experience (or the lack thereof)

Summary:

“Iruma.”

“Yes, sensei?”

“You’ve clearly had sex before,” he says. “With whom?”

Iruma giggles. “Why is my sex life your business?”

“You’re fourteen years old. You shouldn’t have a sex life.”

“That’s funny, coming from the man who has me impaled on his cock.”

 

Or, in order to get his grades up, Iruma decides to show Kalego a good time for the first time in his life.

Notes:

hiiii!!! another kaliru fic! funny enough, my most kudosed(?) fic is also kaliru. clearly this ship has a good market, so i am here to deliver! it's one of my favorites.

this is a fun premise to explore with them. usually with an age gap relationship, the top/older one is more experienced than the bottom/younger one, but i wanted to switch it up. so now we have Iruma, who sold his body for money as a kid to help his parents, and we have Kalego, who is a virgin due to the rules of the Naberius clan. hope you guys like this switch-around for this ship!

please enjoy!! <3

Work Text:

Contrary to one’s belief, Iruma is not innocent.

This doesn’t mean he’s not sweet or kind. A lot of people associate innocence with downright corruption, as if there’s no bridge in between the terms, and it’s all black and white. No, Iruma is still bright and pure, the boy with a heart of gold that everyone has gotten to know.

But this also doesn’t mean his mind is totally clean. 

When he was living in the human world, he had to do certain things to survive. His parents had him apply for many jobs, much of which were dangerous or immoral for someone of his age to do. There were normal things he was tasked, like being a store clerk, cleaner, or errand boy. But these only paid minimum wage, and even with Iruma juggling two to three of these jobs at a time, it wasn’t enough for his parent’s incessant greed.

So he took to other types of jobs. Mostly, it was black market trading and selling. Drugs, typically, ones that were highly illegal, like cocaine or marijuana. There were also things like counterfeit money or stolen credit cards, as well as distribution of fake IDs. All in all, lots of things that would get him in major trouble if authorities found out. Luckily, whenever Iruma took these jobs, his parents took extra care to make sure he was never caught. They couldn’t have their little moneymaker be locked up in prison for the rest of his life, after all.

But overall, the most heinous thing Iruma ever sold was his own body.

Japan’s prostitution industry was booming, even if it wasn’t supposed to be. There were laws preventing it, but they were lax and loopholes were easily found, plus law enforcement didn’t really… well, enforce these laws. In the red-light district of Tokyo, just walking through it at night, you could be prospected by men and women alike, trying to get you to walk into one of their buildings and lose all of your money. The industry made billions, and it was wildly successful.

Iruma took advantage of this, at his parent’s request.

He wasn’t stupid. He knew what the beauty standard was in Japan, and he knew that he hit most of the marks. He was short and skinny, pale-skinned, had pretty eyes and smooth hair. He was pretty, and he knew it. And one can argue the morality of it, but Iruma also knew that he, as a young boy, would be a good target for older people with lots of money on their hands. 

So in the evenings, particularly on weekends, Iruma would take a train into the heart of the city where he knew he’d get the most business, and he would just hang around shops and clubs, wearing as little clothing as he could, and walk up to people who looked like they had a lot of money.

This was his greatest form of income. He’d bring in millions of yen per week, and it really turned things around for his family. He was able to quit his other more mundane, yet arduous, jobs and focus entirely on this. Sure, again, there was the fear of the legality issues, especially since Iruma was a minor, but like before, his parents made sure he was always safe. 

Obviously, after he was sold to Sullivan and came to the Netherworld, Iruma almost never thought about that again. It plagued his subconscious sometimes, but for the most part, he was enjoying getting to be a normal kid and have fun with his friends and go to school. He didn’t think it would ever come up again. There was no reason for it to.

Right?

Kalego sits on the King’s throne in the Royal One. He’s never found it well to sit here, feeling as if he’s committing a high form of sacrilege every time he even walks near it (hell, the whole takeover of the Royal One could be described as that, at least for some very devoted followers of Derkila). Maybe once, he decided to walk up the red carpeted stairs and fall back against it, on a particularly bad day, but he didn’t remain there for long, as it didn’t feel right in his heart.

That is to say, if just sitting in it normally, by himself, wasn’t already a crime, then what he’s doing in the throne definitely is.

Kalego will be entirely honest with himself. And he’ll never admit this out loud, but there have been a few times where the looks and personalities of some of his students have not… captivated him, so to say. Of course, he’s never actively chased after them, as it would not only violate his moral code as the Guard Dog of Babylus but many laws as well. However, there have been a few demons that have caught his eye. (He may have lied to Ix and Crocell in their small interaction during the Heartbreaker Exam.)

Iruma was not one of those students. In fact, if Kalego was to play favorites- or rather, least favorites- Iruma would be close to the bottom of the list. Maybe only outclassed by that perverted bird or the gambler. It wasn’t even really the boy’s fault, and that’s probably why he wasn’t exactly Kalego’s most hated person in the Netherworld. He didn’t actively go out of his way to make Kalego’s life miserable.

However, even by accident, he still managed to mess up almost everything. First of all, trouble seemed attached to him like a magnet. Wherever he went, something awful would happen. Walter Park, Deviculum. You name it. Kalego did eventually realize that the reason for this was probably that Iruma was a human, and just him being here upset the balance of this world. But there wasn’t much Iruma could do about his own species.

Then there was the whole familiar fiasco, which still drove Kalego up the wall. Even after they tried to break the bond, Iruma somehow managed to summon him again, which meant Kalego was stuck being a slave to this ignorant being for yet another year. And yes, while thinking about it, Iruma’s humanity is also most likely the reason for this. But it still changed nothing about Kalego’s emotions towards the boy.

Yes, all in all, while Kalego does have eyes for attractiveness, none of his gaze had ever been turned towards Iruma. He tried to avoid that boy like the plague, and yet Iruma stuck to him like a parasite. 

Which is why this current situation should not be happening at all. He should not be sitting on the Demon King’s throne, Iruma should not be sitting on his lap, and Kalego should not be liking it.

Iruma has his arms wrapped around Kalego’s shoulders. He won’t meet Kalego’s gaze, but he’ll act like he is, choosing to look at the space between his eyes or the tip of his nose rather than look at him directly. He’s anxious through his confidence, Kalego can tell. 

That stupid, dastardly unearned confidence. The trait that landed him in such a situation. Iruma had lingered after his classmates left to go to lunch, which was unusual, because on a normal day, Iruma would be sprinting full-speed to the cafeteria in order to make sure he had enough time to eat the ridiculous amount of food he ate. Once everyone else had left the classroom, Iruma had walked up to Kalego’s desk.

“I wanted to talk to you about my grade on the last exam,” he had muttered shamefully. Ah, that would have been the Astrology one. Iruma was rather poor in Astrology for whatever reason. “I know you helped Orias-sensei grade it, and, um… I don’t really know him that well, so I figured I’d talk to you about it…”

That was fair enough. Iruma had failed that exam by the matter of only one question, pushing his grade to a 49/100 when a passing grade was a 50. When grading with Orias, he’d suggested that Kalego just give Iruma the point and let him pass. But that would be breaking the rules. If Iruma wanted to pass, then he shouldn’t have gotten that question wrong. 

“I really need to pass this class,” Iruma had said. “I was wondering if there was anything I could do to make my grade go up… like, if there were any extra credit assignments I could do…”

Kalego had told him that no, there was nothing. He’d reiterated the point that, if Iruma was so worried about not passing Astrology, he should’ve studied harder. Perhaps he should have spent some extra time reviewing the textbook instead of fooling around with Asmodeus and Valac, like he often did while waiting for class to begin. 

“There has to be something!” he’d cried out, brows furrowed, a bead of sweat forming just under his eyebrow. “Even if it’s not an extra assignment for Astrology, surely there’s something else I could do… right?”

No, there absolutely was not. Kalego had further insisted this, standing up from his desk and slamming his hands down on the wooden surface. He had been able to feel a headache coming on and he had been getting really frustrated with Iruma’s pestering, and had half a mind to call on Cerberus to cast Iruma out of the room. 

And then Iruma spoke something that had Kalego stop in his tracks.

“I-I can make you feel good!”

What? What? What drugs was he on? What could he possibly do that would make Kalego feel good? A back massage? That would be nice- no, no, not from Iruma, he wouldn’t know how to do it properly. Perhaps he’d learned a special kind of spell in Momonoki’s class that he wanted to show off. But no, that didn’t make sense either, Kalego knew of every type of magic taught in the second-year and none fit that criteria. So what else could he-

Oh. Oh, no. A deep shiver ran down Kalego’s spine when he had connected the dots in his head. Surely he couldn’t be suggesting… that. It was preposterous. A teacher as prestigious as Kalego could absolutely not do such a thing with his student. It violated so many laws, legal and moral. Kalego opened his mouth to spit discipline so harsh Iruma would never be able to look him in the eye again.

But then he did not speak.

You see, despite being a middle-aged man, Kalego was, in fact, a virgin. He had never dated anyone, nor had he had sex outside of a relationship. Hell, he had never even kissed anybody before. This was mostly because of the rules of the Naberius Clan forbidding affection outside of arraigned courtships, one of which Kalego was not permitted to have, since his job was to focus on being the Guard Dog of Babylus. He wasn’t to let silly things like love or sex get in the way of his duties. 

Kalego disliked this rule quite a bit. He felt out of place as a teenager and young adult, hearing his peers talking about their relationships. He wasn’t a jealous man typically, but still, he felt envious of those who got to be a demon freely without so many rules in their lives. A demon’s entire existence was made from their desires, and Kalego’s were blocked from him. If that was the case, then what kind of demon was he?

Eventually he repressed these feelings of envy and went along with his life, trying to ignore the topic of sex. He could not miss what he did not know about, after all. Still, though, there were nights where the yearning would get to him, would crawl across his skin and through his body, and he’d have no choice but to release it.

But this. His mind had whispered to him. This was an opportunity. He knew Iruma would tell no one about it, if he went through with it. He could get what he had long desired for. No strings attached.

And if Iruma was offering, well, who was he, as Iruma’s familiar, to say no?

That was how he’d ended up splayed against the King’s throne, Iruma sitting on his lap, smaller legs wrapped around Kalego’s hips. The boy presses chaste kisses to Kalego’s jawline, the parts of his neck not hidden by the collar of his teacher’s uniform. 

“You taste good, Kalego-sensei,” Iruma whispers into his ear, lips pressed up against his neck. His short, stubby tongue swipes out to lick at Kalego’s skin from time to time, and every once in a while, Kalego can feel his dull teeth scrape along his nape. 

Kalego scoffs, “don’t say that.” As far as he is aware, demons aren’t food for humans, like the opposite is true. To Iruma, Kalego probably just tastes like… skin. Sweat, maybe, dripping down his skin as a result of his nervousness. 

He’d have to be lying to say that Iruma wasn’t arousing him. The rationality inside of him screamed against it, but he couldn’t deny what he was feeling in his heart, as well as in his body. He was familiar with the feeling of being turned on, even if he himself was the only one who could ever take care of that feeling. His erection ached against the pants he wore under his teacher’s robe, and he prayed that Iruma wouldn’t notice.

He did. 

A snarky grin forms on the boy’s face, an expression that Kalego is not used to seeing on Iruma. The human rolls his hips into Kalego’s gently, just to get a feel, and a small gasp escapes his throat. “Oh,” he whispers. “Kalego-sensei…”

“Shut up,” says Kalego. “You’ve been teasing me this whole time, did you really think nothing would come of it?”

Iruma laughs sweetly. “N-No, it’s okay,” he says with a smile. “I was expecting it… I wanted it to happen, actually.”

What a brat, Kalego thinks. 

“If you want, um…” he says shyly, twirling a strand of his hair around his finger, “I could help you out with your little… problem.”

What an absolute brat, Kalego hisses mentally. But he couldn’t deny how his heart leapt when those words left Iruma’s mouth, and how his erection ached so much that it was beginning to hurt. Iruma smiled up at him, innocent in every way except for the look in his eyes. “Fine,” Kalego spits. He puts his hands on Iruma’s waist and pushes him off his lap. “Since you’re here, you might as well make yourself useful.”

Iruma grins widely, eyes full of excitement, and it makes Kalego feel sick and a bit dizzy with arousal. Iruma moves back to sit on his knees in front of the throne, at just the little bit of space there is before the tiny flight of stairs leading up to the platform. Kalego lifts his robe out of the way, letting the fabric pool around his waist, then he scoots forward to where he sits on the edge of his seat, legs naturally spread as much as the armrests of the throne will allow him to go.

He makes motion to unbuckle his navy-purple slacks, but Iruma shakes his head, putting a small hand on Kalego’s knee, saying, “I’ll do it.” His words seem insistent, and Kalego would feel bad doing it himself anyways, so he backs off with a near-silent tch.

Iruma’s hands make quick work of his belt buckle, pulling the leather through the loops of his pants until it slips out. He sets it on the ground next to him and gets to work zipping Kalego’s fly down and unbuttoning the front of his pants. From here, Kalego’s “problem” becomes much more apparent, embarrassingly so. Kalego shuts his eyes and tries to pretend that this is not happening.

It only takes a moment for Iruma to work Kalego’s length out of the slit in his briefs, and once he does, Kalego can hear the boy gasp. “Woah,” he whispers. It would make sense, this is probably the first time Iruma’s ever seen a dick that wasn’t his own. Kalego daringly opens his eyes to see Iruma holding him by the base, fingers tracing along the side, as if he’s measuring it. “You’re big, sir...”

Kalego doesn’t know what to make of that. Iruma doesn’t say those words as if he’s scared of his size; in fact, it’s on the contrary, he seems rather excited about this. Kalego grimaces and folds his arms, trying to ignore the way Iruma nuzzles his cheek against his shaft. He shuts his eyes again. What he can’t see won’t make him ridiculously embarrassed.

Then he feels something warm and wet touch his cock, and his entire body flinches.

He opens his eyes quickly to see Iruma’s lips wrapped snugly around the head of his dick, the boy’s eyes fluttering shut, a soft blush tainting his cheeks. He can feel the boy’s tongue press against the slit in his tip. Kalego puts his hand on Iruma’s head and grabs him by the cowlick. “What in the Devil’s name are you doing?!” he hisses quite loudly.

Iruma takes his mouth away from him and tilts his head in confusion. “I’m giving you a blowjob,” he says simply, as if it’s the most obvious and normal thing in the world. “That’s what you wanted, isn’t it?”

Kalego blinks, like what he’s seeing isn’t real, like he has to fix his eyes. “I…” He isn’t able to say no or yes, because he hadn’t exactly known or wanted anything in specific when Iruma said he’d help out with his erection. 

What exactly was there to do, anyway? The only kinds of sexual acts Kalego was really familiar with was typical penetrative sex, often between male and female demons only. Homosexuality wasn’t banned within the Naberius clan, but it wasn’t supported either, and as far as Kalego was aware, he himself was the only one in the clan who was attracted to the same sex. And the sexual education they got was bare-bones as it is, there was no mention at all of intimacy between two males or two females.

Yet Iruma, as all signs pointed to it, is male, and he is not a demon either. So Kalego is really strutting through uncharted territory here.

“I don’t have to if you don’t want me to,” Iruma says kindly. “I can try something else.”

Kalego frowns, a sigh escaping his lips. “No. Continue as you please,” he says. “I am… fine with it. I just was not expecting it.”

Iruma beams. He looks way too happy to be doing something as despicable as sucking his teacher’s dick. He nods his head quickly, with enthusiasm, and gets right back to it, wrapping his lips around the head of Kalego’s penis once again. A sharp jolt of pleasure zips its way through Kalego’s bloodstream once he feels Iruma’s warm mouth and soft tongue press against his flesh.

Slowly but surely (and still quicker than Kalego would expect), Iruma takes him deeper, and deeper, almost effortlessly. He barely makes a sound, even when Kalego knows this should choke him or at the very least make him gag. But he doesn’t, he seems to know exactly what to do in order to keep himself from needing to pull away. The boy’s hand grip Kalego’s knees, close to his inner thighs, to keep himself steady, as he takes Kalego down to the base, nose pressed against his stomach. 

Kalego breathes, watching Iruma silently, wondering what Iruma could possibly do next. To be honest, he was quite content just like this, feeling Iruma’s warm mouth around his length is good enough.

But then Iruma starts actually sucking on him, and Kalego has to throw his head back and grip the arms of the throne in order to keep himself steady.

Iruma works wonders with his tongue. He sucks on Kalego hard, like he’s trying to get something out of him. He can feel Iruma’s cheeks against his shaft whenever he sucks in particularly hard, he can feel the way Iruma’s tongue swirls and traces around imperfections and veins along his length, he can feel Iruma’s teeth gently graze over certain places in a way that doesn’t feel painful but rather adds an air of excitement to the whole experience (not that it already wasn’t exciting enough).

Kalego doesn’t even really know what to say to him. Should he encourage him? Cheer him on? Praise him? Even if he did know, words feel difficult to form when all that can leave his mouth at the moment is strangled moans that he tries to keep down. Any of the other teachers could walk into the classroom of they so desired, Kalego doesn’t believe he locked the door before he and Iruma started all of this. But it’s so hard to keep his voice quiet, when Iruma is making him feel this good.

No amount of masturbation could have prepared him for the actual mouth of another living being, especially not the minimal amount that Kalego did. He allowed himself that kind of pleasure maybe once a month, if that. His clan had taught him that seeking one’s own pleasure was dirty, immoral, and unnecessary; even if he had mostly grown out of the strict traditional values the higher Naberiuses taught him, he still couldn’t quite let himself do whatever he wanted. 

But oh, it truly did not matter, nothing would ever compare to this. Even if Kalego had never received a blowjob before, nor had he ever seen one before, he was sure that Iruma’s skill was on the higher end. Somehow. 

Iruma looks up at him with half-lidded eyes, lapis blue irises glimmering in the warm light of the Royal One. He tucks strands of hair behind his round, human ears in a jokingly innocent way that just makes Kalego more aroused. If that’s even possible! Already it’s too much for Iruma to make him feel good, why does Iruma have to look to sexy as well, Kalego should absolutely not be thinking of his student like this, but he is anyway. 

Eventually, even through Iruma’s adept skill, it deeps he can’t breathe through his nose forever, so he pulls off, saliva dripping from his lips and coating Kalego’s dick. He giggles sweetly, wiping some excess spit off his mouth. “Oh, wow,” the boy says with awe, as if he had been the one being pleasured. “Kalego-sensei, you’re incredible.”

Kalego scoffs. “What the hell are you talking about, brat?” he says. “I didn’t do anything.”

“Ah! I mean…” Iruma laughs shyly, taking Kalego’s dick into his hand again. He leans against it, getting his own saliva on the side of his cheek due to his nuzzling. “Your cock, it’s amazing… it tastes so good…”

“Where the hell did you learn to talk like that?” Kalego snarls. “Don’t. It’s embarrassing.”

Iruma pouts. “But I want to tell you how much I appreciate you!” he whines. “You always do so much for me, and you have to deal with me being your familiar… if I’m really your master- which I know you wish I wasn’t, but… if I am, then I should praise you, right? That’s how it works! Azz-kun and Clara always give their familiars lots of praise.”

Annoyingly, Kalego blushes. He folds his arms and huffs. “The sentiment is… appreciated,” he mutters. “But if you’re going to, ah… ‘praise me’, then do it in a less slutty way. You sound like a common street whore, talking like that.”

Iruma seems to shiver in delight when Kalego says those words. Kalego chooses to ignore this. “Okay,” the boy says, getting off his knees and dusting them off. “Is that enough to let me pass Astrology? Or do you want some more?”

It sounds less like a genuine question and more like a tease, like he’s egging Kalego on. Kalego, unfortunately, takes the bait. “Is there more that can be done?” he asks.

Iruma grins. It feels evil-  like when he was in his Wicked Phase, sitting across from Kalego, about to demand the rights for the Misfits to learn in this very classroom. “Oh, there’s plenty more,” he says brightly. “I can show you if you want.”

It would be stupid to bail out now, so Kalego nods.

That seems to excite Iruma. The boy steps back again and then gets to work taking off his own pants. He unbuckles and pulls off the black belt that comes with his uniform, then he kicks off his shoes and steps out of his socks (nearly losing his balance as he does so), and then he slides his blue pants off and does the same with his white underwear. Kalego expects him to go further and strip himself completely, but he doesn’t, he opts to leave his shirt on, though he does take off the overcoat of his uniform. It makes sense, he wouldn’t want Kalego to see his bare back with its lack o wings. 

However, even if Iruma’s deciding not to go shirtless, Kalego is not disappointed with what he sees. Soft thighs, pale skin, round ass, a bit of tummy that he can see peeking out from behind a white collared shirt. And of course, an admittedly small penis standing tall and erect against his lower stomach. Kalego absolutely dwarfs him in the size department. Which makes sense. Not only is Iruma young and not finished growing, but he’s shorter than the average boy his age. So even by the standards of a fourteen year old, Iruma is tiny.

“Do you like what you see?” Iruma asks teasingly, a cheeky grin on his face. There’s no shyness at all, no forms of shame or embarrassment, when Iruma shows himself off. He even spins around a few times, letting Kalego get a better view of his backside. 

“You’ll do,” Kalego says. He can’t say what he really wants to- Iruma is the most adorable things he’s ever laid his eyes on- because he doesn’t want to inflate the boy’s ego. But it would feel rude not to compliment him a little.

Iruma takes it well, grinning from ear to ear as he crawls back onto Kalego’s lap. He wraps his now bare legs around his hips and presses their lips together in a sweet but passionate kiss, one that Iruma takes the lead in entirely, pressing his tongue against Kalego’s and trying to get him to do the same. Kalego laps at the inside of Iruma’s mouth and he can hear (and feel) Iruma whine into his lips.

Something soft and cool rubs against his cock, still out and hard. It’s Iruma’s butt, he realizes. Iruma grinds against him, holding onto Kalego’s shoulders for balance, and Kalego lets him. Soft groans leave his mouth at the feeling. Iruma’s really doing everything he can to tease Kalego, isn’t he…

“Can you hold your cock steady for me?” Iruma asks Kalego once he pulls away from the kiss. “Mhm, just like that… thank you.” 

The boy positions his hips perfectly above Kalego’s dick, and alarm bells flare in the teacher’s head. “W-Wait,” he says quickly.

“What’s wrong?” asks Iruma.

“T-This… this is much too quick, isn’t it?” he stammers. He tries to remember the minimal information he was taught in regards to sexual education. “We need… you need preparation, and I need to put on protection, and…”

Iruma laughs like Kalego’s told a joke. “No, it’s okay!” he chirps. “I don’t need prep, I can take you just fine. And don’t worry about protection. It’ll be fine.”

Kalego wants to argue further, but then Iruma sinks down onto his dick like it’s effortless, and Kalego’s mind goes blank.

Warmth is all he feels for a moment. It’s tight and it’s warm, and it feels incredible. He hears Iruma moans softly as he manages to take Kalego all the way to where he’s fully sitting on his cock without an inch of space separating them. That ache that had been plaguing his bottom half is gone and replaced with the comfort of the warmth inside of Iruma’s tummy. It’s like a hug. Kalego shivers.

“Ahn,” Iruma moans, “oh, you feel so good, Kalego-sensei… you feel even bigger in me than earlier…” Kalego wants to retort, say anything, but words give way to a strained groan. Iruma rests his hand over his stomach and presses down against it, and Kalego can feel that pressure against him. Just how big is he compared to Iruma?! “Mmm… there you are, wow… that’s amazing…”

Then, as if to further finish Kalego off, Iruma lifts himself up a little and then falls back down again. This motion pushes Kalego even further inside of him, and Kalego swears under his breath as Iruma cries out with pleasure. The boy rolls his hips, lifts them and lowers them, trying to come up with a pattern or rhythm that he can keep up. 

“You are insane,” Kalego hisses. He doesn’t know whether he means that as an insult or a compliment, as it could mean both. “Does this not hurt? I feel like I’m stretching you apart…”

Iruma laughs, rolling his hips again. “Nuh-uh, it doesn’t hurt at all,” he moans. “In fact… mm, it feels really, really good…”

It should hurt. Kalego grimaces. “Iruma.”

“Yes, sensei?~”

“You’ve clearly had sex before,” he says. Iruma blushes a little. “With whom?”

Iruma giggles. “Why is my sex life your business?”

“You’re fourteen years old. You shouldn’t have a sex life.”

“That’s funny, coming from the man who has me impaled on his cock.”

Alright, fair enough. Kalego grits his teeth and rolls his eyes. Iruma’s got a point. Kalego is being a bit of a hypocrite, worrying about who Iruma is having sex with when he’s the one currently having sex with the kid. It really shouldn’t be any of his business. 

“What about you?” Iruma asks. “You don’t seem to know much. Is this your first time?”

Kalego blushes deeply. “I am not disclosing that information to a student.”

“So it is!” Iruma can see right through his facade. “I guess I should’ve expected that… I’m, um, glad I got to be your first… I hope I’m doing well! You seem to really like fucking me, which is good…”

Kalego groans. Iruma really is getting on his nerves, acting so high and mighty, like he’s so much better than Kalego just because he had sex before him. 

Still, though his mind wanders. Iruma did grow up in the human world, perhaps the age of consent in that universe is younger than it is here in the Netherworld. But still, though, Iruma is quite young, and for him to have been sexually active at an age younger than that, well, it couldn’t have been legal. And Iruma really doesn’t seem like the type to commit crimes. (Even if he is right now.)

So it must be someone here, then. Kalego clicks his tongue. Asmodeus, then, probably. He and Iruma have been practically attached at the hip since they met each other. If Iruma goes somewhere, Asmodeus follows. It would makes sense that, as two teenage boys, they would experiment with each other. Perhaps that’s where Iruma gets his experience and knowledge of sexual acts from. Perhaps Asmodeus has fucked him just like this before, or Iruma has given Asmodeus head the same way he did to Kalego prior.

That thought burns a pit of juvenile envy in Kalego’s stomach. Really? Asmodeus, as a stuck-up, annoying, obnoxious sixteen year old demon, has had more sexual experience than Kalego? That’s ridiculous. Kalego knows he abstained at Asmodeus’ age due to clan rules, but he’s a grown adult now, he should be able to do things the way he wants to. And yet, he doesn’t. But his blasphemous students are bending themselves over and fucking each other all they want.

Kalego’s hands dig into Iruma’s hips. Really, as a grown demon, he should be more than this. Iruma’s just using him as a sex toy at this point, because he’s been too afraid to do anything. But he shouldn’t. He’s twice Iruma’s size and three times his age. It’s the equivalent of a wildcat being afraid of a simple field mouse.

Without even really knowing what he’s doing, Kalego thrusts his hips up, just in time for Iruma to push his down, causing them to meet in the middle. Iruma cries out in surprise, hands gripping hard onto Kalego’s shoulders. “W-What-”

“You are mine from now on.” The words spill out of Kalego’s mouth without him even really knowing what he’s saying. He thrusts his hips upward again, and again, and again, taking full control of the movements between the two of them. “Not Asmodeus’s. Not any other demon’s. Mine.”

Iruma whines and gasps, throwing his head back and arching his back. He nods his head in agreement. “Yours,” he chokes out through a moan, “Kalego-sensei, yours-”

“I don’t know how many demons you’ve spread your hole for,” Kalego snarls, “but it ends now. You belong to me. If I have to be sworn to slavery under your familiar contract, the least you could do is let me have this forever. Right?”

“Y-Yes, sir, I won’t,” he gasps, “I won’t fuck anyone, no one that’s not you, Kalego-sensei-”

Kalego grins. “You’ve got some nerve, acting like a slut to try to get me to raise your grades,” he scoffs. “That’s the oldest trick in the book. You think that hasn’t been tried on practically every teacher in Babylus? Hah.” He lets his claws dig in hard to Iruma’s soft hips. Bruise them, leave marks, whatever. “Was passing the class really even your goal? Or did you just want someone to bend you over?”

Iruma giggles, high-pitched and airy, like only one of his lungs is working. “Mm, I’ll be honest, I do really wanna pass Astrology,” he whines. “But you, this- mm, it was a bonus…”

Hm. It’s not the answer Kalego was really hoping for, but he appreciates Iruma’s honesty, at least. He’s already failing Flight classes, due to well… the obvious, but it’s labelled as a lack of participation, which brings his overall grade down quite a bit. He definitely can’t afford to fail another class, especially when the rest of his grades are only acceptable, not ground-breaking or above and beyond. He won’t be expelled or anything, not when his grandfather is the principal, but having too low of a grade-point average could cause a demon to go down a rank.

“I’ll do it,” Kalego whispers right into his ear. He’s not sure if Iruma can even hear him over his own incessant moaning, but he speaks anyway. “I will let Orias know that I have decided to give you a bit of extra credit on that last exam, and I will let you pass. However, this must continue,” he adds. “You and I. Whenever I want to fuck you, I will. Understand?”

Tears fall out of Iruma’s eyes, but he nods anyway. “Y-Yessir,” he moans. “I understand. Thank you, thank you so much, I- nngh!”

There’s something softer within Iruma, something that feels different than the rest of his body. When the tip of his cock presses against it, Iruma cries out in a way that feels much louder and more serious than anything else, and his fingernails dig into Kalego’s shoulders, which would be highly painful if Kalego wasn’t still wearing his teacher’s robe. 

“Is that spot different?” Kalego asks. “You reacted differently.”

Iruma nods quickly. “It’s… the good… spot…” he whines. “Sensei, please, there- again-”

In response, Kalego thrusts his hips upward in that same position. “Like this?”

“Yes, yes! Please, sir, I need it, please, take me- ahh!”

Quite frankly, Kalego is a bit tired of hearing Iruma beg for him. So he decides to give him what he wants, finally. He uses all of the power he has stored in his hips to thrust upwards right into that spot that Iruma had wanted him to hit, and somehow, he hits it every time. And every time he does, Iruma cries out louder, and louder, his entire body quaking on Kalego’s cock, tears streaming down his face over his cheeks that are red as cherries, his mouth that’s leaking drool onto his shirt. 

Kalego doesn’t think he can take this anymore.

His hips give one final thrust before he feels that pressure he recognizes from whenever he used to masturbate, and soon enough, he’s finally climaxing. He knows that he probably should pull out, but he really, really doesn’t want to. 

And Iruma’s orgasming too, actually. All over himself, all over Kalego’s teacher’s uniform, which he’s displeased about but also slightly turned on by. Iruma subconsciously moves his hips a little more as he takes the blunt of Kalego’s orgasm, crying out soft, choked-out moans of Kalego’s name. 

The boy falls forward into Kalego’s chest once he finishes. Kalego wants to push him off, but he’s too tired to. Instead, he actually does the opposite, wrapping his arms around the boy and hugging him close to his chest. A hand moves up to pet down blue strands of hair, silky and smooth. “Are you alright?” he whispers to Iruma.’

“So full,” Iruma whispers back. A small smile curls up around his lips. “Did you mean what you said?”

“About raising your grade? Yes, of course. I will contact Orias tomorrow.”

Iruma shakes his head. “Not that,” he mumbles. “About wanting to… keep me. About me being yours.”

Ah. That. Those words had been said in the heat of the moment, but Kalego… he doesn’t think that he regrets saying them. He sighs. “Yes, I meant it,” he replies. “If you alright with such things.”

“Mhm. I am.” Iruma snuggles closer. “You’re so nice when you’re not being mean, Kalego-sensei.”

“Shut up.”

Iruma just laughs under his breath, and Kalego rolls his eyes and relaxes. Derkila’s throne is quite comfortable. All the guilt that had come from doing such deplorable things on such a sacred piece of history has washed away with his orgasm. 

Kalego feels tired, but it’s a nice kind of tired. It’s not like the bone-weary exhaustion that eats at him whenever the Misfits are too loud or his coworkers swamp him with work. It’s more like the kind of tired where he sinks into a warm bathtub and just wants to close his eyes and sleep.

Iruma stirs a little on his lap. “Ne, Kalego-sensei?”

“Yes?”

“I’m not having sex with Azz-kun. I thought you should know.”

“Ah. I see.”

 

Kalego blinks.



“You’re not?!”
