Luna’s moon shined down on the silent night, as its light fell over the Crystal Empire. Shining Armor and Cadence were playing with their foal Flurry Heart, as she crawled towards her parents from across the room. Cadence was encouraging her by cooing, “Come on Flurry, you can do it.”
And Shining was shouting encouragingly, “Come to Daddy, come on.”
This made Flurry giggle and babble, as she crawled towards her mother. Shining hugged his wife, watching his daughter fall into her mother’s forelegs, then they both congratulated her with kisses and hugs. Cadence then placed her on the bed to be changed as Shining asked, “So we doing anything for your birthday tomorrow?”
Cadence looked back at her husband and smiled, “Yes we will, Shining. I’ve got the whole day planned. “
Shining eyed his wife as he asked, “You still haven't told me what you got planned. Just what are we going to do?”
Cadence’s smile grew wider as she stifled a laugh, “Oh Shiny, if I told you it would spoil the surprise.”She then picked up Flurry and began to set her in her crib.
Shining took ahold of his wife and nuzzled her ear then said, “Come on, just tell me. I can act like I’m surprised.”
But Cadence only replied, “If I told you, I doubt little Shiny will come out to play.”
This made Shining give Cadenced bedroom eyes as he scoffed, “Alright, looks like I'll have to work to find the answer.”
Cadence gave him a sly smile, “Yes you will, now lie in bed like a good little colt.” Her husband then trotted off to bed, as Cadence finished tucking their daughter in.
Cadence was the first to wake in the morning only to be staring at what seemed to appear as a mobile. A sun hovered above her head with wooden objects painted in primary colors of pink and blue. She yawned only to feel a rubbery object in her mouth. She suckled for a second not understanding what was going on. She tried to rise but only managed to fall back on a pillow. She kicked her back legs and felt something between them, something soft and making crinkling noises. She looked down at her blanket and her eyes grew wide in utter amazement. It was pink and little rattles and teddy bears decorated the outer cover.
Then she heard snoring and turned her head to see her husband and the pacifier that was in her mouth fell out. He was underneath a blue foal blanket and was sucking a pacifier rhythmically. Cadence rolled under the sheets and nudged her husband. He whimpered a bit so she shouted “Ge up Shiny!”
Shining groggily opened his eyes and replied back “Whas wong?” Then he gasped at his voice, and got up looking around frantically! Cadence in turn looked around and she realized they were in a oversized crib! Shining, shaking all over, took the blanket and lifted it up! Cadence held her hooves to her mouth as she stifled her giggles. Around her husband’s rump was a light pink diaper with little purple hearts covering the outer fabric. What was worse was the fact that it was now stained yellow and sagging around his crotch. Shining's eyes grew wet with tears as he began to bawl.
Then they heard “Awww, are Cady and Shiny waking up?” They both turned their heads to see Twilight coming towards them with a huge smile on her face. Her horn glowed and both were helplessly carried out of the crib. Shining was the first to shout “Twily! Wha di ya do!?”
Twilight giggled at her brother's lisp and asked with a hint of a teasing, “Oh, Cady didn't tell you what she had planned?”
Cadence and Shining were both placed on the biggest changing table ever constructed as Shining turned to his wife and angrily shouted, “Ya pwaned this!”
Cadence laughed out loud as her legs were spread open, “Yep! Today, we gonna be foals! I knew you’d wefuse if I told you.”
Shining spread his legs open and saw that Twilight’s horn was still glowing. “Twily, wha ya doin?” he asked.
Twilight gave her brother a motherly smile, “Come on, Shiny, I can't have you spend the day with Flurry Heart in a wet diapee.” She untaped both Cadence and Shining’s diapers, then wipes were lifted with the same power, and they started to have their bottoms and crotches wiped down.
Shining blushed and shivered as he felt the cold wipes touch his body. Twilight cooed, “Hold still, sweetie.”
Shining turned his head to see Cadence smiling as she had her crotch wiped down. Then he yelped as he felt the cold foal cream hit his bottom. Twilight burst out laughing and cooed, “Come on, Shiny, it's just foal cream.”
Shining glared at his sister, “Whaeva, ya stiw didn tell us wha ya did!”
Twilight replied, “Well I researched some simple mind spells and regressed your mind to that of a two year old, you still can talk and trot around but I need to make sure you and Cady play nicely with little Flurry. Don’t worry, it’s only for the day, then I promise you’ll go back to normal” She applied the foal powder to their rumps and started to rub it in. Then she placed two new diapers around their rumps and taped them around their crotches. “Alright, give me a few kicks so I know they fit.” she instructed.
Both Cadence and Shining kicked in their new diapers, letting clouds of foal powder puff around them. Then Shining coughed as the foal powder hit his nose. Cadence just giggled “Twily, ya good at this!”
Twilight bowed, “Thank you, I've been preparing like you told me.”
Shining wanted to say something himself, but the two were whisked away once again in Twilight's telekinesis and carried off.
Soon, they were settled in two high chairs in the back of their bedroom and sitting in the middle was Flurry giggling happily and bouncing in her chair. Shining looked around and noticed that his room was now basically a adult sized nursery, with a changing table near the side of the room, and adult sized cribs near the back. Shining sat in his high chair as Twilight came in with a spoonful of foal food and smiled as she said “Come on, Shiny, open wide.”
Shining reluctantly opened his mouth as Twilight levitated the blue rubber spoon with foal food piled on top of it. He didn't want to go near the foal food but he opened his mouth and let it enter anyway, he was starving. He swallowed the mush as twilight giggled, “Oh Shiny, you got it all over your face.”
Shining pouted and shook his head, “Na uh.”
Twilight grabbed a rag and wiped the foal food from Shining’s muzzle as she giggled and asked, “Then what's all this?”
Shining blushed seeing that the rag was stained with foal food. “Ya di somthin to my mouth.” He babbled, though he knew that wasn’t true.
Twilight laughed as she fed Cadence foal food. Then, when she had finished feeding the two and Flurry Heart, she went to Flurry and cooed, “Alright, time to play with your Mama and Dada.” Flurry squealed in excitement.
Shining smiled seeing his daughter super excited like that, maybe playing with her wouldn’t be so bad.. Then he turned to see Cadence being lifted from her highchair and placed in the playpen with her daughter. Cadence bounced in her diaper as Shining tried to get out of his highchair by himself but found it very difficult to move the tray. He grunted as he tried lifting it and failed. Then he looked at his sister with tears forming in his eyes. She came over and hugged her B.B.B.F.F and whispered, “It's okay, Shiny, you don't have to worry about lifting that.”She then lifted the tray from his belly and helped him into the playpen.
She then hovered over the two and whispered, “Alright you two, I'll be watching from here. Now go on and play.”
Shining crawled over to Flurry Heart, and she giggled as she flew into his hooves and landed on his diaper. He smiled and snuggled Flurry with his muzzle, then she laughed in turn and rolled around in his lap giggling and cooing. He smiled at her and cuddled her in his hooves making her laugh and squeal. Shining looked up and asked, “Cady why didn ya tell me this was ya had in mind?”
Cadence blushed, “Well I didn't think you would agwee. I sowie fow keepin this a secwet.”
Shining replied, “I gwess ya wight, I pwoabalow would of said no. I guess one day in diapees won be so bad as wong as is just you, me, and Fwurry.”
Cadence smiled as Flurry went from her dad to her mom babbling and cooing along the way. Cadence picked up her daughter and smothered her in her embrace. Then she nuzzled her daughter and asked “Wana pway with bwocks?”
Shining looked at the blocks with curiosity and replied, “Ya, wets pway.”
Cadence nodded and then she and Shining, along with Flurry, crawled over to a group of giant foam blocks and started to stack them on top of each other. Shining laughed as Flurry took a block and began to suckle on it, prompting Cadence to reply, ”No Fwuwwy, ya gotta bwild with it, not suck on it.”
Shining looking at the foam block in his hooves and began to suck on it. Cadence sighed and then took a block and began to suckle on one too.
. Twilight dawwed and replied, “Oh, that's adorable. Now, I need to know what will you be doing for the talent show I have set up?”
Shining dropped his block as he looked up at Twilight and shouted, “Wait, what?!”
Twilight laughed, “Oh Shiny, I forgot about the little birthday party for you and Cady today. I was thinking you can show the kingdom how talented you all are.”
Cadence giggled as she tried standing up amd shouted, “I vewy tawenetd, I wana dance fow the ponies.” Then she fell on her padded rump as Twilight cooed, “That was cute, Cady.”
Flurry got excited and crawled over to Twilight, babbling and cooing, making Twilight giggle, “Alright, it looks like Shiny needs an act now.”
Shiny crossed his forelegs in response and put his head up. “I not goin in pubwic in a diapee!” he protested.
Twilight rolled her eyes then said, “Fine, Shiny, you dont need to have a talent. But you're still going out to see your subjects. They came all this way just to see you. It’ll only be for a little while.”
Then Shining, Cadence and Flurry were teleported in a foal buggy. Then Twilight placed pink foal bonnets around Cadence’s and Shining’s heads, and then stuffed animals were given to each pony. Twilight whispered, “Alright, time to go show the world how cute you all look.”
Shining covered his eyes, he couldn't believe what was happening when he opened them. He saw himself staring at a crowd of ponies that had gathered in the crystal palace’s throne room. This was enough to have him shaking all over. Then he, Cadence and Flurry were taken out of their buggy and placed before the ponies. “Here are the three royal foals.” Twilight declared.
The crowd stood in place as Shining tried to placed his hooves over his diaper but this only made the crowd dawww even more. Cady then bounced in the air in her diaper and tried dancing but she kept plopping on her behind making the ponies squeal each time. Then Flurry squealed in glee as she crawled towards the crowd babbling and making all the ponies daww once again. Shining then heard a hissing sound and felt something warm and wet grow between his legs. Twilight gasped as she saw her big brother cross his legs trying to stop the flow! He then looks at the crowd in tears and started to wail! Twilight rushed over and cuddled him, as his head hugged close to her chest.
“Hush now, it's okay.” Twilight told her brother.
The crowd was silent as Shining raised his head and babbled, “Twily, I wana go back to the nusewy.”
Twilight whispered, “Sure we can sweetie. But Cady will be very sad, and it’s her birthday.”
Shining looked at his wife and daughter now amongst the crowd and playing with the adult ponies, they looked like they were having fun. Who was he to deny them that fun? Besides, hadn’t he longed for a chance to be free from the pressures of his job, just for one day?
Shining tried crossing his back legs, scrunching his diaper and looking back at his sister with tears glistening in his eyes. “I wet my diapee though.” he said sadly.
Twilight brushed his mane, as she reached with her front left hoof and scrunched his diaper. She then cooed, “It's only a little wet, you think you can hold off for a few more minutes?”
Shining shook his head with a expression of disappointment and muttered, “I don wana. The bi ponies awe gonna waf at me.”
Twilight replied, “I promise nopony will laugh at you. Everypony here knows this all for fun and you won't be laughed at.”
Shining wiped the tears from his eyes and babbled, “Ya pwomice?”
Twilight kissed him on the forehead, “I promise, now go out there and be with your family.”
Shining gave Twilight a nervous smile as he turned to the crowd of ponies clapping at Flurry and Cadence, who were playing and prancing around the citizens. Then Shining shouted, “I got a tawent to!” Everypony looked up as he scrunched his face, turnining it beat red. He then fired his horn, creating a little magical shield that appeared around him, then it fizzled out. The ponies all clapped and cheered!
Cadence strode up to her husband and hugged him. She kissed him on the cheek and said, “Tha was gweat!”
Shining blushed again and said in repky, “Thank ya, but I was twying to make it bigga.”
Cadence giggled and replied, “Thas okay, ya a wittle foal now.”
Shining kissed Cadence on the cheek, receiving dawws from the crowd.
Twilight then lifted the two and Flurry back into the foal buggy as she cooed, “Alright, it’s time for the birthday party.” She then carted the three foals to the royal dining hall. Along the way, Shining was getting a bit cranky as he whimpered and kicked his back legs a bit. Twilight gasped, “Oh I forgot about your paci!” She then came up and popped a pacifier in his mouth. Cadence started to cry as Twilight sighed, “Oh Cady, you want one too?”
Cadence nodded, as a pacifier was into popped her mouth too, making her grin as she gave her paci a few good suckles. Flurry then began to cry as Twily instantly placed a smaller pacifer in her mouth. She then sighed as Shining started to feel his wet bottom become more irritated.
“Twily can ya change me?” Shining Armor babbled.
Cadence looked down to see that her diaper was soaked and asked, “Ya Twily can I get a diapee change too? I tink I wet mowe than Shiny. And I tink Fwurry Heawt did a messie in hew diapee.”
“Oh, does wittle Shiny need a diapee change?” another light singsong voice responded.
Shining looked up to see Twilight Velvet trotting through the crowd with a motherly smile. He gasped, “Mama?”
Twilight Velvet teared up a bit and whispered, “Yes, it’s Mama, sweetie.
Night Light came up behind her and dawwed at him as Shining tried to cover his wet diaper his father just smiled at him. “Hello, Shiny, and Flurry, and Cady. Do you three need diaper changes?”
Cadence became really excited along with her daughter who both squealed and started kicking in the foal buggy.
Shining became really embarrassed as he tried covering his diaper with his forelegs. Then Twilight Velvet carried them to the closet bathroom where there was a changing table. Twilight Velvet started changing Flurry while Shining sat back in the foal buggy. “I‘ll get to you in a second, Shiny. You’re just wet, Flurry Heart’s messy.” she told him.
Cadence was taken by Nightlight as he nuzzled her and cooed, “Who’s the big filly?” She giggled in response and cried, “I am a bi fiwwy.” Twilight came over to her dad and helped him change Cadence as she started to get fussy as they cleaned her up.
Shining, seeing the rest if his family getting all the attention, spat out his pacifier and began to wail. Twilight sighed and came over “Hey Shiny, what’s the matter?”
Shining cried, “I wana diapee change!”
But just then, Night Light, having finished with Cadence, placed her back in the foal buggy. He strapped her in and kissed her on the forehead. After he slipped her binky back in her mouth, he then levitated Shining to the changing table. “Oh, it’s been so long since I last changed your diaper,” he said with a chuckle. “Usually your mother would take care of it.”
Shining squirmed, only making Twilight Velvet giggle. “Oh, you’re so adorable,” she cooed at him. “How long has it been since you and Twilight were my sweet little foals, running around and getting into trouble?” Then both of Shining’s parents proceeded to change his diaper. Night Light took off his wet diaper and wiped him down, then Twilight Velvet put foal powder all over his rump, along with foal cream. Then Twilight Velvet hugged him and and helped him into the foal buggy.
With the changing process complete Twilight declared, “Alright you two, time for cake.”
Cadence bounced happily in her seat shouting, “Cake! I want cake!”
Twilight then took the three into the dining room where Luna and Celestia stood over a huge pink cake. Cadence squealed kicking her hind legs babbling, “I wan some!
Twilight Velvet laughed as she used her telekinesis to lift the three into seats around the table, while Night Light placed bibs around the three.
Cadence looked up at her aunts and asked, “Did Twily tell ya about my wittle supwise?”
Celestia giggled and replied, “Of course, and Luna and I wanted to chip in and care for you three.”
Shining eyed them, “Why? Don ya hawe a kingdom to wun?”
Luna cooed, “Oh shiny you have such an adorable lisp and look very cute in your diaper. Don’t you worry, we’ve left the kingdom in Fancy Pants’s capable hooves.”
Flurry and Cadence giggled as Shining crossed his hooves over his diaper. Then Celestia announced that it was time to sing.
They all sang happy birthday to Cadence as they brought the cake to her with candles growing bright. After the song was over the cake was brought forth and given to Cadence. She babbled, and tried touching the cake, prompting to Twilight Velvet to giggle, “No no, Candy, you got to blow the candles out.”
Cadence looked at Twilight Velvet, as Twilight Velvet came up to the candles and puffed on them, Cadence giggled and spat at the candles, and they were snuffed out. This made the rest of the ponies to laugh.
Celestia then cut the cake, and Twilight took out three bottles of milk.
Night Light took a piece of cake and with a rubber fork he levitated the cake into Shining’s mouth, “Here you go, Shiny.” he cooed.
Shining opened his mouth and he let the cake enterit. He smiled with content as Twilight Velvet took a rubber fork and started to do the same for Cadence. Twilight herself gave Flurry Heart a bottle of milk and helpet her hold it as she suckled greedily.
While Night Light was feeding Shining the foalfied prince turned to his wife and asked, “Ya wike the cake?”
“Is vewy yummy.” Cadence replied with a huge grin, covered in frosting. Shining laughed, “Ya got fwosting all ova ya face.”
That prompted Cadence to use her tongue to try and lick some off her face. Flurry watching her mom, began doing the same thing, as she tried licking the frosting off her face. Shining looked down at his hooves also covered in frosting, and he then took them into his mouth and began to suck on his hooves.
Night Light came up to his son with a wet rag, cleaned his face, and then gently took the hooves from his son’s mouth. Shining began to whimper but Night Light took a pacifier and placed it into his son’s mouth and let him have a few good suckles to calm down. Night Light then came up and kissed him on the forehead and brushed his mane a bit, “There there, you're alright now.” he told him.
Twilight smiled as Celestia said to her, “Well, Twilight, it looks like the spell worked perfectly.”
Twilight blushed at the compliment and stroked the ground with her right hoof, “Thank you, but I think it worked a bit too well.”
Luna giggled seeing that Cadence was now sukling her hooves. Flurry Heart though, was getting cranky and started to cry. Twilight came up and picked her up with her telekinesis and hushed her. Then Twilight Velvet turned to her daughter and asked “Can you take Flurry?”
Twilight smiled, “Of course, go help Shining and Cadence enjoy today.”
Cadence looked up at Flurry, then she and her husband were taken by Twilight Velvet’s magic into another room. It was a royal chaning room, and as Luna and Celestia followed they took Cadence with their magic to dress her up, as Twilight Velvet and Night Light took Shining and did the same.
Cadence was dressed in a poofy white dress with a foal bonnet, and her mane tied into two pigtails. Shining’s mane was curled and brushed into a single infantile lock with a blue bow. He was dressed in his royal suit but this one was designed for foals as the sleeves were poofy, and at the end was a button crotch that came up around his diaper. He blushed seeing himself in a mirror with his mom cuddling him and dawwing, “Oh sweetie, you’re adorable.”
Cadence turned to her husband and laughed out loud, but was soon being cuddled by Luna and Celestia who were both cooing over her. Then they both waddled together out through two doors in the back of the room. They came to the throne room once again with all the nobles cooing over the two. They blushed as they came to the center chamber with the princesses watching over the couple. Cadence turned to her husband and whispered, “you do wook adowable.”
Shining giggled and replied jokingly, “So do you.”
Cadence smiled, “Wana dance?” she asked.
Shining bowed, “Anythin fow ya biwthdaw.” He then took her hooves and they started to waddled around. The rest of the crowd hushed as the two waddled together then the crowd became quiet and the two continued to dance, not caring that they were wearing diapers or foal clothes. They didn't seem to notice anything else but the crinkling their diapers made and the puffs of foal powder that drifted around them. Shining smiled at his wife, then gasped as he suddenly lost his balance and fell on his padded bottom, as Cadence did the same.
Shining looked at his wife and gave her a smile, then Cadence came in and kissed her husband on the lips. The two held the embrace for quite some time as the crowd dawwed. Cadence then fell towards her husband and Shining rubbed his head into her shoulder. Twilight Velvet then took the two in her telekinesis and strapped them into the foal buggy. Cadence kissed her husband and whispered, “thank ya fow doin this.”
Shining giggled and kissed his wife back and whispered, “Yow wewcome, it was kind of fun.”
Cadence then fell into Shining’s locking forehooves as the buggy started to roll and the two were soon sound asleep.
Shining woke up and saw that he was in his bed, then he looked around the room and saw that it was like it was before he went to sleep the previous night. Then he heard laughter. He looked up to see Cadence, Twilight and Luna standing over him and shouted, “You three made that dream?!”
Luna giggled and confessed, “Oh Shiny, you were so cute. And of course we did it.”
“How was it?” Twilight continued, “Did you enjoy it?”
Shining looked at Cadence, who was giving him a sweet smile, and he blushed, “I admit, that was pretty fun. Now that I think about it, Flurry Heart could really use a playmate.”
Twilight laughed and Luna nodded. Then Cadence asked, “Funny, you should mention that. Would you...would you mind if you act like a foal for me, just for a little bit? Nopony will have to know, just the four of us and Flurry Heart. Next night we can swap roles.”
Shining smiled and replied, “Fine, I’ll act like a foal for a while. But don’t mess with my mind. So no spells! Okay, Twily?”
Twilight giggled and replied. “Alright, deal.” And she and Luna left without another word.
Cadence then took out a giant, poofy, white diaper, then came over to her husband and cooed, “Alright, Shiny, open your legs,” Her husband obeyed, then she started to place the diaper around his rump as she asked, “Does that feel good?”
Shining looked down, seeing his fresh diaper, and kicked his hind legs and giggled at the crinkling sounds it made. He then looked at his wife and in a fake lisp whispered, “Yeah it feews gweat, thank ya Cady.”
Cadence gave him a motherly smile and cooed, ”No problem, Shiny. Now, why don’t we go see Flurry Heart?”
