A commission for a pokemon werewolf story of sorts with a bit of muscle growth. I was truly captured by writing this. Never had I considered that my werewolf stories may appeal to those who enjoy muscle growth, and so I tarried away at making a more detailed transformation scene, outlining powerful new muscle and what not, and yet I did not over-exaggerate it, I kept it minimal and yet effective, or at least so I believe. The anon who commissioned this certainly enjoyed it, and I hope you do to~


From behind the brush a young man stepped out looking flustered while slapping off leaves and stray twigs that speckled his clothing. Two pokemon followed from behind, both with mischievous smiles, a tall Blaziken and a Glaceon, both of which seemed to regard their master with some amusement at his discomfort. For quite sometime they had been lost traveling side by side. Curiosity had led the young trainer and his pokemon into a strange forest in the hopes to find some rare pokemon, but unfortunately it seemed that either the wood was haunted, or they were simply incredibly lost. A mire of fog blanketed the air and hugged around the trees making it difficult to even see beyond the sea of wood and leaves along with a cold that chilled Xin to the bone, no doubt his pokemon were fine with one being a fire type and the other an ice. Although they were lost, they had plenty of food and at the very least they had each other. Xin snorted, hand rubbing through his own black hair. Again he found himself needing to readjust their direction, hoping to at least find a clearing to set up camp. Even though he couldn't see the sun to tell just how late it was, his feet were ready to rebel against the rest of his body, and though his pokemon didn't complain, he cared for them dearly and would rather have them take it easy.

After a bit of wandering here and there through brushes aplenty only to stumble into more trees and even some bramble, he had allowed his Blaziken to take the lead without much hesitation, trusting her sharper eyes more than his own at this point. For a time it seemed that they would be stuck in the thick of it no matter what, but just before Xin was ready to give in, they found themselves in a clearing entirely free of fog and trees. The tall grass reached up just below his knees and for the most part the clearing seemed much more mundane than the rest of the forest, the only thing out of place were a few stones gathered around in a close cluster at the far side of the clearing.

Xin was all too happy to finally have a place to stop and pluck twigs and needles that had stuck to his clothing, that and rest. After clearing a spot of the tall grass for themselves, they set up camp. With Blaziken's help he was able to get a good fire started to keep them warm while they brought up their tent. Of course Glaceon didn't really have a use at the moment so he allowed her to rest upon his shoulders, her tail and body curled around his neck. Once the tent was set up and his pack off of his body he stretched. Even if it wasn't night, he could see that they all needed rest, himself included. Blaziken was leaning against a tree, eyes half shut and head nodding, meanwhile Glaceon was hooked around his shoulders, eyes closed, a soft steady snore sounding off. His own body was a full of little pangs of pain from traveling through such rough terrain and he'd not complain about taking an extended nap. With a small smile he called Blaziken in to join him in the tent just before putting out the fire, they would be plenty warm huddled together inside.

Blankets were put out and Xin made sure the girls had their comfortable corner as soft as he could manage it. Both of them laid down upon the tent's covered floor with very little hesitation or complaint. He stroked the soft blue fur of his glaceon first, admiring the tiny ice-type fox before doing the same for Blaziken. Xin smiled as he felt a swell of pride from looking at both of them, Glaceon was small, but she was a beauty to behold and just as strong. Blaziken on the other hand looked her strength with equal amounts of beauty. Red plumage did little to cover the fire types curved and muscled body. His eyes trailed down to strong thighs, one hand upon Blaziken's leg, the other upon Glaceon's rump, a deep warmth growing through his pants.

Realizing that his hands had lingered too long upon forbidden places he pulled away, cheeks flushed red, eyes tearing away from the sight of his precious pokemon. In truth he had given his pokemon all of his love, and perhaps that wasn't healthy. Xin had desired his pokemon ever since he had received them, admiring the beauty of both the strong Blaziken, and the petite feral Glaceon. Their bodies weren't even the important portion of it, Xin simply held a deep bond with both of them that could not be replaced, and yet he knew it was wrong. A human and a pokemon bearing love for each other more than simple partnership would surely be wrong, and even if they loved him back as he did them and he ignored the forbidden aspect of it, he still could not give them children.

With a sigh he shook his head of such thoughts and moved to his sleeping bag. Typically he slept closer to his pokemon, but with those thoughts still running rampant through his mind he couldn't be sure about his own intentions. Slipping into the sleeping bag he turned his head away from his girls and shut his eyes, hoping that his dreams wouldn't be reflecting what he felt tight against his pants.

Glaceon and Blaziken cracked an eye open once they felt their trainer's touch disappear from their bodies. Glaceon had always argued with her dearest sister that they needed to take the initiative, but Blaziken would rather not put that pressure on their meek master, besides, the fire type would rather see their master act as a proper alpha and act on his own devices and desires. Perhaps one day the trainer would gain the proper courage to fess up to his feelings, or at the very least take advantage of them in their sleep, or something. For now they would have to leave him be. Glaceon seemed most perturbed by this, shifting to face Xin before shutting her eyes again. The ice type had always been much more clingy when compared to the seemingly stoic Blaziken, both of them loved their master dearly, but Glaceon desired always to be by his side, upon his shoulder, or anything that would allow her to be in contact with him, whereas Blaziken could allow him breathing room, though she as well cherished the time they spent during their rest. Putting it out of their minds they both shifted a bit before drifting off to sleep.

Xin could not find sleep. Maybe it had something to do with the perverse thoughts that danced around in his mind and teased him in his dreams, or maybe it was the fact that it felt like there was a rock in his back. The dirt beneath the grass had been speckled with little pebbles and gravel that they just couldn't clear entirely. Wincing he sat up feeling his back pop as he did so. Turning he saw that his girls were happily asleep, good for them. Perhaps their backs were stronger than his and he shouldn't have been whining when his pokemon were roughing it just as much as he was, either way he couldn't sleep. A walk would stretch out his limbs and get his mind off of his odd desires.

Out of the tent he trotted, turning on a flashlight he had gotten from his pack. Even if they were stuck in a verdant forest, something felt so off. Even during the day not a single sound had been made except by the trio of trainer and pokemon. At night the silence was even more chilling, but curiosity gripped him as he turned his light to the cluster of stones. They were at the edge of their little clearing and yet they were gathered in such an unnatural way, they must have been moved. Once he was at the actual boulders they seemed much less impressive up close, noticing that their little cluster had several spaces in between someone could step through. With a small smile he decided why not? All in the spirit of adventure he slid through flashlight trained on the center where he saw yet another stone, but this one was speckled with various gems glowing and shimmering with different colors.

The gems sparkled and glinted in the flashlight's glimmer. Xin's eyes went wide and he thought to run back and wake the girls just to show them the little treasure he had found, and yet, he found himself entirely drawn to the glowing gems upon the jutting geode. He couldn't help but approach the thing, free hand outstretched to feel over one of the gems, a blue thing with multiple facets that seemed to have something foggy within.

Xin tried to get a closer look at what was within the gem, but couldn't see further inside, even with the light so close. He was suddenly then aware of a burning touching the fingers upon the gem, a burning sensation that lanced up his arm and seemed to shake his entire body for just a moment. Xin yelped and brought his hand away, a spark of electric shivers traveling through his arm. When he bent to pick up his flashlight that he had dropped in the shock, the heat that had touched his fingers had begun to grow and fester within his body and upon his skin. Xin paused while bending to pick up the flashlight, fingers then moving to tug at the neck of his shirt instead. It had been chilly just a moment ago and yet he felt so entirely hot now. It was as if the sun were beating down upon him from just a few feet above his head, his brow dotted with beads of sweat.

For a moment it seemed that the worse had passed, and yet he found himself not only just tugging at his shirt's neck, but with newfound strength tearing at the clothing to remove it from his sweating body. It was then that he noticed that beige fur was growing upon his chest, blue upon his arms and legs, black upon his hands and feet. Along with the fur, his body expanded, muscle rippling beneath his new coat, face contorting and changing to have a muzzle as he hunched over, fresh claws digging into the ground. With a new muzzle and tail grown he let out a howl, not of protest but of pure ecstasy! All of his clothes had been torn off by the grand growth in powerful muscle as he transformed into a Lucario.

Kneeling for a moment he blinked, bringing up his new paw and flexing it, gripping and regripping slowly, his entire body trembling from the sudden intense ferocity that sent shivers throughout his new form. Standing a bit shakily he noticed that he had gained a lot of mass, muscle at that, and even beneath the fur he could see his arms, and especially his thighs, had gained plenty of the stuff. Flexing his arm he could feel the bulge and even see it and gripping at his thighs he found that they were rock hard, although they certainly looked chunky enough. He wondered what other new features his new body carried besides an expansion in muscle and well, the Lucario look.

Searching between his legs he saw that he now sported a thick canine's cock, red and jutting out of sheathe, knot and all. His cheeks felt flustered and yet he felt no shame at being so bare, he only felt the desire that he once had for his pokemon, except this time it seemed to have been doubled. To those thoughts his member responded by twitching, the tip dripping with clear pre.

Xin gripped upon his cock at that moment, closing his digits upon it as best as he could as he began to stroke fiercely without meaning to. He couldn't help but think about breeding, breeding his two girls which he had loved so much before as a human and even desired so lustfully. He had been wrong to believe that his desire for his precious pokemon had doubled, no, now as he stroked his cock and thought of rutting both of his mates he knew that his desire had grown tenfold. He needed to be inside of them, to hear them squeal and moan, and as he stroked his cock as powerfully as he could, he growled and groaned out, letting his pleasure be known to the night. Already so close from not being adjusted to his new form he let out a howl, cum spurting out in thick ropes all over the stone that had transformed him, anointing the geode in his thick semen. As he came he felt his entire body lurch forward, muscles tensing, eyes shutting tight as he squeezed tight upon his orgasming member, his cock twitching with every single spurt of cum that flowed free from his massive canine cock.

As he stood there panting he looked down at his still hard and twitching cock in his paws, unsure of what to say, but he knew what he could do, of what he had to do. He would establish his ownership of the girls properly, show them who was the proper alpha among the group and show them his true love. Surely they'd love him now that he was a pokemon just like them, and at this point even if it were forbidden he'd never be able to stop himself. His new form had afforded him some sort of new inborn confidence that he had never experienced before. It was a drive that had him walking at a brisk pace back towards the tent, his eyes not needing the flashlight to guide him back, his nose taking in the powerful scent of grass, and the scent of his two pokemon that he would surely breed. At the same time his new tail swished from side to side excitedly and despite his new size and strength he stepped quietly through the night, on the prowl. Hopefully they wouldn't be too perturbed by their trainer's new form.

Glaceon was the first to notice, her eyes opening wide as her powerful nose caught a scent that made her squirm and mewl. It was the scent of a virile male approaching. Her noises caused the Blaziken to rise from her sleep as well, sitting up with some amount of concern, her arm resting upon her knee, but soon enough she caught the scent too and cooed, eyes half-lidded as she rose further following the scent of the powerful male outside of their tent. Both of them decided to meet this strange male outside, the strange male that had such a strangely familiar scent. When they finally looked upon the large Lucario with wide eyes their noses could not betray them any further. Though the scent was different and much stronger, it was their trainer Xin, his powerful gaze just as loving as it had always been, but this time with powerful lust laced within that wasn't hidden this time.

Rather than wait for the girl's to approach him, Xin stepped forward, one paw at his cock, stroking the thick member so that they could see clearly what he intended to do with them. Xin practically groaned as he saw both of his girl's shudder and shiver, his nose catching their shared desire. No words needed to be said as he approached, instead with the same love and care he had inside the tent as a human, he touched both of them, first the Blaziken and then the Glaceon, both gently upon the cheek. They both pushed themselves to his touch, their eyes half lidded, their mouth's open to let out little breaths that felt warm, even Glaceon's breath felt hot compared to how it usually was. He could tell, could feel that they knew what he was going to do to them, how he was going to do it, and that most importantly they belonged to him.

Neither of his pokemon made a move to feel over his new body, he hadn't given them any indication that they were allowed to move, that they were allowed the honor to worship his body. Such thoughts were foreign to him, and yet they came so naturally with his new body and confidence. Stepping to the camp he motioned at the stack of logs that had once been their campfire. Blaziken responded almost immediately, lighting the fire with her breath. As Xin sat down, the firelight danced upon his body, revealing more of his powerful muscle, more of his new form to the girl's before him. Both of them watched with wide and hungry eyes, but still they waited, shocked that their master was both so brazen and so commanding. They had always obeyed him, but he had never before used his power in such a way, he had never truly been their alpha, he had only been their companion, but now, now they felt compelled to wait for every single little motion he made before making their own movements. As he turned his newly red eyes to them he brought a paw up to beckon them with one digit, both Glaceon and Blaziken moving to fall in next to him, Blaziken on her knees by his side and Glazeon standing at his other side, both of their eyes falling upon the massive cock between them.

Xin let out a breath, confidence bristling his fur as he brought both of his hands upon the back of his pokemon's head. Rather than tell them or make a motion to order them, he pulled their heads forwards against his cock, beak and muzzle touching either side of his cock. Blaziken and Glaceon practically melted from the touch, Blaziken reaching to grip upon his cock with her hands, Glaceon's hungry tongue dragging against her side of their master's new canine cock.

At the same time Xin simply sat there as a king would upon a throne as his servant's serviced him, unmoving on the outside, and yet on the inside a torrent of emotion and primal desire burst forth. He had to be patient, had to hold back, had to let them explore his new body and tease them. For now he would only let them taste, only let them fondle and when his desire and lust built up enough he would pounce upon both of them, mating with both until he was fully satisfied.

Glaceon's cool tongue slid from his shaft all the way down to his balls, her tongue resting there for a moment before she began to drag it across his thick orbs, her mouth suckling upon each ball dutifully. Meanwhile Blaziken had the idea to take her master's cock into her mouth. Gripping upon it firmly she leaned in to open her beak wide, being careful not to harm her master as she swallowed him whole, her eyes shut. That drew a satisfied grunt from Xin as the Blaziken brought almost all of his cock into her maw, her throat bulging just a bit as her tongue touched and caressed the knot of his member. Blaziken shivered then as she bobbed her head back and forth. With this, Xin was unable to stay still any longer. He grabbed Blaziken's head and pulled her so his knot fit snuggly into her mouth as well. Powerful hips moved to push his cock into his Blaziken's mouth, pulling out only to push back inside firmly.

Blaziken's eyes widened for a moment before she settled, her body slumping and shivering as her maw was assaulted with such powerful thrusts from such a large cock. She could hardly believe that her master was a powerful pokemon capable of such rough treatment, it was enough to have her near orgasm just from him pounding her mouth so tirelessly. Meanwhile Glaceon watched the event with wide and lustful eyes. She admired the way her master's new body worked, the way that he took control of the situation, and frankly she wished that it was her mouth being impaled upon that thick cock. Glaceon nearly jumped as Xin touched her head with his free hand, bringing it against his taint just under his balls, commanding her to continue. The ice type shivered and let out a submissive mewl before her tongue began to work against her master's taint, trailing down and then up and all the way to the balls again wetting them with her cool spittle, purring as she felt them twitch every so often.

Xin held back his cum, he wanted them to taste a full load, and wanted to draw out this little bit of fun as much as possible, to test his precious Blaziken. He used her throat as he pleased, roughly and full of passion, his cock twitching and spurting thick pre against her throat. As he did this Blaziken did not gag once, instead she seemed to coo and let out muffled moans that were interrupted by his thrusting. He could feel her growing weak in his grasp though, he saw that her eyes were watering now and so he pulled free of her mouth not wanting to harm her. He was lustful and passionate about what he desired, but he would not harm his dearest pokemon, not too much at least.

Licking at his chops he took his cock in paw and began stroking it slowly, making a show of pumping his large member. Soon enough the two girls took the hint, Glaceon sitting upon her haunches tongue out expectedly, at the same time Blaziken was upon her hands and knees, tongue out as well just as hungry for the cum she had worked so hard for. Xin again teased his precious servants, passing his cock against their tongues, once each before picking up the pace. Both of them shuddered as he passed his cock against their tongues and again when he began stroking that thick cock of his, they both waited, not moving a single inch as Xin took his sweet time pumping that massive thing until finally the orgasm began.

Xin practically snarled as he pumped his massive cock, muscles tensing and bulging just a bit, cock twitching violently as ropes of thick seed spurted onto both of the girl's tongues. He made sure to give both of them plenty to drink. First he passed some of his thick seed directly into Blaziken's open beak, letting her drink deeply first before turning his cock to Glaceon, rising and moving forward to jam his thick cock into Glaceon's open maw. For a moment her eyes widened, then fluttering as she slumped upon his cock, allowing him to pour the rest of his cum deep into her throat. Glaceon might have been desiring that her master would do such a thing, but she certainly wasn't as durable as Blaziken, so after she had swallowed every drop and her master pulled away with a still hard cock she collapsed onto the floor panting just a bit, her master's loving paw upon her head, consoling her as she huffed and gulped in air.

Xin still had so much to do now. He had seen that Glaceon would need a bit of a break after he practically bred her mouth full of his cum and so he turned to Blaziken with a predatory gaze. She answered in turn by lying upon her back, spreading her legs to present her wet and twitching pussy. She had desired her master for long enough, and now that he was a large and powerful male she would finally be able to experience him, experience the sensation that was his new form and attitude. She cooed for him, digits moving to carefully spread her pussy to show her hole to him, desire welling up and over.

Seeing that his pokemon was so well presented for him and prepared for what he was about to do to her, Xin moved without hesitation over his pokemon, his strong paws taking hold of her ankles to spread them further apart before both of his paws trailed down her legs to those supple thighs that he had loved so much. Without much ceremony he grabbed onto his cock and pressed the tip to her cunt, grunting as he shoved on inside of her, groaning out as he pushed deep, the heat from her pussy immediately apparent. As he ploughed into her, Blaziken crooned and squealed, panting as her insides were pounded by that Lucario cock that belonged to her precious master.

Xin wanted to go deeper with every thrust, his pounding jolting her with every push, his mouth moving bite upon her shoulder to teste his new fangs as he brought himself as deep as he could manage inside of her. With every wet thrust his knot kissed at her entrance, his balls slapping against her as he tried with all of his might to slam his knot in as well. He wanted to breed her, to properly impregnate both of his girls, and so without hesitation he pushed and pressed his knot to her pussy, the Blaziken's leg's coiled around his hips and tugged him in closer as she yowled out her pleasure, Xin growling to her shoulder as his hands moved to grip upon her hips, his knot finally gaining entrance with a wet pop that sounded off against the trees. Even though he was already fully in her and knotted, he began passionately grinding against her, his strong grip holding her in place, his hips jolting and pushing forward with every single twitch his cock gave. At the same time he grunted feeling her insides tighten upon him further, his Blaziken groaning out, her eyes fluttering and her body twitching as she reached her climax. With her tightening like that it wasn't long before he came.

Even Xin had thought that this load wouldn't have been that large, but if anything his seed came out in larger amounts than before, the tip of his cock practically pouring a torrential amount of seed directly to his precious Blaziken's womb. As he came he grinded against his Blaziken, a hand moving to secure the back of her head, his mouth moving over her beak so they could share a passionate kiss of tongues as he filled her pussy.

Though Xin's orgasm was over, he continued rutting her, grinding against her, grinning as she cooed to his every single movement. Hearing a sudden mewl he turned his head just a bit, feeling the cool tongue of his needy glaceon upon his balls. With a grin he gave the now resting Blaziken one last thrust before beginning to pull and tug at his knot before finally pulling it out with a slick pop, his seed dripping freely from the Blaziken's gaping cunt.

When Xin turned Glaceon already had her tail lifted high in the air along with her rump, presenting her glistening cunt to her master. Striding over to her he gripped upon her haunches, pressing the tip of his cock to her entrance, making a game of pushing in just a bit before pulling out. Before long he heard the ice type whine and mewl, and so he gave her what she desired. With a growl he thrust deep inside of the Glaceon, stopping just a bit to let her stretch out. Though she was extremely tight, the Glaceon seemed to only cherish her master's cock, letting out happy little mewls and moans as he began to pump his cock in and out of her overly tight cunt. Xin shivered the deeper he went, her insides feeling so strangely hot and cold at the same time, the sensation sending shivers up his groin and into his spine. That feeling only encouraged his cock to let loose cum, but he held back, wanting to build up a proper load for his precious Glaceon who he would be so happy to see bear a child for him. Xin could only imagine how beautiful their children would look, and again he thought of Blaziken as well and how powerful their children would be. His muscle, Blaziken's fire, Glaceon's grace, it was all too perfect!

Grunting he began pumping his cock harder inside of that tight cunt, paw gripping at her tail to tug just a bit as he pumped in deeper and deeper trying so desperately to get his cock firmly planted inside of her. It wasn't long before his knot was kissing at her entrance, but he found it difficult to push further inside, his knot refusing to enter her tight and twitching cunt. The ice type's front had collapsed, her tongue lolling out as she panted and mewled, her pleasure clear though her insides were stuffed to the brim with her master's cock. Seeing as she could handle his advances, he figured why not? Muscles upon his arms and thighs flexing, he gripped tight upon her hips, the Glaceon's head turning just a bit in curiosity before her eyes widened. Xin snarled, fangs bared as with all his might he began pounding into his lovely little Glaceon's tight pussy, stretching it further and further with every single push, his knot kissing at her entrance and this time actually pressing in just a bit with every pound. At this point Glaceon shivered and mewled out loud, gasping with every push, with every thrust that her master gave her. Eventually she collapsed entirely, held up only by her master's powerful grip while she sounded off her orgasm with a loud and shrill mewl that caused her insides to clench and grow further wet. Thrusting in deeper and deeper she could feel that thick knot gaining entrance, stretching her insides before finally with a pop that massive thing stuffed her.

Xin panted and paused, eyes staring down at the handiwork he had wrought. He grunted then as he began to grind against the tired Glaceon, working his cock until finally he let loose his final load, his cock twitching with every single thick spurt. When it was all over his cock grew limp. The trio were all panting, Glaceon and Blaziken lying there stunned from the sudden intensity of their lovemaking, Xin's eyes growing heavy now as well. Gathering Glaceon he laid down next to Blaziken, taking Glaceon upon his lap, his eyes shut now, that would be enough for now.

When Xin woke, his pokemon were looking at him with content expressions from where they laid. Xin smiled lazily and yawned, hand coming up, only to notice that he was back to being a human. Still, he felt that confident and heat burning through him and so he leaned in to kiss both his pokemon upon the mouth and beak. They blinked, both surprised from the show of passion. Xin chuckled and rubbed at the back of his head, turning he saw that blue stone that had changed him lying next to them. Carefully as he could, he touched the stone, unsure of what to expect, but as he lifted it in his hands he could feel nothing coming from it, and yet he still felt the same as he did last night; fierce and powerful. With a small smile he realized that perhaps the change was still probably there, now he would love to figure out how to control that, but until then he could settle with loving his pokemon as a human. Shivering he would have to remind himself to take off his clothes when he discovered it. Blaziken and Glaceon both leaned against him, their fur warm against his skin and he chuckled, perhaps he wouldn't need clothes at all.
