>Rarity, Rainbow Dash, and Fluttershy received an invitation to Sugarcube Corner in their mailboxes.
>The invitation read: “Hi guys! I was wondering if you could come over. I’ve been practicing the Marzipan Mascarpone Meringue Madness cake recipe that the Cakes used.”
>It continued: “Aside from me, you three were really the only other ponies who got a taste. I was wondering if you could help compare it for me. Love, Pinkie”
>Instantly remembering the deliciousness of the cake, they heartily accepted the invitation.
>They all reached the candy store, and eagerly knocked the door. Fluttershy was already fluttering with excitement. 
>Pinkie answered, and greeted them nervously. “Hey guys. I guess you’re here for the taste test.”
>They happily nodded. “Well then, let’s go upstairs. The cake is in my room.”
>“Wouldn’t it make more sense for the cake to be downstairs and easier to get to?” Rainbow asked.
>Pinkie lied. “Well, the Cakes were pleased that their cake won the competition and they wanted to start making some for Ponyville. We wanted to keep it a secret until we got down the recipe again.”
>They entered Pinkie’s room and saw the table with many miniature MMMM cakes on it.
>The three ponies took their seats. “I’m sorry.” Pinkie stammered as she closed the door and blocked it.
>“Now we can begin.” Twilight Sparkle said, revealing herself from behind the curtain. The three tasters turned their heads in surprise.
>”Twilight. What a surprise.” Fluttershy squeaked. “Did you get invited too? The cake was delicious! We can’t wait to try it again.”
>”Yeah, I bet it WAS delicious.” Twilight muttered. “I wouldn’t know. You all were the only ones to get a taste!”
>”Well come on and taste these.” Rainbow suggested.
>“But they’re missing the most important ingredients.” Twilight said as the three ponies started to shrink.
>Twilight picked up the tiny ponies with her magic, and lodged each into a miniature cake.
>”Pinkie, did you know about this?” Rainbow angrily yelled at Pinkie. Pinkie started to cry.
>Twilight put her hoof on Pinkie’s back. “She agreed to do this so I wouldn’t have to punish her as well.” The tears streamed down Pinkie’s cheeks. “I’m sorry.” she whimpered.
>”Don’t worry. They’ll be fine in the end; I didn’t set this up to kill them, after all.” Twilight comforted her. “This is just to teach them a lesson.”
>”I-I’m not going to do it.” Pinkie mustered up her courage. “You can’t make me!”
>Twilight gave an evil smile. “That’s where you’re wrong.” She said. She forced Pinkie to look at her friends as she cast a similar version of the ‘want it need it’ spell on them.
>”Now eat.” She commanded. Pinkie hypnotically licked her lips, and sat down at the table.
>Pinkie at an empty miniature cake, and then turned her attention to the one containing Rarity.
>”Twilight, surely we can talk this over like civilized ponies.” Rarity panicked.
>”Nope.” Twilight simply replied.
>Pinkie brought the miniature cake to her mouth, and ate out the sides. When she reached the center, she began to lick Rarity. 
>She dropped Rarity into her mouth and began to play with her, tossing her with her slippery tongue. Rarity let out one final scream and was swallowed.
>Pinkie then picked up Fluttershy’s cake. Fluttershy began to cry.
>”Don’t cry, Shy. You’ll make the cake all salty.” Pinkie said. She quickly devoured the cake and tossed Fluttershy in the air.
>Were she a better flyer, she would have been able to fly away before Pinkie closed her mouth.
>Pinkie began to suck on Fluttershy; she couldn’t help but enjoy the weeping pony’s struggling as she slid down her slippery tongue and down her throat.
>Done savoring Fluttershy, Pinkie finally turned to Rainbow. “Last one.” Twilight taunted.
>”C’mon Pinkie, snap out of it! Can’t you see what you’re doing? Fight!” Rainbow pleaded to the giant pink pony.
>Pinkie halted for a moment, and attempted to fight her want to devour. Twilight overpowered Pinkie’s will and used her magic to make Pinkie’s tongue touch Rainbow.
>Pinkie finally gave in, and forced the entire small cake into her mouth.
>Rainbow flew around the inside of Pinkie’s mouth, dodging her teeth and her tongue. The mixture of Pinkie’s saliva and tiny bits of cake slowly forced the Pegasus down.
>Unable to use her wings, Rainbow helplessly collapsed onto the soft tongue.
>”It doesn’t feel so bad.” She told herself as she slid around Pinkie’s mouth.
>Pinkie finally gulped rainbow down. Twilight sat down besides her.
>”Excellent job, Pinkie. Now I can finally get to see what the cake finally tastes like. She gleefully floated some of the cakes to her.
>”I can’t wait to- What?!” Twilight was surprised as she began to shrink too.
>She looked over at Pinkie, who was looking at her with delight. With all her friends finally eaten, pinkie was able to break the spell.
>”Now it’s your turn Twilight.” Pinkie giggled. “I hid shrinking powder in the curtain.”
>”B-but everything was going so well, and why would you even want to eat me?” Twilight panicked.
>Pinkie raised her voice.”You think you’re so smart, solving that mystery like it was nothing and shoving poor Pinkie to the side when you were investigating!”
>”If you were a real smarty-pants, you should have chosen Applejack.” Pinkie mocked. “She probably would have easily agreed to do this.”
>Dumbfounded, Twilight just sat there as Pinkie lifted her up to her face. “Now you get to feel what you’re putting your own friends through.”
>She opened up her mouth once more, and placed Twilight on her tongue.
>Twilight became excited as Pinkie began to stroke her privates with her giant tongue.
>”Hmm.” Pinkie teased. “I never knew you enjoyed this so much.”
>She continued to stroke Twilight until she was forced to orgasm.
> “Mmmm. Juicy!” Pinkie exclaimed as she finally swallowed the pleasured pony.
>Feeling hungry, Pinkie turned to the table that was still laden with numerous leftover cakes.
>”Don’t worry guys.” She said. “You’ll be able to eat all the cakes you want. Twilight said she’d keep you all safe so you’ll all be out in no time!”
>Pinkie happily resumed munching on the cakes.
