This was an absolutely perfect short, thank you so much! <3

Twilight Sparkle paced back and forth before the great double doors to Princess Celestia’s bedchamber, trembling with anticipation. Having received a letter from her mentor early that morning, the little alicorn was awaiting a private meeting with the princess. As she had read it, phrases like personal matters and unique talents had caught her eye. Twilight, always eager, was counting the seconds until her meeting was due. It had to be soon. Any second now…
 
Almost as she thought this, the doors swung open before her, revealing the elegant form of Princess Celestia. The sun princess looked over her student with her usual calm smile and ushered her in. Twilight allowed her mentor to lead her over to a set of plush cushions and at the princess’s behest, seated herself on the smaller of the two. Celestia lagged behind to lock the doors, then proceeded to occupy the larger. Shifting a little in her seat, Celestia looked down at her student with a warm, wide smile and began. “Well, I see you made it.” she noted chirpily.
 
Twilight returned her mentor’s expression, but stayed quiet. “Now, I know my letter was a bit vague” she went on “but I’m sure you won’t mind a little surprise”. The younger alicorn, still silent, cocked her head to one side curiously. The princess watched her student with a slight sense of amusement and continued. “Now, hold still Twilight. I’ll explain everything in a moment.” she said reassuringly, igniting her magnificent horn. Twilight obeyed, trusting that her mentor knew what she was doing, and readied herself for the incoming spell.
 
A beam flew from the princess’s horn and made contact, bathing the little alicorn in a warm, golden light. Twilight felt weightless, almost intangible in her mentor’s magical grasp. The world was shifting before her eyes, her vision hazy and clouded. She could feel a soft sucking sensation within her very core, as if something inside her was being siphoned away. When the spell had finished it’s job, Twilight’s lucidity returned swiftly to her. Scanning the environment around her, the little mare gazed on as the various furnishings that she had seen on her way in now towered over her. Twilight deduced what had happened immediately; Celestia had shrunk her! The tiny alicorn had been rested safely on the cushion beneath her, which sank beneath her weight and was still warm from when she had sat on it.
 
The princess, looking down at her miniscule student, chuckled slightly and picked her up in a shimmering magical aura. Bringing the speck that was Twilight Sparkle before her face, Celestia began again. “I know this must seem confusing” she said with soothing air about her “but I hope you’ll allow me to explain”. Twilight, now held before her mentor, nodded meekly. The princess grinned and continued. “You see Twilight” she explained “long ago, before even the founding of Equestria, my sister and I developed a little tradition”. Twilight looked on curiously, wondering where this was going.
 
“We weren’t quite so powerful in those days” Celestia continued “so to increase and maintain our powerful magic, we needed to extract it from an outside source. That’s where you come in, Twilight”. The minute alicorn gazed up cautiously, beginning to deduce her mentor’s meaning. “You see, to maintain our power, we had to consume live ponies and absorb their magic. I confess, it was always an enjoyable experience.” the princess went on, somewhat losing herself now “They always tasted so good and made such satisfying wriggles. Ooh, it was so delightful! The weight, the texture, the fizzle of their magic!”.
 
Twilight observed this outburst with barely supressed trepidation and squirmed nervously. The princess, noticing the little mare’s discomfort, calmed herself and went back to her explanation. “Twilight, I’ve been watching you for a long time” she said “and as I’ve done so, I couldn’t help but notice your magic becoming ever more powerful with time. I must admit, you’ve always looked so delectable to me, Twilight. That’s why I called you here”. The princess brought her little student closer. Twilight could feel her mentor’s warm breath against her now. “I just wanted to thank you, Twilight” Celestia concluded softly “for everything”.
 
With that, the princess let her mouth hang open and gave Twilight a warm, wet, protracted lick. The feeling of her Celestia’s soft tongue and hot breath filled the minute mare with conflicted feelings. The sensation of the wet muscle against her hooves and underside, combined with the heat of her mentor’s mouth, was disarming, mind-numbing even. As the princess’s tongue coiled beneath her and the golden aura carried her inside the princess’s mouth, part of her mind, possibly the rational part, was screaming at her to move, to fight, to struggle. Anything! But the sensation of Celestia’s mouth was overwhelming. Being inside that warm, wet chamber filled Twilight with a strange sense of intimacy, the effect of which was paralysing.
 
The golden aura surrounding her faded, leaving her lying, immobile, upon Celestia’s tongue. Now unrestrained, she still did not struggle. The dull light around her faded as the princess closed her maw around the little mare. Twilight’s horn ignited, filling the mouth with a purplish glow. The larger alicorn gave a satisfied “mmmmmm”, causing the inside of her mouth to vibrate around her meal. Then, Celestia began to taste her student more thoroughly, tossing her from cheek to cheek within her maw.
 
Hot, heavy, slathered with saliva, Twilight made no attempt to resist. As she was pressed against the fleshy walls, the little mare knew she was beaten. At this point, she wasn’t even sure she wanted to escape. She belonged to Celestia now. The princess could do to her as she pleased. As her mentor, her devourer, grew tired of tasting her, she stared down the waiting gullet with a sense of resignation. With a gentle swallow, the princess sent her meal slithering down her throat, into the waiting sac below.
 
As the little bulge that was her ex-student disappeared down her oesophagus, Celestia grinned with satisfaction, a trail of spittle leaking from the corner of her mouth. Lapping up the salivate with her tongue, the princess gave a smile of contentment. Twilight Sparkle, her finest student, was now reduced to a little morsel in her gut. Feeling pressure building up inside her throat, she let out a triumphant belch. Twilight had submitted so easily, it was almost adorable. Now she just had to go through Celestia’s stomach. She wouldn’t last long in there. The princess would have her magic in no time.
 
Celestia rose from her cushion and went about her business. The sun princess had devoured more ponies than she could count, certainly more than she could remember the names of. Twilight was different though. Twilight was special to her. She had been a national hero, a faithful student and a good friend, not to mention a delicious meal, and Celestia would make sure, even if she was just magic and nutrients now, that she would never forget about Twilight Sparkle.
