That Time Gelica Made a Mistake

Cass slid out of the elevator with a grunt. Her arms were loaded with over a dozen bags of food, each of which was nearly bursting with tasty treats for her upcoming feeding. She’d opted for a bunch more sweet goodies this time in celebration of Halloween. Her body sure wasn’t going to thank her for this, but her fans would eat it up - especially in the sexy little stereotypical devil outfit she’d gotten for the occasion. She could practically taste all those thirsty donos now…

Opening her front door was a challenge, but one that Cass eventually managed to win by using her tail to hold her bags. She let herself in and breathed a sigh of relief as she let all the bags drop onto the floor inside her apartment. She really needed to find a better way to do this than to lug so much stuff home every single week. She couldn’t really drive a car since… y’know… no feet. Maybe a cart? Were there public-use carts? She’d need to do some research on this.

Eh, regardless, that was a problem for later. Right now, she needed to get her cold groceries put away. There was nothing worse than having to void an entire feeding because of some rotten meat or veg. That was not only a huge blow to her savings but to that week’s stream payout.

Cass got to work putting all her food away. It was fast going since her fridge and cupboards were mostly bare save for the few things she kept around for whenever someone else came over - not that that happened often. Cass didn’t have many friends other than Margo and she refused to come over for some reason. Plus, Margo was a vamp, so she didn’t really eat anything. She mostly just drank blood, coffee, and sometimes a soda. A bland and boring diet if Cass ever saw one. Seriously, how did Margo stand only having, like, three things-

The lamia froze on her way to start putting away her non-cold junk. Her tongue flicked in and out of her mouth, tasting the air. Something was off. She didn’t recognize this scent. Someone had been in her kitchen- her nest. A low, high-pitched growl started to rise up her throat. This was HER territory! NO ONE was allowed in without her permission! She was gonna CRUSH whoever dared come in here!

The furious demi-human sank down low and started to slink around her own home, frequently tasting the air to track the intruder’s tracks. Nothing in her living room, so back to the kitchen. The scent went to her sink, then to the cupboard where… yup, her soda for Margo was drunk! HEATHEN! Out of the kitchen, the scent went to her bathroom. They’d been all over this room. Then to her studio, then… her bedroom.

Cass slithered into her bedroom, eyes piercing the darkened room. She had black-out drapes permanently tacked over her windows to give the room that perfectly safe den feeling that she craved, but that didn’t make it harder to look around the room at all. Between her decent night vision and excellent sense of smell, it was easy to take in the whole room at once - including the human-sized form laying on her bed. The. Fucking. NERVE! This invader was getting all their bones crushed, then getting arrested, then sued, then maybe crushed again! Vile creature! This was-

Wait. Right. Cass froze, her claws inches away from the human-like form. This smell… it wasn’t human. Honestly, Cass didn’t know what this thing was. Its scent wasn’t like anything she’d smelled before. Also, now that she was looking more closely, it… wasn’t wearing clothes. There hadn’t been any clothes on her way here, either. No clothes… strange scent… the nerve to invade a lamia’s den…

Ah, fuck it! Cass wasn’t one to be careful anyways and she was too pissed to start now! Since this thing wasn’t human or any type of demi-human that Cass could recognize, then screw it! EAT THE BITCH!

The hungry lamia moved down to where the thing’s feet were and, in one deft movement, unhinged her jaw and scooted across her bed. Its feet were in her throat before Cass started to feel movement and its hips were filling up her cheeks before it started to struggle. That’s right, it’s too late, heathen! Pay for your crime with your body, you-!

Suddenly, the creature’s body stopped entering Cass’ mouth. No, that wasn’t right - it kept going down her throat, but the upper half of the thing had… separated. Cass blinked in surprise as the rest of the creature seemed to bunch up before starting to run across the bed. Yes, run. It still had legs? HOW!? They were in Cass’ gut now- wait, that wasn’t the important thing! It had jumped off the bed! It getting away! CATCH IT!

Cass hissed murderously and surged off of the bed after the now much smaller creature. It scuttled into the hallway and Cass followed. It was in the light now, so Cass could finally get a good look at it in color. It was… It… Uh…

It was a tiny purple woman. A tiny, see-through purple woman with little bubbles inside of her. What the hell was that thing- GAH, she’d gotten distracted again! EAT THE BITCH!

Cass darted down the hallway after the small woman, not bothering to be careful in her pursuit. The little shit was so despite being so short! It slipped into her living room and Cass barely caught sight of its legs squeezing under the couch she’d inherited from one of her old roommates. Cass put a hand under the couch and threw it aside. The little monster was right there! She grabbed for it and- FUCK! It was so damn SLIPPERY! It squeaked out of her hand and scrambled into the kitchen. Oh, NO you DON’T! NOT CASS’ FOOD! BEAST!

The desperate chase went on for far longer than it should have. Cass was just too damn big to catch this tiny, slippery thing! It didn’t help that she wasn’t used to hunting live prey. Curse her urbanized lifestyle! She can’t even protect her den from one purple rat! SHIT!

The pursuit finally ended with the purple woman managing to put some space between herself and Cass, then seemingly disappearing. Bitch! Cass’ tongue was going mad trying to track the thing down, but the odors in the air were a garbled mess thanks to the extended chase. Then… she heard a door slam in the hall.

Cass slid into the hallway, slamming hard into the wall in her haste, and scanned the doors. The bathroom! She darted for it, grabbed the handle, and… it was locked. How had that little bastard locked the door!? The pissed lamia yanked on the handle, then yanked again. Harder and harder, until-

*SNAP*

The door handle came off in her hand.

…

“FUCK!”

Cass tossed the handle aside. Her vision was going red. She needed this miserable little beast OUT! OUT OF HER NEST! She slammed into the door. Despite her bulk, Cass couldn’t get a good run-up at the door because of the narrow hallway. She slammed into it again anyways, then again. She was about to start again when, through her rage-induced haze, she noticed a loud, constant pounding on her front door.

The lamia didn’t know what business someone had with her to knock like that but now was NOT the time. She slithered over to her front door, yanked it open, and hissed, “WHAT!?”

On the other side of the door was a remarkably average-looking woman. She had a nice face and colorful hair, but that was about it. Cass would normally be more generous with her attitude toward people, but right now, she was a little bit busy.

Upon Cass’ heated greeting, the woman jumped a few feet back and swallowed. She looked Cass fully up and down, then seemed to steel herself. Steadfastly avoiding Cass’ eyes, she said in a shaky but firm voice, “My roommate seems to have wandered off without permission. I heard some disturbances while looking for her and was wondering if she found her way into your apartment.”

Cass’ eyes glittered maliciously. “So this little purple intruder is yours? HUH? This whole thing is YOUR fault!? HUH!?”

The blindingly blonde woman flinched. Still, she spoke clearly when she responded, “Miss, please calm down. I know you’re worked up right now because someone has invaded your territory, but being violent will only cause problems.”

“You know that telling a pissed-off person to calm down NEVER works, don’t you!?”

“I’m not telling you to do anything, miss. It’s a request. I just want to get everyone through this without needing to go through social services.”

It was Cass’ turn to flinch. That certainly cooled her off quickly. If there was one thing that a big, predatory species like a lamia wanted to avoid, it was an encounter with Demi Social Services. Those people had NO patience for demis like her. Cass bit her lip. Then she tensely coiled up her lower body beneath her and clutched her arms in front of her chest. “...F-Fine. Just… don’t call them. I can’t afford a write-up, ok?”

The woman seemed to visibly melt. She sighed and gave Cass a small smile, finally looking her in the eyes. “No problem. So, uh… I take it that Gelica really is in your apartment then?”

“Gelica? Is that the little thing’s name?” Cass seethed. “Weird name. But yeah, that’s probably the thing that just locked itself in my bathroom.”

The woman blinked. “Little? That doesn’t sound right. Gelica was about five-ten last I saw her…”

“Last you saw her? What does that mean?”

The woman ignored Cass’ question. She just bit her thumbnail and glanced up at Cass. Then her eyes flicked back down to her belly. She gasped. “You- You didn’t EAT her, did you!?”

“What!? Of course I-” Cass stopped. She looked down at herself. She had a decent-sized belly from the half of the purple lady she’d already eaten. It was actually an impressive little tum, but she’d just been too pissed to notice. Whoops. So much for being urbanized. “Uh… only a little bit? My instincts kinda took over for a while. She was still running around all over the place, so it’s fine, right?”

“For her, yes. But she might be poisonous! You might be in danger right now!”

It took Cass a moment to process that. Then she looked back down at the woman. “No, I’ll be fine. I’m a northern lamia. We’re resistant to most poisons.”

Despite Cass’ assurance, the woman still looked worried. “That might be so, but… keep a close eye on your health! If you start feeling woozy, weak, or nauseous at ALL, go to a demi-accepted physician immediately! If you can’t make it, then call me and I’ll get you the help you need!”

“Uh… I don’t have your number. I don’t even know who you are. Also, your, uh, ‘roommate’ is still in my bathroom.” Cass narrowed her eyes. “At least, she better be. If she’s snuck out and is wandering around my nest, I swear to Hecate I’m gonna-”

“Ah, hold on, hold on! I’ll get her out in just a second, so just be patient!” The woman hastily pulled out her wallet, fumbled with it for a moment, then pulled out a card and gave it to Cass. “My name and number! Now, where’s your bathroom? I’ll get Gelica home right away!”

“It’s this way, uh…” Cass glanced at the card. “Belle.”

Cass showed Belle the way to her bathroom. To Cass’ dismay, she heard her tub running behind the battered door. “Wha- What is she doing in there!? She BETTER not be flooding my bathroom!” She rounded on Belle, fury in her eyes. “Get your little purple bastard out of my bathroom NOW!”

Belle took a step back. “O-Ok, ok! Just don’t rip her head off when she comes out, ok? I mean, she’ll probably be fine even if you do, but… it’s the principle of the thing!”

What? Probably be fine? That wasn’t normal. Actually, now that Cass was thinking clearly, it was also weird that she’d been able to eat half of the purple lady without her dying - and where had those new legs come from? “Hey, what even is Gelica, anyways? I’ve never heard of a demi like her,” Cass asked.

“Oh, uh… that’s… classified,” Belle said uncertainly.

“Classified? What the hell does that-”

Belle interrupted Cass’ question by yelling out, “GELICA! I know you’re in there! If you want some of Bran’s homemade pudding tonight, you’d better get out here right now!”

Cass just stared at Belle. She was threatening this thing with pudding? What kind of threat was - oh, it worked. The water had turned off almost immediately. Then a massive *GA-LUNK* sounded out, followed by several heavy-sounding footsteps and a ton of sloshing. The door clicked unlocked, it swung open, and…

Holy SHIT, what the hell was THAT!? It wasn’t a tiny purple woman anymore. It was a purple woman roughly Cass’ current height. She looked smooth and glossy and… empty. She also had a gut that was wider than the gods-damned doorframe. Her stomach was MASSIVE! It looked tight as a drum, but as Cass watched, Gelica squeezed her flanks with her hands enough to fit her gut through the door. Cass and Belle both backed up to give the belly room in the hall. Then Gelica seemed to look at Cass warily. She didn’t even have pupils in her vacant eyes - how was Cass managing to get emotion out of this?

“Gelica, what is this?” Cass was broken out of Gelica’s soulless stare by Belle’s sharp words. The shorter woman had an eyebrow raised at Gelica. She slapped her gut, making it wobble and slosh violently. “I told you - keep your height shorter and keep yourself small enough to fit through doorways! Just look at you - you’re too bloated to fit through doors without physically squishing yourself! Also, why did you leave the apartment!? You KNOW you’re not allowed outside yet!”

The sudden scolding caught Cass off-guard, but it seemed to be effective on Gelica. The purple woman seemed to shrink - no, she did shrink. Her head slowly moved lower than Cass’ until she was just a few inches taller than Belle. As she did, though, her gut swelled out even more, filling up the hallway with turgid purple flesh. Belle’s face looked a bit red after watching this, but she just cleared her throat and continued, “And how does that help now? You’re even wider now! You can’t fit through doors at ALL now! I have half a mind to take away your game privileges for this!”

Again, Cass didn’t get the threat meant for children here, but it seemed to work. Gelica started to cry… no, that wasn’t right. Tears seemed to be moving down her cheeks, but they were just tiny droplets of purple liquid that quickly got absorbed by her skin once they reached her chin. This was SO freaky! It was almost as if her whole body was-

Cass froze. “Wait a second - is Gelica… a slime?”

Belle’s eyes widened. Bingo. The shorter woman frantically waved her hands at Cass and stammered, “N-No, not at all! She’s, uh- She’s- Uuuh- She’s a ghost! A really corporeal ghost that can’t speak!”

“Uh-huh. Right.” Cass gave Gelica another once-over. No wonder she hadn’t recognized the smell. Slimes rarely lived in cities and Cass was a city snake, so she’d never met one before. She’d also never heard of a humanoid slime before and Belle’s reaction was really suspicious, but… “Look, whatever the deal is here, I’m not gonna report it or anything. Like I said, the last thing I wanna do is get involved with the DSS.”

Belle stopped her stammering. She bit her lip and looked up at Cass. “R-Really? Even after all of the trouble Gelica caused? Your apartment is a mess…”

Cass’ brow twitched. “I never said I was gonna let you off free. I just said that I’m not gonna say anything about whatever this whole situation is.”

“Oh. Right. Yeah, that’s fair.”

Cass sighed and shook her head. Then she glanced back at Gelica. The slime woman was staring apprehensively at her again, her hands resting on the top of her engorged gut. Honestly, she just looked ridiculous with a belly that size. A giant, globular gut. A massive, wobbly… purple… grape-looking… easy-to swallow… tasty… mouthwatering…

The lamia swallowed. Hard. “Hey, y’know… I just thought of something that would make me forgive you two…”

Belle straightened up. “R-Really? What is it?”

Cass licked her lips. She leaned over Gelica and grinned wide. “Lemme eat her just a little bit… ok?”

“Wh-What!?” Belle started. She wrapped her arms around Gelica and pulled her away from Cass, making that giant, delicious gut bounce around enticingly. “You can’t do that! I won’t let you!”

“And why not?” Cass hissed sultrily. She glided after Belle and Gelica, eyes fixated on that gut. “I’m not asking for all of her. I don’t wanna kill her anymore. I just want a little taste. What’s wrong with that?”

“L-Like I said before, she might be poisonous!” Belle insisted while still dragging Gelica away. “Also, I don’t know how healthy it is for Gelica to lose so much of her gel and membrane! Also, it’s just not right!”

“Not right for humans, maybe. But…” They were out of the hallway. Cass quickly slid around Belle and Gelica to position herself between them and the door. She was almost drooling now. “We’re not human, are we? Me and her.” Cass’ eyes glittered darkly. “Besides… it’s her body. Let her make the decision. Though if you refuse…”

Belle gulped. “I-If we refuse…?”

Cass licked her lips. “You gotta pay for all the damage to my stuff plus all the food that got crushed while I was… ‘dealing’ with Gelica.”

“...Oh. Right. That, uh, makes sense.” Belle glanced around Cass’ apartment. “So, uh… there’s a hole in the wall there and there and there… the door is ruined… you’ll need a new couch… wow, that’s a lot of food… uuuuh…” Belle gulped. Sweat started to bead her neck. “D-Do you think the landlord will accept credit cards…?”

Before Cass had a chance to respond, Gelica pushed away from Belle. She wobble towards Cass, then opened her arms wide. Cass’ eyes sparkled. “Well, looks like she made a decision! For being something without a heart, I’d say she’s pretty thoughtful, isn’t she?”

“Gelica, you don’t have to do this- I-I’ll pay!” Belle insisted, “I will! It’ll just mean living off of ramen and water for a while! I got through college like that and I can do it again!”

Ok, Cass was kinda starting to feel a little guilty now. “Uh… look, I’m not the mafia or anything. I’m pissed about the whole ‘invading my nest’ thing, but you seem like nice people… or, well, you do.” Cass looked at Gelica. “Does she really not speak?”

“Uh… if she can, she hasn’t yet.”

“Right…” Cass rubbed the back of her neck. She continued, “I kinda got carried away again with wanting to eat your pet- uh, roommate, so… you can just pay me back over time or something. Like, at a rate that doesn’t break your bank.”

Belle blinked. “Really? Are you sure?”

Cass sighed. “Yeah, it’s fine. I’ve got your number now anyway, so we can-”

In the middle of Cass speaking, Gelica seemed to get angry. She moved her arms forward and they rapidly grew out - straight at Cass. They caught her in the mouth mid-sentence and forced her jaw apart. Then the slimy tendrils started forcing their way down her throat.

Cass, in her surprise, lost her balance for the very first time in her life and toppled over. The chains of ooze now working their way down her neck remained intact even after the fall. The lamia tried to grab the arms to get them out of her mouth, but she just couldn’t get a grip! She clawed at them, but no matter how many times she ripped out chunks of purple gunk, the goo limbs would just reform themselves before Cass could completely sever them.

“OOOF!” Cass breathed. She couldn’t breathe…! Weight… pressing… down…! Ugh, that fat-ass slime had gotten closer and had set her fat gut on top of Cass! Now she couldn’t even get back up! She was trapped!

“GELICA! What do you think you’re DOING!?” Cass heard Belle shout. The lamia had just the right angle to still be able to see the human woman storming up to Gelica. “What did I tell you about restraining people? You need to stop!”

Gelica didn’t stop. She shook her head and kept going, somehow managing to display determination on her blank face. Cass flinched as a tense spasm ran across her human gut. Oh gods, she was getting too full! She couldn’t move her arms to where she needed them either! Her human belly was gonna pop at this rate!

The dirty-blonde monstress tried in vain to get away again, but she just couldn’t get any grip with her tail while she was on her back like this! She twisted her tail around to try and grab the slime woman, but her giant, bloated gut was too big and in the way still. A heavy rumble ran through Cass’ belly and the snake woman shivered. Getting forcibly stuffed like this should NOT feel nearly as good as it did! It hurt and it was cold and she hated feeling pinned like this, but holy FUCK did getting unwillingly blown up like a damned balloon feel hot as hell! If Cass wasn’t worried that she was two seconds away from her top half exploding, she might even be able to enjoy this-

Ooooh, fuck! Cass groaned while Belle made things worse for everyone involved. She had run around them and was now desperately trying to shove Gelica’s massive water gut off of Cass while saying shakily, “Oh shit, oh God! I-I’m so sorry! I thought I had a good hold over her! She’s never done anything like this before! Oh no no no no no-!”

Belle’s good-natured attempts were only making Gelica’s water-bed belly slosh around, though. The sloshing gut kept pushing down on different parts of Cass’ gut as it shifted, constantly making Cass feel as if she were about to explode, be sick, and scream all at once.

Oh fuck, this was it! Tears dotted the corners of Cass’ eyes while her gut rumbled and spasmed. She was too full and she couldn’t push everything down! She looked down at herself and could just barely see her human belly poking up through the translucent flank of the slimy gut holding her down. Not just barely because of size but because of the thick purple hue - her gut was giant. It was potentially larger than any belly she’d ever had before. The difference is that she was still getting bigger and bigger even now.

Ooooh, too much! So much slime was inside of her! It was all too much! She was going to- oooh, she was gonna- pop- AAAAAAAH-!

*GLuuUUUUuurrrrr-OOooooorp*

A massive amount of gurgling accompanied Cass’ body going limp. The pressure was rapidly fading from her aching gut. Her stomach was deflating at an insane rate with the weight of Gelica’s belly pushing all of the slime down into her snake half. Normally, Cass had to get food to go into her snake belly either by waiting or forcing it down, but the valve separating her different stomachs must have given way to stop her from bursting. She was saved. She was exhausted and feeling warm and tingly all over, but otherwise… she was okay.

Without the threat of death close at hand, Cass had a chance to think. She glanced around. It wasn’t what she’d been intending, but technically… this was exactly what she’d asked for, isn’t it? She’d so wanted to slurp up enough of that slime to feel stuffed to the gills, and she had. Any more might threaten her feeding tomorrow, though, so-

Wait. Hold that thought. Now reverse it. This was exactly what she’d asked for. Cass looked at Gelica. The slime still had that determined look on her face. Was she… she was, wasn’t she…?

Cass looked over to Belle. The human was nearly in tears with her shoulder to Gelica’s gut. Cass rolled her eyes. Drama queen. She used her tail to tap on Belle’s shin. The woman looked down, then over to Cass. The lamia tried to speak, but… her mouth was full. Her arms were pinned, so no writing. Uuuh…

“A-Are you ok? Your stomach isn’t distended anymore - does that mean something ruptured? Am I too late? Oh God, why did this-”

Cass grunted in annoyance and smacked Belle’s leg with her tail. The wailing woman toppled over. At that, Gelica seemed to get agitated, and… stopped pumping slime into Cass! Her mouth was free! YES! She sucked in a deep breath, thankful for the fresh air (Gelica was SO lucky that lamia could hold their breath for hours at a time), and said quickly, “That’s enough! I’ve eaten enough! Belle’s off the hook, ok? Just lay off!”

A  bubble floated up through Gelica’s head. Then the slime woman’s agitation quickly turned to glee. She jumped up and down in her happiness… or, well, she tried to. Mostly, she just wobbled around a lot and put a lot of extra weight onto Cass (which she, for some reason, no longer seemed to mind). Meanwhile, Belle was sitting upright with a confused look on her face. “Wh-What… Why did she stop?”

“Who cares?” Was Cass’ response. A violent gurgle ran from the tip of her tail to her cheeks, where it burst out as a potent *Huuu-OOOooOOOOOORRRP*. “I’m just glad she didn’t pop me. It was kinda close for a second there…”

Belle sniffled. “Y-You’re ok, then? No ruptures?”

“I’m fine, woman. Jees, you’re a softie, aren’t you?” Cass grumbled. She belched again, then sighed contentedly. “Still… that wasn’t half bad. She doesn’t taste like much, but she’s sure as hell filling. I don’t think I’d mind having another taste again sometime.”

“Please don’t put that out there. You’ll make it come true,” Belle shivered. She stood up unsteadily and stared crossly at Gelica, who was still doing her little victory wobbles. “What do you have to say for yourself, huh? You just assaulted someone! Feel some shame! Also, get off of her!”

There was no shame to be had here, though. Only happy sloshing and jiggling. Cass also noted that the slime was perfectly soft porn rated, with a bare naked body but no nips or privates. Cass didn’t need to see those to appreciate the way those jelly-filled funbags were bouncing around on that gut of hers, though. For a slime, Gelica didn’t look half-bad. Hell, she probably had a better figure than most of the ladies Cass knew. Weird how life works, huh?

“Seriously, don’t worry about it,” Cass insisted. “I’m a big scary snake lady who ate half of her body earlier. She got her payback and also got you out of paying for my stuff.”

“But…”

“Seriously. It’s fine.”

Belle still looked worried, but she just sighed. “If you say so… I still feel like I should help pay for all this though…”

Cass thought for a moment. Then… she bared a wicked, toothy grin. “Well… if you really want to pay me back sometime… then…”

Belle’s eyes widened. She gulped. “Th-Then…?”

“Then… let me babysit Gelica whenever you’ve gotta leave her alone.”

“...What?” Belle asked blankly. “That’s not paying you back. That’s making you do more work.”

“No, see, it’s a win-win,” Cass assured her, though the saliva in her mouth was making it hard to sound smooth. She took a moment to swallow, then continued, “I can get her to do my cleaning and stuff for free, which’ll help me, and also help you by keeping her from wandering around to cause more problems.”

Also, it would let Cass fill her human gut to the breaking point again… and again… and again… all for absolutely free… Not that she’d say that. That’d be rude. And creepy. Heh.

“W-Well… uh… I guess that’s true…?” Belle responded, though she seemed conflicted.

“If you say no, then you can just pay for half of the damages. Oh, and my couch was custom-rigged to support my weight, so that’ll make replacing it cost more-”

The conflict was gone. “I’ll let you know in advance whenever I’m dropping her off!”

“Sounds good~,” Cass said a little too gleefully. She snickered to herself while Belle desperately tried to convince Gelica to stop dancing and start shifting her giant gut off of Cass. Her daily life was about to get a lot more enjoyable…

====================================================

Another fic for y'all! This one isn't Halloween-related, but I wanted to put it out anyways since I kinda need to get more out this month, heh.

I'm gonna be making an update post after this, so there's kinda not much to say here. Uhh... fun fact, the first character in this whole monster gal universe I've made wasn't Cass, but actually a succubus named Melody from an older fic called 'A Devilish Job'. She hasn't made a reappearance yet, but I'd like to have her back around at some point.
