As a solar eclipse approaches, Celestia and Luna must deal with the increasingly sexual urges they receive from it.

WARNING: This story contains F/F sex and incestuous situations. Read at your own risk!

Princess Celestia and Princess Luna share everything; a home, inside jokes about the nobles, and even a hatred for broccoli. It's no exaggeration to say that they are closer than any other two ponies could ever be.

And they're about to get a little bit closer.

For the first time since Luna has returned to Equestria, a solar eclipse is approaching. And for the two sisters, that comes with an unfortunate reality: until it passes, the two of them will be struck by nigh-uncontrollable lust for one another, an itch that can only be scratched by wild, uncontrollable sex.

Can they get through the eclipse without giving in to these urges? Or are things about to heat up between the two Princesses?

This story was written in between seasons Two and Three. Edited by NickNack, surprisingly enough (although I doubt he remembers).

Eclipse

The clink of fine china when Celestia set down her tea seemed to echo throughout the room, breaking through the deafening silence that was boring into her ears. The marble-walled chamber was completely empty, barring the large telescope and the alicorn that was using it. With a calm smile, she peered into her private telescope, specially made for her by the finest astronomers in Canterlot. Sure, it was probably a bribe to get more funding, but who ever said she couldn’t enjoy a free telescope? Especially since her little sister, Luna, had returned from exile.

Celestia had never been able to control the night like Luna. There was a reason some scientists called it the Dark Age; the entire night sky just seemed dull and lifeless. With Luna in charge, though, everything seemed bright and new. Especially the moon. Celestia had figured that Luna would have begun to hate the heavenly body after being trapped there for so long, but it seemed quite the opposite. It reflected the sun much more powerfully than before, lighting up the night.

Tonight was no exception. Luna’s moon hung over Equestria, bathing it in its solemn rays. Celestia smiled as she zoomed out her telescope. “Oh, look!” she announced to herself, taking another sip of tea. “The moon is getting close to the sun! Looks like an eclipse is going to happen soon! I’m sure Twilight will be excited.” She shifted the telescope to the Ursa Major constellation.

That was when it hit her. As fast as a Wonderbolt, Celestia whipped the telescope back to the moon. “Wait,” she said, her voice filled with dread. “An eclipse?!” She backed up from the telescope, her eyes wild. Her mind raced at a mile a minute, trying to figure out what was happening. “And now that Luna’s back, that can only mean...! Guards! Guards, come quick!”

Wings spread, two alabaster pegasi in golden armor sprinted into the room. “Yes, Your Highness?” the leftmost one asked. “What’s wrong?!”

“I need you to find Princess Luna, right now. Do whatever you have to to get her here. Do you understand?”

“Yes Ma’am!” Both guards saluted before flying out.

Celestia grit her teeth and turned back to her telescope. If she was right (and she really hoped she wasn’t), then both she and her sister were in grave danger.

From themselves.

_-_-_-_

Luna shuddered as waves and waves of pleasure washed over her. “Oh, oh, yes... Please, do not stop...” Her sweet fluids poured out steadily, meekly surrendering to the powerful tongue working her quickly and efficiently. She hadn’t felt like this in centuries. The tongue began to probe deeper and deeper, each lick sending bolts of ecstasy up Luna’s spine. Her legs trembled uncontrollably. Her breathing was quick and shallow. “Oh, ooh!

“Oh, Celestia!”

_-_-_-_

The two guards stared at the Princess of the Night, who was writhing around under her dark-blue covers and muttering unintelligibly. “Um... Princess Luna? Excuse us.”

Her eyes shot open, revealing a set of turquoise pinpoints. She sat up and looked at them with a mix of anger, confusion, and relief. Her cheeks were bright red. “W-why does thou wake us from our slumber?” she asked, her voice echoing throughout the giant room and she claimed as a bedchamber.

“Princess Celestia has requested your presence immediately in her observatory,” they said in unison. “It sounded urgent,” the one on the left said.

Luna blinked. “Oh, well, fine. Thank you. Thou art dismissed.”

The guards exchanged looks. “But, Your Highness, we were going to accom—”

“We said, thou art dismissed! Go!”

Not daring to question the alicorn, both guards flew out quickly. Luna let go of the breath she had been holding before daring a look at her covers. They looked as normal as ever. “No damage yet,” she said. Taking a deep breath, she magically lifted up the blanket. Her fears were confirmed. Under her flanks, the sheets were soaked clean through with a familiar-smelling liquid. She sighed. “Hopefully the maids won’t question it.”

She lifted herself up, ignoring the strong tingle emanating from her loins. Small beads of what she hoped was just sweat rolled down her legs. Her body begged for release, but she wouldn’t give it that satisfaction. Not after that dream. She felt dirty, guilty for dreaming something like that. Really, her own sister! What was she, an animal? And she felt even worse after realizing that she had been aroused by it.

But yet, the dream felt almost... Familiar.

This was what Luna thought as she exited her bathroom, her hind legs and flanks quickly washed. Dismissing the thoughts, Luna began the trek to Celestia’s private viewing deck on the other side of the castle.

It was just a few minutes before dawn. Luna had just laid down to sleep a few minutes before, and, as such, was remarkably tired. She hoped that whatever Celestia needed could be taken care of quickly so she could get back to sleep.

The sun was just peeking over Canterlot mountain by the time Luna arrived at her destination. Luna sat at the foot of the staircase that led to the viewing deck that Celestia sat on, waiting for acknowledgement. But that acknowledgement didn’t come. The Sun Princess sat as still as a stone, looking over the land with anxious pink eyes. Even from her place below, Luna could tell that her sister was harboring troubled thoughts.

“Sister?” Luna offered. “We are here.”

Celestia turned around and looked at Luna. The younger sister could tell something was wrong. Instead of making eye contact like she usually did, Celestia stared at Luna’s hooves. Her mouth was curled into a small frown. “Yes, hello, Luna. H-how has your night been?”

Luna pouted. “Sister, what is wrong?”

“What? What makes you think something’s wrong? I just wanted to—”

“Thou art tapping thy front-left hoof against the floor,” Luna pointed out. “We know for a fact that thou only do that when concerned.”

Celestia opened her mouth to protest, but her words quickly turned into a labored sigh. “You got me.” Her face suddenly turned grave. “Luna, we have an emergency on our hands.”

Luna began to walk up the stairs. “Shall we call upon the Elements of Harmony?” she asked, standing at her sister’s side. A small blush crept over her face as their fur touched.

“No,” Celestia said, hanging her head. “I doubt they’ll be able to help here. Luna, can you sense where your moon is relative to my sun?”

“Let us check.” Luna’s horn lit up with a deep-blue glow. Her eyes shone with an ethereal white light. They stayed in this state for a few moments before dimming. “It seems to be approaching the path of the sun’s rays. I don’t see the problem here.”

“You mean... You really don’t remember?” Celestia asked, looking dumbfoundedly at her sister. Her face went red. Would she really have to explain this to her baby sister? It was so embarrassing the first time, all those years ago. She grumbled and looked away. “One day from now, we’re going to have an eclipse.”

“Is that significant?”

“Yes, it is, Luna. You see...” Celestia searched for the right words to use. “When eclipses, especially solar eclipses happen, it kind of triggers something in alicorns. We get these u-urges.” She had to choke the word out. “You know. These urges to... Make love. To each other. Yes.” Her entire speech, Celestia had avoided looking at her sister. Now, she dared a glance.

Luna was staring at her, jaw dropped. Her face had twisted into a strange mix of disgust and realization. Her shaking wings were raised slightly. “Thou art joking, correct?”

“No. I’m not.”

There was dead silence. Celestia twiddled her hooves. Luna simply sat, trying to comprehend what her sister had said. “Well,” she whispered, “that explains the dream...”

“What was that?”

“Nothing, sister!” Luna chirped, her wings now fully erect. “S-so, what do we do? Do we have to engage each other, or—”

“No!” Celestia practically screamed. “No. Listen, Luna: I know from experience that these urges are maddening. The closer we get to the eclipse, the stronger they’ll get, and the crazier we’ll become. But we have to get past it! It’ll only be two days. I suggest that we find ways to, ah, occupy our time until then.” She stepped away from her sister and began to walk down the stairs. “You know. Distractions.”

Luna turned. “Of course. But if we may ask... What did we do the last time this happened?”

Celestia’s entire body seemed to pinken. “Oh, uh, well. You had just discovered the act of, ah... masturbation, so there was that.”

“And you?”

“I’d rather not say.” Celestia shuddered as images of flagpoles and butter raced through her head.

_-_-_-_

After leaving her sister, Luna had been hesitant to go back to sleep, lest she have another dream. Instead, she decided to make an early morning visit to one of her favorite places in the castle: the Royal Libraries. There, she had found the head librarian, a pale-yellow unicorn named Bookmark, doing some early morning cleaning. After some mundane chit-chat, Luna had found herself thrown into a favorite pastime of hers: chess. Apparently Bookmark had been looking for something to occupy her time until the students and nobles started coming in.

Luna pushed her rook two spaces forward, and could only resist a yawn as she saw it be captured. Both her exhaustion and a strange burning sensation between her hind legs made it difficult to concentrate. She repeatedly shifted in her seat as she moved her queen to take a bishop.

The aging mare across from her held a hoof to her chin. Despite the fact that he cutie mark, an open book, had nothing to do with chess, she liked to think that she could compete with the best of them. And, lo and behold, here she was beating Princess Luna! Now, all she had to do was concentrate...

DING DING

“Hello? Is anypony here?”

Bookmark rolled her eyes before giving Luna a polite smile. “I’m very sorry, Your Highness. I’ll just be a minute.” She got up and began to walk to the front desk.

“Take your time,” Luna called after her. She slumped in her seat, laying her head on the board. She still shifted restlessly, unable to find a position that was comfortable. She didn’t dare to look down and check what she had done to the velvet pillow she sat on. Images of her sister’s most intimate areas flashed through her mind, causing her distress in more ways than one.

If only to take her mind off of it, Luna began examining the chess board. The board itself was made out of pure marble which was polished daily. The pieces themselves were made out of marble too. Luna eyed the white queen. The most powerful piece on the board. She bit her lip. So commanding, so domineering...

Just like sister...

She picked up the piece and began to probe it with magic. She looked it over with glazed eyes. It was so hard, so long...

Just like sister’s horn...

A few rows of books away, Bookmark had just finished helping a student find a herbology textbook called The Exotic Equestria. Now, she trotted happily through the rows, eager to resume her game with Princess Luna. Yet, as she got closer to the area of the library where the chess boards stood, she began to hear a strange, guttural moan.

“Ah, ah, ah! Oh, yes!”

“Is that the Princess?” Bookmark asked herself, speeding up. “Who is she talking to?” A somewhat pungent odor began to grace her nostrils. She walked into the clearing. “Excuse me, Your Highness, but what are you—”

What Bookmark witnessed there was enough to drop any jaw in Equestria.

Princess Luna, now streaked in sweat, was holding a enlarged white queen in her magical grasp. She swiftly shoved its flared top in-and-out of her marehood, covering it with her arousal. With her free hooves, she rapidly massaged the outer walls. Her legs felt as if they were going to melt under her hot juices. Her spine involuntarily arched itself, making her more open to penetration. Pleasure coursed through her with every thrust, leaving no part untouched.

She barely noticed as her tongue lolled out of her mouth. At this point, various fluids were seeping everywhere. Her fur was now wet and sticky. The normally purple pillow she sat on had been stained a light black. Luna bit her lip as she felt the queen going deeper, deeper, until she felt as if she would burst—

“P-Princess Luna!”

Luna’s glassy eyes snapped open at the offending shout. She quickly turned her head, only to see her aging chess opponent, who looked like she was about to lose her lunch. Just as quickly, she felt her libido fading, her orgasm lost.

“W-we, just...” she stammered. Her mind was racing so fast, she couldn’t even come up with a coherent sentence. All at once, everything caught up with her. “You!” she shrieked, jumping up. There was a small pitter-patter of liquid hitting the floor as she did so. She took to the air. Her eyes glowed with pure power, and her voice shook with rage as she said: “If thou dare telleth anypony about what thou hast seen this day, we shall see to it that the dungeons receive a new occupant!”

Bookmark swung her head up and down in some terrified form of a nod. “Yes, Your Highness!” She galloped away, most likely to hide under her bed and try to forget everything that had just happened..

Luna landed softly. She still hadn’t caught her breath. A small twinge of regret went off in her stomach. Of course, she would never follow through on her threat—even before she was banished, the dungeons were remarkably empty—but that didn’t make it okay. Especially considering the mare’s age. But, at the same time, she couldn’t let that get out to the public. If anypony found out what was happening...

Suddenly, she realized that she was still using magic. In her grasp was the queen, now four times its normal size. It was drenched in a lukewarm substance. She threw it backwards at the chess board, but then caught it in midair. She held it close and looked around.

All clear.

She walked off, hoping that nopony would question why she had a giant chess piece.

_-_-_-_

Dozens upon dozens of unicorn soldiers littered the training grounds, bunched up into small groups. They talked calmly. There had been rumors that Shining Armor, their captain, had reported that he would be temporarily unable to serve. And if he was gone, that meant that all their drills for the day were cancelled! No push-ups! No target practice! No back-breaking labor! They were fr—

“Alright, ladies, listen up!”

Instinctively, every guard on the field snapped to attention. About half then proceeded to instinctively groan after seeing just who was addressing them. It was Major Lockjaw, one of the meanest, oldest pegasi in the army (and in Equestria too, some guessed). He stood strong and proud at the north end of the track field, his scarred face twisted into an eternal grimace. He waited until every guard in Shining’s normal company had gathered in front of him before continuing.

“Now, you may have heard that Captain Shining Armor is gone for the day! That is true! But that does not give you permission to lollygag like some two-bit buffoons!” He paced back-and-forth along the front row as he spoke, daring anypony to make eye contact. “I have received direct orders, straight from Princess Celestia herself, exclusively for this Platoon A! At thirteen-hundred hours, you are to report immediately outside the Princess’ private chambers! Do I make myself clear?!”

Every soldier saluted. “Sir, yes Sir!”

Lockjaw’s eyes narrowed and his mouth shifted into a tight slit. “Good. Dismissed!”

_-_-_-_

Two hours later, just as the clock struck one, the thirty soldiers that made up Platoon A stood outside the great golden gates that led into Princess Celestia’s chambers. In particular, two newer soldiers hung back from the rest of the group, instead opting to talk amongst themselves.

“Huh,” Light Step said, looking around. “I wonder what the Princess wants with us? I hope it’s not an emergency or anything...”

The unicorn on his left, Flash Fire, rolled his eyes. “Yeah, right. Do you really think she’d call an entire platoon to her freakin’ bedroom if there wasn’t an emergency?” He grinned. “I’m guessing it’s at least a dragon. Maybe a hydra.”

Light Step’s heart skipped a beat. “Why would you smile about that?! B-Besides, that can’t be true! Didn’t they call in the Wonderbolts last ti—”

“Just think about it!” Flash interrupted, grabbing his friend’s shoulders. “Shining Armor, gone without a trace? Obviously, we’re being sent after whatever killed him!”

“Not quite, my little pony.”

All thirty unicorns spun to face the golden doors, which had somehow opened without anypony noticing. In the doorway stood Princess Celestia, tall and strong. Yet, her face looked slightly delirious. Her left eye seemed to twitch rapidly every few seconds. Her mane also seemed to be the slightest shade pinker. Everypony saluted as she walked forward. The crowd parted to make way for her.

She walked right up to Light Step and Flash Fire, the former of whom was sweating bullets. “I’m afraid you have the wrong idea,” she explained in a somewhat rushed tone. “The reason I called you all here today was for... An inspection, of sorts.”

Flash Fire puffed out his chest. “No need, Your Highness! I think you’ll find that some of us are A-O.K.!”

A few seasoned soldiers groaned at this. Celestia just smiled, showing all of her teeth in the process. “Well then, why don’t you go first? You know, just so you can get out of here faster.”

“It would be my honor,” he said, stepping forward. Celestia could barely contain her excitement as the unicorn walked proudly past his comrades, and straight into her chambers. She followed quickly after, a small spring in her step.

Light Step shuffled his hooves. “I have a weird feeling about this...”

The double doors closed quietly behind them. Flash Fire was a bit surprised; he knew that these were supposed to be Celestia’s private chambers, but he had expected something a bit more formal for an inspection. The room was wide and tall, with various stained-glass windows dotting the stone walls. In the center of the room was a lone pink canopy bed.

Flash had stopped to look, and nearly jumped when he heard the Princess’ voice right behind him. “Make yourself comfortable, young one. My bed is quite luxurious.”

“Oh, uh, sure.” Flash walked toward the bed and sat down. She was right; the bed was comfy.

Celestia began to circle the room, taking glances at the stallion sporadically. “So... What’s your name?”

Flash blinked. “Uh, Flash Fire, ma’am.”

“Rank?”

“Corporal.”

Celestia nodded. “Good, good... Got any family? Wife, kids?”

Flash laughed. “Naw, that ain’t for me. Ooh, but there is this one filly that works at the market...”

“Corporal Flash Fire,” Celestia said suddenly, taking a step toward him. “Are you loyal to your country?”

In response, Flash saluted. “Of course! I would anything to help Equestria!”

Celestia kept walking toward him. Her wings had begun to spread themselves. “And are you loyal to me?”

“Yes, Your Highness!”

Celestia stopped just a few inches in front of the bed where he sat. “Good.”

Her horn glowed a bright gold for just a moment, during which Flash felt himself being enveloped by a white light. When it was gone, he immediately noted that he felt much lighter. And, with a quick inspection, he realized: his armor had disappeared! Without warning, she reared onto her hind hooves and pushed him onto the bed. She then proceeded to get on top of him. With a smile and a blush, she began to nuzzle his neck, which had simultaneously gone rigid. “Can you keep a secret?”

Flash Fire dared a glance at the alicorn on top of him. “P-Prince—”

Before he could finish, Celestia had pushed her muzzle into his. Their lips locked into a tight embrace. Flash Fire didn’t dare to resist as the Princess pushed her long, flexible tongue past his teeth and began exploring his mouth. As she did so, she used her forehooves to massage, rubbing up and down his long gray torso. The blood which had been flushing his face began to fade a bit, as he felt it gathering in another place.

“Oh!” Celestia chirped as she felt his stallionhood poke her in the thigh. “That was quick. I sure hope you can last.” She lifted herself off him a bit to look at it. “A bit smaller than I had expected, but it’ll do.”

His psyche completely shattered, Flash decided to just go with it. He gulped as the white alicorn mounted him, the tip of his member just beginning to enter her.

Celestia bit her lip as he slid inside of her. Flash felt a wave of heat and pleasure as her moist lips touched against the head of his cock. He gasped, making Celestia giggle. The giggle quickly turned into a moan, however, as the stallion involuntarily shifted his hips under her. She began to slide up and down his shaft, her juices beginning to flow steadily downward.

But she was just getting started. She quickly picked up the pace, pressing harder and harder. In response, Flash’s breathing intensified. Pleasure coursed through him like waves, rushing through everything in their path. The alicorn’s pussy clenched tightly against his dick. There were satisfying smack sounds as Flash pumped under her.

Inwardly thanking whoever it was that decided the walls of her room should be sound-proof, Celestia began to moan more loudly. “Oh, yes, yes, yes!” Flash’s rod pushed forcefully against her walls.

For the first time since the start of their “encounter,” Flash Fire got a good look at Celestia’s face. Her cheeks were bright red, complementing the sweat beads that ran down her face. Her mouth was curled upwards into a devilish smile. His gaze eventually drifted downwards, where he quickly realized something that he hadn’t ever given serious thought before.

Princess Celestia was sexy.

Her body was solid and natural, not like all those plastic models you usually saw in Canterlot. Her coat looked like freshly-fallen snow, even during sex. Her wings were spread wide, touching the bed’s pink silk canopies. Not to mention her perfectly-rounded flanks, just full enough to put even more pressure on his cock while she rode him. He almost didn’t mind that she was moving so fast it felt as if he would break under her.

Luckily, Celestia seemed to sense this, and began to slow down. She panted hard. With a toothy grin, she stared down at him. “Let’s finish this, shall we?”

Celestia started pumping again. This time, with her magic, she slowly massaged his balls, fondling them in golden light. The pleasure surged through his veins, tearing through his mind. Flash felt the approach of his inevitable release. “P-Princess, I’m—”

His words were drowned out by Celestia’s ecstatic scream as she climaxed, his dick still in her. The sudden rush of her liquid just sped up his own orgasm. With a strong pump, the soldier shot his stream right inside of her, their fluids mixing. Shot after shot, he coated her insides with his cum. The creamy semen dripped down slowly.

She licked the saliva off her lips and lifted herself off of him with a distinct squelch sound. Their juices slid noisily on Flash’s stomach and penis as he let out his short final bursts.

“Holy... Celestia, that was amazing! I can’t believe—” He stopped when a dry towel slapped him right in the face. He levitated it off himself and looked at the Princess, who appeared to be wiping herself. “Celestia...?”

“I would rather Princess Celestia,” she said, wringing her towel. A multitude of substances flowed out and onto the floor. “Dry yourself off. Tell that stallion you were with that I would like to see him once you leave.”

Flash stared, mouth agape. “But, I, we... I just came inside of you! How can you just brush that off? What if you’re—”

“Pregnant? Ha!” Celestia said, rolling her eyes. She shot him an amused glance. “Trust me, if alicorns could get pregnant from normal ponies, there would be hundreds of little Celestias running around. I just needed to relieve some tension."

The stallion wanted to protest, but knew it was no use. He simply began to wipe himself off, grumbling all the while. “This is just college all over again...”

_-_-_-_

Luna sighed deeply. She had spent the past eight hours masturbating furiously to and with anything she could get her hooves on. Even the marble chess piece had been worn down to a nub. Yet, she couldn’t seem to get the itch to go away. No matter what, her thoughts always ended up drifting back to her sister. Her luxurious mane, her glorious wings... Her enchanting flanks...

“Bah!” Luna shouted, shaking her head. “It happens again! Et tu, mind?!”

Despite the unfortunate fact that by the fifteenth time around the pleasure had all but faded, she had kept at it. And as a result, she looked, in both her and her Abacus' opinion, dreadful. She was on her way to her private bathing room, a towel hung over her shoulder. It was hidden in the Western Wing by magics that not even the most elite of unicorns could detect. Luna was so happy when she came back from the moon, only to find that it had remained since she had left. It was where she went whenever she needed to unwind.

Her moon had just begun its ascent across the sky. The Princess took a few quick glances up and down the hallway. The coast was clear. With a flash of her horn, the wall she stood in front of parted, revealing a long downward staircase. She smiled wide and began her trek.

As soon as the door closed behind her, something felt wrong. The tunnel, usually somewhat chilly, was warm and humid. She neared the end of the staircase, and moved slowly to look around the corner.

The walls of the bathing room were a pure white. About halfway through the room, there was a small wall, which marked the boundary of the bath. The entire room was covered in a thick fog. In it, she saw the silhouette of somepony. Somepony who was using her bath!

Luna's eyes widened and she grit her teeth. She spread her wings, prepared to strike—

"Oh, these stains are so hard to get out!"

Her wings drooped. "Celestia?" she whimpered, walking into the fog. “Is that you?”

Celestia turned her head to Luna. “Luna?” Her face held a confused expression. Her mane, instead of its usual rainbow color, was a creamy pink. She held a large steel-wool brush in her magic, and was covered in suds and water. “What are you doing in my private bathroom? How did you even find this place?”

“Your private bathroom?” Luna replied, gasping. “This is our private bathroom! We have held it since the beginnings of Equestria!”

“What? I found this place about a hundred years after we built the castle!”

“Yes, because we made it!”

“Well...” Celestia said, rubbing the back of head. A smile flashed across her face. “Finders keepers, losers weepers!” She dived back into the waters.

Luna growled. “Celestia, leave! We desire to relax in our bath! The Windigoes only know how stressful of a day it has been...”

With a mischievous grin, Celestia lifted herself out of the bath, her backside facing Luna. She looked back at her and wiggled her rump. “If you want me, you’re gonna hafta come and get me!” She dived back into the water.

The dark alicorn blushed. “Celestia... Why must you mock us?” She laid her towel on the ground next to her. Hesitantly, Luna took one step into the water. She had to give her sister credit: the temperature was perfect, just the way she liked it. Confident that it was safe, she dipped the rest of her body in. The murky liquid went up to her chest, weighing down her fur and making it harder to move. She waded to the center of the wide tub. “Sister? We are waiting.” There was silence. Luna sat down. Celestia had to come up for air sometime.

As if on cue, Luna felt a tickle, right under the base of her tail.

Leaping up from the water, Luna screamed. “C-Celestia! What art thou doing with our rump?!”

Like some kind of beast, Celestia slowly rose out of the bath, licking her lips. “Mmm... Tasty! Luna, it’s been so long, I had no idea you were this good!”

Luna breathed heavily, not sure how to react to her near molestation. She could see it in her sister’s eyes: the lust had taken over. And with every minute passing, as the moon and sun neared, it would just grow stronger. Celestia’s self-control had never been very strong; that was evident enough with all the cakes she ate. Luna knew that she was in danger. She needed to make a break for it.

But how? Celestia was between her and the exit. Not to mention that the water was weighing her down, making it impossible to move correctly. And Celestia was now wading through the water, closer and closer. Luna took a step backward, only to find herself pinned against a wall.

“S-sister, please,” Luna choked out, closing her eyes. “This isn’t you! This isn’t...” Her protests slowly faded as Celestia came closer.

The elder’s natural heated seemed to fuse with Luna’s own. She pressed into Luna and began to nuzzle her neck before moving slowly upwards. As she climbed, she left small kisses. It wasn’t long before she had reached Luna’s muzzle, where she left a peck upon her cheek.

Luna held her breath; she didn’t want to do it! Yet... Celestia was so alluring...

She her head to face Celestia’s. The white alicorn was gazing at her almost deliriously. Her tongue, wet with saliva, stuck out a bit. Her pink eyes were glazed over with libido. At the same time, they seemed to hold some unknown quality that calmed Luna down. Her heart was still racing, but for a different reason.

With only a slight moment of hesitation, Luna moved forward to meet her sister’s mouth. They fit together like a key into a lock. As soon as they met, Celestia began rubbing against her. Their wings pressed into one another, begging to be set free. Their tongues wrapped around one another. With a forehoof, Celestia began stroking Luna’s underside. Luna recoiled as the pleasure erupted through her, just barely holding back an excited squeak. Between their mouths hung a thin strand of saliva.

Celestia’s bare hoof slowly brushed lower and lower along Luna’s stomach, until it reached an area that was warmer and wetter than all the rest. With the back of her hoof, she rubbed Luna’s engorged vulva tenderly. In return, Luna kept her sister’s tongue occupied with her own. Blood flowed through her cheeks. Celestia’s hoof went deeper and deeper into Luna’s marehood, massaging the walls and soaking in her fluids.

Luna felt like she had to scream as the titillation built up. Her sibling was moving closer and closer to her “special spot;” the one spot that drove her crazy with excitement.

Celestia’s hoof passed over it. Her hooftip even dug into it a little bit. Luna nearly bucked out her legs as the feelings washed over her. Her mind went blank for a moment, readying itself to give into the eclipse’s commands.

But as her brain restarted itself, she began to realize just what she was doing.

With a powerful shove, Luna sent Celestia straight into the water. The Sun Princess looked up at her younger with pure shock. “L-Luna? What are you doing?”

“What are we doing? What art thou doing?” Luna said. Her eyes looked like they were ready to jump out of her head. “Celestia, you said it yourself! We must resist! I know thou art stronger than this!”

Celestia blinked. “But... Nopony has ever refused to have sex with me!”

Luna forced her wings to go down and walked past her sister. “None of those ponies was your sister.”

With that, Celestia made no more protests. Luna lifted her towel onto her back and began her trek up the stairs, leaving her assailant to stew in the bath waters. Using her towel to extinguish the wet burning between her thighs, she held her head high and triumphant. She was a veteran of battle! Battle with the deadly, malicious...

She stopped for a moment. Her brow furrowed.

“Princess Molestia!” she finally announced to the empty hallway. She stuck her chest out, intensely proud of her hilarious pun.

_-_-_-_

As the morning sun rose over Equestria, its owner looked out uncertainly over the country. Celestia had been on edge ever since she had woken up. The eclipse was nearing, and her brain was doing flips trying to deal with the pent up sexual frustrations. After being denied the night before, it had gone through a state of semi-withdrawal. It was worse than the time she tried to give up coffee and sweets cold turkey. At least her mane had returned to its normal coloring.

The eclipse was set to happen at any moment. Every little sound made her jump. Under her fur, her skin felt like it was burning. The twitching in her eye, which had only gone away the day before after sex with her guards, was back with a vengeance. Every few moments, her vision seemed to haze over.

She held herself steady. “Come on, Celestia! It’s only for a little while longer. Just focus.”

She closed her eyes and began to travel to her happy place: The Land of Infinite Socks. She had founded it about five-hundred years prior, when a royally-appointed psychologist had determined that she was both criminally insane and unfit to rule, and, in a landslide election, a large pumpkin had been elected in her place. That served as the first and last time the citizens of Equestria got a taste of democracy.

In her mind, she was not Princess Celestia, but Queen Buttercakes III. She sat on her throne, minding over the various socks that scurried below her. The sun, which was in no danger whatsoever of being blocked out by the moon, sat high in the cloudless sky. A nice, refreshing glass of guava-mango smoothie floated at her side. She took a sip, and could almost swear she tasted it.

Suddenly, at the entrance of the throne room, a new figure came running in. Lo and behold, it was Princess Angelcakes IV! As always, her starry mane was done up into a cute ponytail, and her dark fur shone with some unseen light. Not to mention her dresses! Angelcakes always wore the fanciest, most exquisite clothes in all of the land.

Yet, as she came closer to the throne, Buttercakes saw that something was different. Instead of a golden dress, Angelcakes seemed to be wearing black leather. And it wasn’t just any type of black leather—no, this seemed to wrap around her like a snake, making the parts of her body that were bared stick out. The bottom just barely covered her most intimate areas, and was tight enough to provide a decent idea of what lay there.

Buttercakes could only stare as her younger raced up the steps to her throne. Perhaps it was just the noontime sun, but Buttercakes was beginning to feel uncomfortably warm. Especially as Angelcakes, a grin on her face, climbed onto her lap. The leather was sweaty, and only served to rub seductively against its wearer.

“What is this?” Buttercakes asked, shifting in her seat. She closed her eyes, if only to escape the hold that Angelcake’s teal eyes had put her in. When she opened them, the dark pony had something red and spotted in her mouth that seemed to be making it difficult to speak.

“Celestia!”

Snapping out of her dream gone awry, Celestia spun to face the source of the noise. Princess Luna had walked in with an anxious look on her face. Thankfully, she wasn’t wearing a bondage suit. Neither mare could look at one another. Luna sat at her sister’s side without a word. They both simply stared forward, looking at Equestria’s sunrise.

Finally, Celestia broke the silence with a sigh. “Luna, what are you doing here? You know it’s not safe. Especially after last night—”

“Sister, it’s okay,” Luna interrupted quickly. “We forgive you. We understand that you were just running on instinct, and that you cannot be held accountable for what happened.”

“Oh. Really? Thank you, Luna. But that still doesn’t mean it’s safe!”

“The two of us entered this together, and we’re enduring it together. We trust you, Celestia.” She looked up at her sister. “And look! Your mane is has even transformed. Just like we said.”

Celestia opened her mouth to argue, but found herself stunned into silence as an intense, albeit familiar burning began to pass through her. Yet, this time, it was much more powerful. It was all she could do not to scream out in pain. Evidently, Luna could feel it too; her wings had shot out and her face had contorted itself until she looked as if she had just been attacked by a lemon.

Her eyes shot up to the morning sun. It was as she feared: the eclipse was beginning. The very edges of her golden orb were blackening. Down below, the city of Canterlot was just waking up. Equestria had been alerted that an eclipse was eminent, and they had prepared. Special glasses were constructed for anypony that wanted to watch the eclipse. The few ponies that were already awake were watching the moon pass over the sun happily, unaware that their princesses were going mental in their castle.

Luna was literally rolling on the floor, clutching her groin. “Sweet Windigoes, we feel as if we’re being burned alive!”

Celestia could barely keep herself standing. She was breathing so fast, it felt like her face was vibrating. Her loins tortured her, begging her to simply go over to her sister, and force the younger’s horn inside. But she couldn’t. She knew it would pass. It was just a matter of waiting.

About a third of the sun was covered by the time Celestia felt her knees beginning to buckle beneath her. Luna had managed to stop screaming, but was still sweating profusely. Her entire body was screaming at her. It was like the millennia of heat that she had missed had just combined into one force and invaded her body. She couldn’t stand it. She limped her way back from where she had rolled to.

Celestia managed to hold her shaky legs up. “Only a few more minutes left!”

“Yes, I can see that...”

“Oh, Luna!” Celestia cried. “I know it’s been hard, but we’re about to make it! We’re gonna show this eclipse that it can’t control us! We are stronger! We are princesses! We are—”

Without warning, Luna grabbed her sister and kissed her.

Celestia was shocked, but didn’t resist. Luna tipped her head to the side, allowing her to go deeper into the elder’s mouth. Her tongue slipped easily through Celestia’s wet lips. Her eyes were closed as she submitted to the passion. The pain that had been torturing them both seemed to vanish. Their body warmth began to mix as they got closer, their chests pressing against each other. Luna slowly swirled her tongue in the other’s mouth. Celestia ran a hoof through her sister’s starry mane. Luna took in a deep breath, taking in Celestia’s alluring scent; it was like that of freshly-picked flowers on a summer day. Not to mention the obvious scent of her arousal.

Luna pulled away. As soon as she did, the pain began to return. She was practically panting. “I’m sorry.”

Celestia smirked, her protests abandoned. “For what?”

With a newly found smile and an adrenaline fueled burst of strength, Luna pushed Celestia to the ground. The bigger alicorn withheld a a yelp as Luna slowly moved down her torso, nuzzling the soft white hair with her nose. She slowly climbed downward until she reached Celestia’s wet folds. She breathed in its fragrance deeply, shuddering in delight. Celestia squeaked as her sister pressed her tongue flatly against her sex.

This was quickly followed up by a firmer, more passionate lick. Within a few moments, Luna had her muzzle fully pressed into Celestia’s pussy, liquid flooding her mouth. She rapidly cleaned her sister of the sweet wetness that was flowing just as rapidly. The taste of her danced across Luna’s tongue, just encouraging her to go faster.

Celestia bit down on her lip, hard. Slowly but steadily, Luna moved her tongue inward, just past the alicorn’s folds. Luna just teased her with quick, circular licks, each one sending a short spasm through her sister’s body. Her muzzle was completely drenched by the time she pulled out.

“What are you doing?” Celestia asked through labored breaths. She looked up, over her torso at Luna. “Aren’t you going to finish? The eclipse isn’t even half over yet!”

Luna didn’t speak as her horn lit up with an intense blue light. A smile passed over the faces of both ponies as they realized what was next. Luna moved back a bit, allowing her sister to stand. Celestia proceeded to turn around and put her chest and head close to the ground, leaving only her hindlegs and rear still standing. Fluids dripped down her legs. In response, Luna pointed her horn straight at Celestia’s pussy and began moving in.

The pointed edge entered easily. Celestia winced a bit as she felt it poke her inner walls, but the sting quickly passed and was replaced by a familiar pleasure. Luna felt it too; despite their hard exterior, unicorn horns were actually quite sensitive to the touch. Ecstasy coursed through her as each individual ridge passed Celestia’s lips. As she got deeper, her head came closer to Celestia’s crotch, letting the scent that she loved so much enter her nostrils.

Celestia clenched her eyes shut as the horn became wider near the base. It pressed against her walls, stretching and forming them to fit Luna’s horn. She could feel Luna’s starry mane beginning to brush against her flanks, signifying that the entire horn had fit in. Celestia felt it deep inside of her. It coursed with energy, just making the experience that much more pleasurable. Her warm juices circled the horn and her muscles involuntarily clamped down on it.

That was when Luna began to pull out for the first time. Her ridged horn dragged tightly inside of Celestia. It was glowing even brighter than it had been when she had slid it in. A thick strand of Celestia’s arousal hung from the tip, threatening to fall to the marble floor below. Luna stared at it in awe.

“What are you waiting for?!”

Luna was struck out of her admiration by Celestia’s voice. The white alicorn was staring back at her with both an impatient look and a severe blush on her face. “Fuck me!” she screamed.

With a quick nod, Luna once again pointed her horn at Celestia’s entrance and slowly entered. Both ponies were once again caught in the throes of ecstasy, but a new sensation quickly entered them as Luna began to thrust her horn, slowly at first, but quickly picking up speed and intensity.

Luna hadn’t done something like this in... Actually, she had never hornfucked somepony! Before her banishment, all her mates had been stallions, none of whom seemed particularly interested in anal, so she had never gotten the chance. And now that she was actually doing it, it felt amazing! She never wanted to stop!

Celestia, on the other hand, had done this many times before. However, none of those times were as good as this. Her hindlegs trembled with each thrust. Her back arched, just letting the horn slide in deeper. She knew that the guards outside could probably hear them, but she didn’t even care. All she knew at the moment was that she was feeling things which hadn’t been felt in millenia.

Yet, it wasn’t to last. A deep disappointment entered her as she glanced at the sky. The sun was completely covered, meaning that the eclipse would be ending soon. Apparently Luna knew this too, as she was now pushing harder and harder with each thrust. Celestia felt her hindlegs being lifted off the floor. Her body screamed for an orgasm, and it was about to get it.

“...Aaaaaaaah!”

Celestia’s ears perked up as she heard her sister’s scream. Suddenly, a new feeling entered her. It was a hot liquid, and it seemed to be coming out in short bursts, completely flooding her. Of course, she knew immediately what it was: magiculation. Apparently Luna couldn’t match up when it came to endurance.

That was all she needed to reach her climax. Her liquids mixing together with Luna’s, the muscles in her marehood began to pulse even more rapidly, gripping Luna's horn harder than ever before. She banged her hooves against the floor. She came hard and fast, drenching Luna’s mane in the process. There was a loud splatter as the excess juices fell to the floor. Luna, still recovering from her own orgasm, mustered up enough strength to give one final thrust.

Once Luna pulled out, Celestia immediately collapsed onto her back. Her moist lips were still flowing a bit, letting both the princesses’ orgasms out into the air. Luna’s legs wobbled a bit, and she fell forward, her snout landing right in Celestia’s wet crotch. Both Celestia’s clear fluid and Luna’s glowing blue liquid magic ran down the length of her horn, dripping into her mane. They were both sweating profusely.

Luna lapped up a glop of cum and lifted her head. “Sister, are you alright? Were we good?”

Celestia let out a delirious laugh, and didn’t stop until she had run out of breath. “Oh, you were perfect, just perfect! I’ll be feeling this for a while!”

Luna looked to the sky. As she had predicted, the eclipse had all but passed. Sunlight was once again making itself known throughout Equestria. Both alicorns seemed to shine with the amount of wetness they had on them.

“That... That certainly was strange, was it not?” Luna asked with a sheepish grin.

Celestia tried to get up, but just fell again. “Yes, yes it was.” Accepting that her legs wouldn’t be working for the time being, she settled on simply turning her head to her sister. “What do you think would happen if everypony found out the ‘Great and Powerful Alicorn Sisters’ were doing it in the castle?”

Luna blushed and shuffled her hooves. “Oh, we don’t know... I mean, us alicorns are such important creatures! We can only imagine—”

That was when it hit her. Her eyes became as wide as dinner plates.

“S-Sister...”

“Yes, Luna?”

“This happened because we are alicorns, yes?”

“Yes. What of it?”

“...What happened to Cadance?”

Celestia’s smile dropped immediately. “That’s a good question, Luna. I, uh, don’t know.” A deathly silence passed over the two. “Well,” the Sun Princess resumed, looking into the sky, “I’m sure she’s fine. I mean, she doesn’t even have a sister! What could happen?”

_-_-_-_

Coast’s clear.

Shining Armor stepped lightly as he made his way over to the silver suit of armor that sat on the other side of the room. His entire body ached as if he had just fought off the changeling queen herself. His love, Cadance slept restlessly in their posh, king-sized bed. Hopefully he could get dressed and get out without having to talk to her.

It wasn’t that he didn’t want to talk to her; he couldn’t get enough of her voice, as sweet as chocolate and as soft as velvet. But, recently, she had been... Different. Aggressive. Demanding. Short-tempered. At first he had been worried that she was pregnant, but a test had shot down that theory. Then came the theory that Chrysalis had returned; yet, they were still able to activate the love spell, so that couldn’t be it.

And that wasn’t to mention the sex.

He hadn’t been this tired since their honeymoon. Just walking made his crotch throb as if it had been bucked at point-blank range. He breathed a sigh of relief as he put a hoof on the armor. So far, so good.

With practiced stealth, Shining put on his uniform. He grasped his helmet in a light red aura and headed for the front door of their castle suite. He kept his eye on the alicorn as he left the room. There was dead silence as Shining tiptoed to the door. Not even his hoofsteps made a sound. He had his gaze trained on Cadance until the room was out of sight, before smiling and turning to the door.

Cadance was standing in his way, staring him right in the eye.

“Ah!” he yelped, jumping backward. “C-Cadance! How did, did you—”

“Dear,” Cadance said in a voice that resembled a hiss. “Where are you going?”

Shining Armor forced a smile onto his face. “I was just going to work, sweetie!”

Cadance laughed. But this laugh wasn’t like any she had ever given before. It was loud, long, deep. It seemed to go on for ages. That was why it was just that much more unsettling when she stopped suddenly and affixed her husband with a glare that could melt ice. “I don’t think so.”

“Sweetie, please! I’ve already missed a day! I can’t just abandon my company!”

She took a step toward him. “I think you can.”

He took a step back. “This needs to stop!”

“No! We can’t! Not until this damned itch goes away!” Cadance spread her wings, easily dwarfing Shining’s already large stature. A crazed look took hold on her face. Her eyes were on fire. She laughed maniacally, and Shining could have sworn he heard thunder.

“It’s Cadance time!”

“No, sweetie, no!”
