Daycare Accident

Dashing along as he giggled, Alex ran after his best friend, trying to grab onto the raccoon's bushy tail as both of the boys raced around the fenced in yard of the daycare, coming close to catching the other cub several times but always tripping at the very last second, though none of the tumbles onto the soft grass lessened the smile on the five year old kid's face. In the bright sunshine, the golden retriever truly lived up to the name, his soft blond fur glimmering gently, his white belly mostly hidden underneath a t-shirt and a pair of denim overalls held up by suspenders, his golden red eyes filled with joy as his floppy ears flailed all around. Though the cub was as warm and approachable as a kid his age ever could be, he still mostly just played with his best friend, needing some extra time to get over his shyness whenever meeting anyone new. Among the people that the boy trusted without question was the daycare worker that was watching him as he played in the yard, spotting the tall whitetail deer leaning against a wall, the man's piercing green eyes staring at him as he smiled and waved, 
"Hey, Mr. Scott!"
Scott smiled and waved back at the cub, seeming entirely innocent at a glance as he stared at all of the kids in the yard, though his eyes kept continuously straying back to Alex. Peering closely, the deer could just barely make out a slight hump in the boy's pants, the pair of overalls bulging slightly more at the rear than all of the other pups, with the extra padding showing particularly clearly whenever the golden retriever stopped and bent over to examine some colourful bug or a particularly interesting rock on the ground. Scott knew that the boy was still in pull up diapers, unlike most of his peers, making the deer grin subtly as his thoughts strayed further away from the innocent territories and towards the taboo, having to lean forwards over the railing of the daycare's porch to hide the slight lump in his own pants, not wanting to field any awkward questions from any of the overly inquisitive kids as he continued spectating the little dog's playtime. 

Running around the yard, his every step accompanied by the barely audible crinkle of his pull ups that he'd already learned to tune out, Alex didn't pay much attention to the rumbling in his belly, all of the jumping and skipping around jostling the cub's heavy breakfast. The cheerful boy ignored the twisting in his gut all the way until it became too great for him to just push aside, slowing down to a stagger as he groaned and held his belly, his wagging tail quickly flopping down between his legs as he bit his lip and doubled over slightly. Alex had been hoping that the rumbling in his belly might've just been some gas, and that he wouldn't need to cut his yard time short to go sit on a potty and be bored, but his hopes were quickly proven incorrect as his situation turned dire. The growing pressure pushing against his clenched pucker suddenly increased tenfold as the pup froze in place, whimpering under his breath as he grimaced, realising that even taking a single step might be too much and cause the dam to burst, but at the same time doing nothing would also ensure a catastrophe sooner rather than later. Trying not to move an inch, the golden retriever blushed as other kids ran around him, almost knocking him over as he glanced towards the daycare, the yard separating him and the bathrooms inside now seeming much bigger than before. Holding his breath, Alex took a shaky step towards his salvation, waddling carefully as he did his best to keep his tailhole sealed shut, one hand propped against his rear to push his ass cheeks together in a vain attempt to delay the inevitable. The pup only made it about halfway through the yard before the pressure simply grew too great for him to hold back, his whining getting slightly louder as his knees buckled, a look of simultaneous shame and deep relief washing over his face as he squatted down slightly, burying his head in his hands. The rumbling in his belly grew worse before turning into toots and splurts coming from his pants, the diaper tightening as it was filled with the boy's poop, warming his backside as his suspenders flexed slightly to hold up the plumpening pull ups. As soon as the first squirt had made it past his clenched donut, the little canine couldn't contain himself, giving up all hope and letting the rest of the stinky load stream out in one big stream, moaning quietly as the mudslide pushed smoothly from his asshole and filled up his padding, his tail curling underneath him to try to hide the mess. 

Having stepped inside for just a minute to sort out a situation with a lost teddy bear, Scott returned to the yard to see Alex squatting down in the middle of it, the boy's face red and his hands covering his eyes in embarrassment, still grunting softly as he emptied the rest of his belly into his pull ups. Walking closer, the deer didn't have to wonder what was going on for long, his nose confirming the extent of the situation as soon as he was within spitting distance of the puppy. Alex peeked out from behind his fingers to see the man standing above him, the adult's hands at his hips as he tutted with a slight smirk on his lips,
"Alex, you didn't make a mess in your pants again, did you?" 
"N… no…" 
"C'mon, big boy, you're too old for this kind of a thing~"
Chuckling, Scott knelt down next to the cub, glancing around the yard for a split second to make sure no other adults were anywhere nearby before putting a hand on Alex's rear, giving the pup's butt a gentle fondle as his pants began to tent, feeling the mess inside squishing under his fingers as he huffed, 
"Well… nothing more to it, we've gotta get you out of those dirty diapers and changed into a fresh pair, don't we~?" 
Alex could only give a shy nod as the man's hand patted his back, staying on his shoulder as he was led into the daycare, walking with an awkward and stilted shuffle as he tried not to think about the feel of the steaming mass squishing around in his pants, still groaning and whimpering with every other step, only blushing harder as the man gave him a playful scolding, 
"Big kids like you should know better than this, Alex~" 

Scott walked the boy into the daycare and to the staff bathroom near the back of the building, patiently letting the waddling puppy walk beside him as he kept his eyes mostly glued to the bulging rear of the kid, trying not to salivate too much as he slipped a hand into his pockets, stealthily massaging at his growing erection through his pants. The staff bathroom was a fair bit smaller than the primary one, with just a single slightly cramped room instead of the row of bathroom stalls found in the other one. It did however have a diaper changing station bolted onto the wall, with the intent that the out of the way bathroom would offer more privacy for the cubs in need of a change. It also offered Scott more privacy for what he had planned for the boy, his wide grin only growing bigger as he gently nudged the little golden retriever inside, locking the door behind them both after making sure there wasn't anyone nearby, 
"Now, let's get you up here~" 
The deer opened up the diaper changing station, letting the table swing down before grabbing Alex under his armpits, lifting him to sit up on the table. Having gone through more than his fair share of diaper changes before, the cub didn't have any reason to be alarmed as he was pushed onto his back, his suspenders undone and his overalls carefully shoved down, exposing his filled pull ups, 
"Oh, what a stinky boy~" 
Alex only began to suspect something when the deer suddenly rolled up his shirt as well, exposing his belly and chest, leading him to squirm lightly on the changing table as the man's fingers caressed his soft fur, tickling him. The trusting pup didn't question the adult's actions for long however, assuming that Scott was just getting his shirt out of the way just to make sure it wouldn't get messy, trying to relax as best as he could as he stared up at the ceiling, shivering slightly as the buck's fingertips traced down past his belly button.

Glancing over his shoulder one last time to make sure the door was locked, Scott slipped a hand down to his crotch and zipped his fly open, pulling out his cock and letting it rest against the side of the changing table as he loomed over the half-nude cub, gently grinding his tip on the boy's legs as he grabbed onto the soiled diaper. Carefully pulling the pair down, the deer made sure that Alex could see his exaggerated reactions as he pinched his nose and wafted the air, grabbing a box of wet wipes from a shelf nearby, 
"You really do need to start learning how to go to the potty by yourself."
The cub tried to avoid the man's eyes out of shame, staring away as the deer pulled his diaper off completely before grabbing his ankles and pointing his legs up towards the ceiling, gingerly wiping at his rear until every smudge of brown was gone from his golden fur. The pup thought that Scott might've been spending a weirdly long time cleaning him up, squirming around uncomfortably on the changing table as the wet wipes rubbed at his ass cheeks, breathing a slight sigh of relief as he watched the last wipe being tossed off into the trash can. Scott however had no intention of stopping, even if the little boy's rear was sparkling clean, keeping Alex's legs up as he pulled the golden retriever's cheeks open with his other hand, letting his leaky tip poke at the soft buns as he smirked, 
"Whoops, I think I might've missed a spot here~" 
The buck put away the wet wipes and instead reached for a bottle of lotion from the same shelf, squirting a glob of it onto his fingers and rubbing it all along the puppy's ass crack, massaging the slick cream onto Alex's taut tailhole as the kid began moaning. Unsure of what exactly was happening, the golden retriever tried to stay still and calm, his high pitched groans getting worse as the man's finger pushed harder against his pucker, blurting out a sharp squeak the moment his hole opened up for the deer's digit. Wanting his perversions to remain under wraps, Scott rolled the boy over to his side, keeping the tip of the finger in his asshole while grabbing a pacifier from the shelf, shoving it into Alex's maw to help him quiet down, 
"Here, you can suck on this since you haven't grown out of diapers yet~" 

With a pacifier stuffed in his muzzle and a finger stuffed in his rear, Alex hugged his knees and groaned as his tailhole was stretched open, grimacing and biting into the rubber nipple as the man began twisting and thrusting the digit around, preparing his asshole for an even bigger insertion. Moaning with barely held back lust as the boy's tight pucker pulsed around the base of his finger, Scott poured another generous glob of lotion from the bottle, slathering his cock with the makeshift lube as he salivated, giving Alex's rear a few hard final pokes with his finger before pulling out, keeping the pup's ass cheeks separated as he watched the hole winking and slowly flexing closed. Like a hungry beast, the stag jumped on the cub, stroking and petting the dog's back as he pushed his shaft to the half-gaped hole, shaking in anticipation as his tip hovered at the entrance, 
"Just relax, this'll feel really good~" 
With his knees pressed against his chest, Alex closed his eyes and whimpered with the pacifier in his mouth as the adult pushed inside of him, stealing his virginity on a diaper changing table. He let out a strained groan as more and more of the deer's cock was buried in his tailhole, chewing on the pacifier and wriggling around, held gently but firmly in place by the panting man,
"Calm down, or I'll have to use the straps on this table and tie you up~" 
Whenever Alex thought that he'd finally taken the entirety of the buck's length in his rear, Scott always somehow seemed to find a few more inches to pack inside of him, leaving him huffing and puffing until eventually the girth was all in place, buried up to the hilt. The man made sure to stay bottomed out for some time, letting the boy adjust to his size as he panted and pet the cub's head, enjoying the tight hole hugging his curves. Unable to hold himself back for any longer, Scott eventually began ploughing the pup's bottom, one hand holding down the golden retriever and the other keeping the kid's tail out of the way as he hammered at Alex's ass, making the entire changing table shake and rattle around. 

Even with the pacifier clenched between his teeth, Alex's moans were still filling the small bathroom, his hands grasping for anything he could hold on to as he tried to endure the breeding, timing his inhales and exhales with the thrusts he was receiving. Though he had just emptied his bowels, the puppy had just barely been able to control his equally full bladder, but the anal pounding from the stag was certainly making it quite difficult to keep it up. Every slam from Scott put more pressure against his bladder, and his concentration was likewise weakening by the second, leaving him trembling as he tried to desperately keep from wetting himself in addition to the first accident. Unfortunately for the boy, he was fighting a losing battle, a particularly hard thrust finally making him lose control, whimpering as his little sheath suddenly erupted in a golden shower, most of the musky stream quickly getting soaked up by his own fur. The sight of the pool of urine growing under Alex, as well as the potent stink of it, was enough for Scott to finish, slamming balls deep and shooting a huge load deep in the little boy's belly as bellowed, grunting like a feral animal while the canine whined. Even after emptying his balls in the cub, the deer wasn't quite done yet however, a winded smirk on his face as he watched Alex's stream of pee slowly dying off, 
"L… look at what a mess you've made, and just after I cleaned you up as well. Well, if you think you can just take a tinkle anywhere you want, then so can I~" 
Alex felt the hot rush of cum quickly followed by another wave of liquid, moaning hard enough for the pacifier to drop from his lips as the stag filled his tailhole with piss, a mixture of cum and urine dribbling from his plugged hole as the man sighed in deep relief. Scott pulled out midway through his leak, aiming his stream up and soaking the cub's fur in his pee as the rest of it gushed out from the golden retriever's rear, marking the boy with his musk. 

Shaking the last few drops of piss from his cock before tucking it away, the deer stepped back to admire the messy and gasping canine for a moment before getting to work on the cleanup, drying the cub's fur with the help of some paper towel. In the end, Alex's fur was still a slightly more golden tint of yellow than usual, and he still reeked of the buck's musk, but at least he wasn't soaking wet anymore. Scott was just about to let the boy finally leave, when he had one final thought, reaching into the trash can at his feet and digging through it until he found a filled diaper from one of the other kids, still warm and brimming with shit. Pinned down and forced to wear the used diaper, Alex shivered as he felt it being taped on around his crotch, his ass sinking into the mud-filled padding as the man laughed, quickly pulling on only his shirt, setting him down and opening the door for him, 
"Alright, we're all done here, you can run off to play with your friends now~" 
Scott gave the cub a pat on the rear, watching the filled diaper smushing as the boy squeaked and awkwardly waddled away, his face flushed as he felt the heavy diaper jiggling around, rubbing on his sore ass as he frowned, feeling the other kids staring at him the moment he stepped outside once more.
