Equestria's Diapered Deeds

It was a rather quiet night in Canterlot. The shops had closed, and most of the city's residents were retiring into their homes for the evening. For one of these residents, however, her night was just getting started.

Moondancer was considered a recluse by most of the ponies who knew her, and there were very few who could get her to come out of her shell, the most prominent of these few being the princess of friendship, Twilight Sparkle. Everypony assumed that this had something to do with Twilight's innate capacity for friendship, the very qualities that Celestia saw in her that led to her ascension to royalty.

Little did anypony know that the reason was far more personal than that.

"Oh, Twilight," Moondancer muttered to herself as she lay on her bed, her fingers lightly dancing across her sweatpants, teasing her nether regions with the faintest of stimulation. "I've needed this for so long, Twilight." Her fingers pushed against her leaking pussy even harder than before. "Please," she begged, "take me, I'm all yours." Moondancer slowly turned over, exposing her ass to her imaginary lover and teasing herself even further.

"What's that? You want me to take my pants off?" she asked playfully. "Whatever you want Twilight." Moondancer gently tugged down her sweatpants, revealing a thick lilac diaper adorned with the violet princess's own cutie mark. "Oh, this? This is just something I like to wear around the house," she explained, caressing her hand against the front of her undergarment, "so I can keep studying, you know?"

Moondancer's continued to please herself, her one-sided conversation escalating with her arousal, "Naughty? What do you... oh you're right. I'm such a naughty girl. *mmph* How could I have ever considered something so dirty?" Moondancer leaned forward, resting on her breasts and lifting her ass in the air, further exposing her diaper her invisible audience. "You want me to be even dirtier? I don't- oh, gosh Twilight, I *hah* I don't think I could do that, that would be so embarassing." Moondancer's moans grew louder and louder as she lost herself to her fantasy. "What do you have there Twilight?" she inquired, levitating a vial of a soft yellow potion over to herself. "You want me to drink this? I guess I could," she conceded as she gulped down the entire potion.

Within seconds the nerves in her bladder set alight, eager to release their newfound contents. "*HAH* Twi- Twilight, that's *mmrph*, that's not fair! I can't hold this for very long!" Moondancer cried. "Oh fuck, I'm gonna pee so much Twilight!" With that vulgar utterance, her bladder burst, sending streams of hot piss spraying over every inch of the diaper, soaking through so much that her diaper already began to leak. Moondancer felt humiliated, but relieved, and happy that she could've pleased her princess with something so demeaning.

"*Hah*, oh Twilight, you're right, I'm such a messy girl." Moondancer confessed. "Yes, yes, I love being a messy girl, it feels so good!" Moondancer's diaper was fully stained yellow, the slight leaks turning to full streams running down the sides of her legs, forming a small puddle beneath her. Her voice began to give out as the last of her piss leaked out of her pussy, her fully soaked diaper large enough to force her legs apart.

"Did... Did I please my princess?" she sheepishly asked. "You still want more? I don't know what more I can do," she whined, levitating a different emerald potion before herself. "Another one? I don't think that's a good idea Twilight... of course I want to please you... I- oh, okay Twilight, I'll do it just for you."

Moondancer drank her next potion, and felt her bowels expand with the contents it provided. "Oh, Twilight, you want to see just how messy of a girl I can be? Is that what you want from me?" Moondancer continued to play with her pussy as she felt her ass pucker, readying itself for the massive log waiting to be released from her body. "Oh, Twilight, do you wanna watch me poop my diaper? Do you want to see me make such a mess of myself?"

Moondancer's self-deprecation was soon replaced by a string of moans as her anus parted and the turd made its way into her waiting diaper, tenting it out and forcing its way anywhere it could. Moondancer's roleplay didn't end though, as whenever she could form coherent words she begged her audience not to take their eyes off of her.

"I'm doing it, Twilight! I'm shitting myself, just like you wanted, and you were right! It feels amazing, I don't want it to stop! PLEASE DON'T LET IT STOP!!!"

Moondancer's orgasm came crashing into her just as the last of her shit tapered out of her ass, her final cry calling out to her fantasy lover. Her body convulsed as her climax wracked her every nerve, her pussy gushing and soaking what little of her diaper had managed to stay dry. She soon collapsed forward, resting upon her chest and knees as she struggled to regain her strength.

"Mhmm, Twilight," she murmured as she slowly turned over to lay on her back. "Do you see what you do to me? Are you happy with what I would do for you?" She slowly undid the tape at her waist, opening her diaper and exposing the mess she had made of herself. "I hope you like it. It was all for you." She grabbed the front of the diaper and secured it back around her self, feeling a small pang of arousal from the shit shifting and contacting parts of her it hadn't reached before. She slowly rose to her feet and climbed into her bed, content to wrap herself in her blankets and turn in for the night.

Twilight was reading at the map table when she got the knock at the castle door. Setting the book upon the table, she navigated to the foyer to answer, finding a certain cream-colored unicorn waiting on the other side.

"Oh, Moondancer! It's so nice to see you! What can I do for you?"

Moondancer shifted her legs, a very soft crinkling sound playing from between them. "I was hoping to show you my progress on potions?"
