The moon was high in the sky, casting its soft light through an open window and filling a rather large room with a soft glow. In the middle of the circular room was an extremely large bed. Upon the bed lay a sleeping form, one that seemed far too small for such a piece of furniture.
The large golden doors opened and then shut themselves once more, as a small blue figure entered the bedroom, a pony with blue wings, with an unnaturally long horn upon her head. She walked to the bed and looked down at the sleeping figure. Her sister was pink, and rather lanky, with a mat of mint-like hair that swayed and twirled even in sleep.
Luna nudged her older sister, trying to wake her up without frightening her. Celestia stirred a little before looking at Luna, “Is it time to raise the sun already?” Celestia asked sleepily.
“Not quite,” Luna said in her soft sweet voice.
“Then what is it?” Celestia asked, the concern was clear in her voice. She pulling her blanket away and getting to her feat.
“Calm down, nothing’s wrong, it’s just that… I was reading a book on biology and something came up… Something that caught my interest… Something I wanted to experiment with… And I couldn’t wait till morning… Sorry.” Luna finished her statement with an apologetic smile.
“No worries my dearest sister,” Celestia said, wiping the sleep out of her eyes, “and what is this thing you’ve decided to experiment with?”
“The method in which ponies multiply their numbers in order to sustain their population, also known as…”
“SEX?!?!” Celestia finished the sentence, now shocked into full wakeness.
“Exactly,” Luna said in a matter-of-factly tone, “And I want to try it out… With you,” she said, hopping onto the bed, causing Celestia to edge away slightly, “Not that I want us to have kids, apparently that only happens if it is between a male and a female anyway. I just want to see how it feels, apparently it’s really good.”
“I’m sure it is,” Celestia said nervously, almost falling off the bed now.
“The book also told me that sex should only be conducted by 2 ponies who truly love each other. And… Well… The only pony in the world who fits that description is you, Tia.”
At this, Celestia did fall off the bed. Luna ran over and helped her up. Celestia sat in the middle of the bed and thought about it, “Well alright,” she said. It did seem a little odd to her, having sex with her younger sister, but if it stopped Luna from deciding that she loved some helpless pony before molesting them, then she would grin and bear it.
Luna smiled and made Celestia lie on her back. Luna sat on her sister’s chest, then thrusted. Their crotches collided but nothing else happened, no out of the ordinary feelings, no sense of joy, just the feeling of something pressing against their pelvis. Luna looked down at her crotch then back at Celestia, the look of confusion was clear on her face. “Am I doing something wrong?”
Celestia chuckled at this, “Your book didn’t say anything about mare on mare did it?” she said in a joking tone.
Luna just shook her head, “Only that it was possible.” Luna knew what was missing here, but she tried to think of a way around that.
“Here, let me try.” Celestia got up and pushed her sister onto her back. This time Celestia gently pressed her right hoof against Luna’s chest, slowly lowering it until it reached Luna’s crotch. She began rubbing her hoof in a circular motion and Luna’s eyes widened. “How does it feel?” she asked curiously.
“It feels… Wow.” Luna had never felt anything like this before. She couldn’t explain what it was, or why she liked it, but something inside her flared up. “Let me show you,” she said, twisted around until her face was near Celestia’s crotch while Celestia could still feel Luna’s own. Luna kissed Celestia’s crotch, sticking her tongue deep inside her. Celestia’s eyes dilated, she pulled her chin up and let out a deep moan. Alarmed Luna pulled her tongue out, “Oh no, did I hurt you?” she felt a little bad about that, especially since something in the back of her mind wanted Celestia to do it again.
“No-no, I really liked that,” Celestia looked down at her sister and smiled. For a moment Celestia had felt something she wanted to feel again more than anything. She couldn’t even wait for Luna to respond and pressed her crotch against Luna’s face, causing her to grunt in protest. “Do it Luna, do it now and don’t stop!” Celestia moaned again when Luna stuck her tongue back inside her. Celestia lowered her head and began licking Luna’s crotch rapidly.
Luna wondered what had gotten her sister into such a frenzy. As she poked her longue in and out of her, wriggling her tongue around and sliding it across the walls, Celestia’s body began to quiver in excitement, her wings had fully extended and she began to pant and moan loudly.
Celestia dipped her tongue inside Luna’s pussy, while continuing to rub her crotch with Celestia’s right hoof. Luna let out a moan, this excited Celestia’s already excited body and she started to slide her pelvis across Luna’s snout.
This made it quite difficult for Luna to lick her sister’s pussy, but Celestia seemed to like doing it quite a lot. She let out a deep moan every time she slid her crotch, a sound which Luna had figured by now meant it was enjoyable and for what ever reason, Luna was enjoying having her sisters crotch slid across her face, while it wasn’t physically a good feeling, it was making her body shake with excitement, and her mind fray, a powerful, good emotion boiled up inside her as if Celestia was having sex with her mind.
The feeling boiling up inside Celestia’s body was overwhelming her. She could no longer control herself. She pushed her crotch hard against Luna’s face. So hard in fact that Luna’s snout entered Celestia’s pussy. The sudden penetration made Celestia cry out.
Luna felt her mouth being locked shut, and the wall of Celestia’s pussy, pushing from all sides. She tried to cry out for Celestia to stop but all that came out was a muffled groan. Celestia took her sister’s grunting and struggling as a sign that she liked it. She continued to thrust her pelvis; all other thought processes were drowned by the barrage of feelings. Luna’s snout was sucked in and out of Celestia’s pussy, and she struggled to free herself, pushing Celestia’s pelvis with both hooves, but to no avail. While it was physically uncomfortable, Luna’s mind was overtaken by the emotions that threatened to break her apart.
Luna enjoyed every moment of being bombarded with feelings, both physical and mental and there was nothing she could do to stop them being forced into her anyway. She stopped struggling and let Celestia take over, the feelings getting noticeably stronger.
The feelings inside Celestia began to build up until she felt like she was about to erupt, and it wasn’t long before she did. A hot white liquid spilled out of her and ran down Luna’s neck, shortly afterwards a similar liquid was ejected from Luna’s body.
Celestia had run out of energy, and lay limp on top of her sister. Luna used her magic to free her snout. Raising Celestia’s pelvis into the air, before letting it drop back down.
Celestia turned and spoke, her breathing still heavy, “We should do that again some time.”
“Yes, but next time, I’ll go on-top.”
Author's note: I attempted to use avoid the use of the words "Pleasure" and "Arousal" both to represent Luna and Celestia's knowledge of the word, and as an exercise in trying to portray those senses in a way that doesn't involve blatantly stating their presence.
