Slime Wash

Tria had a thought. She didn't want to be all dirty when Spirit-sama summoned her.

But making Spirit-sama wait while she freshened up was absolutely out of the question.

In other words, wouldn't it be wonderful if there was a way to clean herself in seconds?

"And so, Tria came up with an idea. If sticking her hand into Miitei was enough to wash it, couldn't she do laundry and take baths that way too?"

"I'll do it if you call me Onee-chan?"

"…"

"…"

"Let's give it a try, Mii-nee."

"Yeah! Onee-chan will do it for you!"

And that was how it happened.

"Sooo, what does Onee-chan need to do?"

"Ideally, I wouldn't even need to take my clothes off, just one quick go and my whole body is clean. I want Miite… Mii-nee to swallow me up whole, clean me off, and spit me out."

"Okaaay, leave it to me! Ahhhn～"

No sooner said than done, Miitei opened wide and engulfed Tria. It was more of a body tackle than anything, which made Tria wonder "Did she really need to open her mouth?" but it was probably a mental thing.

She closed her eyes and held her breath. A squirmy, licking-all-over sensation enveloped her entire body, and then she was spat back out.

"Oopsie, sorry. Some of me got stuck inside your clothes."

"I'm all slimy."

Failure. Well, Tria hadn't expected it to work on the first try.

"My face, hands, and feet feel squeaky clean though, so it's just a matter of practice?"

"Hmm, your boobs and your down-there were kinda slippery? Like I couldn't really touch them?"

"Hm?"

Sure enough, residual Slime had gotten inside her clothing, but only around her stomach and back.

Anywhere that would be covered by underwear, it seemed, was off-limits to Miitei.

"… Hmm. So I have to change my own underwear then."

"Is that so? Rather than Spirit-sama protecting those spots or something?"

"Hm? If that's the case, wouldn't it actually mean I shouldn't change what Miitei can't touch on my own?"

"I know what that's called! It's, um, maniac! Wait, was it abnormal? Something like that!"

"Wow. You're surprisingly knowledgeable, Miitei."

"'Cause I'm the big sis! … Hey, call me Mii-nee properly! Otherwise I won't pick up my Slime bits!"

"Oops. Please, Mii-nee."

"Leave it to Onee-chan!"

Miitei collected the residual Slime from her clothes… Yep, even the areas where the Slime had been collected felt refreshed.

The question was how to deal with the areas that blocked outside contact.

"Come to think of it, Alto's Spirit-sama mentioned that combat actions can bypass it. Maybe something like a little prick?"

"Hmm, think it'd work? Wanna try?"

"Please."

"Please, Onee-chan, right?"

"… Do I have to say that every time?"

"Yes!"

"Please, Mii-nee."

"Okay～! Ahhhn～"

Miitei swallowed Tria for the second time. STAB!! CRUNCH!!

"HGYABGLRB!?"

"Oh, sorry, was that a bit too hard? Ptoo."

"Pbah, hah, hah… F-First Aid… uuu…"

Placing her hands on herself, she used her healing skill to recover. Her whole body felt squeaky clean, but that had really hurt.

Also, this time there was no Slime residue left inside her clothes. If she could ignore the pain, it was technically a success.

"I said just a little prick…"

"I-It's hard to control! I'm sorryyy."

"Sniff. From now on, I'm going back to calling you Miitei."

"I said I'm sorryyy!"

"Sniff."

And just like that, she deftly dropped the "nee" and reverted to the original name.

Always turning a fall into an opportunity. Smart girl.

"We've confirmed that attacks can bypass it. This is progress…"

"But if I hold back too much, I probably can't touch those spots at all."

"… So it's a trade-off between pain and time, huh… What if you attacked somewhere that doesn't hurt much while cleaning?"

"Hmm. Like, patting your butt while I do it?"

"Yeah. Do it, Miitei."

"Onee-chan…"

"Do it, Miitei."

With a sulky "Muu," Miitei puffed out her cheeks, then opened wide for a third "Ahhhn～"

Pat-pat-munch-munch-pat-pat-munch-munch, ptoo!

"…"

"…"

"Success! Underwear and everything underneath, squeaky clean! My butt stings a little, but that's totally bearable!"

"Yaaay, Tria-chan!"

"Yeaaah!" The two celebrated with a high-five.

"I should tell Alto and Penpen about this. And Gin and Nika too. Everyone will be thrilled!"

"Huh? But I don't wanna do it for anyone who isn't my little sister."

"…"

"I'm the Onee-chan, you know! I'll happily gobble up my little sister's dirty bits, but someone who's not my sister? No way!"

"Hmm…!"

She had a point. This was asking Miitei to eat grime and dead skin. She couldn't exactly force her.

"If they're my little sister, sure? Right? Right?"

"Mmm. Can't be helped. Hm? Wait, doesn't that actually mean the reverse? That this is Tria-exclusive?"

"I'll do it if they call themselves my little sister before every use? Oh, but not Penpen. She's not a little sister, she's Mama."

"So it's Tria-exclusive. Can't be helped. I feel bad being the only one who's always spotless, but it can't be helped. Heheh, that works just fine, actually."

And so Tria gained the ability to clean herself in seconds via Miitei-Style Instant Wash. With Miitei by her side, even a surprise summon meant she could present herself to Spirit-sama looking her very best.

Alto and the others would just have to do their best rushing to the shower.
