Ami wakes up in her crib, slowly opening her eyes. 
SLOSH SLRSH
The diapered lion cub is resting on her enormous, bloated gut. It's empty right now, save for several gallons of stomach acid sloshing around inside, but it remains large enough for Ami to sleep on like a water bed.
Once the hungry little 6-year-old cub had devoured enough prey, her tummy remained fairly stretched out, but she's never minded it. Her crib had to be custom-built to fit it, though.
GRRRRWWWWWWLLLL
Still, it sure does make her hungry.
"Ami! Time to get up!" her mother enters the room, giving her a feline smile from the doorway, "You've got a field trip at daycare today!
Ami lets out a big yawn and pulls herself up over the edge of the crib before hopping to the floor. It takes her another brief moment to hoist her belly out. The sloshing tummy does nothing to slow her down, though, as she makes her way to the breakfast table.
"Good morning, Ami," her father says warmly, flipping some eggs in a frying pan, "I made your favorite!" A bit of yolk has gotten in his mane, which Ami silently giggles at without telling him about, "Thank you, Daddy!"
Ami's mother has already taken a seat at the dinner table, and Ami's father soon joins her. The table is large enough to seat twelve at large gatherings, and every inch of it is covered in food.
"Come eat your breakfast, sweetie," Ami's mother beckons her while she excitedly gazes upon her feast.
Entire rotisserie chickens wait buttered up on platters, plates of stuffing and yam and potatoes and ham are scattered all over the table next to bowls of soup and corn and gravy and beets. Whole pears and apples and full bunches of bananas and even a watermelon fill the space between dishes.
In the center of it all on one massive platter is a gazelle from Solara, the next planet over. Her arms are bound tightly behind her back, and her legs are tied firmly with her knees to her chest. She gets wide-eyed at the sight of Ami and her large, sloshing gut, but she's been gagged and can't make a sound.
Ami's parents watch her over small plates of bacon and eggs as the little lioness tears into the feast they provided.
OMPH- GULP NOM SLRP
Ami immediately stuffs an entire pear down her throat, then dumps in a plate of stuffing right after. An entire bunch of bananas disappears, and she doesn't even slow down to peel them.
GRRRGGGGLE SLOSH
A rotisserie chicken goes down the hatch, followed by an entire watermelon. Ami dumps a full bowl of gravy into her maw and swallows all of it. The ravenous little one stuffs an entire ham down her gullet and barely notices that she's swallowed the platter with it.
NOM SLRRP GULP GLRRRRGGLE
She's already digested a good portion of the food as she continually stuffs in more and more. Corn, beets, apples, chicken all disappear down the cub's throat. By now, she's on top of the table, laying on her gut as she shovels anything in arm's reach into it.
GBLRLRFBLT CRK
As she continues to stuff herself, she already begins to soil her diaper, a small brown bulge in it ballooning out as fresh poop sloughs into the pamp.
FBLRRBRLLTL CRINKL FBLTLRLTLRLLSCHLRT
The gazelle squirms uselessly against her restraints as Ami fills her pamp without slowing down her feeding frenzy. Soon, the little girl's diaper is bloated with a feast's worth of waste, and the only things left on the table are the gazelle and plenty of crumbs.
NOMPHF-
Without paying any mind to the terror in her prey's eyes, Ami stuffs the gazelle's head into her maw.
GULP ULP
The cub effortlessly lifts her off the ground and begins stuffing her down her throat. It takes only seconds for her entire body to disappear down the cub's gullet.
UUUUUUOOOOOORRRRRHHP GRRRRRRRRGGGLE SLOSH
Ami sits with her legs wide apart on the table, her full, busy stomach in front of her and big, full diaper behind her. Her prey sloshes about inside with what little range of movement she's able to muster while all tied up.
SLRSH SLORSH GLRRRGGLE
"She was real yummy! I wanna have more like her," Ami says.
"Maybe one of these days, sweetheart," her mother responds, "Your father and I had to take a full day off to get our hands on her over on her home planet."
"Awwww, Okayyy," Ami responds.
It's not long before the trapped prey stops moving, starved of air in Ami's acids. Shortly after, the gazelle is ready to come out.
FBLRRBLTLRLLT CRINKLE FBLRRRRR BLORT
The pamp balloons out even bigger than before, and Ami lets out a contented sigh.
"There you go," her father says as he gets up to change her diaper. The proud lion grabs a clean pamp out of a drawer along with some baby wipes and pulls out a Diaper Disposal Unit from under an end table in the corner of the room.
The little one's diapers have padding a foot thick to contain her big messes, so the fresh one is quite bulky in the father's hand, even folded up fresh out of the package.
CRRINK
He undoes the over-filled diaper just enough to pull his daughter out of it and wipe her rear end clean before diapering her back up again.
CRINKLE CRK
He activates the DDU, and the diaper that dominates the diameter of the dinner table disappears into a small slit, shrinking down to fit into the device several times smaller than it is.
"Mmm, breakfast was really good! Yummy," Ami says, rubbing one hand over her massive, once again empty belly in a circular motion.
SLSH GLRRP
"I'm glad you liked it, sweetheart," her father says.
"Are you ready to go to daycare?" her mother asks.
"Yeah!" Ami says excitedly. She hasn't looked forward to daycare like this in a long time, but today's field trip is very exciting.
"Alright, then, sweetie, come on," she beckons her little one to the door.
"Have lots of fun for me!" her father calls from the kitchen, where he's putting the dishes that didn't get consumed in his daughter's rampage into the dishwasher.
The trip to the daycare is uneventful, but pleasant. Ami gazes out the window with her arms wrapped around her big tummy as she watches the trees pass below their flying car.
When they arrive, Ami's mom gives her a big hug, one arm over the little one's gut and one arm around her back, "Have a good day at daycare, sweetie."
"I will, mom!" Ami waves behind her as she walks in the front door.
Daycare is nice, with a dozen other lion cubs toddling around, playing with small toys, and tackling each other. Three supervisors watch over them to keep them from playing too rough.
Ami walks over to two of her regular playmates, Tonir and Jri, both little boys her age. One rolls a toy train back and forth while the other builds a tower out of blocks.
"Whatcha doin'?" she asks as she sits beside them.
"I don't know what Tonir is doing, but I'm about to crash a train!" Jri says.
"Crash it into what?" Tonir asks before his question is answered by Jri's train smashing his tower to the ground.
SLRSH GLRP
Several of the blocks bounce off Ami's belly, and Jri's run of destruction ends with the little toy train smacking into it as well.
"Well, how about it goes into a tunnel?" Ami asks, pulling the train from Jri's hand and putting it in her mouth. She uses one finger to push it down her throat.
GULP
"Hey, my train! Wait- you can do that? That's a lot to fit in your mouth," Jri responds.
"Yep!" Ami boasts, "I can eat whole people if I wanna!"
"Is that how your tummy got so big?" Jri asks.
"Mhm! Just like this!" Ami grabs Jri by the wrist and puts his hand into her mouth.
SLRRP
"Hey, h-hold on-"
OMPF-
Ami stuffs Jri's head and shoulder in next. She pulls him onto her gut and sits back to easily slide him deeper in off of it.
SLOSH GLRP CHURRN
Jri soon disappears entirely down Ami's gullet. His little paws kick helplessly in the air as the last of his is slurped down like a spaghetti noodle.
ULP GULP SCHLLLLRP
"See?" Ami says as her tummy squirms around.
"Woah..." Tonir says as he watches.
Imprints of Jri's hands scrabble at the side of the gut, halfway up it due to his position floating in Ami's acids.
Ami and Tonir watch the struggling playmate alongside a few other whose attentions are drawn to the curiosity as Jri slowly stops moving.
"It's always fun when they move around like that," Ami says, "My tummy melts them real quick once they stop struggling in there."
FBLRRRBT CRINK BLRRT GLORP
Ami leans forward against her gut as her diaper grows to the size Jri had been, filling up with soft, squishy mounds of brown. "And then I push them out as poop!"
As Ami relaxes and waits for a diaper change, another girl two years younger than her approaches, "How'd... How you do dat?"
"Oh, it's really easy!" Ami says, pulling the girl close.
"First, I open my mouth real wide like this, aaaaaaaah~" Ami opens her maw.
"Den, I puth de prey's hed in like dis," Ami speaks without closing her mouth as she stuffs the girl's head into her maw.
"An' I juthd sthwallow!" Ami talks with her mouth full before immediately gulping the little girl down.
GULP GLRRRRGGGGLE SLRRRSSH
"And then my belly churns them up reeeeeeal good," Ami continues, though her prey is too busy struggling helplessly in the gallons of acid inside of her to really listen.
Ami presses on her gut as the 4-year-old drowns in her acids, suffering the same fate as Jri before her.
She leans forward and braces herself again once her playmate has lost her shape, "And now I let them out as poopies in my diapey!"
FBLRRRBLLTT CRK BLRRT CRINKLE
"Did everyone understand that time?" Ami leans back against a diaper the size of two of her playmates.
Other kids soon gather around Ami. They prod at her diaper, gaze in amazement at her big, sloshing gut, and the more daring of them push blocks and bouncy balls into her mouth to watch them come out as poop moments later.
The crowd disperses shortly after, though, as a supervisor comes over, "Oh dear, did someone make a lot of poopies?" Her nametag reads 'Calyir'.
The supervisor is equipped with the latest in cub-care equipment; a tiny hammerspace device on her hip ejects a full-sized diaper and a baby wipe at the press of a button. "Let's get you cleaned up."
CRINK CRK BLRT
Ami is pulled gently out of the diaper, which then disappears into a compact DDU on the opposite side of Calyir's hip. 
CRINKLE TRKP
A new diaper is put onto Ami and taped into place, "Now then, let's get ready for the field trip."
All the little ones in the room look up eagerly at the mention of the field trip. "That's right, we'll be heading to Solara in just a few minutes!" Calyir announces, "We're going to watch a play be put on of The Dragon and The Three Mice. That's the book we read yesterday!"
Ami vaguely remembers eating a colorful book with that title the day before.
"We'll be getting on the shuttlebus in five minutes!"
Ami and her playmates look out the daycare window at the rocket-equipped vehicle outside, which can fit up to 100 people. A few minutes later, they look out the shuttlebus windows back at the daycare.
Their attention is drawn to the front of the shuttlebus, where another supervisor says, "Now who's ready to count down?"
The entire bus erupts into a cacophony of numbers that slowly organize into a countdown.
"TEN!"
"NINE!"
"EIGHT!"
"SEVEN!"
"SIX!"
"FIVE!"
"FOUR!"
"THREE!"
"TWO!"
"ONE!"
And with that, the spacecraft hovers up off the ground for a moment before launching up towards the stars.
