The slow afternoon sun slowly crept down over the horizon heading for the other side of the planet with the night life coming alive all around them allowing for the actual thought of stopping for the night crossed both Ash, Pikachu & Misty's minds knowing how dangerous the forest can be during the night. Especially with neither one of them was having a Pokémon that could really stand a chance against a bug or forest type Pokémon except for Pikachu's electric attacks on bird type creatures. Moreover with no chance with getting out of the forest before the night had fallen with chances of getting lost until morning.
Dropping their bags to the ground in a clearing that overlooked the forest below offering a good chance for the two to continue on when the morning came, Ash pretty much dropped to the ground looking beat although Misty highly doubted that sinced the track through the brush barely caused either a sweat. However it was the climb that took them to the vantage point was some of the harsh trek up there.
"Boy is I beat!" Ash complained plopping down on the ground where Pikachu joined him. The two having just started getting along, which was getting to a point that both seem to act like each other Misty swore under her breath as she tossed her bag at him causing him to get plowed in the face. "Hey! What was that for?!"
"Ash, you aren't getting away from work that easy! Go get some campfire wood & I will get a meal prepared." Misty said angrily as she reached into her larger backpack digging around for packages of meal.
Grumbling under his breath before picking up him off the ground brushing him off. "Come on, Pikachu. Let's go get the wood before the slave driver throws something else at us."
"What?! How dare you call me a slave driver, you lazy bum!" Misty glared angrily at him causing both of them to retreat into the woods rather quickly to avoid from getting hit again as Misty hefted something bigger ready to throw it at Ash. Letting out a low growl before continuing on with the prep work, Misty seemed to concentrate on her work wanting to try & avoid from being too mad at Ash. An immature kid from pallet town, she had met him he had been being chased by Spearows that seemed mad for some reason.
Then he took her bike being followed by the pack of mad birds which caused her to join in on Ash's journey to become a Pokémon master, demanding to have him pay for a new bike for her. She also came to realize that with the way that he went about spending what little money either he or she had, that Misty would never get a new bike in her lifetime.
~My lord I am going to be stuck with this kid for sometime. ~ Misty grumbling finally finding what she needed before she went to work prepping food. Pikachu was the first to reappear with a small stack of twigs having to work with its small size, it couldn't carry too much. One of the few people in the group that she actually can have a enjoyment of companionship with who seems a lot more mature than his trainer.
"Thank you, Pikachu. At least you are responsible." Misty answered offering a friendly smile.
"Pi-Pikachu!" the little mouse answered offering a cheerful smile before charging back into the woods leaving her back to her work as she used the wood that had been brought to her to begin a small fire figuring that once Ash got back, if he hadn't fallen asleep or gotten lost in the forest.
The sun finally set with the sound with Ash finally returning just as the night sky returned allowing the night to take over leaving only a fire light to illuminate the camp. Looking up as Ash collapse on the ground dropping the sticks that he had been carrying up the hill...two bloody sticks!
"Is that all you could find in the whole forest?" she gasped in surprise looking angrier than concern at that point.
"All of the trees were covered with weedles & kakuna! I was lucky enough not to run into a beedrill!" Ash replied looking shock & hurt as he had tried his best truly finding that the trees had been littered with bugs. Misty herself hated bugs herself to the point that she tried to avoid any whenever they found or saw one.
Rolling her eyes as she took the few sticks that were offered throwing them into the blaze after breaking them in half began stirring the pot sitting over the fire. Either tired or busy, all of their eyes were turned away from the horizon when a dancing little form floated throughout the air skimming along the tree tops stopping long enough to notice the campfire cocking its head to the side seemingly to study the camp. After a long second, the Pokémon continued its journey quickly heading toward the camp.
"Is the food ready yet?" Ash grumbled hearing his stomach grumbling hungrily.
"Why don't you get up & stop whining like a little child & give me an h& with the food." Misty answered picking up her bedroll throwing it at Ash with a bit more oomph, instead of allowing him a chance to defend him. Suddenly a thick but cushiony bubble appeared in front of the bag having it bounce back at her giving Misty barely a second before the bag hit her in the chest sending her back to the ground in surprise of what just happened to her.
"What the heck was that?" she gasped when a small feline like creature appeared in front of the three offering a mew as a possible greeting but neither knew. Covered in a layer of fine pink hair that was barely visible to their eyes with large feet & big blue eyes two small pointed ears sitting on top of its head with a swirly tail swished behind its back.
"A Pokémon!" Ash cried in glee from the prospect of seeing a new Pokémon just a couple of days out of pallet town, reached for his pokedex hoping to get a scan in before the creature disappeared. However he found that his has began to cramp up causing him to drop the little device allowing it to clatter to the ground.
"Mew?" the creature asked turning its attention to Ash as the creature seemed to be a playful kitten wanting to play although both found it would be easier if either Pikachu or the strange Pokémon could speak human language.
Before any of them could react, Ash cried out in pain becoming doubled over in pain that ranged into his stomach arching up through his has causing him to lose his breath. Forcing his has out in front of him trying to send the ache out of his body stopping when he noticed a horrifying feature in the light of the camp fire.
From the light, he watched in horror & shock as his fingernails turned black before his finger began to fuse together going out of focus before refocusing again revealing a set of perfect cloven hooves that pawed at the ground. Grunting finding a familiar pain following into his feet forcing him to all fours where the cramps continued to force his body to become straight standing up on the new feet; all four of them to his shock not being able to stand on two it was his only option.
As soon as his body reached a full stance in which he was standing on the four hooves causing him to look down at himself as the hooves were able to support him growing muscles allowing him to feel more comfortable & balanced on them. After a while Ash found that his muscle weren't cramping any more allowing him to almost relax however that didn't seem to last long.
Further up his thighs & arms, the muscles began to spasm causing his new legs to shudder as the sound of clothing stretching & ripping brought the reality those new muscles underneath his skin pushing the skin outward causing the new muscles to break through the clothing to form properly & completely. Within a matter of seconds, Ash stood there in a new form almost a new form completely nude to the cold air causing him to start to shiver.
The creature seemed to realize this so it continued the change causing a light yellowish fur to spread across his skin allowing his shivering to stop & relax once more. Gasping out in shock & sudden pain as his ass started to swell bigger sending him almost off balance with the bulging new muscles in his back continued upward following his spine making the muscles that he already grew to larger portions.
The sounds of crack & crunch as his back became hunched allowing his skeletal to grow stronger allowing that none of his new organs to be crushed, Clenching his eyes in pain, he found that his mouth couldn't form the words as his neck started to stretch out of portions allowing it to become thicker & muscular.
Jerking his eyes open as his head reshape pushing his eyes on either side of the skull as his nose pushed outward allowing a neigh & whine to let loose from his lips. Breathing hard feeling little or more changes occur across his body either adding new features to his new form which included a horn that broke through his skull. The night life sounded out all around him as his ears twitched trying to find the source of each one find that they felt like they moved in each direction where the sound came from feeling them become loose & able to flap almost when not perk up.
Ash breathed heavily feeling him bursting with energy which was soon joined by an intense feeling of flame & heat sending it chorusing throughout his body. Letting out a long hard whine throughout the night allowing for the final changes to erupt throughout his skin sending several continuous jets of flames shooting throughout his body.
Like a fart almost a steady thick flame shot out of the end of his spine & stood continuously in an angry bushfire almost that flickered into the air. One single ember seemed to touch his fur causing another jet of flame to erupt along the middle part of his body to catch on fire igniting his mane once again a continuous flame. Further down on all four of his legs, flames were following the manes example catching on fire. From all of this exertion that chorused through his body caused him to nearly collapse from exhaustion from the sudden changes.
After several minutes of relaxed breathing, Ash finally felt his blood pressure lower & heart settle back to normal, although he wasn't sure what was normal. All around him the night sound & smell crashed in on him from all sides causing his new senses to become overwhelmed causing him to shake his head. One of these new scents caused his nose to flare making him to shift his gaze downward where he found Misty experiencing a far harsher changes although it was apparent that she was changing into something similar to his form.
Misty gasped & cried out as her clothing shredded from her body leaving her breasts, erect & aroused to stand up in the night cool air. Her opening flared allowing an erotic smell to illuminate the air as her eyes locked on the small creature feeling her back crack & stretch causing her to cringe from the pain. She was finally able to get her mouth to work.
"Pleasseeee...stop...this...I-" she tried to speak however she found it was becoming more difficult with each passing minute as the changes continued to rack her body with pain & a deep seeded need to be pleasure caused her agony. The small creature cocked its head at her curious about her words before turning its head toward the perfectly form horse in which Misty was to come coming to rest on the steeds back giving Ash a nibble on his back causing him to whine & rear causing the small creature to become spook. With a blink of the eye, it had disappeared leaving the transformations to continue on the poor former human.
Ash settled down on all fours once more, he found himself sniffing at the ground stepping closer to the human finding that his erection was starting to push forward out of his sheath with each step he took. Misty unaware of the approaching form behind, tried to force herself up on to the scrambling to get up on to her new hooves, She found it was a lot more difficult with her hooves unable to get traction causing her rear to jerk up into the air allowing her pheromones to release more easy just within an inch of Ash's sensitive nose causing him to jerk back from the shift.
Leaning down breathing in deeply of her scent, Ash found his nostrils flare & his excitement growing as he allowed his tongue to slip out of his mouth as he allowed the tongue to trace up along the outer puffy lips of her sex causing Misty to gasp in shock. Turning her head to the side, she found the creature that had once been Ash with his nose in her growing rump eagerly licking away greedily.
"Ash...stops...oh gods..." Misty pleaded with the creature finding that her hips were responding on their own pushing back into the licks finding her arousal growing by the minute. Her budding breasts seemed to be growing themselves with the nipples stretching out into a thick membrane & covered with a thick layer of skin with fur growing up around the nipples before both began moving down to her crotch as her chest began billowing outward swallowing up what was left of her breasts.
Ash found that the licking & nibbling at the leaking sex he was giving was frustrating causing him to draw his head away from Misty's growing rump & seductive sex that continued to draw his attention, leaving it only a second before mounting her rump wrapping his forelegs around her.
In no time at all, he was thrusting his thick pole in a desperate search for Misty's extremely wet opening that seemed to be giving off signals for wanting the pole desperately against Misty's wishes. Upon feeling the sharp thrusts that were centered around her rump, Misty lusty mind that had been fogged over cleared enough to realize what was about to happen. Opening her mouth once more to try & to stop Ash from continuing she found however instead of normal words coming out, there came a neigh & whine. This left her little choice but to frantically try to get herself out from underneath Ash before he found her pussy.
However she had taken too long trying to reason with Ash; who at that very moment cock had found her swollen opening taking little chance of losing the find, he slammed his enlarged member home past the virgin folds & barrier that indicated that she was or had been a virgin before that night. Misty's shrill scream filled throughout the night as Ash's human mind seem to have lost all rational thought & reason, & had allowed the animal inside to take over driving his cock deeper & violently into Misty's opening.
Each thrust seemed to speed up the change in her as she found her body slowly starts to become accustom to the huge member that was stretching her pussy beyond its limits as it seemed to take savage ownership of her body ripping away her virginity in one shove. The thrusts never let up with its lust in the movements & little care for anything especially Misty below him as Ash continued to neigh loudly driving in the last food or so of his cock into the half-way transformed companion. Whose body slowly accepted the large phallus although not entirely willing?
Ash could feel Misty's inner muscles squeeze down on his cock, spamming ever few seconds along every inch of the member. There came a point where she found herself pushing back into the thrusts wanting more of the phallus with the desires going on. On her end, Misty couldn't believe on how her body was enjoying this when it was so disgusting to her mind that she found a second mind in there that she didn't recognize. Although she was finding this shocking she found the other side of her was starting to emerge by each enjoyable thrust into her body, letting out a squeal & neigh of joy & lust from getting what her loins demanded.
Crying out suddenly, she felt her pussy walls spasm & convulse on the massive organ signaling a massive orgasm that trigger multiple times before she came to realize that her own transformation had finished during the time with the fires burning brightly flaring each time her body convulsed in pleasure with her first one causing a fire to envelope the two into one flame. Letting out a large shrill of his own jamming his cock as deep as it would go; Ash unleashed a torment of seed into Misty's fertile body below him.
Gasping & grunting panting in the process, Ash found he slumping over Misty's stern form as both breathed heavily from the pairing with her being able to support his weight easily while he was able to slip out of her well used opening. She just stood there coming down from her own neigh trying to relish the feeling of such a savage mating after sometime during the process, she found it hard to believe she wanted more from the Stud.
~Did I just call him that?~ she asked herself stunned by the thought figuring that it must've come from her other self. That was clarified when she found herself pressing her rump back into the cock that had been slipping out of her opening grabbing ahold of the cock once more holding it firmly in place. At that time Ash found that his erection perked back up instantly from the push.
After the initial mating that he had given to Misty & enjoyed it, Ash found his mind clearing allowing him to realize what he had done causing him to want to pull out as soon as possible however he found the process more difficult than thought.
For one reason when his cock moved about an inch out of the warm walls seemed to clutch down on his member & began massaging it in the process. Second was the fact that Misty was pushing back against his erection pulsating the walls even further each time. This caused him to realize that she was okay with going another time causing him to reverse the withdrawal.
The sounds & early morning breeze that shot throughout the camp sending a child to run throughout Misty's naked body causing her to shiver stirring from her slumber. Breaking from the clouds, the sun shined down on her face causing her to squint her eyes before slowly opening them. "What happened?"
All of the events that happened last night were all fuzzy as she rolled over coming face to face with Ash when she reeled squealing in fright pulling away from him. Furthermore when she brushed her hand across her breasts, she found that she was completely naked, what was worse was the fact that Ash was also. Grabbing the pot, she turned back to Ash who started to wake up muttering a "Huh?" before the frying pan hit him straight in the face sending him backward.
"Hey what was that for?" he asked surprised coming fully awake looking even more surprise to find Misty completely nude. "HEY! PUT SOME CLOTHES ON!" He said before looking down barely to find the same thing grabbing for his backpack to cover himself. "What in the world happened last night?"
"How should I know? All I know is that I woke up this morning laying naked next to you so you tell me." She accused him poking him in the chest. Suddenly Pikachu came forward in a rush with Ash's pokedex held in his mouth flipped over as he punched in a key revealing scanned data. Revealing a rapidash before them.
Quickly Pikachu went about drawing a picture indicating about how those two had transformed into the creature during the night. However he left out about the incredible sex that they went about having.
"We transformed into that?" Ash asked in surprise.
"If that happened why did we change back and if so, can we change back? Our trip to Pewter City and any other city by days."
Looking at each other, they went about trying to transform on their own finding it much easier to do than thought before gathering up their gear, with Ash being the pack mule dashed off down a separate path for Pewter City.
