Twilight's New Life

"Twilight Sparkle! I, Trixie the Great and Powerful, have come for you! Today we duel!" Trixie yells outside of the castle library, waiting for Twilight to come down.

Twilight rolls her eyes and walks down the stairs, stopping at the doorway. "What do you want now, Tri-" Twilight lets out a cry of shock as she's lifted in the air, Trixie's horn glowing a bright blue.

"Silence, Twilight Sparkle. I am in charge now. Move aside." Trixie moves Twilight aside with her magic and walks into the library, Twilight still held in a blue bubble.

"What are you going to do, Trixie? Princess Celestia won't let you get away with this, whatever it is!"

Trixie chuckles, settling herself down on the library's floor, her back legs spread wide. "Silly little Twilight, Princess Celestia has no power over me. Or what I'm about to do to you." With that said, she concentrates hard, moving Twilight effortlessly towards her, the alicorn struggling fruitlessly.

"Trixie, put me down! This is a very stupid idea whatever it is you're planning!"

"Oh no, my darling Twilight Sparkle, it is a very good idea. Now close your mouth."

Twilight's eyes widen as she's pulled towards Trixie's wide open vagina, still trying to get out of the glowing ball of magic she's trapped in. No, no, no, no.

"Don't worry your little head, Twilight. You'll be just fine after a little rearranging." Trixie grits her teeth as she uses her magic to slowly ease Twilight's still struggling body inside her. "First the back hooves and your cute little tail then your Cutie Mark - hope you enjoyed the last look of it - then your wings - oh Mama's gonna love getting those - and finally the rest of you. Get cozy, my soon-to-be-little filly."

Twilight lets out a muffled cry as she watches her body slide inside Trixie's gaping vagina until all she can see is the slick pink flesh and then nothing but blackness. Twilight squirms in displeasure as she feels her body shrinking and the baby fat bubbling up on her limbs. She sobs quietly as her Cutie Mark fades away, leaving nothing but a blank flank. She squeezes her eyes shut as ripples begin to rock her fleshy prison and she feel the muscles pushing her outwards over and over.

Trixie groans and pushes until a sopping wet infant-sized Twilight slips outside. Trixie smiles over the newborn foal, admiring her tiny hooves and miniature wings and itty-bitty horn.

"There we go. Mama Trixie's all ready to take care of her new baby Twilight. And you look so cute with your little wings," Trixie murmurs, beaming and nuzzling at the new foal.

Twilight glares at the unicorn and Trixie just chuckles, nudging her towards Trixie's dripping teats.

"That glare doesn't affect me, little one. Now then, it's time for someone to eat their first meal so they can grow great and powerful like their Mama."

Twilight finds she doesn't have much choice in going places as Trixie's quite able to overpower the little filly. She reluctantly opens her mouth and some of the sweet creamy liquid falls inside.

Trixie smiles down as the hungry foal latches onto a nipple and greedily begins nursing.

"Mmm, there's Mama's good baby girl."

Eventually the warm milk, combined with the stress of the day, sends Twilight nestling against Trixie's chest and falling asleep. Trixie hums and rubs the little filly's back, smiling down at her.

"Yes, you'll be Mama Trixie's sweet little foal, doomed to spend the rest of your days in diapers." She leans down and nuzzles Twilight's muzzle gently, pressing a soft lick to her nose. "Nothing but warm Mama's milk in your tummy. And you'll love every minute of it," Trixie finishes, placing the deeply asleep Twilight in her crib.

Twilight stirs and rubs her eyes with her hooves, sitting up on a plush surface. Bars? Where am I? She glances around her, taking in the soft pastel colors and light-colored wood furniture. This looks like a nursery? Twilight hums and attempts to stand on her legs but she falls over almost immediately, landing with a soft thump on a very padded surface. She sniffles, tears already welling up in her eyes at the shock. She presses a hoof to her backside, recoiling in shock at the smooth padded surface. Is this a diaper? What's going on? She starts to cry, big tears dripping down her face as her crying rises in pitch until it just sounds like the tortured wail of an infant.

Hoofbeats sound as the door opens and Trixie rushes in, heading to the crib and lowering the bar via magic. Trixie coos and dips her head down to kiss the newborn's forehead. "Shh, Twilight, don't fuss. Mama's here, Mama's here now." Trixie barely has to concentrate before her horn's glowing and Twilight finds herself floating in the air and then carefully balanced between Trixie's enormous blue wings.

Twilight gapes at the sight, her former rival's wings seem to go on forever and she reaches out a hoof to gently stroke the feathers. The little alicorn shifts around, feeling Trixie walk over to the changing table and levitate Twilight onto the lightly padded surface.

"Mm, there we go, little one. Let's get you out of that old diaper, huh?" Trixie hums and pulls back the wet diaper, cooing as Twilight squirms on the table. "Aww, my little Twily. You'll be fine." She swiftly pulls out the soiled diaper and tosses it in the trash, wiping Twilight and then sliding a fresh thick diaper underneath the foal. Trixie leans over and blows onto Twilight's belly, smiling as the infant filly lets out a babyish laugh. "There we go. A nice clean diaper for Mama Trixie's baby."

Twilight opens her mouth and starts. "Trixie, this is very unbecoming. I am a Princess and how dare you treat me like this. Turn me back to normal immediately."

Trixie laughs. "And a 'mababa' to you too, sweetie."

Twilight's mouth drops open in shock and she starts to sob.

Trixie coos softly and carries the newborn over to a cozy corner loaded with pillows and a nice plush rug. She lays down on it, gently placing Twilight between her legs and guiding the shellshocked foal towards her engorged teats. "Mmm, Mama knows the best way to cheer up little foals is to give them a nice full tummy of milk. Go on, Twilight, drink up."

Twilight fusses and squirms, trying in vain to avoid Trixie's hoof. She shakes her head, glaring at the bigger alicorn.

Trixie sighs and levitates Twilight against her, humming softly as she maneuvers the infant to press right against a swollen teat. "Looks like Mama's going to have to do this the hard way, huh, sweetie-pie?" She eases Twilight's mouth over a nipple and squeezes the flesh with a hoof, smirking as Twilight's eyes widen when a rush of milk floods into her mouth. "There we go, baby. Mama knew that'd make you feel better. C'mon then, keep drinking. A full tummy and a nice nap with Mama'll make her cranky little Twily feel much better."

Twilight reluctantly swallows the milk, struggling in vain to stop drinking but her infantile instincts overcome her and she begins nursing steadily.

Trixie sighs happily as a large wing wraps around Twilight, keeping the foal contained and cozy. "Do you know the best part about all of this, my darling little Twily?"

Twilight looks up at her around a nipple, still nursing solidly, and shakes her head.

Trixie cradles Twilight with a wing and gently strokes her mane with a hoof.

"The best part, little one, is that, thanks to my new magic and that yummy milk you're drinking, you'll be my sweet darling foal. Forever."

Twilight squirms and struggles, milk dripping out of her mouth, trying to escape but Trixie's hoof holds fast.

"Oh, I know, darling, I know but don't you worry. Mama Trixie's gonna take such good care of you that you won't even miss your old life as a Princess."

With her other hoof, Trixie presses down on the teat Twilight's currently attached to, releasing even more milk into her mouth.

"Drink it all up, baby."

Twilight silently sobs, tears rolling down her cheeks, even as she's forced to continue swallowing the milk. She continues to sob as Trixie coos softly at her, the blue adult alicorn's horn glowing softly. Twilight finally manages to tear her mouth away from the nipple and tries to speak, slowly saying despite sniffling every so often. "Trixie, I want you to turn me back. Equestria can't- I need to be out there and Celestia-"

Trixie laughs out loud, wiping away Twilight's tears with a gentle hoof. "My sweet little Twilight Sparkle. Celestia has no need of your services; you're just a newborn foal. Whatever could you do to help?"

"I I'm the Element of Magic! The Princess of Friendship! I'm not your little foal!"

Trixie smiles down at Twilight, still chuckling. "Oh, my dear little one. Celestia and Luna love their new niece very much but they both know who the actual Princess of Friendship is and it's not Mama Trixie's darling itty-bitty Twily. Let me show you who is." Trixie raises her head and levitates over an achingly familiar crown and places it on her own head.

Twilight gapes at Trixie, shaking her head fiercely. "No, no, no, no, no," she babbles. "This is a nightmare and I'm gonna wake up soon and everything'll be back to normal."

Trixie sighs, placing the crown back with a quick swish of her horn, and pulls Twilight against a teat, tickling the infant's mouth with a nipple. "There, there, little one. Just nurse and everything'll be all right."

Twilight lets out a muffled whine as milk gushes into her mouth and she swallows it down, still trying to talk even with a torrent of milk. Eventually she gives up and succumbs, steadily suckling Trixie's teats, little hooves squeezing the soft flesh. Her eyes close as the warm milk and the shock of the day eventually lull the little filly to sleep.

Trixie smiles down at her and lets out a yawn herself, using her magic to gently rearrange Twilight into a more comfortable position as Trixie wraps a wing around her napping newborn and settles down for a nap herself.
