As the sun rose over the treetops, a 10 year old fox cub named Sullivan, set off on the start of his Pokemon journey. Like other kids his age, he was incredibly hyped for this adventure, however, unlike other kids, he hadn't been given a starter companion by any Professor. As his family lived far up in the hills away from civilsation, his first task would be to walk down the long mountain until he reached the town the Professor lived in. His parents shouldn't have been so careless, but after all, they weren't trainers themselves, and didn't know what dangers their boy could get into... Having walked for a few hours now, Sully was starting to get tired. He was only a mile or so away now, but he'd still need to rest for a quick spell. Going of the road to the side, he found a large tree to rest under. As the shadow settled over him and the gentle wind breezed across his body, he took a deep sigh and began pondering what Pokemon he should choose when he got to town. After a few minutes had passed, he was suddenly snapped out of his day dream as he felt a huge thump quake the ground beneath him, followed by a defening roar! He quickly covered his ears and curled his knees up to his body. When the roar faded, he glanced up and gasped in fear at the huge Charizard that was standing right in front of him! Too frightened to move, all he could do was stare at the beast as it leaned It's neck down and growled at him. Sully was completely frozen in fear, and was barely able to stutter, much less breath regularly. Before he knew it, the Charizard snapped him up in his jaws by his sweater and leaned back up. As he hanged from his mouth, Sully began crying, as well as making a mess of his undies. At first it was blank, then after a few seconds the tip in his shorts started getting darker, and then a streak of clear urine could be seen leaking out and down his leg. The Charizard sniffed the air, easily detecting the scent of urine that the young cub was letting loose. Gripping him at his sides with his paws, he lifted the boy up in the air and held him in front of him, taking a huge whiff of that wet crotch. This just caused Sully to yelp out like a girl, as he thougt it was incredibly emberassing. The Charizard however let out what could sound like a chuckle, as he pinned one of his teeth in the side of the shorts and began pulling at them. "Wuaah, s-stop that! Aiigh!" Sully managed to let out before the shorts slipped off his spindly legs and ended up on the grass beneath him. The Charizard look on with a viscous smile as he saw the boys tiny member leaking out even more urine into his tight, cute undies. Poor Sully was still crying as he attempted to flail his legs a bit at the Pokemon, but to no avail. Letting his large tongue drop out of his mouth, Charizard took a long, slow and good lick at the wet crotch. This instantly caused a rush of mixed feelings to hit Sully. Like a tidal wave they washed over his body, confusing him even more as to what he was supposed to be feeling right now! That lick felt somewhat good, but he was still terrified of the Pokemon itself. "Haaii! Wh-what are you..d-doing?" He muttered out, though he got nothing but a low growl back. Using his teeth again, Charizard pulled down the wet undies as well, leaving the cub naked from the waist and down. Having never been naked like this before anyone before, Sully blushed up something fierce, and without even realising it, causing his tiny member to grow hard in a mere 3 seconds! "Wh-what's happening? Why does this f-feel so good...p-please just let me go!" He got no response however, only another slow lick to his now firm 4 inches tool. Being his first time to ever feel anything like this, poor Sully yelped out in his girlish voice again as a few droplets of clear cum spurted out from his member and right onto the dragons face! "Iiiaaahg!" His whole body trembled in pleasure, before relaxing, letting him catch his breath. Charizard chuckled again and licked a bit of the cum off his snout, appereantly enjoying the sweet taste. It was however, his turn to have some fun. He flipped Sully around in his grip, laying his back up against his chest. Without even having seen it, the timid boy was now greeted by a 14 inch long and 4 inches wide monster of a cock up against his virgin tailhole. "Wh-what is that!? Is that your...Oh god, It's huge! T-take it away, It's p-poking me!" He cried out as he felt the wet tip lightly tap against his bubbly butt. Draggin his tongue up against his furred neck, the Charizard just tried to tease the boy as best he could before he got serious. He stretched one of his claws out from the side and gently nudged at Sully's nipples, 'causing another shiver of unexpected pleasure to rush trough him. "Ayya, stop that!" He yelped out, but to no avail. Grabbing a hold of his legs, Charizard bent them upwards and laid them up against Sully's sides. This just caused him to blush even more, and his tiny dick to get quickly erect again. Before he even had a chance to whine again for the dragon to stop, he felt something wet squirt against his buttcheecks, followed by the broad tip of a penis trying to stretch his lovehole enough so it could get inside him. "Aaaugh, that hurtmmfh!" Sully was promtply shut up as the Charizard gave him one of his big dull claws to suck on. He could do nothing now but close his eyes and hope it would soon be over. After a few more seconds of feeling his hole getting more and more stretched, Sully's eyes went wide open and he let out a muffled scream as the head of the pokemons giant cock slipped inside his butt! Sully glanced down as tears dripped out of his eyes again, seeing a big bulge forming just above his waist line. Immideatly he gave out more muffled screams in a fit of panic, but was shut up again as he felt the claw sinking deeper into his petite mouth. The Charizard on the other hand, was in heaven right now. Never had he felt such a tight butt around his cock. The inner walls were clenching so hard down against him, he was almost about to cum then and there. But he held it back as best he could, as he wanted to gett balls deep before he released anything. Using his other paw to push the boy further down his length, he enjoyed hearing the muffled shouts that kept coming out of the poor thing. Charizard even felt a little sorry for him himself, but that wasn't gonna stop him from breeding his lovely butt with gallons of cum. After pulling him up and down about halfways down his dick, and sully watching in agony as the dragons cock bulged out in his belly, only to dissapear again, the Charizard slammed him all the way down on his shaft! With nearly the whole cock inside his lithe body, Sully grabbed the hulge bulge that was sticking out in his stretched belly, in and attempt to push it back. It was of no use though, and after another loud roar was heard, Sully watched on as globs and spurts of cum began filling him up! His skin stretched out with each spurt, and he could feel it ending up in the bottom of his belly before it began working It's way upwards, as there just came more and more. The Charizard was smart to plug his mouth with a claw, for after his belly was filled up to the point where he looked pregnant, he felt it gurgling in his throat. As it found no escape however, it went back down and spurted out what it could trough his lovehole, 'causing a mess in the dragons crotch. His own tiny member also let out a few tiny spurts of cum! After a whole minute of steadfast cumshots, the orgasm finally died out. Even if it took some time, the large cock eventually went soft, and with a loud plop it slipped out of Sully's now deflowered bubblebutt. Charizard gave another low growl before he nuzzled his cheeck up against the bloated cub's cheeck. "Uurgh...I'm..s-so full..." He let out as he put a paw on his belly, feeling all the white cum sloshing about inside him, and hearing his belly gurgle loudly. The Charizard took him in his arms and gently plugged up his butt with one of claws to stop the cum from leaking out. With a mighty flap of his wings, he took off into the air, leaving the soaked legwear behind. This kid wasn't going to need that where they were going...
