The class is quiet and attentive at the all-girls community college for preds. Well, mostly attentive, save for the several young women on their phones half-listening to the professor's lecture.

The professor, a tabby cat with a large, pregnant belly that one would be forgiven for assuming is full of prey given her position at the school and how close to term she is, taps a claw on the whiteboard. An illustration has been drawn on it of a wolf lady with a smaller rabbit person in her gut; it's a rather well-done drawing as well, thanks to the professor's brief tenure at an art school prior to settling for her current job.

"In this scenario, there is no hope for the rabbit," she explains, "I'm sure you're all aware that it's hopeless for prey to escape when inside of a pred, but for this rabbit, it was hopeless long before he was swallowed. As a smaller prey species, he had little chance of escaping once the wolf closed in on him."

The cat gazes around the room at the foxes and lions and tigers and crocodiles and wolves sitting at their desks, "Any questions?"

CREEEEEAAAAAK GURRRRGLE

The door to the classroom slowly opens, and though the sheepish rat on the other side takes a moment to push it open and lug his belly into the room, the gurgling of his gut is audible before he even touches the handle.

He's two feet tall with a pair of plain rectangle glasses, a shy freshman put in the school despite his gender and species due to a paperwork mix-up that was never rectified. His gut blocks much of the view his peers can get of him, though; it's easily several times his size and squirming with what must be three or four girls, all plenty larger than he is.

"Erm, sorry I'm late, Mrs. Ferz. I was just catching a quick snack before class, but they took a little bit to go down with how hard they struggled. They don't usually put up as much of a fight," he says awkwardly as he makes his way towards his desk, bumping desks and chairs and students slightly to either side of him as he makes his way to his seat at the back of the class. Each student he brushes shudders from the sound of gurgling and the horrible screams coming from inside.

"Melvin, this is your first week and you've already eaten over half the student body," the teacher comments, "Do you really need to be eating this many girls?"

GLRRRRGGGLE GLORP GROOOOAAN

"Sorry, professor, I just get hungry a lot, especially with how appetizing the ladies here are," Melvin takes his seat and lugs his belly up onto the desk in front of him. It spills over all sides of it due to its sheer size, and the muffled screams grow briefly louder as he resettles the contents of his gut.

His enormous belly brushes against the back of a wolf girl's neck, seated in front of him. She ducks her head down and flattens her ears, leaning forward to focus on her phone and not draw attention to herself.

whoops late to class again :( cant help it when these girls always get my stomach growling tho <3

She scrolls to a post by the very rat behind her, accompanied by a poorly-shot picture of himself gulping down a hawk girl. Only his lower jaw and the top of an already very full belly are in frame, along with part of the torso of his struggling prey. She glances at her girlfriend in the desk beside her, contemplating if they should just leave while they can.

HUUUUUURPH PLAT

The hair of her arms standing up and the tension with which the wolf grips her phone are eased none when something hot and wet splats onto the back of her neck. She cautiously peels it off to find an acid-tinged section of scales, seemingly from a snake or lizard peer of hers. She silently prays it wasn't the friend of hers that her mind immediately jumps to, but with how few reptilian girls there are in the school, it likely was.

"Oomphf, excuse me," comes the modest voice from behind her. Melvin wipes fur, both orange and gray, off his gut along with a few stray feathers.

GLRRRRFFF CHURRRRRN

As much as Melvin does intend to pay attention, he can't much hear over the sound of his gurgling gut or see through the mass of his own belly in front of him, so he resorts to pulling out his phone to browse social media until his meal has settled down a little.

SNAP

He posts a selfie of himself and what of his belly fits in frame, leaving his maw hung open and tongue lolling out in attempt to mimic all the hot pred selfies that are so popular online, but with his physique, facial structure, and poor photography it looks goofier than it does sexy.

digesting some girls in class :D im loving this new school even though i was put in here on accident :) its tough making friends as the only boy here but teh food is great!!!

He begins scrolling through his feed, post after post going by. Most of his friends list is comprised of girls from the school, thanks to the app recommending nearby people to add, though most who accepted did so without even knowing who he was or in hopes that accepting him as a friend would save them from his stomach.

He scrolls to a post one such friend made a few hours ago. It's a selfie from a fox girl with a bright orange coat of fur and an incredibly large baby bump. She's smiling and holding up a peace sign.

last day before maternity leave!! cant wait to introduce my new pups 2 the world! doc said theyre very healthy :D

The next post in his feed from a few minutes later is his own. It features the very same orange coat of fur on a fox girl sliding head-first down his throat. Her pregnant belly hangs out of his maw, everything above it only bulges in his throat and gut, leaving her legs kicking in the air.

being a pred is such hard work some days but feeling those squirms inside is so worth the trouble of swallowing a preggo belly down :p i love eating #PregnantGirls

He rubs one hand over his squirming gut, the fox girl still trapped inside, and continues scrolling with the other. After a few more posts, mostly just school activities with the occasional memorial for someone he'd eaten in the past week, he finds another post of interest. A panther classmate of his changed her relationship status to single a couple days prior, captioned:

I can't believe she's really gone. Three years and so much love together... I'll miss you, Eliza </3

He scrolls to the comments and types something out to reply with.

im so sorry for your loss that must be heartbreaking :( she made a great dump though her skull made me cum buckets sliding out of me <3

CHURRRRN

Melvin is distracted from his social media feed rather suddenly by an ominous rumble from his baggy, oversized shorts. A curled-up bulge longer than his leg is forming in them, not that he can really see it past his giant gut. He's worked himself up quite a bit between his meal and scrolling social media reading about his doings, and now he's in dire need of release.

"Erm, professor," he calls out sheepishly, raising one hand that isn't terribly visible over his giant gut.

"Yes, Melvin?" the cat teaching the course asks, trying to treat him with the same politeness she gives her other students.

"Is it alright if I, uhm, get off in class? I'm churning up a heavily pregnant fox girl right now, and digesting really pregnant girls always makes me so horny. Sorry for the disruption, it just, ahem, makes it difficult to focus on the lecture." Melvin speaks with a quiet tone; he wouldn't be making eye contact even if his stomach weren't blocking his line of sight with the professor.

The tabby cat only sighs, "Just don't make a mess, please."

With a grunt followed by a gentle sigh of relief, the rat pulls down his pants and reveals an enormous shaft with balls of proportionate magnitude. With his gut spilling over the desk in front of him, his shaft pokes up and rubs against the bottom of it. It takes a little doing to reach around his gut and stroke his cock.

FAP SPLAP PLAP GLRRRRGGGF BZZZT

As Melvin pleasures himself, his phone vibrates. He checks it with his free hand to find a text from a peer he was assigned to work with for a group project.

have you seen jessie anywhere? she didnt come back to our dorm last night

Typing one-handed, he manages a reply.

shes currently clogging one of the digestive sciences building's toilets

sorry i put it out of order i didnt know shed make such a mess our janitors would quit like that

seriously!? she was the one doing all the research for the assignment

and right before her wedding day too?

The rat masturbates harder and faster as he replies again then closes his phone.

sorry she was just so appetizing and i wasnt in the mood for anything in the fridge

PLAT PLAP FAP GRRRFFFGLRRRRRRGGGG

The wolf seated in front of Melvin whimpers quietly as the sound of the rat's quiet, short moans and intense masturbation mingle with the sounds of his stomach gurgling away the still-living girls inside, girls just like her. She can barely hear the teacher's lecture over the cacophony behind her; she's saying something about snakes being natural predators of rats and how low rats are on the food chain. A muffled scream from inside of Melvin sounds like it might be her reptilian friend inside shouting her name.

PLAP PLAP PLAP SPLRRRFGLRRRT HSSSSSSSSS

Just as the young woman is considering walking out of class for her own safety, maybe dropping out or switching schools, Melvin erupts behind her. His enormous cock points up from under the desk and gushes gallons of sticky, acidic cum all over her upper body. With an intense sizzle, the gooey remains of her head slough down her melting torso before Melvin is even finished with his orgasm.

SNAP

Side-eyes toward the short rat pred were frequent before, but it took a moment for the professor to pause her lecture and all eyes to turn to Melvin, holding his phone to snap a picture of the cum-soaked lower half of the wolf's body. By the time he gets the photo taken and puts his phone away to respond to the professor, all that's left of the wolf is half of a pair of legs sinking into a puddle on the floor.

The cat standing by the whiteboard sighs, "She was captain of the volleyball team, you know. Not like we have more than half the team left by now anyway..."

The cum puddle's girlfriend, a dog sitting in the next desk over, stares in shock. She holds her hands over her mouth and collapses out of her seat sobbing in horror and grief. A sizzling echoes through the room, and before she recognizes that she's fallen directly into the acidic puddle, her arms have melted almost completely, much of her legs going as well. It takes all her strength to toss herself from the puddle, landing face down on the floor inches from the sticky, white remains of her lover.

"Sorry, sorry," the rat apologizes, rubbing the back of his neck and smiling awkwardly, "my cum makes quick work of canines. I guess I just got a little overzealous there."

The professor shudders a little. The class stares between the rat, whose full gut is still moving with his slowly dying prey, the puddle on the floor that used to lead the volleyball team, and the spontaneously-amputated former girlfriend of said puddle. After a moment, the professor hesitantly returns to her lecture. Between fear of provoking the pred and the lack of any preparation for a situation like this in all her years of teaching the course, she decides to just keep lecturing. A few students leave their seats and silently make for the door. Most just scoot their chairs an inch or two further from Melvin and keep their heads down.

As the class slowly returns to as close to normal as it can be with one of its students dead and the other half-melted wallowing in anguish on the floor, Melvin quietly returns to his phone and posts the picture he'd taken of the wolf's remains.

whoops :p teacher let me relieve myself in class but our volleyball cap couldnt handle my cum lol

Regaining her composure, Mrs. Ferz continues speaking, "Now, foxes are among the lesser predatory species; they don't have the same capacity as species like wolves, bears, and crocodiles. And that's nothing to be ashamed of, to those students of mine who are foxes. Foxes as well suited to devour smaller prey species like birds and rodents. In fact, over ninety percent of altercations between foxes and-"

GRRRRRRMBBLLLE GLRRRRRGGGGGGLLLLLE

The professor stifles a groan as the rat again distracts the class, his stomach growling louder than ever as the squirms inside get more and more intense.

"Eheh, sorry, Mrs. Ferz, my stomach really wrecks foxes so she must be suffering a lot in there. I'm sure she'd be even louder if she hadn't already screamed herself hoarse. Really sorry for the interruption," Melvin responds to the silent prompting.

A fox classmate a few desks over lets out an involuntary yelp and cowers at her desk.

"With how little must be left in there, she probably isn't pregnant anymore either," the rat adds.

GWRRRRRFFFFFG GRRRRRRGGGGGGLE GLRRRRP UUUUUUURRRRRRRRRPH RRRRRRRRRRRGGGGGGGGGH

The fox squirming inside his gut suddenly thrashes violently then ceases movement entirely. Melvin lets out a loud belch, and his guts rumble loudly as they rapidly process her. He soon feels a particular need to 'go'.

"Excuse me, professor, but may I, ehem, relieve myself of my prey in here? My gut should stop being so loud once they're all out of me," Melvin asks.

Reluctantly, the professor obliges, hoping that after this he'll finally be done, "Fine, just please pay attention. We're quite behind on this lesson already."

"Thank you, Mrs. Ferz," Melvin says, standing up on his chair with his pants down and leaning his bare ass over the back of the seat.

Mrs. Ferz returns to her lesson, though she pauses as she turns back to the whiteboard from feeling one of her kittens kicking in her womb.

FBLRRRRBLRRRT SPLRRLRTCH BLRRRFRBLRT

While he never lied about his gut no longer disrupting the class, the sound of enormous logs of former girls splattering onto the ground from his stretched-out pucker certainly does. A few miscellaneous bones scatter in the pile forming behind him where the coiling log folds over onto itself again and again as it's forced out of him. 

The professor resorts to talking as loud as she can without outright shouting to not have her class run over the scheduled time, especially since that'd mean more time in proximity to the ravenous rat. She moves on to asking review questions to ensure her students understood the lecture.

"Now, who can tell me a fox's role in the pred prey dynamic? What species are a fox's natural prey?" she asks. Only one hand goes up.

"...Yes, Melvin?" she reluctantly addresses him.

"A fox's natural prey are-" Melvin stops to grunt as he pushes out a particularly thick part of the giant shit coil snaking out of him, "birds, squirrels, and- fuck she made so much shit-"

BLRRRRBLRRFRT SPLORTCH

Melvin reaches the end of the giant log, with a pelvis caked into it, and he lets out a hefty, liquidy slue of shit that erupts from his ass like a geyser. In the spray is the skull of the pregnant fox he'd devoured before, along with three tiny skeletons of her unborn pups, the bones of which scatter all over the growing pile behind him. Two dozen more fox bones pour out afterward before another dense log crowns his hole and begins to press out into the room.

"-and, uhm, uh, rodents, such as rats," Melvin finishes his response, speaking in complete sincerity.

"That's- that's correct, Melvin," the pregnant professor says, "Now can someone name other natural predators of smaller species such as birds and rodents?"

Not a single student is paying the lecture any attention except for the rat presently packing the back of the room full of shit. The professor again has no choice but to call on Melvin.

"That'd be- mph- birds of prey like hawks-" 

FRRBLRRRFGHT KLRRGPFRRRBLRG

An avian skull slides out of Melvin's donut hole caked into the top of the thick stream of shit and rides it down into the foul mess below. 

"-And many reptiles such as- hnnngh fuck she feels good coming out- uhm, snakes."

FBRK SPLRRRRRFGGHHHH SPLRRTCH

The dense coil briefly stops and the rat's ass closes up slightly as the skull of a snake presses out and catches its upper and lower jaw on the top and bottom of his hole. The jaws open from the force of the scat inside pressing on them, and the log splits into several as it spews out in all directions from the snake's eyes, nostrils, and maw. After a few moments, it comes loose and joins the mess below.

"And now who can give me an example of an apex predator at the top of the food chain?" the professor is again forced to call on Melvin.

"That would be-"

BLRRRRFGHT FBLRRRFT SPLRT

A candid skull sloughs out into the steaming slue piled up all the way to the back wall behind Melvin, followed by a hundred more bones that used to comprise the skeletal structure of a young woman seeking an engineering degree. His cock twitches as he thinks of the volleyball captain who is currently several gallons of his cum pooled on  the floor.

"-Wolves."

The slue of shit finally ends, Melvin left huffing where he leans over his desk, his gut now empty. The professor stares blankly at the immense heap of shit filling the back of the classroom. 

"Class is now dismissed," she says, managing a polite tone.

All of the class's students trip over each other running for the door, save for the half-melted dog on the ground, half-alive at best, and the predacious rat.

Melvin takes a picture of the enormous shit pile and posts it to his social media.

shame our janitors already quit :p the girls here just make so much shit when i churn them ^u^

 He then walks up to the professor, still pantsless.

"Ehem, sorry to keep you, Mrs. Ferz, but uhm-" Melvin begins, touching his index fingers together shyly.

"Yes, Melvin?" the professor asks.

"Could I fuck you to death? I'm sorry, I know it must be really inconvenient right now since I'm sure you have more classes today, but pregnant cats just make me so horny. Plus thinking about wolves... well, I just need some release."

The cat is taken aback by this request, especially with the kittens she's carrying. 

Melvin doesn't wait for her response before grabbing her and bending her over onto the ground. With how short he is, he doesn't need anything else to lay her on. He grips her by the hips and slides his gigantic cock inside. "Thanks, Mrs. Ferz; you're a lifesaver."

PLAP PLAP PLAP CRUNCH

The first two thrusts work the enormous shaft into her cunt. The third pushes all the way inside, instantly slaughtering the twins she was carrying and changing her pregnancy bulge into the broad outline of Melvin's cock.

The moment the rat's cock forces its way inside of her, something changes in Mrs. Ferz's head, a sudden shift in paradigm as her purpose to satisfy his needs is bestowed upon her like a divine revelation. Any desire to resist evaporates despite her mulched kittens.

PLAP PLAT SPLAP

"Mmgh, sorry about your kittens," he says politely between thrusts, "but it feels so much better when they're mushed up."

"That's- augh- alright, Melvin... huff..." she says between what breaths she can manage with her lungs compressed along with the rest of her guts by the enormous shaft being violently thrusted into her.

PLAP PLAP PLAT

"When were you due?" he asks casually while ravaging her insides.

"In- ngh- a week," the professor chokes out.

SPLAP PLAP PLAP PLAT PLAP

Melvin huffs and intensifies his rhythmic motions, immensely aroused by the response. His cock was already causing the professor a lot of pain from its size and the force behind it, but now it's like a jackhammer being taken to her guts.

Mrs. Ferz sputters out agonized breaths as Melvin continues the conversation, "Did you have- mph- names picked out for them?"

The professor can barely speak with her lungs actively collapsing, "S-Sally, and... nghhh- Ariel."

Her response becomes her last words as her eyes roll back for the last time and her body goes limp around his cock. After a few more thrusts, Melvin pulls out, his cock dripping with blood. He doesn't make any attempt to reach climax; he only needed the satisfaction of a nice post-shit kill.

"Thanks again, professor," he says cheerfully to the corpse he leaves lying on the ground, "That was just what I needed."

Melvin takes a quick selfie with the professor's ravaged body in frame behind him, and as he waddles out the door, he types up a caption to post with it.

prof was preggers :p couldnt help myself with two kittens in there begging to be splattered

He speaks to himself as he walks along through the hall, "Now, time to find lunch before my next class."
