"Phew...that was a good training session. Gotta say, you're a tough opponent for someone without actual ARMS."
Ribbon Girl smiled and laughed a little as she complimented Mechanica on her technique during the sparring match. At least, she intended it to be a compliment. But as she looked at the younger girl's expression, she wasn't sure if it came across that way.
"Umm...y-yeah, sure. Umm...you...you pack quite a punch, too, Ribbon Girl. Hehe..."
"Oh no! Did I say something wrong? I...I didn't mean to..."
Mechanica quickly looked up and tried her best to calm her idol down.
"Oh nonono! Don't worry! I...I appreciate it. I'm just...not feeling too well..."
"Oh dear! Do you want me to stay with..."
"NO!"
The pop star was a little taken aback by Mechanica's sudden loud exclamation, and the young mech pilot's face turned bright red.
"I...I mean...please don't...worry about me, okay? Just...go home. My dad will be here soon to pick me up."
She smiled in the hopes of getting Ribbon Girl out of her hair.
"Umm...sure...I'll be on my way then..."
She made her way out of the training hall, still a bit confused about Mechanica's behavior. Then again, maybe she was just nervous? It wasn't the first time the two trained together, but it must still be pretty exciting to suddenly be so close to your idol. Especially since today, nobody else was sparring, so it was the first time the two of them were completely alone in the ARMS League Training Facilities.
"Yeah, that must be it. I'm sure she...oh! Silly me!"
She looked at her hands and noticed that she was still wearing her ARMS, the Sparky on the left and the Slapamander on her right hand. They were property of the ARMS League and supposed to be stored in the Training Facilities' storage room, which is also where the League allowed Mechanica to store her robot suit. Ribbon Girl turned and made her way to the storage room.
"I just hope she doesn't think I came back to spy on her or something..."
As she approached the door, she could see that it was open a bit and could hear sounds she assumed were Mechanica getting her mech into place and exiting said mech. As she was just about to open the door, she could also smell a strange odour.
"Hey Mechanica. Sorry, I just forgot to..."
"NO!"
The pink-clad fighter audibly gasped when she saw her sparring partner stand in front of the yellow machine, wearing nothing but a yellow and black shirt...and a diaper!
An obviously used diaper.
"I...I...I can explain! I...I'm just...it's an experiment and...you know, my actual pants are...this isn't really..."
The poor girl was blushing heavily and almost crying. And maybe it was that crying in combination with the full diaper that triggered something in Ribbon Girl and led her to do what she did next.
Mechanica went silent the moment she felt Ribbon Girl hug her tightly.
"There, there. It's okay. I don't judge you, I won't laugh at you, and I won't tell anybody else. Now, why don't you tell me why you're wearing that thing?"
Mechanica was still blushing immensely, but the hug and Ribbon Girl's calm, almost motherly tone helped her calm down a bit. She didn't even fully realize what was happening as she started to explain, still sobbing a little.
"I...I don't know...dad says I was just born that way and there's nothing we can do. We tried a lot of different medicines and therapy, but I just can't..."
"...make it to the potty in time?"
Mechanica was embarrassed that Ribbon Girl used such a childish word when talking to her, but when she looked at her face, she saw a smile that seemed genuine and caring.
Then, something unpleasant entered her nose.
"I...I'm sorry about the smell..."
Ribbon Girl giggled.
"It's okay. I used to babysit every now and then, before the popstar and ARMS fighter thing. I changed a loooot of dirty diapers, so changing yours shouldn't be too hard."
Mechanica's ears perked up at that.
"What did you just say?"
Now it was time for Ribbon Girl's face to take on a color similar to her trademark outfit.
"I-I'm sorry, I...I guess I just remembered how much I loved babysitting, and taking care of those kids, and even changing their diapers was kinda cute and...and I guess my brain just hoped that..."
CHUNK.
A compartment opened on the front of Mechanica's mech and from that compartment, she took a pack of diapers, baby wipes, a bottle of baby powder and a changing mat, which she spread out on the floor and proceded to place herself upon. Blushing again, she said:
"Y-you can start...if you want...b-but make it quick, my dad's gonna be here any minute!"
The Airess was visibly surprised, but quickly took on that motherly smile again, as she kneeled down and started opening up her friend's used diaper.
"Phew, someone's a smelly baby, huh?"
Mechanica blushed even more, but also couldn't help but smile as Ribbon Girl started expertly cleaning her diaper area, balling up the used diaper, and powdering her privates.
"Now lift your bum!"
Mechanica did as she was told, as Ribbon Girl took a fresh diaper from the package and slid it underneath her. After two quick motions, the new diaper was sealed and Ribbon Girl patted the front and smiled.
"There! All done!"
Mechanica slowly got up and mumbled a shy "thank you" as she packed up the changing utensils and put them back in her mech.
"What are you gonna do with the used one?" Ribbon Girl asked her.
CHUNK.
Another compartment, on the backside this time, opened up and Mechanica threw the smelly object inside.
"Bio-fuel! What did you think how I kept this thing going?"
"Finding a way to make the best out of the situation. Classic Mechanica."
They both laughed when they heard a voice from outside call out Mechanica's name.
"Oh, that's my dad! I...I better go...and...thank you again."
"N-no problem...hey, how about...you and I...have a little sleepover this weekend?"
The brunette's eyes grew wide.
"R-really?"
"Yeah. It'll be fun. Just..."
Ribbon Girl put her mouth next to Mechanica's ear and whispered:
"...bring enough diapers, okay?"
Ribbon Girl winked. Mechanica blushed.
"S-sure...I-I-I gotta go...s-see you later..."
"Yeah, see you later...you cute little baby you..."
Still blushing, Mechanica left the storage room and went to where her dad was waiting for her.
She couldn't wait for the weekend.
