Twilight Sparkle has been in love with Princess Celestia from the moment she first laid eyes on her. And who could blame her? The Sun Princess’s impossible proportions, from her impressive height, bodacious curves, wide hips, round ass, shapely thighs, and enormous breasts give her more raw sex appeal than anypony else in Equestria. As Twilight grew and matured, so too did her love for Celestia.

Now, with the Summer Sun Celebration almost upon them, Twilight receives an odd, yet urgent summons to Canterlot Castle. Little does the young alicorn know, the feelings are mutual.

Most Wonderful of Nights

Princess Twilight Sparkle had been fucking Rarity on the regular for upwards of seven months. No matter how busy her schedule, she always made sure to carve out a few hours in the week to enjoy a session with her generous, voluptuous friend. Making excuses for her frequent visits had been easy. After she ascended to Princesshood, Twilight saw her body undergo numerous transformations. Apart from growing wings, she had become tall, curvy, and busty, rendering her current wardrobe useless. As long as she returned to the castle with some manner of clothing in hand, she could avoid suspicion from Spike and Starlight.

The repeated sexual encounters fascinated Twilight. She supposed that, being the futa that she was, she had a beyond overactive sex drive that Rarity had awoken. Ever since their first time together, when Rarity had made Twilight suck her own horsecock, self-sucking until she came all over her face had become a morning pre-shower ritual. She also realized she had been going through what was essentially a second puberty, and being endowed with such a massive cock had rendered her almost perpetually horny.

Rarity had always been more than happy to slake her thirst for pussy. Twilight did not fancy herself a nympho like her friend. Rather, a horny teenage stallion felt more accurate. Whatever the case, being secret friends with benefits with Rarity had done wonders for her confidence. She was no longer ashamed of her body, and had even taken to dressing more provocatively, not afraid to show some of her vast lavender cleavage or her narrow, well-toned midriff. Although she did not mind wearing tight dresses or skirts that highlighted her defined ass and curves, she never wore anything shorter than a few inches above the knee.

If there was one thing she wanted kept secret, it was her cock. While she figured her friends would accept her for what she was, she felt it best if only Rarity was privy to that not-so-little tidbit about herself. Her cock was quite small when dormant, but even with habitual release, that was rarely the case. Instead, it was almost always semi-hard, with the head poking out of the sheath. In that state, it was around eight inches long, and a short skirt or dress posed far too great a risk for her liking.

Now that summer was almost upon them, she had to make Rarity get creative with her lighter clothing. As much as she wanted to wear shorts, there was no way for them to conceal a cock like hers. However, she need not have worried—Rarity came through, like she always did. Now, Twilight relaxed on a beach chair on the Castle of Friendship's topmost balcony. The chair was a brand new purchase from Quills and Sofas, bought during its pre-summer sale. Because she had grown well over a foot since her ascension, her old chair was now much too small, and she needed one for somepony of her stature.

Her long, shapely legs rested on white pegasus down cushions, which sat upon a polished steel frame. The temperature was rising over the weeks, but the cool breeze that brushed against her brought a contented smile to her muzzle. Her newest summer dress was perfect for such a day. It was an airy, lime-green garment with white trim that let her skin breathe. Despite their enormous size, Twilight's breasts were incredibly perky and required no support, jutting twelve inches from her chest. Rarity had taken full advantage of this when she designed the dress.

It hugged all of Twilight's ample and pronounced curves perfectly, from the hem of the skirt that brushed her knees to her hips and round ass to her slender waist and torso. When it came to the top, the dress opened up above her belly, with only a small amount of fabric covering the front of her breasts akin to a bikini. A thin string fastened behind her neck was all that held the dress in place. On most other mares, such a tiny string would not be enough to hold the chest in place, but Twilight's gravity-defying bust allowed for just that. The dress had no back to it apart from a few inches above the tail, and the sides had several stars cut out of them, shaped after Twilight's cutie mark.

She wished this respite from her busy day would last, but she guessed she only had maybe ten minutes left before she had to return to work. The Summer Sun Celebration was in a couple of days, and she planned on attending it in Canterlot, so that meant she had to overload her schedule during the week leading up to it. As a consequence, it had been ten days since she had been laid, and no amount of self-pleasure could make her feel less stir crazy. In fact, the last time she had hilted herself inside Rarity was when she had picked up the very dress she wore. That was also when she learned she still had some growing to do; after feeling particularly full of horsecock, Rarity had measured and squealed with delight when she found Twilight now reached seventeen inches fully hard, a whole inch more than when they had started fucking.

“You had best be careful, darling, or else I might not be able to take all of you if you keep that up,” Rarity had said.

Twilight squeezed her legs together as she felt herself harden at the thought of it. Not only did she love the feeling of Rarity wrapped tightly around her forearm-thick dick, but she also enjoyed the lessons Rarity always gave her. Not only had she gained a great deal of stamina, once managing to go for over forty minutes before finally cumming, but she had learned so many positions and techniques, she figured she could recite—and perform—the entire Kamare Sutra from memory. Yes, Twilight loved being fuck buddies with such a great friend who had an incredibly gorgeous body. She always found satisfaction when she entered Rarity after the white unicorn had recently been with a stallion. There was something about hearing that Rarity had missed her big cock that stoked the fires inside her.

But Rarity was not the alabaster sex goddess to whom Twilight's heart belonged. Even from a very young age, she had always had a thing for Princess Celestia. During that one Summer Sun Celebration so many years ago, she beheld the most radiant, beautiful thing she had ever seen. While it had been many years since then, Twilight could still see it perfectly when she closed her eyes…

She had stood the foot of a golden flight of stairs that led to a broad stage of white marble, atop which stood two quartets of muscular stallions, all clad in the gilded cuirass and sky-blue tunic of the Royal Guard. They were steel-grey unicorns, their white-and-grey manes formed into plumes by their galeas.

Each was behind a golden horn set with rubies on a black iron stand. Twilight's position at the front of the crowd, a courtesy offered to all little fillies and colts, allowed her to have a perfect view of the great crescent moon and sun blaze sculpture wrought of gold on the stage's centre. It was almost half-past five hours after midnight, and there was naught for illumination save for the cloudless starry backdrop of the night sky.

And then it happened.

An Amazonian mare, her skin the purest of whites, strode into view on the back of the trumpets' heraldry and a torrent of cheers. Twilight did not cheer along with the others; the resplendence she beheld had stolen her voice and left her mouth hanging open. The stories had always told of Princess Celestia's beauty, but they all fell woefully short. Her heliotrope, cobalt, turquoise, and cerulean mane and tail hair drifted about in the air of their own accord. She stood over eight feet tall, dwarfing the well-built Royal Guards at her sides. The way she moved had a regal grace and poise befitting the golden tiara set with an amethyst atop her head and the matching collar around her neck.

When she reached the front of the stage, a broad, loving smile covered her muzzle, and she beamed at the crowd, looking over the thousands who had gathered to welcome the first day of summer. For just a heartbeat, her magenta eyes landed on Twilight. She could still feel the light flutters in her chest from that moment. Then, Celestia had spread her arms wide and flared her wings to their full broad span. She looked skyward, and a pale golden glow enveloped her horn. A hush of anticipation fell over the crowd, Twilight staring in awe all the while.

Twilight did not know how long Celestia had hesitated before she floated up, up, and up with slow, deliberate beats of her wings, raising only half a foot at a time. As the Princess of the Sun rose, so too did the sun itself. Light crept forward, chasing away the dark, and when it fell upon Twilight, Celestia had reached the centre of the sun-and-moon sculpture. The sun shone directly behind her, bathing Canterlot in its radiance. Celestia had never looked so beautiful as she did then.

A cloth-of-gold gown clung to her impossible curves and expansive breasts that were so full that they all but completely covered her stomach. The back of the gown went all the way down to her hooves, but the front was cut just below the knee, revealing a pair of golden hoofguards attached to her lower legs with golden bands that criss-crossed all the way up her shins. All she wore on her arms was a matching pair of bracers. As the sunlight covered her, the myriad tiny golden scales sewn onto her gown caught the light and shone like a thousand, thousand small but bright suns all their own.

Then, Twilight was too young to know what sex was, but she innocently loved the Princess all the same. That innocence had faded nearly a decade later, when she lay in bed in the dead of night, buried beneath the covers, during the night when she had gotten herself off for the first time. She had that image of Celestia in her head all the while, that beaming smile etched into her mind as she convulsed from the throes of her first orgasm. Even recently, she often thought of Celestia, wearing that very gown when she pleasured herself. When she used her own massive tits to stroke her throbbing cock, she imagined that they were Celestia's, and that it was the Princess's mouth and not hers that sucked on her flared cock head along with the first several inches.

The more she thought about it, the more she had to fight the urge to jerk off right there. While her balcony afforded some privacy, she was always worried somepony might see her. A quick glance around told her there was no bucket handy, and the last thing she wanted was to be faced with the problem of cleaning up one of her enormous loads, or worse, spraying it off the balcony. According to her research, the amount of cum she discharged on a regular bases was enough to put a Royal Guard barracks to shame.

Without a bucket, wastebasket, bathroom, or Rarity on hand, her orgasms led to a terrible mess, so she always had to take great care to be careful when she got off. Twilight also seldom felt satisfied after just one cumshot. She knew only a few stallions could go for two rounds back to back before they needed a rest, but a mare's tendency to have multiple orgasms seemed to hold some influence over her cock. Once or twice, when she had felt exceptionally pent-up, Rarity had to milk her cock four times before it would soften. Those sessions had left Twilight sore for the next day or two.

“Hey, Twilight?” Spike's voice cut into her thoughts.

She sat up and swung herself around to face him, careful to keep her shapely legs clamped tight to prevent more blood from flowing into her horsecock. “Is it time to get back to work already? I thought I still had a couple of minutes.”

Spike shook his head and handed her a scroll. “No, but I just got this from Princess Celestia. I thought you'd want to see it right away.”

“You're right—I do.” Twilight magicked the scroll from his grasp and unrolled it in front of her face. “Thanks, Spike.” Her eyes scanned the Princess's familiar loopy cursive.

Dear Princess Twilight,

This probably finds you at a busy time, and for that, I apologize. However, I have an urgent matter to discuss regarding magic and lessons in friendship. I know you are planning to attend this year's Summer Sun Celebration in the capital, and there are some preparations that require your aid. I am confident when I say that this will be even more memorable than your first celebration.

Therefore, your presence is request in Canterlot by this evening. Please come alone, as these matters are best dealt with in discretion. You likely allocated many of your Princess duties for today, and I am sorry this disrupts your plans, but I would not make such a request if it were not of the utmost importance. I look forward to seeing you at this evening's supper.

Yours,
Princess Celestia

“Well?” Spike asked as Twilight rolled the letter back up, wearing a puzzled expression. “What'd she say?”

“She wants me to go to Canterlot.”

Spike ran a hand along the forest-green spines atop his head. “Huh? I thought you were already planning to.”

“Today.” Twilight took the scroll in her hands and reread it. “Something about special preparations for the Summer Sun Celebration, and—Spike!”

Magenta embarrassment crossed his face as Twilight pressed the unravelled letter against her voluminous chest in a vain attempt to cover it. She had caught him staring, yet again. “Uh, sorry, Twi,” he said.

Twilight sighed through flared nostrils. “It's all right, but please try to control yourself.” She could not bring herself to be too hard on him. After all, her body was not the only one undergoing changes as of late. Spike, despite being relatively young for a dragon, had crossed the threshold into adulthood. It had been more than twenty years since she hatched him, and his moulting had brought his body's development more in line with his age. Now he stood, trying to act casual with his right hand resting on the back of his neck. Due to the late-spring heat, he wore naught but a pair of navy shorts with scuffed white trim and a white string done in a double-knot bow-tie.

He was still a head shorter than their friends and had yet to fill out his wiry, lanky frame. It came as no surprise to Twilight that he was filled with similar urges to her, hence the staring. The irony of the regularity of how she fucked Rarity was not lost on her. Spike had good taste—she had to give him that. Rarity was a mare who tirelessly worked on her killer figure, with her hourglass curves, narrow waist, bubbly round ass, and her sizable G-cup breasts, whose roundness and firmness constantly threatened to (but never did) pop out whatever flaunting garment she wore. Twilight had come to realize she had all of those traits, except plenty more of them.

Spike, who had been staring at the floor in an awkward silence, offered up an apology. “So, are you gonna go? Right now, I mean.”

“Of course I'm going,” Twilight said. She stood, raised her arms, and unfurled her wings in a stretch, her shoulders and back giving several satisfying, subtle pops. “I'm just sorry I won't be around to finish the schedule.”

There was a drawn-out groan. “You mean I'm stuck here to do all that work by myself?”

Twilight felt bad for him, but a royal summons was a royal summons. “You won't be by yourself. You'll have Starlight.”

“Huh?”

“Princess Celestia told me to come alone.” She clapped a hand on his shoulder and gave it a squeeze. A warm, encouraging smile crossed her muzzle. “If there's something on there only I can handle, don't worry about it. Whatever it is she needs help with, it must be important. You know I wouldn't do something like this on purpose. But, although...”

Spike looked up at her. She was pleased to see him looking her in the eye. “But what?” he said.

“She mentioned something about a friendship lesson and magic, and she said it was urgent. What could she mean?”

“I guess there's only one way to find out, isn't there?” Spike said.

“I guess there is.”

Twilight had spent the train ride from Ponyville to Canterlot in solitude, pondering. She wanted to make sure she would arrive in the capital in time for dinner, so she had made a hasty job of finishing her already half-packed suitcase, saying a brief goodbye to Starlight, and making a brisk flight for the train. In doing so, she had foregone any opportunity to relieve herself in the bathroom, a decision she hoped she would not come to regret.

Being so pent-up, thinking of Celestia, and only having enough time to jerk herself off once in the morning had left her feeling quite nervous. Her dress, while tight around the ass, was loose in the front and went quite low, but it would do her no favours should she reach full-mast. It was futile to wish that Celestia's attire would help her in that regard. Princess Celestia was far from shy about showing skin or flaunting her gifts, but her wardrobe most often favoured the regal and the stately.

But with a figure that oozed sexiness, modesty was rather impossible. There was also no top in Equestria that was capable concealing such an impossibly huge rack. Celestia's tits looked positively gigantic in even the most slimming colours that covered them completely. As of late, Twilight was always of two minds when she met Celestia. A part of her wanted her to be strutting around in something skimpy, whereas the other wished she would exclusively wear baggy faux-fur coats, just so she could have an easier time reining in her hormones.

Now she stood before the tall purple-and-gold double doors that led into the palace's royal banquet hall. A pair of statuesque Royal Guards flanked the entryway, sharpened spears clutched in their right hands and held precisely upright. Neither paid her any mind as she gave the door two firm knocks.

Only a moment had passed before they swung open to reveal Princess Luna, who wore a curious smile in place of her usual austere look. “Good evening, Twilight Sparkle. We have been expecting you.”

“Thanks. And it's good to see you,” Twilight managed, doing her best to mask her surprise. Luna was seldom awake this early. Her attire was just as unexpected as her presence. Instead of one of her usual outfits, which often incorporated armour plates of polished obsidian, she wore a dress and matching elbow-length gloves of a deep satin that was so black, it seemed to drink the very light around it.

The dress went all the way up her chest, narrowing toward the neck where it was fastened. It left her upper arms and shoulders bare, as well as a crescent moon shape cut out of the chest, giving Twilight a perfect view of Luna's considerable cleavage. Luna, who was halfway between Twilight and Celestia in stature, took after her elder sister in every way, although with far less exaggerated proportions. Her round breasts, which were conveniently right at Twilight's head level, while certainly enormous, were noticeably smaller than Twilight's. This, coupled with Luna's stature of just over seven feet, made them look less large than they actually were.

The rest of the dress was far from plain. Diamond chips all over the top's front and sides were arranged into patterns of the constellations, all of which Twilight recognized. A three-inch wide sash of matte lavender studded with sapphires was cinched about her narrow waist, drawing attention to it. Farther down, the dress was cut away at the sides, starting from Luna's wide hips and putting her Cutie Mark and long legs on full display. The front and back went all the way down, to the point of caressing the floor. It struck a perfect balance between formal and sexy, and it served as a reminder as to why Princess Luna was the mare of stallions' dreams in more ways than one.

“Do you like it?” Luna asked. She turned around slowly, revealing a bare upper back. “The tailors only made the final stitches this afternoon. I am trying it on before my evening duties, to ensure it is satisfactory.” With her rotation complete, she shot Twilight an intense gaze from her cyan eyes. “I deem it most satisfactory. Don't you?”

Twilight, who felt underdressed, nodded. “It's beautiful. Perfect for the eve of the Summer Sun Celebration.” That odd smile had still not left Luna's lips, and it unnerved her.

The corners of Luna's mouth quirked, broadening her smile. “Most wonderful. Now come. My sister awaits your presence.” Without further formalities, Luna spun on her hooves and walked toward the royal dining table, her defined ass swaying from side to side as she moved.

After a brief hesitation, Twilight followed. Their hoofsteps echoed upon the castle's polished marble tile, the cavernous hall amplifying the sound. High above, a golden chandelier was agleam with candlelight, basking the banquet hall in its golden glow, along with the moonlight that poured through its numerous tall windows. The long, rectangular table, which was set with a pristine white silken cloth with a purple hem that rested an inch above the floor, revealed the next oddity of the situation.

Only two places were set. One, which was at the head of the table, had Celestia's high-backed golden armchair with red velvet cushions, and emblazoned with her Cutie Mark. The other chair, placed on the table head's right side, was one of the table's typical guest chairs, made from a steel frame and royal purple velvet cushions. Luna stopped at the guest chair and gestured at it with an open palm. “Your meal shall arrive shortly.”

As she took her seat, many questions came to the tip of Twilight's tongue, but the one she chose to utter was, “Aren't you joining us?”

“Nay,” Luna said, shaking her head. “I must retire to rest and prepare for tonight's duties. It is early yet, and I mustn't tire myself too soon.” With what Twilight could have sworn was a wink, Luna turned and made for the entrance.

Twilight only had a moment to admire her retreating back before a door on the room's opposite end swung open. She could not stop her mouth from falling agape. Walking toward her, massive boobs giving a slight jiggle with every step, was Princess Celestia, wearing the exact same golden gown she had when Twilight first beheld her all those years ago. Somehow, she looked even more beautiful, more radiant than she had back then. She beamed at Twilight as she approached, shining like the sunrises she brought.

Celestia had made it halfway to the table before Twilight recovered enough to close her mouth and sit up straight. She remained speechless, grateful that the tablecloth and the prominence of her own impressive bust concealed her hands which were pressed firmly against her crotch. It took every modicum of concentration she had to prevent her dark-purple horsecock from springing from its sheath like Jörmungandr during Ragnarok.

When she reached her chair, Princess Celestia halted and beamed at her. “Twilight! I'm so grateful that you could make it on such short notice.” She spread her arms wide.

Twilight gulped, smoothed the front of her dress, and stood. They each took a step forward, and Celestia swept her up in a warm, loving embrace. Twilight’s wings snapped open as she returned the hug, her fingers slipping for a moment on the frictionless gold scales until they caught on the minute gaps between them. For a moment, she was in heaven. She could smell the lavender fragrance Celestia wore. The height difference between them meant her face was squashed hard against Celestia's titanic bust. The Sun Princess pulled her in with remarkable strength, and Twilight was only too happy to oblige. She could feel the dual softness and firmness of Celestia's breasts through the gold-scaled fabric. It took all her self-control to not grab them and rub her head into them, like Rarity often liked to do to her. She kept her legs clamped like a vise, knowing full well that it would all be over if she popped wood against her former mentor's thigh.

All too soon, their hug ended. “Supper will arrive shortly,” Celestia said. “Please, sit. We have much to discuss.”

Silently, Twilight obeyed. As her ass touched the cushion, which felt like stone compared to Celestia's tits, she remembered to fold her wings, hoping her former mentor would think nothing of it. For a moment, she looked down at the placements before her. The dinner plate was a fine white porcelain, with a gold rim and Celestia's sun mark, also gold, in the centre. The smaller dessert plate complemented its larger brother, except its rim was silver, as was the crescent moon in the middle. She could see her reflection in the forks, knife, and spoon, which were gleaming steel. To round it out was a goblet with a silver handle and flicks of gold that licked the polished glass like flames, as well as teacups with a similar deign to the dessert plates.

Eating a formal dinner was a challenge for somepony with a bust like hers. She had to sit a foot away from the table just so her boobs would not end up covered in food, and she needed to make sure to always sit up straight. Thankfully, she had Rarity on hand to teach her how to eat exclusively using magic without looking like a savage, as she put it. Twilight had no idea how the even more stacked Fluttershy managed with no telekinetic assistance.

“Now,” Celestia said, “you must be wondering why I requested your presence.”

Twilight nodded. A pair of servitors, each a dignified-looking unicorn with slicked, combed hair and clad in a black tuxedo with a purple bow-tie, strode into the hall. One carried silver-domed plates and set them down. Twilight thanked them as they lifted the domes, revealing a medley of steamed broccoli, carrots, leeks, celery, sprouts, beets, and peppers, lightly seasoned with spices whose scents tickled her snout. Alongside them was an array of olives, tomatoes, avocados, wafer-thin cheese shavings and sauteed onions, mushroom slices, and potato wedges. The other held a shiny copper pitcher full of Neighagra Falls Vintage red wine.

“You said something about wanting help with the Summer Sun Celebration,” Twilight said, feeling hungry at the sight of all the food before her. “But I don't know what help I could possibly be.”

“Oh, you'd be surprised, I daresay.” Celestia chuckled and swept an palm over the first course. “We can discuss that matter in due time. For now, please, help yourself. I felt something more intimate would be more fitting for tonight, so I arranged for a family-style meal for two. You will forgive me for foregoing the soup, I trust?”

Twilight blinked and gave her head a clearing shake before her aura took a couple of bites' worth of each item and transferred it to her plate. “This looks delicious. You shouldn't have gone to the trouble.”

“Nonsense,” Celestia said, portioning out a helping of her own that was rather heavy on the cheeses. “This little food is a break for the castle's chefs compared to the functions that are the norm. And for how short notice and inconvenient this all must be, especially with what I will be asking of you, the least I can do is treat you to a good dinner first.”

Twilight took a bite—a piece of mushroom, sharp orange cheddar, red pepper, and onion—and chewed it. Nothing was overdone, and the cheese had been well-aged. The wine provided a sweet contrast to the spice, went down smoothly, and it was strong enough to bring a tingle to her fingertips. “I... still don't understand why I'm needed. Don't get me wrong, I love spending time with you, especially since I've had so little of it since opening the Friendship School, but I'm still confused. Are you concerned about how lessons are going? The curriculum? Or you wanted me to have my students blow the trumpets at the celebration instead of the Royal Guard? Or maybe—”

Celestia held up a hand to forestall further questions. “Oh, it's nothing like that. As far as I'm concerned, there could be no better Headmare of the School of Friendship than you. You have truly come into your own as a Princess, and for that, I could not be more proud.”

As much as Twilight tried to press her throughout the first course, Celestia always steered the conversation toward the mundane. Despite the supposed urgency of the summons, she was all too eager to speak of Baltimare cuisine, a squabble between a couple of nobles during last week's cricket match in the palace gardens, a manoeuvre she enjoyed at a recent Wonderbolts show, and the like. Twilight had given up entirely by the time they reached the salad, a rather basic arrangement of lettuce, spinach, celery, and a critic dressing with poppy seeds.

As the servitors brought out dessert, which consisted of piping hot tea that smelled of cinnamon, cloud cake, and vanilla ice cream, Celestia clapped her hands. “And now for the best part.”

After the first bite, Twilight could do nothing but agree. The cake was spongy, fluffy, and pure white. Its matching layers of icing were sweet and sugary, but not overpoweringly so. Generous amounts of melted white chocolate had been drizzled over it, and looked almost invisible. It was still hot, and went perfectly with the fresh ice cream that had only just begun to melt. Twilight washed each mouthful down with a sip of the tea, which left a slight spicy aftertaste.

As they took their time with their cloud cake, Twilight often stole glances at Celestia when her attention was elsewhere. She only saw her in that gown for perhaps a minute back when she was a filly, and that glimpse had evolved into her deepest fantasy ever since. Now, that fantasy sat before her, occasionally humming with content as she savoured her dessert. It was all Twilight could do not to stare.

When they were finally finished eating, and the plates, cups, and silverware had been taken by the servitors, Celestia cleared her throat, immediately drawing Twilight's utmost attention. “Now, Twilight, I feel it is time I tell you that the matters I touched on in the letter are connected.”

“They are?” Twilight said. She was not sure why she was surprised, considering how many times that had happened today.

“Yes.” On the turn of a bit, Celestia's shifted into a stern one. “Do you remember the friendship lesson during the last Summer Sun Celebration?”

Twilight would have laughed if Celestia did not look so serious. “You mean with the play?” A nod. “It was about how friends need to be completely honest with one another.”

“Indeed.” Celestia leaned forward. “But first, the matter of magic, now that we're on the same page. We both know that the spell that transformed you into an alicorn has had some... side effects.”

In a shot of panic, Twilight glanced down, but when her eyes found nothing but her huge lavender tits, she realized that was what Celestia was referring to. “Oh. Yeah. I'm not sure I'd have completed the spell if I had known, honestly.”

“Well, I think it suits you,” Celestia said, pleasantness once again returning to her features. “But, are those dimensions the exhaustive list of changes, your wings aside?”

The question sent Twilight's head spinning. A beat of sweat gathered on her forehead. “I—yes.”

Celestia folded her arms beneath her mammoth tits. “I thought you said we were being honest.”

“I don't—”

“Do you not think I didn't sense the wild magic's work when you ascended?” Celestia's words came swift and sharp. “Now I will give you another chance. Did your body change in any other way?”

Twilight felt trapped, despite her mastery of teleportation magic. A bead of sweat gathered on her forehead. Did Celestia know? How was it possible? Unable to formulate a convincing lie, all she did was give a meek nod. “I didn't want anypony else to know. It's not normal, and I don't want to change anypony's view of me—especially yours.”

“That's better.” At last, Celestia leaned back. “Such a condition is rather rare, but not unheard of, though it can certainly have an effect on a friendship. A positive one, perhaps?”

Several more droplets of sweat joined the first. Despite Twilight's relatively skimpy attire, she felt hot. “It—it wasn't on purpose.”

“But it is mutually enjoyable?” Celestia said coyly, raising an eyebrow. “I think that would have prompted you to be more open with those you can trust. Part of the power of friendship is being able to confide in others. You know this.”

“I do,” Twilight admitted. It was on the tip of her tongue, but she dared not utter it. “I can't tell somepony how I truly feel, especially now that I've got—this.” She pointed down. “It'd ruin our friendship.”

Celestia edged her seat closer to the table. “Are you certain of this?”

Twilight nodded. “I've lived with it a long time.”

“Yet it hurts all the same.”

“It does.”

“Well...” Celestia placed her hands on the table. “The feelings may be mutual, but you would never know.”

Twilight shook her head. “I doubt that.”

“Equestria is full of surprises. Heavens above, I should know, considering how many years I have walked upon it,” Celestia said.

Should she tell her? Could she? Somehow, it seemed as if Princess Celestia knew everything about her, even her most guarded secrets. Did she know of her true feelings—and had she all along? Twilight felt so rattled, she did not know where to begin, unable to tell if this was the opportunity she had yearned for all these years or all of her bottled up passion and lust reaching a boiling point. But who was she to look a gift horse in the mouth?

Twilight could not say how long she mentally wrestled with herself, but then, something came over her. She could not say whether it was the wine, the company, the golden gown, or just how much she ached from carrying her secret for so long, but she said, “I love you.”

Celestia wore a smile that showed a row of teeth as white as she was. “I love you, too, Twilight.”

“You don't understand,” Twilight said, the words tumbling from her mouth. “Not in that way. I love you, Princes Celestia. I always have, ever since I was a filly, before I even know what love meant, and as I got older, it just became stronger. I thought I'd meet somepony or grow out of it, but now, especially since I've gotten this... appendage, it's worse and worse. I can't stand it!” She covered her muzzle, heart slamming against her rib cage. “No... what have I done? I'm sorry. I'm so, so sorry!”

Celestia was at her side, resting a hand on her shoulder. “I know what you meant the first time. I have lived long enough to see through facades like yours. At first, I assumed it was fleeting, but it endured long enough to tell me that it was genuine.”

Still breathing hard, Twilight looked up at her.

“Since we are being truthful to each other,” Celestia said, “it is time I be truthful with you. I always admired your tenacity and determination. You are noble, brilliant, and selfless. You succeeded where myriad others had failed, and I watched you bloom before my eyes. As I did, that admiration grew into something far greater and more profound. At first, I did not understand what I was feeling. It was a curious, fluttering heat in my chest, and I found myself thinking about you during dull meetings, and soon when I lay down to sleep.”

Celestia heaved a sigh. “I had become taken with you. While I must confess that I find your new form pleasing, it was something more than mere infatuation. Unbidden, the feelings came, and only took root more quickly because of your immortality. I have always had to shield myself from love, for the pain of watching your special somepony slowly wither away into old age whilst your own body endures is unbearable. It is why my sister and I drew up the Royal Consort Decree over eleven-hundred years ago. But I, too, was afraid. How could it be proper? A consort is one matter, but this is a whole different manticore. Even after your ascension, I still could not justify it to myself.”

Twilight could not believe the words she was hearing. They sounded so unreal, like something straight out of one of her dreams, that she wondered if there had been some potent drugs added to the wine, and she was just asleep in her chair. “What changed?”

“Let us say that new information came to light,” Celestia said. “Why do you think I brought you here? Why am I wearing a gown I have not worn since that Summer Sun Celebration? My mind changed, Twilight. The ‘preparations’ I mentioned were only a front to give my letter enough urgency to convince you to come. Tomorrow and the following day will be busy, but now—tonight—before the festivities are upon us...”

For several moments, Twilight had forgotten how to breathe. She felt dizzy, and so giddy she had to cling to the table with her shaking hands. “Are you...? Even with my—?”

Celestia's muzzle met her own, and their lips locked. She was too stunned to move, and barely had the wherewithal to kiss back. Her nostrils drank in the sweet lavenders Celestia had pampered herself with as the elder alicorn leaned into their kiss. It was slow and measured, and used no tongue. But Twilight was content all the same, feeling lightheaded. Soon—too soon—Celestia withdrew. “Is that enough convincing for you?”

Not trusting herself to speak, Twilight nodded, still unsure if that had just happened. Celestia took her by the hand and said, “I think we should take this somewhere more appropriate. More intimate.”

Twilight stood and allowed herself to be led out of the banquet hall. They had not even reached the door when she knew exactly where Celestia was taking her. She made no attempt not to stare at the perfect ass swaying just in front of her, knowing there was no reason to be discreet about it any longer. “I still don't understand, though.”

A few paces from the door, Celestia turned. “Twilight, I have had many consorts over the centuries, mares and stallions, including those with your gift.”

“You have?”

“Well,” Celestia said, “it has been a few years since my last one. Contrary to popular belief, the Royal Consort Decree was never abolished. I have merely abstained from taking one, and Luna has not found one fitting of her tastes as of yet.”

“No, I mean, with a... with a futa.” The word sounded dirty when she said it.

Celestia laughed. “Oh, Twilight. Some of my most memorable consorts were Futanari. I have found that they are more often than not quite... potent.”

The sudden huskiness in Celestia's voice made Twilight gulp. “You have?”

“Indeed.” Celestia magicked the door open and led Twilight through it. Even from behind, Twilight could still see a copious amount of boob. “It is rather a consistent trait. Perhaps it is the combination of both sets of equipment that leads to such exponential results, but nopony has truly been able to say.”

“I wondered about that myself.” Twilight barely noticed the castle's corridors go past her as they walked.

Celestia's pace quickened. “So, you are also endowed, then?”

The embarrassed silence that folded served just as well as a confession. Twilight often wondered where Rarity put it all, but she dared not make such a remark, lest she say anything that might jeopardize what was about to happen. She had to resist the urge to take the spiral stairs that led to Celestia's bedchamber at a run.

There was a distinct lack of Royal Guards stationed in front of the chamber's double doors when they reached them. Gilded iron frames housed the thick crimson oaken panels in place. Celestia's mark was etched into a gold circle near the doors' arched apex, its lines set with rubies that gave it a blazing look in the torchlight. Celestia halted before the doors and turned to face Twilight. Something about her eyes betrayed her anticipation. “We are here at last,” she said.

“I've dreamed about this for so long.” Twilight wondered why she had not gotten hard yet. Perhaps how surreal the whole situation was had numbed her.

“I know,” Celestia said. Her horn shimmered pale-gold, and the doors swung open behind her. After giving Twilight an approving look, her eyes dwelling on the younger alicorn's perky purple breasts, she crossed the threshold. “I hope the accommodations are to your liking.”

Twilight followed Celestia inside, and for the first time, laid eyes upon the royal chamber. Fitting for Celestia's station, it was a spacious room and perfectly round. Columns of pristine marble separated the dozen windows that made up most of the walls and would have offered a spectacular view of not just Canterlot Castle, but the Equestrian countryside for leagues in all directions, were the curtains not drawn. The drapes were a rich violet, their hems cloth-of-gold fashioned into a rope pattern.

A gilded edging twelve feet above the floor separated the windows from the chamber's high domed ceiling, whose entire surface bore a breathtaking mural. One section of it depicted earth pony mares and stallions wearing linen tunics and stockings toiling away in a field beneath the beating sun. Another was of unicorns wearing silks in the stone chamber of a castle, in the midst of fashioning spells. A third showed pegasus legionnaires clad in polished steel armour not unlike that of the Royal Guard, flying above the clouds and directing them toward their fellow ponies. In the centre of it all, at the dome's peak, members belonging to all three tribes sat at a round maple wood table beneath a banner bearing Equestria's sigil of the Royal Sisters bracketing a sun and moon on a field of light-blue spangled with thirty-eight white stars.

“Admiring the work, I see. I had it commissioned during the Reneighssance period. Every time I wake, I look upon it as a reminder of what the foundations of this kingdom are and what binds it together.” Princess Celestia herself stood before a great four-poster bed near the chamber's opposite side. The silken drapes were white as ivory, held up by mahogany beams carved with spirals akin to those on a unicorn horn. Its top was fashioned into the shape of pegasus feathers. Celestia drew the curtains, revealing an expansive mattress that rested on the floor, but was four feet tall. Its sheets matched the curtains, as did the cases of the score of pillows arranged into two rows on the bed's opposite side.

“This is what heaven looks like,” Twilight said, regretting how cheesy it sounded almost before she said it. Then again, the bed did remind her of clouds.

All the same, Celestia smiled at her. “Let us hope it is what heaven feels like.”

The sheer elation was almost overwhelming. Princess Celestia, far and away the most beautiful mare ever to walk Equestria, was ready, willing, and standing by what promised to be the most large and comfortable bed in the kingdom. The twin braziers that flanked the door cast their light into the bedchamber that was closed off from the rest of the world as Celestia's telekinesis shut and locked the door behind Twilight. Celestia's golden gown caught the fires' lights and cast her in a divine glow. The white backdrop of the bed made it easy for Twilight to drink in her radiant beauty, and how the gown brought emphasis to her enormous bust, wide hips, supple thighs, and incredibly curvy frame.

Celestia stooped, unfastened the straps on her hoofguards, and stepped out of them. She shed her gloves, leaving her arms bare, and then removed her tiara. After setting the garments aside, she raised her right hand, turned the palm upward, and curled her index finger toward herself. Twilight's legs moved seemingly of their own accord, as if drawn by Celestia's gesture. Her hooves carried her across the floor, whose polished tiles were arranged in a crimson and white checkerboard, each separated by thin lines of gold. As she approached, Celestia sat in the centre of the bed, and Twilight joined her. She felt herself sink several inches into the soft mattress that provided just the right amount of support.

They were so close now, and Twilight stared into Celestia's loving, magenta eyes. “I can't believe this is real,” she said.

Celestia tucked a finger under Twilight's chin. “Frankly, it feels fantastical to me, too. From the moment you hatched Spike, I knew you were special, but when you completed Starswirl's spell and received the gifts it bestowed, you surpassed anything I had imagined. Little did I know, that was just the beginning.”

“I'm glad this didn't happen all at once,” Twilight said, pointing to her body. “My coronation would've been so embarrassing...”

“I'm sure the tailors would have had no trouble making something to fit those dimensions if Rarity did not already do so.” Celestia laughed and laid her left hand on one of her enormous breasts. “They are quite accustomed to such tasks.”

“It's not that... It's my... it's my cock.” Twilight looked away, but could not lower her head due to Celestia's finger beneath her jaw. “Like everything else, it didn't start very big—maybe a couple of inches when I first got it.”

“Curious,” Celestia said. “I do suppose that makes sense. The change to your body was noticeable immediately, though they were but a shadow of what happened since.”

Twilight gave a nervous chuckle. “Yeah. If I was the way I am now... everypony would've seen.”

“Oh?”

“With you next to me. I'll never forget that dress.” Twilight half-squirmed as she relived the memory. “You showed so much boob.”

“It was hot,” Celestia said defensively. “Judging by your attire, you should now have some empathy for my situation.”

“I do, and it wasn't as hot as you are. After all that had happened, how you were dressed, and those new, weird urges I felt... I was hard the entire time.” Twilight's face grew redder with every heartbeat as the confession escaped her lips. “I loved having everypony around, but I really needed some time alone.”

Celestia's hands were on Twilight's upper arms, just below the shoulders. “Oh, Twilight... If one thing about you hasn't changed, it is how adorable you are.” Her words did nothing to help with Twilight's embarrassment. “I am also grateful you think so highly of my appearance.”

“How could I not?” Twilight said. “Everything about you screams ‘sex goddess.’ Some stallions are nice, sure, but it's because of you that I've always been into mares with a body like yours. Look at girls like Rarity. They go through corset training to slim their waists, do lower-body workouts to make their asses look nice, and wear clothes to push out and flaunt their breasts. As hard as they try, nopony comes even close to you, and all of that comes naturally.”

“You aren't so bad yourself. Over the long years, I have been with mares, stallions, and even futas, of all shapes and sizes.” Celestia bit her lower lip for a moment. “I do so adore mares like you, Twilight. For a moment, I wondered if you had somehow gleaned my true intentions and desires from the beginning, what with how much of those massive breasts of yours were staring me in the face all throughout dinner.” When Twilight's only reply was slack-jawed silence, Celestia continued, “Of course, I know your opinion of me is not uncommon. My subjects have almost never been so forthwith about it as you have, but I know of many mares whose beauty should not be discounted—yourself and my sister among them.”

“Now you're just fishing for compliments,” Twilight said with a wry grin. “I don't really know what to say, though. You've been with so many ponies, I don't know if I can say anything you haven't heard several times.”

Celestia leaned forward. Twilight could feel her breath tickling her snout. “Actions speak louder than words.”

Placing her hands on Celestia's back, Twilight did the same. “They do.” For the second time that night, they kissed. Twilight gave a moan of longing as she pulled herself into the mare of her dreams, their gigantic tits pressing against each other. Celestia pulled her close and tilted her head from side to side, and they fell into a rhythm. As their kiss deepened, Twilight's tongue snaked out tepidly into Celestia's mouth.

Strong hands explored Twilight's back and curves, fondling them as Celestia's tongue met hers. Taking her cue, she did the same, running her hands along her former teacher's perfect body. Soon, their tongues cut a measured waltz between their joined mouths, with Celestia giving Twilight's tongue a little suck every so often. Rarity was a great kisser, but quickly became apparent that Celestia was in a class of her own.

A familiar tingling brushed Twilight's loins. Her horsecock began to twitch, but remained in its sheath. Twilight leaned harder into Celestia. The more they kissed, the more she wanted. But their kiss had not grown sloppy. No matter how much energy and raw passion Twilight wanted to pour into it, Celestia's measured, reserved pace directed their flow, with her with her putting out just a little more earnestness every so often.

Twilight could not say how long their kiss lasted. The only thing any of her senses could focus on was Celestia. Both mares draw in oxygen through flared nostrils. She loved the feeling of Celestia's impressive tits smothering her own. Without warning, Celestia's hands were on the back of her head, and she felt her tongue probing all the way into her mouth. The suddenness of it sent a jolt through her. After taking a flittering heartbeat to recover, Twilight turned her head and locked their muzzles as deeply as they could go.

Any reservations she had were gone as she thrashed her tongue about in Celestia's mouth, and she repaid her in kind. Without meaning to, she found her hands groping the sides of her fantasy's tits. Celestia did not seem to mind, as she only leaned farther forward, pressing Twilight into the bedding. Intoxicated by the passion pulsing in her veins and the lavender seeping into her snout, she began to squeeze Celestia's boobs.

Finally, it became too much. Twilight's head snapped back, breaking their kiss, and she let out a sharp gasp. Her tongue lolled slightly as she stared at the mural on the domed ceiling high above. Celestia did not waste any time. She planted affectionate kisses on Twilight's neck, making her descent toward her tits. Twilight reached for the back of her neck to undo her dress, but gasped again when she realized the strings were already untied.

Somehow, Celestia had made quick work of them without her having any idea. A surge of pleasure from her sensitive tits brought her attention back down. She shuddered and moaned as Celestia began servicing her expansive tits. Her hands trembled, as she had no idea what to do with them. Normally, when Rarity went down on her boobs, she took to groping herself, but Celestia needed no help. The sex goddess kissed her breasts and cleavage with fervour, her face buried in them while her hands groped, squeezed, and kneaded.

Twilight's pussy quivered, and her breathing grew short. Her violet nipples hardened, and Celestia rolled them between her forefingers and thumbs, shooting more stimulation through her. All Twilight could do was place her hands behind herself for support while her former teacher gave her a hands-on demonstration of how to worship a pair of big tits. Several minutes passed, and Celestia gradually rolled Twilight's nipples a little harder, making her legs twitch as pressure built up in her mare parts.

Celestia pinched her nipples. Hard.

Twilight cried out as an orgasm slammed into her nethers. Her arms gave out, and her legs convulsed as pleasure wracked her body. She bit her lip, moaning through her teeth as she squirmed, flat on her back, while Celestia prolonged her orgasm by sucking and nibbling on her tits. Her hands clenched bunches of sheets as she tried to hold on. Finally, when she thought it would never end, she felt her orgasm subside, her inner thighs damp from her juices. Unable to sit up, she looked at Celestia, who loomed over her and beamed. “How—how did you do that?” she asked, panting between words.

Celestia put the tip of her index finger between her teeth and giggled. “When you are as endowed as I am for millennia, you learn to work with them.”

“And when you've had dozens of ponies do things to them...”

“Do I detect jealousy?” Squaring her shoulders, Celestia pushed her tits forward, blocking her face from view.

Having recovered from her climax, Twilight sat up and ran her hands along Celestia's boobs that were still within the confines of her gown. “What you did to me, I've wanted to do to you for most of my life.”

Quick as a viper, Celestia leaned forward and kissed her full on the mouth. She teased her with a bit of tongue before withdrawing and flashing a foxy smile. “Then I think it is time for your waiting to end.”

Twilight held her breath as Celestia shimmied to the edge of the bed, threw her long legs over it, and stood. She turned and gave Twilight a glorious view of her plump, round, fuckable ass, and reached for the back of her neck. Fumbling for a moment, her fingers unlatched a minute clasp. Magic glowed and manipulated an inward-facing zipper. With painful slowness, it descended, peeling away the gilded parchment-thin silk that was tailored to be tight down to the millimetre.

First, she could see the nape of Celestia's neck, then her upper back between her wings. Down it went, curving inward as it went down the middle and the small of her back, before it curved back out again when it approached her hips. Gradually, it hit its bottom, just above the tail. Celestia undid two more clasps, each above her wings, and unhooked the zipper. Grinning, she turned back around. “Mmm... Are you ready?”

Twilight nodded.

“Very well.” Celestia delicately placed her hands on her shoulders and pulled down. The loops descended her arms, and the collar began to slide the expanse of her breasts. Endless, pearly white cleavage revealed itself when the shoulder loops reached her forearms. Then, she pulled her arms out of the loops, letting them hang at her sides. Only her massive, protruding bust held her gown in place.

Her foxy smile returned, and she tucked her fingers under the top hem. She pulled down, unveiling her goods inch by inch. Much like Twilight's, her tits ballooned out the farther they were from her chest, giving them a rich, bountiful fullness that demanded attention. When her gown at last reached the pinnacle of her mounds, she released her grip. It fell like a cascade of gold coins, pooling around her hooves.

There she stood, just as she had been when she was put on Equestria. Her breasts flowed from her chest perfectly, pressed together as if held in place by a bra. Easily beyond thrice the size of her head, covering her flat stomach all the way until just above her belly button. Each breast was capped with a plump rose-pink nipple that stood erect.

Celestia took a deliberate step with her left leg, lifting it above her garment. With her right leg, she kicked back, sending the gown flying into a curtain behind her. Her thighs were even thicker and more shapely than Twilight had imagined, yet still left a sizable heart-shaped gap below her pussy, which was a thin pink slit. It looked tight, and the clear droplets of love-dew glistening in the braziers' light betrayed its lust.

“I... you...” But words utterly failed Twilight. Often, during moments alone, she had thought of a whole range of things to say to Celestia if the impossible happened and she found herself in exactly this position. But, from elaborate Old Ponish poetry to a simple “I want to fuck you,” nothing seemed adequate or fitting.

With her wings flared, Celestia prowled toward her, her tits rippling with each step. Celestia stopped at the foot of the bed and licked her lips. “Now, I daresay it's high time you show me what you have hiding under there.” She indicated Twilight's dress, whose top was bunched around her hips. “It has been far, far too long since I have been properly rutted.”

The sudden vulgarity took Twilight aback. Celestia had always spoken with such a motherly and delicate tone, she often wondered if she was even capable of dirty talk. “You're a...” She took a moment to find the expression Rarity had explained to her. “A size queen?”

“Magic wands are one thing,” Celestia said, “but no spell can make them adequate fill-ins for the real thing. And there is nothing quite like being thoroughly filled, especially since even an exceptionally gifted stallion cannot even come close to hitting the deepest nerve endings of a mare of my stature.”

Understanding dawned on her. “So, does that have something to do with why you're into futas?”

Celestia nodded. “I have found that most stallions cannot measure up to even the more modestly blessed mare. Truthfully, I did not much fancy them during the first century of my rule. It was not until one night, when Luna was practically mimicking a banshee, were my eyes opened. I knew it would have taken somepony quite huge to make my sister scream like that, so I lay in wait outside her chambers.

“Soon enough, the doors opened, and out came a mare with dishevelled hair and a triumphant smile. Puzzled, I waited for the stallion, but he never came. Curiosity eventually overcame me, and I entered to find Luna alone. When I questioned her, she explained.” Looking skyward, Celestia gave a wistful sigh. “After much pleading, I convinced her to share. Initially, I had difficulty taking all of her in. But enough of that. You have made me wait long enough. I wish to see you—all of you.”

“You didn't seem to have any trouble stalling after you helped yourself to my tits.” Despite her argument, Twilight made her way to the edge of the bed.

“But I am a Princess.”

Twilight laughed. “So am I.”

“Point taken.”

Too overcome with lust to draw it out any further, Twilight stood and kicked off her dress, tossing it into the tiled floor next to Celestia's. It was Celestia's turn to gasp. Although it was still soft, Twilight's horsecock hung at six inches in its protective sheath. Before Celestia could make a move for it, Twilight darted forward and wrapped her arms around her, pulling Celestia into a deep kiss. She could feel the warmth of the royal snatch against her cock as they pressed their bodies together.

There was urgency in the way Celestia's tongue moved. This time, instead of feeling the elder Princess's hands on her back, she found them fondling her ass. She sucked on Celestia's tongue and groped her massive tits. They felt even better without anything covering them—so firm and plush. Even though their boobs were smooshed together, Celestia still left plenty of overflow for her to grab. Unable to resist any longer, she broke their kiss and dove in.

Twilight did not know what she wanted to do first. Her face was full of white pony boob, and she wildly kissed and groped everything she could find, constantly shifting her attention. After a few frantic moments, her lust drove her to heft one of Celestia's massive breasts and take the nipple into her drooling mouth. She sucked for all she was worth, licking and nibbling on the erect bean while both hands groped and squeezed up and down the rest of the boob's expanse. There was just so much to give attention to, she wondered if she could have satisfied just one breast with two extra pairs of hands.

Before switching to Celestia's other tit, she bit down on the nipple in her mouth, eliciting a sharp, “Aaah!” from her. She pressed her head into the cushy boob, and she felt one of Celestia's hands on the back of her head, helping her. Twilight whimpered with happiness as she immersed herself in alabaster tits. Then, she started kissing between Celestia's breasts, doing deeper and deeper into her seemingly never ending cleavage.

She felt the boobs in her face parting before her as she pressed forward. At long last, she found the patch of chest between Celestia's breasts and planted a kiss on it. Twilight gasped as she felt tits smothering her head completely, from above, behind, and below it, as well as the sides. Celestia's boobs were so big, they could fully engulf her entire head when squeezed together. All Twilight could do was grope and kiss them for dear life.

Of all ways to die, being suffocated like this was certainly the breast. But as she found herself short of breath, Celestia released her and stepped back. She fondled her own tits, a sign that her composure was beginning to slip. “Did you like that, Twilight?”

Panting, Twilight nodded. “We need to do that more often.”

“That can be arranged.” Celestia winked. “But now, it is my turn.”

“Wha?” Twilight said as Celestia came close and thrust her palms into the younger alicorn's shoulders, pushing her back onto the bed.

Celestia knelt and took Twilight's cock in her hands. She ran her tongue up and down its growing length, twisting her hands along it to spread her saliva. The sight of the Princess of Equestria herself, on her knees, naked, and servicing Twilight's cock, struck her as bizarre. But how strange it was did nothing to stop the gradual flow of blood into her cock. She ran her fingers through Celestia's enchanted hair as her flare poked from the sheath. Precum had already began to gather on its tip.

With Twilight's hands guiding her, Celestia took the entire thing into her mouth and started to suck, her muzzle firmly against Twilight's crotch. Twilight moaned and crossed her legs behind Celestia's head. Now at eight inches, she was not yet hard, but that was changing in a hurry. She felt herself lengthen and thicken in her lover's mouth. Twilight's massive tits heaved as she took deep breaths. The things Celestia was doing with her tongue felt so good, she did not want it to stop.

Celestia stared into her eyes the whole time she sucked, her gaze hungry and eager. With one hand, she ran her fingers along Twilight's pussy lips, while she groped her own tits with the other. After several minutes of audible slurping, she slowly withdrew, Twilight's horsecock considerably thicker than it had been when she first took it in her mouth. Now hard enough to stand on its own, it protruded a good ten inches from Twilight's body. “My, you are big,” Celestia said, giving the head a kiss.

“It’s gonna get bigger,” Twilight said. “I hope you can handle it.”

Celestia traced a finger along Twilight’s pussy lips, sending tingles through her nethers. With the tip of her forefinger slick with juices, she gradually inserted it, bit by bit, until it was all the way down to the knuckle. Twilight gasped and felt her marehood tighten around the finger, which began to move. Grinning, Celestia twisted and curled her finger, sliding it in and out.

Twilight’s legs and cock twitched from the stimulation. That was when Celestia inserted a second finger. She plunged them in and out, slowly at first, but gradually picking up speed. Twilight moaned and looked skyward, feeling her dick harden further. Her pussy responded to the ever-mounting pleasure by clenching and unclenching around the digits fucking it. A new surge of ecstasy hit her as Celestia thumbed her clit.

Precum dripped down her hardening shaft as Celestia kept diddling her. Celestia’s tongue caught it by the time it was halfway down, and she dragged it up, inch by inch, lapping up the trickle of pre from Twilight’s drooling cock. When she reached the head, she puckered her lips and slurped away, fingerbanging her young lover all the while.

Just as Twilight felt on the verge of a female orgasm, she felt Celestia withdraw her fingers. After making a display of licking her fingers clean, she placed her gigantic tits on her former student's thick thighs, squishing them against her mare meat. “I think I'll manage.” With her hands firmly grasping her tits near the base, she rubbed them up and down along Twilight's length.

Twilight had received plenty of titjobs from both herself and Rarity, but none like this. Rarity's rack, while quite large and perky by almost anypony's standards, could not hope to engulf all she had to offer when it started to engorge, and physical limitations prevented Twilight's own prodigious bust from covering the whole thing. She groped and squeezed on Celestia's boobs, and her hips started to give little jerks as her horsecock continued to grow.

Several minutes passed before the head poked from between the white tits covering it. Celestia opened her mouth and let herself drool on it a little before diving down into her own pillowy boobs and taking the head into it. She caressed it with her tongue, bobbing her head up and down and noisily slurping away. Twilight shuddered from the combined sensations of Celestia's adroit mouth working away at the head, her tits squeezed tightly around her shaft, and the feeling of her hands overflowing with Princess boob.

Moans mingled with her sharp breaths as pleasure throbbed along her ever-increasing length. Every so often, Celestia would swallow globs of the precum that continuously trickled into her maw. The amount of practice she had done over the past seven months as well as the sheer size of her horsecock meant she took quite a while to become fully hard, but she now felt the flesh growing taut.

Celestia must have noticed, too, for she started to bob deeper, taking as many as six inches at a time before sliding her lips back up the spittle and precum-slick shaft all the way to the flaring tip. When Celestia went down, her face went deeply into her tits. “Yes, yes—keep going,” Twilight said, her voice strained. Already boasting the girth of a wrist, her cock expanded and grew another two inches as Celestia's cheeks clamped down on it and her tongue circled the crown.

A heartbeat later, Twilight grunted and pushed her hips forward. Precum spilled from the tip, rushing straight down Celestia's throat. There was a wet pop! as the elder Princess recoiled, coughing from the sudden burst of liquid. Some of it must have travelled down her windpipe, Twilight realized. “Somepony is excited,” Celestia said as she licked her lips.

“You give amazing head,” Twilight said. The amount of pre that had just issued from her cock was probably twice what most stallions could shoot on a good day. “It's way better than what I can do, and I do it every morning.”

“You self-suck? That... that sounds so fucking hot,” Celestia said. A pink tinge appeared on her cheeks, and she giggled.

“Princess Celestia!” Twilight's tone was half-scolding.

“That was a bit unbecoming of me, wasn't it?” Celestia said with a wolfish grin. She slowly withdraw, her boobs brushing against the lubricated cock shaft. “Did you know there was a time in Equestria when bad fillies who said bad things were beaten with rods? I quickly abolished that practice, of course, but... I think I've been a bad filly, and it would appear we have just the rod handy with which to punish me.”

Heat rose in Twilight's face, and more precum had already begun to gather on the tip of her horsecock. For a mare who acted so dignified, Princess Celestia was kinky. “That can be arranged,” she finally managed.

“Good.” Now that Twilight's cock was freed from Celestia's breasts, the Sun Princess ran her hands up and down the fourteen-inch length with admiration. “Heavens above, I should have known. Such impressive size runs in your family; you are even bigger than your brother!”

“My? How would?”

Celestia squeezed Twilight's shaft with her right hand. Her thumb and middle finger could only barely meet around it. Giving it a few quick jerks, she said, “Come now, Twilight, do you think I need the Royal Guard for protection? You and your friends fill that role better than they ever could. It was indeed a sad day when Cadance took Shining Armour away from Canterlot, but I am pleased that he is happy.”

“I can't believe you used to fuck my brother...”

“If it makes you feel better, he was my last. It was shortly after the wedding that I began to develop strong feelings for you, and I could not bring myself to take another into my chambers,” Celestia said. A trickle of precum ran down Twilight's perfectly smooth shaft, and she intercepted it with her tongue. She dragged it up the shaft, cleaning it and all the pre that had gathered on the crown. “I was saving myself for you. For this.” She gave the cock a squeeze.

Twilight could not bring herself to be angry. After all, she had fucked Rarity more times than she could count. One of her hands idly groped one of her own tits. “Before we go any further, I should warn you. I cum lots. When you were sucking me off, I didn't finish with my cock. That was only precum.”

There was no surprise on Celestia's face. If anything, she looked amused. “I know, and I would expect nothing less of such a monster.” In a surprising display of strength, she grabbed Twilight by the waist and tossed her onto the middle of the bed. Her wings flared, and in a fit of passion, she dove on top of her, kissing her passionately while groping her lavender tits. “I want it. I need it, Twilight,” she said between kisses.

Twilight's cock towered in the air as Celestia's twitching pussy ground against the base of its shaft. She fondled every part of the larger alicorn she could find as their combined weight made her sink a few inches into the mattress. The next few minutes went by as if she were in a daze. They groped each other with continuing urgency, and their kiss became sloppier and sloppier. She was so intoxicated from lust that she failed to notice Celestia repositioning herself.

She definitely took notice when her bulging eyes saw Celestia's dripping pussy suspended no more than an inch above her muzzle. Needing no further prompt, she took two handfuls of Celestia's bubbly ass and pulled herself in, eliciting an excited moan from her lover. She kissed, licked, and lapped at the mouthful of pussy, all the while groping Celestia's rump with busy hands.

Meanwhile, Celestia displayed far more control. Her larger size allowed her to stroke Twilight's horsecock with her tits while her mouth went to work on the younger alicorn's pussy. Despite the lashings her own marehood received, she started out by teasing the lips with her tongue, then sucking on and kissing them. The torturous teasing only spurred Twilight on to squeeze Celestia's ass harder and lick her insides with more urgency.

Soon, Celestia's muzzle was in her snatch. It was much longer than Rarity's, allowing her to reach several inches farther in, her tongue brushing against some of Twilight's deeper nerve endings. Breakers of pleasure wracked her body as the tits on her cock, the muzzle in her nethers, and the delicious pussy on her face formed a cocktail of ecstasy she was only too eager to drink.

The feeling of a skilled mouth inside her pussy vanished.

But Twilight was not left wondering why for long. A great shudder ran through the pony on top of her. Pussy lips clamped down on her muzzle, and Celestia said, “Oh, T-Twilight... I'm—!” She moaned, long and loud as her orgasm hit her. Twilight lapped up the sudden rush of marecum as Celestia continued to shake. When her orgasm had begun to run its course, she planted a kiss on Twilight's cock head. “You're good. Normally, it takes a lot more to make me do that.”

The pink pony pussy covering her face prevented her from replying. Instead, she continued licking. Moments later, Celestia picked up where she had left off. Twilight had already been close, and having her sex fantasy cum on her muzzle had driven her wild. A familiar loss of control spread from her nethers to up her torso. As the last of her resistance faded, she spanked Celestia with both hands, the thwack! echoing through the bedchamber, and came with her pussy.

Her cock gave several jerks as she wriggled beneath her lover, overcome by her climax. She could feel it growing turgid, and a hot pool of precum gathering atop it. Moaning, she rode out her climax. As much as she enjoyed cumming with her cock, a good orgasm with her mare parts made her whole lower body feel so good. When it petered out, she noticed Celestia had stopped servicing her.

“You mean you weren't fully hard yet?” Celestia's voice was equal parts astonishment and excitement. “It's so huge! I never thought...”

Tilting her head back, Twilight freed her muzzle from her lover's nethers. Although she could not see it presently, she knew exactly what Celestia marvelled at. A network of pencil-thick veins pulsed along the length of her cock, its flared head more than enough to fill her palm. The pillar of flesh had the girth of the thickest part of her forearm. “It's seventeen inches,” Twilight said.

“And it's still growing?” Celestia said hopefully.

Twilight gave her ass another slap. “I'm pretty sure it is. It's an inch bigger than it was at Hearth's Warming.”

Celestia swung off her and craned her neck, clearing her throat. "My goodness, Twilight, what do you feed that thing?"

"Rarity, mostly," Twilight blurted.

They paused, staring at each other for several moments, and then burst out in laughter.

“Please, do me a favour," Celestia said. "When you cum, try not to hit the mural. Having that cleaned would raise questions I would rather not answer.”

With how much her cock throbbed, Twilight found it more and more difficult to think. “Shouldn't we get a bucket, or something? I won't aim up, but it has to go somewhere.”

“Will these suffice?” Celestia asked, hefting her tits.

Twilight gave a mechanical nod as Celestia opened her mouth and took the entire head in without difficulty. She sucked and slurped, corkscrewing her hands along the shaft as she lowered herself farther down the shaft. “Ooohhh,” Twilight said. Inch after inch of her futa cock disappeared inside Celestia's mouth.

She could see the impression of her shaft in Celestia's throat as she kept going with no signs of slowing down. Over half of Twilight's cock was down her lover's gullet. It was so incredibly tight. Even when Celestia reached the medial ring over ten inches down, she kept going. Twilight's jaw hung open as she watched the erotic display. Celestia's grasped her ass, squeezing it as her lips slid down the steel-hard summer sausage between them.

Throaty gurgles filled the room as Celestia reached the base, her muzzle pressed firmly into Twilight's crotch. She never thought anypony could take all of her like this. When she had gotten over her surprise, she grabbed Celestia's horn with both hands, “Oh fuck, oh fuck, oh fuck,” she said, pulling her cock several inches back. Then, she slammed it back in, all the way to the hilt.

A resounding smack on her ass told her to continue, and she was all too happy to oblige. She began savagely fucking Celestia's mouth with powerful thrusts. Clenching her teeth, she pistoned her hips back and forth. Every time she drove herself forward, she could feel Celestia's hands digging into her ass, aiding her momentum. She slammed into Celestia's muzzle over and over again. Her throat felt so good around her cock.

But no matter how incredible it felt, she fought any urge to cum. If Celestia was giving her the best fuck of her life, then the least she could do was repay her in kind—a difficult task when she considered her lover's experience. If nothing else, she was determined to outdo Shining Armour. In spite of it all, her endurance began to wane. All she could do was plea to herself to not cum.

But her cock swelled, preparing for release. She pulled back six inches, clenched her teeth, and hilted, holding Celestia's head in place for several seconds. Her body shuddered, and somehow, nothing save for a few generous dollops of precum escaped from the tip of her maredick. Sighing with relief, she released Celestia, who dislodged the cock from her throat and sucked in great gulps of air.

“I must say,” Celestia said, panting and wiping a strand of drool from her muzzle, “you really know how to give it to a girl. I had almost forgotten what it felt like to deepthroat such a beast.”

Twilight's left hand clenched one of her boobs, the flesh spilling between her fingers, while the other gently stroked her cock. “Your mouth and throat are even better than I imagined.”

“You somehow look even harder than before.”

It was true. Being on the brink of release had made Twilight's member swell to the point of aching. She often wondered about it. Even when fully erect, cocks often grew slightly when they were about to shoot their load, but Twilight found that with her hyper-sexuality, her own would often stay that way until she was completely satisfied once it reached that point. Before her, Celestia was on her knees, her enormous chest heaving as she refilled her lungs.

Almost blind with the haze of lust, Twilight dove forward with unrestrained passion. The tackle sent Celestia crashing onto her back. Wasting no time, Twilight pinned her and kissed her fiercely. With their boobs squished firmly together, she clamped down on Celestia's wrists, holding her arms in place. Her cock throbbed with want against their bellies, more than half of it sandwiched between both sets of mountainous tits.

She felt Celestia's legs intertwine with hers, and her hips started to move back and forth of their own accord. A steady trickle of precum lubricated their tits as their tongues lashed about in each others mouths. Twilight could smell their love juices mingling with the lavender Celestia wore as her snout sucked in air. Half-lidded, she pulled back, their muzzles a hair's breadth from one another. “I need it so bad.”

“I need it, too.” Celestia's voice bore the same hunger as hers. “Please, give it to me, Twilight.”

“Can you...”

“Can I what?”

A pink tinge bloomed on Twilight's cheeks and spread across the ridge of her muzzle. “Can you call me your faithful student, like you used to?”

Celestia leaned up and kissed her. “Take me, my most faithful student.”

With a moan, Twilight released Celestia's wrists and pulled back. Her cock slid out from between her former mentor's tits and down her stomach. When it reached Celestia's thighs, Twilight grasped it near the head with her right hand and just below the medial ring with her left, levelling it with Celestia's pussy. Celestia spread her lower lips open with her index and middle fingers.

Then, slowly, Twilight pushed forward.

Two moans filled the royal bedchamber as Twilight Sparkle entered Princess Celestia for the first time. She had no trouble easing the head in, meeting only just enough resistance to make all her cock's nerve endings nova with pleasure. She grasped Celestia's slender waist right where it blossomed out into her wide hips and continued to penetrate. Celestia's eyes were closed and her mouth was open as Twilight filled her inch by inch.

Her throat had felt good, but this was something else entirely. Celestia was so warm, moist, and inviting around her cock. And tight. So incredibly tight. But despite her abnormal size, she had no difficulty cramming herself farther and farther inside the mare of her dreams. Her grip on Celestia's hips tightened as her lover's marehood consumed more of her dark-purple length.

Celestia's pussy lips soon kissed the medial ring. “More, more,” she said. “Please, my student, fill me.” She had taken to rubbing her clit with one hand while clenching a fistful of bedding with the other. Her legs wrapped around Twilight's back. “Aah! It's been so long since I've felt something this big inside me.”

Twilight's tits squished against Celestia's as she leaned forward and bored herself even deeper. At last, she hilted. She grew still, savouring the moment and etching the myriad sensations coursing through her body into the deepest recesses of her memory. But husky, breathless command of, “Fuck me, fuck me!” from Celestia spurred her into action.

Flaring her wings and adjusting her grip, she straightened her back and began to thrust. With Celestia's legs still crossed behind her back, she could withdraw no more than perhaps half a foot before she hilted herself again. She adopted a steady rhythm, using her curvy hips and tensed arms to give her movements more power, each one ending with a slap of their crotches. The way Celestia's massive tits rippled and bounced from every impact was so hot. It drove her wild, encouraging her to go harder.

Her own boobs flopped about as she hammered away. A continuous torrent of pleasure engulfed her senses. Occasionally, Celestia would squirm on her cock. The minutes melted into one another as she kept moving. Last year, this would have tired her out, but the regular practice she had dramatically increased her endurance, which her overwhelming passion only further enhanced.

Celestia took one of her alabaster tits in her mouth and began sucking on it while groping at Twilight's swinging breasts with both hands. Twilight beat her wings and clenched her teeth every time she drove herself back in, holding on for all she was worth. Around her, Celestia began to tighten. She did not allow it to slow her pace, and after another five thrusts, the elder Princess came.

Squeezing Twilight's tits, Celestia howled with pleasure and writhed around the hard, overly engorged purple rod buried a foot and a half in her nethers. Twilight leaned back, looking skyward and moaning as Celestia kneaded her tits. It was all she could do to not blow her load right there. As Celestia's orgasm burned itself out, she leaned forward and allowed herself to rest on the larger alicorn.

She did not know how many times she could edge like this, being so pent-up already. More and more pressure built inside her, but she managed to keep herself corked up for the time being. The size difference between the two meant her new position had the fortunate side effect of her head being buried in Celestia's tits. Celestia, who had not recovered from her mind-shattering climax, gave sighs of ecstasy as Twilight grabbed her boobs, kissing and sucking on them, while sliding her cock back and forth.

Still a bit winded, Twilight started out gentle. But what her thrusts lacked in strength, she made up for in length, pulling as many as ten inches out before going back in. After several minutes, she felt Celestia's hands on her ass and curves, often pulling her back in when she reached the pinnacle of a thrust. She gasped when she felt a pair of lips around her horn. To her surprise, she found it oddly arousing, even though it had hardly any nerve endings. Celestia was so cock-crazed, she had taken to sucking on the most phallic thing she could find.

Twilight began to go harder, faster, and deeper, until the bed shook from the pile-driving she gave Celestia. She tightened her grip on the enormous tits spilling out of her hands and nibbled on the nipple in her mouth, earning herself a hard spanking. The sex-addled Twilight kept up her fevered pace for another handful of minutes before Celestia came again, spanking her with both hands and trying to hold her in place.

But Twilight kept going, thrusting as long and hard as her hips would allow. She felt herself being lifted into the air as Celestia arched her back, lost in the throes of her orgasm. Determined to prolong it, she kept giving it to her with her huge, throbbing cock. It was only when she felt Celestia begin to relax that she allowed herself to stop. When she did, Celestia pulled her into a long, sloppy kiss.

“You have learned well, my student,” Celestia said, kissing her between words. “Such coital acumen, on a mare so young... and hot.”

Needing a rest from the sheer amount of fucking she had just done, Twilight withdrew her horsecock and helped Celestia sit up. There they huddled, with their boobs pressed together and Twilight's cock between them, tenderly kissing. “This is all I've wanted my entire life,” Twilight said as they made out. “I need to make you feel as good as you make me feel.”

“You've done more than that already, my faithful student,” Celestia said. She glanced down. Twilight's flared cock head poked between their tits. “But this fellow needs more love. I'm going to make you cum.”

“I can already feel it,” Twilight said as Celestia went down on her. “Ooh—it's gonna be a huge load.”

Both mares used their incredible tits to stroke Twilight's dick while Celestia slurped and sucked. But soon, Twilight leaned forward and nudged her off. She took herself in her mouth, lapping up the dollops of her own precum. She loved sucking herself off, and hoped Celestia enjoyed the show. The head alone was almost enough to fill her mouth, her cheeks contracting around it.

Soon, she felt Celestia's muzzle on hers, and she let her continue the blowjob. They took it in turns to suck Twilight's horsecock, all the while servicing the shaft with their breasts. Pleasure rippled down the length of her cock from all the oral attention it received. Eventually, she pressed her muzzle into Celestia's and began to kiss her. Their upper lips were locked, while their lower lips were pressed against the crown of her cock. Dancing, their tongues twisted with each other while constantly licking the fleshy plateau of Twilight's cock head.

Another shudder rippled through Twilight, causing Celestia to pull back. She placed her hands on Twilight's shoulders. “Do you think you can last a bit longer?” A nod. “Good.” Standing, she straddled her, her pussy lips brushing against Twilight's cock head. Celestia's eyes rolled into the back of her head as she impaled herself, gripping Twilight's shoulders for support.

Twilight placed her hands on Celestia's hips, guiding her down. By the time Celestia was on her knees, the young alicorn leaned up and kissed her. She felt so hard, ready to burst, but she held herself at bay as she bottomed out. They continued to kiss, and Celestia began to ride. This is truly what Twilight had longed for. Equestria's pearly skinned goddess with the biggest, most perfect pair of tits she had ever seen, was on top of her, bouncing on her horsecock and moaning into her muzzle as they shared a passionate kiss.

Each time Celestia came down, Twilight pulled on her hips, trying to shove herself more deeply inside. In one powerful motion, Celestia pushed her flat onto her back, grabbed two overflowing handfuls of her lavender tits, and started going to town on her. Celestia's giant boobs bounced up and down in ways Twilight had never thought possible. All she could do was hold on for dear life as Celestia kept going harder and faster, her tongue lolling out of her mouth.

Celestia's bodacious ass slapped against Twilight's thighs each time she landed. It was so round, bubbly, and supple. It begged to be spanked, which Twilight did. Pins and needles ran through her hand from the sheer force she put into it. Celestia only gave it to her harder, pushing herself almost all the way up Twilight's achingly hard length before plummeting back down. Twilight pawed at her massive tits, squeezing them before they slipped from her grasp.

“Ooh, it's just so big!” Celestia moaned, cumming all over Twilight's dick. But she did not let that slow her down. She kept riding, even as her legs trembled beneath her. If Celestia was tight before, this brought a whole new definition to the word. Her pussy clenched and slobbered on the cock buried inside it, and she managed a good half-minute more before she collapsed.

When Twilight felt Celestia keeling over, she rolled onto her side, granting her a respite. She gently rocked her hips back and forth, helping her former mentor ride out her orgasm. After it ended, she pulled out and clambered off the bed. Her maredick throbbed painfully, jutting eighteen inches straight forward. “Sit up,” she commanded. Exhausted as she was, she still wanted to try something.

A slightly wall-eyed Celestia obeyed, swinging her legs off the edge of the bed. Twilight stalked toward her, putting on her sexiest gait. Her cock swayed pendulously from side to side with each step she took. She roughly grabbed Celestia's tits and squeezed them together. Then, she pressed her horsecock against them and pushed it inside. Celestia helped hold her tits in place as Twilight penetrated her vast cleavage.

To her amazement, Celestia's boobs swallowed her entire length with some room to spare. “I really love your tits,” Twilight said as she began to fuck them. They felt amazing around her shaft, and she had to push forward a good inch before her flared head met Celestia's chest. She planted her hooves shoulder-width apart and rolled her lover's erect nipples between her fingers as she tit-fucked her.

But Twilight was only limbering up. Being pinned and ridden for so long had left her feeling a bit stiff, and several minutes of making love to Celestia's voluminous breasts worked out all her kinks, which was convenient, as burying her entire massive cock inside a rack like this was a kink in and of itself. She pulled her cock out and placed it before Celestia's muzzle, prompting her to circle the fleshy crown with her tongue and gently suck on the head.

“Oh, Celestia,” Twilight whispered, her skin erupting with goosebumps. Reluctantly, she pulled her cock away and stepped back. “I've been wondering something.”

“Yes?”

“When ponies feel really good while having sex, they usually yell out your name, probably because you're so sexy,” Twilight said. “But... what do you say?”

Spreading her legs, Celestia laid back. “I think it's time you found out.”

That was all Twilight needed to hear. She grabbed Celestia's legs and shoved herself all the way in. Immediately, she closed her eyes and began to piston her hips back and forth in long, savage thrusts. She pulled herself all the way back to the head before slamming her rod to the hilt. Celestia tightened around her and howled with pleasure. “Oh, heavens above, Twilight, more—MORE!” she screamed.

Twilight grunted and railed her as hard as she could. Her tits bounced and flopped everywhere from her rapid thrusting. She held Celestia's legs against her sides, the knee joints on top of her shoulders. Celestia had taken one of her own tits into her mouth while wrapping both her arms around them. Twilight felt almost rabid as the heat and pressure inside her built and compounded.

Her cock afire with pleasure, Twilight kept going, slamming into Celestia over and over again. She could not say how long she held her unsustainable pace for. The feelings she had held at bay for so long reached a crescendo. “Oh, Celestia, it's too good. I can't hold it!”

Celestia let go of her boobs and propped herself up. “Cum for me, Twilight. Give me your huge, thick load.”

Twilight released her grip on Celestia's shapely legs and leaned forward, shoving her cock all the way inside, the bump atop her lover’s abdomen showing just how deep she was. She remained hilted for several seconds before she made erratic thrusts, feeling the last threads of her control sever. Her legs almost buckled beneath her as the biggest shock wave of ecstasy she ever felt crashed into her. She felt her horsecock throb, twitch, and pulse. Cum on her face! was all she could think, and she frantically pulled it out.

A rivulet of warm, sticky cum large enough to fill a teacup spilled from the head, pooling on Celestia's belly. Then, the dam really burst. Twilight's head snapped back, and she cried out as an enormous jet of futa semen arced past Celestia's head, blasting a pegasus-down pillow clean off the bed. She grabbed her spitting cobra with both hands, sliding them rapidly up and down its slick length and pointing it straight at Celestia as she felt another massive shot travelling through it.

The Magic of Friendship fountained all over Celestia's beautiful face, coating it in seconds. She felt Celestia's hands grasping her shaft, and together, they milked it, shot after shot spraying from its tip. Her hips jerked back and forth as she kept cumming, splattering her seed in Celestia's hair and onto her expansive boobs. Celestia opened her mouth and stuck out her tongue, taking several blasts in her hungry maw.

When Twilight's cum blasts slowed to a trickle, Celestia licked her lips and said, “That really was a lot! So much, and so delicious, my student.”

But Twilight felt like she had not came at all, despite how much she had just discharged. All she could smell was the evidence of her affection, but she needed more. Her cock was still painfully hard, and she crammed it in Celestia's mouth, pushing nearly half her length inside. “Oh, fuck—FUCK!” she said, holding Celestia's head in place by grabbing her horn. After a mere two thrusts, she felt herself erupting again.

Thick mouthfuls of cum blasted straight down Celestia's gullet and into her stomach. Twilight's hips bucked with each massive shot she fired. Excess cum leaked from Celestia's snout as Twilight pumped more and more inside her. A dozen more shots gushed from her before she released her and pulled out, giving Celestia's face a fresh coat of white paint. Coughing and spluttering, Celestia looked dazed when Twilight relented.

She needed more. With her cock still hard, she shoved it inside Celestia's pussy. She began giving it to her again, but she did not last long. This time, she did not pull out, letting her newest blasts of seed to gush deep inside her lover as her wings snapped open and magenta sparks flew from her horn, exploding like little fireworks. She moaned with sweet, sweet relief as she kept cumming. Celestia placed her hands on her stomach as it slowly expanded from the sheer volume of marecum inside it. It grew to the size of a good handful before Twilight was finished.

When she pulled out, large rivulets of cum spilled form Celestia's pussy, pooling on the tile between her hooves. Twilight clambered onto the bed and straddled Celestia, placing her huge cock between her tits. She grabbed two handfuls and used them to jerk herself off. It was not long before Celestia helped her by slurping on the head. Twilight promptly whinnied and came again, making Celestia's cheeks balloon from all the horse jizz pouring into her mouth.

Twilight popped her cock out of Celestia's mouth and covered every inch of her she could find. Her cum had formed a huge puddle around Celestia, soaking the mattress. Groaning, she placed her cock back between Celestia's boobs and used them to squeeze out every last drop of cum she had. Shot after shot sailed over Celestia's head, coating the tiles behind them and even splattering against the curtains.

Finally, utterly, spent, Twilight flopped backward, her drooling cock slowly deflating between her legs. They lay there for several minutes, basking in what had just happened. “I love you so much, Princess Celestia,” Twilight said, barely able to speak. Every inch of her felt sore, but incredibly satisfied. Her vision had gone slightly blurry from the cascading orgasms from her cock, a sensation she had never experienced, but one so amazing she could not describe how good it made her feel.

Celestia sat up, cum cascading down her voluptuous curves. “Never in all my years have I seen anypony cum that much. I thought I was going to drown!”

Twilight forced herself up and gave Celestia a feeble kiss. “You're so amazing, I couldn't help myself. I was really backed up...”

“I love you, too, Twilight Sparkle,” Celestia said, kissing her back.

“I hope you left some for me,” came a startling, familiar voice from behind.

Twilight turned to see Princess Luna stepping out from behind a curtain, wearing the same black satin dress she had earlier that night. Her right hand was slick with pussy juice. “Do not forget our bargain, my dear sister,” Luna said, staring at Twilight’s half-hard cock. “If I divulged the contents of Twilight Sparkle's dreams about you, then you would let me have a turn with her.”
