Twilight Sparkle turns herself into a diaper, and is worn by Troubleshoes.

Twilight Sparkle becomes a diaper (Twiaper), and puts herself on Troubleshoes. Well, it's obvious what happens next.

Contains diaper fetish, scat, pee, teats leaking a mix of those things, and a couple good ole wholesome orgasms.

The ideas for Troubleshoes as the second character and for the crotchboobs leaking unspeakable fluids were both entirely Majin Syeekoh's fault. The rest is basically all me.

If this is your fetish, then, uh... enjoy. If not, feel free to smash that dislike button and give me a good ole "What the fuck is this?" in the comments. That way, everybody wins.

Why would someone write this? lmao

Twilight Sparkle closed her eyes and concentrated, letting power gather at the base of her horn. In her mind, she assembled a spell, component by component, until it was complete. She let it go then, feeling the magic running up through her horn where it was channeled and directed... right back at herself.

Once fully unleashed, the spell surrounded her with her normal raspberry aura. Her wings and hooves retracted slowly inside her body, leaving her lying helpless on the floor. Her neck shortened and disappeared as her head melded with her torso, and her mane shrank and disappeared completely inside her beanlike body. An indent appeared in the middle of her back, and it deepened quickly, cutting a neat hole through her that split into two directions, making two other holes in her sides. The holes widened until she was mostly hollow, and the new inside of her became soft and absorbent. Her outside pony hair melted together and became a crinkly waterproof layer.

At the end, she was on the floor, face up and unable to move any part of herself. Her horn still functioned, so she grabbed herself with her telekinesis, and easily floated up to look at herself in a mirror. She could see her new diaper form, her face and horn in front, and her tail hanging down from where it stuck out in the back. Her ears didn't exist, but she could still hear just fine, and the subtle crinkling as she moved made her excited.

"Okay, Troubleshoes, come on in," Twiaper said.

The door opened and in stepped a rather large pony, anxious but excited to get started.

"W-wow, Twilight," he said, "you look amazing."

"Thanks. And call me Twiaper," she replied with a smirk.

"Haha... o-okay. Can I put you on now?" he asked. His member was already firm, betraying his eagerness to begin.

"Yep. Let me help you out," Twiaper said, floating herself behind him.

Twiaper positioned herself low to the floor and opened herself up to give him space to step into her. The clumsy oaf kicked her instead, dazing her for a second.

"Oops!" he cried. "Sorry!"

Twiaper shook herself and smiled. "It's okay, Troubleshoes, it happens. Let's try again."

She returned to the same position and opened herself up again, but this time when Troubleshoes lifted a leg, she swiftly flew up, trapping it before it could do unintended harm.

"Okay, other leg," Twiaper said.

Troubleshoes repeated the same action, lifting his other leg, and Twiaper quickly stretched herself around it. Successfully on, she pulled herself up until she comfortably enveloped his ass and crotch. His stallionhood, quite large just as he himself was, took some stretching to fit inside herself. Her face, being on that side of him, bulged outward, and she smiled at the feeling of pony cock stretching her face like that. It was a unique experience to feel like a living, throbbing rod of flesh was inside her head and pushing at her face from behind.

The diaper blushed.

"Okay, Troubleshoes. Feel free to, um... you know. Whenever." Twiaper closed her eyes as the cock twitched again, and she could feel his quickening heartbeat through the throbs of his dick.

"O-okay, Twiaper. I'm ready."

Troubleshoes took a deep breath and let it out slowly. He relaxed himself, and a trickle of urine came from the tip of his penis. Twiaper could feel her absorbent inside collecting it. The large stallion let a satisfied hum escape him as he yellowed her interior with his hot waste fluid. Twiaper felt warm, and not just because of the heat filling her, but arousal that she could not satisfy, as her diaper form had no genitals to rub at or satisfy.

"Mmm, yes, Troubleshoes! Fill me up!" Twiaper said with a horny whimper.

He grunted as a small eruption of gas came from his puckered ponut. It widened to allow a steamy log of feces to slide into Twiaper, where it was smushed against her and his ass, and it deformed into sticky mush. If Twiaper could, she would have orgasmed. Instead, she vocalized her enjoyment.

"Ohh, fuck yes, that feels so good!" she cried.

Troubleshoes rocked his hips as more poop found freedom from his bowels, only to be trapped in the cushy confines of Twiaper's soft padding. His cock suddenly flared, and he shot a mix of urine and semen into the back of her face, moaning in pleasure as he did.

"Oh, Twiaper," he said as his orgasm tapered off. "That was... the best feeling ever."

"Y-yeah..." Twiaper said, panting. Fortunately, the smell was mostly contained within her, and did not reach her nostrils. "I think I should transform back now."

Troubleshoes nodded, and Twiaper removed herself from his ass, which was now sticky with semen, pee, and poop. After a few seconds of concentration, Twiaper released her reversal spell. The holes in her closed up, and her body grew as her normal pony parts were replaced. She regrew her neck, legs, and wings, and soon found herself standing again, back to her normal pony self.

"Ah, there we go," Twilight said. "Hmm, something feels different."

"Were your teats always so... big?" Troubleshoes asked.

"Huh?" Twilight leaned her head down and took an upside-down look between her legs. Her teats were like blown-up party balloons! "What??"

Before panic could set in, she saw them dripping a murky light brown liquid.

"Oh, whew," she said, relieved. "It's just your... deposit. Here, I'll get it out."

Using her magic, Twilight squeezed her teat, and it squirted out a steady stream of shitty piss onto the floor. The occasional chunk would get stuck, but otherwise it all seemed to be coming out fairly easily. Troubleshoes watched with curiosity, but said nothing.

By the time the first teat was empty, Twilight was panting, and her marehood was winking. She began casually rubbing at her clit as she emptied the second teat. The thin yellowish brown spray splattered messily onto the floor, making a light splashing sound that was almost playful to the ears, like a hundred tiny triangles being played for the song of Twilight's soft moans. Her hoof pressed against her slick marehood, and she came just as the teat emptied, the last few spurts coming out in sync with her convulsing inner walls that spilled droplets of marecum to the floor.

As the last few drips of Troubleshoes' mess dripped onto her floor, she was left panting.

"Whew... that was fantastic, Troubleshoes," Twilight said. "Let's do this again some time."

The large earth pony nodded. "I'd like that. For now, I think I need a bath."

"Haha, yeah," Twilight laughed as she eyed his shitty ass, "I think we both do. Let's head into my private bathroom, shall we?" She winked in more ways than one, and walked toward the door to her bathroom.

"Shouldn't we... you know... clean this up?" Troubleshoes asked.

"Nah, I'll make Spike do it."

Twilight laughed. Troubleshoes smirked, and soon joined in the merriment. The two messy ponies disappeared behind the bathroom door.

They had sex during their bath.
