Baby Shine and Daddy Sun

Chapter 1: Baby Shine and Daddy Sun

Shining Armor was in his office as he finished with all the paperwork. He looked at the tower of documents he has just finished with and sighed in relief. Just one more and he would be free.

A gentle knock on the door called his attention as he finished putting his stamp on the last document.

“Come on in!” he said, as he placed the last document on the top of the tower.

Sun Burst opened the door as he shyly greeted his friend. “Hello, my Prince, is this a bad time?”

Shining Armor smiled. “Come on Sun Burst, you know you don’t have to be so formal with me. We’re friends, remember?”

Sun Burst nodded shyly. “I guess I can’t help it. Old habits die hard.”

They both chuckled as Shining patted his friend’s back. “So, are you ready for ‘Guys night’?”

Sun Burst grinned. “I’ve been waiting the whole day. I have something I know you would love!”

“Is that so? What is it?”

“Let’s just say is a big surprise. Or rather I say ‘small surprise’? You just have to be patient.”

Shining raised an eyebrow and giggled. “Now you got my attention. Sounds like fun.”

“You’ll see soon enough. Now come on.”

They both exited the office as Shining turned to the two guards on the door. “Thank you for your hard work. I know it’s been a long shift guys. Go home, spend time with your families, or whatever. Just enjoy yourselves, you earned it!”

The two guards saluted their Prince. “Sir yes sir! Thank you, sir!”

With that Shining and Sun Burst started to walk to their secret hideout. Shining’s ‘Stallion Cave’.

“So where is her Royal Highness?” asked Sun Burst, doing some small chit chat as they get there.

Shining shrugged. “Girls Night. It’s been a while since we have a whole weekend for ourselves, so today we hang out with our own friends, and tomorrow we’ll spend the day together.

Sun Burst nodded in agreement. “Sounds like a good deal. Is a good thing Twilight volunteered to watch Flurry this weekend. I can tell you both needed it.”

Shining nodded happily. “Faust bless my little sist!”

They finally arrived to Shining’s stallion cave. The top room of the smallest tower in the castle. A private paradise where Shining can spend some quality time with his buddies that Cadence graciously granted him.

But after Flurry was born, he had less time on his hooves and now the only friend who spent time with him at his ‘cave’ was Sun Burst, but it was okay. When it comes to friends, quality over quantity was always better.

Shining opened the magic lock and look around to make sure nopony was near, and then he rushed inside followed by Sun Burst, who was chuckling. Once Sun Burst entered the room, Shining rushed to lock the door and sighed relieved that nopony saw them.

Sun Burst Cooed Shining as he stroke his mane. “Aww, is my little colt ashamed of something? Come on, tell me. You can trust daddy!”

Shining blushed as he sucks his hoof. “Sowy dada! But chu know I have a weputation to keep!”

Sun Burst gasped in surprise. “Oh my! What a big word for such a little baby! You are so smart. Daddy is so proud, you deserve a reward!”

“Yey!”

Sun Burst took Shining to an oversized changing table in a corner, one of the many new elements of Shining’s cave alongside a drawer full of diapers, a toy chest, a rocking human, a highchair big enough to fit an adult and the center piece, a huge crib.

Shining started to climb on the changing table but Sun Burst stopped him with a gentle pat on his head.

“Hey what do you think you’re doing, Baby Shine?! You can get hurt! Dada would help you!”

“But Dada…”

“No buts! Daddy knows best!”

Sun Burst then closed his eyes and concentrated his magic on his horn to lift Shining Armor. The yellow stallion was huffing and puffing struggling against Shining’s weight, but he managed to put him on the changing table.

Sun Burst took a deep breath. “Uffff! You are growing up so fast! In a couple of years daddy would not be able to lift you at all!”

Shining suck his forehoof, as he kicked in protest. “No Dada! I wike when chu cawwy me!”

Sun Burst cleaned his sweat with his cape. “I know my baby, we still have plenty of time!”

“Yeeeey!” cheered Shining Armor.

Then Sun Burst put a giant pacifier on Shining’s mouth as he started to get his changing supplies. Wipes, rash cream, powder and of course a big puffy diaper with a butterfly pattern on it.

Shining frowned at the sight of the diaper and shook his head.

“Is something wrong, Baby Shine?” asked Sun Burst.

The white stallion removed his pacifier and glared at Sun Burst. “Sun Burst, we’ve been through this. No girly clothing. I am a baby colt, not a filly!”

“Aww, but they are so cute! Think of how adorable you would look while wearing them!”

“No means no. Come on Sun Burst, I’m tired of having this conversation every time you bring me here.”

Sun Burst sighed and pulled out a diaper with a blue lions design instead.

“Better?”

“Better!” said Shining with a smile.

“I’ll convince you one of these days!” said Sun Burst, as he opened the rash cream and started to apply it.

Shining shivered at the contact of the cold cream and the soft touch of his friend’s hoof pressing against his crotch. He put on the pacifier to hold back an upcoming moan.
Sun Burst smirked at this and continued to rub the cream against Shining’s most sensitive area causing his penis to grow hard. Shining blushed, as Sun Burst applied more cream on his hoof and started to give Shining a gentle stroke.

Shining moaned behind his pacifier much to Sun Burst’s delight.

“Is Baby Shine enjoying himself?”

Shining nodded shyly.

“Mhmmmmm…”

“Do you love daddy?”

The white unicorn nodded again and Sun Burst started to struck him faster.

“Show me how much you love me!”

Shining shivered and squirmed as he went close to climax. And then Sun Burst stopped and started to put some powder on him instead. Shining pouted, Sun Burst always did this to him.

Finally, the yellow unicorn lifted Shining’s legs and put the puffy diaper underneath to finally taped it around his waist.

“Now my baby is all protected!”

“Thanksh Dada!”

Shining sat on the changing table and started clapping his forehooves. “Dada! Chu fowgot about my shuwpwise!”

“A surprise? Did I say something like that?”

Shining pouted again. “Chu chust being mean! Chu shaid chu have a supwise fow me!”

Sun Burst giggled as he struggled to put Shining on the floor with his magic. “I know. Is a very special surprise but daddy cannot give it to you until I change your diaper.”

“Awww, weally?”

Sun Burst then pressed his hoof against Shining’s diaper. “Yes, but I know my little colt cannot hold it for long. Especially if daddy helps!”

Shining blushed. “Yes daddy, pwease hewp!”

Sun Burst sat on the floor and Shining crawled to his lap. Sun Burst hummed a tune as he pressed his hoof against the bigger unicorn’s diaper. Shining moaned more behind his pacifier, much to Sun Burst’s delight. Then Shining started to get fussy, getting more and more impatient as his diaper was too thick and he barely felt anything. But daddy Sun Burst wasn’t over yet. He focused his magic on Shining’s massive dick and started to stimulate it under the diaper, giving Shining a must needed relief.

“Oh… did my baby made stickies on his diaper?”

“Yes I did Dada! Change pwease!”

“Not yet, this diaper is too dry to earn a change yet!”

Shining pouted again.

“Hmmmpff!”

“Hehe, you look so cute when you’re mad Baby Shine!”

Shining just frowned and turned his back at him and crawled to the toy chest to pick up some blocks to make a tower.

Sun Burst couldn’t help but smiled looking at his friend happy that he had this time to leave all worries behind and simply enjoy being taken cared of. Back when Sun Burst introduced him to the idea of being babied, Shining was on the verge of collapsing. So tired that he was willing to do anything to relax.
And much to his surprise, becoming Sun Burst’s little foal was just what he needed. It started with just letting Sun Burst putting him into a diaper and play with the toys Flurry didn’t play with anymore. Then they continued to get more into the role with bedtime stories, feeding, dressing up and eventually Shining finally allowed Sun Burst to change his wet diaper. From that point on, they started to transform his ‘cave’ into his nursery.

His brand-new paradise.

“Cute! You really needed this, right my friend?” mumbled Sun Burst to himself. “And maybe one day you’ll let me turn you into my little princess!”

“Not happening!” said Shining, turning to Sun Burst.

“Hey, naughty colt! Were you eavesdropping?”

“Is not just for you if you say it out load!” said Shining sticking his tongue at Sun Burst.

They both laughed.

“Baby Shine, how’s your diaper?”

“Wet!” he smiled. “I just drank a ton of water before you showed up to my office!”

“Good, you know what this means?”

“My supwise!” cheered Shining, with his baby voice.

“That is right. Come here Baby Shine!”

Shining happily crawled to Sun Burst who went to get a changing mat.

“Sorry baby, I know you love the changing table but you are too heavy!”

“Yeah, let’s just keep using the mat. Or let climb in the table.” said Shining with a chuckle.

Sun Burst extended the mat for Shining to lay on. With a teasing smile, Sun Burst started to slowly undoing the diaper tapes as Shining sucked his hoof.
Finally Sun Burst opened the diaper, revealing Shining’s full stallionhood soaked in urine and cum but Sun Burst didn’t mind. Without saying a word, he took a package of wipes and started to clean Shining up, making sure to stimulate him with every wiping.

Shining squirmed again, enjoying the attention Sun Burst was giving to his most sensitive parts. When he finished wiping, it was time to apply the powder and more cream.

Sun Burst made sure to keep rubbing Shining’s cock both with hooves and magic, until Shining couldn’t hold it anymore and came. He fell on the mat breathing heavily.

“Hey you usually don’t let me cum unless I do it in my diaper! Is this my surprise?”

“Not quite. This was just a little treat for being such a good foal. The real surprise is here!” said Sun Burst pulling out a purple gemstone from his cape.

Shining tilted his head. “What is that?”

“You see, Starlight, Maud and I have been doing some research about the magic properties of certain gemstones. And this stone in particular has the unique property to amplify any spell the user makes while holding it. Sadly it can only be used once and then it turns into a normal rock. I was thinking we can use it to make this whole experience more realistic.”

Shining looked at the gemstone. “But you said it can only be used once.”

“No worries, I have two. See?” said Sun Burst taking a second rock from his cape.

“So are you going to turn me into an actual foal for today?” asked Shining excited.

“Well… not really. Age spells are very complicated, and I don’t trust my abilities enough to actually try that. No, I was thinking in something far simpler. A shrinking spell!”

“What?”

“Yes, I can’t turn you into an actual foal but at least I can shrink you down to their size. Not only you can have twice as fun but it will make things easier for me too. I would love to pick you up and carry you but you know is impossible for me to do it. Unless…”

Shining smiled. “You know what? Let’s do it! Sounds like a lot of fun.”

“Great! I knew you would like the idea!” said Sun Burst holding one of the gemstones as he charged his horn.

“Wait!” called Shining.

“What?”

“If I’m going to be foal-sized, can you diaper me on the changing table?”

Sun Burst smiled. “Of course, Baby Shine!”

Shining closed his eyes waiting for it and then Sun Burst fired the spell. A tingling sensation ran all over his body as he felt like falling. He opened his eyes to see everything around him getting bigger and bigger. Then he focused un Sun Burst, who was now towering over him.

“Well look at that! My own foal-sized adult foal!”

Shining nodded. “It really worked! I’m actually tiny.”

Sun Burst then lifted with his magic. “And light! Hehe, look! I can pick you up as easy as I pick Flurry!”

Shining Armor felt a bit dizzy. He was way too far from the ground. Sun Burst quickly noticed his baby’s discomfort and went to put him on the changing table.

“Thanks Dada! Being smaww ish scawwy!”

“I know it must be. Luckily Dada Sun Burst is here to help!”

Shining look around from the changing table, it almost felt like looking through the window at one of the towers. He was really that tiny!

“Oh wow, I must be Flurry’s height now.”

“Well, not exactly, I made you an inch shorter than her!” said Sun Burst proudly as he started to put a new diaper on Shining Armor.

“Wait, what? Why?”

Sun Burst then pulled out a tiny yellow dress with a tutu from one of the drawers.

“So you can fit in her old outfits of course!”

Shining shook his head. “No, no, I told you already that I would not wear filly clothes!”

Sun Burst simply picked him up, as Shining tried to struggle against his magic. When he figured it was pointless he tried to use his own magic to get free but realized that his magic have shrunk too.

“Hey no! NO, I am telling you, I will not play anymore!”

Sun Burst ignored his pleas and stuffed him on the dress. It fit like a glove, just as he planned.

“See? That’s not so bad, isn’t it?”

“So this is the real reason why you shrunk me!” protested Shining.

“No, is one of the reasons. But my main reason is just to have more realism to our game. Come on Shining, don’t you trust me?”

“I do but…”

“Then there’s nothing to worry about. Now let’s go back to your toys my little princess!”

He place Shining on the floor and he crawled to the blocks he was playing with before. The tower he made was so tall that he could no longer stuck the blocks with his hooves at his current size, so he opted to use his magic.

They were heavier than expected, but that was because his magic was now equivalent to his current size so there wasn’t much he could do about it. At least he still had perfect control.

“That is what I call a castle!” suddenly said Sun Burst. “Is that your castle my pretty princess?”

“Yes, it is!” said Shining proudly.

“Good! It would be a shame if a dragon come out of sudden to attack!” said Sun Burst pulling a hoof-puppet from the toy chest and started to chase Shining.

“Aww no!”

He started to crawl away from Sun Burst as they two of them giggled. But when trying to escape, Shining tripped with the tutu and fell.

“Oh no!”

Sun Burst captured him and began tickling him with the puppet. “Nom, nom, nom, nom! What a delicious princess, nom-nom!!”

“Ehehehe, Noo! Hahahaha! Hewp! Hehehem! He is eating me!” said Shining between laughs.

A hissing sound made them stop.

“Aww, did my Princess wet her diaper?”

“Is all your fault!” said Shining pouting.

“Maybe, hehe, but couldn’t resist such cuteness!”

“I am not cute!” protested Shining, crossing his hooves.

“Sure you are baby girl!” said Sun Burst picking Shining. He was about to take him to the changing table when his stomach growled.

“Is my baby hungry?” asked Sun Burst.

“A wittle” admitted Shining.

One more time Sun Burst sat on the floor and put Shining on his lap. He was so much lighter and easier to carry now. He then started to feed him a bottle of milk.

“There you go! So you can grow big and strong to take care of all the responsibilities of the Empire!”

“Hey this sessions are to forget about all that!” said Shining.

“I know, I know, just messing with you.”

Shining finished the bottle and much to his surprise, he was full. Usually Sun Burst had to feed him at least two bottles and three or four jars of baby food. But this time only one bottle was all he needed.

“Hehe, the advantages of a small stomach!” said Shining blushing.

“Yes, and small meals mean small messes too!” said Sun Burst patting Shining’s diaper.

“I still want my change!” said Shining.

“You are very demanding to be so little!”

“Can’t help it, I’m a Princess!”

The two stallions giggled and Sun Burst finally burped Shining. Despite the dress, he was in heaven as usual. In the end the shrinking was okay but it didn’t do much for the experience. The only advantage was that now Sun Burst could easily carry him and dress him in whatever he wanted.
But as for Shining, he was sure he won’t do it again.

Sun Burst started to change Shining’s diaper as usual, when suddenly the door opened letting a very drunk Starlight and a slightly tipsy Cadence in.

“Hello boys! Do you mind if we join… “

They both went speechless as their eyes went all over around the oversized nursery, to finally fixing at the miniaturized stallion.

Shining covered his face with his hooves.

“No, don’t look at me!”

Cadence smirked looking strangely amused. “Can’t help it, you are just a cutie. Alright Sun Burst, care to explain what’s going on here?”
