Kakashi watches as Minato prepares to draw the seal, carefully dipping the brush into the pot of special ink, making sure to cast off errant drops before preparing to make the first stroke. Minato must notice the tension in Kakashi’s body, the slight wavering in his resolve, because he pauses just before the brush touches his skin and looks into Kakashi’s face. “Don’t tell me you’re getting cold feet?”

“Of course not,” Kakashi answers, and he wasn’t, not really. Kakashi had gotten his first period last year, and Minato had been concerned that birth control wouldn’t be enough to avoid the risk that comes with having the equipment Kakashi has in the shinobi world. Violence of any kind can and will be used, and it is best to be prepared for worse case scenarios.

The seal Minato was about to apply was supposed to reduce his chance of pregnancy to zero. More efficient than any birth control Kakashi could take, it was obvious that it was his best choice if he wanted to be a competent shinobi. Minato had spent months ensuring its accuracy, fiddling over every aspect of the design until he was certain it would work, and decided that now was the time to apply it.

Kakashi can’t quite understand why he’s so nervous. Perhaps it’s partially because Kakashi is currently naked, Minato insisting on no obstructions while he paints the seal directly over Kakashi’s womb. Minato allowed him a medical mask, but it did little to lift the unease about the fact that he was laying naked on his back in Minato’s living room while Kushina was out with Mikoto for the day.

“Good.” Minato applied the first stroke, his skin tingling under the feel of the cold ink and the slight electric sensation of chakra being pushed into the seal. Every subsequent stroke gives Kakashi goosebumps, his hair standing up straight along his arms as Minato carefully writes each character of his seal. “This is for your own good, you understand.”

“I do.”

The brush stops. The seal is finished. Kakashi doesn’t feel any different, but Minato appears satisfied, so he doesn’t question it. The ink dries, chakra setting, making the seal glow softly before it disappears, invisible unless activated. Kakashi peers at where the characters once were, curious, while Minato begins to put his sealing materials away.

Kakashi took this as the cue that it was safe to get dressed, slowly sliding on his boxers, then his pants. Minato pats his head, ruffling his hair, and he feels a minute heat at the touch. It’s not quite the same sensation he usually feels from physical contact, the strange buzzing when the few people in his life make skin on skin contact with him. It isn’t completely different, however, so Kakashi thinks nothing of it, shaking his head before reaching for his shirt.

The seal seemed like a success, and Kakashi doesn’t think anything of it for a while. It was simply a just in case seal for worst possible scenarios, though Kakashi believed the fear was unfounded. His ability to fight and willingness to kill made enemy capture and torture unlikely. Kakashi had always figured he would kill himself before anything to that degree would happen, a righteous death to prevent state secrets from being revealed. The fact remains that in cases of capture and torture, suicide was encouraged, because rescue operations were rare, and torture was not a matter of if but when the capture would pry the information they wanted from you.

It wasn’t a fear Kakashi had, confident in his abilities to perform the mission or to terminate himself if all goes wrong, but Minato had been fretting ever since Kakashi had bled during a mission. Whatever eased Minato’s conscious was fine with Kakashi; as the hokage, the man had enough on his plate.

For a few weeks, he doesn’t actively notice anything different. Idly, he notices an uptick in the way his eyes will linger on an attractive man or woman longer than usual, but he was at that age where sexual attraction would be developing. Kakashi didn’t exactly have a high libido, so he did notice when he began to feel slightly warmer in the presence of those that were aesthetically appealing, but again thought nothing of it. He was still in control of himself, and teenage hormones were nothing to worry about, even if he found them mildly humiliating.

A month passes and Kakashi finds his gaze doing more than lingering, roaming the figures of those around him. The people he watches aren’t objectively beautiful anymore; his gaze lingers on even his Anbu comrades, many of whom he had never even seen their face before. But the strength of their bodies, the tight coiled muscles, the power in their frames, and of course the wonderful assets a well sculpted body can provide in the areas of chest, ass, and thighs, provided a strange temptation in the back of his mind, a pooling heat building in his gut.

It was subtle, the rise in his sexuality, the awareness of the bodies and people around him, the attractive qualities in the people he fought beside. Soon, even the people he fought against were not immune to Kakashi’s gaze, eyes wandering over whatever their armor revealed, strong arms that pinned him down, powerful thighs tight around his abdomen, a slight bulge with unarmored targets that fought back.

His interest in women began to scale back, and the more he was surrounded by men, the more the heat built within his groin. Kakashi had never thought of himself as particularly sexual, but as the weeks pass, he’s noticing more and more thoughts regarding the people around him, the sensuality of their bodies, and a lingering interest in the bulges of the tight pants many of his comrades sport.

Casually, Kakashi began to wonder what it would feel like, to see one of those bulges revealed as a thick cock. What would it feel like to take one of his comrade’s cocks? In his cunt, feeling the head of it breach his tight, dripping heat, the sensation of being filled to the brim as they push deeper and deeper inside him, brushing against his walls, pushing all the way to the hilt, and the feeling of his comrades orgasm, the pulsing hard cock finally releasing itself inside him, spilling their seed into his pussy… Kakashi wondered, too, at the taste of his comrade’s sex, the weight of it in his mouth, the feel of his tongue sliding against a girth cock, teasing a protruding vein, and the taste of his seed as he orgasms, forcing Kakashi to drink every drop of his essence.

Kakashi masturbates for the first time to these thoughts, trying to finger himself, imagining a thick, hard cock breaching his cunt instead of his meager fingers. He isn’t able to get himself off despite how much he tries, brushing against his g-spot and pinching his clit so tight he sees stars. Kakashi goes to sleep that night restless and dripping, dreaming of his comrades pinning him in the locker room or the shower and using his cunt for what it was made for.

The dreams and thoughts aren’t alarming, a slow trickle Kakashi barely realized was there until soon enough, all he could think about was the men surrounding him. He fantasized about getting dicked down on missions, a reward for their success, or a form of stress relief between the handsome men he was often assigned with. He dreamed of being split on more than one cock, pussy stretched wide and gaping to fit the massive girth of more than one men inside, while his mouth suckled sweetly on another’s, sated by having his holes filled.

The worst of all, Kakashi notes idly, is how he had begun to fantasize about Minato as well. Even he wasn’t safe from the teenage lust Kakashi feels overwhelmed with, despite the fact that Kakashi had never been interested in him before. He had always considered the man more of a brother figure to him and had internally excluded him from being attractive, but now Kakashi couldn’t deny the heady pull he was feeling towards the man, his cunt wet any time Minato even looks at him.

Days where he acts as Minato’s guard are the worst. Heat burns through his entire body as he watches Minato go about his day, his tight uniform show casing a not so modest package that has Kakashi salivating under his mask. He’s half afraid his fellow comrades can smell the stretch of his arousal, and half hoping they do so they can fuck him when they’re relieved from his shift.

There’s one meeting Minato had where he asks Kakashi to hide under his desk. The daimyo of the Land of Crystal had been very specific about no Anbu being around, so Minato had dismissed all but Kakashi, sealing the underneath of his desk so the daimyo wouldn’t notice him. Apparently the man was a pretty good sensor, or had a good sensor ninja with him to make sure his wish was kept. Kakashi stopped paying attention when Minato had asked him to sit under his desk.

Kakashi is eye level with Minato’s groin the entire meeting, sitting politely on his knees as he half pays attention to what the daimyo and Minato were talking about. He licks his lips every half minute, imagining the taste of his cock. It was so large from this perspective Kakashi was half certain he would choke on the length of it, his gag reflex fucked out of him by the time Minato was done using his throat.

And that day is when the content of Kakashi’s fantasies began to shift, watching Minato scoot towards the edge of his seat, thinking about Minato fucking him against the hokage’s desk, forcing load after load of his cum into his womb, breeding him like the bitch he was. The shift was subtle, a desire to feel himself full of Minato’s essence, a desire to be so stuffed his seed spills down the lips of his cunt, down the tender skin of his thighs. Kakashi would leave the room with cum dripping down his legs and everyone would be able to see how Minato had used him, that Kakashi had fulfilled his purpose, that his cunt had been thoroughly bred.

Minato had dismissed him after the meeting was over with, and Kakashi had furiously masturbated for hours at the thought of Minato pushing him against his desk and fucking his cunt hard and fast, round after round of orgasms filling his cunt, pushing past his cervix and forcing his seed directly into his womb. Kakashi had finally managed an orgasm with that thought, drenching his sheets as he dreamed of Minato’s hot cum getting him pregnant. The thought of being swollen with a baby, his small tits growing fatter as his stomach grew rounder had him masturbating again, fucking his cunt with his fingers while his other hand pinched at his nipples, imagining Minato drinking from his fat tits, pleasing him, offering everything he can from his body for Minato to use at his discretion.

Kakashi manages to hit another climax, squirting at the idea of Minato fucking him while he’s pregnant, stuffing him over and over again, satisfying his increased hormonal arousal and promising to put another baby in him as soon as this one popped out. The thoughts continued into his dreams, fantasizing of having babies latches to his chest, suckling his milk while Minato feed his greedy pussy to get him pregnant again and again.

Kakashi was constantly burning with heat at that revelation, the desire to get fucked clouding his mind until it was the only thought he had. His mission performance began to suffer, Kakashi wrapped up in the idea of his enemy forcing him on his hands and knees and fucking him hard and fast, threatening to put a baby in him like the bitch he was. Kakashi still killed all of his targets, still performed adequately enough that his missions were a success, but his teammates had begun to notice his distraction. His captain had scolded him for denying the fight so much, which Kakashi had done because he wanted to see if he could tease his target into trying to rape him, but his other teammates didn’t seem as bothered.

In the communal showers, Kakashi is cornered by two of the men he had gone on the mission with. Gecko and Sparrow close in like predators stalking their prey until Sparrow forces him against the wall, pinning him tight just before he could turn on the shower.

“We saw what you were doing today,” Gecko cooed, sliding against Kakashi. He was shifted away from the wall and pinned between the two men, Gecko capturing his wrists while Sparrow spread his legs. Kakashi was already wet from the mission, from spending so much time around these men, and Sparrow had a grin on his face as he investigated his cunt, spreading the fat lips apart and watching his arousal drip.

“He’s already wet,” Sparrow says with a laugh. “You’re a real fucking slut, aren’t you?”

“You really are a hound, aren't you?” Gecko croons, pinning his wrists with one hand while the other gripes at his tit, nipples already hard from the arousal building from the men manhandling him. “Stupid bitch that needs to get fucked.”

“Only thinking with your pussy,” Sparrow continues, pushing his fingers inside, making Kakashi whine. Feeling something inside him has his skin crawling with pure desire, but it isn’t want he wants. He needs his cock, the man’s pants already missing so Kakashi can see his massive asset without being hindered by his pants. His cock was already hard, red and shiny with pre-cum, probably aroused since he noticed Kakashi taunting the enemy target. Kakashi licked his lips at the sight of the pearls of cum, his cunt clenching hard at the thought of being stuffed full with his seed, and Sparrow laughs cruelly. “You’re so tight! But you’re such a stupid mutt, there’s no way you’re a virgin.”

“Fuck me already,” Kakashi complains, unable to handle the teasing. He’s so turned on he’s dizzy, heat overwhelming his brain. He should be rational, he should be reporting these men for sexual harassment, but he can feel the hard cock of Gecko press against his ass and fog settles across his brain as he grinds against him.

“Eager. Should we reward a begging dog, though?”

“He’s being a good boy, right?” Gecko murmurs, breath hot against his neck. “Let’s give the bitch what he needs.”

They fuck him, cruel and rough and mean. Kakashi is stretched out on both of their cocks by the end of the session, pain and pleasure destroying his ability to form any coherent thoughts as they bounce him on their thick, leaking cocks. Gecko groped him, pinching his nipples and kneading at the fat of his small tits while Sparrow leaves bruises on his hips from how hard he grips his waist as he slams into him, using him like he was just a hole, just a toy, and the thought makes his cunt gush with arousal, clenching against the two cocks inside him.

He relishes the feeling of them spilling their seed into his cunt, finding his own climax at the feeling of it dripping down his thighs, his tight cunt milking them for all they have. The men laugh at him, call him names and Kakashi couldn’t care less, finally satisfied by the feeling. They leave him weak kneed and boneless on the ground, cum dripping from his abused pussy, and for a few blissful minutes Kakashi’s ravenous heat had been satisfied, feeling the cum in his pussy, having been bred like he’d been fantastizing about.

The bliss fades. Kakashi finds it isn’t enough.

By the end of the month, Kakashi has fucked almost all of the Anbu members he has ever worked with, and a few he hasn’t. Rumors spread about Kakashi’s easy legs and quite a few sometimes push him against a wall in the Anbu building and fuck him then and there. Kakashi relishes those moments of being used, of being seen as nothing but a toy to be played with, but ever since that first incident of getting fucked Kakashi hasn’t had any luck in orgasming. Most don’t bother playing with his clit or caring about his g-spot, but even when they do, or when Kakashi masturbates alone thinking about what just happened or fantasizing about what will happen, he still can’t bring himself over that peak.

Kakashi is being driven crazy by the simmering heat in his gut. The breaking point is when he successfully entices a target to rape him, pretending to cry and whine as the man forced him onto his stomach and fucked his pussy with his massive cock. Of course, Kakashi killed the man immediately afterwards, but had a sudden moment of clarity that this heat was interfering with his ability to perform missions.

Of course, when he gets back to the Anbu building, the concern is fucked out of him by two more comrades. Instead, Kakashi focuses on trying to sate the burning heat inside him. Getting fucked by his comrades isn’t working, and getting fucked by his enemies isn’t, either. Kakashi is craving something specific, then, but he can’t quite figure out what it is.

Minato invited him for dinner one night, while Kushina is on a mission, and Kakashi suddenly understands. He’s craving Minato. Minato manhandles him onto the couch to stop him from helping him with dinner, the desire to be useful met with Minato’s insistence for him to relax, and Kakashi is over come with arousal from Minato’s touch, from the feel of him forcing him to sit and be good, that he can feel a wet spot form on his boxers, nearly dizzy with desire.

The entire meal is spent with Kakashi trying hard not to either launch himself at the man or stick his hand down his pants to masturbate. Every touch of Minato’s firm hand, on his shoulder, his head, and once at the small of his back, sent heat scorching down his spine and his cunt clenching with the need to be filled with Minato’s thick cock.

But Minato was married, in a loving relationship with Kushina. Kakashi couldn’t fool around with him like the other Anbu.

His body didn’t care about the logic. His cunt wanted his cock inside him, and Kakashi seemed to be a slave to his instincts now. He tries his best to fight off the desire, knowing that his fantasizing was slipping into him trying to make it a reality, but his resolve is weakened every time he interacts with Minato.

He does his best to make himself enticing, bending over to pick up things Minato might have dropped and carefully masking sure his ass was bent towards the man. Wearing clothing so tight you could see the outline of his fat pussy and his hard nipples. Kakashi brushes against him, desperate for his touch, once successfully causing Minato’s hand to brush against his small tit, making him shiver with desire.

Kakashi needed him so bad he was so close to throwing himself at the man. He would do anything to feel his fat cock fuck his cervix, anything to feel him fill up his womb with his seed, anything to have the man bend him over and breed him.

The heat crescendos, crescendos, crescendos until Kakashi can’t control himself anymore.

Kakashi is in his office, reporting for a mission. The words enter one ear and leave out the other, Kakashi absorbing nothing of what Minato was telling him. Minato had Kakashi stand at the side of his desk, Minato scooted to face him, legs spread, cock pressing against his clothes, and that was the only thing Kakashi could think about, his thick, girthy cock fucking him so hard and fast Kakashi forgot his own name.

“You’re not listening,” Minato notes, and Kakashi snaps to attention.

“I am, sir.”

“I’ve been hearing interesting rumors, lately,” Minato continues as if he hadn’t spoken. “They say Konoha’s Anbu Hound has became the Anbu’s bitch.”

Kakashi swallows.

“A few comrades complained about your efficiency on the field. They’re worried you’re compromised. I have my suspicions they might be right.”

“Yondaime, I-“

The hard edge to Minato’s next command has him silenced in an instance. “On your knees.”

Kakashi drops to his knees without thought, pussy drooling from the command and the submissive position. Minato rises, appearing a cross between unsurprised and disappointed, making Kakashi want to whine. He wanted to please Minato, not disappoint him. He leers above Kakashi, his crotch nearly level with Kakashi’s face, and it’s taking all of his strength not to rub his face against his cock, nuzzling and scenting the bulge like a mindless bitch in heat.

“You’re dripping wet,” Minato points out, extending a leg to push the toe of his sandal against Kakashi’s crotch. Heat shoots across his body at the humiliating sensation and from his sensei touching him, making the damp spot on his pants only damper as his pussy leaks. “Look at you, reduced to nothing but a whore because you can’t control your base instincts. This is why I gave you that seal- I was worried about this exact scenario. You wouldn’t be able to control yourself, and you’d fuck anything that moves.”

“I’m sorry,” Kakashi cries, his brain feeling like mush in the face of Minato’s disappointment and the burning heat of his throbbing cunt. “I don’t want to be a whore.”

“Oh?” Minato asks, the toe of his sandal digging into his pussy, rubbing against his clit. Kakashi whines, humping back against his foot, aware of how empty he felt, his cunt desperate to have Minato inside him.

“I want you,” Kakashi confesses, fear and elation at finally telling the truth warring within him. Minato slowly removes his foot away from him, making Kakashi whine, missing the friction, begging for Minato to touch him, anywhere, anyway he likes. His thighs are quivering as he peers up at Minato, his mind foggy with a burning lust coursing through his body, spreading his legs slightly to try to entice him. “Please, sensei, I don’t want the Anbu fucking me, I don’t want them, they can’t satisfy me, I want you, I need you. Please, fuck me, bred me, use me. I need you, sensei, I need you so bad.”

Kakashi babbles, stupid with lust, trying to convey just how desperate he was for Minato. He needs him, the only man who can satisfy his aching, empty hole, and he would do anything to convince Minato to help him.

The hand on his head surprises him. Kakashi looks up through teary lashes, Minato meeting his gaze. His lips are turned into a cruel smile.

“Good boy,” Minato coos, running his fingers through his hair, petting him like a dog, and Kakashi sinks into the touch, nails scratching his scalp. “You finally figured it out, didn’t you?”

“Hm…?”

“A bitch belongs to its master.” His grip in his hair suddenly tightened, forcing his head back. Kakashi moaned, the minor pain mingling with his arousal until Minato let go of him, circling around him for a moment before settling behind him. “Take off your clothes.”

Kakashi obeys without question, glad to be rid of the suffocating material. He tosses away his Anbu gear without a care in the world, nearly ripping his shirt as he tries to yank it off of him. Kakashi's pants and boxers are next, shame unknown in the face of even the slightest bit of relief against the sweltering heat that slithers across his entire body. Kakashi is naked as the day he was born, and even his lacking mask doesn’t bother him like it should, still settled on his knees, politely waiting for Minato’s next order.

“On your hands and knees.”

Kakashi submits, leaning over on his arms, shifting his legs and spreading them slightly to show off his dripping cunt, arching his back to make his ass enticing. His breasts brush against the floor, hard and sensitive, and Kakashi can’t help the breathy whimper that escapes his throat as he presents himself to Minato.

“Good boy,” Minato praises, making his cunt clench, arousal slithering down his spine. “Presenting like a good little bitch. You’re just begging to be bred, aren't you?”

“Yes!” Kakashi cries, cunt pulsing at the idea of Minato doing just that. “Please, please, fill me with your cum, knock me up, breed me, fuck my cervix, fill my womb, please sensei! I need you, please!”

“So polite,” Minato murmurs. He hears the rustling of fabric, resisting the urge to turn around, to move, because Minato hasn’t told him to yet. He stays still, panting quietly, so aroused his body feels flush with a fever as he waits, thighs quivering with need. “Maybe your master should reward you. You just can’t help yourself, being a stupid bitch obsessed with getting rid of that empty feeling, isn’t that right?”

Minato shifts onto his knees, crowding behind Kakashi. His hand rests on his ass before kneading at the flesh, Kakashi whining at the sensation. Something long and hard pressed against his ass and Kakashi mindlessly grinds back against him, desperate for him to slip it inside, to fill him, to use him.

“Yes,” Kakashi whimpers. “I’m so empty, please, make it stop.”

“I should have known this would happen,” Minato says with a sigh. “I thought you could change, I thought you could handle being a shinobi, being an Anbu, but you just can’t help your nature. Oh Kakashi, you poor thing, born a whore yet trying so hard to be something you're not. Have you given up pretending? Aren’t you ready to stop being a shinobi and embrace what you really are?”

The words slide through his brain like molasses. They don’t properly register, but Kakashi can’t bring himself to care. He’d do anything for Minato, agree with anything he says, do whatever he tells him. It’s a response born from the years they spent together with Minato as his commander, and highlighted by his time as Minato’s personal Anbu guard, responding to every command, every wish, every desire, every whim.

“Yes,” Kakashi replies, willing to agree with anything Minato says. His mission performance had been waning lately, hadn’t it? Maybe he wasn’t meant to be a shinobi. The thought should hurt, the thought should at least sting, to know that his goal in life had been shattered, but it didn’t. The thought slipped away as Minato grinds against his ass, and Kakashi can only think of his new purpose, being a good breeding toy for Minato. Being used, having his womb stuffed full of Minato’s fertile seed, waddling around Konoha fat with pregnancy after pregnancy. “Yes, yes, yes.”

“Good boy,” Minato praises. “Why don’t we make good use of you? It’s time I give you what you want, what you need.”

The head of his cock pressed against the lips of his pussy. Kakashi is incoherent, breathy moans as Minato slides the length of his cock against his dripping pussy, grinding against him, rubbing against his lips, coating himself in Kakashi’s arousal. The heat is melting his brain, feeling the object of his desires so close to breaching him, breeding him, fucking him and using him just the way he’s been dreaming of.

“It’s time I breed your fat cunt,” Minato states. “I’m going to knock you up with so many kids, your pussy is always going to be full of my seed. You’re going to be my personal breeding toy, addicted to my cock and only my cock. No one else can satisfy you, and you wouldn’t want them to. The only thing you want is me.”

His cock presses against his hole, flared tip teasing his empty, empty cunt. Kakashi whines helplessly, arousal building with every word, so strong he’s half convinced he might just cum from Minato’s words before he even gets filled. Kakashi spreads his legs, trying to further entice Minato, and this time it does the trick, because Minato finally pushes inside.

He forces it in, fast and without care, bottoming out swiftly, filling Kakashi all the way to the hilt in one fluid motion. Kakashi lurches from the force of his thrust, his cock rutting against his g-spot, and that moment of bliss was enough to make Kakashi teeter over the edge, cumming from the feeling of Minato penetrating him, of finally filling his empty pussy. His cunt clenched tightly, making Minato moan, music to Kakashi’s ears.

“That’s right,” Minato coos, squeezing his hips. “Like a good bitch, you only cum from being penetrated. You don’t need to touch your clit anymore. You’ll feel better when I’m breeding you.”

Minato pulls back once Kakashi’s completely limp, experiencing the bliss of his first orgasm in months. Minato thrusts back inside, focusing on Kakashi’s sweet spot, and the overstimulation makes Kakashi whine before Minato sets an unforgiving pace, fast and rough as he pushes in and out of his pussy, still so tight despite the orgasm, despite the months of fucking other shinobi.

Any coherent thought disappears. Breathy moans are punched out of him as Minato pounds his pussy, pushing deeper, harder, faster with each thrust. He swears he feels the tip of his cock kiss his cervix, making him melt from the realization Minato was going to fulfill his promise, was going to stuff him full of his fertile seed. Kakashi wriggled with excitement at the thought, rolling his hips back to meet Minato’s cock, eager to feel him spill his cum deep inside his pussy.

“Minato-sensei,” Kakashi whines, the syllables barely enunciated, slurred as he was overwhelmed with the pleasure.

Minato doesn’t even break his stride when he slaps Kakashi’s ass, the sting making Kakashi keen, the pain turning him on but the punishment confusing him. He whimpers slightly as Minato kneads at the flesh he had just spanked, not sure what he did wrong. “You’re a pathetic bitch, aren’t you, Kakashi?”

“Y-Yes.”

“I’m not you’re teacher anymore.” His dick brushes against his g-spot, making Kakashi whine. “I’m your master. Isn’t that right?”

Of course. In Kakashi’s hazy mind, it makes perfect sense. Every dog has a master, even heat addled mutts like him. Who else could satisfy him but his master, who trains him, who owns him?

“Yes!”

Minato spanks him again, unimpressed. Kakashi yips, Minato’s hit was hard, a harsh reminder of what he was just taught, a clear warning to try again. “Yes, master!”

Minato strikes his g-spot with lethal accuracy, making Kakashi’s eyes water with tears as Minato fucks the spot hard and fast. “Good boy, Kakashi. You’re a fast learner.”

Kakashi trembles from the force of Minato’s thrusting, hips snapping fast and hard. Minato’s hands were bruising his hips, painful and grounding as he continued to pound his pussy, molding the shape of his walls to his cock. Kakashi’s arms had given up supporting him and he was practically laying on the ground, hips and ass held up only by Minato’s firm grip.

He couldn’t think beyond the sensation of being bred, drooling from the stimulation and the promise of having his womb filled. Whimpers and mewls were the only sounds Kakashi could make anymore, too fucked out to even call Minato’s name, barely cognizant of where he was. At this rate, Minato could fuck him so hard he would forget his own name and Kakashi couldn’t care less.

He can feel Minato getting close to the edge, his methodical pounding becoming messier, more frantic. Kakashi groaned at the feeling of Minato loosing his composure, pleased at the idea that he had caused this, that he had given his master so much pleasure his collected facade finally fell. Minato fucked as deep into him as he could, promising to fuck his womb, making sure Kakashi would be pregnant from this coupling.

“Look at you,” Minato murmurs, pressing his body against his. One hand reaches around to tug on Kakashi’s tit, pulling on his nipple. Kakashi mewls at the rough treatment, arousal threatening to peak as Minato roughly fondles his small tit, tweaking his hard nubs, pleasure and pain bursting across his body. “Finally fulfilling the role you were born for, being a good little breeding bitch. Aren’t you excited for me to knock you up, make your stomach swell with my children, your breasts swollen with sweet milk, your greedy pussy bred? Aren't you excited to be a cute little breeding toy, waddling around, constantly gravid with my children?”

Kakashi’s cunt clenched hard at the idea, pregnant with Minato’s children, kept round and sated with his cum constantly stuffing his greedy pussy. Minato breeding him, making him useful, fulfilling his purpose of being a bitch, submitting to him. His breasts twitch at the idea of growing, full of milk for Minato or his babies, attached to his teats while Minato fucks another load into him, breeding his pussy, whenever, wherever he desires.

“Yes, master!” Kakashi whines, so turned on from thinking about the future he can barely speak.

The new title sends Minato over the edge, spilling his cum deep into his pussy. Kakashi cums from the feeling of being bitched, whining pathetically as Minato fucks them both through their orgasm, cock rutting against his sensative spot as they reach their climax almost in synch. Kakashi’s entire body tensed as hot pleasure sweeps across his entire nervous system, toes curling, cunt vice like against the cock inside him, milking him for every drop, desperate for his seed to catch.

Finally, Kakashi goes completely limp, whimpering from overstimulation until Minato slows down, both of them settled in the sweet bliss of the aftermath of an intense orgasm. Minato stays inside him for a few moments, no longer moving, just filling him, keeping him from being empty, and Kakashi feels light headed, knowing that he’s finally been used by his master, just the way he was meant to be.

Minato removes his cock, sliding out of his pussy with a lewd, wet noise. Kakashi whines at the loss and the feeling of Minato’s cum slowly dripping down his puffy lips, staining his thighs. Minato doesn’t give him too much time to worry, rolling Kakashi on to his back so Kakashi could peer up at Minato, eyes taking in his satisfied smile before locking on to his cock, pulled out of his unbuckled pants, still wet with their arousal.

Instinctively, despite just having been fucked within an inch of his life, Kakashi spreads his legs, eager to have Minato back inside him. Minato grabs his thighs, kneading the tender flesh as he pushes himself between them, letting his cock rest on top of Kakashi’s womb. Minato slides his hands down to his groin, then near his cock, pressing against the spot where he had applied the seal all those months ago, using a small amount of chakra to make the seal appear. The delicate characters and aesthetic swirls appear, making Minato smile.

“I told you I was going to breed you,” Minato says. “I hope you didn’t think I meant one load. I’m going to make damn sure you’ll be walking out of this office pregnant.”

“Please,” Kakashi whimpered, feeling the fire in his groin flicker to life at his words. “Please, master, use me.”

“Such a good boy,” Minato coos, hands slithering up his waist, both hands grabbing his small breasts. His thumbs tease his hard nipples, his callouses catching on the sensitive skin, making Kakashi squirm as heat builds and builds within him, pleased that his master is touching him, pleased by the warmth tweaking his nipples provides him. “I’ll take good care of you, Kakashi. You’re such a perfect, sweet pet for me. Don’t worry about a thing.”

Kakashi doesn’t.

(What Minato failed to tell Kakashi, all those months ago, was that he was partially lying about the seal he had given him. It was designed to slowly increase Kakashi’s libido until he couldn’t go a whole day without getting fucked. He had also designed it to plant the seed of Kakashi becoming attracted to him, knowing the idea had never crossed Kakashi’s mind before, and that he needed a little push.

The seal was a contraceptive, however. He knew the boy was going to be driven crazy by the desire to get fucked and bred, and didn’t want anyone to stake a claim that belonged to Minato.

The seal was a contraceptive… for everyone except Minato.

Not that Kakashi cares about those finer details now.)
