Surveying the area in her Sheik disguise, Zelda observed the Fairy Fountain she was about to enter. Having hidden well for many years while she waited for the hero of time to return, she was starting to worry that Ganondorf was going to find her, having stepped up his attempts to locate her over the last few months. She had had many close calls recently, and they were only getting more frequent. While her disguise so far had served her well, it was starting to get a reputation as an enemy of Ganondorf which made her efforts to hide herself even harder. As a result, desperate times called for desperate measures. She couldn't allow herself to be caught, and thus she was going to seek help from one of the few truly safe refuges from Ganondorf's influence: the Great Fairies.

Having located none of Ganondorf's forces nearby, she crept from her hiding place and entered the fountain, feeling the barrier that kept evil away surround her, letting her breathe easily in the hidden passageway. She entered the glittering cave, slick stone tiles beneath her feet as moisture hung heavy in the air. There were thick yet gentle waterfalls tinted a soft pink surrounding the room that made it unclear if the walls beyond them were simply not illuminated, or if it stretched on for an unknown distance in total darkness. The lesser fairy fountains that she had sought refuge in before that served as a safe place for the small regular fairies lacked the grandeur and slightly surreal atmosphere of the fountain, having grand but normal walls and a simple pool of water rather than the decorated fountain of the Great Fairies. The exact level of power the Great Fairies had outside the fountains was unclear, but within their walls their power was absolute.

Zelda undid the disguise spell, breathing a sigh of comfort as her hair lengthened and hung freely, her tight and practical clothes replaced with the regal dress befitting a princess of Hyrule, golden earrings hanging from her long and pointy ears. She caught a brief reflection of her delicate face in the water, something she wasn't blessed with too often. The places she could undo her disguise were limited, as the magic she exuded in her natural form was easily detected by Ganondorf if not properly hidden. This fountain was one of the few places she could do this, and it was a good thing, as the request she was about to make was best made in her true form. She stepped up to the mark of the Triforce and began to gently sing the song of the Hyrule royal family, guaranteed to summon the Great Fairy immediately. No sooner had she finished than there was echoing laughter, the Great Fairy burst from the shallow fountain in a shower of flashy lights and sparkles, spinning as she continued laughing. She floated in mid-air and crossed her legs, assuming a reclined and comfortable position to address her.

Her body was naked other than her boots, her modesty covered by the trail of leaves running across her body and hair, the large trio of long pink ponytails that all the Great Fairies seemed to share floating lazily up and down behind her. The casual observer would have said that all of the Great Fairies looked the same, distinguishable only by hair colour, something that didn't help much in Hyrule where pink was the universal colour for Great Fairies, but Zelda had met all of the ones in the kingdom and noticed differences in the faces and bodies of each one. The Great Fairy had a carefree, almost ethereal smile as she waited for Zelda to speak. Zelda cleared her throat, and kept a tone of respect befitting of a being such as the one she was addressing.

"Great Fairy of magic, I come with a request that I hope you will grant."

"Well of course you do." The Great Fairy casually said in a pleasant tone. "The princess of Hyrule isn't one to come simply to say hello."

"I wish we were in a state where my visits could be simply for pleasure." Zelda admitted. The Great Fairies weren't much for formalities, and while she knew that they respected her position as princess, they would treat her much the same as any other being. Just being with them was relaxing, and she stiffened up again as she continued speaking.

"As you know, the forces of Ganondorf get stronger by the day, and the day of the hero's arrival is still far away. It is critical that I am able to assist the hero, but Ganondorf's forces are becoming harder and harder to evade."

"And so you come to me for help. No need to be so formal, dear, I'm quite aware of your struggles." The Great Fairy said. Zelda was determined to remain formal until she had finished speaking, though.

"I come to you to ask if I may remain in this fountain until the hero arrives." Zelda said, deciding to get directly to the point. "There's no safer place in all of Hyrule, if I'm to hide myself then I can go completely undetected here."

"A sensible idea." The Great Fairy said as she moved herself into a position of lying forward, still floating in front of Zelda. "One I'm sure you would only choose if you felt there was no other way to conceal yourself."

Zelda felt like she was being read like a book, and the unceasing smile of the Great Fairy didn't help. She grew hopeful. "So you'll help me?"

"Unfortunately, no non-magical being may stay for long in a Fairy Fountain. They may visit, but not stay. Not even you, princess." The Fairy said, Zelda's heart sinking as the pleasant tone didn't skip a beat. If anything, the smile widened as Zelda's expression fell. She spoke up once again after a few moments of silence.

"Now now, I didn't say that I wouldn't help you." 

"But you said..."

"Oh, my words are certainly the truth. But what if I said that there was a way to allow you to stay here for as long as you wish? Would you like that?" The Great Fairy said, her expression growing playful. Zelda's dropping hopes rose quickly, reflected in her voice.

"So it's possible?"

"Oh, of course. Do you promise now that you'll accept my gift to you?"

"Of course!" Zelda said without hesitation. The way the Great Fairy was speaking made her slightly uneasy, but they were benevolent beings. She wondered just how the Great Fairy planned to make this possible. Perhaps she'd grant her some sort of magical item, or make an exception with certain conditions? Either way, she couldn't afford not to accept.

"I do." Zelda firmly said.

"Then step into my fountain, my dear." The Fairy said, beckoning and floating away from Zelda. Zelda walked forward into the fountain, the cool water getting the hem of her dress wet as she approached the centre. Standing in the middle, she really realised how it wasn't much of a fountain at all. The deepest part barely made it halfway up her ankles.

"So, now what?" She asked as the Great Fairy's smile broadened. A pillar of light began to surround her, Zelda feeling extremely powerful magic around her, trying to figure out exactly what was about to happen. She realised that she was slowly being lifted off the ground, rising up to the now upright Great Fairy's height. Zelda took a deep breath and remained calm and waite to see what happened next. At least util suddenly her clothes disintegrated, and she squealed as she rushed to cover herself.

"W-w-what's going on? Why did you do that!?" Zelda squeaked out as she lost all composure, flushing bright red and flailing around as she tried to cover up her modest breasts with one arm. The Great Fairy simply laughed and circled Zelda, enjoying her girlish whimpered as she gently stroked her shoulder, apparently just to see how she reacted.

"There there, you said you would accept my gift, wouldn't you? Just relax and enjoy what comes next." She said, Zelda very much disagreeing with the idea of relaxing.

"And what exactly comes next?" Zelda demanded, getting no response as she corrected her position. She got no answer, and simply hung there for a minute. She kept readjusting her breast-covering arm, until she looked down and gave enough cry at the reason for why she was adjusting it. Her chest was inflating right before her eyes! Her breasts had been on the small end of a b-cup, but now they were blowing up steadily, her one arm unable to keep up with the flesh it was squeezing. She shifted one hand to try to cover each of the now c-cups separately, one hand going back and forth between her groin as she tried to decide on which one to cover, the Great Fairy simply enjoying the show. By the time she settled on giving up on covering herself they had reached d-cup, Zelda growing acutely aware of the Great Fairy's barely covered and quite well endowed figure, with curvy hips and a chest she now matched. However, her chest kept going, gaining an extra inch and a half before stopping, the Great Fairy giving an appreciative nod.

"What does this have to do with anything!?" Zelda shouted before feeling a creaking in her hips, realising that her hips were widening as well, growing wider than her shoulders as her ass plumped up, Zelda grabbing her new bubble butt with sheer embarrassment and confusion.

"Well, as I said, no non-magical being can live permanently inside a Fairy Fountain." The Great Fairy said breezily. "So..."

Zelda felt her hair brush the arch of her back, it previously reaching only a bit past her shoulders. She couldn't do much but watch it grow downwards in a luxurious golden wave, tickling her ass before going even further down to her knees. Once it stopped growing, Zelda, looking down at her reflection after trying to crane her head to see, watched it be swept up and divided into three areas, tying itself into an immediately distinctive and recognisible trio of ponytails; one on each side, and one in the middle, tied by nothing yet holding their form. Her blonde bangs hanging down in front of her ears were swept back as her hairstyle made her situation unquestionable.

"You're turning me into a Great Fairy? Can that happen?" Zelda asked, dumbfounded at the situation she suddenly found herself as she watched her fingernails grow longer, bright and matching the blonde tone of her hair as trails of leaves wrapped around her body and weaved through her hair.

"It's not very common, in fact, I would say you're lucky enough to be the first in centuries! Don't worry, we'll all give you a warm welcome into our family." The Great Fairy said, sounding very pleased at what she was doing. 

"But I can't be one! I have duties!" Zelda protested as the typical boots the Great Fairies wore materialised on her and her nipples and crotch were covered by leaves. She couldn't be a Great Fairy and a princess at the same time, let alone one actively fighting against Ganondorf! Could she?

"You said you weren't going anywhere until the hero arrives, didn't you?" The Great Fairy smugly said. Zelda felt that there was no point in saying that she didn't mean that she'd be here all of the time.

"But..." Zelda was cut off by the Great Fairy smiling and placing a finger on her lips, silencing her as they began to plump up, growing thick and soft like the Great Fairy's. Finally, thick yellow makeup, or at least what resembled it, appeared over her eyes, her eyelashes growing exaggeratedly long, thick, and dark, a beauty mark appearing above her puffy lips. Nearly naked and indistinguishable from the magical being in front of her besides her face, hair colour, and the fact that she was even more stacked, Zelda felt a vast amount of magical energy running through her, more than she knew what to do with. She realised that the pillar of light around her had vanished, and she was left floating freely, easily able to control herself. She was wide-eyed as she enjoyed the sensation of free flight before regaining her priorities and dropping to the floor, the Great Fairy giggling at Zelda's insistence on tying herself to her former status as a human. In a few weeks she'd never even touch the ground at all except on rare occasions.

Zelda tried to walk out of the fountain, but found herself stopped at the edge of the fountain. There was no magical barrier stopping her, but she simply couldn't move herself beyond the boundaries of the fountain. She couldn't even extend a hand out. She backed up and attempted to sprint out, but found herself sharply stopping herself at the edge. She lifted off the ground and flew at the edge, but made no more progress no matter what angle she took it from.

"I wouldn't spend too much time trying to leave the fountain, we Great Fairies reside in them for a reason. Even if you could figure out how to leave, you wouldn't be in a very good position. I would master my powers before trying that." The Great Fairy advised.

"I can't just sit in this tiny fountain!" Zelda wailed, all dignity lost at this point. "I'll go insane!"

"Oh, there's more to life as a Great Fairy than just this little room, I assure you. Well, I'll leave you to learn more about yourself naturally. Be sure to meet us all once you learn to use your power properly!"

The Great Fairy sunk into the fountain, Zelda diving towards her with a pleading look in her eyes.

"And be sure to treat the little ones kindly!" The Great Fairy called before vanishing entirely, leaving only a few fading sparkles in her wake. Zelda attempted to follow, but only succeeded in colliding with the tiles, luckily an act free of pain in her new body.

After a while of pleading to be changed back at the floor and some sulking, Zelda picked herself up out of the corner, unconsciously floating around rather than walking. Her disguise magic wasn't working, and neither was the rest of the magic she knew. It seemed this form ran on entirely different rules. She wondered if she could learn to apply her old lessons to the ones she would be learning soon. The Great Fairy seemed confident in her ability to figure it out for herself. Maybe she could conjure some more clothes. Or maybe not. Being so uncovered felt strangely relieving. Zelda tried to look on the bright side of her situation. Amazing powers, potential immortality, not that she desired that that much, the ability to grant the hero special powers... the ability to restore the damage done to her kingdom... a very unique position in the history books...

Zelda reclined back in her floating position and relaxed a bit as the pink-tinted waterfalls around her turned gold. Maybe she could make this work...
