The Only chapter: How to plug up a Leaking Sun?

One clear and lonely night A comet falls over Equestria radiating a rainbow of colors as it hurls through the sky with a trail of rainbow trailing behind it. The object is spotted by many ponies working late, or having a nightly stroll and they all make wishes. Luna watches it from a distance ontop of Canterlot Palace but seeing nothing but a streak of rainbow light. She is a little concerned but doesn’t sense the falling star being dangerous. As everyone watches it eventually crashes down over The crystal empire with many crystal ponies gasping in surprise with awe. The object then crashes through the palace ceiling and into the nursery of Flurry Heart. Instead of crying like most foals the curious foal looked down at the rainbow rock swirling with colors and is memorized by it. She flutters down and picks it up with two hooves and giggles as it turns into a foam block with C, H, A, O, S printed on each side of the cube. Except for one blank square. The little filly giggles as she plops a hoof covered with drool on the blank space. The object shines a light as it shows now a picture of her plush snail whammy. This make Flurry really happy taking the foam cube back to her crib and snuggling it. The cube waited patiently for the little foal to be in a deep sleep and then began seeping dark energy into the innocent foal.

Seven days later...

Princess Celestia is walking through a field of a foam floor that looked a lot like a toddlers playroom or nursery. She looked to see a cartoonish smiling sun shining down onto her and whispered to herself, “where am I what’s going on?”

She then began to slowly walk back when her hoof hit something that squeaked. Celestia looked down and gasped in astonishment and saw that the room was now covered in plushies. She saw that each one was a foal plush with beady black eyes and every single one had a cloth pink mane and tail made of yarn.

As the princess looked down at the plushies guilt went through her like a wave. She clenched her chest with a hoof just as something began to whisper, look at these foals! You will never bare them! You will remain barren, alone with nobody to love you!

Celestia stepped back whimpering as the shadows grew around her enveloping the cheery nursery. Frightened but angry now the princess shouted into the pitch. “Stop in the princess of Equestria I demand you show yourself!”

She tries to hit the darkness with a blast of magic but nothing works as the spell was absorbed into the shadows. They now shrouded everything as they swirled around her like a tornado the eerie voice continued, “You will live forever like a foal in a dream while everything around you crumbles! Submit to your doubts and finally become what you were always meant to be!”

There a vision of an evil diabolical Daybreaker with her mane and tail filled with flame appeared in the shadows and Celestia in tears shouted back “I will never submit! Even if I can’t have a family doesn’t mean I don’t love the ponies rule over! Now leave me alone!” She shot a ball of energy into the darkness and then it exploded turning the shadows into a torrent of water. Before the frightened princess could move the wave hit her at full force…

Celestia gasped in fright as she woke up from her nightmare and gasps she slowly regained her composure until she looked down and squeaked in surprise as she felt something damp hitting her fur. The princess scrambled out of the bed only to see her pristine white bed sheets were now soaked in a yellow liquid and had the unmistakable pungent odor of urine. Celestia looked down at the sheets with her mouth agape trying to comprehend what just happened. Then out of nowhere her sister Luna burst through her door and looked down to see her older sister still looking down at the soaked sheets.

Like a toddler who just the wet bed Celestia whimpered, “Luna I didn’t mean to! I ..I…”

But Luna rushed over and hugged her sister close as she whispered, “it’s okay, I know I saw the nightmare. The thing is I tried to go into your dream to help but something was keeping me out.”

Celestia gave a sigh of relief feeling her sister’s embrace and gave her a wing hug back. They held the embrace for a while before Luna suggested, “let’s get you to my room and talk about some things okay?”

The older sister feeling bit patronized but was unable to think of anything to say just gave a nod as she rose up and followed her younger sister. As they walked out of the room a group of maids came in all looking groggy and a bit irritable. Celestia sighed and shook her head as she groaned, “This is the seventh time I’ve wet the bed. By this point, it’s becoming a habit that they need to clean my sheets every night. I can understand the nightmares maybe? But the bedwetting? I don’t know why this is happening.”

As they entered Luna’s chambers they both sat down on some comfortable chairs as she drifted a cup of tea over to Celestia. She grimaced taking her cup looking down at the yellow colored tea which was clearly chamomile. Luna started to sip from her cup and blushed seeing she should've given Celestia something else. But she waited patiently until Celestia was sipping her tea before she began to explain the situation. princess of the night explained, “Dear sister, I need to tell you something important.”

The princess perked up and listened in as Luna continued to explain. “You see, there is a rampant epidemic of ponies having bed wetting issues similar to what you experienced for a week now.”

Celestia blinked in surprise and asked in a concerned tone, ”a week...why didn’t you tell me about this earlier?”

Luna gave an exasperated sigh as she explained, ”at first I thought it was a few isolated instances. I was even able to help some ponies overcome it for a while...I thought I could manage but then just yesterday it was an explosion as hundreds of sheets were soaked in urine. Then with me being so busy managing the crisis. I just noticed your nightmares were becoming worse and when you wet the bed tonight...I’ve come to terms that this is something that is beyond me.”

Celestia looked down and whispered, ”does this have anything to do with the Tantabus?”

Luna shakes her head and explained, ”no it’s been banished for years now. Also, I've noticed that unlike the tantabus who wanted to escape into the real world. This nightmare’s main objective is to scare the ponies into wetting the bed. But as of now, I can’t defeat it and it’s blocking me from entering some dreams like yours. I don’t know why…”

As the two princesses pondered out of nowhere they both looked up and shouted in unison. “Discord!”

Celestia threw her cup of tea at the wall shattering it as she roared, “I knew it! He has to be behind this! This whole thing must be some stupid prank!”

Luna got up with a concerned look and commenter, “Well, it would be in Discord's nature to do something like this. But even he wouldn’t let a prank go this far…”

Celestia rolled her eyes. “You, have no idea. He can easily use chaos magic in the dream realm.”

Luna responded back. “Well at the very least he may know something about this but for now...we need to discuss the bedwetting.”

She then produced with her magic a neatly folded plastic square that was clearly a diaper along with a bottle of foal powder. Celestia’s face turned and deep red as she stammered, “well...I...um…”

Luna gave another sigh as she explained “look, I know that you haven’t worn one of these since that time you and Twilight made those foal diapers and helped me make my own brand of nighttime diapers. But, honestly I had many ponies wear one at night and things have gotten better for them. They have no nightmares and their sheets are clean, also they usually change themselves in the morning and nobody ever notices anything.”

Celestia saw it as tempting but she shook her head and sweetly responded. “Look, I really appreciate you trying to help me. But I think we should talk to Discord first…”

Luna smirked and cooed, “he’s probably asleep in his dimension, now come on stop fussing and lay down.”

Celestia stomped a hoof down and scoffed, “come on Luna, I’m a princess I..can..can't be wearing a such a foalish garment.”

Luna rolled her eyes at her sister’s attempt to be regal. “It’s made of the same material the ones you and Twilight designed. It doesn't have anything foalish designed on the fabric either. It's also perfect for absorbing night time accidents trust me I had Mrs. Paddington approve it.”

Celestia was still unsure. Yes, she has worn diapers before for fun but this feels weird like something was invading her private thoughts. She was going to say no but then turned to look out a window into the hall and saw the poor maids dragging the ruined sheats from her bed grumbling and some even giggling. Celestia ran a hoof down her face as she relented, “fine, I’ll wear diapers to sleep until this is over…”

Celestia slowly laid down onto the ground with an unsure look as Luna stood over her sister with a smug grin. She was waiting for an opportunity to do this for years slowly taking the diaper and opening it creating a symphony of crinkles. Luna then gently lifted Celestia's hind legs with her magic and slipped the diaper under her sister's rump and pulled the magical tail through. Celestia was deeply embarrassed and just watched as her sister then slowly began to place the front end of the diaper over her midriff. She sighed in relief seeing that it was just a simple white diaper with some suns printed on the plastic landing zone for the tabs. Luna then slowly strapped the tabs of the diaper onto the landing zone of the crinkling diaper and sealed them with a hoof making the diaper crinkle and pop. Celestia moaned a little as she kicked her legs a little loving the sensation.

Luna couldn’t help but smirk as she looked down and in a taunting tone asked, ”you're enjoying this aren't you?”

Celestia slowly got up and wiggled her tush as she snapped back. “Well, I could say the same to you seeing you're the one who got me to wear a diaper?”

Luna giggled as she ran a hoof down Celestia's thigh checking the yellow leak guards. The princess of the sun whimpered as her sister cooed, ”oh well, I’m not the one who wets the bed like a toddler.” Finishing her inspection by slapping the padded rump making clouds of foal powder poof from the leg holes. Celestia turned towards a mirror and admired how the diaper was designed to fit snugly around her rump. It wasn't too poofy or outrageous and the yellow leak guards looked snug around her thighs hiding the tip of her cutie mark. She stood up on her hundlegs seeing that the yellow landing zone just came a little over her waistline and did look quite adorable. But Luna wasn’t done, and Celestia squeaked in surprise as she was suddenly lifted by her sister's magic and drifted from Luna's room like a little filly's doll. Luna skipped down the hall with many guards and maids blushing to watch Luna carrying Celestia in such a way. The princess of the sun's face was now a deep red unable to even move woth her diaoered rump exposed to many of her servants. But it was only for a few moments as Celestia was soon safely back in her room. Luna came over to the bed and slid the sheets over and slowly placed her sister on the new crisp white sheets making the diaper crinkle with clouds of foal powder poofing out as Celestia hit the bed. The older sister growled but she was quickly tucked under her comforter up to her neck by Luna’s magic. With her big sister, all tucked under the deep violet covers like a school filly Luna cooed, “now if you need anything from you big sissy let me know sweetie.”

Celestia gave her sister a glare and growled, ”I swear your gonna wake up in a crib one of these d-” Before she could finish Luna plucked a pacifier with a pink mouth guard into her sister’s mouth. “Now, now no more talking its bedtime for Tia.”

Celestia growled as she was about to spit it out. But she blushed as she gave the rubber nipple a few suckles. For some reason, it was quite comforting and relaxing making her forget about the stressful nightmare she had earlier. Celestia then snuggled under the covers and slowly drifted off to sleep. Luna snickered she then turned to see an empty plug and took out a night light. It was a simple design with the bulb, shaped like a crescent moon and plugged it in next to Celestia’s bed seeing it glow a dim yellow light. She then looked over her big sister tucked in, suckling a pacifier in the dimly lit room making a crinkle sound every once in a while as she stirred and Luna whispered, “goodnight little Tia sweet dreams.” The princess of the night then slowly closed the door and with a final touch, she lit her horn and placed a sign on the handle that read. shhhh! A precious Angel is sleeping

Celestia was back in the dream nursery again But this time she saw everything was much bigger with the plushies and toys coming up to her head. The confused princess turned around and saw a mirror and there instead of a regal princess there was now a little chubby filly no older than three years old. She had, her stubby light pink mane and tail trailing out, as she also wore a huge thick diaper with smiling suns printed all over it around her rump. She just looked confused as a voice whispered, that’s a right little one. Your all snug and comfortable, now go play with your heart’s content there’s no reason to fear the night.”

Celestia goes about squealing as she jumps into a playpen filled with plush phoenix's. She then plops around for quite some time and then she blinks as she had the urge to pee. The princess looks down at her diaper seeing it was now filling up with urine with a yellow spot growing on the white fabric. The princess shrugged and chirped, “I'm a foal, it’s natural to pee in my diaper.”

The voice whispered, that's right, there's no reason to worry. Who cares if you wet the bed you're a princess…

Princess Celestia looked up to see Luna standing over her now wearing a white apron with her mane tied in a bun. Princess Celestia laid down and giggled, “but that means you have to change me!”

Princess Luna smirked as she looked down at the little Celestia and cooed, “That’s something I don't mind doing. But that diaper can hold a lot more go and play. I'll change you before the night ends.”

Celestia squealed, “Otay Luna! I'll go play!” She skips off to the plushies and hugs a stuffed phoenix as Luna watched with a smirk.

The next morning Celestia woke up with a smile having the first good night sleep in a long while. She first notices that something rubbery was still in her mouth. Celestia quickly spits out the pacifier then yawns as she got up of bed and stretched her forelegs. The princess then looked down at her diaper now soaked with a dark yellow color and sagging a little. Celestia poked the diaper making a squelching noise and gave a nod of approval as she chirped, “It worked! the diaper did its job, but tonight I'll request a thicker diaper. This one looks like it's going to burst.”

The princess then slowly got up and waddled to the bathroom with cheerful smile on her face to clean herself off before raising the sun.
