Good news: I've finally finished a fic after about a year! Bad news: it's this idea that like, only two people are gonna read. Show that ended in 2017 + two minor characters that rarely appeared = very little draw. Then add in my list of tags and we get even more niche. Still, maybe the two of you will like it! For anyone that happens to check this, I put together a gallery of pictures for the two characters, setting, and a little inspiration.

"That conniving witch!"
Kelly Burkhardt simmered in her rage even as she occupied her hands with her burgeoning tits. They grew, and grew, and grew, boob veins glowing a faint green to signal foul magic at work. Inch by inch, they stretched her once very loose black shirt until an abundance of cleavage made her wesen-hunting garb look like a skank's concept of modesty.
She knew what happened the second she felt a pinch on her exposed neck. A single dart, modified from a typical phialam de ira, pumped her blood full of zaubertrank. She knew not its contents, but its effects weighed heavy in her palms. Too heavy. Despite her Grimm strength, her thin little arms couldn't handle the strain and struggled to keep them aloft in a slowly losing fight with gravity.
"Must not... give... in..."
She drooped forward. Every part of her struggled to escape her fate. If she moved fast enough, bundled her pair in her arms and rushed for the door, she might reach her base in time to counter this curse and return for her vengeance. She scowled, fuming, taking fragile steps fueled purely by rage. In moments like this, her forehead scar throbbed to match her frustration. An oily coating across her face magnified its sense of tension, pulling its skin taut, pushing her cheeks higher and chin tighter. She could make it. Only a few more steps out the kitchen. Past the stairs, through the front where she came in. She breathed heavier as she packed on more pounds. Slower, but steadier. Barely lifting her feet, as she shuffled onward, ignoring her own pathetic state in the silver-framed mirror ahead.
"Get it together, Kelly. You're a Grimm. You've faced worse. Not much further and you'll- FUCK!"
With a crash, her breasts knocked over trays, broke bottles, decimated everything on the kitchen island table until her pair rested on cool black granite. A sigh of relief escaped her lips, low and long and loud, eyes closing to the simple pleasure of tension taken off her back... until her shirt ripped open. Straight down the middle, the tear crept rapidly until her jugs burst free. Their paleness contrasted her scars from many battles, laid out plainly, each telling a story. A small thin line toward the top came from a decades-old gash received in her first fight with a stangebär. A long one down the side of her left tit showed a close call with a powerful blutbad. A clever, vicious fuchsteufelwild left its claw marks on her with two opposing punctures on her right breast, the closest anyone got to manhandling her.
Yet, these signs of a long-lived hunting career lost their notice beside her nipples. The once smaller, modest brown nubs had grown into big fat udders. Firmer, thicker, harder, they changed in size from dimes to quarters to teacup saucers in mere minutes. They complemented her eyes and hair in shade as they poked out obscenely, turning her normal features into accents in her body's quest to make her look like an oversexed bimbo.
Changes which at least one person enjoyed, if not Kelly herself. A vile, mocking laugh erupted from behind the seasoned Grimm. Over her shoulder. A few feet away. Unable to turn with her twin burdens pinning her in place, she angled a nearby silver platter and glowered at what she saw in its reflection.
"You."
To Kelly's baleful glare, Catherine Schade registered only a knowing smirk of delight. The hexenbiest had waited long for this moment. Tales of this Grimm's terror campaign against her kind had echoed in the wesen community for her entire life. Good, bad, a wesen's manner and circumstances didn't matter to this woman, such was her disdain. Knowing that she could expect a visit one day, Catherine took great pains to prepare - and finally, on this day, her hard work paid off.
"Yes, me," Catherine said. "How do you like my zaubertrank? I made it just for you."
A hasty backward kick from her captive almost reached her, if she hadn't the foresight to step back. A frustrated growl from Kelly brought a wider smile.
"Undo it," Kelly commanded. "Now."
"Oh, I'm terribly sorry, but I'm afraid I can't. This concoction is very special. A touch of Verfluchte Zwillingsschwester, a dash of Elwetritsch... oh, and I think there's some Seelendichtungsmittel for good measure."
Kelly paled, and not only from her blood pumping harder toward her tits. The Elwetritsch alone gave her pause. That particular bird-based wesen became most famous for its generous rack, big lips and other traits designed first and foremost for sex. Many humans returned from hunting parties for the wesen empty-handed, declaring their whole night a prank despite their lightened balls. Seelendichtungsmittel took the fears of how this drug might change her body and brought another layer of horror at the prospect of turning into this witch's puppet. She had to escape, now, before-
"Ohhhhh!" she moaned. A sudden pulse a pleasure slammed her sex. Something churned within. Sensations she thought long extinguished now bubbled to the surface, wetting her loins, as her lower half transformed. A widening backside split her black pants, revealing her sopping cunt in all its hairy uncovered glory. At her age, Kelly had foregone any notion of grooming her nethers for a potential mate. She had one duty, one will in life, to carry out her calling as a Grimm with no room for such pleasantries. Still, her needs lingered below her cold front, and this spurring on of those urges through a nasty zaubertrank brought them roaring out with a vengeance.
"Oh, I forgot," Catherine said. "I added some Koschie in there too. You never can tell what might happen when you mix two wesen in a verfluchte, but you're eager to be my guinea pig in this little experiment, aren't you?"
The hexenbiest's cackle cut to the core of Kelly's very soul. Where an Elwetritsch changed her form, the Koschie went deeper. They had libidos. Raging, large, demanding libidos that never found true fulfillment. They drank, they fucked, only stopping between spurts to heal humans of their injuries and afflictions. Often only so they could take their sex games into overtime. It already had a pronounced effect on her, lust running down her thighs as her pussy thickened and reddened into a ready and wanting hole.
"When I get free... nnngh when I get free..."
SMACK! A firm, hard hand to Kelly's ass brought her threats from their usual fierce and biting tone into a weak, mewling gasp. Her bubbly butt flopped from the force, jiggling about in ways that got her wagging it on pure instinct for someone to stuff it. Her whole bottom burned with carnal need. Every flinch and quiver announced their intentions to get their owner, the illustrious Kelly Burkhardt, some overdue dick inside her.
She couldn't take it anymore. The teasing, her nerves firing on all cylinders, every touch from torn fabric to the very air dancing on her skin, it excited her too much to resist anymore. She reached forward, strained over the counter and barely - just barely - latched onto her horny nipples.
"Oooooohh my god. Oh my god this feels so fucking good. Oh god."
She couldn't help herself. Driven almost with wills of their own, her fingers pinched her tender tips as hard as they could, pouring every ounce of Grimm strength into blowing her mind.
Throughout Kelly's ordeal, Catherine stood back and admired her creation. Every scar, every wrinkle, every muscle in the Grimm had transformed from an intimidating picture of power and skill into a perverse parody rendering those same details into punchlines of a wicked joke. Expansion had distorted all but the creases and cuts on Kelly's face. Truth be told, it revved her own engines to witness this shameful downfall firsthand. No longer satisfied with simply watching, she grabbed one of the few intact bottles and sidled up to Kelly. Her own breasts pressed against the Grimm through a blue chemise. The bottle tip aligned to Kelly's lower lips, rimming them, drawing out a delightful shiver. Leaning forward, through those curly locks, Catherine brought her mouth next to Kelly's ear and whispered her cruelest taunt.
"Aw, poor little Grimm," she said, lacing her words with the softness of feigned sympathy. "Is your slutty bimbo body begging for sex? Don't worry, I'll fix you right up."
The indignity grated on Kelly, but... she had no power. Her arms occupied themselves with kneading and squeezing and rubbing an orgasm out of her massive jugs. Her legs quaked from glass teasing around her hungry hole. The touch, the feel of lust left her brain fuzzier than her bush and pits, holdovers from before her inelegant changes. They signaled a maturity that belied her new hypersex persona, matching her head in texture and style. Each strand from all three parts wafted with a sex stench mingling Elwetritsch fragrance with Koschie potence to give her the unmistakable aura of a beast in heat. Its distinctly Kelly Burkhardt scent oozed from her pores with a sheen of sweat forming across her whole body.
"Open wide," Catherine cooed.
With her newfound yearnings, the moment that bottle rammed into her cunt was the greatest moment in Kelly Burkhardt's entire life. Her marriage to Reed? Her son's birth? Taking down her first wesen? All paled in comparison to that cool, thick, firm shaft driven into her depths as far as it could go. She wailed like a banshee when it entered, orgasming for the first time in that exact split second. She gushed freely, squirting into the bottle. Her breath quickened. Heart pounding. Arms and legs shaking. Her pained yet slaked expression lasted very briefly, wrinkling between her eyes, stretching her creases, huffing hot air through her nostrils while patches of pink and red from lust and rage rose across her cheeks and chest.
"I'll make you pay for this humiliation, witch," Kelly growled between clenched teeth.
"Is that so? Well, I guess I'll have to make the most of our time together, won't I?"
As much as she enjoyed this foray into the degrading for her Grimm sex captive, Catherine had another motive for her choice of dildo. Ramming it in and out, rubbing the woman's tit, she took breaks amid the pounding to read her measurements. Half an ounce. One and a half. Two. Three. The rising tide of a Grimm's sexual leavings brought with it so many new zaubertranks she could concoct. Some useful, some fun, all new territory for a hexenbiest. She could make a fortune from one drop alone, or spend it all exploring its properties and applications on unsuspecting subjects. And of course, on Kelly herself.
But, sadly, all things came to an end. Figuratively, literally, everything in between.
"Police!" a voice shouted from the front door.
"Looks like our fun is over."
Removing the bottle brought a pained wail from her victim. Seizing the chance, Catherine shoved her stained fingers in the Kelly's mouth and cleaned them on the Grimm's tongue - with a couple stray pubes for good measure. She expected Kelly to spit and rage at her for it, yet as she stepped away, she had the distinct pleasure of watching her swallow and lick her lips for what faint traces remained.
"My, I guess I have turned you into quite the slut. With that attitude, I'm sure you'll make a great prison bitch."
The officers entered and quickly recoiled. First from the bizarre sight, then from her stench.
"What the fuck is this!?"
"I don't know myself," Catherine lied. "I found the harlot like this when I got home. You might want to search her for drugs when you get back to the station."
"Don't tell us how to do our job, ma'am," the officer said, before turning his attention to Kelly. "Hands behind your head."
She took to the command swiftly, exposing her wild armpit hair through freshly made tears. The act instantly flooded Catherine's kitchen with her yearning smell, seeping into everything it could while the offended officers cuffed her wrists and walked her out the door.
As they left, Catherine took a long deep whiff and savored this victory. She almost didn't mind hearing Kelly's new tits smacking into everything on the way out, or the trail she left on her once pristine floor. After all, the prize in her hands more than made up for it. Attaching a label, she wrote its contents on the bottle and set it atop a rack with the rest of her ingredients. Her latest trophy among many.
