Chapter 1

Luna walked down the halls of Canterlot Castle, trying her best to ignore the heat coming from her loins. She wasn’t exactly in heat, but she definitely needed that itch scratched. Imagine her frustration when she found that her sister had thrown away her porn collection while she was away. She had kept everything else. She’d even kept the first dress she had ever worn even though it would never fit her again. She huffed in annoyance as she rounded a corner and approached one of her night guards. He stiffened up as he noticed her, a sign of the diligence he had in his duties.

“Guard.” She said simply.

“Yes, Princess?” He asked.

“Pray tell, where dost one find pornography in these times?” She asked.

The guard’s eyes widened as he looked over at her skeptically, trying to determine whether her question was a serious one or not. Was this some sort of test? Had she found his porn stash and decided to interrogate him about it? He decided that the safest answer would be the best thing. He didn’t want to lie to his Princess, but it was his only hope at coming through this with his career intact.

“I…uhhh…wouldn’t know, Princess.” He lied, blushing lightly in embarrassment.

“Surely thou hast utilized a tool such as this before?” Luna asked, tilting her head to the side in confusion. “Thou art a stallion!”

“Nope, not me.” He said, his mouth scrunching has he tried his best to hide the fact that he was lying.

Luna looked at him suspiciously. She wasn’t fooled for a second, but decided to drop the matter.

“Very well.” She said. “Continue your duties.”

“Yes, Princess!” He said, giving a grateful salute.

Luna huffed again in annoyance and started walking down the halls again. She decided that a visit to the library was in order. If her guards were unable to help her, then she just had to take matters into her own hooves.

“Excuse us, Ms. Quill?” Luna asked, directing her attention to the young Pegasus mare behind the counter.

“Yes?” She said, turning around slowly. Her eyes widened as she realized the voice belonged to Princess Luna.

“Oh, my!” She gasped. “Princess! Welcome to my library! What can I do for you?”

“We wish to be directed to the erotic arts section.” Luna said calmly.

The Pegasus mare’s eyes widened again.

“E-excuse me, Princess?” She asked frantically.

“The pornography.” Luna said. “Where is it?”

“P-pornography?” The mare said nervously.

“Yes.” She said simply.

“I…” The mare froze, her brain appearing to be broken.

“Well?” Luna asked expectantly.

“T-this is a library…” The mare said, shaking her head. “This is not the appropriate place to…procure such things…”

“Oh?” Luna asked in surprise. “In our time, libraries were the primary place where such materials could be found.”

The mare said nothing, simply staring at her wide-eyed.

“No matter.” Luna said dismissively. “Well then, where should we go to find such a thing?”

She opened her mouth but no sound came out. She reluctantly closed it, not knowing what to say.

“Well, citizen?” Luna asked menacingly. “Art thou refusing an order from thy Princess?”

“N-no!” The mare said defensively. “I-I’m just surprised is all! I didn’t think that you of all ponies would enjoy that sort of thing. D-does Princess Celestia know?”

“Surprised that we have needs that need satisfying?” Luna said bitterly.

Luna huffed in annoyance.

“Our sister hast destroyed all the pornography we used to own, so now we must procure more of it in order to satisfy ourselves.”

The mare blushed profusely.

“A-as you wish, Princess.” She said, bowing her head slightly. “You may find such material at The Naughty Mare downtown near Market Street.”

“Thou shalt fetch it for me.” Luna said.

“M-me?!” The mare stammered nervously. “B-but I-”

“You shalt bring it to our chambers tonight in a concealed bag.”

“B-but, Princess - ”

“Art thou refusing an order from thy Princess?” Luna said again, this time sending her a glare that sent shivers down her spine.

“N-no, Princess…” The mare said, lowering her head in defeat.

“Make sure to bring us a variety of material so that we may find something we enjoy.” Luna said, walking out of the library without any further threats.

Luna was brushing her mane after a long day in court. She had just gotten out of the shower and was very much anticipating the arrival of her new pornography. She just hoped that the mare wouldn’t disappoint her. She had wanted to go to the shop herself, but she was still unfamiliar with the streets of Canterlot and she had a busy schedule so she had no choice but to enlist the help of one of her ponies. A sudden knock on the door filled her with giddy glee and she trotted out of her bathroom to answer the door.

As she expected, the young librarian stood there with a bag. Luna casually lifted a large sack of bits over to her and she gladly accepted them in exchange for the bag.

“Princess, this is far too much!” The mare exclaimed as she felt the weight of the sack of bits.

“We do not care.” Luna said. “We are just glad to finally get relief.”

“E-enjoy, Princess…” The mare said sheepishly, bowing out.

Luna closed the door behind her and trotted over to her desk, opening the bag with great anticipation. She frowned as she laid eyes on the first cover.

“Celestia’s Secret: Chocolate Sauce Edition” She read aloud.

The cover of the magazine had a big picture of her sister covered in chocolate. She opened the magazine to a random page and nearly dropped it in shock. Her sister was lying on her back on a table in what looked like a bakery. Her back legs were spread-eagled, showing her open pussy covered in chocolate sauce.

“W-what is this?!?!” Luna cried.

She slammed the magazine shut frantically and tried to block the image from her mind. She grabbed another magazine from inside the bag and pulled it out. It was another Celestia’s Secret magazine. She put it aside and pulled out another magazine. And another. She frantically emptied the entire contents of the bag onto the table, desperately trying to find something other than a Celestia’s Secret magazine. Her worst fears were realized when she got through all of the magazines and realized that they were all different issues of Celestia’s Secret.

Maybe they’re not all about my sister. She thought. Maybe I just opened to the wrong page.

She tentatively picked up one of the magazines in her magic, staring at the cover.

Celestia’s Secret: Ball-Gags and Paddles Edition.

She didn’t read it aloud that time, but the title was burned into her memory. Slowly and reluctantly, she opened the magazine to a random page. She stared slack-jawed at what she saw. Celestia was mounting a fake bull, her tail raised and her rump red as a red paddle hovered in the grip of an unseen pony’s magic.

How could our sister agree to be in these magazines!? She thought frantically. Hast she gone mad!?

It was then that she realized that the page had a fold-out section. She pulled the fold out and was shocked to find that the previously unseen pony that had been holding the paddle was her.

“Wha-How?!?!” Luna exclaimed.

She knew for certain that she did NOT go for a lewd photo shoot with her sister. How had such a picture of her ended up in a magazine? Was this some kind of joke?

Despite her shock, Luna was uncomfortably aware of the wet spot underneath her as she squirmed in her seat. She reluctantly turned the page. Her breath hitched as she saw what was on the next page. The image was of her was giving her sister extremely enthusiastic cunnilings. They both wore faces of intense pleasure, her sister moaning loudly as she stared up at the ceiling.

Luna’s hoof had traveled south without her even realizing it. She pleasured herself to the lewd scene, breathing through her mouth huskily as she experienced the pleasure. There was just something so hot about the idea. She and her sister’s faces were filled with such pleasure, and seeing her muzzle buried in her own sister’s body felt so wrong yet so right at the same time. She could almost hear her sister moan in her head as she studied her face. She rubbed herself frantically, approaching her peak much sooner than she anticipated.

“Oh, Celestia!” She moaned, her body forced over the edge as she leaned forward onto the desk, her hoof still grinding against her clit. She plastered her face onto the desk, not a care in the world about anything except for her clenching marehood.

As her pleasure died down, she picked her face up off the desk. She was suddenly aware of the sweat on her forehead. Her mane was attracted to her sweat, matting it down against her face. She blushed crimson, suddenly realizing what she’d done. She had been so aroused that she didn’t even have time to think about the fact that she was masturbating to her sister.

She frantically gathered up the magazines and shoved them into the bag. She then shoved them under the comforter on her bed and got back into the shower, shocked and disgusted with herself.

||||||||||||||||||||||||||||||||||||||||||||||||

“Luna?” Celestia called, knocking on her bedroom door.

There was no answer.

“Luna, are you awake?” She called again.

When there was no response, she reluctantly opened the door to her sister’s chambers and stepped inside. Her eyes were immediately drawn to her sister’s bed, which lay empty. Her ears twitched as the sounds of running water reached her ears.

She’s in the shower. She realized.

She decided to wait for her. She walked over to her little sister’s bed and laid down on it, pausing in surprise as she felt something under the blanket. She used her magic to pull the blanket back and pulled out a plastic bag. Curious, she removed the contents from the bag and was shocked to find several issues of Celestia’s Secret.

She was aware of such magazines, of course, but she hardly thought her sister would be in possession of them.

Hmmm…I haven’t read this one yet. She thought to herself as she opened the magazine and started reading. Beyond the visual depictions of her with other ponies were short “clopfictions” as they had come to be known over the years. This one involved her and the pony that she commissioned to create the Canterlot Gardens and was rather heavy in the romance department.

She heard the water being turned off but she paid it no mind, continuing to read the story in front of her. The sound of hooves skidding to a halt on the tile reached her ears, and she looked up to find a very flustered looking Princess Luna.

“S-sister?!” She exclaimed in surprise.

“Oh, hello, Luna.” She said warmly. “How are you this evening?”

“I-I can explain!” Luna exclaimed frantically, running over to take possession of the offending material.

“No need.” She said, holding up a hoof. “I know very well how hard it is to deal with these urges by yourself.”

“B-but this is pornography of thee!” Luna protested, shocked that her sister was taking it so well.

“Well, of course.” Celestia said calmly.

“Why…how could thou do this?!” Luna exclaimed. “Thou art a Princess! How could thou have had sex with so many ponies while allowing thyself to be photographed?!”

Celestia sighed, closing the magazine that lie between her front hooves.

“I see you haven’t seen the issues involving you and me then.” She said in realization.

“You and me?” Luna asked nervously, gulping in fear. She was done for.

“I’m not surprised if you just started reading these.” She said. “The first Princest edition came out not long after you returned.”

“P-Princest?!” Luna exclaimed, horrified.

“Yes.” Celestia said, sighing. “It’s a combination of the words Incest and Princess.”

“Princest…” Luna said softly under her breath.

“If you do not wish to see those then I can give you the edition numbers so you can avoid them.” Celestia said.

“W-we have already seen one…” Luna admitted, blushing profusely.

“Oh?” Celestia said in surprise. “Then you must realize that I wasn’t actually in any of these pictures. New technologies have allowed ponies to create many things, not all of which are exactly appropriate.”

“W-we are sorry, sister.” Luna said, shame in her voice. “T’was not we that procured the material. We fear that the librarian was playing a prank on us.”

“Why do you say that?” Celestia asked.

“Because she brought us pornography of thee!” Luna exclaimed, exasperated.

“There wasn’t much else she could do.” Celestia said calmly. “No other porn has been produced since your banishment.”

“What?” Luna asked, a look of surprise on her face.

Celestia sighed.

“A long time ago, I foolishly tried to ban pornography. I thought that love rather than lust should prevail, and I attempted to encourage ponies to write romance novels instead. I was surprised to find out that so many romance novels that came out were about me and another mare or stallion. I couldn’t very well ban such things seeing as I had encouraged the writing of romance novels in the first place. By the time I legalized pornography again, ponies had gotten so used to me being the focus of romance novels that it was only natural that pornography featuring me made it into the mainstream. Eventually that’s all that ponies produced. It’s not something that I enjoy or approve of, but this was brought about by my foolish attempt at banning pornography in the first place. I figure this is my just reward for my foolishness.”

There was a long moment of silence between them as Luna tried to process her sister’s words.

“S-so there is no other pornography that doesn’t involve thee?” She asked.

“Sadly, no.” Celestia lamented. “I destroyed all the existing pornography when I banned it.”

“W-we cannot believe this!” Luna exclaimed angrily. “How art we to get off then?!”

“You mean you’ve never masturbated to these magazines?” Celestia asked. “Then why do you have them?”

“We just got them!” Luna exclaimed.

“And they didn’t turn you on, even a little?” Celestia asked, smirking.

“W-we…” Luna stammered, stepping backward.

Celestia got off the bed and sauntered over to her. She stopped when they were a mere head apart and looked down at her sister provocatively.

“You know, I wouldn’t be opposed to trying out some of the things in those magazines with you if you want.” Celestia said, a warm smile gracing her face.

“T-thou cannot be serious, sister!” Luna exclaimed. “Fantasy is one thing, but this - ”

“You’re not the only one who has needs…” She said, leaning forward and whispering in her ear. “…And you’re not the only one that has a collection of Celestia’s Secret magazines hidden in her bedroom.”

“R-really?!” Luna asked incredulously.

Celestia laughed.

“There’s not any other porn out there, so yes, I have clopped to the idea of you and me on more than one occasion.” She admitted candidly.

Luna stood there frozen and blinked a few times, her mouth hanging open as she tried to process her sister’s words.

“What do you say, sister?” Celestia said mischievously. “Do you want to clop to the fantasies in these magazines or do you want to turn fantasy into reality?”

Luna sputtered, taking a step back, her front hoof still raised in anticipation of further retreat.

“T-’tis madness!” She stammered, a look of horror on her face. “We art sisters!”

“Yes, we are.” Celestia said, smirking. “And sisters should always help each other, should they not?”

“B-but…” Luna stammered, putting her hoof down once again as her brain started to catch up to the situation. “It does not bother thee that we art sisters…?”

“You are very attractive, Luna.” She said, a gentle smile making its way onto her face. “And you obviously have needs. All I’m saying is that I would be happy to help you.”

“Hast thou been with a mare before?” Luna asked curiously.

“Yes.” Celestia said.

Luna looked surprised hearing this, but her features eventually softened.

“W-we have not.” Luna admitted, averting her gaze.

“I would be happy to teach you.” Celestia offered.

A blush spread across Luna’s face as she considered her sister’s proposal and she turned away in shame.

“‘Tis wrong to have such desires.” She muttered under her breath. “We can not…”

“What’s wrong, being with another mare or being with your sister?” Celestia asked, putting a hoof on her shoulder in concern.

“Both!” Luna exclaimed, pulling away from her.

Celestia lowered her hoof, her eyes softening.

“Feelings are never wrong, Luna.” She said. “Are you not the least bit attracted to me?”

Luna spared a look at her sister’s body, starting at her hooves and moving her gaze upward. As she got up to her sister’s face and she gave her a gentle smile, Luna turned away, her blush intensifying.

“T-thou art not…unattractive, sister…” She admitted. “But we do not know…”

Celestia stepped forward, wrapping a hoof around her younger sister in a warm embrace.

“I love you, Luna...” She said softly. “I don’t want to push you into anything, but if you do want some relief, I won’t judge you. Everypony has needs like these, and it’s always nicer if you have somepony to help you.”

Luna looked up at her older sister as she pulled away.

“W-what does it…taste like?” She asked curiously.

The heat in her cheeks had subsided a bit by then, but it came back with a vengeance as she asked such a lewd question.

Celestia was a bit surprised by her sister’s question, but she smiled gently.

“It varies from mare to mare.” She said. “But so long as it’s clean, the taste isn’t unpleasant.”

She could tell that Luna was lost in thought as she considered what to do next. Celestia decided this was a good opportunity to tease her sister.

“Why?” She asked, smirking as she started to turn around slowly. “Do you want a taste?”

“NO, NO!” Luna exclaimed, flailing her hooves frantically.

Celestia laughed, turning around and rubbing her sister on the head teasingly. Realizing it was a joke, Luna started laughing too.

“Thou art mean, sister!” She said.

“What can I say?” Celestia asked, laughing. “I’m still your sister. I have to tease you every once in a while.”

Luna’s smile faded slowly as she started thinking again.

“Sister, we do not wish to be selfish, but…” She said, trailing off. “Never mind…”

Celestia knew exactly what she was going to ask.

“It’s okay, Luna.” She said gently. “Although it’s only polite to return the favor, I won’t hold you to it.”

“A-art thou sure?” Luna asked in surprise.

“I don’t want you to do something you don’t enjoy.” Celestia said, smiling gently. “Nopony has ever found my taste to be…unpleasant, but if you do then I won’t expect you to go through with it.”

All of her barriers were breaking down. Yes, having sex with another mare (let alone her sister!) was normally thought of as wrong, but she did have needs that weren’t being satisfied. Her sister was even willing to simply give her pleasure with no commitment on her part. There was just one other thing that was bothering her.

“I-If we ask thee to stop, thou will?” She asked nervously.

“Of course, Luna.” Celestia said.

Luna sighed audibly, lowering her had in defeat.

“A-alright, sister…” She said.

“Get up on the bed, Luna.” She said, gesturing with her hoof.

Luna walked over to her bed slowly. She couldn’t believe she was actually doing this with her sister. As she laid down on her back, she looked down between her legs at her sister nervously. Celestia had crawled onto the bed with her and had taken a position between the lunar mare’s legs. Their eyes locked for a moment before Celestia cast her gaze downward toward her sister’s marehood.

Luna’s marehood was perfect. Puffy blue lips surrounded a small sliver of pink flesh. Celestia moved her muzzle down towards her most private of parts. Luna tensed in preparation of the sensation, but was surprised when she felt her sister kiss between her thighs. The situation was undeniably erotic, and she couldn’t help but spread her back legs a bit as she experienced the new sensation.

Celestia peppered her lower region with kisses, carefully avoiding her marehood. Her goal was for her sister to anticipate and eventually want her touch. A few gentle moans escaped the blue mare as she acclimated to the sensations.

Deciding it was time, Celestia finally kissed her marehood directly. Luna’s breath hitched in her throat as she felt her sister’s muzzle against her marehood. She was extremely gentle, giving her flower light kisses before starting to lick along the outer lips of her marehood.

“Ah!” Luna exclaimed, the sensations getting to be too much for her.

Celestia went back to kissing around the outside of her marehood, making the lunar mare whimper in eagerness.

Celestia couldn’t help but smile as she heard the desperate whimpers from her sister. She decided that now was the time to put her out of her misery. She put her muzzle directly against her sister’s marehood before opening her mouth and letting her tongue slip inside of her.

Luna had never had another mare’s tongue inside of her before, and she couldn’t help but moan in pleasure from the new sensation. Celestia continued unabated, paying special attention to her clit as she focused on her tongue work.

Luna tensed and gritted her teeth, drawing in a sharp breath at the overwhelming sensation. Celestia sensed this immediately and backed off, knowing that she would push her sister over the edge if she continued. Luna’s body relaxed as the pleasurable sensations lessened and she suddenly felt very heavy on the mattress.

“Oh, sister…” She said softly.

Celestia continued her efforts, brining her sister close to the edge before backing off again. As Luna started approaching her peak again, she couldn’t handle it anymore.

“Please, sister…” She begged.

Celestia knew exactly what she was asking and happily obliged, using all of her skills to push her sister over the edge.

As Luna got closer and closer to release, her sister didn’t let up at all, pushing her ever forward toward her breaking point.

Luna leaned her head back, pushing her upper body off the mattress and moaning loudly in release.

“Ooooooooooooooooooh!” She moaned, her entire body shaking in pleasure.

Her flower spasmed around her sister’s muzzle, gripping on it as if it were a stallionhood that her body desperately wanted to keep inside of her. Her orgasm lasted what seemed like forever, and she felt exhausted as it finally washed over her.

Celestia looked at her sister. She was panting heavily, her body completely collapsed on the bed. Her eyes were closed as she tried to catch her breath. Celestia pulled herself forward and rested her head against her little sister’s chest, listening to her heartbeat. It thudded rapidly in her chest. When she felt her sister squirm under her, she pushed herself up and forward, kissing her on the cheek.

“Did you enjoy that?” She asked, chuckling.

“’Tia…I…” Luna said.

“Shhhhhhhh…it’s okay.” She said softly. “Just rest.”

Luna’s eyes fluttered close and Celestia smiled down at her. She got off the bed as gently as she could before making her way to the door.

“Maybe tomorrow you’ll want to return the favor.” She said to herself thoughtfully.

With that she closed the door behind her, making her way down the hall, her sister’s fluid still covering her muzzle. If anypony asked, she’d just tell them it was cake frosting.
