"Hurry, sister, we must begin jogging at once!"

Princess Luna trotted onto the Canterlot stadium's field track. Her eagerness to exercise was understandable. It had been eight months since Twilight Sparkle's coronation; eight months of unbearable boredom and inactivity. With little to do but laze around the castle, the moon princess had picked up the unhealthy habits from her gluttonous sister. Feasts and parties had occupied their time for weeks on end; the generous flow of candy on Nightmare Night had both of them stuffed full for days.

Now the once-slender moon alicorn was round as a blueberry, with a soft, fat belly bulging between the two pieces of her sporty green tracksuit. Luna's tubby flanks jiggled as she strolled onto the packed dirt lanes. She craned her soft neck back, exasparated that her sister had fallen so far behind.

"Celestia, please!"

"Coming..." came the labored reply. Luna's older sister had always been the self-indulgent one, and she had truly
let herself go since the coronation. The sun princess slowly waddled onto the field, already sweating from her jog
away from the castle. Celestia's fat frame dwarfed her pudgy sister; the alicorn's white, cake-swollen belly bulged heavy and wide, squishing and rolling past her massive flanks. Celestia's slender hooves widened to pudgy shoulders and a fat, round rump that squashed and bounced with each step. The princess' neck and chin were padded with flab, leading to chubby cheeks that were already burning red with exertion. Celestia's crown and jewelery were absent, replaced by pink-turquoise sweatbands 'round her hooves and hed that were already damp with perspiration. The sun princess finally clopped onto the track besides her sister, who gave her a pitying glance.

"'Tis less than a week to go, sister. We must work off our extra weight at once!"

Celestia's round, pudgy face fell with sadness. No more late-night cake parties, holiday feasts, or candy binges
for either of them. Equestria needed their princesses back in shape for the coming adventures.

"Yes...of course, Luna. I understand..." Celestia responded reluctantly.

Luna drew her head back in aloof acknowledgement, then began trotting in place. Slowly, she broke into a sluggish
gallop down the track. Luna's pudgy belly bounced and jostled beneath her as each hooffall sent ripples through
her chubby frame. Her chubby rump wobbled up and down around her luminescent tail, each motion threatening to tear
the strained pants of her tracksuit. The moon princess huffed and panted, sweat dampening her workout clothes as
she strained to keep up a moderate pace. After fifty paces she glanced back and shot an angry, panting glare at
her motionless sister.

Celestia sighed and slowly began lifting her hooves in place. After a few slow stretches, she tried to break into a light jog down the track. Her heavily fat frame jiggled and squashed incessantly, and the princess grimaced,
sweating profusely as she pulled her swollen frame forward. Each hooffall sent her heavy belly sloshing forward
before squeezing and chafing against her flabby thighs. The heavy orbs of her rump bulged and jiggled as if they
had minds of their own; each slap of her cheeks threatened to pull her lower half off balance. The alicorn burned
with embarassment as she saw her pudgy sister continue to pull away from her. Beads of sweat began pouring from
her flabby body, soaking her sweatbands and dampening her luminescent mane. The pain and effort of moving her
overfed bulk was becoming unbearable. The sun princess desperately tried to hurry her pace, but could barely
pull along her bulk at half Luna's speed. Suddenly she lost her balance, her body careening forward as her rump
propelled her forward and down. Celestia feared her fat frame might burst right there on the track, but the princess merely collapsed onto her soft belly, panting with exhaustion and sweating buckets, a mere 40 paces from the starting marks.

"Go Princess Celestia! Go Princess Luna!" Shouted Twilight Sparkle from her place in the stands.

"Mmph..." she ended her cries with another slice of blueberry pie stuffed into her mouth.

The newly-minted Princess Twilight had been kept busy in Ponyville for the past few months. However, since her
arrival to Canterlot Castle she'd been sure to indulge in what was left of Celestia and Luna's stocks of sweets.
Spike strolled to Twilight's side with a fresh helping of cherry pie, eyeing the hint of purple pudge on the
newly-minted alicorn's side. "Uh, Twilight? You think you should be out there, too? Being a princess and all..."

Twilight laughed. "Oh Spike, don't be silly. I'm not -that- out of shape."
She glanced over at the track, where a gasping, sweaty Luna had just finished a lap and passed the bloated,
fallen frame of her sister.

"Besides," the alicorn princess remarked, raising another slice of pie to her lips, "a few celebratory sweets never hurt anyone!"
