The rays of Celestia’s sun beat down upon Cadance’s face, causing the Alicorn princess to stir from her slumber.

Blinking the last remnants of sleep out of her eyes, the princess of love smiled when she felt her husband’s warm body pressed up against her own and turned around to face him.

“Good morning honey.” Cadance whispered

Onyx softly woofed back at his spouse, tongue flicking out to brush up against Cadance’s lips in a good morning kiss.

The Alicorn chuckled at the affectionate gesture. “Looks like somebody slept well.”

Onyx woofed again and attempted to rest his head on Cadance’s chest, only for the princess to push him away and sit up in bed.

“I’m sorry my love. As much as I’d love some morning cuddles, we still have a kingdom to run.” Cadance replied.

The Great Dane whined, head drifting lower to brush up against the large bulge on her belly. Princess Cadance could hardly believe that the day they’d become parents was almost here, it seemed like only yesterday they were tying the knot in holy matrimony and then literally tying the knot on their honeymoon. Now they’re about to start a family together after two years of marital bliss.

They were both excited of course, Onyx probably more so than Cadance; she was already familiar with the joys of motherhood thanks to Flurry Heart but this would be the Great Dane’s first born, the prospect of becoming a father was something that brought joy to his big doggy heart.

‘I just hope Flurry Heart likes her new siblings.’ Cadance thought to herself, placing a hoof on her pregnant belly. ‘All three of them.’

The one downside to being married to a dog was that by changing her biology to allow them to reproduce with one another, Cadance was going to bear a litter of puppies instead of a single foal. Thank Celestia there were only three, she didn’t know if she could handle popping out six at once.

In any case, the doctor said Cadance’s pups would be due any day now and to be ready for their arrival. Frankly the anticipation was killing them but Onyx and Cadance remained patient; waiting a few more weeks was no big deal when they’d have years to enjoy all the ups and downs that came with raising triplets. It was going to be wonderful.

‘I wonder if they’ll look more like me or their father. These are the first dog/pony hybrids in history.’ Cadance thought to herself as Onyx continued nudging her stomach.

The Great Dane’s head they slowly brushed up her chest, coming to a rest on her neck where he started softly licking at the exposed flesh. Cadance humming in approval as she tilted her head back to give Onyx better access to her throat.

“Well, maybe a little cuddling couldn’t hurt.” Princess Cadance said.

As she laid back down, allowing Onyx to climb on top of her and engage a kiss. The bed room around them started to blur, swirling in a mess of colors that grew more and more chaotic by the second.

Until finally, Cadance woke up for real.

***************

Princess Cadance stirred in her sleep, the pleasant dream she was having of domestic life coming to an abrupt end when she felt a heavy weight resting on her stomach and something wet and warm brushing up against her face.

Opening her eyes, Cadance was greeted by Onyx’s smiling face. The Great Dane laying down on top of the alicorn’s body and giving her a slobbery kiss.

Suddenly Cadance got a weird sense of deja vu and instinctively checked her stomach for a lump only to see that it was as flat as it usually was.

Frankly she didn’t know whether to be relieved or disappointed at that fact, but chose to address those feelings later and focused on the large dog currently drooling all over her. More specifically getting him off of her.

Seizing his collar in her magic, Cadance gently pulled Onyx away from her face and dragged him off the bed. Much to the Great Dane’s displeasure.

But Cadance ignored the sad whines coming out of the Great Dane’s throat and sat up in bed, rubbing some the leftover sleep out of her eyes. Somewhat confused by her latest wake up call.

‘How did Onyx get into my- oh Celestia that’s right…’

With her sleep induced haze gone, the memories of last night came flowing into Cadance’s mind and she couldn’t help but cringe in response, pink face turning red in equal parts shame and embarrassment.

‘First I French kissed him and then I gave him a blowjob?! WHAT IS WRONG WITH ME?!’ Cadance lambasted herself. ‘Ignoring the fact that it’s bestiality, I’m a married mare! With a daughter and a husband! A husband who’s dick is nowhere near as big as-GAH!’

Cadance smacked a hoof against her forehead, trying to dislodge those deviant thoughts. She was not sexually attracted to a dog! She wasn’t!

It didn’t matter if Onyx was an amazing kisser, it didn’t matter if he had a massive cock, and it didn’t matter that his mere presence brought about a stirring in her loins. Cadance did not want to fuck-

The alicorn’s thoughts came to a screeching halt when she felt a cold nose press against her clit, hot breaths puffing against her mound.

Head snapping down, Cadance gasped when she saw that Onyx had wiggled his top half under the blankets and was now pressing his head between her legs.

“Down boy! Sit! Heel!” Princess Cadance cried out.

Before Cadance could even get the chance to create some distance between them through physical means, Onyx unleashed his tongue upon her and obliterated any rational thought the princess may have had.

Cadance slammed her head back against the pillow behind her, back arching in response to the sloppy licks running over her pussy. The ruler of the Crystal Empire moaning and groaning like a whore the entire time.

Onyx was eating her out with far greater passion than he had before, having been spurred on by the events of the previous night to show his bitch how much he adored her and get some of her delicious essence in the process. The Great Dane really did love the taste of her pussy.

But before Onyx could truly savor the flavor of the pony squirming against his powerful tongue, the sound of a hoof knocking against the bedroom door interrupted the scene.

“Princess Cadance? Your Highness? Are you in there?” A female voice came from the other side.

Panic shooting through her body, Cadance scraped up what little mental fortitude she could and shoved Onyx away from her crotch with her magic before tumbling out of bed, scrambling for the door the moment she hit the floor.

“Yes?! Yes what is it?” Cadance exclaimed, peeking at the castle maid through the slightly open door.

The Pegasus’ visage twisted into a look of concern. “Ma’am are you feeling alright? You look quite flustered.”

Cadance nodded. “Oh I’m fine, completely fin-EEEEE.”

Apparently Onyx didn’t realize the seriousness of the situation nor why his lover had suddenly spurned his advances like that, because while Cadance was preoccupied with the intruding servant, he had decided to come padding up behind the princess and start licking away at her pussy once more. With a castle maid standing only a few feet away from both of them.

“My lady?!”

“Sorry! Sorry! I think I pulled my wing a little when stretching it out.” Cadance lied, trying to ignore the sensations in her rump. “Everything’s normal! Nothing to concern yourself with!”

“If you say so. Anyways, I just wanted to inform you that blah, blah, blah-“

The Crystal pony’s words completely stopped registering with Cadance, her mind having become too preoccupied with the attention Onyx was giving her. It took every ounce of willpower she had to maintain a straight face in that moment, smiling and nodding like she was actually paying attention to what the servant was saying.

Cadance tried to push Onyx away with one of her hind legs to hold off a potential disaster, but the dog refused to be deterred and resisted every attempt to deprive him of his delicious treat. Thus Cadance was forced to simply stand there and take it, hoping and praying that the servant would finish up before she reached a climax; but with the way Onyx was getting in there, that task was becoming exceedingly difficult.

‘Sweet fucking Celestia, that dog is eating me out better than Shining Armor ever could.’ Cadance thought to herself.

With her willpower on the verge of breaking, Princess Cadance decided to cut the conversation she was locked into short before her infidelity and act of bestiality was discovered.

“L-look can you-” Cadance gasped. “Can you please get to the point?!”

“Oh, apologies your highness; I do have a nasty habit of droning on now and then. Well to make a long story short, you’re relieved from your royal duties for the day.”

That was enough to distract Cadance from the feeling of Onyx’s tongue jammed in her snatch, albeit temporarily.

“W-what?”

“Don’t misunderstand, you aren’t being reprimanded. It’s just that the nobles who have appeared in your court for the last few days have reached an agreement amongst themselves, the remaining paperwork can be processed by the other servants, and the snow storm that moved past the barrier has resulted in something of a snow day for the kingdom. Essentially you have the day off Princess, I would take advantage of it if I were you since you’ve been working so hard recently without your husband around to ease such a burden.” The maid explained.

Cadance was utterly bewildered. She never got a day off unless it was planned out far in advance, even then there was the chance that some crisis or misadventure would pop up and ruin whatever opportunity she had for some rest and relaxation. But now the princess was having one dropped right onto her hooves out of nowhere, it was strange to say the least.

‘Oh well, don’t look a gift horse in the mouth as they say.’ Cadance thought to herself before addressing the maid.

“Thanks for letting me know. Is there anything else?”

The mare shook her head. “No that was all, unless you have something you need me to take care of. Perhaps straightening up your-” Cadance’s hoof shot out and shoved the crystal pony back when she moved towards the door.

“NO! No, there’s no need for that! You’re dismissed!” the princess yelped, feeling Onyx’s tongue forcefully drawing out an orgasm from her.

“Oookay then…” the mare said, shooting Cadance an odd look as she departed.

The princess of love then slammed the door shut and pressed her face up against the Crystal surface, finally letting the climax she had been holding back for the last few minutes come flying out now that it was safe to do so. Cadance screaming to the high heavens with pure euphoria shooting through her body, pussy spraying sexual fluids all over Onyx’s face like a fire hose; the sheer force of Cadance’s orgasm actually startled the dog who widthdrew his tongue and stumbled back with a whine, letting the rest of Cadance’s mess fall to the floor where it formed a sizable puddle around her hind legs.

After a solid minute of orgasmic pleasure, followed by a few additional minutes of recovering from such an earth shattering climax where Cadance tried to catch her breaths with heavy pants, the pony princess turned around to glare at Onyx.

“Damn it Onyx! I know you really like me but you almost got us- WAIT NO!” Cadance exclaimed.

But her order fell on deaf ears and Onyx started shaking himself dry, sending drops of Cadance’s feminine essence flying everywhere alongside the drool dripping off his jowls. Fresh bodily fluids rained down on the surrounding area; hitting the floors, the walls, the furniture, and of course Cadance herself who tried to shield her body from the incoming mess.

Onyx eventually came to a stop, determining that the moisture on his fur had been sufficiently expelled, only to notice that a thoroughly soaked Cadance was now glaring at him with a heavy frown upon her lips.

“Bad dog! Bad! Look at what you did! This whole place is a mess!” Cadance ranted. “I thought you knew better!”

The Great Dane lowered his head, tail tucking between his legs and an ashamed whine coming up from his throat. But even the kicked puppy act wasn’t enough to quell Cadance’s anger.

“Don’t give me that look, you aren’t charming your way out of this mister. You’re going to lay on your bed and think about what you did!” Cadance said in the same tone she’d use to scold Flurry Heart.

Onyx padded past Cadance, walking over to the small dog bed that Shining Armor had put in their room (one of several in the castle so the dog could choose to spend the night with Flurry Heart or by himself if he so wished) and plopping down with a sad huff.

Seeing that Onyx had been properly reprimanded, Princess Cadance nodded in satisfaction before heading to her private bathroom to scrub herself down. She could already feel patches of her coat growing stiff as the pussy juice and slobber began to dry; the icky feeling made Cadance shiver in disgust.

Thankfully a hot shower solved that issue within minutes and Cadance allowed herself to enjoy the feeling of warm water running down her form, doing a bit of deep thinking while she had the opportunity.

First and foremost, she had to put an end to whatever was going on between her and Onyx. While Cadance was understandably upset with the dog’s actions, she knew that she wasn’t entirely blameless either.

Onyx might have made the first move but Cadance was the one to escalate matters by going down on him, letting her lustful instincts get the better of her. Now Onyx had gotten the wrong idea and thought the alicorn was attracted to him…

‘Which I’m not!’ Cadance thought to herself, perhaps with a bit too much force.

Regardless of her feelings, the fact of the matter was that Cadance couldn’t let this affair go any further. She had to put her hoof down and establish proper boundaries with the Great Dane, otherwise he would only get more insistent with his advances until something went horribly wrong. Like him trying to mount the alicorn in a more public setting.

Ignoring the mild shiver of pleasure that idea invoked within her, Cadance began ruminating on how she could properly set those limitations. Avoiding Onyx was obviously out of the question; not only did his role as a beloved family pet in the eyes of Shining and Flurry make that impossible to achieve in the long term, but the princess of love had developed some level of genuine affection for Onyx and wanted to keep him around.

‘Hmmm. I do have the day off.’ Cadance internally said. ‘Maybe if I spend it with Onyx, the two of us going around town, then I could get the opportunity to set some proper boundaries; teach him what is and isn’t appropriate behavior.’

The princess of love turned off the water and stepped out of the shower, picking up a towel in her magic to dry herself off.

“Yeah, taking Onyx out for a walk sounds like a great idea. I could bring him over to that park Flurry loves so much, maybe play fetch with the big guy.” Cadance said to herself.

With a plan of attack in mind, Princess Cadance quickly sponged all of the water off of her body before going through the rest of her morning routine: brushing her hair into its usual neat and refined style, applying her makeup, and checking for any stray blemishes in the mirror. Once Cadance felt satisfied with her appearance, she returned to the bedroom to set her idea in motion.

Onyx hadn’t moved so much as an inch since his mistress had entered the bathroom, the black furred canine was still curled up on his bed with a sad look in his eyes. The pitiful scene before her only strengthened Cadance’s resolve as she moved towards the dresser.

A brief search through the drawers produced the leash Shining liked to use whenever he took Onyx out, the jingling of the leather rope quickly getting the Great Dane’s attention.

“Wanna go for a walk Onyx?” Cadance said, waving the leash around in her magic.

Onyx’s tail started wagging, tongue flopping out as he rose to his paws and prepared to bound over to Cadance. Only for the alicorn to hiss at him before he could get the chance.

“Hey! No! No jumping on me! Sit!”

Onyx quickly obeyed, sitting back on his rear end and keeping his body still apart from his tail which was still wagging behind him in excitement.

Letting out a breath of relief, Cadance cautiously approached the large animal and clipped the leash around his collar, giving the rope a few experimental tugs to ensure that it was on properly.

“There we are! Now let’s get going Onyx.” Said Cadance.

“Woof!” Onyx exclaimed, bringing his head forwards and licking Cadance’s lips before he was promptly pushed away.

The princess groaned as she wiped the slobber off of her face, getting Onyx to ease up on the expressions of affection might have been harder than she thought.

***********************

Cadance was a little nervous about taking Onyx for a walk, Shining or one of the servants had always handled this task so this would be her first time taking on such an ordeal. The sheer size of the Great Dane meant that she’d have a hard time holding him back if he decided to take off running at any point and fully anticipated being comically dragged through the streets of the Crystal Empire, keeping a death grip on the leash wrapped around her hoof as Onyx chased after a squirrel or something.

But instead of a humiliating slapstick scene, Cadance was treated to a lovely walk with the family dog where he conducted himself with the utmost zen and maintained a comfortable pace for his owner as they trotted along the sidewalks and roads. No mishaps or misfortune to be seen.

It was quite pleasant and apart from a few crystal ponies stopping them on the street to either compliment Cadance, pet Onyx, or both, the princess and the Great Dane managed to arrive at their destination with little delay.

While it wasn’t as impressive as some of the parks in Canterlot, the Crystal Empire park was still an impressive sight to behold. The park had been built up as one of the many public works projects involved with brightening up the Crystal Empire as a sort of departure from its darker past.

The entire plot of land was filled with wide open fields, wonderful Crystal statues, a large variety of trees and shrubbery, and plenty of facilities for use by the public such as playgrounds and ponds. Even with the cold weather and snow blanketing the landscape, there were still plenty of ponies out and about enjoying everything the park had to offer.

Unfortunately those same ponies were the ones to throw a massive wrench into Cadance’s plans.

The ruler of the Crystal empire had barely taken two steps into the park before a shrill and excited voice suddenly cut through the air.

“DOGGY!”

Looking over in the direction of the noise, Cadance saw a very young unicorn colt galloping up to them with almost maniac excitement directed at Onyx; the Great Dane shifted nervously behind Cadance and the pink alicorn positioned herself to block the smaller pony from any physical contact with Onyx, not wanting a public incident to occur because a foal didn’t know the meaning of personal space.

But before the colt could get within petting range, a green glow suddenly engulfed their body and lifted them off the ground; their tiny legs flailing around in the air as a second, much older unicorn approached.

“Emerald flare! I thought I was perfectly clear when I told you to stay with the group!” The unicorn barked.

“But Mr.Borealis-“

“No buts young man! March your flank back to your classmates or you’ll be in after school detention all week!” The unicorn said, turning to Cadance. “I am so sorry for this disturbance, your highness. You know how foals can be sometimes.”

“It’s alright. No harm done.” Cadance replied.

“Still, that doesn’t excuse his behavior.” Said Mr.Borealis, motioning to the foal still floating in the air.

“But I just wanted to pet the dog!” Emerald Flare protested.

“Emerald Flare, you can’t just run up to random dogs and start petting them! You could have gotten hurt by that beast!” Mr.Borealis exclaimed before looking over at Cadance again. “No offense.”

Cadance shrugged. “None taken, Onyx is a sweetheart but sometimes he doesn’t understand how big he is so it’s a reasonable concern.”

“See! Besides, even if the dog looks friendly you still need to get the owner’s permission before you can touch them!”

“I’m sorry professor.” Emerald Flare mumbled.

“Don’t apologize to me. The princess is the one that’s owed an apology.”

“I’m sorry princess. I won’t do it again.”

“Apology accepted.” Cadance replied, before glancing at Onyx. “Although, you can pet Onyx if you want to.”

Emerald Flare looked up. “Really?”

“Sure! Just be gentle and try not to scare him.” Cadance said.

A brief look was all it took for the professor to place his student back down on the ground, the smaller unicorn walking up to Onyx with far more restraint than before. Once he was in front of the dog, Onyx lowered his head to sniff at Emerald’s mane before licking the unicorn’s cheek.

“He likes me!” Emerald giggled as the large tongue stroked against his face.

“Try scratching behind his ears, he loves that.” Cadance suggested.

Emerald did just that, standing up on the tips of his hooves to reach the top of the dog’s head and Onyx started panting in joy when he felt the pleasant scratching sensation, eventually rolling onto his back to ask for a belly rub which the foal was happy to provide with more joyous laughter.

“Alright Emerald Flare, that’s enough. We really need to be going.” Professor Borealis said.

“Aww! But can’t I play with him a little longer?” The foal whined.

“Unfortunately no, the rest of the class is waiting for us and we can’t hold them up any longer.”

Emerald bowed his head in disappointment and removed his hooves from Onyx, who was equally disappointed by his petting session being cut short.

“Wait, are you all on a field trip today?” Cadance asked.

“Yes ma’am. We’re taking the foals and fillies around the empire to look at important historical sights, teaching them the history behind them.” The professor explained. “Although we came to the park for a bit of a break, let the class have lunch and spend a few hours playing before getting back to the tour.”

Cadance felt Onyx brushing up against her flank, the dog whining and whimpering with a pleasing look in his eyes making it very clear what he wanted. With Flurry Heart being absent for the last few days, Onyx hadn’t had anypony to play with and was desperate for some sort of excitement. A crowd of schoolyard ponies at the park seemed like the perfect avenue to have that desire fulfilled.

After a moment’s hesitation, Cadance called out to the teacher. “Can we come along with you?”

“Pardon?”

“Well we didn’t have much planned for today and I’m sure Onyx would love to spend an hour or two playing in the park with your class. Poor thing has been cooped up in the castle for the last two days all by himself and could use the excitement.” Princess Cadance explained.

“Are you sure that’s safe? He is rather big.”

“Oh yes, Onyx is very well trained.” Cadance said. “And I’ll be right there to keep an eye on him in case he gets a little too excited.”

“Be that as it may, I still don’t want any of the foals in my class to accidentally get hurt roughhousing with that beast.” The professor replied.

Suddenly Emerald Flare piped up. “Oh please professor Borealis, please let them come! I really wanna keep playing with the dog! We’ll be gentle and careful, I promise!”

“Alright, fine. I suppose as long as the Princess is keeping an eye on things there couldn’t be too much harm in letting her dog join us for lunch.” Professor Borealis said. “Right this way your highness.”

A short walk along the path soon brought them to the rest of the group who had a rather mixed reception to Onyx’s presence at first: some immediately got excited like Emerald Flare and ran over to start lavishing the dog with affection, while the more timid members of the group approached Onyx cautiously or kept their distance entirely. But Onyx’s friendly demeanor quickly won them all over and the entire class was happily frolicking through the snow with the Great Dane, it was downright heartwarming.

Since Onyx was preoccupied with the younger ponies, Princess Cadance took the opportunity to rest her hooves on a nearby bench. The alicorn took a seat next to professor Borealis who was watching his class at play with a smile on his muzzle.

“Quite the dog you have there.” The professor remarked.

“Thank you, my husband picked him up from a shelter a few months back. I wasn’t too keen on letting him bring a dog into our home at first but Onyx has really grown on me recently.” Princess Cadance replied.

“I can only imagine how much effort it took to properly train such a large animal.”

“Actually Onyx has been well behaved since the day he came into our lives, apart from being a little overly affectionate at times, very docile and obedient. Whoever his previous owner was they did an excellent job with his training.”

“Huh. Well he certainly seems to be particularly good with foals.” Professor Borealis said, watching as a trio of colts played a game of tug of war with Onyx that they promptly lost all with smiles on their faces.

“Yeah…yeah he is…” Cadance remarked as she felt herself getting lost in thought.

Not many ponies know this, primarily because most never think to ask, but the number one trait Princess Cadance finds to be the most desirable when it comes to a romantic partner is being good with kids. Whether it was some latent nostalgia for her babysitter days or perhaps some primal instinct in her brain being the cause, Cadance just couldn’t help but be drawn towards those who were able

And looking out at the snow covered field in front of her, watching Onyx lightly roughhouse with the foals climbing all over him to their delight with a big smile on his face, it caused a bit of warmth to flare up in the alicorn chest alongside a deep blush that made her look like a school filly with a crush. Thank Celestia nobody noticed her sudden change in demeanor…although the stirring in her loins was a different matter entirely

Draping her tail down to hide her moistening pussy, Cadance suddenly became aware that the professor was saying something to her.

“I’m sorry, could you repeat that?” Cadance asked.

“I said, have you considered doing some breeding with him?” the professor asked.

The alicorn’s face went flush, momentarily terrified that Borealis had noticed her deviancy. “I beg your pardon?!”

“I have some relatives who work in breeding programs and dog shows that would absolutely love to use him as a stud, what with him still being ‘intact’ as it were.”

“Oh, you were talking about show dogs.” Cadance replied, letting out a breath of relief.

Professor Borealis gave the princess an odd look. “Of course, what did you think I was talking about?”

“Don’t worry about it. I’d like to know why your relatives would be interested in Onyx at all.” the princess said with a tone of feigned interest.

"Well I could be wrong about this but based on looks alone, your dog might be a purebred Great Dane and a rather well built one at that. I’d assume you don’t have any official documentation since the prince adopted him from a rescue kennel, but a bit of blood work and testing could solve that issue right away. If he does end up with a pedigree I could certainly put you in contact with the proper individuals looking for him to sire a litter or two. His temperament would make him the perfect stud.”

“Hold on, I can’t just give Onyx away like that. He’s part of the family and my husband, my daughter, and I really like having him around.”

“Give him away? Oh perish the thought, you’d simply be lending him out to other ponies for breeding purposes. In fact you might not even need to make arrangements to see a breeder if you want to go the route of artificial insemination as opposed to the natural way.” The professor explained.

“And what exactly would the natural way entail?” Cadance said, now genuinely interested…for all the wrong reasons.

“What it sounds like: two dogs mating with each other like they would in the wild.”

“There has to be more to it than that.”

“Well…” Professor Borealis paused to collect his thoughts. “A breeder would come down to visit you with a bitch in heat, ready and waiting to be bred by a stud which would be Onyx in this case. Once they’re properly guided into position, Onyx would mount his partner by clasping his forelegs around her midsection and thrusting until penetration and ejaculation take place. At which point the knot, a swollen section of the canine penis, ties the two together and the stud turns around so that they’re rear to rear until they separate naturally over the course of ten to thirty minutes. This process repeats every other day or so for about two to three mating sessions and after that it’s a matter of simply hoping for the best.”

Princess Cadance just stared at him, causing the unicorn to nervously squirm around in his seat from embarrassment.

“My apologies, I got a little carried away there.” Professor Borealis coughed.

“It’s fine but you seem particularly well versed on this topic.” Cadance replied.

“Like I said, a lot of my relatives are dog breeders. You tend to pick up a few things when you’re around such ponies.” the professor said before pulling out a watch. “Dear me! Has it been that long already?!”

Professor Borealis hopped up from the bench and dusted himself off. “Sorry I have to cut this conversation short your highness, but we really must be going or we’ll be late for the museum tour. COME ALONG EVERYPONY! IT’S TIME TO GO!”

A chorus of disappointed moans came from the class.

“No complaining! You should count yourselves lucky I was willing to let you play with Princess Cadance’s dog for so long! So hop to it!” The unicorn said before turning towards the alicorn. “Do think about what I said. Purebred Great Danes are rather valuable and some of the breeders may be willing to give you a few pups from the litter in return for your cooperation, perhaps as a gift for a family member or friend of some kind.”

Cadance nodded. “I’ll keep that in mind, professor.”

“That’s all I ask. Have a wonderful afternoon princess.”

After getting their saddlebags packed up and Onyx’s leash secured around his collar once more, Professor Borealis’ class bid Cadance farewell and trotted off into the rest of the city. Leaving the alicorn princess’ mind buzzing with all sorts of ideas as she resumed Onyx’s walk…not all of them good.

The alicorn’s eyes flicked down to the area between Onyx’s legs; the large balls hypnotically swaying with every step, Cadance biting her lip in response. The discovery of the Great Dane’s well endowed status remained fresh in her mind, sending a small spark of pleasure across the neurons. One that she swiftly tried to ignore.

Cadance tore her gaze away from Onyx’s genitals and refocused on the task at hand. There were still several other stops she wanted to make around town, which meant there would be plenty of opportunities to get her mind off these lustful impulses and return to some semblance of normalcy.

“Just focus on the walk. Don’t think about Onyx’s dick, just focus on the walk.” Cadance muttered to herself.

Hopefully a bit of fresh air and a change of scenery would help distract the princess from the growing attraction for Onyx which had taken root in her heart.

*******************

The door to Cadance’s room slowly creaked open, the aforementioned alicorn walking in with an unreadable expression before flopping face first onto the bed; a tired moan emanating from her throat.

Her plan had completely backfired, spectacularly so. Instead of putting a healthy distance between the two of them, Cadance and Onyx had only been brought closer together with the princess’ taboo feelings for the Great Dane becoming stronger.

After they left the park, the two of them were subjected to a long string of coincidental events that showcased some of Onyx’s more attractive qualities: goofily trying to lick a dollop of whipped cream that had gotten stuck to his nose from a special dog treat, adorably begging Cadance to hold his paw in her hoof when they were sat at an outdoor cafe, and even saving an older mare from a runaway cart by tackling her out of harm’s way in a decidedly heroic fashion. It felt less like Cadance was taking Onyx out for a walk and more like they were going out on a date together.

The fact that she wasn’t bothered by such an idea made Princess Cadance disgusted with herself. The possibility that she was falling in love with a Celestia damned dog was one she didn’t even want to consider…and yet it was getting harder and harder to deny the feeling in her heart.

“Oh why did Shining have to adopt such a handsome and charming dog?” Cadance whined into her pillows.

Whilst Cadance was bemoaning her situation, she found her mind drifting to the dream she had last night. A hoof trailing down to rub her stomach, recalling the feelings of warmth brought forth by that domestic fantasy where she was carrying a whole litter of puppies.

Obviously ponies and dogs couldn’t breed, it was a biological impossibility. But then again so were ponies and other intelligent creatures such as dragons and griffins and they managed to find a way with a bit of magical assistance…something Princess Cadance was more than capable of pulling off as evidenced by that griffon and pony couple she helped last year, she even got a Hearths Warming card from them with a picture of their hybrid foal/chick and an expression of gratitude. The only question was if that same sort of magic could be applied to non-sapient creatures such as a Great Dan-

“Wait, what am I thinking?” Cadance muttered to herself. “I don’t actually want to have that dumb mutt’s puppies…do I?”

The sound of clicking nails against the crystal floor distracted Cadance from her conflicting thoughts, the alicorn looking over her shoulder to see Onyx padding over to the foot of her bed with his typical goofy smile.

Cadance sighed and turned away. “Leave me alone Onyx.”

Onyx’s smile disappeared and the dog tilted his head in confusion.

“I mean it Onyx. Go on, shoo.” Princess Cadance said.

Onyx didn’t leave, his obedience training being overridden by the feelings of genuine concern for one of his owners. Onyx didn’t know why Cadance was so unhappy, it didn’t make any sense when they’ve been having so much fun together for the last few days, but it didn’t really matter; all the Great Dane knew was that Cadance was sad and needed some cheering up.

So he attempted to do just that.

First Onyx padded closer to the bed and sniffed at Cadance’s hind hooves which were hanging slightly off the bed, gently lapping at the bottoms of the appendages as he often did with Flurry Heart to make her laugh. Unfortunately while that did elicit a small giggle from Cadance, the alicorn princess quickly pulled her legs away and scooted further up the bed.

Not to be deterred, Onyx followed after Cadance and hopped onto the bed with her. The alicorn rolled over onto her rear with her back resting against the pillows, giving Onyx an unimpressed huff before attempting to gently push him away with her magic.

Onyx fought against it however, increasing his proximity to Cadance until he plopped his head down in her lap while the top half of his body rested across her legs. The large dog sadly whining and snuggling into the soft surface, using every bit of charm he had to try and put a smile on her face.

Princess Cadance resisted for a few more minutes, trying to force Onyx off her to no avail, before finally giving up in exasperation.

“Alright fine, you can stay you big goof.” Cadance said.

A woof of satisfaction served as Onyx’s response, the Great Dane affectionately nuzzling Cadance’s stomach and crawling further into her lap. The princess could only chuckle at the display and brought her hooves over to start petting him.

She may have not been an animal whisperer like Twilight’s friend Fluttershy, but it didn’t take long for Cadance to realize that Onyx had noticed she was upset and went out of his way to comfort her. It was sweet…almost romantic actually.

‘I can’t remember why I didn’t like him before, Onyx is such a sweetheart.’ Cadance thought to herself.

Several memories from the last few months began running through Princess Cadance’s head: the day Onyx was brought into their home and immediately took a liking to the pink alicorn, how he demonstrated a great mix of intelligence and athleticism when running an obstacle course with Shining Armor, and how he protected Flurry Heart time and time again with the utmost loyalty. Each one causing Cadance’s body to heat up more and more.

Then Cadance thought back to the conversation she had with professor Borealis earlier, namely his rather detailed description of how the canine mating process went. She pictured Onyx hopping up to mount some random dog, thrusting against the bitch’s rear and burying his thick cock into her snatch until the knot locked the two of them together…and then Cadance imagined being on the receiving end of such treatment.

“I wonder what it would feel like?” Princess Cadance whispered to herself, looking down at Onyx who was happily panting in response to the alicorn’s affections.

There was still a rational part of Cadance that attempted to dissuade her from doing so, reminding her of her loving marriage and the daughter than had been produced from such a union, but it was a lot quieter than it had been earlier this morning. A lustful haze settled over the princess’ mind as her horn started glowing, a familiar pink sheen briefly flashing across her eyes.

“One time…I’ll do it one time to find out what it’s like.” Cadance said to herself. “Then I’ll put this whole weekend behind me and pretend it never happened. Just one and done.”

The ruler of the Crystal Empire moved Onyx off of her lap, softly pushing the Great Dane into a sitting position on the bed. Onyx whined in protest and tried to move back into the embrace, but a hoof upon his furry chest put a stop to that.

“Down boy. Sit.” Cadance firmly said.

This time Onyx listened, resting on his haunches and staring at Cadance with a look of curiosity.

With the weight of the one hundred and fifty pound dog removed, Princess Cadance was free to steel her nerves and prepare herself for the atrocity she was about to commit. The alicorn shifted around until she was seated in the same position as Onyx, the two creatures at eye level with one another. Unfortunately the Great Dane wasn’t in the mood as a lack of a visible red rocket between his legs revealed, but Cadance knew how to fix that.

The Princess of Love channeled up some of the magic that was her namesake and cast a mild charm upon Onyx to nudge him in the right direction without using any form of mind control.

The effect was immediate. Onyx started panting in excitement, tail furiously wagging behind him and cock slipping out of its sheath.

“T-there we go, t-that’s a g-good boy.” Cadance nervously stuttered out.

Redirecting her magic to Onyx’s growing erection, Cadance stimulated the throbbing organ with a magic based hoof job; her arousal growing as more and more of the dog dick slipped out into the open. Onyx kicking his leg out each time the aura hit a particularly sensitive spot, panting louder and louder all the while.

Once Onyx stood at full mast, knot and all, Cadance allowed her magic to dissipate and fell backwards onto the bed. The Great Dane growling from the sudden removal of his pleasure, until he saw Princess Cadance resting in front of him on her back.

The alicorn gulped and slowly spread her legs, presenting her moist pussy to Onyx in a decidedly sexual fashion.

“C-come on Onyx, don’t be shy.” Said Cadance, still holding a level of reservation about all this.

Onyx didn’t quite understand at first, stepping forward and pushing his head between Cadance’s legs; gently sniffing and licking at her pussy like he had before. While Cadance certainly appreciated the treatment, the light squeak of pleasure she made serving as proof of such, she wanted to get to the main event sooner rather than later.

So Cadance grabbed Onyx’s collar in her magic, pulling him upwards until his muzzle was practically touching her snout and his body was comfortably resting on top of hers. That’s when Onyx finally got a clue and started rolling his hips against the alicorn beneath him, doing his best to find her pussy in spite of the unconventional position…which unfortunately wasn’t good enough as Onyx only managed to grind against Cadance’s outer lips.

After several missed thrusts, Cadance grew impatient and decided to give Onyx a helping hoof. Her horn lit up once more and engulfed the dog dick in blue energy, maneuvering it around until the tip was sitting just on the edge of her entrance.

The very moment Onyx felt wetness against his cock, he thrust forwards and crammed his entire length into Princess Cadance; thus sealing her fate as a dog fucker.

Thankfully being a mother meant that Cadance’s vagina was fairly loose, making Onyx’s dick an easy fit despite the canine’s massive size. But that didn’t stop him from completely filling her to the brim, inch after inch of throbbing meat disappearing into the alicorn’s body until the knot brought Onyx’s advance to a halt. For a brief moment Cadance swore she could feel the very tip of his cock brushing against her cervix.

They remained like that for a mere moment before Onyx let out a lustful growl and started thrusting into his new bitch, frantically sliding his cock in and out of her depths at a breakneck speed that quickly purged all rational thought from Cadance’s mind in a matter of seconds.

“Sweet bucking Celestia!” Cadance cried out, eyes snapping shut. “You’re even bigger than Shining!”

The sounds of their mating created a revolting symphony of lust: wet smacks echoing off the walls as their hips rhythmically collided against one another like the beat of a drum, Cadance’s euphoric moans and Onyx’s laborious panting serving as the chorus, and the creaking of the bed beneath the interspecies lovers rounded out the entire scene.

Eventually Cadance adjusted to the feeling of the large dog dick bashing against her inner walls and allowed for a bit of consciousness to shine through the fog of forbidden pleasures engulfing her mind, not enough for her to realize how utterly wrong this was of course but enough so that she was able to reopen her eyes and get a good look at her partner.

It might have been Cadance’s own carnal instincts talking but from where she currently laid, Onyx looked unbelievably handsome. His pitch black fur gleaming in the low light of the room, powerful muscles flexing each time he slammed his cock into her, a muzzle curled up into a look of pure focus and dominance with pearly white teeth clamped together, and a pair of beautiful brown eyes that gazed into her own in a rather intimate fashion. Cadance found her heart beating faster as her horn sparked up yet again and caused a certain aura to wash over both of them, strengthening their connection even further.

Then, unable to control herself, Cadance lifted her head up closer to Onyx’s own and gave his muzzle a tender lick. The great dane recoiled in surprise and momentarily slowed down his thrusts but Cadance simply giggled at his confusion.

“Come on Onyx.” Cadance seductively cooed. “Give your bitch a kiss.”

The princess of love planted another soft kiss onto Onyx’s snout and by then the dog seemed to understand what his lover wanted, tongue lolling out to return the gesture. Onyx lapped at Cadance’s lips a few times before the alicorn opened her mouth and granted the large canine tongue access to her maw all while Onyx continued to plow her pussy.

Unlike the previous kiss they shared, Cadance embrace Onyx’s advances and welcomed the presence of his muzzle pressed up against her own. The alicorn wrapping her hooves around the back of Onyx’s head to deepen the kiss further, moaning in delight as she felt his massive tongue dip into her mouth and brush up against every spot it could reach. Cadance tried to take some semblance of control of the situation but it was a fruitless effort; even if she wasn’t distracted by the wonderful cock thrusting into her at frantic speeds, her petite tongue was no match for the absolute monster currently filling her gob and thus the princess of love was forced to let Onyx take the lead in their little tongue tango.

Which she had absolutely no problems with.

The two of them went on like that for what felt like hours, Cadance and Onyx sharing a sloppy kiss with plenty of tongue action while never once letting up in their mating session; Onyx making his doggy dick quite comfortable within the confines of Cadance’s pussy, humping away at the silky smooth walls like there was no tomorrow.

‘Fuck me! If I’d known Onyx was this good in bed I would have done this a lot sooner!’ Cadance internally moaned.

The princess of love was experiencing levels of euphoria she never even knew existed, Onyx giving her the sort of pleasure that a mare like her could only dream of. Shining Armor may have set the bar high for sexual partners but Onyx had smashed straight through it with ease and proved himself to be a far better lover than the captain of the royal guard ever was.

It was a shame that Cadance wouldn’t be able to get an encore from Onyx, but she had promised herself that this would be nothing more than a one night stand. Come the next morning everything would return to normal and the princess of love would go back to her husband, regarding Onyx as nothing more than a regular pet as opposed to a lover. Cadance wasn’t looking forward to it but sadly her hooves were tied, all the princess could do was try and savor this moment of lust and carnality as much as she could before her affair with the beast came to an end.

So Cadance wrapped her hind hooves around Onyx’s rear and moved in time with his thrusts, helping the Great Dane sink his cock even further into her depths. In doing so, Cadance felt Onyx’s knot pressing up against her pussy and stretching out her folds with every impact. The alicorn thought back to what Professor Borealis said about the lump of flesh, how it was supposed to tie a canine to their sexual partner and make sure all their seed stayed inside of their bitch, and decided to get a firsthand experience of what it felt like to be knotted.

Soon enough Cadance felt an orgasmic release appear on the horizon and judging by the increased speed of Onyx’s thrusts, the Great Dane was nearly at a climax himself.

Cadance broke free from the kiss and moaned right into Onyx’s ear. “That’s it boy! Good dog! Very good dog!”

It wasn’t entirely clear if the dog understood Cadance or not but he started plowing her harder all the same. Getting his dick deeper and stretching the alicorn further, until his knot finally breached Cadance’s outer lips and wedged itself comfortably inside her vagina.

Princess Cadance let out an orgasmic scream, her entire body locking up as she came around the massive dog dick hilted inside of her.

Onyx wasn’t far behind, howling to the high heavens as he felt his cock burst and coat the walls of Cadance’s love tunnel with his seed. The large knot plugging her hole ensured that not a single drop of canine semen spilled out. A pointless gesture given the incompatible nature of their sexual organs but Cadance still enjoyed the feeling of being filled up like a balloon.

Once the flow of euphoric release came to an end, Cadance’s body went limp on the bed as Onyx let the last few ropes of cum spurt out of his dick.

The alicorn let out a whine of disappointment when Onyx stepped away from her and turned around to properly tie them off, stepping off the bed in the process, but she couldn’t fault him for following his own instincts. Amazing lover or not, he was still a dog. At least this gave her the chance to catch her breath and collect her thoughts.

‘Alright, you fucked a dog, you fucked a Great Dane and you loved every minute of it. Now that it’s out of your system you can put this weekend behind you and- Guhhh.’

Cadance’s thought process was interrupted when Onyx, clearly not one to savor the afterglow of a good rutting, began to pull his knot free from the embrace. This process would have taken longer but thanks to the somewhat loose quality of her pussy, Onyx slipped out of Cadance after only a few short tugs. A river of dog semen spilling out of the alicorn and forming a puddle on the bed sheets.

“Wow, you were really pent up weren’t you boy?” Cadance panted.

Onyx woofed.

“I’ll take that as a yes. Now let’s-“ the princess of love was cut short when Onyx padded forth and started nudging the side of her body with his head. “What are you doing?”

The dog didn’t give much in the way of a reply, he simply kept nudging Cadance until she rolled over onto her belly; the princess too exhausted from their recent sexual encounter to put up any resistance.

Glancing over her shoulder, Cadance’s eyes widened when she saw that Onyx’s dick was still rock hard and ready for action. The dog was clearly gearing up for a second round and that theory was soon proven correct when Onyx hopped back onto Cadance, draping his furry body over her own, and prepared to mount her in a mating position he was more familiar with.

“W-wait, we just did it Onyx! Down boy! Heel!” Cadance stuttered out, squirming under the weight of the animal.

But Onyx wasn’t listening, as far as he was concerned Cadance relinquished the right to give him orders when she submitted to his sexual dominance. Now his former master was nothing more than a common bitch and he was going to treat her as such…albeit in a loving and intimate way as one would with a traditional mate.

So the canine lined up his massive penis with Cadance’s entrance, perking up when he felt a wet hole against the tip and thrusting forwards to pound his bitch for the second time tonight.

What Onyx didn’t realize is that when Cadance was shifting around beneath him, desperately trying to buck him off, she ended up screwing up the Great Dane’s aim. Instead of slipping in to her well used pussy like intended, Onyx had crammed his dick square into the alicorn’s ass.

“OHHHH BUUUUCK! OH SWEET BUCKING CELESTIA THAT HURTS!” Cadance screamed.

Anal wasn’t something Cadance enjoyed. No particular reason why, it simply wasn’t her cup of tea. Shining Armor did get some enjoyment out of the practice, both giving and receiving, but out of respect for his wife’s needs it was reserved for special occasions: anniversaries, birthdays, hearth’s warming, and of course his graduation from royal guard academy. (They had nearly gotten caught in the act on that last one)

Now that policy had come back to bite Cadance in the flank, in a pretty literal sense too. Her anal ring stretched obscenely in order to accommodate for the dog cock being forced through her back door, contracting around the throbbing organ in protest. The alicorn had to grit her teeth just to cope with the blinding pain of having her rear end mercilessly pounded in such a manner.

She could feel every last inch of his dick pulsating inside of her ass, sliding in and out like a piston and forcing a gasp out of the alicorn with every thrust. Cadance felt like she was being split in half by the Great Dane, the burning hot meat tearing her relatively virgin ass wide open. She wanted to tell him to stop, or at the very least slow down, but unfortunately she could barely breathe let alone form a coherent sentence.

At least until Princess Cadance became acclimated to the feeling of her ass stretched by a massive canine cock, the pain slowly subsided and allowed lustful pleasure to take its place. The alicorn’s grimace of pain morphing into a whorish smile.

“Oh yeah.” Cadance moaned. “That’s it boy, fuck me like the beast that you are. Take me!”

Onyx barked and, without giving the alicorn princess any time to react, lunged forward and grabbed a chunk of her mane in his jaws, pulling her head back in a show of dominance.

Princess Cadance squealed with so much force that it nearly rattled the Crystal walls of her room. It was no secret that she liked things a bit rough sometimes and Onyx was being really, really rough with her; the Great Dane utterly ravaged her body in every conceivable way and soon the princess of love found herself losing herself to animalistic lust.

She loved this, she loved everything about what was happening right now. The feeling of being brought so low, the ruler of an empire being used as some drooling mutt’s personal cocksleeve, made Cadance feel so deliciously dirty.

Forget Shining Armor, forget her marriage vows, forget the very notion of this being a one night stand. Princess Cadance wanted nothing more than for Onyx to screw her brains out every single night from here on out, she wanted to be his bitch. The alicorn had completely fallen in love with the Great Dane mercilessly plowing her ass, her heart belonged to him now as did all of her holes.

Summoning up what little strength she had left, Cadance attempted to get back on her hooves and start fucking Onyx back but a firm tug on her hair followed by a threatening growl soon quashed that idea. Onyx was in control now and he wasn’t about to let the princess of love challenge his newfound authority over her.

Thankfully Cadance didn’t mind, the idea of submitting to this slobbering beast sent a spark of arousal through her form that she rather liked. So she simply laid down on her stomach and let Onyx have his way with her, gleefully enjoying the dog’s anal ministrations.

Of course with the tight hole milking his cock for all it was worth, Onyx couldn’t last long and he started to chase after his second orgasm of the night with vicious fervor. Making his alicorn partner moan even louder with his thrusts growing in both speed and intensity.

“Come on Onyx! Harder! I wanna feel your knot in my ass!” Cadance screeched.

Onyx snarled and doubled down on his pace, slamming into the alicorn at a breakneck pace; desperately trying to force his knot through the outer rim of her pucker. Until finally, with one final savage thrust, the Great Dane’s knot squeezed its way into Cadance’s tight ass and stretched the hole to its absolute limits.

Princess Cadance climaxed again right then and there, erupting in a long winded moan as the pleasure of being anally knotted washed over her; the last bit of love she held in her heart for Shining dying out in the process. Onyx had claimed the alicorn as his mate and there was nothing anypony could do to change that.

Speaking of the Great Dane, he reached his own orgasm when Cadance’s ass clenched around the entirety of his length and continued to slam his hips against her flanks as another load of cum flooded the princess’ rear end. Releasing her mane to utter another euphoric howl.

With that, Cadance and Onyx had reached the limits of their stamina and collapsed on the bed together. Onyx’s furry body provided a sort of comforting warmth to his equine mate who rested underneath him, sort of like a heavy weighted blanket. Cadance’s heart beating in time with the throbbing of Onyx’s cock.

Once sufficient time had passed for Onyx’s cock to shrink down to a more manageable size, Cadance shifted her ass to pull the sexual organ free. The knot slid out of her ass with a wet pop, letting Onyx’s latest orgasmic yield drip down the back of her legs to join the puddle of semen already staining the bed; sending yet another shiver of pleasure down the princess’ spine.

Cadance tilted her head back to give the Great Dane one last kiss, Onyx gently brushing his tongue over her lips before the two of them drifted off into a gentle sleep; bodies intertwined in a romantic cuddle that only deepened the bond they now shared.

Things were going to be a lot different for the Crystal Empire’s royal family from here on out, that’s for sure.

*********************

Shining Armor was a bit surprised by the sight he arrived home to after his trip.

The unicorn had been expecting to see Cadance in somewhat a disheveled state,

Instead, what he got was his beloved wife calmly sitting on a sofa in her personal study with none other than Onyx laying beside her, head resting upon the princess’ lap. The alicorn showed no sign of her usual discomfort or displeasure from the dog’s presence and was even gently petting him with one of her hooves while keeping her main focus on the documents levitating before her.

“Honey?” Shining Armor said, causing the princess to lower her documents and smile as soon as she notice him standing a short distance away.

“Oh hi Shining! When did you get back home?” Cadance cheerfully said.

“About an hour ago, had to unpack all the cool collectibles and toys Flurry and I picked up at the convention.” the stallion replied. “But, uh…what’s going on here?”

Cadance tilted her head in confusion. “What do you mean?”

“I mean when I left you didn’t even want to be in the same wing of the castle as Onyx and now you’re

“Oh! Well while you and Flurry were gone, I thought about the way you were always complaining about how I never liked Onyx and decided to spend some time with the big guy; see if we could get along with each other for a change.”

“Really? You did?”

“Yep and we really bonded over the last few days, turns out Onyx wasn’t as bad as I thought. Sure he can be a little rough and overly affectionate but he’s a good dog deep down. Isn’t that right Onyx? You’re a good boy, yes you are!” Cadance said, turning her attention to the Great Dane by her side as she started petting him with even more enthusiasm.

Onyx woofed in response, nuzzling against the alicorn’s hooves and licking her cheek to return the affectionate gesture.

Shining could only smile at the sight. “I knew you’d warm up to him eventually!”

“Alright, alright. I was wrong about him.” Cadance said, gently pushing Onyx away. “Don’t get big headed, Shining.”

“Can I at least have a little ‘I told you so’?” Shining asked.

“Fine. But just one, got it?”

“Got it. I won’t tell you when it’s coming though!” The captain of the royal guard teased. “Anywho, I’m gonna go help Flurry Heart organize all her new toys. We can get you up to speed on what happened over the weekend later tonight.”

Shining Armor trotted up to his wife and gave her a quick peck on the lips, the princess of love reluctantly returning the gesture while keeping an eye on Onyx who had taken on somewhat of an aggressive stance the moment Shining got close.

“See you later Cadance!” Shining exclaimed.

“Bye Shining!” Said Cadance, waving to her husband as he exited the room.

Once he was gone, Cadance looked back down to Onyx who was now bearing his teeth and growling at the empty air where Shining Armor once stood. He clearly wasn’t too happy about the white unicorn acting all affectionate with his bitch, but a pink hoof on top of his head quickly calmed him down and he gazed up at Cadance.

“Now Onyx, don’t be jealous.” The princess of love said.

An annoyed growl came out of the dog.

“Yes, I know. But Shining is still my husband and I told you you’re gonna have to learn to share for now.”

Onyx growled again.

“It was just a kiss on the cheek. I don’t see why you’re making such a big deal out of this.”

Onyx whined.

“Sorry boy, I don’t like it either but I have to keep up appearances for the sake of the Crystal Empire. Which means pretending like I’m still Shining Armor’s loving and devoted wife whenever we’re out in public; but behind closed doors we can still have lots of fun together.”

Onyx whined and sadly nudged Cadance with his head.

“Aw, don’t worry. Shining Armor doesn’t mean anything to me anymore, you’re the one I love Onyx. You handsome little stud.”

Onyx let out a soft woof of happiness.

“That’s more like it, now come here ya big lug.” Cadance cooed, leaning in with puckered lips.

Onyx moved his head up to return the kiss, their respective muzzles meeting in the middle for a soft peck that quickly deepened into something far more lewd with plenty of slobbery tongue action shared between the interspecies lovers.

Their debaucherous makeout session only lasted for a minute or two before Onyx pulled away and rolled over onto his back as if to request a belly rub. But his large red rocket standing straight up in the air made it pretty damn clear what he actually wanted.

Cadance scoffed. “Really? Now? Fine, I really spoil you sometimes.”

Onyx affectionately barked at her.

“Yeah, yeah. I love you too hon.” Cadance said before lowering her head onto the Great Dane’s crotch and giving him a short but sweet blowjob.

Cadance and Onyx would go on to carry out their secret affair for several more years, fucking each other constantly right under Shining Armor’s nose.

They did it everywhere: her bed room, her bathroom, Onyx’s room, the palace observatory, the list simply went on and on. Eventually Cadance started banging the dog in semi-public areas, leading Onyx into a secluded alleyway and letting him plow her right there on the concrete with unaware passerby only a short distance away. Dear Celestia it thrilled her.

Shining Armor never caught on of course, the very idea that his wife would cheat on him was preposterous from where he stood; much less that she’d cheat on him with the family pet. The growing closeness between Onyx and Cadance was somewhat odd, especially when she let him slobber all over her face with a little too much enthusiasm, but Shining thought nothing of it. He merely assumed that the princess of love was simply reciprocating Onyx’s affections…and he was half right.

But then, after three years of interspecies infidelity, Cadance finally decided to bring her relationship out into the open. First by announcing that she was divorcing Shining Armor and then revealing that she had fallen in love with Onyx, detailing how they had carried out their affair in secret and now planned to officially marry the dog so they would no longer have to hide their love.

There was pushback, obviously, especially from Shining Armor who was having a mental breakdown over the fact that the love of his wife was leaving him for a literal animal and Celestia who tried to explain to her niece that she couldn’t marry Onyx because of Equestrian laws against bestiality. But Cadance wouldn’t hear of it, she loved that Great Dane and she was gonna make him her husband one way or another.

Things quickly took a turn when Cadance revealed that she had drafted a new law that would legalize Bestiality in the Crystal Empire, making it so that ponies could date, marry, and have consensual sex with their pets if they do wished. There was a clause forbidding rape, stipulating that trying to manipulate or force animals into having sex with their owners was illegal but nopony paid much attention to that section due to the controversial nature of the act itself.

Surprisingly, Equestria was split on the issue. While there was a sizable crowd who scorned the act with good reason, there was also a significant number of ponies who said it should be passed with some saying it should be enshrined into equestrian law.

Leading the charge on the latter side was Fluttershy of all ponies, the animal lover being Cadance’s strongest supporter and fighting tooth and hoof to help the Alicorn achieve her dreams of true love. At first she was skeptical but after speaking with Onyx for a time, finding out the dog had fallen in love with Cadance from the moment he saw her and was absolutely elated that she finally returned his feelings after all this time but also scared that society would seperate them again, the Pegasus went above and beyond to bring the two together. This of course put her at odds with Twilight who was fiercely fighting against the bill, believing that Onyx had corrupted her sister in law and drove her insane.

This kicked off a long fought court battle, Princess Cadance vs Equestria, where the issue was debated endlessly between the two warring factions. Until finally a verdict was reached.

To summarize the mess of legal litigation that had been spewed out by the court: Cadance won the case and was now free to marry Onyx, with the same being said for any residents of the Crystal Empire who also wanted to marry their pets. Although the act didn’t spread to the rest of Equestria, precedent had been set and if all went well in the frozen north there was a possibility of bestiality becoming legalized across the nation.

Cadance started planning her second wedding immediately after her victory. Making all the arrangements was difficult as most florists and tailors and the like flat out refused to be a part of this ‘abomination of nature’ in their words. But with a bit of determination and stubbornness, Cadance managed to gather up everything she needed for the ceremony. Finding unlikely allies in the form of Rarity (who was now in a relationship with spike, having been spurned into action by Cadance’s boldness to pursue the baby dragon) and Pinkie Pie (who seemed oddly unbothered by the whole mess). Getting the maid of honor was the most difficult as nopony wanted the role, except for Fluttershy who expressed nothing but happiness for the couple and received such duties by default

The wedding wasn’t perfect, Twilight refused to attend in protest and Shining had to be physically restrained after making an attempt to assassinate Onyx, but it didn’t matter to Cadance; she was marrying the dog of her heart, that was enough. Surprisingly, Celestia did make an appearance to officiate the wedding. While the princess of the sun made it clear she still strongly disapproved of the union, Cadance was still her niece and she wasn’t about to stand in the way of her happiness; however taboo it may have been.

After sharing a sloppy but passionate kiss with Onyx on the altar, during which Shining was carted off by a strange mare with an auburn mane, a pale green coat, and a ladybug cutie mark muttering something about getting her love slave back, Cadance headed off to her second honeymoon in Las Pegasus where the two of them were making love to one another nearly non stop; taking advantage of the fact that they no longer had to hide themselves any longer. Things were perfect…almost.

In the midst of their lustful romps, Cadance couldn’t help but think back to the dream that started all of this; where she was starting a family with Onyx. True, she still had Flurry Heart and loved her with all her heart, but Onyx was a good dog who deserved to have some puppies of his own and Cadance decided to make that dream a reality. Performing research on how to make their reproductive systems more compatible, it hasn’t yielded any solid results yet but Cadance has been making great progress thus far. Love can motivate ponies to overcome any obstacle after all.

Upon returning to the Crystal Empire, the new royal couple received a somewhat frigid welcome. Most ponies weren’t exactly comfortable that a dog was the new prince, having replaced Shining Armor who was relatively well liked by the populace (who had also been missing since Cadance and Onyx’s wedding, apparently kidnapped by some unknown party). But Cadance pleaded with the populace to at least give her new husband a chance, saying much of the same to her daughter Flurry Heart who was struggling somewhat after her parent’s divorce and refused to accept her new step-dog.

So they did and as it turns out, Onyx was a pretty damn good leader once you got past the language barrier; luckily Cadance had long since learned to speak dog and could translate his woofs and barks just fine. Countless improvements were made such as larger parks with plenty of room to frolic in and increased funding for animal shelters and schools, among other positive acts. In two months time, Prince Onyx’s approval rating was nearly double that of Shining Armor’s amongst the citizens of the Crystal Empire and they quickly recognized the Great Dane as their new ruler.

Flurry Heart was slower to warm up to him, which was understandable since Onyx had basically forced her biological father out of her life. But after a bit of innocent doggy daughter bonding coupled with a few comforting talks from Cadance, the young alicorn got over her reservations at having a dog for a dad and accepted Onyx’s role in her life as a parental figure.

Life went on from there, Cadance and Onyx maintaining a healthy sex life well into their relationship while performing their royal duties flawlessly. Of course the difference in life spans meant that Cadance would one day outlive her canine husband but she quickly resolved that matter by granting him immortality and ensuring the two of them would never be separated.

The memories of her former love faded, Shining Armor’s disappearance was never resolved (although rumors of albino changelings appearing in the badlands started to surface), and even her aunts learned to love their new dog-in-law after a while.

When all was said and done, Cadance had gotten over her dislike of canines and now proudly considered herself to be a dog lover. That weekend with Onyx had been the greatest thing to ever happen for both of them.

Author's Note

FINALLY! IT'S FINALLY DONE!

Phew, didn't think this would end up being 11K words but it's fitting considering this is the grand finale to Cadance's foray into the world of dog fucking.

Hope you all liked the conclusion to this devious little work. Now I'm gonna go return to the smut pits for another year of hibernation, emerging only to post more pornographic stories.

Thanks for reading!
