Celestia arose from her bed, cracking tired limbs and stretching out in preparation for the day. Taking the time to raise the sun, she retied to her bathroom for her normal morning routine.

She had no idea how far from normal it would be.

Twilight snickered as she watched Celestia draw a bath through the crack in the door. Soon, her plan would come to fruition...and sugary sweetness. Holding a bottle of conditioner in one hoof, and the receipt from Rarity's Boutique in the other, Twilight eagerly awaited the inevitable.

Celestia sat back, letting the warmth of the water soothe her aching muscles and put her mind at ease. Reaching up to her shelf, she grabbed her conditioner, squeezing a small amount out and massaging it into her hair. Tingling prickles ran across her skin, giving her goosebumps, and her sight lurched as she pulled herself out of the tub. Collapsing on the floor, she looked up to see the menacingly maniacal face of her once-student smiling back at her. As her legs lost function, she swore she could see Twilight licking her lips.

Using all her strength, Celestia forced out a breath. "W...why?" she shivered, her body beginning to change in earnest, her limbs retracting into her body bit by bit. As her hooves sank into her torso, Celestia could only stare in horror as her body began to form a cylinder and grew lighter. As her flesh quickly converted to a spongy yellow material, her fate became clear. Her head began to shift, taking position atop the center of her now flattened circular body, before forming a smaller cylinder. Her mane began to solidify, becoming succulent buttercream and spreading itself over the top layer of the cake she was rapidly turning into. Her tail suffered a similar fate, becoming icing for the lower tier. As her horn became sprinkles, and her eyes morphed into two large candies, her mind became lost in a sea of bliss and arousal.

In a matter of seconds, it was all over. Celestia was no more - Cakelestia was all that remained of Equestria's most powerful ruler, and Twilight had to fight her urges to lick the frosting right off her mentor's top tier. Placing Celestia's delicious body atop a platter, Twilight made for the bedchambers in the opposite tower, a massive grin on her face. Today was going to be priceless!

Raising her hoof to knock, Twilight quickly teleported back to her room in the castle, leaving Cakelestia to her fate. The door creaked open, the Lunar Princess' eyes growing large as they took in the sight before them. A majestic yellow cake, with two levels sat before her, its pink, blue, and green frosting reminding her of her sister. Celestia could only look on in shock as Luna pulled the trolley into her room, closing the door tightly behind her.

A small note affixed to the top tier of the cake bore a simple message: "To Luna, Happy Early Birthday! - Twilight." Luna let out a loud squee, before dragging a hoof slowly across the frosting, leaving a small trail wherever she moved. As the buttercream coated her hoof, Luna gazed in awe at the sight of the inviting flesh beneath. Yellow, sponge-like material, with a scent as sickly sweet as Pinkie's shampoo filled the Princess' gaze with awe and wonder. Raising her hoof to her face, Luna licked the frosting off slowly, dragging her tongue across her hoof's edge, her nethers trembling in anticipation.

"Oh, Goddesses, yes!" Luna shuddered, dragging her hoof sensually over the cake's surface, tracing lines and shapes into its yielding frosting. Each lick of the frosting brought her closer to being lost in arousal, and as she leaned down to take a nibble, Celestia wished she could recoil and escape. Each lick and touch ran through her with electric sparks, spiking her libido and making it harder to focus on the immediate danger of being her sister's snack.

Luna dragged her tongue across the cake's top tier, taking a generous chunk of the yellow insides with it. She swirled the cake about her mouth, enjoying the feeling of the buttercream sliding down her throat. Celestia, likewise, was clouded by her ecstasy as Luna began to nibble and chew on her delicious body. Luna bit and chewed and bit, tearing chunk after chunk from the cake, nearly finishing off the top tier in a few gulps. Celestia's vision disappeared - her eyes had been lapped up by her sister's enormous tongue and sent to her stomach like the rest of her head. She could feel parts of her splashing into Luna's stomach, the acids breaking her down into base nutrients. Her thoughts became fuzzier and fuzzier as Luna ate more.

Soon, Celestia found it was hard to focus on anything besides her sister's immaculate mouth and the wonders of being eaten. Luna scarfed down the rest of the top tier, leaving the whole bottom open for her pleasure. Leaning down to take a bite, she chomped a big chunk of cake and chewed noisily before swallowing it down with water. She reached out for another bite, failing to notice the blue glow surrounding the rest of her delectable dessert.

Just as Celestia started to lose consciousness, her senses came rushing back to her, a whirlwind of sight, hearing, and sensation buffeting her body. The cake glowed blue, before being engulfed by a bright light, two hooves poking out from where Luna was licking the frosting. As Celestia's body began to reform from the effects of the lotion, Luna reached down for one more massive bite. Her teeth clamped down on something that was soaking wet, and most certainly not cake as Celestia's ass materialized in front of Luna. Luna's muzzle, coated in frosting and sprinkles, was wedged between Celestia's folds, and her eyes were wide with shock.

"C- C- Celestia!?!" Luna sputtered, pulling her muzzle from her sister's pussy with a wet smack.

"Why Luna, if you wanted to eat me, all you had to do was ask." Celestia shook her legs from their numbness, laying down on her back and presenting herself to her sister, pussy juices soaking into the leftover frosting around her clit. "At least have the courtesy to finish what's left on your plate, dear sister."

The guards outside barely had time to register their armor was sailing through the air before they were knocked aside by Luna as she fled her room, wailing in shock and irritation.

"TWIIIILIIIIGHT!"

Twilight snickered in satisfaction from the broom closet across the hall.

"I shall be the butt of your jokes no longer!" Luna poured gallon after gallon of water down her throat, trying frantically to wash off the taste of her sister's pussy, but to no avail.

Celestia, meanwhile, enjoyed a hearty laugh with her protege as they watched the antics. "I'm a big fan of pranks, Twilight..."

"But I daresay this one takes the cake.
