Jason sat listlessly, staring vacantly at the clock on his stove as he waited for his friend Gabe to ring the buzzer to his apartment. He’d been so excited to show Gabe the little gift he’d picked up for him online a while ago. Jason was well aware Gabe was having a rough time at work and in his personal life, and while it wasn’t much, it was sure to cheer him up. It was all he could do for Gabe, but it was gonna make him quite happy to see Gabe’s smile when he opened it. 

At last, the buzzer rang, and Jason sprang up, pressing the button which allowed the automatic door to open for his buddy. He heard Gabe walk slowly up the stairs, that distinctive footfall of his, a bit too heavy, with more weight on one foot than the other, an old sprain Gabe had told him about. He’d been here countless times, enough for Jason to know his walk.

“Hey, man,” Gabe said, clearly exhausted as he took his shoes off. Jason rushed out of sight without a word, not stopping to see his buddy’s puzzled expression, returning with a small box that he’d had waiting in the other room. With a smile, Jason set down his present, a small carefully wrapped box. 

“Here ya go Gabe, happy birthday! I think you’re really gonna like this,” Jason said with a smile.

“You didn’t have to do that, man,” Gabe said as he picked up the carefully wrapped package. Tearing off the red wrapping paper and opening the lid, Gabe found himself wondering what Jason had thought to get him. He hadn’t expected anything, hadn’t even made a point to mention his upcoming birthday. They were both fairly poor, working minimum wage jobs in this crappy economy, and any celebration would simply be their usual drinking and gaming. 

“Oh, wow, it looks like…is that a model fire stone?” Gabe yelped as he picked up the tiny carved stone neatly wrapped in the bottom of the box, careful not to damage it. He found it surprisingly warm to the touch, even after being in the box. “Where’d you get this?” He asked, feeling its warm surface with his palms. Jason must have had the box sitting under the sun or by a heater. Oh well. It was clearly no worse for wear. The craftsmanship was amazing; Gabe would have sworn it was real if such a thing were possible.

“I ordered it from a website that’s got a bunch of cool video game stuff.  A friend linked it to me. I figured you’d like it cuz you like Pokemon so much! What do you think?” Jason said with a grin, convinced he’d made a good choice. 

“It’s beautiful man! Thanks!” Gabe said as he held the stone in his hand, walking over to give Jason a quick hug. Jason squeezed him tightly back, making Gabe smile. It really was a thoughtful gift and had really brightened up Gabe’s day. 

“I’m gonna put it beside my Growlithe plushie!” Gabe said with a giggle. 

All the while, Gabe’s hand felt slightly warmer, as though he was holding something heated. Curious, Gabe opened his palm to see the stone glowing. “Hey cool Jason, it glows too? I must be evolving! Maybe tomorrow I’ll wake up with an Arcanine plushie!” He said, with a giggle.

“Hmm?  Oh, that’s pretty cool actually, I didn’t know it glowed!”  Jason said as he leaned in for a closer look, fairly sure he could feel the heat radiating off it. 

He then noticed Gabe’s arm trembling slightly, the skin beginning to redden as though it really was heating up. “Hey is that thing getting hot?  I think I can feel it from here.”

“Fuck…yeah…it’s getting really warm… owww! Ouch!” Gabe yelled as he dropped the glowing red stone onto the carpet. He stared at his hand, swollen and red as it began to itch, reminiscent of a bad sunburn. “Does it have batteries or something? Fuck that’s hot! Hope I didn’t break it…” he added, embarrassed.

“Oh shit!  Are you okay?  I’m sorry man, I didn’t know it got hot. I thought it was just a regular model…” Jason said, the guilt evident in his tone. He then looked down at the fire stone as the light began to fade. His gaze turned back, more concerned for Gabe than the stone. It was just a toy, and from the cry of pain, it sounded like it might have hurt him. Hoping Gabe wasn’t mad, Jason was surprised when he noticed something odd out of the corner of his eye. The reddened area had turned orange with… what the fuck?

“Oh shit, what the hell is with your hand!?” Jason yelled as he watched what looked like orange fur sprout up around Gabe’s fingers like fast-growing weeds. It soon peppered the backs of his hand, and the hairs of his upper arm seemed to be altering as well to match!

It was soon worse than that, however. Gabe’s nails were thickening and lengthening while his palms blackened, turning rough. The sight of them, as impossible as it should have been, reminded Jason of paw pads! The shape of them was reminiscent of any dog paw he’s seen, though never expected them to be part of his friend’s anatomy!

“What the fuck?!” Gabe yelled in response as he watched the patch of orange fur sprout on his hands. There was a heat radiating from his chest as the itchiness spread, though he was too engrossed by the sight of his nails thickening, his palms darkening enough to notice. There was a dull ache as his nails thickened, the tips forming points as they expanded the circumference of his digits. 

“It looks like fucking fur and claws? There’s no way…” Gabe moaned, his thoughts racing. There was no way it was possible, but the orange fur clearly brought his mind to one place. A familiar form came to mind, though not one that he’d seen in the real world. Such should have been impossible! And all this from a model?

Jason stared in horror as the fur spread farther up Gabe’s arms, themselves beginning to bulge as though snakes were writhing underneath. The effects weren’t just confined there, however. He could clearly see how black Gabe’s nose was, his jaw starting to stretch forward as his teeth sharpened and white fur crept up his neck. He was changing so fast, and the mental image came to his mind, one that left him terrified. 

“Oh fuck!  It does look like fur! Orange fur…did that fire stone- no fucking way!” Jason yelled, knowing Gabe must have been thinking the same thing. The orange fur could belong on a tiger, but the pattern was all wrong, it looked too much like what Jason would expect an Arcanine to look like. Even though he would never have expected to see one in the real world, nothing else seemed to fit!

The sensations from all over were leaving Gabe powerfully confused and frightened in equal measure. Gabe wanted to reach up to touch his face, to feel what had happened to his visage. But his palms were thick and calloused, leaving him staring in horror, wondering if he’d even feel anything again with them. Still, he could feel his jaw aching and cracking forward as his facial hair grew out, like several days of growth without shaving. His entire body felt warm, itchy as the fur, actual fur, continued to crawl over his changing flesh. 

Needing to see what was happening, Gabe ran into the bathroom. In panic, he kicked the fire stone accidentally and sent it skittering into Jason’s bedroom, before staring at the alien reflection in the mirror. It was already altering to a frightening degree, making it harder to discern himself in the increasingly canine visage. He watched helplessly as his canines continued to lengthen, his jaw extending as he rubbed at his warm, itching chest.

“Fuck I look like a dog…like a…Jason, don’t touch the stone!” Gabe yelled. He at least hoped his friend would have enough sense to realize it was the only possible catalyst for this horrific transformation, as impossible as it was. 

“This can’t be fucking real…Pokemon aren’t real! Why is this happening to me!?” Gabe yelled. It was the only conclusion for the source of the changes, though there should have been no way. Yet, what other explanation was there?

“What the hell is going on!? Gabe!?” Jason called back as he ran to the bathroom in time to see the fur spread to Gabe’s face. Even stranger, his ears were becoming more pointed as they moved up his head. They looked more like the ears of some sort of canine, not the human that Gabe should have been!

All the while, Gabe could feel his muscles ache as they grew larger, his clothes getting tighter from the already present growth. “Oh my god! You’re turning into a-a dog!  Or maybe an…fuck, can I do anything to help!?” Jason asked, reaching out and grabbing Gabe’s shoulder, which immediately burned his hand. Jason yelped in pain and staggered back as heat quickly spread up his own arm and started to flow over his entire body.

“Jason, are you okay?” Gabe growled a little as he staggered forward, feeling the muscles in his chest strain and bulge. Yet, he was not prepared for the sight before him. In shock, Gabe watched as his friend’s hand began to redden…to darken like his own…

“Fuck, Jason it’s happening to you too!” Gabe yelled as patches of orange fur overtook the back of Jason’s hands, while his nails started to grow sharper, thickening to cover his fingertips.  

“What the hell!? Nooo!” Jason shouted as he raised his hands. Yet, he could do naught but watch in horror as his nails sharpened into claws and darkened to black. Worse, the changes were coming faster, orange fur spreading up his arms as he felt his skin itch and muscles ache with growth and change.

“Fuck we have to make it stop!  We’re turning into… Arcanines!” Jason whined a little as their changes continued to progress. Gabe’s lips started to darken to black as a tear opened up in his shirt, the size of his form larger than it could handle. Worse, his tailbone began aching as something pushed at the back of his pants. Black stripes could clearly be seen in familiar patterns on his arms, and white tufts on his elbows as the fur spread down his thighs. Ankles stretched backward, his legs changing shape as his toes begin to splay.

“Grrr… it’s getting rrrorse…” Gabe growled as his body heated up with growing fur. He watched Jason’s face, too, start to change, his nose darkening as a white tuft of fur poked out under his collar. His teeth start to grow as well, poking out between his lips. Gabe did a double take; though they were certainly canine teeth, they didn’t seem quite as large as his own. In some ways, he found they looked rather cute…

“J- Jason! Rhat ras the site rou used? Can we rrall rhem?” Gabe yelled, hating the canine inflections that were getting into his voice. 

“Aaagghhh I don’t know! I’d have to look up the number- aaggh fuck! Why am I changing?  I didn’t even touch it!” Jason groaned as he felt his muscles aching intently.  

Gabe’s muscles continued to swell as well, his shirt split open in multiple places from the force of his new size. His now more muscular, black-furred chest showed through, and his pants followed suit, muscular orange-furred thighs showing as a very furry white tail pushed out the back. He was putting on pounds of muscle at a rate the envy of any bodybuilder. He might have found the sight welcoming, if not for all the fur and the tail!

“Fuck it’s not canninnneee…stopping!” Gabe growled as he felt something tugging at his spine, something he could wriggle a bit as it split through his pants. He had a tail, a fucking Pokemon’s tail! How was this possible? By this point, his pants were forfeit, tearing apart, and he reached down to rip them away, to alleviate his discomfort. His warm, burning skin heated the material, making it easy to remove. He panted in relief as he realized he was down to his underwear in front of his best friend. Though, rather than being embarrassed, he found himself more…confident, and comfortable. In fact, to his surprise, the change was actually starting to feel… good…

Watching his friend curiously, Jason’s face continued to alter as his ears started to round and a distinct white tuft poked out from his chest. The image did not invoke the visage of an Arcanine, not exactly. Stranger still, Jason didn’t seem to be getting nearly as large as Gabe, though his stature was already much smaller. That and his ears and snout looked different somehow….

“Fuck shit! Why is this- erff!  We gotta…find that number!” Jason yelled. 

Though instead of looking through his phone, Jason found himself unable to break his gaze away from Gabe, watching in horror as his friend changed further. Gabe’s tail grew longer, wagging and thrashing the thick, poofy hair. Thighs and calves thickened as the orange and black fur covered his legs. Toenails sharpened into claws as his toes themselves thickened, webbing sticking them together as they shrank into stubs. Nostril’s nose became completely black and canine, slits sliding up the sides and breathing in the strong odors of fear in the room. White fur coated his muzzle with a stripe of white up the middle of his face, and his eyebrows and hair slowly faded to white to match.

An odd scent caught his changing nose and Gabe sniffed the air, curious as to the source of the intoxicating spicy aroma. It was then that a surge of lust hit him all that once, nearly making him stumble back. “Oh fuck!” Gabe yelled, feeling his cock lance in his underwear. It was massive now, far larger than he recalled it should be. Stranger still was the intensity of arousal, seemingly out of nowhere. What the fuck was turning him on!?

Jason, meanwhile, let out a whimper as he felt his body change further. Though his clothes were tighter to match his frame, he wasn’t as big as Gabe. All focus on his friend, Jason watched as Gabe’s eyes slowly changed to a deep red and longer white hair grew on his lower legs. Gabe was almost completely an Arcanine now, or at least some kind of Arcanine man. 

It was then that Jason finally noticed Gabe’s underwear bulging noticeably, starting to tear a bit as his cock stretched it out. “G- Gabe? What’s going on!? Ack!” Jason shouted as his won jaw ached and stretched further forward.

“Fuck I don’t know…I’m so…damn why won’t it go down!?” Gabe yelled as he tried and cover his throbbing cock in shame. Yet, he couldn’t stop staring at his best friend’s face. The way Jason’s hair was lightening from his normal black, growing smaller, more like a mohawk. The way Jason’s face stretched out into a muzzle, his lower face growing white fur to match his hair, his eyes slowly brightening to a deep blue. His fur was certainly darker, not nearly as coarse as Gabe’s own. Gabe found he wanted to touch it. Jason looked so damn cute as his black nose twitched and breathed in a nice musk that…no! What the hell was he thinking!?

“Why won’t this…fuck agh! Make it stop! I don’t want to be an arrrcanine!” Jason whined as his shirt started to split in a few places. It exposed his white belly fur and darker orange fur on his back and sides, a different fur pattern than Gabe’s own.  

Meanwhile, paw pads were forming on Gabe’s feet as they became completely canine, total paws, unlike his still-usable hands. His underwear started to split and tear more, a black furry sheath encasing his balls as his cock darkened to red, getting thicker as the tip became more pointed. Under his black chest fur, a second set of nipples grew beneath his first previously human pair, making him wince for a moment from the further arousal. 

“Fuck…it won’t stop!” Gabe groaned as he continued to change. He moved his hand to his chest to feel the strange growths on his stomach, only now aware of the extra nipples he had developed. Rubbing his chest, Gabe could feel how sensitive they were, making his larger cock leak simply by ribbing them. He knew Jason could see it now, but he no longer cared, not with the sheer pleasure they were providing him. The scent was too nice as Gabe felt a third set of nipples growing underneath the second pair.

As though a catalyst to further turn him on. Gabe watched as Jason’s shirt ripped slightly, his orange fur and black stripes showing through. Jason’s muzzle stretched forward until it was almost fully formed, fangs visible as his nose blackened further, looking more canine. His legs were bulking up with muscle now, the changes spreading all over his form. Best yet, his form seemed to be producing more of that lovely canine scent. Jason was starting to look more familiar, he wasn’t as muscular as Gabe was, and his fur looked different, almost like Jason was turning into a… 

Gabe’s cock was starting to leak pre into his underwear as they split open more and more, his member throbbing hard. Tingles of pleasure shot through Gabe’s body as he touched his newly forming nipples, his pecs and abs becoming more defined as they showed through his thick black fur. Soon a fourth pair of nipples appeared on his muscular chest, making his cock surge as the base of his shaft swelled out into a thick knot. As his body finished growing, his massive canine cock tore through his underwear, thick, red, and throbbing.

Jason’s eyes widened as he saw this, and he felt his own cock twitch slightly. “G- Gabe!  Wh- what are you doing? Why are you so…horrrrny!? Ah, fuck…gotta stop this…don’t rrrrant to be an Arcanine!”

“I can’t…fuck…something smells too nice…and you look…you’re so damn cute!” Gabe blurted out as Jason’s face continued to reshape, the white fur covering his stretching jaw, while orange fur covering the top half of his face. Jason’s shirt stopped tearing, the musculature seemingly complete, save for the patches of fur still growing thicker underneath. White fur covered his slim but muscular chest, his pecs and abs showing through, but clearly not as big as Gabe’s as orange and black striped fur covered his back.

“Jason…you’re not an AAAARRRRRCC-canine, you’re a Growlithe!” Gabe exclaimed as his friend shivered, clearly feeling his own member tent in his pants as his upturned nose started to sniff the air.

Jason groaned louder the more he changed, and as his nose became more canine, a spicy masculine scent filled his nostrils, making his cock surge in his pants. “Hey wh- why am I- w- wait, cute? A grrrowlithe!? Noooo!! I don’t want to be a GROOOOWWWL- growlithe either!”

 He tried to cover his throbbing bulge as black pads formed on his palms and fingertips, something pushing at the back of his pants, his spine feeling like it was stretching. Was he growing his own tail, too? Jason didn’t want to have a tail, didn’t want to be changing into an anthro Gorwlithe. He wasn’t sure what was worse, changing or being a smaller Pokemon than his friend!

Gabe, too, sniffed the air, trying hard to resist the urge to get closer. He wanted desperately to touch Jason’s face, rip those pants off and expose his tail, and maybe that changing coc- no! What was he thinking!?

“J-arrrrcaason…I can’t… I’m sorry… I just want… a little sniff,” Gabe said as he took a step forward. Part of him was ashamed and knew he shouldn’t want this, but another part of him, erupting up from under his changed psyche, said otherwise. Jason was his pup, his Growlithe to own, to do with as he pleased. Why shouldn’t he go to touch the smaller male if he wanted to in the moment?

Jason backed away as he saw Gabe stepping closer, his cock throbbing like Jason’s own, still encased in his tight pants. Jason felt the back of his pants start to split as the growth pushed against it, his new tail growing longer and threatening to tear through his pants. “A- A sniff?  Wh- what are you d- oooooh fuck…” He moaned, his own body betraying his needs. The scent that was making Jason throb kept getting stronger, and he soon realized it was coming from Gabe.  

Why is it making my cock throb so much!? Jason thought. Gabe is a guy! And why does he look so sexy- wait…what’s wrong with me!’

“Jason…you’re my…arrrrrcaaanine…mine…no…why do I…you smell so… arrrcaaannnn!” Gabe yelled as his cock throbbed and spurted more pre all over his nearly fully grown fur coat. He couldn’t help but sniff Jason’s spicy canine scent, rubbing frantically at all his nipples, massive red rocket leaking. He took another step forward, wanting to get in closer, to smell his new mate better, as was his right… 

The orange and black fur continued to spread down Jason’s legs as he felt his cock leaking pre into his pants. The sight and smell of Gabe’s Arcanine body just kept making Jason hornier.  He wanted to reach out and touch Gabe…rub his alpha’s nipples for him…sniff his fur- No no! He had to stop thinking like this!  

“Aaaggghhh what’s happening to me!? Why am I ggrrroowwwlllithe…fuck…why am I becoming a Grrrowlithe!? Why do you smell so goo- noooo!”

The sound of Jason’s voice and the scent of his lust was all Gabe could bear. Jason was his, after all. And his resistance was all the more adorable. Gabe reached in, gripping Jason’s arm as he took a deep sniff of the canine fur on the smaller man’s armpit. He felt his cock spurt pre once more at the musky scent Jason’s sexy Growlithe body was giving off. He reached down to nibble on Jason’s ear slightly, licking up his orange fur and running a pawed hand in his smaller mate’s ruff.

“Such a cute pup…a-arrrrrccccaaaanine…good pup… don’t you like my smell too, Jason? I arrrccccaaaanine smell that you do…”

“Gabe wait…we’re not Pokemon…we’re not gay…this isn’t g- grrrowwllithe…no…this isn’t right… mfff!” Jason panted as his pants tented hard from Gabe’s muscular sexy form pressed against him. Feeling Gabe’s paw hand stroke his ruff made Jason blush, and he shivered softly. He wanted to press his nose to Gabe, to sniff his fur, lick his nipples. Jason could feel a second set of nipples start to appear beneath his white chest fur, and he let out an eager moan. He wanted to resist Gabe, but it was so hard to think of why. Jason placed a paw-like hand on Gabe’s chest as he felt his legs creaking, his ankles starting to stretch back as the orange and black fur covered his legs. “Maybe just…a little touch…?”

Gabe took Jason’s pawed hand in Jason’s own, and ran it slowly over his first set of nipples, moaning at his new lover’s touch. He watched as the last bits of change took hold of Jason, his legs bulking up with muscle, his cock stretching even more, as red and canine as Gabe’s own. Jason’s fluffy white tail pushed out and tore through the back of his pants finally, growing longer and wagging eagerly. His ankles stretched further back, his legs becoming digitigrade and toes splaying into canine paws. Rough black pads grew on Jason’s toes and the bottom of his feet as his toenails slowly darkened to black and sharpened into canine claws.

“That’s… rrcaaninee…so good…” Gabe moaned as he removed his paw to rub his second set of nipples, letting his pup explore on his own.

Jason moaned as he felt his own third and fourth sets of nipples sprouting on his chest. He panted and huffed as his ankles stretched back and his tail wagged behind him. His torn pants began to feel restrictive, and Jason stripped them off, letting his cock throb in his undies. He pressed his nose to the Arcanine’s chest and breathed his scent deeply before licking Gabe’s original left nipple, sucking it a bit while stroking the muscles beneath Gabe’s black fur. “Fuck… you’re so grrroowlithe…sexy…know I should rrrresist…but don’t want to…oooohh…”

“Why should you…arrrcanine…resist…you’re my pup, aren’t you?” Gabe growled, feeling more confident in the words as he moaned and panted. Reaching his pawed hand to rip off his pup’s shirt, Gabe exposed Jason’s furry chest and developing nipples. He rubbed them slowly, gently, smiling as Jason’s eyes went wide in pleasure. “That’s a arrrrcanine…good…pup. You deserve arrrrrcanine reward…for being a good pup…”

Jason gasped and blushed hard as he felt Gabe rubbing his sensitive nipples. The sensation sent his cock to surge and spurt pre into his boxer briefs. Unable to hold it back anymore, Jason relented and pulled them down to let his cock free. The words were powerful in his mind, and despite his earlier hesitation, Jason wanted nothing more than Gabe’s approval. “Y- yes…I’m your pup…and g- grrowlithe…you’rrrre my alpha…”  

Eagerly, Jason stroked down Gabe’s abs before rubbing his lowest nipples gently. There was a powerful compulsion to pleasure his dom, wanting the Arcanine man to moan and whine his pleasure. In a sign of submission, he then smiled up at Gabe and blushed before leaning up to lick his chin. “You’rrre so grrowlithe…so sexy Gabe…” he said softly and moaned a little as he felt the base of his cock bulging into a knot like Gabe’s. He loved his canine cock, but more than that, found himself wondering what it might feel to have one inside of him…

Gabe leaned down to lick his pup’s forehead, rubbing his developing nipples as Jason returned the favor. He raised the smaller man’s muzzle and lowered his own, delighted at the need reflected in the other man’s eyes. Gently, Gabe pressed his blackened lips to his lover’s, pecking experimentally before diving in. He wrapped his furry arms around Jason’s lean Growlithe body as he kissed him deeply, tongue reaching into his muzzle to explore his new mate further. Gabe felt their cocks bob together, the released heat from both their bodies turning him on more than anything had a right to. He could taste his mate’s mouth, smell his pre, the embrace making both men more aroused than either could have imagined. 

Jason continued to blush hard as he opened his muzzle, letting Gabe’s tongue in and moaning softly as his tail wagged. He coiled his tongue with Gabe’s as he kissed Gabe back deeply, running his paws up Gabe’s chest and around his shoulders before hugging him tightly. With some excitement, Jason felt Gabe’s cock throbbing against his own, and he wiggled his hips a bit, rubbing his twitching member against Gabe’s. All the while, he maintained their passionate lip-lock, pressing his muzzle to Gabe’s as he tilted his head up into the kiss.

Gabe reached down with his new paw, trailing it along Jason’s stomach and groin before resting it on his cock, gently gripping the slightly thinner yet longer member and rubbing it against his own in tandem with their thrusts. In response, Jason shivered and murmured softly as he moved his paw down Gabe’s chest, teasing each one of his right nipples until he reached his groin. Excited, Jason fondled Gabe’s large furry balls a little before gripping his thick canine member. Jason then pressed it against his own as he wiggled his hips, feeling Gabe’s cock pulse as it spurted pre. Hardly unable to stifle a moan, he kept up their kiss, lust skyrocketing with each passing second. 

Gabe kept the kiss going for what seemed like an eternity, awash in sensation as their bodies rhythmically flowed together. He continued until he could go no more, the need to breed his new mate overwhelming. His cock was throbbing and aching at the mere notion of being firmly planted in the smaller Growlithe man’s tight pucker. With elation, he could see, hear, and smell how much his pup needed it, too, feeling compelled to tease his Growlithe boy beforehand so that both their orgasms might be all the better.

As Gabe broke the kiss, Jason looked up into his eyes, shivering in anticipation as he rested his paws on Gabe’s chest. Jason loved playing over his dom’s body, stroking his muscles gently and exploring all they had to offer. The kiss was amazing but he needed more…needed to give himself to Gabe….  

It was clear to Gabe that his pup needed to make love as much as Gabe desired. Whatever force had changed them filled both changed men with new instincts, and it suited their roles well with the bodies they had been given. “What do you want pup? What do you caanine…crave? Tell me. Perhaps I’ll arrcanine…grant it,” Gabe said, as much a dom master as he was a tease in the moment. 

The instinct to submit to his alpha and take his cock inside him was too great, and the mere thought simply made his cock leak more. There was no question in the words before he said them. “I want to have you inside me, Gabe…I want to take your grrowl…your cock deep inside my tail hole.”

Gabe stared down at Jason’s Growlithe face hungrily, all notions of hesitation wiped from his mind. Jason was his pup, his pet, and it was proper that he knew his place. “Then present your tail hole forrrrcaine my inspection pup. Show me how badly you need me. How much you want to please your arrrcanine alpha,” he whispered, words dripping lust. 

Jason tried to keep the blush out of his cheeks as he stared into Gabe’s dominant face, biting his lip.  He wanted nothing more than to please his alpha, to show Gabe he was a good pup, that he knew his place. “Yes alpha…I need it bad…I want to show you grrowlithe…show you how much I want to please you…” he murmured as he walked to his bedroom across the hall, beckoning for Gabe to follow. With eagerness, Jason leaned over the edge of the bed, spreading his legs slightly as he raised his tail. “Like this alpha?”

Gabe followed close behind, leaning in slowly towards his mate on the bed. Part of him wanted to prolong their encounter but another was overwhelmed with a need to mate and spill his seed. He lowered his nose towards Jason’s exposed tail hole, the scents from his changed body overpowering Gabe’s enhanced senses. Touching his nose to Jason’s rump, Gabe inhaled the heady scent of Jason’s new canine glands deeply, cock leaking from the aroma. 

Feeling Gabe’s nose pushing slightly into his tail hole, Jason shivered slightly, letting out a moan as he spread his legs wider. It only made Jason want it more…made him want to feel Gabe’s thick cock buried deep inside him. All hesitation about his form or sexuality was erased in that moment, and Jason gave himself over willing to the Growlithe he had become. “Ooooh alpha…take me…I wanna grrowl…feel you fill me with your seed…”

Gabe savored the scent of his mate’s need before giving a few thick licks, coating his ass with spit, in preparation for the virgin ass to take his cock properly. Jason shivered as Gabe’s tongue lapped at his tail hole, letting out a small moan that only made Gabe more eager to breed.  Gabe took his raging red rocket gently in his paw and lined it up with the needy Growlithe’s hole, gripping his sides to steady them as he pressed his tip slowly into the warm eager opening.

Jason panted softly as he felt Gabe’s cock pressing against his anus, his own cock surging as Gabe’s tip pushed in. He reached down to grip his knot, moaning as he spurted pre onto the bed. There was an urgency in his voice that made Gabe all the more aroused, turgid cock bouncing on his groin. “P- put it in alpha…I grrowlithe…I need to have you breed me…”

“That’s arrracanine…good pup…take your arrrcanine alpha’s cock…Grrret…rrrready…arrrcanine…” Gabe growled as he shoved his bone-hard shaft into Jason’s eager asshole. Panting and growling from the sensations of being gripped tightly by his needy lover, Gabe held himself steady, letting Jason get used to his canine meat.

“Oooh fuck g- grrowlithe…it’s s- so thick!” Jason moaned as Gabe’s shaft stretched him painfully, his pre lubing up Jason’s insides as his cock throbbed inside him. Slowly the pain faded as Jason became accustomed to Gabe’s size, and the pleasure made him shiver as Gabe pulsated on his prostate. Jason blushed hard as Gabe’s paw wrapped around his own paw gripping his cock, helping him stroke while Jason grasped the sheets with his free paw. “Hnnggff… it’s so good…” Jason muttered, unable to imagine being fucked could feel this good!

“Arrcanine…so tight…so good…grrrrr…” Gabe panted and growled as he sped up his thrusts. Jason’s inexperienced walls were taking him expertly, as though both were practiced dance partners. Jason moaned as their balls slapped heavily against each other, Gabe’s thick canine knot pressing insistently against Jason’s already swollen asshole, seeking entry. “Grrr take my…arrrrcnine…knot…pup…” Gabe growled, knowing the sensation would likely make him cum but unable to hold it back. 

Jason moaned and whined as Gabe ground into him, his tail hole clenching tight on Gabe’s shaft as he pushed his ass back, his tail brushing against Gabe’s chest. He spread his legs wide as he stroked his own cock faster and faster, letting his asshole relax as he prepared for Gabe’s knot. “G- grooowlithe…y- yes please alpha…I wanna feel your kn- knot inside me…”

Gabe wagged his tail as Jason’s own teased his chest, tickling his nipples and eliciting a deep-throated moan from the larger man. Gabe rammed with all his might, rewarded with a slick plop as his heavy knot slid in all the way, tying them together.

“So close…take my…arrrcanine…cum…take it!” Gabe growled as he felt his balls start to swell. The sensations threatened to overwhelm him, but in the moment he wanted nothing more than the dominate the smaller Growlithe, cum in him as was the Arcanine’s right!

Jason gasped as Gabe’s knot pushed past his entrance, and he felt the intensive throbbing and pulsing against his prostate grow beyond his ability to take. His tail hole clenched tight on the base of Gabe’s cock as he felt his own balls swelling like Gabe’s. His body was literally trembling with pleasure as his orgasm grew near. Furiously, he stroked his cock as it spurted pre all over the bed, preparing to spill its contents. 

“Oooooh Gabe! A- Groooowlithe! A- alpha! You’re so big…I’m so close! Gonna cum…  pl- grrooowlithe… cum in me alpha!” He managed unable to hold it back. 

“I’m gonna…grrr…AAARRRRCCCAAANNNIINNNEEE!” Gabe growled as he felt himself fall over the edge. Violently, his cock throbbed and delivered shot after shot of thick cum into his lover’s rump. 

“GRRRRROOOOOWWWLITHE!” Jason yelled, feeling Gabe’s paw grip him tightly as he came hard, spraying Gabe’s paw and his bed with several hot loads of seed. His vision whited out, and his body trembled as waves of pleasure rocked his body, the climax more intense than any he’d experienced as a human. If this was what it meant to be an anthro Growlithe, and gay, then…

After his orgasm finally died down, Jason stood there panting, feeling the weight of Gabe on top of him, the warmth of his seed deep in his bowels. He felt submissive, eager to serve the bigger man. Part of him chuckled; he had given his friend a happy birthday, after all, it seemed. 

Both changed men lay there, Gabe still stuck inside Jason, filling him with small tremors of pleasure. Gabe couldn’t quite pull out from Jason’s grip, but that was fine with him. It felt right for the two of them to be tied together in such a way, and they enjoyed the intense heat of their buddies, comfortable with it in a way that likely only fire Pokemon could know. 

After a long while, wrapped in each other’s embrace, both men spied the stone on the floor beside them, glowing faintly as its magic finished their transformation. Jason had a passing thought; if he touched the stone, would he transform into an Arcanine like his new mate? Gabe, it seemed, had a similar notion. With a swift movement, he leaned down and grabbed the stone, clutching it tightly and pulling it away from Jason, but not before taunting him with the life-changing item. 

“Now, now pup. Maybe someday I’ll make you an Arcanine like me if you’re good. But for now, I’m happy with you being my little Growlithe bitch. Serve me well, and maybe I’ll let you touch the stone.”

“Y- yes master! Growlithe!” Jason barked as the power trip turned on Gabe once more, and his thickening cock began to swell up within Jason, preparing them both for a second round.
