Ritsu slowly walked to the dress rack, trying to find the least embarrassing outfit. She didn't realize that one was missing for Azusa. Her mind was elsewhere at the moment. The one that was least embarrassing to her was a light blue dress with white clouds spread across it.
Miss Yamanaka spoke up "Oooo, I guested right. I thought you'd pick that one."
Yui was also cheering. Ritsu ignored both of them, walking to the room exit with an annoyed expression. She was sorta hunched over "Let's just get this over with."
She had got herself in a trap by agreeing to these terms before hand. Perhaps, taking that risky deal wasn't the best idea. She walked to the bathroom without really paying attention to Miss Yamanaka. She walked into the bathroom completely and soon realized... Miss Yamanaka was in there too.
Suddenly, her brain started working and she spoke up "WAIT A MINUTE! WHAT ARE YOU DOING IN HERE?!"
Miss Yamanaka took a different approach with Ritsu. Scare tactics or relate-ability wouldn't work on her. In a kind voice, she said "I came in dear to give you a diaper change and don't you think about yelling again. If you do, people will come upstairs and I'll tell them that I'm helping you in the bathroom."
Ritsu was terrorized at that possibility, shaking in fear. This teacher just duped her. She could try to test her teacher. But her teacher had a determined look. Plus, she already failed at guessing what would happen with Yui. Her odds were zilch. This was gonna happen, and there wasn't much she could do.
Miss Yamanaka let the reality hit her for a bit and then she started patting her back. "It's okay. I laid a mat here for you in advance. This will be fun."
With a sad expression, Ritsu laid on the mat, taking deep breaths. She was thinking to herself "okay, let's just get this over with lady."
Miss Yamanaka just smiled "Good girl. Now, let's get situated. I assume you laid down without taking off your clothes, because you want me to undress you and diaper change you. That's alright with me. This will be extremely fun."
This reality just hit her even harder. Great, her quickness to get this over with led to this. What more, she didn't really have the resolve to challenge Miss Yamanaka. She just laid there and let reality have its way with her. All things considered, Miss Yamanaka was really good at this. Ritsu's socks and shoes were off within seconds. She then lifted up Ritsu's legs, gently removing her panties. Then she unbuttoned Ritsu's uniforms, propped her back up, and removed the clothing, leaving Ritsu naked with just her bra.
Miss Yamanaka then held Ritsu's legs again and powerfully applied baby powder. She finished the rest of the changing quickly, putting the diaper underneath and strapping it in place. The energy and speed she put into the diaper changing itself mirrored Ritsu's drum playing. Lastly, Miss Yamanaka stood Ritsu up and put on the light blue dress. Ritsu looked at her reflection in the mirror. She was dumbfounded. Everything she was wearing was so childish, so babylike. She really wanted to cry, but something hit her... literally. Miss Yamanaka had noticed her displeasure, and pat the backside of Ritsu's Diaper. Ritsu felt something oddly nice for a brief second. Ritsu spoke up for once, pretty confidently "What was that?"
"Why that? That was just me hitting your diaper. You may have felt the diaper press harder for a second there. Sorry I hit you. It's just-"
Ritsu cut her off. "Wait a minute lady. I need to see something."
Miss Yamanaka just smiled, predicting Ritsu's next response. Ritsu sat on the toilet seat and quickly said "Awwwwww... that feels nice."
Miss Yamanaka was overcome with joy at the sight of Ritsu liking the diaper. She then hugged Ritsu. Ritsu's reaction to the hug was similar "AHhhhhh, that feels even nicer! What is this dress made out of?"
"It's baby wool. Super soft for the sensitive skin of a baby."
Ritsu started pressing the dress up against her. "AHhhhhh that would explain it. I could totally play drums in this stuff. It's soo warm."
Miss Yamanaka then grabbed Ritsu's hands, showing her to the mirror again. "What do you think of the look though?"
"It looks... it looks adorable. I look adorable in it. Admittedly though, this is pretty embarrassing to wear."
Her adviser spoke up "But does their point of view really matter. You've worn a lot of things Mio thought were embarrassing."
"Hahaha, good point." This was the first time Ritsu smiled since seeing herself in the mirror. "Ya know... it doesn't look half bad. A little bulgy all around, but they'll never see that. I kinda dig this now that I really think about it." Ritsu then hugged Miss Yamanaka "Thanks for making it Miss Yamanaka. Sorry I judged it too soon. That's Mio's job, not mine."
"It's completely alright. But will you be alright in there though?"
"Ahh.. yeah. Eh, Mio will be wearing this soon anyways and I can take pictures of her if she takes pictures of me. Plus, I got so many more pictures of her anyhow. I'm probably good. Plus, this gives me and Yui some time to play together, since wardrobes taking up so much time today."
"I'm glad you're feeling alright. Now, let's head back."
"K. sounds good."
Miss Yamanaka left the mat in like before. This was going by better than she expected. Ritsu was going to be one of the hardest, and that work was already over.
Ritsu and Yamanaka came into the band room. Unlike Yui's entrance, Ritsu came in first. Once the door was closed, Ritsu kinda announced herself with a proud gesture "And the adorable Ritsu is here at last!"
Yui quickly ran up to her "D'awwww. You look adorable! I told you this was fun."
"Yah, yea.. you were right. You look adorable too. Let's goof off. This is gonna likely take up a lot of club time anyway."
Yui smiled "YAY! I can't wait!"
Before they continued, Ritsu told Mugi "Hey Mugi, you totally should go next, since Mio over there is still freaking. And Trust me! It is more fun wearing this than it looks!"
The two of them started playing around the couch. Meanwhile, Mugi nervously stood up, moving to the clothes dresser.
