On a lonesome street, sometime years ago, Fyrre was just an infant black dragon learning to crawl for the first time.  In his homely little house, he struggled to flap his wings and galumphed about with clumsy feet across the floor, whilst his four-legged parents sat on the couch together.  Both were ebony and coal, the mother in a silken red gown whilst the father was in a smouldering dark suit.
	"You did call him, right?" asked the husband.
	"I diiiid, yes," the wife sighed, "it's not even 6:30, he'll be here, he came very highly recommended."
	"I know, I know, I just worry, this'll be the first time we've been out since we've had him."
	"I made certain, a lot of my friends recommended him as a wonderful sitter."
They looked towards the clock that ticked ever closer.  Five minutes from now, Fyrre would receive the best babysitter in his life who would open his mind to so many ideas of new play and life-enrichening experiences.  But not this time, thanks to a friend from the future when in their backyard, something cracked in the bushes and pulled at the leaves.
A sparking tear through existence ripped shockwaves across the air, and shook the wooden fence like a ghastly foul wind.  Stepping forth through the black rift of stars, an ice-blue dragon entered the world on two legs, wearing a white cotton shirt and jeans.  Sapphire streaked down his tail and inside his wings, whilst the darkest mane of midnight azure wrapped round his neck.
	"Haaaah, fuck yes," he pulled up his watch, "alright, should be the right place, he said this was when his favourite babysitter first came."
His device beeped with a year, month, day and time, as he skulked through the bushes and waited for the babysitter to arrive.  Despite the long roads, not many cars were present in this world for most dragons flew everywhere, but heavy goods vehicles still existed to carry supplies to and fro.  At that cozy little bungalow, in a quiet cul-de-sac, the sound of wings came through the air and another two-legged white dragon soon landed at their door.
He was rather giddy about his first time with Fyrre, having a small clipboard of likes and wants in his green jacket and pants as he readied to knock the door.  Then came a shot to his neck, and he collapsed almost instantly when a spark ran through his head, and the blue stranger quickly grabbed him to put in the bushes out of view.
	"Sorry, buddy," he chuckled, "this is my night to shine, you won't be in any trouble."
Once the babysitter was safely hidden, the arrival grabbed the checklist he had to get a full read on his name and details, then used his watch device to alter the writing to be his name instead.  He stepped up to the door and knocked sharply, to which the parents shot up immediately and opened up to greet him.
	"Oh, hello!" the mother clutched her hands.  "Thank you so much for coming, and right on time too!"
	"I always am," the stranger bowed, "thanks for having me, it's rare I get to meet someone so beautiful out here."
	"Oh, well!" she blushed with a happy purr.  "Thank you very much um, Darius, was it?"
	"That's what it says on my sheet!"
	"Now I hear you came highly recommended," the father welcomed him in, "what qualifications do you have?"
	"Right here," he offered the checklist, "I've never left a fussy hatchling unsatisfied, I can tell you that, sir."
	"Hmmm...well, that is impressive," the elder read through it and handed it back, "we appreciate you coming, Darius.  I didn't expect a teenager to be well-prepared."
	"Well  you either do a job right, or don't do it at all."
	"Very true!  I'll have to be away for the rest of the night, but my wife will return around 11."
	"No problem," the not-Gavin swept his hand and took the wife's for a gentle kiss, "I'll make sure the house is cleaned out so this gorgeous  gal won't have to lift a finger."
	"Ohohoh, and such a charmer, too!" she blushed.  "Thank you, Darius, now you have all the details about our sweetie Fyrre?"
	"Ohhhh I sure do," he walked past to look at the little hatchling, "him and I are gonna get along just fine, aren't we cutie?"
	"Buuuuu!" the tiny one waved his fat paw.
Currently, Fyrre was trying to build blocks into a castle in the middle of the living room floor, his pudgy fingers trying to grip the wooden sides and balance them on top of each other.  He was a black ball of baby fat, with silver-white horns and claws and a cute little bell collar that jangled round his neck.  Darius helped with the other side, and stacked a tower before meeting in the middle with the central garrison.
	"Heyyyy, look at you, big scary dragon," the babysitter teased, "gonna take this castle for yourself?"
	"Bwaaaaarrr!" Fyrre raised his tiny paws.
	"Hehehe, ohhh you're all fierce huh, gonna scare the li'l villagers?"
The boy pounced on a few models lying around, shaking them in his mouth like a cat with a mouse as the parents laughed at his eagerness.  They waved goodbye to Darius and Fyrre, and once the door was closed, the new babysitter cracked his knuckles.
	"Alright li'l guy, I'm here to fix the timeline proper."  He leaned over the castle and showed off his watch.  "Name's Darius, I'm from the future to make sure you never exist.  Now what do you to say to that?"
	"Mmrrrrr?" the infant sucked on a toy soldier.
	"Yeah, that's the same face he gave me.  Look."
From his watch he showed a small video file of an older Fyrre trotting about in the future, doing some assistant work in a lab as he carried beakers to and fro.
	"Now, your parents are paying me to tire you out, good thing their money's still good in the future so I'll do my job right.  So why don't we get you all tired out, before I abort you with my fat dick?"
	"Behhhh BAH!"
The toddler-drake flapped his purple tongue and kept building his castle, when he wasn't trying to gnaw on toy soldiers.  The fortress was soon built with a courtyard and four towers, to which Fyrre started running around and barking at with some deep ancestral urge, whilst Darius leaned back to bap the boy with his feet.  The hatchling grew more interested in them and started to jump towards them, glomping with gummy teeth before he was kicked away to race back around the castle, stalk the other foot and lunge for it instead.
It was a lovely time of normalcy that Darius let him have, getting himself ready and horned up when he dove his hand into his pants, and started stroking himself up to a nice plump erection.  He was aching for this ever since the idea first came, to travel back to Fyrre's infancy and put him where he belonged, his watch keeping a check on the young drake's existence by detecting his DNA, before the hatchling started to pant and stumble.  He was finally tiring out, which was the teenager's cue to pick up the boy and put him to bed.
Fyrre hugged him tight, nuzzling Darius' neck with a happy sound as he was carried off to his nursery.  Fyrre's room was a perfect home for a baby dragon, having a dome-shaped bed resemble a small cave with various cuddly toys stuffed in each corner.  The walls were painted like a medieval fantasy, where castles loomed and dragons danced through the clear blue skies over rolling meadows with cute little cows.
Darius sat on the floor and slipped off his pants to reveal his throbbing meat, a swollen pink shaft that rose from his slit when he offered it to the black pup.  The babe groped for it with a curious sound, and the teenager grinned at such forwardness when he sat back against the wall surrounded by plushies.
	"Thaaaat's a good boy," said the babysitter, "you gonna snuff yourself on my dick, hmmm?  Like you deserve."
The boy sucked on the head with a happy sound at the new taste, that sweet-salty texture from the pulsing glans that already fed a wad of pre into Fyrre's throat.  The hatchling squeaked in excitement at the milky goo and sucked faster when it dribbled thicker into his gullet, a greedy little thing who flapped his tiny wings in mumbling joy.  Darius petted his head and watched his own cock grow thicker, then gripped the tiny horns to keep him still and allow his shaft to push into Fyrre's throat.
At first the infant struggled with choking sounds, a few coughing sputters that only made the teen throb harder.  He then shoved his girth deeper in as it rose to a hefty 6 inches, widening the drake's throat as his whimpers turned to fidgeting screams, and his eyes watered with a great effort.  He started to suffocate, a harsh gagging noise mixed with squeaks of peril, then his throat widened with a dry heave and nostrils flared.
	"Shhhhh, just let it happen," Darius soothed, "no one's gonna miss you anyway, so just accept it.  Be a good boy and die for me."
The teen rolled his hips to clap against the hatchling's cheeks, testing his lungs as the vibrations of his screams rang down his spear and made Darius shake with excitement.  Such a tight and perfect sleeve for his cock, so wet and hungry for milk as he stuffed down the whole gullet and reached Fyrre's belly, feeding him his pre directly much to the infant's frantic cries.  Longer he grew, thickening to a single foot long that bulged out the newborn's stomach with a gurgling croak.
Darius watched the little brat choke on his pulsing lance, and waited for him to almost pass out on that fleshy pole before pulling back out.  The small tongue slobbered around his meat and flicked over the throbbing veins when it slipped back from his gaping throat, and left a trail of slimy drool down each other.  The boy whimpered with sniffling tears and pushed it away from him, but the babysitter had other ideas as he flipped the hatchling round, and rubbed his lubed-up cock against that tight little pucker.
	"Mmmmmmhhh, feel that?" Darius teased.  "That's the end of your life right there.  Don't worry, I know everything about your mom, so I'll make sure she's happy with a better kid."
With the hatchling forced on his front, the teenager pushed his cock into the fresh virgin rear, splitting the tiny bud apart as the newborn shrieked with agony.  Fyrre sobbed with a wretched noise, an ear-splitting timbre that made Darius throb even harder, and his watch started beeping with TIMELINE ALTERED flashing across its front.  The harder he thrust, the more rapidly it beeped as he gaped the newborn slut with such violent force, that the creaking of his little hips scraped on Darius' ears.
Then came the brittle crack, and with it the growing of the teenager's fat schlong to reach even further beyond.  He grabbed the hatchling's tail and shoved harder, snapping his sad little hipbones to render his back legs permanently crippled, a sharp splintering agony ran through the infant's lower body to make him screech even harder.  His cheeks burned red with suffering, his eyes burned with bloodshot anguish, and Darius drilled deeper into his guts to either tear them easily, or force them straight to be his cocksleeve.
	"F-fuck," he whispered, "fuuuuck yes, gonna f-fucking cum in you, Fyrre.  Gonna cum in your little baby ass and wipe you off my dick like the rest of your timeline, m-MMMMPH!"
The babbling shrieks continued on as Darius pumped his way in, stretching that boy's belly to form into his personal cockshape.  Bulbous tips all down the sides of his halberd tickled the infant's insides, stretched him ever wider as the bands of his stomach bulged even further.  Soon he was impaled enough for the teen drake to pick him up with both hands, and slide him down on his cock like a leathery fleshlight.  He walked around the house with Fyrre stuck to his shaft, jerking himself off with the dying hatchling's corpse as his screams started to fade, his frantic paws kicked a little less, and the watch beeped more violent about CRITICAL SEVERANCE APPROACHING.  Then the phone rang from near the TV, and Darius walked over to sit down.
	"Yyyyello?" he picked up the phone whilst pumping the child.  "Ohhhh hey there, miss!"
	"Hello, sorry to bother you!" said Fyrre's mother.  "How is everything?"
	"Ohhh we're doing fine, I just put him to sleep.  Li'l guy took a lot in him, but he's off and away now."
	"Wonderful!  He usually takes another hour before he's all tuckered out, what's your secret?!"
	"A lot of milk," he groaned as his cock pushed out of Fyrre's throat, "and a good run-through.  He'll be asleep for all night, guaranteed."
	"Well, that's excellent news!" the mom tittered on the phone.  "I should be back at 11 to pay you."
	"Appreciate it," he flexed his girth to make the child's jaw creak, "aaaaah I'm real tired out, haha, I'll just hang here in the living room until you're back."
	"Thank you, again, I'll see you soon!"
When he finished the call, he kept pumping the fucktoy with a happy groan, his throbbing prick rising out of Fyrre's maw as he watched the baby's eyes turn hazy.  His eyes rolled up in a silent anguish, his final breath rattled out of his throat now fully blocked with a fat girthy pillar that drooled thicker pre all over his chin.  At 2 feet long to his maximum length, Darius fucked Fyrre to his timely death, even after his watch beeped with SUBJECT: FYRRE (ERASED).
That alone made him want to cum,  but he held himself back with a shuddering grunt and kept pumping the dead newborn.  Precum slathered down the front of the blackish-grey body, the wings twitched their last spasms and his paws hung down limp with a cock-moulded belly.  Darius took his time, knowing he had plenty of it left with ideas on Fyrre's mom, that sultry slender body wrapped in red with a sensual tail.
Thoughts of her alone helped him on to his orgasm, and soon he blasted a hot wad of jizz all over himself and the hatchling's body.  Their scales were painted white, a fountain splattered down on his lifeless face when Darius pulled back to let the rest of his climax pump deep inside Fyrre's organs.  What was left of his insides were gushed up full of thick cream, a cannon-spurt of jizz sprayed across the floor and almost hit the TV when the babysitter clenched his teeth, and sighed with a longful release.
	"Fuuuuck yes.  Haaaah.  Finally, good riddance to you, cutie."
He slumped back on the chair and let himself recuperate, his massive harpoon still half-buried in the hatchling's rump that bulged with hot milk and dripped out down his killer's cock.  The babysitter picked up the remote and watched TV, with a dead little runt impaled on his shaft that slowly went back down over the next two hours.  He walked around the house to grab food, enjoy some snacks, and lay on the couch with a dead Fyrre bobbing around on his meat.
Once it was 10:30, and he was fully flaccid enough to slide the infant off his meat, Darius tapped his watch and shot out a beam towards the little corpse.  Trapped in a brief stasis field, the body decomposed within a violently-rapid process, the flesh sizzled away and hyper-aged to a fine mulch.  Flesh peeled off and muscles burst into meaty fibre, then deflated like dark balloons until the skeleton revealed itself.  Then the bones turned from white to bronze, and eroded through hundreds of years in the space of mere seconds, until it was a pile of dust.
	"Hhhhahahaha, damn this thing rules," Darius flashed his watch, "can go back, can go forwards, can age specific things.  I gotta thank that raptor for giving me this."
After he put back on his pants, he grabbed a dust pan from the kitchen to scrape up Fyrre's remains and dump him in the trash, but pocketed the bell collar that was still left behind as a personal trophy.  Whilst he scrubbed the carpet clean of both cum and bonemeal, he heard the door open and Fyrre's mother walk in.
	"Helloooo," she whispered, creeping in, "everything alright?"
	"Oh yeah, just cleaning up," Darius kept scrubbing, "li'l guy had an accident while I was changing him."
	"Awwww, that's so sweet of you!" she trotted in on all fours.  "My husband had to leave for an overnight flight so he's sleeping on the wing, is Fyrre asleep?"
	"Ohhhh he sure is," the teen bundled used cloths into the bin, "not a peep out of him.  Guess it's just you and me for the rest of the night."
	"Oh well, I mean you can head on home if you like," the mother reached into her dress and handed over some bills, "here you are, thank you again."
	"Nooo problem," he slipped it in his pocket, "you sure you'll be alright on your own?"
	"Oh yes, it's not the first time my husband's been off like this."
	"Seems pretty lonely though, lady like you shouldn't be alone by yourself."
	"Really?" she cocked her head.  "And what do you mean by that, young sir?"
	"Just that someone as gorgeous you, I'd never leave their side no matter what."
Her smile grew into a rippling chuckle, and she patted his head patronisingly before walking back to the door and opening it for him.  But instead, Darius closed it and crossed his arms, giving a wider grin as her eyes grew with concern, but all the teenager did was pucker his lips and make her blush at his wants.
	"Young Darius," she began, "you do realise I am married, and much older than you."
	"Not a problem to me," he leaned in close, "you know why I came so recommended from all your neighbours?  It wasn't just cuz I'm good with kids."
	"Are you...no, surely not."
	"They won't tell you, obviously, but you notice a lot of them have husbands who go away often, don't give them all their needs, leave them all alone...it's just kind of fact by this point, why else did they recommend me to you?"
	"N-n-no, nooooo you're fibbing now," she bapped his snout, "you're young and eager, and one day you'll find a fine lady, not this second-hand maiden."
	"Second?" he scoffed.  "You're first class all the way, never put yourself down, you're beautiful the older you get."
	"W-well!  Uhm...th-thank you, Darius.  But I think it's time that you-"
	"Get down to business?"  The pale-blue drake thumbed his pants.  Satisfaction guaranteed from all your neighbours, who aren't gonna say anything, but all know whether you were too prudish to join the club."
His smile remained as his slit bulged out and pressed against the seat of his pants, enticing Fyrre's mother who licked her lips with anticipation.  Such young and bold confidence reminded her of her husband when they were first dating, but his new life and job had taken a toll on him, and left the wife with so much wanting.  Ever since Fyrre's birth, she had been helplessly pent-up and knowing she would have all the time in the world, she slowly locked the door and pushed Darius back.
	"You better live up to expectations," she purred, "or I'll be leaving quite a bad review."
	"Oh I will," he unzipped his pants, "where you wanna do this?"
	"I'm not waiting," the mother grabbed his arm and walked three-legged to the sofa, "show me your resumé, boy, let's see if your tongue's as good as your words."
She mounted the chair and hiked up her rear, showing off her two holes one of which was dripping already.  She struggled not to whimper as her back legs trembled with desire, and Darius stepped up close to grab her haunches.  She was gorgeous in all the right parts, his fingers crept along the scales and his thumbs pressed on either side of her sweet lips.  The babysitter bent down to slurp across her holes, tickling her to make her whine as her tail stiffened up above his head.
	"Ohhhh you're beautiful," Darius smooched over the cuntlips, "how is your husband not stuffing you every night?"
	"H-he gets so busy," she gasped, "don't, don't tease me, th-this is already bad enough."
	"But you love being bad, don't you?  Every lady deserves to be a little bad."
Her breath was soon caught in her throat when she felt the tongue press into her snatch, flicking over the walls and swirling around the rim to savour that sweet mature taste.  The mother whimpered at his roaming tongue, how it drove deep inside and how his thumbs teased her in such a way that her husband never could manage.  Darius had learned very quickly how to please a lady, and found all her sensitive spots within minutes of slithering his tongue through her depths.
He pumped on her walls and flicked against folds to make them shiver in a rolling motion, as he soon sucked down her sweet juices that filled out over his tongue.  It wormed around the depths and undulated like a serpent, trying to hit every little inch of her tunnel whilst her tail twitched in constant spasms, and she drooled even harder from her snatch to the point Darius was struggling to lap it all up.  It was time to mount her, in one last insult to erasing Fyrre's existence when he stood up and rubbed his dick on her cunt.
	"Wh-what, what are you-"
	"Shhhhh baby," Darius gripped her tight, "your body's so wet, you need this badly."
	"I...I-i-i...ohhh, g-gods."
She made no move to resist as she pushed back against him, silently begging for him to use her as the teenager slipped inside.  Already hard at 6 inches, he grinded against her walls and drilled deeper within, his hands slipped up to her tail for extra grip to start pumping away much to the mother's glee.  The four-legged dragon gripped the sofa cushions and moaned louder, then remembered herself for the sake of her "sleeping child" elsewhere.
Darius went along with it and kept his breaths subtle, baring his teeth as his meat grew to a thicker size and grinded harder into both walls of her trembling snatch.  The traveller from the future bucked his hips harder, pressing her against the couch until she started biting one of the cushions to restrain her whimpering from how deep he was starting to get.  Longer he grew with contemptuous passion, fucking the mother of the infant he slaughtered as he throbbed even harder and started to kiss at her womb entrance.
	"Haaaah!  A-aaah, w-wait, don't, don't cum in me."
He pretended not to hear, pumping away faster as his length thickened to a foot long, then even further once more to fill out her whole canal and make it into his personal cocksleeve.  Darius panted with a thickening drip of pre that trickled out of her snatch, mixing with the mother's juices that drooled into a puddle on the floor.  Having already used a previous slut, he wouldn't take long to reach his second orgasm of the night despite trying to hold himself back, whilst Fyrre's mother clenched harder on his spear.
She mumbled half-protests but her mind was enraptured by how deep he went, the stabbing blunt thrusts of her son's killer making her warble with pleasure, her claws dug into the couch and she thrust herself back for the full impalement.  She almost regretted it from the sharp strike of Darius' bulbous tip forcing her cervix apart, and getting sucked off in turn by her entire body vibrating in rapture.  Too late did she cum, and in turn so did Darius, the teenager gripped her tail and flooded a hot rush of pure dragon seed straight to the source.
	"A-AAAAH!  N-n-n-no, no, I-i said don't-O-OHHHH!"
But she could not stop herself, her eyes rolled in rapture as the young biped pumped her depths to the brim, and washed out a steady stream of white between their legs.  The traveller-babysitter sighed in relief, and slumped against her backside briefly to regain his composure, whilst grinding his cock in her tunnel.
	"Mmmmmmhhhh yeah.  Haaaah, sorry about that."
	"Y-y-you just," she looked back in fright, "you...I told you not to."
	"You didn't exactly scream it out loud," he shrugged with a devilish grin, "I'm sure you can find a way to fix that."
	"No, no no no, you, you just...you," the mother kicked him back firmly, "I can't, I-i wouldn't be able to explain, my husband if he finds out-"
	"Hey, hey, it'll be fiiiine," he steadied himself and stuffed his massive dick back in his pants, "I've done this before, the other wives won't tell you but, how many of their kids you think are mine?"
	"And you...you just let that happen?"
	"They did, they were the same as you, not exactly begging me to stop, you just have to make sure you get your husband horny before it's too late."
	"I...maybe it won't happen," she muttered, sliding off the couch, "maybe I can just, find a way, and...fix this."
	"I'm sure you can, but if you need any help, I-"
	"N-no, thank you."  The mother pointed to the door.  "You should leave, and...thank you for the...service."
	"Glad to help."
He tipped an imaginary hat and stepped out of Fyrre's home.  Exhausted and wracked with guilt, the dragoness would go straight to bed without checking on her son's room, and not know until too late that he was gone and erased from existence.  Darius pulled out the real babysitter's body from the bushes, just enough for someone to see him before he tapped his watch and signalled his time of departure, opening another crack through reality to disappear through.  No one had heard of Fyrre in his current time, and not even the black collar with its little bell would stir any memory of that worthless drake, when Darius wore it on his arm like a bracelet from that point on.
