Chapter 1

“Ahh, the circus!” Lucy sighed, walking lazily in between stalls with Wendy “Nice that we got a day off.”

“Yep!” Wendy agreed “I just hope that the others don’t get us into too much trouble. Those games don’t stand a chance against Erza!”

“Hey you two!” 

The girls looked over to a nearby tent where a girl clown was gesturing for them to come inside. Lucy looked at Wendy and shrugged. They walked inside.

“Want to play a game to win a prize? It’s free!” *Giggle* The clown girl giggled

“What’s the game?” Wendy asked

“It’s simple.” The clown girl giggled. She gestured at some stools surrounding a table with pies on it “You just need to finish a pie before the time runs out!”

“Oh, okay.” Lucy said. That seemed pretty easy, the pies were only a couple inches. They could get free food and a prize at the same time!

“Sure.” Wendy shrugged. The two girls sat on the stools in front of pies.

“Ready, set, go!” 

Wendy picked up her fork and took a bite. Her eyes widened. The pie was crazy rich! But she wasn’t going to lose. She forced herself to keep eating, even while it felt like the calories were going straight to her butt. Her panties even felt like they were getting tighter. But that wasn’t possible, was it?

“Is my butt getting big?” Wendy asked Lucy

“Yep!” Lucy said. Already the two girl’s butts were so round and plump that they were hanging off the chairs. Their panties stretched thin from trying to contain their expanding cheeks. Snap! Snap! It became too much and their panties snapped.

*Giggle* “Oopsie!” Lucy giggled playfully. She kept eating, wolfing down the rest of her pie. Wendy stopped.

“Um, what kind of pie is this?” Wendy asked, not so sure that she wanted to win anymore

“Bubblebutt berry!” *Giggle* The clown girl giggled

“It’s, uh, rich…” Wendy commented

“Yep, but don’t worry! All the fat goes straight to your bottom. Well, and your boobies!”

Snap! Lucy’s bra snapped as her breasts swelled. Riiip! Her shirt couldn’t contain her bust.

“Mmm, yummy!” Lucy giggled, admiring her naked chest. She looked at Wendy “You haven’t finished yet!”

“Lucy I’m not sure- mmm!”

Lucy seized the fork and shoveled more pie into Wendy’s mouth “Silly Wendy, good girls always eat their dessert!” *Giggle* *Giggle*

“Mmm-mmmph?” Wendy asked. Snap! Tear! Her shirt tore open too.

“Congratulations, you two win!” The clown girl giggled

“Yay!” Lucy bounced. Her butt and breasts jiggled with every little movement she made. She giggled and slapped at her butt cheeks. She felt so silly and happy all of a sudden!

“Um, do you have any clothes?” Wendy asked, feeling her breasts. She was a little more aware of her nudity than Lucy.

“Oh sure!” The clown girl said “That’s what your prize is!”

“Clothes?” Wendy asked

“Yep! And diapers!” 

The clown girl held up a package of thick, disposable diapers. On the front was a giggling clown girl. She looked rather dumb. In her other hand she held up some rainbow colored baby dresses.

“We’re not babies!” Wendy said automatically

“Of course you aren’t! Now let’s get you two bubblebutts into diapers before you have accidents on the floor!”

“Come on Wendy, it’ll be fun!” Lucy said, cheerfully taking a diaper and taping it on herself and then pulling a dress over her head. She giggled and admired herself “Aww, I look so cute!”

“How does it even fit over your butt?” Wendy wondered aloud. The diaper was huge, bigger than any panties she had ever seen. 

*Giggle* “Come on, you wear a diaper too!” Lucy said and Wendy found herself being helped into a dress and diaper. She patted her rear experimentally. Crinkle! Crinkle! The diaper was so thick that it was pushing her legs apart.

“It’s… crinkly. And really thick.” She commented “Um, you don’t actually expect us to use them do you?”

“Only if you girls don’t make it to the potty in time.” The clown girl said

Wendy laughed “Oh, okay.”

Gurgle! It was just then that both girl’s stomachs gurgled and suddenly they were pushing their knees together doing the potty dance in desperation. They had gotten absolutely no warning.

“P-Potty!” stuttered Lucy. Blort! She had a wet fart in her diaper.

“Sure, right in here.” The clown girl pulled back a curtain. There was a lone training potty illuminated in the middle of a big, dark room. Neither Wendy nor Lucy questioned it, they just needed to relieve themselves. They made a mad dash for the potty.

“Stop shoving! I want to use the potty!” Wendy said, pushing at Lucy

“No! I need to go too!” Lucy said

Splat! A pie came out of nowhere and hit Wendy dead on in the face. She staggered backwards, momentarily blinded. Lucy grinned and sat on the training potty triumphantly, still wearing her diaper. Splooort! She relieved herself into her padding.

“I did a poopy on the potty!” She announced proudly just before Splat! A pie hit her in the face, knocking her backwards off the training potty.

Meanwhile Wendy had wiped the pie off her face. Something was off though. Her face was covered in white makeup with red spots on each cheek. Her nose had been replaced by a bright red ball. Her hair was tied up like an ice cream swirl on top of her head. And her expression, she was smiling and giggling airily even while she picked herself up off the ground.

“My turn to use the potty!” She said, running and sitting down. She didn’t take her diaper off either. Faart! Splort! She stood up, her messy diaper sagging in between her legs.

“Hey, who’s throwing pies? I love pies!” Lucy said, wiping her face clean. She had makeup and a red nose too. Her hair tied itself into golden curly pigtails.

It was only then that Wendy and Lucy became aware of the laughter all around them. They stood up and looked around for the first time. They were in the middle of a circus ring, with several spotlights shining on them. The stands around them were packed with people laughing hysterically at the sight. Lucy scratched her head in confusion.

“Wendy did you know we had a show now?”

“Nope! I just thought this was where the potty was.”

The audience laughed harder. They thought it was all an act.

“Should we change our diapers now?” Wendy wondered aloud

“No way! We’ve got to do our show!” Lucy said

“And you want to wear your messy diaper.” Wendy added

*Giggle* “Maybe…” Lucy admitted “But you like wearing messy diapers too!”

“I do not! I’m not a baby!” Wendy retorted

“You do too!” Lucy grabbed a handful of Wendy’s saggy padding and squeezed. Crinkle! Squelch! Smush! Wendy let out an involuntary giggle. *Giggle*

“Stop it!” She said, but it was playful now. She smooched Lucy’s face and her eyes widened. She licked Lucy’s cheek.

“Does my face taste good?” Lucy giggled

“It tastes like vanilla ice cream!” Wendy exclaimed

“Really?” Lucy licked Wendy’s face “Mmm, blueberry pie!”

“Hee hee!” Wendy giggled. She brought her hand down to Lucy’s diaper and felt her. Mush!

*Giggle* “I’ll mush your diapie if you mush mine!” She said

“Yay!” Lucy said, happily moving her hands to Wendy’s diaper. Mush! Squish! Smush! Honk! Her eyes widened.

“What was that?”

“Your tushie! It honked!” Wendy exclaimed, squeezing Lucy’s butt a little harder. Honk! Honk! 

“Really?” Lucy asked. She squeezed Wendy’s butt. Honk!

*Giggle* “Appropriate for a little clown girl!” Wendy commented. She honked Lucy’s nose playfully. Honk! Braap! Lucy grunted and she made a mess in her already full diaper.

“I think you made me do a poopy!” *Giggle* She said. Wendy honked her own nose. Honk! Blort! Her diaper sagged lower between her knees.

“Yep! That makes you go poopy in your diapie!” She agreed. Splort!

A light came on across the stage, illuminating an oversize, oddly shaped wrapped present. It was moving.

“Oooh, a present! Let’s see what it is!” Lucy said, toddling in her diaper. Crinkle! Crinkle! Squish! She tore at the wrapping revealing Cana, bound and gagged on her knees. She looked at Lucy in wide eyed surprise.

“Mmmm!” She said

“Cana! Great to see you here!” Wendy said. She removed the gag. Cana gasped

“Wendy! Lucy! There’s something wrong with this circus! They put something in the rum I ordered that made me all woozy and tied me up!”

“Why aren’t you wearing a diaper?” Wendy asked

Cana looked at her “Um, maybe because I’m not a dumb baby? Why are you two in diapers anyways? And what’s that smell?”

“Poopy!” Lucy giggled

“Poopy? Eww, don’t tell me… You actually used them!?!”
