Chapter 6: Bath and Change of Clothes

"Fuuuuhhh……"

I slumped limply in the bathtub.

My mind, scrambled from all the overstimulation, slowly began to unwind—

"The bath feels so nice…"

Alicia seemed to feel the same.

Her relaxed voice echoed in my head.

After the whole ordeal in the changing area, washing ourselves had been another struggle.

First, her hair was so long that I couldn’t wash it properly. No matter how much I tried, it wouldn’t lather easily, and I ended up using way too much shampoo-conditioner combo (Dad’s, for some reason stocked in bulk).

Then, her skin was so sensitive that when I tried using the exfoliating towel I normally used, it hurt, turning her skin red.

On the other hand, when I tried washing her body with just my hands and soap, Alicia got ticklish, making weird noises and putting me in an awkward mood.

Apparently, even the same kind of touch felt different to her—since she couldn’t predict where I’d touch next, it was closer to being touched by someone else.

"Onii-chan, Alicia-san, how’s the water temperature?"

Yuna’s voice came from the washroom. Did she come all the way here just to ask that?

"Ooh, feels great!"

"It’s really nice~!"

As I replied to Yuna, I idly thought that Alicia’s hair floating in the water looked like jellyfish tendrils.

"That’s good… Well then, I’ll leave your change of clothes here."

"Got it. Thanks!"

"Thank you~!"

With that, Yuna’s presence faded from the washroom.

My little sister was really attentive—going out of her way to bring me fresh clothes.

Hmm… Clothes?

"I wonder what kind of outfit it is~! I’m excited~!"

"—Oh crap!? I’ve been played!"

I scrambled to my feet and rushed out of the tub, bursting into the washroom.

My waterlogged hair clung heavily to my body, but I didn’t have time to care.

"Wh-what’s wrong!? Are we under attack by bandits!?"

Yuna was already gone from the washroom, leaving only neatly folded clothes behind.

"…She got me."

The priestly robes I’d been wearing earlier, along with the spare clothes I’d prepared, had all been taken away by Yuna.

After roughly drying myself off with a bath towel, I picked up the clothes left behind and inspected them.

At the very top was a pink dress—girly, with white frills decorating the collar, cuffs, and chest area.

"!? …I-It’s cute!"

Next was a yellow pastel camisole with a matching ribbon and a pair of shorts. Probably meant to be worn under the dress.

"This one’s super cute too!"

And then… a white slip and panties with pink horizontal stripes—

Wait, what the hell!?

"What the heck was Yuna thinking!?"

"I’m the one who should be asking you that, Onii-chan. What kind of clothes were you planning to make Alicia-san wear?"

A reply came from surprisingly close by. Yuna must have been waiting just outside the washroom.

"But Alicia’s not the one wearing them—I am! I appreciate the clothes, but underwear is a no-go! Underwear is…"

"It’s fine. I bought these by mistake—got the wrong size. They’re too small for me… and I haven’t worn them much."

…Still, she had worn them a few times.

A brother wearing his little sister’s panties? That’s a hard no by any human standard.

"…Can I at least have my own underwear back?"

"No! I don’t want you wearing those! Underwear is important for a girl! Right, Alicia-san?"

"Ikuto-san, I’d feel more comfortable in women’s underwear too… Is that not okay?"

"…Sigh, fine. I surrender. You win."

Once it was two against one, I never stood a chance.

"If you need help putting them on, I can lend a hand?"

"No way! Who’d ask for that!?"

…Like hell I’d let my little sister trample any more of my dignity.

After thoroughly drying myself off (my hair took way too long), I mechanically began putting on my sister’s clothes.

"This underwear is so stretchy and comfortable! Really easy to wear!"

Alicia wasn’t wrong—honestly, compared to the drawstring pants I’d been wearing earlier, these did feel more secure and comfortable.

…But I wasn’t about to comment on that.

"And this outfit is adorable…!"

Leaving the overly enthusiastic Alicia to her own thoughts, I silently finished putting on the rest of the clothes.

Once dressed, I faced the mirror.

Reflected back at me was a version of myself—no, of Alicia—that looked completely, undeniably girly.

Honestly, it suited her way too well. If Alicia were the one wearing this, I’d have praised her without hesitation.

…Well, at least dressed like this, I wouldn’t stand out too badly in public. Small mercies.

After a long stare-down with my reflection, I opened the changing room door—only to find my little sister waiting, smartphone in hand.

"Hey—!? Don’t just take pictures without asking!"

"Come on, it looks great on you. I bought this outfit, but it was too cute for me—never ended up wearing it. Was thinking of giving it to a cousin or something, but I’m glad I kept it."

"…Don’t post it online."

"Obviously. But… you do know pics of you are already circulating, right? Some kinda ‘mysterious foreign loli cosplayer spotted in local city’ thing. Saw it on a tweet roundup—details were vague, though."

Seriously?

Now that she mentioned it, I had noticed people snapping photos of me on the way home…

But for it to get compiled this fast?

Well, as long as nothing personally identifiable got out, it’d just be treated as random cosplay. Best to forget about it.

"…By the way, Onii-chan."

Yuna grinned. A very bad feeling crept up my spine.

"How does it feel… wearing my panties?"

"Wha—"

What kind of question is that!?

Did she seriously think I was some kind of pervert who’d get off on wearing his little sister’s underwear?

I opened my mouth to protest—but then I saw her eyes.

They weren’t laughing at all.

"—If you ever tell anyone about this, the whole world’s gonna know what a degenerate you are for getting all excited about wearing your sister’s panties. So… you understand, right?"

…This little demon just went for a mutually assured destruction play to blackmail me!?

Stunned by her sheer desperation, all I could do was nod silently.
