After another long day at Canterlot High, Principal Celestia pushes her way into her office, closes the door, and collapses into her chair. At thirty-four (for the third year in a row), she is extremely tall for a woman, with most of the height situated in her legs. To her credit, she has maintained a trim and slim body, even in a profession marked by high stress and numerous opportunities to binge eat. There are some issues, of course; gravity has begun to take hold of her body, so what little pudge she has on her body is beginning to sag, and the crows feet around her eyes do little to make her more appealing. But both issues can be fixed with a little attentive care in front of the mirror every morning, and a tasteful sense of style.

She manages to hide her figure well, beneath a button down shirt and a well fitted business suit; snug at the shoulders and tapering inwards to hide the signs of aging around her middle and flaring out comfortably after reaching her waist. Beneath the clothing however, the Principal seems like a beanpole of a girl, still waiting for puberty to bless her with a woman’s curves even when set against her students. Especially a small but slowly growing number of them.

Pressing her index finger to her brow, she sighs and grumbles quietly to herself, “I’m getting too old for this.”

“Is everything all right, sister?” a clear voice rings out from the next room. Still feeling the stress of the day, Celestia rolls her head towards the sound and calls through the wall.

“Everything’s fine, Luna; just another girl coming to school dressed like…”

“A floozy?”

“Sure, let’s go with that,” the Principal sighs, rubbing her forehead again. “I just don’t know what’s going on with the recent upswing in clothing that’s rather racy-”

“And raunchy.”

“Right, that too. It’s just these girls keep coming into the school and they have no interest in being here aside from looking pretty and picking up boys. Or girls.” Hanging her head, Celestia groans. “How am I supposed to help these children if they don’t want help in the first place?”

“Truly a difficult position to be in, sister; but you must remember that we are a team and shall face this adversity together.”

“I suppose so. Thank you, Luna.”

There’s a long moment of silence, punctuated by the scratching of pen and paper on the other side of the wall. As the seconds tick by, the Principal manages to stuff her remaining frustration away and gathers her wits before moving to her computer. Even with the school day done, there is still work to complete. By the time Luna speaks, her sister is already settled back in business mode.

“In regards to the matter which we discussed earlier, I am still of the mind that we should isolate student Sparkle. She seems to be at the center of all of this.”

“While I understand your concern, we can’t go around accusing students of being responsible for something that is a natural part of growing up,” Celestia murmurs, tapping the end of a pen against her lip as she eyes her emails. “They’re testing boundaries, at home and at school. The best thing that we can do is be supportive and continue trying to push them towards a reasonable sense of dress and self-worth that isn’t tied exclusively to their physical appearance.”

“Even so, there is nothing wrong with setting an example for her ‘friends’.”

Celestia smile sand shakes her head at Luna’s grumbling. True, Twilight had always been a problem, but that was due in large part to the difficulties of being from another world. And besides, the girl had saved the school on two separate occasions, so she was allowed a little bit of leeway in the Principal’s book. Her sister didn’t see it that way.

Even though they were from the same family, the younger of the pair was slightly more self-conscious about her body, though she hardly needed to be. Having just celebrated her thirtieth birthday, Luna was still fresh faced and had a very even, naturally curving body. Where Celestia had gotten the nurturing, maternal instincts, her sister had received the figure. Still, the sometimes dour woman would complain endlessly about the low cut tops, high rising skirts, and overstuffed melons that seemed to be popping up throughout the school.

Luna’s heart was in the right place though and her concern with the well-being of students and staff could not be questioned. Celestia smiles as she spots the apple resting on the edge of her desk. As expected, her sister knew exactly what it was that she needed to get through this last little push of the day. Reaching out, the Principal snags the fruit. A slight surge of energy nearly causes her to drop the apple and gives her pause.

Static shock from a piece of fruit? That didn’t make any sense at all. She must have brushed against one of the pens out on the edge of her desk, and the resulting pink spark must have just been her imagination. Setting aside any concerns she might have, Celestia brings the apple to her lips and bites down without any hesitation.

The flesh is surprisingly tender, more so than she was expecting. The texture is less firm as a result, the meat of the apple falling apart inside of her mouth. While still delicious, the gritty sensation against her tongue causes the Principal to quickly set the fruit aside. She gives it a long look before shaking her head. Perhaps Luna made a mistake while shopping this week. But again, it was the thought that counted, and the gentle sugar rush was beginning to settle in.

With a renewed sense of purpose, Celestia sets to work, her fingers flying over the keyboard as she hammers out responses to emails from staff and parents. A Principal’s work is never done after all, only given temporary reprieve. Still, as the inbox slowly decreases in size, Celestia can’t help but smile.

Though she often kept a more upbeat demeanor when compared to her sister, the curving of her lips feels somewhat off this time though Celestia can’t place why. Parting her lips, she runs her tongue over them, feeling them for some sign of concern. In the end, she decides they seem al little swollen, though nothing that should warrant her attention. By the time she begins typing again, she’s already forgotten about it, unaware as the slender lips she was born with start to take on substance and weight.

Alongside the tick-tacking of her fingers, she hears a discussion in the room next door. Luna must have a student in there with her. Celestia closes her eyes for a moment and tries to ignore the voices, giving her sister and the student the privacy that they deserve. As Celestia shakes her head and resituates herself, she is woefully ignorant of the gradually growing pastel curtain of hair working its way down from her upper back.

With her attention refocused, the increasingly pretty Principal leans forward and squints at the monitor, re-reading an awkwardly phrased line in an e-mail. Even with her face softly scrunched, the creases of age begin to fall away, her the corners of her eyes filling in even as the orbs themselves begin to take on a bright and dynamic light that had been absent for years. In fact, her whole body seemed to be brimming with energy. Whatever was in that apple certainly gave her the kick in the pants she needed on a late afternoon, even in spite of the strange texture.

Finishing another response, Celestia grunts and stretches her arms over her head. In doing so, the oblivious Principal reveals that it wasn’t just her face and hair that had begun to change. Her shirt, once hanging somewhat loose and oversized on her slender frame, now starts showing signs of strain in the chest as her once suitably small breasts begin to swell. Likewise, as the sleeves roll down a few inches, they reveal a gradually firming pair of wrists and arms.

With a few moments to spare, the long-suffering Principal closes her eyes and tilts her head upwards, slouching deeper into her chair. The non-existent butt that had followed her from birth began to follow suit with the rest of her body, swelling in size and girth, circling around to increasingly broad, heavy hips that complimented her motherly nature. Not even her slender thighs were excused from the slow, steady march outward.

Interestingly however, the small points of concern around her middle had begun to disappear. Firming muscle and fading fat left Celestia with only a slight amount of womanly pudge across her belly, something one would expect on a woman of her age, even if she felt ten years younger. As she comes back form her break and begins to work again, Celestia the Principal again notices something that feels amiss.

Squirming in her seat, Celestia gives a frustrated grunt, noting that things didn’t seem to be fitting right, especially her pantsuit. What an unfortunate time for her period to begin early, she would have much preferred to be at home so she could slip into something more comfortable. Instead, she was locked away in her office and would have to suffer in silence until she finished.

“All the more reason to get done soon, girl.”

As she types out another email though, a thought crosses Celestia’s mind. Why did she have to suffer the uncomfortable tightness? She was, after all, the Principal of the school, with her own office, so what was stopping her from simply stripping down and working in her underwear? Fingers hover over the keyboard as Celestia considers her options, but finally she grins and pushes herself away from the desk.

The chair makes a violent rolling sound as it carries her to the blinds. With a flick of her wrist, they shut in an instant, causing the room to rely solely on the weak glow of the fixture overhead and the computer screen for light. Rolling back to the desk, Celestia glances over to the door. Any sort of reason suggested that she make sure that it was locked, but the idea that someone could walk in on her in such a precarious situation was utterly thrilling. Shifting her chair under the desk, she hides her lower body from view, bites the corner of her still plumping lip and begins to fiddle with her pants.

As the button comes loose, the Principal gives a satisfied sigh, already feeling the tension around her lower body begin to relax. Shimming from side to side, she forces the pants down past her thighs, stopping at around the knee. Her flesh-colored panties are still a little tight across her backside, but the excitement of doing something so unexpected helps to dampen the sensation somewhat. Confident in her ability to pull her clothing back into place and maintain her composure should anyone stumble inside, the energized Celestia sets back to work.

After another lengthy round of correspondence, Celestia takes another break. She notes that Luna’s office has fallen silent, and hopes that she was able to help the student with whatever problem they may have been having. Still unaware of her changes, the Principal taps her manicured fingernail against her cheek, the gentle natural color making her seem more in place as a student than an instructor. The soft, swollen state of her lips, while not excessive, is certainly attention grabbing, as is the sparkle in her eyes. Her hair, now thicker and more vibrant than before, stretches down past her lower back; though it does little to hide the state of her lower body.

What nature had once denied was now out in full force, the Principal’s curvy hips and thighs framing a plump posterior that would demand attention when she walked into a room. The boring underwear from before had changed into a snug, black lace affair, providing only minimal support but offset itself delightfully against her skin. Sometime during the latest round of emails she had kicked off her pants, which now lay in a crumpled heap beneath her desk for all the world to see. And, of course, there was her chest.

While not as sharply swollen as the rest of her body, the straining of her suit is still plain to see. Her button-down shirt has put up an incredible fight, shifting as the magic of the bimbo-apple ran its course, though it looks as if any more pressure will finally have it give up the ghost. Visible holes created by the Principal’s breasts showcase her sizeable breasts and a matching black lacy bra. Her suit has fared better, shifting and providing continual snug support throughout the process.

With its job completed, the magic gradually begins to seep out of Celestia, exiting through her feet and going into the ground. Of course, in so doing it manages to shift her sensible flats into a pair of ridiculous high heels. As the energy gradually leaves her body, the Principal feels a fog begin to lift in her head. Something, something was wrong.

She shakes her head and closes her eyes, trying to grasp what it is that was getting her so worked up. Pursing her lips, she takes a deep breath. Her suit and shirt creak in protest. And then, it hits her. Celestia’s eyes snap open and she scowls.

“Of course, it must be the apple.”

Reaching out, she grabs the fruit and glares at it. Even her serious expression seems cute now. After a moment, she turns the apple until she can no longer see the bite mark. Giving the flesh an experimental nudge with her thumb, she feels the firmness of the fruit and smiles.

And then she takes another bite.

Just as she thought, the flesh was less yielding on this side, far more like she was expecting the apple to be like in the first place. A bit of juice dribbles down from the corner of her mouth as she closes her eyes and savors the sweet sensation. As another surge of bimbo-magic enters her body, Celestia’s face and lips begin to tingle and the feeling quickly spreads across the rest of her body…




“So you see, Vice-Principal Luna,” Twilight smiles, sitting on the edge of the dark haired woman’s desk, “we should totally change the dress-code to be more accepting of certain girl’s changes in appearance and attitude. I mean, it’s only fair, and now you fully understand what it’s like to go through what they are, right?”

Luna gives the sultry student a lazy nod, her mind more focused on the touching and teasing her own fingers where doing beneath her panties. Gone is the pretty young woman, and in her place a bimbo-caricature rests; dangerous curves, melon-sized breasts, and a set of gorgeous nails that would put even Rarity to shame.

Inside, Luna was burning and the sooner this girl left, the sooner she could get back to more important things. Unless of course, Twilight wanted to help her. Before she can open her mouth, the visitor from another world glances over at the clock and smiles.

“Well, that should about do it for Principal Celestia,” she chirps, uncrossing her legs and bouncing to her feet. Luna stumbles to a standing position, the two finding their breasts comfortably squashed against one another in the small space between her desk and the wall. Twilight presses a finger to the Vice-Principal’s lips “What say we go have a look?” Again, Luna nods, her lips tingling in frustration as she resists the urge to suckle on the offered digit.

The duo quickly move into the hall and stand outside the door. After a moment, of preparing a victorious smile Twilight turns the knob and pushes her way inside. The grin quickly falters as she catches sight of the Principal. If Luna’s change had been a caricature, then Celestia’s could only be described as obscene.

Sitting in the middle of the room, Celestia gives Twilight a playful smirk. The act of conservatively crossing her legs may have hidden her snatch from view, but it only served to showcase the sheer vastness of her thighs. Pale, pink, and plump, they lead up to an equally boisterous bottom, sinking deep into the cushion of the chair. Her oversized hips show that even the magically changed panties couldn’t contain the sheer breadth of the Principal’s lower body. As Twilight’s eyes roll upwards still, the delicate, barely-there lady muscle of Celestia’s stomach is quickly eclipsed by her breasts. Literally.

With her middle cast into shadow by the enormous size of the Principal’s breasts, Twilight can only gawk open-mouthed at Celestia. At least twice the size of her head, Celestia’s chest is supported only by the single button that can be closed on her jacket, her bra long since discarded for being of inadequate size. As a result, her breasts are forced upward even more, giving her a gravity defying appearance to her otherwise exposed breasts.

The only small thing about her seems to be her puffy areola, and even that would be a stretch, as they successfully cap a decent portion of her massive mams. The pretty Principal smiles, finally drawing Twilight’s eyes to her face which, as with the rest of her, far exceeded Twilight’s original estimation.

“Twilight,” Celestia purrs, causing the girl’s cooter to clench in response, “so glad you could join me.”

Unable to find the words, the young girl glances about before her eyes settle on the apple. To her magic-trained eyes, it still glows with an electric pink light, save for the pair of large missing pieces. Gulping, she finally whispers, “You, had two?”

“I did, and I have to say that I’m not too pleased with how you’ve been acting lately,” the Principal smiles, leaning forward and forcing her breasts up and out of the improvised shelf, making them jiggle in a most wonderful way. Luna snaps out of her daze and hurries over to her sister. The two exchange a look, and then set their eyes on Twilight, sharing a knowing smile. Filled with uncertainty, the girl takes a step back.

“S-so what are you going to do to me?”

Celestia picks up the apple and gives it a long hard look. After a moment of consideration, she turns her attention to the girl.

“Well, to begin with you won’t be changing anyone else. You’re causing too much of a disruption by doing whatever you please.” Twilight’s face falls as she frowns, her eyes dropping to the ground. As much as she would like to say otherwise, the pony Princess feels somewhat… outbimboed by the Principal.

“All… all right. No more bimbos.”

“Now hold on, I didn’t say that.” Twilight lifts her head quickly. Celestia smiles and rocks the apple between her thumb and forefinger. “I just don’t want you to disrupt what should be a learning environment. So I’m taking over who gets changed from now on.”

After a moment of thought, Twilight nods and smiles. “So, I suppose you already have someone in mind?”

“I do, actually; tomorrow I want you to bring me another one of these apples. More potent if you can. And I want it delivered to Redheart.”

“The nurse?” Twilight asks, scrunching up her face. “But why?”

A slow smile spreads across Celestia’s face as she chuckles.

“Because I think it’s a waste to give her a room to work in if Redheart isn’t living up to her title and nursing sick students back to health. Do you catch my drift?”

Twilight bites down on the corner of her lip and nods. “I do, Principal…”
