Kakashi moved towards the bed slowly. Naruto laid upon it, sprawled out over the sheets in nothing but his boxers. It was a hot night, too hot to wear pants or shirt. The small boy was curled on his side, arms thrown out in front of him. The lower leg was strait while the upper was bent tight to his chest, exposing his pert ass and tail to his teacher’s eyes.
His teacher and temporary roommate moved further into the room; closing the window and the blinds as he passed, before moving to sit on the bed. He didn’t have to worry about being quiet. Naruto had had sleeping problems for the last week, so he slipped something into his tea. Kid would be out for hours, with the dose he was given, he would be lucky to come around when his alarm clock was due to go off.
Pulling his gloves off, Kakashi stroked the blonde hair, tugging gently on the fox ears before stroking the exposed back. A purr rumbled from the hanyou and Kakashi chuckled lightly as he shifted to see better. His hand halted before he gently grabbed the tail and stroked down the fur. He could see Naruto’s cute little mouth part slightly as he let out a low moan. His hips shifted a little as well.
Kakashi raised an eyebrow before he removed his headband. He wanted to record tonight with his Sharingan eye, he was sure it would be a night to remember. Moving his hand to the base of the tail, Kakashi pulled the tail up and found something interesting. The tail ended where the butt crack began; making it so the boxers were pushed low on his hips. Well, that just wouldn’t due.
Standing now, he grabbed the offending garment and threw it on the floor before resuming his previous position. Once more grabbing the base of the tail, Kakashi let his fingers trail along where the tail connected with pert little butt, fingers dipping just barely into the crevice. Another ragged moan was pulled from the luscious lips that his teacher daydreamed about. He imagined them around his cock, fingers fisting in blonde hair as he forced the Jinchuriki to take more of him. And then he would paint that pretty face with his cum and make him wear it out in public so everyone knew what a whore he was, and who he belonged too. Just thinking about it made him hard. Kid wouldn’t even have to kneel, he was so small. Kakashi knew that he was short enough that he would be able to comfortably stand while sucking him off nice and slow.
Shifting to relieve pressure on his aching dick, Kakashi watched fascinated as he applied more and more pressure until he was rubbing the same spot. Naruto’s smaller cock was slowly hardening, and his teacher wet his lips in anticipation. Dipping his fingers further into the crack, Kakashi used his other hand to pull his sweat pants down far enough to expose his swelling cock.
He felt his fingers brush across the child’s entrance, and watched as Naruto thrusted his little hips in reaction. Groaning now, Kakashi dipped the tip of his finger into the inviting hole and moaned as it clenched around his digit. “You’re going to be such a tight fuck, little Naruto. Can’t wait to bury my huge cock into you. Gonna fuck you so hard, that you will feel it for days even with Kyuubi.”
Kakashi continued to play with the rose bud while his other hand came up and separated the pert cheeks so he could get his first look at him. He groaned at the sight. Grabbing the lube, he coated several fingers before he returned to his task. Spreading the delectable cheeks, Kakashi pushed his middle finger in as far as it could go. Naruto’s reaction had him leaking precum onto the sheets. The little kid fucking moaned like a whore and pushed back.
“Fuck,” Kakashi panted, thrusting his finger in and out, fucking the kid’s rose bud with it. “Wish you could see yourself, such a fucking slut.” He added a second and then a third soon after, spreading him open while he watched the little hole consume his fingers over and over again. Naruto himself was hard and leaking, just waiting to be taken, even if he was completely unconscious.
That’s what had to turn Kakashi on the most. He was going to fuck his student, a child of 11 years, and the kid would be fucking sleeping the whole time. Not only that but Naruto lived with him. Chuckling darkly, Kakashi leaned so that he could whisper in his ear. “That’s right, little Naruto. I’m gonna fuck you little ass every fucking night, and you will never know. I’m gonna cum in you so much that it will be leaking out of you for days and I’m just going to keep filling your little ass up every single time you fall asleep. Gonna breed you like a bitch, maybe even let my dogs take a turn.”
Moaning harshly, Kakashi removed his fingers that he had been steadily fucking the boy with and grabbed the lube, smearing it all over his cock. An interesting thing about the Hatake clan that until now he had been ashamed of was his dick. The Hatake’s had always been well endowed, Kakashi himself pushing eleven inches in length and three inches thick. The other thing was they had a knot at the base of their cock, making it so not only did they tie themselves to who they were breeding, but when they cummed, it lasted for a dozen or so minutes, literally spilling buckets of it at a time. They also had a great recovery rate.
When he had been younger, Kakashi had wanted to test how much he could come, and after a series of experiments, he had once jizzed nearly an entire pint, and that was just from spewing once. Taking a hold of his dick, Kakashi moved so he was straddling the strait leg, pushing the bent one further into the little boy’s chest. His sensei spread his ass cheeks again and smiled as the now loose hole contacted like a mouth, begging to be filled.
Pressing the head of his cock to the rose bud, Kakashi moaned loudly as he dipped the head in before pulling out. He did this several times, watching as Naruto’s ass seemed to squeeze harder every time around him, and the little boy moaned softly. Sharingan still active, Kakashi finally forced the entire head in past the tight ring of muscle before pushing slowly in. “Fuck,” he mumbled as he forced his way deeper into the tiny body. He could feel the kid tear a little, and then heal instantly, getting tighter every time. “Nngh, so fucking tight, that’s it little Naru, open up for me. Take my dick, boy, ungh, you fucking slut.”
It seemed to take an eternity before he bottomed out; balls nestled against the child’s lily ass cheek. Kakashi continued to spread the boy open so he could see as he pulled slowly back, watching as the hole squeezed so enticingly as his dick pulled out, and then he pushed just as slowly back in. “Ahh, ahh, yeah, shit. So fucking good. Nngh, that’s it boy, take your teacher’s cock. Know you want it, ungh, ahh, ahh. Fuck.”
He thrusted faster, refusing to close his eyes so he wouldn’t miss a thing. Naruto’s face was pinched and his lips still parted, but he was moaning. “Like that, you little slut? Like being my cum dump, want to take my monster dick every night?”
Kakashi’s eyes moved to the kid’s much smaller cock and he gazed in wonder at the boy’s stomach. He could see the seal, but that wasn’t what he was looking at. Moving the one hand that wasn’t spreading the boy open, Kakashi set it on his stomach and moaned as his theory was proved correct. He could fucking see his dick. “Fuck, Naruto. Ahh, nngh. Wish you could, ahh, see this. Ungh, yeah, ahh, ahh. Your so, nngh, fucking small and, uhg, thin that, ahh, I can feel my cock against your stomach.” And he could. Hand pressed against stomach, Kakashi could feel his cock under the surface, thrusting in and out of the boy’s passage.
The sight turned him on more than he had ever been before and Kakashi moaned harshly as he sped up. Slap, slap, slap, louder and louder. He was thrusting in and out so hard that Naruto was bouncing away from him, before recoil forced him back, making him go that much deeper. “Fuck yeah, you little whore. Fucking take my cock, nngh. Take it, ahh, like the little fucking slut you are. Ungh, nngh, yeah, shit. You like my monster cock, nngh, pounding into your, ahh, tight little ass. Don’t you, uhg, ahh, you fucking cum slut.”
He could feel the base of his cock swelling, now the size of a soft ball, and Kakashi halted his desperate thrusts. Pulling out, Kakashi turned so he was lying behind the still sleeping child. Pinching his cock head, the Jounin spread the cheeks once again and forced his cock back into the swollen gaping hole, ramming all eleven inches and then some as deep as he could. Reaching around, Kakashi placed his hand back over the seal, the new position making it so that his cock made a larger indention. He kept his hand there for several minutes, just feeling his cock moving in and out of the sleeping child.
“Nngh, fuck yeah, gonna fill you up.” Kakashi reached down and worked a finger in alongside his cock, stretching him even more. “Gonna, ahh, knot you like a bitch. Cum, nngh, in you so much you look, ungh, like you’re carrying my pups.” Naruto continued to sleep on; unaware of what his teacher was doing to him.
Kakashi kept pushing, thrusting hard enough to leave bruises, and if Naruto didn’t have the Kyuubi, he would have worried about breaking him. Lifting the bent leg, Kakashi pulled it back and placed it over his hips so he could get even deeper. The little boy’s ass started to yield to the pressure and Kakashi soon had almost half of the knot breaching the hole again and again as he continued to fuck the small child brutally. “That’s it, take it all, ungh, you fucking cock whore. Nngh, ahh, ahh, open up for your teacher. Gonna breed you so good.” Seconds later, Kakashi could hear the pop as his knot was buried into the tight velvet heat.
Several shallow thrusts later and a loud moan filled the air as Kakashi started to cum into the child. His spunk coated the walls, going deep into the passage, filling and expanding it there was so much. “That’s it, you little cum dump. Take all of your teacher’s cum. Gonna stay buried in you all night long, maybe even fuck you a couple more times.”
Kakashi just continued to climax into the unsuspecting and unknowing child for nearly twenty more minutes, before he passed out, cock still buried deep in the child’s ass. He came too hours later, achingly hard and hips already thrusting shallowly. He had been fucking the boy nice and slow in his sleep, the knot making it so he couldn’t pull out that far. He climaxed again a while later, still tied.
When morning came, Kakashi awoke long before the drugs started to wear off of little Naruto and fucked him once more before he moved to get ready for the day. When he pulled out, Kakashi watched fascinated as only a little of his cum leaked along the crevice before the boy’s little rose bud contracted and then returned almost instantly back to normal size, sealing the rest of Kakashi’s sperm inside. Though once again tight, little Naruto’s little fuck hole was puckered and swollen from the long brutal fucking. Stroking it softly, Kakashi hoped it stayed that way as he pushed what little cum that had escaped back in.
Moving so his cock could dip it into the still open mouth, Kakashi nudged it between the rosy lips and moaned in appreciation when the boy started to automatically suck. “Fuck yeah,” he murmured hand cupping the back of the child’s head, gripping his hair and forcing it up and down his length. “That’s it little Naru, just like that. Suck my cock like the cock whore you are. Take it down your throat. Fuck, nngh, if I knew you would be this good I would have fucking adopted you. Would you have like that, then you would be sucking your daddy’s cock instead of teacher’s.”
He forced more of his cock down his student’s throat while he slept on, suckling the dick in his sleep. “Could have trained you to be my personal little pet, maybe whored you out to friends for money.” Kakashi continued to fuck Naruto’s pliant mouth for several more minutes before he felt his balls tightening and then he exploded. Naruto swallowed reflexively milking his teacher’s aching dick, filling his stomach with Kakashi’s cum for nearly ten whole minutes. Only a small bit escaped and dribbled down his chin. “Fuck yeah, drink it up you little slut. Take all of it, yeah, oh yeah, just like that.”
Several hours later found Kakashi eating breakfast when little Naruto came out into the kitchen. He was still only wearing boxers and had yet to put the henge on so his ears and tail were in full view. Naruto yawned widely, cum still decorating his chin, before waving at him and bidding him a good morning. Kakashi replied in kind, removing his headband and opening his Sharingan when Naruto wasn’t paying attention. He didn’t want to miss this either.
Naruto stood before him, looking in the pantry for food, stomach swollen and distended as he was still completely full of Kakashi’s cum. His sensei felt his dick harden as he smiled nearly dangerously at the child before him. Yes, Kakashi did believe this was a sight he could get used too, the child completely oblivious to the fact that it was Kakashi’s spunk sloshing around inside him, so full that it made him look nearly pregnant. It seemed like this was definitely going to be a nightly thing.
“Orange juice, Naruto?” Kakashi asked holding up a glass. Naruto nodded in thanks, gulping it down quickly. It was a little thicker than he was used too, but that may have been the brand. Kakashi smiled deviously as his student drank the juice that he had giving him. It was only half full of OJ. Just minutes before Naruto came out, Kakashi jerked off and came into his glass, pouring the juice and then stirring it up. He didn’t cum as much since he still needed time to recover, but he would be more than ready for when Naruto drank his medicated tea tonight. “Come on Naruto, go get dressed, we have plans today.”
“Meh, I’m not hungry anyways,” little Naruto had no way of knowing that it was because he was full on his teacher’s cum, from both ends. “I have to go to the bathroom first.”
Kakashi frowned only slightly. “We don’t have time, just hold it.”
Naruto ran off to do as he asked and Kakashi felt a sick sense of excitement and arousal burst inside him as he held the knowledge that his cum was going to remain inside the little boy for as long as possible. He was also aroused by the fact that he would have the boy just thoroughly fucked, and still swollen from his sperm out in public. Yes, this would definitely become an every night thing. He made a mental note to summon his dogs for tonight.
The days went on much the same. Kakashi continued to fuck his little student, a child of 11 every night, sometimes introducing toys and occasionally he let his nin-kin in on the action. Naruto remained permanently bloated from the cum filling him, believing it to be because of his diet. Kakashi always made him a lot of food and put this weird white stuff on every one of his meals, though his teacher never ate it himself.
Months later, Kakashi no longer needed to drug little Naruto, as the kid slept like the dead as soon as his hole was filled. Naruto would shift restlessly in his sleep until Kakashi forced his cheeks apart and speared him on his huge cock. Only once he was knotted and full of cum did the child fall into a deep restful sleep. The only really close call Kakashi ever had was the first night he had forgotten to give Naruto his sleeping meds. Just thinking back on it still made him hard.
Kakashi had been close, so very close. Balls already starting to tighten, he plundered the delectable ass, hips pistoning in and out, over and over. He was several thrusts away from completion when Naruto moaned and shifted, eyelids fluttering but not opening. Kakashi had frozen in place, dick hard and wanting, head just barely penetrating the so very tight fuck hole.
“Kashi?” Naruto had mumbled sleepily, still on the precipice between dreamland and reality. Kakashi could tell he wasn’t quite awake yet, but he was getting there. He couldn’t pull out because it might wake him fully, but he didn’t know if he could stay like that until he fell back asleep. Already his body was trembling and his cock twitching, needing to cum so badly.
“Go back to sleep, little Naruto, you’re just dreaming,” Kakashi whispered quietly, hoping to speed the kid along to sleep.
“Doesn’t…” Naruto mumbled, eyebrows furrowing. “Feel right…”
Kakashi shifted slightly, moving to look at the child’s face. Naruto was laying mostly on his stomach, but still slightly on his side, his teacher hovering over him. “What doesn’t feel right?” He bit out, cock throbbing as he forced himself to remain still.
Naruto’s face scrunched up, eyelids again fluttering. “Emp…ty…”
He felt his dick twitch as the word left the petal pink lips. Shifting his hips so his cock pushed a little deeper in; Kakashi watched fascinated and a little more than excited as Naruto sighed and relaxed more. “This what you want, Naruto?” Kakashi asked as he forced his cock in slowly, stopping only when the knot brushed the entrance. When Naruto hummed in satisfaction, Kakashi groaned. “Don’t worry, little Naru, Sensei’s gonna fill you up so full you won’t ever be empty.”
Kakashi made several shallow thrusts, pushing his knot in further each time. He had to hold back his moans as Naruto mewled each time his teacher’s cock filled him. Kakashi could feel the hole contracting and tightening each time he pulled out, before relaxing as he pushed back in. God, the kid was born to take cock.
He looked down at his student, who was getting closer to sleep the more he was fucked, and Kakashi gave a vicious thrust, snapping his hips so they slapped against the child’s bum. Kakashi was testing him, seeing just how far he could push before he went too far, but sleeping Naruto didn’t seem to mind at all. Kakashi brutally plunged his big aching cock deep into the child’s tiny little boy cunt, driving his knot past the tight ring of muscle.
Groaning in completion, Kakashi exploded inside his student, washing his greedy fuck hole with his seed. He bred the boy for a long while, watching as the small stomach began to once again distend, filling with his teacher’s sperm. Naruto sighed in satisfaction before falling completely into the world of dreams, filled with a huge cock and buckets of cum.
Ever since that night Kakashi had forgone using the drugs and instead reveled in the idea of fucking a nearly conscious Naruto. Days later his student confided in him that he was having strange dreams of being a shell, empty, and wanting. And then Kakashi would come along and made the feeling go away. Little Naruto had looked so confused, but Kakashi’s pupils dilated as his cock started to swell. After that he continued to push, testing how far he could go.
Weeks after the first incident, they had been watching a rather boring documentary when Naruto had nodded off, head in Kakashi’s lap. Kakashi, of course, had taken advantage. He fucked the boy’s greedy little cock hole with his fingers right there on the sofa. He had even decided to take it a step further, and stroked himself to full hardness. Grabbing his dick, he traced the head of his cock against the soft lips, leaving behind a trail of precum, before forcing the tip in. Naruto had started to suckle automatically and Kakashi had fed him a good sized helping of his sperm a while later, still fucking him with his fingers.
The years would pass the same way, until Naruto eventually moved out. He spent several sleepless months before asking Kakashi to move in with him, seeing as for some reason he couldn’t sleep without his Sensei there. Kakashi happily obliged, and Naruto never found out why he couldn’t get proper rest unless the Jounin was there. And Kakashi never told him.
