Mommy's Baby Boy

“Cadance I just don’t think now is the right time.” Said Shining Armor as he made his way through the halls of the Crystal Castle.

Princess Cadance was following right behind him, looking a little annoyed.

“But why not? Flurry is going to be potty training soon. She’s growing up so fast. I think it’d be good for her to have a playmate.” Said Cadance.

Cadance was trying to convince Shining to have another baby.

She saw her daughter growing up so quickly and it made her a bit sad.

Before long Flurry would be potty trained, then starting school, then getting her cutie mark, dating, taking on royal duties, and so forth.

She wanted to experience being a Mother to a foal for a bit longer.

“You’ve seen how much has happened since Flurry has been born. She’s been in danger many times in her short life and will probably be in much more. I don’t think brining another baby into a world where we are at the forefront of protecting it is a good idea.” Said Shining.

“But we’ve always come out alright in the end, and I don’t think that’s something that’s ever going to change. I know it’ll be a bit more work but I know we can handle it. Please honey?” Said Cadance as Shining turned to face her.

“I’m sorry Cadance but I just don’t think now is the right time. Maybe in another year or two when Flurry is a little older and not as vulnerable. I have to go to a meeting now, but I’ll see you tonight ok?” He said as he gave Cadance a hug and kiss goodbye before continuing on his way.

Cadance stood there for a moment, annoyed by her husband’s words.

She had spoken to him a couple times in the last month about this and he just wouldn’t budge.

She kept fuming about it as she made her way back up to her private courters.

She understood Shining’s concerns, but she knew another baby was nothing they couldn’t handle.

She just had to figure out how to get Shining to change his mind.

She sat there, deep in thought for awhile, until a sneaky idea came to her, one that would work perfectly for her problem.

All she had to do was get some things ready.

The next morning Shining Armor was sitting in the living room of his family’s private courters, keeping an eye on Flurry Heart as she play with her toys on the floor.

He had the morning off from appointments and training, and was happy to be spending it with his beautiful baby girl.

He had been thinking about the conversation he and Cadance had yesterday. He was trying to think of how he could make it up to her.

He could tell she upset he didn’t share her desire to have another foal right now, but he was sure that waiting another year at least would be better for them.

They had just gotten use to the routine of taking care of Flurry and he didn’t think jumping straight into another baby was the best idea.

Still though, he loved Cadance and hated to make her upset. Maybe a vacation away or a new piece of jewelry would help to smooth things over and take her mind off things.

As he thought about this, he saw Flurry walking towards him, carrying a book with her magic and setting it in his lap.

“What’s up honey? You want Daddy to read you a story?”

Flurry nodded.

“Ok then. Let’s get you settled.”

He picked Flurry up and sat her in his lap, then turned his attention to the book.

He opened the book and began reading it out loud, but he began to notice something odd.

The further he seemed to get into the book, the more trouble he seemed to have with reading it.

Words that before had been all too familiar to him were now looking brand new and odd.

By the fourth page, he found himself unable to continue, the letters looking like gibberish no matter how much he tried to focus on them.

“Sorry Flurry. Daddy is a bit tired right now. He’ll read you the rest later ok?” He said as he picked her up and sat her back on the floor.

Flurry went back to playing with her toys, bored by the story not moving anywhere.

Shining couldn’t figure out what had happened. He had never been so tired that he couldn’t read before. He wasn’t even feeling that tired today!

He looked over at Flurry on the floor, playing with her plushie while she sucked on her hoof.

Shining Armor felt a strange urge as he watched Flurry. He felt the need to suck on something himself.

Shining could feel his hoof moving up towards his mouth and, without even thinking, stuck it in his mouth.

As soon as his hoof made contact with his mouth, he felt a happy sense of warmth and contentment fill him from inside.

He hadn’t sucked his hoof since he was a toddler, and with how rewarding it was feeling right now, he was wondering why he ever stopped. It felt amazing!

As Shining focused his attention back on Flurry, he saw that she now had the plushie in her mouth and was sucking on it.

Shining looked down at the foot of the couch and found another plush lying right by him.

He found himself beginning to wonder what the stuffed animal would feel like in his mouth. He wanted to know what Flurry was experiencing!

He got up and sat down on the floor, picking the plush animal up in his hooves and jamming in to his mouth.

The feeling was weird at first, but soon became pleasant. He ran his tongue over the plush’s soft surface and bit down slightly on it.

He wasn’t sure how long he had been sitting there as the plush absorbed his drool, but he soon found Flurry walking into his field of vision.

She looked at him and yanked the plushie out of her mouth, then babbled happily up at him.

Shining babbled happily back, then snapped back to reality.

He spat out the plush and shook his head, trying to reorganize his thoughts.
What was with him today?

Why was he acting like a baby?

Was he losing his mind?

Maybe he’d been working too hard lately.

He had been feeling stressed recently.

Maybe having a family and being Captain of the Royal Guard was a bit much.

He resolved to looking over his duties and maybe passing on one or two to his subordinates when he got into his office next.

As he made this decision he could smell something stinky in the air that he was all too familiar with.

“Come here Flurry. Let’s get you changed.” He said, scooping her up in his foreleg and walking into her nursery at the end of the hall.

He sat her on top of her changing table and got to work with due diligence.

In no time at all he had cleaned and stripped Flurry of her dirty diaper and had her powdered and taped in a fresh one.

He sat her down on the floor and Flurry wondered off to play with some of her toys that were on the floor in her bedroom.

Shining was about to follow her when he felt a familiar feeling coming from below.

He had to go to the bathroom.

“Stay here ok Flurry? Daddy will be right back.” Said Shining as he went further down the hall to the bathroom.

As he approached the toilet though, a strange feeling began to overtake him.

When he looked at the toilet, he suddenly felt very anxious and confused.

Although he had used the toilet countless times, he found himself not remembering how to use it.

He racked his mind, trying to remember what he needed to do, but couldn’t remember!

To make matters worse, his bladder was growing increasingly desperate to relieve itself, making the stallion squeeze his legs together.

While he franticly tried to figure out what to do, he found Flurry flying into the bathroom, her giant wings flapping about.

“Flurry I thought told you to-” He began to say as she flew down in front of his face and hovered there.

In her mouth was one of her diapers, folded up neatly.

He must have forgotten to close the door of the changing table.

He plucked the diaper from her mouth and was about to set it aside when he had a thought.

Flurry didn’t need to use the potty because she had her diapers, so why shouldn’t he just wear one?

But he was a grown stallion!

Stallions didn’t wear diapers. Much less use them.

The growing pressure in his bladder though was reaching the breaking point, and Shining realized he had no choice.

With a burst of magic, the baby diaper that was in Shining’s hoof vanished and reappeared around his waist, the garment now bigger in size to fit the grown stallion.

A moment later, the flood gates burst.

Warm pee entered the front of Shining diaper, making the garment swell and expand.

Shining just stood there frozen as it happened, feeling the pressure in his bladder lessen each second as the pee was absorbed by his diaper.

What occurred at the forefront of Shining Armor’s mind was not how silly he probably looked wearing and using the diaper or how gross it was that his urine was being contained and pressed to his crotch, but how much he seemed to be enjoying wetting his diaper.

A sense of security and safety swelled inside the stallion as he peed, just like when he had sucked his hoof.

It felt good to know that no matter what he did his diaper would be there, making sure he didn’t make a mess around him.

After a minute or two the flow ceased and Shining looked down at the diaper, swollen and wet around his crotch and butt.

He went to take it off but found himself stopping.

He found that he could no longer remember how to take the diaper off! The simple spell to remove it was no longer contained in his brain, as if it had been unlearned.

He tried focusing his magic on it and even batting at it with his hooves, but he could not figure out how to get the wet garment off of him.

Eventually he gave up, annoyed at his diaper and went to find where Flurry had gotten off to.

His diapered rustled with each step he took and swung back and forth between his legs from how much liquid it had absorbed.

Both only served to annoy Shining more at his current situation.

Here he was, a grown stallion walking around in a wet diaper.

He was sure when Cadance got home and helped him out of this he’d never live it down.

Emerging back out in the living room, he found Flurry flying around in the kitchen.

Using his magic, he grabbed the active little alicorn and sat her in her high chair.

It was about time for lunch anyway.

He set to work, warming her up a bottle and grabbing her some baby food.

He brought both of them over and sat them on the high chairs tray.

Flurry had just begun to be able to feed herself, granted in a messy and foalish way, but she did well with just a little help.

As Shining was about to set about preparing his own lunch, he gazed at Flurry with a strange fascination as she ate, suckling her bottle and spooning mashed up baby food with little coordination into her mouth.

What was once boring and simple foal food now looked super yummy!

Without a second thought, Shining prepared another bottle and grabbed a jar of baby food, taking a seat at the table with an audible squish and began to dig in just like he’d seen Flurry do.

He suckled on the nipple of his baby bottle, savoring the creamy formula as it trickled down his throat.

Then he scooped some mush up onto his spoon and spooned it into his mouth.

He hadn’t even bothered to try and read the label on the jar to see what flavor the food was.

All he knew was that the mush was yummy!

He spooned the baby food into his mouth with excited splendor, getting a good amount on himself in the process.

All the while Flurry watched her Daddy as he made a mess of himself.

She giggled innocently, thinking it was all some sort of silly game he was playing with her.

As Shinning finished the jar of food and his bottle, he sat at the table in a hypnotic state of bliss. He hadn’t had such a pleasant meal in such a long time, feeling so relaxed and fuzzy.

Through the mellow feeling, he heard Flurry saying something from her high chair, the baby filly having finished her own lunch.

“Pway! Pway!” She said to him.

Play. Yes, playing sounded like a great idea!

Using his magic, he brought Flurry out of her high chair and the two ran into the living room to continue playing.

Shining seemed to be extra focused on Flurry as they played, looking to the baby alicorn to show him what to do.

Little did he realize, but the more he watched her, the more things his mind seemed to forget how to do.

Names for things seemed to be changing in the stallions head.

Dolls became dowlies. Bottle became baba. Diaper became diapee. So on and so forth.

Skills that he had learned also began to change.

His ability to speak seemed to become further and further lost the more sounds Flurry made.

Not that he minded. It was so much easier to just babble and giggle incoherently.

The knowledge of how to write was lost when he and Flurry found some crayons and doodled on the wall. Words were dumb and boring. It was so much better to draw pretty pictures instead!

Tow hours later and Shining’s mind was a jumbled mess. Barely a coherent word or action could be found floating around the stallions head.

His mind was now almost identical to a one year old, focused only on fun and play.

He just sat on the floor in his diaper, drooling and babbling with his friend Flurry Heart.

As the two sat playing on the floor, they heard the sound of a door opening and closing.

A moment later, Cadance was standing next to the couch, looking down at them.

Flurry Heart beamed up at her when she saw her.

“Mama!” She said and ran into the grown alicorns outstretched forelegs.

Shining felt the urge to do the same, but something in his mind seemed to stop him, telling him that wasn’t this pony’s name.

He tried in vain to try and remember what it was, but found he could not remember.

“Come to Mommy sweetie!” Said Cadance to her diapered husband.

Shining bounded from his spot and into the pink alicorn’s forelegs.

“Mama!” he squealed in delight.

Cadance adjusted her grip around Shining and looked at him.

“Well seems Flurry did a good job showing you how to be a good little foal didn’t she? Although it looks like something is still missing.” She said as she looked over the overgrown diapered stallion before her.

Just then, her attention was drawn to Flurry as the little alicorn began to squirm and make little grunts in her arms.

“Ah yes. Looks like it’s that time. Look at your big sister Shiny!” She said.

Shining turned and looked at Flurry as she squirmed.

A few seconds later, the seat of her diaper began to droop down, and the little filly gave a little sigh before going back to babbling and cooing at her Mommy.

Shining’s mind focused on what it had just saw, Flurry messing her diapee.

She seemed rather content by the deed.

Maybe he would like messing his own diapee!

Just like Flurry, he began to close his eyes and focused on his tummy, pushing like she had.

Soon, he felt a moving sensation coming from the back of his diaper.

Pushing more rewarded him with more of this feeling, as he pushed a big load into his diaper seat.

The mush was felt warm and funny in his diapee.

He wondered what it’d be like to sit on.

He sat his but down and felt the warm mush press and spread all around his butt.

It felt good!

He bounced on his butt next to his Mommy, enjoying the mess move about around his bum.

Cadance just giggled, watching her former husband act with no modesty or reason.

“I think it’s time to get my little babies changed.” She said as she brought them both into the nursery.

After cleaning Flurry up and putting a new diaper on her, she used her magic and brought Shining onto the top of the changing table.

While she tended to his diaper, she spoke down to the big foal.

“Oh Shiny. You look just as cute as I thought you would. I was a little hesitant about turning you into a big baby, but I can see you are so much happier this way. I knew Flurry would show you how to be such a good little baby. Who knew all it took for me to have another foal was a hypnosis spell and a watch.” She said as she finished cleaning Shining’s messy hiney and wrapped him snug in new diaper.

“Alright you two, time to play again.” She said as she set Shining back down on the floor.

The two foals squealed in delight and ran out the door back to their toys, Cadance following behind them.

She was so happy to have the two best foals in the whole world.
