"Thank you for agreeing to take care of my little boys!" the rabbit mother says as she stands in the doorway, "It's always so hard to find a sitter we can afford."
"Of course, ma'am, thanks for hiring me. I'm sure your boys will a pleasure," replies the fox she's hired, holding back a devious grin into a polite smile, "Have some fun tonight, you deserve it."
"Well thank you, I'll be back in a few hours," the mother says as she turns to leave, "See you then!"
James waves goodbye to her and turns to meet his prey, four little boys, all seven years of age, save for the smallest who's a year behind. Each one has delectable little ears sticking up from their head, big innocent eyes, twitching bunny noses, and soft white fur, perfect for staining brown.
"Hello, boys," he says, licking his chops, "I'm your new sitter. Why don't you introduce yourselves to me?"
"I'm Georgie," the first introduces himself.
"Oh- I'm Theo," the next says in turn.
"I'm Harold," says the next in line, before gesturing to the six-year-old beside him, "And this is Tommy. He doesn't talk much."
James crouches down slightly and bends over, smiling at the little boys, "Well it's lovely to meet you all. I'm sure we're all going to have a lot of fun tonight~" He stands back up and moves towards the hall, "Now how would you boys like to play a little game with me?"
"Huh? Sure," says Georgie.
"Uhm, okay," says Theo.
Harold objects, "I don't really want to play a game. I'd rather stay out here and read a book. Plus Tommy really doesn't like games."
James only smiles, "Well, we're going to play. Just for a minute, at least, then if you don't like it, you can go do something else. Alright?"
Harold sighs and takes a reluctant Tommy by the hand, "Well, alright."
The fox leads the four little boys down the hall and into their mother's room, where he closes the door behind them.
"This is Mom's room," Theo says, "We're uh, not supposed to play in-"
CLICK
James places a locking mechanism he'd brought along in his pocket onto the door, locking it up tight. "None of that matters now, boys~" he says with a sadistic twinge to his voice. He turns to face the children and pulls down his pants, letting his erection pop out and twitch in the open air.
The four boys all back away in fear as the sitter strips down, not sure what to make of it. James quickly reaches forward and grabs Tommy by the ears, lifting him off the ground. Harold gasps in despair, and Tommy squeals helplessly where he dangles.
"How about I make Tommy here the example?" James says, "You're all going to follow his lead."
BLORPT FBLRRT
The little boy, who'd already been twitching in fear just being brought along to the room, is unable to control himself in his terror. The back of his pants bulge out with shit as he soils himself, and James' cruel smile only grows wider.
James pulls the little bunny's soiled pants away and tosses them haphazardly on the floor. He then gets down on his hands and knees, holding little Tommy in place beneath him with one hand, and begins to thrust inside of him.
"Just like this," the sitter taunts, "You're all going to pleasure me~"
PLAP PLAP PLAP
Tommy shakes and cries as he feels the babysitter penetrate his tight, messy hole. James meanwhile smiles at the other three little boys, who have their backs pressed against the wall in terror. Harold especially looks away, holding his face in his hands in mingled fear and anguish.
PLAP PLAP PLAP
James lets his tongue lull outt of his mouth, sliding his cock into the quivering bunny's hole again and again, the soft, filthy texture of the boy's shit rubbing all over his shaft as he does so. The predatory fox finds himself lost in pleasure, slamming into the boy again and again and again, the soiled lubrication more than enough to make the little boy's ass into the perfect fuckhole.
PLAP PLAP PLAP
The babysitter continues to rape the little boy beneath him for several long minutes while drinking in the sight of his brothers frozen in fear and despair, unable to do anything to help him. His cock stiffens more inside of the boy's messy butt, and he lets out a slow, heavy exhale as he approaches orgasm.
"What happens next will make you wish you were out here being raped again," the fox says to the little bunny beneath him, "I'm making you into a nice, big load of shit soon~"
PLAP PLAP SPLRRRT
With one last, heavy slam, the sitter rams himself inside the boy's rear end and pumps it full of hot, sticky cum. He feels waves of pleasure shoot through his body each time his cock shoots another wad of spunk into the little boy's behind, cumming again and again for several long, blissful seconds.
SCHPLRFBT
Once his orgasm is finished, he pulls the boy off of his now-messy cock and holds him up, getting up onto his knees. "Now watch," he says, "Here's your fate~"
HOUMPHF- GLULP
James stuffs the boy ass-first into his maw, pushing his jaws open wide and stretching out the soft flesh of his mouth. With how small the child is, it only takes a little pushing down with his hands and a couple big gulps to swallow him whole, down into his eager gut.
GULP GLRRRRGGGGGLE
His belly bulges out with the child trapped inside, a desperate squirming mass distended from his abdomen. The three remaining boys watch in wide-eyed terror as Tommy struggles inside, imprints of his hands and feet appearing as he rubs against the walls of the stomach.
GRRRGGGLE CHURRN
Already getting hard again, the fox steps forward towards the remaining boys and grabs Harold by the arm. He pulls him close and rubs his face against his squirming belly with one hand. "Don't be too sad, I'll be reuniting you with your brother soon. You're going to make for one hell of a bowel movement," he says with a grin as he rubs his belly against the seven-year-old.
Harold squirms and attempts to push away from the cruel babysitter with his arms, but the fox outright ignores him, the boy held firmly in place with just a hand. With his other hand, James reaches for Georgie, and pulls him close as well, leaving only Theo behind.
He pushes Georgie to the ground beneath him and plants his ass down on top of the little boy.
GUUUUURRGGG GLORP SLOSH
James drops his gut down with himself as he gets to the ground, prompting harder squirms from its innocent occupant. His ass cheeks press around both sides of Georgie's face, his muzzle forced up against the babysitter's unwiped, filthy asshole. "The more you work your tongue on it, the longer it'll be before you join your brothers in my gut," he taunts.
While Georgie reluctantly begins to eat out the predatory fox in the name of self-preservation, James grabs Harold and pulls him over his belly, head-down. He grabs the little bunny boy's legs and pulls Harold's ass up to his muzzle while his head is pushed down to his shit-covered cock.
Once Harold is in position, he moves one hand down to the back of the boy's head and uses the other to hold his ass in place. He begins to force Harold's mouth over his cock while using two fingers to spread his cheeks.
SCHLK PLAP SHFLLT
The boy's ass is unwiped and dirtied with scat. "Heh, shouldn't a boy your age know how to wipe his butt?" the fox teases as he gives the filthy hole a sniff, "Well, I'll give you a lesson there when I wipe you off my ass tonight."
James begins to lick the little boy's ass, getting a good taste of it and occassionally slipping his tongue inside. Harold, meanwhile chokes and gags on the soiled cock being repeatedly forced down his throat. He makes his best effort to squirm, but all he really achieves is rubbing over his aggressor's belly.
GRRRRGGGGLE GLORP
Inside, little Tommy is only further compressed by the weight of Harold on top of him, the gurgling guts and bubbling acid around him begining to mercilessly work away at his soft, innocent body. His struggles grow weaker and weaker beneath his brother.
Beneath the fox, Georgie is utterly helplesss, his top half held firmly in place by James' ass and his bottom half held down by his gut. The taste and odor of shit overwhelms his senses, and any movement he tries to make is completely shut down by the babysitter on top of him. With each subtle movement of James' hips, his muzzle sinks deeper into his unwiped ass.
PLAP PLAP PLAP SPLRRT
Still hammering Harold's mouth over his cock again and again, James finally reaches that familiar, lovely feeling of climax. With one final hard push on the back of Harold's head, he begins to pump load after sticky load directly down the boy's throat.
The predator moans into the boy's ass as he shoots sticky streams of jizz down his gullet, until he finally pulls the boy away.
Harold sputters and coughs up cum that drips down his chin as the fox picks him up. "You know what happens now?" he asks. Harold only struggles and cries out uselessly. "You get to join your brother. Have fun churning into shit, bunny~"
HOUMPHF-
He stuffs the bunny's entire head into his maw at once, enveloping the little boy instantly.
GULP ULP UUUURPH
With just two gulps, he stomachs the violated child, sending him down to join his half-melted brother. As the familiar squirming sensation starts up again in full force, he looks up at Theo, still against the wall right in front of him.
GLRRGGLE GLRRFFF
"How rude of me to leave you out~" he says, grabbing the last brother and pulling him in close, "It's time for you to have some fun with your brothers."
"P-Please, no- Wh-what're you going to do to me?" the little boy cries in the fox's grasp.
James ignores the boy. He gently wedges his ass back and forth, prompting Georgie beneath him to let out a pathetic "Mmmphf!", and he leans back, his belly moving with him to cover less of Georgie.
"Alright, ass licker," he says, reaching around his gut to spread out Georgie's legs, "I want you to shit on the floor for me. Right now, push out a log."
Georgie attempts to squirm in protest and confusion, and he lets out another muffled noise.
"You're going to do it for me, or you're going up my shithole right now to join your bothers," the fox threatens.
A little, helpless grunt comes from beneath James, and afer a moment a small turd begins to press out of the little boy's backside.
FCCKRRKT BLRRFKT
The bunny boy finally pushes out a small brown mound onto the floor. James smiles, and his grip on Theo tightens.
SPCHLT
Wrapping his arms around his belly to pull it closer to him and keep it out of the way, he forces Theo to the ground with his face against Georgie's freshly-messed hole. The log he'd just dropped is smeared on the bottom of his chin and neck in the process, but James relents none.
"Now give his pucker a kiss~" James says, pushing the boy's face up against his brother's butt.
Theo struggles desperately to get away from the fox, but James' grip doesn't falter. There's no escape. His lips are forcefully pressed against his brother's hole, and James begins to run his hands over the boy while he drinks in what he's making him do.
James gropes the little boy for several minutes on-end as he's forced to get far closer than he'd like with his brother's messy butt. He doesn't announce when he's satisfied, he simply moves on to fulfilling his next desire by adjusting his seating once more and stuffing Georgie's head up his ass in the process.
SCHLLK
Georgie begins to squirm as hard as he can, accidentally kicking Theo in the shoulder as he does, but James has no mercy. He clenches and lifts up his ass just slightly then relaxes and slams it back down, again and again, gradually working the little bunny beneath him inside in the process.
Letting out a pleasured breath, he picks Theo up off the floor, his chin stained brown with Georgie's filth. "While I work your brother up my ass," he addresses the last bunny, "You're going to get me off one last time for tonight~"
James grabs the boy on both sides like an oversized fleshlight, and shoves his ass onto his still-erect cock. Theo begins to go limp in his grasp, sobbing, utterly defeated.
SCHLLFPH GLK PLAP PLAP PLAP GLRRRGLE
James is in heaven as he violates the two bunnies, Theo being slammed onto his cock as Georgie is forced through his shit-filled guts and presses hard on his prostate. All the while, Harold struggles inside of him, though he's beginning to grow soft and weak. Tommy has long stopped moving.
SCHLRRK SCGLRK FBLRFK PLAP PLAP PLAP
It takes several minutes for the whole of Georgie to disappear into James' anus, with one last slam on the ground making the bunny's soft feet vanish forever.
PLAP PLAP SPLRRRFBT
As he pushes Georgie the rest of the way up his ass, an intense spike of pleasure shoots through him, and he slams Theo hard onto his cock. He gushes into the last of the bunny brothers, letting out a pleasured exhalation and rolling his eyes back in his head as he does.
After reveling in the feeling for a moment, he finally pulls the little boy off his cock and licks his chops, "You know what happens now, don't you?"
Theo only quivers helplessly, and he offers no resistance as James devours him head-first.
GLULP ULP
He goes down just as quickly as the others, and he soon joins Georgie and what's left of Harold and Tommy inside the babysitter's stomach.
GWRRRRFFGLLRRRG GLRRFFG GLORRRP SLOSH
James gets up and clambers onto the mother's bed, lugging his squirming belly with him. He grabs a remote off the nightstand and turns on the TV on the wall of the room while letting the boys inside of him digest.
GLRRRRGLE LRRRG GWRRRRRFG GURRRRRGGLE CHURRRRRN
As he lounges, his gurgling gut provides just as much entertainment as the TV. Inside his belly, the boys who haven't already turned to soup squirm and writhe, imprints of hands and feet and faces briefly appearing as they desperately struggle, with no chance of actual escape.
He relaxes, satisfied with his handiwork, for a couple long, relaxing hours in this way. The struggling slows to an eventual stop over time, but even still the gurgles and churnings of his gut as it processes what's left of the boys into shit is more than enough to satisfy him.
GLRFFG GLORLP BLRRRGGGGG
As what's left of the boys reaches James' colon, he sees out the window a pair of headlights approaching the home. Their mother is finally returning home.
PAT SLORSH
He smacks his bloated gut, "Well boys, looks like it's time to drop you off."
The fox scoots back to the head of the bed and spreads his legs wide.
FBLRRRRRRRBLLRRT BLRRBLT PFRRRT SPLTLTRTLT
A slue of soft, brown shit pushes out of his ass onto the previously clean sheets. A skull from one of the boys slides out in the slurry, and as James pushes harder, a mess of mingled vertebrae from all four boys flies out of him, small pieces of little bunny spine speckling the mess and splashing filth further over the bed and James himself.
BLRRFFBLLRRT FBLRRRBLLT SPLRRRCH SPLAT
With another heavy load of what used to be a certain mother's much-loved little ones, he pushes out a pelvis, followed by several femurs. A mess of phalanges and carpal bones that used to be a child's hand slides out of his ass into the growing mound on the bed.
FBLRRBLRRT BLRRBLRRT BLORPT PLRRT
The babysitter lets out a labored exhale as his gut shrinks and shrinks, the mass of the four little ones that previously filled his gut now piling onto their mother's bed.
The mess of shit and bones continues to press out of him, until finally with one last push the remaining three skulls pop out of his ass one by one, embedding themselves into the messy pile. He hears the jingling of keys and the turning of a lock at the front door.
James maneuvers around the mess he's made of the boys, some of the shit covering his ass being wiped off onto the bed sheets, and gets up from the bed-turned-toilet. He stretches and puts his clothes back on, then goes to greet the arriving mother.
"Hello, madam," he says politely as she enters the living room, "How was your night out?"
"Oh, it was wonderful!" the mother says with a smile, "Were my boys good for you?"
"They were an absolute pleasure~" the babysitter says with a smile, "I actually just put them to bed."
"That's lovely, thank you," she replies, pulling out her wallet to hand the fox his pay. As she hands over the bills, her nose twitches, and she remarks, a little sheepishly as she doesn't intend to be rude, "Do you smell something foul? Or is that just me?"
"Hm? I'm sure it's nothing," the sitter waves it off, "Now I best get going. Have a nice night!"
"Er- you, too," the mother says, rubbing the back of her neck as the fox leaves the home in a hurry.
James makes his way to his car to head home, smiling contently with his deed. As he opens the driver's side door and clambers in, he hears the mother's shriek coming from inside the house. 
Looks like she won't be needing babysitting services again any time soon, but she may have to call a cleaner.
