A specific Charizard was seen flying away from the valley of Charizard. This wasn't just a morning stretch or anything: this fire being was on a quest: a quest to find some old friends.
It was a long way but the Charizard made it into a town. He flew over what seemed to be a very large farm. Charizard spotted someone in the forest: it was just who he was looking for. He started to land...
The person... or Pokemon in question, was a Scyther. It was slicing up a tree with its razor sharp forearms. It suddenly stopped when it heard something approaching him. It turned quickly and saw... the Charizard landing. it blinked... and smirked.
As Charizard landed, he looked at Scyther and smiled as well.
Scyther rubbed its claws together as if to signal for a fight.
Charizard shook his head and approached Scyther, who remained still. Once the taller fire type got closer, Scyther unfolded its arms. The two were very close at this point... Charizard grabbed Scyther by the shoulders... and leaned in to kiss the Scyther on the lips.
Scyther closed its eyes as it titled its head once Charizard's lips touched its lips. Its sharp arms carefully rubbed the sides of the fire type during the lip lock. In no time at all, the Scyther became very aroused; proof was its... his penis growing from his hiding place. He grunted and pulled from the kiss to look down at his pink and erect penis.
Charizard followed the bug type's gaze and smiled. He then backed up, turned around and got on the grassy ground before he lifted his heavy tail up. He then looked behind him and gave the Scyther a pair of bedroom eyes.
Scyther smirked and gladly took that offer from the power bottom fire type. He came up and hugged that thick tail carefully before shoving seven inches of cock inside that very warm tail hole. The type disadvantage was strong but Scyther was stronger and went through with it.
Charizard folded his arms and had a look of pure bliss on his face: blushing cheeks, tongue rolled out to the side and smoke coming from his nostrils from how much he was huffing from it all. His large nine inch dick grew from its slit and rubbed the soft grass underneath, causing him to groan more as he tried to hump the ground to feel more of that wonderful feel.
Soon, other Pokemon on the farm were coming to that spot after hearing some weird sounds. To name a few, a Bayleef and a Bulbasaur walked up... and froze as they saw the sex happening. Both of them felt awkward for staring but their bodies didn't allow them to move as it was a rather fun thing to see an old friend again with another friend.
Charizard and Scyther saw that they were forming a crowd around them... so they increased their actions. Charizard dug his claws into the ground as he pushed his butt back on Scyther, who leaned more onto the big fire type to really start drilling into him. Charizard wrapped his moved his tail to the side so the flame on the tip wouldn't distract the other male into plowing his big ass.
The watching Pokemon were either squirming in their seat or closing their legs together to hide their arousal from the others.
Scyther then pushed in deep and let out a loud cry as he started to cum. Thick bullets of his seed shot right up Charizard's ass. Charizard's hands formed into fists as he felt that wonderful and warm seed splashing over his prostate... over and over and over... then it was his turn to cum. His meaty dick twitched rapidly as his pearly white cum splashed over the grass it nested in.
The air was filled with the scents of sex as well as the soft pants from both Charizard and Scyther... and even the other Pokemon that watched were panting. Either from masturbating to the action or from being so horny from the show.
The moment ended with Charizard and Scyther looking at each other... grinning and chuckling as they each walked off to leave the scene to grab some berries to recover from their little exercise. 

-Later-

Charizard was once again on the move and this time his destination was a volcano.
He landed on the lip of the volcano and peered down at the bubbling lava below. His nostrils flared as he inhaled deeply... then he exhaled heavily, shooting a flamethrower out of his mouth and down to the lava.
Suddenly a pillar of lava shot up from the spot Charizard shot at. From the pillar, a form jumped out and landed on one of the multiple rock pillars that were in the volcano. It was a Magmar. He saw Charizard... and smirked as he got into a battle stance.
Charizard smiled and shook his head softly. He then licked his lips and turned around to get on his knees and lifted his thick tail to present himself to the other fire type.
Magmar blinked... and tilted his head. He thought this was a trick...
Charizard flexed his asshole to Magmar and nodded his head for him to come over.
Magmar jumped from pillar to pillar until he was on the lip of the volcano with Charizard. That large rump looked mighty tempting... he was already stiff and ready to battle Charizard in another way... a steamy way.
Charizard growled softly and swayed his wide rump left and right.
Magmar couldn't hold back anymore; his lustful urges were starting to take over. He got into position and slowly started to shove his nine incher inside of Charizard's butt,
Charizard closed his eyes and huffed out some steam from his nostrils as he was being penetrated. He kept himself still for his fiery friend. He even tightened himself to give his friend more of a good time.
Magmar groaned out and squeezed at Charizard's body some more as he only increased his speed in response to the tightening. The area around them were getting hotter. Any pre that would drip out from either male would land on the rocky edge of the volcano and right away, it'd sizzle into small steamy clouds of musk.
Charizard's ten inch dick was throbbing so much; thanks to that, the tip of his cock kept bouncing on the hot rocky ground. It was a slight tickle and teased the big dragon more. He started to groan out more as his orgasm started to creep up on him.
Magmar's speed increased. Thin smoke started to come out of his nozzle mouth. His fat  flame colored nuts swung repeatedly as he really dug that needy cock inside of his friend's ass... it wasn't long until...
Charizard and Magmar both tilted their heads back and shot a flamethrower into the air as they moaned out together. Thick spurts of fire type cum sprayed out onto the rocky ledge as well as inside of Charizard. The creamy goo was heard sizzling upon landing, making the area around them even more cloudy and musky. 
Their nostrils were filled with the heavy stink of musk; each with a dopey face as if they were drunk. Magmar shook his head to knock himself out of that small trance. He pulled out of Charizard and sighed once his spent cock was free. He looked down to see the dragon's butt hole gaped and drooling of his seed. It slowly regained its shape as Charizard wanted to try to keep in as much of that gift as possible. Magmar smirked and looked up at Charizard's face...
Charizard was looking back and smiled back at the other fire type. He made a series of soft growls and grumbles, showing how much he enjoyed their time together. 
Magmar went up and hugged Charizard, nuzzling with him and showing him that he was welcomed to visit anytime. Either for more fucking or sparring.
