Twilight turns Anon into a filly (TF, age regression)

>You received a mysterious invitation in the mail yesterday from none other than Twilight Sparkle.
>It instructed you to come down to the library for a talk about how you're adjusting to life in Equestria.
>So here you are, waiting patiently outside the library door in the early morning.
>You've already knocked once, but nobody has answered.
>You reach up and knock again, harder this time.
>You hear a set of hooves clop to the door.
>It swings open to reveal the purple mare, who smiles at you.
>"Sorry for making you wait. The princess and I were just talking about you."
>You look over to see the white mare depart from a table set up in the center of the room.
>"Indeed we were, thank you for having me Twilight."
>Twilight smiles and gives a little bow, before bidding her farewell.
>"Come in." She trots into the kitchen, reemerging with a tray of still steaming tea.
>You sit yourself down onto the princess' seat.
>Twilight levitates the tea onto the table handing you a cup.
>It's still hot, so you forgo drinking it for the moment.
>"So Anon, has everything been well so far?"
>You nod.
Just fine actually, some of the others are still a bit jumpy around me though.
>"They'll get used to you eventually, just give them some time."
>You can't help but notice a large book laying on the table next to you.
>You pull it over and read the cover.
>"A beginners guide to parenting?"

>Twilight blushes and looks away from your gaze.
Something you're not telling me?
>Her blush only worsens causing you to burst out into laughter.
>"Anon!" She whines.
I'm only joking around Twi.
>Still struggling to contain your mirth you take a sip of your tea.
>"I've been reading up on parenting techniques actually." She admits.
And?
>"I was curious about it, a topic I haven't broached before."
>Nothing new, even in the short time you've lived here and known Twilight she's read up on some awfully strange things.
>Thinking back to the other books you've found, you can't help but notice they're kind of connected.
>She started on transformation magic, something you weren't too surprised about given her position as a student.
>It slowly developed onto things that effect living creatures.
>One time you walked in on her turning a frog into a amphibious bat creature.
>She turned the poor thing back before it died, but even still it made her think twice about doing it again.
>Oddly enough she's recently turned her eye to parenting books.
>You don't get it, maybe Celestia made it assigned reading?
Why are you reading parenting books anyway?
>She hums and puts a hoof under her chin.
>"Celestia told me to after the bat incident, something about taking responsibility for living things."
Is that what you were both talking about?

>"Yep! The next step is to take some real responsibility. She says it'll make me a better pony with some real life experience."
So are you trying to get knocked up or something?
>She bites her lip.
>"Not exactly, I've come up with a much more efficient solution."
Why am I not surprised? Are you getting a baby pet or something?
>You take another gulp of your tea.
>Twilight flashes you a sly smile.
>"Hey Anon... want to be my foal?"
>Some of the tea goes down the wrong hole and you cough, causing it to dribble down your chin.
W-what? No!
>Her horn glows, freezing you in place, Twilight gives you a sheepish smile.
>"Well, too bad."
T-Twi what the FUCK
>A bright flash blinds you.
>Your body goes numb leaving you unable to move your arms or legs.
>A tingle of pain runs through the body and down your spine.
>You can't even muster the strength to protest.
>Twilight looks upon your paralyzed body apologetically.
>"I'm really sorry Anon! Celestia insisted that I do something to make you feel more at home."
>You gasp and your body begins to rapidly lose mass.
>Your clothing is pulled away as you shrink in your own skin.
>"So I thought, maybe I could solve two problems with one spell!"
>Your fingers and toes stiffen to the point where you can no longer move them.
>They slowly melt away into your new blocky limbs.
>"She loved my idea! Isn't that great?"
>You mumble helplessly as your tongue inflates in your mouth.
>A thin layer of white fur begins to creep across your body.

>"Oh, silly me! You can't talk obviously."
>She giggles to herself like a little sociopath as the glow intensifies.
>Your jawline moves outwards, leaving you with a horrible looking outcropped muzzle.
>Ribs crack and organs rearrange as your formerly wide chest is compressed down into the barrel of a small pony.
>It's only now you realize what she'd doing, she's turning you into a foal!
>Soon enough you can no longer see your own skin under a sea of white, fluffy fur.
>A purple bang falls down into your vision as your short cut hair lengthens and become silky.
>Twilight places you down onto the wooden floor as you writhe with newly regained feeling.
>Your male genitalia, a constant companion through the years, are sucked back into their cavity.
>In their place a small cave in, completed with a pair of delicate pink lips.
>Above them grow a pair of flat teats, complete with matching pink nipples.
>The world grows around you as your already reduced body is shrunk to the size of a newly born foal.
>Your eyes widen in their sockets, blue as a summer sky, tears already brewing.
>Twilight beams at her work, perfect!
>The dam bursts, and you wail like a child as you rock back and forth on the floor.
>Twilight looks panicked for a moment, quickly levitating the fucking book over to have a quick read.

>The pages fly by in a blur.
>"Aha!" she declares.
>Her magic grabs you again, flying you over and into her embrace.
>It's warm and mildly comforting despite the stressful circumstances.
>You feel lethargic and tired, no doubt a result of the spell.
>And not at all due to being wrapped in the warm arms of Twilight.
>Yeah that's it, you just need a small nap...

>Your eyes shoot open as you rocket up into a sitting position.
>Looking down to find your new, small, fluffy body is little comfort.
>Instead of fear, now you only feel anger.
>Large wooden bars block your way, she's put you into a crib.
>With a huff to blow your long mane out of the way you hit the with your new hard hooves.
>It creates quite the racket and catches the attention of the nearby Twilight Sparkle, who is in the process of reading some more.
>No remorse on her face as she picks you up from the crib and carries you back over to her reading space.
Twilight you fucking bitch!
>You yell in the cutesiest voice ever.
>Twilight looks down in shock.
What the fuck is fucking wrong with you! This is fucking insane! Turn me back right now you whore!
>And other such obscenities.
>This doesn't concern her as she plops you down onto the opposite seat.
>You cross your arms and pout like the foal you are, you aren't going to make this easy for her.
>She wants a lot of responsibility, she's getting it.
>She boops you on the nose with a hoof.
>"Bad filly! We do not use that kind of language in this house!"
>You look up at her, unimpressed.
>She winces and pulls the book back up, muttering to herself.
Hello? Purplesmart?
>she ignores you and looks out through the window.
>"Maybe..."

>She slams the book back down onto the table.
>Your little heart skips a beat as she gets up into your face.
>"Now listen here little Missy, you're not going to use that language in this house again or there will be trouble."
>Unlike earlier her scare tactics aren't going to work.
I'm not a foal you crazy bitch, turn me back.
>She sighs and leans back into her chair.
>"I warned you."
What are you going to do, wash my mouth out with soap?
>Her horn glows again, and fear blossoms in you again.
>What is she going to do now?
>The glow surrounds you again, but nothing happens.
>You open your mouth to gloat, before coming to a horrible realization.
>All it once you notice what Twilight has done.
>You barbed insult comes out as nothing more than childish babble.
>Your memory is wiped clean of any swear or curse.
>And you find is exceedingly difficult to form an effective, coherent thought.
>In fact, she well enough wipes away your entire memory.
>Your life as a human.
>Gone.
>Your time in Equestria.
>Gone.
>Yet you retain the knowledge that you knew these things before.
>She's taunting you, leaving a small inkling of what was once there to mess with you.
>But you can't muster the anger to care.
>For the first time, you really feel like a helpless child.
>When you look upon Twilight you don't see her as the cow who stole your junk.
>Instead you see a mother.

>You shake your head, no!
>You aren't that far gone yet.
>You can still remember what she did to you.
>Scowling at her, you look away.
>Twilight actually looks a little irritated about that.
>Your little tummy rumbles, catching her attention.
>"Is my little girl hungry?" She asks in a moronic baby-talk voice.
>Just ignore her An- What was your name again?
>Twilight doesn't notice your internal distress and picks you up before moving onto the bed.
>"I've prepared for this part! A young filly like you can't eat solid food, so I've casted a lactation spell on myself. It'll be like I'm really your mother!"
>She lies down on her side, giving you a clear view of her modest teats topped with dark purple nipples.
>A small dribble of white milk leaks from the fleshy mass, and you can't help but lick your little lips.
>"C'mon, drink up." she titters.
>You gravitate towards them against your will.
>And before you know it you've wrapped your mouth around the rubbery nipple and have began sucking eagerly.
>"Oooh! That feels weird."
>Warm milk floods your mouth and pours down into your stomach.
>You didn't realize how hungry you were until now.
>All your worries seem to melt away as you focus on suckling your mothers teat.
>"Thats a good girl." Twilight coos, rubbing your head in encouragement.
>Soon enough you've had your fill and pop off.
>Twilight sighs and pulls you onto her much bigger chest.
>You muzzle into the soft fur, enjoying her warmth.

>You can't seem to remember what the fuss was about earlier.
>Something about mommy annoying you?
>That doesn't seem so important anymore.
>You can't stay mad at mommy.
>You let out a little belch, Twilight sits up and wraps her hooves around your petite body.
>"Somepony needs burping." She whispers.
>She pats your back, causing you to burp several more times.
>It's oddly relaxing and soon pulls you back into lethargy.
>Lethargy, that's a big word.
>You let out a tired giggle.
>"What's my little girl laughing at?" Twilight asks.
>You smile and boop her nose before returning to the crook of her shoulder.
Love you mommy.
>You murmur before drifting back off into sleep.
>"Love you too... Anne."
>She kisses your head, she could get used to this kind of responsibility.
