Her radiant dawn
You wiped your brow; The constant beating of the midday sun a constant reminder that you aren't yet used to this climate, and fuelling the niggling desire to simply not wear clothes. You knew the residents wouldn't mind, but it still felt wrong, like throwing off the last of your humanity. Maybe it was time, but you still had hope you could return home one day.
Not that Equestria was by any means a bad place to live, the warm climate and friendly natives had made your unfortunate summoning comfortable, at least, but so far the town's purple mage had yet to figure out how to reverse her spell. She was truly sorry, though, you could tell she was being honest, and at least she'd tried her best to get you integrated into the town, letting you stay at the library and helping you get work as a handyman around town.
Suddenly, with a bright flash, Twilight Sparkle appeared before you, bringing with her the light scent of freshly cut lavender, mixed with the decidedly less attractive musk of stress and exertion. "Hide!", Twilight screeched, pouncing at you and pushing you behind a nearby building, "Celestia is sending the guards! For you!"
Pushing the shock of her cute purple body's proximity out of your mind, and shooing away the easy fantasies of her taking you there and then, you asked her what she meant. "I just got a letter, she's summoning you to the castle! There are dungeons in the castle!", Twilight screeched at you.
Twilight's friends had warned you about her when you first moved in, so you knew about her tendency to overreact. Something else you knew, from talking to Twilight herself, was that the dungeons were ceremonial and had never actually been used; Something you took great care in gently reminding her. "I... but... there's a first time for everything!" squeaked Twilight with clear uncertainty in her voice. The two of you lay there in silence, with her body pressing against yours and her frantic breathing echoing in your ears. Eventually, she looked away and shuffled off of you, helping you up with a magical push.
"I'm sorry, you're right, Celestia wouldn't do that. At least she's never done it before. But you've never been here before either!", Twilight struggled, her concern and fear for you touching, albeit worrying. After much patience, Twilight eventually calmed down, accepting that you probably weren't about to be hauled away, and that if you were, Celestia probably had a good reason. Fetching the scroll in a flash of light, Twilight began to read it out to you.
"Dear my most faithful student, Twilight Sparkle,
Please inform your human guest that I wish to speak with him immediately, and am dispatching the guards as you receive this letter. This is a matter of urgency and must be dealt with quickly.
Your tutor and princess, Celestia"
According to Twilight, it took an unburdened Pegasus about an hour to fly between Canterlot and Ponyville on average, but the guards would be bringing a carriage. In any case, Twilight had fretted about it for long enough that they could turn up any moment now - and you haven't packed a thing!
Rushing back to Twilight's treehouse, the two of you burst through the door just in time to find Spike setting your bags down. "Oh, hey guys, we're all packed! I can't wait to see Canterlot again, I love that place!"
"Uh, Spike?", Twilight started, "We're not going. Just him. You did read the letter, didn't you?"
Spike's face fell as he fell onto his backside. "I kinda skimmed it", he admitted, "Can we go anyway?"
Twilight laughed nervously, and opened her mouth to explain to Spike they couldn't go when there was a knock at the door. Three strong, timed raps on the hard wooden door - the calling card of the Equestrian Guard.
"Ah, Hello Miss Sparkle. Is he here?" the nondescript white Pegasus inquired as Twilight swung the door open for him. She nodded her head in your direction. "Come with me", the guard demanded, proving what Twilight had told you at some point - there are no lessons in tact in their training.
Following the armoured equine outside, you saw his white, wooden carriage resting carefully on the ground. There was no barrier on the end. You hoped your escort was planning to walk back, but something told you that was in vain. Twilight carefully lifted your bags into the carriage while Spike sat inside moping, muttering to himself about how he never gets to go anywhere fun. You promised to bring him back something nice, if you could. Twilight gave you a sad stare.
"Right, get in and we can be back cityside by sundown", the guard barked, hooking the carriage into his armour and flaring his wings. You jumped up, huddling at the end of the too-exposed chariot as the pilot started to gallop down the dirt path, building up speed and jostling you about as the wheels rocked against the uneven ground. As the guard started to beat his wings, you watched Ponyville become smaller and smaller below you, until you could no longer pick out the image of Twilight's waving hoof and worried face.
After the initial ascent up to Canterlot's height, the flight was luckily quite stable, and you somehow managed to not fall to your death. The extra weight meant your flight took most of the remaining day, but Spike had packed you a book. Much as Twilight's worries seemed over the top, seeing the book, and how much they cared for you, made even the slightest chance of not coming back twinge in your heart. You had friends there.
You tried your best to lose yourself in the book - a tome of Equestrian myths and legends - as the strong winds blew around you, but eventually gave up and just watched the countryside fly past, occasionally looking over the guard's shoulder to the grand capital city of Equestria, Canterlot. You'd never been, both Twilight and Celestia had agreed that it would be best for you to not move around too much.
Eventually, you touched down, just outside of the royal castle. "Go on ahead, sir, the princess is expecting you", the guard commanded, pointing over to a nearby entrance before unhooking himself and starting to clean his carriage. You followed his instruction, grabbing your back and slinging it over your shoulder as you made your way into the castle, marvelling at the architecture and trying not to look down as you walked over the thin bridge between the landing pad and the castle grounds; It was a long way down.
The doors swung open as you approached them, the two guards bowing their heads as you passed. Celestia, it seemed, was expecting you. After asking one of the guards how to get to the throne room, you set on your way, walking through the large (Unthinkably huge in pony terms, but you're taller) corridors and being wowed by the lavish decorations and opulent surroundings. Compared to the rustic charms of Ponyville, this seemed absurd, Celestia certainly was living the life of a princess.
Walking through into the truly gargantuan, even at your scales, throne room, you spotted Celestia standing at the end, idly gazing out of a window, the setting sun streaming through, silhouetting her body and illuminating her mane, burning a vision of beauty into your retinas as you found it difficult to look away. You had to fight the compulsion to kneel before her as you screwed up your eyes and looked away, still seeing her figure on your eyelids, until it eventually faded.
When you opened your eyes again, Celestia had noticed your presence and walked closer, standing a few meters away from you. Her mane flowed freely, as if by invisible winds, and everything behind her semitransparent hairs was somewhat blurry. She was about as tall as you, if you didn't count the horn, a good foot taller if you did. Her long, thin legs elegantly hid the pure muscle powering her strong movements, and her huge, white wings were folded at her sides.
She was beautiful. The sort of drop-dead gorgeous that simply didn't exist. A completely perfect figure, without imperfection or flaw, her fur completely clean and well kept, and her eyes just the right mix of caring and commanding, giving off a regal air. You knelt, in the presence of a god, and bowed your head in reverence. No wonder there was so little dissent in Equestria, when most of the population had laid eyes on this figure of perfection.
She laughed quietly, the soft sounds washing over your ears like the sweetest musics and echoing around the hall, reverberating back upon you to create an incomparable symphony. "There's no need to kneel, my dear, you aren't one of my subjects. Come, stand, we have much to discuss", she said, her voice almost like a song, betraying no irritation or annoyance; just oozing confidence and resonating with a calm, but powerful tone. You complied, standing up and walking behind her as she made her way back to her throne, pulling up a rather less magnificent chair for you to sit on.
"I can get you home.", she stated, leaving the sentence hanging in the air for you to fully comprehend it, "if you want to go. Our worlds will be close enough to push you back through until between dawn and dusk tomorrow, but I do not know when that will happen again. I won't make you do anything you don't want to, and I understand it's a lot to think about. I've prepared a room for you, if you wish to, ah, 'sleep on it'"
Apparently Twilight really did tell Celestia everything, including your attempts to introduce some human phrases into their vocabularies.
You accepted her offer, and thanked her for the room, but your mind was elsewhere: Home. You could go home. Everything you'd missed, from places, to food, to music, and most of all people, you could see again. Tomorrow. It was a lot to take in; you'd never expected to return home at all, really, not after so long. Your mind thought back to Celestia's words - "it's a lot to think about" - and pondered them. It was, Equestria really wasn't so bad. You had friends here, some almost as good as family. You had a life, with hopes, and aspirations; nothing fancy, but a happy life all the same. Perhaps Celestia was right, perhaps you should sleep on it.
The bed was soft and luxurious, a large (especially by your standards), comfortable mattress supporting your weight and a thick, silky duvet covering your body. You'd heard tales that Celestia's beds were made of donated Pegasus feathers, but you'd never believed it before now. Falling asleep was effortless, and you were quickly slumbering away as the day's sun set behind the distant mountains and started to prepare to rise again, for what could be your last sunset.
Your sleep was so refreshing, in fact, that you woke up some hours later feeling as if you'd slept for days, when in fact dawn was still a distant future event. You got up, you had thinking to do anyway. Walking over to the glass doors and looking out onto the balcony outside, and from there down the mountain Canterlot rested on to the countryside and scattered villages below. Celestia could see practically her whole kingdom from here, it was no wonder she had chosen this place.
Going to your bag and pulling out the woolly coat Spike had thoughtfully packed, you clothed yourself and opened the doors, wanting to gaze out across Equestria. You didn't know whether you wanted to leave, but you knew it was a beautiful place that you would regret not seeing. Stepping out onto the balcony, you breathed in the cold night air, and took in the sights. It was silent, save for the wind, this high up, giving the whole scene an eerie beauty, like looking into a snowglobe.
A quiet sound drifted through on the wind, drawing your attention rightwards, along the castle to the next balcony along. Celestia stood there, her daytime glory faded in the darkness of night, but it still left her no less awe-inspiring than the landscape around you. The sound was a sigh, and her face was not a happy one as she too stared across her lands. Her hair flowed freely in the wind, whipping around her neck erratically as she made no effort to control it.
"Princess?", you called, trying to keep your tone to a mixture of respect and concern. She snapped her head around, reigning in her mane back to its normal slow flow as she turned, but let it fall back to her side when she saw it was you.
"Oh, I had forgotten your accommodation was so close to my own. My apologies for the interruption" she said with her practiced, perfect voice, not revealing the tiniest slither of any true emotions. Well, you figured, you were going home forever tomorrow anyway, so what's the worst that can happen? You asked her outright whether she was okay, unsure if you were breaking some unwritten rule of conduct or making yourself a social outcast. Celestia merely looked back out upon her kingdom in silence.
"No."
She spread her wings and jumped, soaring between your two balconies effortlessly and landing barely a foot away from you with a quiet hoofstep. She walked inside your room, and sat down at the foot of your bed, waiting for you to follow. You sat at the top of the bed, and waited.
"I rule so many ponies, and yet I'm so distant. Nopony has talked to me as an equal for over 1000 years. Even Luna, my dear sister, still hurts too much to truly open up, though I feel she's getting closer every day. I'm the center of attention for an entire kingdom, and yet I've never felt so alone. Thank you."
Her whole statement was shocking, but her last sentence most of all. You asked her what for.
"Asking if I was okay. Not being scared, or more concerned for social grace, or just unwilling to rock the boat. For keeping my student company, and for letting her entertain me with letters about you, amongst her other reports. For having enough respect for me to treat me as an equal, not a god. We're not so different, in a lot of ways. You're the only one of you, I'm just one of two". Celestia laughed and looked away, "I don't even know where Luna is right now. Off tending to the sky. She takes being alone much better than I, she always did. I'm sorry, you don't want to be burdened with the problems of an old mare when you're thinking about seeing home again."
Her voice, even while quiet and introspective, still held her motherly and light tone, though she dropped the commanding part of it. Even hearing about the woes of an immortal were made sweeter by it. All you could do was tell her that, and once you'd started, you couldn't stop - her voice made even the worst of news seem happier, and the head it came out of was beautiful. How her flowing hair was an awe-inspiring sight, and the long neck it flowed around was a sight for sore eyes. How her body was a symbol of perfection, truly fit for a goddess, and how her wings were so pretty. How, even though you were different species, she was still the most beautiful thing you'd ever seen, and how it broke your heart to see her alone.
The smile it brought to her face was more beautiful than all the sights Equestria had to offer, and her soft eyes stared into yours, the rest of the conversation going unsaid, but no less important. She wasn't just beautiful, she was alluring, irresistible, and bewitching. The species barrier meant nothing to you, it hadn't for quite some time. One doesn't go out drinking with Berry Punch without breaking a few boundaries, after all.
Her eyes reflected yours, emotionally as well as physically. The last millennia's drought of emotional intimacy may well have been mirrored physically, too. Her smile changed, growing sharper as it twisted into a wry grin. "It's been quite some time, my dear equal, I may be somewhat out of practice." You didn't care. At all. One touch from her hoof would feel better than the most talented touch from anyone else.
The two of you shuffled closer, moving along the bed until you were within arms reach. Cupping her long muzzle in your hand, you looked into her eyes one last time, to make sure she was sure. She was sure. Both of you started moving at the same time, your mouths meeting in a kiss. It took a moment to find a comfortable position for both of you, but soon enough it clicked, feeling just as natural as kissing anypony, or indeed anybody, else. Her tongue started to feel forward into your mouth, centuries of practice allowing Celestia to hide her insecurity behind a veil of pure confidence, diving forward as if she knew exactly what she wanted, and what she was doing.
Closing your eyes, you let her lead, feeling her tongue tasting around inside you, and tasting her own saliva in return, a heavenly broth - not strong tasting, but nice. The sort of flavour that, in tandem with the sensation of feeling her mouth against yours, and feeling her hoof resting against your leg, you could lose yourself in; So you did, letting out a quiet breath and running your tongue around hers, pulling back where she wanted to go, and pushing into where she didn't.
Much to your disappointment, Celestia eventually stopped, pulling back and staring into your eyes as the thin strand of mixed liquid bridged your mouths, before snapping. The conversation was unuttered and momentary, and soon you found yourself pinned between her and the bed, her body at the peak of physical fitness that was required to move that fast, diving forward and pushing your head into the pillows. She lowered her head to your ear, and began to whisper in a low, glorious tone.
"You are not my subject, and I can give no orders, but you know what I want just as well as I. Make me feel like a princess again"
It was not an invitation you could ignore, but her weight kept you pressed down, limiting your movement. No matter, you thought, as you bent your neck forward and pushed your head into her glorious mane, making your way to her exposed neck. Planing a series of light kisses just under her chin, you started to shuffle downwards as Celestia rose up just a little every time your lips landed, granting you a little more freedom each time. Your kisses made their way down her neck as your hands found their way to massaging and rubbing her forelegs, watching in glee as her head rested on the pillows behind you with her eyes closed shut, losing herself to sensations she had only distant memory of.
Eventually, you were far enough down to run a fingertip along the edge of her huge wings, the smooth softness making even the Pegasus-feather pillows seem coarse and crude by comparison. Her perfectly kept wings didn't require any maintenance, so you amused yourself by running a hand over each of them, following the feathers and tracing the bones, closing your eyes to better imagine how the air would run over them in flight, sending ripples through them from the streams and currents of a warm day.
Her wings reflexively bent down, surrounding you in an alabaster cocoon, shutting out the dim light of the distant moon and plunging you into darkness as you felt the heavenly feathers brush against your exposed skin. More pressingly, you felt your erect penis pushing against your loose clothing, and your hands couldn't bear to tear themselves away from stroking and pressing her powerful wings. It was pushing into Celestia's lower body, though, and even in her current state of revelling in feelings she thought she'd lost long ago, she could sense it.
Regretfully tearing her wings away from your loving grasp, Celestia pushed herself off the bed and let you wiggle out completely, leading kisses as you went, stopping as you reached between her hindlegs, allowing yourself to tease the being you'd pledge everything to just a little.
Standing up and off the bed, you looked back at her, watching her heavy breaths and the way her face pressed into the cushion as she lay there wordlessly, her aural, glowing tail raised out of the way as she presented herself to you. You thanked your past self for wearing such light clothing as you removed your coat and threw it to the ground, pulling off your light garments with similar ease before turning back and looking upon the beautiful form of your princess once again.
She had recovered, somewhat, bending her neck around to look at you with half-closed eyes and a wry smile. Her position was very revealing, her last tired motions leading her hindlegs to be trailing off of the bed, leaving her exposed ass at the very edge. The bed was just the right height; the white duvet beneath her marehood was quickly staining a darker colour as centuries of frustration let themselves out in one night.
Grinning back at her, you walked over and ran a finger along her cutie mark, ending your trail with a good slap to the side of her flank, producing a heavenly giggle. Never mind an equal, though thought, you'll show her the night of her life. Grasping her flank in both hands, you aligned yourself, pushing the head of your penis against her engorged lips, feeling the strong heat radiating off of them and the slick lubrication of a goddess. Holding tight, you slowly slipped in, pushing forward in response to her gasp as she raised head, the memories flooding back.
Continuing your thrust, you pushed all the way in, feeling her tight walls around you and her tail against your chest. It felt surprisingly solid. Eventually, you felt your crotch press against hers, feeling the raw heat of the sun goddess inside of you. She finally let out the groan she'd been holding in since you started, a beautiful, harmonious sound, but too quiet. You wanted more - you wanted her. Her tail proved quite solid as you took it in a hand, wrapping the glowing corona around your hand a few times to ensure it didn't slip out of your grasp; then you pulled.
Celestia squeaked, sounding more like Fluttershy than anything else for a moment, before pushing back at you. She was ready. You began slow thrusts, pulling yourself in with your grip on her tail as she pulled it in herself, aiding you. Your other hand rested firmly on her glorious ass, feeling her soft fur against your fingers. Your thrusts increased in both speed and power as both of you got more lost in each other's feeling, your natural lubrications mixing and squelching against each other as your mutual pushes grew more frenzied.
Celestia's otherworldly tones were kept busy vocalising her pleasure, a low moan escaping her lips at the peak of each thrust, slowly growing louder and louder as her body grew more and more excited - as did yours. Clinging onto her flank as your body started to quiver, you felt hers doing much the same, each thrust rippling through her body as her muscles spasmed and her neck arced back and her cries started to echo out into the night, probably terrifying any listening guards.
Your body could never compare to hers for endurance, and much as you tried with all your might to restrain yourself, being in the presence of such wondrous beauty made it impossible to not cum, sending torrents of hot, sticky, guilt-free semen deep inside her body. Celestia, using all of her thousands of years of practice, training, and mental stamina, managed to plunge her head down into the pillow in a futile attempt to muffle her deafeningly beautiful moan as the sensation drove her body over the edge in turn, causing her to contract and squeeze around you, the pleasure almost forcing you unconcious as you collapsed down onto her flank, kissing her back and hugging her close.
Several long moments later, you recovered enough to step back, pulling out and marvelling at the incredible mess you'd made of the bed. Walking around the side of it, you climbed on top and lay there next to Celestia, waiting for her to come back to you - 1000 years is a long time.
Many seconds afterwards, as you stared onto her beautiful body, she began to stir, raising her head. "Oh", she started, taking a moment to spit out the feathers she'd accidentally chewed straight out of the pillows, "Oh my, that was better than I remembered. I know why Twilight wanted to try this, now."
Her brow furrowed as she looked past you to the balcony. It was daytime. Well, you'd certainly never made a girl do THAT before. "Never mind, my people can manage with an extra hour of sun, though I expect a letter from", started Celestia with a happy smile on her face and a faraway look as you started to rub her body, before being interrupted by, as expected, a letter from Twilight flying in through the closed balcony doors.
"Twilight. From Twilight.", she laughed to herself. Both of you knew just how Twilight could be. You moved your massage up from her neck to her head, running your hands over her temples and scratching behind her ears. "Ooh, that feels nice. There's a place for you as a royal servant if you want it", she joked, "though we should probably hurry, the transportation spell is complex and will take time to prepare in order to get you home"
The twinge in your heart at the thought of leaving Equestria, Celestia, Ponyville, and so much else behind told you all you needed to know. You told her that yes, you wanted to go home, but that Equestria was your home now. Furthermore, you'd like to make it official, and become a citizen. You thought you already had the "respect and serve your princess" part down pretty well, so why not do it right? That, and you're not so adverse to taking orders.
Celestia smiled, and opened her mouth to speak, though her eyes already told you everything you needed to know, and wanted to hear.
"SISTER, WHERE IS MY NIGHT?!" echoed through the room as Luna, goddess of the night and the second most beautiful thing you'd ever seen landed on the balcony, throwing open the doors with reckless abandon as her mane flowed angrily around her. "GIVE IT- oh gosh, Cel, you didn't?"
"Oh, I did"
