Work Text:
The grass is damp against his hands and knees, but the chill does nothing to diminish the warm red flushing his skin. They're out in the middle of nowhere, yet Izuku can't help but feel paranoid that someone is going to stumble across them anyway.
"This'll work." Izuku says shakily, mostly trying to convince himself. Charmeleon huffed, hot breath steaming from his nostrils and dissipating into the air. Even as skeptical as he clearly was, he didn't protest, sharp eyes watching as Izuku shifted nervously in place.
They had tried everything. Literally everything. This was their best bet and they both knew it. Days of Izuku stretching his hole, all for the chance that maybe, just maybe Charmeleon could finally evolve into Charizard.
Dozens upon dozens of battles, sleepless nights training, endless research. Nothing had done the trick, and it had been years now. Charmander had evolved into Charmeleon within a mere month of Izuku choosing him as his starter, and the both of them had been invigorated and overjoyed by the mere notion of what that meant. They'd assumed that it would only be a matter of time before his evolution into Charizard hit.
It's not like they don't have the bond for it. Charmeleon is his best friend, and Izuku dotes on him every day of their lives. It's been years of working towards what now feels like an impossible goal, but they're closer than ever. Their relationship is unlike anything Izuku has ever experienced, beyond anything he'll ever experience again.
That's why he doesn't get it. They've put in the work, they love each other, they've gone through countless hardships. It's been nearly ten years. Charmeleon should've evolved. He wanted it and Izuku did too, and scientifically that should've been all it took.
"Char." Charmeleon frowned as Izuku lowered his upper half down, cock bobbing embarrassingly between his legs. Charmeleon had seen him naked before, but not like this. "Char!"
"I know! I know! But we've gone through every other journal, and we've tried them all! This is the only thing left." Izuku blustered out, face reddening. He twisted to peer over his shoulder, dark curls falling in his pleading eyes. Charmeleon huffed again, more of a sigh than anything.
Izuku didn't have any grand plans to run off and battle every Pokemon gym in the region. He had no desire to climb to the top of fame, to rest on a pillar of strength envied by the rest. That wasn't why he was doing this. No, what Izuku wanted was deeper than that.
The Pokemon Rescue Frontier was a group of— of heroes, really. They saved Pokemon and people alike. They fought villains who wreaked havoc with their teams, who thrived off chaos. Izuku had wanted to be a part of them since he was a little boy, and Charmeleon had always shared that passion with starry eyes and endless determination.
The only problem is that it's a requirement that you have a fully evolved Pokemon to join. Izuku checks every other box. He and Charmeleon have a winning battle streak a mile long, they're close enough that they can practically read one another's minds, and they're both in excellent shape.
The only thing missing is the evolution. And based on Izuku's deep-dive into the forums, this was a way to get it.
"Char." Charmeleon was close enough that Izuku could feel the heat radiating off of him. Izuku buried his face in his arms at the disparaging tone.
"We talked about this. The only thing left to do is try. Y-You're my best friend. It doesn't have to be... be strange. It's not a bad thing. Lots of people do it!" Izuku's own face was practically steaming, it was so hot. The lube dripping from his hole made the experience all the more humiliating.
Charmeleon made another uncertain noise, but Izuku knew him well enough to know he wasn't actually all that put out, just worried. They both knew this had to be done. It... It wouldn't be so bad. They do everything else together, so what if they have sex on top of that? It's just the one time. It doesn't have to mean anything.
"It's just us deepening our bond. We're doing this for you, so you can evolve. I know you want to save people and Pokemon just as much as I do," Izuku forced himself to look back up. He gave his ass a hesitant shake, grinning embarrassingly. "So come on! Let's do this, Charmeleon. I believe in us. This is going to work!"
The flame of Charmeleon's tail flared, his eyes sparking with a bit more certainty now. He stepped closer, hands finding the round of Izuku's ass. They were scalding hot as always, reddening the skin there with just a touch. Izuku hoped this wouldn't hurt beyond measure, but even if it did...
Izuku gave a shy but determined nod, and Charmeleon grinned, teeth sharp. They had to do this. This had to work.
The forums Izuku had found weren't public knowledge. They're something he'd dived deep for, digging through the bulk of false information and superstitions to find. Izuku hadn't believed it when he first saw. His face had flamed red and he'd slammed his laptop shut, him and Charmeleon swiveling to look at one another with wide eyes.
Amongst the old wives tales that weren't truly effective, however, it stood out. Not just because of the taboo of it, but because... because of the videos.
It worked. Most of the videos were grainy and poorly filmed, but there were too many for at least a few not to be real. The closer a Pokemon was physically and emotionally to their trainer, the more likely it was to evolve. He and Charmeleon had the emotion part down, but there was nothing bodily closer than sex.
It would deepen their connection. Charmeleon just needed one last push to get him to evolve, Izuku was sure of it. And this push is it! It's not dangerous. Even if it's not talked about, people and Pokemon have coupled together for centuries as a way to get closer! Culturally, it used to be the norm!
It'll be fine. Izuku has stretched himself, has spent days digging his fingers into himself and keeping his hole slicked. Today is the day. They're both ready. If something is going to give, it's going to give now.
Charmeleon's nostrils flare. Izuku doesn't have to look back to know his cock is peeking out from its sheath. It's not like a human's dick, instead tapered at its tip and with a large, bulbous knot at its base. That knot was the real reason Izuku had been stretching himself so wide. If they were going to do this, they'd do it all the way— that knot included.
"Come on." Izuku urged, quieter than he meant to, "come fuck me."
Charmeleon made a low growling noise, and Izuku felt something burning hot nudge against his dick. He swallowed a moan at the sudden sensation, tensing without meaning to. Charmeleon's cock was about the same length as his own, but it was slicker and fatter. Izuku felt it slide up to rest between his ass cheeks, the heat warming down his spine.
Charmeleon's claws dug lightly into his hips, not quite tight enough to break the skin but close enough to sting. Izuku could hear his Pokemon's breathing increase, growing labored as he gazed down at Izuku's arched back and raised ass. The tip of his fat cock kissed Izuku's hole, hovering.
The anticipation made Izuku swallow heavily, but he didn't tell Charmeleon to stop. He pushed back lightly instead, encouraging. His own cock was achingly hard with anticipation, already shamefully leaking precum. Charmeleon had been nice enough not to chortle at him for it. In a way, he was probably excited too.
"Char." Charmeleon said, as if promising to go slow. And just like that, his cock was pushing in.
Izuku gasped at the sensation, eyes rounding and fingers digging into the grass beneath him. He can't say for certain what he expected. A part of him had assumed it would hurt, that it would be like an iron poker fresh from the flames stabbing into him. He'd thought this would be a grueling process, something he'd have to bear with gritted teeth and tears in his eyes. A trial.
Charmeleon's cock was hot and impossibly heavy, but what Izuku felt was far from pain. It filled his hole entirely, stretching him past what his fingers had. The burn of it chased away the ache, his muscles relaxing around the heat as Charmeleon slowly pushed his way into bottoming out.
It was a downright sinful sensation, one that consumed him entirely. Izuku could feel another dribble of precum drip from his aching cock as that heat pressed directly into his prostrate. Charmeleon grunted, claws pinching harder into his hips unconsciously. Izuku opened and closed his mouth, trying to find the breath to speak.
It was so hot.
It was so... so good.
Good like pleasure sparking all the way down to his fingertips. Good like he wanted to grind back to seat it deeper inside of him. Izuku couldn't help but deliriously think that fuck, they should have done this sooner.
"O-Oh. Oh that's, that's— that's so good." Izuku gasped out in surprise, stunned by the revelation as Charmeleon gave his constricting walls time to adjust. Izuku trembled, fighting to keep a clear head.
"Char." Charmeleon seemed to agree, strained, but didn't seem to need anymore encouragement. Slowly, agonizingly, he began to move.
The drag was impossible. Izuku felt his eyes roll back as Charmeleon slowly worked himself back before smoothly sliding back forward again. The motion was careful, his iron-grip on Izuku's hips preventing him from recklessly slamming back onto the heat.
Izuku could feel his orgasm building. Izuku distantly wondered again why they hadn't tried this before. Izuku loves Charmeleon. He's Izuku's entire life. He's had him since he was just a child and this— this is insane. Izuku's never going to be able to fuck anyone or anything else again.
Unable to stop himself, Izuku let his mouth fall open, his moans escaping him. They were quiet and breathy at first. Whimpers that made Charmeleon's claws lightly puncture his skin, that made his slow thrusts stutter. Izuku sunk into the lazy heat, the rhythm. Any embarrassment from before was long gone.
"You... You probably h-have to go faster. If you w-want to evolve." Izuku moaned out. "You have to f-fuck me harder. Faster, god, please go faster. Faster, Charmeleon, please just—"
Charmeleon drew out and slammed into him. Izuku's vision went blank in the same instant, eyes rolling back and mouth soundlessly falling open. He knew he was panting like a bitch in heat, but he didn't care. He didn't care that he was moaning on his Pokemon's cock like a mindless whore, or that he was shaking so hard that even Charmeleon couldn't keep him from jerking back to meet his thrusts anymore.
The heat felt too good. Cum sprayed from Izuku's cock, erupting and painting the grass beneath him. His moans echoed around the forest, and Izuku knew he probably made for a debauched image right now. Him, moaning like a wanton whore under his own Pokemon.
Charmeleon seemed to know how to hit all the right spots. He targeted Izuku's prostate with single-minded obsession, ramming into it brutally, losing the ability to restrain himself. The heat of the cock inside him was nigh burning, but it was so, so good. Even as it got hotter and heavier inside of him, Izuku didn't care.
It was wild, animalistic. Charmeleon growled furiously, roughly driving into him. Even after Izuku came a second time, that didn't stop him from flipping Izuku around onto his back and lifting his legs up so he could thrust in even deeper.
"Good, good, so good. S-So good." Izuku babbled mindlessly, drool seeping out from between his lips. He reached his arms up, mouth open and panting, eyes hazed over with the aftershocks of his own orgasms.
Charmeleon's tongue was hot and much longer than his own, delving furiously into his mouth. Izuku could feel his expanding knot ramming into his rim, and he moaned long and loud as it threatened to pop in amidst his best friend's furious fucking. His back arched obscenely, and he cried out as Charmeleon's hands found his nipples and tugged.
Teeth bit down on his shoulder. Izuku came again, his cock spurting weakly against his own stomach. A scream left him as Charmeleon's knot popped into him and locked itself in place. And then—
And then the cum.
Izuku's eyes rolled back, his mind going blank as searing heat filled him to the brim. His ass worked to milk the cock inside of it, as if he'd done this a million times before. Charmeleon let out a low rumble, teeth unlatching from Izuku's shoulder and eyes fluttering with pleasure as he emptied into his trainer.
Izuku spasmed, body falling limp. Pleasure and overstimulation were tingling through his overheated body. He could feel every drop of Charmeleon's cum inside him, so hot and thick. His cock was still pulsing, jerking forward every so often and punching air out of Izuku's lungs.
Another moan left Izuku as Charmeleon's cum finally stopped emptying into his insides. He felt his Pokemon still as Izuku panted, coming down from the high. He felt boneless and so good that he wished the moment would never end. He closed his eyes, breathing deep to try and catch his breath and get the ability to think back.
Charmeleon let out a sudden noise, grip on Izuku's hips loosening. Izuku let out another moan, eyes rolling back again as his weight fell, the knot pulling at his rim furiously as gravity worked against them. Charmeleon stumbled as he was dragged down too, letting out a noise of distress.
"Wh-What—" Izuku moaned, cracking his eyes open. He froze at the sight of his Pokemon's panicked face, his eyes wide as he continued to try and tug his cock from Izuku's hole. He was—
He was glowing. He was evolving! It had actually worked! Izuku gasped, propping himself up on his elbows. Excitement flooded him, his face brightening and a grin stealing across his face. They had actually done it! They... They...
"Char!" Charmeleon grunted with exertion, and Izuku's smile dropped.
His cock. Charmeleon's cock was still inside him.
"O-Oh. Oh, no." Izuku realized. Charmeleon let out another noise of distress, looking near tears as he futilely tried to pull back. "I-I'll break, I'll break! Charmeleon, just hold on! Hold on f-for just a second!"
Izuku's pleas were lost. It was too late and they both knew it. Izuku could only watch in horror, closing his eyes against the blinding light as it flared brighter and brighter. He was going to die. He was going to die—
It was so fast he barely had time to process it. The cock in him vibrated so hard it made Izuku's head fall back, his back arching again. He could feel it pulse again and again before it gradually began to expand, like Charmeleon was still trying to fight against it. And then... that was it.
It grew. Izuku screamed as it stretched him, growing hotter. His eyes bulged, head thrown back and back straining as Charmeleon inflated right inside of him. His stomach bulged obscenely as the cock expanded. It crushed his prostate in seconds, rearranging his guts.
Izuku blacked out as he was dragged up, hanging off of Charizard's massive cock like a sex doll. He could barely breath, not enough to scream. He was frozen and helpless, limp as it filled him. It felt like it went on forever, tearing him in two until the entire outline of it was visible through his skin.
He felt like nothing more than a toy, hazy with pleasure and shock as more cum weakly spurted from his broken cock. Cum and piss sprayed from it, leaking down Izuku's hung upside down body as Charizard tried to find his footing after the evolution. Izuku choked, shaking wildly all over.
It felt— it felt. It was too much all at once. The pain and pleasure mixed in equal regard, and Izuku wheezed as Charizard's second cock formed, slapping down across his torso. It crushed his cock and balls against his body, sandwiching them and making Izuku convulse all over again, drool slipping from his gaping lips.
Broken. He was broken. Charizard's second cock was nearly the entire length of him, and Izuku could barely process that there was another one the same size inside of him. He looked pregnant from it, blood rushing to his head as he continued to obscenely hang off the cock he was speared on.
It felt good. It felt so good. It felt amazing, and it hurt, and Izuku wanted more, and he wanted it to stop. He could hardly form a thought, even as Charizard let out a roar that vibrated through his entire body and sent him coming again. The sweaty musk of his second cock made Izuku moan, even as his Pokemon reached down and pulled him back upright.
The new position only made the cock sink deeper into him. Izuku's head lolled, unable to form words or to even move. It was all too much. He was broken. He was sure he was. His abused cock still stuck between his own body and the other cock he was pressed to, its massive tip right by his face.
Charizard gazed down at him with sharp red eyes. It had actually worked.
"Ch-Char--" Izuku couldn't help but grin dazedly at the sight. Charizard reached down, wrapping a clawed hand around him to lift him up.
Izuku felt relief distantly fill him, even as he uselessly flopped to the side. He'd lost control over his body entirely, incapable of doing more than twitching wildly. His ass felt destroyed, pleasure still rolling in shocks through his body. Charizard slowly, carefully lifted him up.
That should've been it. That should've been all. But then Charizard... dropped him.
It was so sudden and unexpected that Izuku didn't even realize what was happening at first. His stomach ballooned out again as the cock pushed back into him, carving out its own place, forcing his body to remember its shape. Izuku's wide, teary eyes met Charizard's piercing scarlet as the fire type grinned at him with all teeth.
Izuku wanted to tell him to stop. That he was going to break for sure, but he couldn't. Charizard kept a firm grip on him, moving him up and down, fucking furiously into Izuku's body. Izuku felt his mind go blank with pleasure as he came again, not sure if anything even came out this time as he was fucked within an inch of his life.
The heat was overwhelming. Izuku continued to convulse, his tongue out as he panted, a heavy flush over his cheeks as he was stretched over and over again. Charizard used him like he was nothing more than a handheld fuck toy, pumping him up and down. Even if Izuku could move, there was no escaping this.
He should hate it. He should be disgusted and affronted, but it's too much. The pleasure. Izuku wants more. He wants more, he wants to be as close to Charizard as possible. That's why Charizard is doing this, right? That's why he bit him, that's why he's fucking him now.
Izuku can take it. He and Charizard were made for one another. Izuku was built to take him. He's ruined for any other cock, and this one is so good. Big, meaty, filling every nook and cranny inside of him. Izuku cums again.
"Y-Yes, yes." Izuku thinks he says, but it's hard to tell. Charizard roars either way as Izuku reaches a fever pitch of pleasure, so overwhelmed with it he loses the ability to perceive anything but the cock inside of him.
The knot that locks into him is much bigger than the last. Izuku screams with what little breath he has left as it pops in. Charizard's other cock, which had been sliding the length of his slutty, limp body, cums too.
Izuku's belly rapidly expands. A sick parody of pregnancy, his pokemon's seed filling him even further to the brim. Izuku inflates, eyes wide and unseeing. Something bubbles up his throat, and Izuku chokes as salty cum sprays so far into it him it escapes the only place it can— past his lips.
The other cock cums thick globs of white that coat his entire body, painting his form. Charizard releases him, letting Izuku stay speared, suspended on his cock like an adornment rather than a person. Izuku's belly sloshes with seed, his whole body soaked with it as Charizard's other cock continues to spray it across him.
Izuku's body spasms inhumanly, his stomach cramping but the haze of orgasmic pleasure enough to overshadow it. Charizard lets out a triumphant huff, plopping down hard. Izuku's body jostles on its place still impaled, though he barely registers it.
There's no telling how long he's stuck on that monstrous cock. The flood of cum in him stays hot, constantly warmed by the cock inside him. His ass is destroyed, but it worked. It actually, really worked.
Izuku's going to want to drool over these two cocks every day for the rest of his life. He's going to want Charizard to fuck his gaped out hole because no other will be able to measure up. Izuku already knows he's going to become a slut for this. That he's going to beg Charizard to breed him again, because if he survives this, it'll be irresistible.
But he got Charmeleon to turn into a Charizard. And to him, that makes it more than worth it.
