It wasn't often that Kim would get out of work early, but the cafe closed early in order to dodge the throngs of Halloween trick or treaters that would be out and about. The sun was starting to set, and with Halloween night wide open, Kim was already on the phone with Leila to make some Halloween plans.

"Heyyyy, work let me run out a little early!" Kim said, smiling brightly. "You wanna watch some Halloween movies when you get home?"

"Ooh, that sounds delightful! Let's do the one with the talking dog exploring the haunted mansion!" Leila replied over the phone. It was convenient that Kim was able to hide a grimace at this response; maybe one day she could bully Leila into a real horror movie, instead of the "spooky" stuff made for kids.

"Yeeeeeah, alright... sounds good. How long d'ya think you'll be?" Kim stuck to the sidewalk, her bat-wings folded behind her, a spaded tail wagging behind her.

"I need to accept an order for fabric, and the driver's running a little behind..." Leila admitted with a sigh. "So I might be running late."

"Awww," Kim frowned. "I'll get a head start on dinner then, and then we can... can... uh..."

Kim paused, feeling a chill run through her. She glanced behind her, but she didn't see anybody or anything in particular. Her eyebrows furrowed.

"Kim?" Leila called. "Is everything okay? You went quiet."

"Um... o-oh, sorry, just... spaced out a bit." Kim came up with a quick white lie. "I'll catch up with you tonight, okay hun?"

"Okay! It's gonna be chilly tonight... can't wait to snuggle up with you~" Leila giggled.

"Need a warm body? I'm your girl!~" Kim snorted, getting a cheap laugh out. "Ohokay Leila, talk to you later, hehe~" Kim smiled, chuckling as she hung up the phone. She snuck another glance over her shoulder—she had a hunch that someone was watching her...

Still didn't see anyone. She continued on her way, across a four-way intersection. Kim's suspicions weren't unfounded as, when Kim turned the corner, a ghostly figure poked their head out from a nearby alley. She had long wispy hair growing down to her hour-glass waist that billowed as if being suspended in water; the hair was a pale shade of white that matched her cadaverous pallor.

"A warm body, you say..." She hissed with delight, her cheeks stretched in a toothy smile. "It's free real estate... ihihihi~"

The woman cackled, her entire body rising from the ground on its own. Where her legs should've been funneled into a narrow appendage resembling a tail... it was translucent and flowed like concentrated fog, waving like a mermaid's tail. She soared over the buildings and tailed Kim silently from a distance, drawn by the warmth of her body...

Kim let down her guard well enough once she was back in her own familiar neighbourhood, and it wasn't long until she was approaching her apartment complex. Leila and Kim shared an apartment on the third floor. She peered through the front window to confirm if the elevator was still busted...

"Yyyup, still fixing it." She pouted. "Better take the long way."

Her bat wings unfurled, stretching to their full wingspan of ten feet. She performed a couple stretches to limber up, before taking off from the ground, flying up to the third floor. She drifted around the building, towards the rooftop. There was a door at the top with a stairwell leading to the third floor... she timed it and, yeah, it was quicker. And Kim didn't get many opportunities to stretch her wings.

Tucking them back in, she descended the metal stairwell to the third floor high, and then it was a skip and a hop to her apartment. With the key in hand, she unlocked the door and let herself in.

"Haaaah... busy day." She stretched her arms towards the ceiling. "I guess I got some time... maybe I'll do spaghetti and meatballs tonight. Really big meatballs, Leila likes swallowing them whole, hehe."

Her tail swished behind her as she passed the window, making a beeline for the fridge. She did a quick check for ingredients.

"Garlic and onion, good. Pack of beef too, good." Kim nodded, closing the fridge. "Let's check the pantry..."

As Kim turned her back to the window, she missed the appearance of a grinning spectre at her window, a pale woman whose visage seemed to shimmer against the bright light of the full moon. With a grin so wide that her face seemed like it would tear in half, she reached a ghostly hand forward, reaching through the window frame and phasing through the glass as if nothing was there...

Kim hummed to herself as the ghostly apparition stalked her from behind, a wispy tail following her, stretching across the room.

"Hmm... yeah, got a box of spaghetti right there, good." Kim closed the door. "I guess I'll take it easy until..."

She paused. There was that ominous chill again, like she was being watched. Like there was someone else inside the apartment with her. But that couldn't be right, the door was locked when she got here, and Leila wasn't going to be home for another hour. She straightened up, getting ready to glance around the room.

But before she could lay eyes upon the ghostly figure invading her room, the apparition swivvelled behind her, a translucent hand reaching for the side of her head. She pointed her index finger, drawing it closer to Kim's ear...

"Shshshshsh... be still..." The ghostly women whispered with a coddling lisp.

Kim felt an icy sensation grip her ear as, unseen to her, a cloud of wispy fog began to slip into her ear canal; the ghostly woman's finger evaporated into mist, entering Kim's head. Kim's body froze up, her eyes turning glassy and dull. It was like experiencing sleep paralysis, only she was standing in the middle of the kitchen, and she was very much awake. Her body wouldn't respond to her commands, almost as if her limbs were frozen to her sides...

"Aaah... what a supple, warm body..." The ghostly woman fawned over Kim, stirring her finger; it swished around inside of the bat-winged girl's head, jumbling up her thoughts in the process. Kim's eye twitched involuntarily, her breath heavy. As the ghostly woman drifted closer, she licked her pale lips with a serpentine tongue.

"My name is Cynthia... do you like it? It's an elegant name... one you'll be getting used to before too long~" Cynthia chuckled, pressing a finger against Kim's chin. "Won't you lower your defences a little and... let me in?~"

Though Kim's mind strongly objected to the idea, her body moved on its own; her lips parted slowly, opening wide. Cynthia chuckled, clasping her hands together.

"Perfect. Now hold still...~"

Cynthia reached inside of Kim with both arms; they dissolved into a cloud vapor, flowing towards Kim. Cynthia dissipated into a cloud all around Kim, drifting towards Kim's exposed skin. The vapor slipped in anywhere it could; though her mouth, inhaled through her nostrils, even slipping through the pores on her skin and legs.

Kim's body tingled all over as the last of the vapour penetrated her, a wispy ghost tail whipping into her mouth. She swallowed reflexively, her body relaxing, as if someone flipped a switch to reactivate her.

What's your name? A voice called out in her head. It wasn't her own.

"My name is Kim!" Kim responded instinctively, her eyebrows furrowing as she clutched her skull. "Get out of my head!"

Oh? That doesn't sound right. Say it again!

"My name is Cyn... it's Kim! It's Kim, it's... K..."

The more that Kim thought about it, the less sure she was. Her mind was sending her mixed signals; she leaned against the counter top, her body pulled in two different directions.

Why not Cynthia? It's a much prettier name~ The voice in her head insisted.

"N-no, that's not... it's... Cynthia...?" Kim muttered to herself. The voice in her head was right, it was a pretty name. It felt amazing to say it out loud; it sent waves of pleasure surging through her entire body. She moaned, pressing her thighs together as she tried to stifle her reaction.

"Cynthia... Cynthia..." Kim said it over and over again, her lower body quavering.

Are you ready, Cynthia? To open yourself up, and give yourself wholly to me? To us...

"Yes... I'm Cynthia..." The bat-winged girl chucked to herself, her dull eyes squinting, resonating with the ghost's sympathetic vibrations. It was nice to be Cynthia. She couldn't imagine a a time where she was anyone else, as the ghostly fog in her brain stirred something within her... suppressing everything that ever made her Kim.

Strip for us. Make us whole, Cynthia... As the voice insisted, the body obeyed, as she began to undress herself down, revealing herself bare. She paced towards a mirror, admiring herself.

Her body surged with pleasure. She lowered two fingers towards her quivering labia, massaging the other walls. Her body was so sensitive; she felt her lower body opening up to the slightest touch. It was the sensation of two souls in one body, the entanglement of touching another body, and being touched. Their souls hadn't fully overlapped, the possession hadn't taken hold, but with every sensuous touch of her flushed body, the divide between new and old Cynthia grew blurrier and blurrier...

"AH!~~"

Alone in the apartment, a woman cried out, collapsing to the sofa; the mirror glistened with the silvery ejaculate her body had burst with. Her body was so soft, so sensuous... it would be the perfect vessel.

"Finally... she let go. This body's mine~" Cynthia chuckled drunkenly, cupping her new hands under her new breasts. The spirit had successfully spirited Kim's warm, supple body away from her, and now she could make it her own.

She kicked her legs upwards, rolling back onto her feet. Her eyes sparkled with a new intelligence behind them, her irises shifting to a mesmerizing shade of stark red.

She paced to the mirror, examining her new body.

"Well, everything appears to be in the right place... but this woman was so skinny and plain, it's like looking at a skeleton. I think I can make some improvements~" Cynthia chuckled, licking her lips; their pink colour deepened to a luscious red, swelling slightly.

She rubbed her hands down the sides of her legs, manicured fingernails shimmering new red colours; her thighs wobbled and pulsated, puffing out into a more shapely form. She massaged her bottom, allowing her hips and ass to grow at just the slightest touch, granting herself an hourglass figure that any man or woman would die for.

She splayed her fingers across her breasts. They were tiny things, little mosquito bites, but she would fix those right up. She rubbed her palms across the tender flesh, warming up her skin in the process; tingling energy coursed through her body, settling in her chest. She swooned as she felt her buxom bubble from within like a soda drink, rippling with energy as they swelled in gentle undulations before her eyes. With every beat of her quickening heart, her breasts grew faster and faster, their curvature appearing in the corner of her eyes.

From B-cups, to C-cups, D-cups, and well beyond, Cynthia wouldn't stop coaxing her breasts to grow. She missed the sensation of blood coursing through her veins, the adrenaline of yielding a body so utterly under her control, the coursing of dark magic intermingling with her new, supple, youthful skin. Every second that past, she could feel herself become more radiant, more beautiful. The room shrunk around her as her legs gained more definition, greater stature, as she gained another foot in height...

She cupped her voluptuous breasts in her hands, admiring her handiwork. They had grow, sticking out from her chest, perky, perfectly round, voluminous things, the size of pumpkins. She brushed her fingers against the erect nipples, sticking out like thumbs, moaning at their sensitivity. She rubbed her thighs together, lipping her lips with a serpentine tongue stretching over a foot long that snaked around her chest.

Cynthia was settling into her new body well, upgrading this mild-mannered demon girl's body into something befitting a supermodel... or a porn star. She moaned, getting horny at the sight of herself, her short-cut hair spilling down her back in long streaks. She could feel herself getting wet and sticky at the thought of her beautiful, perfect, hot body...

...She retracted her hand to examine her fingers, and grimaced at the gooey, glowing green strands of ooze that coated her fingers. Ectoplasm. An unsightly reminder of her undead condition.

"Ugh." Cynthia reached for a towel and wiped herself off. She'd have to get ready, in case someone else showed up...

"Kim, I'm home!~" A woman called out from the other side of the door. Cynthia snapped to attention, hearing the door unlocking. Leila the lamia would slither in, a cloth bag in hand. "I picked up some snacks from the... huh?"

Leila paused, gawking at Kim's naked... oversexed body. It was hard to look away.

"...Uh... why don't you close the door behind you." Cynthia asked Leila, trying to act casual, speaking in Kim's voice.

"U-um... okay." Leila complied, the tip of her scaled tail shifting to close the door behind her. "Is dinner ready yet? I'm famished..."

"Oh, well... I was thinking that I could be your main course~" Cynthia chuckled, fluttering her batwings to close the gap on Leila.

"K-Kim!?" Leila stammered as "Kim" threw herself overtop of her, her pronounce chest fighting for space against Leila's.

"I like you better when you're naked." Kim purred, her hands lowering to unbutton Leila's blouse. Leila struggled, trying to break free.

"K-Kim, you're hurting me," Leila whimpered. "Th-this is really strange, I-I didn't think it'd be this kind of night, I- ah!"

Leila cried out as "Kim's" sharp nails dug into her bra, her fingers pressing into Leila's pronounced chest.

"Yessss... incredible..." Cynthia hissed. "Naturally perfect..."

"K-KIM! I don't like this!" Leila insisted. "P-please, calm down-"

"Stop calling me that!" Cynthia snapped, her eyes narrowing.

"DON'T SHOUT AT ME!!" Leila shouted, raising her palms to push "Kim" to the floor. "WHAT'S THE MATTER WITH YOU!? WHEN I SAY NO, IT MEANS NO!"

Leila's slit eyes narrowed as she reared up over Kim, getting ready to give her a firm talking to, but Kim's body rippled strangely on the floor, her body glistening with a strange substance. Her breasts and pussy seemed to leak an eerie, glowing, fluid... and Kim was glaring at Leila with an annoy set of glowing red eyes.

Leila gawked, and then gasped.

"You're not Kim!!" Leila blurted out, covering her mouth. "A-are you??"

"Dumb bitch catches on quick..." Cynthia grinned. "Name's Cynthia. And I plan on moving into your little side toy's body, permanently~"

"You'll do no such thing if I have anything to say about it!" Leila glared at the stranger taking her girlfriend's name and body; her massive serpentine tail lashed forward, knocking aside some furniture as she quickly wrapped up Cynthia in her scales.

"Gngh!" Cynthia grunted as Leila put the squeeze on her. Her expression curled into a wicked grin. "Haha... are you going to hurt me? Torture me until I leave? Whatever you do to me, hurts your sweet little fucktoy too!~"

"I don't need to use force to get what I want..." Leila muttered. She closed her eyes, focused internal, and then slowly opened them. "You're going to do what I tell you."

"Hah! That's a likely... story...?"

She gawked, looking into Leila's beautiful, hypnotic shimmering eyes. They pulsated with flashing colours, purple, blue, red, in entrancing sequences. Cynthia was helpless the moment she laid Kim's eyes on them; soon, the world ebbed away as her attention locked onto Leila's eyes, her own expression blanking out. A drop of ectoplasm crept out from her slack-jawed mouth like drool...

"You are under my command..." Leila lowered her voice, the flashing of her eyes intensified, overwhelming Cynthia's mind.

"I am... under your command..." Cynthia muttered robotically.

"On my command, you will release Kim from your control..." Leila's tail tightened possessively around Kim's slack body. "And you will leave this place, and never return..."

"Yes, my mistress..." Cynthia responded, nodding slowly.

"And you will never possess another living soul ever again. For every time you do, you will think of me..." Leila smirked. "And you will feel overwhelming shame."

"The most shame..." Cynthia slurred. Leila hauled Kim's body along like a doll, reaching to open the window wide.

"Now! I command you to leave this place!" Leila bellowed.

Fwoosh! Kim's head lolled back, her jaw opening wide as a wispy fog escaped her lips, the spirit of Cynthia leaving her body. It flowed to the window, escaping through like a draft. Leila watched with a scowl as the ghost departed their premise...

Leila slammed the window shut, locking it forcefully. She cradled Kim in her arms.

"Kim...?" Leila patted Kim's cheek, trying to coax her awake.

"Ugh... my head..." Kim muttered. "The lights are way too bright... Leila, could you-"

"KIM! You're back!!" Leila hugged Kim tight, bouncing up and down. Kim writhed in Leila's powerful grip, as well as the painful sensation of her overflowing buxom squishing against Leila's bust.

"AWAWAW, EASY, EASY! Jeez, mind your grip!" Kim protested. Leila, realizing her own strength, tenderly lowered Kim to the ground.

"H-how are you feeling?" Leila clutched her hands together. "Are you hurt? Are you dizzy? Do you need some water?"

"Fine, s'fine, just... whoa." Kim finally spotted her enormous chest, and her attention lowered to the rest of her voluptuous body... covered in ectoplasm. "Wh-what the hell is this goopy stuff!?"

"U-um... well I, um... there was a spirit possessing you but I shooed it away. But I think it... might've done some remodelling..."

"Remodelling is right! None of my clothes are gonna fit anymore! Heck, I think I'm bigger than you now!" Kim exclaimed, bouncing her breasts in her hands.

"I-I think you're... swelling with ectoplasm. Leftover from the possession." Leila grimaced. "It should leak out on its own, but... m-maybe I can..."

Leila's hands hovered around Kim's chest, her serpentines eyes drifting up to Kim; with a cursory nod of approval from Kim, Leila tensed her fingers, squeezing and massaging Kim's basketball-sized breasts.

"HACKGRURGLRFLEBLE!" Kim released a wet, garbled noise as ectoplasm shot up her throat and into her mouth. She spat up a load of it into the sink, her eye lids fluttering groggily. "Tastes gross... bleck..."

"O-okay, let's just... sweat it out for now." Leila smiled politely. "I'll get you some towels..."

It would be some time until Kim would shrink back to her more typical proportions. But it was fine; Leila did like to fawn over Kim...
