. It's too much, and yet not enough – he has to feel Hyakunosuke’s bare skin against his, wants to, needs to...
He reaches and pulls down his pajamas and underwear, just enough to bare his ass and cock. With shaky hands, he blindly goes to lower Hyakunosuke’s underwear, too.
It’s so, so warm, Hyakunosuke’s cock in his hand. Hyakunosuke makes little sounds in the back of his throat, sounds he wouldn’t dare make while awake, as Yuusaku spreads the precum that gathered on the head of his cock to slick the length.
He shouldn't. Oh, he really shouldn't. Hyakunosuke could wake up any minute...
Hyakunosuke humps against his hand once more, and it’s what does it for him. Yuusaku guides his brother’s cock in between his legs, flush against the back of his balls, and squeezes his thighs together.
Ah, ahh, it feels so good, so impossibly good. Hyakunosuke’s precum and the sweat on Yuusaku’s body make the tight channel between his thighs slippery, perfect to be thrust into with reckless abandon. If it was difficult for Yuusaku to keep quiet before, now it’s impossible – breathless moans fall from his open lips, as if punched out of his lungs.
Asleep, Hyakunosuke misses every other thrust, sometimes slipping out completely and making Yuusaku have to guide him in between his thighs again. It’s so good, though, the drag of his warm cock on Yuusaku’s balls, on his sensitive taint, sometimes catching on the rim of his hole and making him shiver. He could fuck me like this, he could fuck my ass like this, Yuusaku’s mind conjures feverishly, ani-sama could fuck me like this and I wouldn’t be able to do anything about it—
He squeezes his brother’s cock, drinks in his gasps and moans, unfiltered by consciousness or awareness. Maybe Hyakunosuke’s having a very nice dream right now, with his body going along with it. Yuusaku wonders if he could ever be a protagonist in his brother’s dreams, in those kinds of dreams. If Hyakunosuke would ever want to see him like this.
Yuusaku doesn’t feel his orgasm coming until the moment it washes over him, breathless and unexpecting. His toes curl, his asshole clenches around nothing, I wish he was fucking me, and Yuusaku almost blacks out for a moment. Through the haze he feels Hyakunosuke’s hand squeeze his hips, bury his cock in the channel of his thighs, making a mess as he comes, too, all over Yuusaku’s thighs and balls.
He... He really did it. Terror slowly seeps into Yuusaku’s post-orgasmic daze, as it dawns on him the weight of what he’d done. He... He took advantage of Hyakunosuke, didn’t he? The sweat from the physical exertion cools on his skin, making him shiver.
This is bad. So horribly bad. How could he have allowed himself to do this? To take advantage of Hyakunosuke’s vulnerable state like that? The room is so deadly quiet, now, disturbed only by Yuusaku’s increasingly panicked breathing.
Maybe Father was right, when he cursed him out of the house and called him a sick pervert. If he wasn’t fit to be a son, what made him think he’d be fit to be a brother?
Yuusaku scrunches his eyes closed, trying not to cry, and fails miserably at it. His shoulders start to shake with sobs, as panic and self-loathing and shame overwhelm him.
“Yuusaku, breathe.”
His eyes shoot open when he hears Hyakunosuke’s sleepy, slightly hoarse voice. He tries to turn around, to explain himself, to beg for forgiveness, but Hyakunosuke just tightens his hold on his midsection, keeping him there.
“That was a nice thing to wake up to,” Hyakunosuke hums, punctuating his sentence with a weak movement of his hips. His soft cock is still nestled between Yuusaku's thighs, and the easy slide of it, the evidence of what happened, makes Yuusaku want to cry harder. “I’d go for seconds if I wasn’t so hungover.”
“S-Seconds...?”
“Did you come?” Hyakunosuke ignores Yuusaku’s question and moves his hand lower, and Yuusaku can feel a lazy grin press against his shoulder blade when his fingers find the shameful wetness on his cock. “Wish I could have seen that.”
“Ani-sama, I’m s—”
“Let me sleep for a little longer?” Ogata yawns. He’s still cupping Yuusaku’s spent cock and balls, just as he was holding his waist moments before. It’s... nice. Awkward, but feels nice. “Talk later. I’m not mad at you.”
Hyakunosuke nuzzles into the back of Yuusaku’s neck, tangles their legs together again. Yuusaku slowly starts to calm down, reassured by his brother’s words, but it takes a while before he can relax enough to go back to sleep.
IV.
Things between them stay mostly the same after that, to Yuusaku’s surprise. He still goes to work every morning and comes back every evening, still prepares bentos for the two of them so Hyakunosuke won’t start subsisting on instant ramen and take-out again; Hyakunosuke still greets him when he gets home, if he isn’t napping; still silently helps with chores, though Yuusaku effectively does most of them. They still eat dinner together, and Yuusaku chatters about regular office gossip as Hyakunosuke sometimes interjects with a sarcastic remark. They’re living like normal, like nothing had happened.
Except for when Hyakunosuke slips into Yuusaku’s bed in the middle of the night, that is.
(“Doesn’t it bother you?” Yuusaku asks timidly, not daring to look up from the bedcovers.
Hyakunosuke swallows the aspirins and drinks from the glass of water Yuusaku brought him. “Hmm?”
“The... what we just did...” Yuusaku brings his knees closer to his chest, still feeling the stickiness between his legs even though Hyakunosuke had wiped it with his bedsheets. He’ll have to throw those in the wash later. “Doesn’t it bother you? You were asleep, and I—”
“It doesn’t bother me,” Hyakunosuke interrupts him with an impatient huff, “and if you think about it, it was I who did stuff to you, so don’t feel so guilty.”
“But—”
“Besides, I think it’s hot,” Hyakunosuke shrugs and stretches his arms above his head, and Yuusaku is distracted by the way his t-shirt rides up. Hyakunosuke notices it, of course he does, and smirks teasingly. “Wake me up with a blowjob one of these days, I’d like that.”
“Ani-sama!”)
A few nights a week, Hyakunosuke slips into Yuusaku’s bed, and they do... stuff. Nothing too different from what they did that first time, and it feels good, better than Yuusaku could ever imagine, though deep in his heart he desperately wants more.
Am I being too greedy? He wonders, awake in bed during a night Hyakunosuke is working late. He can sort of hear the clacking of the keyboard through the wall, as Hyakunosuke quickly types up lines of code. Maybe, uhm, hands are all ani-sama is willing to give me, which is... fine, I guess.
Hyakunosuke’s hands are always wonderful, whether grasping his cock firmly or caressing his skin, but... Just them doesn’t feel like it’s enough, for Yuusaku. He thinks back on that first night, of that desperate need of being filled, of being fucked – how would he even bring up something like that with Hyakunosuke? When they don’t even talk about those nights?
Yuusaku reaches down into his pajamas, brushing the pad of his pointer finger to the pucker of his hole. He shudders a little – it feels strange, but nice. It definitely feels less nice when he pushes the finger in, though, and it’s such a tight fit to the first knuckle that he can’t imagine how he could fit the rest of it, let alone... something else. He takes the finger out and goes back to just touching himself on the outside, rubbing the sensitive skin behind his balls, and soon Yuusaku is fully hard and much hornier than before.
He’s so worked up from touching himself that he doesn't even hear Hyakunosuke’s keyboard falling silent in the next room, and doesn’t hear the door to that room opening and closing. Yuusaku’s only warning before Hyakunosuke enters his room is the door opening, and by then it’s too late to try to hide what he’d been doing.
“Got started without me?” Hyakunosuke teases, no real heat behind his tired voice. He really had been working too hard today – something about a big commission job that was too last-minute to get done without crunching. Yuusaku came back from work that evening and found Hyakunosuke in the same position he’d left him that morning, hunched up in front of the computer.
“Ah, ani-sama—” Yuusaku squeaks, embarrassed to be found like that. Hyakunosuke wordlessly walks to the bed and slides under the sheets, holds Yuusaku against his chest with a weary sigh.
He must be so tired, Yuusaku thinks to himself. Hyakunosuke probably just wants to cuddle and sleep after a long day of work... And here he is practically imposing his horniness upon his brother.
“I... I could deal with this in the bathroom, so we can sleep...?” Yuusaku asks, but Hyakunosuke just keeps holding him there.
“What are you talking about,” he yaws against Yuusaku’s skin, “just do it here with me.”
Yuusaku hesitates for a moment. Hyakunosuke huffs.
“Just because I’m too tired to do anything now,” Hyakunosuke explains, hand caressing Yuusaku’s side, “doesn’t mean I wouldn't appreciate seeing you enjoy yourself.”
“Ah. Uhm, OK,” Yuusaku reaches back down into his pajamas, and releases a shaky sigh when he finds himself just as hard as he was before he was discovered. Hyakunosuke’s hand is warm on his hip, and his t-shirt is soft, and Yuusaku was already sort of worked up so it doesn’t take long before he’s coming with his brother’s name on his lips.
Hyakunosuke pulls him close again, tucking Yuusaku's head under his chin.
“Goodnight,” he hums.
“Goodnight, ani-sama,” Yuusaku replies. He reckons it doesn’t take much more than a couple minutes till Hyakunosuke’s soft snores fill up the room. He follows soon after.
V.
Hyakunosuke’s louder-than-usual snores wake Yuusaku up way earlier than he’d like. He spends a few moments trying to go back to sleep through sheer force of will, but it’s of no use. He turns to Hyakunosuke to find him sleeping on his back – which explains the level of his snores this morning. They aren’t house-shakingly loud like Father’s, but still aren’t easy to ignore.
In these few days where they’d been regularly sharing a bed, Yuusaku had found that turning Hyakunosuke on his side normally worked to combat loud snores; Hyakunosuke doesn’t even wake up when he does that, and it gives Yuusaku the opportunity to be the big spoon for once. He’s about to gently push Hyakunosuke’s shoulder to do just that, when something distracts him.
The thin sheets do nothing to hide the rock-hard erection Hyakunosuke is currently sporting. It occurs to Yuusaku that he’s never actually seen it – he’s touched it plenty, but never saw it with his own eyes. He sits up on the bed, trying not to move the mattress too much.
How come Hyakunosuke is always asleep when these sorts of thoughts come to him?!
Hyakunosuke shifts in his sleep, legs spreading the slightest amount, the sheet sliding down his body and revealing a tantalizing strip of skin where his t-shirt has ridden up. He turns his face left, and it somehow helps with the snores .
“Wake me up with a blowjob one of these days,” Yuusaku remembers Hyakunosuke saying just a few days ago, “I’d like that.”
Would it really be OK, if he did that...? Yuusaku kind of really, really wants to. It’s almost embarrassing that he can feel his mouth water with just the thought of tasting it. And it would make his brother feel good, wouldn’t it? Even though Yuusaku doesn’t have any experience with that, he’s got some rudimentary notions established. Enough not to make a complete fool of himself, at least.
He inches closer, briefly pondering if he should push the bedsheets away before deciding on just getting underneath them – the last thing Yuusaku wanted was his brother to wake up feeling cold.
Hyakunosuke is only wearing his socks and underwear, so the obstacles in Yuusaku’s path are very few. He settles between his thighs, laying on his stomach, and carefully hooks his fingers on Hyakunosuke’s waistband, pulling his boxers down.
It’s a cock, alright. Not much different from his own, though Hyakunosuke’s is slightly shorter. Yuusaku wonders if it’s weird that he likes the way his brother smells so much – the natural musk of his skin, so masculine and good and addicting. He can't help breathing heavily, soaking in it. Hyakunosuke’s cock is warm and heavy on Yuusaku’s hand when he touches it, wrapping his hand around the length and stroking it tentatively.
From underneath the sheets Yuusaku can’t see Hyakunosuke’s reaction, but a hitch in his breath as he sleeps is enough of a stimulus to embolden him. He tries to think of vague advice he read in a women’s magazine many, many years ago when he was sneaking a peek at it at a newspaper stand – cover your teeth with your lips, use your tongue, don’t try to take too much at once – and takes the head of Hyakunosuke’s cock inside his mouth.
It’s good, the salt of his skin on Yuusaku’s tongue, how comfortably it fits, and Yuusaku can’t help taking it a little bit further, swallowing his brother’s cock completely, breathing through his nose and burying it in Hyakunosuke’s pubic hair. He bobs his head experimentally, and is amazed at the effect it has on his brother – he’s so conscious of the flex of the muscles on Hyakunosuke’s thighs, the curl of his toes on the mattress, the soft moans Yuusaku can hear spilling from his lips.
He builds a rhythm, adapting depending on how Hyakunosuke’s body responds – it’s so intoxicating, being so viscerally connected, and Yuusaku can’t help grinding his own hard cock against the mattress. His mind drifts to his fantasies from the night before, to how it would feel to bury Hyakunosuke’s cock inside his ass instead of his mouth, and just imagining it makes him moan around Hyakunosuke’s length.
Yuusaku gets so into it that he only realizes Hyakunosuke’s woken up when the sheets over his head are unceremoniously pushed aside, letting him see Hyakunosuke’s flushed (he’s so cute, oh my god) expression, as he props himself on his elbows to look at Yuusaku better.
“Where the hell did you learn how to do that,” Hyakunosuke groans, voice rough from sleep, as he pushes his messy hair back and away from his eyes unsuccessfully.
“Hmm?” Yuusaku releases Hyakunosuke’s cock with a wet pop to answer his question. “I read—”
“I didn’t say you could stop, God,” he hisses, hand immediately reaching to push Yuusaku’s head back down. “I’m so close—"
Yuusaku redoubles his efforts, taking Hyakunosuke deeper, swallowing around his cock and trying to push the right buttons again. Hyakunosuke’s hands don’t leave his hair, but he’s not pulling on it – he buries his hands on the strands, cursing under his breath as Yuusaku sucks him off. His free hand, Yuusaku notices in the periphery of his vision, is grasping at the sheets beneath them tightly.
Without giving it much thought, Yuusaku grasps Hyakunosuke’s free hand with his own, untangling his fingers from the fabric and interlacing them with his. Hyakunosuke’s grip is tight, bordering on painful, and he falls back on his pillows and arches his back as Yuusaku bobs his head once, twice, before a shaky moan tears itself from his throat and he comes in Yuusaku’s mouth.
The taste is kind of overpoweringly salty and strong on Yuusaku’s tongue, but he doesn’t even consider not swallowing it all down, licking Hyakunosuke’s softening cock clean until he’s finally pushed away.
They take a moment to catch their breaths, Yuusaku’s head resting on Hyakunosuke’s stomach as he waits for Hyakunosuke to recover. Their hands are still clasped together, sweaty and slippery, and it hits Yuusaku that it’s the first time they do this – the first time they ever held hands.
“C’mere,” Hyakunosuke whispers, and Yuusaku is quick to obey, draping himself over Hyakunosuke’s body, careful to not break the interlacing of their hands.
It takes his breath away, how Hyakunosuke looks – eyes half-lidded, pupils blown huge and pale skin flushed and mouth open and—
“Kiss me, idiot,” his brother orders with an unguarded smile Yuusaku has never seen on his lips, ever, and he’s quick to obey again and again, their first kiss stretching long in the brief space between their beating hearts.
Hyakunosuke’s knee finds Yuusaku’s cock, still hard inside his drenched underwear and pajama pants, and Yuusaku feels a mischievous smile tug at the corner of his lips.
“Gimme a minute or two,” he says against Yuusaku’s mouth, his warm breath a promise, “I’ll take care of you too.”
Yuusaku keeps kissing him, unhurried. He’s already gotten way more than he had thought Hyakunosuke was willing to give him, anyway – it wouldn’t be too hard to wait just a little longer.
VI.
“Hey,” Hyakunosuke says later, over the mug of coffee Yuusaku poured for him. “Yuusaku.”
