Chapters *BOOM *
The large door to Friendship Castle slammed behind Princess Twilight Sparkle as she nearly galloped through the main room.
“Oh, no! I didn’t mean to keep Celestia waiting this long!” The lilac alicorn worried to herself as she ran into one of the hallways. “Now she’s going to think I’m really irresponsible!” She kept running through the hallways until she finally arrived at her personal quarters, where she told her mentor would be waiting.
She opened the door in abject fear to what the white princess would think of her, only to be greeted by a sight that she could hardly comprehend; Princess Celestia holding her hoof at an angle above her and making a low whooshing sound as if she was acting out a fantasy, focusing on it as she moved slowly through the room. She moved and spun her hoof around slightly in relation to her body as she continued fantasizing, going for a while until she eventually bumped her hoof into wall.
“Awww...” She lamented, disappointed with her fantasy ending as she laid down and splayed her legs around her, seeming rather bored.
“C-Celestia?!” Twilight asked in utter confusion and shock.
The other alicorn pulled her head up and looked over at her. “Oh, hi, Twilight!” She responded gleefully as she got up and trotted over to her.
“W-w-what?!” The lilac pony yelled, still entirely bewildered.
“Is everything alright, Twilight?” Celestia asked as she crouched down slightly and looked at the other mare in concern.
“Y-you’re acting like a foal!” Twilight shouted in response, to which the white princess squinted in light confusion. “Y-you’re supposed to be professional! You’re the ruler of Equestria! You’re my mentor, and practically my mother!” She retorted.
The elder alicorn looked down for a few seconds, attempting to process what was said. She eventually looked up and replied, “Well, I think if I’m really acting like a foal, then it would be better if you were the mother...” She paused for a moment, adding a tad of drama before finishing, “Mommy.”
At that one comment, Twilight felt so much confusion and shock that her eyes rolled back up in her head and she passed out.
Princess Luna entered Friendship Castle, as a request from her sister to meet with Princess Twilight Sparkle, mostly to check up on her and talk about what has been happening with her recently. She roamed the halls, hearing no noise aside from her own hoofsteps until she heard some faint anguish from far down the hall she was in. She sped up her pace slightly and heard the voice to be familiar.
“Mommy, mommy, wake up!” She heard, the voice clearly being her sister’s, but the words confusing her. Nevertheless, she sped up to nearly a gallop pace as she approached the the open door to the room she remembered to be Twilight’s private quarters. ‘Please wake up, mommy!” The voice called again, sadness being discernable in it now, though the reason why her sister of all ponies would be crying about her mother still perplexed her.
When she arrived at the open door and saw the situation inside, she only got part of an answer. She saw her sister crying over the seemingly unconscious body of Twilight Sparkle and shaking her, trying to wake her up.
“’Tia?” Luna called, still concerned as to why her sister was acting so foalish.
Celestia looked up from the lilac alicorn and saw her sister at the door. “Lulu!” She cried, running over to the other mare and hugging her while she kept crying. “Help mommy! She won’t wake up!”
“Mommy?” The blue princess asked, somewhat confused as to what was happening.
“Yes, mommy Twilight! She won’t wake up!” The white pony cried out in anguish.
Luna looked at her sister in surprise as she understood what was happening, at least on some level. She pulled the other mare off of her carefully to allow her to move, then trotted over to the purple-maned princess. She held a hoof to her neck and lightly pressed, checking for a pulse.
When she felt Twilight’s heart beating normally, she pulled her hoof back and said, “Twilight is just uncon-” She cut herself off, realizing that if her sister was truly foal-minded right now, she probably wouldn’t understand that word. “Er, asleep,” She finished.
“Oh... well why isn’t she waking up?” Celestia asked, only a little relieved at the answer as she resumed hugging her sister.
“Ehm,” The night princess paused a moment to think of a good response, “She’s just really tired, ‘Tia. I don’t think thee should wake her, she probably needs the sleep.”
“Oh... okay,” The other mare replied in relief, her tears slowly coming to a stop.
Luna then kissed her sister on her cheek to comfort her, to which a light gasp of surprise was returned.
“What was that?” Celestia asked conspiratorially, vexed by the action.
“What was what?” The other princess asked, confused as to the change of tone.
“What you just did to me; what was that?” The white pony explained.
“Ah, that...” Luna started, amused by her sister’s confusion to seemingly everything, “We hath kissed thee.”
Her sister pulled back and looked at her in confusion, squinting her eyes and cocking her head slightly. “’We’?”
“Er, I ,” The blue alicorn corrected, before elaborating, “Mine language is slightly different to thine own.”
“Why?”
“Ehh...” The other mare paused to think. “We were... asleep ... for a very long time,” She fibbed to protect her sister’s newfound innocence.
“How long?” Celestia pressed, confused as to what she meant.
Luna inhaled deeply and contemplated the consequences of telling her the truth, answering, “A thousand years.”
The sun princess’ jaw dropped as she stared at her sister in shock. “A- wha- A thousand years!?” She yelled, aghast at the idea.
“Yes,” Her sister confirmed lamentingly, “It was because of another entity inside mineself whom also forces Us to reference Ourselves in plurality.”
“She sounds like such a meanie!” The white mare responded in affront.
“Yes... she truly is,” Luna said, resuming their hug once more.
Celestia kissed her sister on the cheek and gave into the hug, which lasted a few minutes where the sisters lightly cried into the other in lament of those dark times.
“Umm...” The solar princess eventually started, “About the kiss...”
“Hm?” Luna asked, pulling away slightly to look her sister in the eyes.
“I thought ponies were supposed to kiss each other on the lips...” The other mare replied, slightly retreating in embarrassment.
The blue alicorn blushed lightly from that, responding, “Well, we mustn’t have to... It’s just mostly for ponies that love each other very much...”
“Wouldn’t we love each other very much?” Celestia asked cautiously.
“Y-yes, I suppose, but-”
“But what?” The other princess interjected. “Lulu, can’t we kiss?” She pleaded, wearing an adorable set of puppy-dog eyes.
Luna took pause at that, closing her eyes and breathing deeply for a couple seconds. “I... I suppose we can...” She finally answered.
The white alicorn smiled brightly at the response, then stood still to allow her sister to kiss her. The sister in question smiled a bit at the other pony’s happiness before calming herself and slowly moving her head forward towards her sister’s. Their muzzles eventually met in a kiss, lightly pressing into each other to start with, but quickly became stronger as the sisters closed their eyes and shoved their mouths upon the other’s.
Celestia eventually started to press her tongue on her sister’s lips, which took little time to part and allow the princesses’ tongues to entangle and wrestle with each other in the joining of their muzzles. The passionate kissing pulled their senses to focus on only the other, so much so that they didn’t notice the purple and green dragon walking in.
When Spike walked in to check on Twilight after her meeting with Celestia and Luna, he instead found the two sister princesses making out messily with his quasi-sister laying on the ground nearby, unconscious. The shock and bewilderment showed on his face for several seconds as he took in the sight, but the emotions eventually got the better of his consciousness and he fell to the floor.
The resounding ‘thud’ when the dragon smacked against the floor was loud enough to pull the sisters to their senses of the outside world, making them halt their movements and stare at the other in surprise and fear. They then slowly pulled away from each other and looked over to where the sound came from. When they were standing on their own and saw the dragon, Luna sighed in light disappointment and frustration.
“Who is that, Lulu?” The solar princess asked, somewhat confused. “And why do they look so weird?”
“That is Spike,” The other mare replied calmly, “He is one of Twilight’s friends, and also is not a pony.”
“What?” Celestia asked, baffled by the prospect of a non-pony.
“He is a dragon, ‘Tia,” The blue alicorn responded, walking over to Spike and pressing a hoof against his neck. “He is also asleep, and the sound that hath disrupted us was his impact against the floor,” She added after a moment, pulling her hoof away and looking towards her sister.
The white pony paused a moment to understand what was said, and responded in a partially scared tone, “Why does everypony fall asleep around us?”
“The surprise Twilight and Spike felt when encountering you in your... abnormal state overwhelmed their minds and made them fall asleep, We imagine,” Luna calmly explained.
“A-abnormal?” The other alicorn said, now rather scared as to what was happening to her.
“Yes,” The blue mare replied, trying to comfort her sister, “When We stumbled across thee crying atop thine mother, We were also surprised as to thine abnormal state, but,” She sighed and paused for a second, attempting to find a good way to phrase the following statement, “Rest assured, We shall not judge thee for thine abnormality, nor shall we allow anypony else to act their judgement upon thee.”
“Oh,” Celestia sighed in relief, even if she didn’t fully understand what abnormality she was speaking of. “Thank you, Lulu,” She finished as she hugged her sister again.
“However...”
“Hm?” The white princess squeaked in light fear as she looked up at her sister’s face.
“We must meet with some ponies to discuss this abnormality and allow them to take care of you,” Luna started, pausing again in thought, “Because We are rather sure Twilight will take some time to get used to this state and is not the best pony to take care of somepony in this state,” She explained, making the foalish mare she was hugging shiver slightly in fear. “Do not worry, ‘Tia. We shall only tell few ponies, all of which We believe shall take your abnormality well.” She comforted.
“Oh, thanks Lulu,” Celestia replied with relief, even if a little confused by it all. “Um, who will you tell?” She asked.
“Oh, ah...” The blue alicorn stopped for a minute to think about who she thought fit to tell this about. “Fluttershy is quiet and calm, she’ll obviously work,” She reasoned. “Rarity is rather alright as well, Applejack We doubt would be able to spill such a secret, Rainbow Dash would likely laugh at this, so perhaps not... And Pinkie Pie,” She grimaced slightly, “While We doubt she would tell others, she make take some work to control.”
“We shall start with Fluttershy,” Luna finally said, pulling away from her sister. “Follow Us,” She added as she started to the door, her sister frantically following in her hoofsteps.
Princesses Celestia and Luna were walking down the halls of Friendship Castle to a side exit, as the front gates would be much too public for the sisters to leave without somepony noticing the white pony’s newfound foalishness. Said white pony was currently bouncing around with glee, whilst her sister was merely lost in thought.
When they approached the door, it began to open, causing the excited princess to stop and stare as two other ponies entered with pleasant smiles on their faces, but which turned to expressions of fear and obedience as they saw the royal sisters.
“O-oh, your highnesses!” The sapphire-coloured unicorn said frightfully as she bowed.
“Princesses,” The other unicorn, periwinkle in coat, said calmly, if a little confused by the royals’ behaviour.
The greetings snapped Luna out of her reverie, allowing her to notice the two ponies standing at the doorway. “Ah, Trixie Lulamoon and Starlight Glimmer, if We are not mistaken,” She started, failing to notice her sister’s bewildered, but excited expression. “Allow Us to greet thee, but-” She was cut off when her aforementioned sister’s excitement got the better of her, and she ran forward and hugged the two unicorns tightly, causing them to nearly go into shock and the indigo princess to put a hoof to her forehead and sigh in light irritation.
Celestia pulled back and looked at the unicorns, greeting them with mirth, “Hi guys!”
The cerulean and pink mares looked at the solar pony in utter bafflement until her sister interrupted, “Apologies for mine sister’s eagerness, she is currently unwell.”
“I... can tell...” Starlight replied flatly.
The white pony frowned after a couple seconds of silence between the four ponies, then shivered slightly.
“Is anything the matter, ‘Tia?” Luna said at her sister’s apparent fear.
“Um, yes,” The other alicorn started as she turned to face her sister. “Everything seems so scary when I’m this big, Lulu,” She explained, somewhat frightened.
“We suppose that makes sense,” The lunar princess responded as she put a hoof on her chin and closed her eyes in thought.
“Um, Trixie thinks there may be a way to fix that...” Trixie interrupted hesitantly, bringing both princesses to look at her in slight confusion. “Trixie knows there are size reduction spells...” She continued.
Celestia gasped, the smiled in happy anticipation as she looked to her sister. “What do you think, Lulu?”
“We believe that could work,” The indigo pony replied after a few more moments of thought.
The solar mare then bounced up and down in glee for a few seconds, cheering, “Yay! Yay! Yay!” The other ponies laughed from the sight before the alicorn settled down and eagerly asked, “Okay, so can somepony do the spell on me?”
The ponies chuckled again before Starlight stepped forward. “I got it,” She said and started to channel magic through her horn. The white mare stood still at looked at the unicorn in fear and anticipation as her horn charged up, the shot a beam of cyan energy at her. It felt odd when it hit her, like it was engulfing her and lightly pressing on her from all directions, and, soon enough, it started shrinking her.
The lavender unicorn continued to shrink Celestia down, only relenting when she was a bit larger than a foal. The alabaster mare then looked and moved around to get used to her new size for a minute, eventually stopping and running over to hug the unicorn.
“Thank you, Starly!” The princess beamed, clearly appreciative of her new size.
Starlight returned the embrace and amusedly said, “Of course, Celestia.”
The hug lasted for a few more moments before the white alicorn pulled back and looked at the other unicorn. “Trixie,” She addressed somewhat calmly.
“Yes?” Trixie responded, a little frightened from the change of tone.
Celestia looked at the sapphire mare in thought for a couple seconds, then asked, “Why do you refer to yourself in third-pony?”
The unicorn paused to think before replying somberly, “Trixie does that because she wanted to separate her stage and normal personas, but...” She sighed, recalling how mean to everypony she was as that stage persona, “They have become the same.”
“Oh...” The solar pony said as she saw the pain in the other mare’s face and walked over and hugged her.
“Thank you,” Trixie responded, returning the gesture. “I-”
“Mm, no,” The other pony interrupted and nuzzled her. “I think it’s cute.”
“O-oh,” The unicorn started, blushing from the compliment. “T-thanks, Celestia...” She added as she nuzzled back.
They continued hugging for several seconds before they broke apart and Celestia walked back over to her sister.
“Well then, Trixie and Starlight,” Luna began, “We thank thee for thine company, brief though it was, and what thou hath done for mine sister. But now,” She looked to her sister, “We must get going.”
The unicorn replied in affirmative, letting the sisters go around them and out the door with one last wave from Celestia.
The princesses then stepped onto the streets beside Friendship Castle and looked at each other.
“Now,” The indigo one started as she sat down, “Hop upon mine back.” The request was excitedly obliged by her sister, allowing her to stand up and extend her wings, then begin to flap them and force her off the ground. She then flapped her wings powerfully and rose into the sky quickly as she flew off to Fluttershy’s cottage while her sister screamed in thrill.
A loud squeal sounded through Fluttershy’s cottage as the water in a teapot started to boil.
“Coming!” Fluttershy shouted as she quickly entered the kitchen, as if trying to get the teapot’s attention. She picked the teapot up with a foreleg and placed it onto a tray beside the stove that already had a white cup on it, then shut the stove off. She next took the tray and put it on her back, using her winds to keep it steady as she began walking back out of the kitchen.
When she arrived at the coffee table in the main room, she carefully placed the tray on it and sat down on the couch next to it. She then took hold of the teapot again and poured some of its contents into the cup and set it back down, next tentatively grabbing the cup between her front hooves and bringing it up to her muzzle to lightly blow on it. After a moment, she took a sip, basking in the tranquility of the quiet, ambient wind and critter sounds in the pleasant midday light while she smelled the faint lavender of her tea.
Unfortunately, the serenity didn’t last long, as a resounding double knock came at her door, frightening the pegasus ans nearly making her drop her drink. She inhaled and exhaled deeply to calm herself before she sat her cup back on the table and hopped off the couch, then timidly trotted over to the front door. She closed her eyes for a moment to keep herself calm and reached a hoof forward to the door and opened it.
She next looked face-to-face with the princesses of the Sun and Moon, though something seemed a little off; notably the former being quite a bit smaller than usual and the latter having an expression of light fear and guilt on her face. The mares then stood there for a few seconds, just looking at each other before Luna spoke up.
“Hello, Fluttershy,” She said with the same tone as shown on her face.
“Um, hi...” The pegasus started before looking at the miniaturized Celestia in utter confusion. “Ummm...”
“Hi!” The solar princess chirped, waving at the primrose mare.
“H-hi,” Fluttershy lightly waved back then looked back at the other alicorn.
Luna closed her eyes and looked down for a couple seconds before beginning, “Ah, apologies, Fluttershy, for putting this upon thee so abruptly, but it appears Our sister is in need of a foalsitter.”
“W-wha?” The pink-maned pony stuttered, clearly bewildered by the suggestion.
“Our sister is not in her right mental state at the moment, so We shall need somepony to take care of her for the time being,” The lunar princess elaborated. “And, as to her current physical state, she felt unsettled by being larger than everypony, and so Starlight Glimmer agreed to shrink her to this size,” She added.
“Yeah, being bigger than mommy was scary...” Celestia added, looking frightenedly at Fluttershy.
The pegasus looked back at her, perplexed. “Mommy?” She asked, confused as to who that would be.
“Er, Twilight,” Luna corrected flatly.
“O-oh,” The yellow mare said, blushing mildly as she realized just how much a foal Celestia currently was. “W-well, I suppose I can foalsit her...”
“We shall not force this upon thee, Fluttershy,” The indigo alicorn replied in an attempt to relax the other mare, “Do not feel obligated to do this, We merely thought thou would be a good fit for this.”
“No, no, I can do it!” Fluttershy quickly responded, her voice louder than she meant which made her cover her muzzle with a hoof in a mix of shock and shame. “Um, I’m sorry,” She continued, back to her normal soft tone, “I can foalsit her, it’s just this is a bit, um, overwhelming.”
Luna nodded in understanding and said, “Of course. Thank thee for thine care and hospitality, Fluttershy.” She then looked to the side and saw her sister staring at one of the pegasus’s animals face to face. “Er, We suppose We haven’t told thee of the true extent Our sister is plagued,” She added as she looked back to the pink-maned pony with a slightly pained look on her face.
“Um, right...” The shy mare responded as she glanced towards Celestia before gasping and facing the other alicorn. “Oh, do you want some tea while you’re here? I already have some ready.”
The lunar princess smiled gently at the other pony and replied, “That sounds lovely.”
“Okay, give me a moment!” Fluttershy said as she ran back into the kitchen, leaving the indigo mare to trot over and sit down on the couch in the middle of the room, watching her sister slowly scamper about while looking around.
She turned to face the table when she heard a cup being placed on it, next finding her host to be pouring tea into a black cup beside the white one she saw there before. The pegasus continued filling the cup while staring intently at it as if she was trying to pull her focus from something else, likely being whatever was causing the slight blush on her face.
“Is anything the matter, Fluttershy?” Luna asked cautiously after the other mare set the teapot back down.
“Umm...” The shy pony started before sitting on the couch. “S-sorry, it’s just something stupid...” She said quietly, then glanced back to the night princess and saw a look of light concern and confusion on her face. “C-Celestia calling somepony her mommy sounds kind of... naughty...” She elaborated, nearly whispering as she looked away, blushing harder.
The blue alicorn chuckled lightly and blushed a little at that, then grabbed the black cup with her magic. “Mm, We suppose that makes sense,” She responded before moving the cup next to her muzzle and sniffed tentatively, smiling pleasantly from the scent. “We also suppose it is even worse given how Twilight is whom she calls such,” She added amusedly, then took a sip of her tea.
“R-right...” Fluttershy said before taking her own sip. “Um, do you know why she’s like this?” She asked after taking a moment to think.
“Not entirely,” Luna replied, then sighed and paused for a second. “However,” She continued, “We know Our sister has occasionally indulged herself with alcohol previously, to which the outcomes have been rather variable. None of them have really been as bad as this, though,” She said while glancing over to and waving a hoof at her sister, “So We need somepony to take care of her that We trust would not gossip about it.”
“Oh, okay,” The yellow pegasus responded, then went back to her drink. “But, wait,” She added after a couple seconds, “What about the castle staff? You don’t trust them?”
The lunar princess sighed deeply before replying, “Unfortunately, no. We know not much about them, and while they have sworn loyalty to Us, we doubt that they would be able to keep it entirely amongst themselves forever. And,” She continued, putting her cup back on the table, “It is easy to see why we have not chosen any other of our friends for this.”
“Of course,” Fluttershy responded and took a minute to think about her friends and how they clearly wouldn’t work for foalsitting princess Celestia. Rarity would probably be too busy, Pinkie too chaotic, Applejack not private enough, and Rainbow Dash would likely just make fun of her. She next opened her mouth to voice another question, but was cut off when she heard a high-pitched bawling unlike any of her animals.
The mares then looked at each other in confusion for a moment before turning around to find the solar princess sitting down and crying, a tinge of yellow coating one of her hind legs.
“Lulu!” The alicorn wailed, “Some weird stuff came out of me and made me wet!”
Luna then sighed and facehoofed while the other gained an amused blush. “Damn it.”
“Bye-bye, Lulu!” Celestia chirped while she waved, for more energetic than a few moments prior, as she wanted to give her sister the friendliest exit possible.
Luna cast an amused, yet happy glance back at her sister as she flapped her wings and took to the skies, flying off while the other alicorn watched with a smile befitting her foalish nature. Fluttershy, however, looked at the solar princess in a manner more akin to appreciation than worry, considering whether she preferred this version of Celestia over the previous one. She was snapped out of her stupor, though, when the alicorn looked back at her, fear plastered across her face.
“Are you sure I’m alright, Fluttershy?” The white mare asked, looking up at her foalsitter.
“Yes, I’m sure,” The pegasus comfortingly replied. “Wetting yourself is somewhat normal for somepony like you, but we will need to clean it.”
“Oh, okay...” The alicorn responded as she calmed down, then continued to look at the other pony when she noticed her staring. She bit her lip and hesitantly added, “So, are we going to do that, or...”
Fluttershy shook her head to clear her senses before blushing a little and replying, “Um, yes, sorry.” She next turned around and walked to the stairs and added, “Follow me.”
Celestia gingerly trotted over to the stairs and followed her foalsitter up them. “Did you wet yourself too?” The princess asked after a moment, watching the other mare as she froze.
“Um, n-no,” The shy pegasus stuttered.
“Really? You look wet in the same place I am,” The alabaster mare responded, looking at the liquid trickling down the inside of her foalsitter’s hind legs.
Fluttershy paused for a second before taking a front hoof and slowly moving it to her sex, then lightly pressed against it, finding it to be rather damp and leaky. Her face turned crimson red as she put her foreleg back in front of her and shamefully replied, “Um... I guess I did...” She started moving again, the other pony continuing to follow her, and added, “I suppose I’ll have to clean myself as well...”
“Oh no, I need to be really careful about this...” The pegasus though to herself as both ponies continued in silence.
When the pair made their way into the bathroom, the larger mare closed the door before walking up to the bathtub and turning the faucet on. The humidity and heat emanating from the water that then came out didn’t curtail the arousal the yellow pony was getting from being near the foal-ized solar princess, however.
While the prospect of being sexually intimate with Princess Celestia at all was very enticing, and having the alicorn be in complete submission to you was enough to drive most ponies up the wall with lust, what turned Fluttershy on the most was the fact that the pony was a foal. She didn’t know why, but the idea of having sex with a foal drove her mad with lust, well at least as mad as someone so quiet and peaceful as her could be. It may have had something to do with how innocent they are, their curiosity and spirit making it so easy to get your way with them, or maybe it was their size, being able to completely surround and dominate them, pressing yourself against their tiny sex and hearing their cute little moans as they writhed and batted their legs in an utterly adorable fashion that could never hope to be replicated by anypony larger or with more experience.
She was beyond thankful to have a new foal to take care of, but was also rather scared at the prospect of somepony finding about her fetish, goodness knows what would happen because of that, and especially because the effects of it all were increased a myriad-fold because the foal in question was Princess Celestia. Anypony finding out that she abused the alicorn’s mentally ineffectual state for her own sexual gratification would likely to try to crucify her, but at the same time, being able to do so to a Princess of Equestria, the Solar Goddess, she who’s name is said in vain, with little to no repercussions on her part was so unimaginably hot that she couldn’t not do it.
She was pulled out of her thoughts however when the aforementioned princess shouted at her. “Fluttershy!”
“Eep!” The timid pegasus jumped away from the other mare slightly in response, before looking at her while internally trying to calm herself from the scare and sexual high she just had. “Y-yes, Celestia?” She eventually stuttered out.
“Um, I think the bath’s ready,” Celestia replied, leading both mares to look over at the bathtub, which now looked to be nearly full.
“O-oh, right,” Fluttershy replied while she turned the faucet off. “Thank you,” She added, only looking back at the other pony though the corner of her eye as to now hide the massive scarlet blush covering her cheeks.
The miniaturized alicorn next reached up her forelegs to the rim of the bathtub, which was only slightly below her muzzle at the moment. The other mare watched her while she heaved her body up and over the rim, before falling into the water with a small splash. She got to her hooves, only her head being above the surface of the water, and looked expectantly at her caretaker, leading the pegasus to enter the tub in a similar, but slower manner to the foal.
The yellow mare grabbed one of the shampoo bottles and sprayed some of its contents onto a hoof, then put the bottle back in its place before approaching the other pony, who was now sitting down with her eyes closed and splashing the water around with her forehooves. She quickly stopped her movements when she felt a pair of hooves press against her side and start to rub some shampoo into her fur. She let the hooves slowly begin to roam around her body, going from her sides, across her back, up her front and neck, and took a while on her head, letting the kind mare bask in the utterly adorable ‘mrr’s that came from it.
After a while, Fluttershy lightly pressed the alicorn’s shoulders to get her to move back and lean against the wall behind her, then began working on her barrel which was mostly underwater. The little pony let out small gasps from the belly rub, which became more frequent and pleasant-sounding the further down she was rubbed, eventually turning into quiet moaning when her pussy started to get touched. The moans were like music to the larger mare’s ears, reminding her just why she loved foals much more than strictly appropriate, and the pleasure she heard behind them relinquished any doubts she had on the matter.
She continued pressing her hooves into Celestia’s sex, and grinned with glee while she heard the princess’s pleasured whimpers. Her grin became even bigger when she looked up to the white mare’s face and saw her utterly lost in the sexual sensations, occasionally biting her lip to stifle the coos involuntary flowing from her mouth. Once again, the mix of cuteness and sensuality completely addled the pegasus’s mind, drowning her perception of anything but the filly she found so lovely.
“Ah, Fl-Fluttersh-shyy...” The alicorn moaned, drawing the other pony’s attention to her words. “W-what are y-you doiiiing~?”
“Ah-, well,” She took a moment to think of an appropriate response, “I-I’m just washing your vagina...” She explained, trying to keep calm through easily the most arousing thing she has done in her life.
Celestia let loose a few more ragged pants before replying, “W-why does it feel like tha-aaat!?”
“U-um, well... it just does whenever your v-vagina gets rubbed,” Fluttershy responded while slowing her movements partially. “Um, do you want me to stop?” She asked, but was already pretty sure she knew the answer.
“N-no!” The white filly shouted. “It feels reeaahally gooooood!! D-don’t stop!!” She moaned as she was pushed closer to orgasm.
“Oh, okay,” The other pony replied quietly, hiding her thrill at the foal’s words and moans that was shown through her wide, yet determined eyes. She quickened her rubbing and begun focusing one of her hooves on the now-exposed clit of the alicorn while the other angled somewhat, pressing an edge slightly into the slit while it continued running along the labia.
Celestia’s moans turned into screams as she came, writhing in pleasure while her pussy sprayed its juices into the bathwater, the ministrations of her foalsitter not faltering in the slightest. The actions continued for a while, time losing its meaning for the mares from how enthralled they were by it. It did eventually end, however, the filly slowly coming down from her sexual high to pant from exhaustion while the other pony stopped her rubbing.
Fluttershy then let the alicorn rest while she looked on in disbelieving glee, wondering how she managed to end up in this situation. What celestial beings must have blessed her for her to receive personal responsibility for a foal-ized Princess Celestia she did not know, but was certainly never going to turn down such an offer.
Eventually the alicorn managed to regain enough of her breath to ask, “What... was that?”
The other mare blinked out of her stupour before meekly replying, “Um, that was an orgasm...”
“Okay...” The filly responded, not sounding like she fully understood what that meant. “So, are we done with the bath now?”
“Um,” Fluttershy started, “Yes. Let’s just get out and dry off.” She stood up and exited the bath, and, noticing the other mare to be still leaning against the wall, picked her up with her forehooves and laid her down on the tile floor. She next pulled the plug on the bath drain before picking up a towel off of one of the racks on the wall, and dried herself with it.
She hardly paid attentions to her actions while she stared at the exhausted Celestia, her forelegs folded above her barrel in an adorable manner while her hind legs and tail were splayed out, leaving her sex completely uncovered. When the pegasus managed to dry herself off, she tossed the towel into a laundry bin near the door and got another towel before approaching the filly, picking her up, and surrounding her with the towel.
The pegasus next rubbed all over the cocooned pony, drying her off and enjoying the cute giggling that came from her motions. She went on for somewhat longer than necessary to draw out the bliss, but eventually ended it, unwrapping the blanket from the foal and tossing it into the bin.
“Um, are you alright?” Fluttershy asked when she looked back at the alicorn.
“Really... tired...” Celestia replied, her eyelid drooping every few seconds from exhaustion.
“Oh, do you want me to bring you to bed?” The primrose pony responded, to which the other mare merely nodded. She picked up the filly and set her on her back before opening the door and heading out of the now rather humid room, then went into the bedroom and set her down on the bed. She quickly repositioned the foal to be laying on her back and tucked her under the covers, but upon seeing the purple and maroon light of dusk coming in through the windows, she got under the covers as well.
“Good night ‘Tia,” The pegasus said as she wrapped her forelegs around the filly, hugging her while she lovingly looked into the filly’s tired magenta eyes.
“Mhm,” The white pony responded before tilting her head down to press her face into her foalsitter’s soft barrel, weakly returning the hug while both ponies drifted off to sleep.
