you grin to yourself, hopping from hoof to hoof.

you're dressed in your finest tack; consisting of a well cleaned and polished bridal and reigns, your shimmering silver hair pulled up into a high pony tail. Your collar sitting comfortably around your neck, and a harness around your chest. Fingerless gloves that run up to just shy of your shoulders, and tight pouch boipanties, with garters attached to stockings.

You have your best horse shoes on and your hooves have been polished until they shine

Today, your mistress is getting home

You were often teased for having an elf as a mistress, since you yourself are a pony, that would make you taller than your elf mistress, right? Even at only five foot, most elf folk are not all that tall, but you'll show em and...oh there she is!

With raven black hair, pulled back into a long braid, and her face decorated with tribal tattoos. She stands at a skyscraping 9 feet tall, with biceps you could lose yourself in and abs you could grate cheese on.

Commander Elaine Winterbow, the half elf...half giant.

But even as your baby blues sparkle in delight at the sight of your mistress, you can't help but feel your eyes drop, roving over her large bouncing breasts, past the tunic hiding her hard, rippling abs and stopping at her muscular legs, almost like a horse herself!

or rather...the bulge bouncing between those thighs

you lick your lips

"Tenderhoof!" She calls and you trot over, your hooves clicking merrily as you leap into the air and are caught in the powerful arms of your beloved mistress, squeezed against her sweaty chest while the powerful knight-commander grins down at you

"I'm back my little one...and I brought you something!"

she shifts you so you're wresting against her hip like a a child would against her mother's

"yeah?" you gasp eagerly. It was customary for a knight to bring his or her squire back gifts from battles and adventures. It was a sign of not only how treasured the squire or squires were, but also the success of the knight in battle

It was true that squires cared for the every need and whim of their knight, however how a knight lavished their squires with gifts and the joy of said squire determined the knight's standing in social orders. A miserable, lonely or depressed squire meant that the knight was failing in their duties, and could even lead the knight to be stripped of rank

the stripe of a knight was determined not in how he or she treated their equals but rather how they treated their servants, their squires in particular

you bounce happily against your knight as she leads you through the winding path, to her manor.

"The servants should have delivered it while you were preparing..."

she places you down upstairs, in front of the doors leading to your room

"Go on little one, i have a few matters to attend to before we can begin"

with a wink she leaves, and your heart flutters...while your tail sways over your perky, proud buttocks. So eager to have that bulge...to care for it.

She's been away for six months, that's an intolerably long time for a knight to go without the tender care of a squire...and far too long for a squire to go without feeling the intimate dominance of their knight.

you curiously push open the door...and squeal

sitting on the bed, manacled and dressed only in a loin cloth is your noble twin brother

Twins you were: once stormrider and dawnstar. But you were taken by force by your mistress after battle and she changed your name to Tenderhoof...a name first filled with shame but one you now wear with pride and delight

Stormrider was bound by the will of his father's glory, seeking battle and greater riches to feed his father's legacy.

But Tenderhoof is free, unburdened by the demands of an old man. Free to be anything he wished...including a pretty, pampered mare to a large, dominating half elf.

When the realization of your newfound freedom struck,y you dove into the training with gusto, feeding off the shame and disgrace with a burning lust. Every bit of humiliation presented was consumed like a fine wine...savored, remembered and indulged. Now every scrap of the battle-weary and destiny-yoked Stormrider was gone

instead...replaced by Tenderhoof's soft, round and oh so eager ass that just begged for her mistress' thickness, soft full and kissable lips, large nipples for biting and nibbling, and a body built for sating the unslakeable lust of your dominant and sadistic mistress

All wrapped up in the tattoo of your mistress' coat of arms you wear on the small of your back

Now...Dawnstar. You know he looks upon you with envy and desire...yet it's hidden beneath walls of false macho pride, behind a false persona created by an overbearing and under emotional father's demands. A man who's greater years had long since passed him by, now trying desperately to expand his greatness at the cost of his son's happiness.

He did not care what their future was, only that his past was secured and remembered. You were not people...you were not his proud stallion sons, only extensions of his legacy, his personal dynasty. Wealth to be weighed and measured in a manner no different than the gold in his vaults and the bounties of his harvests

Arrogant asshole

But Dawnstar...

No, not Dawnstar

you run your fingers down your brother's filthy mane, dirtied and abused by battles and the unforgiving, thankless life of a soldier

but beneath the grime, the soot and filth you see the glimmer of your twin's silver mane

"...Starlight Racer" you redub him, though the newly dubbed Starlight looks at you with understandable confusion.

"your name," you explain, pulling your brother up and into the bathroom, where hot water and perfumed potions await

"But...But Storm-"

"no!" you scold pulling off his loin cloth, he looks embarrassed and squirms, his heavy equine member free

"no...I'm not Stormrider. Stormrider was angry, pitiful and miserable. I am Tenderhoof...and I am so very happy"

you push him into the water and a visible nova of dirty water spreads from his body

"oh boy...we have a lot of work to do"

you grin and kneel by the tub, and start to scrub with the potions...potions that will soften that coat, and hide his muscle, creating a layer of fat that will leave him looking softer.

"What happened to you?" your twin asked in anxious confusion

"Same that will happen to you. Happiness, freedom, joy...and a LOT of sex!"

He flushes brightly at your candid response

"Wh-what?"

"Lemme explain"

you start on his mane, to get back to that shining silver

"Mistress has a knack for picking out boys who have desperate longings, but are unwilling to admit it. Hidden behind walls and armor of emotion and self-serving lies, she strips those away...and leaves only the truth. But it's not easy...though it is kinda fun once you admit it is"

You wink at him and he...squeaks

"Your new diet will consist of potion-soaked foods, they will shift your weight around, leaving you with wide hips and a nice perky bubble butt that everyone will stare at" you lecture, the suds turning filthy from the dirt.

You rinse his hair

"Smooth thighs, willowy arms, you will look just like me. Which is sure to drive mistress wild!" You cackle mischievously, while he gulps, you drain the water to change it

"You will also have piercings. Your nipples to be precise: two bars pushed through made of enchanted healing metals. The spell will cause your body to repair the damage from the piercing, but the unfortunate side effect will make your areolas' swell up and grow large, and your nipples to lengthen somewhat" you pushed your own puffy chest forward for inspection

"Mistress calls 'em boi titties"

Your twin gapes, pretty lips parted and jaw trying to form words, futilely

"They're so sensitive...and soon you'll love it when she plays with 'em. She's also going to put a nice golden ring around your dick, behind your balls. This has a magic spell on it that will make you unable to cum until she lets you...AND it will make a fully operational copy come out of a second ring!"

Your twin brother looked shocked at that...and his face burned

"WH-WHAT FOR!?"

"Training" you cackle, and start to refill the tub

"That duplicate will become the single most important training tool in our arsenal! Believe me, i was super humiliated by it too, it was sooo shameful and sexy what she made me, and what you will have to do with it too!"

He looks afraid...and aroused, his cock twitching

"That copy will spend the next while in one of two places...up your ponyhole or in your mouth!"

He squeaks again, trying to vocalize a protest as he visualized getting fucked, daily, by his own dick!

"It will be part of your standard uniform! Always crammed up your ponyhole, grinding away inside of you as you walk, ensuring you are sporting a constant mare hardon for everyone to see, taunt, tease and play with."

You gather a second potion for another scrubbing of his hair and mane

"You will have to prove to everyone that you can deep throat it indefinitely, and swallow all the precum it spurts down into your belly, and of course you can play with it as much as you want. You're encouraged too!"

you realized later that this training was making you equate giving blowjobs and being stuffed with dick with blinding pleasure

as well as shame, disgrace, humiliation and being put on display for others to see

after all the training you went through, you feel positively over dressed now in your skimpy squire outfit

"At first you'll have to deep throat the dick-copy before each meal. The more you suck down, t he more food and drink you get. Then, you'll have to give it a proper blowjob, using your hands, mouth and tongue. The more satisfactory, the better your meals. Lastly...you'll have to blow mistress, in front of everyone!"

you sigh at the memory of the crippling humiliation and shame: having to swallow a belly full of semen before each meal often left you already full!

"And when it's not in your mouth, it's going to be pushed right up your ass!" you grin wickedly, and he whines, but his ponyhood is hard, a turgid pillar in the water

"And everyone will be allowed to play with it. In fact since you're new, mistress will probably reinforce your position of being at the bottom of even the other squires! You'd be forced to open your mouth for the other squires, like me! Sucking down our cum as our knights fuck us, or covering you with it. All the while you bounce on that thing...it feels so good and you'll become addicted to it, I promise!"

it's true

it's only a matter of time before new saddle squires are seen pumping, running or bouncing, trying to get the copy dick plugging their posterior to plunge deeper

"And you know what's super awesome?"

you start to scrub his coat, he looks afraid to ask, yet his eyes are a haze of lust

"Every week you're going to be boxed!"

"B-Boxed?" he stammers

"oh yes...Boxed. Boxing is when a metal clip is put into your nose, mimicking a nose ring. Then you're lead to a small glass box! Here, your ankles are pulled behind your head and tied in place, and your arms are tied to your legs: hands gripping and pulling apart your plump ass cheeks!"

your own marehood is hard as you remember the absolutely shameful ordeal that is boxing

"Then your own dick will be shoved down your throat, the real one not the copy! The copy is forced back into your butt, but this time it has a second gold ring on the back. A leather thong is looped around your nose ring and the plug ring and pulled tight, until both rings are touching and your balls are resting on your nose!"

he is breathing hard, eyes wide as he listens to you

"Then you're loaded into the box....and put on display for everyone to see, and use...

"u-use?"

he whimpers

"Oh yes" you all but purr, "I remember my first night. The other squires and their knights would come up...and open the top of the box, leaving my plugged marehole exposed to the sky. Then the squire would sometimes jerk off their knight, or bend over and get fucked by their knight. Either way the end result was the same...they'd cum on me. On my face, on my chest on my ass...all over me, before sealing the box up.

You are certain you see Starlight Racer's dick leaking into the water

you start scrubbing his coat with a pink potion, this will do wonders to keep his skin soft and supple

"By the time morning arrived, I was soaked in it. My skin was sticky, my body was rank with the smell of sex. It seemed like every knight and squire had cum all over me. I looked like a whore and I was so goddamn horny! And then Mistress pulled me out of the box and i...I had to thank her!" your face is burning with shame now, with lust and your own dick is definitely pooling a clear sticky substance on the ground

"it was degrading, it was humiliating! And then i had to blow her...right there in front of everyone, as if i hadn't had enough cock already! If she wasn't satisfied with my dick sucking...it meant next week I'd be spending another night in the box. I had six weeks of tasting my own dick and smelling my own balls before i was a pro and dick sucking, and you will be one too!"

he whines, openly whines like a frightened pony

"Oh stop worrying!" you scold, as your cloth moves over his chest and belly

"For a saddle squire, one of the most rewarding experiences is to be on your knees, your throat stuffed full and a massive pair of balls slapping against your chin. It's such a satisfying sensation" you sigh, lost in your own lustful thoughts

After a moment you realize your twin is staring at you, innocent eyes wide

"ah...ah yes. Once I had proven to her I could be a pro dick sucker,then I had to prove it to every other knight...I had to suck every knightly dick, one after another. my tummy was sloshing when I was done,a and I was delirious with need and lust. Sucking those dicks while they pumped my ass with the copy dick...i was going mad. I knew right then and there that I would do anything, anything at all, to cum...i needed it"

your twin is hanging off every word, every perverse syllable

"And so...I begged her. I begged my mistress to make me her mare, while my chest and face were on the ground, my big round ass up in the air and my cheeks spread."

you sigh in a manner normally reserved for brides remembering their wedding day

"And she did. She shoved the copy dick back in my mouth and claimed my marehole...she fucked my like a wild animal and when she came in me...when she filled up my slutpussy with her thick sloppy seed...I came. I came on the ground, and in my own mouth. "

your member is spasming and he looks ready to cum himself!

"it was the single most intense, powerful and crippling orgasm I had ever experienced. When I eventually came down from it...I realized i could never go back. I was now Tenderhoof...I was now my mistress humiliated, obedient, girly little dick dump. I craved her cock, i craved it being crammed in my hole. I wanted to wake up every morning with it shoved down my throat and go to sleep every night with it pushed up my hole. I would be as girly and feminine and slutty as needed. I would be a shameless whore if it meant she would fuck me...and let me cum."

your twin is entranced,terrified and terribly aroused

"And that is your fate. And her cock is HUGE! I mean i have to hold it in both hands when it's soft. You're going to feel full in a way you've never felt before...but only when you realize that you're ready to be her second mare."

the steady sound of footfalls filled the air

"...that's her coming now" you look into his terrified, excited eyes

"...don't worry. I'll be here every step of the way...and when you learn you love it, I'll make sure you NEVER forget it."

and the door opened.

You felt the copycock plugging your posterior spasm

Oh...yes...you could not wait.
