Luna lay awake in her bed, unable to sleep. She tossed and turned, the covers mangling about her hooves and wrapping her up in their linen embrace. The princess of the night kicked out in an attempt to free herself, but to no avail.

She sighed, and struggled against the cocoon of blankets in which she was wrapped. “Oh, for goodness sake!” She gave another kick, but only succeeded in wrapping herself tighter in her blankets.

A long, drawn-out sigh escaped her lips, and she flopped onto her bed. “What are these feelings?” she wondered aloud. “Why do I feel this way about her?”

She shook her head, and pushed the invading thoughts to the back of her mind, before collapsing onto the bed, wrapped in her linen casket, with a heavy sigh.

“She wouldn’t understand anyway.”

The morning came, and Luna rose from her tangle of blankets, her mane as tangled as the blankets in which she was wrapped, and her eyes red and bloodshot from lack of sleep. She struggled to free herself, having surprisingly more success than last night, and heaved herself onto the edge of the bed.

She struggled onto her hooves, and tried to walk, but her exhausted legs gave out almost immediately, and she collapsed back onto the mattress with a soft thump.

She sighed, and forced herself to her hooves once more, trotting shakily out of her bedroom and into the dining room, where she found her sister waiting patiently for her.

“Dear, Luna, what is the matter? You’re usually the first one up for breakfast, and somehow, I am the one to best you. “What is on your mind, sister?”

Luna shook her head and trotted into the dining room, sliding her chair out and flopping into it tiredly. “It is nothing.” Luna assured her sister, but her tired eyes and slumped posture said otherwise to the ivory-coated mare.

“Rubbish. Luna, you have obviously not slept well, and as such, I insist that you tell me what is the matter. I want to help you.”

The ebony-coated princess glanced at her sister with her reddened eyes, and sighed. “It is nothing, sister. Now please, just leave me alone.”
Celestia sighed and returned to her meal, casting a worried glance over at Luna, who slumped in her chair, poking at a soggy bowl of cereal with her spoon.

After watching her sister poke her cereal with her spoon for the millionth time, Celestia decided that she had had enough. She got up from her seat, and whisked Luna’s bowl out from under her nose. “That is it.” she snapped. “I have had enough of this nonsense.”

Luna glanced up at her sister, an annoyed expression on her face. “What?” she sighed. “I told you, nothing’s wrong.”

Celestia shook her head. “That is rubbish, and you know it. You haven’t said a word since you got up, and I am worried. Your eyes are blood red, and that is not healthy.”

“I told you,” muttered Luna, getting up from her seat, “that nothing is wrong. What is so hard to understand?” The princess of the night stormed out of the room, her silver-shod hooves echoing on the marble floors.

Celestia put up a hoof to stop her, but decided against it. Her sister would grow out of this, she was sure of it.

Luna stormed angrily through the halls, the sound of her hooves booming in the long corridor. “Why does she always do that?” she fumed. “I’m fine. I just…” The princess of the night sighed and slumped against a wall, hiding her head in her hooves.

“I just can’t tell her how I feel…”

She looked up as the heard somepony else approach her in the hall, the tell-tale sign of metal on stone telling her that it was either her sister. or one of the guards. Her suspicions were confirmed when the horned shadow that was thrown onto the wall by the burning sconces flared its wings.

“Luna?”

The night princess sighed and got up, torn between walking towards, or away from her sister.

“Luna?”

She sighed and turned towards the sound of her sister’s voice, walking through the hallway until she could see her around the corner. When the sun princess caught sight of her, she galloped towards her and threw her forelegs around her neck.

Luna returned the hug and sighed, sobbing gently into her sister’s flowing rainbow mane.

“Oh, sister, I’m so sorry. I shouldn’t have stormed out like that.”

Celestia laughed in that musical way of hers, and kissed her cheek. “Do not worry, sister. It is OK.”

Luna looked up at her with tear-filled eyes. “R-really? You’re not mad at me?”

Celestia laughed and stroked her mane. “I could never be mad at you, Luna. It wasn’t your fault. I pushed too hard. But I am worried about you.”

Luna sighed. “I know sister. I’m just not ready to tell yet. You understand, don’t you?”

Celestia nodded and smiled. “I understand, sister. When you’re ready to tell me, just come and find me, OK?” She brushed her hoof against Luna’s cheek and smiled.

The feel of Celestia’s hoof against her cheek made Luna blush, and her nether regions began to burn, throbbing gently. Luna let out a small whimper, but managed to suppress it.

“Sister? What’s the matter?”

“I-it’s nothing sister,” Luna stuttered, the burning in her loins returning. Her back hooves skittered nervously, and she could feel herself getting wetter.

Her heart raced, and she was almost sure that Celestia could hear it. ‘Please, sister,’ she thought desperately. ‘Just leave, or I might not be able to hold back…’

Celestia smiled at her sister, and nodded. “Well, if you’re sure. I shall return to my chambers, and if you need anything, don’t hesitate to call me, OK?”

Luna nodded, and Celestia turned to go. As she reached the corner, she stopped, and looked back at her sister with her kind, amethyst-coloured eyes. “Oh, Luna?”

“Y-yes?”

“Make sure that you don’t get any on the carpet.”

Luna burst through the door to her chamber, and threw herself onto her bed. “Oh, sweet Celestia! What is this feeling? I’m burning up!”
Her hooves shook as she spread her hind legs, and rubbed furiously at her swollen, dripping marehood. Pleasure surged through her, and she let out a passionate moan. “More!”

Her pace increased, and her pussy became wetter and wetter with each furious stroke. “Mmm! I can’t take it anymore!” Her mind went blank with pleasure, and she pushed her hoof into her pussy, desperately wanting more.

Her lust burned brighter, and her womb started to itch. “Oh my…”

She rubbed her clit faster and pushed her hoof deeper inside her, desperately trying to reach the itch that had started in her womb. “More! I need more!”

The night princess stroked her pussy, rubbing it against the wooden posts of her bed in an attempt to soothe her burning loins. “I can’t take this anymore! But what can I do? I can’t just ask her!”

She rubbed her pussy faster, feeling her impending orgasm building up within her. “Oh, sweet Celestia! It’s coming!”

Her pants increased in frequency and her heart raced inside her chest. Rubbing her pussy faster, she felt herself becoming hornier, and the orgasm inside her building until she felt as though she was going to burst.

“I- ahh!” Sweet juices squirted out of Luna’s pussy, drenching the sheets upon which she lay and filling the whole room with the odour of her potent princess sex fluids.

Luna collapsed back onto the bed and her heart thundered in her chest. “Oh my…”

A knock sounded on her door, and the night princess bolted up from her bed, certain that whoever was on the other side of the door could easily smell her pheromones through the walls.

“Y-yes?” she called. “What is it?”

“Sister?” called the pony on the other side of the door.

Luna got shakily to her feet, struggling to stand on her legs, which had turned to jelly after her heated experience. “Yes? What is it Celestia?”

“Can I come in?”

Luna sighed. “Y-yes. You can come in, Sister.”

The door opened, and Celestia trotted into the room, her nostrils flaring as she caught the scent which lingered in the air. A devious smile formed on her lips, and she looked at her sister.

“Oh, Luna…” she said. “What have you been doing in here?”

The night princess blushed. “Whatever do you mean, dear sister?” she asked nervously.

Celestia laughed. “Oh, come off it, sister. I can smell your fluids like a hound.” She trotted across the floor to Luna’s bed, her golden-shod hooves echoing on the stone. The smell intensified the closer she got to Luna’s bed, and her nostrils flared once more.

“Oh? It appears that you forgot to clean up after yourself.”

A deep crimson blush appeared on Luna’s cheeks, and she burned with embarrassment. “Sister! What in Equestria are you saying?”

Celestia chuckled. “Nothing. I merely stated an observation. Perhaps you should have thought twice before letting me in, hmm?” The sun princess took her sister’s chin in her hoof and brought it up to make her sister face her.

“Sister! You’re embarrassing me!”

“Am I?” Celestia smiled and glanced back at her sister, who was blushing furiously.

“Oh, stop!”

“Oh, fine. What, if I may ask, was the… ‘inspiration’ for your little ‘adventure’?”

“Sister!”

“All right. I’ll stop.” Celestia laughed and smiled at her little sister.

“Thank you. Now, is there something you wanted, sister?” asked Luna, her face still burning with embarrassment.

“Yes, actually. You don’t think I came in here just to disturb your… moment, did you?”

“You knew?” asked Luna.

“Of course, sister. I could smell it from outside the door.”

“Oh…”

“Did you enjoy yourself, sister?” asked the ivory coated mare. “I trust that you plan to take care of your… mess?”

“Sister! Of course, I will!”

Celestia laughed and nuzzled Luna’s cheek. “Do not worry, dear sister. I am only teasing.”

“I should hope so! I may be younger than you, but I am still thousands of years old, and as such, am perfectly capable of dealing with my own… mess.”

“I know you are, sister. I would never assume anything less of you.”

Luna sighed and swished her starry tail across her dripping nether regions, wafting the scent of her sex right into Celestia’s face.

The ivory mare fought the urge to moan as the smell hit her; even she, the princess of the sun, couldn’t deny that she was getting turned on.
“Sister…”

Luna smiled mischievously. “Yes? Smell something you like?”

Celestia snapped herself from her stupor and shook her head vehemently, her rainbow coloured, ethereal mane flying about her shoulders, lashing the air like a whip. “No! Nothing!”

The sun princess’s heart thudded in her chest, as Luna pressed herself against her, looking into her sister’s eyes and forming a devious grin on her lips.

“Really? Is that so?”

“Of course! How on earth do you expect me to be attracted to another mare, and to my own sister at that!”

Luna smirked and pressed herself harder against her sister’s chest. As Luna nuzzled her, the sun princess was sure that she could no doubt feel her heart beating like crazy inside her chest.

“Very well, sister. I have no reason to be believe that you are lying.” This, of course was a huge lie; Luna knew exactly what was happening, and she was enjoying teasing her sister with her advances.

The sun princess shuffled uncomfortably against her sister, not because she wasn’t attracted to her, but because she didn’t want her to feel the sexual heat that her body was radiating.

As Luna pressed herself against her sister, Celestia gulped loudly, and her heart thundered in her ears. She wasn’t sure how much longer she could hold back, but she knew she had to.

The feelings that had been welling up inside her threatened to break free, but Celestia forced them down inside her, and stammered “Luna, I have duties I must see to. Please, clean up after yourself before you leave.”

The princess of the sun hurried out of the room, and, taking the door handle in her magical grasp, she pulled it shut behind her with a bang.

When she reached the hallway, she let out the pent-up breath that she had been holding in since Luna began her advances, and leaned against the wall, her knees suddenly going weak from exhaustion. Her mind whirled, and she pushed the thoughts deep into the back of her mind.

How on earth was she going to explain this?

Author's Note

So this was a pretty spicy one. It looks like somepony is starting to have certain feelings for her sister. We shall see how this plays out in the next chapter.
