If someone had asked Sasuke about his cousin, Shisui, he'd tell them he didn't have much to say.
It's not that he and Shisui didn't get along, they just rarely spent time together. Shisui spent more time with Itachi rather than with him. Sure they would train occasionally, Shisui had a lot to offer in that regard. But the truth of it was, he didn't know his cousin very well.
Sure, he knew the obvious. Shisui was revered in the clan for his abilities. He was kind and charismatic. Got along well with others. And he was Clever.
Very Clever.
Any time Shisui would offer to help Sasuke train, he couldn't say no. Anything that he could pick from his cousin's brain was a welcome gift.
It wasn't easy though, they never had much time. And Shisui didn't go easy on him. If Sasuke could manage to keep up with him then it would almost guarantee more training, another spar, more to be taught the next time his cousin had the time to spare.
Though to say he had any idea what would eventually come out of this training, would be a lie. But somehow it doesn't surprise him.
Shisui offered a time and place as always.
And as always Sasuke showed up.
Their training was intensive and pushed Sasuke to his limit. Afterward, as they gather their things Saauke takes a moment to pull deeply from his canteen. Relishing the cool liquid in his throat before something comes up behind him. He turns quickly to face Shisui as the other backs him into a tree. He tenses, uncertain of his cousin's intentions. His confusion spikes and shorts out as Shisui suddenly sinks to his knees, deftly pulls out his half-hard cock, and swallows him down.
Sasuke's head hits the tree behind him, and he lets out a breath between his teeth. His canteen dropped to the ground forgotten. He looks down to see dark eyes smugly staring back at him as Shisui slowly pulls back off his dick before swirling his tongue against the head. His hand comes up to take his mouth's place and squeezes, as his tongue slides flat down the underside of his cock before sucking one of his balls into his mouth.
Sasuke moans and tips his head back again. He feels his cousin lick and kiss his way back up the shaft before that wet heat engulfs him once again. He winds a hand into Shisui's hair as he bobs his head, lost to the sensation, as Shisui takes all of him and moans.
Sasuke's not gonna last long.
He's panting, legs shaking as he tries not to make too much noise. Shisui is the epitome of pornographic right now. On his knees with Sasukes cock in his mouth, face flushed, and hair a mess.
And Shisui knows exactly what he's doing as they lock eyes and his mouth sinks fully down his cock once again, moans, and swallows around him. Once. twice.
And it's all he needs, he gasps, and moans as he comes hard down Shisui's throat. Shisui pulls off his cock with one last lingering lick to the slit that has Sasuke shuddering. Wipes his mouth with the back of his hand, and tucks Sasuke back into his pants.
Sasuke's grateful for the tree, he isn't sure he'd still be standing without it.
Shisui stands and leans forward. Lips brushing his ear as he says, " You can pay me back for that later." Before gathering his belongings and heading back down the trail toward the village.
Sasuke takes a few moments to catch his breath and confirm that, yes, that did just happen. Before he too gathers his things and heads home.
~~~~~~ ~~~~~~ ~~~~~~
Sasuke can't stop thinking about it. His cousin's lips, his tongue, the way his dark eyes bore into him as he quickly took him apart. Mixed up all the pieces and left him to put himself back together.
He's distracted, he knows. The whole afternoon. Dinner with his family. He knows he shouldn't be this distracted in front of his family.
But he can't.
Stop.
Thinking about it.
And what did Shisui mean when he said he could pay him back later?
When later? What exactly did his cousin want?
He sighs, nervous. It's not that he thinks Shisui will do anything, or want anything problematic from him. But Shisui is crafty. Who knows what he expects of him?
"Sasuke. Are you alright, sweetheart?" his mother asks from beside him.
He pauses his motions, a bowl of rice in one hand, chopsticks poised with his next bite in the other.
He sighed out loud.
He doesn't look at his mother. Just stares at the remnants of his meal.
"Sorry," he says after a moment. "Just tired. Training was a bit demanding today."
"Shisui really put you through it, huh?"
He looked up at Itachi, a small smile and a look in his eyes, as if he could see the day's events as his own, and knew exactly what Sasuke had been through today.
Sasuke lets out a small hollow laugh, more a huff of air. "Yeah. You could say that."
His brother raises an eyebrow and just looks at him for a moment before he returns to his meal.
Sasuke's appetite is ruined. He forces himself to eat most of his dinner before he excuses himself. Desperate to close himself behind doors, take some time to think about everything.
Shisui's cryptic words. His brother's knowing smile.
He stopped outside his bedroom door.
Did Itachi know?
Or was he just sympathizing because he had been through Shisui's more ruthless training methods before?
The two were so close it wouldn't surprise him if Shisui had told his brother what had happened earlier that day.
Sasuke sighs again. He needs to lie down, sleep, and stop thinking so much. He was getting a headache.
He slides open his door, shuts it behind him, and makes for his bed. He barely manages to get undressed before he hits the covers.
A quick struggle with the blankets till he's comfortable.
He closes his eyes and prays sleep comes quickly.
~~~~~~ ~~~~~~ ~~~~~~
When Sasuke wakes it's dark, the only light coming from the moon through his windows
There's a tapping sound coming from behind him. He sits up, and the window opens before he can even think to do so.
"I was wondering if you would wake," Shisui whispers as he climbs through the window. Shutting it softly behind him.
"Shisui? What time is it?" Sasuke asks groggily, surpressing a yawn.
"Early. Don't worry everyone's asleep." He answers as he makes his way over to the bed.
"What-?" He's cut off as Shisui climbs on top of him and covers his mouth with his own. Sasuke's so caught off guard he doesn't do anything when his cousin strokes his jaw to deepen the kiss, slides his tongue against his, and bites his bottom lip. He groans as Shisui tilts his head up to suck a mark into his neck and palms his quickly-growing erection through the blankets. His cousin leans back to quickly pull his shirt over his head before he leans back in.
Sasuke stops him with a hand against his chest. "What are you doing?" he asks, panting. His tired mind trying to catch up with what's happening.
"I told you, you could pay me back later," Shisui says with a smirk, as he hooks his fingers in the blankets and pulls them down. Shisui moves to rid him of the blankets entirely, before crawling back towards him to hook his fingers in the waistband of his underwear. His cousin takes a moment to look at him, really take him in, before he pulls them down and off. Takes no time to take his thighs, pull him down the bed, and spread him wide.
He lets out a startled sound as something warm and wet slides against his rim, he quickly presses a hand against his mouth as he feels more than hears a quiet laugh from the other.
"Quiet now, or you'll wake everyone up." he hums. Before he scrapes his teeth across his hole.
Sasuke's lost in it all, of teeth and tongue licking him open, before wriggling inside. He moans into his fist before grabbing the pillow and pressing his face into it. Shisui's fucking him open with his tongue and it's taking everything he has to not vocalize his appreciation.
A finger presses in with the next plunge of his tongue and starts stroking till it finds his prostate. Sasuke whines into the pillow, gasps, and keens as Shisui abuses that spot inside of him. He's shaking, and he knows it's only a matter of time before he comes.
And then it's gone.
Sasuke lays there for a moment, catching his breath, and listens to the sound of Shisui's movements before he moves the pillow.
Shisui climbs back up the bed to lay next to him, pulling Sasuke to straddle his now bare hips. He reaches between his legs and he can feel the head of Shisui's cock swipe slick against him, and he pushes back against it.
"Fuck, you really want this don't you?" Shisui breathes as Sasuke slowly seats himself, panting.
Sasuke braces himself against Shisui's chest and takes a moment to get used to the feeling, rolling his hips against the hard flesh inside him. Shisui's hands find his hips when he pulls back, and lifts himself off the cock inside him, before plunging back down, knocking the air from his lungs. Shisui's hands quickly urge him back up only to fall back down, and they find themself at an urgent pace, lost in each other, trying to find the pleasure only another can release.
Shisui winds a hand into his hair and pulls him down, claiming his mouth in a bruising kiss. Holding him flush, as he fucks up into him. Sasuke turns his face into his cousin's shoulder to muffle his moans,and lets himself be used. The other biting marks into his flesh. Hands move down to grab at his ass, and another is in his hair, pulling. Has him sitting back as lips press against his neck and a deep voice rumbles in his ear.
"You're being so loud, brother. It's a wonder you haven't woken mother and father yet."
He gasps as the hand leaves his hair and clamps itself around his mouth. Another wanders up his stomach to toy with a nipple. He whimpers into the hand as teeth scrape against his neck, the hand at his nipple leaves and moves lower to tug at his dick. He keens at everything happening. The hard cock inside him, nails digging into his hips and thighs. The hand on his cock, and the mouth sucking and biting marks into his neck.
It's too much.
He's cumming.
His body jerks in its intensity, as he coats his brother's hand and cousin's stomach with his come.
As he finally comes back down he finds himself lax, falling forward into his cousin as he pulls out. They're both panting, and Shisui wraps his arms around him, one hand pushing into his hair as they catch their breath.
He can feel hands on his hips as something hard and thick is pushing into him.
He gasps and writhes, he is so sensitive. His hands fist the sheets as Shisui holds him and shushes him, running his hand through his hair.
He's full again.
So fucking full. It's too much.
He hears Shisui groan. "Fuck. This is so hot."
And Sasuke pushes past the overstimulation to look over his shoulder, to catch his brother's eyes as he pulls out of him just to push back in slowly. The noise Sasuke makes is choked, and he buries his face in his cousin's shoulder once more as his brother slowly fucks him.
He can feel Shisui's come dripping down his thighs as the man whispers praise in his ear. Says to him he's doing so well. Tells him how good he looks stretched around his brother's cock. He can feel Shisui's hand slide down his back to his ass, fingers sliding around Itachi's dick where it enters him.
"You're so wet," he breathes. And Sasuke moans.
There are fingers at his throat and he shudders. They tighten and he's being pulled back till his head meets his brother's shoulder.
Back bowed, he gasps as Itachi thrusts into him hard.
Fingers are tugging at his nipples, as the one at his throat tightens again. He hears Itachi let out a low breathy groan, feeling the breath across his shoulder before it's replaced by teeth.
All Sasuke can do is pant and gasp around the hand at his throat, as his brother keeps up a merciless pace. Fills him again and again. The wet slap of flesh against flesh filling the room.
Shisui shifts beneath him, and hands leave his nipples to run down his stomach. Fingers are dancing across his cock and Shisui's dick slides against his as the fingers tighten.
He whimpers and the hand at his throat tightens again. He's gonna come again, the pleasure building as his brother fucks him just right, every thrust sparking pleasure through his entire being.
He can barely get air in. Shisui twists his hand around the heads of their cocks, and Sasuke shudders. He's right on the edge. Itachi's practically growling as his rhythm grows frantic. Shisui panting beneath him as their cocks slide together and he squeezes.
And Sasuke slips over the edge.
He comes hard and his senses fizzle out with the force of his orgasm.
~~~~~~ ~~~~~~ ~~~~~~
When Shisui wakes it's still early. The barest hint of color returning to the sky.
A sharp intake of breath behind him has him turning over.
And he can't help but stare at the scene before him.
The forms of his cousins barely lit by the new morning sun. Sasuke's knees draped over Itachi's arms as the elder slowly grinds into him. Sasuke's nails have left trails in his brother's back as he gasps at the ceiling.
Shisui trails his hand down and fists his cock. Content to watch the ebb and flow of their coupling.
Shisui groans as his release is building. Wound tighter by every stroke of his hand, every gasp and groan from the two beside him.
Sasuke turns his head and locks eyes with him, gasps, and pants before letting out a shameless moan. Shuddering, as Itachi groans and jerks into him.
Shisui couldn't be happier with how the night's events turned out, as he came over his hand and stomach for the second time that night.
