Chapter 40

Fortieth Episode

I grab Uzuki-chan’s diaper and slowly drag it down.

“Ah”

Shizuki raised a small voice just as the diaper was making it past the crotch area. And at once Uzuki-chan’s face goes crimson red and tears start to accumulate on her eyes.

“Mas-“

She must be trying to stop me. I turn to look at Shizuki who is trying to stop me and shake my head at her.

The fact that Uzuki-chan’s face turned red when she noticed that I took off her diaper is proof that she cares about having peed herself.

Even if she is exposing her breasts without a bit of shame, it seems that she cares a lot about being able to go to the toilet by herself.

“It’s alright Uzuki-chan, you can already use the toilet by yourself”

I smile and talk gently to Uzuki-chan as I stare into her eyes.

“U-chan, will do her best”

Uzuki-chan mutters with a trembling voice.

It wasn’t just the pee in the diaper that Uzuki-chan is concerned about.

She also minds that place.

The fact that she worries about that is enough proof that she understands her situation.

Uzuki-chan lifts her feet herself so that I can take off the diaper. Then, holding up the back of her thigh, I wipe her butt.

Although because of that, her faint pink lips and ass crack are in full view.

“Thank you, Uzuki-chan”

An absurdly beautiful girl that looks like Shizuki but with gray hair and blue eyes. It’s quite a view to have such a beauty expose her shameful parts. If it was another situation it would be enough to fuel my libido, but unexpectedly this wasn’t the case.

“Master…”

Shizuki watches me anxiously and hands me a wet tissue.

“Oh, thank you”

I thank Shizuki for the wet tissue and wipe Uzuki-chan’s ass with it.

Uzuki-chan’s ass was dirty with a color similar to a boiled egg’s skin.

After cleaning it, her ass looks too pure and free of defilement as if to show Uzuki-chan’s pure mind.

Then, Shizuki suddenly came close to me and with her lips close to my ear she whispers.

“Although you finished cleaning U-Uzuki-chan’s ass, you should clean well her pussy so that because it would be dangerous if left like that. I’m sorry for troubling you”

Shizuki whispers so to me. I see. Inside her pussy too, huh?

I nod to Shizuki, then smile while looking at Uzuki-chan. And then I wipe Uzuki-chan’s pussy lips with a new set of wet tissues then look at Shizuki.

Shizuki shows a bitter smile and shakes her head horizontally.

Huh? Isn’t this enough?

When I appeal to Shizuki with my eyes, she nods her head horizontally again.

What do I do. Honestly, I don’t know.

With a troubled expression Shizuki moves her hands towards Uzuki-chan’s butt. And with the fingers of her hands she opens Uzuki-chan’s crack to the right and left.

And the salmon pink flesh walls of Uzuki-chan’s pussy get exposed.

Uzuki-chan’s mind is that of a little girl, but her body is that of a young woman. Even her clitoris if firmly asserting itself.

As I saw it, I scolded myself for looking at her that way. Don’t look at Uzuki-chan with such eyes.

Well, if she opened her pussy like that, it means that I should wipe it firmly even though it doesn’t look dirty, right? I shouldn’t ask too much.

“U-Uzuki-chan, I’m sorry”

Due to the strange guilt building up inside me I instinctively apologized to Uzuki-chan.

Even though I apologized to her, she looks at me with her empty eyes. For her it’s normal to have the insides of her pussy cleaned, it’s natural.

“Onii-chan, why are you sorry?”

Uzuki-chan asked why I apologized due to her anxiousness.

Ugh, this is troublesome, there is no way I can tell Uzuki-chan that I apologized to her to run from my guilt because I felt lust after watching her pussy.

However, I can’t not explain. Even if I explained, it would be too complex of a story for Uzuki-chan, and I would even need to explain to her why I felt lustful.

“This onii-chan is very kind and great. He apologizes as soon as he does anything wrong, And even if your older sister tells him not to do something he will comply, it’s a wonderful trait to be able to recognize your wrongdoings”

Shizuki said to Uzuki-chan after noticing I was in trouble.

“How about Uzuki? Uzuki can apologize properly, right?”

Shizuki provoked Uzuki-chan with a smile. Uzuki-chan pouts at her provocation.

“I can do it! U-chan can do it”

Uzuki-chan raises her hands in protest against Shizuki while blushing.

Shizuki, who is holding open Uzuki-chan’s pussy snorts at that.

Due to that, Uzuki-chan becomes even more irritated, and Shizuki watches her with a smile on her face as a restless air emanates from the two of them.

I don’t care about that, I want to finish cleaning and be done with it.

“Hmm. Even though you don’t listen to what your sister tells you”

“I can do it, U-chan can properly apologize to onii-chan”

“Hee, I see. I want to see you properly doing it after this”

“I hate sister!”

“Ok. Then I hate you too”

A dangerous air began drifting from the two of them while they converse.

Hey, please, can you do that after I’m done changing the diaper?

“Mumumu!”

“Hmph!”

Uzuki-chan gives up the staring contest with Shizuki while pouting.

Because of Uzuki-chan’s mental age, it’s not that surprising to see that attitude from her, but Shizuki, what are you doing acting like a child.

“Onee-chan”

Uzuki-chan unexpectedly forgot about her anger and stares at Shizuki.

“What?”

Shizuki answers without looking at Uzuki-chan’s face.

“Onee-chan, ehm, something is different”

“Huh?”

Shizuki seems surprised at what Uzuki-chan said.

“Onee-chan didn’t meet my eyes. Didn’t meet U-chan’s eyes. Onee-chan looked at U-chan, I’m happy!”

At Uzuki-chan’s words, Shizuki opens her mouth and eyes wide.

Didn’t meet her eyes. I mean, it wasn’t like Shizuki was angry or anything. Maybe because she got scolded by Shizuki. Before she said that because Uzuki-chan was like a child, it was okay.

Maybe she was aware of that. And that’s why she is pleased at Shizuki for getting angry at her. The fact that she got angry means that she cares about what Uzuki-chan does.

“Kuku”

I laugh.

“Who was the one that happy for getting scolded by me, who was it?”

When I say that while desperately trying to bear with my laugh, Shizuki’s face reddens in a moment.

Shizuki who was happy for getting scolded by me and Uzuki-chan who is happy because her sister got angry at her. They definitely are sisters.

As Shizuki’s face reddens more and more, she says “Nothing” without voicing it out.

I wonder if she can’t object even if she wants to.

Whatever, this points to the possibility of Shizuki and Uzuki-chan being on the same level of psychological damage.

“Shizuki-oneechan’s face is becoming bright red. She is cute. Right, Uzuki-chan?”

“Waa, it’s true, she looks like an octopus, cute~”

Uzuki-chan responds and nods energetically.

Then they both stare at me.

Hey Shizuki, don’t decide on your own. But well, if Shizuki is together with me, maybe there won’t be a problem?

“I-I understand”

I answer while sighing and Shizuki gets close to Uzuki-chan’s ear and says.

“See? This onii-chan is kind, right? But, you can’t be selfish just because he is kind”

“Yes, U-chan understands”

Shizuki talks with Uzuki-chan while watching me, and she nods at Shizuki’s words.

Hey, I can hear it all. That defeats the purpose of whispering, if you are going to speak close to the ear, at least speak “HisoHiso”. [1]

“Onii-chan’s cheeks are getting red~”

“Fufu, you’re right, cute, right?”

“Yes, onii-chan is cute~”

I felt my face rapidly becoming hot at their whispers. Shizuki, are you trying to retaliate? All right, go ahead and do it. In return I will get back at you 100 times worse for this.

And this, it has been set in stone that we will enter the bathroom together.
