The Rock Cookie - Tyranitar TF
As David looked upon the entrance to the Pokémon League, he could not help but feel a bit nervous. For several months he had gone through the many towns and cities in Johto, training and capturing many different Pokémon to aid him in his journey, battling and defeating each of the gym leaders and earning all eight badges that he needed to take part in the Pokémon League.
Now he had gotten here though, he was worried that he hadn't done enough training and preparation for it - the contest was a few days away, but he was still worried nonetheless. Thankfully for the trainer, Mt. Silver was located just west of the League, and was considered by many to be an ideal final training ground before the main event.
As he wandered through the grassy pathway that was Route 28, he could see various different Pokémon lying in wait - Ponyta, Dodrio, Arbok...all of them were high level, and would no doubt give him a bit of practise before he made his way into the mountain - thankfully there was a Pokémon Centre just near him, so he was able to get his team healed up after a few battles.
He spent the good part of around three hours training his team just outside of the centre, getting them up a few levels, but he knew that it might not be enough just yet to take on his rival trainers and, if he was lucky enough, the Elite Four. He knew that soon enough he'd have to head into the mountain itself and take on its tough inhabitants in order to really pump up his mon.
"Sheesh, watching these guys training is making me hungry." David chuckled a little as one of his Pokémon put the finishing touches on a wild Donphan, knocking it out. "Maybe I should set down and have some lunch, feed my Pokémon as well...first things first though." He recalled his active mon and went back into the Pokémon Centre for what must have been the fifteenth time so far, getting them healed up once more. "After we're well fed, we'll take on Mt. Silver!"
He used a Max Repel as he left the Centre, going through the grass as he went to found a nice place between the Centre and the opening to the mountain so he could eat. It didn't take him too long to find a place, sitting in the shade of the trees just adjacent to the mouth of the cave. He put his backpack down and started to get everything prepared, his lunch and the food for all his Pokémon. As he was setting up though, he felt something gently roll against his hand.
"Huh?" He turned his head around, and saw what looked like a stray Item Ball resting against his right hand. Curiously he picked it up and opened it to look at the contents. Inside of the capsule, he saw what looked like a Lava Cookie, an item that was normally used to heal a Pokémon if it was affected by a condition like Poison or Paralysis. Oddly though the color of it seemed a little darker, almost grey in coloration as opposed to the normal reddish-brown.
"Interesting..." He thought, looking over it for a brief few moments. He had given Lava Cookies to his Pokémon before, but he had never himself tried one out. "Couldn't hurt to give this one a try." He smirked as he took a bite out of it. The cookie had a weird, gravel-like texture to it as he took a bite out of it, feeling very rough. Aside from that though, it tasted pretty delicious. It didn't take him too long to finish it all off.
"Well that wasn't too bad, but I think I should get back to getting lunch sorted....ugh..." He groaned when he felt a sudden warmth flowing through him, his stomach gurgling a little bit. "Maybe...maybe I shouldn't have eaten that thing." He told himself as he grasped his chest. His eyes widened a little bit when he felt it slowly swelling out under his touch, inflating a little hit as his shirt grew tighter, being rolled up past his gut slightly.
"What the hell's going on?" He asked himself as his upper body now began to swell out slightly as well as his ribcage cracked and expanded, barreling outwards as his shirt grew ever tighter. He was starting to freak out a little bit when that warmth suddenly returned, feeling oddly pleasent. "Mm...mmm..." He moaned softly as he felt his muscles suddenly tense up and grow, his abs and pectorals slowly expanding and enlarging, giving him a sculpted six-pack. As his muscles formed, he saw thick plated blue scales spreading over his front in a slight rhombus pattern, thicker olive-green scales growing over his sides and around the blue ones, overlapping them slightly.
"This...this is strange...but why does it...feel so good..." He groaned again as he grasped as his now too tight shirt, ripping it off to reveal his muscled, scale-covered chest. He looked on at it proudly as he felt himself starting to grow a little, his spine starting to slowly stretch and extend.
"Uuhghg....Tttyyyy..." He growled as he felt his arms start to grow a little longer now, the scales growing over his arms as they too bulked up, filling him with raw power as his hands twitched and throbbed, stretching slowly as the palms thickened outwards, vicious claws growing out from his fingertips.
"Yesss....Raannn..." He panted, feeling the bestial strength running through him as he felt his trousers starting to strain tighter against him, his thighs gaining heavy muscle as a bump formed in the back of his jeans, another one forming up the front as the blood rushed downwards, his cock quickly growing hard.
The scales had worked their way over his legs, twin patches of thick, wedge-like black scales growing around the sides of his knees. The fabric of his jeans burst around the sides, revealing his scaly thighs to him as the rips ran up and down his jeans.His shoes burst open as his feet stretched longer and wider, socks torn apart by his massive feet. He felt a throbbing in them as the toes fused together into three large digits, broad claws growing from his toes.
"Muuhrhahah...Itarrr..." His growling grew louder as he began to stroke himself through the tenting fabric, a few blobs of pre making the front of them grow damp, weakening it further as his cock tore out through it, pulsing with need. The skin had pulled back to around the base of it, forming a thick sheath for it as his maleness grew a good few inches in size and thickness, throbbing proudly in front of him as it reached a foot in size and eight inches in thickness. The head grew into a large, barb-covered point whilst the base of it gained a large, fleshy knot, perfect for keeping his partner in place.
"Mmm...morreee....Tyrrraannn!" He snarled as he wrapped a clawed hand over his inhuman cock, starting to gently pump it up and down before his pace quickened. As he pleasured himself, the bump growing on the base of his spine grew outwards, reducing the seat of his jeans - and the rest of his already tortured legwear - into a pile of tattered scraps.
A long, thick tail grew outwards, wagging eagerly behind him as it grew to what must have been around five feet tall. As it finished growing, he felt the tip of it twitch as the scales at the top peeled back like it was a banana, splitting into four large points, the 'revealed' part covered in segmented scales.
His lustful growls grew ever louder as he kept pumping himself, beating his shaft against his chest as he felt a trio of large spike-like growths emerging from around his shoulders, several more of them growing to fill in the space around his back, a smaller patch of blue scales growing around the middle of his back.
"Rrrrgghhha...Rrraannittarrr...Frrruuck..." He snarled breathlessly, feeling his neck grow larger and broader, becoming as thick as the rest of his now 6"07 form, his head realigning slightly as the spikes grew up past the back of his neck "Nnnrreeddd....Rreeleleassse..." His speech was becoming more and more slurred, mainly due to the pure state of bestial pleasure he was in, slowly being reduced to the cries of the Pokémon he was becoming.
"Ttyyrraannn! Rrrrraannittarrr!!" His voice was lost to the beast as he felt his hair falling around him, the scales covering his face as his jaws cracked and stretched, his nose sinking into his upper jaws as his nostrils flared. He felt his ears shrink away into the sides of his head, leaving small holes as his jaws formed a broad, saurian muzzle, teeth growing into large fangs as his tongue grew thicker to fill his jaws better. He felt his eyes moving to the sides of his head, turning a reddish-brown with slit pupils as they grew narrower, a trio of horns growing from the back of his head and above his eyes as his transformation completed itself.
"Gruurhahh....TYYYRRRRAANNNIIITTTTAAARRRRR!" He roared at the top of his lungs as he came hard, thick seed spraying from his dinosaurian cock, splashing against his chest. His howl continued for the length of his orgasm, soon dying down a minute or two later as he fell back against the ground, panting loudly. "Tyrrraaa....ooohh...that...that was....itarr...goood..." He groaned, grinning wide as he pushed himself back up from the ground, walking over to the nearby fishing pond to look over his new form.
"Oh wow..." He chuckled, smiling wider as he saw himself, now a muscled Tyranitar, the most of his front covered in cum. "Don't I look good." He said, brushing his chest off and washing his hands in the lake. As he did that, he heard something rummaging through his backpack. Quickly turning around, he was greeted with the rear end of a female Tyranitar looking through David's bag for food. She noticed that he was looking at him and grinned, wagging her tail about enticingly.
"Mmrr..well hello there." He chuckled as he approached her, knowing full well what her intentions were. A few moments later they retreated into the cave for a bit of privacy, their roars echoing through the mountain.
As for his entry into the Pokémon League, he managed to storm through it thanks to his new form and physique, the mon he had on his team, and of course, his new mate. Seems like everything worked out pretty well for him, even if it wasn't what he had in mind.
