How To Train Your (Horny) Dragon [Dragon!Kiri x Baku x Deku]

[NicTheDjinn]

Poor dragon, so desperately eager... He was honestly glad to feel better about the whole thing, not just for his own sake, but for Eijirou's as well. He'd feel terribly guilty to have baited him like this only to leave poor Ka-chan to have to deal with him. Speaking of Ka-chan... "A... Sea---eehhhh?! Ka-chan!" You could see the moment his mind put it together, the poor guy flushing a cherry red and tucking up into Kirishima's neck to hide out of embarrassment. He bit his lip as the blond continued, whimpering softly in want. In spite of his embarrassment, that sounded wonderful and he knew it would help. He was a virgin and Eijirou was far from small.

A gasp left him as that wicked mouth found its way to his earlobe to give it a quick little nip. He really was making a very good argument... He hesitated in giving his answer, listening to Katsuki turn his attention to his lover for the moment. He shivered, able to feel something slowly creeping down his inner thigh, the realization it was his own slick reddening his cheeks further. "I... I-I want to do that f-first one you said..." He squeaked in a tiny voice, surprised that he managed to get out the words to start with. "C-could you lay down for me, K-Kirishi-shima...?" Oh no, the nerves were eating him up alive, but he was determined to see it through at this point. He had to, he couldn't back out a second time!

He pressed a final kiss to the side of Eijirou's neck before anxiously taking a step back so the dragon could move more easily as he wished. This left him unintentionally on his own, even the small amount of distance feeling like too much at this point. He had the urge to hold someone's hand or hug or anything really, so long as it was grounding... He'd be alright. He just needed to wait a moment. He'd be fine. Then he'd... Oh gods. He was really going to do that! Poor thing was working himself up, his blush creeping down his neck to his shoulders and even the tops of his small chest.

He was greatly enjoying having both of them so close, being able to hear the soft wet noises of the attention Katsuki gave to their inexperienced lover. That was going to change, very quickly. Not quickly enough for his raging hormones, but he could battle with that side so long as Izuku was anything but enthusiastically on board. The way he hid against him pulling a low keen from the dragon, trying to soothe at his shyness. He didn't need to be shy, and Eijirou personally took it as a mission to make sure he was as comfortable as possible with this. Even if he was struggling to think straight.

The words to answer Izuku died in his throat when Katsuki's hand stroked along his tail and inwards, lighting a fire along his skin in the best way. He had to quite literally bite his tongue to keep down the pleasured snarl when that hand found where he needed it most, touched him and blanked his mind for a solid minute because finally the relief seemed to kick in. He could not, however, hold back the way his hips moved into the stimulation, chasing his hand as it stroked over his length and made him dribble down onto the blond's fingers, wet and messy and the sound it made riled him up further which just made more of a mess. At this rate he would match Izuku, slicked with his own precum.

He felt Izuku move away, felt the mournful noise rumble in his own chest, but let him go. Watched him with eyes that looked more black than red with how wide his pupils were with the sheer want. It was with a great deal of remorse to pull away from his mate and the nice warm hand on his cock to listen to his new mate, but he did so panting and moved to lay back on the spread of bedding for him. Mindful of how he placed himself so it was comfortable, it put himself on display as well, and then holding his hands out to Izuku with a little curling of his fingers, c'mere. He could feel his mouth pooling with saliva at the thought of getting to taste him where he wanted to most, wanting to lick him open and pry at his insides with careful fingers until the muscles gave in to him and let him in deep.

Oh, he was going to mate him so good. Show him how much he already cherished him, how well he could please him like this. He wanted to feel him shake apart above him.

As cruel as it sounded, Katsuki honestly took great pleasure in riling both of his partners up like this, helping them both psych up for what was to come. And, though Eijiro knew it, Izuku will find out soon enough that Katsuki enjoyed bringing as much pleasure as possible to his lovers, making sure they're wholly satisfied. When the dragon bit back a pleasured snarl at his attentions, Katsuki chuckled lowly, enjoying how much the redhead was leaking already. "So, so eager, big boy.... Don't forget, you have to play nice for Izuku.... He's new, fragile, so you can't go too fast, alright?" Katsuki gently warned as Izuku pulled away, allowing Eijiro to lay back, present himself comfortably for them both. The beast was quite the sight to behold-- to Katsuki, Eijiro was the image of perfection, perfectly built yet still inviting in appearance, a sweet face that could also strike fear or intense lust easily, and a heart of gold that was strong enough to beat down the more feral instincts he held inside for the sake of those he cared for. The fact Katsuki was able to share such a treasure said a great deal, though, Izuku was a treasure himself, even if the blonde took far longer to realize it. It almost made the blonde feel a tad greedy, finally getting the chance to have both, while also sharing his dragon with Izuku.

Katsuki took Izuku's hand gently, noting the greenette's nervousness. "It's going to be okay, he's very good with his tongue and fingers-- believe me." He smirked softly, before pressing a gentle kiss to the other's cheek, and once he was ready, carefully helping Izuku to kneel over the dragon's face. "And I can assure you he's strong enough to hold you up if the pleasure makes you feel weak-- bastard loves milking me before giving me what I want when he isn't rutting." The blonde snickered softly, his own lustful eyes looking over Izuku's frame, how it was soon poised perfectly over Eijiro's ravenous lips.

Once that was settled, Katsuki moved himself to partially lay between his lover's legs, positioning himself comfortably, using one of his dragon's thighs like a most comfortable pillow. The amount of times he's joked about having his skull crushed like a melon never ceases to amuse Eijiro. But, humor aside, Katsuki had a task to handle, and it was more than a hand full. With a practiced tongue, the blonde licked a long, broad stripe along Eijiro's shaft, catching as much of his arousal-slick as possible, before swiping along his slit with a husky chuckle. "Such a needy dragon.... Absolutely spoiled, too~♡ Having two eager mates to satisfy you...." He purred, before pressing an almost sweet kiss to the other's tip, then taking him into his mouth with a pleased sigh, all while his hand stroked what wouldn't fit in his mouth. It was hard to believe, but Eijiro was just slightly too thick for his jaw to handle beyond a mouthful, but Katsuki managed well, between his handiwork and skill with his tongue. He held a slow, steady pace, his eyes slipping closed as he worked, focusing on the sounds his lovers would make. Sure, his own arousal was aching, as well as elsewhere, but he could wait far longer than Eijiro could. Besides, Izuku will need a resting turn, and Katsuki could easily take over for him until the greenette was ready once more. He doubted Izuku could handle more than one round in a row, especially when stuffed full of potent seed. Eventually, if they all are in agreement to be a polycule, Izuku will have a greater endurance, be able to handle more of Eijiro's vigor and virility. For now, though, Katsuki wanted to make sure the poor boy wouldn't be broken in half, or otherwise hurt because he was too eager.

It was so hard to ignore how good the dragon looked, just barely restraining himself like this. It certainly made him feel wanted, not to mention the added attention he never thought he would get from his childhood friend. It still blew his mind that they had finally grown past it, all thanks to Eijirou's encouragement. He honestly hoped that they would move forward together after this and that Eijirou wouldn't decide that he was uncomfortable with him joining their relationship properly when he was no longer in rut.

He watched on as Eijirou laid himself back for him and didn't miss how he was not so subtly putting himself on display. It made sense. He was in rut and the entire point of ruts and heats was mating and mating generally came after courting in an attempt to impress your potential mate. Well, he was certainly very impressed! With that said, embarrassment was still a thing and knowing exactly where the dragon's mouth would be flustered him enough to hesitate.

This in of itself didn't last long as Bakugou was there to encourage him and keep him moving forward. He could feel the heat not just in his cheeks, but his entire face as he was guided over and helped down to his knees. He shifted about for just a moment to make sure he would be comfortable before shyly lowering himself down further. A shiver skittered down his spine and a whimper tumbled from his lips as he felt the first heated puff where he'd never allowed anyone else before. Despite his misgivings about his own body, the reassurance along with the brunt of the lust being directed at him was enough to keep him from crumbling into self doubt again.

Still a little shy about actually lowering himself all the way down, he hesitated just short of making contact with the other's waiting lips. He wasn't really considering the fact that he was well within range of a human tongue, let alone the long forked thing the dragon possessed. On top of that, there was nothing stopping Kirishima from simply leaning up or pulling him down to rest properly. What's more, the doofus got distracted by the blond's praise behind him, looking over his shoulder gist in time to watch his lifelong crush drag the flat of his tongue up the redhead's length. His breath caught then hitched, lust throbbing deep in him, unintentionally dripping slick down onto the dragon's lips.

[cryptidchalupa]

Katsuki's words echoed loud in his mind as he was getting settled, as Izuku came over and close. Reflexively he reached up to help guide him as well, the proverbial command to behave acting like weighted phantom shackles around his limbs so he didn't outright just yank him down and dive right in. Play nice. He refused to scare him away, especially now that they were already this far. The soft heat of his bare skin settling around his head and shoulders, he couldn't help but to skim his hands reverently up the backs of his legs, along the swell of his ass and up his back before back down again. It was as soothing, he hoped, as it was a way to convey more of his desire. He wanted to touch him, feel him, in any way that he could and he just didn't possess the words for it.

The dragon has nuzzled his way against his new mate's thigh, sharp teeth gentle against the skin as he bit him but not hard enough to leave any lasting mark. Just a faint line of pink where his teeth pricked at the surface while his hands made close friends with the meat of his ass, kneading at the muscles and thoroughly enjoying creeping his way closer and closer even after the boy literally dripped onto his mouth. And the amount of self control he had left keeping him from licking it from his lips just yet, wanting it straight from the source first.

He teased at the crease of his hip and thigh with a playful flick of his tongue, rumbling a low purr like noise in appreciation. Just the taste of his skin had him more excited. He was just about to slowly drag himself to Izuku's core when Katsuki deemed it fit to actually touch him again. His moan was muffled against Izuku's thigh, turning into a low growl as heat took over the head of his aching cock. He tried not to dig his nails into his inexperienced partner, but the pleasure zinging through him got the better of him and he may have squeezed his handfuls a little harder than he meant to before trying to gently rub at him in apology. Doubling up his efforts as he reached the apex between his thighs, panting hot against him as his higher brain functions were going out the window one by one, and all at once he couldn't wait anymore. No more teasing, he pressed up as well as gently tugging the other boy down to meet his tongue. Dragging it in a slow, savoring lick from the bottom of his sex to the top, lips closing around the swollen nub in a mock kiss before he let him go and returned to his folds to lick him clean on the outside of all the slick coating him here. This time his moan wasn't muffled, released loud and wanting against wet sensitive skin.

And Gods did it taste better than he expected (his tail may have thrashed a bit as the flavor washed over him, he certainly felt it thump against something). He smelled so good, and part of that was his rut and he knew that but... nothing about his rut would make Izuku taste like some delicacy. His grip going tight on him again, a little less apologetic about it this time around, holding him as he worked over him, gentle suckling to the soaked lips until returning to the top again and laving his clit with a generous amount of attention. It was all he could do against the heavenly torture of finally getting the stimulation he needed, and he definitely wasn't forgetting about the blond by a long shot. Once he got his rhythm going, one hand abandoned Izuku to reach down and card through fluffy light hair, curling around it when he paid attention to a particularly nice sensitive spot on the underside of his lower head. He wanted to thrust up into his mouth, but Katsuki was laying just right that he couldn't get the leverage if he tried, bastard.

[LovelyBones]

Seeing Izuku feel comfortable with their help made Katsuki happy, and he eagerly watched as his dragon began to devour the little greenette, feeling a small bit of jealousy, but for either position. With how that tail thrashed near his legs, and how the dragon moaned openly into the human, he could only assume the freckled adventurer tasted amazing. However, with that being the case, he wished he could be devoured with such vigor, too. Maybe he'll get a turn tonight, or another when the rut was over. Regardless, Katsuki was needy in his own right, and he'll make sure he gets his turn soon.

For the meantime, he reveled at how he was thwarting Eijiro's ability to thrust into his mouth, but he adored how his claws felt against his scalp, letting him know he was doing well. The blonde moaned as he suckled and stroked the large member his lover bore, and swallowed whatever pre came. When the curled fingers came, he licked languidly over that sensitive spot with a heated chuckle, red eyes looking at his lover's face, buried deep inside of Izuku's sex. "So, so hungry, my sweet boy.... do you want me to make you cum once before you show Izuku why I'm addicted~?" Katsuki all but purred, kissing at the other's cock lovingly, reverently before licking at that spot again. "Grip my hair twice if you want a little relief, big boy.... You know I love your hot seed~♡"

Really, he was eager to see if a climax would help tame Eijiro down or not for Izuku's sake, make sure he wasn't taken too roughly for his first time. Though, with how the dragon kept splitting the greenette open with that too thick and skillful to guess of his. He had a good feeling his childhood friend would be alright. Well, maybe unable to walk for a day or two after tonight, but between himself and the dragon, Izuku won't have to worry about needing to walk much anyways. Though.... he wondered if Izuku's stomach would bulge sweetly, once filled with his dragon's hot, thick seed, if the poor thing would be a happy, but sorta helpless puddle afterwards. Katsuki would just have to wait and see, and hope nothing goes awry.

[NicTheDjinn]

So many hands then he was settled, heart racing, and there was just so much to take in! Nothing was even happening yet, not really... He had hesitated and frozen in place in his embarrassment only to get distracted with watching his childhood friend do something so deliciously lewd. He couldn't help wondering what it would taste like... Would Katsuki taste different? Surely he would, they weren't even the same species. Even at the high speed his mind often traveled, he didn't have time to think much more on the subject before the hands at his thighs reminded him where his attention should be. Snapping his head back down, he fixated on the dragon below him again, cheeks warming up further.

Those strong hands rub along of his thighs then up to the softness of his backside, one of the few places he still had some fat to pad him out considering the training he subjected himself to. His touch traveled higher up only to come right back down and he couldn't help feel adored, wanted... He was sure no one had ever looked at him like this, at the very least he never noticed it. One thing he was sure of, no one had ever touched him like this and he found he never wanted it to stop. A small smile pulled at his lips shyly when his inner thigh was nuzzled, shivering when sharp teeth graze his skin. He knew very well the kind of damage those teeth could cause, should the dragon wish to cause it, but for that very reason was completely unafraid even though he was very much aware of the large artery that ran along the inner thigh. Eijirou would never purposely hurt him, let alone so gravely.

Along with the nip, those hands found their way back to his bottom, drawing a thoughtless whimper out of him as strong digits squeezed and kneaded there. His mouth was so very close now, each exhale puffing warm against his slick lips. A gasp was wrenched out of him as that tongue teased him, dragging along the inner crease of his thigh. So close... So very close...

Then the redhead was distracted, stifling his moan against his thigh. Oh right! Ka-chan! Looking back over his shoulder again he bit his lip lightly. Bakugou wasn't just licking at his length anymore... A gasp forced its way out of him as those strong digits gripped him harder, another whimper leaving him at the prick of claws. If it weren't for the fact he arched his back to press further into those now rubbing hands, he might have sounded hurt, but thankfully that was far from the case. So he was a masochist... How cute. And fortunate, honestly, or biting and scratching may have been a problem in the near future.

His attention was once again ripped away from the blond when he was tugged downward, looking down just in time to watch as that tongue finally took its first slow swipe along his slick folds. One of his hands shot up to cover his mouth to stifle the moan that left him. His eyes were wide with shock, not having expected it to feel like that, another sharp noise muffled as lips gave the briefest of sucks at his clit. He curled in then, landing on one hand while the other left his mouth to instead delve into brilliant red locks. His knees shifted outward, lowering himself in part so Eijirou wouldn't strain his neck, but also to chase the attention of that wonderful tongue.

"Y-you sound so good, Eijirou, a-and that feels amazing!" He praised shyly, only to whimper as the dragon's grip once again tightened, the sound growing to a moan as he was held in place and he really got to work on him. Unable to help himself, he started to shallowly roll his hips, grinding down on those welcoming lips and tongue. Then Katsuki started to talk again and it was all just shy of overwhelming. He was saying such wonderfully dirty things! How could he say all that so confidently? Honestly, delivering honest praise had been difficult all on its own, but this was so much! Ka-chan was so amazing...! 1

[cryptidchalupa]

The last bits of him that were still sane in vibrant comparison to the rest of him was left to lament over just how quickly this was becoming dangerous. Maybe not in a lethal sense, but he was, bit by agonizing bit, slipping away from the moment and into his own biological need. Tipping back and forth between the taste on his tongue and the mouth on his own aching arousal teetering him on that precipice of his control to the point where he was just about to try and back off for Izuku's sake when Katsuki handed him a way out basically on a silver platter.

It wasn't twice but he certainly pulled on his hair, eager and maybe a bit too much but-- but he needed it if they were going to be successful in this. He wanted to be good, for Katsuki and to Izuku. That stubbornness being the only thread holding him back from throwing the tempting meal of a partner above him on his back and ravishing him until the sun came up and half way into the following day. This had to be good, and they were working with the situation.

Izuku dropping a little more onto him, and even starting to move on his own made him shudder, growling against him with a little more eagerness to his oral attentions, and those noises... Dipping down so he could press at the sweeter core between his folds and try to get at the source of all the slick he got to devour. Tongue dipping ever so slightly into him, feeling the change between inside and outside, and the headier burst over his senses just pushed him further, He concentrated a lot of his effort on getting his tongue into him as much as possible then, especially since it stilled his squirming and made him docile for Katsuki as well. Getting to dip in so far made him giddy, pulling back with a wet gasp and just far enough from Izuku's sex, pupils blown out so wide there was very little trace of red anymore as he stared up at the adventurer.

Izuku praising him on top of everything really struck his self control a little hard. He teased along him with the tip of his tongue, slowly, the most predatory noise he had yet to make rumbling low and deep in his chest. "Katsuki~ If you don't... I might take him. Now/." he admitted, a little bit of a whine after such a dark noise, muffled to a strong thigh. "I'd rather make him cum on my tongue first." as badly as he, instinctually, wanted inside him, either of them really. He needed it bad enough he managed to get footing to actually push himself into his mate's attention, hissing at the way his wet tip slid right over his mouth, luckily he wasn't angled right to fuck himself into the blond's throat or he would have. And that was just about it for his sanity at this point.

"Can I, Izuku?" he breathed, mouth returning to the wetness waiting for it, suckling at his folds again and pushing his tongue excitedly into him just to get it all. He could watch him come undone from here, if he'd allow it. The hand on him moving to slip its way under and join up with his mouth, fingers holding him open for his tongue to leave not one inch unlicked. "You're just as delicious as Katsuki is." he murmured to him, drunk on him, but still vying for the blond with another tug on his hair, wishing so bad he somehow had the ability to put his mouth on both of them at the same time. He didn't have two tongues, but at least he had two hands. "I bet it's even better when you cum."
