Chapter Text
It is the most stupid fucking thing, like the universe is laughing at him. Him, Bakugou Katsuki, the great king in the mountains, a sorcerer feared for his power and his explosive temper, and his greatest gift is… purification.
The gods must laugh their fucking asses off.
It wouldn’t be that bad, except that people will literally do anything to be purified in a lot of cases… even risk Katsuki’s temper. And worse yet? The easiest way to purify people? Sticking his dick in them.
Okay, fucking them, let’s be real. If Katsuki’s gotta stick his dick in them anyway, he’s going to get something out of it.
Fucking Deku says it has something to do with the closest access to someone’s spiritual core being inside of them and sex is the best option or some other stupid mumbo jumbo. Which, fine, whatever. They’ve tried other methods, elaborate rituals… that end in fucking. Oral sex and hand jobs… that still end in fucking. Simple kissing and voyeurism… that still end in fucking. Public, private, slow, fast, ornate ceremonies, stupid words, it all still ends up with Katsuki fucking someone.
It really doesn’t seem like it should be that big of a problem, but when he had to fuck his best friend’s partner to purify him, it was definitely awkward.
As a bonus side effect, most people don’t want to start a fight with the mountain king because where else are you going to find purification-on-demand?
And it works for everything. Which is the really fucking annoying part of it. Blood curses? Hate cursed? Karmic curses? Evil-accidentally-got-its-claws-in-you curses? Made a bad decision and pissed off the wrong god curses? Turned into an animal —the frog one was really bad, don’t ask, okay—curses? Low-level curses that should easily otherwise be broken by simple rites? Katsuki can purify them all.
Which means no one is willing to start a fight with him—fucking cowards—and being the world’s most unapproachable asshole apparently deters almost no one.
Deku clears his throat, distracting him from his thoughts. He glances up, seeing Deku, Shigaraki, and Shinsou standing before him. He recoils. “Whatever it is, the answer is no,” he says immediately.
Shinsou looks mildly offended. “I haven’t even—”
“I don’t care what you try to sell me, I am not fucking another one of your corpses,” he tells the necromancer firmly.
Looking put out, Shinsou crosses his arms and says, “Ask a man to purify a corpse once…”
“You asked twice,” Katsuki corrects.
“Yes,” Shinsou agrees. “But you only actually agreed once. He says that it was less than impressive—”
“I would like to see him keep it up while fucking a corpse!” Katsuki snarls.
Shinsou seems unimpressed. “He was animated,” he defends.
“It was dead,” Katsuki reminds with a shudder. “It was like fucking a dead fish.”
“He’s not a fish, he’s an orc,” Shinsou corrects absently.
“Spinner’s not an orc—are you racist?” Shigaraki demands.
“I’m a necromancer, not an anthropologist.”
When Deku interrupts with, “Actually, since Spinner’s not technically human it wouldn’t be—”
“ Who the fuck cares?” Katsuki burst out, his head starting to throb. “The point is that he was dead! And I had to fuck it! I said never again, and I meant never again!”
“Oh!” Deku says brightly. “We weren’t going to ask you to have sex with a corpse.” Shinsou makes a disappointed sound that Katsuki does not find the least bit soothing. “Tomura and Shinsou were paid to bring you a new cursed subject.”
Katsuki narrows his eyes. “But it’s not dead?” he double checks.
Sticking a finger in his ear to itch it and looking away nervously, Shinsou says, “Probably.”
Deku flails. “Don’t say that!” he blurts. “He’ll believe you!”
“So it’s really not dead?” Katsuki asks, not liking how many times he has to keep reiterating.
“He’s not dead,” Deku confirms, exasperated. “Tokoyami was asked to secure a certain cursed individual for you to purify.”
Frowning, Katsuki narrows his eyes. That was a very particular phrasing. “And… exactly how did you secure this… individual?” he asks.
“We abducted him,” Shigaraki says drolly.
For a heartbeat, Katsuki is sure that he must have misheard that. “You… abducted him?”
“Well, abducted is a very interesting word,” Deku says nervously.
“Did he come willingly?” Katsuki asks flatly.
“Uh… not… exactly,” Deku admits.
Right. Of course not. Katsuki sighs. “All right. What is he? What’s the catch with this one?” he demands, trying to will away the growing headache, though he’s not having much success.
“He’s, uh… well… he’s…”
“Spit it out, you fucking nerd!”
“He’s the youngest prince of the Todoroki clan!” Deku says.
“... A prince of the Todorokis?” Katsuki parrots back, feeling like he’s lost his mind.
All three of his vassals nod.
“An elven prince?” he asks again, needing to be sure.
The three of them nod again.
Yeah, there’s no avoiding this headache, but he somehow resists the urge to hide his face in his hands.
“He’s really cursed?” he asks, just to make extra sure. Just to be completely certain. It wouldn’t be the first time a family member has paid his people to abduct one of their own due to other stubborn family members. Sometimes it was easier to pay for the abduction and purification and then apologize once the person had been purified. But an elf? Not just an elf, but a Todoroki?
Well, if he wanted a fight, that is certainly one way to go about it.
Deku nods. “His oldest brother is cursed with a power that harms him. The prince shows signs of the same curse and has been kept sheltered to protect himself and others.”
“Do I wanna know why we’ve got the kid and not the big brother?”
“The brother vanished a couple years ago,” Deku says, shrugging. “Whoever paid us just seems to want to avoid the same thing happening.”
Sighing again, Katsuki stands. “He’s in the usual room?” he asks. Deku nods.
Kirishima and Tetsutetsu flank him as he leaves the room, making his way to one of the several purification chambers they have built into the mountain, but it’s rare for them to have more than one person in the mountain at a time, and rarer still to ready multiple rooms. His guards station themselves by the door as he goes in, the door closing heavily behind him.
Whatever Katsuki was expecting in here, it wasn’t this. An elf sits at the end of the bed, clothed only in a red silk robe—red, the color of blood, the color of purity. His hair is long, tumbling to his waist, half of it a truer red than the robe he wears, the other half of it a pure, perfect snow-white.
He scrambles to his bare feet when he sees Katsuki, looking nervous. His eyes are as mismatched as his hair, one the gray of a stormy sky, the other a brilliant, striking blue. Around the blue eyes is the only hint of imperfection, a red-colored scar. Fine, pointed ears stick out, earrings of silver in one, of gold in the other, chime softly as he moves.
Katsuki has to remind himself to breathe. Never has there been a creature this beautiful in his halls. “Sorry,” he says, scratching at the back of his head. “I must have the wrong room.” He turns to go.
“Bakugou Katsuki?” the elf asks, and when Katsuki looks back, he’s taken a step in Katsuki’s direction, though he holds the robe together with a hand.
“Yeah, that’s me,” he says. “There’s gotta be a mistake though.”
“Must there?”
“Yeah, ‘cause there’s no way you’re this hot. I must have the wrong room.” He moves to leave again.
“I’m Todoroki Shouto,” the elf introduces himself, which makes Katsuki turn back to him. A Todoroki. Really, is there any chance at all we ended up with two Todorokis in this mountain? he wonders.
He walks back to the elf, who looks nervous but not afraid. “So they told you that you’re here to be purified, right? You good with that?” he asks, stopping just outside of his personal space.
The elf swallows, then meets his eyes, determined. “I am,” he says. “I want… no.” He shakes his head. “I need to be free of this curse.” He touches the skin around his eye, then drops to a knee. “Please, good king, I ask of your aid.”
Seeing this gorgeous elf kneeling before him makes Katsuki’s dick stir, not that it usually takes much.
Katsuki steps forward until he’s right before the elf. The elf’s head lifts, neck tilting back to look at him. He doesn’t stand. Katsuki’s dick gets harder in his pants.
“Do you understand what’s necessary to purify you?” he asks.
The elf lowers his head again. “I must submit my body to you, take you within me to purify the curse I carry.”
“Have you ever been with anyone?” he asks. He’s pretty sure he knows the answer, but he needs to ask. “Male or female?”
“No, good king.”
Trying not to twitch, Katsuki asks, “Have you ever experimented with anyone?”
“Experimented?” the elf asks, a look of confusion coming over his face.
“You know, had someone go down on you…” He can see at the blank look in mismatched eyes that he’s not getting through. “Ever put your dick in someone’s mouth or had someone put theirs in yours? Every put fingers in your asshole? Fingered someone else’s?”
The elf looks completely offended. Just great. “Of course not, your majesty! Why would you do such… filthy things?”
Resisting the urge to bang his head on the stone wall, Katsuki sighs. A virgin. And not just a virgin, but a completely sheltered virgin. He has no fucking idea why the old tales and shit are obsessed with the idea of virgins. In his experience, virgins are a pain in the ass , and the ones who have no sexual education are the worst of them. They’re awkward, inexperienced, and they freak out at completely normal parts of sex—like, in this instance, preparing for anal sex.
He wishes it were as simple as just getting someone to suck him off, but apparently that’s just not good enough for the gods. Which means he’s going to have to lead this silk-spoiled brat through his first sexual encounter.
“What do you know about sex?” he asks.
At least the slight flush that colors the elf’s cheeks is attractive. He really is gorgeous, so that’ll make this easier, if not easy.
“I know that when a man and a woman love one another—”
“I’m going to stop you right there,” Katsuki says. “We’re two men. What do you know about what men do together in bed?”
The blush deepens, and the elf looks away. “I know that a man’s rod penetrates a woman’s flower. I assume it would be similar for two men…”
Rod? Flower? Where the fuck did this elf learn about sex? Trashy romance novels?
“I hope you’ll be gentle with my hymen—”
Katsuki’s done. So done. “Stop!” he snaps, harsher than he means to be, but he’s encountered this level of ignorance before, and he just can’t listen to it anymore. “First off, only women have hymens, and they aren’t supposed to tear if you warm a woman up right. If your partner bleeds on your first time, they probably weren’t prepared enough. Even your first time should feel good. Second, where the hell did you learn this shit?”
“My… my sister would give me her books.”
Wait . “Everything you learned about sex, you literally learned from trashy romance novels?” he asks, deadpan. It’s unfortunately not the first time that’s happened to him, but they’re always the worst kinds of virgins.
The elf looks up, “They aren’t trashy! They’re passionate love stories—”
“With the sex so censored with literal flowery language that you get some really fucked up ideas about what sex is like in your head,” Katsuki interrupts, and sighs again. “Look, this is the real world, we’re both male—unless you’re hiding extra bits I’m not aware of—and how we have sex is not going to be like the novels you’ve read.”
The elf looks down again. “I will do what you require,” he says.
Katsuki wants to scream, just a little bit, but that will undoubtedly just frighten the stupid, pretty elf more, so he doesn’t. He tries to remind himself that uneducated and purposefully sheltered are not the same things as stupid, but it’s a struggle at the moment. He looks down again, seeing the elf kneeling, face almost even with Katsuki’s dick.
At least he’s pretty.
“Have you ever jerked yourself off?” he asks, needing a baseline for how completely inexperienced this elf is.
A little wary, the elf looks back up. “Jerked… off?”
Running out of patience, Katsuki kneels down to be on the same level and slides his hand into the folds of the elf’s robe, finding him—thankfully—naked beneath it, and cupping his dick. The elf gasps sharply, cock twitching in Katsuki’s hand, and he grabs Katsuki’s wrist, but he doesn’t shove him away, just holds on. “Have you ever pleasured yourself like this?” he asks, beginning to stroke the dick in his hand.
The elf makes a little noise in the back of his throat and shakes his head hard enough that his hair flies out. “No, never!” he says, sounding appalled.
“What do you do when you get hard?” he asks.
“My father’s manservant suggested that when I feel urges like this that I place my rod in cold water until the desire goes away,” he says, gasping as Katsuki twists his wrist. “It’s very effective.”
Yeah, it would be. “So you’ve never had an orgasm? Never come?”
“I… don’t know what that means.”
“Have you ever woken up in the morning after a steamy dream with your sheets wet and sticky?”
The elf closes his eyes tightly and whimpers. “Is this really necessary?”
Katsuki releases his dick, and he slumps, his dick still hard enough to tent his robe. He quickly puts his hands over it to hide it, blushing almost dark enough to match his red hair.
“I might have to have sex with you to purify you, but if I wanted a dead slab of unresponsive meat, I’d fuck more of Shinsou’s corpses.” He stands up and takes the elf’s chin in his hand, tilting his head back. “If I have to fuck someone, I want it to be good for both of us.” Mismatched eyes look away again, and Katsuki releases his chin, holding out a hand. “Stand up, elf.”
It makes the elf look back up at him again, and though there’s naivety in his eyes, there’s also a little bit of fire. “My name is Shouto,” he says, putting his hand in Katsuki’s. Katsuki helps him to his feet, amused at the way he’s still holding his robe tightly closed.
Smirking, Katsuki releases his hand and steps back. “Okay, Shouto,” he says, drawing out Shouto’s name like he’s stroking it. Judging by the way Shouto shudders in reaction, no one has ever said his name like that before. “You do know that to purify you, you’re going to need to take that robe off, right?”
That blush is really far too attractive. Shouto meets his eyes in defiance and pulls the robe off quickly, dropping it to his feet. He probably did it like that so he couldn’t change his mind, but Katsuki doesn’t care. It means he gets to see all that pale, unmarred skin bared to him. He snickers when he notices that even Shouto’s pubic hair is two-toned. He steps forward, running a hand down Shouto’s chest before combing his finger through that patch, wondering if the colors feel different. They don’t, and Shouto gasps and grabs his shoulders.
“So you’ve really never given yourself pleasure or had someone pleasure you?” Katsuki asks, sliding his fingers down to wrap around Shouto’s hard dick.
“N-no…” Shouto says, breath hitching. “Please—I feel…”
Katsuki strokes faster. He knows exactly how soon this is going to be over if he doesn’t get this pretty elf off first, and he’ll be a lot more relaxed after he comes.
“Good king—”
“I’m going to stick my dick in you. You can call me Katsuki.”
Shouto’s fingers tighten on his biceps and he bends at the waist, obviously trying not to come, though Katsuki isn’t sure he even knows that’s what he’s doing.
“I… I can’t…!”
“Let it go, Shouto,” Katsuki croons into a long, delicate ear. “Come for me.” He takes a ring between his teeth and tugs, and Shouto comes with a cry, spilling over his hand. He sags against Katsuki’s chest.
“I’m sorry—I’m so sorry.”
Wrapping an arm around Shouto’s waist to hold him up, he slides the other toward his ass. “You have nothing to apologize for,” he says. “I wanted you to come. Trust me, it’s better to do that now and take the edge off.”
Shouto glances at him through his lashes. “The purification isn’t ruined?” he asks, unsure.
Smirking, Katsuki uses Shouto’s own spend as a makeshift lube and runs his fingers over Shouto’s hole. He gasps in response and tries to move away from Katsuki’s fingers, but he has nowhere to go except into Katsuki’s chest.
“What are you—”
“To purify you, I have to stick my dick in you.” He rubs his fingers around the rim, pressing on it lightly, enough to tease but not penetrate. “Where did you think my dick was going to go?”
“But that’s dirty!” Shouto complains, then inhales sharply when Katsuki presses the first fingertip in.
“You were required to fast since yesterday, right?” he asks, tugging very gently at the rim. Shouto makes a delicious little mewl.
“Yes…”
“Most of that is so you’ll be clean.” It’s usually easier just to have males fast than to clean themselves. “You also washed before you came up here. Trust me, it’s not dirty.” He grins then adds, “Except in the best way.” He tugs at Shouto’s rim again, getting another little gasp that goes straight to his dick. “Did that hurt?” he asks, watching Shouto’s face closely.
“Feels strange,” Shouto says, but his cock is stirring again, which is a good sign.
“It’s going to feel stranger before it feels good.” He presses his finger a little deeper, and Shouto rocks his hips into it, mouth falling open. “Can I kiss you?” Katsuki asks.
Shouto’s eyes flutter open, and he looks puzzled. “Is that not allowed?” he asks.
Katsuki shrugs. “I have to fuck you, but for some people, kissing is more intimate. I like to ask.”
“Do you want to kiss me?”
Fuck me, Katsuki thinks. No one should be able to ask that question so innocently, particularly not when someone’s finger is already in their ass. This is going to be one of those rare good thing it’s only once purifications. Katsuki can imagine getting addicted to Shouto otherwise.
“Yeah, I do,” he admits.
Shouto lifts his chin and closes his eyes, prim and pure. Katsuki can’t wait to see what he looks like when he’s lost in pleasure. He leans in and starts the kiss closemouthed, gentle, feeling the shape of Shouto’s soft lips beneath his. He presses his finger a little deeper, getting another soft sound out of him. It makes him open his mouth enough that Katsuki can sweep his tongue in and claim it, burying his free hand in Shouto’s hair. It’s every bit as soft and silky as it looks, and Katsuki swallows down the little needy sounds Shouto is making.
When he breaks the kiss, Shouto’s flushed from more than just embarrassment, and Katsuki loves the look on him.
“Ready for some more?” he asks.
Looking up at him like he might be a little dizzy, Shouto asks, “There’s more?”
Grinning wide enough to show teeth, Katsuki says, “Oh, princeling, this is just the beginning.”
