Luna's Problem, Celestia's Solution

Luna worried herself into a troubled slumber. Her dreams were ravaged with a thought that she did not wish to confront. She despised it, yet it intrigued her. It played with her mind as a cat does with a ball of twine, dabbing at it but never actually grasping any sort of foothold. She tossed and turned in her bed. It was already difficult enough to sleep while her sister’s bright sunshine flooded through her window, but this dream made it nearly impossible. What was worse, she had no control over her own dreams. Her magical gift only extended to the dreams of other ponies.

She finally threw the covers off in disgust and began pacing around the room. The dirty thought continued assaulting the corners of her mind. She wanted it to leave, yet she was also interested in it. She hated it, but liked the idea at the same time. You whore! She screamed at herself, how dare you have these thoughts?! HOW DARE YOU?! Her moral compass was somewhat broken, as these thoughts continued plaguing her. She wanted something that nopony should ever want. It was disgusting to even think of something like this. She wanted to have sex with her sister.

Celestia, the kind, sweet, just, and amazing pony that co-ruled Equestria with Luna. In fact, it was Celestia’s sweet and friendly personality that had first drawn Luna in. She had noticed, over time, that her sister had one of the brightest and warmest smiles in all the land. She had also noticed the depth of her gaze, and wanted to drown herself in it.

But, she also noticed Celestia’s body. It was long and slender, with legs taller than anypony she knew. She also had a terrific looking backside, with a long flowing rainbow tail. She loved to watch her sister walk, because she carried herself so elegantly and regally. That being said, there were also times when her sister did the cutest things. She would gingerly wave a hoof at school foals as they passed by her coach. She would softly sip her tea at dinner time. She would prance about the palace when she thought nopony was looking.

Luna sighed dreamily at the thought of her sister, but then shook her head. SNAP OUT OF IT, DAMN IT! She yelled at herself, YOU GOOD FOR NOTHING, PIECE OF ABSOLUTE HORSESHIT! UGH!!!!!!!!!!!!!! She threw herself on her bed and began weeping openly. She cried until her bedsheets were soaked with her tears. She just wanted the torture to end. She wanted to experience peace and true happiness once again.

Then, suddenly, her door opened and Celestia peeked inside. “Luna? Are you okay, little sister?” Celestia asked. The nectar of her voice was sweet to Luna’s ear and she looked back and tried to cover up the small episode. “Oh, there’s no need to hide that from me, Luna,” Celestia said as she stepped over to where her sister lay, “if you’re sad about something, you know you can always talk to me about it.”

Luna looked up. The face she saw was one of true love and friendship. She felt even dirtier and more like a gutter slut than before. She began crying again. Celestia ran a hoof through Luna’s flowing mane and tried to soothe her. “Sh…” Celestia said softly, “it’s okay. Everything’s gonna be alright.”

“No!” Luna suddenly said loudly, “everything’s not gonna be alright! I’m a horrible pony!”

“What?” Celestia asked in shock, “Luna, how can you say that?! You’re a wonderful pony. Are you having nightmares about Nightmare Moon again?”

Luna shook her head, “no…it’s something much worse.”

“Well, you know you can always talk to me about it.”

Luna looked back at her sister. Celestia’s eyes glowed, and Luna thought her heart would melt. She examined her sister’s body, admiring every curve. Her wings, though furled, were still beautiful. She wanted her sister to use those magnificent feathers and pleasure her for hours on end. She became wet between her haunches at the thought and tried her best to look as if she wasn’t feeling any discomfort.

But Celestia picked up on it. “Luna, are you sure you’re alright?”

“I’ll be fine, Celestia,” Luna said, “I just need some time to myself, that’s all.”

Celestia noticed the strange way her sister’s face twisted up and the way her hooves quivered. She could put two and two together and figured that her sister was experiencing something that all mares experience. Celestia figured that Luna was deeply in heat, and she wanted her to leave so that she could masturbate.

“Luna, I know what’s going on,” she said.

Luna gave her a nervous look. “You…do?”

Celestia nodded, “I do, and it’s perfectly alright.”

“It is?”

“Certainly. Every mare goes through what you’re going through. I mean, we’ve both been alive for thousands of years. I’m fairly sure this isn’t your first time.”

“My first time for what?” Luna asked. She was completely confused. What on earth was her sister rambling on about? She certainly had never wanted to mate with her before. Yes, she had been through heat thousands of times, but it had never culminated in the dirty thoughts that she was thinking.

“Your first time…in heat,” Celestia said bluntly.

“Well, no, it’s not my first time,” Luna said, and then thought to herself, why am I discussing something so private with Celestia? Out loud, she said, “but it is my first time wanting to mate with the pony I want to mate with…”

Celestia took notice of Luna’s extremely guilty look. She hadn’t seen her sister look so guilty since before she turned into Nightmare Moon. “Luna…who do you want to mate with?” Luna looked back up at her big sister. She couldn’t take the stress anymore, and she blurted out without thinking: “YOU!”

Celestia backed up in surprise and dirty thoughts began coursing through her own mind. She had fantasized about being with her sister before, but she didn’t realize that the fantasies were reciprocating. It was almost as if the two sisters shared a brain length, joined by their mutual love, affection, and respect for each other. Now it seemed that mutual affection had turned into a hardcore lust.

Celestia slid over on the bed behind her sister, who sat weeping openly. Luna didn’t feel that her sister would ever show her love again. She had confessed to the biggest taboo in pony society. She wanted to sleep with her sister, and now her sister knew all about it. She turned and prepared for Celestia to strike her down or banish her back to the moon…but all that she felt were Celestia’s soft lips pressed against hers.

The kiss was a magical experience for both sisters. Celestia poured all of her love for Luna into that gesture, and Luna reflected it. They found themselves wrapping their forelegs around each other. Celestia ran her hoof up and down her sister’s back, and Luna did the same to her. They moaned into each other’s mouths, thoroughly reveling in the feeling.

When they broke apart for air, Luna cuddled into Celestia. “I didn’t think you would want…” She began before Celestia stopped her, “of course I want this. I’ve wanted you for a long time, Luna. I just didn’t know you felt the same way. Listen, I know you have to guard the dreams of Equestria tonight, and I do have some time right now, so…”

Luna put a hoof on her sister’s mouth and smiled. Celestia smiled back and blushed a bit, so Luna made her move. She kissed her sister once again, only this time the kiss was way deeper. She shoved her tongue into Celestia’s mouth, and swirled it around. Oh, no, you don’t, thought Celestia as she began battling Luna for dominance. She knew if she could gain control of the kiss, then the ensuing session could be done in her manner. If she didn’t dominate it, then Luna would never let her hear the end of it.

But, alas, Luna’s tongue was just too strong and she pushed Celestia onto her back. She wrapped her hooves around her older sister and went to work. She kissed her all around her neck and chest and moved steadily lower as Celestia’s moans grew louder. She didn’t have to say anything. Her vocal tones told the entire story. “Fuck me, dear sister,” they seemed to say.

Luna happily obliged as she finally made it to her sister’s back legs. She looked up and Celestia nodded. So she pulled them apart and finally got a view of something she had wanted for so long…her sister’s glistening vagina. It was magnificent, and Luna’s heart began to beat quicker just at the sight of it. She dove in and began to tenderly lick and tease Celestia. Her sister moaned with each brush of her tongue, as the princess of the night continued her work.

“Oh, yes, Luna. Oh, my dear sister,” Celestia said through her moans. She tried to spread her legs a little bit wider, allowing Luna more access. Luna took full advantage of it and plunged her tongue deep into Celestia’s nether regions. Her sister howled in sheer pleasure as Luna licked and sucked at her privates. It was the most exhilarating experience the white mare had ever experienced. She had never married, so she had never had the opportunity to mate. Now was as good a time as ever, and she wanted to lose her virginity to her sister.

So she suddenly bent back up and closed her legs. Luna went to shove her back down, but Celestia caught her and kissed her. Once she broke away, she whispered to Luna, “use your horn, my sweet sister.” She lay back and spread her legs once again. Luna smiled with devious intent and dove back in with her tongue. She wanted to make sure her sister was ready to receive her. Once she was done, she moved back up Celestia’s lithe body and silently commanded her to open her mouth. Celestia did so and Luna stuck her horn inside.

Celestia obliged to the intrusion and began sucking and licking on it. Luna moaned with each suck. What a lot of other ponies don’t know about unicorns and Alicorns is that their horns can be used in sexual acts, such as this one. It brought immense pleasure to the dark mare to have her sister sharing this with her. Her marehood tingled with excitement, and she couldn’t wait to lose her own virginity to Celestia.

But first, she wanted to make love to her sister. So she removed her horn and went back below Celestia’s metaphorical belt. She softly began pushing her horn inside Celestia. The Princess of the Day groaned as she felt her sister press. Deeper and deeper, the horn went until it struck a barrier. Both mares knew that, once that barrier was destroyed, Celestia’s virgin status would be revoked.

Luna couldn’t see Celestia’s face, but she knew she wanted it. So she plowed forward. Celestia howled in pain as her virginity was finally taken. Luna slowly bucked her head back and forth, trying to pleasure her sister as much as possible, but hating it because she knew she was causing her so much pain. Then, suddenly, Celestia’s howls turned to moans of agonizing pleasure. Luna picked up on that and bucked her head faster.

“Oh, yes, Luna!” Celestia moaned, “oh, please, more! Faster! Faster! Faster, you bitch!”

Celestia had never cursed at Luna before, but her mind was completely gone. She was caught up in the amazing feeling of her sister penetrating her most personal of orifices. Luna was turned on by Celestia’s dirty mouth and proceeded to plunge deeper and deeper. Her horn was coated in a thick layer of the liquid that poured out of her sister like a waterfall.

Back and forth and back and forth she went. The only problem with fucking her sister this way, was that she couldn’t use her hooves to pleasure her in other areas. She wanted to give her sister an amazing experience, and she felt that she was only doing 95% of what she should be. Her doubt ceased, though, as her sister let out a scream of pure delight and had a hard orgasm.

She shook with the pleasure and finally came down from her high. Luna crept over her body and kissed her. “I guess I did it correctly,” she said, smiling. Celestia chuckled through her panting, “yes, my sweet sister, you did do it correctly. But now I get to return the favor.” With those words, she snaked her way out from under her sister and went to her nether regions.

Once there, she made intense use of her own mouth. Luna moaned and cried out in pleasure as her sister’s smooth tongue tickled and teased and licked and caressed her pussy. “Oh, my darling Celestia! Oh, I love you! Oh, my wonderful sister! Oh!” She reveled in her sister’s warm and wet saliva dripping over her folds.

Then, Celestia stopped and used her magic to move her sister’s legs wider. Luna grunted with discomfort before she felt Celestia’s horn poke at her entrance, begging to be let inside. Luna nodded and braced herself for the painful beginning of her first time. Celestia gently moved her horn into position, then suddenly jabbed it inside Luna. Luna howled in pain as Celestia made rough love to her. Time after time, Celestia bucked as blood began to flow. But when that began, Celestia stopped and pulled out.

She quickly looked up to see tears forming in her sister’s eyes. “It’s not supposed to feel like that!” Luna complained. Celestia smiled in understanding and tenderly kissed her. “I’m so sorry, Luna. I forgot to properly lube up my horn. But now that I’ve taken your virginity, I can make you feel good in another way.”

With that, she sat up and moved her privates over Luna’s. She began brushing them together. Back and forth she went, holding her sister’s legs open with her hooves. Both mares began moaning loudly. Deeply pleasured sounds escaped from their vocal chords as both of their vaginas began pouring out liquid in response. Luna began bucking her hips, trying to match her sister’s rhythm. They both wanted this to last forever.

But ponies aren’t built to mate for that long, and so Celestia orgasmed again, her juices coating her sister’s lower half and spilling onto the bedsheets. Luna bent upwards and kissed her sister hard and screamed into her mouth as she came for the first time. Their bodies completely spent, they collapsed on each other and panted. “I never knew how exhausting sex was,” Luna said. “Did you enjoy it?” Celestia asked. “Of course, my beloved sister,” Luna responded as she looked up into her sister’s beautiful eyes. The two sisters kissed lovingly and cuddled into each other before falling into a deep sleep.
