Got Virgin sacrifice Izuku/dragon Kai (the Asian kind, not Western) on the mind.
#overdeku
CW: ABO, non-con, underage, Izuku has a pussy, and Kai is a Literal dragon
.
.
Somewhere up the mountains lives a golden dragon.

In the past, the dragon would attack their city until they started leaving virgin sacrifices. Once a year, a lottery was drawn. The unfortunate winner would be stripped, dragged up the mountain, and tied up to meet their fate. No one ever knew what the dragon did with them.

Omeges and betas names were put in the lottery. They claimed it was "fair" since nobles children weren't spared, but everyone knew that they'd put in the commoners names multiple times. Nobles only ever got chosen if one had a troublesome child or the parent had fallen out of

favor with the others.

Legally, marriage wasn't allowed until 16. This meant that any omega or beta starting from age 13 to 16 was at risk. Most parents ensured a marriage at 16, sometimes lacking ones, if it meant their child wouldn't be in the lottery.

Other parents were willing to take the compensation offered for the sacrifice.

Izuku knew he was going to get picked, that his name was likely put in there a dozen more times than any other available person.

With the passing of his father, money between him and his mother was now strained. As a male omega, he wasn't allowed to work without a mate's permission, and Inko struggled to find a nice job a widow.

No one would be desperate enough to take Izuku's hand in marriage.

He knew. He's seen his mother try and fish around to arrange things with other poor families, but none would bite.

The only thing to get Izuku out of this would be to have sex, but that'd ensure a marriagless future.

When his mother died as well, that just about sealed his fate.

He could try and run, but he noticed the way the cities guards watched him. They likely wouldn't let him leave, and legally they were within their "right". An unmated omega wasn't allowed to leave without a family

member at their side.

So, when people gathered in the townsqaure and the name was drawn, Izuku wasn't surprised when it was his called out.

The guards were way too quick to pick him out from the crowd and drag him out.

Izuku didn't fight it. He let himself get pulled along to a small house on the edge of the city where he was bathed in a rush and then dragged out naked.

It was cold this time of the year, and Izuku shivered the whole. Anxiety bubbled up in him, but he tried to remain calm.

He could try and run now as well, but there were four guards, two behind him and two in front. Likelihood of getting away wasn't great, and he'd prefer to walk himself there rather than be dragged along like an unruly dog.

The treck up the mountain took hours. Rocks dug into Izuku's feet, and the sun fought off the previous chill that had settled over him.

No one spoke, not that he expected the guards to be chatty. It was almost a relief when the pillars came into view.

Over time, a proper alter had been set up.

Izuku stepped onto smooth stone and was pulled over to two pillars. He was too short to have his feet touch the ground, arms aching as they were spread and tied above him. His legs similarly were spread and his ankles were tied to the

stone pillars.

His cheeks burned at the undignified position, knowing his entire body was on display to a couple of strangers.

On his stomach, a guard wrote our the character for offering in a sweet smelling, red liquid.

It was a type of dye, if Izuku remembered correctly. He recalled getting some on his hands as a child and not being able to get it off for weeks.

Incense was lit, and then Izuku was alone to watch the sky fall into a pretty sunset. At nightfall, the dragon would come and take

him.

Or, at least it would if anyone had bothered to get Izuku to unclench his fist. He honestly couldn't believe that the small razor blade he had grabbed before he went into the townsqaure was still there.

Although his hands were sweaty, he managed not to drop the small

blade as he maneuvered it to cut the rope holding his hand up.

He almost let out a giddy laugh as the rope snapped, but was a lot more focused on his wobbling body. With his feet off the ground, once that second binding on his hand was cut, he likely was going to fall backwards.

Much quicker this time, the rope was cut, and he quickly leaned forward, rather risking an injury to his hand than his head.

Pain shot up his arm as he hit the ground, praying to God that he didn't just break his wrist.

Taking a deep breath and blinking back a few tears, he focused. The sun wasn't down yet. He needed to free his legs and /move/ before it got dark. Even if the dragon didn't give chase, being along in the mountain woods at night was a terrifying prospect.

Still, better than

being eaten by a dragon.

Once completely free, Izuku tossed the small blade to the side, not wanting the city to ever know he escaped, and then he ran.

Izuku has never been this far up the mountain, it wasn't allowed, but he knew that there had to be a river nearby.

There was one at the bottom, so reasonably it came from up top.

Tracking was harder once water was involved. So, if he swam across a river, no scent trail to follow.

After that, find a safe place to hide until morning.

His best bet would probably just to climb a tree and hope for the best. After that, climb down the mountain, and pray there was a village nearby.

From what he's heard, other places weren't nearly as oppressive as his city. Him being an omega shouldn't be a problem at all.

All he'd need to do is work some odd jobs, get some money, and figure out where to go from there.

To his luck, it didn't take long to find the river. It wasn't too big, but wide enough to spark some anxiety. His wrist wasn't feeling much better, and getting dragged

downstream likely meant a waterfall and/or rapids at some point. The water seemed relatively calm, so Izuku cautiously stepped in.

Once thigh high, Izuku decided he could handle this. If all else failed, he could just walk in the water and follow it down.

But he'd rather get across and put more distance between the altar and his old home.

At first it was fine. But once Izuku hit about halfway, a strong current suddenly yanked him along.

(Tweet limit, tbc)

In spite of his wrist screaming in protest, he desperately tried to get get across. Then something hit his thigh and he went underwater for a moment.

The further down stream he was dragged, the more he started giving up on trying to get to the other side.

Keeping his head above the water was the most he could do as the water got faster and his body slammed against more rocks.

All too quickly, he was flung over the edge of a waterfall. There was nothing he do but shield his head as he crashed into the pool below.

And good thing he did, his arm slamming against something hard as he was pulled under water.

He had to fight for a terrifying minute to get his head above the water.

Taking in a few gulps of air and sputtering out water, he was given no relief.

At the other end of the pool was another fall, and he was still getting pulled right along even if the water wasn't as strong here. His foot hit against something smooth as he made a last attempt to get to shore.

Briefly he wondered if he possibly stand on a rock, but was swept along before he could get any good footing.

As he was pulled towards the fall he made a scramble to climb on top of a boulder sitting at the edge. It scrapped his knees and hands, but to his utter relief, he

managed to pull himself up.

For a good moment, he coughed up water and struggled to catch his breath. If he was cold before, he was freezing now. Every part of his body ached now too, bruised and cut.

Still, he was alive, surprisingly.

When he heard a loud splash of water, he didn't bother to look up until a glint of gold caught his eye.

In the fading light of the sunset, there was just enough to shine off the dragon as it's head rose out of the water.

/So that's what I kicked/, Izuku thought, numb as he

scooted back on what little room he had on the boulder.

It's eyes were gold too, tense and piercing as it stared at Izuku. The dragon's gaze lowered, head slightly tilting.

"You're a long way from the alter, little one."

It's mouth didn't move, but it's low voice range in Izuku's head loud and clear.

The dye markings on Izuku's stomach hadn't been washed away, so clearly marking him as the dragon's little sacrifice.

/What are the fucking chances/

Feelings still numb, Izuku struggled to get to his feet, legs trembling violently from pain and exhaustion. In spite himself, he fixed the dragon with a glare.

Behind him was another drop, one he might not survive.

"Fierce little thing, aren't you?" It sounded almost as if the dragon was smiling, though it's face didn't change. "You're the first one to almost escape."

/Almost/

That thought alone was enough to bring a sharp stab of pain through Izuku's gut, wanting to cry. Why couldn't things go his way for just a day?

Without sparing a glance behind him, Izuku took a couple shaky steps back and fell.

Just before his body hit the water, he was stopped, screeching in pain as teeth dug into his skin.

With ease, the dragon brought him back up the waterfall and through the water of the first one he fell down.

Behind that seemed to be a cave.

It was pitch black for a moment, but torches along the walls burst into flames and washed the cave in a warm glow.

Curling up, the dragon placed Izuku in the center.

Izuku wanted to stand, but knew he had reached the end up his running.

Part of him wanted to reach up and yank the dragon's whiskers and give him hell before he was eaten.

Actually, why wasn't he eaten yet--

That train of thought was cut off as the dragon leaned in close. Izuku eyes squeezed shut as the whiskers brushed against his skin.

Then, he was screaming in pain, body suddenly on fire. He kicked the dragon, even if he doubted it hurt.

For a good moment, Izuku was confused as to what the dragon had done to him until the burning sensation washed off and he felt... nothing. Even without looking away

from the dragon's face, he knew the bruises and cuts were now gone.

"Much better." The dragon purred, clearly eyeing up Izuku's body.

Maybe it didn't want tense and bruised meat.

"Weren't you taught any manners, little omega?"

Izuku bit back an insult, realizing that maybe he wasn't going to be eaten and maybe he shouldn't make this dragon hate him without knowing what was up.

"Thank you, sir," Izuku said softly, looking away from the dragon's face and twisting to hide his naked body from the dragon's gaze. Maybe it was actually a benevolent creature who would free him... but he doubted it.

"What's your name?"

"Midoriya Izuku." Subconsciously, he pressed himself further into the dragon's scales, so warm in comparison to the chilly air and his own freezing body.

"You can call me Kai."

Trembling, Izuku finally had to ask. "Are you going to eat me?"

The dragon huffed, smoke curling through its nostrils. "I don't eat them." It sounded almost disgusted. "Dispose them, though, yes. Humans can be such revolting little creatures."

It's curled tail pulled Midoriya closer.

"But, I'm intrigued."

Izuku flinched as it's tongue flicked out and brushed across his stomach.

"You haven't started begging and bargaining." Its tongue continued to drag up his body, seemingly breathing in his scent. "It might be a bit cruel, but I guess I want to tease you."

A whimper built in the back of Izuku's through, in vain trying to push Kai's head away.

"Already that fierce look has dropped. Are you scared?"

Izuku managed a weak glare, but he couldn't have been more blatantly afraid.

His body shook, unshed tears burned in his eyes, and the dragon could likely smell his fear.

Being eaten or killed was one thing, but being a dragon's little plaything was a whole other order of terrifying. He'd rather it be over in a timely manner rather than torture.

"I-I'm not going to lay here and beg for my life, if that's what you want," Izuku's voice trembled, but he meant it.

Kai sounded amused. "I guess we'll see."

(Tbc)

Izuku curled in more on himself and tried to turn his back. It didn't do much to stop the invasive touching, Kai's warm breath ruffling his hair.

A claw ran down his spine, making the boy shudder violently. It didn't pierce the skin. But it so easily could, and Kai was able to

hurt him and put him back together as many times as he wanted to.

"Humans are such squishy things." Kai mused, claw hooking around Izuku's thigh and forcing it away from his chest. This motion forced Izuku onto his stomach, squirming in vain to sit back up.

"Its a miracle your species has survived."

"There's not exactly a lot dragons around nowadays, I don't think you have room to talk," Izuku snapped back, trying free his leg from Kai's grasp.

In an instant, he was forced flat as Kai's snout pressed onto his back.

His mouth opened slightly and Izuku went very still as a fang poked the back of his neck.

"Watch it, little one." His tongue flicked out again, brushing over the sensitive skin. "Such bold words when in such a vulnerable position."

Izuku continued to shudder, body pricking horribly at the unwelcome touch.

"You're going to kill me eventually anyways." A few tears spilled over, no longer able to keep it together. He was scared and so SO angry. Angry at the events that led him to the situation, at

the people who decided to sacrifice others instead of solving the problem, and angry at the stupid dragon that wanted to toy with him rather than just ending it. There was so much Izuku wanted to do with his life and he never got to chance to do any of it.

The dragon hummed, neither confirming nor denying his intentions with Izuku.

Taking in a deep breath, the dragon finally lifted his head. "I called you an omega earlier because I've learned to associate sweet scents with that title."

Although there wasn't a question, Izuku

assumed he wanted confirmation.

"I am."

Izuku was forcefully rolled over, and he quickly squeezed his legs shut, very much uncomfortable being so exposed to a threat.

"What makes you different than there other kinds?"

"Anatomy," Izuku was quickly growing uncomfortable with this line of questioning. "I can get pregnant, male alphas and betas can't." Well, they could, but Izuku didn't think a dragon would care to understand human gender identity.

"What do I smell like to you?"

Izuku hadn't bothered to register the scent of the dragon. He smelled about what he expected, strong campfires, reptilian, but Izuku supposed if Kai were human, he'd assume he were alpha.

"Probably an alpha, but could pass for beta," he answered honestly, wondering

where the hell this was going, if anywhere. Seems like Kai had just been killing humans for the past century and likely hadn't bothered to learn a single thing about them. Could just be curiosity now that he's decided to hold off from killing Izuku immediately.

Kai tried to nudge Izuku's legs apart. "You can either stop hiding your body from me, or I'll make you."

Face flushing with shame Izuku spread his legs and stopped hiding his chest. Instinctively, he knew this was a presenting position, something only a mate should see.

"Good boy."

More tears slipped out, angry that he couldn't stop them.

"Your scent is getting stronger and sweeter. Omegas like you go into heats, right?"

Izuku's face burned strongly with shame. "Its not a heat, it's a stress response." Omegas, especially when under threat, would often start pumping out pheromones that basically said "nooo don't hurt me" to play on their attacker's senses.

He doubted it worked on dragons.

"I wonder if that's a different smell then."

Izuku wouldn't know what he smelled like in heat given that he's never actually been in heat.

His train of thought was ripped away as the dragon's tongue dragged right across his pussy.

Instinctively he yelped and started kicking, but wasn't able to shut his legs closed as Kai continued to lick.

"I also heard it's possible to work your bodies into a heat."

His tongue was rougher than humans, but not painfully so. Every time it flicked across his dick,

it swelled a little more.

"Its not possible!" Izuku actually wasn't totally sure, and it didn't want to test it. He tried rolling away and getting to his feet, but his healed body didn't mean the exhaustion was gone.

His legs wobbled, having nowhere to really run to.

Easily enough, Kai sandwiched Izuku in his tail, smooth scales against his stomach and a heavy weight on his back.

"I'm curious and would like to make sure."

Izuku couldn't see behind him like this. His fists uselessly hit

Kai's tail as the dragon continued to stroke his tongue over Izuku's pussy.

Little sobs and moans escaped Izuku, still struggling despite knowing how useless it was. He could feel a climax build in him. It only took a few more strokes until Izuku was crying out and shaking hard.

A couple more licks followed, forcing Izuku to carry out his orgasm a little longer.

When Kai finally stopped, Izuku's whole body went slack, panting and trying to blink tears out of his eyes.

"You taste sweet too," Kai mused. "Omegas really are just humans little whores."

Izuku weakly shook his head despite knowing it couldn't be seen.

The dragon's tail slid off Izuku's back and he was pulled back to the center of the coil.

This time, he didn't stop Kai from pressing his snout between his legs.

"I want to see your face. I'm still not convinced, your smell is starting to change."

Izuku wanted nothing more than to hide.

His body was still so sensitive as Kai's tongue swept over his pussy again. Then his tongue started pressing in.

"No!" With weak hands, Izuku tried to bush Kai's face away. "N-not there, I've never-- a-ah-" He slumped over Kai's snout as his tongue forced its way inside his hole.

A sob forced its way out of his mouth as that tongue steadily wiggled its way inside of him.

His body was meant to stretch, and it likely would've been a lot easier if he wanted this. But he didn't it, he wanted it out. All he could was try to steady his harsh breathing and relax his body, knowing Kai would keep pressing forward regardless of Izuku's limits.

It hurt. But what could he do? The worst that he could in retaliation was to try and dig his fingers under Kai's scales. It probably was only an itch of a sting to the dragon. It gave Izuku something to grab onto at the very least, to ground himself.

"As cute as it is for you to

be holding onto me," he didn't sound like he found it particularly cute, "I said I wanted to see your face. Lay back."

Izuku obeyed if only not to be forced down. His legs instinctively spread further as he did so, trying to alleviate the tight pressure from being split

too far.

Kai at the very least seemed to know when not to press his tongue any deeper, but Izuku was sure it was still far deeper than any alpha dick would've gone.

His next orgasm left him sobbing, slick squirting out of him to add to the wet mess slowly forming under him.

Kai still didn't stop, but slowed the pace as Izuku shook and sobbed, so determined to not start begging. He just had to hold out until the dragon got bored.

Like this, Izuku could really feel the texture of Kai's tongue as dragged up and down.

It was hot too, borderline uncomfortable.

With every out stroke of the tongue, it rubbed over his little swollen cock, drops of omega-sweet cum mixing with Kai's saliva.

His third climax hit just as hard as the previous two, thighs squeezing tightly around Kai's snout. His voice cracked this time when he screamed.

Izuku tried to ignore the feeling of mixed fluids that drooled out of him when Kai's tongue slid out of him.

"Humans don't have a lot of stamina. You look ready to pass out."

Izuku closed his eyes as his chest heaved, too tired to wipe the tear tracks off his face.

"You stretched more than I thought you would, but I think it could go further."

Ice prickled over Izuku, eyes snapping open. "I-I can't, no more." What else could Kai even do? Kai's cock had to be physically impossible for Izuku to take, even by the most generous standards. "You had your fun, please just end it."

"I don't believe I have, though."

Kai seemed to consider things for a moment, eyes looking over Izuku. "You're small, even for a human."

Maybe he was sensibly realizing that there was literally nothing Izuku could do to please him in return and would free him (preferably) or end him.

But of course, there was a way around it.

Kai's body shrank some. Still, much bigger than Izuku, but no longer several times thicker than he was.

This also meant that the tail supporting Izuku's body was gone, and he was left on the cold hard floor.

For a moment, that is. It didn't take long for Kai to wind him around Izuku. His snake like body lifted Izuku off the floor, a thick coil under his stomach and curling over his shoulder. It left his arms awkwardly dangling, unable to hold onto anything.

Izuku wiggled uncomfortably, trying to deny in his head what was about to happen.

It was the end of Kai's body that curled around him, leaving his upper half free to comfortable turn and watch Izuku. "This should be small enough."

When Kai's body ever so slightly shifted forward, smooth scales dragging over Izuku's skin, he felt something press against his backside.

"No!" Izuku slammed his hands down on the tail wrapped around his stomach, unable to twist and look.

It might've been a blessing in disguise to not see what was going on. Adjusting a few times, he could feel something slippery pressing against his wet hole.

"C-can't you turn into a human?" Izuku asked, desperately looking to Kai's face. In some stories he's heard about

dragons, they could turn into men and beautiful women. Maybe Kai could do the same.

"I already don't like making myself smaller for you, so I'm certainly not going to make myself /look/ like one of you." There was a slight crinkle on Kai's face, disgusted.

"I thought you weren't going to beg?"

Any of Izuku's pleas immediately died as Kai started to push his cock into him. It was smooth and easy at first, but then a few inches in, there were ridges on his cock, and each ridge forced Izuku open wider.

Izuku wailed as that pulsing heat was pushed into him, nails scraping against the ground as he desperately tried to cling to something.

Kai took a little pity on him with that issue, moving his head closer so Izuku's chest has something to press into and his arms something

to hold as he sobbed.

Eventually, Izuku hit his limit. The stretch was too much, pain a little too sharp. "Too big!" Izuku yelped, legs uselessly trying to kick back. "I can't, please, I don't want it to hurt, please please--"

The press in stopped, and Izuku breathed out

in relief, vision so blurry from tears.

"So good, little omega," Kai praised. "But we're not done yet."

He didn't push in further, but he started to fuck him. The slow roll of his thrusts should've been easy to take, but the added in ridges and stretch left

Izuku writhing as much as the restraint would allow.

"F-fuck," he gasped out, able to feel the drag of Kai's cock against his stomach. The tail pressed against him left him keenly aware how deep the dragon was fucking him.

He swore he could feel Kai's heartbeat in the pulsing of his cock, a weird stimulation he couldn't fully comprehend on top of everything else.

At least Izuku was no longer cold, body practically on fire as Kai fucked him.

"I can see now why other species fancy the omegas of

your race," Kai said, voice as steady as always despite the steady puffs of breaths Izuku could feel against his body and his quickening heartbeat.

"Your greedy little hole will take anything that's put in it."

Izuku's face felt hot with shame. "Yo-you gotta use me be-because no one else would want to sleep with you."

Kai let out a low growl, slow thrusts suddenly becoming a lot harder and jerking Izuku's body.

His broken cries and moans were cut short as Kai slipped his head out from underneath him and instead shoved his tongue down Izuku's throat.

The omega gagged and whined, trying to shove Kai's face away to no avail.

"The only thing you're good for is being a cock sleeve."

Senses so overwhelmed, it took Izuku a moment to realize Kai had shoved the cock the rest of the way in, able to feel the brush of Kai's under belly against his ass.

Kai kept Izuku like that for what felt like hours, gagged as his pussy was pounded hard.

Izuku came a couple more times, ashamed as that extra slick was fucked right out of him with noisey squelches.

Finally, slipped his tongue out of Izuku mouth, letting the omega cling to his head once again.

"That's it, little one, you're taking it so well," Kai cooed, sounding a little strained.

A few more thrusts and his golden eyes squeezed shut, coming right into Izuku.

The omega squealed, voice cracking horribly as Kai's hot release was pumped into him.

"Too full," Izuku whined, voice hoarse. "Kai, p-please pull out." The pressure was getting too intense, making Izuku sob as genuine took over him. "Pull out! I can't, I-I, please."

Kai pulled out and his cum was quick to follow.

Izuku's body was dropped to the floor, shaking and panting as Kai's body went back to full size. Spurts of cum continued to cover his body for a moment longer until the dragon's orgasm passed.

Izuku was too exhausted to care, surprised he hasn't already passed out. The sticky, wet warmth coating most of his lower back was not enough to keep him awake.

Being picked up and dropped into freezing water was, though.

His eyes were open, but he barely registered a thing

as Kai gently cleaned up his body.

As soon as he was pulled out of the water and back in the center of Kai's curled up body, he was out.

Izuku wasn't sure how long he slept. He barely opened his eyes when he did wake up, so cozy and warm.

Slightly shifting his body brought over a wave of pain, and he groaned softly as his eyes opened.

His blood ran cold as he was met with gold scales.

Right. He was now a dragon's sex toy.

It was unnerving to look up and see Kai silently watching him.

It was daytime now, some sunlight streaming through the waterfall.

"You're not going to let me go, are you?" Izuku said, voice cracking sorely as he spoke.

Kai's head tilted slightly. "If you had a toy you could pleasure yourself with, would you throw it away?"

Izuku's eyes burned, but he was sure he had cried all he could the night before. "I'm not a toy."

"But I can be reasonable," Kai continued.

"Stay with me for a year, until that next sacrifice comes along, without fighting against me or trying to run away, and I'll free you and give you treasures. You'll have enough money to get a new life somewhere else."

Either way, Kai was going to get what he wanted... so better

off taking up the offer and ensuring his eventual freedom. Right?

"If... if I stay, you can't excessively hurt me," Izuku says, as if he has any real power in this situation. "I know it's going to hurt no matter what, but... don't cut, bite me, and hurt me with your powers."

Kai looked a little amused. "I'm more interested in getting you to enjoy it. So, promise, I will try not to cause excessive pain."

Izuku fell silent for a moment. "And I just have to take your word on all this?"

"I keep my word. Hold your end of the deal, and I'll hold mine."

(END)

(If you enjoyed it, consider leaving a tip :D)
ko-fi.com/eeksh

Okay but bonus in case you're wondering how it all ends: Kai is canonly honest, so he does in fact let Izukj go and gives him treasures to rebuild a life.

But I'm always weak for Kai accidentally getting attached to Izuku.

Ends up becoming willing to shift into a human form if it means he can stalk Izuku and try to worm his way back into the omega's life.

And after being alone with Kai for a year, Izuku himself has some sort of fucked up attachment to him.

So, do with that what you will :3c
