When Kirishima decided to buy a hybrid, he didn't know that he would end up with the most trusted companion in many, many years in this business.

And if asked, Kirishima won't deny: the hybrid boy was pretty.

Gorgeous.

"...K-Kirishima! No! I didn't—Nngh—"

Loud growl sent shivers down alpha's spine like always. The sound of blood spluttering on the dirty concrete was lost in the guttural rumble of the hybrid.

Katsuki, his golden tiger, ripped through the clan rat's throat. That man was already a dead meat, so Eijirou decided to let his pet handle him. The boy was as bloodthirsty as he was handsome.

His mouth was all bloody when he turned to him. His eyes were glowing in the dark room. Long, striped tail was swaying back and forth as hybrid smelled the air and growled. He stretched with his whole body, yawning. His lean muscles strained as he arched his back. His dark shirt was hugging his muscled torso rather nicely, outlining his hard stomach and biceps.

He was the epitome of animalistic grace.

"Come here, boy."

With a scowl that seemed to be permanent on his sharp-angled face, the hybrid approached him with leisure. The blood spluttered on his shirt, but most of it stained his fair skin. Kirishima tsked, taking his handkerchief and cupped soft cheek. Immediately, sharp fangs sank into his hand, and Katsuki squinted his eyes at him, growling in a threat. This reaction of his wasn't something new, and alpha was anticipating it. His hands and forearms were littered with deep bites that were scarring on top of his tattoos, but he found it adorable how hybrid was reminding him that he isn't a house cat.

"Come on. I know you hate to feel it on your skin. And the ride home is long."

Katsuki growled again, for good measure, and let go of his hand, licking his lips. His sharp fangs left another mark on alpha's skin. Sated chuff escaped his throat, and he let the man wipe away the blood. To reward him, Kirishima scratched behind the round ear, finding a perfect spot. Katsuki's eyelids drooped in pleasure, and he budded his head subconsciously into his large hand. He seemed to do that more lately, as if after months in Kirishima's company he started to warm up to the man.

"You did good, kitten. Now come on, it's late."

A long tail flicked in contentment when they left the basement, leaving behind a dead body. The car was waiting for them outside, and Katsuki hissed at the chauffeur, who didn't have time to step back, opening the door for them, and the hybrid slipped inside. Kirishima looked at the man apologetically and pushed a crisp bill into his hand as a tip. His men were enduring Katsuki's ferocious attitude for the longest, and Eijirou was grateful for it.

Because despite it all, he liked the boy.

Alpha bought him at the auction his partners organized half a year ago. He wasn't in a need of anything and would have rather spend his night in his compound's hot spring, but along with his status came courtesies and responsibilities. So he had to attend.

He still remembered a boy rattling in a cage. At first, Kirishima didn't even realize what he was looking at. He saw round ears pressed tightly to the boy's head, and the blonde fluff of his hair looked almost white in the lights of the stage. But it was his tail that made alpha lean forward to see better. It was beautiful: golden, silky fur, matching his hair and ears, and there were brown stripes on it. Eijirou noticed the same stripes on the boy's upped body as the thin tank top kept sliding off the sturdy frame. His pants were ripped mid-thigh, and stripes also covered his legs that flexed with corded muscles as he paced. He was all teeth and claws, growling and ramming into the bars. His mouth was bloody too, as if he mauled someone before they put him on the stage.

The host announced the price, which Kirishima didn't expect to be so low for an alive hybrid, and no one was raising their hands to claim the boy. Kirishima assumed everyone wanted someone more tame and safer to keep around. But he watched the hybrid from the shadow of his table, mesmerized by animalistic beauty locked behind thick metal bars. As someone who had to fight for the life and privilege he had now, the sight of a furious hybrid who wasn't giving up on his freedom made him smile. He raised his hand, and the host looked hopeful to finally move on to another subject. When the sound of a wooden hummer sealed the deal, auburn eyes squinted at him all the way from the stage. Hybrid alpha boy, Katsuki, bared his teeth, and Kirishima just smiled, watching the striped tail puff up in agitation.

Later, when the boy was transferred to his mansion, he attacked multiple people who tried to unchain him and lead him to the house. The blood was everywhere, and Kirishima let his men go, stepping into the truck. The muzzle that was initially on the boy's face was now dragged to the side, cutting into fair skin deeply. It seemed that hybrid managed to tug it off a little in his struggles, and Eijirou reached to get it off. That was the first time he felt those fangs sink into his hand. It was painful; blood was trickling down his forearm, but he only snarled quietly and, with the other hand, uncuffed the muzzle.

He still remembered how dark pupils dilated in glowing auburn eyes that watched him without blinking.

Using hybrid's astoundment, alpha unchained him with one hand. The other was still in the boy's mouth as he growled, threatening and clenching his jaws. Once he was free, the tiger hybrid let go of his hand and bolted out of the truck. Kirishima only saw how a small body with beautiful stripes and golden fur leaped over the brick fence of the front yard and disappeared in the thick woods of the mountain. His men were about to rush after him, but he stopped them. It's not like he spent a whole lot on the hybrid anyway.

The boy was free and something about it made Kirishima's smile.

However, days later, one of his men stormed into his study, shouting "Kirishima-sama, the hybrid!". And surely, the boy was back. He was sitting on the high fence, munching on the dead rabbit in his hands. His tail swayed side to side, and when he saw all the men below him, he only rolled his eyes with a rumbling growl for them to stay away. But when he saw Kirishima, his eyes squinted, and he bared his teeth at the man. Eijirou found it quite strange that the hybrid returned at the risk of getting caught. He seemed to be able to provide for himself just fine, so Kirishima wondered what it was that made the boy come back. He instructed all his men to avoid any contact with the tiger if they wanted to keep their limbs to themselves and let the boy be. He concluded it was feline's curiosity that made him come back, and after some time he surely would be gone.

But he was wrong.

In a few weeks, Katsuki was sniffing around the compound, terrorizing his men with how suddenly he would appear, growling and snapping his jaws with those sharp fangs of his. He stole some food from the summer house one time, and Kirishima ordered to leave freshly cooked meals outdoors for the boy to grab. He surely did, taking them to the fence or nearby tree and watching over the clan's people training in the compound. Sometimes Kirishima spotted him climbing on the roof and basking in the sun, but most of the time feline would sit on the fence or on the tree brunches, watching and munching on his food. No one dared to step closer to the golden tiger, let alone pet him. Soon his presence was something that everyone in the compound learned to live with. The boy seemed to like the fact that no one was bothering him or trying to capture him. There wasn't any blood of Kirishima's clan spilled at the yard anymore.

Until one day when all hell broke loose.

At one of the clan meetings, things got heated. Word for word, and soon knives were unsheathed, and there was first blood on the gray pavement. But Kirishima saw the golden tail swish, and thunderous growls made everyone freeze. Katsuki was tearing one of the other clan's men apart, clawing into his chest and biting his throat out. He was dripping with blood; his old shirt and ripped pants were drenched in it, and his guttural rumble made the other clan step back. People left Kirishima's compound terrified on that day and first rumors started brewing in their surroundings about a monster that Kirishima tamed and who fed off his enemies. Alpha himself still found those rumors ridiculous because till this day, he was still bitten and scratched to blood and scars by the boy.

But that night, Katsuki struggled to get the blood off of him. He jumped into the pond and got out clean but shivering from the cool air and with koi fish in his mouth. He dropped it to growl at Eijirou, who came closer with a big chunk of meat and a towel. His throaty rumbles at the towel drying his hair seemed threatening but he didn't bit him that night.

Ever since, the hybrid stayed by Kirishima's side.

He was following Eijirou everywhere he went, keeping his distance and appearing nonchalant, but Kirishima saw his tail curling in curiosity. His vicious growls and murderous intent written all over his face scared people, and alpha found it hilarious how all these gangsters were pushing themselves into walls and out of his way every time he showed up with the boy at the clans meeting and other events. Now all the deals were going through faster with the threat of his tiger ripping people apart. His golden kitten was like a guard of his, bearing his teeth at every wrong move and growling a storm. Even if his pet still bit him often, Kirishima saw it as his spiteful character coming out of the shell. In couple months they've become inseparable, and the tiger's thirst for blood was rumored and feared among many.

Kirishima assumed it was the boy's alphan gender that made him so violent, as well as his past in the cage. But lately, he's been acting more... Eijirou couldn't pick a word for it. Soft? Yes, definitely softer than before. He even curled on the sofa and slept in Kirishima's study the other day. Usually he was watching him work, walking away for food and coming back, staining the floors with the blood of the caught prey. But he never slept in his presence. Kirishima guessed he was finally winning the boy's trust, but then other things kept happening in the course of the last couple weeks that left everyone in the house speechless.

Katsuki rubbed himself on the furniture across the house. He kept rolling on the chairs and coaches, even on some soft cushions of tatami [1]. It was odd. But then he started to pee in the house. Not in bathrooms but in the living rooms and corridors, and poor maids were left to clean up his mess. Kirishima tried to talk to the boy; he even showed him the bathrooms, beckoning him with meat. But the golden tiger only rolled his eyes, snatching his treat and scratching alpha's hands, and walked off, flicking his tail in dismissal.

Then, after some time, one of the maids found a bundle of sheets from laundry stashed under Kirishima's bed. She took it away to put it to wash, and apparently Katsuki hated it. Kirishima barely managed to put himself between the furious hybrid and the terrified maid when the boy snarled and glowed at the poor girl. He scratched Kirishima so bad he was bleeding for days, but he was glad he prevented the attack. Katsuki only calmed down when the maid threw the nearest basket of dirty laundry at the boy. He snatched everything that was in the basket and, with the last hiss, walked away.

It was odd.

And now, as the car stopped, Katsuki bolted towards the house. Kirishima shook his head, not knowing what the hell was going on in that pretty head of his. He went to shower, washing off the grime of the day. Slowly following his routine, he hummed, brushing his teeth and sanitizing the new bite that the boy gave him. He walked to his bedroom with the thoughts of taking a vacation after months of handling business in prefectures. He was a little out of breath and needed rest—

Loud purring made him freeze as he stepped into the room.

It was a mess.

The vase in the corner was broken. His closet was open, and clothes were bundled into piles and left on the floor. The blankets were pulled off the bed, and Katsuki—

Katsuki was on the bed.

Naked and rocking on the pillow.

His tail flicked up, opening his groin and backside, and as he bounced on the pillow, humping it, Kirishima's gaze immediately fell between his legs.

There wasn't a set of genitalia that he expected the alpha hybrid to have. No dick. No balls.

But a chubby cunt was glistening with slick. The pillow was soaked through.

What the fuck?!

Katsuki turned to him and let out a sound that Eijirou never heard from him. A long, pitiful keen. A call.

A plea.

"What the actual—"

The past few weeks flashed in his mind, and a realization struck him.

"You're omega... How the fuck—"

Katsuki clawed at the sheets, and the sound of ripping fabric made Kirishima snap his attention back to him. Hybrid stood on his knees and arched his back, swaying his hips and looking at Eijirou. His face was flushed, his mouth was drooling, and his eyes were cloudy. Pale skin was shiny with sweat, but the fur of his tail was puffed out as it curled above the line of his spine. Kirishima never saw him fully naked, and now he was taken aback with how prominent his golden brown stripes were. They hugged his torso, spreading to his chest and waist, down the swell of his ass and thick muscles of his thighs. They looked like battle scars, moving with every flexing muscle, and Kirishima felt his throat drying at the sight.

The boy was beautiful.

And he was horny. Was it his heat? Was this a reason for his behavior in the past few weeks? How the hell was he sold as an alpha hybrid? Did the distributors know? 

Well, it didn't matter now.

What mattered was that Kirishima had an omega hybrid in heat clawing at his sheets.

He couldn't help but feel his cock swelling under his towel. He knew that hybrid physiology was different, and even if they had the same gender as humans, people couldn't smell them. Kirishima never smelled him, just assuming he was alpha since he was told so by the sellers on auction. Katsuki's violent behavior only cemented his status in his eyes and he was anticipating his rut at some point, but now it all went out of the window as the boy had a heat instead. The golden tiger was exuding omegan behavior, presenting his dripping cunt.

For Kirishima.

Alpha approached the bed, and Katsuki perked up. Another long sound, like a moan, escaped his drooling mouth, and he shuffled closer to the edge. It was strange to see him like this. Soft. Pliant. The curve of his spine looked enticing as he purred, showing off his pussy. It was sopping wet; chubby folds of it were flushed with pretty pink.

Eijirou's dick was rock hard, and he reached to caress glowing skin. Katsuki immediately purred, staring at him with wide eyes, and Kirishima couldn't help but coo.

"You're so cute when you're not trying to kill someone... Want me to fuck this heat out of you? Yeah? Good boy... I knew I'd get my reward sooner or later for putting up with you..."

He didn't know if Katsuki was able to grasp the meaning of his words right now. He looked gone, hot and sweaty with his heat. Testing the waters, alpha reached to ruffle his hair, earning a long, throaty rumble, and goosebumps rose on his skin. Katsuki seemed so docile, arching into his hands and seeking his touch, for which usually he would bite and hiss. Was he looking at Kirishima as a potential partner this whole time? Was it the reason why he stayed and followed him around?

"Good boy... Damn, you're so wet..."

Eijirou took off the towel, palming himself. He was enamored with the boy's body. Katsuki was barely sixteen, still a kitten, but his small but stocky figure was always something that Kirishima liked to look at. He loved his pet's animalistic grace and smooth lines of his flexing muscles. He wondered how he would take him. Alpha wasn't small by any means, and Katsuki's pussy looked tiny.

He rubbed the small back of the purring hybrid, slowly reaching for his asscheeks. They were thick mounds with solid muscles under a thick layer of fat. He squeezed them, groaning. He wanted to bite into them as he fondled the boy's ass in his hands. Pale skin was turning pink under his rough handling, and Katsuki seemed to like that. He mewled at every small squeeze and pull, making Kirishima chuckle.

"You needy little slut... Should have showed me sooner that you're hungry for some dick... I would have given it to you at any time, kitten..."

Katsuki was purring, seemingly enjoying the sound of Eijirou's voice. He never seemed this relaxed and Kirishima cooed, fondling pale asscheeks. Alpha's fingers grazed the base of the swirling tail, and he absentmindedly grabbed it, rubbing on the tailbone. 

Katsuki's reaction was explosive.

He yowled, letting out a loud, high-pitched rumble. His whole body shivered, and his hips jerked in a humping motion. He turned to Eijirou with teary eyes, and his tail curled on his forearm, tugging him closer.

"Oh, you like that? Holy shit, you're dripping..."

Aroused with discovered power over hybrid, alpha stroked silky fur, tugging on the tail he hadn't had a chance to touch before. Katsuki melted into the bed, whining and shivering. Kirishima watched his back muscles flex and relax with every caress and tug. Slick was pouring out of his flushed pussy. It was streaming down on pale shaking thighs and staining sheets under the boy. Kirishima couldn't take his eyes off of it. His balls ached at the sight of chubby cunt quivering and clenching around nothing, and after another tug, he patted soft ass in praise.

"Good boy. God, you're going to be so tight..."

Touching wet pussy, alpha felt his knot swelling. It was so slippery under his fingers. He ran them through thick folds, shocked at the buttery feeling of hot flesh. Katsuki lifted his hips more, asking for it and growling into the pillow. Thundering sounds that were planting fear in many people now seemed needy and pleading. His whole body was flushed and ready for breeding, and Kirishima just couldn't wait anymore.

He nudged a tight clenching hole, massaging the base of Katsuki's tail. Immediately, hybrid moaned, and his cunt opened beautifully under insistent push of his fingers. He took two without any struggle. The soft wet hole was stretching easily, tugging thick digits in and beckoning with its heat. Katsuki kept pushing his hips back at him, snarling into sheets. His poor pussy was greedy, squelching with slick, and after another pump, Eijirou deemed him ready. 

When he took his cock into his hand and nudged soft folds, the tip seemed ginormous next to soaking wet pussy lips. The boy shivered and growled, pushing back, and Eijirou's cock slid through the wet mess of hybrid's cunt all the way up to the soft fur of his pubes. It was sloppy and sticky, making his eyes roll at the hot sensation of soft skin and tickles of thin hair.

"Impatient... Mmm... Oh, f-fuck... Okay... Okay, boy..."

Pushing in, he felt like air was sucked out of his lungs completely. He hissed at tight clench, and Katsuki sobbed into the pillow, arching his back. While Kirishima was fighting with the tight heat of hybrid's cunt, the boy was clawing through the pillow and shivering. His tail became rigid, and Eijirou rubbed his tailbone, stroking it in hopes of making Katsuki relax.

"Come on, kitten..."

After a long second, the tight hole started to loosen up, and Eijirou grunted, sweating. His cock was pulsing, his knot throbbed, but he held it down, not wanting to come too quick. He pushed deeper, gripping pale hip as it felt like he was sinking into a melting butter. It was soft and wet and smooth and so hot he saw white for a couple seconds. He was half way in when he stumbled because of another clench, and he accidentally tugged on the long tail. 

Katsuki squealed.

His body shook, convulsing, and his pussy gushed with hot slick. Half out of his mind from intense pulsing on his cock, Eijirou pushed all the way in one smooth thrust. He felt like he was punched in the guts as he leaned over Katsuki. His legs felt like jelly, and he heaved for breath. Distantly he heard small whimpers of overwhelmed hybrid, but at the moment all he could think about was to come.

To knot tight pussy so it would squirt again. It felt heavenly.

He rocked in tight heat, grunting from how hard his cock was squeezed. Katsuki seemed strangely quiet, and when Kirishima turned to face him, he realized that the boy was knocked out. His face was wet with tears; his nose and cheeks were red with blush as he breathed softly, passed out.

Jesus Christ.

His pussy loosened after a couple hard thrusts, and Eijirou pushed his limp body higher on the bed. He slipped out, turning the boy around. His puffy nipples were soft under his touch as he pressed between open legs. His cock slid in smoothly. Squelching mess of hybrid's cunt was a bliss, and alpha snarled watching perky tits bounce with his every thrust. His balls were slapping on the boy's ass loudly with his every slam. Sweat was rolling off his shoulders as he chased his orgasm. The boy under him was pliant. Soft cunt was taking him well, stretching at the push of his swelling knot.

His balls ached for release when Katsuki let out a small whine, and his eyes opened slowly. His breath quickened, and then sharp claws sank into Eijirou's shoulders as strong legs trapped him in a lock. He snarled, feeling sparks of pleasure shooting up his spine, and started to pound into tightened heat.

"You little shit—Oh, fuck! Fuck! Yeah, tightened up... Come on—Little slut, come on..."

Katsuki looked at him with wide teary eyes, whining. He was drooling, his fangs nipped on his lips as he kept gasping at hard thrusts, and soon he yowled again. His pussy clenched so tight, Eijirou thought his dick was about to snap off. Feeling hot slick rushing past clenching greedy hole, he kept pushing, and with another couple thrusts, he shoved his knot in, coming.

It seemed to last for hours.

He heaved, slumping on the boy and squishing him with his weight, but he couldn't move. Holy crap, it was incredible. The wave of orgasm seemed to swallow him whole, rolling through his body and spreading deep into his bones. It's been a while since he got laid, but this was something phenomenal. Deep scratches bled and stung, but it was only adding to his bliss as he felt his whole body sagging in pleasant tiredness. His knot pulsed inside, emptying his balls, and he sighed, satisfied.

But a hard bite on his chest made him wince, and he pulled up.

Katsuki was growling at him, baring his teeth. To that, Kirishima rocked into his ruined pussy, and immediately, thin brows flew up in needy expression, making alpha grin.

"That's right, you little shit. Behave."

The boy let out a soft keen as if begging and pushed his hips up, fucking himself on alpha's knot. His sloshing mess of a cunt was practically sucking on Eijirou's knot, like an eager mouth would, milking him for all he was worth. Auburn eyes were teary, with dilated dark pupils, and Kirishima caressed his cheek, anticipating another bite. But instead, Katsuki nuzzled, purring and looking at him with half-lidded eyes.

"You little demon. Gonna make me soft with these eyes of yours, mm?"

He scratched the boy under his chin, earning an eager lick of the tongue on his palm. When Kirishima turned them around, still tied, Katsuki purred loudly. Reaching up and nuzzling his neck and chest, he chuffed, satisfied and pleased. His hips started rocking back and forth, tugging on still swollen knot and making alpha flinch in oversensitivity.

"Hold on, you little slut—"

The boy had the nerve to whine and looked at him with a pout on his full lips. His claws pushed into alpha's chest as if threatening to sink in if he didn't do anything. To that, Kirishima sneaked his hand behind the boy and rubbed on the base of his tail, tugging. Growling and whining, Katsuki flopped on his chest, weak for it and wiggling his butt for more, and alpha spanked the eager boy.

"Behave, you brat."

Katsuki sighed and looked him in the eye with a small pout like a petulant child. Kirishima cooed, melting from his adorable face, and scratched the boy behind his round ear, watching glowing eyes turn into moon crescents in pleasure.

"Who knew you can be cute like this, mm?"

The boy only purred, budding his head into his hand for more.

After all, the rumors turned out to be true.

Kirishima did tame a monster.

His golden kitten.
