Bakudeku A/B/O Prompt, soft, fantasy AU NSFW @bkdkkinktober

As soon as the omegan slave was pulled around the corner, Katsuki knew that was the one he wanted. The lithe little green-headed male being dragged onto the stage had the most alluring scent the alpha had ever smelled— A surge of anger washed over him that this beautiful omega was being treated in such a degrading manner. Disheveled rags adorning its body, and it was clear they weren’t feeding him enough. He had to have him, or there’d be hell to pay! Katsuki let out the loudest reverberating growl to silence the other alphas in the room, and once they’d moved out of his way, he sauntered up to the stage, crooning in softer tones to soothe this raggedly clad welp of a creature.

The omega answered— whimpered, purred, and twisted in his chains for Katsuki. The alphas song called to him in a way no other had before— Someone to care for him, who wanted him, wooing him in a mating call that brought a sense of peace and safety to his meager existence. And Katsuki was a prime example of an alpha of the rarest kind. His prayers had finally been answered.

Katsuki preened at the omegas acceptance and tossed a satchel of gold to the slaver. “NOW GET HIM OUT OF THOSE CHAINS!” He demanded with a growl that promised pain if not catered to.

Once free of his bindings, the omega ran into the waiting arms of his new alpha, mewling and purring with moisture pooling in his emerald eyes. Katsuki scooped up the welp and cradled him close as they left the building, returning soothing pheromones that spoke of a better life to come. The omega cuddled to his alphas chest and wrapped his arms around his neck, closing his eyes and sighing happily.

“Tell me your name,” Katsuki gently commanded.

The omega paused, flinched as if not sure how to respond correctly, too broken by the slaver’s harsh treatment. It pulled at Katsuki’s soul.

“It’s okay,” Katsuki released a stronger pheromone to calm the omega further. “You can speak. No one will hurt you ever again.” It pained the alpha at how light the man was in his arms.

In a soft tone, the omega finally answered. “Izuku.”

Katsuki grunted his approval. “I am Katsuki of the Bakugou tribe.”

“Ka… Kat… Kacchan…”

The alpha chuckled. “I’ll allow that name.”

It took two days of heavy riding on horseback to reach Katsuki’s home at the base of a mountain. The village itself was moderately sized, and most of the men and women bred of hearty stock, so Izuku was different. But the alpha didn’t care. He wanted a mate that would stir his loins and hold his attention forever, which Izuku’s scent promised both.

“You’ll give me such beautiful pups,” Katsuki cooed to his emerald-eyed omega as they cuddled in their new nest. “But after I put some meat back on your bones first.” Izuku was very thin with barely any padding on his body, lacking the breadth of childbearing hips believed to ensure a successful litter. He was certain that once brought back to full vigor, this omega would do just nicely considering a simple bath and proper clothing had already done wonders.

The omega whimpered, embarrassed from his frail state. “Sorry, I’m not ready for you.”

“Don’t,” Katsuki responded softly. “It’s not your fault.” If it was anyone’s fault it was the slavers. “Tell me, how did they take you?”

Again, Izuku whined with distressed undertones leaching in. “They stole me from my home two years ago— said I was too beautiful to pass up… but no one wanted me o-or liked how I smell, so they beat and starved me…”

The waves of sorrow mixed into the omegas scent caused Katsuki to growl low and pull Izuku tightly against his body. “I’m so sorry they did that to you. But that’s over now. You’re mine now.”

“I just hope my mother is okay,” Izuku sighed and curled against the man’s chest.

“Tell me the village, and I will send for her.”

Izuku raised up in surprise, his teary eyes glistening with hope. “Y-You’d do that for me, Kacchan?”

“Of course,” Katsuki smiled, cupped, and smoothed his thumb over his mate’s cheek. “It would be good for you to have her here during your whelping.”

“Thank you!” The omega threw himself back onto the alpha, kissing him all over his face. “You make me so happy Kacchan!”

A low, rumbling vibrato emanated from Katsuki in pride to have such a contented mate. He never understood why many alphas treated their omegas like slaves. To him, they were an important part of the pride— nay more important than alphas because without them, lineages would die. “Mmm,” he crooned against the scent gland at the base of Izuku’s neck, giving a few licks and nips to bloom its scent. Kissing lightly along his neck, between each word. “You make me very, very happy too, mouse.”

“Kacchan…” Izuku purred as the alpha wrapped his arms around and maneuvered him beneath into the downy bedding. Katsuki’s large frame engulfed his smaller body, but the male was careful never to suffocate or crush. It wasn’t their first time… and while he still couldn’t handle the alphas knot, they made do with Katsuki’s seemingly endless stamina. Who knew the brawny male could be so tender, with gentle guiding and long, slow strokes of his cock while smothering with kisses. The alpha explored and pampered Izuku, paying attention to every little detail— overstimulating his body and mind until all he could do was writhe in ecstasy.

With each day that passed, Izuku’s strength grew, and his body slowly began to look healthier. While Katsuki dealt with other matters, he focused on being a good housemate, cleaning and tending to a garden, cooking, sewing, or doing whatever was necessary. Those lonely, tortured years quickly melted away from the loving support his alpha provided, so Izuku wanted to do everything he could to return that love— most of all, starting the family they both desired. Days turned into weeks, and soon enough, Izuku could preen with pride at the hourglass curves in his reflection.

“Mmm,” Katsuki placed his hands on his mate’s new voluptuous hips when he caught him looking into the mirror. “I knew I was right about you,” he patted the omegas back side. “Filled in nicely.”

Izuku giggled and spun around in the alphas grasp, throwing his arms around Katsuki’s neck, to which the alpha responded and picked him up. “I feel like my old self again,” he beamed and purred against the larger male’s chest, burrowing his nose in his mate’s scent gland. “All thanks to you, Kacchan.”

Katsuki crooned back with a heady low growl, taking in the omegas heightened scent of arousal. “Looks like it’s time I put some pups in ya, whatd’ya say?”

“Yes…” Izuku purred.

The alpha placed the omega gently into the nest, giving him time to settle into the soft bedding. As Katsuki stripped away his clothing, Izuku too removed his dressings along with the pins holding down his wavy shoulder length hair, allowing it to fan out over the pillow. His fair skin glowed from the sunlight and contrasted against the darker hues of the nest, with the only other coloring a thatch of green between his legs, loosely spread and ready.

“So beautiful…” Katsuki crooned at the sight as he gently lowered himself over the omega and nestled himself between the man’s thighs. “Smell so good too…” the omegas bloom ripening and mixing with his own like an earthy garden of their very own. A hand settled on one hip to control, while the other reached up to caress and stroke Izuku’s cheek, lovingly thumbing the smooth skin as he coveted his lips.

Izuku wove his hands into the alpha’s hair, threading through with gentle glides as he mewled and purred in a show of affectionate appreciation. Their bodies slowly wound and ground, rubbing against each other’s to kick up their release of pheromones into the room, and heightening the euphoric sensation it brought a mating pair. The slick building between the omega’s legs beckoned for use, but Katsuki was always invested in pampering his mate first. “Kacchan…” the name moaned out from the licks and suckling the alpha placed all around the omegas neck and upper body, teasing his sensitive nipples and sending his mind reeling. His biological clock was ticking, knowing its time had come, and while Izuku appreciated the care, he’d waited so long for this moment that all his mind and body wanted was the fulfilling consummation. So, the omega ground his hips and cinched his legs, rubbing against the alpha to release the ache of his heat and firmly present his desire.

Katsuki chuckled at Izuku’s impatience, but obliged, shifting their bodies to slip between the folds until he could go no further. The snug fit brought a purr from the omega and a wave of pride for the alpha. “So, perfect…” he crooned while coveting his mate’s lips and rocking his hips in a slow piston motion to savor the fulfilling heat levied on his cock. In and out, Katsuki thrust as their bodies writhed against and moved in time with each other’s. Izuku followed, back flexing and arching, his hips shifting to ensure the deepest reaches, all the while mewling and pawing at his alpha in wild delight.

“Faster, Kacchan,” the omega whimpered as the pressure of his alphas inflating knot pressed into his heated channel. Izuku knew his mate was close— so was he.

“It… doesn’t hurt, right?” Katsuki panted out to make sure.

“No…” Izuku groaned. His body was ready.

His rutting scent mixed with Izuku’s heat grew stronger by the second, even his fangs elongated in preparation. So, Katsuki gripped down and held firmly to his omegas hip points and increased the pace of his thrusts for a few more reps until the knot forced him to concede and bite down onto Izuku’s mark with a reverberating growl. Katsuki’s body shook lightly as his seed emptied into his mate, his hips jerkily grinding to milk every bit of his cock. The long-awaited release was everything his alpha heart could have hoped for.

Izuku whimpered and moaned from all the stimulation levied on his body. His mates bite further released a strong, soothing pheromone to relax him so the alphas seed would take stronger root. Once Katsuki released his bite, he wrapped his arms around his mate and buried his face in the alphas neck, purring with content at the prospect of starting a family. “I love you so much, Kacchan.”

“I love you too, mouse.”

Prompt- Brat/Manhandling plus some aftercare w/ABO underpinnings @bkdkkinktober

“Ka—cchan…” Izuku groped harder at the tent pitching on his boyfriend’s crotch— thanks to him.

“Quit it!” Katsuki swatted at his hands. “You’re gonna make me crash!”

“Mmm— No.”

“If I have to pull over, you won’t be able to walk for a week.”

“Promise?”

“Oooh, you naughty little brat! Where the hell did this side come from all of a sudden?!”

Shrugging and shifting nervously in the passenger seat. “I don’t know…” Izuku whined.

Katsuki narrowed his eyes as he took a good whiff. “You forgot to take your heat suppressors again.”

“Maybe….”

The alpha growled and gripped to the steering wheel. Fucking hell, he didn’t have condoms in the car, but if his omega partner kept this up, he wouldn’t be able to control himself. Katsuki saw a gas station a block away, and immediately pulled in. “Hurry up and get condoms,” he commanded.

With a giggling squeal, Izuku raced inside, quickly purchasing a box before jumping back into the car. “Gimme, gimme, gimme!” He tried to unbuckle the alphas seat belt while fiddling with the man’s belt.

“Oi! Not here you minx!” Katsuki slapped the back of his mate’s hand. “I ain’t sharing that ass with the public!”

Tears pooled in Izuku’s eyes. He sniffled and pouted, whining louder. “But Kacchan…”

“No!” The alpha snapped, flooring it back onto the road. He needed to find a more private spot and yes, he’ll damn well punish the little brat for this mistake. Izuku just had to pull this stunt when they were still about twenty miles from home in the next town over.

Searching along the highway which cut through a forest, Katsuki knew there’d be side roads eventually and if his recollection was any good, there was one that should suffice. The achy pressure of his cock straining against his jeans, coupled with the pungent savor gathering in the enclosed space grew annoying the longer it took. Izuku whined the entire five miles, pawing at his crotch and pants, and eventually, the alpha let him unzip them, but kept the omega from grabbing his dick.

Finally, Katsuki pulled down a pitch black, two-lane dirt road lined narrowly with trees. He drove several yards in until a bend in the road would give them a blind spot from the highway, and stopped the vehicle, turning off the headlights, while leaving the dome light on inside the car. The alpha walked around and pulled the omega out of the car roughly by the scruff of the neck.

“Is this what you wanted,” Katsuki growled low next to Izuku’s ear as he pressed the omega chest-first against the trunk of the car.

“Yes,” the omega hissed as he pushed and rubbed his ass forcefully against the alpha’s crotch. “I need…” Izuku handed the box of condoms over his shoulder, then wiggled his bottoms off until they pooled around his ankles. “Give it to me!” He demanded.

Katsuki slapped Izuku’s bared ass hard, rubbed, then smacked it again to the omega’s light cries and whimpers. “Naughty, naughty brat.” He ripped open the wrapper and rolled the condom onto his rock-hard cock. Their marriage was right around the corner, and he wouldn’t need to use these if his damn mate could stay true to the suppressors schedule. He swore Izuku did it to drive him crazy.

Reaching down between the omega’s legs, Katsuki ran his fingers over the man’s cocklet, down further over his moist opening already dripping with slick. “Damn, Izu, that bad huh?”

“Mmm, hmmm,” he mewled at the alphas touch.

“Then take the damn meds like you’re supposed to brat!”

“But then you don’t fuck me as much as I want,” Izuku retorted.

“Like this?” Katsuki rubbed the tip of his cock against his mates opening in a teasing fashion.

“Yes…”

“All you gotta do is ask—” Katsuki pushed just the head through to gain a sigh. “But you know I prefer bareback.”

“I know…”

Katsuki pulled out again, chuckling when Izuku growled at him for it. “Will you be good from now on and take the suppressors?”

“Yes,” the omega whined. “Please,” he begged, “don’t tease me!”

“I’m holding you to that promise,” Katsuki spat as he rammed his cock in.

Izuku cried out with a high mewling moan. “I promise! I promise!” Pushing back with his hips too, begging for more.

Katsuki slapped the omegas ass. “Behave!” Then gripped forcefully onto the man’s hips for control, rocking his cock in a piston motion nice and deep into Izuku at a measured pace. The omegas hands flailed and grabbed onto the edges of the trunk as the alpha railed him again and again. Once Izuku was busy holding on for dear life, the alpha let go with one hand to toy with his omegas cocklet, squeezing and rubbing out the appendage to pull more mewls and purrs from the man.

“That’s a good boy,” Katsuki crooned, leaned over with lips and tongue teasing Izuku’s neck and the mate mark at its nape to pull more of his delicious pheromones out. He always loved his mate’s earthy scents, mixed with his own smoky spice. The crisp clean air of the forest made all the cleaner and more divine. His hips pace was relentless on the omega. The man wanted to be fucked, well, that’s what he was gonna get as he pounded into his hole so roughly, Izuku’s feet couldn’t stay planted to the ground.

The omegas cries echoed out into the darkness and were swallowed by the forest as he panted for dear life at the mercy of his alpha. It’s what he wanted— Katsuki’s cock pummeling him, claiming, and declaring him his one and only. A cacophony of grunts and moans, higher pitched mewls, to the slapping sounds of skin on skin testing the alphas ripening cock. “Mmm, Kacchan…” Izuku purred as he felt the pressure rising and his own orgasm brought waves of succulent heat, splattering the poor cars bumper.

“You’re on… car wash duty… for this…” the alpha shaky voice panted.

All the driving movements shortened their pace as Katsuki’s knot expanded and locked him into place. He yanked Izuku’s head up by the hair, arching the man’s back, then quickly biting the mark on the omegas neck. Izuku screamed and braced himself in the awkward pose while the alpha finished him off, slamming his hips so roughly he was bound to have bruises left by the metal car.

“Fuck,” Katsuki growl groaned as the last heated pulse left his body drained and he detached his fangs from the omegas throat, licking up the few droplets of blood before dropping and pining the man against the car while he caught his breath. “Damn brat.” He panted out. “Happy now?”

“Very,” the omega purred and wiggled his sore rear.

“Oi!” He spanked Izuku again. “Enough!”

It took a couple minutes for the knot to deflate before Katsuki could finally pull out, tugging the filled condom off and tossing it aside. He turned Izuku around, keeping him pressed against the car as he finished cleaning his mates mark with tender licks. “Such a horny little brat,” he chuckled.

“I can’t help it,” the omega pawed at his mate, purring up a storm. “Kacchan is just so… good… I can’t get enough.”

“Yeah, yeah, ya little minx,” the alpha growled though with no malice in his tone. “Let’s get you home and cleaned up. You’ll probably be sore in the morning.”

“Will you give me a bath?” Izuku batted his lashes with sparkling and hopeful wide eyes.

Katsuki kissed his omega softly, crooning. “I’ll always take care of my bratty little baby.”
