(F to Goodra)

Being a Pokemon Trainer wasn’t all fun and games, despite the number of games that would attest otherwise. The first problem was the travel, and the need to either stay in hotels every night or get exceptionally good at camping in wild routes. The next was taxes. And of course, the last thing was Trainers.

No, when she’d taken the three T’s into consideration, being a Pokemon Trainer wasn’t up Roxy’s alley. Which was exactly why it was so funny that she was going to dress up as her partner’s favorite Pokemon.

Unlike Roxy, Audrey was totally on-board with the ‘occasionally get mugged by a preteen’ lifestyle. She was even good enough to have earned a healthy pension thanks to her sixth badge. And that badge was thanks in turn to her Goodra. Audrey had always joked that if she’d had another one, then maybe Goosco wouldn’t have gotten his ass handed to him so easily.

Well, today was going to be that day, courtesy of a surprisingly friendly PokeManiac.

For the tenth or so time, Roxy admired the quality of her costume. It was velvety and soft on the inside, with a little bit of slickness to the outside to give it ‘the look’. The only problem was that it was a little loose around the midsection, a problem Roxy had cleverly solved by stuffing a full three pillows around her waist.

“Perfect!” Roxy tugged the top over the bundle of pillows, patting at herself and giggling.

Experimentally, she kicked her foot and giggled again at how big the boot was. Its tail shifted a little behind her, and she wobbled in place with a gulp. The costume was good, but if she fell… Would it be able to handle that?

Roxy didn’t want to put that up to chance. The last thing she’d want is to surprise her girlfriend with a half-torn outfit and a sheepish grin.

Besides, the only things left to put on were her mask and her right glove. Even her hair was pulled up into a pair of cute twinned ponytails, dyed a nice shade of purple that matched her outfit.

A flicker of doubt brought a frown to her face. What if she didn’t look perfect?

Roxy sighed, leaving the one glove on the bed. She waddled her costumed butt over to the full-body mirror in their guest room, just to make sure that everything was perfect.

With each bouncing step, Roxy marveled again at how nice the costume was. She felt light and airy, bouncing her tail behind herself without making it thump all the way against the ground. Or at least, that was her first impression.

On closer examination, it almost felt like it was getting a little heavier with each of her footfalls, to the point where she actually started to sweat. The soft lining of the costume started to stick to her skin, its velvet sucking up her sweat like a sponge.

“Oh well, it’s not like anyone else was going to wear this…” Roxy muttered, a little self-conscious.

Roxy wiped at her brow, blushing at how her bare hand came away slicker than it should have. She wiped it absently on the costume’s slick surface only to have her palm stick to her thigh.

“Huh. Maybe not so slick after all,” she muttered, trying to lift her hand. A quick tug didn’t free herself, and the risk of tearing the suit kept her from tugging any harder. “Stupid thing must have had some glue on it or something.”

Roxy waddled closer to the mirror. Her tail swished behind herself as she took a closer look at her thigh. Another gentle tug sent a ripple of motion across her hip and even her belly, and she groaned. She was really stuck, wasn’t she?

“Just my luck…” She leaned in a little closer, tail curling to help herself keep her balance. From what she could tell, there wasn’t any splotch of glue under her hand, but maybe she just couldn’t see it from this angle.

Roxy slipped her gloved hand against her stuck palm, curling her fingers to try and widen the gap between outfit and wearer. To her surprise, she could feel the back of the costume’s slick hand against her thigh. Also to her surprise was that the gloved hand was slipping against her ‘sticky’ thigh with ease.

She slipped it between her palm and thigh, and whatever had stuck her undid itself. There wasn’t even a stain on the costume. If anything, it looked shinier and slicker than ever.

“Whoa.” Roxy swished her tail curiously, looking back up to her reflection. The costume looked perfect, and her hair-antennae curled delightedly.

Roxy froze. Her hair-antennae uncurled.

Then she screamed, batting at her hair. Had some Bug-Type gotten into her hair? What was happening? Her hands slickly slapped against her locks, and soon the individual strands clumped together. More than that, they melted together. Soon she had a pair of gooey head-tails, which still wasn’t her most pressing concern.

No, that honor went to the fact that she could feel them. They were somehow as much a part of her as her arms, or legs, or tail…

Roxy froze again. This time the panic was wordless, full of dread. Something in her brain had noticed this was happening, but it had been beaten into submission by… What? How good it felt to wear this costume? How Good it felt to be heavy? How GOod it was to… How… How GOO…

When had her costumed hand pressed against her chest? Why was her other hand so tense? Why were her breasts so sensitive? Roxy’s gooey antennae swayed in time with her hips, a purple blush spreading across her cheeks.

“Sum… Sumthing’s wrong…” Drool slipped from her mouth with every word. She was getting really hot. She felt sweat dripping down her curvy sides, running past her thighs. She could see it against what should be a costume, somehow feeling it as though it was on her skin itself.

“Nothing’s wrong,” a cute voice chirped back at her.

Roxy whirled around, though her gloved hand didn’t leave her chest.

She was alone.

A small, nervous smile spread across her face. “O-okay, take it easy, girl. It’s all gooOOOd.” The second the last word slipped past her lips, her hand clenched, squeezing her purple breast. No, the costume’s purple breast? But it didn’t have breasts…

Roxy looked down to her chest, pressing her ungloved finger against it. The touch didn’t feel right, wasn’t the same as her palm. It was like the slickness of her other hand was an aphrodisiac, heightening her sensitivity.

She closed her eyes, squeezing harder, drifting. She opened her eyes and was in her room, on her bed. Her other hand just slipped into its glove.

When had that happened? Why had that happened? Roxy didn’t know. She gulped and looked at the glove, seeing the seam between it and her wrist vanish.

Then, sensation.

Roxy shivered, pulling her shoulderblades back and squeezing her fat belly with both hands. The costume’s fat belly. No, hers. It didn’t make sense, but did things have to make sense when they felt so good?

She swatted her tail against the floor with a heavy thump, curling it and uncurling it. Everything was so hot, so sweaty, so slick… She opened her mouth to moan, and her thick drool splattered onto her bedsheets.

“See? It’s better to be good,” that same voice called out to her.

Roxy snapped back to reality – or at least, whatever reality that would explain how her costume was becoming a part of herself. Or… Was she becoming a part of it?

That second option was… Well, it should have been terrifying. But instead, all she felt was anticipation.

“That’s right. Because you know the sooner you change, the sooner you get to be with your mate and his trainer.”

The voice was coming from her nightstand. Was it her PokeNav? She looked at it worriedly. One of her antennae viscously slapped against her tits and her vision blurred.

“Not there!”

Her other antennae pressed against her cheek, pushing her gaze onto the mask. The last thing to complete her. Her mask.

“Nnh… Nuh,” Roxy slurred. For some reason, having a tangible source for her changes made it easier to fight them. Or so she thought.

A mouthful of drool made her cheeks bulged. She tried to swallow it, squeezing her eyes shut. But it was caught fast in her throat. She struggled with a gulp, then another, and another. Each time she could feel the muscles in her neck tense, then stretch in relaxation.

Finally, she gulped it down, opening her eyes to find she wasn’t looking at the mask anymore. Now she was staring at the top of her nightstand’s mirror, which was currently reflecting some big, long, stretchy, purple neck.

Oh.

Roxy lowered her head, whimpering at the sight of her human face atop a body that was undeniably a Goodra’s.

“Almost a Goodra’s.”

Roxy looked back to the mask, whimpering. Sweating. Dripping with… She didn’t have a word for it. She looked at her arm curiously, only to whimper at an image reflected in the goo dripping from her wrist. If she wasn’t mistaken, it was what she’d seen at her PokeCollege commencement, back in…

The goo droplet dislodged itself, splatting against the ground. And with it, went Roxy’s memory of… The occasion. She was just thinking about it. But couldn’t think about it anymore. Why was that? What was happening?

Another droplet caught her eye, one of her learning to drive. It fell, and Roxy wondered why she was thinking of that weird boxy thing that Audrey liked to ride in. Audrey…

“Ooh, remembering your Master? Would be a real shame to forget her, wouldn’t it?” The mask called out to Roxy.

She snapped her gaze over to it, just in time to see more goo puddle at the tips of both her antennae. One was an image of Roxy and Audrey together. The other was of Goosco, when Roxy had to babysit him. Both of them were precious memories, though her costume clearly valued one more than the other.

It didn’t take a PokeCollege graduate to realize what was happening, and what was at stake if they fell. So Roxy remedied the situation as best she could, opening her mouth wide and shoving both of her antennas inside it.

Her smug, self-satisfied grin soon turned into a pleasured smile as a new sensation shook her fat body. Her goo tasted warm, with a cool minty sensation against the back of her stretched throat. Her antennas were as sensitive as her breasts, which soon joined in the chorus of pleasure as she squeezed at herself again.

“Someone fell for it.”

Roxy didn’t know what the mask was talking about. How could she? She was so hot and bothered and sweaty now that she positively soaked the carpet with her heat. Something about that was… Bad. She sucked on her antennas and fell to her knees, smacking her cheek against the table.

Luckily, she was able to keep her mouth closed. She could still remember… What? The memories were swirling together, slicking into something new and wonderful. Instead of her and Aubrey on their date, it was two goodras… And instead of her babysitting Goosco, it was Audrey pampering her.

Roxy gulped anxiously, swallowing the memories and cementing them in her belly. A new shudder wracked her fat body, and she shook off the sweat of her old life, looking blankly at the mask before her, and an unfamiliar reflection.

A scary reflection. It was like she had a human face instead of her wonderful purple snout. Roxy whimpered, about to stumble back.

“Aw. There, there. It’s okay. Just put me on, and it’ll be fine.”

Unfortunately, the mask was designed for humans, and Roxy’s new mind was totally incapable of grasping how to make that work. So she dropped her face onto it, rubbing her sweaty cheeks against it, melting it into a gooey puddle.

“Close enough,” the voice hummed, bubbling away with a laugh.

Roxy whimpered, staining her cheeks with the goo, smearing her face against a nightstand that used to be hers. And, luckily for her new brain, her face stretched with the motion. Her nose rounded, pulling away from her jaw. Her cheeks took on adorable green circles. Two smaller antennae sprouted from her forehead.

“Gugghhh… Goo… GOO!” She babbled like a nitwit, eyes glazed slightly. Her brain felt so tingly and fresh, which was a little silly because she’d had it her whole life and-

“Gooxy, you home?” Audrey’s voice called.

Something about her voice made Gooxy excited. It was weird, because that was the kind of excitement she usually associated with breeding. Oh! It was probably because Goosco was with her! Of course.

The new Goodra eagerly rubbed her belly, waddling away from a room that was once hers. The echo of her own laughing voice followed her out, then faded away.
