Sweet Dreams, Fluttershy

A silent, pleasant night had fallen onto the realm of Equestria, the moon was full and high in the sky, casting its calming light over the ponies's realm, and there was no cloud to hide the magnificence of the starry sky from sight.
(Perfection...) thought Princess Luna as she looked at the sky from her balcony. She only wore a see-through blue nighty with silver stars and her signature moon crest which showed her beautiful body, her private parts barely covered by a black bra and panties with dark purple frills all around gently hugging her plump curves. Her starry mane gently moved with the calm, slightly chill wind which brought some peace of mind in that otherwise hot summer night and her dark blue horn shimmered gently as she was ready to commence one of her favourite night duties: being the Dream Guardian, which meant checking everyone's dreams and help them face their worst nightmares. She scanned the city with her glowing horn, being happy that no one seemed to suffer from nightmares, when suddenly her attention was caught by something: an immense feeling of lust. It was so big that it started to affect herself as well, she bit her lower lip and rubbed her luscious thighs together as the sexual desire being transmitted to her was overpowering her usual composure. She shook her head and tried to pinpoint the location of the lust wave, using all her willpower to try and not give up to what her body needed. She finally found the cause of her sudden sexual need: in her house, FlutterShy the Pegasus aka the Element of Kindness was moaning in her bed as she dreamt of being surrounded by incredibly sexy mares and that they were all dominating her in extremely kinky ways, kissing, groping and rubbing her body sensually and causing the shy pony to grope her huge breasts and finger her wet pussy in her sleep, until she orgasmed which caused her to shook awake, thus breaking the connection with Luna, who fall on her knees, panting and with a wide wet stain on her panties. After a while, Luna regained her composure and got up, spreading her magnificent wings as she knew what to do.

FlutterShy groaned and got off of bed, heading for the kitchen to pour herself a glass of milk. Out of all her friends, she was by far the sexiest. Her breasts were big and plump, flopping freely as she walked since due to the heat of the night she was sleeping fully naked, and her butt and thighs were as sexy as her boobs, even though she was so embarrassed by her huge rear and pretty much her entire overlysexual body. She huffed as she walked near a mirror and stopped in front of it to look at herself, with a discontent sigh.
(This body of mine only attracts thirsty males... When all I'd like would be for some nice girl to notice me...) she huffed, before heading towards the fridge (Ugh... If my friends, or anyone at all, ever finds out that I like females, it would be too embarrassing...) she whined, pouring the milk in a glass and downing it in a gulp, when she heard the door knock.
“Huh? Who could be at this time?” she asked, going to the door and realizing she was naked only when she had already opened the door. With a shy squeak, she covered herself the best she could even before she noticed who was at the door and her cheek lit up with a deep red of embarrassement.
“FlutterShy...” said Luna, folding her arms below her ample chest, which could rival FlutterShy's in terms of size.
“P-Princess Luna?! W-what are y-you doing h-here?” asked the shy pegasus who kinda hilariously failed to properly cover herself.
“Uh... I was checking everyone's dreams tonight... When I stumbled on your dream...” said Luna, rubbing her arm as she was kind of embarrased as well. FlutterShy'e eyes widened and she slid back in her house.
“Y-You saw?!!” she asked, gasping.
“I have...” replied Luna “And I am here to help you with it...” she said walking to her and gently a hand on FlutterShy's shoulder.
“You... You w-want to h-help me... W-with it?” she asked, blushing even harder and shivering a bit.
“Don't worry, I won't tell anyone... It will be our little secret...” she said smiling reassuringly, enough for FlutterShy to get up on her feet.
“R-really?” asked the shy pony, still covering herself.
“It's a promise from the Princess of the Night, dear child. It won't be broken by anything” said Luna with a pompous tone and helding out her hand. FlutterShy gulped a bit but nodded and grabbed it, then the alicorn used a spell to teleport both of them away.

They reappeared somewhere else, in a secret room Luna had herself built long ago. FlutterShy gasped as it was huge. She couldn't see the end of it and it was completely filled by what they had to be the biggest pillows in the realm, a seemingly infinite sea of red, blue and violet pillows.
“W-what is this p-place?” she asked as she struggled to keep her balance on the pillows, who were immensely soft to the point that she was actually kinda sinking on the pillow she was on.
“I had this room built for me when I returned to be Princess Luna. I wanted this calm, vast space of comfiness all for myself. Not even Celestia knows about it.” explained the alicorn smiling “I trust you won't tell anyone about this, right?” she then asked to the pegasus, who nodded.
“O-of course... B-but... N-now what d-do we d-do?” asked FlutterShy, since she had zero sexual experiences. Luna smiled and licked her own lips as she got closer to the blushing mare, swaying her hips as she walked to her and raised her chin with her index.
“You are indescribably cute and pure... I get to taste such a sweet innocence today... Don't worry, my pretty... Just let me do all the work... All I want you to do is enjoy it...” she said smirking while sealing her plump soft lips onto FlutterShy's, who widened her eyes and blushed even more. Luna wrapped her arms around the pegasus's slender waist and pulled her closer, their beautiful breasts mashed against each other as they kissed. Fluttershy made the cutest whimper as she hugged Luna's waist and slowly started to melt her resistance as they shared that moment in complete intimacy. As the kiss went on, FlutterShy started to getting more relaxed and even used some tongue as they made out, slowly Luna leaned back until she flopped on the immense pillow with the pegasus topping her and being lost in the sweet kiss. Soon FlutterShy pulled away panting and staring in Luna's gorgeous eyes, still seeming a bit resistant, but Luna smirked and dragged her closer.
“You are the most adorable thing, you know? And, in here, you can let go of any mental restraints...” she whispered in her ear, hearing that the pegasus's resistance crumbled definitely and she seemed ready and eager to have her desires satisfied.
(Maybe I can finally let go of those too... She seems the perfect mating partner...) thought Luna, smiling and caressing Fluttershy's mane.

“So, what shall we start to do?” asked the alicorn.
“Mmm... I say some fondling...” proposed FlutterShy. Luna nodded smiling and gently groped FlutterShy's big breasts, making her moan.
“Sorry, too rough?” asked Luna, not wanting to hurt her.
“I'm... I'm fine...” cooed FlutterShy, who also would grope Luna's tits, blushing “Geez, Your Majesty... Your boobs are so big and soft... Kinda like these pillows...” stated the pegasus, with such a kid-like tone that made Luna giggle.
“Now now, dearie, yours are just as big as mine... Heck, only my sister has bigger boobs... And please, in here call me Luna...” she said, fiddling FlutterShy's puffy nipples, making her whine a bit before imitating the princess and rubbing Luna's nipples with her fingers. As she did, she saw that Luna lactated so she stopped.
“Y-you're lactating?!” asked the pegasus.
“It's my magic's reflux, it causes me to lactate even though I'm not pregnant... Go ahead... You can do whatever you want with me...” Luna explained, still massaging the pegasus's sensitive nipples. FlutterShy nodded and, unbelivably for her, took both nipples in her mouth and started sucking while thoroughly massaging the princess's huge tits, which stimulated the production of more milk and also some moans from the ruler of Equestria. Soon the pegasus found herself addicted to the sweet taste of her princess's warm milk and couldn't stop drinking it, sucking more inside her craving mouth and massaging Luna's boobs a bit harder to get out as much as she could. Luna moaned a bit but nevertheless allowed FlutterShy to do whatever she wanted, letting the pegasus explore her body as much as she wanted. Soon though. Luna shifted her position, now having her face between FlutterShy's abundant breasts while the winged mare still sucked hers.
“M-Mnf?” asked FlutterShy.
“My turn” said Luna, taking both of FlutterShy's nipples in her mouth and imitating her, sucking and groping her boobs while murmuring a bit.
(MNF! W-wait! T-there's n-no milk in t-there!) FlutterShy moaned in her mind since her mouth was occupied by boobs.
(So what? It still feels good to do so...) replied Luna since she could read minds (Besides...) she added, chuckling and making her horn shine, as it did FlutterShy's juggs got filled with milk too.
“M-MNFF?!” asked the pegasus, moaning as her boobs felt heavier as they got filled by Luna's magic.
(Just a taste of things to come...) said Luna as she greedily sucked and groped FlutterShy's boobs, prompting the winged mare to do the same. The two continued for a while before they each had their fill and pulled away, panting. Luna licked her lips as milk kept trickling on her face.
“H-how w-was i-it?” asked FlutterShy, panting and moaning as she still squeezed Luna's boobs.
“Delicious... Like condensed milk... And mine?” asked Luna smiling.
“I-it was m-magic...” said FlutterShy, lowering her ears a bit “S-sorry, bad pun...” she whined but Luna giggled.
“I liked it” she said, reassuring the pegasus who made Luna get up.

“Y-your turn to do s-something” said the pegasus, wagging her tail.
“Hihihi, you're gonna like what I'll propose... Lay on the pillow with your face up” she said. FlutterShy nodded and did as her princess/lover requested her, laying down on the pillow and sinking into it a bit, then she waited for Luna to do something. The alicorn immediately got on top of her, but in the other sense: her shapely butt was in front of the pegasus's blushing face and Luna's head was pointed to her legs.
“Uh... W-what are y-you... UUNNPPHH?!” FlutterShy's sentence was silenced by Luna smothering her face with her rear, pressing her pussy against the mare's lips.
“I want you to lick my pussy... Eat me up while I eat you up...” said Luna with a lustful tone and rubbing her pussy on the blushing FlutterShy's face while she spreaded the pegasus's thick thighs and looked at her pussy, which looked so in need of Luna's tender care. She grinned and started to lick it, making the winged mare moan louder and also telling her what to do. FlutterShy shivered but soon started to imitate her again, licking Luna's already drenched pussy and tasting her delicious nectar while holding on to her bubble butt. Luna smirked and did the same, hugging her rear and massaging it while licking FlutterShy's pussy which also started leaking almost immediately. They kept the sensual 69 going for a while until they both came, gushing out their juices on each other's lips, then they pulled away panting and looking at each other, both blushing and smiling. Then Luna would lean on FlutterShy, letting her head rest between her boobies as she stared at her, giggling and wagging her tail.
“Uh... N-now what?” asked FlutterShy, getting a bit lost in Luna's beautiful eyes. 
“Now? Now it's time to play with magic...” said Luna smirking as her horn lit up in a dark blue light. As it shined on the two sexy mares, their curves started to grow. FlutterShy yelped as soon her tits were as big as fully blown beach baloons and they didn't seemed to stop there, the same was happening to her butt, as it greatly inflated to an almost absurd level. She whimpered then she watched her princess grew as bustier as her, with maybe some differences: FlutterShy's breasts were bigger than Luna while Luna's ass was bigger than FlutterShy's.
“G-Geez... Now I look even more obscene...” whimpered the pegasus, while Luna hugged her.
“Obscenely sexy, my delicious mare...” she said as she kissed the blushing pegasus once more while groping her insanely big and soft boobs. FlutterShy moaned as she felt Luna's fingers sink in her titflesh, and soon she groped her princess's ass, experiencing the same sinking feeling.
“L-Luna... Y-you're... S-so soft...” cooed the blushed mare as she fondled Luna's huge butt.
“Likewise, my dear...” said Luna, smiling and groping FlutterShy's massive boobs, mashing them onto hers and locking lips with her again, then one of her hands would go towards FlutterShy's pussy and fingered her, causing her to moan in the kiss before she did the same to Luna, who also moaned. The two incredibly horny mares rolled on the pillow, kissing groping and pleasing each other as their lust for each other grew, along with their bodies. In fact, the spell casted by Luna was acting again, this time making them more muscular. They murred, their lips and bodies almost glued together as they continued to make out, not realizing how buff they were getting until they had to pull away to breathe.
“W-what the? What happened to me?!” asked FlutterShy as she exhamined her body and Luna's: not only was she more muscular while also mantaining her usual feminine shape, she also became bigger! As in taller: she was now several feets bigger than before and Luna had underwent a similar change, becoming buffer and bigger than before while still keeping her feminine features.
“Huh... This was not planned... But I don't mind being this big” said Luna shrugging and smiling as she acknowledged how sexy and powerful she felt.

“Next, darling, let's use this” said Luna as she conjured up the most kinky sex toy FlutterShy had ever saw: it was a black double-headed dildo, only it was the size of a light pole!
“H-hoo boy...” cooed the pegasus, wagging her tail.
“Sit down, my gigantic beauty” said Luna giggling. FlutterShy nodded and flopped down, despite her massive size her butt still barely fitted one pillow, and spreaded her huge thighs, allowing Luna to gaze at her pussy.
“Perfect... Now, you probably have never been penetrated so this might hurt a bit...” said Luna, waving the dildo. FlutterShy gulped but nodded and breathed a bit to get ready. Luna got on her knees and held one end of the dildo in her hand and gently slid it inside the pegasus's pussy.
“IHN!” FlutterShy moaned cutely as her most private place got penetrated by the huge thing, which slid in up to its half. Luna then smirked and got seated just like FlutterShy and pushed the other half of the dildo inside her own pussy, moaning as she felt it go all the way inside. She would slide closer to FlutterShy to get it fully in and panted as she stopped.
“Mngh... F-feels good...” said Luna, moaning and biting her lip, then FlutterShy immediately started bucking her hips, making the dildo thrust inside her. Luna smiled and started to do the same, groaning as she felt the dildo move up and down inside her tight tunnel. The two massive mares started moving their hips in sync, their clits rubbed against each other due to how close they were and this only made them moan more. FlutterShy leaned on Luna once more, topping her and kissing her while moving her hips and moaning.
(Mngh... Like this, it's... Almost as if she's fucking me... God, that's so hot...) thought the Princess as she let FlutterShy be on top if that's what she wanted, hugging her closer and murring as their tongues coiled against each other in a wet sensual dance. FlutterShy pulled away again, a thin strand of drool connecting their mouths, and moaned loud as she moved faster, making Luna moan too as the pegasus pressed her huge tits onto hers and rubbed her nipples against hers.
“MMMGGGHHH... M-MY PRINCESS... I... I FEEL... S-SOMETHING...” moaned FlutterShy as she moved her shapely hips.
“M-ME T-TOO... I... I'M...” moaned Luna, squeezing one eye and arching her back as a sweet ecstasy passed through their brains and bodies.
“C-C-C-CUMMINGGGGGGG!!!!!!” they both yelled at the same time, their juices gushed out of their pussies and managed to made the dildo slip out and lay next to them as they panted and drooled after the orgasm. After they catched their breath, they looked at each other again and would kiss each other once more. As they did, however, they felt a raw surge of magic flowing inside their bodies, which grew exponentially one more time. They had became bigger than a house now, FlutterShy's breasts were now insanely big and squishy-looking, along with Luna's magnificent rear.
“W-wow... I'm... Starting to like this too... But don't you think it's dangerous for us or anyone else if we continue growing?” asked the pegasus.
“Nay... Whatever this side effect is, it's temporary... So I say, we take advantage of every moment we spend like this...” said Luna grinning as her horn lit again, enveloping herself in a reddish violet light which flowed down her massive body until it gathered on her crotch and would take a shape... A very obvious shape...

FlutterShy gasped as she stared at it: the biggest dick she had ever saw! It was as long as her actual arm and twice as thick! It was completed with a pair of huge wobbling balls drooping down from the base of it. Luna giggled and made it sway.
“Nifty trick, huh?” she asked giggling as she loved the face her mate was making.
“G-geez... Is there anything you can't do?” asked FlutterShy, imagining how a monster like that would feel.
“I guess not” said Luna shrugging and crawling on her again, being on top this time and poking the entrance of FlutterShy's pussy with it, making her murr.
“Now, ths isn't a real penis, it's just a magic construct. When it'll cum it won't impregnate you so you'll be all good even if I do...” she explained to FlutterShy.
“A-alright... P-please, put it in... I want to lose my v-virginity... W-with you...” the pegasus cooed, biting her lips as she barely could contain her own urges. Luna squeaked as she found her extremely cute and then started to slide in her temporary huge dick. The pegasus moaned loud as it was very big and the tip had some difficulty going inside, but eventually it did, breaking her hymen and causing a bit of blood to come out.
“There... I officially took your virginity... You're ok? Can I go deeper?” asked Luna.
“Y-YES! U-uhm, I mean... Yes, please... Put it all in...” moaned FlutterShy, gritting her teeth as she felt the huge tip going inside her tunnel. Luna nodded and would push it all inside with a quick thrust.
“F-FAAAAAHHH!!!” moaned the pegasus, feeling it filling her tunnel completely “I-IT'S SO B-BIG...I... I CAN'T C-CONTROL MY V-VOICE!!” she yelled, tearing up in bliss. Luna smiled and wrapped her arms around her neck and would start thrusting inside her, kissing her once more and pressing their boobs together once again. Luna fucked FlutterShy's cute pussy fast and hard, not being able to hold back at all due to how much she needed her, and basked in the turned on moans of her partner, who hugged her back and would move her hips in sync to Luna's thrusts. The more Luna thrusted, the bigger they'd get and actually they became so big that they managed to touch the ceiling of the supposedly endless room of comfyness. FlutterShy groaned in the kiss and kept moving along with Luna, getting closer and closer to cum. Luna pulled away from FlutterShy's lips, smirked and sucked both her nipples, making her moan and grit her teeth as she started to drool.
“AHN! AHN! T-TOO MUCH! I-IT'S TOO M-MUCH! I C-C-CAN'T... IIIIIIIIIHHHHHHHHHNNNNNNNN!!!!!” the pegasus moaned more as she came, but the alicorn wasn't done yet so she went harder on her mate, thrusting very fast inside her opussy and nibbling on her nipples, sucking on them and groping her massive breasts as hard as possible.
“HAH! HAH! HAH! HAH! S-SO ROUGH! MMMGGGHHH!!! M-MORE! MORE! AHN! P-PLEASE, DON'T STOP! D-DON'T STOOOOOOOOP!!!!!” FlutterShy moaned louder and louder, lactating and cumming yet again as Luna pleased her like never before. Luna gulped gallon after gallon of sweet, warm breast milk then she pulled away, grinned and finally came, releasing a huge tidal wave of sperm inside FlutterShy's womb.
“MMMMRRRRGGGGHHHH!!!!” she moaned as the cum actually made her belly grow larger, just as if she was pregnant, then they both had one massive surge of height and broke out of the room and out of Canterlot mountain, ending up bigger than anything else in the kingdom. Luna panted and pulled out her dick, which vanished, and would rub FlutterShy's enormous belly, purring and nuzzling with it with a satisfied smile.
“F-feeling better?” asked Luna to her mare partner.
“Hah... Hah... Y-yessss...” moaned the pegasus, back to being her usual bashful self.
“Good... I enjoyed it too...” cooed Luna as she went behind her and hugged her from behind, nuzzling with her cheek and giggling as the calm breeze of the night soothed the lust of the two gigantic sexy and satisfied ponies...


The End
