Mio turned to the dress rack and only saw one dress. "Hey! How come I don't get to pick mine?"
Miss Yamanaka quickly perked up. "Sorry about that Mio. I-I only brought four, because Azusa said she'd probably not come. I can't make a dozen of these things."
Mio sighed "Augh, that makes sense."
Mio's friends surrounded her, giving her their commentary.
Ritsu said "Come on Mio! That dress will look pretty good on you!"
Yui agreed "Ritsu's right Mio. This dress is totally awesome for you."
"I agree" Mugi responded.
Mio pulled it from the rack to get a better look. It was a lavender dress with dark purple flowers. The colors spoke to her, but she didn't want to give away her thoughts. She pulled it out. "Yeah, it's a nice dress. Let's get this over with."
The others were surprised she didn't like it. But Miss Yamanaka could tell Mio was lying. There was something in Mio's expression as she walked out that showed this.
Miss Yamanaka walked Mio to the bathroom. As they were outside, Mio said "This is enough. I'll handle the rest."
"K, everything's inside for you."
Mio nodded "Thank you, I guess." She walked in and quickly saw the mat. Her curiosity was spiked. To top it off, there were no diapers in here. "Hey Miss Yamanaka, what's going on? There's a mat and-"
Miss Yamanaka cut her off, saying "Oh yes. That one sec!" She also bolted into the bathroom, closing the door.
Mio was suspicious of Miss Yamanaka, but in the heat of the moment, she couldn't do anything. After being cut off, she didn't know what to do.
"You wanted to know where the diapers were? I realized they weren't inside."
"Then why did you come in? You could have just handed them to me out there."
"What? In the open? What if someone saw them? You'd be embarrassed"
"But we're far from any classes. It wouldn't have been that bad. Also, what's with this mat. Come to think of it.. it looks like a baby mat."
Miss Yamanaka was frustrated. It wasn't long and Mio was going to guess everything. All she could do now is get in between the door and Mio. So, that's what she did.
"Why would you need a baby mat? Wait.. No. Come on. Please don't tell me..."
Miss Yamanaka responded quickly "It's for your diaper change. Yes."
Mio protested in an emotional outburst "I-I can't. I won't!" Then she sat on the toilet.
This wouldn't do. Miss Yamanaka's only hope was to break her resolve. "Why not?"
"Because I'm not a BABY!"
Miss Yamanaka towered over her. "SO?! This is an outfit for having fun! You don't have to be a baby."
"But you said it yourself that the dresses represent youth and babyhood."
"Wha.. What about your friends then? They are wearing them and they're fine. Ritsu's loving hers. Are you insulting your friends?"
"No, they just.. I don't know why they agreed. And Ritsu's just not thinking straight. It's not meant as an insult."
"Mio, your friends let me give each of them a diaper change. Why not you?"
Mio thought to herself "Really? What did she do to convince them?"
Miss Yamanaka spoke up again. "You know I think I know why you won't do it."
"Why?"
"Because you're afraid of being a baby again, or even treated like one. You're scared now. I bet you were more frightened as baby. That's why you're doing this. You're afraid Ritsu will frighten you even more with this outfit on."
Her words hurt hard. Mio started to cry, but tried to hesitate.
"Why are you hesitating Mio? Cry. Let your youth shine!"
Mio didn't know what went over her, but she did as instructed, letting out all the tears she could. While crying, she stopped paying attention to her surroundings. Miss Yamanaka got her opening then.
While Mio cried, Yamanaka removed Mio's uniform, both the shirt and skirt, followed by Mio's panties. Then she laid Mio on the mat and removed her socks and shoes. There, Mio was completely naked except for her bra. On the ground, Mio's cries blurred her vision. The shining bathroom lights didn't help either. Meanwhile, Miss Yamanaka lifted Mio's legs and proceeded as quickly as she could with the changing. She applied the powder, slid a diaper underneath, and strapped the diaper in place. After completing it, Yamanaka took a deep breath. The heavy lifting was over.
She helped Mio onto her feet and said. "There there. I just finished your diaper change." Then she rubbed Mio's back.
Mio stared at herself in the mirror and started to cry harder. "Noo.. you had to change me?!"
It wasn't working though. The girl still had cries in her. Miss Yamanaka was lost on what to do, and then the idea hit her. "Give her a pacifier. The soothes babies' cries."
All of sudden, something interrupted her cries. Her cries oddly stopped. Mio looked down to see the culprit. It was just a purple loop. Then she looked in the mirror and freaked. She thought "A PACIFIER!" Then she realized she wasn't crying and thought to herself "Why aren't I crying more? Do I like the pacifier? If I like the pacifier, then.. then a part of me is a baby."
Miss Yamanaka saw the panic in Mio's eyes and comforted her. "It's alright Mio. Pacifiers are meant to do this. They're suppose to calm you. I recommend you keep that pacifier in and you'll never cry. You'll overcome you're fears somewhat with it. Plus, it goes great with your outfit. Speaking of which! Be still!"
Miss Yamanaka then put the purple dress over Mio, and the costume was completely on.
"You look adorable!!!"
Mio was shy, and pulled out the pacifier for only a second "Can I use this pacifier for a bit?"
"Use it to your hearts content darling."
Mio nodded and then followed Miss Yamanaka to the room. Miss Yamanaka opened the room first, giving an announcement "The bassist of the Light Music Club! Mio!"
Ritsu, Yui, and Mugi all waited with suspense. Mio didn't want to come. So, Miss Yamanaka yanked her in. "Here she is. Wearing her purple dress and diaper."
Yui and Mugi complimented her and Mio only nodded in response.
Ritsu on the other hand was surprised she came in with a pacifier. She laughed in response "Don't forget her purple pacifier Miss Yamanaka."
"Ah, yes that. Thanks Ritsu."
Yui and Mugi became curious about that too, but the three were even more surprised that Mio didn't react. Ritsu asked "What gives? Why aren't you freaking out as usual?"
Mio closed her eyes for a second, reopened them and pulled out the pacifier for a brief moment. "I didn't react, because this pacifier helps me control my emotions." She quickly put the pacifier back in.
Ritsu hammered "So that's it... Could you give me that pacifier real quick? I wanna try." (Obviously, she just wanted to mess with Mio)
However, Miss Yamanaka didn't give the right response. "No need to take hers. You each have your own. Here you all go." She gave out the pacifiers, which was pretty frustrating for Ritsu. Now, she had to actually try this thing.
To her and the rest surprise, these pacifiers were a lot of fun. Ritsu and Yui loved the feel of the pacifier, even if Ritsu wouldn't admit it. Mugi just liked the pacifier, because it made her feel like one of the group. Additionally, it made her feel more innocent.
A couple minutes passed by and the four of them were in their normal seats, wearing baby dresses, diapers, and sucking on pacifiers.
It was beginning to get awkward, so Miss Yamanaka left some instructions and left. "Girls, remember those costumes are just costumes. Still, if you enjoy the roleplay, I have tons of baby things in that suitcase. I also have plenty of diapers, in case anyone of you makes a messy wessy." The girls blushed and looked at each other. Then Mio removed her pacifier and said "We're good. Thanks Miss Yamanaka. We'll behave."
Miss Yamanaka left and about 30 minutes passed before Azusa entered the room.
