"Thank you so much for coming, mister Legoshi." The towering goat lady began, closing the front door behind her. "I'm going for an important meeting at school and I don't have anyone to look over my sweet little Asriel..."
"Er... Right." The Grey wolf replied, shuffling somewhat awkwardly.
He was aware of the fact this single Mother had contacted him as a babysitter recommendation, after meeting during a drama class involving teenagers learning how to properly perform on stage. They had gotten quite close ever since, and Legoshi felt a bubbling amount of flusteredness deep inside him when he'd found out that he was gonna look over the child. But he couldn't stop staring at her sizeable rear at the same time, and it was hard enough not to just stand there ogling the woman every time they'd met up. Ironically, his butt had seemed to develop a bit more than usual lately, too, adding an extra thickness to his usually very flat bum.
"So, I'll leave you two alone. Just don't let him eat you alive, alright?" She kissed his cheek before departing, her bubbly butt bouncing when she trotted out, while Legoshi stared at the closing door with a visible blush, flabbergasted at her words. As the Babysitter proceeded through the big house to hunt his charge, one big step sounded at a time, it was clear the woman had a habit of making extremely complicated puzzles; It took him multiple minutes to locate the kid, who was standing in his room with a big, stupid grin. Legoshi's enormous butt filled most of his trousers up, to the point where he was positive the waistband was starting to dig into the boy's huge cheeks. It had to be true, right? No way he could just ignore the constant bulging his butt did to his clothing. It always felt tight, especially across the plump, yet toned glutes. And thus, he shook off those thoughts as he stood in the doorway, watching the young goat for a moment.
"Hey. I'm your new babysitter. My name's Lego-"
"Ya smell."
The Wolf flinched in surprise, blinking in confusion. Shouldn't the offspring of the nicest goat in the world be slightly less grating? He looked at the kid, observing him. Pale white and slender, well-dressed with fur as shiny as his tiny pearly horns. If only his personality matched his looks, in turn!
"W-What?!"
"Like a wet dog. Anyway, I'm off to play some video games. You may want to do something similar if ya know what I mean."
Asriel made a gesture with his hands, glancing over his shoulder, and the grey wolf was left perplexed, eyes squinting slightly. What was he trying to suggest with his gestures? That he should lie down and maybe take a nap? The Grey Canine sighed and rubbed his head. Maybe he was reading too deeply into things.
"Oh, one more thing. You'll not survive the dawn..." The fairly shorter child hit the wolf with his shoulder while walking past him. Completely shocked by the weird statement, he stumbled forward, holding his arm, and was left in a state of sheer confusion. Why did the kiddo say such a... rather disturbing thing? Was the child feeling hostile, angry, threatened, or...? Shrugging it off, the canine decided to follow the insolent kid he was ordered to look after. Legoshi wouldn't stand such disobedience.
"Listen... Asriel, is it? I don't think I did anything to make you upset, so why don't we just start everything all over again, okay? The name's Le-
"I don't care. You're not the first babysitter I had, you know? And probably not the last one. So save the name for yourself because I don't want any attachments to body bags."
Was this happening? Bodybags? This was far above the kid's age, surely?! With utter shock and irritation written across his face, his back hunched, and his teeth visibly grinding, the larger creature approached the small goat, until the tips of their noses were mere inches apart. Before Legoshi could do anything, Asriel showed a sadistic grin with a mischievous glint in his eyes, before smacking the wolf's ass with a powerful strike.
"OUCH!"
Legoshi turned his back as a defense mechanism, rubbing his tailbone from the horrible sting. There was a wicked grin on the child's face, already savoring the feeling and sound. His butt, so round and meaty, had now a nice bright hand print on it. Oh, the ass was truly a remarkable prize. And by the way, his older bottom twitched, signifying the burning warmth radiating from the impact, he could easily tell how strong it was.
"Listen." He stated firmly with his usual monotone voice. "I will not tolerate disrespect from a, ugh, a damn child. Now do as I-AGGH!"
Suddenly, he ended up dropping on his knees, which caused his plump and round ass to re-emerge. Seizing this opportunity, the goat smacked his leathery orbs of fat as hard as possible. Slap, slap, slap. The boy was enjoying himself at the time, abusing his fluffy cheeks. The sensitive canines on his tail brushed against his huge bum, sending a wave of electroshocks across his nervous system. When finally done, Asriel observed the fruit of his labor. They were slowly gyrating back and forth in response to the painful abuse, wobbling around like jelly. The cute crack under his sore buttocks had already drawn a slick, noticeable line downwards, trickling slightly and reflecting the light seeping in through the windows. All the while, Legoshi was muttering to himself repeatedly, whining like a kicked puppy.
"Aww..."
The towering beast stood up, stopping Asriel's attacks. He could snap his neck in a second or throw the small body against the floor. But Legoshi was above the violence, so the only thing he did was wave his finger in his former charge's direction, chastising him with a scolding expression painted all over his face.
"You would be smart to remember I am here to ensure your protection."
"And I'm here to ensure you'll remember this day forever!"
Before Legoshi could react, Asriel was already behind the wolf, digging his paws into his pants and grasping the edges of the underwear. The goat pulled as hard as he could, and the pink, tight-fitting thong creaked and strained. In addition, it got pushed right into his slit, forming a sexy little cameltoe that would hide no secret about the shape, firmness, or density of his cock and balls. Pulling even harder, the clothes reached their maximum stretch capabilities, the air being forcibly squeezed out in between them. However, the cloth held strong, and with a couple of further tugs on his thin elastic layer, Legoshi closed his eyes as his bulge quickly shifted closer and closer to its final destination: the fabric began to glow white, the skin of his doughy, silky soft cushion getting crushed and devoured in the heat, leaving a trace of an odd, salty aroma. At that point, though, the material's surface was able to stretch no further.
"Are you serious? What kind of girly panties are those? Are you a queer or something? No, you're not. I saw you staring at my mom's arse. And speaking of asses, yours is so fucking gigantic, it's a wonder how you've managed to keep it hidden from everybody!"
Face reddening furiously, the wolf gritted his teeth together, desperate to prevent a full-blown-out yelling. It wouldn't do any good. He was told not to harm the child, but no one informed him about such verbal assault. He attempted to spin around once more, to gain whatever dignity he possibly could, hoping to face his foe with a brave expression... But as soon as he stepped onto his shoeless foot, his balance had already failed him, and he fell forward helplessly, arms stretched and knees scraping on the polished wooden surface of the hall. At the very last moment, a well-aimed leap prevented the animalistic instinct from taking control of his life, and he hastily pounced up and forth, his bulky and massive posterior jiggling loudly and threatening to tear the feeble fabrics open. Legoshi's hips made some circular motions, trying to push the uncomfortably sitting material down, but it was caught in a place it shouldn't be, in an awkward spot between his puffy lips. Then, suddenly, there came a quick flash of bright light, as Asriel hurried to shoot some pictures of the shameful accident.
"What are you--?"
But Asriel didn't finish, ripping the wolf's pants to expose the poor boy's long appendage, completely unfit for his large-sized testicles and meaty anaconda. But obviously, what had the most attention was his bare, exposed derrière, blushing in red, leaking, and a complete mess. Suddenly, there were the clicks of the camera, and just like that, Legoshi knew he would never be rid of those photos. Those nude, undignified, and vulnerable images. For a brief instant, he felt a rush of adrenaline surging through him, a desire to charge and beat the life out of the laughing and the photographing kiddo, that little goat abuser. But then, it would ruin his carefully maintained reputation. So, deep inside, he continued fuming in silence. Soon enough, the goat had enough, and dropped Legoshi's torn pants on the floor, exposing his humiliation for anybody to see.
"Delete those. Now."
"Why should I?"
"Do not make me mad. You're in big trouble and... what are you doing?"
Asriel furiously typed on his smartphone, ready to send the phone to several sites at once. The sadistic kid was more than delighted about the situation, his eyes filled with excitement and cruel, unspeakable ideas. By the looks of it, he was almost shaking with sheer passion and joy, craving more and more humiliating events. Of course, Legoshi had a feeling this kid could do as he pleased. 
"I'm one finger away from destroying your life. So, are you going to do what I say or do you want to start packing up your things? But either way, you can kiss your dignity goodbye."
Legoshi blinked, but eventually accepted his defeat. He couldn't believe he'd be bested by a child. A scrawny, defenseless, and adorable kid. Except this time, this ballbuster was anything but weak or innocent. Dropping his jaws in shame, he could tell his fate had been sealed, and since he couldn't lay a paw on the one responsible, he was completely at the brat's mercy.

*****

"This is so damn humiliating..."
Legoshi stood in Asriel's room, now wearing a baby diaper and frilly pink dress on top of his naked upper body. To his even bigger discontent, he was forced to carry a huge stuffed tiger, and forced to pretend it was his "kitty", and talk to it, looking all girly and adorably dumb. Legoshi was the same guy who tore through animals like paper, ending conflict without much effort. Just thinking of the strength those muscles and power they could show brought him happiness. Asriel fed him baby food which tasted funny and quite suspicious but had a somewhat pleasant spice. After filling his stomach, the kid undressed him and placed him in a bath filled with warm water, making sure to wash that massive butt at every chance. Thanks to his heightened sense, the wolf took extra details of his current condition, even the annoying smell.
"Now, time for you to dress up again!" Asriel cooed at Legoshi, caressing his butt lovingly and massaging it. The wolf couldn't complain or stop him, so Asriel decided to spank him one more time, hard and rough. Although Legoshi couldn't move, he immediately tensed up, hugging the "little" cub with a tight grip. After the spanking, Legoshi was dressed up again, this time with nothing underneath the shirt, sporting a nice white garment with a cute pattern. The diapers, thanks to their incredibly soft and absorbent material, left no crinkling sound or audible ruffling whenever he walked, and unlike cheaper ones, these didn't melt or warp over time. Naturally, as the diaper turned itself from white to partially brown, it shocked Legoshi in the process. He couldn't control his bowels! Did that brat put strong laxatives in his food?
"Someone needs a diaper change!"
Asriel pushed him onto the bed, forcefully removing his lower garments, and removing the used diaper, before powdering his drenched crotch. Next, came the butt wipe, brushing across his crack and taking away disgusting chunks of dirty matter. Even after shoving an entire roll of toilet paper in between his ass cheeks, the boy wasn't satisfied. Satisfied that there were no residues, the goat covered the sore butt with a thick coat of white lotion, spreading it evenly. He chuckled at Legoshi's soft dick since it got smaller than before.
"So tiny and cute!" The goat commented, before using baby oil on it, drying up everything, and coating the smooth slit with slime. Then he powdered Legoshi's massive and plump ass cheeks, rubbing some between the crack and placing the diaper underneath his balls. Like clockwork, he slapped it with a satisfying thud, smiling in pride.
"It'd be smart of you to remember who's in charge, though." With the threat implied, the boy threw Legoshi onto the bed, watching the muscular beast rest upon comfortable cushions and pillows, along with plushies shaped like cute critters. Even Legoshi, whose personal space was non-existent, found such a setup to be a bit too childish. Asriel took a picture book and with a wolf on his lap, they looked through it, giggling at memories and the antics he pulled.
"And here are my previous babysitters. Shirou, Rocket, even Red XIII!" Asriel said, showing photos of manly males, although humiliated just like Legoshi. The first was a silver wolf wearing maid attire, and when he was changing, it was apparent that he was also enjoying himself quite a bit. He was given a sponge bath and had his clean, muscled physique covered in glitter and face paint. Next, was a buff raccoon, exposed in bikini bottom, with his abs covered in honey and other sauces, obviously forced to have his chest glued and hardened by the sweet liquid. Lastly, a feral lion-like creature, dressed in a bunny girl costume and holding a carrot up to his mouth. All of them looked completely humiliated, and Legoshi couldn't help himself but feel disgusted and pity. But above all, he dreaded this would become his future. Once and for all, the wolf was officially doomed. Then he looked at the time, seeing the torture was now finally over since Toriel should be nearby. He lowered his diaper but Asriel smacked his hand away.
"What do you think you're doing? Bad boy!"
The goat lowered the diaper himself, ready to spank him, but he rested his foot upon a soft, pink-colored pillow, stepping down and making the tired babysitter howl in pain. But the smacking could be heard by a few neighbors. Still, it was embarrassing and the wolf moaned all while doing nothing. The once proud wolf screamed and flailed like a real baby, crying loudly and forcing both him and his abuser to cover their ears. Then, he was no doubt going to be expelled from the community for hurting a child. Asriel kept abusing those gigantic butt cheeks and tensing up each time Legoshi reached the loudest possible volume.
"Now, stand in the corner for being such a bad boy!"
Legoshi grunted and obeyed, standing with his massive rear in plain view. Feeling warm, he had no idea what else was bound to happen, and with a bright red mark decorating his ass, he wanted a break, and so badly. With diaper around his ankles, he waited, as footsteps and the door slowly opened. It was Legoshi's doom, ready to scold him and take him off the payroll. Legoshi couldn't react, but somehow, his world suddenly filled up with a calm, motherly aura.
"Dear god, what have you done to him?"
Legoshi's tail instinctively pointed at the sky, in an exaggerated, fanatic expression, one second away from pissing his underwear in fear. Her voice seemed neither mad nor upset. Seeing a woman this close, Legoshi gulped and took one long look at her breasts and wonderful curves. She was stunning.
"He was a bad boy, so I had to teach him a lesson."
"Asriel! How many times have I told you not to treat babysitters like this? You're grounded, mister! Now, clean the living room and think about it."
Without any remorse, the woman closed the bedroom door, and as calmly as she entered, embraced the dejected Legoshi. Pulling him closer to the soft, bulky muscles on her body.
"Come here, little one... my brave, good boy."
Mommy kissed him several times, trying to wipe the tears from his red face. She looked down, seeing his massive boner, giggling at its length and bulging veins.
"Oh, someone is very excited to see Mommy! But let's get you changed!"
She removed the stained garment and grabbed a wet piece of tissue. Tenderly cleaning his prick and balls, gently and cautiously scrubbing the skin on his member. After wiping his backside, he received a generous amount of baby oil, soon followed by a quick powder job. She took the clean wolf to dress him back into his clothes but was forced to replace his destroyed panties with a fresh set of diapers.
"No... I can't go home with this!"
"Shhh, don't worry. Come, there's something I need to show you."
Toriel suddenly lifted her robe, revealing her fat, untouched, and surprisingly juicy buttocks, with her feminine diaper on full display, however instead of just lifting the garment, a part of her pristine suit fell apart as the seams were instantly severed. From now on, Legoshi has only one choice, either agree with her or suffer the consequences.
"But why? Don't tell me your kid--"
"Shhh. Between you and me, I sometimes allow him to discipline me and punish me, cuz it feels better than any punishment ever given by anyone. Even the spanking doesn't hurt as much as during the first time. But I'm thankful for your help, I hope you can come back sometime soon..."
Legoshi thought about that and all the torture he had gone through, but being pampered and taking his revenge afterward did sound good.
"Alright, I'll do it..."
