UNTAMED

Summary:

The terror of Musutafu, Blood Riot. Some think he has no weaknesses at all. Others have heard him baby-talk to his pet hybrid, Katsuki, who rests on his broad shoulders and holds his heart captive. Only a fool would think him a weakness though.

Chapter Text

Eijirou sighs as Tetsutetsu, the Silver Serpent, goes off-topic yet again. This meeting was supposed to end an hour ago but could he expect his fellow partners in crime to stick to a fucking schedule? No!

A soft purr distracts him and he glances under the table, into burning red eyes. He can’t help but smile at how his kitten is getting angry too. He's trained Katsuki too well to ever complain but his poor baby's jaw must be starting to hurt by now. 

Eijirou ruffles his soft, ash-blonde hair and gently pushes him off his cock. He’s a stern owner but he is not cruel, at least, not to his kitty. 

"Gentlemen, gentlemen," he says, "I don't know about the rest of ya, but I'm fuckin’ exhausted. I'm gonna head. You can tell me how we've decided to divvy up the bridge massacre spoils. I trust no one will try to cheat me."

He gives the table a sharp, menacing grin and then lets out a low whistle. Katsuki immediately climbs up his back and settles on his shoulder, purring loudly as he nuzzles into his spikes.

“He just wants to go break his kitten’s holes. You think it can even talk? “ a henchman whispers to his neighbor. 

Unfortunately for him, before he can even begin giggling at his asinine joke, a blade slices through the air and cuts his fingers clean off. The henchman stares at his freshly chopped fingers, too astonished to even scream.

The lackey sitting next to him stumbles out of his chair and bows to Eijirou, mumbling out broken apologies.

Tetstutetsu sighs, “that was fucking expensive wood, Blood. You don’t gotta stain everything, ya know?”

Eijirou rolls his eyes and nods to his men to handle the asshole and walks out. He definitely plans on breaking his kitten’s holes but no one but him gets to talk about his Katsuki like that.

He prowls the streets, feeling the need for some fun to ease the storm raging in his mind. A soft meow breaks him out of his violent thoughts again. He glances up at the kitty perched on his shoulders and gives him a sharp-toothed smile. 

Eijirou holds still as Katsui bends over to cup his jaw in his tiny, tiny hands and lets his darling lick his serrated teeth. Every few swipes of that pink, rough tongue, he feels barbs lick over his gums and teeth. 

He growls and nips Katsuki’s tongue when he’s had enough. Katsuki yelps and jumps to his other shoulder. Then he smacks Eijirou’s face with his tail.

Fury shoots through Eijirou’s veins at the audacity but before it can burst through he follows Katsuki’s tail to where it’s now pointing.

Hmmm. A simple mugging. He watches curiously as a lanky man snatches a young brunette’s purse. It’s not worth taking his anger out on but Katsuki is rarely wrong about people. The young woman tries to grab her purse back, screaming expletives at the robber but he smacks her and drags her into an alley.

Eijirou’s eyes light up. There’s a target. He glances up at Katsuki to find his kitty smirking at him.

He brings a large hand up to scratch Katsuki’s chin, “fine, darlin’. Ya caught a good one. But don’t ya go thinkin’ you can get away with smackin’ me ‘round.”

Katsuki lifts his chin and turns his head away with a little hmph. Eijirou chuckles. It’s no use pretending Katsuki doesn’t love his punishments. He’s a spoiled lil’ thing.

Now for their prey.

Eijirou stalks across the street, riveted by this opportunity and with how Katsuki’s claws dig into his shoulder. His darling’s excited too.

Eijirou’s broad shoulders cut off the little light filtering into the alley, dropping the scene into creepy darkness. The man jumps in fright and the woman gets in a kick, throwing the man to the filthy floor.

They’ve reached their target and his victim before the poor thing’s scarred in any permanent way and even allowed her some violence. Eijirou’s face lights up in a savage grin. This is shaping out to be a fun night finally.

Katsuki jumps off his shoulder to some pipes along the grimy walls and distracts their victim with his own feral smirk. Eijirou kind of hates that Katsuki does a better job of it. His petrifies people but Katsuki’s? It’s unnerving to see such an angelic face twist up into that horrifying expression.

He steps to the side and gestures to the brunette to fuck off. She’s had her piece, the rest is his. She immediately runs off into the night. 

Eijirou notices she takes her bag with her. Good for her!

Eijirou glances at his kitty hissing at the man who…wait, does this asshole think he can take Katsuki? Yeah, the fucker is trying to swipe its dirty hands at Eijirou’s most prized possession.

A deep growl rumbles through his chest. Katsuki’s eyes are instantly on him, glowing like molten lava.

At least their prey recognizes that it is prey as it backs up against the wall.

“Wait, w-wait,” the fool stammers, “I - I have money!” 

“Does it look like I need money?” Eijirou frowns. Katsuki picked out his coat. He knows it openly announces his wealth.

“T-then what!? What do you need? I’ll give you everything! Do you want the girl? I’ll get her back!”

“Pathetic,” Eijirou sighs, “I always take what I need. A little thing like you could never ‘give’ me anything.”

Ugh, this is getting boring. One second, his quirk ripples through his hand, the other, five deep gnashes bleed through the worm that can’t even count as his prey.

It looks down at its mutilated chest as if confused by its own mortality. Doesn’t it know it’s already dead? At least, the blood pooling around its body is pretty.

Katsuki pounces on Eijirou’s chest and he quickly drops the quirk to hold his angry kitty. He’s hissing and growling. His claws swipe at Eijirou’s front, careful not to damage his coat. Thin slivers of blood seep through his white shirt.

“I’m sorry, Katsuki,” he croons, “it upset me! Thinking it could best ya!?” he lets out a loud laugh, “come on, darling. It wasn’t worth it.”

Katsuki gets up in his face with an angry meow.

“Yeah, yeah, ‘course, ya coulda handled it. But you deserve better than that, don’t ya?”

Katsuki’s ears relax from their pushed-back position and Eijirou takes it as a sign to pet his kitty.

“I promise we’ll find ya something better to play with,” his voice drops to a whisper. He’s going to spoil his kitty tonight. He knows it wasn’t fair to take away game Katsuki had found.

Bright lights shine through the filthy alley and a car door snaps open.

“Get in,” growls the angry driver.

“Aw, c’mon, Meens, I didn’t even go that far!” Eijirou pouts. It’s easy to give his men the slip but Mina and his inner circle always give him so much shit for just wanting to blow off some steam.

“Another fucking mess to clean up,” Denki sighs as he gets out from the back seat.

He walks over to them and glances at the dead body. He opens his mouth to ask a question then thinks better of it instead, reaching to pet Katsuki.

He gets bitten.

Eijirou laughs, “come on, darlin’, don’t be mean!”

Katsuki digs his teeth in deeper.

“Okay, ow, okay, okay, I’m sorry, I won’t touch again!” Denki yelps.

Katsuki lets him go but not before swiping a finger through the little blood that has seeped out and bringing it up to Eijirou’s mouth.

What a sweetheart. Eijirou gives his finger an open-mouthed kiss and pulls him close to nuzzle.

“Ugh,” Denki sighs, “you guys go ahead, I’ll clean up here and find my own way home.”

One of Eijirou’s men holds the door open for him. Katsuki hops into the car and Eijirou follows. The door hasn’t even shut when Katsuki settles between his legs and paws at his crotch to let his cock out.

“Don’t make me cum,” Eijirou warns but otherwise lets Katsuki go at his own pace. Katsuki gags and heaves, still not quite used to Eijirou’s size, maybe he never will be, but forces his fat, long cock down his throat. Lewd slurps and moans echo through the car till Katsuki finally reaches his prize, relaxing as soon as his nose nuzzles into Eijirou’s thick, dark pubic hair.

Eijirou catches Mina’s eyes in the rearview mirror and winks at her. She sighs exasperatedly and speeds up the car.

He doesn’t blame her. He can’t wait to get home either.

Notes:

I had SO much fun with this fic. I haven't had the drive to write more but thought posting it here and seeing if y'all love it just as much may just work in motivating me to get to it.

The aim is also to have longer chapters and proper sex scenes!
