The air in front of Kakashi swirls and his eyes widen as he stares at the alien figure walking towards him. Despite the strikingly different skin tone and hair color, there is no mistaking that the man now looming over him is Obito. It looks like he’s succeeded, after all.
“Did you wait long, Kakashi?” Obito asks as he grabs Kakashi by the hair, making him look up from where he is still kneeling on the ground. He doesn’t wait for Kakashi’s response and shoves his mask down with his free hand, a hint of a smile playing at the corners of his lips, but something in his expression makes the hairs on Kakashi’s neck stand. “So pretty.”
Kakashi is about to glare at him, but instead his eyes widen in horror when Obito suddenly pushes his pants down, freeing his massive, throbbing cock inches from Kakashi’s face.
“But you’d look even prettier coming apart on my cock.”
Kakashi freezes both at the sight and Obito’s words, feeling his heart stutter in his chest as fear surges through him. The size of the member in front of him is inhuman, terrifyingly so. The tip is already glistening with precum, the smell of his arousal filling Kakashi’s nose. It’s then that he realizes what Obito is planning to do, the reality of the situation sinking in. And the thought of Obito doing that to him, of being taken by Obito in such an intimate and terrifying way, makes his stomach drop.
Kakashi instantly renews his struggles, trying to wrest his hair from Obito’s grip without success.
“Let me go,” Kakashi grits out. He tugs at Obito’s hand and twists to get it out of his hair, but soft, elongated tendrils wrap tightly around his torso and arms, preventing him from struggling any further.
“The war is over, Kakashi. There’s no need for us to be on opposite sides anymore.” Obito finally lets go of his hair as he speaks, the smile never leaving his face. “Now we can be together. Now, I can take care of you like you deserve.”
Kakashi shakes his head, putting more effort into his attempt of getting away from Obito, trashing his limbs against his restraints in a desperate bid for freedom.
Obito’s smile only grows, his eyes glinting with amusement as he leans down. “I guess we’ll have to ease you into it,” he mumbles as his hand slides back into Kakashi’s hair and makes him stare up into those mismatched eyes.
Kakashi’s whole body shudders as the sensation washes over him. It’s like his body instantly melts as his mind begins to panic. Obito releases his hair and Kakashi startles when the tendrils around his body begin to shift. Before he even has a moment to question the reason for their movement, his whole body is violently jerked and rotated, his face landing downwards on the ground with his knees spread and bent underneath him, propping his ass in the air.
The tendrils proceed to crawl into his clothes before ripping it off until only shreds remain. His pants are torn down in one rough motion, exposing his bare ass to the chill air of the void dimension. If there was a doubt in Kakashi’s mind that Obito was really going to fuck him, it vanishes the instant the other man smooths his hand over his newly exposed skin, leaving goosebumps in his wake.
He’s no match for Obito’s strength even in his human form, and like this, Kakashi feels like nothing more than a declawed cat with no way to hide or shield himself from what is to come.
Still, he tries to scramble away, only to be grabbed and dragged back easily by Obito’s tendrils.
“N-No, no, don’t do this, Obito, please—“ Kakashi tries to plead, but Obito shushes him with a soft cooing voice. He jerks in surprise when he feels something stiff and dripping wet prod at his exposed hole. The pliable appendage pokes and prods at him gently as surrounding tendrils grab his waist and hips tightly, refusing him any bit of movement shying away whatsoever.
The familiar stretch takes him back to his nights alone at home, but he promptly catches himself and shakes the thought off.
He clenches instead, attempting to dissuade the intruder to no avail. He feels his rim muscles softening, yielding under the caresses, almost welcoming the tendril. His cheeks flush in mortification as the tendril slicks him up good, licking and sucking at him. The liquid covering the appendage seeps against his entrance, making his hole feels weird and itchy, loosely twitching and clenching for some reason. “W-what did you do?”
“Shh, Relax, Kakashi. Just let it happen,” Obito murmurs from somewhere behind him as he grabs at his hip and holds him steady. Then Kakashi feels a wet, warm and blunt head of what he can only guess is Obito’s cock rubbing against his ass, parting his cheeks and beginning to stretch him open as it rocks back and forth against his quivering entrance. “I’m going to make you feel so good, and you’re going to love every second of it.”
Panic takes over Kakashi’s body once again, leaving his heart slamming against his ribcage from his fright.
He can’t let Obito have his way with him. Not like this.
“No, stop! It won’t fit, please, Obito—“ He claws at the ground, his chest heaving as he struggles anew to twist away once more, but it is all in vain when Obito merely starts pushing into him, inch by excruciating inch. “Ah!” Kakashi cries out. The pain is intense, a white hot bolt that shoots through his body from the large intrusion. Obito’s cock isn’t even entirely in yet, but Kakashi already feels unbearably full. He can’t imagine how it’ll feel when Obito fits the whole thing inside him.
“Stop fighting it, Kakashi. You’re only going to hurt yourself.” Obito huffs out a chuckle as he rocks forward again.
After the initial thrust, his cock begins to push in easier, faster. Kakashi can feel every curve and vein along the heavy shaft as his slicked-up walls let it slide in. He feels his body begin to relax and his hole loosen obediently, walls growing soft to accommodate that monstrously thick length inside him until Obito’s hips press snug against his ass, fully impaling Kakashi around his throbbing flesh.
Completely and absolutely filled beyond what he thought was possible, Kakashi gasps for breath, struggling to take oxygen into his lungs. To his relief, at least, Obito isn’t moving. He lets Kakashi quiver around him, keeping still as if he’s waiting for Kakashi to adjust.
Kakashi tries to catch his breath, but when he looks down, his heart nearly stops. He can see that Obito’s impossibly large cock is now completely inside him, far deeper than any normal human’s length should ever penetrate. His abdomen has a visible swell from the sheer size of it, and every time he sucks in a breath, his stomach tightens around it, making the bump even more apparent.
It makes him sick.
It also stirs up an indescribable sensation he can’t pinpoint.
But Kakashi doesn’t have time to mull over it because his moment of reprieve is short lived. He’s barely allowed two more breaths before Obito’s hips start a slow rhythm, the throbbing hardness of his cock sliding out a few times and slowly pushing back in, as if testing the waters. Kakashi shuts his eyes tightly, inhaling heavily every time Obito’s length drags out, and having his breath punched out with every press inside.
“You feel so good, Kakashi. I knew you would,” Obito muses after a groan at the tightness squeezing his cock, the reverent way he says it making Kakashi’s stomach curl.
He bites back the pained gasps as much as he can, trying to hold back his tears as his body trembles in an effort to stop from falling apart. This time, Obito spares him no mind and begins quickening the pace of his hips as he fucks into him, brushing against his most sensitive spot with every stoke. His cock pulses against Kakashi’s walls, each thrust driving him deeper, carving out a space for himself inside Kakashi. It’s like he has no room left inside his body for air, everything rearranged to accommodate Obito’s enormous length.
Kakashi’s chest heaves as he forces his eyes open, watching the way it moves inside him, a lecherous outline of the monstrous cock sliding within. It’s hot and thick, throbbing and pulsing, dragging across Kakashi’s stretched walls in a way that makes him feel weird, makes his body tremble.
The slick sound of it mixing with the lewd slap of skin against skin echoes within the desolate space as Kakashi is fucked mercilessly without pause.
He closes his eyes and tries to ignore it, tries to disassociate himself from the experience.
It doesn’t work.
As Obito’s thrusting grows more intense, Kakashi starts feeling hot, an itch forming deep inside him and getting stronger every second. His body aches but not in the acutely unpleasant way he knows it should be. It’s quite the opposite. He feels as though his entire body is alight with pleasure, arousal thrumming low in his veins and his hole clenching with the want for more around the unforgiving girth splitting him open. His breath hiccups as the grip on his hips starts dragging him backward, slamming him against Obito’s front to make sure the invading length is sheathed completely inside again and again.
It doesn’t take long before Kakashi feels his body responding positively to the onslaught, his cock swelling despite his best effort to distract himself from the mounting pleasure. He swallows a whimper, squeezing his eyes shut tighter and willing the arousal away.
As if reading his mind, Obito falls into an even more powerful rhythm, faster and harder as he snaps his hips against Kakashi’s ass with fervor, pistoning his cock in and out of his tight hole at a frightening pace. Kakashi gasps and tries to struggle away, but this proves to be just as useless as all his previous attempts. Obito’s hands on his hips are unyielding, and he gives another deep thrust that jostles Kakashi’s whole body, that rubs fiercely against his prostate.
The intense burst of pleasure robs his breath away and Kakashi balls his hands into tight fists, his blush seeping all the way down to his chest as he barely manages to stifle the embarrassing sound that would’ve escaped otherwise.
Sweat is forming on his temple and back as his mouth trembles from the effort to keep his voice under control, but it’s getting more and more difficult when Obito pulls out nearly completely and repeats the motion at a fast, steady pace, hips rocking so fervently against Kakashi that each time he is brought a little closer to the edge.
Kakashi’s attempt to maintain his aggressive front completely crumbles when the tendrils wrapped around his limbs begin to move too, squirming as they seek out his most sensitive areas. They pull at his nipples, squeeze his waist and run up and down the delicate skin of his inner thighs. Their movements are slow and deliberate, a stark contrast to the wild rhythm of Obito’s thrusts, designed to ignite every nerve ending and heightens his sensitivity.
He can’t stop his hands from trembling, his muscles from tensing and twitching against his will with every stroke against his fevered skin and every quick, ruthless thrust taking him apart.
Kakashi can only lie there helplessly and bite down shakily in an attempt to prevent any more unbecoming sounds from escaping past his lips. His breath comes quicker and quicker as shockwaves of pleasure threaten to overtake his senses, each more intense than the last. He’s on the very edge. His cock is throbbing and dripping precum onto the ground, a traitorous betrayal to the fear and anger warring within him.
He doesn’t know how long he is held and used like that, to him it feels like an eternity of Obito molding his insides to the shape of his cock. And then it happens—the intense pleasure ultimately forces the coil in his stomach to snap and Kakashi cums before he can stop himself, completely untouched, white splattering messily between his legs in broken streaks.
The orgasm hits him in waves, his hips spasming and his muscles locking up tight through the entirety of it as his vision darkens around the edges. He distantly feels Obito slam into him and climax with a literal tidal wave of thick, hot seed gushing into his ass.
Kakashi must’ve blacked out because the first thing he sees when he gains his vision back is the small bump of his stomach filled with Obito’s thick fluid. He blinks away the haze in his eyes, before his gaze involuntarily trails downwards to the puddle of his own cum on the ground below him. Kakashi’s breath stops in his throat.
He came.
He came from being fucked by Obito in his monstorus form.
As if sensing his inner turmoil, Obito leans in to drawl in his ear, his voice dropping to a venomous but sickly sweet tone at the same time. “It’s okay. You’re doing so good for me, Kakashi. Such a good boy.”
Obito’s tendrils withdraw and release his limbs, but Kakashi barely registers it. He sucks in a shaky breath, feeling horrified, and refuses to lift his head up. His entire body is still buzzing with the aftershocks of his intense climax, his quivering arms barely holding himself up as he stares at his cum filled belly with the outline of Obito’s massive cock showing, evidently still hard and throbbing inside him.
He lets out a gasp when Obito suddenly wraps an arm around his upper body and hauls him up effortlessly until his back is pressed against Obito’s chest. The gravity causes Obito’s cock to slide further inside him, and Obito grips both of his thighs to spread him apart so that Kakash can clearly see his bulging stomach and his puffy rim clenching around Obito’s monstrous cock. Kakashi shivers at the sight and subconsciously presses down against the hot flesh, craves to feel it deeper inside him.
Behind him, Obito’s low chuckle tickles his ear before he lifts him off and then slams him back over his cock, hitting Kakashi’s prostate on the first try, making red hot pleasure explode inside him. His body is still overly sensitive from his orgasm that the way Obito grips the back of his thighs sends chills down his spine, the other man slowly building up to a pace until Kakashi is constantly bouncing over his cock. His legs dangle uselessly off the ground as Obito lifts him up and impales him on his cock over and over like his own personal cocksleeve. Kakashi’s toes curl tightly and he can barely keep his eyes from rolling back as he’s mercilessly fucked within an inch of his life.
Cum dribbles out the edges of his swollen, abused hole when Obito draws out, thick base no longer stuffing him full, only to be promptly plugged back up when Obito yanks him over his cock again. Obito’s cock slides over and over into his own sticky mess, creating wet, obscene sounds that seem to resonate throughout the vast expanse of their dimension.
Kakashi’s mouth parts in a short gasp, unable to fight against the maddening sensation of the throbbing cock drilling violently into his ass. His mind swirls in a fog of charged arousal, and his treacherous body tells him to beg for more, but Kakashi refuses to give in. He doesn’t want this.
He keeps telling himself that even as his cock springs back to full hardness at a frightening speed under Obito’s ministrations and he whimpers and gasps desperately for air, his skin hot and prickling. Obito isn’t even breaking a sweat, his new form seemingly allowing him endless stamina and strength to keep going, body firm against Kakashi’s quivering one.
As if the sensation of having his sensitive insides stimulated relentlessly isn’t enough, he feels two of Obito’s tendrils trail up his burning skin, causing sparks of pleasure to erupt from the touch. The soft tendrils circle around his nipples, squeezing and pulling to mimic suction. They pinch, pull, press, and rub until Kakashi’s nipples are soft and swollen, no longer a light shade but rather a deep pink from the abuse. His mouth falls open, tongue twitching as the spikes in pleasure sear his brain cells. The need for release swirls around his gut, leaving Kakashi a trembling mess as he fights the buildup, but it proves to be an uphill battle. When Obito’s thrusts suddenly grow frantic, his guts coil in anticipation of being filled with more of Obito’s hot cum. And it only takes a few snaps of his hips before Obito stills with a low groan, unloading another heavy stream of cum into him.
Already pulled taut like a wire waiting to snap, an abrupt orgasm instantly rips through him and Kakashi sees stars, mouth dropping open and back arching as he spills all over himself. His walls clench around the pulsing cock inside of him as the intense pleasure rips through his burning veins.
He didn’t think it was possible, but he feels like the bump of his stomach just grew bigger. He can feel each pump of Obito’s cock as the liquid heat filling him coats his insides. Obito rolls his hips lazily, fucking his cum further into him. Kakashi’s hand finds its way to his now slightly rounded stomach, marveling at the amount of cum he is able to hold within him. His other hand holds a shaky and loose grip on Obito’s arm, holding onto it as his still erect cock twitches at the sensation.
“That’s it. Give in to me, Kakashi,” Obito rumbles softly, voice low and smooth, crushed velvet in his ears as he watches Kakashi’s face contort from the mind-numbing pleasure. “Just let me take care of you. I’m going to give you everything you need.”
Kakashi doesn’t even realize Obito has stopped moving. He only becomes aware of this fact when the other man reassumes his unforgiving pace, using the cum that was pumped into him as an extra lubrication at this point. Kakashi’s cock is still hard, curved up towards his stomach, flushed a deep red and aching with arousal. He can feel precum pulse out from the slit every time Obito fucks inside.
His eyes start to roll backwards again as Obito continues working him to a crescendo of pleasure that threatens to shatter his resolve. He’s close. He’s already close again, and it’s too much, too fast, but it feels so good to be so full, to be taken, and used however Obito likes. His enormous girth is consistently brushing over his prostate, sending sharp jolts up his spine and making Kakashi cry out in pleasure.
“There we go. Let yourself feel it, Kakashi.” Obito hums, darkly triumphant, but his voice is soft like a caress. Kakashi wants to lean into it.
Obito slows down his hips into more gentle rolls and less aggressive strokes, giving himself respite while still stimulating Kakashi’s most sensitive spot on every inward push.
“All that struggle for what, hm? You’ve gotten better at hiding it, but I told you, I know you so well, Kakashi. Your mind is cluttered with useless thoughts and bottled up emotions. I’m here to free you from that. You don’t have to worry about anything anymore. Let me take care of you.”
Kakashi can’t hold back any longer, unable to argue with the truth in Obito’s words. His tears spill in streams and his mouth tremble, helpless to stop the sobs that wrench out past his lips. He has lost and he knows it.
At the end of the day, this man is still Obito, and Kakashi could never bring himself to resent him even if he wanted to. Obito is the one who cracked Kakashi open to the light and has been the reason for him to keep fighting for a long time, persistently pushing forward even when he thought the world was hell and he wanted nothing more than to follow him to the Pure Land.
He’s lived the better part of his life with Obito in mind. The one thing he seeks above all else for the last two decades is Obito’s approval. Such is the depth of his devotion. He’s become an intrinsic part of Kakashi’s existence, and as it turns out, even the revelation of Obito being the man behind the mask wasn’t enough to erase that. His mind and body belong to Obito, completely and utterly.
He no longer has the will to fight, his senses beginning to succumb to Obito’s promise of salvation and the tremendous never-ending pleasure he’s drowning in.
No more pain, no more grief, no more nights plagued by nightmares. Obito will take care of him.
It sounds tempting—too tempting.
Kakashi sobs. His entire body gives in and his muscles grow slack in Obito’s grasp, the other man’s grip and warm chest against Kakashi’s back a grounding anchor amidst the torrent of emotions flooding his frazzled senses. Being this physically close to Obito feels like a balm to his weary soul, soothing the aches and pains that have accumulated over the years.
Kakahi inhales sharply as Obito picks up his speed and ravages him in the same merciless pace from before, fucking him back into a spiralling frenzy of pleasure. Everything burns, fire igniting in his gut as the flames flicker up into his chest and down his limbs. The sensation is electrifying, and Kakashi surrenders himself to the staggering amount of ecstasy coursing through his thrumming veins.
His stomach spasms erratically, his sloppy hole clenching around the thick cock driving in and out of him as the stimulation of the rough thrusts drags him to the heights of another climax. He throws his head back with a broken moan as a stream of hot liquid practically shoots out into the air in thick spurts. White noise fills his ears, pleasure wracking through his body in pulses.
The orgasm heightens his sensitivity even more, saliva pooling in his mouth and dripping out the corners as a litany of moans breaks free from his throat. Obito doesn’t even slow down through his release, continues to fuck his brains out in that inhuman pace, stretching it out until Kakashi is crying and shaking, gasping for breath as the high of his orgasm begins to fade. Every inch of his body feels oversensitive and tender, but Obito evidently has no interest in showing him mercy.
Kakashi whimpers helplessly and squirms in Obito’s tight grip as each ruthless thrust into his prostate pumps more and more cum out of him. Obito keeps up his brutal pace until he lets out a low growl and Kakashi feels warmth flood his insides, his abdomen growing increasingly full from all the cum he has in him.
Kakashi trembles as he catches his breath, his head falling back against Obito’s shoulder.
Obito sighs, deep and satisfied. “That wasn’t so bad, was it?” He lets out a light chuckle as he presses a kiss to Kakashi’s shoulder.
Kakashi closes his eyes and shivers when Obito traces a blazing path from his navel up the taut plane of his abdomen, his fingertips following the obscene bulge caused by his own cock. The intense climax leaves Kakashi a limp, trembling mess, but the monstrous cock in him is still hard and throbbing, and Kakashi knows Obito is far from finished with him.
He wants it to be over.
He wants it to never end.
His mind is a whirlwind of conflicting thoughts, but his grip on reality has loosened significantly and along with it is his control over his body. He’s exhausted after three consecutive orgasms in such quick succession and his vision is blurry with tears, but he wiggles as much as his spent body allows to get Obito to move, to thrust into him again.
“More, please,” he whimpers, voice barely recognizable as he grinds down desperately. “Obito, more, ah, m-more.”
More touch, more pressure, more pleasure.
He wants more.
A moment later, Kakashi is empty, and he can feel Obito’s cum seeping out of him in thick globs, his muscles clenching around thin air as Obito pulls him off his cock. He almost sobs with how much he wants him back, his terror long gone, replaced by the intense desire to feel Obito’s cock deep inside of him and stuffing him with more thick cum.
Suddenly, Kakashi finds himself splayed on the ground and Obito is above him, his dark eyes roving over Kakashi’s panting form—the redness of his cheeks, the trembling of his spread legs, the drool leaking down his chin, the tears brimming in his eyes. He must look like a mess, but Obito is looking at him like he’s anything but.
A hand rests on his cheek, and Kakashi instinctively flinches. Yet the hand is now gentle, merely wiping away his tears.
“You look so beautiful when you cry.” Obito’s lips curl up into a smile and he slams him back over his cock without further warning, barely giving Kakashi the time to adjust.
Kakashi bites his lip to stifle a moan, flushing from the sound of his own pathetic noises as he takes every inch. His hole is already so accustomed to Obito’s monstrous girth that it only takes a few hearty thrusts to spear him all the way through.
“Stop holding back. I want to hear you, Kakashi,” Obito says softly as he begins to pound into him again, slow and deep and full, bringing a whole new flavor of ecstasy. The feeling is exquisite, a mingling of the physical and emotional closeness surrounding them. Kakashi feels as if a part of his soul has returned to him, filling a void that he’d long since resigned of being left empty. “Go on, make more of those beautiful sounds for me.”
Kakashi’s jaw instantly falls open. There’s not a single ounce of resistance left in him as he lets out shuddering and inhibited moans befitting a whore, but he is beyond caring, clenching around Obito with a desperation born from decades of longing. The world around them seems to dissolve into a haze of sensation and Kakashi’s head feels so wonderfully quiet in a way he’s never felt in so, so long. All he can think of, all he feels and knows is Obito, his thick cock splitting him apart, and the sparks of molten pleasure sent to his brain from that throbbing cock drilling deep inside him.
Obito lets out a groan with another roll of his hips, leaning down to kiss Kakashi’s neck and murmur right in his ear, “See? It feels good, doesn’t it?” Obito’s voice is tinged with pleasure. “Don’t you just want to be stuffed with cock every waking moment, Kakashi?”
Kakashi can’t help the way his stomach tightens with desperate need. Obito’s words... they’re doing something to his brain. Kakashi can’t think straight. He can hardly process the noises he is making anymore. At this point he is delirious with lust, and all he can think of is how much he wishes to be made to cum on Obito’s cock and to be filled to the brim and then some. Over and over and over, for as long as time will allow.
His body is opening up so easily, weak to the pleasure he’s come to learn and experience. Each thrust Obito delivers to his prostate sends an electrifying shiver through his entire body and all the way down to his toes, intensifying his pleasure and drowning out everything else. It has his cock steadily dribbling and his toes curling, no longer feeling any pain, just steady, ruthless pleasure.
Obito shifts his grip onto the back of Kakashi’s thighs and hike them up until Kakashi’s legs are dangling over his shoulders, his pliant body almost folded in half beneath Obito as he rams in with full force, using his weight to cage Kakashi in their isolated space away from the rest of the world.
Kakashi can barely breathe. Tears blur his vision as the blissful pressure builds in his lower belly. It coils tighter and tighter and Obito thrusts harder, drives himself down even more forcefully into Kakashi’s shaking body. One of Obito’s tendril slips between Kakashi’s parted lips and Kakashi’s eyes fly open in shock, before rolling to the back of his head as the tendril starts fucking steadily in out of his throat, stuffing him full with the same, burning solidity as Obito’s cock in his ass.
The pace is getting faster and faster and Kakashi’s eyes begin to glaze over. He can barely breathe around the thick appendage ramming into his throat, but he still laps his tongue along the underside desperately like he would a cock. It feels so good to be fucked on both ends; each thrust into his swollen prostate sends spikes of pleasure up his spine, and each thrust down his throat steals his breath in the best way possible.
His fingers stretch, reaching to clamp onto something—anything—to brace himself against amidst the immense sensation. Obito mercifully grabs his hands and guides them to his back before adjusting his position. Kakashi sobs around the tendril in his mouth as Obito continues pounding into him with powerful strokes, clinging to him desperately like Obito is his only lifeline, and in hindsight, he might as well be.
The pleasure builds, a scorching heat that consumes him from within. Every nerve ending in his body seems to crackle with electricity, every inch of his skin ablaze with pleasure. He can feel his orgasm approaching, drawing closer like a tidal wave ready to crash over him. His cock is completely hard, throbbing and drooling pathetically all over his stomach, making a wet mess, and he almost whines when Obito withdraws his tendril from his throat.
But he doesn’t even have time to gulp in a breath as Obito grasps his face and smashes their lips together in a searing kiss. He licks into Kakashi’s mouth, sliding his tongue against his, hungrily tasting as much of him as he can. Kakashi weakly tries to reciprocate through the blurry haze of delirium, but Obito is unrelenting, seemingly trying to devour him whole as he continues hammering into Kakashi with ruthless ferocity. He’s dizzy from the lack of air, but at this moment Kakashi would choose the taste of Obito’s mouth over breathing anyway.
When Obito finally breaks the kiss many minutes later, Kakashi is panting heavily, stray dribbles of drool dripping down his chin. Obito doesn’t waste a second. He lowers his head, burying his face in Kakashi’s neck to leave open-mouthed kisses there, lips and tongue and teeth against his skin. He stays there for a few more moments, relishing in Kakashi’s cries of pleasure, before he moves down and takes one of Kakashi’s oversensitive nipples in his mouth.
Kakashi gaps and mewls, his back automatically arching off the ground as he clutches Obito’s back and presses his chest against Obito’s mouth for more. And Obito indulges him, latches onto the nipple, sucking, swirling his tongue around it. He drags his hand up Kakashi’s abdomen and pinches the other, flicking his thumb over it before rolling the puffy nub between his fingertips, sending a dizzying tide of exquisite pleasure up Kakashi’s spine.
Kakashi’s protesting whine morphs into a chocked out moan when Obito straightens only to resume fucking into him with the harsh snaps of his hips. He feels his cum filled belly and hard cock jostled with the force at which Obito spears into him. Maybe it is in his head, but Kakashi thinks he just heard the load of cum sloshing around inside him. If he was in any other state of mind, Kakashi would be horrified, but he is not. He can’t remember any sense of shame he’s supposed to have. It all feels so good, nothing else matters, and Kakashi—
Kakashi loves it. He loves it, the feeling of being full, of being held and taken so deeply he can almost feel Obito in his throat.
He is crying out and begging for more, tears pouring profusely down his cheeks as he moves his hips to meet Obito’s relentless thrusts with the last remains of his strength. Kakashi has grown absolutely delirious with pleasure, drunk off of it.
More, give more. Want more.
The words ring over and over in his head. It doesn’t stop even as Kakashi feels his vision crossing and he is pushed into possibly the hardest orgasm he’s ever had. His legs shake uncontrollably, squeezing against the body between them, as he bucks and convulses under Obito’s weight from the sheer force of it. It lasts for what feels like a lifetime, the waves of pleasure continuing far longer than any he’d experienced tonight. His insides clench around Obito almost rhythmically, causing the massive girth to press harder against his swollen prostate, milking him to the very last drop and more.
Obito doesn’t let up even as Kakashi’s thighs jerk and his muscles contract from overstimulation. If anything, he begins thrusting into him harder and faster, chasing his own release. Kakashi writhes in place, too weak to resist, practically lifeleses as a rag doll as Obito fucks him at a pace too fast for Kakashi to handle. Every thrust forces a breathless cry out of him. His voice is practically gone from how loud he’s been but he can’t control it, can’t even try to muffle his own sobs as they get punches from his lungs.
The sensation is overwhelming, a mix of pain and pleasure that leaves him shaking, and yet Kakashi can’t bring himself to really want it to stop. Obito is watching him with unabashed hunger, reveling in the sight of Kakashi trembling from head to toe and his broken whimpers as he maintains his vicious pace, slamming into him and nailing his sensitive prostate with every fuck inside, clearly determined to wring every ounce of pleasure out of Kakashi as he can. Kakashi hiccups on a moan and clutches Obito close, legs tightening around him as he claws down his back in desperation.
“That’s it. So good for me, Kakashi. So beautiful.”
Kakashi’s mouth gapes open, but his head is utterly blank, his mind too far gone to string any thought together whatsoever. He barely registers the pleasure Obito’s cock brings him each time it drags across his prostate, until the relentless force of Obito’s thrusts brings him back to hardness even as he teethers on the verge of passing out.
His mouth feels empty without Obito’s tongue and the tendril fucking his mouth, and saliva dribbles uncontrollably from his swollen lips. He feels heat build up fast in his stomach, tightening with every ferocious snap of Obito’s hips. It sends him spiraling higher and higher as he shakes in Obito’s hold until the pleasure ultimately builds to a peak. His lashes flutter, struggling to stay open, and his unfocused eyes roll upwards.
Another orgasm sweeps through Kakashi, his body shaking violently with the intensity of it and his cock spurting out what little it has left, weeping pathetically as Obito fucks into him one final time, thrusting so deep that it knocks the last shred of air from his lungs. Kakashi’s body spasms and shudders, unable to suck in a breath as he feels hot ropes of cum splash into him, pumping him full and heavy.
It leaks out of him when Obito slowly slips out, still holding him up by his thighs. He gently places Kakashi’s lower body on the ground and presses into his stomach with a free hand. Kakashi vaguely feels a gush of the thick fluid spill out of him at a faster speed, his stomach shrinking back to its normal size. He clenches instinctively, a quiet whimper dying in his throat at the sudden feeling of emptiness. But he absolutely has no brain capacity left to voice his protest, unable to slur anything out even if he tried.
Obito shushes him, soothingly soft as he moves so he can lift Kakashi from under his arms. He maneuvers Kakashi’s still trembling body into his lap and cradles him in his arms, pushing Kakashi’s face into his neck as he kisses his hair. The gesture is so tender and affectionate, a counterpoint to the brutal, animalistic way he’d just fucked Kakashi mere moments ago.
“Rest, Kakashi,” Obito murmurs softly. He caresses Kakashi’s knuckles with his thumb before Kakashi feels his warm lips press a kiss to the back of his hand. “We have all the time in the world to make up for lost time.”
And that’s the last thing Kakashi remembers before his eyelids slip shut and he succumbs to the welcoming embrace of darkness.
