Author's Note

Finally some bucking clop in this story. I promise there will be more near the end too.

Princesses, you can't buck in here! This is the throne room! (clop chapter)

Celestia and Luna both sweated intensely, elation marking their features as they continued their intimate activity. Celestia let out a cute laugh, as her sister stuck her tongue out of the side of her muzzle in concentration, putting the finishing touches on a golden rune in one of the many spell constructs now lining the floor. Celestia released her own magic. Examining the final outer circle, she nodded in satisfaction and then stretched out her body to release her tension; earning her a few satisfying pops.

Luna’s work completed, she joined Celestia in stepping outside the circle where they admired their work. This was a magical circle they had not drawn in over a thousand years. The spell weaving had to be incredibly precise as the leylines grew so close as to almost cross; risking damage to the lines or even explosive mana-feedback to the caster’s horn. Normally, what would have been weaved and crafted carefully over the days leading up to a Sun Celebration, Celestia and Luna had managed to finish in a few hours, a true testament to their magical skills.

If properly drawn and charged, the circle would help magnify Celestia’s already formidable alicorn magic. The sun had in recent years entered a period of increased activity and shined that much brighter in the sky. During these ten year long periods, what pony astronomers had dubbed a “Solar Maximum”, Celestia was at the peak of her natural magical capacity.

Back in the days before Luna’s banishment, Celestia would hold numerous Sun Celebrations during these ten year cycles. These cycles when combined with the proper magical circle, allowed Celestia to connect more closely with her orbiting star, filling her with a near limitless amounts of magic, which she would then use to enchant herself during the celebration. If everything went correctly, Celestia’s chosen mates would quicken with her enchanted seed, eventually giving birth to a healthy foal. These foals, always mares, were known as the "Star-Kissed Daughters of Equestria". They were great gifts bestowed upon loyal mares seeking to be mothers of heroines that would serve the kingdom in times of turmoil.

These "Star-Kissed", without fail became ponies of great renown, often reaching the peak of whatever race they were born of, be it becoming one of the fastest pegasi, the strongest earth ponies, or the smartest unicorns. And now Celestia would attempt to give this precious gift of life to her sister.

Celestia and Luna continued to examine the circle, both were deep in thought, but it was Luna who eventually broke the silence. “Sister, it does not escape our notice that not only have we entered a Solar Maximum, but our moon is also at its fullest, even now from behind the horizon we can feel the thrum of power that flows into us from it.” She gave a slight smirk. “It seems to us dear sister, that this has been planned, and well in advance.”

Celestia gave out a cry of mock indignation. “Alright, Luna, you caught me!” she smiled. “I have given this much thought since the nightmare was driven from you several years ago.” she sighed. “I know how deeply you’ve always desired to have a foal…”

Luna gazed at her sister, her face unreadable. “Sister, we know what you offer, but you do not have to worry about us embracing the Nightmare again, even if we can never be with foal of our own. Are you sure you wish to do this, to give one such as us this incredible gift?”

Celestia wasted no time in responding. “Luna, you have no idea how much I want to give you this. She glanced towards her sister, a smile on her face. “I am the mother of Equestria, yet I’ve not planted a foal into a mare nor carried one in my belly for generations.”

Celestia licked her lips as her smile once more twisted into one of hunger. “If you came across a starving pony in the desert would you not give them bread to eat? And how much more inclined would you be to help if said pony was of your own family?”

Celestia turned toward Luna, towering over her at her full height. Her smile was now one positively dripping with hunger. “Luna, I am a starving pony in a desert that has stretched out before me for a thousand years… Now would you deny your sister her meal?”

At that proclamation a powerful, meaty slap echoed throughout the throne room.

Celestia, her sexual appetite peaking, had dropped her concealment spell, and an absolutely massive pole of flesh could be seen beneath her barrel, the eye-wateringly large cock pulsed in time with Celestia’s increasing heartbeat, and even from a few steps away Luna could feel the heat washing off of it and could smell the musk that now began to spread around the room like morning fog.

Luna instinctively licked her own lips. It wasn’t the first time she’d seen Celestia unconcealed, back in the early days of the kingdom it was a common sight, but being this close…Her eyes widened as she could now tell her elder sister had been denied release for centuries.

Celestia’s cantaloupe sized balls were practically shuddering with production, and the veins that rippled across her shaft were shifting as blood pulsed through them. Celestia was painfully erect, and here she had offered herself to Luna, practically begging Luna to ease her suffering.

Deep inside Luna’s mind something finally clicked, perhaps it was her many lifetimes spent serving as a bringer of comfort to her ponies, perhaps it was mating instincts snapped to attention by Celestia’s now commanding pose. Whatever the reason, Luna had made up her mind. Celestia needs our help, and by the gods do we want a foal inside us!

Luna had hardly even so much as nodded her acquiescence before Celestia had closed the gap between them and mashed their muzzles together.

Luna didn’t stand a chance against her older sister, simply letting her tongue be dominated by Celestia’s aggressive motions. A satisfied growl left Celestia’s throat as she used her wings to pull Luna into an even tighter kiss.

By now Luna’s legs were practically shaking as her whole being was consumed by lust. A loud splashing could be heard coming from behind Luna, a veritable deluge of fluids were now running down the smaller alicorn’s hind legs, causing her cheeks to flush even more as Celestia smiled through the kiss. She broke it for a moment to tease her. “My, my, dear Luna, it seems I wasn’t the only one in need!”

“Shut... Shut up!” Luna stammered, her cheeks practically on fire at this point.

Unlike normal ponies, Celestia and Luna didn’t go into estrus on a seasonal cycle, instead their heat was controlled entirely by the position of their respective celestial bodies, for Luna, this peaked during a full moon, and for Celestia, the much longer period of a Solar Maximum. For them to both be at the peak of their cycles with this much repressed sexual energy...

Luna needed this dammit! She swallowed her embarrassment, and much to Celestia’s surprise, Luna now aggressively mashed her muzzle into Celestia, continuing their heated battle of twirling tongues and swirling saliva. This time however, Luna didn’t concede, instead she tried to lay low the solar oppressor; conquering through her speed and dexterity. Whereas her elder sister Celestia was undoubtedly gifted in seeding life into mares, Luna had honed the skills of her tongue and body for pleasing her subjects over lifetimes of experience. Luna was a master of the sensual arts, and it was time she finally demonstrated this to her over-aggressive lover.

Luna’s horn glowed a cool blue as she weaved magic between them, spreading under Celestia’s belly, her magic encompassed Celestia’s impressive balls before giving them a slight tickle and then a rough pull. Celestia was caught completely off guard, breaking the kiss in a surprised whinny she kicked one of her hind legs in an instinctual effort to dislodge whatever had gripped her sensitive testicles. Seizing the moment, Luna wrapped her magic around the solar princess and none too gently flipped her onto her back with a loud crash.

By this point, all the noise had drawn a sizable group of palace staff into the throne room, all of whom were completely entranced by the sights before them, not helped by the massive amounts of alicorn pheromones that were seeping into their brains, gripping their minds with lust. Mares in the group soon went into out of season estrus and began dripping onto the marble floor, while the males of the group could no longer constrain their impressive flesh spears as they smacked into their bellies with an audible slap, slinging globs of pre across the floor.

Luna now straddled Celestia looking down at her with a mixture of lust and smug satisfaction. The sheer hunger on Celestia’s face was now tinged with a small amount of pleading and she mewled in undisguised need. Luna’s ears suddenly swiveled upward hearing meaty smacks from around the room. Looking back up she gave a small smile as she noticed the room was now practically filled with lust-consumed guard ponies. “It seems we have an audience dear sister… good.”

Luna looked down at her sister with a small smirk still on her muzzle. “Forgive us, we simply wished to show you that it is we, not you who are the master of these carnal arts. Now we shall end this farce and begin in earnest!”

Luna slowly crept down Celestia’s barrel laying gentle kisses on Celestia’s impressive shaft, leaving streaks of her saliva she traveled; only stopping by the massive testicles to inhale a satisfying breath of musk. Celestia whimpered up above in unrestrained need the entire time as Luna continued downward.

Finally Luna reached her prize.

Celestia’s vulva folds were an almost pristine pink surrounded by dark white fur, it reminded Luna of beautiful lily petals, promising the life and bounty of spring. It was too bad she planned to absolutely destroy it. She dove in muzzle first past the outer folds causing Celestia to yelp at the sudden intrusion.

Celestia had not been touched intimately down there for nearly a millennia, sure she had tried a few flings with her braver guards over the years, but her guilt over her banishment of Luna had always stopped her before things got too physical. Now she had no such guilt holding her back and she was practically bucking herself into Luna’s muzzle begging her for more stimulation.

Luna sensing Celestia’s needs, obliged immediately using her tongue to dive even deeper into Celestia’s blazing hot pussy, sliding around every sensitive cranny as her innate skills in pleasing mares came to the forefront, she listened for each whinny of pleasure, watched for each twitch of a hoof or wink of the clit to guide her ministrations, never hesitating or slowing in her onslaught as rivers of marecum slid past her muzzle and pooled on the floor beneath them.

Celestia was well beyond the breaking point now, her mind had mostly become a cloud of pleasure and all she could do was twitch and whinny as Luna took complete control of her body.

Celestia’s incredible libido combined with a legendarily long dry spell meant she was about to explode. Even in this state however, Celestia was still somehow able to use a portion of her willpower to stop even a single drop of cum from releasing from her over-sized testicles.

Luna sensed Celestia’s tensing, her inner walls attempting to clench down on Luna’s tongue. She slowly withdrew her muzzle from Celestia’s folds and quickly began prodding her nose against Celestia’s massive clit as it winked out into the open air. After a couple of prods, Luna took the nub into her mouth and gently bit down.

Celestia’s body instantly seized, she had gone beyond the peak and rocketed past the sun, exploding into a supernova of an orgasm. She screamed. She screamed so loudly that the massive palace windows began to spiderweb with cracks. Several of the nearby guards were driven to their knees and at least one, driven by both lust and the sudden shock came, spurting a liberal amount of life-giving fluids across the pristine rug running through the middle of the room, before promptly passing out, a smile adorning their muzzle.

Celestia continued to twitch and writhe for a few more moments under her younger sister. Luna had shown mercy by swiftly releasing the throbbing clit from her mouth, but the damage was already done.

Celestia was a broken mess of a mare, drenched in sweat, her barrel heaved with powerful breaths, broken occasionally by a light cough or whimper. Her beautiful multicolored mane and tail, once radiating and floating on an ethereal breeze, was now completely damp and clung to her fur like a wet towel.

Luna surveyed the destruction and saw that it was good.

She giggled slightly while thinking to herself, If I had only tried to take Tia’s throne this way. Her thoughts were interrupted as Celestia slowly stirred beneath her, her eyes fluttering and trying to focus.

Luna openly laughed at the display before finally crawling back onto her hooves and off her now thoroughly satisfied- hmm, no that wasn’t true, now was it? Luna thought to herself. In the midst of their passions, she had failed to notice that despite her window cracking orgasm, Celestia’s more noticeable parts still remained turgid and unyielding. How did her stallionhood not find release from that? Luna’s inner monologue gasped, could any pony have so much willpower?

Celestia, now finally back in control of her faculties glanced from her position splayed out on the floor and took note of the casualties -Twilight had not developed her keen sense of organization and observation from nothing- She quickly made mental notes for therapy sessions for several guards, set aside bits for extra cleaning of the floors, repairs for the damage to the marble beneath her and restoration of the cracked windows. Finally she took stock of perhaps the most important thing, and let out a satisfied breath; her cock remained painfully erect and not a drop of fluid had been spilled.

Energy flowing back into her limbs, Celestia cracked a smile as she licked her lips and thought to herself, You’ll pay for that one Luna. Revenge after all is a dish best served warm...and deep.
