The sun shined brightly through the glass windows into the dining room of the Crystal Palace.
At the table Shining Armor and Princess Cadance sat eating their breakfast, their daughter Flurry Heart in her high chair besides them.
Having meals together was their favorite part of each day, since their schedules often kept them busy and apart except for when it was time for bed.
The Prince and Princess talked about their usual things, mainly their schedules and future plans for the next week and month, when a servant pony entered the room, carrying a box on his back.
“Your majesties, this package just arrived for you from Princess Twilight.” Said the butler as he used his magic to levitate the box onto the table besides them.
“Thank you sir.” Said Cadance to the butler who bowed in reply and left to carry on with his work.
“What is it honey?” Asked Shining Armor as Cadance began to open the box.
Before she could get more than a glance at the item however Flurry Heart flew out of her high chair and grabbed the box, flying around the dining room with it in her hooves.
“Flurry Heart! Come back here!” Yelled Cadance in a worried tone.
Both parents left their seats and began chasing after their daughter.
Cadance flew after her while Shining tried to stay below her, ready to catch the foal if she fell.
Eventually the weight of the box seemed to become too much for the young foal, who let go of the box before starting to fall to floor herself, tired from her hyper flying.
Shining and Cadance immediately sprang into action, with Shining catching the box and Cadance catching Flurry Heart.
However, that was the graceful way of putting it.
When Flurry dropped the already opened box the item and packing materials began falling everywhere to give way to a clear glass sphere.
Shining immediately ran forward and jumped up, catching the sphere in his hooves.
At the same time Cadance had surged forward in the air catching Flurry in her arms and holding her close. She was so preoccupied at rescuing Flurry that she didn’t notice how close she was to the room’s chandelier, clipping it with her wings and losing control before falling to the floor herself and landing right into Shining Armor in a pile of tangled limbs.
Had they taken much notice, they would’ve noticed that each of their limbs were touching the sphere, which began to glow the colors of their coats before returning to it’s clear and translucent color.
The couple slowly got to their hooves, rubbing the sore parts of their bodies and setting Flurry Heart back in her high chair as they composed themselves.
This was not an atypical occurrence in their daily lives since Flurry had been born.
She always seemed to get into some kind of mischief now and again.
But no matter how many things she broke or how many sore muscles she caused, they would never stop loving her.
She symbolized their love for each other, the future of Equestria, and their commitment and responsibility as two halves of the element of love.
After this bit of morning chaos however, the two now needed to get a move on. Their morning meetings were starting soon.
They both quickly finished breakfast and gave Flurry a kiss goodbye as they gave her to her nanny for the day and went their separate ways.
The Nanny took Flurry and the sphere, which had been placed back in the box by Shining in a hurry and headed toward the Royal families living quarters.
Cadance and Shining decided they would look into the package Twilight had sent in the evening when they had finished their work for the day.
Little had they realized the importance of an envelope that was in the package that had so needed their attention.
Shining Amor headed towards the guard quarters of the castle.
Like every day after breakfast his morning would start by leading the Crystal Guard in morning warm-ups before heading into more intense exercise.
It was a ritual he took pride in, always remembering the importance of it when he was a young cadet in Celestia’s Royal Guard.
He was proud of every stallion and mare under his command and knew they were some of the best knights all of Equestria had to offer.
As he walked, he failed to notice changes starting to affect his body.
His muscles, which rippled under his white coat began to slim down, losing their bulge and becoming more petite like an average pony.
His mane and tail also changed slightly.
Both became slightly longer and thinner, looking more effeminate like a mares.
As he made his way to the outside of the castle grounds, he found the ponies under his command chatting on the training course while they waited for him.
“Alright troops! Fall in line!” Yelled Shining Armor.
The ponies turned to face their leader, but were puzzled when they saw him.
The buff and handsome stallion they were used to now looked more like a civilian colt with his somewhat slim body, and his mane and tail made him look like whoever cut it was intending to cut a mare’s hair, not a prince’s.
Shining Armor would have no odd looks on his watch however.
“Do you have fluff in your ears soldiers? I said fall in line!” Yelled Shining Armor again as the troops nervously obeyed his commands.
Maybe their eyes were playing tricks on them. It was still early after all.
Shining Armor quickly started the troops on their morning exercises, walking the yard and giving feedback to those who needed it.
As he did so, more changes began to occur.
His butt, which had slimmed down a bit when he became more slender, now was ballooning outwards.
His butt went from flat to curvy and plump in mere moments, his thighs and hips gaining some curvature as well, giving him a figure that now looked more like a mare’s then any stallion’s.
His thoughts also seemed to be changing.
When he usually oversaw training he would occasionally sneak a glance at a few of the mare’s plots as they exercised.
He was just like any other stallion and enjoyed the view of a nice butt like any other male.
But this time he found his eyes drifting toward the stallions.
His mind began to wander about how big of a package they were hiding underneath their training uniforms and how nice it would taste to wrap his muzzle around their thick and juicy…wait.
Shining Armor shook his head, trying to organize his thoughts.
Why was he looking at stallions like that?
He never had thoughts about males like that before.
He tried to look at the mares again and how their butts would jiggle when they would move.
That always got him hot and steamy under his coat.
But no matter how many times he tried he found his eyes lazily wandering back to in between different stallions legs, his thoughts wandering to all the things he wanted to do to make each stallion cum.
He knew something wasn’t right.
“Keep training everyone! I’ve got something that needs my attention. Commander Spearhead, you lead the soldiers in their drills until I get back.” Said Shining Armor.
“Yes sir!” Said Commander Spearhead, taking Shining Armor’s place at making the rounds.
Shining Armor couldn’t help thinking how hot Spearhead looked as he took charge of the soldiers.
His thoughts were filled with naughty ideas of the Commander dominating him as he made his way to his office just off the training field and closed the door behind him.
Sweat dripped down his body as he got himself a glass of water and began trying to calm himself down.
What had gotten into him? He never had thoughts like these before.
Sure plenty of stallions and mares liked the same sex as they were or even both, but he had never felt that way. And why now were the mares not doing it for him at all?
He locked the door to his office and opened a locked drawer at his desk, pulling out a magazine.
Inside were a bunch of images of mares posing sexually in lingerie and pleasuring themselves.
If anything was going to get Shining thinking right again, it was these lovely pieces of flank.
He immediately began to flip through the pages with one hoof while reaching down between his legs with his other and stroking his emerging cock.
His mighty tool was beloved by his wife for its somewhat generous shape and size. It was bigger than most, but not too much to handle.
As he looked at the provocative mares and began stroking himself though, his thoughts began to wander elsewhere.
Every mare he looked at he began to think less of what he would want to do to them and began to think more of him in their place.
He pictured himself wearing a skimpy pair of panties that showed off his big ass, he pictured himself running his tongue over the length of a big stallion cock, and lastly and most strangely, he thought of spreading the lips of his pussy invitingly for a stallion to enter him.
As he stroked himself, his cock began to shrink, with his balls following suit.
Soon he was at average size, then small, then almost nonexistent.
As he neared release and came, his cock and balls vanished entirely giving way to an inviting vagina that gushed cum as the now female guard thought of herself being ravished by a stallion as a nice pair of crotch boobs bloomed just above her quivering flower.
They were generously sized, perfect for a stallion to play with and get her warmed up.
Lastly, the former stallions mind began to shift.
Gone were all the memories he had of being a stallion.
Memories of working out were replaced with putting on make-up, game nights were replaced with going to the mall with her marefriends shopping, her memories of all the dates she had with Cadance and their life together changed to her being with a buff and pink alicorn stallion who she loved making love to more than anything.
She remembered all the loving memories they had together, their marriage, and how she had bore him a foal.
Everything else fell into place.
She was Gleaming Shield, Princess of the Crystal Empire by marriage. She was the wife of Prince Crescendo, and Mother to Prince Blizzard Heart.
She was best friends with her sister, Princess Twilight Sparkle and the elements of Harmony. She was Captain of the Royal Guard in Canterlot before getting married and now leading the guard from the Crystal Empire.
She was one of the toughest mares in Equestria and she was proud of it.
As the changes finished, the former stallions face changed slightly, with her muzzle becoming petite and slender and her eyes were accented in mascara to give them a look that while caring and passionate, also burned with determination and courage.
The new Princess caught her breath as she reviled in her climax.
Sometimes the ripped stallions really got her fire going. Especially when she was in heat.
She went to her private attached bathroom and washed her hoof.
The office that had belonged to Shining Armor had changed slightly.
All the awards and documents that had Shining Armor’s name on them had changed to Gleaming Shield, her family portrait had changed from a picture of a wife and daughter to a picture of a husband and son, and the magazine of naked mares her former self had been looking at had changed to pictures of sexy clad and naked stallions showing off their muscled bodies and thick cocks that begged to be taken care of by caring mares.
Gleaming Shield went over to her desk and placed the magazine back in her drawer, closing and locking it before walking back outside to address her soldiers.
Now that her arousal had been dealt with she could resume command.
If her soldiers had remembered that their mare Captain had once been a stallion they would have noticed that Gleaming now walked with a saunter in her step that only a mare learned from watching other mares from a young age, knowing full well that it made all the stallions look at them the way they liked.
Sure enough she could see some of the stallions looking at her as she approached, seeming some of them becoming shy and their training shorts tenting up a bit.
She didn’t mind however. She knew they couldn’t help it. It was flattering in a way to know that even though she was a Mom now that stallions still found her so beautifully sexy.
If it wasn’t for her dedication to her Prince she might even take one of these stallions on a date with a happy ending. But those days were behind her. She had troops to command and they knew to put their primal desires aside in the name of their service to her, her family, and the empire.
“Alright troops! It looks like Commander Spearhead has warmed you all up enough. Let’s start today with four laps around the track. Let’s move those hooves!” She yelled with authority.
“Yes Ma’am!” The soldiers responded, galloping over to the track and beginning their laps.
Gleaming followed behind them. She knew today was going to be a good day.
Princess Cadance strolled through the castle halls toward the throne room.
This morning she had a meeting scheduled with local business owners to help plan the next Crystal Fair in a few months.
Even though she hadn’t lived in the empire for too long, she found the festival to be a fun and important tradition.
She couldn’t wait to take Flurry to her first one!
As she walked, she failed to notice changes taking place.
Her petite figure, which had curves in all the right places, began to balloon outward, losing its feminine appearance in favor of muscles that vaguely showed through her coat.
Her mane and tail also changed slightly.
Both became slightly shorter and bushier, looking more masculine like a stallion’s.
Soon she entered the throne room and made her way to her throne, placing her now larger and rock hard butt and resting it on the soft cushions of her throne.
“Please let the business owners in now.” She commanded the guard standing by the door.
The guard did as he was told and opened the door.
He thought that something about the Princess looked different today, but the distance between the two of them was far enough that he could not really tell what it was, and he knew better then to bother the Princess with his thoughts.
The business ponies made their way into the throne room and stood at the foot of the throne before Cadance made her way down the stairs to greet them.
As she walked toward them, the shop ponies couldn’t help but stare puzzled at their Princess before them.
The beautiful and elegant Princess they knew now looked like she had been hitting the gym. Her muscular barrel and limbs looking so foreign on the elegant mare.
They knew better than to say anything however.
They were here to ask her approval for their stand plans at the Crystal Fair, and although Princess Cadance was not one to be offended easily, they didn’t want to risk it by commenting on her tough physique.
“Thank you all for coming. It’s so nice to see you all again. Please, join me in the meeting room so we can be comfortable while we work.” Said Cadance, whose voice seemed to be getting a bit deeper.
As Cadance took her seat at the table she couldn’t help but notice the mare taking a seat next to her.
Her name was Fashion Forward, an owner of one of the biggest boutiques in the empire, and had been the official supplier for many of the pieces of clothing that were sold at the fair each year.
She had always been generous in her service to the fair, choosing to donate most of the bits earned to the empire rather than herself.
Cadance had always admired that about her.
Right now what was catching her attention about the mare was how beautiful she looked, her mane and tail beautifully curled in such a way that it made the mare look like a work of art. Her green eyes shown like emeralds as they looked back at her and her body being one any mare would be grateful to have with curves in all the right places.
“Princess?” Fashion said to her.
Cadance snapped out of her trance.
“Y-Yes Fashion?” She asked.
“We were wondering if it was ok to start now?” She asked respectfully.
“Oh yes right sorry. I thought it would be a good idea for everypony to talk about what they would each specifically like to do and once you’ve all gone we can each give feedback on what we feel could improve things for each one of us.” Said Cadance.
The sales ponies nodded in agreement and Popped Kernel, the owner of a popular snack shop in the empire spoke first.
As each pony went around the room Cadance found it hard to focus on what was being said, her eyes kept drifting back to Fashion.
She thought of how sexy Fashion would look in some blue lingerie to go with her pinkish white coat and light purple mane and tail.
She pictured Fashion posing seductively in front of her, asking her to remove her panties with her teeth so that she could gain access to her warm and tight…no.
Cadance shook her head trying to clear her foggy mind.
What was she saying?
She had never thought of mares in such a way before.
She tried thinking about Shining Armor and her favorite moments of him pleasing her.
But no matter how much she tried to picture Shining and his dick, all her mind could seem to think about was Fashion and how inviting her pussy must be.
She knew she needed to do something.
“Excuse me a minute everypony. I just need to freshen up.” Cadance said as she made her way to the hall and then to the nearest bathroom, locking the door behind her.
Why was she thinking about mares all of a sudden? She had always loved stallions!
Her love for Shining Armor was something she never questioned. He was her everything and that would never change.
She took a seat on the closed toilet and began to think.
She thought that maybe she was just having a rough morning.
The breakfast incident with Flurry Heart was certainly not a great start to the day.
Maybe she just needed some release so she could concentrate again.
She reached her hoof down and began to rub her pussy, her lips parting to accept the edge of her hoof as it stimulated her most sacred area.
She tried to think about holding Shining Armor in her arms as he thrusted in and out of her, but her imagination quickly changed from Shining Armor bucking her, to her bucking Fashion.
She thought of how Fashion would moan as she thrusted her cock into her and clenched around her tool, only fueling her thrusts more.
As Cadance rubbed herself, she failed to notice her clit starting to push out, becoming thicker and longer as she transitioned from rubbing her clit to stroking her new impressive cock.
The lips of her vagina soon vanished as they puffed out into an impressive ball sack that hung just below his taint.
Cadance didn’t even take notice of the new appendage, simply wanting to fulfill the urges his new stallion body was feeling.
Her crotch had been a slightly darker shade of pink that matched her coat, but now turned a dark leathery black.
Cadance continued to stroke himself furiously until finally he sent himself over the edge and came, spewing warm and sticky cum all over his tummy.
As his cum made contact with his last mare appendage, his breasts, they receded into his body, becoming flat.
His fetlocks became unshorn, typical of a stallion his size.
His face, which had been perhaps one of his most beautiful features, surged outward as his head became stockier and his muzzle began more pronounced.
Finally, all his new thoughts rested into place.
Gone were all the memories he had of being a mare.
Memories of putting on make-up were replaced with working out, going to the mall with her marefriends shopping were replaced with game nights, her memories of all the dates she had with Shining Armor and their life together changed to her being with a sexy and white unicorn mare who he loved to cuddle and buck every night.
She remembered all the loving memories they had together, their marriage, and their foal.
He was Crescendo, Prince of the Crystal Empire. He was the husband of Princess Gleaming Shield, and Father to Prince Blizzard Heart.
He was Princess Cadance’s nephew, and had been raised by her and Princess Celestia to lead the Crystal Empire and be the element of love with his wife.
He ruled over his empire fairly and with care, which he took pride in.
The new Prince caught his breath as he reviled in his climax.
It was hard sometimes to not act on the urges he had when he saw a pretty mare.
Sometimes a stallion just has to rub one out.
He grabbed a towel and wet it with hot water, cleaning his cum from his coat before rinsing the towel and storing it in the bathroom closet in a hamper to be laundered and putting a new towel on the rack.
He then exited the bathroom and made his way back toward the meeting room.
It had been a good thing that whatever magic was at worked had also stretched the former Princess’s regalia to fit the new chiseled stallion’s body.
He was soon back in the meeting room and making his way back to his seat.
Had any of the ponies remembered that the prince was once a Princess, they probably would’ve been surprised to find the stallion strolling in, leading his body with his chest rather than with the strut her mare self had that had attracted the eyes of Shining Armor the first time they meet.
As far as the shop ponies knew they had known Prince Crescendo and his wife for years.
Crescendo took his seat at the table and began to listen intently to the discussion and take notes like he had before his little “bathroom break”.
He couldn’t wait for the day to be done so he could see his loving family.
Baby Flurry Heart babbled to herself as her nanny carried her to her families living quarters.
Her Nanny, Playtime, had been so honored when she was chosen as Flurry’s new caregiver after Sunburst had moved to Ponyville to work at Princess Twilight’s School of Friendship.
She took pride in caring for her young charge, treating her as she would her own foal.
Soon they were back in the Royal Family’s living quarters where she placed the package on their kitchen table and then brought Flurry into her nursery so the young foal could play.
Playtime took a seat in a rocking chair and grabbed a book she kept there, reading it while she kept an eye on the baby pony.
A couple hours later, Playtime decided it was time to check Flurry’s diaper.
A quick check of her diaper revealed that Flurry Heart was in need of a change, so Playtime picked her up and brought her over to the changing table.
As Playtime began to gather the diaper supplies, Flurry began to feel a bit funny.
The little foal did not have many memories being only a little over a year old, but what little memories she had began to change.
Memories of her Mommy being pink and having wings and a horn changed to her Mommy being white and having just a horn.
She now remembered her Daddy having wings and a horn and being a royal instead of a unicorn guard pony.
All the times her parents called her their beautiful baby girl became them calling her their handsome baby boy.
If Flurry had been older she likely would’ve asked her Nanny for help, said that something felt wrong and to get her parents, but the little foal just made her usual cooing and babbling noises as she felt her mind tingle slightly as it changed.
The little foal’s body changed ever slightly.
Her mane and tail shorten slightly, going from a baby filly’s length to a baby colt’s length.
The only other change she experienced, while the biggest change, hid itself from anypony’s eyes beneath her diaper, as the part that made her a princes puffed out and into the shape of the part that now made her a prince.
As far as anypony now knew, Flurry Heart had never existed.
As of yet the Crystal Family only had one child, a colt named Blizzard Heart.
He was the future heir to the throne and the son of Gleaming Shield and Crescendo.
The room that Blizzard and Playtime were in was the last thing to change.
Although Flurry’s room had been designed to accommodate whichever gender foal the royal family was going to have, a few things that had been added after Flurry’s birth began to change.
The armoire which held lots of cute dresses and baby cloths geared toward filly’s changed to hold the cloths of a baby colt, and the baby toys that had been scattered around the floor changed from their more girly colors to colors a boy would typically like.
As Playtime finished gathering the supplies for the now Prince’s diaper change, nothing about Flurry Heart now being a boy alarmed her.
As far as she remembered, she was always the caretaker to a young Prince.
She quickly set to work, unclipping the cloth diaper and setting it in a sealed bin to be washed before carefully cleaning the Prince’s diaper area and then lifting Blizzard up by his legs with her magic sliding the new diaper underneath, making sure to put plenty of powder on the little colt’s bum and crotch so he wouldn’t get a diaper rash before closing and pining the diaper back into place.
She then set the young colt back on the floor to continue his playtime and went back to her book.
As far as both ponies knew, this was just a normal day.
Prince Crescendo walked with his wife toward their living quarters, his right forehoof wrapped around her neck in a light embrace.
The two had finished their royal duties for the day and were looking forward to spending the night together with their son.
The two passed the time by telling stories about their day and exchanging the occasional kiss or knuzzle that only two ponies that are madly in love understand.
Soon they reached the door to their live in quarters and walked inside, finding Playtime waiting for them with Blizzard Heart held in her arms. She was used to the Royal couples schedule and had been waiting for them.
“Playtime! How was our little colt today?” Asked Crescendo, taking his son from her hooves and giving him a hug.
“Very good your highness. No tantrums today.” Said Playtime as Crescendo and Gleaming walked her to the door.
“That’s my good little soldier.” Said Gleaming, giving him a kiss on the cheek.
“Thank you as always for looking after our little angel.” Said Crescendo.
“Oh it’s my pleasure your highness. I’ll see you all tomorrow.” She said, bowing before making her way down the castle hall to her own quarters.
The rest of the night went routine for the royal family.
Both Crescendo and Gleaming bathed together to save time and because they enjoyed each other’s company.
Gleaming them breast feed Blizzard his dinner before they all made their way to the royal dining room so that she and Crescendo could eat.
They then retired to their room for the night and laid Blizzard Heart down to bed before going to bed themselves.
The couple did not have sleep immediately on their mind however as Gleaming flicked her tail in Crescendo’s face as their entered their bedroom.
“You’re such a tease Captain. You best be careful though, I’m good at outwitting defenses.” Said Crescendo as he maneuvered his way around his wife and pressed his lips passionately against hers, bringing her into a tight embrace.
Gleaming kissed him back, their tongues dancing inside each of their mouths before they broke their kiss for air.
“It appears I’ve meet my match. Please be gentle.” She said, smiling mischievously at Crescendo who smiled back just as coyly.
“Of course my Princess.” Said Crescendo as he laid his wife down on the bed.
Their foreplay had gotten both of them heated up, with Gleaming’s pussy beginning to become wet in anticipation of Crescendo’s member, which was sticking out prominently between his legs.
He lined himself up with her entrance before penetrating the unicorn’s lower lips.
They both moaned in pleasure as Crescendo continued to push his cock inside his wife until his large balls made contact with her ass.
He stopped for a moment to take in the feeling of his wife’s inner walls wrapping his cock in a warm and tight embrace.
This moment did not last long though, as Gleaming moaned below him loudly.
“Please buck me! I need you!” She urged him.
Crescendo responded, pulling out until he was barely inside her then going back in, gradually increasing his pace as he went until he was pounding his sweet wife’s ass like a jack hammer, eliciting moans and gasps from each of them at the pleasure they were giving each other.
At the same time this was happening, Blizzard Heart stirred in his crib.
The little colt could not sleep, especially with the noise he was hearing in the next room.
Using his magic, he poofed himself into the main living area that contained the kitchen and living room.
His eyes immediately fell to the box on the kitchen table, picking it up and flying throughout the place like a wonderbolt in an air show.
He soon flew into his parent’s room, the couple forgetting to close the door in their eagerness to mate.
The couple did not notice Blizzard flying above them; both concentrating on the sexual feelings their son was still many years off from understanding.
Blizzard heart saw his Mommy and Daddy doing something on the bed below him.
It looked like they were playing together.
He wanted to play too!
He let go of the box and flew down towards his parents.
As he let go of the box, the strange sphere that was inside fell out of the box and started falling towards the floor, straight toward Crescendo and Gleaming Shield.
Both ponies were now close to orgasm as Crescendo bucked his hips at a break neck pace.
Just as he winded up and plunged his cock deep into Gleaming’s pussy and came, a glass ball landed in between the two lovers, landing just above their crotch areas.
Blizzard Heart was not far behind it, flying into a landing right where the ball had and his face making contact with it.
Before anypony could react, a magical surge burst forward from the alicorn foal’s horn, activating the sphere and enveloping all there ponies in a magical aurora.
In a matter of moments, both alicorn’s cocks began to recede into their bodies. Their old set of pussy lips returning where they had that morning.
Their shorter manes and tails became longer and elegantly styled, and Crescendo’s buff body shortened slightly in height and became slim and curvy, returning both ponies to their former Cadance and Flurry Heart selves.
Gleaming Shield’s body burst forward in more ways than one, with muscle bursting forward from her thin and curvy frame into a well built stallion’s body and his cock that he possessed that morning bursting forward from the pussy that just minutes ago had been flooded with alicorn semen.
His mane and tail shortened slightly and returned to the style of that of a stallion, returning him to his old Shining Armor self.
The three ponies collapsed exhausted on the bed, the strong magic taking a serious toll on all three of their bodies as they passed out fast asleep.
The sphere rolled off the bed and against the base board of the wall on the floor to be dealt with in the morning, this time luckily right by Twilight’s note on what it did and what to do with it.
As far as the royal family knew, none of what happened that day had taken place, their old memories returning when the magical effects of the artifact had been reversed.
As far as they remembered they had lived the day as their normal selves, all traces of the sphere’s magic having disappeared.
Except for one.
Had anypony been conscious to observe the sleeping family they might have noticed one key detail.
A white, creamy liquid covered Shining Armor’s butt cheeks and ball sack just below his taint.
And as anypony knew from reading this story, sometimes a small detail can make all the difference.
