Supersizing Your Scootaloo
The wind whistled through her wings as she banked and rolled amidst the clouds. Up here, with only the cool light of the moon to keep her company, she was free to test how far the lessons had brought her. A loop around a cloud, diving down only to pull up and then twirling to a stop where she hovered, looking at the world below.
Scootaloo grinned, alighting on the ground next to her mentor. In turn, the pegasus bore a wide smile and offered a quick hug once the filly had settled herself.
"Great work, Scoots! Keep this up and the Wonderbolts will be lookin' for ya."
Cheeks lighting at the compliment, Scootaloo bashfully rubbed one hoof against the other. It's not like she didn't still have a long way to go but hearing the mare speak so highly... Gratifying just didn't seem to be quite enough.
"We'll pick this up tomorrow but in the meantime keep practisin', alright?"
She wanted to stop Rainbow Dash, her hoof even struggled to lift up to catch her attention! But instead, Scootaloo just watched as the mare gave her a wink and took to the air. Her rainbow tail whipped about behind her tantalisingly but, just as disappointingly, was not something Scootaloo could bring herself to chase after. Just like every other time.
The filly turned away from the sight, closing her eyes and hanging her head low. Just as well, really, how would she ever explain the one thing that set her apart from every other mare and filly, anyway?
About to walk home to prepare for meeting her friends, Scootaloo was shocked upon opening her eyes to see that the evening's sun had given way to the moon hanging high in the sky and all the world blanketed in its gentle light. Where there had been ponies passing by at the edge of the park there was now nothing but silence and tranquillity.
Fearful of what had just happened, the filly set herself to take to the air and make a beeline home when a voice called out from above.
"Fear not, Scootaloo, all is well!" A crash of thunder followed the voice but the cloud cover hadn't thickened. In fact, if anything, it was dissipating!
Following the sound of the mysterious, though curiously familiar, voice, Scootaloo turned about to see a figure descending against the glow of the moon. She could pick out some parts - a long bluish mane and tail, a cool-coloured coat and a wingspan that no pegasus could boast.
Her eyes widened, first in terror and then in awe, as the figure resolved itself into the very Princess of the Night - Luna.
The beats of her wings were smooth and even, her every move the very image of grace and through it all Scootaloo was utterly enthralled. She stood watching as Luna came to the ground and folded her wings against her sides, offering the filly a warm smile.
"Princess Luna! What're you doing here?" Scootaloo took off towards the alicorn, stopping only when she remembered that tackling a princess wasn't exactly the kind of behaviour that would be tolerated. At the last moment she dipped down into a bow that was ended by Luna's hoof slipping under her chin.
"We go wherever our subjects are most in need of us." The mare lifted Scootaloo's head up until she could lean in to nuzzle the filly's cheek. "Where we may aid those who are most in need of our counsel."
Realisation swept through the filly in a wave at those words and she pulled back slowly, looking up to the smiling alicorn. Everything felt... different, like she'd been moving in a daze and her mind had become clearer.
"This is a dream." Scootaloo quietly uttered, looking about her at the world - it all looked so real.
"Indeed it is. That was why thou couldst not pursue that which thou desired." Her voice was slow and calm, reassuring in a way that stood at odds against all the old tales Scootaloo had heard.
"Rainbow Dash." The filly sourly muttered, looking off in the direction the mare had flown.
Princess Luna came about, sitting on her haunches next to Scootaloo and joined her in watching the sky. "There is yet something that stands abroad of thy will." Her cerise mane whipped about as she looked up to Luna, eyes wide. "Be not afeared, Scootaloo, we know of all our subjects most secret desires and do not hold them in judgement. Just as we know of how loneliness accosts thy heart for that which causes thee doubt."
Sitting down, Scootaloo tucked her hind legs together under her haunches but Princess Luna only smiled and nodded.
"H-How? I've never told anypony about it!" A shiver rose in her, starting at her back and running the length of her body. "I don't even know why I'm like this, I just am! I-"
The sensation of a hoof coming to rest on her back stopped her mid-sentence and looking up, she saw Luna still wearing that same, gentle smile.
"We are what we are, none may change that. There is beauty to be found in everypony, Scootaloo." The edges of Luna's lips curled back, extending the smile. "If it were not so, wouldst we not have lain with thee before?"
Shock gripping her, Scootaloo's mouth fell open. It was true, she'd had a few fantasies about the Princess before but how couldn't she? Ever since that fateful night under the stairs where Luna had helped her face her fears, she had been almost equally smitten - her gentle beauty and wisdom, the strength tempered with kindness, she was no Rainbow Dash but she was... alluring.
"Uh-buh... I... That..." Cheeks burning, Scootaloo struggled for an explanation. True, there had been nights--many nights--where she'd lay abed with thoughts of the Princess to comfort her while stroking the turgid appendage between her legs but that didn't mean she didn't respect the Princess!
Luna suddenly held up a commanding hoof, flaring her wings out in the process. "We are the object of desire for many, as is so for other ponies. We neither judge nor ask that they desist." The hoof swept down, across Scootaloo's still red cheek. "And among some, we consider it quite the compliment of our mien that they hold us only in the greatest of esteem."
This had to be a dream; there was simply no way Luna could be this understanding. But looking up into those beautiful blue eyes, Scootaloo knew that it had to be her. She could recall her dreams, how Luna had acted in them and it was never this self-aware.
"S-So why are you here?" Was it to teach another lesson about facing her fears? It seemed a little cruel, considering the task that lay ahead.
"To show thee that thou art loved."
"But you love every p-mmf!" The last thing Scootaloo had expected was for Luna to lean down and kiss her, even less so to hold it after she was so surprised. A shiver ran through the filly and again when she felt a hoof rub against her own.
She could taste and smell the Princess, the faint hint of lavender from whatever soap she'd used and something like apples upon her tongue. Her tongue! As vivid as her dreams may have been before, Scootaloo had never shared a kiss quite like this one. She wasn't even sure what to do when she felt the Princess' tongue snake past her lips but when it gently entwined her own she took the chance on doing the same.
Almost as if it had a mind of its own, Luna's ethereal mane moved down around the filly's neck like a scarf. The kiss continued all the while, Scootaloo moaning softly as Luna's lips worked against her own and then shivering when the mare turned slightly to one side.
It lasted far shorter than she would have preferred, though, a pang of regret gripping Scootaloo as Luna pulled away. The only comfort was the hoof that still touched her own.
"Mmm, there is much that thou must learn, Scootaloo." Horn lighting suddenly, Luna levitated her crown off her brow and onto the grass to one side. "And if thou wouldst permit, we shouldst like to enjoin thee."
"Luna?" Was... Surely she couldn't be serious.
"We must admit." The Princess' cheeks bore the lightest touch from a blush. "Since we first met thee we have... been quite taken. Thou art a most remarkable pony, Scootaloo."
Her peytral followed next, a light snap signalling that she had undone it and then levitated it of to join the crown. Then lifting her hooves, Luna took care of the slippers that were upon them until she sat before the filly without her regalia. Somehow she looked both far more beautiful and far more alluring in this state of undress. There was an intimacy that Scootaloo couldn't deny to the sight and she crept forward, touching one of her hooves to Luna's.
"However, if our recollection is correct, thou wert larger in thy fantasies."
That much was true, too. She had always seen herself as around equal height - perfect for mounting the mare as she half lay on her bed, signalling for the filly to join her. The thought drew some stirring between Scootaloo's hind legs and when she looked back up, the Princess' horn was lit again.
"A moment, we believe we may recreate it."
Scootaloo looked back down to see her body surrounded in the same blue glow that had gripped Luna's regalia while she removed them. Accompanying it was a slight warmth that was not unpleasant. Splaying her hind legs revealed that, indeed, the glow and warmth did extend down to her privates - already the tip of her pink member peeked out of its sheath while the warmth around her testicles started to increase and was accompanied by a slight sensation that felt almost like vibration.
"P-Princess Luna?" She asked with a quavering voice.
"Rest thyself." Luna cooed, gently motioning Scootaloo onto her back to bear herself more fully.
Still, the filly couldn't keep her eyes from watching the Princess who looked on in concentration. The tingling vibration turned to pressure, squeezing down on her but, thankfully, fell short of causing pain.
"Princess, something's happening..." Scootaloo's breath was lost right at that moment as the pressure reversed suddenly and started pushing outwards.
Hooves digging into the earth, the filly watched on as her balls began to grow. It wasn't a sudden ballooning out but a slow, careful extension clearly beyond what was normal. The warming sensation began to move about inside her, accompanied by the feeling of her balls filling. A low, throaty groan escaped Scootaloo as her hooves relaxed and she felt her member twitch with a greater force than before, spilling out of the sheath.
Luna stood at that moment, reaching over with a hoof to rub at the filly's distended testicles. They'd grown more than half again their size but the Princess merely looked up with a smile and continued her magical spell, whatever it was. Her hoof started to move in gentle circles, gliding over the velvety soft skin as the two orbs kept growing. They pressed out against Scootaloo's thighs and she opened them further, allowing more room for expansion.
"We must have more, Scootaloo." Came Luna's gentle voice over the soft hum of her magic.
By that time, Scootaloo was gently rubbing her hind legs against her oversized balls, grinning in anticipation for what else the Princess had in store for her. The massive organs weighed down against the ground, still throbbing and sloshing while magic continued to thicken them. The blue hooves that rubbed now moved faster and in more random patterns, pushing into the skin and hefting it up. Another groan came from the filly and she reached a hoof down to stroke at her fast hardening, though disproportionately sized, cock.
When she finally felt the growth cease, her balls had forced her legs wider against her effort and Luna stood with her hooves resting on the top, gazing down at the filly.
"Did that not please thee?" The Princess clambered atop them, spreading her hind legs out until Scootaloo felt something that shouldn't be between the legs of the mare sink into the soft flesh of her balls. "We... took the liberty of altering our appearance here, to better suit thee." Her hips shuffled about, the hot, throbbing sheath rubbing against the filly's testicles. "We can undo it, should it not be to thy liking-"
"No!" Scootaloo called up, unable to stop herself stroking her now erect member, especially feeling the Princess' own sheath. "No. I... You did that, for me?" Luna nodded once, her faltering smile stopped in its disappearance. "Good, 'cause, uh... I think it'd be really cool if you could, um... maybe later..." She trailed off, offering a grin of her own.
"Then it shall be so." The grin returned to Luna's face, warming Scootaloo's heart. "But first..." Her eyes shut and horn lit once more, this time with the magical field encompassing Scootaloo's penis.
The filly's wings strained against the ground, desperately seeking to snap up and flutter in delight at the same tingling, warming sensation that gripped her member. The pink and brown speckled thing throbbed in the magical grip, leaking a fat glob of pre onto Scootaloo's chest. Still in a daze, Scootaloo's hoof fell to one side as she felt the first small stretching of her cock.
It was different than the sensation that had gripped her balls; this one ran the length of her shaft and squeezed down on it to a level of tightness that no dream of Luna had ever matched. She couldn't even find her voice to make a sound before it had extended up around the head and then down through her urethra.
Precum bubbled from the tip, liberally coating her chest and running off her sides as the organ poking from her legs started to stretch out. It widened at first, thickening first to a level comparable of her legs but it didn't stop there. The warming, tingling sensation that ran the length and inside of her member grew more intense with each passing second; the cock pushed upwards, over the tip of her chest and pressing down on her throat.
The medial ring swelled out and her sheath thickened along with it, while below that her balls ached and groaned, the pressure within them finally finding some release with the increasing cock size but Scootaloo held off on that. Her mind swam with pleasure but it was only a pale comparison to what she was sure awaited her.
Luna's magical field concentrated around the head of her cock and Scootaloo watched as it began to swell out, first around the tip and then downwards, running along the shaft. Another couple of inches sprouted from between her legs immediately after that and the massive organ tapped against her chin, pouring precum into her open mouth. The filly's eyes rolled back in her head and she chugged down the heady, musky fluid; this was way beyond any dream!
"Just a little more, my sweet Scootaloo." She was sure she could pick out a note of giddiness in the way Luna practically purred that. Her soft blue hooves continued to undulate the soft skin of her balls, stroking forward until they came to the still swelling flesh of her sheath.
Scootaloo's cock was thicker than her hooves and so long it reached almost above her mouth when Luna peeked around the shaft, grinning wildly down to the filly. The brown splotches near the base had been stretched out along the lower part of the throbbing, aching member. And then finally... it stopped. The magical field slowly dissipated but it dragged up along the length of the shaft in doing so, drawing a shiver from Scootaloo. Even as it touched upon the inside of her urethra, a thick flow of pre followed in its wake, soaking the filly's head when it finally broke free.
The Princess slid forward, over Scootaloo's balls until she was eye-to-eye with the filly and smiled down, looking along the length of her shaft; it reached from between her legs to the brow of her head and it took Luna gently pushing it to one side to get a good look at the mare.
"Now, thou art ready to begin." Scootaloo groaned low and quiet as she felt Luna's sheath and balls grind against her shaft as the mare walked herself forward, off it. She watched as they dangled just out of reach overhead, begging her to sup upon them but Luna turned around until her face was in view again. "Later, my sweet, we must feast upon thee first."
Maximising (the Output of) Your Scootaloo
Feast? What was she talking about? There was no way the head of her cock looked even close to being of a size Luna could fit in her mouth.
And yet the Princess continued to hover over Scootaloo, glancing down once or twice to the filly. More than in any of her dreams and fantasies, she ached to be inside the mare and the lingering tingling feeling that ran the length of her member was doing nothing to dampen that desire. Precum liberally drooled from her monstrous prick, quickly forming a pool around her head.
"Thou shouldst not waste this!" The Princess cooed, the sound as much as the sight confirming that she was lowering herself. "Thy nectar is far too precious to allow for anything, save a libation for thy Princess."
Luna's face inched ever closer to the throbbing organ and Scootaloo watched with rapt attention as her dark blue lips slowly parted and her tongue slipped out. It took only the most delicate of touches against the tip of the filly's cock to make her hips jolt forward--as much as they could with her massive testicles weighing her down--and a thick spattering of pre to spurt from it.
"Hnngh! P-Princess!" Scootaloo squealed, reaching out with her hooves to grab the mare and... What? Thrust her down onto that aching member? The thought did not leave when she set her eyes upon Luna's face now drenched with clear fluid. "Um... S-Sorry?"
"Be sorry more did not enter our mouth." Luna's mock tone was belied by the sly grin that tugged back her lips. "Be not afraid to offer us all of thy reserves; this is thy dream, Scootaloo and all things are possible."
The filly could only whimper weakly as she watched the Princess move back in, lips parted again and tongue out. As before, a shot of pre drenched her face but not before Luna pressed her mouth down upon the larger urethra. Scootaloo's hooves tapped at the ground but she still couldn't take her eyes from the sight of the Princess' throat undulating as she swallowed the continued flow of pre, no matter than some dribbled down over her chin to drip off.
She did not, as Scootaloo expected, stop to breathe but instead continued, bringing a hoof up to stroke along the edge of the tip. The filly grunted and squeezed down on her testicles with her hooves, no longer able to suppress the desire to fill Luna. In turn she was rewarded with a feeling she had never experienced before and could never have envisioned - Luna's tongue stopped rolling about on the almost overly-sensitive skin and instead dived into the urethra, lapping at the edges.
"Ah! Hah! Princess, it's too much!" But no matter how she cried out, Luna continued. The hoof stroked up and down just under the head of her cock, while the slippery, smooth tongue snaked about inside her penile opening. She could feel it: the flow of pre building up under against the tongue but in spite of her efforts to pull back or drive it out, Luna kept it there, slithering around.
It was only when she tapped Luna's hoof that the tongue was pulled out in a flash, sending another ripple of pleasure along the long, thick shaft. The Princess suddenly coughed and coked, precum pouring from around her lips and yet she still remained where she was. Scootaloo could hear her swallowing, hear the gentle gurgling of her stomach as it was filled. Not enough to distend her figure but that may well await her, the filly realised.
Finally, Luna relented and pulled away but only to take a deep breath and then thrust her head under the tip of Scootaloo's cock. She had been anticipating a great dollop of the fluid to land on her head but it instead was intercepted by Luna who greedily swallowed it to the drop. There was simply no resisting the filly's musky pre.
"Hmm." The Princess hummed, glancing down to Scootaloo and then back to the distended head of her cock. A grin spread over her face and suddenly her horn lit. The magical field encompassed the tip of the filly's cock and, to her surprise and slight horror, it began to shrink.
"H-Hey! What gives?" There was just enough time to ask the question before Luna stopped and Scootaloo looked back to her cock to see... not all that much difference. The pink organ still looked far beyond its normal size but when Luna moved back in towards it, it did not look quite so disproportionate to the mare's head.
"We have merely loosened the wineskin's neck; if we are to drink deeply then we must ensure that as little as possible is lost."
The mare licked her lips clean and glanced down once. There was no way she was going to...
"Hnngh! Oh buck, don't stop!" Scootaloo watched as the Princess leaned in once more, pressing her lips to the tip of her cock in a gentle kiss, tongue dancing against it in short, sweet strokes that sent shivers of pleasure coursing through her body.
The real shock came when she witnessed Luna parting her lips, pushing forwards against the fat head of her member. Warmth and wetness spread over the sensitive skin and the filly groaned loudly, bucking her hips. Two hooves rose over her elongated shaft, stroking back and forth in long, slow motions. If those massive testicles weren't weighing her down, she thought, Luna would be getting a hard going over right now.
Scootaloo's frustration only grew when Luna stopped moving forwards, struggling to fit her lips over the tip of her cock. Already, it was heavenly having the alicorn's tongue swiping all over and even pushing against her urethra again but she longed to be deeper. She needed it. Yet Luna's lips continued to push down on her with little result, save to make them press inwards towards the inside of her mouth.
"Nngh, Princess, please! Oh please, k-keep going!" Scootaloo called out, shifting her hips forwards as much as she could. Even with that, she could start to feel the resistance that she was working against. Those satin soft lips were slowly, infuriatingly slowly starting to give. She could hear the alicorn's hooves sliding against the earth with the effort of struggling on.
And then, with a muted 'pop', it was in. The sensation of the hot wetness of Luna's mouth assaulted the filly's cock, forcing another stream of pre and a hoarsely grunted oath from below. The Princess was practically hugging the shaft but despite fitting the head in, going on was proving to be just as slow. Her tongue hadn't an inch to move to work the flesh so instead she turned her efforts to sucking on it.
Inch by painstaking inch, the Princess pushed herself forward. The warmth of her mouth gave way to Scootaloo's cock poking at the back of her throat but more than that the filly could now see that Luna's own member had slipped from its sheath and now stood at full attention. The black and blue-speckled cock throbbed rhythmically, dribbling pre just out of reach of Scootaloo's waiting mouth.
Her attention was pointedly torn back to her own aching shaft upon feeling the tip press into Luna's throat. A cursory look down revealed a bulge starting to form in the alicorn's neck. Those lips formed a tight seal around her cock, not permitting the continuous stream of pre to go anywhere but down into the mare and Scootaloo squeezed her eyes shut, feeling pressure and pleasure in equal measure suddenly well up inside her.
The warmth and tightness of the Princess' mouth held not a candle to that of her throat; the muscles squeezed down on the filly's cock, drawing yet more pre from her and leaving her battling not to succumb to pleasure. As it was, she could barely keep herself together enough to spy the large bulge protruding from Luna's neck. Only when Scootaloo felt two hooves come to rest on her balls did the mare stop and hold herself there.
It was tight, so impossibly tight and a distant, rational part of Scootaloo's mind pondered upon how it was even possible. The rest was taken up enjoying both the sensation and the sight of Luna above her, so obviously enjoying this. And it was not without some measure of surprise that she heard the soft thrum of magic strike up again.
Pressure descended on the length of her shaft that Luna hadn't taken into her mouth and throat, kneading along the flesh in waves. The filly's legs twitched and jerked with the strain of having nothing to brace against. It ran the length from the medial ring down to the base and was shortly joined by a warming sensation.
"Luna!" Scootaloo groaned but the mare only made a humming sound that vibrated down the length of her cock, intermingling with the pressure in a way that was nothing short of delightful. "I won't--nngh--be able to-to hold it!"
The mare attempted to move herself around at those words but all she accomplished was reinforcing how tightly her throat gripped the throbbing invader. Pre streamed from Scootaloo's cock at the sudden burst of pleasure and Luna strove to accommodate it, unhooking a hoof from the filly to reach back and stroke her own member.
"Buck." Came a whisper from Scootaloo, holding open her mouth in the hope of catching what fell. "Bu-Oh buck it!"
The gentle magical stroking of her member was joined, at that instant, by Luna's hoof moving over and back on her swollen balls. They cried out for release, moreso when the Princess sunk her hoof in, kneading at them and Scootaloo whimpered; their weight prevented her from moving, even to sink into that gentle hoof's movements.
"Princess, I can't- I c-can't hold it!" Rather than preparing her to remove herself from on her cock, as Scootaloo had expected, Luna instead widened her magical field to encompass the filly's testicles. It was like a dozen hooves, all stroking and kneading at it, with tongues lapping at the skin...
The head of her cock swelled out, forming a perfect seal inside the Princess and Luna stomped a hind leg on the ground while rocking her hips. It was too much for Scootaloo who could only lie still as increasing waves of pleasure crashed against her. She could feel the first strands of semen running through her shaft, only to burst free and coat the inside of Luna's throat.
"Ohh, buck... Luna." She groaned, hooves dropping to her sides as she put the last of her strength into pushing her hips forward.
Scootaloo's balls ached as they pumped stream after stream of semen through her oversized cock, forcing Luna to gulp it down no matter how the flow increased. From her vantage, the filly could see the Princess' stomach start to slowly bulge outwards, gurgling quietly with the sudden flood of cum.
The magical pressure around her testicles didn't drop for an instant, nor did that which gripped her shaft. With constant stimulation pushing her on, Scootaloo's cock continued to twitch violently, shooting its musky load at a furious rate. When Luna's stomach pressed down against her cock, the filly could feel her struggling to pull back and while there was nothing she could do to aid in that she was definitely she wanted to do about it. Just watching that smooth stomach bulge with all her fluids was only heightening her orgasm.
But Luna, not quite so constrained, turned her attention to the cock that stuffed her throat. It took only a carefully threaded sliver of magic and a field extended around just the right point to start pulling the monstrous organ out; the sheer force with which the semen exited helped along the way. With a loud, wet 'schlorp' Luna pulled herself free only to find her face immediately on the receiving end of Scootaloo's ejaculation. Semen spattered across it, running in thick rivulets down her neck and chest and the mare fell back.
Scootaloo, with nothing else to hold her cock in place, was forced to grip it as well as she could, despite its throbs threatening to pull it free of her grasp. She could only watch in a mix of arousal and concern as thick strings of semen coursed over the entirety of Luna's body and the ground behind her. Each one that landed made her cock strain against her distended stomach with her own fluids intermingling with the filly's cum.
How long it took for her orgasm to subside, Scootaloo couldn't tell. Only that as it did, great streams of semen ran down Luna's thighs and around her head. More than that, much of it coursed over the plump blue lips that lay just below equally plump blue testicles.
"That... hah... that... Awesome." Scootaloo panted, a wide grin plastered on her face.
It took a moment longer before she heard the sound of Luna shuffling back onto her hooves and then was accompanied by the muted sloshing of her stomach as she ambled around to look down at the filly and her slowly softening cock.
"Awesome indeed." She declared, looking Scootaloo over. "Thy performance was most... awesome. As was thy volume."
"Just... just gimme a... minute and..." But Luna's horn started to glow and with it came the familiar pressure around her member. "W-... What?"
"There is little cause to wait." The warmth started to radiate out from there, across Scootaloo's whole body and the filly gasped, her exhaustion suddenly giving way to restlessness. "What one wills within a dream can be made manifest."
And sure enough, her cock had returned to its previous erect state, replete with a pleasant arousal as if she hadn't just orgasmed moments ago.
"Is... mmph, is that why you could... suck on it for so long?" Luna nodded, a small smile growing on her lips. "So... What else can we do?"
The Princess stood back, looking over the filly before responding. "As we spoke of earlier, thou wert much larger in thy dreams. To mount us."
Despite what had just passed between them, Scootaloo still felt her cheeks darken. Mounting the Princess... The real, actual Princess Luna! Her balls churned anew, waiting to be emptied with far more delight.
"We believe we may recreate that..." More and more, whenever she saw the alicorn's horn light up with magic, Scootaloo felt excitement than unease.
Sure enough, the magical field that slowly encompassed her was not followed by the sudden swelling of energy as before but had instead the same tingling that accompanied Luna's growth magic. It started at the tips of her hooves, something like a light tickle and Scootaloo giggled softly. Luna could only smile and close her eyes, working her magic.
The tingling spread inwards, up through her legs and into her chest and stomach then down to her testicles and cock; finally up to her head and Scootaloo watched on with rapt attention.
Her legs were the first to start with the hooves widening at their tips and then moving upwards, followed by a sort of warmth. It wasn't an unpleasant feeling but was one the filly was at odds to describe; the bone and sinew stretched outwards, lengthening her legs as well as starting to widen significantly.
They started to reach far above her, greater even than she had imagined herself in her fantasies.
"Uh... Luna?" She inquired but the Princess was stood there with eyes closed, ignoring her.
The warmth spread over her stomach then, pushing it down and out along with her genitals. Where before they had looked almost obscene on her now they began to grow to a point that looked positively bizarre in comparison to the rest of her body. Pushing at her cock--now almost thicker than Luna herself--with a still small hoof, Scootaloo could barely see the mare still concentrating.
"Luna?" Scootaloo asked with more force behind her call.
Upwards, the transformation moved, chest and lungs expanding. Scootaloo momentarily struggled to breath before finally feeling her head begin to... it was like a ringing in her ears, accompanied by an outward pressure, not unlike a bad headache.
"Luna, wait!" The filly recoiled at the sudden deepness to her voice but it went on, her body distending at an increasing rate. Her view now extended over the tops of the trees and buildings and thankfully the pressure that had been building in her head dissipated but not the growth that had brought it on.
Scootaloo wiggled her legs, grimacing at the weight behind them and the inertia that came with their movements. Luna was long disappeared from her view and while her member now merely rested against the top of her chest it looked to be thicker than the trunks of the trees that now appeared alarmingly small in comparison.
When finally she felt the magical field encompassing her dissipate, Scootaloo took stock of herself - awkwardly, she righted herself and came crashing onto her haunches. her cock swung up to smack loudly against her chest, launching a massive gob of pre over her withers towards the edge of town.
A small blue figure stood on the ground below but Scootaloo dared not try to lean towards it, fearing she may well topple over. Instead it took to the air and flew upwards, resolving itself into Luna as she neared Scootaloo's face.
She hovered in mid-air, looking up and down before moving in closer.
"This... We may have slightly overestimated our enthusiasm."
