“I’ve missed this,” said Twilight Sparkle as she raised a cup of steaming tea to her mouth.

“Missed what, Twilight?” asked Celestia, matching her host’s motion and raising her own cup of aromatic fragrance to her mouth.

“You and me, sitting like this,” Twilight replied, pausing to take a sip and frowning a hair as she noticed something off. Not unpleasant, it was just that something seemed to be missing from the moment. “Having tea like we always used to.”

“Not quite like always,” Celestia commented, a small knowing smile crossing her muzzle at Twilight’s look of surprise. “You might be the ruler of Equestria now, but I still know a few things.”

“I never could sneak anything past you,” Twilight chuckled, pausing to critically examine the tea. “I tried to recreate everything from our tea times together. I even made sure the window of this room was facing the same way so that the ambience was the same, but something’s missing. I know it.”

“You forgot the milk,” Celestia informed Twilight; her smile wide now below eyes sparkling with mischief.

“No, no,” Twilight countered, lifting a small silver milk pitcher. “I remembered the milk, and it’s in the tea too. Along with fire bee honey.”

“Oh, you definitely remembered milk, my former student,” Celestia responded, her horn aglow as she activated her magic and a small golden pitcher appeared. “But not my special milk that I always used for our times together.”

Eyes wide with realization, Princess Twilight set aside both their cups and drew a pair of fresh ones. Adding a measured dollop of honey to each, she held out both cups for a precise splash of milk from her mentor into both steaming receptacles. A pause, a sip, and a sigh of satisfaction.

“How did you know?” Twilight asked, relaxing into the moment. It was like old times. She was the faithful student again, sitting at the hooves of her beloved mentor as the ages old alicorn imparted yet another bit of wisdom.

“It is quite impossible for you to have access to this particular milk,” Celestia replied, sipping at her own fresh cup with obvious relish. “At least not without my knowing about it.”

“What do you mean?” queried Twilight, tilting her head as her insatiable curiosity was piqued.

“I mean that this particular milk is unique to our tea times together,” explained Celestia, her smile becoming a thing of satisfied pride, “and it has unique properties.”

“How do I get some?” Twilight half asked, half demanded. “I never realized how perfect it makes tea.”

“You can’t really, seeing as I’m the only source,” Celestia replied, denying Twilight. “Besides, it isn’t like you need it anymore.”

“Need it?” Twilight responded, her desire to know what was going on a flaring bonfire now. “What would I need it for, and why are you the only source? Surely somepony in Equestria has milk like this.”

“Well, you see, Twilight,” Celestia provided, setting down her tea. “It’s my milk, and by putting it into your tea on a regular basis, I was able to make sure you had what you needed to become an alicorn.”

“Wait? What?” sputtered Twilight. “What do you mean this is your milk? And what does it have to do with my becoming an alicorn?”

“Well, I couldn’t very well have you nursing off of me now, could I?” Celestia stated, utterly calm as Twilight’s eyes threatened to bulge out of her head.

“Your… your milk. From you. Not some cows you hired somewhere,” Twilight rambled. “Your milk, from your... “

“Teats. Yes, Twilight,” Celestia provided, still smiling lightly. “It’s not a bad word. And my teats are quite nice if I do say so myself. Nice and firm, packed full of what a pony needs to become an alicorn.”

“But what about all my trials and tests? What about the Elements of Harmony?” Twilight demanded, indignant. “What about Friendship?”

“Oh all of those things played their part,” Celestia confirmed, nodding her head. “But your absorbing some of my power into yourself through my milk, gave you that little extra push that was needed to make you into an alicorn.”

“So, would this work on anypony?” asked Twilight, overcoming her shock as her mind shifted into gear, possibilities, plans and lists coming to her. “You could make anypony into an alicorn, just by feeding them your… fluids?”

“Oh no,” replied Celestia, shaking her head. “Not just anypony. A pony would have to be blessed by Harmony, having done great things for Equestria. Otherwise it would just be milk.”

“So… “ Princess Twilight began, setting down her tea and making sure the two alicorns were alone. “Ponies like the Pillars, perhaps. Or like my friends, who are getting older every day?”

“Maybe,” Celestia replied, a frown crossing her features for the first time as she thought on what Twilight was saying. “But it would almost need me to be milked on a reg—”

Celestia never even felt the spell that struck her from behind and rendered her unconscious.

When the former ruler of Equestria regained consciousness, the first thing she noticed was the rattling sound of chains in her ears. The second thing she noticed was the rattle became louder as she began to move her legs, which was accompanied by an odd pressure on her fetlocks and a restriction of her motions.

“Mmrm,” was heard, as Celestia’s third discovery was the muzzle keeping her mouth closed in a soft yet unyielding grip.

That muzzle was just one part of a bridle that included blinders that kept her vision to either side blocked, and reins front and back which prevented the movement of her head in either direction. All Celestia could see in her limited line of sight was the tubular metal of a frame that bounded the small area that her restraints kept her in, as well as what appeared to be a treadmill below her hooves.

Experimentally, the alicorn took a step forward and was somewhat surprised to discover that, although her stride was definitely hobbled, she could walk forward and backwards on the treadmill with relative ease. Any attempt to move to one side or the other was prevented by chains that were attached to a body harness that had been strapped to Celestia, making its presence known via its pressure against her body.

Every bit of bondage fit the alicorn perfectly, as if it had been made specifically for her, by someone who had an exact knowledge Celestia’s sizes. So it was with more than a little trepidation that the captive pony drew power to herself in the form of magic to effect an escape. Celestia only pulled in the slightest bit of power, because whoever had bound her body so effectively was unlikely to have allowed the pony who controlled the sun unfettered access to her magic.

A minute later when Celestia returned to awareness it was with cramping nethers and an unspoken vow not to try to escape that way again. She had only drawn the merest fraction of power into herself when what felt like a thunderbolt had rammed its way into her most sacred place and exploded against her unprepared clit. The shockwave of agonizing ecstasy had ripped its way up through her core and utterly devastated her for what had felt like an eternity. Passing out had been a blessing.

“I’m sorry I had to let you do that, Princess,” said a voice from the surrounding darkness a moment later. Celestia’s head tried to jerk up with the shock of recognition, but was once again prevented by the martingale keeping her in place.

“MrrRdt?” asked the disbelieving princess, as to her shock her most faithful student, Twilight Sparkle stepped out of the shadows in the front of the treadmill and into view.

“Yes, it’s me,” confirmed the Princess of Friendship, making a notation on a clipboard she held. “Restraint testing, check. Discipline unit, check.”

“Mmrrrd!” demanded Celestia, chains rattling and straps creaking as she strained forward, demanding to be released.

“You can try all you want to get out of those, Princess Celestia, but all you’ll do is hurt yourself and accelerate the conditioning process,” Twilight responded, in a cool way that froze Celestia's body and soul. “Just remain calm and I’ll explain everything to you.”

“Frmmmmr,” was all Celestia managed to reply with, along with a cocked eyebrow that spoke encyclopedias worth of genteel reproof.

“I would do anything for my friends,” Twilight began, and Celestia felt a sinking feeling in her stomach as she realized where Twilight was headed with her explanation. “But my friends, good and wonderful as they are, aren’t immortal alicorns like me, who can look forward to at least a thousand years of life, if you and Luna are any sort of standard.”

“Mrrph Mmrd Brzz,” Celestia responded, trying to reason with her former student, trying to persuade her away from the pathway that the older alicorn now clearly saw that Twilight planned for both of them.

“I know, I know, and if there was any other way, I’d take it,” Twilight acknowledged, disappearing from Celestia’s restricted view and a second later the elder princess felt something new sliding up tight against her lower belly. “Your milk was the catalyst to making me into an alicorn, and what it did for me, it can do for my friends.”

“NNN!” Celestia tried to shout, as a rhythmic suction started up against her teats, pulling and sucking in an alternating pattern.

“I’ll do my best to take good care of you,” Twilight continued, coming back into view and tightening some of her captive’s restraints as she did so. “But the only way I’m going to have a hope of getting enough milk out of you to save my friends is to subject you to an intense regime of diet, exercise and alternative methods. In short, I need to treat you like a domesticated milk animal.”

“NNN! BRZZ!” came from Celestia’s muzzle, as she tried to writhe and buck herself free of the focused sensual assault, which had absolutely no effect other than to add to the tugging and pulling sensations on her nipples.

“It’s okay, I’m here,” Twilight soothed, stroking the side of Celestia’s face. “I promise to take good care of you as I help you adapt mentally and physically into your new role.”

“NNnNNn,” Celestia vocalized, trying to deny the situation she found herself in and making one last valiant attempt to break loose of her bonds.

“You didn’t try your magic,” Twilight observed, making another note on her clipboard. “I’d much rather condition you by rewarding good behaviour, but there’s definitely something to be said for the occasional touch of pain when training a new animal.”

Celestia moaned in combined pleasure and horror as she realized the depth of what her most faithful student had in store for her, and how she was already beginning to respond to it. All she could do was try to keep her mind and spirit intact until Twilight realized that her mentor wasn’t able to give milk any long—

“Oh look, there’s a drop already! I knew Zecora’s potion for new mothers along with some direct stimulation would get your lactation going,” cheered Twilight. ”I’m so proud of you ‘Tia. Good girl.”

Author's Note

Some of you are likely going, "But you were just getting to the GOOD part!" and that's a fair comment. The thing is I realized as I was writing that that I could go either dark or bright depending. So, as someone who stands between the candle and the star, I plan on doing both. One follow-on chapter will be a dark tale with a grim ending, while the other will be bright and cheery with a humorous conclusion.

This starting chapter is to give both of those endings a jump-off point to launch from. Hope to see you on the other side.
