"Now boarding: Flight 109, section B."
Luna gets up from her seat at the airport terminal and gets in line. After multiple delays and a lot of time spent listening to uncontrolled, screaming children at the airport, she's looking forward to finally making her trip home.
The anthro husky shows her ticket to the attendant at the gate and follows the passengers ahead of her through the jet bridge to her flight.
"WAAAAAAAHHHH WUAAAAAHHHHH!"
As soon as she steps onto the plane, her ears are assaulted by the sound of an infant crying as loudly as it can. She approaches her seat, silently telling herself the little one will be hushed down soon and she'll probably at least be a few seats away from it anyway.
She arrives to her seat to find it right next to a calico cat, who has on her lap a baby carrier with two baby kittens inside, a boy and a girl.
"OOOWWAAAAAAHHHHH!"
As she sits down and buckles into her seat, the second of the twins begins to scream just as loudly. Luna opens her mouth to say something to the mother sitting next to her, but there's not a moment of silence for her to speak through.
The cat has bags under her eyes and a blank expression. She briefly glances at Luna and almost seems to scoff before turning her head away and staring blankly out the window, making no attempt to calm her babies down.
After a long, grueling hour of waiting as the rest of the plane boards and they're cleared for takeoff, they finally reach the runway. Luna has been holding onto hope that the mother might be waiting for the plane to reach altitude before tending to her children, but she's soon proven wrong.
As the pilots prepare for takeoff, the mother puts in ear plugs and pulls out a bottle of sleep aids. She downs a couple of pills dry and puts on a neck pillow.
"WAAAAAAAAHHHHHHH WWWWAAAAAAAHHHHHHHAAAHHHHHH!"
By the time the plane has ascended, the mother is fast asleep, and her babies are still crying just as loudly as before.
For a while, the husky persists, albeit irritated, trying to drown out the continuous noise with her headphones, though she can't quite overpower it with her music without hurting her ears from the volume.
She's content to simply have a miserable flight until suddenly the crying stops from the first twin, and the other quiets down shortly after.
Luna looks over at the babies, surprised by having silence for the first time since she'd boarded the plane.
FBLRRFT CRINK
The baby boy messes his diaper, blorting it out. Luna turns her nose away in disgust, assaulted by the stench. The mother still doesn't stir from her sleep.
PFFRBLLRT CRINKLE
The baby girl soils hers right after.
"WAAAAAA-HAAAAAAHHUAAAAAAHHHH!"
The crying resumes not a minute later, and Luna slumps forward with her face in her hands.
She's had enough.
Luna gently prods the mother sitting next to her on the shoulder. Then she gives her a small shake. Nothing. She won't notice a thing.
The husky leans over the open baby carrier and carefully scoops up one of the infants. It cries harder. She reaches for the other and gets up out of her seat.
All eyes are on her as she walks to the plane's bathroom, one stolen baby in each hand.
"Sorry about the noise, just going to change them," she lies to a passenger who gives her a particularly curious look.
She enters the cramped compartment and locks the door behind her.
The two stolen bundles of joy look up at her with big, terrified, beady eyes between loud bouts of crying. Luna is too tired for sympathy.
GWRRGGGLE
Having avoided the overpriced food at the airport to go easy on her wallet, the husky is absolutely starving, and she's all too eager to kill two birds with one stone.
HOMPHF-
The loud crying coming from the bathroom is halved as she stuffs the baby boy head-first into her maw. Its filled diaper crinkles in her grip as she pushes him deeper inside.
ULK GULP
It takes only another moment to swallow him, sending him down into the inescapable abyss of her stomach below.
GLRRGGGG GLORP
Her gut begins to churn up its prey, and she turns to the baby girl still in her arms. The infant cries louder and harder than before, seeing her brother disappear down the apathetic pred's gullet.
Luna sets the child on a small table beside the toilet, not concerned with her just yet. The airline's bathroom has adult diapers provided as an amenity to any passengers who might need one, and Luna has gotten an idea.
CRFK CRINK GFRRRGLGLRRR
She slips one on as the first of the infants stops moving inside of her belly, her gut as large as if she were pregnant. After just a moment, she squats down and lets loose into the diaper.
FBLRRRFFT PFRRRRR CRINKLE
A thick log of shit presses out into the diaper. The mess bloats it out, round but with indents of infant bones scattered loosely across the surface.
More mounds of brown mush and the baby's own diaper escape from Luna's rear end.
BLRRBRLLRT CRK BLRRFFT
Luna fills her diaper even more, growing it out with infant remains until it's as large as though she'd simply stuffed a baby inside of it. In a way, she has.
The little baby kitten's skull evacuates her bowels last, pressing through the mess until its snout creates a visible indent in the crinkly plastic.
Luna huffs and wipes her brow from exerting herself disposing of the baby, then she slips off the diaper and rolls it up tightly. She's able to place it into her purse with room to spare.
Her eyes wander to the baby girl, staring wide eyed from where she was set down prior. She begins to bawl harder than ever as Luna approaches.
"Oh, shut it," Luna grumbles as she picks up the second infant kitten.
NOMPHF-
The crying suddenly stops as the baby girl is muffled by Luna's maw. Outside of the bathroom, the rest of the passengers sigh in relief, unaware of what is transpiring within and simply glad to be rid of the constant disturbance.
GULP
The infant slides down Luna's throat as easily as her brother had, diaper and all. Luna sits down on the toilet to rest while the baby digests inside her, though she has no intention of using it any time soon.
GLRRFGG GLRRRPPP
A muffled wailing comes from her full belly as Luna waits for the baby to melt down inside of her, a pleasant change of pace from it constantly having a meltdown outside of her. The cries aren't able to penetrate the bathroom walls, silenced as they are by Luna's stomach walls around them.
GLRRRGGLLEEE
The crying gradually fades away to sweet, blissful silence, broken only by the ambient noise of the plane's engines and the gurgling of Luna's gut. She sighs contently. Finally.
GLRRRFFGGG
Only one thing left to do now.
She puts on another diaper and squats down as before. 
FBLRRRBFLLRT CRK CRINKLE
Her second diaper expands with the messy remains of another infant. This one comes out much less solid, a slurry of semi-liquid mass filled with the baby's hard but tiny bones. A half-digested, baby-sized diaper is added to her soiled but in tact adult-sized one.
BLORPBT SLRGHHBT CRINK
Luna stifles a moan as she pushes out the rest of the digested child into her diaper, bloating it out just the same as the first. The remaining infant bones are followed by the skull that belonged to the baby girl as they exit her backside, and she's finished. No more noise.
Content with her work, she removes the second diaper and puts it into her purse with the first, though it barely fits both of them.
She wipes her rear end clean of any infant cat that may have gotten on it, and she quietly exits the bathroom. Nobody seems to notice that she had entered with two babies and left with none.
When she arrives back at her seat, she finds the former mother still sound asleep. Luna sits down and pulls the filled diapers out of her bag.
She replaces the infants in the baby carrier, just the same, but with a new, brown makeover. She covers them with the soft blanket at the bottom, so as to prevent anyone from noticing what she's done and to prevent the smell from escaping.
The rest of Luna's flight passes in peace, no excessive noise, no bothersome stench, no insufferable infants. She's able to relax, lean back as far as the middle-class airline seat will allow, and listen to her music at just the volume she prefers until landing.
It's now hours later. The plane is on the ground at the airport, and only a few passengers remain in their seats.
A flight attendant finds the mother asleep in her seat and gently nudges her awake, taking a few moments to rouse her from her sleep. The calico grumbles and mutters something as the flight attendant moves on from her.
Just as she's preparing to get up, she notices a foul smell and looks down at her babies in the carrier on her lap. She doesn't recall covering them up like that.
She pulls back the blanket to find two soiled diapers, filled with tiny bones where her babies should be.
