Work Text:
When Shidou walks back into the locker rooms, it’s just to get the phone he’d left behind. That’s the plan. In and out, so that he can get back to the hotel to get ready for a celebratory dinner tonight with the team.
Reunited with his glittery pink phone, he sends off a quick LINE message to Sae. You should crash dinner with the PXG boys tonight~!!!!
Shidou’s ears perk up at an immediate buzz-buzz of a notification vibration.
Sure enough, his searching eyes spot Sae’s bag, seagull plush keychain hanging off one of the zippers. Come to think of it, he does hear a shower going. Is Sae here, taking one of his infamously long and indulgent showers? Why is he hiding out in the PXG locker room instead of Madrid’s? Curiosity piqued, he pockets his phone. Maybe Shidou can get himself an eyeful while he tries to convince his very sexy friend (and enduring crush) to come to dinner.
He saunters down the hall into the showers, but as soon as he enters the warm, steamy area, he freezes.
Because under the sound of running water is the unmistakable sound of panting, broken up by little grunts and whimpers, underscored by the slap-slap-slap of skin hitting skin.
Shidou’s jaw falls open in shocked delight. Since when is Sae-chan the type to fuck in somewhere as public as this? It’s surprisingly slutty of him. Shidou’s almost proud.
The shower stalls are tall enough to block the view of whoever’s inside, but Shidou has to know.
“Sae-chan?” Shidou calls out, echoing through the tiled space.
The sounds abruptly cease.
“Sae-chaaaan,” Shidou whines, “you wouldn’t ignore your bestest friend in the whole wide world, would you?”
Shidou’s almost to their stall, gauging the jump he’d have to make to peek over the top, when the door opens and Shidou almost falls flat on his face because the man who sticks his face out, the man who’s clearly in the middle of fucking Sae, is…!
“Wrong Itoshi,” Rin snaps. He flicks his dripping bangs out of his face. “What the fuck do you want?”
“Hooooly shit,” Shidou says, instead of answering the question. “So the two of you finally worked it out, huh?”
“What are you talking about?”
“I mean, it sounded like you were showing Sae-chan a good time in there.” He grins. “Well, maybe not good enough, since he could still keep quiet, but…”
The sheer rage that Shidou can put on Rin’s face is so funny every time. “Just leave me alone,” he grits out, and tries to close the door, but Shidou lunges, wedging a sneakered foot in before Rin can get it shut.
Rin wrestles him for the door. “Fucking perv,” Rin hisses at him. He slips a little on the wet tile, and that gives Shidou the leverage to shove the door open just a bit more.
“Just stop,” a third voice orders. Shidou and Rin both obey instantly, Shidou’s own shock mirrored in Rin’s wide eyes.
“Nii-chan,” Rin says helplessly.
“What? There’s no point in risking injury over this. It’s just Ryuusei.” Itoshi Sae pops his head around the door, equally wet, his bangs ungelled and falling across his forehead. “Hello, demon.”
“Holy shit. I guess congratulations are in order, Rin-Rin! You finally got what you wanted!”
“What does that mean?” Rin asks testily.
“It means your little crush on your brother was always so pathetically obvious~”
“Oh, shut up,” Rin starts, but stops short when Sae turns to him, gazing up at him with the warmest, softest expression Shidou’s ever seen him make.
“Really? Rin was obvious?”
Rin’s angry expression mellows into an adorable pout. “Like I could hide it.”
Sae takes Rin’s face in his hands, pressing their very naked bodies against each other. “You love me that much?”
“Obviously,” Rin murmurs. He leans in for a kiss, but Sae tilts his head to the side to evade it.
“Come prove it to me.”
Could anyone blame Shidou for the next words out of his mouth? “Can I watch?”
“Fuck off,” Rin snarls, at the same time Sae says, “Sure, why not.”
Shidou snickers at how fast Rin switches gears to horrified. “Nii-chan!”
“It’s Ryuusei,” Sae says, like that explains everything. Shidou’s little heart might burst if Sae keeps treating him like this: like someone special. He lets go of Rin’s face and walks back into the stall. “Just let him in and get inside me again.”
With an order like that, Shidou doesn’t blame Rin for disappearing back inside the shower without even sparing him another glance.
Shidou strips in seconds, leaving his clothes in a pile on the floor outside and joining them in the shower stall. It’s big, roomy enough that it only feels a little crowded with all three of them, and there’s even a stone bench against the wall. Shidou takes in the Itoshis’ naked bodies, the well-earned lines of muscle moving under their pale skin as Rin takes a seat on the bench and Sae nearly jumps into his lap.
Shidou leans against the wall. His cock aches, and he gives it a reassuring squeeze — he’s been hard since that little display in the doorway— okay, fine, he’s been hard since Rin gave himself away. Just the thought of the two of them fucking could get him off. (Hell, it has gotten him off before.) The knowledge that they actually do? He’ll jerk off to that for months. Years!
And now he gets to watch as they fuck for real? He might pass out from how fast all his blood is rushing to his dick, crack his head on the tiles, and die right here in the shower.
Shidou’s first real treat is the sight of Sae arching his ass up while Rin uses his fingers to nudge his cock inside his cunt. Sae slides down onto his dick slowly and indulgently, letting out a harsh breath when he sits all the way down, spread legs flush with Rin’s hips, and—!
Shidou comes.
He can’t help it. He’s always keyed up after a good match, and the wet dream come to life playing out in front of him of one soaked Itoshi sinking inside another: the sight, the sounds, the inescapable knowledge that they’re brothers holy shit this is so fucked up… It’s just too much.
He lets out a long, loud groan of relief as he shoots straight onto the shower floor, jerking himself off frantically to ride the high of the explosion as long as he can, before collapsing heavily against the wall. “Goddamn.”
When he flutters his eyes open, his cum is swirling gently down the drain, and Rin and Sae are both staring at him in shock.
“That was pathetic,” Rin finally says.
Shidou gives him a lazy grin. “Keep saying stuff like that and I’ll get hard again in no time!”
“Rin,” Sae urges, and Rin’s attention snaps back to his precious older brother.
The two of them start to fuck in earnest, Sae starting up a rhythm in Rin’s lap, bouncing and grinding and swirling his hips. Rin keeps a tight grip on Sae’s waist and thrusts up to meet him, mouthing along his neck. They’re both panting and whining, murmuring praises to each other Shidou can barely hear. And Rin keeps shooting Shidou these glares over Sae’s shoulder, eyes dark and smug, staking his claim with eye contact as he bites his brother’s earlobe.
Shidou barely has to play with his dick to get it back to standing up proudly. The Itoshis make it way too easy.
“Do you like Ryuusei watching?” Sae asks suddenly.
Rin scowls. “What? Fuck no.”
“Really?” Sae’s voice is breathy, the two of them still rolling their bodies together. “Because you keep looking at him.”
Rin tears his eyes away from Shidou’s. “I do not.”
Sae ignores the obvious lie. “Do you want to suck his cock?”
Shidou groans, thumbing the head of his dick. “Don’t tease me like that, Sae-chan…”
The furious refusal that Shidou expects never comes. Instead, Sae answers patiently, “I’m not teasing you, demon. Look at how much he loves it.”
Shidou pushes off from the wall, hand on his dick, to walk forward and get a better look. Sae leans back to reveal the two fingers he’s shoved into Rin’s mouth. Rin’s tongue lolls as Sae plays with it, dipping his fingers deep into the top of Rin’s throat and back. Rin doesn’t gag, and his eyes are hazy, fucked out. Shidou’s dick aches.
“Do you want it?” Sae asks again.
Rin gives the barest nod, a flush across his face.
Shidou doesn’t need to be told twice. As soon as Sae extracts his fingers, Shidou steps as close as he can and juts his hips out. “C’mon, Rin-Rin, open wide.”
Rin turns his head to the side as he does, drool sliding out of the corner of his mouth.
As Shidou pushes his cock into that wet, hot mouth, Sae lets out a contented sigh and reaches down to play with his clit. He starts to move again, taking over as Rin just lies there and takes it. Shidou’s thrusts turn bolder and deeper, and Rin moans, muffled, one hand leaving Sae’s waist to grab Shidou’s hip.
“Isn’t he cute like this?”
Sae’s words make Rin whine, a little shiver going through him.
“Gonna come?” Sae asks Rin, but Shidou’s the one who shoots straight toward the edge at the thought.
“Fuck yeah, come inside your brother, get Sae-chan pregnant!”
Rin’s mouth is so wet, completely dripping with drool. His muffled noises turn desperate as Shidou’s thrusts become erratic, pushing himself closer, closer… And then Shidou tugs his cock free at the last minute and comes all over Rin’s pretty face.
Rin coughs, spitting saliva out onto the tiles. “You stupid cockroach,” he sputters. One of his eyelids is covered in cum — his thick eyelashes are clumped with it.
Shidou puts a hand on Rin’s shoulder and leans down to lick it off. Rin cusses him out but he lets him do it, and Shidou licks his face nice and clean. Well, clean enough for someone who’s literally under the spray of a shower. When Shidou reaches his mouth Rin even slides their tongues together—
Toe-curling pleasure-pain shudders through him as a hand grips his wet and flattened hair by the roots and tugs him off. Sae’s teal eyes are icy as they stare him down. “Who said you could kiss my little brother?”
Shidou just came, but his dick gives a valiant, painful twinge as it endures the wave of arousal that face and that voice instill in him.
“Oh, fuck you.” Rin, who they’d face-fucked adorably stupid not one minute ago, bares his teeth at Sae like an animal. “You’re the one who invited him in here in the first place. You’re the one who offered up my throat. I’ll kiss him if I want.”
“Don’t be a brat,” Sae says cooly.
Something dark flashes in Rin’s eyes. “Who’s a brat?” He lifts Sae off his cock and manhandles him until he’s flipped positions, in Rin’s lap again but with his back to Rin’s chest, both of them facing Shidou. Shidou backs off, leaning against the wall again, wondering if he’s got another orgasm left in him.
Rin shoves his cock back into Sae hard enough to knock a cry out of him. “Since you wanted him to watch so bad, here. He can watch while I finally get off.”
“What about Sae-chan?” Shidou asks as Rin starts up a rough and brutal pace. Sae is helpless in Rin’s grip, just taking it and choking out gasps and aborted moans. Shidou is helpless at the show, mesmerized by the power dynamic flipping on its head; he touches his sore dick and shivers at the oversensitivity.
“What about him?” Rin says carelessly. “He already came like five times.”
Shidou rocks into his fist. “Fuck. Seriously?”
“He tries so hard to be quiet but his cunt gives him away.” Rin’s hand snakes down to Sae’s clit. “It tries to milk me dry. He came when you told me to get him pregnant.” Sae lets out his loudest, dirtiest moan yet.
Shidou groans in answer. “Fuck, he wants it.”
“Rin,” Sae gasps, desperate and hoarse.
“Aah, nii-chan…” And then Rin is clutching Sae close, teeth sinking into his shoulder as he moans his way through his orgasm. Shidou gives himself one last squeeze at the sight of cum dripping out of Sae’s full cunt, and then lets go.
The Itoshis come down together, wrapped up in each other. Rin is peppering kisses along Sae’s temple and murmuring sweet things, and Sae’s arm is raised so he can run his fingers through Rin’s sopping hair. Being a voyeur of such a beautiful sight is nice and all, and Shidou’s had plenty of fun this evening, but he’d be lying if he said he didn’t feel just a little pang of loneliness.
So, he walks up to them, feet slapping against the warm, wet tiles, and bends down to hug them both tight.
Despite his grumbling, Rin is trapped under the both of them and still inside Sae, so he has to sit there and take Shidou’s overly affectionate nuzzling and back rubbing. Best of all, he can’t even do anything except click his tongue when Sae pulls Shidou into a sweet, lazy kiss.
After finally using the shower for its intended purpose and a lot of soft touches, as the three of them get dressed, Shidou can’t help but open his mouth hopefully. “Y’know, if you ever want to do this again…”
The Itoshis have an entire conversation with just their eyes. Then, matching teal gazes flick to him.
“Change your flight. Fly back to Paris on Tuesday instead of tomorrow,” Rin says. “We don’t have practice till Wednesday.”
“Stay the weekend at my place,” Sae says. “That’s what Rin’s doing.”
Well. Plans were made to be ruined, right? Shidou’s a flexible guy~
“You got it, lashes.”
