“Mmmmm oh oh, Princess Luna!” Fluttershy mumbled as she rubbed her fingers against her clit, with her other hand massaging her right breast and moaned as she imagined her fantasy. She imagined the princess of the night feeling her from behind as Fluttershy took her shower and then she gasped as she came. She felt so ashamed of masturbating again, surely this was wrong and if Luna knew, it would be so embarrassing but then Fluttershy had a horrible thought. Wasn’t Princess Luna guardian of dreams? Then surely she knew! “No…No please no!” suddenly Fluttershy heard a loud knock on the door of her cottage and quickly pulled a towel around her “Just coming!” Flutttershy had a slender build except for her breasts which were almost as big as Celestia’s breasts. She reached the door, she was expecting Rarity for afternoon tea, she had to admit Rarity seemed a touch early but Fluttershy assumed she had lost track of time in the shower and besides Rarity had seen Fluttershy in a towel before now “Hello Rari….Princess!” as Fluttershy opened the door she saw Princess Luna standing on her doorstep “Princess! I can explain!”

“Now dear Fluttershy, I…” Princess Luna began but stopped short and then asked “Explain what? If you refer to your dreams about me…” she paused and smiled, so that’s what Celestia meant but how did her sister know? She decided to ask later but first “It’s nothing to worry about. For you see I too have had dreams about certain ponies and it’s perfectly natural”

“R….really? I had no idea…um would you like to come in? I’m expecting Rarity to join me soon for a cup of tea” Fluttershy said stepping to one side and letting the pony she fantasied about walk in. Fluttershy couldn’t help but cast a quick glance at Luna’s ass as she walked in and bit her lip. Her wings instantly became stiff “Oh no!”

“I saw that Flutterwhore” Luna said calmly, using her magic to close the door and then used her magic to pull the towel away. Revealing Fluttershy’s naked wet body for a moment and Luna smiled at the cute way Fluttershy covered herself “Oh relax, I too have dreamed of you….I want you for my harem….”

“A harem?!” Fluttershy gasped in shock and a little surprise “I…I…I’m no whore! I don’t want to be called Flutterwhore!” she paused and said shakily “I do however want to be in your harem….I want to feel your hands on my body…please”

“All my harem mares will have nicknames….Appleslut, Flutterwhore and Rainbow cum” Luna explained calmly “Applejack didn’t seem to mind her nickname…so why should you?” she reached forward and took hold of Fluttershy’s arms “Let me see”

“Oh…Okay” Fluttershy murmured, as Luna let go and Fluttershy let her arms fall to her sides “Does...this please you…ahhh!” Fluttershy suddenly felt Luna’s magic begin to play with her clit and she collapsed to her knees. Her hands went straight to the source of the pleasure and she moaned “Oh..yes…please….keep playing with me!”

“Do you accept you’re…um…pet name, Flutterwhore?” Luna asked stopping the magic but then said “You know Flutterwhore is an awful name…how about Flutterbunny?” Fluttershy nodded looking at Luna with Lust “Alright…let’s see you use that tongue. Lie down”

“Yes, Mistress” Fluttershy said as she lay on her back and waited. Luna stepped over and sat on Fluttershy’s face. Luna’s panties were already gone and Fluttershy began to lick “Mmmm!”

“Your…oh…very skilled at this…have you been licking somepony else’s pussy before mine?” Luna asked as she held Fluttershy head close to her dripping sex and felt Fluttershy nod her head “Oh…who? Was it Rainbow cum?” Fluttershy shook her head “Hmm then which pony?” she let Fluttershy pull away for a moment.

“It wasn’t a pony…It was Gilda….A griffin” Fluttershy said meekly as Luna moaned “She forced me…after I bumped into her…I had tried to run but she caught me here and…for two hours I licked her!” Luna could tell it was a painful memory “She then tied me down and used a strap on! She was so rough!”

Luna frowned, Fluttershy was the pony she had assumed was innocent, she expected to be trying to convince a pony with no experience to join but here Fluttershy admitted she wasn’t that pony and this made Luna feel sad for her “We can stop if you want to. I'll go take care of that foul griffin” Luna said trying to step off but Fluttershy grabbed her legs “Huh?”

“I dreamed of you before Gilda and I have since….please…don’t go!” Fluttershy said as she began to lick Luna’s clit and Luna arched her back in pleasure moaning, while also grabbing her breasts, her nipples getting hard but Fluttershy then added something that made Luna moan at the thought “I only ask that I…get to dominate you from time to time. It’s only fair”

“Y…yes…of course…keep going…Flutterbunny!” Luna moaned as Fluttershy began to use her fingers to play with Luna swollen clit “Oh….yes…you’re a dirty little cheat, Flutterbunny…I didn’t say you could use your fingers but damn it…oooo…feels so good!”

There then came a knock on the door “Go away!” Fluttershy snapped.

“Fluttershy? Are you alright in there?” Rarity asked as she stood outside, she had heard moaning and other strange sounds coming from the cottage “Please open the door…”

“I said go away and…” Fluttershy began but noticed the look on Luna’s face “On second thought give me a moment, Rarity” Luna stepped off Fluttershy’s face and hid in a cupboard, as Fluttershy pulled the towel around herself but Luna then slipped a piece of paper with instructions under the cupboard door “Yes, Mistress” Fluttershy whispered as she grabbed the paper and then walked to the cottage door “Rarity, I’m so sorry I didn’t mean to snap, you caught me at a bad moment and…well I couldn’t help it”

Rarity was a mare with the perfect body and she always seemed very alluring. However at this point, she was looking at Fluttershy in shock as she walked in and sat in a large arm chair “Darling! What have you been doing?! I heard a lot of loud weird noises like somepony…” she paused, a look of realisation spreading across her beautiful features, it however quickly gave way to a look of horror and Rarity mumbled “You weren’t…masturbating were you?”

“Mmm, no I was having sex with Princess Luna” Fluttershy said calmly smiling following the instructions on the piece of paper “I was licking her lovely slit” she licked her lips to add to the effect.

Rarity released a nervous laugh “Y…Your joking..ri...right?” she stuttered “I mean you wouldn’tahhh!” Rarity released a small scream as she felt a pair of hands grip her breasts and she tried to pull away “N..No…who? Pr…Princess Luna! What are you?!”

“Oh fair Rarity…I’m creating a harem and well…how could I refuse the chance to feel your firm breasts?” Luna whispered into her ear and then added “Flutterbunny, here was merely following my orders and now…I want to make you the same offer. Care to join my harem?” she pinched Rarity’s nipples through the fabric of Rarity’s dress and bra as she spoke.

“Oh…no…no…please…stop…I…I’m not into mares!” Rarity snapped as she finally pulled free of Luna and covered her body with her arms “I…can’t…”

“Why?” asked Fluttershy as she stepped forward “I’ve seen the way you look at Applejack…”

“That’s different! I need to find a stallion or my name will be…will be...ruined!” Rarity snarled as she turned on Fluttershy “Applejack!….she isn’t…she can’t be…she is so…” Rarity took a deep breath and said “If you can get Applejack to…um…give you her panties…I’ll join your…harem. I’ll even design costumes for your harem” she looked away as she spoke.

“Oh is that all. I kept Applejack’s panties as a little souvenir” Luna walked over to her saddle bag by the couch and pulled out a pair of green panties with three apples on the front. She then giggled “Oh Rarity, your so naive…quite a few mares in fashion are openly into mares. In fact, I’ve been in Coco Pommel’s dreams a few times….she’s really interested in a certain mare from Ponyville but don’t worry it’s not you. There are also plenty of stallions in fashion who don’t like mares, Hoity Toity for example”

“No! He’s…he’s…” Rarity stuttered.

“He is as gay as the grass is green. As for cock well…I do know a certain mare who could find a spell to help us” Luna said with a sly grin.

“Oh, okay! So curious question who’s Coco’s little crush?” Rarity said finally looking at Luna up and down “Is it Applejack?”

“Um no…it’s me” Fluttershy mumbled as she held up an old letter “She’s been asking me to come to Manehattan so she can show me round” she sighed as she walked up to Luna and kissed her on the lips “It’s so obvious she wants me for a mare friend but…she just isn’t my type”

“Come my little…huh can’t think of a nickname for you…but regardless. Strip…my new cosplay pony” Luna said as Rarity unzipped her dress and let the purple dress fall down her frame. She then removed her bra and last her panties “Truly a sight worth savouring….but Flutterbunny on your hands and knees…let Rarity experience your tongue”

“Um yes…mam” Fluttershy said as she removed the towel and got on the floor in the position her mistress had ordered “Come here, Rarity…let me lick you pussy” Rarity stepped forward, even more shy than Fluttershy should have been and looked away “Oh come on spread your legs a little” Rarity obliged but looked deeply ashamed “Mmm so tasty” as Fluttershy licked the slit.

“OOOO Celestia! Oh sweet Celestia…it feels so good!” Rarity gasped and then she saw Luna who was casting a spell “Wait I thought you said Twilight might know a spell?”

“Oh Twilight…no…she’s too much of a…sexual prune…I was speaking of myself” Luna smiled as the spell made her grow a huge Stallion dick “Now Flutterbunny…I will be gentle I promise” she walked up behind Fluttershy and held Fluttershy’s flank, as she lined up the new member with the timid mare’s slit but then said “Are you ready?” Fluttershy nodded “Okay….ahhh so tight!”

“OH Celestia….your soo big!” Fluttershy moaned as she felt the member fill her and she began to shake “Oh yeah…Rarity…you’ve got to feel it! It’s soo good!” she bucked her hips back as Luna gave a little thrust “Oh my…mmmm…” Fluttershy got back to licking Rarity’s slit “mmm so tasty”

“F…Fluttershy…your tongue feels so good…I can’t…ooohhhh!” Rarity gushed cum as she climaxed, Fluttershy held her mouth open to allow as much of Rarity’s cum into her mouth and Rarity collapsed watching Luna begin to thrust deeper into Fluttershy “Oh…so hot….so sexy…” she reached forward and began to play with Fluttershy’s breasts “Darling….I’ll ensure…your costumes always shows off these fantastic tits!”

Seeing Rarity cum and then playing with Fluttershy’s tits pushed Luna over the edge “Ohh Celestia!” she filled Fluttershy with cum and smiled as she pulled out. She looked at Fluttershy’s pussy as it leaked out some of the cum Luna had just filled her with and Luna smiled “Rarity come clean my cock…Flutterbunny rest for a moment…your creampie is too sexy for words”

“So good” Fluttershy whispered as she felt Luna’s cum inside her, along with Rarity feeling her breasts and she couldn’t help but collapse on the ground as she too climaxed “

Rarity nodded “Yes mistress” she stepped over and got on her knees “Um should I clean it with my mouth, Mistress?” she asked uncertain.

“Oh how cute…your more naive than you let on, Rarity” Luna said as she pushed the cock into Rarity’s mouth “Make sure you get it good and clean…Oh and swallow any cum that spills out”

“Mmmhmm” Rarity moaned, nodding as she felt the huge cock poke the back of her throat and after a few minutes, Luna pulled out, making the cock disappear but Rarity groaned “I wanted that inside my pussy, mistress!”

“I still have three more mares to add to my harem, so I don’t have time and Rarity you’ll be filled soon enough. Flutterbunny, Rarity. I want you in my bedchambers at 6pm tomorrow with these and any toys you can find” Luna explained as she pulled out clothing similar to Applejack’s, except Rarity’s harem outfit was purple with the collar marked with a blue diamond and Fluttershy’s was pink with a butterfly marker on the collar “Now as I already explained…Flutterbunny will be my pet and Raritywill be my Cosplay pony”

“Should I wear a pair of bunny ears?” Fluttershy asked, smiling as Luna nodded and said “Yes mistress”

“I have a few ideas that should help” Rarity said with a smile “See you tomorrow my mistress”

“I look forward to it…rest well tonight because I guarantee…you’ll need it” Luna said as she put her dress back on and stepped out.
