Karla sits at her desk and watches as her first grade class come back from lunch. The school children, ranging in species from pelicans to panthers and many more all talk among themselves as they file into the room and sit at their desks.
"Do close the door behind you, Carol," the fox teacher says to a small cheetah girl as she enters the room last.
"Yes, Ms. Ebbledeen," the little girl obliges.
Once the class has settled into their seats, Karla gets up from her desk and stands in front of the whiteboard. "Now, class, for today's assignment, I want you all to write down what you want to be when you grow up. You are to write it on a slip of paper and place it into this hat," she says, pulling out a top hat and placing it upside down on her desk.
"Carol, be a dear and pass out the slips of paper."
After 5 minutes of quiet chatter as the students write down their answers and get up one at a time to put them in the hat, the last answer is written and placed inside. Karla stands and grabs the hat from her desk.
"Very good," Karla says, reaching into the hat, "Let's see what you all wrote... An astronaut, a firefighter, my my, a lot of you want to become doctors."
Karla makes her way towards the door as she reads off the little slips of paper with her students' dreams on them. "Such a shame, though," she says as the locks the door, which has been changed to require a key to unlock from either side as a recent safety measure, "Because you're all about to become my shit instead~"
FLRFLRTTTR
She dumps out the contents of the hat onto the floor.
Confused murmurs break out along with a few shocked gasps that their teacher would say a bad word in front of them. Meanwhile, Ms. Ebbledeen strides up to the first of her twenty students and shoves his head in her maw.
OMPFH- GULP SLRP
It doesn't take long to move her hands from the child's shoulder to his hips and pull him further in. It's only a couple quick gulps to get him into her stomach, which grows to the size it might be if she were pregnant with twins.
GWRRRRGGGLE
The hopeful young panther who'd hoped to be a fireman is reduced to a squirming bulge in the teacher's gut in mere seconds.
Karla does the same with the next two students, a young iguana girl who'd wanted to be a doctor and a little pelican boy who'd hoped to be a sailor.
GULP ULP CHURRRRN
The teacher's shirt rips open now from her bulging gut. Karla sheds it and removes the rest of her clothing as well in preparation for what she's about to do.
Chaos has broken out in the room as Karla continues her rampage. Students cower in corners, scream, or bang fruitlessly on the door.
One child, a German shepherd boy no older than 5 has proven to be quite the young genius, a grade ahead and with straight A's, already reading at a college level. He wants to be a scientist when he grows up.
Karla pushes her desk aside to find the little boy cowering beneath it. He looks up as his cover disappears to see his teacher's bare rear end looming over him for just a moment before it slams down upon him.
PLAP SHLK GLRRG
Karla's gut is massive already, bloated with 4 children, and only a fifth of her class, yet she moves with ease thanks to plenty long years of practice with other little ones squirming inside her.
She approaches a pair of Siamese cat twins, both girls. One cowers behind the other and holds her out in front of her, in hopes of being eaten second. Karla opens wide and forces them both into her gullet at once. 
ULP- SLP- RRG- GUUULP BLEEEEERRRRLLLLLCH
It takes her a bit of strength to swallow them both at the same time, but with a mighty gulp, she manages.  She lets out a long belch immediately after.
The ravenous teacher moves on to the next student, a young dog girl in a skirt with an innocent but terrified expression. "Hmm, not yet... I still need you~" she grabs the little one and rolls her massive gut over top of her, holding her lower half up by the legs. 
After a few seconds, she manages to pull her panties out of the way and get her cock aligned with the little girl's pussy, and she begins to rut up against her, pressed between the bottom of Karla's gut and Karla herself.
PLAP FAP SMACK GRRRRRRRRRGGGGLE
Karla grabs a chair to prop up her new sex toy under her gut to allow her to continue hands-free. She'd positioned herself carefully when she began this maneuver,  setting up near a corner with five students cowering in it.
A parakeet girl with bright green feathers tries to slip by her, but Karla grabs hold of her as she tries to run and lifts her by the shirt. She stuffs the little one into her maw and gulps her down.
ULP GLRRRRGG
Two more students attempt to slip by her, but the teacher has far more dexterity than she looks like she should with 7 children trapped inside of her and another taking her cock. A young eagle who'd wanted to be a vet and a dachshund who wanted to be a baseball player disappear down her gullet in turn. Or at least that's what she thinks they wanted to be; she's losing track by now.
GULP ULP GRRRRWWWWWWLLLL
The last two children in the corner, both rabbits, try to run past her at the same time so she can only catch one of them. This doesn't work out well for the little ones, as Karla has two hands. She stuffs the children down her maw one-by-one.
GULP SLK GRRGLE GULP SLRRP UUUUUURP
She speeds up her grinding on the little girl beneath her gut, whose muffled crying is drowned out by the louder screams and panicked sounds barely piercing Karla's thick gut as well as the sounds of panic from the rest of the class not yet devoured.
PLAP PLAP PLAP SPLRRRT
Karla cums deep inside the little girl and pumps several loads into her before the strained chair propping her up breaks, crashing the little girl to the floor under the weight of 11 melting classmates.
The little one can barely move when Karla lugs her massive gut off of her. It's a bit tricky for the teacher to lean over and grab her off the ground, but she manages and swallows her cream-filled treat with no resistance.
GULP
6 more little ones are banging on the door, trying desperately to push through it to reach relative safety in the hall. Several students of varying ages from other classes have congregated to watch the madness through the small window on the door, and some of them also attempt to help open it from the other side to no avail.
Karla lugs the massive, squirming weight in her gut towards the door, backing up towards the students. Most don't realize in time that she's approaching in their panicked attempts to break through the door, and with one plop down onto the ground, she forces 3 of them up her donut hole and smushes two more beneath her, the last one running away towards the center of the room.
PLOP SCHLLLK SKLK GRRROOOOOAANNNNNN
Karla pants a little with the effort; she hasn't eaten this many children at once before, and it's a tremendous thrill to do. She pulls the sheep girl and little fox girl out from under her one at a time with some difficulty and devours them. She can barely maneuver the little ones over her gut to swallow them.
GULP GULP GRRWWWWLLLL
The last two children are a young bee girl who'd fled from the door and Carol, the cheetah Karla had often called on prior. 
By now, Ms. Ebbledeen is a slumped over mound of squirming bulges and muffled screams. The massive teacher, full of 18 of her first graders, has just about met her match. It'd be a lot of effort just to move a few feet with this massive gut.
"Ough goodness me, I'm stuffed~" she says, letting out another long belch, "I think I have room for one more. Carol, why don't you be a dear and bring Julie there here for me? I promise I won't swallow you or put you up my butt if you do~"
After a moment's hesitation, Carol obliges, dragging the struggling but much weaker bee girl over to her hungry teacher. Karla takes the bee girl by one of her four arms and pulls her close. She stuffs the little one's face up against her gut, "Looks like you're the last one to the party~ Excited to join your friends~?"
The little girl doesn't respond, and Karla stuffs her head into her maw after a short moment, the rest of the little girl soon following.
GULP ULP GLLRRRRGGGLE
Just as little Carol is about to move away from the student-filled teacher, Karla grabs her by the arm. 
"B-But Ms. Ebbledeen..." the little girl begins to speak.
"I said I wouldn't swallow you, my darling, or put you up my butt~ I have something else I want with you, though~"
The teacher forces the student onto the ground next to her then gradually shifts her weight to get on top of the little girl. With a gut several times her size, it's the easiest way for Ms. Ebbledeen to get the little one to her cock.
It certainly takes some doing, but the teacher manages to maneuver herself inch by inch and get the little girl inside of her member. Little Carol is slurped down into the teacher's balls, and Karla relaxes to digest her class.
SLKKHK GRRRRGGGGLE GROOOOAN GLOOOOUURRRP
After a couple hours, the screams have died down, and the squirming, frantically-fighting bulges have been reduced to the still, defined outlines of countless bones. 
In that time, Karla has slowly but surely maneuvered herself to the center of the classroom, which she had little trouble clearing of tables and desks with the furniture having been tossed all over the place during the commotion prior.
The teacher doesn't stand as much as she leans against her enormous gut. After a moment, she begins to release the captured students.
FBLRRRFHBRLLLGHLLLLTPLRRTLTLLRTLRR
An enormous, wet mound of brown filth caked with bones exits Ms. Ebbledeen's rear. The first semi-solid log plops to the ground with the remains of the three students she'd shoved up her rear at the door littered throughout it.
The next massive mound contains what's left of the bright little German shepherd boy and a few miscellaneous bones from other students.
The remaining turds are a jumbled mess of everyone else's remains.
SPLBFRLBLRLRLTBLRB SPLAT BFLRLLRRT SPORTCH BLORP PFRRRRRRRFRRRRRTTTTTT
More brown filth slogs out of Karla's backside and joins the mound of shit and bones beneath, which stretches out wide with all the former children comprising it. Between enormous slurries of her class, Karla's donut hole emits ear-shattering flatulence as large amounts of gas inadvertently swallowed with the little ones reaches its exit as well.
FSHBHRHSHHBRLLRWWWLRLRWLWRLWLRWLLL SBRFBHRLBKHRSFLLTTTT
Karla begins to urinate while she voids her bowels, a puddle of piss pooling on the ground in front of the growing filth pile that's consumed her ankles. All the bodily fluids of the children have become one bodily fluid of Karla.
PFRRRRR FBLRBHLTHB SPLAT
Finally, the teacher finishes dropping off her students with one last mound of brown remains and bones and skulls. Karla takes her steps away from the pile carefully and slowly to avoid slipping or having to take too many steps in the stuff as she maneuvers in front of the mess.
The mound of what's left of her class sprawls across half the room's width, and the puddle of piss spreads out well past Karla's feet and soaks most of the floor.
There's one last former child still left inside the teacher for her to deal with: the remains of little Carol in her balls. The heavy mass of cum and bones sags in her sack as she begins to masturbate.
PLAP PLAP PLAP
Already being so aroused from what she'd done to her class, with such a heavy load in her balls, and after having all that shit press up against her prostate on the way out, it takes her less than a minute to climax.
SPLFLRRRRT SPLRLT SPLAT
Enormous strings of cum cover the pile, and Carol's bones join the rest of the sorry remains, each one splatting into it in rapid succession. The little girl's feline skull is left at the forefront of the mound, empty eye sockets facing up towards the teacher with only shit and cum behind them. "What a good girl you were~"
Finally, Karla exits to the front of the room.
Before she leaves, she grabs the camera belonging to the school's yearbook club off a rack on the wall. She'd asked to borrow it days before, and now she's going to put it to use.
CLICK
Her class is surely going to have the most memorable yearbook photo.

JINGLE RUSTLE TRRRK CREEEAAK
The door to her room opens suddenly, just as Karla was preparing to go clean herself and start looking for a new job. The principal of the school, a tall-standing lion, slowly enters the room.
"Hey, Mr. Grelts," she says casually with a smile. She's been expecting to see him about this at some point, but she'd hoped it'd be through email.
"Hello, Karla," he says in a grave tone, "I'd come down here as soon as I could, but you would not believe how difficult it was to get the spare key to this room. Apparently a janitor had it and took today off."
"So do you want to have a little chat about it?" Karla offers.
"I want to see you in my office so we can discuss the terms of your severance from the school."
FLRRSFSHRHLSLRHSHRSHHHHHHHHHH
Karla exits the one-person restroom right outside the principal's office. The meeting had gone very, very well, and Mr. Grelts had taken a sudden, early retirement.
Karla had been planning on a quick one-and-done buffet when she started teaching at the Duvour County Public School, but with such a sudden change in management, perhaps she can stick around a while longer and see how this all plays out.
