Adults are truly filthy creatures

Summary:

They said it is important for the older one to help nurture the younger generation.

That, Kamui quite understands. But in this situation, which one should be the "younger generation" here?

Notes:

18! Abuto × Aged up! Kamui

-post silver soul arc
-Kamui here is in his mid-twenty, or you can think he is in his thirties here! That would work, too.
-Young Abuto. I didn’t have a clear age in mind when I wrote this, but 18 should suit the tone of this fic the best.
-This is a pure car ride, or a lemon, if you like to call it that.
-But honestly this is 2025, who uses those terms anymore??? This is just a porn fic, pure fucking lol.
-Many fabricated characteristics. After all there is too little info about how Abuto in his younger days behaved… oh what I would give for Gorilla sensei to tell us more about uncle’s past.

 

Uncle rabbit, as he is in canon, is already hard to write. But who would know that his younger version would be even harder…oh uncle. By writing this fic made me realise this villain looking man in his 30s is actually never letting people know about his past. I wonder if Kamui even knows all of it. Because when it comes to vv’s life, this uncle rabbit knows more than half of it(he even raises this little rabbit himself…). But when it comes to uncle’s, it is full of void and mystery. All I know is that this uncle is a very handsome man in his younger day😔

(See the end of the work for more notes.)

Work Text:

The universe sure is made up of unpredictable factors. Because, why, in the middle of a rare leisure day Kamui has, he suddenly finds himself in some strange dimension.

And he isn’t alone. In a square space with no window or any sorts of gap to show that it actually connects to somewhere. Kamui finds another victim to this phenomenon. Though he doesn’t know whether to call this a pure incident or some bad joke, those who call themselves ‘fujoshi’ joyfully weave into existence. But the man, or rather young man he finds himself being trapped with is in fact, a very familiar person.

The same dull, listless dark color eyes with a neutral expression, although its owner from time to time will deliver a cynical smile to people. It’s also quite hilarious how much different a beard or stubble can affect how people will perceive your age. Not to mention a sand color hair which styles in a short length.

Or to put it simply, the person right in front of Kamui here is Abuto. But he is Abuto from back in the day when he was still a young man, even younger than when they first met each other.

“…since both of us are trying to destroy the wall but it still remains unscratch. Then what should we do now, mister?” The young Abuto asks, voice reluctant probably because he’s unsure of how to approach the stranger in front of him.

The short-haired man looks briefly at Kamui’s clothes with a frown before moving to eye the walls they try to annihilate for sometimes, yet no sight of any ruins or debris to show the efforts and progress.

Abuto's voice when he’s young, while largely holding little to no difference to when he’s older, has that boyish effect attached to it. This makes Kamui wonder if Abuto used to be a hot headed teenager who got captivated by a battlefield like him ,too? Or has he always been a rational calculated type of person since the beginning.

“Ah, mister? …senior? Do you hear me?”

“Don't you actually look so easy to mess with, it's kind of cute.”

“What.”

Kamui smiles sweetly, but provides no further elaboration.

This got an awkward expression out of Abuto. He presses his lips together tightly and stares stoically at the redhead as a way to say ‘Why are you saying that’

Feeling emotionally challenged yet still wanting to appear corporate, Abuto persistently asks in a helpful tone. “Ah, anyway mister, or senior? What should we do now to get out of this…room?”

uh huh.

Kamui hums quietly as if to acknowledge the younger’s concern. Narrowing his eyes and touching his chin like how those cool and calculated characters in books and games tend to do. “…To be honest with you, I also have no idea, unless...” His voice trails off, hinting at the alternative possibility that the other yato doesn’t want to think about.

Hearing that, the young man signs hopelessly. He looks dejected and slightly annoyed by what he got put into. “Wow mister, you really are no help, aren't you?”

“Haha, that’s no good. I don't like the sound of this at all.”

“My bad, didn't know you are quite sensitive to criticism.”

“What criticism are you talking about? I mean the way you’re calling me.”

It’s the surprise and sceptical that Kamui sees adorns the young Abuto’s face. These expressions look so foreign and out of place displaying on the person who usually has either sarcastic or deadpan ones. He couldn’t help but observe it with interest, intensely locking his eyes with the other person’s every move.

It must have unnerved Abuto a lot. As he seems to stare back with defiance and wary. The apathetic expression he always wears disappears and is replaced with a sharp stare.

”What’s with that stare? ‘Mister’ it as if you are a creep. Why are old people always so weird?”

With the challenging tone even more foreign to Kamui’s ears coming out of Abuto’s mouth. The redhead readily accepts the younger following provocation with glee. “It’s kind of pissing me off being toyed with and ridiculed like that. I would like you to stop or this is going to end up hurt.”

Kamui laughs joyfully, feeling so excited to see Abuto being the first one to propose a duel. Something he always thinks will remain just a fantasy for the longest of time up until now.

“So Abuto used to be a hot headed brat, too… Ah, this is so funny. I really wish to see what face he would make when remembering his old days.” He says to himself, not caring if the other will hear what he’s said.

“Hey mister, how did you know my name?” The young sand colored hair rabbit asks, voice low and cold. His stance becomes cautious and full of murderous intent at hearing his name being uttered from Kamui’s mouth.

“I told you I don’t like the way you’re calling me, am I not? How about we come up with a way to change that. Let’s see, I prefer something personal and showing off our closeness…”

”Hey, I ask you a question!”

“Ah, why bother thinking? Just my name will do, isn’t it?” “Don’t mess with m—”

Before Abuto could finish his sentence. The redhead suddenly closes their distance, faster than he prior expected thus making him alarmed and fully got into a fight or flight mode.

“Kamui, that’s my name. And you can call me that.” he leans his face even closer to Abuto’s, simply invading the other’s space. With the close distance between them, they could feel each other's breath and the radiating body's warmth. It got Abuto off guard so much that he instinctively attacked the approaching yato at his vital spot, though all of his moves were being deflected and negated, leaving him vulnerable and at the mercy of the other.

Kamui grabs the younger’s shirt collar with a firm grip forcing Abuto to lose his balance. And because of this grab, Abuto has to lean his upper body down into perfect position to take a punch from someone shorter than him. Yet the lethal blow he expected never comes, and instead Kamui just seems to enjoy invading his personal space.

Even in his young age which still retains the boyish structure and not fully developed body yet, Abuto still stands a good centimetres tall over Kamui. Their frames are also different, with the younger one lean into a sturdy, thick chest and narrow waist. Contrast with the redhead overall lean build.

The sudden movement and how the redhead time his steps shows Abuto the unbelievable fact that his every move got see through. It is as if this person has known him for a long time, sparring with him and learning him through and through to the point of knowing his breath.

It’s uncanny, actually. To think that a stranger you got put together in a strange room or some sort of unknown dimension is knowing you so well.

“And for why I know your name… hmm, Abuto may not know this yet, but we actually are sooo close to each other. You and I are always together, doing things together!” Saying that, the red-haired yato sends Abuto a vague smile.

Maybe he really did grow up into a perverted adult. But Kamui finds himself being a bit more touchy than normal. He feels quite curious that he couldn’t stop placing his hand on the other’s body. He frees Abuto’s collar and instead moves to rub his hand on Abuto’s forearm in an intimate manner. Seeing mixed emotion in the younger’s eyes, Kamui even feels more courage to continue.

“What are you even talking about? I’m pretty sure I don’t know any people that even remotely look like you.”

“Hehehe, you will know when you grow up, kid.” Kamui says with a smile so bright and cheerful. One could say that he waited for the day when he could say this to someone for a long time.

He ‘gently’ pokes Abuto’s pectoral. After seeing him straighten his back into a proper standing posture, Kamui casually brings himself to help Abuto tidy up his messy clothes. He is even feeling generous, raising his hands to comb the younger’s hair back into a proper state and smile proudly after he is done.

Albeit blushing faintly at the unexpected caring act of Kamui, Abuto steps back to create more space between them. Not caring about the disappointment and disapproval expression the redhead makes upon seeing him do it. “Let’s go back to the most important matter here. How are we going to get out of this room, mister Kamui?”

“Just Kamui is fine, it makes us seem closer that way, no?” Kamui straightens his sleeves and moves his braid a little before continuing. “Didn’t you read that paper over there? I think that’s the condition we have to fulfil in order to leave here. It’s very simple.”

The ‘over there’ Kamui mentions is the bedside minidesk in the corner of the room, right beside the queen size bed adorned with heart shaped pillows. The place and furniture Abuto tries to ignore to his fullest ability.

“That’s ridiculous. Why should something like that be able to get us out of here?” The younger one gulped, face strains while trying to say the content of the paper. “To have sex with the other people in the room— who could do that? With a stranger?”

So what troubles you is not my sex, but my status as a stranger? Having come to this conclusion, it makes the redhead chuckle a little to himself. Of course Abuto is a liar. The old man Abuto who used to deny having a feeling for Kamui, using some poor excuse as he doesn’t interest in men, yet so enthusiastically fucked him and being head over heels with him since forever.

“…A certain someone I know used to tell me that the more you grow up the easier you ditch your heart when having sex. The core is to keep things casual and boundless until you find your chosen one, you know. The concept of a one-night-stand, you can say.”

“That person sounds like a playboy who toys with people’s hearts like they are disposable.”

“Agree, that's why I beat him up. And made him make up his mind whether he dare to not put his heart and real feelings into it or not. By the way he ended up choosing me, great choice don’t you think.”

“…So that’s your lover!?”

Abuto grabs his face which is distorted into a funny expression, at least in Kamui’s mind. He is clearly so distressed it makes Kamui laugh. “Why are you laughing?! This whole situation forces you to cheat on your lover and make me a homewrecker!”

“Oh, only if you know…” “What do you mean?”

Kamui flashes the younger man an indecipherable smile. He plays with his braids hair while speaking in a soft, slow voice. “While your contorted face is absolutely entertaining for me, it won’t be fair to keep Abuto in guilt…”

“So even if you wouldn’t understand this for now, Abuto won’t need to feel guilty. For he has every right to hold me. And he should be delighted and grateful.”

“You are talking nonsense again.”

Abuto blushes. His face and ears become obviously red akin to a tomato. Kamui could hear his stammer breath and shy gasping upon hearing his words. Truly a young boy whose heart still retains part of hope and innocence.

Even the roguish uncle with so many shady deeds under his belt like Abuto used to be so naive. The redhead finds this very interesting. Abuto, who always ends up spoiling him, is no doubt a mature and rational type of person. Cool headed and great at reading the room, he is the type of person you would think of never being deceived. Yet here comes his innocence fully on display when it comes to the matter of intimacy. It makes teasing him feel so tempting yet guilt-inducing.

Judging from his clothes, the young Abuto standing here should have already joined the Harusame 7th unit. He is the member of the largest and most dangerous space pirate group, but he still has a tenderness in his heart. If you ignore the way his eyes mostly stay dull and listless.

“How about we start now? While I would like to see more of a young Abuto, he still has a very important mission to do, isn’t he?”

In the end, to the young man everything Kamui said was like a riddle. The older yato talks like he knows him well. His light color eyes also pierce holes in him with affection and familiar feeling in his gaze. It is confusing. But Abuto finds himself irresistible to the person in front of him, like a moth to flame. This person could bring him to his own ruin and Abuto would still willingly follow him.

All of this towards a stranger he first met in some weird dimension. Who also acts weird and speaks weird. Abuto must lose his mind if he chooses to play along with him.

Contradicting to all of his self preservation senses, the younger man here heard himself reply. “I have no clue what’s the mission you mentioned… but let’s start.”

 

——
They find themselves settling on the bed. Their clothes disheveled and barely hung onto the bodies as the two yatos let their instincts run free and roughly put their hands on each other.

Kamui’s kneeling between Abuto’s legs. He put his hand around the other’s shaft while leaning his face close to it, breathing hot air over the sensitive organ with vigor.

“Aren’t you too worked up for someone who said he couldn’t do it with random stranger.”

“Every healthy person would also get worked up if he got stimulated directly on his dick, mister.”

Kamui tightens his grip on Abuto's cock. It’s a warning for the younger man to do better about his word. The pair of blue eyes looks up into the dark red ones, making Abuto shivers and gulps, yet his manhood still fully erects.

“…Alright, I actually find you quite erotic. I’m hard for you...Kamui.”

As if to reward, Kamui changes the strength of his grip into a gentle caress. His hand playing with the slit, stroking up and down spreading Abuto’s precome all over his cock to make it become slippery.

The redhead narrows his eyes. He smiles seductively before opening his mouth hovering above the erecting cock, tongue narrows to prod at the head and circling it teasingly. Kamui pressed his tongue flat against the underside of Abuto’s cock, feeling its warmth and quivers. He continues licking and dragging his tongue all over Abuto for a while, before swallowing it deep until the shaft hits the back of his throat in one go.

As expected of the yato race, Abuto has an impressive size dick he could use to back up to what he’s boasting about. While Kamui is quite familiar with it, he still struggles to fit it in his mouth entirely. Even right now when it strucks at the back of his throat, the red haired yato finds that he just swallowed it halfway. So he made do with the part he couldn’t swallow by working his hand on it.

Kamui sucks on the part in his mouth gently. He swiftly moves his tongue to press and probe against the spots he learned by experience that would make Abuto’s head light with ecstasy. Along with the contraction of his throat doing to the sensitive head. It is not hard to see the sand color hair young man inhale roughly while buckling his hips, chasing for more.

To be frank, it’s the inexperience that captivates Kamui the most.

While he likes it very much that the uncle Abuto knows what he's doing and would wring out Kamui until all he could do is lie in bed, head feels like goo from pleasure. He also likes it when he has the other in his palms and to play with him whatever he wants. So the role reversal he finds in this current situation is a pleasant surprise for him. One that Kamui wanted to explore many tricks he could think of.

He hollows his mouth, suckles on the throbbing rod in a specific way and begins to move his head. This allows Kamui to take the younger man deeper, creating a lewd, wet noise with his motion.

At first Kamui thinks of letting himself be used to the sensation for a moment. But it seems Abuto is having a different idea as instead of being a good boy and letting Kamui set pace, he initiates an unexpected move.

Familiar yet different large hand places on the pinkish logs of hair, grabbing it firmly. Kamui hums in his throat letting the vibration stimulate Abuto more as he watches with anticipation of what the young man will do.

“I already said it. I don’t like being toyed with and ridiculed.” With a determined expression, Abuto grits his teeth and thrusts his hips.

The sudden movement forces Kamui to take the other into his mouth entirely. His lips touch the base of the cock, pressing against the pubic hair. Due to its size, Kamui finds himself struggling to breath with such a monstrous thing in his mouth and so deep in his throat. But the sensation of being filled to the brim and the lack of air somehow are very erotic to the red hair yato, his eyes crescent and cheeks reddened.

Kamui must be breathing hard, as the air seems to be humid from his huffing. His face feels so hot, his jaws open wide obediently.

“Do you even anticipate this? ….Adults sure are all weird and filthy.” Abuto snickers to himself, smiling cynicism as he starts pistoning his hips, fucking into Kamui’s face.

He grabs a handful of Kamui’s hair, his other hand placed at the side of Kamui’s face, locking him in place for more precision. The young man closes his eyes from overwhelming sensation, yet he continues to thrust his cock mercilessly.

To get your face being hammered by a sizable cock sure is no easy job. The collide force alone can make people feel dizzy, not to mention the blockage of air tunnels that make you can barely breath. Kamui, even with age and experience to mentally prepare himself, finds it actually harder to keep up with the young man than he originally thought. Not that he would give up.

Even on the verge of losing his mind, Kamui deliberately sucks harshly on the cock head whenever it retracts from the movement. He relaxes his throat to make it easier to accept Abuto, letting his drool lubes up the area with no regard of how much of a mess it would make. The strings of saliva create lines between Kamui’s lips and Abuto’s groins, ensuring the sloppy impression to match with the lewd flesh slapping flesh noises that has been going on from Abuto thrust.

Increasing the force he uses to hold Kamui in place. The younger yato pressing the other face closer to his groin and with a loud grumble sound akin to a low moan, Abuto ejaculates directly into the older yato’s mouth. Making Kamui has no other choice than to swallow it all.

The young man must have purposefully done this as a petty revenge for Kamui toying with him earlier, unknown to the fact that Kamui actually doesn’t mind, and intends to do it from the start.

Slowly catching his breath, the redhead leisurely draws back. Letting Abuto’s cock free from his mouth with a loud, wet ‘pop’ sound. Strings of clear saliva and murky white liquid adorned his lips and Abuto’s rod, connecting them. Kamui looks at it with his eyes half lid, laughing cheerfully at how straight out of erotica this looks.

Kamui flicks the sensitive organ, Abuto vinces hard as his manhood being tortured in its over sensitive state.

“Ugh, can you not do something strange…?” “But look, isn’t this a pure pornography scene? Don’t Abuto find this amusing too.”

Kamui says, urging the younger to look at his own crotch.

The penis, which is just ejaculated, becomes softened yet still somewhat standing. But the wet gleam and a flushing-disheveled face of Kamui that press closely to it add an erotic appearance to the scene by a lot.

The redhead hums, looking at Abuto as if to say ‘see, am I right?’ And the younger couldn’t help but agree with a blushing face.

Kamui blows air onto Abuto’s softening cock then starts licking it clean, lapping up the residue of semen that was left on it like it is a fine delicacy. “Since Abuto is still young here… he should be ready to go for round two soon, right?”

Upon hearing that, Abuto snorts. “You truly are crazy. Has anyone ever told you that?”

“Abuto should know the answer better than anyone else.”

“So that is a yes.”

 

——
Banters, yet the young, strong arms still willingly reaching for the redhead’s waist. The sand colored hair man pulled the other close into sitting on his lap. Kamui cooperates very well, he even lifts himself to find the most comfortable position on Abuto’s lap, purposefully grinding his rears onto the still refactoring cock.

Yato as a race truly is astonishing, so aspiring in many aspects. As not long after, with just a little pecking there and there and some groping, Abuto’s now ready to go again.

Kamui looks down at Abuto Jr. which is twitching begging for attention right now. Decides to lend a helping hand, Kamui rubbing the engorged penis swiftly makes Abuto let out a surprise yelp that turns into a moan.

When it’s clear that Abuto has become completely hard. He pauses all the motion. Leaving the weeping cock alone with its owner panting hard.

The redhead stares with great intensity, lips curve up into a maddening smile as Abuto becomes so putty he is at the mercy of Kamui’s hand.

Young people often have no self-control, and that is why they’re quite fun to fool with. Is what Abuto had commented about their newly joined recruits. This statement seems to hold true with even the one who said it also makes a great example of it.

“Hold on a bit longer, Abuto. I still don’t have all the fun yet.” Whispers directly into the younger’s ear as Kamui discarded his pants, stripping bare from the waist down to his feet. Flinching a little when he’s exposed his own fully erected penis to the chilly air.

It’s going to be such a pain. Kamui knows this from the start since there are not any lubricants to use, well, except for their own saliva. But the point still stands, in the room where it’s the rule that requires them having sex in order to leave, there’s a surprisingly lack of equipment and mood inducing features in it. (If you're not counting the large bed, that is.)

Yet, if you ask if Kamui has any problems with it? Then the answer would be no, he doesn’t care. As long as there’s a functioning surface and ‘functioning’ Abuto, he is sure he can make do with anything.

Kamui starts by pressing their cocks together. Spreading the clear fluids they secrete all over the organ for extra slippery. His other hand guides Abuto’s hand into his mouth, kissing its rough pads and sucking them wet as a showcase to what he’s going to do next.

Seeing the flustered look, Kamui parts from Abuto’s hand and presses his lips against the other’s. He turns it into a passionate kiss, devouring his breath while cupping at the base of Abuto’s neck. Not caring how naughty the younger’s hands seem to wander blindly on his body, on the contrary he even encouraged them.

Naive and lack experience, yet he sure knows at least the basics of what is needed to do. As Abuto’s hand reluctantly gropes at the redhead’s rears, reaching the tightly shut ring of muscle. He circles above the hole for a moment before prodding into it.

Which to the younger’s surprise. He finds his fingers getting passed inside the tight muscle easier than expected. It seems Kamui either recently did it, or his body has become used to the activity and the shape of what’s often invaded into it, this part simply slowly being shaped accordingly.

Out of breath, Abuto can barely draw back from the kiss with a wet noise as he asks the older one. “You… seem to be familiar with me far too much. Care to elaborate this?” “I already said it before, we are so close with each other, Abuto is just not knowing this yet.”

Kamui kisses his chin while pressing their upper bodies together, highlighting how differ the sizes and muscles seem to be despite being the same part of the body. He would have the mind to explore and compare the difference of their bodies more, if not for the fact that Kamui starts to feel at the limits himself. His mind couldn’t focus much except to finally feel this ‘Abuto’ inside him.

He lets go of his hand. Lifting his hips high while standing on his knees making Abuto withdraw his hand from Kamui as well. Kamui’s positioning himself over the erecting genital and lowering himself precisely on it.

“Perfectly fits, right? Abuto should remember this properly. Because he will be acquainted with it for the rest of his life in future.”

“Oh my mister schizophrenic. You are talking about things I don’t understand again.”

The redhead doesn’t retort back. Instead he lowered himself more til the point their flesh completely touched.

With his eyes half lidded, Kamui’s gaze roaming across the younger man’s torso searching for something he wants to experience next. And thanks to his imagination, he quickly finds what he wants.

Kamui swipes his legs and encloses them around Abuto’s narrow waist. His hands cup the sides of short hair man’s face, ‘tenderly’ caress it.

“Do Abuto trust me?”

“...that depends on what you are going to do.”

“Love really is something you trained others for, isn’t it. To think that Abuto would normally trust and follow me no matter what…”

“Are you a landmine girlfriend or what? This ‘Abuto’ you’re talking about seems too absurd to be true–”

The young man thrusts his hips up, making Kamui take him deeper than ever. His thumb presses down the pink tongue forcing the other’s mouth open. “Are you sure you didn’t just make all of this person up in your head?” Abuto leans close and whispers, questioning.

But to be precise, the question is also aimed at himself.

It’s a stinging pain in his thumb that made Abuto avert his eyes to the source of sensation. He sees a droplet of blood seeping from his bitten finger before it is being licked by the causer, painting his sharp canine a soft red.

Kamui’s hands, which at first tenderly touch Abuto’s face, lightly drag lower before stopping at the nape of his neck. He pushes Abuto to lie down on his back, making him completely sit towering over the younger man.

Abuto doesn’t resist. Even if his instinct will tell him otherwise. He watches silently as Kamui moves his fingers and firmly wraps them around his neck, pressing on his bloodvein regulating Abuto’s blood supply.

The strangled man swipes his bleeding thumb on Kamui’s lower lip. His eyes lidded in insufficient blood flow and satisfaction as the soft lip that passionately kissed him multiple times today was painted red by his own crimson.

“The truth speaks for itself, does it not?”

The sand-colored hair man snickers. His stoic face lets out a cynical grin and that makes Kamui feel utterly delighted.

So familiar, it is heartwarming, even if right now he will strangle the source of his bliss with his own hands. But that means nothing hard as he could vividly feel within him the Abuto’s hardened penis from being choked.

Kamui rapidly lifts and slams down, impaling himself onto the shaft below him. He doesn’t even care about holding back. The redhead increases his force, motioning his hips into a circling movement while clenching down, making Abuto see stars.

The sound of flesh upon flesh and wanton moans fills the room. Kamui deliberately rubs his sweet spot against the penis inside him, feeling himself become putty and lose his mind every time he does it.

It’s become increasingly hard to focus, but Kamui still retains some sense to himself enough to gauge Abuto’s reaction. When he sees that Abuto seems about to lose his consciousness, he retracts his hand at the same time his sensitive spot gets rubbed inside again.

Abuto inhales harshly, feeling his blood flow freely again takes him sometimes to get all his senses back from the high clouds. Especially when your cock still gets stimulated constantly it kind of drives you mad.

“—At least know to hold back a bit, worry about the younger people, will you?”

To assert his point, Abuto gathers his strength into pistoning his hips up at the same time Kamui lowering himself down.

He grabs the older one’s waist, timing his pace to counter with Kamui's, making the redhead’s breath hitch. Kamui’s cries heighten. His eyes roll back a little as his strength scatters and his mind can’t concentrate properly.

Kamui must have given up keeping his stance. As he leans down, arms place at the sides of Abuto’s head while panting and moaning wantonly into the younger’s ear. Feasting on his flustered and agitating look like it’s his ambrosia.

Out of breath, Kamui replies to Abuto’s remark playfully. “What to even worry about? Abuto is still hard, he still enthusiastically fucks me and hold me so passionately. Doesn’t that mean all is good?”

“You have a very simple mind. It intrigues me a lot.” Abuto says snarkly, face appears both amusing and annoyed.

“I’m currently bouncing on you and you’re calling me dumb…?”

“Oh my, this kinda makes me feel bad overworking my senior.” The younger man says with a raspy voice. His stoic face while saying makes Kamui quite curious, he lets his guard down a little.

Abuto takes advantage of this. He flips their position, pushing Kamui into lying on his back.

The younger spreads the thighs under him wide open, admiring the beautiful curves of muscle they make as he slid his hand smoothly over it.

If Abuto was to be lying, he would say the scene in front of him is nothing worth mentioning at all. But unfortunately he is too young to be fluently lying like a filthy adult, so young men like him end up feeling so dazzled, fully enchanted by the person lying beneath him.

Actually, there is something that has been stuck in Abuto’s mind for quite some time since they found themselves in this situation. Abuto confidently dared to say he could recognize Harusame's uniform anywhere, so of course he could recognize Kamui’s clothes, especially when inspecting it in close vicinity.

It is no doubt the Harusame’s 7 unit uniform. The one belongs to a high level member at that, or to be specific, a captain.

But it couldn’t be possible now, since Abuto is sure that his captain should be Houzen-dono, unless the night king secretly knows a technique that can reverse his age and he happens to look like a pretty redhead back in the day.

The possibility, of course, is vast. But to actually believe that right now Abuto is currently witnessing the distortion of time is… something else.

Abuto narrows his eyes. He feels like a headache is starting to form. So to vent this incomprehensible feeling, the young man meanly thrusts his hips forwards, letting the hot and soft interior muscles inside Kamui engulp his mind.

They moan, bodies intertwined with each other as if only by doing so could sooth their thirst.

Abuto places his hands on the back of Kamui's knees, lifting and pushing them up until he practically folds the other in half.

Due to deeper penetration, Kamui instinctively tries to escape the overwhelming pleasure. But with his legs being pinned up and bullied from the person above, his attempt is proving to be futile.

“Isn’t this your goal from the very start? Don’t change your mind now, senior.”

Kamui, on the verge of tears, writhes from ecstacy. He moans loudly without shame while hugging Abuto’s neck. His lower body lewdly clenching down on the penis inside him, deliberately chasing the pleasure but also instinctively crawling away.

“Hmm. Ah-h…My lover also told me that the princess’s mind is always fickle and fragile– so you should always capture–ngnh, that weak spot and manipulate it to your advantage…”

“That is evil, what the hell. Is your lover a scumbag or something.”

Abuto said, feigning ignorance as he deliberately pounds into Kamui’s prostate. Attacking his ‘weak spot’ while nipping on his ear.

“Ah— yes, that’s right. He’s a very evil, shady old man♡”

“He also likes to do the very same thing♡ you did but more cunning. So familiar it was thought provoking.” Is what is whispering directly into the younger man’s ear.

Abuto knows at this point, feeling jealousy would hold no difference than beating your own shadow, or that of a dog chasing its own tail. But he still feels a pang of jealousy and detest upon hearing it, especially when Kamui puts it in a way to mark their difference. So he hammers his hips in with more force in a precise motion, setting a brutal pace that utilizes the yato race’s well-known super strength.

Due to the position, Kamui's knees, which are pressed in the same level as his ears, make his whole legs visible to watch for reaction. And it doesn’t disappoint as Abuto could see with every pounding that the redhead’s feet will curl, legs pointing into the air uncontrollably. Even his hand will grip the sheet tighter as Abuto thrust into this same spot repeatedly.

This position also allows the young man to penetrate even deeper. With Kamui practically being folded into a half Abuto could directly insert himself ‘vertically’, sheathing inside the redhead to the hilt with not much effort required. So it doesn’t take long until he actually finishes, the string of white murky liquid being shot out and he gasps for air.

It’s arousing. Seeing this older man who seems to know and have Abuto completely under his palm becomes a mess. His face flushed red as he showed pure ecstasy, moaning loudly not being able to hold it back.

“It’s not good to mention another man in bed, that’s rude.”

“...Hehe, how romantic of a heart you get here. –You truly never change.”

“Knowing that, yet you’re still doing it?? Such a mean adult.”

Despite just making him ejaculate, he flips Kamui lying on his stomach. Everyone with even a little bit of yato race knowledge knows they could go all night, so just a tad bit of being overwhelming is nothing to them. This is not even near enough to break a yato mind.

Pulling the redhead’s legs up in order to make him props on all fours. This position outlines his slender yet well toned body, making the sculpted muscles of his back and limps bulge up while glistening with sweats.

It’s truly a beautiful body. Abuto finds it arousing even more with how much strength and sturdy this seemingly thin, well-built body actually holds. He doesn’t even need to hold back and can wholly deliver his thrust in full force.

So it wouldn’t be a lie to say that Abuto feels very excited, his head is dizzy and almost lost himself.

“You are so unfair. —How can you just appear and be able to mess with me so much?”

He asks amidst the thrust, sensing Kamui spasm and overwhelms to the point his response has been delayed. He places his hand under the redhead’s lower belly in a guise of support when in reality he just makes an excuse to hold him closer.

With great struggle, Kamui finally gathered himself enough to form a retort to Abuto’s sentences. “—Don’t be so sulky. Abuto will get to change the whole trajectory of my life, too.”

Sulky uncle, even back in your younger days you are still this nagging. But Abuto is so cute like this. Kamui personally likes it very much.

Hearing that, Abuto touches his forehead against the curve of Kamui’s back. Gathers his breath and tries to calm his mind from overthinking about what Kamui really means of what he said. Every inhale and exhale brings to him the scents of sweat and sex, also lying underneath them are faint scents of blood and bodywash Abuto always uses.

The younger man remains silent for a while, with his face concealed by Kamui’s back there is no way of telling about his facial expression that could clue on what he is really thinking about right now.

So it seems even if he told himself that and tried to find a way to distract himself from thinking about Kamui’s words. In the end he still ends up thinking about it.

Even if the body is chasing the pleasure, his mind instead is fogged by curiosity. Abuto’s hips still piston in and out, delivering pleasure to all parties involved yet he frowns.

Finally lifts his face up, Abuto realises all of his inner turmoil must look really ridiculous. As Kamui partially tilts his head back to look at him. His gaze is that of pure amusement. The affection fusing in it felt so mocking in Abuto’s mind, so the young man stopped all his motion, ready to retort with the other person above all else.

“As expected, Abuto here is still just a young rabbit after all.” Kamui says, out of breath.

“What even is that comparison? Your mockery is starting to get on my nerves.”

“Ah, you are mad again.” He replies back with a smile, his eyes crescent even more.

Feeling injustice, Abuto starts snapping his hips again as a surprise attack. His face becomes grumpy even more as the older man just lets out a lewd sound and adores expression towards him. He even gets the audacity to reach his arm back to pinch Abuto’s cheek harshly before moving his hand up to poke at his furrow brows.

He finally reached his limit. The sand-color hair man closes his eyes shut, he shakily exhales as the sensation as high as a white cloud wash over him. Abuto feels like his life got shortened by a large margin, yet he also feels like there is still a long way to go.

“Don’t frown too much, or you will end up becoming an uncle too early. Though I don’t think Abuto could escape that.”

Despite having known the fate waiting for him, Abuto still stubbornly frowns. He grumbles as his arms loop around the other’s narrow waist, tiredly says. “It’s you who has been acting all knowing about me…”

The young man doesn’t know why, but he couldn’t control his mouth and continued nagging.

“We are already fucking yet all I know about you is your name... Adults who try to appear mysterious really are all bad people.”

Kamui narrows his eyes at the speaker, scrutinizing the words he spouts knowing all too well that it would apply to Abuto himself, too.

He lives with this man for more than a decade, yet he barely knows about him when Abuto has seen more than half of his life. Even as he somehow stumbles upon Abuto in his younger days, he still doesn’t know much more about this man. So Kamui thinks the bad guy here should not be him.

Feeling a little bit offended, Kamui tangles his legs with Abuto’s, making the other lose his balance a little before grabbing his face.

With all the wet strands of sand-color hair sticking to his face, the young yato here actually looks like a pitiful handsome boy, the type that would make a lady secretly cooing at him for being such an innocent, honest man. So the redhead mercilessly yanks it to make Abuto lower his head, whispering into his ear with a cloying sweet voice. “I told you already, Abuto just needs to wait and he will get to know everything about me.”

Kamui then kisses the other lightly on the lips, before biting it until he draws blood.

“Quit being so sulky. Usually it’s your job to spoil me, so just because I’m the older one now doesn’t mean there would be any change.”

Kicking the other to make him get off of him without any pity, in which Abuto who got drained of his energy easily complies. Kamui looks at the surroundings, not surprising to find that there still isn’t any exit for them.

He gazes back at the other man who is still lying. Abuto, just by hearing the lack of comment from Kamui, instantly knows this exhaustion of an encounter wouldn’t end that easily.

“So it has to reach a certain quota… hey, don’t masturbation also count as sex? Mister… I mean Kamui, why don’t you try it out?”

“When it comes to these kinds of matters, I like joint effort more.”

Abuto feels like fainting just from hearing. But he knows there is no escape, so he guesses he will get to learn first hand why rabbit has been used as a symbol for fertility for so long, even across the universe.

 

——
He really thinks he is going to die of exhaustion, from sex, of all things.

Abuto looks at the ceiling silently, praying to himself for the exit to finally materialize otherwise his proud yato member will become disabled from overuse.

Kamui just laughs deviously at his state, his deep blue eyes filled with amusement with not a tad bit of compassion nor empathy in them.

As if realising something, the redhead says with glee and excitement. “Ah, Abuto. Please hurry growing up and don’t forget to come find me, alright?

“After all, you said it yourself. The one who didn’t stop me and brought me into this path is you, so you have to take responsibility.”

He doesn’t really know in what circumstance he would be saying that, but Abuto just accepts his fate and signs.

“...How demanding. Aren’t you a fragile, little self-centered one? Should I also call you my precious princess?”

“Hehe, that’s right. I am Abuto’s precious person after all. So you can call me any pet name all you want.”

Kamui sits up and moves toward him. His upper body towering above the younger one as he let his long, vermillion hair fall gracefully like a silk curtain. Abuto looks at him silently, still too drained to want to do anything, so he just lets Kamui do anything he wants without a care of any danger this older yato could potentially cause.

The older one places his hand directly on Abuto’s eyes, forcing his vision to be totally dark. The younger man initially feels unsure as his instinct which honed from the battlefield tells him being taken away his vision is too dangerous, but when he got his vision back and light finally reflected into his eyes again. All there is in front of Abuto is just the Harusame crew's barrack. No sight of the redhead yato here at all.

His body aches from too much exertion. But good thing that he’s a yato, so Abuto wouldn’t have to fear it becoming worse to the point of being seriously injured. Because, like hell, he could tell the medic the reason his body got into this state without looking like a mad person or a pervert sex addict.

“Such a hard to handle person… Just thinking about him is causing me a headache.” he mumbles to himself. Abuto signs loudly as he quickly fixes himself up, fearing the state of indecent he is right now will be seen.

Well, at least he now knows Houzen-dono isn’t going to be his only boss for the entirety of his life.

Notes:

I remember some fic back several years ago where abukamu called each other ‘husband-wife’ and it has completely changed my brain ever since. It is so wonderful that my(imaginary)rod becomes bricking hard. I even wonder if the author either wants to call Kamui her wife or wants Abuto to call her his wife herself. It’s must be at least these reasons for the fic to be able to radiate this much pure carnally desire to the reader.

Because I, too, also want that.
