Helpless Babysitter

Sheldon hummed quietly as he laid belly down in the middle of his bedroom, his legs idly kicking in the air and his tail wagging lazily while he played with his action figures, the young fox's whiskers twitching as he slammed the toys together, a grand action scene playing out in his head. The nine year old kit was only pulled out of his fantasy world by the sound of his mother shouting up into his room, 
"Sheldon, come out here for a moment, would you sweetie?" 
Pushing himself up, the canine ran out and down the stairs, still humming the song stuck in his head, leaning down over the railing to talk to his mom,
"Yeah?" 
"Sheldon, could you watch over Brian and Tommy for a little bit? Shouldn't be more than an hour, maybe two. I promised their parents that I'd keep an eye on them for this evening, but I just got a call from my bank and I need to pop over for a quick visit there."
Sheldon instantly frowned at the thought of having to babysit the two boys, having had ample experience of it in the past. Though the pair were a handful of years younger than him, they were also rather rowdy, quick to stir up trouble at a moment's notice. The cub's hesitation was evident from the disgruntled look on his face as he hummed and hawed, thinking about the perfectly peaceful Saturday afternoon that would most likely be wasted on having to chase around a duo of unruly pups if he said yes, his mother sweetening the deal after seeing his doubts, 
"I'll order in pizza tonight if you help me~" 
Sighing, Sheldon finally gave in and nodded, getting a grateful kiss on his forehead from his mom as she smiled and patted him on the cheek, 
"That's my boy~! I'll go over and fetch the cubs over now before I've got to leave."
The fox watched his mother stepping out and going over to both of their neighbours to grab up the kids in need of a babysitter, instantly starting to regret his decision as he already began hearing some hooting and hollering coming from the first house that she walked over to. Sheldon suddenly remembered what he'd left sitting out in the open, quickly dashing upstairs and into his room, looking around before spotting a box of suppositories on his writing desk. He shoved the small box into one of the drawers, not wanting the visiting puppies to see the slightly humiliating way he had to take his nightly medication with the help of his mom, wiping his brow and sighing in relief at having remembered to stash his embarrassing secrets away before it was too late, hoping that the nosy kids wouldn't turn over his bedroom like the last time around they were over. 

A few minutes after she left, Sheldon's mother returned with the two visitors in tow, the pair immediately running into the house and chasing each other around the living room, screaming and giggling as the young fox watched from the stairs with a worried look. The first of the dogs was the six year old shiba Brian, his coat a light cream colour, his tail curling up to his back as he clambered over the sofa to leap at his friend, missing and stumbling face first into the rug, quickly bouncing back up to his feet with a laugh. The second cub in need of babysitting was a dalmatian named Tommy, nearly just as big as the shiba even though he was about a year younger than Brian, his long tail almost tripping him over as he peeked over his shoulder while sprinting around the living room. The neighbourhood was a very close knit one, which meant that kids from many different neighbours were often looked after by one of them, meaning that Sheldon had spent an unfortunate amount of time cooped up with the rowdy pair. The mother laughed lightly as she held up her hands, trying to get the unruly kids to calm down at least a little, 
"Alright, c'mon now you two, cool it down. I'll have to go to the city for a little bit, but Sheldon will look over you two until I get back. Remember to listen to him!" 
The two dogs quieted down and sat down, seemingly willing to actually listen to commands for once in their lives. The kit was almost feeling hopeful for the evening until his mom turned her back to pick up her purse, the two pups immediately leaning in close to whisper and giggle while they stared at the little fox on the stairs with malicious stares, his carefully optimistic smile quickly turning more sour. His mom rifled through her purse for a moment before stepping back over to the front door, waving to her son and the puppies with a smile, 
"Alright, I'll be back in an hour, you all behave until then!" 
Sheldon squeaked out a goodbye, almost wanting to yell out for her to stop, gulping as the door clicked shut behind her. He turned to look back at the two dogs, sighing as they were already scheming up something, only staying put for a few seconds before jumping off of the sofa and resuming their destructive chase. 

Sheldon did his best to curb the chaos caused by the two cubs, trying to at least corral the destruction into just one room, his suggestions for something slightly less riotous to do completely ignored by the duo until he finally mentioned going upstairs to his room to play with something. Brian immediately perked up, 
"Oh, I wanna play house! C'mon!" 
Barely able to keep up, the fox followed the pair upstairs and into his room, slightly out of breath as he sighed, 
"Alright, w… we can do that I guess, wh-" 
Before he was finished, the cubs were already ransacking through the closets in his room, the dalmatian peeking into a bag containing all of the baby gear and toys that Sheldon's parents had put away once he was old enough to not need it anymore. In the bag were a few leftover diapers, the dog pulling one out and tossing it at the kit, 
"You're gonna be the baby, and we're gonna be the parents!" 
"What, I'm not gonna p-" 
The shiba gave him a push from behind, 
"Put on the diaper already, baby!" 
Knowing better than to try to argue, Sheldon rolled his eyes and folded open the diaper to put it on over his shorts, getting a disapproving shake from Tommy, 
"No, you don't wear diapers over your clothes! You gotta get nakey first~!" 
Groaning, the fox thought about it for a few seconds, the pups' incessant chanting and screaming finally breaking him, his cheeks glowing red as he pulled off his shirt and dropped his pants, hesitating for a few seconds before taking off his briefs as well. Trying to cup his crotch, he looked at the shiba as Brian snatched the diaper from his hands, tapping a blanket that the other boy had set down on the floor, 
"Alright, now lay down so I can put it on you~!" 
Already deeply regretting his choice in getting mixed up with the two younger canines, the kit stalled for a moment before laying down on his back, still cupping his sheath and pushing his thighs together, blushing as he looked away from the giggling kids. 

The fox tried to stay calm as he watched the dogs, his eyes going wide in horror as the two suddenly started stripping down as well, 
"Hey! What the heck are you doing, stop!" 
The kit tried to sit up, but was quickly stopped by the dalmatian putting a foot on his belly, the pair both grinning down at him while tossing off their shirts and pants, 
"Didn't your daddy ever change your diapers like this~?" 
The now naked Brian knelt down behind the confused canine, grabbing Sheldon's legs and pulling his knees up against his chest, leaving his flank completely exposed. The shiba's knotted member slowly wriggled out of his sheath as he peeked down at his babysitter's tailhole, snickering as he stuck his tip against the pucker. The feel of the hard and hot shaft poking at his entrance made Sheldon wriggle around at twice the intensity, the dalmatian sitting down on top of him to keep him pinned down as he shouted, 
"Stop, I don't wanna play this anymore!" 
Gripping his growing knot, Brian shrugged, 
"You're just a li'l baby, you don't get to decide!" 
He rammed into the fox's ass, both boys grinning at the sound of Sheldon's sharp shriek as his cock pulled open the tight hole, sinking in all the way down to his knot. Staying balls deep, the cub let his babysitter's quivering pucker massage his shaft, the growing knot gaping the kit wider and wider by the second as Sheldon broke down in hysterics, fighting back tears. The shiba looked at his red knot stretching the tailhole, the older boy's donut pulsing as he gently shoved his hips back and forth, watching in amazement, 
"Dude, it's getting so wide! Look for something to plug him up with!" 
Leaving his friend to hold down Sheldon, Tommy dashed over to search the room for something to use as a plug, tossing aside some pens and figurines until he opened one particular drawer, pulling out the box of suppositories that had been stashed there, holding it up in the air as both kids laughed mercilessly. Sheldon covered up his face in shame as the dalmatian tossed the box onto his belly, Brian quickly snatching it up and pulling one out, 
"I guess that's why you can take my thingy so easily, you're really used to buttstuff!" 
Holding a suppository in one hand and gripping the base of his cock with the other, the shiba yanked hard, slowly making his knot slide out while Sheldon squealed, a few tears wetting the kit's cheeks. Brian finally managed to pop free of the tailhole, quickly shoving up the smooth and sizable pill into the opening to plug it up, giggling as his dick squirted a few threads of precum all over the fox's thighs as he stroked it. Grinding his dick against the kit's soft undercarriage, pent up from the stretching he'd done, it didn't take the shiba more than a few quick pumps to splatter his babysitter's belly and ass with his seed, soaking the orange fur with thick strands of cum as he moaned, his tail wagging the entire time as he squeezed out every drop he could, his other hand still shoving in the suppository deeper. 

Grinding his teeth together and whimpering as the dog's finger pushed the pill into his clenched tailhole, his crotch completely coated in cum and a sticky mess running down his asscrack, Sheldon tried to mop away his tears before anyone saw, hopelessly wiping at his eyes as more flowed down. After making sure that the big pill was in nice and deep, taking a few deep breaths as he cleaned his cum-covered fingers on Sheldon's chest, Brian grinned and grabbed the diaper he had at the ready, sliding it underneath the fox's ass and taping it up, letting the padding soak up his sperm. With his sheath and flank squeezed inside of the tight confines of the diaper, colourful pictures of flowers and hearts adorning it, the kit was rolled over onto his belly, groaning as his head was shoved against the blanket and his backside pulled up by the tail. Getting worked up after watching his friend stuff the babysitter's tailhole and blow a load over the fox, Tommy couldn't keep his hands away from his own red rocket, fondling himself as he ogled Sheldon's plump ass wriggling in the air in front of him. His eyes moved to the other end of the older boy, a devious glint in his eyes as he stepped in front of the fox, gripping his cock and letting a few drops of pre drizzle down onto the kit's face and head, 
"I think it's time for the baby to have his dinner. Here's your bottle, drink up~!" 
The dalmatian squatted down and grabbed Sheldon by the scruff of his neck, yanking his muzzle into the dog's crotch, rubbing his nose against Tommy's taut ballsack as he whined, the suppository in his asshole and the wetness in his diapers making every shift an uncomfortable one. 

The dalmatian humped his dick against his babysitter's face, panting with a blissful look as his tip sprayed a near constant stream of precum all over the kit's head. Having had enough of the foreplay and the teasing, Tommy hooked two fingers into the corners of Sheldon's maw, pulling the muzzle open and planting his cock deep inside, even getting his knot into the mouth with a little bit of wriggling and shifting around, his tail sweeping the floor in excitement. Sheldon instantly gagged at the hard shaft ramming down his throat, trying to pull away with very little success, constantly yanked forwards by the spotted pup in front of him and shoved from behind by the shiba. His claws dug into the blanket as his streaming eyes squeezed shut, his maw forced around the entirety of the little boy's surprisingly large girth, his cheeks bulging out as the growing knot locked the cock inside of his muzzle. Tommy ploughed into the kit, leaning over the fox and moaning out loud as he thumped the babysitter's face with reckless abandon, thrusting back and forth as fast as he could, his tongue hanging out of his own mouth as his eyes rolled back. Sheldon could feel himself gradually losing control of his own body, pushed to the edge by the stiff cock choking him and the puppy behind him fondling his ass, his barely audible sobs hidden underneath the coughs and the slaps as the dalmatian drilled his throat. Pulling at the fox's ears, Tommy howled in ecstasy as his entire pole twitched hard, bearing down and going still for just a second before shivering from tail to nose, resuming his humping twice as hard as a huge torrent of cum erupted from his cock and blocked out Sheldon's airway, his bucks ramming down his load deeper into the babysitter's throat whether the kit wanted to swallow it or not. 

Choking on the dalmatian's cum, nearly passing out, Sheldon strained hard enough to accidentally void his bowels in the process, a loud gurgling sound coming both from his throat as well as his backside as his tailhole spit out the suppository, a mudslide following close behind. With the shame on his cheeks only getting worse, his diaper bulged out and began to sag, the bright white slowly taking on a more brown colour as the mess continued gushing out of his abused hole, having lost all control of his bowels. Both puppies laughed and groaned in disgust at the same time, Brian putting a paw over his nose as he swatted the air, 
"What a bad little baby!" 
He put a hand against the still-expanding diaper, feeling the warm shit sloshing around inside as he gave it a slight squeeze, suddenly pulling his arm back and slapping it back down as hard as he could. Though the padding and scat softened the impact slightly, Sheldon still flinched at the spank, his squeal muffled by the throbbing shaft in his throat as another hard slap landed on his ass, smashing the diaper and sending a torrent of brown sludge down his legs. Tommy managed to get his knot free of the kit's maw, pulling out and letting cum and spittle drip off his length and onto the whimpering fox's face as he stood up, moving behind the crying babysitter and getting a few spanks in on the boy's flank as well, using his foot to smack the ballooning diaper as both pups giggled. Hearing the front door opening up, the pair quickly dashed off to hide as Sheldon's mom walked up the steps, 
"Sheldon, honey? Are you in your room, did y-" 
She pushed the door open to see her son lying on the floor, curled up with cum pouring from his nose and shit smeared across his thighs, a diaper filled to the brim strapped to his sore ass, tears flowing from his eyes.
