It was a place of nightmares and of terror. It was a twisted world like no other. Blood red grass covered the ground as a swirling sky of a million eyes loomed overhead. And in the center of it all, a young sandy brown filly cowered in fear.

The young pony could feel each and every eye burning their gaze into her head. She couldn’t flee, too terrified of the very grass she attempted to walk on. She was paralyzed with fear, struggling to find solace in a world so scary.

“You can do it, young one. Just remember what I told you,” a voice echoed in her ears, even as the whirling winds of a thousand laughs overpowered her senses and bore down on her. She desperately tried to steady her breaths and heed the voice’s advice.

And finally, everything seemed to click.

In one gigantic wave the nightmarish environment reverted to normality. Eerie, gnarled trees transformed into happy trees covered in flowers. The red grass, with tips as sharp as knives morphed back into soft bluish-green fields that were just perfect for sleeping on. The sky, once a black and red swirl of a million eyes turned into a tranquil sky with little cheerful birds chirping away as they fluttered across its blue expanse.

Princess Luna smiled at the change as she stood atop a soft sloping hill that overlooked the lovely landscape. She proudly smiled down at the small, sandy brown earth filly who gazed upon the trees and fields with awe.

“You see? Our nightmares might seem scary, but they do not control us,” Luna consoled the filly, “it is perfectly normal to be worried about performing in front of groups, but remember that our fears make things seem scarier than they actually are.”

The young filly continued to stare across the horizon, listening to every helpful word her princess had to say. “You really think I can do it?” she asked with a quiet voice.

Luna smiled a comforting smile as she lowered her head to match the filly’s eye level. “My child, you are still young and there is much to learn. You are capable of so many great things.”

The young earth pony swooped in and gave Princess Luna a big hug, “thank you, princess. Thank you so much.”

Luna hugged the other pony back. “Best of luck to you, young one,” she said as she squeezed the filly tight before steadily standing back up. “Fare thee well,” she said with dignified poise before stretching out her wings and flying up into the sky, eventually phasing through it like a blue curtain.

A deep blue and purple expanse stretched out before her as the bright vibrant colors of the filly’s dream faded behind her. It was in this endless space that dreams were made and it was Princess Luna’s responsibility to ensure each dream was a peaceful one. The dreams materialized themselves as shapeless bubbles, shimmering in the moonless light of the dreamworld’s beautiful void.

On most nights, Princess Luna spent her time floating amongst the dreamspheres. Her time dreamwalking was usually pretty uneventful. Sure there was the rare nightmare to defend against, but those were incredibly uncommon and far inbetween. She had a lot of time to herself floating here, dwelling on wayward thoughts, fantasies, maybe even doing a math problem or two if she was incredibly bored.

Although on some rare nights, Luna engaged in a rather deviant hobby of hers. Luna would pass the time with finding ponies who were having sex dreams and giving them a little watch. It was not out of malice or ill will, but rather out of entertainment. To peer into ponies’s more intimate dreams was a delightful affair of discovery and surprise.

She never interfere in these dreams of course. She was naturally invisible to the dreaming ponies and her presence was never made known unless she allowed it. She found it much more enjoyable to just watch the scenes play out rather than trying to persuade and alter the dreaming pony’s scene to better fit her own desires.

Seeing how quiet tonight had been, it seemed like the perfect night for some dream voyeuring.

Sex dreams were easy to find for the experienced dreamwalker. All she had to do was feel around for them. All dreams of sexual tendencies or tabooish in nature gave off a very distinct sensation. Not a sensation of sight or sound, more of a mental sensation. It was an unmistakable aura she felt around dreamspheres, the energy given off by such lewdish thoughts as a sex dream.

She didn’t have to travel far to find a dreamsphere that gave off that particular sexual aura. After floating through the dreamscape, Luna stumbled across just what she was looking for. A dream conjured up by Big Macintosh no less. Driven by excitement and enticed by what such a quiet stallion dreamed of, Luna dove right into the dreamsphere, entering the world that the slumbering Macintosh had dreamed up.

She entered a dimly lit room, lit up only by the closed window across the way. A calming blue sunlight of an early morning sun filtered through drawn curtains, hinting to the upcoming day. The room seemed, strangely enough, feminine in color scheme, utilizing brilliant shades of pinks and purples to decorate its furnishings. As Luna floated there, hovering above the scene to let her eyes adjust to the dim light, she realized it resembled some sort of foal nursery.

The nursery came well equipped with all the usual dressings, only they were made much larger to accommodate full grown ponies. The changing table alone made this more apparent with its wide padded top and extra large diapers. The toy chest and dresser across the way surely contained enlarged versions of their foalish counterparts. Even the crib, propped up against the far wall, dressed up in flowery printed bedsheets and crib bumpers resembled a full sized bed in its sheer size.

What struck Luna the most surprised was the amount of detail put into the very objects in the scene. Such structure and design was put into each furnishing she found in the room, a mark of a pony who had spent months, maybe even years obsessing over such a scene. This was no spur-of-the-moment, passing fantasy. That was made very apparent to the observant princess.

Macintosh was found lying in the large crib soundly asleep. His head rested upon a plush, bright pink pillow as his body laid cloaked in a wispy, nearly transparent, white blanket. A pink bow tied itself loosely around his neck while a pink pacifier bobbed idly in his mouth. A pair of pink striped stockings laced up his back hooves, adding to his girlish look. And as the piece of résistance, a green and white diaper with colorful apples printed across its surface was taped securely around his waist.

It was certainly a strange getup to see the burly stallion dressed up in. From the brief encounters Luna had with Big Macintosh in the waking world, she could at least draw that he was a hardworking and diligent pony. But perhaps he had some sort of repressed childhood or a longing for a more innocent time. Certainly didn’t explain why he was a full grown stallion in this dream, but it did explain the nursery setting.

“But I still don’t understand,” Luna muttered to herself, “the aura of the dream suggested it was...”

As if setting up a new scene, the drawn window curtains magically pulled themselves open, tying themselves off on either side of the window. A late morning light now shined through the window as a peaceful wooded forest could be seen stretching outside.

Macintosh now stirred from his slumber, lazily kicking the blanket off his body to expose his entire girlish outfit to the dawning sunlight. Instead of being surprised by the clothes, the stallion sleepily smiled and even gave his pink pacifier a couple happy suckles. His hoof dove downwards to investigate the thick diaper, giving it a few pats as if to mentally conclude that he was diapered.

Without getting up, and in full view of Princess Luna, Macintosh began soaking his diaper, filling it up with a powerful stream of urine. A deep yellow surged up the green and white diaper, swelling its absorbent insides in an instant. The diaper barely even flinched, and soaked up the urine without a single leaked drop. In one fell swoop, the diaper filled up full with urine and sagged heavily with its immense, wet weight.

Barely a sigh of satisfaction had time to leave Macintosh’s muzzle before his penis became rock hard underneath the hefty weight of the urine soaked diaper. He shamelessly reached for the throbbing bulge in his diaper, and immediately gripped it hard between eager hooves.

He moaned loudly behind his pink pacifier as he groped and molded the warm, swollen bulk that his diaper had become. All the while he squirmed and wiggled in his crib, kicking aside any wayward blankets and pillows. He was positively ecstatic by the wonderful sensations of pleasure that coursed through is body.

Before he could get to far with his groping session, however, his sister Applejack entered the scene. Much like the stallion, she appeared completely unchanged from her waking world counterpart. Although she appeared to have a softer and caring expression on her face. One a caring mother would be expected to have. She didn’t bat an eye at the groping stallion and just smiled at him like one would to a slumbering child.

“Well look who’s up!” the dream Applejack cooed, “didja have a nice nap, lil’ Mack?”

Macintosh nodded with a childish giggle, momentarily resembling a pony half his age. He continued to feel up his throbbing member through his wet diaper, even as Applejack lowered the crib’s side gate.

“Well ah hope yer hungry,” Applejack continued to coo, “it’s time for breakfast!”

Effortlessly, Applejack lifted Big Macintosh out of the crib. The much larger stallion appeared weightless in her arms, hardly weighing more than an actual foal. He was carried over to the nearby changing table where Applejack wasted no time in changing his diaper. Once the diaper was opened up, Macintosh’s throbbing hard-on shot up straight into the air, immediately drawing attention to it.

“Now ah know you want yer big sis to help ya with that,” Applejack said, brushing Macintosh’s throbbing member with a poke of her hoof, “but before we kin have our fun ah want you to get full use outta this diaper, alright? Fill it up good and big sis’ll help ya out.”

Macintosh just nodded, grinning goofily at his sister. He grew excited at the lewdish promise. All he had to do was fill his diapers and Applejack would help him. He didn’t have to worry himself with alternatives. That promise was all he focused on.

The new diaper was effortlessly taped on tight and secure around the stallion’s waist, undeterred by the large throbbing cock that would otherwise interfere with a snug fit. His penis still begged for attention underneath all that padding, but his gullible, dreaming mind told it to wait. All he had to do was fill his diaper up and Applejack would help him.

“Let’s go git some num nums,” the dream Applejack cooed as she once again picked up the stallion into her arms. Idly patting her ‘little brother’ on the back, the mare carried Macintosh out of the room, leaving a rather puzzled Princess Luna behind.

Luna continued to float over the scene, wearing a confused look on her face. It was tough to make sense of such a strange dream. It was clear that Big Macintosh found the whole diaper thing sexually arousing, but it was certainly nothing that Luna could get behind as far as entertainment was concerned. Still her curiosity was peaked.

She knew she should have just left at that point, but her curiosity got the best of her and she stayed longer inside the dream. She was put off by such an unorthodox dream, but wanted to see how far it went. She wanted to see just how much Macintosh had planned out. And so, against logical reasoning and common decency, Luna floated along and followed the two earth ponies downstairs into the kitchen.

Author's Note

Let this story be a good lesson for all you writers out there. Never throw out unfinished pieces. This story started out as a passing thought. It was a fragmented concept I had on my writing desk for awhile. For the longest time it was just “Luna enters Macintosh’s dream where he’s wearing pink and a wet diaper. She also finds herself in a diaper and can’t escape.” I didn’t have any of the details ironed out and there was much of the story aside from a few broken paragraphs. It was until recently that I finally got the inspiration and the drive to finally add onto it. That handful of paragraphs grew into a sizable story that I enjoyed writing!

Also, wow, I really write a lot about Big Macintosh. He seems to accidentally slip into a lot of what I'm writing right now. This is likely because I want to write about male characters and there are already slim pickin's when it comes to male characters and Macintosh is just an unfortunate first choice when it comes to that. But I assure you this is mostly accidental and stories in the future will start to steer away from the big red guy as time goes on.

For now I hope you enjoy the story. Above most things I hope that these stories are enjoyed. I like to write these stories on the side and it feels good to share them with others who can enjoy them as well!
