Sol had been having a perfectly normal, boring, day. College had ended for the quarter, so he was stuck at home with nothing to do on his day off. His brother, Apollo, was in his room playing his games while Sol sat about watching some television. That was about when he heard the faint sound of cursing from his brother's room and, chuckling to himself, decided to go see what was wrong.

Sol paused the movie, and headed off to see his brother, pausing to see how he looked in the mirror on his door. Tall, fair-skinned, and wearing jeans and a white shirt with a sun-mark on it. His eyes were an odd, but beautiful violet. Sol noticed that his hair was starting to get a bit long, even interfering with his eyes a bit. Grumbling slightly as he brushed his red hair out of his face, he continued on to where Apollo was playing some computer games.

Apollo had his face down on his desk, whimpering slightly, his short, dark blue hair cascading around his face. Apollo was slightly shorter than Sol, and was noticeably darker-colored. Sol only had to glance at the screen to know the problem, and chuckled.

“Shut up." Apollo grunted. He didn't have to look up to know why his brother was laughing.

“Aww, but Apollo," Sol grinned.

Apollo's head lifted just enough to glare at Sol with dark-blue eyes. “No. No laughing."

Apollo was dressed similarly to Sol was, just with a moon on his shirt rather than a sun. He also preferred slacks to jeans.

Sol's grin grew wider. “Even if you lost zero to --"

Apollo decided to interrupt Sol's taunt with a perfectly thrown pillow. Sol laughed a bit more, but was interrupted by Apollo's cell phone going off. The call was answered promptly.

“Hey, Matt, what's -- oh come on!" Apollo cried, throwing his arms up. “I didn't get my -- no you did not kick my ass! Shut up!"

Sol had to cover his mouth to keep from bursting out laughing. He could hear Matt's laughter, even at this distance. Apollo glared at him out of the corner of his eye, then turned back to the conversation.

“You've got my bro laughing too, what do you want?" Apollo's expression changed from sour to surprised. “You want to meet somewhere?" He glanced at Sol.

Sol shrugged. “I'm up for it. We're not really doing anything."

“Alright, we're up for it, Matt. Where to?" Apollo's expression changed to confusion. “Where? A... costume store? Uh... okay. See you there soon." The call ended and Apollo stared at his phone. “That was... weird."

Sol looked just as confused. “A costume store, you said?"

“Yeah. He said something about the owner wanting to meet us for some reason."

Sol shrugged and headed down the hall towards the door, slipping on his shoes and grabbing his keys on the way. “We might as well head over there, then."

Apollo joined him shortly after, hopping along as he fought to get his shoes on. “Eh, sure. It's not like we've got anything else to do today."

Sol smirked slightly. “Did you decide that after Matt kicked your ass at Halo again?"

Apollo glared, making his brother laugh.

They both piled into the small Saab, and talked on the way to their destination. It was nonsensical conversation, mostly relating to guesses about what Matt was calling them for. When they arrived, they were surprised by what was awaiting them by the door -- a small, orange unicorn. It beamed upon spotting them approaching.

“Apollo! Sol!" The voice identified it as male. He approached and reared back to give them both a hug. “You made it!"

Sol blinked as he was hugged by a small mythological creature. “Uh... wait... Matt?!"

“Yup!"

Apollo found his mouth moving without even really thinking about it. “But... but... what?!"

Matt chuckled, then nodded to the store behind him. “This is the reason, as ridiculous as it sounds. Come on, I wanted to recommend you to --"

Sol gaped at him. “What do you mean, the store changed you?! Wha -- bu -- how?!"

Matt grinned. “Follow me and you'll find out." He paused at the door. “Oh, and I go by Muse Scroll now. Muse works, though. You'll understand soon enough."

Apollo sputtered, “I hope so! Going from human to small unicorn is a pretty drastic change!"

Matt -- no, Muse now, chuckled as he led the way into the store. The lady behind the counter in the center waved, smiling wide.

“Hello," she greeted. “My name is Jean. Muse has told me a bit about you two."

Sol frowned a bit. “What... about us?"

Jean shrugged. “Just that he thought you two would be good candidates for what we offer."

“And... what do you offer?" Apollo asked nervously. “To... turn people into ponies?"

Jean chuckled a bit. “Only if you want to be." She gestured to the rest of her shop, bringing Sol and Apollo's attention to the various costumes. “Or you can become what you see."

It was at that moment that what appeared to be a female, anthro, shiny Espeon walked out of the back area, dressed in jeans and a white shirt.

“Sol! Apollo!" The Espeon came forward and hugged them both, one at a time. “Muse finally dragged you in, huh? It's about time."

Apollo blinked at the sudden hug from the busty Espeon, blushing a bit -- then gasping a bit as he connected the dots, slightly recognizing the voice. “Wait... Kitora?!"

Kitora grinned as he stepped back. “That's me!"

Sol gaped for a moment. “So... wait... how did you..."

“Let me explain. Come on, there's a table and chairs over here."

Kitora led the two young men over to a table on the other side of the counter, where he gave them the story. Kitora made sure to point out his and Muse's protective bracelets, designed to only let those who are worthy of being changed see through the enchantments. The way the costumes merged with the wearer, but only became permanent at the wearer's choice. Or in Muse's case, the option to become what they know as a pony.

Apollo raised an eyebrow at Muse. “A pony? Seriously?"

Muse blushed a bit. “Shut up." His horn glowed for a second, after which Apollo yelped at how a big ball of paper smacked into his nose. “Besides, it lets me use magic."

Sol shook his head, still trying to believe what he'd been told. “If it weren't for the fact that you both were here as evidence, I... might be questioning my sanity."

Kitora chuckled. “I can't blame you, I had the same reaction at first. But, I'm not gonna lie, I've really grown into it."

Muse gave a smug smirk to his friend. “Yeah, we can hear that every night."

The faces of everyone, aside from Jean who just giggled, turned red. Kitora glared at Muse, who just laughed. At least until Kitora smirked.

“You're one to talk. I've had to get your and Skydancer's room soundproofed, remember?"

Muse blushed brightly, seen even more clearly through his orange coat, causing his friends to laugh. After they had calmed, Sol and Apollo looked at each other. A hidden secret between them was that they weren't truly brothers -- at least not by blood. And yet, they might as well have been, with how close they were. After a time, Sol gave a resigned sigh.

“Alright... we'll go for it."

Apollo took it up from where Sol left off. “But we'd rather do what Muse did, and... see what we'd become."

Jean nodded, coming over from behind the counter. Muse glanced over.

“Are they going to have their... forms read the way mine was?"

Jean giggled. “No, I have an easier way. Here." Jean reached behind the counter, and removed two small devices, that looked similar to what medical professionals now used to track a patient's pulse. “Just put these on. They'll feel a little strange, no more than if your hand had fallen asleep. But they'll find out what I need to know."

Apollo held out his left hand, with Sol offering his right. The devices were placed on their index fingers, and as promised, their hands went numb. It was certainly a strange feeling. They both had to fight the urge to shake their limbs awake, but thankfully the sensation only lasted a few moments. As soon as the devices beeped slightly, Jean removed them, and the brothers gave sighs of relief as their hands had feeling return to them.

Muse was about to ask what they thought would be the results, but they were interrupted by Jean's reaction. It was the first time that Muse or Kitora had seen Jean look so... shocked.

Sol wasn't sure he liked her expression. “Is... is something wrong?"

That seemed to snap Jean out of it. It took her a minute to decide on how to answer, but she opted to start by sighing. “No, nothing's wrong. It's just... well, Muse, where your kind comes from. Your current form, I mean." Muse blinked and looked himself over. “Equestria and all? Well, aside from the fact that you are one... it's real. I've been there, and their princesses have come here."

Muse stared at Jean, his mouth gaping as much as his friends' were. Jean nodded, sighing again.

“My employees... one of them can do prophecies. And there has not been a single failure." Jean looked Sol and Apollo in the eyes now. “And one of them was of you two, arriving to be the perfect ones."

Apollo frowned in confusion. “Perfect ones... for what?"

“For Celestia and Luna."

The brothers flinched slightly, the shock and surprise evident on their faces. Sol recovered first. “W-What do you --"

Jean held up a hand, silencing them. “Believe me, it's as strange for me as it is for you." She paused. “Well... maybe not, but... anyway. The prophecy was short, and actually rather sweet. Two beings from this world would come to be, and they would be the perfect ones for the Princesses Celestia and Luna."

There was a momentary silence.

“That's really freaking corny." Apollo blurted out after a few moments.

The group of them all took a second to let that sink in, before they all laughed. Once they calmed down, Jean spoke again.

“Yes, it is very corny. Yes, it sounded just as ridiculous back then as it does now. But it is also true. You'll see what I mean soon, boys."

Kitora gave her a confused look, something that had been done so many times within the past hour.

Jean gave a sort of half-smile. “The devices... if they found you, they would alert them, and they'd --"

As if on cue, there was a bright flash in the room. After it faded, two large ponies stood there. Two ponies that, if Sol and Apollo were to be honest when asked, caught their attention almost immediately. Sol's gaze locked on the tallest of the two, the pure white. Apollo's was on the dark-blue. Respectively, the large ponies were gazing at their respective men. There was... something attracting them to each other.

Jean smiled, and bowed to the tall ponies, her guests following suit shortly thereafter. “Princesses."

The white one snapped out of it first, rolling her eyes. “Jean, you know that's not necessary."

“I know, Your Majesty."

The blue one sighed. “Then you know that it annoys us."

Jean's smile widened visibly. “That's why I'm doing it, Princess Luna."

Luna's cheeks puffed out adorably, causing Jean to laugh as she straightened. Then she turned to her guests, as they straightened up as well.

“Boys... and herm," Jean commented, making Kitora blush when Sol and Apollo stared at him in surprise. She giggled. “These are the ponies I was talking about," gesturing to the tall white, “Princess Celestia," then pointing out the other, “and her sister, Princess Luna."

“Afternoon, boys," Celestia greeted politely, then her smile vanished as her tone turned deadpan. “Please, no honorifics. We get it often enough at home."

Muse chuckled. “Understood." He paused, giving Jean a slightly wicked grin, “Your Majesty."

Celestia groaned and promptly slapped a hoof into her forehead. Muse grinned up at her. One could almost see the glowing halo above his head.

Luna rolled her eyes, and turned to Apollo and Sol. “So... you two must be the ones that called us here."

Apollo swallowed, finding himself blushing despite only having just met the mare. “Yes. I'm Apollo."

Luna smiled and came forward, offering a hoof to shake. Apollo graciously grasped it, and with a spur of the moment decision, leaned down to give it a kiss. Luna found herself giving a little giggle and blushing slightly. Glancing to her side, she spotted Celestia being given a similar treatment from the other male.

Apollo followed her line of sight. “That's my brother, Sol."

Luna blinked in surprise. “Your brother?"

“Not by blood, but... yes."

Muse and Kitora, watching this take place, decided to take this as their cue to leave, and snuck out of the store. Once Jean had seen to their departure, she turned to the mares and the boys that were already chatting up two separate storms. She coughed, getting their attention. Jean had to force down a smile when all four of them jumped at the sudden interruption.

“As much as I'd love to have you four stay, I think you should... fulfill that prophecy at the boys' place," she suggested. She smiled when all four of them blushed.

Sol was, once again, the first to recover. “C'mon, Tia, we'll take you to our place."

Despite not really being one to be a fan of nicknames, somehow, when Sol said it, Celestia... actually liked it. The four of them moved from the store to the car, causing the mares to ask for help regarding securing themselves into the ride. After a few moments, they made their way to the boys' home. Luna found herself asking question after question regarding the many things that they passed by. Apollo took it in stride, answering them to the best of his ability. His favorite questions were undoubtedly the ones regarding the cars and other vehicles they passed. Sol enjoyed Celestia's question about the solar panels the most.

“They draw power from the sun?" Celestia questioned, getting Luna's attention as well. “How?"

Sol chuckled a bit at her curiosity. It had come just in time for them to reach the boys' apartment, where Sol had a set of panels up as a backup power source. Apollo rolled his eyes, but decided to stay with them to listen in, despite having heard it several times already.

After a while of listening, Luna turned to Apollo, giving him a look that said it all. He chuckled and led the way back inside, to his room, where Luna was attracted to his gaming setup. Especially his custom-built computer, which used some of its own solar panels as a way to power the fans and other minor items inside the tower, thus freeing up power for the other parts.

As the two of them talked about their choice of games, they unconsciously drew closer and closer to each other, to the point of touching. Neither of them moved away, nor did they acknowledge it beyond the way Luna wrapped her wing around Apollo. At least, not until Celestia caught their attention with a loud cough, making the two of them blush and back away.

“Aww!" Celestia grinned to her sister.

Luna glared through her red face. “No! Don't you dare, sister!"

“What about me?" Sol asked, with an equally tortuous grin.

Apollo glared just as much as Luna. “Sol, keep your mouth shut, or --"

“Or what, bro? You'll make out with Luna?"

Apollo's face darkened further and his mouth snapped shut. Luna glanced away, mumbling something under her breath.

Sol and Celestia shared knowing glances, and after a second, Celestia spoke next. “Well, we'll leave you two lovebirds to it."

As they walked off towards Sol's bedroom, Luna and Apollo could be heard simultaneously denying the accusation. Sol and Celestia chuckled, and went into the man's bedroom. Celestia smiled at the solar-based theme it bore, the way the sheets and pillows all had solar decals. It wasn't overwhelmingly designed as such, the way her own room was. There were several parts of it that showed appreciation for the night as well, such as a model moon that sat on Sol's dresser. Next to it sat a model sun, and they both spun from the three tubes blowing air on their bases.

Sol sat down on the edge of his bed, gesturing for Celestia to sit next to him, an invitation she happily accepted. “So, Tia, how long until those two are at it?"

Celestia blushed a bit and glowered at him. “That's my sister you're talking about."

“It's also my brother that I'm talking about."

Celestia glowered at him for a bit longer, then giggled. “I'm betting that it'll take less than ten minutes."

“Then I'll bet more than ten minutes."

“Oh?" Tia gave him a sly grin. “And if I win...?"

Sol blushed a bit. “You get to... do anything you wish to me."

“Anything, hmm?" Tia leaned in and breathed hot air on Sol's exposed neck, making him shiver slightly and gasp.

“A-Anything... but not until then."

Tia smirked. “You're on. But what shall we do until then, hmm?"

Sol grinned. “Gossip about our respective worlds, of --"

It was at that exact moment that Luna decided to interrupt, all the way from Apollo's room. She cried about him “keeping going" and that “she was getting close", making both Sol and Celestia blush. Although Celestia did grin rather smugly.

“Hm. Looks like I win, my dear," she whispered hotly, leaning in close to Sol's face. “So I claim my prize."

Sol swallowed slightly. Despite having just met, he could already tell how much he wanted her -- just as much as she wanted him. “A-And what will you have me do?"

“Strip. I want you naked."

Sol chuckled nervously, but did as he was told. As a way to torture Celestia, he decided to take it slowly, starting with his upper body clothes. He didn't get much farther once his shirt was off, however; apparently the sight of seeing him reveal his well-toned muscles was too much for Celestia, for she pounced upon him and mashed their lips together. She didn't even realize she was doing it, but upon their lips making contact, she was unconsciously pouring magic into her lips. Almost instantly, fur, clean white fur burst into being around Sol's lips. His jaw also started to slowly push out.

Sol noticed immediately, and in his panic, shoved Celestia away. She looked hurt -- at least until she saw what had happened, and blushed.

“C-Celestia?" Sol stammered. “Wh-wha..."

Celestia stepped back. “Sorry, I... I almost forgot a part of the prophecy that we were told."

“What?"

“That... that... you boys would join us forever, back in our world."

Sol poked at the way his jaw was now stretched, the way fur covered a small area around his lips. “And to do that, I'd..."

“Yes."

“I... I see."

“...I'm sorry, we should have led with that warning first. “

Sol didn't say anything for a time. He poked and prodded at his burgeoning lips, feeling out just how smooth and soft his new fur was. He could feel where it was already starting to spread, directly around that area. When he finally looked up at Celestia, his heart sank.

She was avoiding eye contact with him, shuffling her hooves nervously as she waited for his decision. Despite her attempts to do so, the worry for his reaction danced on her face. Sol sighed softly, reached forward, then pulled her back into the kiss. Despite his nerves, considering how they'd more or less just met, there was something inside his heart and mind telling him that this was the right choice. Instinct? A good feeling?

Well, whatever it was, Sol felt very attracted to this mare. That feeling swelled as their lips met, and he felt her magic seep into him again.

Celestia found herself shocked - at least at first. Then she melted into the kiss, returning in kind. She could feel her magic moving from her and into Sol's body on its own. And she had neither the means, nor the desire, to stop it. His mouth immediately resumed stretching out into a muzzle. (His brain quietly realized that the rest of his clothes had been magically removed from him.)

For a moment, panic thundered through Sol's veins at the change; but then it was replaced with a warm, powerful sense of pure pleasure. From the way Celestia moaned into his mouth, it seems she felt the same.

Sol could feel his hands rapidly clenching together. Something hard was starting to coat them, force them together. His hands very rapidly tightened into large, pitch-black hooves. White fur bloomed and around his wrists, sitting over the newly-grown hooves. As the fur traveled further up his arms, Sol could feel his muscles tensing. They spasmed lightly as they rapidly bulked, forcing a lot of tension on his skin. Then it immediately felt better as the magic washed over him.

Celestia finally pulled back from the kiss. That magnificent, wonderful caress that was just growing so intense. She gave him a look over.

“Oh... oh my."

Sol looked himself over. “What?"

“Your hooves look beautiful."

Sol looked again, paying better attention this time. “They're... very large."

“Yes. Yes they are." Celestia gently took one in her hooves. Sol gasped a little at just how warm she felt. Then she leaned down and kissed his forelegs, making him groan a bit. “And extra sensitive, just like mine."

“C-Celestia?"

She glanced up from where she was brushing his growing fur. “Yes?"

“Shut up and kiss me more."

Celestia giggled and did so. This time, however, she flared her horn, highlighting the bed that Sol was sitting on. Then she pushed him against it. For a moment, he felt worried; would his bed be able to handle all the weight? But then it turned out his worry was for naught. Whatever spell Celestia had cast, it made his bed handle all their weight perfectly. While he was distracted, she'd used another quick spell to put all her regalia off to the side.

As the kiss resumed - this time far, far more passionate - Celestia was given quite a surprise. Sol's new muzzle had finally finished growing in. And it was bigger than hers. Despite her dominant position, Celestia found herself on the receiving end of the kiss. Sol found himself pushing his changed tongue into her mouth. With a lustful whimper, Celestia allowed him in.

Her hind legs were braced against the end of the bed as the lovers continued making out. As it continued to grow more and more passionate, Celestia let her hooves and legs rub Sol's neck and head. The contact immediately forced everything to transform. Each second of transformation that passed made their kiss more and more passionate, more and more messy.

Sol felt his neck lengthening. Heat blossomed in his chest as Celestia lowered herself to be ever closer. Fur was started to grow all over his body... except for his crotch. His feet clenched, almost painfully, as the hooves started to take shape. They were just as large as his front hooves. The biggest difference was that his ankles, unlike his wrists, were rapidly forced further up his leg.

At last, the two lovers pulled apart.

Celestia gave him another look over. “Oh my."

Sol had to take a few moments to blink and regather his wits. His eyes - now colored a deep, rich, royal purple - had rapidly grown in size to match Celestia's. Once his muzzle had grown in, and his neck had started to be affected, had met in the middle. His hair was already long-gone by this point, but his mane had yet to grow in its place.

Finally he managed to speak. “W-What?"

Celestia didn't say anything. She was too busy admiring his changing body. Dear Me, I want him. I need him.

Her magic - no, it wasn't her magic anymore. This was simply Magic. And it was singing in her veins, her mind, her heart. Sol was very, very rapidly becoming quite attractive to her. She could tell just from his large hooves that he was going to be larger than her once he was done shifting. A distant part of her logical mind told her to slow down; to take her time in getting to know this stud.

Celestia ignored it. That Magic swelled in her heart (making her horn and mane and tail glow in the process) and it took her lust with it. There was a momentary flash from her horn again, highlighting the walls of the room, instantly soundproofing it.

It wasn't until Sol started to stand up from the bed that she realized that her body had moved. She stole a glance at his body mirror, the one hanging from his closed door. She spotted herself, standing in front of him with wings slightly spread, tail hiked up and moved to the side.

Oh Gods, Celestia thought. I presented myself without thinking about it... she felt a shudder run up and down her spine. Because it was only at that moment that she realized just how much her pussy was dripping and winking. Fuck, I want him.

While Celestia's mind and heart were playing catch-up with her body and instincts, Sol was focused on his own body. He was busy noticing that his shoulders, and pectorals, had broadened considerably. Not to mention all of the tightly-packed, powerful muscles that were stretching his body. Sol was starting to feel like he could bench press his car without issues. He hadn't noticed Celestia's movement just yet. Instead, he focused on moving his still-growing neck. A grunt escaped his now-equine lips as he felt his neck muscles bulge. Looking down at the base of his neck, he groaned softly as he watched his collarbone press further outward. The muscles there tensed, relaxed, tensed... and repeated in rapid succession until they were visibly rippling under his taut flesh.

His mind was giving very, very dim alarm sounds to how much his body was changing; he didn't care. He grunted again as his shoulders gave a sudden, sharp tug. They did it a second time, a third. Only then did his fully-transformed front legs have a new resting position. His ears - now resting atop his head as fully equine ears - twitched forward as he groaned again. His legs were being forced into a quadruped position, to match his front legs. Pure white fur blazed a trail up from his hooves. Beneath all his magnificently soft fur, the muscles and bones were being force-fed magic. Magic which forced everything to just grow bigger, stronger, more powerful.

Sol gave a sharp, loud grunt (he failed to notice that his voice had dropped a couple octaves) when his lower back and hips gave a sharp crack. The logic center of his brain realized that he was now stuck as a quadruped; his horny, lust-addled mind was too busy to care.

Then, and only then, did he notice that Celestia's weight was no longer on top of him. He looked up and found her slowly turning around. Slowly, sensually presenting herself to him. His tongue slipped out and licked his lips as he watched, taking in every single detail.

The Magic surged and planted a thought in his mind: Memorize this. Memorize how this mare looks to you. Memorize her smell, her appearance... memorize just how much you want her.

Memorize that she is yours. And that you are hers.

Sol was starting to stand up before he knew what he was doing. It was a bit of a struggle, given how unfamiliar he was with his new limbs, but once he managed it, it felt glorious. The sensation of his new muscles carrying his growing weight and mass with such ease was wonderful... but none of it mattered to him. Nothing mattered except his need to

claim

her.

Celestia stood there and watched. She watched with awe, with desire, with need. Everytime he made a sound, his voice gradually grew deeper and deeper, until it struck a chord deep within her. Just hearing his voice made her clit wink. (She would later realize that it wasn't his voice, but rather her magic resonating with The Magic that was so focused on Sol.)

When Sol stepped up closer to her backside, she spread her hindlegs just a little bit further apart. She lowered her front legs just a tad, preparing for the incoming weight. She closed her eyes for it, too; it would help her focus on the sensations rather than just the visuals.

It didn't happen when she expected. Confused, Celestia almost looked again -- but then her eyes snapped open when she felt his breath on her lips. Shivers danced up and down her spine, just from the way he leaned in close and took in her smell. She could feel every single exhale and inhale, the way it all brushed over her winking clit and pussy; the way each puff of air moved her juices around, making her whimper and moan.

Then her eyes rolled into her head when his tongue snaked out and tasted her. Her mind went blank. It wasn't a climax, not quite yet. But it wasn't far off.

For Sol, her smell and taste were intoxicating. The wonderful scent wafted over him, into his nose and watered his palette... and the magic grabbed a hold of it. It took that smell, and shoved it deep into his mind. There it sat, with a single, permanent title: “Your Mare. Yours." Sol hadn't been thinking clearly for a while now, but the magic allowed him a single clear thought:

I want to taste her.

So he did. He let his large tongue slip out of his muzzle, and licked the juices drooling out of her pussy. The taste and sensation burrowed deep into his mind, right next to the memory of her scent. His ears picked up the sound of her moans as he continued to lick. He dug his tongue into her, pushing his nose and muzzle right up against her.

Gods she tastes and smells so fucking good.

Celestia moaned as Sol buried his muzzle into her vagina. His chin pressed against her winking clit, sending fireworks of extreme pleasure through her. It just felt so good... and then his tongue managed to brush against her spot.

With a strangled gasp, Celestia came. Her breath left her. She couldn't say, do, or think anything right now. She didn't realize it, but her tail had stiffened. Her magic, and The Magic fueling the transformation, rendered the normally moving tail still. It sat directly on Sol's head and neck. (Distantly she felt a mane growing out from under her tail.)

Sol somewhat noticed the sensation of something growing out of his neck and head. But he was too busy with enjoying his lover's cunt. Feeling her clit press against his chin, the way she squeezed his muzzle, and the wondrous sensation of her juices coating his face... and just how mesmerizing her taste was.

After what seemed like an eternity (but was definitely not long enough), Celestia's very strong walls allowed Sol to pull away. It was only then that he became aware of how far along he was.

The fur had managed to slowly spread down his chest, forcing it to slowly expand into a large, imposing barrel. He didn't feel, or even notice, any discomfort when his organs shifted and grew to accommodate. But further down his body... his crotch sat completely untouched. His very, very human (painfully stiff and erect) cock and balls sat there. A very odd juxtaposition against the equine body surrounding it. He could feel something stretching out above his ass. A small little dock for his growing tail.

Celestia's orgasm had cleared both their minds. Celestia's mind was cleared just from the pleasure alone. Sol's was cleared from enjoying the wonderful taste and scent. It lasted just long enough for Sol to take stock of how his body looked and felt.

I... I feel so powerful. Tall. Strong. He looked back at Celestia. She was looking at him over her shoulder. Her eyes held a glazed look to them; a lost, pleasure-addled expression on her face. Gods I want her.

And from the look on Celestia's face, she wanted him just as much.

The next thing he knew, Sol was mounting her properly. Celestia gasped at the sudden weight on her back, but since she'd braced for it, she managed to keep from falling. Sol allowed instinct to take over. It guided him further forward on her back, drove him to hump slowly, desperately searching for her opening.

At last, he penetrated her. For Celestia, it felt mildly satisfying. For Sol, it was good, but there was much left to be desired. Even when he managed to push the rest of his cock into her, they both wanted more.

Sol continued to very slowly thrust into Celestia. Below him, Celestia closed her eyes and focused on the sensations flooding her body. Admittedly it wasn't very satisfying. She could feel his penis inside her, but it was just... so small.

Thankfully, however, The Magic acted fast.

As a human, Sol had been blessed with a decently sized cock, and generously full balls. As an equine? They were small. Seconds later, however, they both gasped and groaned as this changed.

Magic seeped from his full-grown tail into his asshole, forcefully dragging it further up to where it belonged. In the process, Sol felt it grow plump, tight, and mildly sensitive. He felt the magic drag down his taint, drawing the skin taut. Everything around his crotch grew, as well. (Later on, he'd notice that his ass was quite large, and packed full of extremely powerful muscle beneath a layer of deliciously soft fat.)

The Magic moved itself down to his cock and balls. They very rapidly pulled his cock a bit further away from his balls, dragging his sack a bit further up his taint and letting them sit there. Then there was a very sudden surge of Magic. Instantly, his human balls fired every single drop of human seed. Sol gasped slightly as it happened.

Then his cock started to change. His balls were rapidly filling with Magic-laced seed, and with each thrust into Celestia, Sol felt his balls clench and fire a small shot of cum into her. They felt nice, but they weren't quite the climax he wanted. Instead, both Sol and Celestia focused on what each one did to him.

First and foremost, his testicles swelled like cum-filled water balloons. Steadily growing, forcing his sack to grow taut and its flesh to get thicker and thicker, just to contain his balls. As they filled, Sol groaned at how heavy they were becoming. Below him, Celestia gasped and moaned with each thrust, for his ballsack was smacking into her winking clit each time.

Second, the foreskin of his dick was pushed back, letting his dickhead rub directly against Celestia's velvety walls. (Sol gave a lust-fueled snort as he felt it.) His foreskin kept getting pushed further and further back, forcing all of the skin to bunch up at the base, forming a large sheath. In the process, his cock seemed to grow thicker and even more stiff... and it felt like something was pushing forward.

(If either of them could see it, they might have been disturbed by the sight.)

It pushed up through the opening at the tip of his penis. It was spread open wider and wider, slowly forcing something out of the end of his dick. There was a soft pop (or there would have been if they could hear it) when a large, flared tip freed itself from his human glans. It forced itself further and further into Celestia's cunt, growing thicker and denser with every thrust.

Sol was having to put in semi-conscious effort just to breathe. His old human glans had been moved towards the middle of his growing horsecock; it now fulfilled the purpose of his very sensitive medial ring. Feeling it go in and out of Celestia's pussy was divine.

Celestia had no idea about what Sol was feeling from his perspective. Instead, she was focused on just how much bigger he was getting; how he was growing more and more satisfying. More than that, the rest of his body was still growing a bit as well. She was forced to spread her legs wider; to engage the Earth Pony portion of her Alicorn powers in order to simply stay standing.

The moment she did, Celestia's eyes widened in pleasured shock. Sol's cock was now brushing against her spot with every single movement. An instant later, she came. Her pussy squeezed his penis; her cum squirted against his inner thighs and landed all over the floor.

But that apparently wasn't enough; in the middle of her second climax of the night, Celestia managed a soft, strangled whinny when Sol's newly formed horsecock hit her cervix. In addition, his girth was starting to stretch and fill her more than... than... well, more than any other time in her entire life.

Sol was, on some level, deeply pleased that he'd managed to get his mare to cum so hard; he was equally proud that he was able to fill her so much, so wondrously. He felt her wings flutter a bit around his large barrel, slapping his back. Instantly, two very large, feathery wings erupted out of his back.

The Magic (the self-powering, semi-sentient Magic that fueled everything occurring tonight) flowed up his wings. As each iota of Magic touched his feathers, Sol felt himself becoming desperate to reach his peak. His thrusts rapidly grew more and more forceful, more and more powerful. His wing muscles grew larger, stronger, more resilient. Celestia's wings brushed against his. All of those sensitive nerves sent so much pleasure from the contact; it helped that both Sol and Celestia were much, much warmer than a human was. Once his wings had finished growing in, The Magic rushed for Sol's forehead.

There was a split second of lucidity for Sol when it dug into his head, into his mind.

Oh shit, what's happe-

And then his horn erupted out of his skull. Out was instantly at it's full length, nearly a foot long. In that very instant, his horn touched Celestia's. And The Magic gave one last experience.

For a moment... just one, memorable, magnificent moment...

The souls of Celestia and Sol were laid bare for each other. They saw each other in their pure, true forms; two Alicorns, whose bodies and minds and souls, were forever linked. They witnessed each other's strengths. Weaknesses. Flaws. Regrets. Everything.

And in that instant, they fell deeply in love. A love that burned as brightly as the suns that sat on their flanks.

The Magic faded away, allowing them to return to their bodies. It forced itself into Sol, through his horn, and claiming him as its master for the rest of his life.

Sol came. Celestia, for the third time that afternoon, came with him.

She was left reeling at just how much he was filling her, and so forcefully. His heavily-flared cock was pressed right up against her cervix, forcing it open to receive every drop of his gloriously thick, hot seed. Sol belatedly realized that at some point during their soulsight, he had leaned down and tightly clamped his teeth around the base of her neck.

It took several minutes for their mutual climax to die down. During that time, lucidity and self-control gradually returned to them.

Celestia spoke first. “Ho... holy fuck..." She was panting heavily, desperate to get her breath back. “Sol... Sol, my beloved..."

Sol blinked his eyes open. "Mm?" He had yet to stop biting her neck.

"Take... Take a look at yourself."

“Mmf... do... do I have to?" To emphasize his point, Sol pressed against her. Both of them shuddered from just how good it felt.

Celestia took her resurging lust and shoved it back. “Yes. Please."

Sol didn't want to. He really, really didn't want to pull out of his mare. But she'd asked nicely. So with considerable effort, he forced himself to pull himself free of her velvety walls. Celestia bit her lip to keep from whining about it; she failed, though, as a soft whine escaped her. Luckily enough, Sol was a bit too busy to really hear it.

Once he was free, Sol stumbled on his new legs for a moment. Thankfully newly ingrained instincts helped him keep from falling over. Sol stepped around Celestia to stand at her side, and finally looked into the mirror.

“I... wow..."

Celestia giggled and nuzzled him. “You are incredibly handsome, Sol."

And he really, really was. Now that he was a full-grown alicorn stallion, he stood over a head taller than Celestia, and his new body bore much more muscle. His much bigger eyes held a deep, royal purple; overlooking a large, block-ish muzzle that somehow managed to still look very regal. On his chin was a small tuft of extra fur, almost looking like a well-groomed goatee.

His new mane and tail were constantly in motion, the same way Celestia's were. His colors were very similar, too. Except for the fact that his were colored several shades darker. If her mane represented the early morning rays from the sun, his were more like the rays from around noon.

Sol crossed his eyes a bit as he looked up at his foot-long horn. It started a soft, pristine white at the base. But it rapidly transition into a warm orange at the tip. His wings were very similar. Except the color gradient was tilted to grow more orange-red towards the ends of his wings.

Celestia was still nuzzling his neck, kissing his collarbone on occasion. Sol murmured softly everytime. Eventually his curiosity got the better of him, and he started moving to look under himself.

“No." Celestia used a wing to stop him. “Don't look just yet, love."

Sol blinked at her, but didn't argue when she kissed him deeply.

“Close your eyes."

He closed his eyes. She gently, firmly, pushed him back towards his bed. Sol felt his hardening cock bouncing on his belly, splattering his underside with precum. Celestia used her magic to make Sol lay on his back.

“Alright, Sol. Now you can look."

Sol slowly opened his eyes. Celestia had her muzzle very close to his balls, where she was eyeing his cock with a predatory hunger that sent shivers up his spine. Then he noticed just how big he was. His jaw dropped open.

He was at least a foot long, and a minimum of an inch and a half thick. His balls were about the size of the average tennis ball.

“Mm, that's right, my stallion. You are big." She paused to lean down and kiss his left testicle, making him moan. “Bigger than any stallion I've ever fucked. And you are mine."

“C-Celestia, w-wait... I just...!"

She giggled a bit. “Oh my love. You don't have to worry about being sore or running dry. You're an alicorn, now, after all. Trust me. You will never experience either of those ever again."

Then she stepped onto the bed and pushed his entire length into her throat.

Sol laid back. He decided to simply enjoy all of the sex that was about to happen.

Meanwhile, in Apollo's room. Right about the time when Celestia and Sol started kissing.

“Keep going! We're almost there!"

Luna grimaced when she glanced at her character's health. “Almost... almost...!"

An instant later, VICTORY flashed across the screen. Apollo pumped his fist. Luna hugged him.

“Yes! Awesome fight, Luna!"

She was grinning wide. “You were pretty epic yourself, Pol."

He blushed a bit. “Pol?"

She gave him a mildly half-lidded look. (He had yet to notice that her contact was making deep, midnight-blue fur erupt all over his body.) “Yes. Pol. Is that a problem?"

“Uh... no...?"

“Good."

Luna leaned in close and kissed him deeply. His muzzle immediately started to grow in, pushing against her lips. A groan escaped him as his body was very rapidly shapeshifting to a more equine build. When she started to try to push him onto his back, Apollo pushed her away.

“L-Luna... wh-what's...?"

Luna gave him a soft, warm, loving smile. It made his heart flutter at just how beautiful she now looked. “Apollo. I will explain, I promise. But first." Her horn lit up. “Tell me honestly. Do you want to stop?"

“Wh-What do you mean?"

“I'm going to pin you down and fuck you, Apollo. Do you want me to stop?"

His heart skipped a few beats. He knew his answer instantly: no. He didn't want that to stop. Something inside his mind, his heart, told him not to, and he listened to it.

But rather than wait, instead he leaned forward, and pushed Luna onto her back. She gasped in surprise, then moaned when he pushed his growing tongue into her mouth. When he pushed her onto her back, she didn't resist. Instead, Luna wrapped her legs around Apollo and pulled him close. Her horn flashed a bright blue for a few seconds.

Apollo pulled back when he noticed that his clothes had suddenly vanished from him, and that it seemed like he couldn't hear anything from outside of his room.

“Luna? Did you...?"

She nodded. “Removed your clothes. Soundproofed the room. Reinforced your bed." Then she grinned. “Now prepare thyself, Apollo."

Apollo had a second to wonder what she meant, but then he found himself levitated onto his bed, leaning against the headboard to sit up. Luna planted her face at his crotch and immediately started to lick his rapidly swelling balls. His cock wasn't far behind, especially as she dragged her tongue from the underside of his scrotum, all the way to the tip of his penis.

Unlike Sol's change, his was far less drastic. For Apollo, he was granted the chance to watch as everything simply became... more.

Every time Luna slid her tongue against his cock, suckled on his enlargening testicles, or suckled on his widening tip, his hips bucked slightly. His human seed was being emptied with each thrust.

“L-Luna... I-I'm close..."

Apollo was, indeed, very close. Close to cumming, and close to having his genitals finish changing. His new tail was growing in, too. Luna hummed softly, closed her eyes, and wrapped her lips around his cock. Then she slowly, ever so slowly, pushed the rest of his fully-grown horsecock into her throat.

The instant Apollo's new medial ring passed her mouth, where she suckled on it, he came. And he came hard.

Luna's muffled moans of euphoria only served to heighten his climax.

When, at last, he finished, she took a moment to pull off of his cock with a soft pop. He watched as she took another few moments to swallow all of the cum that she'd had pumped into her throat.

“Mm. You taste so wonderful, Apollo." Luna moved further up his rapidly changing body.

While he was being given the best (and first) blowjob of his life, Apollo's body had transformed. Very, very rapidly. The Magic, at first fueled by Luna's own magic but now fueling and controlling itself, had made him into an alicorn already. His chest was still barreling out, filling with improved inner organs and massively powerful muscles. His hindquarters were fairly slim, like Luna's, but Apollo's were filled with more tightly packed powerful muscle.

The Magic, however, noticed where Luna was going with this. So when she started to kiss Apollo sloppily, making their tongues wrestle, it moved up towards his growing mane.

When she, in her lust, pushed Apollo's cum-soaked cock into her winking pussy, The Magic moved on to making his wings grow.

Apollo grunted and moaned with Luna as she started to ride him. He did his best to match her bucks with thrusts of his own, but the sensation of wings bursting from his back was rather distracting.

“F-Fuck, Luna... I... I'm not gonna last long..."

Luna didn't say anything. She just leaned down and kissed him again. Harder and wetter than before. Magic surged through Apollo, to his forehead. His horn rose out of his forehead in a split second, made contact with Luna's.

And just like with Sol and Celestia, Apollo and Luna were granted the privilege to see each other's souls. No secrets hidden, everything was laid bare for them to see.

Luna saw Apollo for who he truly was; Apollo saw Luna for everything that made her who she was...

And they both fell in love. Their love grew deep, deep as the ocean their moons moved.

When they returned to reality, the ponies found themselves gasping for air. Recovering from another, powerful, mutual climax.

Apollo didn't even hesitate. He used his new strength to force Luna onto her back below him, and immediately started fucking her.

Many, many days went by before they returned to that “costume" store. There, Jean was giving Apollo and Sol a knowing smirk. Both of the alicorns stallions stood in front of her. Sol was blushing a bit and shuffling his draft horse sized hooves; Apollo wasn't really all that embarrassed.

After a few minutes, Jean finally giggled. “You boys must really love those mares to move to their world, hm?"

Apollo gave a bit of a dopey smile. “Yes..."

“Well, don't worry about your home. The girls have arranged a deal with me and my family to keep your home in good condition." She held up her hand to stop any incoming disagreements from them. “The deal has already been made, contract signed and everything. And trust me, they won't take no for an answer. Your home will be taken care of. It'll make a good vacation home for you all, anyway."

“Uh, right..." Sol took a deep breath. “Okay. So. Um. They're coming to collect us soon."

“We already said bye to our friends..." Apollo mentioned. “And you've already helped us make sure we'll be able to stay in contact reliably. Thank you for that, by the way."

Jean smiled. “You're welcome."

There was a sudden flash of light. It faded away rapidly enough, and the instant it was gone, both of the stallions found themselves distracted with kissing their lovers. Moments later, the flash returned.

When it faded a second time, the stallions found themselves in a large castle. Canterlot Castle.

Their new home.
