“Now Twilight, open your mouth.” Celestia ordered. Twilight shook her head, still struggling her way out of Celestia’s spell. “Come on, open it.” Celestia said again, hovering a slice of cake in front of her. Twilight shook her head again in denial. “I’m telling you to open your mouth!” Celestia roared, pushing the slice on Twilight’s mouth.

Twilight growled. She could feel the cake trying to enter her mouth, but she kept her mouth sealed. It was quite hard since it was her favorite: Maple syrup cake.

“Twilight, don’t make me do it.” Celestia warned Twilight, trying once again to press the cake on her mouth. Twilight shed a tear from her left eye, still closing her mouth as hard as she could. “Fine, be that way.” Celestia sighed.

Celestia’s horn glowed a little brighter. Twilight could feel her mouth was being forced to open, she tried to resist, but once again, Celestia’s magic was too powerful for her. Finally, Twilight opened her mouth wide open. Celestia then pushed the cake in. “Now chew!” Celestia told her. Twilight began to whimper, almost choking with the cake in her mouth. She had no option but chew on her favorite flavored cake.

Twilight chewed the cake inside her mouth, slowly swallowing it. She felt that delicious maple syrup flavor she loved so much, the cream, nuts, almonds and the frosting. Her body began to relax. Why does this feel… so good? Twilight wondered herself, chewing the last piece of cake inside her mouth. As soon as she finished with the cake, she tried to catch her breath, heavily breathing with her mouth.

“Good girl, Twilight.” Celestia smiled, looking at her precious student. Twilight opened her eyes and stared back at her mentor. She had the same warm and peaceful smile she always had.

“Princess... stop… please…” Twilight could hardly talk, she coughed a little.

“Stop? But we’re just getting started!” Celestia chimed, levitating another slice of cake and placing it inside Twilight’s mouth. Twilight tried to close her mouth before the cake could get in, but it was too late, once again, she had no option but to eat the cake.

Twilight wasn’t struggling her way out of Celestia’s spell anymore. She kept on chewing the new slice of cake. It wasn’t the same maple syrup cake from before. Instead, it was a coconut-vanilla cake, with cinnamon and chocolate. Twilight once again felt the flavors in her mouth. She felt the cinnamon and chocolate scattering all over her gums. She moaned with pleasure once she swallowed the last piece of the cake.

“So Twilight… do you like it?” Celestia asked Twilight, who was licking the cake outside her mouth with her tongue.

“Y-yes…” Twilight confessed. A grin on Celestia’s face was formed. “Princess…”

“Yes, my faithful student?” Celestia said.

“M-more…” Twilight muttered.

Celestia chuckled. “Alright, Twilight.” She levitated another piece of cake from the pile and placed it inside Twilight’s mouth. She was surprised to see Twilight devouring it. Twilight was done with the piece in a matter of seconds.

“More! Please!” Twilight begged, licking as much cake as she could from outside her mouth. Celestia levitated three slices of cake. She gave Twilight one slice, waiting for her to finish it so she could give her the other slices.

I love it! I love it! Twilight was furiously biting the cake in her mouth, she loved the explosion of flavors that were forming inside her. “Don’t stop Princess! Please more!” Twilight yelled. Celestia gave her another slice, looking at her student with a big smile.

“Please Princess! More! More!” Twilight moaned. She wanted more, she desired more cake, and she wasn’t satisfied yet. Celestia placed more cake inside Twilight’s mouth, which didn’t last long since Twilight was eating it faster than before. “More! More! Princess! Please more!” Twilight moaned out loud again.

“Okay, I think you don’t need this anymore…” Celestia’s horn stopped glowing and the magical aura around Twilight disappeared. Twilight fell onto the floor and dashed towards the pile of cakes.

Twilight couldn’t decide what to eat first. “White chocolate, strawberry, lemon, honey… which one?” Twilight looked at the cakes once again. “Oh, whatever!” She began to devour the cakes, giving random alternate bites to different cakes. She had small pieces of cake all over her mane.

“Good girl, Twilight…” Celestia whispered to herself.

“These cakes are delicious! I love them! I could keep eating them forever!” Twilight exclaimed. She kept eating the cakes, filling her mouth with different pieces of cake, chewing them together. “Princess… I” She couldn’t hold it anymore. She let out a loud moan of pleasure from all the delicious flavours in her mouth. Twilight laid on the floor, catching her breath.

“Oh my, Twilight…” Celestia walked towards Twilight. She sat down and lowered her head, resting it over Twilight’s back. “My faithful student, I’m proud of you.” Celestia whispered to Twilight’s ear.

“Thank you Princess…” Twilight replied, rubbing her head on her mentor’s neck.

“You’re welcome, Twilight. I hope you now understand why I love cakes so much.” Celestia softly rubbed back.

“I do now, Princess, thank you again for this amazing experience.” Twilight closed her eyes, feeling the soft coat of the Princess on her face. “I love cakes, Princess.”

“I love cakes too, Twilight.” Celestia replied, closing her eyes as well, feeling the little unicorn’s body heat on her chin.

Now’s my chance! Twilight suddenly raised from the ground, pushing Celestia and stepping back.

“Whoa!” Celestia fell on her back, trying to assimilate what just happened.

Twilight ripped the necklace with her magic and the pearl fell to the floor.

“The pearl! I forgot it!” Celestia yelled, remembering why she was in the library in the first place: To steal Luna’s pearl.

“Too late, Princess!” Twilight stomped the pearl with her hoof, breaking it. Suddenly, white smoke began to appear from below her hoof. Right! Princess Luna said I had to run as far as possible from here! Twilight ran towards the front door.

“Twilight! Get back here!” Celestia stood up, trying to cast an spell on Twilight, but she couldn’t focus because the white smoke began to envelop the entire library.

“I’m sorry Princess!” Twilight opened the door with her magic, running outside and closing it on her way out.

The white smoke surrounded the entire room.

-----

“She’ll be here any minute, I hope Twilight Sparkle found her.” Luna said, waiting patiently for Celestia’s arrival in her room.

White smoke began to emanate from the floor. “She’s here!” Luna exclaimed, her horn began to glow.

The white smoke quickly surrounded Luna’s room and Celestia appeared from it. “Now!” Luna shot a beam of magic from her horn towards Celestia. The smoke began to fade away.

“Luna! What’s this!” Celestia yelled, she tried to move but she couldn’t even shake her head.

“My stunning spell, I’ve honed it for years. And finally, I caught you!” Luna replied, walking towards her immobile sister. “You ate my special cake!” She raised her hoof, pointing at her face. "Why did you do it?"

"I was hungry, and your cake looked delicious." Celestia answered. "Oh yes... it was delicious."

"You still ate MY cake! You had no right to do so!" Luna yelled.

“So what if I did? What are you going to do?” Celestia mocked her sister.

“Oh, I have plans ‘Tia…” Luna walked next to Celestia, moving her mouth close to her ear. “You’ve been a very bad sister…” She whispered.

“W-what are you planning to do?” Celestia nervously asked. Her sister was starting to scare her.

“We will have some fun together… and you will taste some of my ‘Luna Cake’. I’m sure you’ll love it.” Luna chuckled, sticking her tongue out of her mouth, licking her sister’s ear.

Celestia cringed.

-----

A bell rang.

“Oh Celestia! My Luna Cake is ready!” Luna chimed, opening an oven’s door with her magic. She withdrew a big, royal blue cake from the oven. She placed it over a table and added the frosting to the cake.

“Finally!” Celestia exclaimed.

“Now, it’s ready.” Luna said, grabbing a slice of cake with her magic and hovering right next to Celestia. The dark blue aura was replaced with Celestia’s faint yellow-white aura.

“Thanks Luna! You’re the best sister ever!” Celestia said, smiling at her sister.

Luna chuckled, looking at her happy sister. “You’re welcome ‘Tia, and sorry for using the stunning spell.” Luna rubbed her left hoof against her right hoof.

“Oh don’t worry, I promise to stop obsessing over cakes after eating this last one.” Celestia turned her stare to the cake, giving it a soft bite.

“I know you will ‘Tia…” Luna said. “I know you will.” She whispered to herself. “You’ll never eat my cakes again…”

-----

“So Princess Luna, is Princess Celestia going to be okay now?” Twilight asked. She was sitting on Luna’s bed, using her magic to brush Luna’s mane with a comb.

“She will surely be, thanks for your help Twilight Sparkle.” Luna replied. “In fact, I think she will stay away from cakes for a good time.” Luna laughed.

“Why? Did you add something to the cake you prepared?” Twilight asked, putting the comb down. “Come to think, since I arrived here, she hasn’t come out of the bathroom.”

“Let’s just say… chocolate laxatives are a good cake condiment.” Luna chuckled.
