Summary
     Obito is deprived of his favorite pastime of being fucked senseless
     by Kakashi for a few days and he doesn't understand why. Kakashi
     enlightens him. This is the best you're going to get for a summary.
     It's gratuitous smut and an in depth description is not going to help
     you to decide whether to read it or not. The title comes from the
     fact that Obito refers to and thinks of Kakashi as his master in this
     fic and I really couldn't think of anything better. Read it or don't.
     I don't care. This is one of my rare few stories that has literally
     no plot. The rest of them at least have some semblance of plot even
     if it's just for show. This is going in it's own series because I'm
     likely to post other one-shots directly related to it so it wouldn't
     really fit into my other Kaka/Obi series.
Notes
     Before you read this, know that this is completely gratuitous smut
     that came about due to my slight obsession with Obito being fucked
     and filled with cum. He’s just fucking perfect as a cum slut, okay?
     There are other elements than that in this but only so far as kinks
     go. They have an interesting relationship. Everything here is
     consensual even though Kakashi is a little controlling and Obito
     submissively takes it.
     He understands Kakashi’s need for control and he is okay with
     submitting to that control even if it doesn’t have to do with their
     sex life. This is just how their relationship works. I understand
     this might not be a realistic representation of any of the kinks
     shown here but you need to understand that this is literally porn.
     It’s fantasy. It’s obviously not real and I’m not trying to pretend
     that it is.
     If you find that you can’t suspend your disbelief long enough to get
     through it then feel free to leave this page and stop reading it. I’m
     not asking you to slog through it if you truly can’t stand it or
     handle it. I wrote this mostly because I wanted to and I’m posting it
     because others might enjoy it too. If you aren’t enjoying it then
     it’s obvious this story is not for you. Anyway, for the rest of you,
     I hope you enjoy this very plotless smut I wrote.
See the end of the work for more notes
Obito nearly whined as Kakashi started walking away from the training grounds
without a word to him after training that day. It had been days since the last
time Kakashi had fucked him and he was starting to ache badly for it. He hadn’t
been given any cum in days! He didn’t know what he had done wrong. Why was
Kakashi pretending that he didn’t know how desperate Obito was for his cock?
He hurried after the other boy, mindful enough to make sure neither of their
other teammates saw him following. Kakashi was in an isolated training ground
with his back turned to Obito by the time he let the other boy catch up to him.
Obito approached the other boy cautiously, unsure if he had done something to
anger him recently. Kakashi usually fucked him at least every other day if not
more frequently so going without for days was strange to him now.
“Did I do something to make you mad?” Obito asked, unsure of what he might have
done. Kakashi just stared at him silently, a neutral look on his face. What was
going on? Kakashi had been fucking Obito for nearly a year now since he had
discovered just how much Obito loved taking cock. Kakashi had caught him
fingering himself while they were on an overnight mission and he had been quick
to replace those fingers with his cock.
He had Obito begging him for more before long and they had been fucking ever
since. There was barely a time when Obito didn’t have some of Kakashi’s cum
inside him, especially since he used a plug every time Kakashi fed his slutty
hole so he could keep his master’s cum inside him as long as possible. The
problem was, a plug was only useful for keeping his master’s cum inside him and
seeing as he didn’t have any of Kakashi’s cum in him he wasn’t currently using
it. Besides that it couldn’t do what Kakashi could do to him so it was only so
useful anyway.
A plug couldn’t fuck him senseless and fill his slutty hole with cum. He wished
he could keep Kakashi’s cum inside him forever but having a working digestive
system made that infeasible at best. There were medical techniques that were
useful for cleaning oneself or others out but there was nothing to stop natural
bodily functions even for a little while. Even if there were techniques for
that they would likely be dangerous to use for more than a few hours let alone
days.
Still, his cock throbbed at the thought of being able to keep every bit of cum
his master fed his slutty hole inside him even if it was just a fantasy. It may
never be a reality but that didn’t mean he couldn’t keep what cum he was given
inside him for as long as possible. There were times when he was so full of cum
from his master fucking him over and over that he couldn’t fit it all in his
little hole alongside the plug and it leaked out when his master slid the plug
into him. He loved the feeling of being so gloriously full of his master’s cum.
He never felt empty when he was that full of cum.
The days where he got to be that full of cum were some of the best days. He got
to feel full all throughout whatever mission or training they were doing that
day so he was usually constantly aroused. During those days there would be
times where Kakashi would surprise him when they were away from the prying eyes
and ears of their team and he would get him off as quickly as possible.
Sometimes he even got lucky enough for Kakashi to suck him off since he
wouldn’t have time to fuck him properly.
His master was usually pretty good about keeping him nice and full but lately
he hadn’t touched him at all. It concerned Obito more than just a little bit
because it made him wonder if Kakashi had found someone better than him. Obito
had thought he was a good cum slut for his master but something had happened to
make his master angry at him and he had no idea what it was. Had Kakashi found
someone new? Had he decided that Obito wasn’t worth the trouble anymore?
Was he withholding pleasure from him for some specific reason? That brought his
mind back to the current situation. He was starting to become nervous with
Kakashi’s continued silence. Would Kakashi be merciful enough to fill him up if
he begged him for his cock? He hoped begging would work because he was becoming
desperate for Kakashi’s cock at this point. He was fully aroused but he didn’t
dare touch himself without Kakashi’s permission.
Kakashi didn’t like it when he pleasured himself because only Kakashi was
allowed to give him pleasure. The problem was he had been withholding said
pleasure for days now. Obito was worried that he would never be allowed to cum
again if he didn’t find out what he had done wrong or beg for it. Even then,
begging might not work. At this point all he could really do was try.
Not trying certainly wouldn’t get him anywhere. All it would get him was a
longer amount of time being sexually frustrated and aching for his master to
fill his empty hole. Swallowing hard, he slowly got down onto his hands and
knees and crawled over the ground to Kakashi. Once he was in front of the other
boy he turned and presented his clothed ass to him.
“Please, master! Please fuck me! Please let me cum! I haven’t been filled up in
daysand I feel so empty! Please be merciful and fill me with your cock!” Obito
begged, his hole twitching and making the empty feeling even more prevalent. He
let out a startled breath as he was pulled back up by the hair, knees still on
the ground as Kakashi growled in his ear.
“You’ve been a naughty little slut lately, Obito. I’m very displeased with
you.” Kakashi said, his tone dark. Obito whined in the back of his throat, his
cock throbbing at the rough treatment and the dark tone of his master.
“I’m sorry, master! I don’t know what I’ve done wrong!” Obito said, knowing
very well that sometimes Kakashi just liked meting out punishment for some
imagined wrong. Kakashi growled in his ear again and spoke.
“Let me educate you then, pet. Some men have been looking at you in a way that
only I am allowed to look at you. In particular, it seems that sensei has taken
an interest in your developing young body. I don’t like it when you allow other
men to see you anything less than fully clothed, Obito. You are to stop using
the public baths when others are there or dressing in front of sensei,
understood?” Kakashi asked severely. Obito nodded as best he could with his
hair still in Kakashi’s tight grip.
“Yes master! I’m sorry that I’ve allowed anyone to look upon me like that. I
did not realize I was gaining any attention as such. Please punish me so that I
might learn my lesson from this, master!” Obito begged him, desperate for his
master to forgive him. All he wanted was for Kakashi to be happy with him
again. A displeased Kakashi was a cruel Kakashi.
“Hm, I suppose. After your punishment you will be forgiven. Ensure from now on
that no one aside from me is allowed to look upon you when you are anything
less than fully clothed.” Kakashi commanded him. Obito nodded instantly,
relieved that Kakashi was going to forgive him after his punishment.
“Yes master. I apologize for being so carelessly shameless.” Obito said
solemnly. It was the last thing he had time to say before Kakashi was suddenly
in front of him, cock exposed and fully aroused. Kakashi wasted no time in
grabbing Obito’s hair and yanking his head back until his mouth hung open. He
then filled Obito’s mouth with his throbbing organ, shoving his cock down
Obito’s throat roughly.
He held the brunette’s head as he fucked his throat hard and fast. It was only
because Obito was so used to being punished like this that he knew how to
breathe past the cock fucking his throat. It was also because of this that he
knew how to stop himself from gagging over the thick organ thrusting into his
throat or the rough treatment he was being subjected to. Kakashi only fucked
his throat so roughly when he was displeased with him for some reason.
Obito’s cock throbbed with arousal as he took his punishment like a good little
slut. He loved being used so roughly by his master even if he wasn’t using his
slutty ass for his pleasure. Even if Kakashi called it punishment and even if
it did hurt a little, Obito was just happy that he was able to pleasure his
master. That the pain and the rough treatment turned him on even more was only
a plus. He loved that all he could do was kneel and happily accept whatever his
master decided to give him.
Being helpless to do anything but what his master allowed him to do aroused
him. All he could do was keep his throat and jaw relaxed as his master abused
his throat. As much as he wanted to properly suck his master off, now was not
the time for such things. He needed to let his master completely dominate him
and show submission to him in this way to satisfy his master’s need to be in
control.
That usually included using his mouth in this way and seeing Obito completely
submit himself to Kakashi’s punishment. Kakashi was never actually abusive in
his ‘punishments’ to Obito despite what it may look like from the outside.
During these times Kakashi needed to feel in control so Obito would usually beg
for a punishment and take whatever Kakashi gave him. The use of his throat was
admittedly a little painful but he knew that Obito loved when his master used
him so roughly.
When the punishment wasn’t this it was usually stimulating Obito constantly but
denying him the right to cum until hours later. Some of those punishments had
ended in the best orgasms Obito had ever had in his life once Kakashi had
decided that the brunette had been punished enough and was allowed to cum.
Obito didn’t regret a single punishment he had ever received from his master.
He could admit that Kakashi could be cruel but it was only in the way that he
would deny Obito sex if he was displeased with him for some reason and Obito
hadn’t yet made amends for said displeasure and the reason for it. The last
couple of days were the first time since they had started their relationship
that Kakashi had denied Obito for days straight. Usually Obito was able to make
amends for whatever he might have done wrong within a day. It was only today
that Kakashi had let Obito catch him where they could actually talk in private
so he could ask him what he had done wrong.
The rough treatment turned him on but he could admit that he still badly wanted
his slutty hole punished in the same way. He wanted his master to shove his
thick, throbbing cock into his tight ass with just lube and no preparation. He
wanted to feel his master abruptly and painfully open his hole for himself with
his cock. Despite the pain it would bring him it would feel so good being
stretched so tightly around his master’s cock.
He would feel so full while being stretched open like that. His slutty ass was
practically begging for the same punishment his throat was getting, especially
without preparation. His hole clenched as he thought about his master shoving
himself into Obito in one thrust and he whined around his master’s cock. He
felt so achingly empty when he wasn’t taking his master’s cock. His slutty hole
was jealous of all the attention his throat was getting.
Finally when it seemed that his ass would never get the punishment it wanted
his master seemed close to finishing. Kakashi growled as he shoved his cock as
deep down Obito’s throat as he could and came. Obito’s throat worked quickly
around his master’s cock to swallow his load of cum and ensure he wouldn’t
choke on it. He enjoyed the small taste he got of it before it was all in his
stomach.
His master pulled his cock out of his mouth, looking pleased now as he looked
down at his pet. Obito felt hopeful at the look. He knew that Kakashi wouldn’t
look that way if he was still displeased with him. Obito allowed himself to
relax as he felt Kakashi gently card his hand through his hair.
“You’re such a good boy for taking your punishment so well. I suppose that
since you’ve been so good I’ll let you sleep over at my place tonight so I can
feed your slutty hole all the cum you want. Would you like that, pet?” Kakashi
asked, still gently carding a hand through his hair. Obito nodded eagerly,
wanting nothing more than to be filled by his master’s cock.
“Please, master! My slutty hole has been so hungry for more of your cum! I’ve
felt so empty without your cock to fill me up!” Obito said longingly, his cock
still fully at attention as it had been since before his punishment. Kakashi
hummed and carded a hand through Obito’s hair once again.
“Well I can’t let that pretty little ass of yours go hungry for much longer
then, can I? I suppose I’ll just have to feed you a little cum here and now
since you’ve been such a good boy.” Kakashi said decisively, making Obito
hesitate before nodding. Kakashi saw his hesitation and raised an eyebrow at
him in question. “Do you not want it now, pet?” he asked a little
disbelievingly. Obito had just literally begged him for it after all. Obito
shook his head quickly.
“It isn’t that, master. It’s just…” Obito trailed off, his face turning red
quickly. Kakashi was even more curious now.
“What is it? Is this too public a place for you?” he asked. Once again Obito
shook his head.
“No.” Obito said before sighing and continuing. “My ass is jealous of the
punishment my mouth got. It wants to be punished too.” He said so quietly that
Kakashi only heard it because of his enhanced hearing. Kakashi’s arousal spiked
when he heard the sentence and he found that refractory periods apparently
meant nothing when you heard something that arousing. His cum slut was so
fucking arousing without even trying sometimes.
“How does your hot, slutty little hole want to be punished?” Kakashi asked, his
voice rough with renewed lust. Obito shifted in place, far beyond aroused by
now.
“My hole wants you to shove your cock inside in one thrust with only lube and
no preparation. It wants your cock to punish it so badly master! It’s jealous
of the pain my throat felt earlier. It wants you to stretch it out around your
cock and abuse it mercilessly. It wants you to hurt me and teach me a lesson
with your cock. Please punish my slutty hole master!” Obito moaned, making
Kakashi pant in lust.
“I would be a terrible master if I denied your request, pet. Be a good little
cum slut and go bend yourself over that training post while your master gets
himself ready to punish that slutty hole of yours.” Kakashi growled, his voice
so roughened with lust that it quite literally came out as a growl when he
spoke. Obito hurried to obey, pulling his pants down before he happily bent
himself over the only waist height training post on the grounds to await his
requested punishment. Kakashi allowed himself to just admire the view for a
moment.
His hot little slut really was just too arousing sometimes. He knew that Obito
enjoyed his punishments to an extent but he had never realized Obito had
enjoyed the pain aspect of them that much. His pet’s plea for more punishment
had him fully hard and he intended to use this erection in the way his pet
asked him to. He hurried to unseal his tube of lubrication, using a generous
amount on his heated flesh before sealing it away again to keep it from being
lost.
That done he approached his cum slut and grabbed his hip with a hand, letting
him know with the touch that he was about to do as requested. He gripped
Obito’s hip tighter for leverage, using his free hand to aim his cock at
Obito’s tight, clenching hole. Once he had the head of his cock pressed against
Obito’s hole he grabbed his other hip before entering Obito in one hard thrust.
Obito took in a large breath in a gasp before crying out loudly.
It was a cry of mixed pleasure and pain. Because of that he was unsure if he
should continue or not. That changed once Obito started to beg him.
“Oh Sage master, that feels so fucking good! Please fuck me! I want it so hard!
Make me hurt master!” Obito begged, panting with lust as he begged Kakashi. If
Kakashi hadn’t just cum down his cum slut’s throat a few minutes ago he would
have cum from hearing that. He hurried to grant his pet’s wish, setting a
punishing pace that had his cum slut crying out praises to his master.
“Oh Sage! Oh, thank you master! It feels so fucking good! I love having my
slutty hole punished by your cock!” Obito cried out, his words interspersed
with wordless cries as his ass was abused by his master’s cock. If he had
thought being fucked regularly by his master felt good then it had nothing on
what he was feeling right now.
He hadn’t realized just how much he was missing when his master prepared him
before fucking him or entered him slowly. The addition of the pain somehow made
it so much better. He hadn’t realized how much he loved pain until today. He
knew that he liked the small amount he received when his master punished him by
fucking his throat but being fucked with only lube and no preparation was far
more painful and he loved it.
The pain had enhanced his pleasure so much that there was no way he could ever
enjoy regular sex again. Realizing this even as his master continued to pound
his slutty hole was a turning point for him. He realized that he wasn’t just a
cum slut but a pain slut as well and the acknowledgement of that only
heightened his pleasure. He allowed his mind to drift away with the pleasure as
he ceased to think in favor of letting himself just feel.
It seemed like it had only been minutes that he allowed himself to drift in
hazy pleasure before he felt his master’s pace stuttering. After it did it got
even harsher and the thrusts were angled so his master’s cock slammed against
his prostate every time. He felt himself rapidly approaching his orgasm. He
realized his master probably was as well if the changed pace and angle was
anything to go by.
This was absolutely glorious. He wouldn’t give this feeling up for anything in
the world. He was fucking made to take his master’s cock just as his master was
made to punish his slutty hole with said cock. He loved being filled by his
master but more than that he loved his hole being used roughly enough that it
hurt. He didn’t feel complete unless his master was filling his slutty hole up
with his thick cock, abusing it for his pleasure or feeding it some of his cum.
He was born to be Kakashi’s cum slut and only Kakashi had seen it at first. He
was so glad his master had seen how good of a slut he could be for him or he
would never have such a perfect relationship. Sure he had been fingering
himself when Kakashi first decided to fuck him but even he hadn’t known how
much he would love taking his master’s cock or how much he would love his
slutty hole being filled by his master’s cum. It had truly been lust at first
sight and neither of them had regretted it in the least.
His thoughts were cut off as his orgasm ripped through him violently. His
master was still pounding him, hitting his prostate with every thrust and
prolonging his orgasm as he himself peaked with a growl and started to fill his
pet’s slutty hole up with his cum. Every thrust into him filled him with more
cum and he loved it. His master gave one last hard thrust against his prostate
as he buried himself as deep inside his cum slut as he could and growled,
letting out a last large spurt of cum against his slut’s prostate.
Obito let out a low, satisfied moan as he was filled by his master’s cum. He
had only just finished cumming himself and the satisfying feeling of finishing
only felt better as he was filled with spurt after spurt of his master’s hot
cum. He felt his master unseal his plug from the storage seal he kept it in on
his hip and he licked his lips in anticipation. He might not be completely full
of his master’s cum when this plug went in but he had been promised a night of
through fucking on top of his slutty hole being fed even more cum.
He let out a sigh of slight disappointment as his master pulled out of him but
he was happy to feel the plug slide into him before any cum could escape his
hole. He felt his master tap the side of his hip in a nonverbal cue to listen
to what he was going to say.
“Let’s go, pet. After we get to my place we have a whole night to look forward
to. I did promise to feed your slutty hole all the cum you wanted.” Kakashi
said lightly. Although he was thoroughly fucked out and although he really
didn’t want to move he motivated himself to do so by the promise of what was to
come. He got up and pulled his pants back up to his waist, refastening them so
he was decent to travel through the village.
When they were both decent and had their clothes suitably straightened they
traveled back to Kakashi’s apartment together, being careful not to be seen by
either of their other teammates. Obito felt nothing but anticipation as he
traveled toward his master’s apartment by his side. He was really looking
forward to what his master was going to do to him. He breathed in happily when
they finally entered Kakashi’s front door. He was home.
End Notes
     I’ve been thinking about writing out their first encounter as it were
     since I wrote vaguely how it went but I’m torn on whether to do it or
     not. I probably will and once again it will be gratuitous smut with
     no real plot. I’ll likely write about their night at Kakashi’s
     apartment too but I felt that here was a good place to end this one
     for now. Writing smut back to back is surprisingly tiring. I didn’t
     even get this done it one sitting and it’s less than 5k words.
