A Commission Lulu Dirtied a Diaper
Lulu has been transformed into a cute little baby. She doesn't like the high chair, the diapers, everything. She is still a massive baby and a jerk. She needs to be further put in her place...Always open for commissions. Email or discord me. Check profile for further information. Newsletter with free goodies open. No spam - ever.
The high chair was abnormally high for a little filly, Luna. For a normal filly, this would be just another day, filled with all the woo and wonders of the new experience called life. But Luna was not a filly, not originally, not really. She'd been transformed, 'accidentally', into one. She hadn't seen such a distance between her and the ground for some time and so it loomed like dread.
Luna was snug and secure though, her little hooves kicking idly as she casually nursed on the rubber tip of a bottle. A very condescending and smug look etched into her face as she watched Celestia telekinetically cleaning up an 'accidentally' fallen sippy cup. It was impressive that Luna could seem so regal given she was in a diaper, a baby bib, and some of the sippy cup's contents managed to coat her diaper.
"So, how is that reversal spell going?" For if Luna was no longer imprisoned and doomed to this small, yet adorable form, this would never even be an issue.
Celestia enjoyed that Luna was no longer a pain in the ass pony, but just an unruly filly, but that didn't mean that she necessarily enjoyed either or. One just had more perks. But in moments like this, Celestia just didn't enjoy all that overly much.
The towel smeared the floor this way and that.
With a bottle in hoof, Luna used the other to stretch out and point in the general direction of the mess, offering no real help other than to aggravate her friend and now caregiver, "You missed a spot." She punctuated her bratty works with a nice wet suckle on that rubber tip of her bottle.
Celestia was annoyed, obviously, but underneath it all she had a thin tight smirk of her own, it only grew as Lulu slurped on the bottle even more. What the haughty filly, who had grown too comfortable for her breeches, didn't know was the bottle had a little extra something to get the belly rumbling.
And after the suckling, the effect was nearly immediate. The belly rumbled and grumbled. Luna's face twisted and screwed into discomfort, but she was a trouper and tried to hide it, contain it, but it was just too much for her and it was easy to see that something was going to have to give.
Celestia finished cleaning the sippy cup and turned her attention to her wonderfully transformed little, now baby, sister and in the most sickly sweet voice that would rot teeth, she issued her own condescending inquiries, "Awww, does little Lulu's tummy hurt?"
"Luna..." Luna whimpered, her blue face beaming bright crimson with strain and shame, and embarrassment. Her stomach was roaring and grumbling in a distinctly non-princess way. She hated that little pet name that her sister gave her and she'd be damned if she would forego the opportunity to admonish and correct her sister, even at this rather inopportune time.
"What's that little Lulu? I didn't hear you. Your belly is making an awfully loud rumbling." Celestia teased.
"You did this!" Luna managed to say. Her rage and anger and shame came out quickly and as she spoke the accusation, a loud slushy mushy sound could be heard. She shat herself. It landed right into that frilly, filly, fluffy, white diaper. The bottoms exploded wide. And thick. The sound of it was music to Celestia's ears. The sound of it to Luna was, well, humiliating to say the least.
"Oh, Lulu, I have no idea what you are talking about." The sister said surprised. Incredulous. A toying inflection that revealed the sinister truth in the sweetest and most adorable way possible. A rich and soft chuckle emanated from her throat and mouth, not the rolling kind of chuckle that originated in the belly. It was a front, a way to really drive home the humiliation that Lulu was experiencing, "But, it smells like one little foal needs a change."
Luna would have retorted with as much spite as she could muster, but she was too busy stewing in her sloppy excretion to manage even that. Not to mention that a new helping of belly rumblings waved through her body with such ferocity that what was going to happen was a foregone conclusion and nothing was going to stop it. And Luna knew it. And she felt the shame of it even before it happened.
But it did happen, the full diaper became much full. Excessively full.
The smell was hideous, like spoiled, rotten, detestable garbage. The kind that was taken out into the alley and left to marinate. But it was more than just that, there was an aroma that was particularly sulfurous, pungent, and overwhelming. It was bitter, it was sour, and it was immediately offensive.
The diaper wrapped around the groin of Luna equally puffed out as the contents of her belly spilled and filled the back of the diaper, but it had nowhere to go except in the front. Her diaper wasn't just full, it was overly full, to the brim, almost... but not quite to spill over through the snug waistband of the diaper itself.
"Well, looks like I just got to clean you up."
"You most certainly will not!" Luna complained. As if this humiliation wasn't enough, she was damned if she was going to fulfill all expectations of a baby. She might look like one, frankly act like one, but she was absolutely and without a doubt not a baby. At all.
"Well, does a little baby Lulu want to just sit in her mess all day or does she want to have a nice fresh smelling bum bum with a nice soft fresh white diaper?"
The offer was, well, it was compelling, and while it all sounded good and well, and it was at that, Luna was not at all going for it. At this point in time, she stuck to her hooves in this department out of sheer spite, she'd been humiliated enough and she would rather sit in her wet, stinking sludgy wet shit all day long just to prove her point. Luna was very capable and willing to cut off her nose to spite her face. All those thoughts rolled through her head before she folded her hooves and pouted in the most adorable face, "Yes, yes I do."
But Luna was a baby. Celestia was the adult. And baby's always had to follow what the adult wanted. And so, regardless of what Luna wanted, Celestia approached her wittle itty bitty sister and plucked her out of the high chair with her magical abilities, levitating her up in the air.
Luna protested, but she couldn't really earn freedom, but it didn't stop her from attempting to squirm and wiggle and move wildly around, kicking and jerking. This only made that goo painted on her ass and crotch sink further in. The well-aerated portions of the contents sizzled into coldness, so as the content spread, Luna felt the mashing mushy temperature mixed slop expand new and untouched fur.
"Stop it! Stop!"
"Now, now, now. Don't you worry, big sister Celestia is going to make you all better?"
Luna found herself guided and levitated toward a changing station in the bathroom. Her body was gently placed down against the cool surface and the nimble precision of magical telekinetic touches glided against the diaper and undid it.
Of course, the filly had other ideas, and once liberated, she immediately tried to free herself from this humiliation. But not before straps roped around her arms and chest, tightly bundling her in and vicing her escape. It was tight, but not too tight.
This allowed Celestia the ability to truly concentrate on the task at hoof - which was to change that sordid filthy-filled diaper. It was strong and ever-present and no matter how odorous it was, it never disseminated nor lessened. It was a thick fog that overwhelmed the room entirely and without restraint.
"Thoust will pay for thee transgressions!!!" Luna howled, desperately struggling. It was useless and futile, yet she still tried. She was immobilized.
And so, the diaper was parted, the distinct sounds of Velcro pulled apart until the diaper unceremoniously popped open and exposed the filly filth. The smell was much more atrocious now that there was nothing truly containing it.
Luna twisted her face in disgust.
Celestia deviated her attention from the soft and maternal duties of cleaning a soiled little mare and pinching her own nostrils so that the scent couldn't crawl up her nose. Celestia even hummed to herself, casually doing this task as if it was just another little chore for her to do on her to-do list.
This infuriated Luna even more, her sister acting like this was just an everyday normal occurrence. This was vulgar and unprecedented and terrible and horrible. And here Celestia was... just... humming away. It really was like rubbing salt into the ego wound.
Luna felt her hooves lift as a baby wipe floated through the air, its cool clean surface started at the very back and gently wiped all the way in the front. While this happened, the dirty diaper slipped off and into a nice clean diaper pail, the lid shut immediately after, trapping that filth in there.
That sulfurous scent was still very outrageous and continued to sink into their fur, carrying the scent with them even without the scar-clad bum or the diaper.
"My, what a big stink and a big mess for such a little, little filly." Celestia teased, never-ending and enjoying the humiliation that she was exacting on her poor, poor little sister.
Luna just huffed in aggravation.
