Work Text:

This was the tenth facility Bakugou entered in his search for a good hybrid. Man-beasts, half breeds, hybrids as they are more synonymously referred to now, come in a variety of combinations. Many of them resemble common domesticated animals with a few presenting more wild, often exotic traits.

Bakugou was not picky. He just has not found any hybrid that could match his tenacity. Sure there were some adorable domestic shorthair cat hybrids at the seventh facility, and that cute shiba hybrid in the last one, but none seemed able to keep up with him. He did not need a lap hybrid, or a bed warmer. He needs a loyal partner. Bakugou wanted a hybrid that can be its own independent person while also proud to be mated to an owner like Bakugou.

An alpha would be perfect. They’re protective and fiercely loyal to their owners. That’s not to say Bakugou wants a guard dog, no, he wants a hybrid that can stand up to him like a good partner. And an alpha’s knot was a persuasive selling point. If only he could find one. All of these breeders kept their precious alphas guarded, the few that they had. Hopefully this smaller establishment was different.

“An alpha, huh?” said the clerk for clarification. They stood up from their crouching by the shelves as they mulled over the question, mentally checking their stock. “Well!” she said with a joyous clap of their hands, “There’s two available, let me show you!”

They seemed especially cheerful over this opportunity. With practiced ease, they pulled a keyring out from their apron’s pocket and shimmied past the clutter of boxes with pet toys and hybrid accessories they were in the middle of stocking.

Bakugou had to ask. “You seem a bit eager to get rid of these two.”

“We all are, honestly,” she laughed at the frown Bakugou made. “It’s nothing like that. They just have been passed over so often, we’re getting worried for their future.”

“Sounds like they’re menaces.” Bakugou caught a whiff of the tell-tale scent of animal. The feed, the toys covered in strange enticing smells. But it smelled clean, almost hospital-like.

“These two are rowdy,” she said, stopping at a door with a small window, “but they’re complete babies. All they care about is rough housing and eating. Very food driven.” She then opened the door. Her whole body was pressed against the sliver of space between the rest of the shop and inside the hybrid pen, one leg behind her braced like a quarterback ready to be slammed into the floor after launching their ball.

Bakugou was going to demand why this was a necessity when claws scraping across soft flooring turned into a rumbling stampede that ended with the door smashed open. There was no time for him to brace. The clerk disappeared under a mass of silver fur but Bakugou went blind. It became warm. His vision was completely filled by dark red fur and a hulking hybrid panting centimeters away from his face. Drool managed to drip on him but he didn’t have a chance to be upset before a tongue slobbered him from chin to eyeball and then dipped right into his mouth to then drag up to his nose.

“Kirishima, off!”

Fully violated by dog drool, Bakugou sat up when the red hybrid was yanked away from him. To his merciful surprise, the clerk had both hybrids scruffed and sat them on their haunches. The mutts had the audacity to look saddened and whimper at not being able to assault them anymore. Although they could very easily decide to overpower them both, that got Bakugou’s interest peaked. And his pants got a bit tighter at the prospect.

“Sorry!” said both mutts in a very loud outdoor voice. Hybrids could learn human language but it was more of a parroting. Commands and simple sentences were what they could manage. Their tails, Bakugou noticed, never ceased wagging and smacking the clerk’s ankles. Seems like the padded boots were a choice made from experience.

“This is Tetsutetsu Tetsutetsu,” she introduced by tugging at the scruff of the silver coated hybrid, “and Kirishima Eijirou.” Kirishima, the red coat, barked after his introduction. Tetsutetsu, both sur and given name apparently, shimmied on his haunches. Both of them were obviously energetic, but Tetsutetsu seemed the most prone to acting out.

The clerk continued. “You’re welcome to inspect them. Their teeth are healthy, coats and skin perfectly smooth. Neither have had their ruts yet, so still in the process of presenting but you can observe their developing knots for yourself. We have a backroom in the pens for just that, but purely for inspection. We’re not a licensed hybrid pleasure house, y’know?”

He glanced at them and saw some of the biggest balls he has ever seen on any man or hybrid. A sheath kept their cocks hidden.

“Are those full?” Bakugou gestured by lightly tapping Kirishima’s hanging balls with the point of his sneaker. Kirishima only tilted his head, not understanding the intricacies of what Bakugou had planned for him. Tetsutetsu whined, a guttural pitch that made you want to ruffle his ears and the mane of silver hair.

“Again, you’re welcome to spend some time with them to appraise and see if you’re compatible. But there is a catch,” the clerk said, “these two are a bonded pair. We can adopt them together, or not at all.”

“Is that so?” It made sense why these two were being passed over so often now. One large hybrid was a hassle. Two hybrids that looked to have wolf traits, and could body check you like a rugby player by accident, were the perfect specimens if you wanted some broken furniture, or bones.

She scratched at the hybrids’ ears, Tetsutetsu’s had a notch in one of them while Kirishima closed his eyes in pleasure to reveal that one was scarred. “They were dropped off to us in a miserable state. Thankfully they needed more love than medicine or surgery to get healthy. And a lot of food.”

“They gave me a lot of meat!” Kirishima chimed in. Tetsutetsu nodded.

“What kind of meat?” Bakugou could already feel himself warming up to these bundles of fur and muscles.

“Tasty meat!” answered Tetsutetsu.

“Very food motivated,” agreed Bakugou with the clerk that seemed genuinely amused by their shenanigans. They were obviously under great care. “I’ll check them out in the back then. That’s good with you?”

“Of course, sir!” She led him to a pen that was much like a large silent booth.

The two hybrids followed him inside, barking in answer to the clerk telling them to behave. There were various forms of seating, soft chairs, firm couches, and furniture that looked like cubes and other funky stools. It looked like a play pen.

“Alright, Kirishima, Tetsutetsu, how’re y’feeling?”

“Good!” they both answered with wagging tails. Kirishima continued, “We’re always manly. Never bad, on purpose.”

When Bakugou hummed in question Tetsutetsu spoke.

“Sometimes we knock down the staff.”

“Tetsutetsu mostly.”

“Hey!” The silver hybrid jumped onto Kirishiam who growled in answer. They immediately began to roll around locked into grapples when finally Kirishima managed to pin Tetsutetsu down. But they were already laughing and licking at each other, their squabble settled in less than five seconds without an ounce of malice.

“Well, you two are energetic. What makes you think you can keep up with me?”

“We love a challenge! We wouldn’t be manly if we didn’t try,” Kirishima had a confident gleam in his eye. His bonded pair was much more lax in this regard, seemingly going with whatever interested him.

Bakugou found himself loving these two oafs. They were happy-go-lucky, determined to enjoy themselves, and strong. Tetsutetsu showed off his strength by lifting Kirishima up over his shoulders like a powerlifter. And Kirishima already demonstrated he could pin Tetsutetsu with practiced ease.

Some more talking and Bakugou got to check their equipment for breeding. Afterall, hybrids were great partners in bed and often needed to release to be healthy, especially during ruts and heats.

Kirishima seemed to be slightly larger, his balls large and plump, heavy in his palms. They stayed close to his sheath, tight but soft to the touch. Tetsutetsu’s hung more. While slightly smaller, they felt just as heavy. Bakugou massaged them, soft strokes with his fingers and palm until Tetsutetsu started to rise from his sheath. Precum started to leak from his tip and had his cock shiny as it extended. The shaft was slightly darker than the rest of his skin tone.

“That’s a good boy,” said Bakugou. He rubbed Tetsutetsu’s tummy while stroking the hybrid's cock. Then he massaged the base of his shaft where a pre-rut knot was doing its best to form. Tetsutetsu even gave a few thrusts of the hips without knowing what exactly he was trying to achieve. Kirishima spent his last reserve of patience. Now he went in to press his face at Tetsutetsu’s genitals and Bakugou’s hands, wanting to observe what exactly his friend was doing. Sniffing at the clear pre coming from his cock, Kirishima stuck his tongue out to lick, dragging the wet muscle from shaft to tip and earning a moan from Tetsutetsu.

“Does that taste good, Kirishima?”

The hybrid gave a few more licks, long drags of his tongue, and tilted his head to ponder.

“It’s salty. Can I have more?” He asked with a giant smile.

“Sure, but later. We have to check yours too. Sit down.”

Kirishima did as told. Now Bakugou had easy access to massage his balls and pull on them. He prodded into his sheath to tease the head starting to expose itself. Kirishima was much more vocal than Tetsutetsu, moaning and whining at the ministrations. His cock was thicker than Tetsutetsu’s, darker, and throbbed with his heartbeat. And he leaked even more precum than the other hybrid. It was Tetsutetsu’s turn to prod at his friend’s cock, but he wrapped his fingers around it and sniffed before doing small kitten licks on his tip. He dived in, trying his best to get as much from the leaking slit as he could, basically trying to sound Kirishima with his tongue.

“Alright, let him go, you fiending mutt,” said Bakugou. He offered some pets to the hybrid’s head which they gladly enjoyed. Kirishima whined but some tummy scratches calmed him down. “What do you two say about coming home with me?”

“Yes,” was the resounding answer along with a tackle and slobbering kisses.

 

*******

Taking care of two giant hybrids was a challenge initially. The two were not used to an actual home or the freedoms and responsibilities that came with it. But they were eager learners. Kirishima loved to help in the kitchen, sneaking bites of food for himself and Tetsutetsu. The silver hybrid enjoys learning how to garden and maintain the backyard for the two hybrids to enjoy and play in.

They both got over their fear of the ice machine too. Kirishima almost tore the fridge out while Tetsutetsu flipped the couch to hide under.

Bakugou would not trade his new life for anything. He adored his hybrids and loved having them in his upsized bed keeping him warm and cuddled. Seeing them after a hard day at work was especially therapeutic and they loved to chat about what they got to do. Bakugou trusts them to explore the neighborhood and run errands much to their enjoyment.

But now Bakugou walked into a quiet home. His home should never be silent. There should be two alphas at the ready, barking and tackling their way to reach him. Kirishima already shattered a bookshelf. Tetsutetsu knocked over a painting. Bakugou did his best to hybrid proof the house and its furniture to avoid the same accidents.

So where were his bestest, goodest, hybrids?

His couch was a mix of stuffing and wet patches. Kirishima has always made sure the two of them were following house training rules. One sniff was enough to realize it wasn’t urine, but something much headier. Precum.

From his room came sounds like roughhousing and growling. They were chuffs and high pitched whines that had Bakugou running to burst past the half shut door.

Kirishima was on top of Tetsutetsu, the both of them above a layer of clothes and Bakugou’s bedsheets with the hybrids’ own blankets and pillows made into a haphazard nest. Two alphas did not have the natural instinct to build a proper one, but they did feel as if they needed some type of designated alcove to breed. Their den happened to be Bakugou’s bedroom; more accurately, they saw Bakugou as the alpha and sought his den for comfort.

Tetsutetsu was barely visible on his chest and knees, face pressed into the sheets by powerful arms coated in a sheen of sweat and red fur. Kirishima mounted him, his hips thrusting but always missing the mark. Bakugou stood back to watch for a moment, enjoying how his hybrids were frotting, Kirishima using Tetsutetsu to basically masturbate. The red hybrid’s back flexed in the dim light that managed to pierce the drawn curtains. His muscles bulged and strained, shaking with every curve, arch of his back and hips. The dimples of his ass appeared and softened, muscle and fat bouncing with every thrust. Kirishima’s tail was held up stiffly in a way that showed he was hyper focused on the task.

He got closer to observe the large cock dripping and gliding between ass cheeks and sometimes prodding at Tetsutetsu’s balls. It seems like both haven’t been able to cum. But their knots looked aching to properly form.

“What’s wrong boys?” Bakugou said, placing a hand to calmly stroke up and down Kirishima’s hamstring. He dipped in to fondle at his balls and poke at his perineum before going back to massage the powerful muscle that spasmed with the need to fuck into a hole.

“Katsuki,” both hybrids whined. Tetsutetsu tried to lift himself but Kirishima snarled before latching his teeth into his shoulder and keeping him pinned. He gave a hard thrust.

“Hey, don’t be mean to your rut mate,” Bakugou gave him a light spank.

“Not my mate! You!”

“Yeah, you! Katsuki!” Tetsutetsu agreed with Kirishima even when he was currently one lucky shot at being mounted and bred.

“We’re all mates, dummies. Look,” Bakugou reached underneath Tetsutetsu to hold the thick cock that throbbed with every beat of his heart, “you’re hard because of Eiji, aren’t you?” He tugged hard and Tetsutetsu humped into his fist, precum making the hole slippery and warm.

Kirishima whined but he started to lick at the indents his teeth left behind. For all of the alpha’s bravado, he did his best to not ever hurt Tetsutetsu, let alone break skin with his teeth. He was a good boy.

“That’s good, Eiji, you want to feel good and make Tetsu feel good, right?”

“I love you, and Tetsu,” Kirishima started to tear up but Bakugou brought his fingers, slicked in Tetsutetsu’s precum, to his lips.

“Hey there, taste how good you made Tetsu feel? He’s all wet because of you, you did good Eiji, so did you Tetsu,” he managed to trace his nails up and down Tetsutetsu’s side. His muscles were just as powerful as Kirishima’s but he always had a softer layer of fat covering them that made him just the most adorable pudgy hybrid. He was gorgeous bent underneath Kirishima like this, pale skin rosy and rolls of his body being molded by their touch. He needed his hands on every inch of him.

His patience gone, Bakugou had to watch his alphas be ruined by their rut brained need to cum. He took hold of Kirishima's cock and stroked it, once, twice, and pressed his leaking tip to the rim of Tetsutetsu’s pliant hole. It caught. And Kirishima moaned so low that his chest rumbled in a purr before howling as he sunk inch by tight inch into the warmth that was milking his cock. Bakugou fondled his balls as Kirishima settled to the sensation of his cock being swallowed so effortlessly.

His alpha's instincts took over telling him to thrust, to rock his hips and smack against Tetsutetsu's ass to breed him full of cum. His thrusts were wet, loud and fast but never shallow. Kirishima nearly pulled out just to fuck his shaft balls deep and punch at Tetsutetsu's prostate to have him flow precum like a waterfall onto the bed.

Kirishima drove in, clapping thighs against ass with every drag against his cock into massaging heat that began to tug at his forming knot. Bakugou pulled himself away only to return as fast as he could with an uncapped bottle of lube already squirting it onto his fingers. He gave Kirishima a light spank before pressing slender fingers against a hole that flexed with every thrust of hips. It winked at him more clearly when he pulled the cheeks apart, inviting him to toy with it. So he did. Fingers tapped the entrance and breached with some resistance to the first, second, and third knuckle. The grip was strangling, but electric in its heat. Kirishima aborted his thrusts, whining in a confused rut language as he tries to look behind him. Bakugou didn't let him. He gripped at the mane of red and rugged him forwards to press against Tetsutetsu. His finger pulled out and began to fuck him through until his hole learned to stop fighting against the intrusion. When Bakugou easily found the large alpha prostate Kirishima gave in completely, tongue out and panting as the sweet bundle of nerves was fondled from the inside with precise fingers punching in and out of him. With one powerful thrust of his hand, Bakugou forced Kirishima to bury his cock deep inside Tetsutetsu and cum, his knot expanding to lock in place and batter Tetsutetsu's own heat inside him to force him to pop a knot without a wet hole to soothe him. He yelped, agitated at the cold air even if his cock was trapped underneath his stomach releasing jets of cum onto the makeshift nest. Kirishima's cum filled him, another confusing sensation for an alpha meant to breed only to have his stomach bulge with the flow of cream being spent inside.

Bakugou gave him some pity and used his free hand to clamp around the poor knot. His hybrid settled a bit and then groaned as he tried to rut into the pressure, his thrusts lol nothing more than a lazy humping as he remained locked in place with Kirishima. The cock inside him was definitely milking his prostate, just as Bakugou continues massaging Kirishima's with the second finger he managed to fit inside. It was Kirishima's turn to whimper as he kept cumming from his prostate being manipulated to keep his orgasm continuing without rest. He was in the verge of oversensitivity but he couldn't pull out of Tetsutetsu's hole that was milking the knot between his own orgasm and post orgasm torture. Bakugou finally had his two huge alphas a crying and whining mess as they covered each other in their own cum.

He pulled out of Kirishima to open up his pants. His cock was trapped and jumped out into the cool air that made Bakugou hiss. He strokes himself, his cock that was perfectly average but tiny in comparison to his alpha's. Some poured lubed and Bakugou took a step in the mattress to breach Kirishima's hole with the head of his cock. The alpha panicked but Bakugou soothed him as he kept going without mercy, his cock completely sheathed in one movement that had Kirishima moan and fuck into Tetsutetsu on accident. Kirishima's thrusts were fast and hard but Bakugou fucked into him brutally slow with powerful claps that echoed off the walls. He had to show he was their alpha after all. When he was done fucking Kirishima he'd have him clean out Tetsutetsu so he could fill the hybrid with his own cum instead. Their ruts would now be spent with a plug keeping Bakugou's cum trapped inside and their knots milked by him and only him. They're his good boys after all.
