Chapter 3: The fun would never end!

Sun Rays went through the windows and crystal walls, waking up Shining Armor. He found himself in an unfamiliar place with Cadence wrapping her hooves around him.

“Huh? Where I am?”

Than he noticed the dress and the incredibly heavy diaper he was wearing, and everything came back to him. He smiled reminding all the little moments. He could not wait to continue with the fun.
Shining turned to Cadence and started to shake her to wake her up.

“Cady! Cady, wake up!”

“Huh? Shiny? Where are we? And what’s that smell?”

Shining pointed a hoof to their nighttime diapers. “I think that’s us Cady”

“What?”

But then she started to remember last night and couldn’t help but smile. “Hehe, I must admit yesterday was one of the best nights of my life! We must do this more often!”

Shining nodded in agreement. “Yeah…”

Cadence pocked her diaper. “I’m still not convinced about messing myself but last night was great! So, what now?”

Shining crawled to the edge of the crib. “Hello? MAMA! DADA! WE NEED A DIAPER CHANGE!”

“YES, CHANGE PLEASE!” joined Cadence.

The door opened, allowing Sun Burst and Starlight in.

“Hello my little babies! Did you sleep well?” asked Sun Burst, picking up Shining.

“Hey Dada! I made a big mess in my diapers!” said Shining.

Starlight giggled as she picked up Cadence. “Sure, you two did, this milk is very especial. Whenever the baby is naughty it will make you mess. And I know you may get naughty after we leave.”

They both blushed and looked away.

“It’s okay! I’m glad you are enjoying yourselves! Now time for a change!”

They were taken to the changing table where they were laid next to each other. Shining started to suck his hoof as Sun Burst untapped his diaper.

“Ufff! Shining what a stinky little boy you are! Just look at all this mess!”

He used his magic to open the diaper and started to wipe Shining slowly taking especial care around his cock that immediately got hard at the gentle contact.

Shining squirmed at the wipe stroking his little dick. “Hmmpf, Dada!”

“Oh look at that you are about to make stickies too? You must really enjoy being messy!” chucked Sun Burst throwing the wipe and taking a new one to continue to change Shining Armor.

When the white stallion was all clean, Sun Burst took a bunch of cream with his hoof and started to apply it in Shining´s privates. Being extra careful around his cock and into his butthole.

Shining looked at the pot of cream and noticed it was quite different that the regular one they used. “That’s not our rash cream Dada!”

“Nope, is something extra especial today Baby Shine! Don’t worry I promise you would enjoy it!”

Shining shivered and smiled happily. Sun Burst then wrapped a new thick diaper around his waist. “There you go! A clean baby is a happy baby!”

He then put Shining into a cute pink onesie with purple trim.

In the meantime, Cadence was being taken care you by Starlight who was making sure her whole privates were all covered in cream. Then she put on the powder and taped a new diaper.

Starlight happily patted her diapered rump and put her on a matching onesie with Shining’s.

“There you are babies! All nice and clean!” said Starlight.

“Thank you, Dada, Mama!” said Cadence.

“Yes, thank you!” said Shining relieved. “I swear I’m never going to get used to mess my diapers!”

“Oh, don’t say that Baby Shiny! You may start to love messing your diapers!” teased Starlight.

“Not happening any time soon!” said Shining.

“We’ll see about that!” joked Starlight.

Then Cadence and Shining were placed on a high chair as Sun Burst brought two jars of baby food.

“Time for num-numbs babies!” announced Sun Burst.

The Royal Couple smiled as Starlight put a bib on each of them.

“Here comes the pegasus!”

They started to feed them.

“Eww!” complained Cadence after the first spoonful. “Does all baby food taste like this? Gross!”

Shining didn’t say anything. He was already used to the taste.

“Shiny, from now on we’ll feed Flurry home made baby food! This is nasty… my poor baby doesn’t deserve it!”

“Agree!” said Shining as Sun Burst forced him another spoonful.

Starlight offered them a bottle when they finished their foul meal. “What about some delicious milk to remove the taste from your mouths?”

“Thank you!”

They both grabbed the bottles with their magic and started to drink.

Suddenly they stopped. They have been feeling strange for a while, with both their crotches feeling increasingly hot. They couldn’t concentrate anymore. They suddenly released their bottles and desperately started to rub their diapers.

“What is it my babies? Feeling hot?” asked Starlight.

“What is on this milk?” asked Shining rubbing his diaper harder.

“Is just normal milk! The rash cream on the other side… I mixed some aphrodisiac cream too!” said Sun Burst.

“You…”

The two shrunken ponies started to desperately rub their diapers with their tiny hooves, but they were too thick. They could barely feel anything. Then they tried to use their magic to get the most wanted release but they were stopped by Dada Sun Burst and Mama Starlight who put their hooves on their horns.

“Mama!”

“Dada!”

Starlight smirked and started explaining. “Sun Burst and I discussed this last night. You two had so much naughty fun without our permission, so we decided you are not allowed to cum until we change your diapers!”

“And not just wet. A very messy diaper to earn your change!” added Sun Burst.

The two shrunken ponies looked at them with tears on their eyes.

“Awww babies don’t look at us that way!”

“Yes! It is what you signed up to when you asked us to shrink you! We’re in charge!”

Without a word, they were placed on the floor.

“Just be good babies and play with your toys. Mama and I will watch you to make sure you don’t use your magic for naughty things!”

Shining turned to Sun Burst. “But Dada, I cannot open the toy chest without my magic! I am too small!”

Starlight gasped. “Oh sorry babies! Luckily Mama and Dada are here to help!”

She used her magic to open the chest and drop all the content on the floor. “There you go, enjoy babies!”

Trying to ignore the increasing need, they both picked a puzzle and focused all their attention in solving it. But they simply couldn’t. Before he realized, Shining Armor took a piece and started to press it against his diaper just trying to feel something. Cadence then put her diapered butt against a corner, crying.

Sun Burst and Starlight giggled at this and playfully teased their littles.

The yellow unicorn lifted Shining’s tale and pressed one of the puzzle pieces right where his butthole would be. The stallion shivered and fell, breathing heavily due to the increasing horniness.

“See how much of a filly are you? Wanting Dada to play with your little tight hole!”

Cadence couldn’t take it any longer. Especially after Starlight started to send magic vibrations on her diaper stopping right when she was about to climax.

They couldn’t hold it any longer. With their faces red of embarrassment, the Royal Couple held hooves and started to push. Their efforts finally got rewarded when a small lump appeared on the bottom of their diapers.

Sun Burst stroked Shining’s mane. “Awww Baby Shine, did you pooped your little diaper on purpose?”

He did not respond. He just looked away in embarrassment.

“Right after he said he won’t do it, right?” giggled Starlight. “At least my stinky little Princess did not complained like a good baby girl!”

Cadence was about to protest but she was too horny to argue. She simply begged for a change.

“Change me please! And let me cum! Let me cum and then change me!”

“Okay, okay! A deal is a deal!” agreed Starlight.

The couple of unicorns lifted their babies with their magic. Shining and Cadence helplessly waddled their hooves in the air when suddenly they pressed the back of their diapers against each other.

Shining and Cadence gasped in surprise, but then started moaning when they felt their caregivers using their magic to make their diapers vibrate. On Shining’s diapers, the vibrations were concentrating on his asshole, making him shiver and neigh in pleasure. The smelly mush suddenly wasn’t as annoying and yucky as before, even if it was spreading
Starlight of course focused in rubbing Cadence’s pussy and clit as she was making sure the content of the diaper spread all over her.

The orgasm was so powerful that the shrunken couple even released a wave of magic power and fainted.

Starlight and Sun Burst smiled looking at their little foals.

“Look at that! They look so happy and relaxed!” said Sun Burst. “They really needed this!”

“I know, right?” said Starlight with a smirk. “Imagine how stressed they must feel all the time, to the point to surrender all control and adult decision to us. If only there was a way to keep helping our friends forever!”

“I am pretty sure they would organize more playdate like this!” said Sun Burst, oblivious.

“You are right! Let’s just make them happy now than we can!”

Sun Burst smiled placing Shining on the changing table. “Let’s start by changing these two babies.”

“Sure!”

They start cleaning them up.

“Sun Burst a diaper change won’t do for such a big mess! They need a bath!”

“Starlight, what a great idea! Wait here!”

She nodded as Sun Burst ran downstairs to get Flurry’s baby tub, baby shampoo and some toys as Starlight watched the two of them.

Sun Burst came back a few moments later and placed all of the supplies on the floor and then go fill the tub with warm water. Starlight opened a bottle of bubble bath and put it on the water creating a bubbly paradise for Shining and Cadence.

“Shall we wake them?” asked Sun Burst.

“Why? It would be funnier this way!” smiled Starlight.

Sun Burst nodded, and suddenly the shrunken couple was woken up by being dropped in warm water. They gasped in surprise but didn’t have the time to ask what was going since their caretakers starting to scrub them and make them all nice and clean.

None of them said a word. Shining and Cadence just closed their eyes and enjoyed the bath as they occasionally play with the toys around them.

When Starlight and Sun Burst finished with them, they wrapped them in a towel and put them on them the changing mat as they pulled out new diapers, rash cream and powder.

“Please no more aphrodisiac cream!” pleaded Shining.

“What do we say about us being in charge?” asked Starlight.

“I am just asking like a good baby should!” apologized Shining. “I did not mean to be rude Mama!”

“Yes Mama! Please, we don’t think we can take that again!” pleaded Cadence.

“Oh, okay then! Good work babies, you know your place!” said Starlight. “No worries, this time you get normal rash cream I promise!”

Cadence and Shining sighed in relief, then exchanged a look and giggled as they got diapered.

“You know? Except for the diapers this felt pretty much like going to the spa!” said Cadence.

“Like a couple massage!” agreed Shining.

Sun Burst and Starlight exchanged a look.

“Massage? We can do that!”

“Really?”

“Anything for our babies!” assured Starlight. “Lay there!”

The Royal couple obeyed, as Starlight and Sun Burst started to massage their tiny bodies with their gigantic hooves. Sun Burst knew was the most skilled of the two of them since he used to give Flurry a massage for babies, and he was guiding Starlight giving hints there and there.

A moan of relaxation came from Shining and Cadence.

“Thank you so much, Sun Burst, Starlight!” said Shining after a while.

“Hey, our names are Mama and Dada!” teased Sun Burst with a chuckle.

“Hey just let me break character for a little!” said Shining. “I am very thankful friend, this idea of yours was the best way of relaxing I’ve ever known. And with this spell of yours you just made it extra naughty. And Starlight! Where do I start? Thanks to you I got to share it with my wife. I can’t thank you two enough.”

“Me too!” said Cadence. “I never thought being treated like a foal felt this relaxing… and kinkily humiliating. Now Shining and I have a new way to spend time together and we must thank you for that!”

“You’re welcome! Anything for a friend!” smiled Sun Burst.

Starlight nodded happily nuzzling them. “Of course! what are friends for?

The whole group giggled happily.

“I would love to keep having playtimes with you two as our caretakers.” continued Shining. “It’s a shame we can’t always do this shrinking thing, but we can play pretend.”

Cadence theatrically sighed. “It’s a shame though! I really liked being this small! Speaking of which, how long until the spell wears off?”

Starlight raised an eyebrow. “Wears off? My dear Cadence you must be mistaken! This is not a ‘shrinking spell’. It’s a ‘srihiking curse’! Curses simply don’t wear off. They had to be cancelled by the pony who made them!”

“Wait, what?!” they shrunken ponies gasped.

“No way!” protested Shining.

Sun Burst smiled condescendingly at him. “Oh Baby Shine, come on. Remember what I told you that I would need another gemstone to grow you back to normal size? Why would I need to do that if it was a simple ‘shrinking spell’? It was obvious if you think about it!”

“But didn’t you use that spell to shrink Cadie?” asked Shining looking at Starlight.

The pink unicorn shrugged. “Whoopsie!”

Then Shining and Cadence hugged each other looking up at the two unicorns who simply took them on their hooves and rocked them.

“Pssst, it’s okay babies! You like being small, you said it yourselves right? So now you can enjoy your new size and new life forever and ever!”

Cadence tried to struggle against Starlight’s magic grip. “No, stop! Turns us back! Turn us back now!!”

“YOU CAN’T DO THIS TO US! WE’RE…”

Starlight and Sun Burst shoved a pacifier on their mouths and forced them into a stroller making sure they were all strapped and secure.

They pushed the stroller out of the nursery as Cadence’s and Shining’s eyes widened.

When they exited the room, they were greeted by a large group of ponies. Both their servants and their soldiers who were called by Starlight and Sun Burst to see the show.

Shining and Cadence started to fight again, trying to use their magic to get free, but Starlight and Sun Burst were prepared.
Starlight casted her anti-constipation spell making them both helplessly mess their diapers. Sun Burst by his way started to send magic vibrations to their diapers rubbing their genitals.

The effect was immediate. Cadence and Shining did not fight anymore and started to squirm and moan in pleasure instead much to everypony’s amusement.

Everypony around started to laugh. They knew that behind closed doors and after all the affairs of the Empire were dealt with, their Princes and Princess liked to relax by being submissive to somepony else. Must of them have participated on those sessions from time to time and they knew how much they liked being demeaned and dominated.
Sooner or later it would bite them in their butts. Now diapered butts.

Hearing everypony laugh just make things worse as they helplessly climaxed in their messy diapers in less than a minute.

Finally they were taken to the throne room where the servants have prepared a changing mat and changing supplies already. Again, a large crowd of Crystal ponies have gathered in the room ready to watch the show.

“Aren’t you excited babies? Everypony is here to witness how you traded your crowns for a diminutive size and lots of diaper changes!”

They put them on the mat and proceeded with the public diaper change.

Shining looked at Sun Burst for the last time as he winked an eye at him. “Imagine how happy Flurry would be when she returns home only to find she have a brand new baby brother and sister!”

“And who knows? Maybe another sister if her nosy aunt sticks her nose in my business again! Look at the bright side, the fun would never end!”
