The Adventure of Shining Pampers

Shining Armor was quite excited about his recent promotion to the royal guard captain and was proud of himself as he trotted across the palace courtyard. He clopped up the steps to the throne room and found it odd no pony was around. He shrugged as the letter he received before coming mentioned this was to be a private ceremony. The stallion continued his way into the middle of the throne room and was soon standing in front of both princesses of Equestria Celestia and Luna. The stallion stood there with his head held up proudly as the alicorns whispered amongst each other. The princess of the sun turned to face Shining Armor with a smile. “Hello Shining, my sister and I are very proud of your recent promotion.”

The white-coated stallion responded, bowing his head in reverence.“Thank you. I swear I will do whatever it takes to keep you two safe, even at the cost of my own life.”

Luna waved a hoof with a smirk on her face. “Oh, you don’t have to be so formal; this is just a special promotion ceremony we do for our newly appointed Captains of the Royal Guard.”

Shining Armor paused as he was looking a bit surprised at this, and not feeling prepared; he squeaked, “I am pleased to be acknowledged in such a manner, and I'm quite grateful.”

Celestia bent down to the stallion’s level and responded in a soft, almost motherly tone. “Hey, don’t worry about it, now close your eyes; this is going to be quick ok?”

Shining gulped and gave a small nod, still being unsure of this whole situation but did as was told and closed his eyes shut; a magical “poof” exploded around his rump. Shining didn’t feel different, but something was off...he sniffed the air and smelt something sweet and powdery, making him sneeze. The stallion also felt something strapped to his rump; it felt like a massive pillow that encompassed his thighs and making his legs spread out. Shining Armor started to quiver, having an idea of what the princesses just placed on his rump. He then slowly opened his eyes and wanted to ask the princesses what was going on; as he stood there, Celestia bent down to Shining Armor’s level and stared right into his pupils. Shining seemed unable to look away as Celestia's eyes began to swirl as the princess cooed. “Now hold still Shiny, this will only take a second...”

As Shining’s eyes were now swirling and were clearly now in a trance, Celestia took a trot around the stallion’s rump and lit her horn. She used her magic to tug at the padded material around the stallion’s rump, making sure it was snug tight as she explained to her sister. “this new diaper material is so much better than what you saw a thousand years ago; I even enchanted his padding to expand in size.”

“Oh, let me see!” Luna’s voice cried out and trotted around to her sister’s side. Celestia smirked as she lit her horn once again and sent magic right at the padding and soon the massive diaper. Shining Armor squeaked as the diaper between his legs started to expand and ballooned around him, lifting his entire body off the ground.

The stallion was now sitting on top of his humongous diaper and couldn’t move from the spot. He shifted about, unable to move with only making a crinkling sound echoing around the room and poofing out what had to be foal powder from the leg holes.

“Oh, he’s trying to see his padding; let him see what he’s wearing,” Luna suggested with a growing smirk on her face.

Celestia then turned the podium with Shining Armor turned to face a mirror to see his reflection with the biggest diaper he’s ever seen strapped over his rump. It was quite enormous with the padding towering over his rump with it being a giant crinkling mass with little swords and shields and alphabet blocks printed on the padded material. The stallion was still under a trance; however, Celestia turned towards him as she lit her horn and explained, “now stay still and pay attention to me.”

The stallion stared into the princess of the sun’s eyes as Luna whispered into her sister's ear. “Oh, it’s been far too long since we’ve done this together. Can I do the explaining?”

The princess of the sun snickered, “sure.”

Luna looked straight into Shining’s eyes and explained. “Since we became the princesses of Equestria, we have initiated the newly appointed Captain of the Royal Guard like they were our foals and have treated them as such. Now, this is a secret, and as such, you will only like wearing your diapers and act foalish when we say the words Poofy Bottom. Until such time you will have no recollection of these moments and only think back on these sessions as odd dreams.”

Shining tried to fight back, grunting, and trying to avoid Luna’s gaze. But he slowly and surely the princess of the night had him under her spell as he soon was unable to take his gaze off her as the stallion was now completely hypnotized by the princess's magic. The princess of the night continued, “now, while in these sessions, your new name will be Shining Pampers.”

Shining wanted to cry out that wasn’t his name but instead, he mumbled. “My name is Shining Pampers!”

“That’s right, and as Shining Pampers, you love wearing thick diapers around your rump, right?” Luna asked, and the stallion wanted to shout no! But he was unable to resist as drool came out of his mouth and mumbled, “yes, I wuv tick diapees.”

Celestia couldn't but give Shining a motherly smile and dawwed, “oh my, that was quick; the last captain took about day before he gave in.”

Luna nuzzled Shining and kissed his muzzle as she cooed, “oh, I missed doing this; I want to have more sessions with him, seeing you’ve had a thousand years of captains to baby without me.”

“Fine, you can baby him all you want, sister. I owe you that much,” Celestia mumbled reluctantly as she turned to the diaper and continued to poke and prod the padding with a hoof and continued to explain to her sister. “I forgot to mention this diaper is special; it's designed to be the ultimate protection for royalty just in case we are attacked during our babying sessions.”

The stallion was feeling more comfortable kicking his massive pampers and seemingly trying to walk despite his body now lifted a few feet in the air.

Luna couldn’t help but turn to her sister and ask, “let’s test it out and see if you got scammed!"

“Oh yes, that is a good idea, sister!” Celestia chirped, getting excited herself. She got in front of Shining’s face while Luna moved around the back. The stallion blushed as he looked into the white-coated alicorn’s face lighting her horn. “Ok, sister, try it out!"

The princess of the night lit her horn as arrows and spears were thrown onto the padding. The massive diaper did its job as the projectiles bounced off the padding with a few thumps and clattered on the ground below.

Celestia turned to her sister with a smile and exclaimed, “See, told you! This diaper is quite durable!”

“Oh, I’m not done yet!” The princess of the night proclaimed as she started to shoot beams of magic, making Shining Armor cry out as the bolts bounced of his padding having it sent out a poof out a massive cloud of foal powder. However, the stallion couldn’t help but kick his legs, giggling, and cried out, “do tat again; it was fun!”

Luna couldn’t help but daww as she trotted around him, then plopped a pacifier into his mouth and cooed, “Alright, here’s test number three, cutie.”

The princess of the night lit her horn deflated the diaper so Shining could walk on all fours. Luna then took out a container of foal powder, lifted Shining into her magic, lifted the front of his diaper, and poured the entire bottle down his rump. The stallion kicked and coughed from the powder puffed outwards as he snapped, "ugh, why ya do tat?"

"Oh, just in case if you have an accident, cutie," Luna snickered as she walked down towards the end of the hall. When the princess of the night then teleported some armor suits on either side of the hall and exclaimed, "now come on, Shining waddle towards me!"

Shining put on a confident face as he began to toddle down the polished stone. The diaper was quite cumbersome, with him having some trouble getting used to the added weight and the added puffs of foal powder making him sneeze. All the while, the enchanted suits of armor would poke and prod his padding with their weapons. But he seemed unphased even when he started to pee into his diaper with an audible hiss that echoed throughout the grand hall. The padded stallion didn't care, giggling and cooing as he toddled down the hall, shaking his padded rump about without a care in the world. He eventually reached Luna and raised his forehooves showing his soaked yellow-stained diaper front with the prints fading as he spat his pacifier out and squealed, "I did it, Lulu!"

Overwhelmed by maternal emotions, Luna couldn't help but squeal in delight and nuzzled. "that's our Shiny Pampers; oh, you're just so adorable!"

The princess of the night then lit her horn, and Shining's diaper inflated to its massive size once again as Luna smirked. "alright, I'll change your soggy butt after one last test!"

She shot a beam of fire and slammed it at Shining’s rump, but it did nothing to the diaper as the smoke and flames sizzled on the padding. The stallion blushed to feel his diaper warming up around his flanks and not just because of the fireball hitting his diaper. Shining cheeks flushed red as he was starting to pee into the thick padding that continued to expand between his legs. He continued to flood his pampers with urine until the prints in the back of his diaper began to disappear. Luna was the first to notice and couldn’t help but laugh. “Oh, Shining’s having another accident already.”

Celestia quickly came around the stallion's rump with the prints fading and the padding yellowing and got a good view of his padding and dawwed, “oh my, he must have been holding it in for quite some time, huh Shining?”

“Y...yeah I...I was too nervous about going potty earlier.” The stallion babbled under his breath, feeling embarrassed at what he just said.

“Awww,” Both princesses cooed as Celestia lit her horn. Soon the massive diaper started to fold into itself, making the stallion squeaks as he plopped onto a much smaller version of his soggy pampers, making the padding crinkle and poof some foal powder out from the leg holes making the princesses daww again. The princess of the sun rubbed his soggy diaper and snickered, “he’s still so squeamish it might take some time for him to get used to this.”

Shining just laid down and spread his legs out, getting ready for a diaper change as Luna came over with some foal wipes and exclaimed, “not so fast, sister! I shall do the first diaper change!”

“Ok, then I’ll be the first to feed him!” Celestia scoffed, getting a bit irritated, not being able to baby Shining herself. The older mare moved out of the way as she took out a giant foal bottle full of warm milk and shoved it into Shining’s mouth as Luna unstrapped the padding around the stallion’s rump and did a good job of wiping his rump down. As his rump was cleaned, Shining suckled the warm creamy milk down his throat as he looked up aimlessly at the ceiling. As soon as his rump was cleaned, Luna peered over his head and whispered. “Now, I'm going to clop my hooves. When you hear this sound." The princess then clapped her hooves together then continued, "You'll be our strong, handsome grownup Shining Armor again, ok?”

Shining Pampers didn’t understand what the princess was talking about and simply nodded slowly as Luna clopped her hooves together, and the stallion's vision suddenly went black.

An hour later...

Shining Armor blinked as he was now outside of the palace; he looked down at his armor, still looking polished and clean. He then turned to look back at his rump and seeing nothing but his cutie mark and scratched his head. The ceremony was over, and from his vague memories, the princesses just wanted to congratulate him on his accomplishment personally. But something was off...He sniffed the air smelling something sweet and powdery, and before the ceremony, he had to pee really bad, and now he felt quite relieved. Shining paused, pondering what happened in the past few hours, and eventually shrugged as he whispered to himself. “It doesn’t matter. I probably slipped off to the bathroom real fast and forgot...and I think that smell is my shampoo...I’m just gonna go to the nearest bar and get drunk.”

Shining quickly walked off, not worrying about something as silly as when he used the bathroom.
