The man lets out a groan and cums down Kakashi’s throat, his hand buried in Kakashi’s silver hair. As Kakashi pulls off, he licks his lips quietly before he readjusting his mask.
“You’ve gotten better at this.” He hears the man say as he tucks himself away.
Kakashi stands, wincing at the stiffness in his knees from kneeling on the floor again. “I’ve had a lot of practice.”
The man barks a laugh and hands Kakashi a scroll he’d kept hidden beneath his clothes. “Next time we see each other, you’d better let me fuck that ass of yours.”
“I’m afraid not.” Kakashi smiles easily, taking the scroll and slipping it into his pocket. “It’s off limits.”
The man snorts and leaves without another word, and the smile slips off Kakashi’s lips.
Never did he imagine he would resort to trading intimate favors for information, but he’s learned it’s one of the quickest methods since joining the Akatsuki a few months ago. His heart twists in his chest as he thinks of Itachi and how this could’ve been his fate had Kakashi not intervened.
Instinctively, his mind replays the event of the Uchiha massacre, a mission Kakashi had never imagined himself undertaking. But the grim task that Danzo had assigned Uchiha Itachi was one that Kakashi could not allow to fall upon someone so young. No child that age should be tasked with wiping out his own clan to prevent a coup they had been plotting in secret against the village. Kakashi couldn’t let Itachi’s hands be stained with the blood of his own family. He had debated it back and forth before ultimately reaching a decision, offering to take on the mission himself to at least spare Itachi from a lifetime of guilt and regret.
The mission was executed with precision, aided by a masked man claiming to be Uchiha Madara. Together, they moved through the Uchiha compound like ghosts, leaving behind only the chilling silence of the night. The once lively and proud Uchiha clan then lay still on the ground, victims of a drastic measure taken to prevent a greater tragedy.
For a long moment afterward, he sat quietly on the outskirts of the village, feeling a hollow, crushing weight in his chest. The guilt swept through his stomach until he thought he would throw up.
He didn’t move from his spot until the masked man appeared in front of him and made an unexpected offer: a place in the Akatsuki.
Kakashi remembered learning about this organization from Jiraiya shortly after Rin’s death. Their goal was to bring peace to the shinobi world. With nowhere else to call home and the desire to keep an eye on the Akatsuki to ensure they posed no threat to his village, Kakashi accepted.
When Kakashi returns to the Akatsuki base that afternoon, he finds the masked man waiting for him in his room. His uncovered eye widens momentarily before he catches himself.
“Do you need something?” he asks, his gaze fixed on the orange mask that reveals only a single, piercing eye.
Kakashi’s sharp instincts and Sharingan abilities make him an invaluable addition to the group, but these very traits also spark a nagging suspicion. The masked man, with his own Sharingan and abilities, feels unsettlingly familiar. A part of Kakashi wants to confront him, to confirm if his suspicions are true. Yet, the fear of the truth has kept him silent, leaving the question to linger in his mind.
“Konan told me what you’ve been up to,” the man says, his voice cold yet layered with an emotion Kakashi can’t quite place.
Kakashi feels his heart pick up in his chest as the man approaches him slowly, almost stalking him.
“As long as I get the job done, the means shouldn’t matter, right?” he asks evenly.
“Is that what you think?” The man’s response comes inches from Kakashi’s face, a dangerous proximity that sends a chill down his spine. “You think you can just give yourself away like that?” He chuckles, but it sounds cold to Kakashi’s ears. “I should’ve made it clear, huh? No one else gets to touch you, Kakashi. You belong to me.”
Stunned, Kakashi finds himself momentarily speechless. He’d had his suspicions, but hadn’t expected this man—no, Obito to reveal himself to Kakashi so soon. However, looking back, the man had been careless, or perhaps intentional, about displaying his distinctive Sharingan, even when they were close enough for Kakashi to recognize its unique pattern.
Initially, Kakashi had considered the possibility of the man simply stealing the eye from Obito’s deceased body. But with each encounter, the sense of familiarity grew stronger. The truth became increasingly clear with each moment Kakashi spent in his presence.
There’s no mistaking it now: this man is Uchiha Obito.
Now, Obito is a bare inch away, and his gloved hand slides around Kakashi’s back and along his waistband. Kakashi can’t help but shiver at the light touch.
“Should I show you who you belong to?” Obito asks, working his hand down the back of Kakashi’s pants. He ghosts his finger across Kakashi’s hole and Kakashi sucks in a breath at the touch. No one’s ever touched him there. He’s always been clear that’s off the table for anyone he’s traded information with.
He doesn’t even realize that Obito had tilted up his mask until he feels Obito’s lips against his clothed neck.
“What do you say, Kakashi?” Obito murmurs. “Would you like to give yourself to me?”
Kakashi trembles under the heat of Obito’s mouth on his skin, his legs shaking as Obito taps against his hole.
“Because I would very, very much enjoy showing you how much you would like it,” Obito says, low and so confidently as though he can read Kakashi like an open book.
And it breaks something open inside him, so easily.
“I—I’ve never let anyone touch me there,” Kakashi says shakily, resisting the urge to push back into the touch. He’s never really been interested in that before, but something about having Obito’s gloved fingers teasing at his ass is really doing it for him.
“I know,” Obito replies with a calm certainty. “Otherwise, those men would have met a far more agonizing end,” he adds, his words a soft murmur against Kakashi’s skin. “But now I’m done holding back. I want to taste you, get inside you, hear you scream for me.”
The revelation of what happened to the men from whom he’d gathered information barely registers in Kakashi’s mind. Instead, a tremor shakes his body at the vivid imagery Obito has painted, the image of Obito’s tongue buried in his ass, Obito’s face pressed up against him as he makes those hungry noises against Kakashi’s skin. The amount of promise in his low voice and the sure way Obito is tracing Kakashi’s rim speaks volumes of what he can do to him.
There’s so much he wants to say, so much he wants to ask Obito, but as Obito presses his dry finger against his rim, Kakashi’s mind and ability to think disappears immediately. His body has gone completely weak and pliant and he’s caught in the promise burning in Obito’s gravelly voice.
“Yes,” is all Kakashi manages to say. “Please.”
Obito’s lips curve against his neck and Kakashi drops like a stone as soon as Obito pulls his arm back, looking up at him desperately.
It’s not like Kakashi has never done this, but right now there’s a searing heat coursing through him, leaving him feeling weak and desperate in a way he’s never felt before. There’s something so freeing, so powerfully arousing to give up control. It’s a feeling he’s never allowed himself to indulge in until now. Kakashi knows there’s no one he’d trusted enough to give himself up to like this in the past. But this is Obito. Obito is the only person in the world to whom Kakashi would willingly give everything.
He dissolves so easily when Obito tugs down his mask and leans in to catch his mouth, Kakashi already far softer under him, opening up to let Obito take him over.
“Aren’t you a good boy?” Obito purrs against his lips.
Kakashi makes an embarrassing noise and Obito’s smile sharpens.
“Yes, such a good boy, Kakashi, letting me do whatever I want to you,” Obito continues, his voice dropping steadily. “And you’ll like it, and beg me for more.” He runs a hand through Kakashi’s hair, tugging his head back gently to expose his throat. “Won’t you,” Obito asks silkily.
“Yes,” Kakashi breathes, his need burning away any lingering shame, leaving him desperate to feel Obito against him. It’s like there’s an override switch inside him and Obito clearly knows he’s found it.
“Good,” Obito murmurs appreciatively as he removes Kakashi’s headband and swipes his thumb over Kakashi’s left eye to coax it open, the twin Sharingan locking onto each other.
Kakashi whimpers softly. Obito swiftly undoes his pants with his free hand, not releasing his hold on Kakashi’s hair. He drools a little as Obito pulls his hard cock out, stroking over it lightly. A pearl of precum beads on the tip, milky white. Obito rubs it against his lips and Kakashi whines, licking it off greedily.
Obito sucks in a breath. “Yes,” he hisses. “Let me hear how much you want my cock.”
He pushes the head of his cock past Kakashi’s lips, and he opens obediently, hungrily. He moans loud around it, the weight on his tongue erasing the last of his ability to think. He wraps his tongue around the head, flicks the tip just to see Obito twitch and sucks, trying his best while Obito controls the rhythm. He’s so hard in his pants, the stiff fabric rubbing against his cock but he ignores it, too focused on trying to pull a reaction out of Obito.
The head bumps against the back of his throat and he suppresses the automatic gag, desperate to choke on it. Obito pulls all the way out, holding Kakashi back from chasing him.
“Tell me what you want,” Obito says, a dark hungry gaze focused on Kakashi’s open mouth.
Kakashi pants, unable to string words together, hoping that opening his mouth wider and pleading with his eyes counts.
Obito shakes his head. “Use your words, Kakashi.”
Kakashi’s eyelids flutter at the gentle tone. “Fuck my face,” he chokes out around another swell of need. “Please, Obito.”
Obito groans and yanks on his hair, feeding his cock back into Kakashi’s waiting mouth. He slides back, hitting the back of his throat again and tests it gently. Kakashi relaxes his throat, remembering how to manage this amidst the haze of desire clouding his mind, and Obito pushes all the way in until he’s crushing Kakashi’s nose to his skin.
Kakashi is a mess. He’s drooling and eager and his vision blurs with tears.
Obito swears reverently as Kakashi works him with his tongue and throat in tandem. He wraps his fingers more firmly in Kakashi’s hair, his other hand coming up to trace his lips where Kakashi’s stretched wide around his cock.
“So fucking beautiful,” he rasps, watching him with undeniable want and approval.
Kakashi’s cheeks burn but he’s not sure if it’s embarrassment or just pure arousal. He’s been called beautiful before while he was on his knees, trying to please those men in exchange for information he deemed important, but it’s never affected him the way it does now. In Obito’s low, gravelly voice, Kakashi wants to hear it again and again.
Obito thrusts into Kakashi’s mouth experimentally, and when Kakashi only whines, he starts to fuck his face in earnest. Kakashi’s eyes drop shut and he digs his hands into Obito’s legs, needing to feel more as he lets Obito use and dominate him. Obito’s movements grow faster and shorter with every thrust before he pulls out abruptly. Kakashi tries to chase him but the hand in his hair keeps him in place.
Kakashi tries to scramble his brain back into order, but Obito pulls him up, even more commanding, and tugs him towards his bed. Within seconds, Kakashi finds himself on all fours in the soft mattress with Obito kneeling behind him. He yanks Kakashi’s pants down and pulls his ass open, baring his hole to Obito’s hungry stare.
Kakashi sucks in a breath. He’s never been this exposed before, and the knowledge that it’s Obito behind him only stokes the burning want inside him even higher.
“Aren’t you a treat?” Obito marvels, running the pad of his now bare finger across Kakashi’s hole. “Can’t wait to get you loose and open and begging for me.”
Kakashi chokes on a whine at the first drag of Obito’s tongue across him, clenching automatically. His legs are shaking in seconds as Obito circles his hole, teasing him with pressure but never going further. His fingers dig into Kakashi, keeping him open as Kakashi pants against the sheets, clutches at them desperately. He tries to push back, silently begging for more.
He feels rather than hear Obito hum against his skin before Obito finally gets the tip of his tongue inside him, persistent and demanding and overwhelmingly hot, and Kakashi’s arms give out. He’s never had anything inside him before and Obito’s tongue is hot and wet and talented and Kakashi’s consumed by the need to feel it inside him.
He pushes back against Obito’s face, trying to help and Obito laughs a little. He backs off, leaving Kakashi whining and needy without the constant stimulation.
“Greedy little thing,” Obito says, rubbing a finger over Kakashi’s spit-slick hole.
Kakashi makes a small noise that breaks into a moan when Obito forces his tongue inside him. He’s never thought about this before and now it’s the only thing he can think about, the way Obito pushes deeper into him, saliva running down his skin. He rubs something inside Kakashi that makes him jerk and cry out and Obito does it again, Kakashi twisting helplessly in his firm hold. He is so close to the edge without his cock even being touched and he’s panting and moaning and Obito pulls back. Kakashi whines at him and Obito laughs.
“Don’t worry. I’m done with you yet,” he says.
Kakashi whimpers in response as he feels his pulse quicken in anticipation.
Obito slides his pants down and off his legs before circling his hole with a finger, the digit gliding easily across it. Kakashi whimpers again despite himself, imagining what it would look like buried inside him and he shoves back instinctively.
“Look how tight you are,” Obito murmurs, half to himself. “Took so much to get you open even a little. You’re gonna feel so good around me, aren’t you?”
The noise that Kakashi makes is high pitched and needy and he can’t even feel ashamed of it. He’s never needed anything more than he needs something inside him, right now. Obito presses lightly against his rim, the pad of his finger just barely pushing into Kakashi. The pressure is so tantalizing with what it’s offering but not giving. Kakashi pushes back, hard, and Obito’s finger sinks inside him a little. He and Obito groan at the same time.
“Fuck,” Obito curses, but the fondness in his voice is unmistakable as he speaks, “Who would’ve thought you could be such a needy little slut?”
The words light something up inside Kakashi and he whines, feeling exactly like a slut and in desperate need for more. Obito pulls his finger out and Kakashi starts to protest, Obito slapping his ass in retaliation. He yelps and a second later Obito is feeding a wet finger back into him, stretching his untouched hole around his knuckles. It’s only one finger and still the drag of Obito’s knuckles against his rim teases him with more.
The second finger burns a little but it’s feeding something Kakashi didn’t know he wanted, and he arches his hips up into Obito’s hand. The digits gently stretching him open, working in and out of him and skating across his prostate is nearly too much. Obito wraps his other hand tightly around the base of Kakashi’s cock, choking off another near-orgasm.
“Still not done,” Obito chides him. “Not done seeing you take my fingers so well.”
Kakashi writhes under him and only barely keeps himself from begging for more.
“Imagine how pretty you’d be, split open on my cock, all tight and stretched and needy around me,” Obito says roughly. “I bet you’d feel incredible.”
He pulls his fingers out of Kakashi, leaving him clenching around nothing as he sits back. The head of Obito’s cock drags across his hole and Kakashi sucks in a breath. It feels so big and hot and Obito taps it against his hole a few times.
“Would it even fit?” Obito teasingly muses.
He rubs his cock between Kakashi’s cheeks, the head lightly catching on Kakashi’s loosened rim. Kakashi’s drowning with the need to be filled, to feel something inside him and stuffing him full. He pushes back against Obito’s cock as he rubs it against Kakashi’s hole, and presses it just a little stronger.
“So needy and demanding,” Obito says with a light chuckle, the roughness in his voice making Kakashi shiver. “Shall we try just the tip?”
Kakashi moans softly and digs his fingers into the sheets at the slowly increasing pressure. It keeps increasing and increasing and he’s not sure it’ll fit and he shakes under Obito’s steady hold. Obito hums and pulls back, Kakashi panting with suppressed need and nerves. Spit hits his hole and he jumps, Obito rubbing it into his rim with his cock before pressing against him again.
It burns a little less this time and Kakashi caves and pushes back, choking as the head pops through his tight rim. Obito groans and curses above him, fingertips digging into Kakashi’s hips. Kakashi’s breath is short and he tenses, the burn almost too much and he doesn’t know if he wants to shove back or try to get away from the stretch.
“Shh,” Obito soothes him, stroking down his side. “Try to relax.”
Kakashi tries to slow his breathing, tries to release the tension in his body against the intrusion. It works, slowly, and the burn recedes, leaving mostly need and the teasing edge of pleasure. He wriggles a little, and Obito slides into him a little deeper. His hands hover loosely over Kakashi’s hips as he works further into him, one thick inch at a time, fulfilling some deep and burning hunger Kakashi never knew he had until today.
He moans as Obito finally gets his hips flush against his ass, filling Kakashi finally and bruising his skin under his fingers. The fullness is better than anything Kakashi’s ever felt. He had no idea it would feel this good. He’s completely stuffed, stretched wide and deliriously high on the feeling of Obito so deep inside him.
He whimpers as Obito pulls out of him slowly, the drag against Kakashi’s rim exquisite and tantalizing. The first thrust back in has him gasping for air, and he scrabbles for a better hold on the sheets, Obito’s thick cock hitting every single inch of him so perfectly his vision goes white for a moment.
“Fuck, look at you all stretched and pretty around my cock,” Obito pants, fucking Kakashi slowly and steadily. “You were made to take me, look how much you love it.”
He adjusts the angle of Kakashi’s hips, and Kakashi makes an embarrassing wail of pleasure as Obito brushes against his prostate.
“There we are,” Obito purrs, and continues to fuck Kakashi ruthlessly, hitting his prostate on every movement.
Kakashi is reduced to incoherent begging noises, tears blurring his eyes at the intensity. He can’t do anything but clutch at the sheets and let Obito use him, let Obito fuck his hole open and raw.
“You’re mine, Kakashi,” Obito growls, “Only I get to fuck you like this.”
It’s not a question, it’s a declaration and Kakashi whimpers at the possessive tone. “Yes, please,” he gasps, “yours.”
Obito’s fingers dig into his skin even deeper at Kakashi’s answer and he grinds into Kakashi even harder before he flips him over, Kakashi barely getting onto his back before Obito’s pushing his legs wide and sliding back into him with a deep groan. Kakashi moans wetly, eyes glazed over with pleasure and mouth open on weak panting gasps for more.
“Say it again,” Obito demands, his pace unrelenting no matter how much Kakashi shakes under him
“I’m yours!” Kakashi cries out. “I’m yours, Obito, only yours.”
That’s all Obito needs to hear before he surges down and bites Kakashi’s lip, soothing it with his tongue and then stealing the rest of Kakashi’s breath with a dominating kiss.
Kakashi makes a pathetic, broken noise and clings to Obito’s shoulders, feeling his muscles flex as he fucks every last grain of focus out of Kakashi. Obito doesn’t give him any space at all, claiming his mouth and pulling his hair as he pins Kakashi to the bed with his body.
Kakashi tightens his legs around Obito’s waist and tries to lift himself up to meet Obito’s thrusts, whimpering weakly when Obito’s thrusts grow frantic before he finishes inside him, stilling with a satisfied groan. Being filled and marked and taken like this sends stars sparking through Kakashi’s vision, and he cums with a startled whine, untouched and desperate, clenching down tight around Obito’s thick cock.
He slumps against the sheets seconds later, shaking and lightheaded.
He misses the heat inside him when Obito finally pulls out, even as he pauses to finger his cum back into Kakashi’s hole. Kakashi squirms a little, panting through the extra aftershocks Obito pulls out when he pets him so gently.
“Remember,” Obito murmurs in his ear, all silky threat and dominance and sharp smile, “you belong to me, and only me, Kakashi.”
Kakashi barely suppresses a whimper and nods obediently. Obito makes a low, pleased noise in his chest as he sits back, lowering Kakashi’s legs gently onto the mattress. He lies down next to him and tugs Kakashi until he’s on his side and his back against Obito’s chest.
There will be time for a conversation later, Kakashi tells himself. For now, the warmth radiating off Obito is comfortable as he pulls him closer with an arm around his waist, and Kakashi lets himself bask in it. With Obito wrapped around him, Kakashi’s breathing slows and he falls asleep within seconds.
