Celestia and Luna both woke up in their cribs in their soggy pampers after their nap. They both looked at each other with tired and grumpy expressions on their faces. Celestia slowly raised herself using the bars of her crib, revealing her adorable diaper slightly yellowed as she turned to her sister and yawned. “Hey, ya wana go see whewe Fancy Pants is? I bet he sweepin with Nana Twiwy.”
Luna also nodded in agreement as she babbled. “Yeah, it not faiw tat he gets to sweep with hew! She ouw nana fiwst!” They both flew over the cribs and waddled off down the hall shaking their thick, soggy pampers back and forth. The two headed straight towards Twilight’s bedroom and squeezed through the door which had been left open slightly ajar.
both looked up to see Twilight Sparkle lying in the bed with Fancy Pants nuzzled into her underbelly, the foal suckling onto her teat, seeming to be so happy and peaceful. The two princesses both got even more jealous seeing that Fancy Pants getting to sleep with Nanny Twily and drink her milk.
Celestia crossed her hooves and bounced on her padding, making it squish between her legs as she babbled quite angrily. “Is not faiw, he gets to sweep with Nanny Twiwy and we dun.”
Luna nodded in agreement as her tummy grumbled and she gave it a few pats. “Yeah, I hungwy and want Nana Twiwy’s miwkies.”
The two foals both fluttered onto the bed and waddled over to Fancy Pants, who turned his attention to the baby alicorns. The stallion got up on his soggy pampers too, making them squish beneath his rump. Eyeing the princesses he babbled. “What ya twi doing?”
Celestia crossed her hooves with a pout on her face as she grumbled. “Ya not gonna have Nana Twiwy to yasewf, tat not faiw.”
“Yeah, ya gotta shawe hew, is not faiw ya gets to sweep with hew!” Luna shouted at Fancy Pants in anger.
Fancy Pants rolled his eyes and babbled. “I not hoggin’ Mama. I tink tat ya two just jeawous and ya wants to buwwy me. But I dun cawe.”
Celestia blushed as her tummy grumbled and she scoffed. “Nuh uh, we not gonna buwwy a. We just want Nana Twiwy’s miwkies. We hungwy and she sweeping too wong!”
Luna was getting quite flustered as she shouted. “Yeah, ya bettew not have dawnk awe hew miwk!”
Fancy Pants got up and whined. “I didn’t! Go ahead and dwink Twiwy’s miwkies. She neva wuns out.”
The two princesses slowly came up to the big alicorn, and each of the baby alicorns took ahold of one the teats of Twilight and the two slowly began to suckle her milk. The mare squeaked as she felt the sudden jolt of the foals suckling milk from her, which roused her from her sleep. Still she turned to see the two babies with a soft smile and dawwed. “Aww, someponies are hungry. That’s so cute. Go ahead and drink up, there’s plenty of milk for both of you.”
The newly created alicorn then laid back down, humming as she fed her charges while she took out her book and started to read it. The mare then turned her attention to Fancy Pants who sat there with a pout and had crossed his hooves. Twilight blushed and asked him. “Did you get enough to drink too, little Fancy Pants?”
The little colt nodded and looked up as he babbled. “Yeah, I did. Tey needed miwkies too so I otay.”
Twilight sighed having a feeling that the fillies forced the little colt off and asked. “Let me guess, they kicked you off?”
Fancy Pants grumbled. “Yeah tey did, tey jeawaous tat I swept with ya wast night,” Twilight just chuckled as she levitated Fancy Pants in the air and hugged him in her hooves. He rubbed his hooves over the mare’s face as he babbled. “Ya a good mama. I wove ya.”
The mare then gave his soggy pampers a few pats and giggled. “Oh my, you’re so soggy. I guess I should change your diaper before you get a rash,” She went about changing the colt’s diaper and mmmphed feeling the little fillies suckling on her teats quite roughly. “Hey, go slower.” She mumbled.
The two fillies did as Twilight asked suckling the milk quite slower while the mare continued to finish Fancy Pants’s change. She took off his diaper and went about wiping his rump clean. She then went about giving his rump a good showering of foal powder, and finished the change by strapping the colt into a new, fancy looking, light blue colored diaper.
Afterwards, Twilight took the baby princesses and went about changing each of their diapers as well as she commented. “You foals are quite heavy wetters, I might have to tape you all up in double padding at this rate. Can’t risk having you leak through and wet the bed.”
The two regressed princesses blushed, quite embarrassed at being called heavy wetters as Twilight finished up the diaper changes for them. After the double change she went about taking the fillies over her shoulder, patting them on the back and thus having them spit up. After cleaning up from that, she placed them down and got a bit stern as she asked them. “Now Celestia and Luna, were you two being mean to Fancy Pants earlier?” The foals both blushed as they looked in shame. With a harsh glare Twilight scolded. “Fancy Pants is younger than you two, so that means he is your younger brother. You two need to be nice to him. Is that clear?”
The two princesses both slowly nodded and mumbled. “Yes, Nana Twiwy We sowwy.”
The mare then levitated the foals onto her back and then placed them in a playpen as she cooed. “Now there’s a lot I have to do today so I need you three to be on your best behavior. Alright?”
The foals all nodded as they babbled. “Yes nana Twily.” Twilight then went to a couch she had set up in the courtroom which was now a glorified nursery and play area filled with foal toys, plushies, and a playpen with a pink fence surrounding the area.
Not long after being placed in the playpen, Celestia waddled over to Fancy Pants, who was busy playing with foam blocks, and asked him. “So Fancy Pants, ya wana weawn how ta use ta potty again?”
The stallion smacked the blocks in excitement and went about bouncing on his pampers, poofing out big poofs of foal powder as he exclaimed! ”Yeah! I dun wan be cawwed Fancy Diapee ow Diapee Pants any mowe! Whewe’s ta neawest potty?”
Luna waddled over and babbled. “I tink tat we can use one of owa toiwets tat used ta be owa thwones.”
Fancy Pants giggled putting his hooves to his face as he babbled. “Tey stiww awe, tey ta pocewin thwones!”
The two fillies burst into laughter, rolling around on the ground at the joke. Fancy Pants rolled his eyes and looked over at Twilight, who was going about writing reports and appeared to be unaware of the foals plans. The colt tapped a hoof to his chin and bounced on his diaper making foal powder poofed out as he babbled. “I guess we gotta do it whiwe Twiwy is busy, but we might get in big twoubwe when she notices we gone.”
Celestia waved a hoof. “Nah uh, ya gonna be fine! Now come on, wets go! Ta soonew ya get potty twained, ta fastew ya gonna be outa diapees!”
Fancy Pants was hoisted over the playpen and he and the regressed alicorns waddled past an uanware Twilight. Fancy Pants was led down the hall to the throne room where the pink and purple colored toilets stood. The colt got quite nervous looking up at the toilets, noticing that one had Celestia's cutie mark on it while the other had Luna's. They were quite big compared to the foal and he was starting to get scared. What if he fell in?
Just then, Fancy Pants heard strange gurgling noises from the toilets and he started to smack his thighs against his padding as he asked. "C...Cewestia wha is tat noise?"
The princess of the sun snickered behind a hoof. "Oh, is just ta potty monstew. I heawd tat he wuvs to eat foaws tat dun know how to use ta potty. But ya gonna be fine, ya got us to pwotect ya," Then she instructed. “Now come on, take ya diapee and we hewp ya get on big potty. Ya can use mine.”
Then, suddenly and without warning, the top of Luna's toilet slowly opened up! It revealed rows of sharp teeth on the bottom of the lid, which now looked like a mouth. Celestia’s eyes went wide eyed and she squeaked out in fright! “Oh my me! Tats ta potty monstew, wun!"
The toilet reared up, snapping at the foals before slamming the lid and smashing it against the seat as toilet water spouted outwards. Celestia gulped as she scrunched her padding between her legs to avoid getting splashed, and she babbled. "Uh… Wuna, ya can stop now!"
Luna waddled over, scratching her head. "Wha ya tawkin about? Me not do anythin." She also looked up and gasped upon seeing the toilet as it roared, spouting out more water outwards as it began bouncing towards the foals! They all ran off as fast as they could from the potty monster!
They ran back toward Twilight as fast as they could, all the while the giant toilet kept slamming the lid and shouting in a scratchy voice! "I'm gonna eat you! Foals are my favorite meal!"
The foals screamed in fright while waddling away in their crinkling diapers! Soon they slammed right into Twilight’s lap, making her squeak in surprise. She looked down at the foals and asked in confusion. “Huh? What’s going on?!”
Fancy Pants raised his hooves, showing off his adorable padding as he babbled. “Nana ta potty monstew is coming! Ya gotta save us!”
Celestia turned to Twilight and was bouncing in her padding on Twilight’s lap as she cried out. “Yeah! Wuna and I wewe pawying a pwank on Fancy Pants, but ta potty is actuawwy awive!”
Twilight looked up and saw the toilet monster snapping its jaws. It made her roll her eyes and grumbled, “Discord seriously!?”
The dracquinous then suddenly appeared in a puff of smoke with him laughing. “Sorry, I just couldn’t help myself when the princesses set up that little prank for Fancy Pants. Decorating the toilet to look like a foal eating monster, hilarious!” He quickly snapped a paw, and the toilet returned to normal and teleported away. “There, I put that ‘throne’ back where it belongs. You’re welcome. But you’re not getting anymore favors from me.”
Twilight eyes glared at the baby alicorns. “Seriously?! I can’t believe that you would do that to Fancy Pants! What, were you going to try and flush him too?!”
The two alicorns looked down, feeling quite guilty and they both started crying. “We sowie, Twiwy. We wewen’t gonna fwush him, honest. We wanted him ta get out of diapees, bu we wanted to have a wittwe fun with him fiwst.”
Fancy Pants blushed as he waddled over, making his adorable diaper shake about as he hugged the little fillies, nuzzling them as he exclaimed. “I not mad at ya! Tat was a funny pwank, ya two! Ya wucky ya got ya own, custom big potties instead of bowing, owd white ones,” Then he looked up at Twilight with puppy dog eyes and whimpered. “Hey Twiwy, dun punish tem. Tey just twying to hewp me. I ta one who wanted to use ta potty.”
Twilight dawwed before she rubbed a hoof across her mane and sighed. “Alright, I guess I can let it slide. But you two better stop being mean to Fancy Pants. And please don’t ever go near those toilets or any others without me, I don’t wanna take any chances that something could go wrong!”
Celestia and Luna both blushed and slowly nodded their heads as Discord shrugged. “Guess that means my work is done here. Until we meet again, princess.” He then snapped a claw and disappeared in a puff of smoke.
Fancy Pants waddled over with a blush on his face, his diaper squishing between his legs as he asked. “So uh...Nana, I peed my diapee, can ya change me?” He poked his padding, making an audible squishing sound.
Twilight dawwed again as she picked him up and nuzzled him. “Oh, you’re just so adorable! Of course I’ll change you, Diaper Pants.” She then went about changing his soggy diaper.
After the diaper change, and after a few hours of playtime (and a dinner of Mashed Peas). Twilight took the three foals upstairs and was surprised to see there was a new crib in the princess alicorns’ nursery. Not only that, there was also a closet filled with diapers folded up nicely on top of each other, and a bunch of cute onesies all hung up inside. The princess alicorn giggled. “Oh, that's just too cute! Looks like Discord has your crib all set up, Diaper Pants.”
The mare then settled each foal into their respective crib and slowly tucked each one in under a bunch of foal blankets as she cooed. “Now you all get some sleep and don’t stay up all night, okay?” Twilight then slowly left the room.
As soon as Twilight was gone though, both Celetia and Luna teleported themselves to Fancy Pants’ crib. He squeaked and kicked about as the fillies snuggled the colt on both sides, wrapping their wings over him as he blushed, feeling quite odd about this. He babbled. “Wh..why ya doing tis?”
Celestia nuzzled him and cooed. “We sowie fow aw ta twoubwe we caused ya today.”
Luna nodded and babbled. “Yeah, ya owa wittwe bwuda and we did tweat ya badwy aww day. We pwomice we gonna take cawe of ya fwom now on.”
Fancy Pants blushed as he responded. “Wook, I tink ya two awe funny but how ya gonna cawe fow me? Nana Twily awweady wiww.” But then he squeaked as they went about changing his diaper again, and taping him into two thick, nighttime diapers.
Celestia babbled. “We gonna take cawe of ya when Nana Twiwy can’t.”
Fancy Pants blushed as they nuzzled him and placed their wings over him. “Is gonna be wewid, I was a onwy chiwd as a foaw. I wondew wha having two big sissies wiww be wike?”
