You're The Exception to the Norm

Winner of the 5a Term Fic Poll! The winning theme was: ' Dragon King Bakugo doesn't know how human anatomy works. That doesn't stop him from trying to breed Deku'! 

Looking back, I think I should've included some belly bulging and more emphasis on their size differences so I may go back in and fix that at some point! 

 -

Humans didn’t normally interest him. In fact, it was more honest and truthful to say that he despised them. Considering how many of his kind they killed every year in order to harvest scales, blood, horns and organs, it was only by his own grace that he had obliterated all of them. If he had things his way, he would’ve done that a long time ago but even the King has to answer to someone. In his case, the High Priestess – a dragon of significant eras, who was the first to be able to transform into a form similar to that of humans. She wanted peace between them, rather than increased violence and it was her effort that resulted on the human Kingdoms making it illegal to poach dragons. Of course, some humans never learned when to stop and continued killing his kind anyway – those, though, the High Priestess gave him full reign to do whatever he pleased with. As she had told the human Kingdoms: both sides would do their best to maintain peace but if violence was directed at the Dragons, she would not hesitate to turn the other way as teeth gnashed and claws ripped through delicate, weak flesh. For the most part, that subtle threat worked – the number of human related dragon fatalities had increased significantly with the agreement reached between the two Kingdoms. Not how he would have done things but, as his Advisers and Generals were quick to point out, he should be happy regardless. 

Happy wasn’t how he thought he should be feeling. There was still a long way to go before he could accept humans as being anything other than walking, talking embodiments of destruction. Unfortunately, his refusal to put in just as much effort to get along with humans as the High Priestess and others had resulted in her taking some unnecessary measures. In her mind, there was no continuing peace with humans until he came to accept humans. Not even his annoyed insistence that the agreement only remained strong as long as he was a source of fear for the humans. If they removed that terror, there would be nothing stopping them from continuing to be a deadly pest for Dragons. He didn’t need to be on friendly terms with humans – he was meant to be their enemy, the enforcer, the protector. Not to mention, he didn’t want to be on good terms with them. Unlike the High Priestess, who heard of every cruelty inflicted on them second hand, he saw the extent of the damage. He had witnessed enough corpses being desiccated to never want to even grace a human with a kind word, let alone an offering of friendship. 

Of course, the broad who always thought she knew best wouldn’t have any of that. He knew she had been scheming to get him to abide to her orders to make nice with the humans but never would’ve thought she’d go to this extent. This was a level of ridiculousness that made him wonder, not for the first time, if she was right in the head. Leaning back in his chair, arms crossed over his chest, a deep frown marring his face, Katsuki blew out a harsh breath through his nose. For someone who so strongly emphasized that he needed to play nice with humans, she certainly wasn’t setting a good example right now. Lying on his bed, completely nude, hands bound in front of him, ankles tied together, staring back at him with wide, confused eyes, was Izuku, an apothecary who had been employed by the High Priestess, along with several others, to help make substitutes for the multiple vital potions that required Dragon ingredients. If someone were to ask what he thought of humans, he would tell them without hesitation that he hated them but if that question was followed up with ‘what about Izuku?’, he would have to make a difficult decision: lie and snarl that he hated all humans, including Izuku or firmly put an end to that conversation. Not that either method had a lot of staying power – hiding how much this stupidly adorable, earnest, kind and energetic human meant to them was practically impossible. 

He hated all humans…but Izuku was an exception to that. Born in the High North, Izuku had never even seen a dragon until a year ago, when he grabbed the attention of both Katsuki and the High Priestess by being part of an impromptu rescue and escort group that saved a number of baby Dragons from being killed. Katsuki eyes flickered down to Izuku’s chest, following the length of a long scar that ran from his right shoulder to his navel. When he first met Izuku, he was grimly patching himself up after not being able to dodge quickly enough and getting a sword to his torso. The wound wasn’t fatal but it had him out for the count for several days. Izuku, though, had been in good spirits, as he conveyed to Katsuki with a pained grin on his pale, sweaty face. The blade had been meant for one of the babies – he was happy that he could use himself as a shield to save her. At the time, Katsuki had thought Izuku was just trying to get into his good graces but when Izuku had frantically apologized to him for speaking with him so nonchalantly after learning he was King, he realized that his concern, his willingness to sacrifice himself for a Dragon was genuine. 

By the time the escort mission back to the Dragon Kingdom was underway, Izuku was back on his feet, fully healed and ready to help out however he good. Several heads had whipped around and many pairs of eyes bulged when Katsuki quietly allowed Izuku to accompany them. None of the other human participants of the rescue mission were permitted to come along, which caused quite a stir amongst his fellows when they learned that he’d given Izuku permission. Then, he hadn’t know why he had agreed but when Izuku looked up at him with those big green eyes, when he passionately exclaimed all the ways he could help…he just couldn’t tell him no. 

That should’ve been his first indication that Izuku was going to be different from all the others but, at the time, he had ignored it. The fact that a human was able to get to him like that had been more a source of annoyance than anything else. This annoyance was further exacerbated by the fact that he often found his eyes drifting over to Izuku. If he didn’t know where he was, his gaze unconsciously searched for him. There’d been a few times where, after not being able to locate him, he became antsy and could only calm down when he located Izuku. He chalked it up as him not trusting the human and wanting to know where he was so he could know what he was doing but, as one of his Generals had playfully pointed out, it was less than and more…he just wanted Izuku close by. Not because he thought he’d do something bad. He just wanted him…there, close to him, within eyesight. It had been frustrating at the time but now, a year later, he could recognize it for what it was. 

When had it been that he started to realize that Izuku was different? No, that wasn’t the right question. He had always known that Izuku was different. He wouldn’t have let him come along with them if he hadn’t thought there was something unique about him. No, the question to be asking himself was when did he realize that Izuku was someone special to him? Katsuki sighed, slumping back in his chair. An easy question to answer – when he thought that Izuku was going to be married off to some Noble woman. It had all been a misunderstanding, born from one of his General’s son’s friend’s mishearing something and that information becoming even further garbled as it traveled up the vine to him but he could still remember the cold grip of terror that had seized him when he thought someone was going to take Izuku away from him. Unfortunately for him, word of how badly he reacted got up to the High Priestess. He had thought she wouldn’t stick her nose this far into his business but this was obviously proof that he should have thought otherwise. 

Katsuki’s brows knit together over a lightly furious gaze. Was that why she had gone to this absurd length? He wouldn’t put it past her but really, drugging and tying up Izuku then dumping him onto Katsuki’s bed, next to a letter that practically commanded him to take Izuku as his mate was extreme, even for that deranged broad. Sighing heavily, Katsuki scrubbed a hand over his face. That witch was really starting to push him. This was an obvious attempt on her part to weaken his hatred for humans. Surely, if he took a human as his mate, he was more likely to go easy on them, right? If it were any other human, that’d be a big, fat ‘NOPE’ but this was Izuku…he had already managed to quell his hatred towards humans just by being here. If he took him as mate…there was no doubt in his mind that this position of being the big, scary Dragon that punished any human who was dumb enough to hurt one of his own was going to change. For that reason alone, he knew he should untie Izuku, walk straight up to the Head Priestess and tear the letter to shreds in front of her. But, knowing and doing were two completely different things. He’d been sitting there for close to 20 minutes now, staring at Izuku, who had only recently awoken from whatever spell or drug she used on him – no closer to doing what he knew he should than he had been when he first read that damned letter. 

Thing about the Head Priestess…she knew him too damn well. He couldn’t hide anything from her. That fucking broad knew how hard it would be for him to resist this. Making Izuku his…covering his small, pale body with his bite marks so that everyone would know just who he belonged to; pinning him under him, stuffing him full, filling him up until his smell changed, becoming even sweeter, stronger but, even more importantly, intermingled with his scent, creating a brand new smell that was entirely representative of their bond. The mere thought sent a sizzle of heat radiating down to his crotch. His cock twitched inside the constraints of his trousers. Izuku’s scent changing…his belly swelling with the new life growing inside him, created from their bond…Izuku being his, only his…Katsuki sighed heavily, dropping his head. Fuck, that dumb broad knew exactly what she was doing. As much as he despised the idea of doing anything that she wanted, simple fact of the matter was…he wanted Izuku. He had wanted him ever since he had first laid eyes on him. He wanted to possess him, to cherish him, to make him happy and keep him safe. He wanted to make Izuku his mate! 

“Ka…Katsuki?” Izuku soft, hesitant voice spoke up, pulling him out of his thoughts, “Wha…What’s going on? Why am I tied up? And…and naked?”

…curse the Gods, he was going to do something that wretched woman wanted him to. She was never going to stop holding this over him but…Katsuki raised his head to settle his gaze on the still very confused Izuku. Let her gloat; let her make that obnoxious smarmy expression she always did when he had to admit she was right – if he got Izuku out of this deal, he’d gladly take that annoyance. However, he wasn’t going to let go of his hatred of humans that easily. Couldn’t give her everything, after all. Her head was big enough already. Getting to his feet, Katsuki walked over to the bed. Judging by how he had been brought here, he had reason enough to believe that Izuku wasn’t aware of the arrangement between them. Not surprising – the High Priestess wasn’t one to think of the finer details. Though, annoyingly, she had obviously figured where this would go. The letter had indicated that Izuku had been ‘prepared’ before being brought here…whatever that meant. He was assuming it meant he’d been given a portion to make him especially fertile. Again, a little annoying that she had butt her way into his business. Was she implying that his seed wasn’t strong enough to get his mate pregnant the first time around? 

“Katsuki?” Izuku spoke up again, peering up at Katsuki with big, bright eyes, “What’s-?”

Ah, forget it. He didn’t care about her reasoning. He just wanted to make Izuku his already! Hopping up onto the bed, he crawled on top of Izuku, who shrunk back against the mattress. Eyes widening even further, a jolt visibly wracking his significantly smaller body, Izuku squawked out something that he couldn’t understand but sounded vaguely like ‘what’re-!’. Cute…curse the fucking Gods, he was so godsdamned cute! And his…Izuku was all his…Izuku was his mate! His! His! 

“Izuku…” Katsuki breathed, cupping the side of Izuku’s face, marveling at how smooth and soft his skin was against his rough, calloused palm. He dipped down, bringing their faces close together. 

Izuku shrunk back even further, a bright splash of red dyeing his freckled cheeks. He had just enough time to choke out, ‘Kat-!’ before he closed the distance between them, pressing their lips together in what started as a soft, chaste kiss but as soon as he felt Izuku’s lips on his, that wonderful soft warmness, his control snapped. Exhaling sharply, he hungrily devoured Izuku’s mouth, shoving his tongue inside to swipe it over the roof, the sides and teeth to taste every inch. Sweet…so godsdamn sweet! Katsuki was instantly hooked. He couldn’t get enough of this incredible flavor. Izuku was still and slack underneath him, the only movement of his body being an uncontrollable tremble but as he continued to savor the taste of his mouth, the sensation of their lips gliding together, he started to hesitantly push up into him, returning the kiss with an adorable clumsiness. Katsuki moaned low in his throat. His large hand slipped down to curl around the back of his neck, pulling him even closer. Thick heat rolled through him, heading straight down to his crotch. He chuckled in playful exasperation. Just a kiss and he was already this turned on, huh? His cock strained up against the front of his trousers. He could feel a wet spot growing where the tip met fabric. This was the kind of power Izuku had over him, huh? Couldn’t say he was surprised. 

Breaking the kiss with a sharp gasp, Katsuki slipped further down, trailing a line of wet kisses along the curve of Izuku’s jaw then followed the curve of his throat. He took his time, sucking, licking and biting everywhere he could reach, leaving bright red marks all over Izuku’s skin. Sweet…every inch of him was so sweet…he couldn’t get enough! He smelled so good, tasted so good! He smoothed his hands over Izuku’s shoulders, his chest and stomach, dragging his blunt nails to leave faint red trails. One of his hands brushed over Izuku’s nipples. When that earned himself a gorgeous gasping moan, his hand zipped back up to fondle and squeeze Izuku’s pec, crushing his nipple underneath his palm. Izuku whimpered loudly, thrusting his chest up into Katsuki’s hand. The gorgeous color dyeing his freckled face had deepened even further. Fat droplets of sweat dotted along his brow. Beautiful…gods, fuck! He…he was so beautiful! He couldn’t resist him! He’s never been able to resist him! From the moment he first laid eyes on this adorable, amazing human, he was addicted to him! 

“Ka…Katsuki-!” Izuku gasped wetly, tilting his head back to give him better access. 

A bolt of electric pleasure pierced through his body. What last little scraps of control he had left vanished underneath the immense wash of heat that rolled through him. His name…fuck, fuck, fuck, he wanted to hear Izuku say his name like that even more! Growling low in his throat, his lips stretched into a feral grin, Katsuki wrenched up, reaching behind him to grab hold of Izuku’s bound ankles. Slipping a dagger out of a hidden pouch in his boots, Katsuki deftly cut the ropes binding both his ankles and wrists, taking extra care to not accidently nick Izuku. Bright green eyes stared up at him, confused and hesitant. Tossing his knife onto the floor so he wouldn’t have to fiddle around with getting it back into its holder, Katsuki shoved his larger body between Izuku’s trembling legs. A loud, panicked squeak came rippling out of Izuku’s throat. His eyes widened even further as the color in his face darkened.

Katsuki’s clothed erection bumped against something equally as hard. Izuku yelped again, his legs twitching against Katsuki’s sides. Panting heavily, Katsuki glanced down, his grin growing even bigger when his gaze landed on the small, plump cock standing straight up from a nest of dark pubic hair. So, human anatomy wasn’t that much different, huh? Though, Izuku was so small. Was that normal or was it just another adorable trait that this stupidly cute human possessed? Ah, who cared? All he should be focusing on right now was Izuku. Katsuki wrapped his fingers around the sopping wet length, a spasm of dizzying heat erupting in the center of his head when it twitched against his calloused palm. This…this right here was proof enough that Izuku was enjoying himself too, right? Giggling under his breath, Katsuki leaned down to drag his tongue along the slit, gathering up a mouthful of the sweet, thick fluid pouring out of him. A shudder rushed through his body. Good…good, good, he tasted so fucking good! 

“Wai-! Wait-! Katsuki, what-?! What is going on here?!” Izuku cried out in alarm, “Whoa, whoa, wait! Wait! Kats-!”

Stretching his mouth open, Katsuki took the small head into his mouth, clamping his lips around the quivering shaft. The loud, wailing cry that Izuku let out was as gorgeous and sweet as a betrothal bell ringing. Curling his large hands around Izuku’s thin waist to keep him from moving around too much, Katsuki pushed all the way down, taking in all of Izuku’s cock. He rubbed his tongue against the underside, seeking out all the little spots and places that would make his Izuku whimper and whine. Loud, wet moans, intermixed with infrequent exclamations of his name and general confusion, rained down onto his head. Izuku squirmed underneath him, his hips bucking as much as they could with him holding him. More of that sweet fluid poured out of his cock. Katsuki greedily swallowed down every drop, sucking hard on the length to milk out even more. Saliva dribbled down Izuku’s plump cock, soaking his pubic hair. Tilting his head back slightly, Katsuki let his gaze roam up the smooth expanse of Izuku’s stomach and chest before resting on his face. Their eyes met. Izuku jolted underneath him then quickly looked away, an embarrassed expression dominating his features. A flash of annoyance echoed in his belly. 

This bastard…how dare he look away from him? Slipping off his twitching cock with a loud squelch, Katsuki reached up to grab hold of Izuku’s jaw, yanking his head back into place so that those beautiful, bright green eyes were only looking up at him. Izuku weakly tried to wriggle away but Katsuki tightened his hold…mostly to show Izuku that he had best behave but also to watch his round, freckled cheeks squish around his fingers. Staring down at him, he momentarily forgot the reason why he had grabbed him in the first place, too overwhelmed by how adorable he was to be annoyed anymore. Those cheeks…his face, fuck, he was too adorable! Katsuki leaned in, bringing his face close to Izuku’s. At first, he thought he was going to kiss him again but those adorable chubby cheeks were drawing him in. He opened his mouth and gently chomped down on the squish, moaning happily as his teeth met the plump curve. Izuku squeaked but it didn’t sound like a pained one so Katsuki continued gleefully gnawing on him. His…his, his, Izuku was all his…from these adorable cheeks to that perfect penis, all the way down to the delicate tips of his toes and fingers and back up to the very last floof of hair…his, his…his, his, his! 

“Ka…Katsuki?” Izuku said hesitantly, “What…what are you-?”

“You keep asking that.” Katsuki replied, trying to sound annoyed but badly failing. Straightening up, he flashed a lopsided smirk, “Isn’t it obvious?”

“No! I mean, I can guess but I don’t understand. Why are we-?”

Sighing irritably, Katsuki returned his attention back to Izuku’s lower half. This was where he was running into a bit of an issue. Truth be told, he wasn’t really sure where to go from here. Human anatomy was proving not to be that different from Dragons but he still wasn’t certain on how to get Izuku pregnant. Male, female and genderless Dragons could all get pregnant without issue – a boon gifted to their race to ensure that even if their numbers dwindled, they always had the capability to reproduce – but humans were a different story. Katsuki had to chuckle – for once, he was annoyed by not having enough information on humans, of all things. Well, best thing to do when he didn’t know something was to ask, right? 

“Oi.” Katsuki said, looking up at Izuku, “How do humans reproduce?”

Izuku gawked up at him for a moment then yelped, “WHA-WHA-WHAT ARE YOU ASKING?!”

“Loud.” Katsuki grumbled, frowning at his mate, “It’s a simple question. What’re you getting to embarrassed about?”

“Why are you asking me something like that?!” 

Katsuki blinked then gestured vaguely at the position they were in, “You can’t figure that out?”

“That-!” Izuku exclaimed. Exhaling shakily, his brows knit together over a confused stare that was really starting to get on Katsuki’s nerves, he said, “I…I don’t understand any of this, Katsuki! Why…why are we doing something like this? Why am I tied up? What are-“

“Are you trying to piss me off?” Katsuki interrupted him, the corner of his eyebrow violently twitching, “It sounds like you’re trying to make me mad.”

“No, no!” Izuku squeaked, furiously shaking his head, “I just don’t understand! Why are you-?!”

“It’s fucking obvious!” Katsuki roared, grabbing hold of Izuku’s legs. He yanked them open wide, pushing them up so his knees were at his shoulders. Izuku let out another startled wail, his eyes bulging. Clenching his teeth together, his lips stretching into an infuriated grin, Katsuki snapped, “But if it’s that hard for you to understand, then I’ll show you!”

“No, wait, wait! Katsuki!”

If this bastard didn’t want to tell him, then he would just figure it out himself! That broad said in her letter that he was already prepared and ready for him so that must mean that the normal method of getting male Dragons pregnant still applied here! Curling his fingers around the base of his shaft, he pushed in close, leading his cock down until the tip pressed against something that was definitely a hole, right where he thought it would be. Judging from the way Izuku flushed even darker and squeaked, his eyes stretching even further open, his cute cock twitching enticingly and the fact that he was incredibly wet and soft, Katsuki felt pretty confident in guessing that he was on the right track. A wild trill of excitement slowly radiated down from between his shoulders, trickling down in a wave of warmth that became near unbearably hot by the time it reached his crotch. Sweat popped up in fat droplets on his forehead. Desire pulsed wildly inside his mind, reverberating with the desperate need to bite, to impregnate, to claim. His heavy lidded gaze slid up the length of Izuku’s trembling body, stopping when their eyes met. 

“Ka…Katsuki, just wai-! MNNGH!!” 

He couldn’t wait any longer. Izuku…Izuku was his! His! Lunging down, Katsuki smashed his lips against Izuku’s in a sloppy, rough kiss. Izuku trembled powerfully underneath him. A lazy spark of heat burst in his belly at the sensation of Izuku’s plump cock, trapped between their bodies, twitching against him. Having found his entrance and lined his cock up perfectly, he moved his hand back to underneath Izuku’s knee, holding his legs open wide. Pulling away from the kiss with a harsh exhale, his lips coated with the sweet taste of Izuku’s mouth, Katsuki focused on his adorable flushed face as he pushed his hips forward. The head of his cock slipped through a tight ring of muscle to sink into a tight clench of hot wetness. Izuku’s eyes widened then squeezed closed. He let a loud throaty wail that nearly sent Katsuki into an episode of wild, fervent bucking. Grinding his teeth together, struggling to ignore the shrieking bolts of pleasure racing through him, Katsuki kept pushing in until his pubic bone was pressed snugly against Izuku. He had to pause for a few moments, panting heavily, blood roaring in his ears, his body dominated with a kind of beating, snarling pleasure that he’d never experienced before. Izuku wasn’t his first – while he’d never tried mating with anyone before, he’d gone to bed with a sparse few who were lucky enough to get his attention. None of them, even the ones who’d made him feel like he’d just eaten the fruits of the goods, had made him feel like this. 

This…this was what it felt like to be intimately connected with his mate, this was what it was like to claim the one meant for him. A swell of warmth and glee bloomed inside the center of his chest. Grinning widely, his breath coming in fast, hard pants, Katsuki straightened up so that Izuku would have a good look at him. The confusion was still there but it was diminished, overwhelmed by the lust lacing his expression. Bright green eyes, swimming with a checked desire, flickered up to meet his gaze then quickly danced away. The color in Izuku’s cheeks darkened even further, practically hiding his abundance of freckles in the wash of red. Fuck…who gave this fucking asshole the right to be this stupidly cute?! Dragging his tongue over his bottom lip, Katsuki began to shallowly pump his hips, keeping the majority of his length buried deep inside Izuku’s hole. Izuku cried out wetly, his mouth hanging open as he panted raggedly. The smooth, soft walls clamped down around him, squeezing him, stroking him, sucking him in even deeper. Every inch of his body was drenched in an electric heat. Sweat accumulated underneath his arms and soaked his chest and back. Katsuki laughed low in his throat. They had only just started but it already felt like he was going to cum. His balls hung heavy and hot between his legs. His cock felt like it was melting. 

The power his mate had over him already…this bastard was dangerous…A tremble wracked Katsuki’s body. The warmth beating away wildly inside his chest grew even more intense. His heart fluttered with excitement. Giggling drunkenly, he leaned down again to capture Izuku’s lips in another kiss – this one deeper, stronger, meant to drench every inch of his mouth with his taste. Izuku whimpered but, after a moment of hesitation, he pushed up into him, clumsily returning the kiss. Katsuki’s eyes widened. His breath caught. The blaze of fire burning in the base of his belly erupted in a volcano of screeching desire. Growling with a fury born from how disgustingly cute this monster was, Katsuki dropped down on top of him, wrapping his arms tighter around his significantly smaller frame and rapidly ramped up the speed of his thrusts, slamming into Izuku with enough force to send him jolting upwards with every hard collision of their bodies. His knot smooshed against Izuku’s hole every time they came close together but didn’t slip inside. Izuku squealed and wailed underneath him, clinging to him, his blunt nails dragging across his sweaty skin. His trembling legs curled loosely around his hips. His hole clamped down even tighter around him, squeezing him with a strength that was nearly painful. 

With Izuku finally reciprocating, the slight hold he had left on his self-control snapped. The incredible pleasure was too intense, too overwhelming for him to fight against. It roared through his veins, dominating every nerve ending until there was no heat, no wetness from his sweat, no brush of his clothes against his skin – all he could feel was Izuku’s hot skin pressed against his own and that erratic, all-encompassing pleasure. In that kind of state, all he could do was cum, filling his mate up with his seed. Jerking away from the kiss, pressing his forehead to Izuku’s, he grunted out, “Get pregnant, get pregnant!” 

“Katsuki-!” Izuku wailed. His trembling hips strained up off the bed, grinding against him. As Katsuki was slamming in one last time, he came with a loud cry. Thick ropes of cum splattered across his and Katsuki’s stomach. The pressure inside him became even more intense, pressing down on him so hard, it was difficult to pull out again. 

Choking out a gasping croak of Izuku’s name, Katsuki lunged down to sink his teeth into the smooth flesh of his shoulder. Izuku’s soft skin burst underneath the sharp points of his teeth. Blood seeped into his mouth. Even his blood was sweet…an incredible wash of desire to devour every inch of him grabbed hold of him with enough strength that he couldn’t resist sliding a little further up and biting Izuku again. Growling low in his throat, his hands curling into tight fists underneath Izuku’s back, Katsuki reared his hips back then slammed forward. His knot pressed insistently to Izuku’s hole then, with a loud squelch, pushed inside. His cock swelled up even bigger, twitched inside the tight constraints of Izuku’s hole. An immense rush of ecstasy tore through him, leaving him shuddering and gasping on top of Izuku as he pumped his insides full of his seed. Izuku’s eyes bulged. He threw his head back, mouth hanging open as a loud, squealing wail came rippling out of his throat. His blunt nails dragged along Katsuki’s back, leaving bright red trails across his skin. 

“Too much-!” He cried, “Too much-! Too full-! Can’t-! Can’t-!”

Pushing out a moan through clenched teeth, Izuku came again, adding even more wet mess between them. He collapsed back down onto the bed, panting heavily. Smiling lazily, his face burning with a scorched heat, Katsuki nuzzled the side of Izuku’s throat, dragging his tongue over the bite marks. His…his, his, Izuku was now fully and completely his…

Only…Katsuki’s brows knit together. Izuku’s scent hadn’t changed. It was the same as it was before – he couldn’t pick up on a hint of difference. Straightening up slightly, he looked down into Izuku’s dazed, flushed face. Brushing his fingers through Izuku’s sweat drenched hair, Katsuki waited a few moments to see if it was just taking a little while for his scent to change. No luck – even a full minute later, there was no discernable change. Frowning, Katsuki leaned further back. That wasn’t right. Hadn’t he been warned several times during his youth that he always needed to be careful whenever he decided to be intimate with someone because his seed was so strong and could very easily get someone pregnant? Why was it taking so long now? Katsuki cocked his head. Ah…that warning had only been in relation to other Dragons. He could remember hearing that it was difficult for Dragons to get human women pregnant so it might be especially troublesome to impregnate the males, even for someone like him. The corner of Katsuki’s lips curled into a teasing smirk. 

Fine with him – that just meant both he and Izuku were going to need to keep working hard to make sure he got pregnant, even if that meant doing it for the rest of the night. He wouldn’t stop until Izuku’s scent became even sweeter and he could feel the thrum of new life growing in his belly.
