Dmitri wasn't really that happy with having to suddenly babysit. The coyote had enough work as it was; now he had to look after some kid too? He clicked his tongue as he went to answer the door, grumbling the entire way. Before he could even say his piece as he opened the door, he suddenly had a bunch of crap - snacks, blanket, stuffed animal, clothes, and instructions were said so rapidly he didn't have any time to process them before the door was once again slammed. He stood there, head tilted in pure confusion for several seconds, before he felt a tug on his shirt and looked down. A small cat boy with tiny wings and a faintly glowing halo looked up at him. 
"Uh. Hi," Dmitri said. "Angel?"
"Are you mister Dimty?"
"Dmitri. It's Russian."
"Dimtree."
"Close enough. You want some lunch?"
"Yes!!" The little kitten purred happily.

At first, Dmitri mainly just felt annoyed still. Sure, it was super short notice, but didn't this kid have [i]anyone[/i] else? Not just a bachelor coyote guy in a shitty apartment? He sighed as he stirred the mac and cheese on the stovetop. Angel stood against the counter watching him quietly, his tongue sticking out slightly. 
"Want some bacon bits in this?" Dmitri asked.
"Nuh...meat makes me sick."
"Oh," said Dmitri. He cleared his throat awkwardly. He finished cooking and made Angel a plain bowl, then a bowl full of bacon bits for himself. He hesitated before finally nodding to himself and grabbing a beer, then sitting down with Angel on the couch in the living room to eat. He put on cartoons. Thankfully, Angel seemed easily amused by them. 
"How old are you again, kid- I mean uh, Angel?" Dmitri asked, sipping his beer.
"I'm eight!" he said with a cute grin. "But they treat me like I'm a baby..."
"Yeah, I noticed the pacifier." Dmitri shrugged. He wondered why they'd do that, but he decided not to ask. Angel seemed pretty focused on cartoons, so he didn't want to ruin what he assumed would be a rare moment of silence. He finished his food and grabbed another beer. The odd pair zoned out to cartoons for a while. He grabbed another beer. He was starting to doze off when he felt Angel gently prodding his arm.
"Mister? Can you um, help me with something?"
"Huh?" Dmitri stretched and yawned and looked down at Angel. "W-wait. Where are your clothes? Why are you wearing a diaper?"
"I tried to change it myself," Angel said, as if that explained everything. Dmitri stared at him for a minute. His chest was flat, though had nipples running down both sides, barely peeking out of his fur. His skin was a soft, pretty pink color.
"Mister?"
"S-sorry," Dmitri stammered, slowly standing up. He was definitely a little drunk. And a little horny. But he tried to ignore that last part.

Dmitri laid a towel down on his bed and Angel climbed up and laid back on it like he was used to that sort of thing. Dmitri shook his head a little. [i]He just wears diapers, so obviously he's used to being changed...why does he look so cute like that though?[/i] Dmitri sighed and rummaged through Angel's stack of things before pulling out a clean diaper. He stood over Angel and his gaze drifted again. Thankfully his diaper didn't stink - it was just a bit soggy and discolored from pee. Without thinking, he absently reached down and held the front of it in his paw. Angel giggled, his little wings flapping slightly. Dmitri's dick twitched in his sheath, and he felt a blush spread across his face. 
"So I just. Take it off?" Dmitri took a deep breath to strady himself before reaching up to the tape. He carefully removed the taped tabs. Angel was perfectly still as he pulled the front of the diaper forward, over his thighs - and his breath caught in his throat. [i]Shit. He has...a pussy?[/i] Dmitri's face was unbelievably warm.

"L-lift your hips up," Dmitri muttered. Angel obidiently lifted his hips so Dmitri was able to slide the diaper completely away. Angel's thigh fur was slightly damp and sticky with pee. His tiny pussy, which was barely even visible under his fur, glistened slightly as he moved. Dmitri felt lightheaded. His cock was throbbing by that point; knot threatening to get stuck in his sheath. 
"What do I uh, clean with?" Dmitri asked.
"Baby wipes, I think?" Angel tilted his head and smiled. [i]Right,[/i] Dmitri thought. [i]Baby wipes...fuck, man.[/i] He finally found them in the pile and returned to Angel, posed over him carefully. He took a wipe and started with the boy's thighs. Angel shuddered slightly.
"You okay?" Dmitri asked.
"It tickles." Angel stifled a giggle as he worked carefully on cleaning. He felt pre staining the front of his jeans, but refused to stop just yet. After cleaning Angel's thighs, he realized what part he'd be cleaning next and felt a lump appear in his throat. Angel peacefully laid back, legs spread, tiny pussy teasing Dmitri in a way he'd never felt before.
"Hey, Angel," Dmitri said, licking his lips slowly. "I'm just gonna...feel what needs cleaned, okay?"
"Mhm!" Angel said happily. Dmitri slowly reached out. He traced the edge of the kitten's pussy with his finger. Angel seemed really happy and relaxed, even purring as he traced his slit. He carefully used two fingers to spread it open. He was [i]drooling[/i] at that point - both from his mouth and cock as he took in the gorgeous sight. 

The pent up bachelor began rubbing Angel's spread slit. Angel purred happily as he groped, rubbed, and touched with absent horny intent. Angel was getting wet as he rubbed and explored with his fingers. It wasn't piss. Warm kitty cum coated his fingers and dripped onto his palm. He pulled his hand away and brought it to his muzzle, tasting it. It was slightly sweet. He didn't ask for permission for the next part. He knelt down beside the bed and grasped Angel's thighs, pulling him to the edge of the bed. Angel didn't mind, still purring as Dmitri pressed his muzzle against the wet spot. He started cleaning Angel with his tongue. Angel shuddered, deeply. His purrs hitched and he was breathing harder. Dmitri reached down and finally gave some attention to his aching cock, unzipping and unbuttoning so he could fondle himself while eating out the perfect little pussy.
"M-mister," Angel finally gasped, making Dmitri pause. He wasn't planning on stopping, but...
"A little lower?" The little kitten asked. Dmitri smiled and nodded. Angel's soft little mewls, moans, and cries soon filled the room as Dmitri eagerly lapped up his sweet fluids. He couldn't help but let his tongue slip inside, and Angel rewarded this with adorable little shivers and louder moans. With one hand wrapped around his sheath and the other around Angel's thigh, he couldn't help but feel as if maybe he should babysit this little dude more often. 

Dmitri stood. Angel was panting, shivering, and squirming against the bed. There was already a damp spot on the towel from a mix of Dmitri's drool and Angel's cum. Dmitri stood with his sheath and balls in full view. Angel didn't seem to care, instead quietly touching himself while Dmitri debated how far he was willing to go. While touching himself, Angel made a soft "ah!" noise and suddenly peed himself, creating a little puddle on the bed. His tongue was sticking out as he twitched and shuddered. It looked like he came, but couldn't completely handle it and pissed himself in the process. Which meant he was nice and wet now. [i]Which means...Ah, fuck it. I just won't knot him.[/i]

The coyote held Angel's thighs open and leaned forward. He slowly brought the tip of his lipsticking cock to the kitten's hole. He smeared pre against the boy's inner thigh as he positioned himself. Angel didn't struggle, just looked up at him expectantly and purring a bit. Dmitri slowly exhaled as he slid the tip inside. Honestly, he ws kind of surprised how easily he slid in, considering just how small Angel's pussy was. 
"Wh-whoa..." Angel gripped the sheets and grimaced slightly as Dmitri slipped inside. "That feels kinda, um, weird."
"Just relax," Dmitri muttered. He grunted as the length of his shaft sank slowly into the kitten, visibly spreading his tight little hole to its limit. Still, Angel didn't fight him, just startedbreathing really hard. Air hissed through Angel's teeth as Dmitri began to slowly move his hips, slipping his cock in and out. Even just his thin shaft was enough to pull and tug on Angel's pussy every time he slid his cock out. [i]Guess I'd better keep it nice and deep inside then,[/i] Dmitri thought absently to himself. His legs shook as he pushed in to Angel's absolute limit - enough to make the little kitty cry out, and Dmitri quickly covered his mouth to make sure none of the neighbors could hear. Dmitri started fucking him for real. His cock buried as deep as it would possibly go, he gave the kitten short, hard thrusts, drool dripping from his muzzle as he watched himself stretch the hole out as far as he could without tearing it. He definitely wouldn't be able to knot it - hell, he was already against the kitten's cervix without the full length of just his shaft inserted - but [i]fuck[/i] he couldn't help but drool thinking about it. Angel let out little muffled whimpers with every hard thrust, and Dmitri was starting to pant.
"Fuck," Dmitri moaned out. "You feel fucking amazing. Feels like I must bust through your cervix, huh?" Dmitri grinned, gazing down at Angel's tearful face. He suddenly remembered something that Angel's guardian said during that deluge of information. [i]"He's a bit of a crybaby. But just reassure him if you have to be rough and spank him or whatever - tell him he's a good boy."[/i]
"Good boy," Dmitri moaned to him, feeling his balls start to tighten up. Angel made very cute mewling noises against his hand, still firmly clamped over the kitten's mouth. Angel then, unexpectedly, began to shakily move his hips against Dmitri's rough thrusting. 
"Yeah?" Dmitri asked, gazing into the kitten's watery eyes. "Does it feel good, kitty?" To his surprise, Angel nodded against his hand, even with tears streaming down his face. [i]Fuck[/i]. 

The coyote let go of Angel's muzzle, and the kitten gasped and moaned sharply as Dmitri gave him another quick thrust, slamming into the kitty's cervix. 
"Good boooyyyy," Dmitri growled softly. "Want me to cum inside? Give you a nice big belly full of cum?"
"Yessir," Angel gasped, their body trembling. "Please..." Dmitri wasn't about to go back on his word. With a grunt, he pulled the kitten to him sharply while shoving his cock in as hard as he possibly could. Angel [i]sobbed[/i], but froze against him, fluid trickling down the length of Dmitri's cock and over his knot and balls. 
"I'm," Angel whimpered out. "Ohmygosh. I'm right - there!" Dmitri's hips froze too. The very tip of his canine cock was being squeezed [i]hard[/i]. Had he managed to penetrate this kitty's cervix? That was a thought that went away with fireworks suddenly exploding in his head as he came hard. Panting, the coyote flooded the kitten's womb with potent canine seed. He growled and grunted as his balls strained, desperate to give every little drop to the boy. Angel made a soft noise, halfway between a sob and a moan, then went limp. The kitty had passed out. Dmitri stayed inside, pumping cum inside him and watching with intense satisfaction as the kitten's tummy visibly bulged out from the amount of cum he was pumping inside. Dmitri licked his lips slowly as his cock finally stopped flexing inside the kitten's tight little hole. He waited for it to go soft before slowly moving away - even then, Angel's pussy was still tightly tugged around his cock as he pulled out. Angel's well-used hole was gaped open and drooled cum out of it. As Dmitri stepped back to admire his handiwork, he made a decision - that he'd be asking to look after the little tyke even longer than a night, next time.

Dmitri leaned over the unconscious kitten and kissed his forehead. 
"One of these days," he muttered, "You'll learn to take the whole thing, knot and all." Angel purred softly in his sleep.
