A Fall Festival Fun Time

“Isn’t this fun, sister?” Luna spoke in her canterlot voice as she turned to face Celestia.

The two royal mares sat on two comy massage chairs, side by side. Princess Luna wriggled about in her chair to help the mechanical device hit exactly where she needed it to. She looked to be enjoying herself, a look of bliss on her dark blue face. Celestia, on the other hoof, was having a less enjoyable time. The two were partaking in the annual Canterlot Fall Celebration, a yearly festival featuring lots of fun games, tasty foods, and exciting events to get ponies excited about transitioning to the next season.

“I would not call this my definition of fun, no.” Celestia replied with a touch of annoyance in her voice. She was much too big for the chair, the mechanic knobs underneath the smooth leather only massaging her lower back and butt. “And please, remember to use your indoor voice.” she said with a wink.

The open night air flooded into the warm tent as the station owner bashfully trotted up to the princesses.

“I-I’m sorry to disturb you, my princesses, but I must remind you that your session is up. Unless you don’t want it to be! T-That’s fine! You may also pay for another 20 minutes if you would like to, but of course I won’t--”

The mare was cut off by Celestia raising a dismissive hoof.

“Please, My Little Pony, this is your business. We are simply patrons. I insist you treat us no different than any other paying customer.” Celestia said, giving the shy store owner a warm smile. She nodded happily. Luna gave a frown and appeared to want to say something, but bit her lip and forced a smile much less warm than her sister’s.

“Thank you for your patronage then, my princesses. Please have a fun and safe night!” The store mare said, giving them a polite nod as the two exited the tent. Luna paused, staring back longingly at the comfortable chairs as they were switched off, but hurried out to meet her sister on the street.

“Sorry Luna, but we shouldn’t use the power we hold just to get what we want from our citizens. That’s why we’re here, remember?” Celestia said, ending her sentence with a chuckle.

As upset as Luna was about her current lack of massage chair, she had to admit that Celestia was right. The two were attempting to make more public appearances now that ponies were beginning to see them as tabloid features. This was Celestia’s, and the other princesses as well, attempt to make their country see them as ponies rather than gods.

“You are right as always, my sister.” Luna said once again in her canterlot voice. Celestia gave her sister a stern glare. Luna rolled her eyes and looked away before muttering out a “You are always right.” in a much lower tone of voice. So quiet, in fact, one might even think she hadn’t wanted Celestia to hear her.

“Thank you. We’ll get through this night together, Luna.” Celestia promised, knowing that this was all a bit much for her younger sister. Princess Luna had some social problems, not used to appearing before ponies in public spaces that weren’t press meetings or important parties filled with Canterlot elites.

“Shall we move along to our next activity?” Celestia asked as the two began to trot down the street. Luna smiled and nodded in response, practicing a quiet personality.

The stone traced streets of Canterlot were packed with stalls and booths promoting, selling, or sharing food, games, activites, crafts, and just about everything else you could hope to find. Celsestia stopped at a game booth, causing Luna to bump into her. The mare running the station tried to suppress a giggle. Luna bit her lip to hold herself back.

The sign above the booth proclaimed “APPLE BOBBING!!” in bright, messily painted orange letters on the dark brown wood. They glowed a bright neon as the light from the street light lanterns reflected off of them. The mare running the game snapped back to her stage persona.

“Step right up, bob for an apple and win the apple! Yes, that’s right, free food if you can catch it in your mouth! Princesses, glad you stopped by! Would either of you like to play?” She said, flashing a toothy smile. Celestia nodded and smiled back.

“It’s just Celestia and Luna. We don’t want to be treated any differently from another pony on the street.” Celestia insisted. “But yes, I wouldn’t mind giving it a try.”

“Then plop your head down there, Miss Celestia! Don’t boil my apples if you miss your shot, though!” She winked at the sun goddess. Luna rolled her eyes.

“Oh, trust me, I do not plan on it.” Celestia prodded back. She dunked her head into the water, her mane flowing out and almost covering the entire surface of the barrel. She swung her head around underwater, desperately looking for an apple. Finally, her teeth sunk into a delicious red fruit.

Standing next to her, The Princess of the Moon smirked. Her sister, bent over next to her, tail flicking back and forth? Luna could barely contain a laugh. Hey, if Celestia was having so much fun tonight, she should get to have some too! She slowly looked left, right, back and forth, just to make sure no one was looking before she swiftly grabbed Celestia’s tail. She leaned in quickly, puffing a warm breath against her sister’s marehood lips. They were nice and warm, radiating heat. She slowly dragged her tongue up the center of Celestia’s pussy, quickly pulling back to pretend nothing had happened.

Celestia jerked her head up and out of the water, an apple between her teeth and her soggy mane covering most of her face. That was a good thing, since it hid her burning blush. Water was flung everywhere, making the service mare look like she was running a dunk tank. Luna stepped back, covering her muzzle to muffle a laugh as she stared at her sister’s dripping wet face. She was sure that was no longer the only part of Celestia that was moist.

“Great job, Celestia!” The mare running her apple bobbing booth said, smiling even though she was drenched. Celestia turned to Luna with a scowl.

“Thank you. PRINCESS LUNA, A WORD?” Celestia spoke in a VERY canterlot voice. Luna raised an eyebrow and nodded, following her sister as she stormed away. The store mare looked on in confusion, staring at the apple the sun princess had left behind.

Celestia trotted all the way down the street, ignoring ponies and games and cameras as Luna followed behind her. She entered the public bathroom, nodding for Luna to follow her in. Celestia’s horn flared, locking the door behind them. This was rather impolite for any other mare who needed to use a bathroom.

Celestia made sure there were no other ponies with them in the large bathroom, letting out a flustered and angry sigh. She brushed her long and sparkling mane out of her face, still rather wet. It was quiet enough to hear a pin drop in the bathroom. Luna tensed up as she studied her sister’s angry face.

The first sound to break the silence between the two princesses was the sound of a droplet of liquids hitting the floor. Celestia blushed and slowly relaxed her back legs. The droplet had not come from her soaking wet mane, but from her soaking wet marehood. Luna smirked a wide, toothy grin. Celestia continued her silent glare, her cheeks glowing red.

“What exactly was your intention with the action that you performed?” Celestia said through grit teeth. Luna looked away uncomfortably.

“Just trying to have some fun tonight, since you appear to be having so much yourself.” Luna said with a little giggle.

“Yes, yes. But in PUBLIC? Around our citizens? What if one of them had seen you?” Celestia questioned, refusing to yield her icy stare.

Luna chuckled in response.

“They could have, but they did not, fair sister. You’re rather flustered now, are you not? It would be even more inappropriate if someone captured a picture of that mess you are making.” Luna commented as a slow trail of marejuice dripped down Celestia’s thigh.

Celestia finally broke off her eery stare, looking back at the puddle she was leaving on the floor.

“Yes. I assume it would. Which is why you will help me remedy this issue.” Celestia ordered. A wide smile spread her face as her horn flared, and this time not to unlock the door. Luna gasped as she felt herself caught in a magical field and dragged over to her sister, who shoved her face into the puddle and happily plopped down on top of her. The heavy weight was enough to hold her to the floor with no chance of squirming out.

The scent of her sister’s juices flooded her nostrils as she held her mouth shut tight. She swallowed hard, as it had began to water. A whine escaped her lips as she slowly opened them, and let the taste flood her mouth. She dragged her tongue through the puddle. Luna’s body shuddered and began to rise in temperature, a blush filling her own cheeks as well as her sister’s.

“Clean the floor up, Luna, for being so disrespectful to both the festival, the community, and your sister. Clean it with your tongue, since you had no problem using it for other actions one might deem inappropriate for its use.” Celestia said in a strong, dominant tone. She slowly moved her forehooves to Luna’s flanks, and lifted her tail up. Just as she suspected, Luna was dripping wet as well. Too bad Celestia didn’t plan on helping her out just yet.

Luna muffled something angrily against the floor, Celestia’s body squishing her down. She had no choice but to continue the lap up her sister’s heavenly juices. Her own pussy burned with need as her tail was pulled away and it was exposed. She dripped onto the floor below her butt. The scent of hot, sticky marejuice flooded the room, and Celestia’s nostrils.

“Now you are the one making a mess, my dear sister!” Celestia teased with a loud laugh as she squeezed the blue mare’s flanks, rubbing a hoof over her cutiemark. “One might even assume that you are enjoying yourself!”

Luna could do nothing in response but spread her legs on instinct, huffing and panting as she slurped and lapped at the floor, cleaning it of Celestia’s uncomfortably delicious juices. But why was she so turned on? She heard Celestia’s horn flare, and squealed like a pig that just had it’s ass slapped. Celestia’s magic wrapped around her sister’s clit, trapping it in a pleasurably tight embrace and began to gently press the nub with her magic, peppering an equivalent of gentle kisses over Luna’s clit.

Princess Luna began to moan loudly, muffled by the floor and trapped under her sister. She tried to close her legs, but Celestia’s magic spread them and held them in place with what appeared to be magical bondage. Not that it really mattered, nothing Luna could do could stop her sister’s magic as it began to press harder. Luna was REALLY dripping now. She screamed again.

Celestia pulled her hoof back from where she had just spanked her sister. She rubbed the slowly reddening spot.
“Luna! You are making a mess and you must stop right now or face further punishment!” Celestia said with a toothy smirk, settling in comfortably to trap her sister. “You are getting too much pleasure just from cleaning my juices.” She said, pretending that she wasn’t pleasuring her sister’s dripping marehood with her magic.

Luna could only attempt to kick and squirm. The floor was completely cleaned of Celestia’s juices, Luna’s tongue now hanging out of her mouth for a different and much more pleasurable reason. Celestia brought her other hoof up, bringing it back down hard on her sister’s other flank. Luna let out a loud moan of pleasure, her pussy briefly gushing juices in response to the spank. Celestia giggled.

“Oh goodness, my sister. No matter what I do, it appears that you may end up cumming from receiving your punishment… that wouldn’t be much of a punishment at all, would it?” Celestia said, her horn releasing her clit. It moved to tease and spread Luna’s puffy ponut, still keeping her legs spread. Luna’s clit winked desperately, the princess having been just on the edge of an orgasm. Celestia stood up, releasing Luna… only for her magic to spin her around.

Luna gasped for fresh air as soon as she was lifted from the ground.

“CELESTIA! LET ME G--” Luna tried to demand, before her face was pressed into her own juices as Celestia sat down on top of her once more. Celestia continued to toy with her sister’s ponut.

“I can only assume you were going to say, ‘Let me clean up my mess like a good citizen.’” Celestia said, barely able to suppress a giggle at the end.

Luna gave labored breaths as she tried not to breath in her own scent. Her warm juices covered her muzzle. It was only a matter of time before she was forced to open her mouth and begin to slurp and lap at her own liquids. She gave low moans as Celestia spread her ponut this way and that, her magic slipping just inside at some times.

“Luna! You are a naughtier mare than you let on. So wet from just licking up your own mess? I know it couldn’t be from having your tailhole toyed with, that's just too naughty, even for you…” Celestia prodded knowingly, the two having spent much time together alone in the castle, more than enough to get to know what brought Luna pleasure in bed.

With a rather complicated maneuver, Celestia flipped Luna face up on the ground, and settled down on top of her. This time, she was using Luna’s face as a chair. Celestia’s burning, dribbling marehood lips rested right over Luna’s muzzle. Celestia’s clit winked. Luna groaned but began slurping at her sister’s pussy.

“My d-dear sibling! Already knowing what I desire without a command? Maybe you are growing smarter…” Celestia said through muffled moans, squirming and grinding down on Luna’s face. She pressed her plot harder and harder against the source of her pleasure, Luna’s tongue.

Luna’s tongue work was that of an expert’s. She slurped and lapped, wriggling her tongue like a snake deep within Celestia’s marehood walls. She flicked this way and that, sliding in odd angles or repeatedly lapping at places within those moist walls that got particularly loud moans from her sister.

The younger princess could soon tell that Celestia was getting closer and closer to orgasm by the moment- and unfortunately, Celestia could too. Celestia leaned forward, beginning to furiously rub a hoof over Luna’s marehood, focusing on her clit. Luna tried to cross her legs as she moaned loudly, the pleasure running through her, but Celestia kept them firmly spread with her magic.

Luna instead pressed upward, beginning to suckle and slurp at Princess Celesta’s clit. The two sisters assaulted each other until finally, they achieved orgasm in unison. Celesta’s body went limp as she shivered and groaned happily, all stress and anger from the night leaving her body with her juices as she rubbed Luna through her orgasm. Luna shook and shuddered in pleasure as she squirted, trying not to drown in Celesta’s warm juices as they covered her face.

For awhile, the two layed there in their shared mess.

After a good moment, Celestia released Luna from her bondage and stepped off of her face, legs shuddering. She grabbed a paper towel in her magic and wiped up the spilled juices as Luna caught her bearings. The two sisters stood there in the bathroom, panting softly as they recovered from the experience.

“W-well, my sister, I trust you have learned your lesson?” Celestia asked with half lidded eyes and a dirty smile, giving a little giggle as she leaned against the wall. Luna, still recovering from the orgasm that had been much longer and drawn out than Celestia’s, was slow to respond.

“Y-yes, my sister. You are the boss, and it was n-not right of me to embarass you in front of our subj-” Luna caught herself, frowned, shook her head, and then smiled at Celestia. After a brief pause, she finished, “...Our fellow citizens of Canterlot.”

Celestia gave one of her classic warm and proud smiles and stood up straighter, seemingly ready to face the day now that she had had a moment to truly relax and get everything out and settled with her sister. The two exchanged a long, loving glance as Luna stepped toward the door to meet Celestia.

“Good then, sister. I may be rough at times, or my methods may seem unorthodox, but trust in knowing that I only ever want what is best for both myself, my fellow citizens, and the mare I hold closest to my heart- which of course, would be you, my sister.” Celestia lectured to her younger sister. Luna rolled her eyes and followed it up with a quick smile.

“I understand, Celestia.” Luna nodded at the sun princess as the two stepped out back into her night, their manes glittering as they trotted along the path back toward the festival to rejoin their fellow ponies in the autumn themed events.

Luna seemed much happier that night, and even the moon seemed to shine a little brighter. The two royal sisters treated each other with much more respect as the night continued, and by the end of the festival, they were in sync once again.

Later that night, in Celestia’s private quarters, Celestia had just settled in to dreamland. Luna grinned as she entered her sister’s room quietly. Her horn lit as she entered Celestia’s dreams, concentrating to remain quiet.

It was time for some payback.~
