Chapter Text
Sae Itoshi wasn’t known for making many mistakes in his life and he took great pride in that fact. Thanks to that, he doesn’t have much to regret either. That applies to every part of his life. Well, almost.
There is one annoying bug in his world of peace and quiet that he is just unable to smash.
Ryusei Shidou is a goddamn hurricane, a force of nature just like Sae himself but his polar opposite. No matter how hard Sae tries to ignore or lose the guy, he just keeps bouncing back with twice as much force. His endless teasing, unabashed flirting and dirty slurs annoys Sae to no end, and though he does his best not to let it show, there are slip ups.
When it comes to Ryusei Shidou, Sae tends to make many mistakes.
The first one was giving him his phone number, no doubt. Sae knew it would be a bad idea, but he couldn’t go back on his word, even though the pink devil didn’t score three goals per se.
However, he was definitely not prepared for the amount of spam messages he would get. Really, the guy was insane and Sae had to seriously consider the possibility of changing his phone number.
The text messages ranged from utter nonsense like a flurry of emojis through stupid greetings like ‘Good morning Sae-chan, have a beautiful day~~! to ‘seeing that close up of your ass made me cum in my pants’. It was really too much for Sae to handle, so he did what he did best: pushing through with gritted teeth and winning.
He had made it his mission not to let Shidou have the upper hand, catching him off guard as often as possible and forcing him to step up his game. Sae was determined to ignore the fact how it looked as playing along, because he did not do that, he was simply giving the demon a taste of his own medicine.
That has led straight to the second mistake: agreeing to take a bet.
“We’re gonna have so much fun, Sae-chan!” Shidou exclaims loudly while throwing himself at Sae, who gracefully sidesteps just in time, making Shidou stumble forward.
Sae takes a deep breath. Yes, he knew that taking stupid bets with Shidou was a terrible idea and would lead straight to disaster, but he was really sure scoring ten fucking goals in one match would be impossible… and Shidou somehow fucking pulled it off?! Sae would be impressed if he wouldn’t be totally screwed.
This is going to be such a pain, but he takes defeat with dignity. Also learnt his lesson and swore never to take any bets with Ryusei Shidou ever again.
Surprisingly, living together isn’t as much of a pain as Sae has expected it to be. Which he would never admit aloud, but he can admit it to himself at least. He doesn’t like how often he is proven wrong, as it is almost always the case with anything concerning Shidou.
He has expected it to be a major annoyance and had like ten plans ready as to how to kick him out, without being accused of cowardice. Not that he planned backing out on his word but still… just finding a loop in a terrible contract, Sae surely couldn’t be blamed for that. Right?
However, living together with Shidou turned out to be surprisingly easy. He is still Shidou, loud and annoying, teasing Sae endlessly with dirty innuendos and making lewd comments about his thighs at least twice a day, but otherwise? Damn, the guy is attentive.
Ryusei makes sure they never run out of oat milk, since Sae preferred his morning smoothie with it, he mops the floor after showering, knowing Sae would get really annoyed if he stepped into water with his socks, and he keeps his distance whenever Sae has an important match or an annoying meeting coming up but he makes sure they eat his favorite food afterwards.
In exchange, Sae tolerates him trotting into his room like he owned the place and declared it sad only to turn up with a fucking house plant the next day.
“You’ll feel lonely when I’ve got an away game, so little Ryuu here will keep you company~” Ryusei introduces the plant as if holding a kitty and holds it out for Sae who spares it a glance than stares at Ryusei, unimpressed.
“Oh, c’mon, I know you like ‘im. It’s a Flaming Katy but we’ll call him Flaming Ryuu, he’s our first baby!”
“No.” Sae deadpans.
“Pretty please? Let little Ryuu stay with you.” Ryusei is staring at him with puppy eyes, edging closer and practically showing the stupid plant into his face. “He is so lonely, look at those sad little flowers!”
Sae rolls his eyes, because there are simply flowers, not sad neither happy. Still, he pushes it away more carefully than he’d like to admit and sighs in defeat, gesturing towards the windowsill. “Fine, put it there.”
Ryusei’s face lights up and he immediately hurries over and places the plant gently to where Sae is pointing. “You’re gonna love it here, little Ryuu, don’t worry, Sae-chan will take good care of you~” He coos, petting the leaves affectionately.
“Ryusei.”
Ryusei turns around, his smile wide and eyes sparkling. “Yes, my dear?”
“Get out.”
His grin widens but he complies, and Sae is all too aware of losing yet again against Ryusei and his stupid grin and stupid impulsive acts.
It isn’t anything special, a common houseplant going by the name Flaming Katy which Sae did absolutely not Google, and it has pink flowers, of course, to remind Sae of Ryusei when he is away – his words, not Sae’s. After getting over Ryusei’s blatant breach of his privacy again, his fucking obsession of knocking Sae up as if it would even be possible, Sae finds himself smiling at the plant. It is kind of cute.
He has started to learn a few things about Ryusei, seeing past the annoyingly loud, horny idiot persona. One of those surprising discoveries is the fact that Ryusei can cook. He isn’t a chef and rarely has time for cooking, but the meals he prepares are delicious, even if they look like they came straight from hell. Well, considering a demon made them… Sae chuckles at his train of thoughts. Then looks horrified. Fuck, he is losing it.
Sometimes Sae would come home finding the place completely empty and quiet, Shidou being away in another country or at the gym, but sometimes Sae comes home to some really absurd scenes.
Shidou wearing headphones and going around watering the plants which he just kept buying and filling up the living room, screaming along the lyrics of a Celine Dion song from the bottom of his lungs, other times having a fucking rave party by himself while cooking, yelling things like “Gordon Ramsey can suck my dick!” and “Fuck, this pasta will get us both pregnant!”
More often than not Sae needs all his willpower to suppress a chuckle at how this idiot behaves. Seriously, who does things like that? Deep down he is a little bit envious of how carefree Ryusei is.
It is dangerous. Wanting. Sae knows it. He is way too aware of just how his feelings started shifting ever since Ryusei has come into his life. Well, barged into to be precise. Even Sae was surprised by how well he could tolerate him, and sometimes even had fun with him, outside of the soccer field.
Sometimes Ryusei would come up with a random activity, and sometimes Sae would agree, just to spare himself the whining and begging Ryusei almost always did when Sae was reluctant about spending time with him.
And that’s how Sae ends up on one end of the couch at a Saturday night, while Shidou is sitting on the other end, having a damn Star Wars movie night with popcorn, nachos and drinks covering the not so small coffee table.
They are both on a diet but on rare occasions, it is fine to indulge in some snacking and Sae is just too tired to care. He refrains from pointing out that they already had a cheat day when Ryusei impulse bought a shit ton of churros on his way home from practice last week. Sae might have an inhumane amount of self-restraint but hey, churros is churros.
“Damn, I’d totally bone Mark Hamill in his prime.” Ryusei’s dirty comment snaps Sae back to reality but he keeps staring at the screen unimpressed, not even sparing Shidou a glance. That doesn’t bother him, not that it ever did, and continues. “Luke’s got that cute innocent vibe, you just wanna ruin him.”
Sae doesn’t give him the satisfaction of any reaction, so Ryusei keeps going. “Leia is pretty hot, too, but her peak is def that slave outfit.” Ryusei snickers. “No wonder they are siblings, damn, I wouldn’t mind that sandwich.”
“You do know the actors aren’t related.” Sae points out calmly, still not looking at Ryusei.
“So? I’d still fuck them, A+ casting.” Ryusei shrugs, then sits up with a grin. “But don’t worry Sae-chan, you’re still my number one.”
“How flattering.” Sae says bored.
“Who would you bang tho, hmmm? Luke or Leia? Or both?” Ryusei leans forward, grinning conspiratorially.
With Ryusei’s pink eyes staring a hole at him, it is increasingly difficult to concentrate on the movie. Sae rolls his eyes. “Not everything is about sex, you horny demon.”
Ryusei barks a laugh. “That’s cuz your life is boring, but fear not, I’m here to save you, princess” He teases with a laugh before getting back to the topic. “I’d go for both, have a nice threesome. Han shoulda taken his chance, fuckin’ idiot.”
The movie continues in silence for a few minutes before Sae decides to play along, because why not? It is getting late, he is tired, he is getting comfortable sinking into the soft cushions and watching a movie together is actually fun.
And because he just can’t back out of a challenge brought by Ryusei Shidou, no matter how stupid it is. Sae is kind of curious where this whole, well, thing? is heading.
“I’d choose Han.” He says out of the blue and Ryusei nearly chokes on his drink.
“What?!” He shouts in a dramatic way, but then his smug grin appears, splitting his face. “Bad boys, huh? I knew I was your type!”
“Oh shut up, demon, or I’m going to sleep.”
Ryusei barks another laugh but has the common sense not to push it. Sae suppresses a smile. Living together with Ryusei is indeed fun.
Sae doesn’t want things. He sets his eyes on a goal and makes it happen. His philosophy applies to both on the field and in life. That was the case, until Ryusei Shidou happened. It is dangerous. It is scary. It is a total mess. And it definitely makes something in Sae’s chest clench, in a painful yet exciting way.
Sae hates to feel this lost. Not knowing what he wants but wanting it badly, and it all revolves around Shidou. His stupid eyeliner and ridiculous hair and annoying smug smile, teasing Sae with dirty jokes that make his body hot all over and his cheeks flushed.
And as always, Sae does not shy away from a challenge, he plans to tackle it head on, not exactly realizing what that would mean. He just wants this uncertainty to stop, his raging feelings to calm down, so he can think clearly again.
So when one day Ryusei saunters into the living room after showers, wearing nothing but a towel wrapped loosely around his waist, Sae allows himself to stare.
“Like what’ya see pretty boy?” Ryusei teases, grinning smugly and swaying his hips as he pushes his wet hair back from his face.
Sae keeps staring for another few seconds before getting up and walking to Ryusei, who is still grinning but surprise flashes in his pink eyes.
Sae could later claim he was being possessed, but now he sees a perfect opportunity to catch Ryusei off guard and pay back for, well, for everything really.
Sae’s eyes bore into Ryusei’s, causing him to swallow, grin frozen and eyes wide, like a deer caught in headlights. Good, Sae thinks.
“Don’t touch me.” Sae’s tone is quiet but firm, and before Ryusei could even open his mouth to ask what that means, Sae drops to his knees in front of him and pulls the towel off unceremoniously.
He takes Ryusei’s cock into his hand, giving him a few experimental tugs and pumps before sticking his tongue out and licking the head.
“Fuuuck!” Ryusei gasps and his whole body shudders. Sae grins to himself, careful not to let Ryusei see it. Instead he glances up at Ryusei, locking eyes with him as he opens his mouth properly and takes him into.
“Ugghh… Sae-chan, shit-!”
From the corner of his eyes Sae sees Ryusei’s hands reaching for his head and with a surprising amount of willpower, stop. Ryusei clasps his hands behind his back, clearly suffering from not being able to touch Sae and Sae takes a sick amount of pleasure in Ryusei still obeying him against his instinct. It is such an unexpected power trip that Sae is starting to get hard. Well, shit.
When he is sure that Ryusei would behave, he wraps a hand around the base of his cock, while guiding it deeper into his mouth, his other hand gripping Ryusei’s hip to steady them both.
“Fuck, Sae, feels so fucking good, oh gods, you’re the best, shit, suck me harder, please, please, please.” Ryusei is reduced to a gasping, moaning mess in record time and though Sae takes some credit for the blowjob, he knows it is probably thanks to the foreplay that started when they have first met. On Ryusei’s side, at least.
It is a bit difficult to take Ryusei’s whole length into his mouth but Sae will be damned if he doesn’t execute his plan flawlessly. When Ryusei’s hips buckle a little, he does grunt warningly but doesn’t pull back, working through his choking by sheer determination.
Even lost in chasing pleasure, Ryusei understands that he is not allowed to do that again. “Shit, sorry, ‘m’sorry.” He is quick to apologize, which Sae rewards with hollowing his cheeks and taking more of him into his hot mouth, saliva trickling down from his mouth.
Then Sae starts moving his head back and forth, sucking eagerly, running his tongue along the length. His grip tightens on the base of Ryusei’s cock while he moans, sending teasing vibrations through Ryusei’s body.
“Fuck, fuck, fuck, Sae, I’m so close, please don’t stop.” Ryusei pants, his body shivering and Sae doesn’t miss how his arms tremble as Ryusei is trying to behave.
He smiles around Ryusei’s cock in satisfaction, then picks up the pace, sucking harder while jerking him off simultaneously, focused on pushing him over the edge quickly.
He doesn’t have to wait long until Ryusei cries out in warning. “’M so close, gonna cum, gonna- ahh shit!” A strangled moan tears from Ryusei as he comes into Sae’s mouth, his whole body shaking with the force of it.
Sae does his best to swallow but it is too much and since he has never done this before, he ends up choking. He pulls back, coughing and spitting, gasping for air while cum mixed with saliva trails down his chin, dropping onto his thighs.
Ryusei slumps to the floor next to him, trying to catch his breath, looking utterly blissed.
“It was… fucking great, Lashes.” He pants hoarsely, his grin huge but somehow softer than usual.
Sae wipes his mouth to hide his pleased smile, then gives Ryusei a nonchalant look before standing up and turning away. “Make sure to clean up the mess.” He orders and before Ryusei could utter a word of protest, he retreats to his own room, locking the door.
Sae sits on his bed and jerks off hurriedly, his strokes quick and erratic as he tries to reach release as soon as possible. He is already way too worked up, so it only takes a few minutes before he covers his mouth and comes spilling into his hand, shaking in ecstasy. He falls back on the bed, trying to catch his breath.
Shit, this was… well, what was it?
The answer will arrive rather soon: A goddamn disaster.
It happens again. And again. And again. Sae has lost count of how many times he sucked Shidou off, as he somehow made it his mission to catch him in the most unexpected moments. Not that Shidou minded.
Surprisingly he only complaines a handful of times about Sae not letting him to touch, but he still respects Sae’s boundaries and never does it. It is as if he fears that touching Sae would ruin everything and if Sae were to be honest, he fears that too. Letting Ryusei touch him would make things too real, well realer than they already are. It is stupid, Sae knows in the back of his mind, but still clings to it like a lifeline. He isn’t sure what this is, but it is fun and he doesn’t want to mess it up by putting a label on it.
Fooling around has gotten to the point where Sae decides it is time to step up his game and he pushes Ryusei down the couch on one Monday morning, shrugging his bathrobe off and climbing on top of him completely naked.
He almost chuckles at the way Ryusei’s eyes widened when realization dawns on him. Sae pulls Ryusei’s boxers off in one swift motion and isn’t surprise to see his cock already half hard, a rather nice compliment to Sae’s ego.
“Sae-chan?” Ryusei asks unsurely but with a hungry stare.
Sae only spares him a glance before grabbing the lube he previously hid behind the cushions and ignores Ryusei’s comment of “not just handsome but smart, I’m so lucky” and how it causes his heart to skip a beat. Instead, he pours liquid onto his fingers and starts stretching himself, that does shut Ryusei up.
He hisses at the cold feeling penetrating his insides but grits his teeth and endures. Thank god he has practiced beforehand or this would be much more awkward. Still, he is determined not to let his inexperience show and by the look of Ryusei, he does not give a flying fuck about such details.
Again, that sense of satisfaction washes Sae over as Ryusei stares at him in awe with mouth agape, devouring Sae with his eyes while licking his lips in anticipation. It feels fucking amazing, being wanted that much. Sae makes sure to give Ryusei a good show, throwing his head back a little and biting his lower lip to hold back a moan as he adds a third finger. He is now pushing three fingers in and out of his hole, trying to stretch himself as best as he can.
“Fuck, Sae, you’re killing me.” Ryusei whines, his hands grabbing the armrest so hard it creaks. He still refrains from reaching out.
Sae has to admit Ryusei’s self-control is rather admirable, a stark contrast to his obnoxious, stubborn personality. It makes Sae wonder if he is an exception. Ryusei has never listened to anyone, yet he almost always listens to Sae. Sae can’t figure it out so he just keeps ignoring it, like he does right now in favor of focusing on the more pressing matters.
“Patience, demon.” Sae grunts softly, making a few more stretching motions before pulling his fingers out and pouring more lube onto his palm. He grabs Ryusei’s erection and coats it with his strokes, making it slick as he jerks him off with a few firm, steady moves.
Sae did his homework well and he has been preparing for this for a while by now. Poor Ryusei never stood a chance. He is also pretty sure Ryusei has never expected him to actually take things this far, so Sae really got one over him, he notes triumphantly.
He positions himself over Ryusei’s lap, lifting himself and guiding Ryusei’s cock to his entrance, taking a deep breath.
Ryusei’s eyes widen. “Shit, are we gonna do it raw?”
Sae tilts his head a bit and raises an eyebrow. “Is that a problem?”
He knows they are both clean, since they get checked regularly and Ryusei boasted about it last time, claiming he is more than ready to give Sae a healthy baby or two, to which Sae responded by shutting the door into his face. He is also rather curious how it would feel to be filled up, but there is no way in the nine hells he would admit that.
Ryusei nearly chokes on his saliva.
“No, no, please continue, whatever you want, darling.”
The smallest smirk plays over Sae’s features but before Ryusei can comment on it he presses the tip of his cock inside.
“Ahh, fuck!” Ryusei cries out, holding onto the armrest for dear life as his whole body tenses in pleasant anticipation.
Sae closes his eyes, and grits his teeth, trying not to make a sound while he struggles to get his breathing under control. He slowly works himself down on Ryusei’s thick cock, the smallest grunts escaping his lips.
Ryusei is big, it is no surprise. His erection stretches Sae further uncomfortably, and no matter how much he has prepared, it just couldn’t compare to the real thing.
“Need some help, angel?” Ryusei offers with a grin, but the strain in his tone betrays his smug expression.
“’M fine, just give me a moment.” Sae grunts as he maneuvers his body on top of Ryusei, trying to find a good angle.
It takes him a bit of time to get used to the feeling but with a few more pushes he manages to take all of Ryusei, tearing a strangled moan from the man under him.
Sae opens his eyes at last, pleased with how wrecked Ryusei looks, the veins almost popping on his arms as he is still gripping the armrest. Deciding he teased him enough, and also wanting to get things moving, Sae braces himself on Ryusei’s chest and rolls his hips experimentally.
“Ugh, Sae, you fucking tease.”
“You’re so impatient.” Sae points out just a little out of breath as he lifts his hips.
“Mmmm, that’s because- fuck!” Ryusei can’t finish as Sae sits down, the feeling knocking the wind out of Ryusei. He could barely believe this isn’t a pipe dream, the one and only Sae Itoshi on top of him.
Sae feels a pleasant, tingling sensation spreading through his body as he starts riding Ryusei, setting a steady rhythm. He is trying to keep his voice down as best as possible but some moans still manage to escape, much to Ryusei’s delight.
Soon, the discomfort is replaced by pure pleasure and Sae is getting bolder, trying to find the spot that makes him see stars. He tries different angles and flexes his muscles, pulling more obscene sounds from Ryusei, who soon gets the idea.
He starts thrusting his hips up in time when Sae sits down, finally hitting that certain spot that makes Sae cry out in bliss against his determination to keep quiet. He is starting to get lost in chasing his high, becoming more vocal to Ryusei’s satisfaction.
His cock is leaking with precum, standing for attention painfully hard, but Sae ignores it for now. Ryusei moves his hands from the armrest beside his head, twitching. “Fuck, Sae, please, please, let me touch you, please, I want-”
Sae trembles and nearly breaks, but catches himself in the last second.
“No,” He says sternly and leans forward to hold Ryusei down by his wrists, their foreheads almost touching. His whole body is flooded with a twisted sense of satisfaction as he watches Ryusei going absolutely crazy under his hold, his body shaking as he is trying to obey Sae. Nothing could compare to this power trip and Sae is getting drunk on the sensation. He almost leans forward to kiss him but stops himself. That would sure make things more awkward and complicated.
Instead, he stares into Ryusei’s desire blown eyes and commands in a firm tone “move your hips, demon.”
He is testing Ryusei, they both know that and for a moment Sae thinks he has pushed him over his limit, but then it is gone and Ryusei nods in surrender.
He licks his lips then plants his feet on the couch, making Sae fall forward a bit but getting a better angle, and he starts buckling his hips in time with Sae’s movements. He is setting up a nice rhythm and pushing both of them closer and closer to the edge.
“Ugh, right there.” Sae groans and shuts his eyes tight, Ryusei’s intense gaze becoming too much to handle right now.
His prostate is being hit with more force in this new position and with his erection trapped between their bodies, Sae can feel his orgasm approaching, the sensation starting to make him lightheaded.
He is desperately trying not to embarrass himself by coming too fast but thankfully Ryusei isn’t in a much better shape. It is probably his first time as well, Sae realizes belatedly, the thought making something twist in his chest and warmth spreads around his body.
After a few more well aimed thrusts from Ryusei, Sae reaches his high, biting his lips enough to draw blood to stop himself from crying out pathetically. His orgasm comes crashing down on him, making his vision white and body tense as he spills all over their stomachs without being touched.
Feeling Sae tighten around his dick makes Ryusei come seconds after him with a loud moan, his body going numb and toes curling as he shoots his load into Sae, whose body is shaking as strength is leaving him. Still, he does not collapse on Ryusei, to Ryusei’s disappointment.
He had secretly hoped for a little bit of post-orgasm cuddle, to finally get his hands on Sae’s gorgeous body. Maybe another time. Ryusei is still coming down from cloud nine when Sae pulls off him.
Sae has never been more grateful for his grueling training regime, that gave him almost inhumane stamina. It now helps him to get up and somehow make the short walk to the bathroom without his legs failing him, shutting the door behind him and collapsing to the shower floor.
“Fuck.” He whispers as he lets the hot water run, clumsily cleaning the cum still dripping from his hole.
From then on, riding Ryusei has been added to the weekly tasks of Sae’s to-do list.
