Fatal Detention

Failing Class

“So, uh… Where were we?” The chubby yellow lizard asked, tapping the board with her pointer inquisitively. “I was talking about states of matter, and then chemical transitions, hm…”

A hand shot up from the front of the class. “Ms Alphys! I remember! You were talking about physical changes and chemical ones…” A deer girl responded, dressed in a preppy denim shirt and plaid blazer.

“Ah, yes! Thanks, Noelle!” Alphys went back to her ramblings, stuttering occasionally broken by passionate off-topic tangent. Most of the class had tuned her out already, holding their heads up with their hands as they struggled to even look like they were paying attention. The short teacher could barely reach the board, and her chicken-scratched notes were practically illegible.

“Hey, Kris. Watch this.” Alphys caught from the back of the room, a hushed laugh coming from the delinquent in the class. Susie was massive, double the size of Alphys, and her bulk intimidated almost everyone in the school. They had tried to punish her, but she would only get more ornery. Her human friend snickered with her, signing out something quickly that only exacerbated their giggles.

“I-Is there a problem… back there?” Their teacher demanded, authority not blending well into her sheepish tone. “I’m trying to teach!” She all but pleaded. Susie shot her a wide grin and smacked her hands together, faking rapt attention. That would be as good as it good, she realized, and Alphys kept talking.

She made it through the next few pages of notes before the giggles erupted again, and she locked eyes with Susie, who had a straw between her muzzle. There were only milliseconds between the eye contact and the wet slap of a spitball on her glasses. The back half of the class erupted into laughter, the only outliers being Berdly and Noelle, who both only glared at their classmates. Susie and Kris exchanged high fives as Alphys pushed down her irritation. She scraped the mushy paper off of her glasses, and removed them to wipe them clean.

“Nice shooting, Tex.” Susie taunted, in a gruff voice. “Fastest gun in the west!” She responded to herself, with Kris’ laughter only spurring her own. The purple dinosaur-girl cracked her knuckles. When she noticed Alphys’ face slowly becoming red with anger, her face evened out, and she punched her cohort on the shoulder.

“Not cool, Kris! I’ll have to punish your ass after class for being so bad.” Her human snorted as his face became red.

“You’re not going to punish anyone’s ass!” Alphys all but exploded, huffing and puffing as she jabbed a chewed fingernail towards the delinquent. This had the opposite effect- the whole class erupted into breathy laughter, save for the two honor students who slammed their head on the desk. “Ms. Toriel is not going to be happy with you guys!” Alphys warned them, but they paid her no mind.

“Teach, that old goat will just lecture us about ‘back in her day’ and send us on her way.” Susie mocked her. “Seems like a waste of all of our time.”

Alphys closed her eyes and tried to think of a way to get the class back on track. A loud crunch pierced the cacophony, and she snapped up.

Susie was giving her a shit eating grin, a piece of chalk between her teeth. A large yellow-green box of chalk sat on her desk. That had been locked away in the supply closet, how did she get into it?

Alphys grabbed the sides of her head. “I’m done!” She barked at them. “Noelle, Berdly, you can come with me and we’ll finish class. Ms. Toriel can deal with the rest of you. And Susie- you’re getting Detention!”

The class laughed in response, and Susie only reclined in her seat and continued chewing on the chalk, holding it like a cigar. She bumped her fist with Kris, who kissed her on the cheek as he handed her another box of chalk- this one full of colored chalk. Susie gave him a noogie.

The class of miscreants spent the next hour doing all of nothing, laughing and carrying on as if nothing had happened. A few of them rose from their seats to mock their squat teacher, replicating her stutters or words, making a game of it.

Their fun was eventually stopped when the Principal burst into the classroom, scowl on her face. “How dare you all!” She yelled at the class. “Mock your teacher. When she gives a pop test tomorrow and you all fail, don’t come whining to me. Alphys is an excellent teacher and a personal friend, and I’d very much like it if you treated her with respect!”

She stared at the back corner of the classroom. “Especially you, Kris. I’m disappointed in you, hanging out with a bad crowd. Back in my day we treated our elders with respect!”

Stealthily, Kris slid a piece of pink chalk to Susie, apparently a wager. The goat woman didn’t seem to notice. She huffed and snapped her fingers. “You’ll spend the rest of the day in silent reading.” The whole class groaned at their sentence.

They withdrew the books from their desks and grumbled, staring blankly at the pages. Toriel perched herself at the front of the classroom and opened her own book, peering up at them every few minutes. She watched as the back of the class quietly snorted at some joke. She watched as Susie grabbed Kris’ hand and pulled his desk closer to hers, and then lead his hand between her legs. She let out a breathy groan as his wrist began to flick back and forth, occasionally moaning under her breath as he groped her.

The principal bit her tongue to avoid scolding the miscreants. Why her sweet Kris had to hang out with a delinquent like Susie, she had no idea. If he could just get away from her, he’d go back to his old, quiet self. The purple reptile had practically corrupted him.
She mused sadly as she continued reading her book. The class began to simmer with hushed whispers that Toriel pretended to ignore. After all, it would be resolved soon.

The bell finally rang, and the class snapped upwards, jamming the books into their desks and rushing out of the door. The back of the class was much more relaxed, ambling towards the front as they told jokes and snickered. As they made their way out, she snapped forward, grabbing Susie’s toned purple bicep. “Not you, missy. You’ve got four hours of detention with Ms. Alphys.”

Susie turned her head to the ceiling and groaned dramatically. “That nerd? Fine, I think that might be fun.” Her eyes glinted with malice. “See you later, Kris.”

With little resistance, she let herself be led away from her buddies by the principal, whistling innocently. “I’m getting tired of this.” Toriel huffed at her. “You always have to cause trouble, why?”

The purple dragon laughed. “I dunno. Because it’s funny? And that dork teacher has it coming?”

Toriel shut her mouth. Any attempts to reach the punk would fail, and she no longer considered it worth her time. She merely walked Susie to the concrete room where they held detention, gestured her inside, and locked the door behind her.

Susie huffed when she saw the room. There was no one else to interact with. She took a front seat and withdrew a piece of chalk, grinding her teeth against it. She’d be spending four hours with the little yellow thing that was supposed to be her teacher. Susie bet herself that she’d be out in only fifteen minutes.

She gnawed on two pieces of chalk before the door rattled, and Alphys slid into the room, irritation clear on her face. “L-Look.” She stuttered. “I don’t want to do t-this, you d-don’t either. T-There… There are c-consequences to your… actions.”

Susie laughed. The little lizard was shaking in her boots! The delinquent stood up and took an imposing step towards Alphys. The teacher only came up to her navel, and she was almost twice as round. It was nowhere near a fair fight. “Don’t piss yourself!” Susie mocked her, making sure to show off her massive stained teeth.

Contrary to her expectations, Alphys didn’t cower. Instead, she lurched forward, body tensing as she grit her teeth. “You are pissing me off!” The teacher barked at her. Susie leaned backwards and lowered her fists. “I’m tired of you interrupting my lessons just to… be a bully!”

Susie whistled. “That’s new.” She snickered.

“What’s new?” Alphys asked, narrowing her eyes.

“You’re actually showing some balls for once, instead of being a fat little bitch.” Alphys growled and clenched her fists. Susie leaned forward, and hovered over the smaller lizard.
“I’ll tell you what, I’ll behave in class for a few days, if you let me leave early.” The purple dinosaur-monster tried to bargain, grabbing another piece of chalk.

“Absolutely not!” Alphys replied indignantly. “You’re being punished.”

Susie snapped the chalk noisily to emphasize her point. She crunched it darkly, a growl boiling inside of her throat. She leaned forward and placed her hands on Alphys’ shoulders, yanking on the loose lab coat that draped her body. “Oh, don’t be stupid. We both know I can keep giving you hell… or, if you piss me off too much, I could just, well, eat your face.” She snarled, sending a blast of fetid breath into Alphys’ face. Her blunt muzzle rested against Alphys’ stubbier point.

The punk began to try to push the lab coat down, which made Alphys struggle even more. This was another attempt to humiliate her, she told herself. Susie laughed.

“You know, you’re beginning to piss me off. Just unlock the door and-”

Susie stumbled forward as Alphys’ mouth opened wider than seemed possible, and her lips around the purple punk’s snout. “What the..?” She snarled, her speech muffled inside of the yellow lizard’s mouth. Alphys felt tears in her eyes at the awful chalky taste of Susie’s breath.

“H-Hey!” The delinquent growled, going to punch at her teacher. With a strength even Alphys was unaware of, she blocked the swing with one of her hands. The whiff caused Susie to lunge forward, pressing more of her face into Alphys’ incredibly tight throat. She screamed in protest, but Alphys was in no place to help her. The yellow lizard’s throat throbbed as it stretched to its limit, engulfing the punk down to her neck.

Alphys tightened her lips and rolled her tongue over the scaly flesh, her throat pulsing as she tried to swallow. She finally got a good angle, and yanked Susie further towards her, the girl thrashing all the while. Her throat clicked and made a wet cacophony as it began to tug at Susie’s face.

The yellow lizard began rubbing over Susie’s jacket, her stubby claws beginning to tear at the girl’s leather jacket. She fought in protest, but only made it worse; Alphys only had to hold her fist in one place. Her struggles helped to shred the jacket into nothing. The yellow lizard gagged as Susie’s squirming shoulders slammed against her lips. She took a deep, slow breath, and tried to open her mouth even wider to accommodate them. Her jaw creaked and began to ache as she worked, rubbing her lips in a circular motion to try and fit them.

At long last, she managed; the snap of Susie’s jacket falling apart coincided with the shoulders schlirking between her lips, the pain melting away as her maw adjusted to the massive stretch. One more hard swallow pinned Susie’s hands to her sides. As her body slumped, her perky purple tits poked at Alphys’. Each wriggle rubbed them together, an odd act of lewdness that furthered the yellow lizard’s growing arousal. Her face began to feel hot as a tingle spread between her legs.

“Okay, Okay, I’ll..!” She heard Susie beg from inside of her throat, but it was too late. Even if Alphys had wanted to stop gobbling her down, she had no idea how to pry the girl from between her lips. The girl’s thrashing became more furious as Susie was mashed by her teacher’s throat.

Alphys blinked back tears of strain as her throat contracted and dragged the girl’s perky tits inside, her nipples rubbing against her predator’s teeth and drawing her to squirm even more. As the bully began to slump closer and closer to the ground, the process was only expedited. The breasts had been another moment of strain, but they had opened her maw to the point that Susie’s toned six-pack slid between her lips with ease.

The yellow lizard’s increasingly greedy hands jammed between the belt loops of Susie’s tight jeans. The girl had begun to roll her hips in another attempt to stop the process, but it only expedited it. Her wriggling helped Alphys get the jeans off of her ass, and once they were past her knees they sloughed off with ease.

Alphys’ chubby gut began to swell as Susie’s face was spit out by her teacher’s esophagus into a slightly less tight chamber that groaned eagerly at her arrival. The sound of the lizard’s heartbeat boomed above her. As she was lowered down, her face made contact with a thick soupy liquid that burned her lungs. Her snout soon became submerged in it, and the purple punk found she couldn’t breathe. She squirmed and thrashed, this time to try and get more of herself in so that she could lift herself out of the mess.

Alphys felt the sudden panic in her student’s movement, and gripped her legs together. She gagged as she pressed backwards, jamming more of the dinosaur’s thighs into her throat. Suzy’s arms suddenly popped into the stomach, and she slammed them into the slush to press her head up. Her hands began to tingle and twitch in the liquid, a feeling that was suspiciously absent from her face. She coughed to try and get the mush out of her nose, and a great deal of it emerged. It was a good thing that Alphys’ stomach was so dark. Otherwise, she would’ve seen the purple-tinged mush that erupted with the acid.

At last, Alphys’ stubby hands snatched Susie’s kicking feet and gave her toes a rub as she mashed them past to her lips, her lips finally touching one another as she swallowed a few more times. Susie crumpled into a crude ball as her body was fed through Alphys’ tubes, at last entirely surrounded by her stomach.

“A...All bark… and no b-bite.” Alphys stammered out what sounded like a cool one liner. She hoped that it actually worked. Her stomach weighed her down to the floor, and kept her from most movements. Exhaustion yanked at her bones.

“Let me out, now, you little dork!” Susie demanded, punching at the walls of Alphys’ stomach with full force. She only accomplished creating a small visible bulge, and displacing enough air to make her teacher release a wet, slovenly belch, taking with it all of Susie’s fetid air. Thankfully, the yellow lizard felt merciful, and quickly swallowed more. There was still enough of a delay that her student was gasping for breath and squirming as her body tingled, coated in a thin layer of mush.

Alphys all but ignored her, hands dancing over her bloated stomach in a proud disbelief. Her stomach began to glorp and groan as it contracted, chewing on Susie. Alphys’ stomach, the punk soon realized, was lined with rough protrusions that made struggling or rubbing only grind into her faster. She heard Alphys panting above her, and the stomach began mashing against her in a solid rhythm.

The yellow lizard was humping at the stomach bulge, otherwise unable to reach her pussy with her hands. Her student thrashed in protest, apparently not having learned anything. The liquid mashed into Susie, bringing with it a steady drip of purple soup with it. She couldn’t see it, nor feel it, but the punk was already melting.

Susie crossed her arms and pouted in silence as the motion stopped, attempting to plot the demise of her teacher. She was snapped out of the fugue state by a loud snap, and then a rain of coarse dust over her. The stomach acid fizzled and bubbled as more and more of it snowed in.

Alphys had stretched over to the desk, and was eating piece after piece of chalk. She powered through the whole box, questioning all the while how the dinosaur endured the taste or the texture.

Once she had finished (and her teeth were caked in the stuff) she gave her gut a smack. “You know that chalk is an antacid, right? It’s basic.” She lectured her meal. “You would have known that, if you had paid attention last week in science class. And what does an antacid do?”
Susie grumbled some profane response. The yellow lizard, struck by a sudden confidence, slapped her gut, drawing a few crackling burps upwards.

“Wrong. It weakens your acid. Meaning you’ll digest slower.” She left the taunt in the air.

The numbness became more noticeable as Susie’s melting began to slow. Previously, her body had been dissolving in quarter-sized drops of purple, but now they were only coming in pitiful raindrops. Every squirm Susie offered was less destructive, but she grew overconfident; punching at the walls and wrestling them. It did far more damage than staying still with full-force acid.

Alphys thanked her lucky stars that her stomach was capable of digesting bones. Had she not been focused on punching the stomach with so much vitriol, Susie would have noticed that her fingers were almost completely gone, leaving only the stubs of her knuckles do damage. She snarled out something, her voice gurgling weakly as reality caught up with her.

Content with her taunting, Alphys resumed her earlier pleasure, thrusting her hips against the stomach. Her cunt soon made contact with Susie’s soft snout through the flesh, slamming her ribbed stomach walls against the delinquent. The purple punk, realising what was happening, pleaded for mercy, and promised to behave herself, successfully scared straight. She took it as a sign when the thrusting stopped.

However, it wasn’t to be. Alphys had squirted all over her stomach, and the mix of a post-orgasm and post-meal exhaustion yanked her into a deep coma.
Susie whined as she felt the stomach mushing down on her, Alphys using it as a waterbed. She groaned and tried to hold the walls up, but they only mashed her hands down further. She protested a few more times before the stomach began to move without the restraint of its owner, chomping over the purple punk without any semblance of mercy. Only a few moments after the teacher had fallen asleep, her problem student was nothing but a mauve mush that was draining into her colon.

Alphys snapped awake to the ring of the early morning bell, and squirmed as she tried to remember where she was. It all came flooding back when she saw her stomach, fattened a great deal and sagging downwards. She could feel her ass trembling with even the slightest movement.
Her lab coat barely fit around her, riding up over her massive gut and exposing her bare ass. She scowled and looked over herself. Her tits and ass were speckled with purple spots, along with her thighs. The teacher grumbled as she pressed herself off of the ground, still scolding Susie for causing trouble.

On the cold desk of the detention room, she saw a steaming cup of coffee and a stack of papers. A note was attached to the cup of coffee, slightly splattered with coffee.

“Great job making an example!” It read, in the principal’s warm scrawl. “I went ahead and made copies of the pop test for your class. Don’t worry, I already graded Susie’s.” A smiley face was drawn at the bottom. At the top of the stack of tests, one already had the punk’s name on it, along with a big red ‘F’ on the top. She downed the coffee in two gulps, and grabbed the stack, waddling towards her classroom.

------------------------------------------------------------------------------------------------------------------------------


She burst through to the silent stares of each one of her students, save one. “Damn, teach got thick!” One of the kids whistled out, with a few others shushing him awkwardly. Alphys felt her usual nervousness returning.

“A-Alright!” She slapped the tests on the student’s side of her desk. One of them fell to the floor, and without thinking she bent over to pick it up. She exposed her massive, sagging ass to the class, provoking another wolf whistle.

“P-Principal Tori said that… there’d be a pop test..!” She stammered. “H-Here it is, please come and take one…”
She bit her lip. The coffee was already rushing through her, creating an uncomfortable knocking on her back door. She tried to squeeze her legs together to hold it in.

Noelle and Berdly came forward first, grabbing their tests and shooting off. The other students soon followed, much more sheepishly. Kris had turned a bright red at the sight of his teacher, and tried to press his arousal down. He raised his hand, not rising from his seat.

“Ms. Alphys?” He asked sheepishly. “W-Where’s Susie..?”

“Yeah!” Another student piped up. “There’s one that already has her name on it. It has an F on it, but it’s blank.”

The class glared at her, all except for the two good students who worked diligently. “Well, I, uh…” She stammered for an explanation. The call of the wild was upon her. The teacher didn’t even think. She hopped into her chair, and squatted ever so slightly downwards, laying her bare ass over the pre-graded test. She grunted as a few firework farts crackled out of her, and the class watched in horrified confusion. Her lab coat was held up by her newfound rolls of fat, leaving her spotted ass bare.

Alphys grunted as her hole began to pulse and quiver, before the tip of a lilac log poked between her cheeks. It was flecked with fuchsia hair, and a scant few dots of white marred the log. The yellow lizard huffed as her asshole spewed out a clay-like turd. “Ah… I’m… sorry…” She almost apologized, flustered by the whole event.

The first long eventually began to break under its own weight, slapping the test with a wet thud as another chunk of the wrist-wide rope flopped on top of it. She farted, and sent out a much thinner bundle of shit-strands onto the pile, before a few more thick logs began to swirl atop the mess.


By the time that she was done, the pile that had once been Susie was coiled up at least a foot high, a mauve mass of mulched miscreant that practically steamed in the open air. As she carefully stepped off of the desk, she grabbed the last unmarked paper (that was supposed to go to Kris), crumpled it ever so slightly, and wiped her ass of the greasy residue of the delinquent. She tossed it into the trash bin, as a bit of steam wafted from the wasted paper.

“T-That’s what happens to students who behave so inappropriately.” Alphys barked at them, an odd confidence peeked from her meek shell. She saw Kris’ hand going into his pants, mouth agape and panting.

“Looks like someone else failed their test…” She drew attention to Kris, who sheepishly attempted to bury his face in the desk as well as cross his legs. “No worries, Kris. You’re more than welcome to make it up after class, in detention.”
