Rrat Pranks

"Fuck, not again!" Mori yelled from inside the bathroom. She hopped off the toilet, but the damage was done. Her ass had been swamped in the overflowing toilet. Bits of turds and urine flowed up from the pipes, splashing Mori in both her own waste, and whoever else used it recently. Her dress was ruined.
Mori stormed out and loudly complained. "Looks like we need to get another plumber."
Everyone groaned. Fauna, who had been patiently waiting her turn was squirming, let out a whine. "Uuuuuuuu..." Her legs danced with frustration. "Who did this...?"
The other girls all crowded around, which made Mori get embarrassed. "Look it wasn't my fault!" She said, defensively.
"We know, we know." Kiara said, consolingly. "But we have to catch this criminal! Ame? Do you think you can figure this out."
Fauna's legs were dancing now, she was holding her legs together, clenching tight. Her bladder was small, she knew she couldn't hold out much longer. "Wait! Oh no..."
Everyone turned towards the Kirin reflexively. A few drops of piss, then a waterfall began to stream from between her legs. She hid her face in shame as her piss hit the floor in front of everyone.
An awkward silence.
Amelia helpfully cleared her throat.
"Actually, I did do a bit of investigation." She walked into the bathroom and stepped back out holding a very small camera. "I filmed everyone's actions in here after the last two incidents. I already had a pretty good idea of who it was, but I wanted to confirm my suspicions."
She rolled back the footage for everyone to see. Sure enough, just before Mori had gone in, there was Bae, armed with a set of tools.
"Wait no! That wasn't me! This is... That was Kiara, she can shapeshift, and we all know how much she likes poop!" Bae said, panicking.
"Accusing Kiara? Well, all we have to do is see if she has an alibi, right?" Ame said, confidently. "Do you?"
"Bae you little shit! I was reading superchats at the time. Here!" Kiara pulled up her channel, but everyone else was nodding their heads - that alibi checked out.
"So, any more deflections?"
"I... you... Maybe it was... maybe it was you, Watson, who brought in an alternate timeline version of me!"
"Accusing the detective, now that's a bold strategy. Kronii?" Ame turned to the Warden of Time.
"Yeah, I don't see any recent temporal disturbances. Why don't you just fess up?"
"Nah, I think we gave her a chance to come clean." Mori said. "Now it's time for the punishment."
All the girls surrounded the rat with angry expressions.
"The punishment should fit the crime." Fauna said, icily. "She has to be our replacement toilet."
"W-what?" Bae said, as the girls drew closer.
"That works for me." Mori rolled up her sleeves.
Bae turned to retreat, but Ame blocked her exit. Vines crept in and coiled around her leg. Kronii summoned her chains.

---

Bae was completely chained up in bondage, her mouth propped open, kneeling on the floor. Her first visitor was Kronii.
Kronii pulled up her skirt, presenting her pussy near Bae's mouth. The rat struggled and groaned. The warden's pussy was very clean. Kronii's face made a face of relaxation as the piss arced in a perfect curve into the rat's open mouth. The warm, mostly clear piss of the warden was actually mild, but piss is piss. Bae swallowed it down reluctantly. Kronii made sure to wipe Bae's mouth clean, as she didn't want her toilet seat getting too dirty. "I'm gonna have spicy noodles later, so I hope you're ready for that."
Her next visitor was Kiara.
"So, your first instinct was to blame it all on me, huh?" Kiara said in a surly voice. "Well, apparently I like poop, that's what you think, right? Well, I think you're about to find out whether you do."
Kiara plopped her massive ass directly onto Baelz's face. Kiara's trash compactor ass was quite powerful, and Bae's neck struggled under its weight. Fortunately, Kiara's hole was also clean. Kiara made a slight grunt, and a preliminary fart blew right into Bae's mouth. The taste of the air was already quite foul, Kiara's regular diet of lasagna and pizza was made quite apparent. A modest rod emerged out of the phoenix's large ass, pushing its way into the rat's face. Bae whined as the solid turd filled her mouth. The faint taste of cheese gave her an idea of what Kiara had earlier. Kiara sighed with pleasure. She reached for a piece of toilet paper, then decided it would be too tricky to dispose of and wiped it on Bae's hair instead.
"Don't forget to flush!" Kiara giggled as Bae slowly chewed up the solid turd, feeling every bit of Kiara's meal on her tongue as she forced herself to gulp it down.
Ina was next. "You're really quite flush with trouble, aren't you? One might say you're in deep doodoo."
Ina sat on Bae's face. Her ass had not been properly wiped, and her bush was much stinkier than the two girls who came before. A blast of an absolutely foul ramen noodle farts hit Bae in the face.
"Look at that, you've caught wind of what's coming next!"
Following up Ina's pun came a messy, stringy set of shits, as well as accompanying farts in between each one. Bae's mouth was filled with smaller, already broken up turds.
"Maybe you should try not to piss people off, hm?"
Ina turned around and pressed her unwashed cunt into Bae's face, which was streaming with tears from the stench of her nethers. Piss messily emerged from Ina's bush and, while much of it landed in her open mouth, her face and chest were also covered in dribbles of piss from the messy tako.
"Ahhh, well, I gotta go. See ya later!"
Ina left, without wiping, but she did at least wash her hands.
Right after Ina came IRyS. "Look what you've gotten yourself into this time." IRyS giggled. "Thanks for not selling out my involvement. Not that it wouldn't have gotten you anywhere." She whispered. "Still, I'll go elsewhere. Have fun~!"
The next few girls came in over the next few hours - Gura, who smelled awful for some reason, teased her for a short while before doing her business. Mumei, who didn't say much, but it was clear that she enjoyed every moment of it. Sana just made conversation with Bae without even addressing the sorry state she was in. Ame also didn't say anything, she just treated Bae as if she was a toilet without even a change in her facial expression.
Then Fauna came in.
"Are you enjoying yourself?" The rat was in an absolutely ruined state at that moment and shook her head. "Good. Time for your next meal."
Fauna hovered over Bae's restrained face. She strained, and Bae was able to see her asshole dilate a surprisingly large amount as a large rod of filth began to protrude out of it.
"I'm not going to make this easy for you." Fauna whispered. "You're going to have to work extra hard this time."
Fauna's massive stool hung out of her ass, dangling over Bae's face.
"Here it comes~." Fauna said, in her sweetest ASMR voice.
The shit fell out, plopping right onto Bae's face, landing on her nose and forehead, with only a small bit even touching her mouth.
"Now eat it. Pull it into your mouth with your tongue." Fauna commanded, quietly.
Bae's tongue reached pathetically for the stool, just barely in its reach. She stroked it, gently guiding it towards her mouth. Fauna's hand reached down to Bae's clit and started to massage it as she leaned in close to Bae's ear.
"I'm going to make you cum to swallowing my poop." She whispered.
Bae squirmed with discomfort and pleasure as Fauna played with her. She slowly pulled the log into her mouth. She couldn't help but moan with pleasure as she wrapped her lips around Fauna's log.
"Yes, that's it. This is your purpose, you filthy toilet."
Bae started leaking. Fauna began to softly guide her through the process of taking the shit further into her mouth, as it dragged along her face and nose, leaving a filthy trail. Inch by inch, she took it into her mouth, until the remainder outside was standing up tall, as a tower.
"Now chew it. Savor it." Fauna commanded, as she pinched her clit.
Bae shivered. She slowly began to chew it up, letting the stool grace her toilet of a mouth.
"Swish it around. Make sure it gets everywhere."
Bae obeyed.
"Are you close yet?" Fauna said, as she worked the rat's pussy.
Bae nodded. The foul taste and the relentless pleasure were sending fireworks in her brain as Fauna's breathy voice sent chills down her spine.
"Swallow, toilet."
Bae swallowed in ecstasy as she went over the edge, cumming and wetting Fauna's hand with her piss.
"I'm filthy. Clean me." Fauna commanded, as she presented her asshole for Bae. Bae licked her ass, circling it, gathering all the residue off. She stuck her tongue inside, over and over until there was nothing left to clean.
Fauna leaned in to Bae's ear for one last message. "You'd better get used to this, because we're going to be doing this every time I come back in here. Is that clear?"
Bae nodded.
