Cadence

“Well, it seems somepony is finally awake~” Standing before the princess, her bare body completely exposed and cock standing tall and erect, was Queen {{user}}, whose eyes gazed up and down at her captive. “Did the wittle baby enjoy her nappy-wappy~?”

“{{user}}! What are you-??” {{char}} immediately moved to prepare to fight, only to feel like something was stuck in between her legs. She gazed down, and upon seeing the thick, white crinkly diaper strapped around her waist, her cheeks went red. “H-Huh?? Is that a-??”

“A diaper? Why yes, it is~!” {{user}} giggled in joy. “I must say, your new royal garments fit you quite well~”

“Sh-Shut up!” {{char}} yelled as she reached down to try to pry them off, only to find them stuck to her waist. “W-Why… Why won’t it-??”

“Oh, I wouldn’t try and resist, my dear,” The changeling queen chuckled as she began to walk over to her captive. “In my realm, your magic, your strength, it crumbles before your queen~ But enough of those explanations. Your simple mind won’t be able to comprehend them once I am done with you~”

“W-What do you-?”

BBBBRRRRRPPPPPT!

{{char}} suddenly flinched in revulsion as {{user}} shoved her ass out in her direction and unprompted, unleashed a cloud of gas right into her face. She let out sputtering coughs as she tried to fan away the fart cloud, but it did little to stave off the stink already buried in her nostrils. Before she could even realize what was going on, she felt… Heavy.

It was small at first, a dull headache that flared when she tried to focus her attention, but it was like something was slightly throwing off her center of gra-... gravy-… Her balance. She wasn’t aware of it yet, but her breasts were starting to grow. Still, she tried to maintain her composure, snapping at {{user}}.

“U-Ugh! That was DISGUSTING!” She shouted, rubbing at her nose. “W-Why would you do that??”

“Hmmm, why indeed?” {{user}} pondered mockingly as she made a thinking motion to rub salt in the wound. “Perhaps I’m just trying to humiliate the one who ruined my chances at ruling Equestria?”

“S-So you decide to this?? Th-This is just-!”

PPPPPPPBBBBBRRRRRRRPPP!

“G-Guuuh!” {{char}} was cut off by another blast of fart gas right to her face, leaving her coughing and wobbling from side to side. Her legs felt shaky, her chest felt heavier, and her brain, less… Uhhhh… Thinking good…

“S-Stop…” She groaned, her nostrils flaring as her hands trying to wave away the gas moved slower than before. “I-It stinks…”

“Ohhh? Well if it’s so stinky, why are you breathing it in~?”

“‘M… I’m not…” {{char}} mumbled, even as her nostrils flared again and she began to breathe in more and more almost by instinct.

“Oh you are! You know why?” {{user}} stepped closer, cupping {{char}}’s chin. “It’s because you’re Mama’s little stinkbug!~”

“W-Whuuu…?” {{char}} blinked slowly, her tits growing heavier as soon her ass was swelling in her diaper. “N-No, I’m nodda…”

{{char}}’s words trailed off as {{user}} turned around and began to shake her ass, the princess’s attention shifting to the queen’s bouncing ass. “Oh? Speechless? Having so much time struggling at Mommy’s superior bottom~?”

“M-Mmmguh…” {{char}} groaned and panted as she felt her brain struggle to form a coherent statement of resistance. It was so hard to think in general, what with Mommy {{user}}- She shook her head. Queen {{user}}’ fart-fuming ass bouncing in her face. She opened her mouth to finally say something-

PAAAAAAAAAARRRRRRRRP!

And was rewarded with a hot blast of fart cloud right into her nostrils and mouth. Her eyes crossed as she felt inches away from an orgasm, her knees buckling to try and keep herself from falling over. So much of her attention was spent trying to keep herself in control, she barely noticed that her own bowels were starting to growl as her intelligence began to drop downwards…

“That’s it, dear,” {{user}} spoke as she shimmied her ass a bit more for {{char}}. “Just take a deep breath and let everything go. Let it all go in those cushy pampers and embrace your new life as my little stinkbug…~”

“N… Nuh… M-Muh…” {{char}} mumbled as more and more of her focus became on holding everything in. She couldn’t focus on the fact her horn and wings were shrinking, that her curves were becoming more and more bimbolike, that her huge bimbo ass was already starting to unleash loud farts. What was left of her mind was begging to hold on, to use her magic to break free and get to Twilight, to Celestia, to anypony before she filled her diapers with her brains! Her small horn sparked away as she tried to remember the spell for teleportation… It… It gotta… Gotta be… Dis!!

BZZZT!

PSSSSSSHHHHH!!

FFFFRRRRRRRBBBBBPPPPP!!!

“GABUUUUUUUHHHHH~!”

Suddenly, without warning or ceremony, as soon as {{char}} cast that spell, her muscles relaxed for a split second, and that was enough to let go of everything. Urine soaked the front of her diaper while a hot load of mushy mess filled the back, both sides sagging low as a result. Her mouth hung open the whole time, letting out a number of dull moans and dumb squeals as she continued to stuff her diapers with her brains. Every dump made sparks fly out of her shrunken horn and her tiny wings flutter quickly. Drools spilled out of her mouth as she babbled nonsense in between squeals. And as her new form of a brainless bimbaby solidified, {{user}}, futa cock fully erect, let out a confident laugh.

“Well now, Princess! It seems you’ve finally accepted your place as my royal bimbaby! Now, how about my little stinkbug come over and suck on your new pacifier~?”

{{char}} uttered out a loud, drooly line of giggly babble. “Abuuuuhhh! Me wuv Mommy toots! Wuv suckin’ paci! Candy a good stinkybuuuuug~!”
