"Katsuki," His sire gruffed, quiet but so powerful with her words. "Come meet your new friend, and don't be a brat," She snorted out, a plume of smoke blowing out of her flared nostrils briefly and making Katsuki squeak as it blew over his face. His second eyelids slid over his eyes as he slithered out from the little sling his sire had him in. Katsuki was careful with his claws as he slithered up her back and settled on her shoulder to stare at the woman and child in front of them.

Katsuki gurgled a little sound as he narrowed his eyes at the small child hiding behind his mother's legs, wide jade eyes staring at Katsuki with emotion the small blond didn't know. Katsuki tilted his head, feeling the warm sun skirt across his flaxen scales. Katsuki could feel the way they shifted on his body as his sire pulled him off her shoulder to cradle him against her chest. He wiggled in annoyance, baring gums spotted with teeth sharp as a razor. "Oh hush, brat," She chided, rubbing the underside of his chin to placate him. Katsuki grunted and slid his sharp eyes back to the little boy who had inched further out from behind his dam to stare at Katsuki and his sire, ducking behind the green-haired woman's long leather and floral-patterned skirt when their eyes connected once more.

"Shy as ever, huh, Izuku?" His sire huffed, leaning down to kneel in front of the woman's legs to be as close to the kid as possible. Katsuki looked up at his sire in shock, knowing the strong dragon-kin woman didn't bow for anyone - and Katsuki certainly did not expect her to bow for a commoner and her pup. "Play nice," His sire warned as he was set on the sun-warmed ground, his talons sinking into the blades and earth. Katsuki chittered as he flexed his paws, pulling them out of the tangling grass blades to shake the dirt from his claws.

"H-Hello," A timid voice spoke out, making Katsuki look up from where he was swiping away at the blades, watching the kid that's been hiding away from him for the past ten minutes or so slowly inch out. Katsuki stared at the pup that was very likely his age, dressed in small scholar-like clothes with a little button-up and khaki shorts. He also had on ugly, weird-looking red shoes.

Katsuki blew steam out of his flared nostrils, looking at the pup in front of him, tail swishing over the flowing grass blades. He could see the pup flinch at every little movement from the little dragon pup, looking awkward and out of place.

Katsuki decided he didn't like him, snapping his jaws and opening them wide. His throat flexed and fill with smoldering embers that raged like a fire out of control before a short blast of fire bloomed from his open mouth. "Uwah!" The pup screamed, tears spilling down his face as he stumbled backward, hiccuping and squealing scared sobs. Katsuki grunted at the wimp that he was supposed to make friends with, ignoring his sire's hissed screams of his name before he was picked up by his nape and glared at.

"Gods, Katsuki, I cannot believe you!" Katsuki grunted and swished his tail, rolling his eyes as he looked back, ignoring his sire's words of rage pointed at him. He found himself looking back at the little boy, who was cradled to his dam's chest, tears being wiped from chubby cheeks that Katsuki wanted to bite. His tongue squirmed in his mouth with the urge to lick those tears away, huffing to himself as he looked away.

Why did his sire always force him to try and make friends with all the wimps?

-

Katsuki stared at the child - Ku... D-..Deekuu? Was that it? - sitting in front of him, looking awkward and even more out of place than he did with their first meeting, sitting on one of the decorative pillows on the ground scattered about Katsuki's tent. Deku's head was tilted down, and his hands were folded in his lap, cheeks flushed with a soft blush.

Katsuki thought he looked like that sticky treat his dam had given him - mochi, was it? It was strawberry flavored.

"U-Uh, I can go if you'd like? Mama wouldn't be mad at me if I went to her," Deku whispered gently, picking at the little tassels on the pillow he sat on, refusing to meet Katsuki's gaze. The flaxen-scaled dragon tilted his head and hopped off the table he had been lying on, enjoying the cool wood against his stomach.

"Eeep-" Deku squeaked when he got up in his face, sniffing at strawberry-red cheeks. Deku smelt of grass and of his dam, Inko-san. Inko-san smelt of sweet pine and honey, and it had clearly rubbed off on Izuku. Deku tried to lean back and get some space between them, but Katsuki only crawled into the small pup's lap to follow him. "U-Uhm?" Deku sniffled out, eyes glazing over with little tears as Katsuki sniffed at his face. "Am... Am I stinky? Mama made me take a bath earlier," Deku hiccuped out, the first tear falling down his face in a wobbly streak. Katsuki watched it fall, tongue pushing out of his mouth and scraping against his teeth, forked tongue flickering in the air. Katsuki needed to lick that tear away; hehad to.

The urge was just too strong. His belly felt weird, and his mind was suddenly cast into a foggy haze as he watched another tear follow messily down Deku's cheek.

Katsuki grunted when Deku fell back, unable to hold himself in the angle he was for any longer, hitting the soft pelt-covered floor with a little grunt. Katsuki followed him and grumbled gently, big paws framing Deku's heaving chest as he leaned down. He stared into Deku's eyes for a moment, tongue flopping uselessly out of his half-open muzzle, a bead of drool starting to trail down the limp muscle. "Ka... Kachuki...?" Deku whispered out, mouth fumbling around Katsuki's name as they stared at one another.

Another tear spilled down Deku's face, and Katsuki took the chance to lean down, nose brushing against Deku's little button one before swerving to the left and licking a long stripe up Deku's cheek, catching more falling tears against his rough tongue. "Ack-?! What the heck?" Deku whined out, trying to pull away from him as Katsuki let the taste of Deku's salty tears dance on his tongue. Katsuki's tummy feels as if was filled with butterflies, their wings fluttering against the lining of his tummy as he stumbled back. Katsuki huffed as he pulled his tongue back into his mouth, pointedly ignoring the way Deku called out to him as he stomped over to the other side of his tent. Katsuki hissed at the boy, feeling flushed and dizzy as he found the little hidden entrance into the back of the pile of pillows in this corner. Katsuki slithered in there, the facade of calmness and indifference falling off his face as he stared at the ground, knowing his face would be beet red if he was in his human form.

T-Tch...! Stupid humans and their weird tears!

Katsuki ignored the way Deku called out for him for a moment, a weight settling against the pillows as he suspected Deku to be lying against the pile. He stayed hidden until Inko-san came to collect the huffy boy, who wished to see him before he left.

Katsuki didn't come out, tossing and turning as gently as he could as the feeling in his tummy didn't go away, eyes drifting close as his toes curled tightly.

Katsuki needed to get to the bottom of this weird feeling because it made him feel weak. Like a gurgling baby with no use of its senses. Katsuki wasn't a damn baby, unlike stupid Deku, who cried at anything!

How could stupid Deku affect him this badly?!

-

Izuku had a shameful secret. It was something he didn't even share with his Mama, and he shared all of his secrets with her! He could never keep anything from his Mama, but this, he had to.

Because he had a crush on Kacchan.

N-Not like that was a bad thing! Of course not, Kacchan came from a very handsome family, and Izuku was sure he'd grow up to be a very powerful dragon!

But Kacchan was just that: a dragon.

Not a human boy like Izuku, who was pretty useless when it came to being a human. He didn't have special magic like Mama, who was an amazing witch and apothecary owner. All he had was his pen and notebook and a love for the world.

Izuku knew it was weird and probably ta...taboo? to have a crush on a dragon when he was a human. He didn't know how that would work, and Izuku didn't want to think about it, as every time he did, his tummy got hot, and his face flushed all bright. Izuku knows he shouldn't be thinking about it because it was wrong! He was just a boy like his Mama said, and boys like him didn't have thoughts like these!

Li...Like kissing Kacchan! And, and, uhm! Cuddling together on the dragon's cozy-looking bed, which he had been told not to go near by Kacchan's mom, Mitsuki-san. She had explained it was something special to dragons like Kacchan, and Izuku would need permission to go into it beforehand.

Oh jeez, just thinking about snuggling against Kacchan's soft-scaled belly and sleeping curled up together made his face hot as he smacked his hands over it. He was currently alone in his room - which was a small but beautiful room in the house they were gifted by Mitsuki-san for his Mama's help - as Mama had gone on a little day trip to get ingredients for her orders that she had run out of. So, it was Izuku all alone in the house, alone with his thoughts of kissing Kacchan - who was a dragon! - that made him wiggle from where he was on his bed.

Izuku turned over on his fluttering tummy, pressing his face deep into the soft pillow on his bed and whining into it. His eyes prickled with tears at the thought of being a bad boy for having these thoughts, so he promised himself that he would not tell Mama, no matter what! Even if it made him wiggle in shame at the thought of keeping something from Mama, he had to!

He didn't want to be a bad boy in her eyes! That would make him feel even worse.

He also hoped Kacchan didn't realize he was acting off when they met tomorrow...

"Oi." A voice called out to Izuku as he looked around for the wheat-colored dragon he had been used to meeting in front of the dragon's tent. Izuku squeaked at the voice, startling him as he turned around, finding himself staring at strikingly familiar carmine eyes. "Uh, h-hello?" Izuku whispered, tilting his head as he stared at a boy slightly taller than him standing just a couple of feet away from Izuku and Kacchan's tent. "Hah? The fuck are you so nervous about?" The blond-haired boy sneered, lip lifting in clear annoyance, showing Izuku a row of pearly teeth as well as a few missing.

"D-Do I know you?" Izuku squeaked out when the boy walked closer, reaching out to dig his fingers into Izuku's hair and shake the messed-up curls around. "Of course, you know me! The hell, Deku? Did you mutter yourself into fucking stupidity?" Knuckles rapped against Izuku's temple, making him whine at the pain as he held his forehead. "D-Deku?" Izuku muttered, brows furrowing as he stared back up at the boy in both wonder and confusion.

"Ugh! It's me, Kacchan, you stupid idiot," Kacchan grits out, cheeks flushing a slight pink at the mention of the nickname.

"Ka-Kacchan?!" Izuku squeaks out, hands falling away from his forehead to flop down against his sides in shock. Kacchan, well, Kacchan looks different.

He's human. A boy just like Izuku.

Something inside of Izuku preens, happy to know that his crush can be out of the little box he had shoved it in when it was a shameful secret.

"Yes, idiot," Kacchan huffs and puffs, snapping little teeth at Izuku like he used to do in his dragon form. "I finally managed to unshift... n-not like I was stuck in the first place!" Kacchan suddenly shouts out, gritting his teeth before he shrinks back, turning away to duck into his tent. It's so utterly Kacchan-like that Izuku can now truly confirm that the boy that just ducked into the tent was indeed Kacchan.

"Oi! Stupid Deku, get in here!" Kacchan's loud voice - which Izuku is now getting used to, having been used to only dragon sounds prior to this - echoes from inside the tent, snapping Izuku out of his musings.

-

Katsuki grunts as he looks around, staring far and wide around where his tent had been set up before pulling his head back in. He shuts the tent flaps, and weaves the intricate, one-of-a-kind seal he had been taught to lock the tent close. Katsuki hums and turns to look at Deku, who is lying on the ground, fiddling with his hands, watching him.

Katsuki licks his lips, humming to himself when he flops down next to the smaller boy, staring back at the boy for a moment. "So... what now, Kacchan?" Deku asks after a moment, hands resting on his chest and drumming there idly against his sternum. Katsuki hums, thinking back to the previous plan that makes him shift and his tummy fill with butterflies. "W-Well..." Katsuki stutters out, pulling his lips into a pout as he looks away from Deku. Deku hums and waits for his response, ever the patient little annoyance. "We could... argh!" Katsuki claps his hands over his eyes and scrubs up and down his face before sitting up. He stares at the wide-eyed Deku for a moment before rolling onto the boy. Deku squeaks and goes to sit up, but Katsuki holds him to the floor with a glare, fingers toying with the bottom of Deku's shirt, feeling the warm flesh underneath graze his hands.

Katsuki flings the bottom of Deku's shirt up and ducks into it, grunting as the fabric stretches around his bullying body as Deku squeals. It was just like when Katsuki had been shifted into his dragon form and had done the same thing, bullying his way into warm-blooded Deku's shirt to soak up that warmth.

"K-Kacchan!" Deku squeals, little legs kicking as Katsuki settles there, pinning the wriggling boy down with his weight. "Shut it!" Katsuki hissed against Deku's collarbone, staring at the pale freckled flesh just inches from his mouth.

Katsuki can feel Deku's chest rumble with little giggles as hands fall against Katsuki's back, rubbing up and down the protruding ridges of Katsuki's spine gently. "Ehe... you really are Kacchan," Deku giggles, and Katsuki grunts, tilting his head up to dig his chin into Deku's chest to stare at him through Deku's stretched neck-hone of his shirt. "The hells that supposed to mean, ah?!" Kacchan hisses, offended at the unknown reason why Deku said that.

Was that a bad thing?! The fuck?!

"Exactly what I said! You really are Kacchan! You act like Kacchan; you speak like him! O-Of course, I didn't doubt you, but this just proved it!" Deku fumbles with his words and tries to make sense to the staring blond, who pulls out of the shirt slowly. The shirt falls to lay halfway up Deku's chest, making the blond hum as he settles on Deku's hips. "Mm... ne, Deku. Maybe I can show you more just so you don't doubt me anymore," Katsuki hummed, staring down at Deku, who looked up at him with a wide, curious gaze.

"O-Okay..." He whispered, and Katsuki grinned, instincts rearing their nasty head as he added Deku - the stupid little unpolished jewel - to his hoard.

Deku was his now.

-

"A-Anh..." Deku whimpered, the bottom of his shirt stuffed into his mouth as Katsuki's hands traveled up and down Deku's wet slit. "You're so different from me down here," Katsuki whispered, eyes transfixed on Deku's lower body, hands traveling up that wet slit. Katsuki can see everything thanks to the fact that Deku's wet panties lay hooked in the crease of his shaking legs. Katsuki, just like Deku, was mostly naked. His clothes lay in a messy pile that was mixed with Deku's as well in their haste to undress, with nothing but one sock remaining on his left foot. Katsuki hadn't even allowed Deku to get his shirt off fully, as it lays only around his neck and stuffed into his mouth to keep the boy from making too much noise and alerting anyone.

Katsuki pulls his fingers away, much to Deku's clear annoyance, watching the clear fluid dripping from Deku string between his flexing fingers. He can feel his pupils expanding as the almost non-existent scent of the fluid reaches his nose, tongue lolling out of his mouth as he pulls his fingers into his mouth. Deku squeaks and drops the hem of his shirt from his mouth to stare at him. "K-Kacchan, that's dirty!" Deku squeaks, sniffling a little sound as Katsuki hums around his fingers.

He pulls them free from his swirling tongue to huff out into the arid air of the tent. "Shut it," He slurs, feeling his tongue bulge in his mouth, shifting to that akin to his dragon form. "Wanna see something I learned?" Katsuki coos, pushing Deku's little knobbly knees closer to his chest and pushing his face against Deku's panty-clad slit. "Y..Yuhs," Deku slurs out, hiccuping a little sound as Katsuki's fat dragon tongue lolls out to press and wriggle against the soft, wet fabric. Katsuki presses the curve of his tongue against Deku's clenching slit, feeling it pulse and warm his tongue. Katsuki can taste Deku on his tongue much cleaner now, thanks to the fact his dragon tongue was riddled with hundreds of thousands more tastebuds than his human one.

"S-So...!" Deku squeals softly, pulling his shirt back into his mouth at Katsuki's sharp glare to wet with his drool and muffled wanton sounds. Katsuki pulls back with a puffed breath, tongue too fat to fit into his mouth as he heaves for breath. He finds himself grinning down at Deku as he pulls those panties to the side once more, leaning down to lave over the cute and different slit with his tongue, feeling the sticky wetness cling to his tongue.

Katsuki's lips tug into a big sharp grin as his forked tongue finds Deku's entrance that, leaks that sticky fluid like a leaky well, hooking the forked tip on it before pressing in. Deku clenches on his tongue with each wriggle, shaking under Katsuki's deft and strong hands that grip the undersides of Deku's small thighs. His tongue wriggles in further, pressing deeper with each slide in and out. It has Deku shaking and Katsuki feeling lightheaded as he's suffocated with Deku's sweet musk.

Katsuki's tongue is roughly pushed out suddenly, bunching up in his mouth as Deku's slit clenches down hard, and the boy thrashes, looking as if he was possessed. Katsuki can feel wetness cling to his inner thighs as he watches Deku sob wordlessly. His brows pull together as his tummy floods with heat, gulping down saliva and the sweet liquid dripping off of Katsuki's tongue in heavy gulps. Deku hiccups and sobs roughly, quiet in his keening before he falls limp after thrashing so hard.

Katsuki rests the boys shivering legs down as he watches Deku's flushed face shift to the side, mouth popped open into a pretty little 'o'. Deku's entire body is flushed, and it makes Katsuki shiver before he falls back onto his butt, breathing out slowly as he focuses his mind on reforming his tongue into one that is of his human form and not his dragon form.

Katsuki grunts as his body is sapped of all his energy, flopping forward to rest next to Deku, who stares at him through tear-flooded eyes. He sticks his tongue out at the boy and groans at the weird stickiness clinging to his thighs. His peepee had twitched hard when Deku started to thrash, his body having gone fuzzy for a moment.

"What... what was all that for, Kacchan?" Deku whispered, voice hoarse and eyes fluttering halfway closed. Katsuki hummed, resting his head on a pillow he pulled under his head, thinking about his motivation for what he had just done. "Don't worry your stupid little head about it," Katsuki puffed out, a small plume of smoke blowing from his nostrils. Deku pouted at him but didn't say much after that, rolling over to Katsuki with lazy movements before the boy was squished against his side. Katsuki rolled his eyes and snorted at the boy, turning on his side to allow Deku to scooch against his sweaty torso. He cringed at the way their sweaty skin brushed together as Deku hummed, looking like the cat who had gotten the cream.

"Needy," Katsuki grunted, poking the boy's stomach.

Deku grumbled something unintelligent, wiggling his way out of his shirt and panties to lay nude next to Katsuki. Katsuki raised an eyebrow as the boy nestled into his arm, resting his head there. "Hot..." Deku hiccuped out, voice nothing above a whispered rasp. Katsuki raised his other eyebrow at the boy, who fell asleep slowly, eyeing the pile of clothes before zeroing in on the soiled panties laying at Deku's feet. Katsuki could feel a deep-seated urge settle inside of him to steal Deku's panties.

Katsuki used his foot to grab onto the side of the panties and push them closer to his greedy hands, tilting his head back to stuff the panties against his searching nose. Katsuki felt a sear of something shoot through him as he huffed in the smell, pulling them away after a moment to gently hide them under the pillow he lay on.

Deku didn't have any need for those anymore because they were Katsuki's now.

-

Izuku lay awake in his room long past his bedtime. He had been tucked into bed by his Mama, who was completely unaware of what he and Kacchan had done in the tent just hours earlier.

His face bloomed red, and his body roared with a fire he didn't know how to contain. Izuku turned on his side and whined into the pillow, stuffing his hands down between his legs to press against his core. Izuku squeezed his eyes shut and hiccuped a little sound that made him flush harder. Izuku didn't know what to do with himself, tossing and turning quietly as a warmth unknown to him radiated through him. Kacchan would know what to do; he had, after all, caused this same fire inside of Izuku's tummy hours ago, but the blond wasn't here. He was at his home, and Izuku was at his. They couldn't see each other until tomorrow, but Izuku didn't want to wait till tomorrow, because he feared this fire in his tummy would swallow him whole.

"Ka...cchan," Izuku hiccuped out as he pressed his mouth into his pillow, rutting his hips forward without any knowledge of how to do so properly, biting into the soft fluff as that fire roared on. His mind swirled with all the things Kacchan did to him, made him feel.

It was all too much for Izuku to handle, mouth popping open as his legs crushed his hands between them, stuffing them up against his wet core as he shivered. His blankets rustled and fell to settle around his hips as he blew out a little whimpered sigh.

Izuku shifted and whined as slick wetness clung to his core and made him flush, biting his lip as it reminded him of the state Kacchan had left him in all that's to that big tongue...

Ah, stop thinking about that, Izuku! He whined as he pressed his hands against his face, turning to face the wall as he pulled his covers back up over his body, curling into a little ball on his bed. Izuku cocooned himself in his blankets and sheets and closed his eyes, trying to banish any thoughts of the blond from his mind for the time being. It didn't work, though, lulled to sleep with that handsome face grinning at him in his mind.

Stupid... Stupid Kacchan...

- years later -

"A-Ahye!" Izuku squealed in shock as Kacchan hopped through his bedroom window, grunting as his boot-clad feet hit the floor. "K-Kacchan!" Izuku stared at the big blond teenager in his bedroom, freshly fifteen. The blond was supposed to be staying away from everyone on his sire's orders as he was to present soon.

Izuku should have known Kacchan would have snuck out, probably bored out of his mind all cooped up in his room for when the presentation hit any day now.

"Sup, stupid nerd," Kacchan huffed out, poking his tongue out at Izuku, who glowered at the teen. Kacchan was clad in nothing but baggy pants, boots, and a simple silk shirt that provided enough airflow. Izuku watched the liquid-like fabric flow and flutter with each steady movement Kacchan made. "Ugh, hello..." Izuku huffed, setting his pencil down on his desk and turning in his desk chair to stare at the nonchalant blond. "May I ask why you are here?" Izuku puffed out, watching the bigger teen step forward. "Mm, depends," Kacchan snickered out, snapping his teeth at Izuku before looming over him.

Izuku stared into fluorescent carmine that seemed to grow prettier every time Izuku saw them and got the chance to stare deep into them. Izuku knew he could find himself lost in them easily, dipping into bloody pools of red and wading in it.

"Earth to nerrrd," Kacchan's voice pulled him out of musings and made him hum gently as Kacchan took his cheeks into his big, warm hand. He could feel the indents Kacchan's fingers made in his cheeks as he looked up at the teen. "Wanna run away?"

"Huh?"

Kacchan glared at him and pulled his lips into a frown that Izuku wanted to kiss away, cheeks squished further between Kacchan's fingers. "I mean, run away to that nice field I found a couple of days ago that I told you about, just for today. Can't take another fucking second of being mother-henned over by my dam and sire. I think I'd go mad if they don't fucking leave me alone for twenty minutes," Kacchan grunted out, looking off to the side and glaring at the second window in Izuku's room. "I..." Izuku huffed out, brows pulling together as he stared at the blond for a moment.

He knew, logically, Kacchan should return home and rest for his up-and-coming presentation, as no matter what he'd present as, it'd be hard on his body.

But how could he convince Kacchan of that?

"Oh, yes, Kacchan!" Kacchan mocked him, squishing his lips together to make it seem like he was talking. Izuku raised an eyebrow, wanting to retort that he did not sound like that at all. "Of course, I'll run away with you, I'll follow every word you say, Mr. handsome!" Kacchan cackled at his apparent impression of Izuku, making Izuku pull away and nip at his fingers in retaliation. "Sweet, let's go then," Kacchan returned to his regular voice and pulled Izuku out of his chair and up to his feet. "Wai- huh?!" Izuku squeaked as he was hauled out of his room and made to follow Kacchan, stumbling behind the blond dumbly. "You agreed, Deku, I don't wanna hear it," Kacchan huffed and traveled out to the living room, passing his mom. "T-That was you!" Izuku squealed, trying to dig his feet into the ground, but it was no use against the much stronger teen.

"Bye, Inko-san!" Kacchan called out to his mother, who looked as baffled as Izuku felt as he was dragged out of his house. Izuku dropped his head and begrudgingly followed Kacchan, going willingly now.

-

"Fuuuck," Katsuki huffed as he lay on the blanket he had grabbed on his way out of his house, head resting on his crossed arms. Deku sits next to him, pouting away and scribbling idly in his notebook. It was so fucking hot out on this summer day, but Katsuki didn't regret leaving his house, not wanting to be hovered over for hours on end. He had already put up with it for four days after his birthday, but he couldn't do it anymore. He loved his parents, but they were being way too fucking overbearing; it drove Katsuki fucking mad. He knew they were just worried he'd present out in the open, but Katsuki knew his body and had been told the signs of every sub-gender presenting and what to look out for. It had been fucking hammered into his mind for years. Katsuki was sure if he really tried, he could recite every word his dam and sire had told him about presentation symptoms word-for-word if he truly tried.

Katsuki looked over to Deku, tracing every little knob in the tiny teen's back. They had both long since stripped down to nothing but their underwear due to the blistering heat. The shade from the tree they were lying under was nice, but it didn't help the fact the air felt suffocating and the day was so hot, Katsuki felt dizzy.

Katsuki could feel his cock start to stiffen, staring at the little fading marks surrounding Deku's body that Katsuki had placed there himself, a lazy grin etching itself onto his face. He shifted till he was pressing his face against Deku's side, arm slinging around the boy's waist. "Mm... Deekuu," Katsuki crooned out, staring up at the boy who looked down at him with raised eyebrows. "Huh? Yes, Kacchan?" Deku asked gently, putting his notebook and pencil away in his bag before settling back as Katsuki started to lap at the sticky sweat clinging to Deku's body. "Smells... sweet," Katsuki crooned as his other hand snuck between Deku's thighs, cupping that pretty cunt Katsuki had eaten out too many times to count. He grinned at the little shuffle and press of Deku's cunt against his hand. Katsuki felt dizzy, so much so that he didn't think it was the heat doing this to him anymore.

Katsuki breathed out slowly, twin streams of smoke blowing out at the corners of his mouth. He sat up, looming over the boy and pushing him down slowly. Katsuki crooned out gently to the confused-looking boy as he ground their hips together, mouth popping open at the ice-cold relief that flooded his veins. Groans spilled forth as he felt Deku hiccup a sweet keen that floated in the air. Katsuki could feel his cock shift and pulse against Izuku's clothed cunt, hands digging into the soft blanket they were on. Deku looked up at him with hazed-over eyes and a flushed face. "A-Ah, Kacchan, I don't think-" Deku stuttered out, but Katsuki growled, leaning down to seal his and Deku's lips with a harsh kiss, tongue pressing into Deku's mouth with a fervor that made even him surprised.

Katsuki sucked on Deku's tongue, twisting their tongue around each other as he continued to grind their hips together, feeling their underwear shift against each other's wetly, fabric clinging to them. "A-Anngh-" Deku moaned into his mouth as Katsuki swallowed it up, hissing into the younger teen's mouth. His hips pumped in unsteady shifts and thrusts as he got consumed by lust, scales crawling up the backs of his hands and arms.

Pulling away, Katsuki snorted a sound of rasped lust as he stared down at his tenting cock. "Fuck," He spat out, rocking back onto his heels, raking a hand through his sweat-slick flaxen spikes. "Gotta... nnh-" Katsuki threw his head back as he fisted his cock through his underwear, falling back and sliding his feet out from under him as pleasure ran through him. Katsuki could feel his cock pulse as he jacked it hard, underwear caught in the way, but Katsuki couldn't find it in himself to tear his hand away from his aching cock.

A gentle press of lips against his made Katsuki's eyes slide open as he stared at Deku. Deku's body was flushed a pretty pink, soft nipples pressed against the hard planes of Katsuki's chest. "Pretty," Katsuki hummed against Deku's lips as his free hand fisted Deku's moss curls and tugged the boy in, keenly aware of Deku's hand sliding down to cup his cunt as they kissed. Katsuki hummed and slid his fingers up and down his cock, squeezing and palming the head before fucking the shaft in and out of his shaking hand.

Katsuki pumped his hips and cock steadily, staring at Deku through the cracks in his lashes, gazing at that rapidly flushing face that probably matched his own. He felt hot, dangerous, and raw. His skin felt like it was constantly being brushed by embers that sizzled on his skin. Katsuki pulled Deku away from his lips, listening to that gurgled keen as a sweet smell bloomed in the air, invading Katsuki's nose and making his eyes roll back and his teeth ache. Katsuki fell forward and stuffed his nose into Deku's neck, licking at the skin and hissing against the expanse of Deku's pale neck. "Smells... good, so fucking good-" Katsuki's hips stuttered, and his rhythm broke as he cupped the head of his cock, mouth popping open as cum splattered against his palm.

Katsuki felt dizzy as shit, making him groan and burble bitten-off snarls against Deku's neck as he came down from his orgasm.

"K-Kaaccha..." Deku slurred, wrist shifting as he fingered himself hard, the messy sounds reaching Katsuki's ear. "Nee-d you..! Please, I can't-" Katsuki clicked his tongue and shoved Deku back, making the smaller teen squeak and wriggle. Deku's panties were slid down his soft legs and flung elsewhere, exposing his soft cunt to Katsuki. "Goddamnit, you're dripping, Deku," Katsuki rasped, panting as he took his spunk-covered hand out of his underwear. He used his other hand to hook at the waistband of his boxers and pull them down and off, still-hard cock bobbing in the warm air, dripping a mess of pre-cum and cum.

Katsuki slapped his hand against Izuku's cunt, watching the mess of sticky spunk mix with Deku's slick, feeling the nerd jump at the impact. Katsuki rubbed up and down once, twice, before crooking his fingers to press against Deku's hole and press two in at the same time, feeling Deku quiver around his fingers. Katsuki watched his cum froth around his fingers, and he pushed them in and out of Deku, feeling the boy clench around his fingers, clit brushing against the calloused parts of his palm. "Feels good?" Katsuki chuffed out, cock pulsing from where it was smearing frothy droplets of pre-cum against Deku's shaking thigh. "Y-Yeah...!" Deku sobbed, head thrown back as he came around Katsuki's fingers, pulled so tight Katsuki didn't have to do much to make Deku crest into an orgasm, a moan ripping from his mouth as he writhed. Deku hung off his fingers like he would his cock, shivering and taking him so well as his orgasm ran through him.

"U-Ungh..." Deku whined as Katsuki pulled his slick-covered fingers out, little globs of slick dripping down Deku's asscheeks. "K-Kacchan..." Deku whispered, staring up at him through clumped-together lashes. "Ah?" Katsuki huffed out, jacking his throbbing cock as he shuffled between Deku's legs, resting his cock against Deku's cunt. "I-I think..." Deku huffed out, dragging Katsuki down with a steady grip on the back of his neck, thumbs pressing against the sensitive patches of skin on his throat. "I think we're presenting," Deku hiccuped, moaning as Katsuki's scent bloomed in the area with the help of Deku's thumbs rolling over his aching scent glands.

Katsuki's eyes widened as he hovered over Deku - Omega, Omega, Omega - who stared up at him and continued to gently massage his scent glands, the smell of honey and spiced bourbon and woodsmoke floating around in the air around them. "Ungh, fuck-" Katsuki grit out, hips thrusting forward to rock the underside of his cock against Deku's pudgy clit. Katsuki licked over his protruding canines as his clean hand came to cup the left side of Deku's neck, pressing his thumbs into the swelling patch of skin on Deku's neck. He watched Deku's face slacken, and a mess of slick and squirt hit the blanket and Katsuki's cock as Deku squirted just from having his scent gland teased. "Sensitive," Katsuki purred, breathing that perfect scent of pinewood and honeysuckle. He could also detect an undertone of hibiscus tea - which Deku liked brewing for Katsuki and himself. "Mm... smells perfect, so perfect," Katsuki growled out, swinging his hips back to tease Deku's cunt with his cockhead, breathing out slowly as he pressed in, spearing Deku open on his cock.

"Oh, Alp-ha...!!" Deku squealed, sobbing a sound of relief as his heat was sated by just having an Alpha's cock inside of his sopping cunt. The slide was wet, messy, and fucking perfect. It made Katsuki's eyes itch to roll back and bask in the liquid heat around his cock, sucking him in. Katsuki panted as he started to fuck in, slow rolls of his hips turning into sharp snaps that had Deku shivering in glee, a wobbly smile on pretty lips. "So goddamn tight!" Katsuki snarled out, rutting his hips into Deku's dripping cunt, watching as slick frothed and bubbled around his cock. He was so fucking deep inside of Deku he could see the dent his cock made as it fucked balls-deep inside of his Omega. "Feel that? Right here?" Katsuki gruffed out, pressing his hand to the point where his cock made an indent in Deku's tummy. He marked that spot with his warm fingers pressing into the soft belly that was soon to be fat with his seed, bred like a good bitch.

Ugh, just thinking about Deku being fat with his seed made a ripple of scales break through his skin all the way down his back and disappear, his vertebrae temporarily lengthening to accommodate sharp ridging spines to grow and disappear after a split second.

"Y-Yes! Ah, Kacchan is so deep!" Deku sobbed, little shaking hands coming to press against Katsuki's big fingers that were pushed up and down as he fucked into Deku. Katsuki hummed as Deku's little fingers hugged his wrist as he fucked him, digging into the Alpha's wrist with sharp nails.

"Ka-tch...!" Deku slurred, voice caught in a hitched keen as the first tease of Katsuki's knot kissing his cunt rocked him hard. Katsuki groaned in unison with his Omega as his sensitive knot was exposed to sweltering air. Katsuki licked over his dropped Alphan fangs and lips, tasting the slight iron taste on his tongue. Katsuki could feel something start to bubble deep in his core, pressing at the walls of his core and making him grit his teeth and lean down, stuffing his face into the crook of Deku's neck.

"Please, oh- ungh! Please, please, Kacchan-" Deku begged, sobbing into his shoulder and wetting the skin with his wriggling tongue and tears. "W-What?" Kacchan gruffed out, licking over Deku's scent gland and tasting him on his tongue, which only serves to make Katsuki shiver and throb hard. Deku's cunt squeezed down on him hard as the little Omega gurgled and sobbed open-mouthed, broken words against his shoulder. "Puh- please, Alpha-" Deku keened dangerously sultry and sweet, peeking at Katsuki from the side of his eye. "Knot me, fill me up, do a-anything," Deku squirmed, hips raising to allow Katsuki to press deeper into his Omega, fucking against his cervix, hitting so deep it pressed past Katsuki's marking fingers. "Just, please!" Deku sobbed out, head rolling to the side as he keened a sound of agonized pleasure, mouth popping open as a dribble of drool slid down his chin to meld with tears that fell down Deku's face. Katsuki groaned out as he felt Deku's cunt clamp down around him, so tight it hurt, knot teasing that tight cunt.

Katsuki could feel squirt arch between their messy connection, wetting Katsuki's abdomen and clinging to the very fiber of his being, scent-marking him with Deku's sweet and perfect smell. Katsuki grinned shakily, movements starting to slow down into a sharp, slow thrusting pace that rocked Deku up and down hard. He groaned and puffed out heavy breaths before he nuzzled against Deku's cheek, big tongue lolling out to lick up Deku's sweat and tear-covered cheek. The taste that had made Katsuki obsess over the boy all those years ago burst against his tongue in the form of pretty little crystal droplets. Katsuki moaned a rasping sound as his hips finally started to stutter. He can feel his balls start to cinch tight and his cock throb, head dropping into the pale crook of Deku's neck once more. His tongue and teeth teased Deku's scent gland, scraping over the sensitive skin, just asking for Katsuki to bite down on it and fill it with his venom.

He'd fill the little sac up till it was bursting, just like what he was going to do with Deku's womb.

Deku's fingers dig into Katsuki's back as the Alpha fucks in harder, panting like a goddamn dog, eyes squeezed shut as he feels his knot start to balloon dangerously fast. Katsuki knows his tank is running low, and he's close to finishing as he fucks in and out of Deku's cunt. He can also tell that Deku is very overstimulated by the way sharp but tiny claws rake down his back and how his Omega's body is wracked with shivers.

"A-Ah, oh, Kacchan!" Deku hiccups a bruised sound as Katsuki has to forcefully pull his knot out, gritting his teeth as he stares at Deku's neck. "Please, please, oh god, it felt so good-!" Deku babbles like a broken record, holding his body close to him. "Knot me, knot me, please! C'Can't take it 'nymore-" Deku pleads against Katsuki's sun-warmed skin, pleas sounding oh so perfect to Katsuki's ear, a smirk pulling at the edges of his lips as he cups Deku's cheek with his free hand. He pulls back, back bowing as he pulls his cock out till only the head rests inside of Deku's cunt, lips just inches away from Deku's. "Sound so fucking perfect begging for my knot... I guess I can't refuse my Omega," Katsuki croons, licking a lazy stripe up Deku's cheek before nuzzling against his neck once more, fitting his jaws over Deku's scent gland. "Can't go back now, baby," He grins and shoves in, teeth piercing Deku's scent gland the same second his knot balloons and locks inside of Deku.

The scream that Deku lets out shakes his eardrums and made him hum as he can feel venom exit his fangs and fill Deku's scent gland up. He can feel the little sac balloon satisfyingly, pressing against his lips as he hums. Katsuki can feel his cock pulse with each rope of cum he fucks into Deku slowly, rolling his hips in a never-ending cycle as he drains himself dry with the help of Deku's throbbing cunt massaging his knot.

"Good?" Katsuki huffs gently as he pulls his teeth out of Deku's scent gland, licking over it before hovering over the Omega. "Mhmm...." Deku whimpers gently, satiated beyond belief - if the sensations bleeding through the one-way bond he's created with Deku say anything. "Good, now bite me," Katsuki huffs out, the fog of rut that he had fallen into clearing away, cradling the back of Deku's head to pull the whining teen closer to his neck. Deku's hands hook around his neck and kiss at his neck and lick up the vein on the side of his neck. He can feel the gentle tease of those needle-sharp Omegan fangs grazing over his skin. Katsuki grunts when he feels Deku's jaw clamp down around his scent gland, and those little fangs pierce the naturally tough skin of both Alpha and dragon-kin skin.

"S-Shiit," Katsuki gruffs as he feels the bond snap in place, now flooding each other with the other's emotions, another fat rope of cum pumping Deku full and making the little thing preen.

Katsuki croons and kisses Deku gently, falling to the side and taking the purring Omega with him. "So pretty, and so utterly mine," An ebb of possessive nature - bleeding from both sides of the coin, Alphan, and dragon-kin - bleeds into his voice and makes Deku shiver as the little teen settles against his bicep, nodding gently. "Mhm," Deku confirms, arm looping over his side. "Yours, all yours,"

Katsuki settles with a deep croon echoing in his throat and a grin on his face.

Katsuki hisses as his cock comes free with a flood of cum following it, making both him and Deku grunt. The little Omega shivers in his arms and digs his face into Katsuki's sternum to huff and shiver there. He can feel Deku's arm cinch tight around his waist, digging into the small of Katsuki's back, moaning a pathetic little keen as the river of cum leaks from his cunt. "K-Kacchan..." Deku whispers, an ebb of neediness sparking something dark and deep inside of Katsuki, pupils shifting and vision hazed with a look of greed falling over his face. "Fuck me again?" Deku whispers, pulling him closer and looking up at him with those big eyes that could only spell nothing but trouble for Katsuki.

The blond grinned and groped Deku's ass, dipping between slick asscheeks to press at the cum-filled cunt, pulling the fat mound apart with a lazy grin. His tongue lolled out, now shifted into the one his dragon form had, watching Deku's eyes follow the wriggling muscle.

"My fucking pleasure," Katsuki crooned, pushing Deku on his back and devouring the Omega.
