This was a lovely story to read. Great work <3

Wow, quite a nice read :D Good job!

Thank you very much! Got any favorite scenes in particular?

Finally! A decent Lucario tf story! Thank you!

Conventional ‘Cario
Lucario TF
You scored a pretty good find in the dealer’s den with your friends: a stall was selling merch
conveniently themed after each of your favorite Pokémon! There were lots of items to choose
from, but among the ones purchased were a ponytail bead, a themed painting set, and a variety
pack of flavored Malasadas. The one and only item you snagged within your budget was a
high-quality, Lucario-themed shirt that was just your size. The front and back were covered in
incredibly soft blonde faux fur, like the ‘mon it was modeled after; black bands circled its
shoulders which gave way to short blue sleeves.
In your excitement, you failed to tell your buddies to stick around to see how you’d look with your
new purchase on! By the time you left the stall’s tiny dressing room, they’d disappeared into the
thick of the convention crowd.
What a bummer… Was what you would say if this shirt didn’t feel so warm and cozy to wear! You
checked yourself out at a nearby mirror, emulating some silly Lucario poses you recalled from
the anime Silly fighting poses. Striking a cool, edgy stance. Hands together like you were
channeling aura. For some reason, you hold that last pose for a while. Eyes fluttering shut. It
was so… comfortable.
The sounds of the convention faded away, and an odd sense of calm washed over you.
Somehow, you felt… relaxed and at ease. For a brief moment, something shifted in your
perception, and you saw an image of your immediate surroundings, all bathed in a ghostly blue
glow–
A fellow customer bumped into you, shattering the illusion of whatever that… sensation was.
Sound comes filtering back in, somehow even louder this time. How did things get so loud all of
a sudden? It was like a busload of people entered the convention all at once!
For now, there were more pressing matters to worry about, like figuring out where your friends
went off to! The convention center was a big place, so you weren’t quite sure where to go first,
but if all else fails you could look for them at the hotel room. Hopefully you’d find them soon…
the thought of walking so much made your feet start to cramp up.
Into the bustling sea of people you went! You maneuvered and weaved yourself through the
crowd, going from aisle to aisle in search of your companions. But they were nowhere to be
seen. You even found yourself tiptoeing to try and see their heads off in the distance, but that
didn’t work. At times you could’ve sworn that your ears picked up on their voice, twitching more
and more as you attempted to follow the source of the sound… but you found no trace of them
at all!
Eugh, your phone’s WiFI and data connection were no good either. It’d be kinda embarrassing for
everyone involved to try and get the front desk to call ‘em like you were kids lost in a store… Was
there really no other way to find them?
You scratched at your shirt absentmindedly, its fluffiness helping to calm your nerves. Every
reasonable option was exhausted, save for…
You glanced down for a second, hand still petting the blonde fur on your chest. Pets turned to
scritches, real good ones, at that. Your foot started tapping impatiently, or was it in reaction to
your scratches? L-Like a… Nnnnh-no, it couldn’t be, “that” wouldn’t work! B-But, that “thing” you
sensed earlier… Maybe, just maybe, it was real, if you just gave it one more shot? It stood to
reason that you— rather, that a Lucario would have such an ability.
Though, where would the best place be for “that”? Near the convention entrance? Nah, logically
speaking, the place with the best coverage would be as close to the center of the convention
hall as possible. Bracing yourself, you adjusted your shirt, noting that it felt just a bit tighter now,
real flush against your body and upper arms. The bottom hem like it had been tucked in real
tight into your jeans. That cramping feeling in your shoes still hadn’t gone away either… To ease
that feeling, you tiptoed off into the crowd once more.
Your “instinct” (no, nope, you couldn't call it aura until you were absolutely sure) brought you…
back to the merch stall? Or, at least you think this was the place. Nothing seemed out of the
ordinary, but you didn’t really wanna waste time by going back inside. You stood behind a pillar
separating this stall from another, to have at least some form of privacy, and so that you could
rest your aching legs and feet. Now to calm yourself, perhaps by striking that pose again? You
clasp your hands together, drowning out the sounds, and letting the world fade away.
…Nothing’s happening, but that isn’t dissuading you. You’re staying patient and resolute, and
soon enough feel “it”. Another sense, pushing its way out into reality, growing from the back of
your head. Mmmmh, it’s aching, and your heart’s racing in tandem with each pulse! The world
remains dark – you can barely make out those ethereal shapes from before.
Was this really happening?
S-Should you stop??
No! You told yourself. As irrational as this all seemed to be, it was something you were resolved
to see through to the end. Letting those sensations build up more and more, opening up your
mind to… “it”. The aching continued, like your brain and body were thinking as hard as possible.
Like all those thoughts were getting too cramped for your own head–!
Those feelings burst outwards and came rushing back in a single instant.
Your stance wavered and your eyes remained shut. And yet, this new sense of yours provided a
snapshot; a hazy outline of the world around you. For that one moment, all sorts of colors
radiated around you, and flared into auras. Somehow, your mind parsed through all of this
information to find your merry group of friends heading towards… the elevators!
Your eyes shot wide open, you step forwarSHHRRRIP!
A pair of black paws tore through your shoes, giving them some much needed breathing room.
Your paws feel much, much better! The floor felt a little cool on your toe beans, but it was fine,
you were more relieved than anything at the moment. Those footpaws were still pretty new, so it
took some getting used to. Still, with your heels raised, the slight height boost was appreciated
all the same! You wiggled your toes for a moment and headed off with a skip in your shaky step,
each one made you feel more eager to continue your search.
Something bounced along with you. Three- no, four things, actually! It only took a quick shake of
the head to confirm it: black-furred aura sensors, grown out from behind your head! That was
just enough to snap you out from your momentary stupor. You should’ve been freaking out! So
why? Why were you okay with all this? Did meddling with that aura sense give you some weird
inner peace mojo? No one seemed to mind, didn't they notice the changes?
As if to prove you wrong, you were made aware of a bump pressing at the seat of your jeans. It
didn’t take a genius to know where this was going — a tail was gonna burst out sooner or later!
Then again, who was to say that it wasn’t a tumor of some sort? That was more believable,
right? It could still- er… it… Gah! Fine, maybe you did read one of those… ‘TF stories' involving
Lucario, j-just out of curiosity… it made you keenly aware and familiar of how these changes
should progress. As a consolation, that eased the surprise of feeling black fur slowly crawling
up your ankles. At least they felt real comfy to the touch.
You cautiously walked through the crowd, trying not to bump into anyone. People were more
preoccupied ogling the more extravagantly-dressed cosplayers wandering around; there was still
a chance that you could pass off your changes as a mere costume too! Everyone else would be
deceived, but deep down, some part of you wanted to welcome the changes. B-But not here! Not
where people could see and stare! You run a hand across where your tailbone would be, patting
at the steadily growing mound in your… Huh?
That was odd. Where you would’ve expected to feel denim instead was uncharacteristically soft,
like a cross between that and cotton. Speaking of which, you should’ve been sweating buckets
with how much you’ve been walking around this whole time! Hopefully the shirt wasn’t ruined,
just need to check and—
It’s… not coming off.
Try as you might, you couldn’t feel the collar at all. T-The sleeves too! Just blue fuzz, then flesh;
where was the separation?? Your furry Lucario shirt didn’t feel quite so faux as before! Your
mind desperately attempted to register it as furry fabric, stuck fast to your skin. It tingled and
buzzed like a weird itch as the seconds ticked by. In fact, you could sense something similar
happening to the lower half of your body too! It was as though someone dumped a whole bottle
of fabric softener on your jeans, seeping in and changing the material! It felt the fuzziest riiiight
above your ankles. The cuffs there split and threaded into your skin, and around your calves,
black fur seemed to just grow right through like it was nothing! They all but started to fuse to
your legs, but it looked like these would take more time compared to your shirt.
Alas, things started to snowball, and FAST! Between the fluffy Lucario tail sliding its way down
your pant leg, black fur and skin pushing its way out from your shoulders, and the apparently
very real and very sharp spike nestled in the center of your chest. Keeping track of all the
changes was a stressful ordeal! The fur on your legs inched closer, up to your knees, and sooner
or later more drastic physical changes were on the way, like- W-WHOAH!!
Owww… with your tail trapped as it was, your balance was out of whack. Looking up, quite a few
people were bewildered by your appearance, but still helping you up to your paws. N-No, not
paws! Feetpaws! Ahh! Even your mind was changing too! Sheepishly, you excuse yourself,
brushing off any comments and questions about your realistic “Lucario-eared headband” and
the mask of black fur on your… f-face?!? Aw, come on!! So much for staying inconspicuous!
Throwing caution to the wind, you considered breaking into a mad dash for the elevators, you
were so close! But that damned tail of yours desperately tried to wriggle free from its confines,
threatening to send you tumbling down and drawing attention to yourself again. Maybe it was
worth pulling your pants off rather than risk a wardrobe malfunction…
You sense another tug... The shirt, a-and your pants! A black band of furry fabric extended and
merged into one solid pelt, forcing out a shudder as that band sticks and sinks into your waist!
Even then you felt that bizarre sense of the fluff ‘threading’ and melding right into your body…
Yet, in spite of it all, it was not an unwelcome feeling. You got this shirt to feel closer to the
Pokémon you’ve always admired, and here you were… t-transforming, beyond all logic! There’d
still be a chance to properly appreciate the changes in private… y-yeah. This wasn’t… so bad…
Heh, look at yourself, with ears all perked up, heck, even your aura seemed to be getting more
positive overall! It was enough to get your tail wagging!
Your… trapped tail. W-Wait, not too much or else it'd RRRRIIIIIIIP!!!!
Everything seemed to slow for the next few seconds. You turn to look at your rear just in time to
watch the seat of your pants fray and tear apart, and your tail unfurls from its fabric prison.
Sigh. A tailsplosion. Exactly how you’d read in fiction.
At least the pressure was gone… for the most part. The fuzzy material where your tail broke free
hadn’t caught up just yet with the changes surrounding your thighs. Your tail’s freedom brought
with it a heightened sense of urgency: the longer you stayed here, the more exposed you’d be!
The stress elicited a few rubs of your cream-colored pelt for comfort and reassurance. Soft and
f-fluffy… even your tail twitched in response as your hands pet and kneaded their way down from
your torso to your waist.
The black band of fur around your waist almost seemed to constrict, funneling more and more
mass down to your swelling thighs! Your jeans also pressed down tight to meet the thickening
flesh, weaving and melding into one. That fuzzy material on the surface split and threaded into
the skin, and with that connection made, it took on a brighter blue shade - fitting for the creature
that you were turning into. On some level, you were getting pretty excited to feel your fur more
intimately, and for what would happen next… it was enough to make your tail shake! But was it
really worth doing, especially when you’d arrived at the elevator lobby?
Moving to the back of the line, your fingers tapped restlessly against your swelling thigh-shorts.
The changes there were still ongoing, but you felt slowly more naked as the transformation took
more of your pants, not intent on stopping till it reached your waist... Who knew what'd hden
once that change is through!
The elevator dinged and your ears perked up to the sound immediately. Before you knew it, you
rushed and pushed your way through the line, ignoring the dozen or so people you ticked off by
doing so. This was an emergency, you argued! At last, you slipped through the doors and into
the elevator.
A cramped elevator.
Full of people. Bodies unavoidably pressing and brushing against your and your fur.
The other occupants stared at you in shock, but were more or less dumbfounded by your current
appearance. It was a looong way up for you, the trip was constantly interrupted by grabby hands,
and questions about that “realistic” tail and the Lucario “headband” you wore… they even asked
where to get one!! You felt all of those sensations like it was your own body… firmly removing
any lingering doubt left in your mind that these changes were anything but real.
On an unrelated note, someone noted a black spot on the tip of your nose before getting off on
their floor, and sure enough, your reflection in the elevator doors showed just that! Y-Your hair
and ears were also growing bluer by the second, encroaching across the rest of your face to
change it completely! A cursory poke of your nose revealed a wet and leathery texture, like a
canine’s… that action suddenly spurred the growth of black fur on your hands and wrists,
hellbent on connecting with the blue fluffy crawling down your arms! You futilely shoved your
hands where your pocket’s would’ve been, but the last of your jeans merged into the rest of your
body.
N-No! The change, it’s left you… u-uh… w-wwwoah…?
A brief sensation sweeps past your mind. You were… why were you w-w-worrying? There was
nothing but fur, did you get it d-dirty on the way up?
The elevator dinged, interrupting your train of thought. Finally! You dashed through the corridor
in search of your room number. The faint scent of your friends lingered in the air, they were here
not too long ago! You were sure of it, and yet there was something different about them too. All
things that you could worry about once you returned to your room!
You clicked the door shut. Finally, a chance to relax… but the backs of your hands itched
something fierce, so you gently tried to scratch them with your new claws. You could feel
something smooth and hard pushing out from the skin, revealing the signature metal spikes
Lucario was known to possess, matching the larger one on your chest.
Your nose scrunched up before an intense pressure built on your face, stretching and cracking
as that developing muzzle pushed forward and outward. Mmh! To ease it somewhat, your paws
tried to massage your canine muzzle until the powerful sensations dulled and faded away at
last…. Did that mean it was all done?
Silence followed. Hm, that seemed to be the case. And with no one to disturb your privacy…
There was nothing that stopped the wide grin spreading across your muzzle.
Y-You ACTUALLY changed! Everything was an incredible rush from start to finish… and your
aura– your aura!! It was hard to believe that you had this whole other sense now, but the
possibilities and new experiences seemed endless. Hundreds of questions flashed through your
mind. What moves did you know? Were you really weak to fire now? Could you Mega Evolve??
Would you… be able to change back?
Oh.
Uh…
Your ears and tail drooped at the thought. W-Well, if the changes were permanent, then perhaps
Pokéballs were a real thing too. Should you find a trainer you can trust and then maybe–
A knock on your door caused your aura to flash, sensors flaring up to detect who interrupted
you.
It… it was your friends! But it couldn’t be, but they were! It was hard to explain but they…
They weren’t human! Wait…for real!? You wouldn't have believed it yourself, if it weren’t for the
fact that each of you bought something from that convention stall. You closed your eyes and
tried to sense them once more, and made out a few forms… A big Zoroark, a Smeargle fiddling
with his tail, and something that was floating above the both of them… eventually narrowing it
down to an Alolan Raichu with how big that tail was in your vision.
You stepped closer to the door, but hesitated. You recognized them, but how could they tell that
it was you after all the changes? There was only one way to find out.
A wide grin spreads across your muzzle, and you swing the door open.
What follows are shouts and yips of elated Poké-speak, incomprehensible to the human ear, but
to the four of you, it’s like nothing changed at all. The bonds you shared only got stronger now
that you’ve all changed, and what awesome Pokémon everyone turned out to be! A giant, fluffy
group hug topped it all off. Now that you’ve reunited with your friends, everything is going to be
okay.
And what better way to celebrate these changes than by wowing people on the convention
floor? The day was still young — plenty of time for pictures, and to show off a move or two to the
public! Everyone races to the elevators… everyone except you.
You shut your eyes and let the world of aura come into view once more. Your friends’ auras lit up
the corridor in their own colors. Wholly unique and unmistakably theirs.
As for yours? It flared a pure and bright blue, now that you’ve fully embraced this new self. That
was all you needed to know. You break into a run, catching up with your friends right as the
elevator doors open.
This was gonna be the best convention ever!
