A New Kind of Evolution

"Dear Mr. Haddock,

I am delighted to inform that you have been selected to participate in a special dragon training contest. This contest will hold dragon trainers from all over the world and see who has trained their dragon to be the very best, like no one ever was.

The contest will be held at [Date/Time] at [Stadium on an unmarked island]

We hope to see you there."

That was the note that Hiccup was given as Terror Mail days ago.

Excited and intrigued since Hiccup didn't know there were dragon trainers, much less dragons, in other parts of the world, but any chance to learn something new is always a pleasure in Hiccup's mind.

However, when he arrived at the stadium mentioned and entered, he noticed something, the stadium was practically empty except for himself and the other Dragon Riders and Dagur.

Hiccup yells out, "Hello? We're here for the dragon training contest!"

Snotlout then asks, "Uh…what dragon training contest? I'm here for the fitness competition."

Hiccup raises a brow. "What? Let me see that." He snatches the note from Snotlout's hand and, sure enough, it tells him of some fitness competition.

Fishlegs adds, "I thought this was a growing contest." He says as he holds up a potted flower.

Astrid adds, "I thought this was an axe throwing contest."

Ruffnut adds, "We were just told that something exciting was going to happen." Tuffnut nods in confirmation.

Hiccup then states, "Ok, something is definitely going on here."

Unbeknownst to the Dragon Riders, standing in the stadium's viewing booth, stood a man with black hair wearing a black suit that had a badge with the letter R in gold along with some other people. "Well?"

One of the workers replies, "The riders are all here and the toxin is loaded and ready."

The man adds, "And their dragons?"

The same worker replies, "They have been sedated as requested, sir. We are waiting for your command."

The man nods. "Proceed."

With the flick of a switch, the ground of the stadium shakes a bit as part of the floor lifts up, revealing a four sided pipe that started expelling a purple gas, catching the eyes of the riders. "What is that stuff?" Hiccup asks as he covers his mouth and nose. "Don't breathe it in, guys!"

However, since he was standing right next to the pipes. Tuffnut got a sniff of the gas and started feeling light headed. "Oh…what's…what's going on?" It was then that he felt his mouth tightening and expanding outward, forming a sort of red beak. "Wh-what's happening to me?"

"Your guess is as good as mine!" Snotlout yells as he breathed the gas as well and his mouth expanded too, but was also starting to turn orange.

The other riders scramble as they cover their faces and try to find a way out of the stadium. Hiccup looks up and yells out, "Toothless?! Toothless, where are you?" but got no response, making Hiccup groan. "Where is Toothless when I need him?"

Tuffnut looks down and sees his hands mold together to form grey, three digit hands and the sides of his arms seemed to be heating up, in a good way, to the point where they seemed to be expelling fire which burned right through is shirt.

His hair became a more sandy color and extended up to form two long ponytails, his torso and upper legs took on a bunch of red feathers, his lower legs developed yellow feathers and his feet retracted into his ankles, merging to form 3 talons that were covered by the feathers of his lower legs.

Finally, his pants bulged out as his junk expands and bursts out of his pants, revealing a set of large, red balls with a 10 inch tapered cock. Once all that was complete, Tuffnut yells out, "Blaaaaaaaaaaaaze! Oh, fuck that feels good."

Snotlout, on the other hand, continued to shift as his skin turned orange, his stomach expanded and formed a yellow patch around his torso, his back grew a set of wings and his rear sprouted a very long tail that seemed to have a flame on the end.

His hands also merged to form three digit hands, his face molded as his hair retracts into his head and his head grows two horns, his feet bulk out to form very thick thighs, his ass cheeks expand out to become just as large and soft, and his cock grew to about 11 inches.

Looking down, Tuffnut, in his red bipedal chicken form, looks down to Snotlout, who was lying on the ground in a mess of whatever parts of his tattered clothes were still intact, and notices his new soft, large, plush, orange ass cheeks and comments, "Snotlout…I never noticed how…hot you were."

Snotlout raises a brow to the statement as Tuffnut leans in and pushes his red beak into Snotlout's new, tight dragon pucker, pushing his tongue inside the waiting pucker making his Snotlout's tongue hang out from pleasure. "Oh, god that feels good!"

Not wanting to wait a second longer, Tuffnut rips off whatever bits of clothing were remaining, rubs his new cock along Snotlout's ass and pushes it right inside, finding the tapered tip to slip in like a glove, making Snotlout groan deeply. Snotlout raises his thick, orange leg high into the air to give Tuffnut better access as Tuffnut pushes his cock in and out at an increasing pace.

Having looked through the cloud of the gas, Fishlegs spots the two of them in action and comments, "They're THAT far gone? Wh-what even are they?"

Hiccup replies, "I think I've heard of those creatures before. They're called Pokémon and they're from a land far away from the archipelago. I believe Tuffnut became what's known as a Blaziken and Snotlout is what they call a Charizard."

Fishlegs adds, "Do these Pokémon always have to fuck like this?"

Hiccup replies, "You ask me like I've actually seen these creatures before. I…I don't think these guys can be helped now, so let's just go."

Fishlegs replies, "Uh, go on ahead, I suddenly feel…so…sleepy…" he flops down onto the ground on his stomach as his face expands outward, his eyes close to the point where they become full on slits and his head becomes mostly blue minus his face which stayed a sandy color.

Meanwhile, the Blaziken, Tuffnut, continued to fuck Snotlout's Charizard ass and making him feel even better.

Tuffnut flips Snotlout onto his back and notices a few things, one his orange balls were huge, bigger than Tuffnut's head even, and two, Snotlout's cock seemed to be leaking pre-cum like a broken faucet, getting the clear fluid all over himself and the ground below.

Snotlout was completely caught up with how good having Tuffnut fuck him felt that he didn't even notice his own cock was bobbing in the air, wanting someone or something to wrap around it. Licking his lips, Snotlout leans in and slips his cock into his mouth, guzzling down his own pre and savoring the taste and the heat that his cock was emitting.

As Tuffnut thrusted in, it would push Snotlout's Char-fuck pole down his throat, and Tuffnut ended up thrusting faster and faster, making flames extend from his wrists as he increases the speed to the point where he almost seems to be a red blur.

In no time at all, Tuffnut thrusts one last time and dumps the contents of his red balls into Snotlout's ass, causing Snotlout's already chunky stomach to expand even more and making Snotlout cum as well, making him fire his own white, creamy load down his throat to meet with Tuffnut's load in his stomach.

Once finished, both Tuffnut and Snotlout pull out and Snotlout lies back with his three digit hands on the back of his neck as Tuffnut scooches down to fondle Snotlout's large, orange balls and lick up the cum that was dripping out of his ass.

While that was going on, Fishlegs was continuing to transform as his hands merge into blue paws, his stomach expanded to the point where his mid-section busts through his clothes, revealing an all blue, very round back, his feet mold into paws, his balls become blue and expand to the size of grapefruits and his cock extends to about 9 inches in length and 2 inches in girth.

Dagur, who was previously kicking at the door trying to get it open to no luck, runs over and spots Fishlegs in his massive, blue form and appeared to be sleeping peacefully. Dagur comments, "Fishlegs…when did you develop such a big…fat…sexy ass?"

Dagur also notices that Fishlegs's ass was still covered by what little bits of his pants remained, so he rips the pants open, revealing two blue, very thick cheeks sandwiching a donut ring of a pucker. Licking his lips, Dagur leans in and begins licking Fishlegs's ass from just above his balls to the very top.

It was then that Dagur noticed something very odd, from his back seemed to sprout an additional set of very muscular arms and his skin was turning a light grey, his mouth developed very puffed, yellow lips, his hair retreated and three half-rings grew on top of his head as his muscles inflate and expand to the point where his clothes also tattered to bits.

Dagur, the now Machamp, also looks down to see that his cock had split into two and each cock grew to about 12 inches in inch thick length from tip to base. Stroking his cocks as bit with his lower arms, Dagur notices that Fishlegs's hard cock was dribbling pre onto the ground and looked all too appetizing, so Dagur flips Fishlegs onto his back, an easy feat with all of his new muscles, and lies on top of Fishlegs, pressing his grey, muscular ass against Fishlegs's face.

Fishlegs licks his lips and reaches his tongue up, licking up Dagur's ass and enjoying the musky taste while Dagur begins to lick Fishlegs's blue cock, pausing a moment as the pleasure on his ass was just that good. Dagur opens his mouth wide and pushes Fishlegs's cock into his mouth, finding that, even with his big mouth, Fishlegs's girthy pole could still just barely fit into his mouth.

Unable to contain himself at that point, Dagur moves his face down onto Fishlegs's cock head, bobbing the fat tip, while he reaches his lower right hand down and fondles Fishlegs's equally fat and heavy balls while moving his upper right hand down to poke at and prod Fishlegs's asshole. Fishlegs then picks up a very strong scent of musk coming off of Dagur's grey balls, so he has Dagur move up a bit so Fishlegs could slip Dagur's balls into his waiting mouth.

Miraculously, the Machamp, Dagur, was able to fit all of Fishlegs's fat cock down his throat, right down to the fat, blue balls and the Snorlax, Fishlegs, couldn't help but move back up to Dagur's ass and continue to lick it. Even though Fishlegs's eyes were shut, he could still sense where he was going and what he was doing.

Deciding how much he loved having his ass played with, Dagur moves his ass away from Fishlegs's face and turns around before sandwiching Fishlegs's blue, girthy cock between his grey ass cheeks. Dagur rests his lower arms on Fishlegs's stomach and his upper arms on Fishlegs's chest as he says, "Fishlegs…I want you to fuck me."

Fishlegs smiles. "I was hoping you'd ask." Dagur pushes up and rubs Fishlegs's leaking cock tip around his pucker, lubing it up for the impending ride before squatting down and pushing the thick cock tip into Dagur's waiting Machamp ass.

Dagur groans deeply once the cock was inside. "Machhhhhhhhamp!" He says as he sits further and further down on Fishlegs's blue cock, letting the cock spread open his insides and spread his anus wide open.

Fishlegs groans out deep and develops a dopey look of pleasure as Dagur sits further down on him, the tightness of Dagur's ass around his thick Snorlax cock felt even better as Dagur sat further down. If he didn't feel so sleepy at the same time, then Fishlegs might have helped Dagur out by reaching up to stroke his dual cocks.

Reaching down, Dagur used his original lower arms to begin stroking his grey cocks as the pleasure of Fishlegs spearing his ass was just that good and uses his upper arms to grip Fishlegs's shoulders and ride his cock like he would ride his dragon.

Fishlegs mindlessly pumps his hips up to help out Dagur, helping Dagur get balls deep onto his cock and making him groan even deeper. As soon as Dagur felt the entirety of Fishlegs's cock in his ass, that was enough to send him over the edge as both of his flesh rods spray cum onto Fishlegs's head, belly and even his own torso.

However, Dagur wasn't done yet, as he needed to help Fishlegs fulfill a certain animal instinct, breed. Dagur knew that in that moment, he was Fishlegs's mate and as a proper mate he needed to make sure Fishlegs had achieved full satisfaction by letting him fuck his asspussy until he cums and fills his ass with potent Snorlax egg batter.

Dagur gives Fishlegs a lick on the head before starting to ride his cock even more, keeping his ass clenched around the meat pole while Fishlegs kept his dopey smile on out of pure pleasure. Soon after, Fishlegs humps one last time and unloads a huge load of thick cum that expands Dagur's stomach and makes him look 7 months pregnant.

As soon as Fishlegs was drained, he flops his head down to the ground and falls right to sleep, making Dagur smile at just how cute he looked.

Meanwhile, Hiccup, Astrid and Ruffnut were at the entrance to the stadium where Hiccup was banging on the door. "Open up, you sick perverts! What do you think you're doing, turning us into sex crazed beasts?!"

Ruffnut adds while rubbing her head, "Hey Hiccup…I'm starting to feel a bit light headed."

Astrid adds, "Yeah, me too."

Hiccup looks to Astrid and Ruffnut and replies, "It's probably the gas getting to your head." He bangs on the door some more. "Who are you and what are you doing to us?"

However, it was then that Hiccup noticed it was too late as his hands also began to turn into 3 digit hands with thin fingers and started to turn green. "Oh no! No, no, no!"

What Hiccup didn't see was that his hair had retreated into his head while the top of his head sprouted two pointed horns, his whole body became covered in green scales, his eyes became covered in some kind of clear red shield, his back sprouted diamond shaped wings with red outlines, his butt grew a tail with patches of dark green and three diamond shaped fins at the end, his arms became much shorter compared to the rest of his body, his balls seemed to retract into his body and his cock seemed to split into two 9 inch hemipenises.

Once Hiccup, no a Flygon, looks down as the green lizard form he had taken on, he asks, "What am I?"

It was then that he heard some groaning next to him. "Hiccup…" He looks over and, through the red stained shield around his eyes, he saw two creatures lying on the ground.

On the left was an orange weasel-like creature with a yellow flotation device that wrapped around her head and extends around her arms and then again around her back, twin tails, blue fins extending from her arms, engorged orange breasts and a puffed up, yellow ringed vagina to top it all off.

On the right was a black lizard with a very long tail, a purple lining with red stripes on the torso, two ribbons that extended from her back, breasts that were easily the size of her head and a vagina that could swallow her former hand.

The orange weasel, Floatzel, says with Astrid's voice, "Hiccup…we are in need...of cock!" Her vagina was leaking fluids onto the floor like a stream of water.

The lizard, Salazzle, adds in Ruffnut's voice, "Come on, Hiccup…help us!" Her vagina was also leaking fluids that seemed to have strong pheromones wafting off of it.

Hiccup stares at the two female Pokémon in front of him, dicks twitching and dripping pre to the sight of their pussies leaking. "Well…I suppose I can't turn down and offer from such lovely ladies."

Hearing this, Astrid rolls onto Ruffnut and pushes her rear down, smushing their pussies together as they wait for Hiccup to come over. Hiccup leans in, extends his Flygon tongue and begins licking up both pussies, getting a wide mix of flavors.

From Astrid's Floatzel pussy, he got some rather watery fluids that had a wonderfully salty taste, whereas from Ruffnut's Salazzle pussy, he got a sweeter, muskier taste and her fluids were a bit thicker, but all the more intoxicating.

Both girls groan from having their pussy licked, but they just couldn't help but feel like they need something else, something…bigger. "Hiccup…we can't stand it…we need your cock!" Astrid says.

Hiccup smirks to that. "Well, since you asked so nicely." He stands up and rubs his rods between the two females, getting them slick with their drizzling cunt juices before pushing them in, making his upper cock go into Astrid's pussy and his lower go into Ruffnut.

The moment Hiccup was inside the girls, he had to pause a moment as it just felt too good. He couldn't believe the sensations he was feeling around his dicks. Ruffnut's lizard insides were very warm, almost hot to the touch, while Astrid's weasel insides were much cooler, it was the ultimate mix of temperatures that almost set Hiccup off then and there.

Hiccup then grips Astrid's hips with his green hands and proceeds to push his cocks in and out of her and Ruffnut, indulging in their insides and making all 3 groan very loud.

Both Astrid and Ruffnut had kept their eyes closed and their mouths hanging open as Hiccup worked his magic on their cunts, Astrid mindlessly leaking fluid from her mouth that drizzled down onto Ruffnut's face. Feeling the fluid on her mouth, Ruffnut opens her eyes and reaches her hand up to shut Astrid's mouth before saying, "I think I have a better place for that drool to go."

In a sudden move, Ruffnut pulls Astrid down and locks her into a kiss, making their muzzled mouths collide with as much love and passion as they could muster. Thrown off a bit by the kiss at first, Astrid smiles and returns the kiss, pulling Ruffnut in as the two of them clash lips and tongues in a very sensual make-out session.

Peeking his eyes open through his red covers, Hiccup sees Astrid and Ruffnut making out, causing his tongue to hang out as he comments, "Holy shit that's hot!" So he grips Astrid's hips some more before pushing his cocks in and out and in and out of the two pussies, mind flooding with the pleasures of the mixed temperatures, the smells, and the overall sensations of fucking the two gals.

In the midst of making out, Astrid reaches down and starts fondling and squeezing Ruffnut's breasts, causing her to release some of her pheromones which went right into Astrid and Hiccup's noses, making Hiccup harder, as if it was possible, and Astrid lose it and cause her juice to spurt watery fluids all over Hiccup's upper cock.

With the cool fluids all over his dick, and with those same fluids dripping down to Ruffnut's pussy and getting her to feel the same cool, watery fluids, Hiccup increases the pace and fucks the girls at a much more rapid pace as he feels his internal balls slosh and churn with potent Flygon seed that was ready to burst out at any moment.

Returning the favor, and continuing to make out with Astrid, Ruffnut reaches up and squeezes Astrid's breasts a bit, causing her to mindlessly inflate the flotation device and wrap it around Ruffnut, squishing her under the weight as Astrid's breasts also release a good amount of watery milk that coated Ruffnut from below.

After a few more thrusts, Hiccup thrusts one last time as his internal balls clench up and his cocks each release a ton of seed that bloated out Astrid and Ruffnut's stomachs, and causing the girls's cunts to release some of their own fluids that coated Hiccup's cocks.

Once drained, Hiccup pulls out and collapses down onto the floor on his back, letting his cocks eject a bit more cum as they begin to soften. Astrid and Ruffnut move their way over to Hiccup's sides with Astrid on the left and Ruffnut on the right, both of them held Hiccup in their embrace as the three of them relax and recover from that very passionate mating session.

Soon after, the purple smoke of the gas cleared and the people in the viewer's box look down at the Charizard, Blaziken, Snorlax, Machamp, Flygon, Floatzel and Salazzle that all were lying around the stadium floor, cuddled up in each other's embrace and all leaking fluids from just about everywhere.

The white haired man comments, "…Exactly as expected. Get the toxin back to the base so we can start producing more of it."

One of the workers then asks, "What about them, sir?" he gestures to the Dragon Riders turned Pokémon.

The man waves his hand. "Oh, send them and their dragons off to a remote island. That was but a small dose of the toxin so it will wear off in an hour, plus they won't remember a thing once they wake up." With that, the man walks off.

Thank you for reading this story, I do hope you enjoyed it.

Also, because I know you're gonna say it, yes it would've been easy to just turn all of them into dragon Pokémon but I wanted to challenge myself a bit and figure out what sort of Mons would fit their personalities better. You might have your own thoughts about it, and that's ok, this is just what I decided to do.

Anyway, take care and I'll see you next time!
