“Joker! Here boy!”  Joker's head perked up from where it had been resting on his paws. Master was calling him and that was all it took for his tail to start wagging. He hopped to his feet and moved towards the door of the small apartment he now called home. Joker’s canine mug stretched into a doggy smile as he walked (not ran, good boys don’t run inside) over and sat in front of his master. “There’s my good boy!” the man said as he hooked a leash to Joker's collar. “Come on Joker, I have a special treat for you!” Joker’s tail wagged faster wondering what this special treat was. “Just a little something to show you how much I love my good boy.” Master said as he led Joker out the door through the complex toward the streets.

Joker had not always been a good boy in fact he hadn’t even always been a dog but that had all changed a month ago.

----

Joker had been looking for Morgana on his own and decided to try the metaverse since the cat could enter and leave at will he figured it was good place to check out figuring that his personas would be enough to protect him starting at the lower levels was probably his second mistake his first being forgetting that he normally traveled the metaverse courtesy of the morgana mobile.
He recalled being stuck on the bottom floor for a long time in fact the reaper showed up just as he managed to leave.  It was a slog and a half and he had been shocked to find an actual palace. Not the half formed ones that were usually littered around the metaverse but an actual fully formed palace. One minute he had been in the twisted subway system the next minute he found himself in a very different area.

The new palace took the form of a castle surrounded by a dark forest of twisted but still living trees. Perhaps it was the rush of having handled so many of the lower floors hazards alone or maybe it was simply over confidence but Joker decided to look through the palace by himself. The castle grounds were populated exclusively by Shadow hounds patrolling in packs of three or four. Avoiding them to reach the main gate Joker had found that it was open and curiously that outside was a sign advertising pet adoption services. Inside the halls towering portraits of famous dogs, wolves, foxes, and coyotes lined the walls. The end of the stairway railings were snarling wolf heads and every door was decorated with fangs. Joker  had fairly little trouble moving through the castle until he reached the basement. Suddenly the environment was covered  in torn cloth and while there weren’t any Shadows there were noisy cages of wire that when rattled summoned a Shadow to investigate. The bottom level featured a locked door strewn with chains, the sound of howling from within drawing him in. An air vent let him into the room and into the first real fight since he arrived.

It was over in a flash; he had barely gotten a look at the shadow still wreathed in darkness before it had surged forward, eyes flashing as its teeth sank into Joker's arm. And then Joker had not been human anymore the changes felt like an eternity as they were happening but had been over in an instant. The moment those teeth released his arm his left hand curled up nimble fingers becoming clumsy paws as smooth shiny black fur rolled up his arms. His phantom thief outfit seemed to dissolve letting him see the stripe of white fur that started at his chest and grew down to his crotch flanked by more black fur. His neck stretched as the fur swept up his body, his mouth stretching out as his nose turned forward and twisted out, joining to form a muzzle. His ears grew out into triangles that flopped over as his hair was covered over by the fur. As the fur covered his crotch he felt strange he twisted his head and watched his balls grow fuzzier and his cock swallowed up by a sheathe. His tail emerging from his rapidly changing ass made him aware of the splot of white fur on his hips. His legs bent as the fur swept down them forcing Joker to all fours. The only trace of clothing on him was a red collar sporting a name tag declaring him Joker and the white fur on his face patterned like glasses. 

Joker stumbled and fumbled trying to coordinate four legs instead of two. He reached for his mask to cast as restoring spell but the mask was missing. “I know you’re a little scared right now…” the shadow resolved itself into a tall black furred wolf- no it was a Werewolf as it grinned down at Joker still trying to get on all fours and looking for his missing gear. “...soon enough though you are gonna see that this is all for the best. You’re probably wanting to return to being a miserable, lonely, pathetic human but believe me you are so much better off becoming a dog. I’ll teach you how to be a good dog, obedient, loyal and sexy. When I get through with you, you'll be real for the hounds. We will have a howling good time and you’ll make for a fine canine soldier.” the Werewolf leaned back laughing as Joker finally got his feet under him and reoriented enough to find the air duct he had entered through. “Let’s get started by introducing you to the other dogs!”

Naturally Joker had hopped into the vent crawling out the other side and bolted for the exit running as fast as his legs could carry him. Haste his only concern he didn’t think for a second about all the guards appearing or taking note of his presence. He was nearly back out in the metaverse once more when one caught up with him. One minute he was sprinting full speed towards the exit and the next his face was in the dirt and there was something pinning the rest of him to the ground.

Joker had squirmed and tried to stand but his canine body was just too unfamiliar to use properly. Then he felt something against his back and froze. The Shadow was humping him, its hips slapping against his rump.  Joker had been in a lot of stressful situations but this was a first for him he simply did not know how to react especially since he couldn’t call his persona. Then he felt something wet. It poked up against the tight little pucker of his ass and then again but this time more forceful. Joker realized what was poking him and where and with great dread put two and two together. 

Squirming harder he earned a growl from the Shadow as its growing erection thumped against his virgin backdoor. Eventually pushing against turned into pushing into and Joker held still because every move earned a growl and each shift was a new twinge of pain from his stuffed backside. The canid Shadows cock was long and seemed impossibly large as it shoved into Joker. The boy was not used to things going up there and the shadow wasn’t being gentle. Joker whimpered pitifully but that only seemed to arouse the Shadow. 

Joker was shocked when he felt warmth from beneath him and realized his own cock was sliding from his sheathe into the dirt. The Shadow hound above him was tireless and merciless, shoving more and more of that long canid cock into Joker with every thrust until the big knot was bumping against Joker's ass. Joker yelped as that knot was pushed up against his ring begging for entrance. The Shadow hound shifted, grabbing Joker's back legs in his front and pulling his ass up and back onto the hounds crotch. Joker yelped and let out a long whine as the knot slid into his body swelling up and sealing the Shadow hounds member inside. Warmth flooded Joker's ass as the Shadow came, its hot seed filling the boy. Joker hung his head ashamed to be filled like this and saw his cock twitching spraying cum on the ground as he was filled. 

The Shadow sat with Joker on his cock for a while after his orgasm stopped. Joker wished the situation would just end. The Shadow hound dumped the boy on the ground before it turned around pulling its cock free from Joker and vanishing as shadows tended to do. Joker had climbed to his four feet again glad now that he wasn’t on two legs as he walked out of the place and back to the metaverse. Except he couldn’t leave, the exit was just gone and with a start he realized his phone was in his jacket which much like his mask was now totally gone. So Joker got to thinking of other ways he could fix this. Perhaps if he got to a safe room in the palace or maybe even getting its treasure would fix it.

Calming down as he started to plan made him aware of changes. Everything here smelled better than anything he could remember. One scent in particular had him drooling, whatever that was he wanted it and wanted it badly. The palace seemed brighter and more welcoming now. As he roamed about the castle learning its layout again he also noticed the doors that had been closed were now open.

Inside though were things the place ruler no doubt wished hidden and so Joker entered each room to be subjected to a one act play  of sorts.  And so he learned the name of the palace's ruler Lyle Sommer. Bit by bit the story came together. An American who had come to Japan with the promise of riches and a cushy job in acting ,an offer made by a literally two faced man if the play was to be taken at face value. His dreams dashed when he arrived learning his recruiter was nothing more than a host club owner. With no family to call for help, no money to return to America and no job he fell into poverty only able to find work at a dog shelter. An abusive boss and thieving landlord stole any chance of ever living happily. Then came the ascension to power. Lyle found a little happiness with the dogs he saved that threatened both his boss and landlord. By sheer coincidence the mental shut downs killed his boss making him the top dog at the shelter. Lyle then used his new position to accuse the thieving landlord of a number of crimes which had swiftly seen the landlord carted off. For reasons the plays skipped over, Lyle ended up in charge of the apartment complex.  

Following those reveals most of the rooms just contained cognitions of people being horrible to  dogs and then crying when Lyle appeared to take them away. Some of the cognitions were violently angry one moment and then cowering the next. Briefly, Joker heard Lyle speaking in another room. 

“There’s just about nobody I can trust anymore. Humans are so disgusting all so obsessed with themselves never thinking or caring about others” Joker overheard Lyle saying from what sounded like a room below. “That’s why dogs are the greatest. Always loyal and obedient. Always there to cheer you up, so eager to please.”  Joker found the thoughts lingering in his head as he tried to get closer to the voice. Like a bee circling his head he kept coming back to the thought.

“Am I a good dog?” Joker found himself asking one minute only to dismiss the notion. “No, I'm not a dog at all!” By the time he got down to the floor below the voice had moved off but that super amazing smell had returned.

Following his nose he became aware of another change, the guards were ignoring him. Feeling bold he walked straight in front of one of the hounds and while it turned to look at him he got no further response.  A lightbulb went off in his head. Of course he would be above suspicion here. The palace’s ruler was unfailingly kind to dogs; it was only people who he was suspicious of. Joker roved about the place with relative ease now mapping out the entirety of the palace even finding the treasure room.  Without a calling card though he wasn’t going to be able to steal the treasure. Seeing as he couldn’t get to the real world to send the card that avenue was out as well. 

Eventually he came across a safe room but there was a dead end to his goals there too. Sure the safe room was preserved from the Shadows and let Joker fall asleep but he was still stuck as a dog. It was in a safe room mirror he finally got a good look at himself. He was unable to really identify his breed; he was some manner of mutt, perhaps a lab or dalmatian judging from his coloration and general body type. Of note was that the dog tag which bore his name was shaped like the Phantom leaves logo and that his collar flat out read Phantom Thief Joker in the same clipped newsprint they used for calling cards.

Day two of his journey of the palace moved down to the dungeons where there were now cognitive dogs all yelling happily. 

“Master is back with treats!”

“Play time~ play time~ master is here so play time is near~”

“So many friends and a Master that keeps us all clean!”

“Master's is so good to me. I get extra food for being a good boy.” 

The shouts of the elated dogs all singing the praises of their master was a bit much for Joker though it did put some thoughts in his head. Like what was it that gave Lyle a distorted heart strong enough for a Palace. Were the dogs hje took care of really that happy? Would Joker be happy like those other dogs if he was a good boy? Joker shook his head dispelling that last thought. Though much like his questions on being a good boy it came back. Everywhere he went in the basement there were more dogs happily praising lyle. Well the ones whose mouths weren’t otherwise occupied at any rate.

Many of the cognitive dogs were in the process of licking each other's asses, sucking cocks, licking canine vaginas. Males and females both were being mounted some being fucked in the ass like he had been the females almost exclusively having their pussies filled. 

Lyle’s voice rang out over the cacophony of whimpering howling dogs courtesy of a loudspeaker Joker had failed to notice at first due to the obvious distraction. “Good dogs are always horny. Good dogs are eager to play. Good girls love to be bred. Good boys love to breed the girls. Good girls like to be shared. Good boys love to get mounted by their friends. Good boys love to mount their friends. Good boys love to share. Good dogs love to lick and kiss. Good dogs love to suck.”  Lyle said and the cognitions clearly agreed doubling their sexual activities. “Good dogs obey, obeying is what makes a dog good.” Joker foundhimself nodding along unaware his cock had slipped from his sheathe as his eyes watched the dogs fucking and breeding. “Good dogs deserve good owners.Good dogs make good pets. Good pets deserve the best fucking.” Lyles voice continued Joker’s eyes kept drifting to the canid cocks ramming into the eagerly presented fuck holes of the other dogs his cock twitching and drolling beneath him. “Good dogs cum.” Lyle commanded and every dog cognition in the did as instructed and so did Joker howling as he suddenly found himself cummming. 

Running from the basement Joker headed straight for the safe room once more in there he found himself fighting to silence the voices in his head telling him that he was a good dog that he should be proud of cumming on command like that that hew a good boy for being so horny and that he should go back and play with the other dogs. The safe room had a bag of dog foo and with no other option Joker tore into it devouring the surprisingly meaty kibble. Chewing vigorously, loudly crunching on the dog food helped him to quiet the voices. Exhausted from the mental struggle Joker fell fast asleep once more. His dreams however were full of lustful dogs circling him, some wanting to mount him while others were wanting to be mounted by him.

Day three of the search began with Joker coming to the conclusion that he needed to find the Shadow that had done this to him or maybe Lyle himself. His dreams the previous night had him waking up to a throbbing dog boner and It had taken him most of the morning to make it go away. Heading out in the hall he lifted his nose helping to catch a whiff of something he had yet to come in contact with. 

Instead he found something familiar that wondrous scent that he still couldn’t find the source for. He wanted to cover himself in that smell or if it was food he wanted to devour it. Closing his eyes to better focus on the scent he found he snuffled down the hallway. a voice whispering in his ear that he was acting like a common mutt.  As he wandered about he found himself growing frustrated by the way the scent grew stronger and fainter at random as if what he was looking for was moving around. There came a voice in his head telling him that good dogs were patient. Joker squeezed hi eye’s shut as if that would block out the mental voice as he followed the scent. It was inevitable that walking around like that, his nose bumped into something. Opening his eyes revealed that that something was a Shadow hounds tail end. The Shadow gazed at him with a tilted head, the glowing helmet that served as its mask making it look menacing even if it’s posture didn’t.

“Uh sorry i was looking for something.”  Joker said weakly trying to back away. 

“Oh I know what you are after. I’ll take you there…” the Shadow hound said as it circled around behind Joker. “... but first a little something to take the edge off.” 

Joker was surprised not at what was happening but at how his body was responding. His cock slid from his sheathe eager and twitching, his tail flicked up onto his back and out of the way. 

“Looks like you know how to behave.” The Shadow hound said mounting Joker. The phantom thief was shocked to find that the feeling of the Shadows cock sliding into him felt good. He wasn’t dreading this, he wanted it. The hound was no gentler than the one that had first mounted him but this time there was no pain, just the wonderful feeling of the canid cock stuffing his backside. Joker whimpered as he came, his cock not pretending to go soft as the relentless pounding of his ass continued. Joker’s tongue lolled from his head panting as he was fucked  good and hard. His mind reeled as he realized he wanted to feel the Shadow’s knot inside him to be tied and filled with cum.  

“Please… m-more.” Joker said his cock twitching drooling pre-cum like a leaky faucet. He knew he should be ashamed of how good he was feeling at being mated by a dog but it just didn’t matter with how good he was feeling. Beside his own mental voice though there was another voice, Lyle’s voice. Just as loud in his head as it told him there was no need to be ashamed after all, good boys loved to be mounted. 

“Oh, I just know the master is gonna love you.” the Shadow hound said as it forced its knot up against Joker's ass. “Be a good bitch and cum hard for me.” The hound said as his knot slipped into the tight ring and began to swell. Joker howled as he came just like he had been instructed.  A whine of pleasure left him as he felt the warmth from the Shadow hounds cum filling his ass. “Yeah, that's a good boy.” the hound said, dismounting him and putting them ass to ass. 

The Shadow hound dragged him out the door still tied for anyone to see. Joker felt embarrassed as the other Shadow hounds turned to look at him. An embarrassment that mixed with lust as he saw the other Shadow hounds cocks poking from beneath their bellies. Good boys love to get mounted by their friends. Good boys love to mount their friends. Good boys love to share. Good dogs love to lick and kiss. Good dogs love to suck. Lyle’s words came back to him as he was dragged down the hall by the knotted cock in his ass. Joker tried to shake the thoughts away only for  more words to come back to him. Good dogs obey, obeying is what makes a dog good.  Joker was panting as he was pulled down  the stairs, the thoughts getting louder in his head. Good dogs deserve good owners.Good dogs make good pets. Good pets deserve the best fucking. Joker was rapidly deciding that maybe being a dog wasn’t so bad. After all he had never felt so wanted before becoming a dog. Sure he was only having gay sex and as the bottom but it felt good and even being shown off like this was a bit of a turn on. He was dragged into the basement. 

Here Joker failed to see that the same kind of particles that flowed off the Shadow hound was beginning to rise from his own body.  The Shadow hounds knot popped free and Joker dropped to the floor  before quickly rising to follow. As the Shadow hound pulled him through the basement the cognitive dogs began barking and howling. They were wanting in on the fun Joker was having and Joker found he wanted to let them. To mount up the cute girl dogs and lick the big boys. Eventually though he  was led down to the lowest levels of the castle to that locked and chained door he had seen on his first visit though this time the door was wide open. Joker was shocked when the Shadow hound simply vanished leaving him face to face with the Shadow of Lyle Sommer laying on a soft looking bed 

“Oh so you were still here after all. I thought you’d run off for good on me.” Lyle said as he rose from the bed and shut the door behind Joker. A Sight that should have set off alarm bells for the phantom thief but which got no reaction. Joker was far too busy studying the Shadow wondering what  was hiding behind the almost generic features of the man.

“Huh? I don’t think I saw you before?” Joker replied confusedly. Jokers mind was drifting badly as Lyle’s talk about what made a dog good and what kind of things a good dog deserved was rattling between his ears non-stop. Adding to the distraction was  that wondrous scent which was stronger than ever and definitely  coming from this room  Thoughts vanished from his head as Lyle’s hands began to stroke down his back and over his muzzle. Joker’s tail wagged uncontrollably as he was petted like any other dog. Flopping to his side he was delighted when the hands  kept up their attention and began to rub over his belly. 

“Last time you weren't such a good boy and so I looked more like… this!” in a splash of Shadow the human Lyle was replaced with a black furred Werewolf.  “Last time you were just another lousy wretched deceitful human. But I fixed that for you. Why be a nasty lying thieving cheating human when you can be an obedient happy horny dog?” Lyle said clawed hands still stroking ever so delightfully ove Joker's belly, scraping his skin just enough to be delightful. Joker caught sight of the strange Shadowy aura he was giving off but was distracted from it by the werewolf brushing holding his collar. “You used to be one of the phantom thieves right?”

“Yes master!” Joker replied. The passing thought that he shouldn’t be calling Lyle or anyone else master was brushed aside by the much more obvious truth: all good dogs needed a master and he was a good dog.

“Then you know the truth, there's no end to how rotten humans are.” Joker found himself thinking of his friends and how great they were but that didn’t matter right now. “You know dogs are so much better than humans and with a little training from me you can be my good boy.”

“I-I don’t know.” Joker hesitated. He felt like if he gave in here that would be it he’d never be human again, never hangout with the other phantom thieves, never steal another treasure for a second the voice in his mind called out to him to throw off these shackles and rebel.

“I have a treat for a Good boy.” The werewolf whispered before clutching his sheathe, rubbing the fur getting himself riled up. That glorious smell Joker had been seeking intensified as Lyle’s throbbing red canid cock poked free into the air. Just like that all of Jokers resolve vanished.

Joker  shifted onto his back legs not even thinking. His forelegs braced against Werewolf Lyle’s thighs as began to lick at the rod. Joker’s thoughts were drowned out by the smell and taste of the werewolf’s cock. His own cock slipped from his sheathe twitching with delight as he lapped up and down the cock in front of him. Joker angled his muzzle and took the whole length of the Werewolf into his maw, careful not to bite as he slurped on the rod, his tongue curling about it as it furled and unfurled. The Werewolf growled with delight, one of his clawed hands holding Joker's body up as the other scratched between his ears. 

“That’s a good boy. You know what you want now don’t you?” the Werewolf asked. Joker gave no reply at first the surge of euphoria he felt at being called a good boy had made him cum. 

Pulling his maw away from the cock (it took a good deal of effort.) Joker panted a bit before replying. “Yes! Yes I want…. To be your dog!” Joker said, nuzzling the werewolves cock smearing his face with leaking pre-cum. “I’ll be your good boy!”

“Turn around and beg for it.” the Werewolf commanded before letting go of Joker.

Joker didn’t hesitate to obey. Every inch of his body was telling him that this is what he wanted.  Turning around he lifted his tail and his hips showing off his ass for his master. “Please make Joker your good boy! I promise to keep you warm and happy! I’ll take your cock whenever you want! I’ll wake you up with sloppy doggie blowjobs and clean up the mess! Just please please take me! Make me your bitch and knot me hard!” just thinking about doing the things he was saying had Joker’s cock dripping. 

“Well I suppose that does deserve the treat.” the Werewolf said leaning over Joker the tip of his cock pressing against Joker's ass. The former phantom thief wagged his tail in reply. The Werewolf pushed into him all at once and Joker moaned with delight as he was claimed. He whimpered and whined as his ass was taken by his master pounded over and over. Joker felt a maddening bliss wash over him as his collar was grabbed pulling him back against the Werewolf. Joke came as his master’s knot filled him for the first time. The Werewolf howled in delight as he came flooding Joker with warmth and feeling of rightness. 

Any lingering desire to return to being human left Joker in the week that followed. Keeping good on his promise to serve as a love toy for the Werewolf drowned him in the pleasures of being a dog. He came to love waking his master with oral sex, to the point where Joker often had to clean up his own cum from the act. Joker found the Shadow hounds and cognitive dogs were good company as well and it amused his master to no end watching Joker get mounted by them servants. Joker only  got to top one of the Shadows once and he had loved every second of it. The cognitive dogs welcomed him to their activities and he found the girl dogs were just as fun as the guys. Joker barked and howled and begged learning every command a pleasure. Within two days he couldn’t remember why he wanted to be human again. The best part though was his master’s cum getting to lick it up or slurp it down was one of his favorite activities.

After that first week of training though his master directed him to go out into the real world and be Lyle's pet. Joker wasn’t sure why Shadow Lyle wanted that but he did as instructed. Leaving the metaverse behind was only possible because the master willed it to be so. Joker traveled  as close to the dog shelter as he dared and then simply hopped in Lyle’s car as the man left work. The trip down the road made Joker nervous but thankfully it was also short. From there following Lyle to his apartment had been a piece of cake. When Lyle had opened the door to his apartment Joker simply bolted inside. 

Lyle had reacted to the strange dog entering his home with confused delight. Smiling as he checked the collar around Joker's neck. Lyle had gone slightly pale at first reading the collars band but then had laughed, declaring that there was no way the phantom thieves would come for him. With no owner to be found Lyle instantly declared that Joker was his, a declaration that earned him a big slobbery dog kiss. One that quickly got Joker to realize just how much Lyle loved dogs as the human kissed back. Very rapidly the dog found himself plucked from the ground, escorted to the bedroom and laid on the bed with his belly up. 

Nervous about this new interaction as Joker was, he was still excited about the prospect of satisfying his master’s carnal needs. He was a good dog and good boy’s were always horny.  Joker’s canid cock slid from his sheathe as he watched Lyle strip down and lube his own cock. Lyle grinned as he took hold of Joker's hips. 

“Oh you are a good boy aren’t you?” Lyle asked as he pushed the head of his cock into Joker. Joker gave a bark of agreement as Lyle pushed more of that cock into him, loving the feeling even if it was different from the canid members he was used to. Lyle was trying to be gentle but clearly needed it too much to hold himself back. Joker loved it all the same cumming on his belly as his tail wagged along the edge of the bed. He leaned up to lick his master's face and whimpered with delight as Lyle stroked his cock with one hand squeezing and teasing his knot till he came again. Lyle came a bit quicker than Joker would have liked. But the feeling of the humans warm cum stuffing him made him too happy to complain.

 That turned out to only be round one though, a scant four minutes later and Lyle was ready to go again. Joker laid on the bed back legs dangling in the air as he was taken once more cumming on to the bed spread with delight. Round two took a bit longer to wrap up but when it did Joker was sure Lyle had a round three in him. So as Lyle had laid out on the bed Joker simply stood up and began licking his cock and balls loving the mix of sweat and cum on both. Joker was petted and praised as he slurped on his master's lovely length which of course had Joker cumming once more.  Perhaps Lyle sensed Joker was smarter than an average dog because Joker couldn’t imagine what happened next.

“Good boy get on that cock and ride me hard.” Lyle commanded and Joker had no reason to disobey standing over the human he tried and failed to get that cock back in him but it wasn’t until Lyle helped guide the dog's ass onto his cock that joker succeeded. Joker yiped with pleasure as he rose and fell on his master’s cock loving the feeling of controlling the tempo and submitting at the same time. “There we go, you're not just a good boy, you're the best.” Lyle praised as he lovingly stroked Joker’s muzzle. Joker was so pleased at the kind words he started cumming again except this time it was a dry orgasm as he was totally spent. His orgasm earned him another filling of cum from Lyle as his ass milked the human's cock. They both fell asleep just like that a dog in his owner's arms.

For the last few weeks now Joker had been a good boy learning all the ways to keep Lyle happy and horny. Where to use the bathroom, how to get cleaned, where the food was, how to beg properly, and perhaps most importantly how to signal for playtime.

----

Joker snapped back to the present as he was taken to a back room of the shelter.  He was  escorted into one of the back rooms that was used for private viewings. There in front of him was a slender  orange lightly furred lab with a black and green collar that read Oracle. Joker tilted his head as the other dog pressed against the glass that separated them. He could swear he knew this dog from somewhere. Lyle leaned down, unleashing Joker.

“Hey! Let me out!” she barked as Lyle opened the door and shoved Joker inside. As he was pushed in, Joker realized two things, the second far more important than the first. Firstly, this dog was Futaba Sakura, possibly having been changed just like he had. Secondly she was in heat, her scent carrying the fact straight to Joker's brain.

“Okay Joker, I want you and Oracle to get along and make me some puppies.” Lyle said before taking a seat nearby. “Help her be a good girl just like you.”

“Puppies!” Joker woofed excitedly tail wagging as he got behind Oracle. He grabbed hold of her collar with his teeth as he began to hump her rear end. 

“Wait Joker?!?” she whined as his cock mashed up against her spade, the tip slowly emerging and sliding into her. 

“Be a good girl Futaba.” Joker growled as his cock filled her. Joker enjoyed the feeling of her hot sex parting around his cock the dripping spade just begging to be fillled. Oracle offered no resistance; she whimpered and whined but Joker knew that those sounds were pleas for more and he obliged. Fucking Oracle was a real treat and he would have to thank Master for it later. Letting go of Oracles collar he used his forelegs to pull her hips back against him he couldn’t wait to feel her tight spade squeezing his knot. 

“Joker… ha  ha don’t…  I'll… get pregnant!” Futaba howled between bouts of panting. Joker was not deterred in the slightest if anything the thought made him work harder.

“That’s the point Oracle!” He howled as he finally felt his knot sink into the eager depths of her sex. “Be a good girl and give me lots of pups!” he howled again as his knot swelled to full locking him within her as he started cumming. They both howled and even if Oracle wasn’t ready to admit it she was enjoying being bred, Joker could tell by the way her sex milked him for every last drop. Turning he saw the master watching them with a big smile on the human's face and Joker knew that he had done right.
