The next night, Twilight woke up and this time she was in her castle but the room she was in was rather huge with various bean bag chairs around along with other sized up baby furniture. Staring at one of the walls for a moment, she saw a poster with “Mommy knows best’ on it seeing a familiar dark purple starry mare figure smiling. “Is that the Tantabus in an apron?” She scratched her head clearly recalling she’d helped Princess Luna defeat it before? Why has it returned?
The violet unicorn took the time to look around and saw that the rest of her friends were all in cribs strapped up in thick diapers and lined up against the walls. They were all getting up and looking rather confused about where they were apparently a lot more aware of the dream than the last night’s events. Rainbow looked at her friends and said the obvious. “Uh, any clue why we are all diapered and in here?”
“It’s kind of nice,” Fluttershy said sheepishly, hugging a bunny plush that was next to her.
“Are we dreaming?” Applejack asked, looking out at Twilight. “Ya got any clues Twilight? You’re the only one not in a crib.”
Before Twilight could remark, Pinkie put her hoof up. “Did anypony else have a strange dream last night and wake up with foal items on them?”
Twilight was surprised when everypony nodded or blushed at the question. “Uh me too, and I even wore a diaper to visit my brother.”
Rainbow burst into laughter. “That must have been quite the sight for them to see.”
“T-that’s not the point,” Twilight started with her face red. “We just gotta figure out why we are having a shared dream.” She moves over the crib and tries lowering the bars jiggling them around on each. “Ugh, why won’t they budge”
“And why are you the only one not in one?” Rarity spoke up, seeming confused.
Just as Twilight tries again, the door to the room opens as the Tantabus walks in her body in a mare-like shape with an apron on. Once halfway in the room, she looked back at the door. “Come on Lulu, don’t be shy.’
They saw Luna walk in, sporting a diaper with many small crescent moons printed upon it and suckling on a pacifer. She waved a hoof. “Hewwo.”
“Luna!” All the other ponies shouted in surprise.
“Yeah, it’s me, I sowie for bringing you all into tis...I just wanted to play with some ponies as...um...an adult foal. I didn’t want others to judge me in the waking world.”
The Tantabus gave Luna a pat on the head as she explained, “oh but who better than the ponies who helped free you?” She mothered. “Besides, it seems they are enjoying it too.” The ethereal mare horn glowed as the bars of the cribs were lowered to let the group climb out.
Luna blushed as the group waddled over to her feeling like the eyes were on her. Fluttershy was the first to give her a hug. “It’s okay, you just wanted to share your um hobby.”
“So you’re not thinking I'm...weird?” Luna asked the group twitching her wings. “This is so un-princess like.”
Pinkie joined in the hug next. “Aww, you just wanted to have safety and fun. I love having fun!”
Applejack snuggled her, “my brother is into this stuff too so it ain’t too weird for me.”
“And I suppose that with the right flair that foal attire can be quite fashionable,” Rarity added, shifting her legs making her padding wag back and forth. Little diamond patterns slowly appear on it.
Luna turned around and showed off her padded rump and asked, “ya think? I like nighttime diapers but they’re hard to walk around in.”
Everypony blushed to see that the diaper had Luna’s cutie mark on the padding. Pinkie Pie just bounced over and gave the diaper a few pats, “oh Luna, stop being so embarrassed! You look so cute! Just like a young filly going to bed. All you’d need would be a sleeper.”
Rainbow poked at the big poof butt making the diaper crinkle. “Guess that means you could dream walk longer huh?” She playfully teased. “Well if you’re wearing one for real that is.”
“Yes, it does help. I have no control of my bodily functions when deep into dream walking. It’s a bit embarrassing,” Luna explained as she shook her diaper a bit more. “Besides, I think you like my pampers? You want some?”
The Tantabus smiled, reacting to Luna’s thoughts almost immediately as the purple-ish magic glowed onto each diaper butt and turned them into nighttime versions. Each big foal had its marks branded on the seats.
Twilight squeaked as she stumbled about in her thick pampers. “H...hey! How do you walk in these!”
“Hehe you don’t,” Pinkie chimed as she jumped and bumped the diapers together sending the princess toppling over.
Rainbow’s grin grew wide as she had a mischievous thought as she shouted, “diaper fight!” She then shoved her diaper right into Applejack’s face making her squeak as she toppled over.
The farm mare gasped and got up soon waddling after Rainbow and bumping into her friend to knock her over in return. “Ha take that!”
Rainbow laughed some more as she got up. “Just like my dream kind of.”
Rarity squeaked as PInkie swung her diaper into her face harmlessly knocking her off balance. She recovered quickly and smirked. “Oh, it...is..on!” With a filly-like squeal, she joined in the fun.
Fluttershy whimpered, feeling rather nervous as she waddled and then started to charge across the room and aimed her padded rump at Rainbow Dash. She jumped and sailed across the room and ended up smashing her diaper into Rainbow’s face with a light explosion of powder.
Rainbow flew backward sneezing as she did her padded rear pinballing into Luna in the process. She eventually landed in a pile with the rest of the group all joyfully laughing. with a cloud of foal powder, and crinkly pampers. When the cloud dissipated the pile of padded ponies lay there kicking their legs all with smiles as they calm down.
Helping each other up onto their hooves, they brushed off the foal powder from their manes. Twilight looked at Luna and then the nanny Tantabus. “So, I assume the Tantabus isn’t going to cause trouble like before right?”
Luna shook her head, “no...and I can have it stop padding you up in your dreams...also just to let you know I was the one who padded you up in the waking world.”
Twilight cheeks flushed red, “well I don’t mind doing this in the dream world if you ever need a playmate again.”
“I don’t mind either princess,” Fluttershy said, still sheepish but smiling.
Luna teared up as she hugged them. “Thank you!. And uh...if you want to do a padded sleepover in the waking world?”
Rarity snickered, “darling, that sounds like a great idea! I can even make the sleepers. But I most certainly will not mess myself, bleh.”
“Of course not! It’ll be just dressing up while we play games and eat junk food,” Luna squeaked.
Twilight nodded and asked, “yeah sure? So...are we diapered up in the waking world right now?”
“Um, yes...it’s just part of the dream magic that leaks out.” Luna squeaked as she squeezed the diaper between her legs. “I think it’s due to the close connection with all of you.”
“That sounds interesting...you think you could get your sister to join in?” Twilight asked with puppy dog eyes.
“Um...maybe ...she likes to diaper up sometimes, but we need to make sure she’s available,” Luna explained. “Well, I think that clears things up...do you want to do anything else before you wake up?”
Everypony shrugged and Twilight held up a hoof, “can we get tucked in?”
The Tantabus smiled. “I'd be more than happy to tuck the little darlings to bed.” She went about and tucked each pony back into their crib with a plushie tucked in their hooves and pacifiers popped in. The Tantabus watched patiently as each pony relaxed and drifted off to sleep (with the light hissing noise) The Tantabus nodded as she raised her wings and the dream slowly turned pitch black. “Goodnight my foals, I hope we shall continue these dreams for a long time.”
