“Did you just SOIL yourself?” the words couldn’t have been charged with more disgust and revulsion.

Fluttershy felt her body tense up, coiling into a tight ball of nerves. She shakily looked up at her caretaker, a look of fear and humiliation covering her face. “U-uhm, n-no,” she so weakly responded. She hardly sounded convincing, but it was the only thing her scattered brain could manage in such a short amount of time.

Rarity scowled at the obvious lie. “Turn around. I’ll check, myself.”

After giving Fluttershy only seconds to respond, Rarity proceeded to magically lift the pony around with the use of her magic. The yellow pegasus gasped a meek squeak as her entire body was spun around in the air and her diapered rump was lifted upwards.

An offending odor fouled up the air around her as her diaper was inspected.

Rarity kept her distance from the repulsive diaper, standing just close enough to inspect the brown stained diaper. Her nose curled in disgust as the smell of the poopy diaper only seemed to get worse. She could hardly bare to look at the bulging thing as a heavy, stinky load inside of it pulled it’s seat downwards with a hefty weight. She dared not touch the offending garment, but still upheld her duties as a caretaker to give it a thorough look over.

“Just as I thought,” Rarity sneered, letting Fluttershy’s body drop to the ground with a padded thump, “and what do you have to say for yourself?”

“I-I’m...sorry that I...soiled myself,” Fluttershy answered with a quiet voice.

“I don’t believe you,” Rarity sternly snapped back, “but you will be soon.”

Fluttershy’s blood ran cold as Rarity scowled back at her. She knew just what was coming. With a glow of her horn, Rarity summoned her day bag, a sort of bag of tricks that contained a wide assortment of naughty tools and items. There was no telling what secrets the bag held behind the single large zipper that ran across it’s top. It likely contained a number of wonderful items, but Fluttershy was smart enough to know exactly what Rarity was retrieving.

Out from the day bag’s main compartment floated out a diamond encrusted spanking paddle. The paddle was the dazzling crown jewel of Rarity’s collection. It was made of a dark, ebony wood with diamond shaped holes cutting through its wide, flat blade. The shaft was wrapped with a beautifully soft velvet that had sparkling diamonds embedded into it.

Fluttershy assumed the position. It was a position she had taken a dozen times before. Back facing Rarity, head lowered to the ground, and her hooves far away from her diaper so she wouldn’t try to shield her vulnerable rump during it all. It had taken quite a couple tries for her to learn how to properly accept a good spanking from her caretaker.

“I think twenty spanks will do,” Rarity rasped, “surely you know the drill by now. Count each spank and if you lose track I add five more. Am I clear?”

“Y-yes Miss Rarity,” Fluttershy whimpered.

Gripping the paddle tightly with her light blue magic, Rarity reeled it up into the air and swung it down hard into Fluttershy’s diapered bottom.

Such unexpected force was behind the first spank that Fluttershy struggled to keep her footing upon impact. She let out an involuntary gasp as the strength of the paddle squished the mess in her diaper around. “O-one!” she exclaimed, gritting her teeth with a shiver.

After she took a short pause to admire her submissive charge, Rarity pulled the paddle back up for another hard swing. This one like the last, made contact with Fluttershy’s diapered rump with a padded thud.

“T-two!” she could hear Fluttershy sputter out.

The diaper absorbed most of the power behind Rarity’s swings, but a spanking like this was never solely intended to bring pain. After the sixth or seventh swing things became sore, sure, but Rarity hardly meant for her spanks to hurt.

By the tenth swing, Fluttershy was starting to get into the rhythm of things. Every swing of the paddle shook her body as her hooves dug into the carpeted floor.

The soiled diaper, once bulging with a lumpy mess, became pancaked and flat as Fluttershy’s shame was pressed back into her with each swing of Rarity’s paddle. In a strange way the feel of her own mess being squished back into her felt naughty, pleasurable even. She was so caught up in how wonderful it felt that she barely even noticed the next hard spank.

“T-twelve!” she hastily stammered out in hopes to she would recover from her daydreaming.

“Way too slow!” Rarity barked, “twenty five spanks it is!”

Fluttershy cringed as her punishment was increased. She made sure to call out every spank after that. Fourteen, fifteen, all the way up to twentieth. Eventually the combined efforts of the subtle pain from the spankings and the shame of wearing a poopy diaper had taken its toll on the padded pegasus. This humiliation and burning discomfort amounted to a swelling of tears that came dangerously close to breaking around the twenty-second spank.

She thought she could keep it together for just three more spanks, but when the paddle came down once again, slamming against the gooey insides of her flattened diaper, Fluttershy felt the dam break. Tears held up for so long finally escaped her control causing her eyes to water and whimpers to shake her voice.

“Twenty-three!” she whimpered out, almost being unable to between the gentle sobbing that had started.

“Almost there, darling,” Rarity answered as she pulled the paddle up once more, “just two more. Try not to lose count.”

“Twenty-four!...Twenty-five!” Fluttershy called out the last two spanks seamlessly. Even with her face wet with tears, she was able to count them off without a hitch. Things somehow seemed easier now that she was no longer holding back her tears.

When everything was done, Rarity pulled Fluttershy into her arms for a big hug. Despite the terrible odor that hung over the diapered pony, Rarity kept her charge close in a loving, post-spanking embrace.

“I-I’m so sorry!” Fluttershy repeated, this time with tears streaking her face.

“I know you are, honey,” Rarity answered, patting the pegasus’s back in a rare show of affection. She calmed the crying pony down with some gentle pats on the back, coupled with a gentle rocking from side to side.

Despite her tears, Fluttershy felt better about the whole thing. She knew the punishment was rightly deserved and everything was made right with the calming aftercare she received after the fact. She could feel her tears drying up as she hugged in closer to Rarity’s warmth.

The two ponies sat there on the floor like that for a good twenty minutes without moving. Even as the terrible odor of Fluttershy’s diaper filled the room, Rarity kept her close, rocking her and keeping her calm. Eventually Fluttershy seemed to settle down as her whimpering began to quiet and her tears slowly stopped.

“Now...” Rarity began as she started to turn green around the gills. ”if you would be so kind...”

Fluttershy nodded understandingly and mercifully broke away from their long winded embrace. She retrieved an extra diaper from the open package and waddled off to the connected bathroom. “I-I’ll be right back,” she meekly stammered out, finding a small smile growing on her face. She couldn’t wait to do that all over again.

Author's Note

This story almost grew large enough to be its own separate thing, but I figured since it was inspired by the three word prompts and sort of lacks a proper grounding in setting it would stay here for the time being.
