"Open wide sweetie here come the airplane!"
Rainbow Dash gurgled happily as the warm slop flowed down her throat. Mashed apple was her favorite flavor and Mommy knew it. The blue pegasus flaunted her arms in delight as Mommy prepared to send another spoonful of the delicious mush into her mouth.
Windy Whistles smiled lovingly at her daughter as she dipped her plastic spoon into the goopy slop of purple and pink baby food she'd been serving Rainbow Dash for the last few minutes. It had been several months since she'd taken her little bundle of joy to regression therapy.
The doctors had prescribed several medications, hypnotic tapes, and training videos. Dash had resisted at first but after a few weeks, Rainbow Dash had become the perfect baby eager for attention and mommy's love! It had been the best decision Windy could've made.
"Bwaaaahhh!~" Rainbow eagerly opened her mouth presenting her mouth to Windy. A mouth Windy was quick to fill as she sent the plastic spoon deep into the pegasus's mouth. Rainbow's tongue lept into action swirling around the spoon hungrily scarfing down the apple-flavored mush.
Her daughter had become so independent and outgoing since she'd moved to Ponyville all those years ago. she'd accomplished so much and come so far. Rainbow Dash had made friends, and some enemies, and lived a life all on her own. She'd even fallen into favor with the royal sisters!
Windy had been so proud of her little girl and all she had accomplished, however, she couldn't help but feel forgotten. She and her husband had been Rainbow's number-one fans for years; always cheering her on and supporting her in her time of need. But the support seemed to flow one way.
Rainbow Dash rarely visited them, let alone thanked them for all they had done for her. And while Windy was sure the rainbow-haired pegasus would get around to gratitude eventually, Windy Whistle often felt like Rainbow considered her a nuisance. The time Dashy had yelled at them in front of the Wonderbolts sprang immediately to mind.
"Ishhh sho tashty!" The Rainbow Dash babbled mid-swallow sending baby food and half-swallowed mush flying about the top of her high chair. It oozed from her mouth drooping onto the plastic table below and coated her onesie with sloppy stains.
"Oh my!" Windy giggled at the outburst as she watched Dashy squirm and giggle, oblivious to the mess she'd made. Her bib had been coated in drool and unswallowed milk for hours, and most of the food Windy had been trying to feed the little rascal had ended up on the table or around Rainbow's mouth.
"I'm duh besshh flyer!" Rainbow gurgled as her tongue flopped limply from her mouth allowing a continuous stream of drool to leak from her mouth.
Windy Whistles giggled as she set her spoon atop the highchair and reached for a stack of nearby napkins. "You silly girl!" WIndy cooed as she dabbled Rainbow's lips with the cloth. "Just look at the mess you've made! Naughty naughty!"
"Heh heh! Applsh tastiesh!" Dash giggled as she tried to pull away from the napkin eliciting a gentle crinkle from her diaper as it shifted and rustled between her legs.
"Ah ah ah!" Windy said with mock disappointment. "Don't get fussy with me young lady! Messy girls like you need to be kept clean and presentable!"
"B-buh... M-meshy?" Rainbow Dash repeated quizzically as something deep inside her woke up. Messy. She was a messy girl, and messy girls only had one function in life. Something she'd been trained to do whenever she heard the word, a duty she had to fulfill.
"M-meshhyy....." Rainbow Dash repeated once more as a dopey smile crawled across her face. "I-I'm a m-meshhyy gurll!~"
"Oop~" Windy covered her mouth in mock surprise as she realized what she'd just done.
Rainbow Dash felt a gentle warmth coat her body as her pelvis sank into the seat of her diaper and her bowels began to churn. The world around her began to fade and blur as her fingers tightened into a fist and her face contorted into a cute grimace.
A heavy mass began making its way through the pegasus's abdomen as her conscious mind slowed and trained suggestion took over. "M-messy gurl!" Rainbow grunted and puffed out her cheeks as she leaned forward in her high chair and pushed with all her might.
"Hnnnggggg!"
Windy Whistles watched her daughter with an approving smile as Dash helplessly tensed up and pushed her bowel muscles with all her might. This was what the regression therapy had been for, this was why she'd been so thorough with her daughter's training.
"That's it, sweetie, just push it allllll out~" Windy cooed encouragingly.
"Alllshhh outtsshhhh~" Rainbow Dash repeated as she felt her lower abdomen loosen and a warm log began to slide out of her backside. "Mnngggghhhhhh!~" Rainbow grunted as tingly pleasure shot up her spine causing her body to relax further as the log snaked around inside her crinkling diaper.
"Bwaaahhhh! Mommy!" The blue pegasus babbled as a feeling of relief surged through her body.
Rainbow's body went limp as her eyes rolled back in her head and the thick warm log of mushy mess settled in the back of her diaper. She moaned as all her remaining thoughts slipped into a fuzzy void never to be seen again. Drool flowed freely from her mouth coating her bib in blissful mindlessness.
Windy beamed with pride as she watched her daughter fall into the blissful void of fuzzy regression never to escape. Her daughter would never leave her again. Windy would handle her daughters' every need and desire; there would be no more worries or responsibility for Dash moving forward.
A gentle hissing echoed throughout the room as Rainbow Dash flooded the front of her diaper with urine. There would be no hiding how incontinent the little pegasus had become thanks to her therapy. Windy smiled as Rainbow's eyes drooped and she was pulled into the sweet embrace of sleep.
