Celestia's Weight Gain Experiment

“Sweet mother of me, I’m getting heavy.”

The scale’s optimistic report cheered Celestia up.

“They are both grown mares. If they think they’re getting too big, obviously they can say something. It isn’t my place to criticize, after all. I’m sure it’ll be fine.”

Celestia placed her quill and journal on her desk and turned towards the exit.

“Heh. ‘Grown mare.’ More like ‘growing mare.’”

She snickered to herself as she felt her pot belly shift and sway between her legs and her chubby thighs jiggle with each step.

Raven had mixed ideas in her head about the whole affair. She had lived and worked at Celestia’s side for years now. So, she was the first to realize that Celestia’s “side” was bigger than ever. Of course, she knew that her ruler’s stomach was flabbier, her butt was bigger, and the sheer intake of food had transcended any and all normal proportions. So, who could really blame her for having an extra cupcake? Who could really blame her for munching on chocolate chip cookies while her monarch snacked on baklava – her thick flanks squished within her throne?

The result was a little pony swelling by the day, perhaps distracted by the heavy workload she was meant to complete. As Celestia transformed into a bulbous shape, her belly swelling and her butt expanding, Raven did her due diligence by expanding into a sweet little butterball herself.

Celestia was not ignorant to these changes. Raven could see them too. In the both of them,. It was impossible not to notice. She sat in a throne meticulously crafted to be wider and more accommodating. It worked at first. Then, gradually, she felt the familiar tightness. One day, as her fabulous flanks were awkwardly planted between an increasingly inadequate pair of armrests on her plus-sized throne, she finally broached the topic.

“So. Raven.”

“Yes, your highness?”

“Do you think…perhaps…there’s been a few too many treats at Canterlot Castle?”

Raven blushed, knowing exactly what her overlord had meant. Look at her. Look at both of them. For goodness’s sake, the modest little royal secretary was fatter than she had ever been in her life. Her belly awkwardly protruded between her legs. Her flabby flanks formed a cushy seat. Her neck and cheeks formed chubby little pillows. And even at this rate – this spectacular fattening that would have put most ponies to shame – it was nothing compared to the mare that had caused it. Celestia was bursting out of her seat. Under the ever-more-chubby secretary’s gaze, Princess Celestia’s laborious, grunting posture had (at first) fit within the armrests of Equestria’s most exalted seat. With care, she could maneuver the sun-decorated orbs into the ornate throne. But that was many, many pounds ago. It had since become embarrassing. Celestia’s ass protruded on either side, spilling outwards in squishy, yummy expansions. It was obvious she could no longer fit. But it was not Raven’s place to argue. It was not her place to contest. She considered the cupcakes she had recently incorporated into her daily routine. Then the doughnuts. Then the massive breakfasts, lunches, dinners, and desserts. She thought about the fact she no longer cared about ‘watching her figure.’ The rate of growth elicited neither shame nor alarm.

She considered the notion of curbing her precipitous growth. What she said achieved exactly the opposite.

“Absolutely not, your majesty. In fact, I believe there has been an unfortunate shortage in our commissary, and I would like to rectify it.”

“Oh good, I had been feeling the same way.”

Celestia’s massive stomach growled as if to emphasize the point.

“In fact, your highness, I was thinking that we might double the routine shipments from our usual providers. Your dietary changes are causing some shortages, after all.”

In the back of her mind, Celestia mused that such upfront commentary from her secretary was ‘supposed’ to be offensive. In any other situation, she might have felt bad about so obviously, so transparently becoming fat. But that emotion simply did not manifest. For crying out loud, Raven herself was contributing to these ‘food shortages.’ Celestia persuaded herself, noting how her belly under hoof was as swollen and exaggerated as it ever had been.

“Make it triple.”

Celestia treated this exchange with a mixture of bewilderment and joy. She took no steps to prevent the fact that her most loyal worker – growing fatter by the day – put in an official request to increase food shipments to Canterlot Castle. The results were predictable. Under nopony’s order, with no inclination but her own observance to Celestia, Raven Inkwell’s once-subtle weight gain exploded. She became the fattest member of Celestia’s entire staff.
