An arctic fox hurries on her way to her friend Stacey's apartment. She's quite early, of course, but she's eager to see her friends again and to have as much time together as possible. After all, little gatherings like this don't happen often these days with their busy schedules.
As Melanie hurries along down the sidewalk, she comes across an intersection taped off with roadblocks and caution tape. In the middle is a deep hole in the road, perhaps a sinkhole, perhaps the result of some ongoing construction. Whatever it is, her route is blocked.
She looks about her, not knowing the city terribly well aside from the instructions she'd been given beforehand. 
Just as she's about to turn around and call to see what other route she can take, she notices an alleyway in the corner of her vision. The end of the alley is a sharp turn towards the direction she's headed in. It looks to be an awfully convenient shortcut.
The fox traipses into the alley, and she's immediately hit with a strange smell. As she rounds the corner, she encounters an unusual sight: a hyena lady several feet taller than her and easily double the width is lounging on a discarded beach chair next to a dumpster. The strange woman is completely nude, her breasts with pierced nipples and cock the size of Melanie's forearm on full display.
"Nghuh?" Bertha looks up from where she lounges peacefully.
"Oh, sorry, miss, I, uh- geez, I didn't realize there was anyone here," Melanie says sheepishly, backing slowly away from her.
GRRRWWWLLLLLLLLLL
Bertha lumbers to her feet with a grunt and smiles a sharp-toothed, hungry smile. "Just as I 'as gettin' hungry," she says absently to herself, not responding to Melanie at all.
The massive hyena stomps forward and grabs Melanie as she turns to flee. It's an ungraceful, sweeping motion with both arms that pulls Melanie right up against the woman's flabby tummy.
"Mmphf! Lemme go!" Melanie yells, trying to push away from the hyena but finding herself unable to get her arms between herself and Bertha with her aggressor's vice grip.
"Hueheheh..." Bertha smiles down at Melanie, her one visible eye practically glowing with a sadistic delight.
Keeping a firm grasp on her victim with one hand, Bertha uses the other to push Melanie's face deep into the unwashed fur of her flabby belly.
The helpless fox girl squeals, but any attempt at making any real noise is muffled by the yeen's big belly. Tears well up in Melanie's eyes and are soaked into Bertha's fur instantly as she fails to put up any resistance against the much larger woman.
GWWRRRRRRRRRRRRR
Melanie feels something hot and wet drop onto the top of her head, then more running down into her hair. She renews her struggles as she feels Bertha drool onto her helpless form, but it does her no good. She's far too weak to escape.
With thick, heavy slobber still running down the sides of the defenseless girl's head, Bertha adjusts the hand she's gripping Melanie with to reach for her ass. She gropes the girl's left butt cheek firmly, causing Melanie to let out a muffled wail that, like her, can't escape from where the yeen holds her.
Bertha's cock tenses against Melanie's leg as it gets more and more erect, and the terrible realization dawns on the arctic fox that the yeen can do absolutely whatever she wants with her and that she almost certainly will. 
Melanie lets out a yelp as Bertha grips her tightly beneath the arms and hoists her up. The large yeen tosses the smaller fox onto the lid of the dumpster.
"Ow! What're-" Melanie tries to pick herself up from the dumpster, turning to look at what Bertha is doing now, only to find the fat, furry ass of the hyena lady looming over her.
SLAM
Bertha hops onto the dumpster, landing her rear end right on top of the helpless Melanie. She lets out a pleasured-sounding grunt as she begins rubbing her ass back and forth across the girl, who is overwhelmed easily by her weight.
Melanie gasps for breath beneath the large lady, a dull pain rippling through her body from being smushed between the lid and Bertha's behind. Between desperate breaths she tries to make some cry for help, but only a weak wail is able to escape her.
The arctic fox takes another breath at the wrong time, right as Bertha scoots her ass up to cover Melanie's face as well, and she gets a mouth full of thick, matted, unwashed fur and indescribable rear musk.
"Uah~ Huahh~ Yeah~ Hueheheh~" Bertha takes immense enjoyment in the whole ordeal as Melanie squirms weakly beneath her. 
The struggles from Melanie get slower and slower over time, though whether it's from her body trying to conserve what energy she has or her simply starting to give up, the yeen does not know. She doesn't particularly care, either.
Melanie's eyes are sealed closed tight, her hands balled into fists and clenched tightly as she strains to hold herself together. Her senses grow cloudy from the overwhelming sensations, the musk, the pressure, the pain, the violation. The poor fox's mind is sent reeling from it all.
CREEEAK GRRRCHNK CRASH
The lid of the dumpster groans and dents inward under the weight of the two on top of it until it can't take it any longer. 
It caves inward, causing a startled Bertha to hop off and an unfortunate Melanie to become caught with her arms and legs over the edges of it, barely hanging on to keep from falling in the garbage below.
Not wanting to let her food fall in the trash, Bertha grabs Melanie as she had before and lifts her up, giving her a big, goofy, yet sinister grin.
Melanie makes some vain attempt to struggle, to resist, to flail her arms or kick at Bertha's gut with her legs, but she's already become so battered she can barely move and with a mind so hazy she can barely comprehend what's happening to her.
Bertha turns her around, and Melanie has a vague idea of what's happening and what's about to happen, her thoughts clouded by a distance from reality caused by what Bertha has done to her thus far.
The big yeen presses Melanie up against the side of the broken-open dumpster, her breasts pressed up against it through the nice sweater she'd picked out of her wardrobe that morning and her head hanging limply over the edge of it.
Her panties are ripped clean off from under her skirt by her aggressor and discarded somewhere behind her, but Melanie hardly feels it, only giving a slight, reflexive jolt in response.
SLAM
The fox is briefly brought back to her senses by the full force of Bertha's cock ramming into her sex from behind. The powerful thrust jostles her not unlike being shaken awake from a nap.
SLAM
Bertha slams into her again, the overwhelming heft and strength of the hyena ramming into Melanie like a truck.
SLAM
With each thrust, Melanie's mind tunes it out like agonizing background noise, the pain and intensity and violation and airborne cocktail of horrible olfactory sensations causing her to mentally shut down as her only possible retreat. She grows more and more unresponsive as the yeen continues.
SLAM SPLAP WHAM
Bertha grunts and breathes heavily, a big cruel smile across her face as she fucks her newest toy and soon-to-be meal past her breaking point. 
The smaller fox's insides take a good amount of force to fit herself into with the size difference between them, but the way they squeeze her cock within makes it entirely worth it.
PLAP SLAP SLAM
The hyena feels the familiar rising sensation as she approaches orgasm. Melanie feels nothing.
Bertha slams into her helpless victim harder and harder, faster and faster, until
PLAP PLAP PLAP SBLRRFHSHGHLPRRT
She unleashes a thick, heavy load deep inside of Melanie, whose only reaction is a brief twitch. The yeen's semen pumps Melanie tremendously full, as if her giant cock hadn't filled her up more than enough already.
The sticky white stuff drips out of her onto the ground, landing in thick globs that splatter into puddles, trickling out faster in a torrent as Bertha pulls out of her and rests her cock against Melanie's back.
"Huff... Huff..." Bertha keeps holding Melanie against the dumpster, staring down at her hungrily in anticipation of what's to come.
Heavy drool trickles down Melanie's head, soaking her hair as her soon-to-be devourer basks in her appetizing appearance. And yet she remains almost completely limp and still.
Bertha prods her roughly, jabbing a finger into her cheek to see if she'll respond. She does not.
The hyena spins her 180 degrees around to face her. Melanie stumbles and does little more than hold herself up, staggered on her feet with a complete blankness behind her eyes.
"Greheheh~" Bertha waves her hand in front of Melanie's face a little, then faster, then accidentally smacks her on the side of her snout. Melanie doesn't react at all, not even a flinch. The girl simply stumbles to the side, regains her balance on uneasy footing, and stands back up limply.
Bertha makes what would be a giggle if her voice were a bit higher but really comes out as more of a guttural chuckle. She gets up behind Melanie and gives her a hearty shove, and Melanie stumbles forward, barely catching herself, then becomes still again, operating on reflex alone.
Bertha follows her and pushes her the other way, finding great amusement in shoving the helpless girl around. After a few shoves, Melanie fails to catch herself and drops to the ground like a ragdoll, landing hard on the concrete and skidding slightly.
Bertha howls with amusement watching her drop and walks over to pick her back up, not done with her yet. The yeen pulls her close and rubs her face into her gut, half smothering her with her unwashed belly fur and thick rolls of fat.
The hyena smiles and lets out a long, satisfied sigh watching Melanie limply allow herself to be violated in this way, the poor girl too broken to resist.
GRRRRWWWRRGRGGLLE
Deciding she's played with her food enough and with little else to do with a toy that doesn't react at all, Bertha finally decides it's time to put Melanie where she really belongs.
HOUMPHF- ULRKP GLURLP
Bertha engulfs Melanie's head in the same motion as she lifts the unresponsive girl up. In less than a second of ravenous devourment, the fox's entire upper body is stuffed into her maw and being pushed down her throat.
SLRRKPL GULRP HUUOOOOOORRRPHHHHF
In another couple moments, Melanie is completely gone, her bottom half disappearing just as quickly as her top half. The hyena lets out a tremendous belch, the natural result of eating so fervently.
Bertha devours her with such speed that if a passerby had been distracted for just one moment or a bus had passed in front of the two, they wouldn't have even witnessed it happen, just Melanie there one moment and gone the next.
GRRRRWWWLLLLL GRRRRRGGGGGGGLLLLRRRG
Bertha lets out a satisfied sigh and sits down with her back to the dumpster, her gut larger now, though not by much on account of how large she and her belly already were.
She breathes heavy as she leans over her gut and rubs it with both hands, massaging her acids into Melanie's deteriorating body. The fox trapped inside begins to squirm again, though only on natural reflexes, neurons firing and creating kicks and twitches and jolts in her body's last futile effort toward self-preservation.
GLORP GLLRRRGGGGGG CHURRRRRN
The struggles don't last for long, however, the yeen's gut being well used to digesting meals far larger and tougher than Melanie could ever be. She gets no ceremonious last cry as her body fades away, no hopeless last words, not even anyone nearby to witness the occasion aside from the very pred she's forced to stew in. Still shut off from the violation of her assault prior, she doesn't even get to have any last thoughts, be they panicked or profound.
UUUUUUUUURRRRRRRRHPHFFFF
Bertha lets out another belch. She hardly has more going on in her head than Melanie does, frankly. She's full and has had her usual lust satiated, though, so fully literate or not, she's quite happy.
SMACK
The hyena slaps her gut, watching the skin ripple across the surface of her bloated belly, and she chuckles in amusement. Shortly thereafter, she feels a pressure in her bowels as Melanie is ready to leave, and not unlike an animal jumping from urge to urge without thought or consideration, she gets up to relieve herself.
Humph- CREAK-
Bertha clambers up the side of the dumpster and rests her ass over the broken-open lid. Perhaps it's a particularly cruel final resting place for the hopeful young woman she's about to dispose of, but to Bertha it's simply the most convenient place to do her business.
FBBLRRRBFRRLRLLLRT SPLAT BLRRRFBLLRLT SPBLBRRBLTRLFRRLT
Fat logs of brown filth press out from between Bertha's furry ass cheeks. One by one, they splatter on top of the garbage bags, food wrappers, and general residue of filth already residing inside.
Melanie's remains quickly form a mound that fills the dumpster almost completely, some of her leaking out over the sides and forming small pools of brown mush on the ground around it.
As soon as Bertha has fully voided her bowels, she hops off the dumpster and fans her nose with one hand, the stink of her latest bowel movement a bit much even for her. She takes a moment to turn and admire her handiwork before grabbing her beach chair and lumbering off to find somewhere else to squat that doesn't smell quite as bad.
Nearly an hour later, two women arrive at a familiar roadblock, a cheetah and a hare. They decide on the same shortcut through the alleyway that Melanie had taken prior.
"Would've been nice for Stacey to give us a route that wasn't under construction," the hare says, somewhat irritably. She takes a sip from a large plastic cup of soda, finding it to soon be empty.
"Yeah, well, guess she didn't realize there'd be road work today," the cheetah responds in a laid-back tone of voice.
"Well, maybe, but she could've checked," the hare says, noticing the dumpster out of the corner of her eye, "Hold on, I'm gonna go toss this cup."
"Alright," the cheetah responds, "Hey, is it just me or does something smell really-"
"EAUGH!" comes a cry from over by the dumpster, "What the fuck? That's disgusting. It looks like at least a dozen guys must've taken a shit in here!"
"What?" the other woman approaches cautiously, "Oh gross, some of it's even dripping down the side."
"Yeah, no kidding... Oh for FUCK'S SAKE-" the hare lifts one shoe from where she'd inadvertently stepped in Melanie when she'd approached the dumpster, "These were new shoes, too..."
The cheetah only sighs, "Come on, just toss the cup and let's go. I don't want to linger here and smell that any longer. Wipe off what you can on the ground as we walk and we'll rinse the rest off at Stacey's place. Melanie's probably been waiting on us for an hour now already anyway."
"Ugh, yeah, I guess..." the hare grumbles.
Both of them leave the alley behind, unknowingly leaving Melanie behind with it. All of Melanie that makes it to the gathering will be brought in on the bottom of her friend's shoe.
