“Welcome, Princess!” Mr Cake said as Princess Luna walked into Sugar cube corner “How may I help you today. I just got a fresh batch of Cupcakes and a couple dozen cookies ready to be enjoyed” Luna remained silent looking around the shop for signs of her favourite party pony but by all accounts there was no sign of her “Are you looking for something?”

“No, I’m looking for somepony, where is Pinkie Pie?” Luna asked walking closer, as soon as she asked the question Mr Cake seemed to sweat and she frowned “What have you done with her?!” suddenly Mr Cake began laughing and pointed to a large cake in the centre of the room “Is that for me? You should know I’m not one for cakes like my sister but I appreciate it all the….wow!”

Mrs Cake had walked in her bra and panties, even Luna had to admit, the plump baker made it work but she then pulled the cake apart and Pinkie fell out dressed in red ribbon. She was dressed like a present “We got word from Princess Celestia dearie and she asked as to prepare this present” she slapped Pinkie’s ass “Also Pinkie was keen on the idea….weren’t you?”

“I loved the idea! Being your little mare of puddings and sex sounded like fun!” Pinkie admitted as she stood up, the ribbon wrapped round her breasts and private parts “So want to open your present?” she asked as she lay on the counter ready for Luna. Luna smirked as she approached her present, the cakes left the room and Luna used her magic to lock the doors but also closed the shutters “I was told to say Happy Birthday, Lulu” Pinkie looked up at her as she then handed Luna a birthday card.

“So you are my present? My my that’s nice of you but I have a very important job in mind for you….my little snack mare” Luna whispered as she opened the card and found a note, as she read the note, she found out Celestia’s birthday present was also a voucher that would mean Celestia would help her with getting another mare into her harem but Luna knew who she wanted “To be honest, Pinkie” Luna laughed embarrassed “I forgot it was my birthday….you know over 1000 years old…birthdays kind of become sort of pointless”

Pinkie gave Luna the world’s worst death stare and said “No birthday is pointless!” she stood up and added “Your under arrest for crimes against parties!”

“HUH?!” Luna asked as Pinkie grabbed her, pulling Luna’s arms behind her back and with a loud click handcuffs went on her wrists “UH! Pinkie! You’re my snack mare…..roleplay mare…that was meant to be Twilight!” she squirmed as Pinkie licked one of her fingers and then rammed it into Luna’s pussy “AHHHH! Okay, okay! I’m sorry…my birthday matters!”

Pinkie smiled but then whispered “You still need to be punished!” she picked Luna up and placed her on a big cake board that had appeared on the counter as she tied Luna’s ankles to the corners of the board but also tied down her wrists “Now for some sweet Lulu cake!”

“Wait no! I don’t want to get my dress dirty!” Luna snapped but then Pinkie pointed to her horn “I could escape but I’m enjoying this” she used her magic to strip herself and make the clothes appear in a corner of the room as Pinkie collected some ingredients “So what’s Lulu cake?”

“Well it’s actually a shop in Manehattan” Pinkie said with a smile and added “I did some guilty research, anyway it’s actually you and let’s start with some sugar!” Pinkie used a sugar shaker to coat Luna’s body in sugar, Pinkie smiled as the white flower mixed into Luna’s fur and made her coat a slightly greyish blue colour “MMHHH! You look good enough to eat! But we’re not finished, now for some chopped almonds and Marzipan!” Pinkie proceeded to sprinkle chopped almonds over Luna’s private parts and her neck but then got a bowl of freshly made Marzipan and using a small spoon and knife used it to draw Luna’s outline on the board “There I love marzipan! It’s so nice and rich!”

“Why are you doing this?! I’m so wet!” Luna moaned but then gasped as she saw Pinkie sculpt the remaining marzipan into a ball gag “W…W…Wait I don’t like marzipan!” Pinkie then pushed the ball into Luna’s mouth and tied two lengths of edible rope to tie the ball in place “MMMMMM!”

“There! Now you’ll be nice and quiet while I finish!” Pinkie said as she traced a finger over Luna’s pussy and sucked it “MMM very nice…but it’ll take more than almonds to seal in the flavour!” she then got some prepared strips of Icing and laid it on but also around Luna’s pussy “There some icing panties!” she laughed but then thought “We need something for your breasts! I know…some squirting icing will do and I can’t wait to…” she noticed something you’re horn…why’s it glowing?”

Luna smirked and before Pinkie could react, she felt herself tied down with food all over “Sorry, Pinkie but as soon as you said I had to be punished I used my magic to trick you…I just used one of your dreams to make a Pinkie cake! It was like I allowed you to imagine how to make a Lulu cake but did it to you as you dreamed” she knew what to do with the rest of the ingredients. She used a piping bag of Icing to cover Pinkie’s breasts but also covered Pinkie in a thick layer of icing elsewhere till only Pinkie’s head was visible and the icing made a sexy outline of her body “There you look like a delicious cake but it’s a little plain so now what to put on top?”

Suddenly Luna noticed Pinkie eating the marzipan gag “MMM that was tasty! I wish we had more marzipan like that!” she said as Luna climbed up on the board and sat on Pinkie’s face “Okay!” Pinkie began to lick Luna’s juices and soon Luna squirted her cum onto the cake “Won’t that ruin the flavour of the cake?”

“Nope…it’s a sex pinkie cake and I won’t be the only one enjoying it!” Luna said as she used small candies to draw out an image on the icing of Pinkie in a multi-coloured slave outfit “Who better to enjoy this with than the mare I want to share my birthday cake with Twilight” she covered Pinkie with a table cloth and whispered “When she sees you…like this…she’ll agree”

Spike knocked on the door and walked in when Luna opened it “So that’s Pinkie…ready to please Twilight?” Luna nodded as Spike mumbled “So Rarity will accept right?” Luna shrugged “What?!” she shrugged again.

“She is in a 50/50 position Spike…I can’t say if she will” Luna said honestly as Spike walked up and cupped her breasts “You naughty dragon….anyway oooo that feels good…um sorry but Twilight will likely react negatively to this and with a little convincing she may agree” Luna then handed Spike Celestia’s voucher “I have also decided to add Starlight at the same time…her hot body is too much to pass up on…” she began rubbing Spike’s crotch with her hand as she added “I also wish to um Spike…why are you..oohhhh!” she felt Spike push his hard cock into her pussy “S…Stop! I need to…ooooo!”

“Don’t pretend…you love it! That’s why you added me!” Spike said as he then added “Before I forget…I let Rainbow go home for some rest and she told me to keep you happy” he then added “So how are we going to get Twilight and Starlight?”

Pinkie said from under the table cloth “Um Princess…I have an idea of how to use me to get Twilight and Starlight” she felt wonderful as Luna’s Birthday cake but added “You need to surprise them….let them find me without guiding them here”

“That’s a good idea but how?” Luna asked as Spike inserted a claw into her vagina and she moaned “OOOhhhhh Spike…how Pinkie?”

“I think I know a way….we could get Mrs Cake to tell them, that they can’t find me and could they help” Pinkie said and Luna raised an eyebrow “Twilight and Starlight will come here first to look for clues and find me”

“Well we could try it?” Luna said as Spike finished and filled her with his rich cum “AHHH ohhh that felt so good” she got off Spike’s cock and added “Mrs Cake…I have orders for you” Mrs Cake ran in and bowed. Luna explained the plan and told her to lock the front door behind Starlight and Twilight when they got to Sugar cube corner.

"It'll be my pleasure dearie" Mrs Cake said as she walked back into the kitchen, got changed and left for the castle.

Luna then had an idea "Spike! Go get Rainbow cum, Raricow , Flutterbunny and Appleslut! I have changed my mind...our first meeting will be right here!" she said as she turned to Pinkie "Your nickname shall be Candy Pinkie!" she then added "Once I have all eight of you...Celestia will join Rainbow cum as our slave mare!" she used her magic to make an image of Celestia appear above them in chains and sucking Spike's hard cock "Won't that be fun?"

"Yes" Pinkie and Spike said together as the Celestia in the image kissed Applejack's pussy in complete submission to the harem.

"Her Harem members will be given to each of you as toys" Luna said evilly as her eyes changed to those of Nightmare Moon but with one difference her eyes were a dark pink.

Author's Note

I'm sorry if this wasn't very good but the amount of times I rewrote this chapter was ridiculous so I just took a stab at it and it didn't turn out well. Next chapter Twilight and Starlight become a part of the Harem. I'm can't think of nicknames for them thou, so suggestions please?
