A Man Who Lost Confidence, to a Gentle Chastity-Reversed World - Chapter 121-125

Chapter 121: The Night Room, Group Chat

Ultimately, Asagi-san woke up just before arrival, stirred by the jolt when crossing a railway with a clunk.

“Mm… Oh, I was asleep… Ugh.”

Her disappointed expression shifts as she notices her position against me, seeming to grasp the situation.

“…I was leaning on your shoulder, Shun-kun… Should’ve stayed awake then… Pools always make me sleepy…”

“Oh, Asagi, you looked so happy sleeping, we didn’t wake you. Shun-kun said it was totally fine.”

After Kurumi-san’s explanation, Asagi-san seems convinced.

“…Got it, I see… Yeah.”

“If you say that and forgive me, Shun-kun, leaning on you was the best. I must’ve used a lot of energy to sleep so soundly.”

Smiling, she says to me:

“So, I rested thanks to you, Shun-kun. Thanks.”

gradually regaining her usual energy.

“…Asagi’s so calm about it…”

Maki-san’s voice, barely audible, comes from beside me as she hurriedly lifts her head.

As she says, Asagi-san apologizes for leaning on me but acts brightly.

Above all, Asagi-san being cheerful is what matters most.

I don’t want to forget to be grateful that she’s okay with my face being right there when she wakes.

“Speaking of, we’re already near home, huh?”

As Asagi-san says, the car travels familiar roads, and soon after her comment, we arrive in front of my house.

It’s just before dark, so Yukari-san and Yuki are likely home.

“Okay, Shun-kun, you can get out.”

Kurumi-san prompts me as the car stops.

It’s the moment to say goodbye to everyone after spending the day together.

Asagi-san says:

“Oh, I’ll get out to see you off!”

and exits with me.

“Th-Then, me too…”

Maki-san follows, making it a send-off by both in front of the car.

They could’ve stayed in the car, but Asagi-san and Maki-san stand before me.

“Next time’s the new semester, huh? I’ll definitely call and stuff, though!”

“…Yeah, thanks, Asagi-san.”

It feels sweet, like a daytime lover’s exchange.

But Asagi-san steps closer, whispering:

“…Shun-kun, I’ll send those two photos later, so look forward to it, okay? ♡”

Her soft voice, inaudible to the car, reaches Maki-san nearby.

“Ugh, Asagi… But yeah, I’m in on it too, so, um, look forward to it…”

Maki-san, startled by Asagi-san’s move, seems to direct the latter half at me.

She’s part of this promise too, naturally.

Just thinking of it, my cock anticipates, my heart craving to jerk off.

It’s too decadent, but I should focus on gratitude now.

“…Thanks too, Maki-san, really.”

Maki-san responds:

“U-Un…”

Our trio, foreshadowing lewd acts, lingers reluctantly but parts for today.

“Hehe! ♡ And Shun-kun, even during summer break, call us anytime you feel like it, okay?”

Asagi-san grabs my hand.

“See you next time!”

Waving cutely, she returns to the car without breaking eye contact.

Maki-san follows:

“Th-Then, see you…”

bowing slightly before getting in.

I wave back to my lovers and everyone in the car.

My expression might be clumsy, but Kurumi-san and Mai-san wave too.

…I’m too blessed, still scared by it.

Alone now, but family awaits inside.

Caught between sweetness and excitement, I exhale.

It’s to calm my heart and shift to family routine.

Actually entering the house, footsteps rush down the stairs.

Yuki appears at the entrance, timed perfectly as if waiting for the door’s sound.

“Welcome back, Shun-nii! Was it fun?”

Her carefree smile prompts me to nod.

“…Yeah.”

But sharing more here isn’t easy.

I know it’s not great going on a pool date, sent off by my studious sister.

“Good! If you had fun, Shun-nii, tell me more at dinner!”

Yuki leaps to my chest, hugging lightly, sniffing.

It’s become routine after I go out with others.

Even routine, I can’t get used to it.

Her white T-shirt, with a white bra faintly visible, fills my view.

After Asagi-san’s exchange, my cock isn’t safe.

I try to stop instant arousal, but my flimsy rationality crumbles in this atmosphere.

“Hmm, guess the pool washed away everything but your scent, Shun-nii.”

Yuki always says heart-stopping things, adding:

“Just kidding! ♡”

with charming flair, undeniably cute.

“Yukari-neechan’s probably cooking, so just put your laundry out, and it’ll be fine.”

I feel a bit guilty.

Going on a date with others and casually leaving laundry feels off, even if it’s late to think so.

But I’ll deal with it later.

For now, I’ll set it aside from the basket and wash it myself tomorrow.

“Yeah, thanks, Yuki.”

“Hehe, I’ll wrap up studying and tidy up! Be down soon!”

Our sibling exchanges stack daily.

“…See you later.”

Even my small addition gets her smile.

At dinner, surrounded by family, I report while watching for my usual fast-talking.

Yuki chimes in:

“Hmm, that waterslide sounds fast. I read it’s speedy and wanted to try it. But sliding this time of year feels like bad luck.”

Mom and Yukari-san listen without interrupting.

“You didn’t seem superstitious, Yuki, that’s surprising.”

“Eh, I’m not super into that, but I know this exam’s important, so I think a bit.”

Yuki, responding to Mom, puffs her chest.

“But I know studying hard matters more. Lately, I’m solving tough past questions pretty smoothly.”

“That’s good. Keep at your pace.”

“Hehe, gotta work hard to be with Shun-nii!”

Holding chopsticks, Yuki smiles at me, always watching me.

“So, Shun-nii, don’t worry about me now—play tons! So you’re never lonely! ♡”

Her kindness sees through my unease, my face too readable.

I know I’m an obvious guy.

“…Yeah, but I want you to be more selfish, Yuki, so it’s okay.”

She pauses, then grins.

“Fufu, thanks, Shun-nii! ♡ That makes me think a bit.”

Mom gently scolds her:

“Yuki, it’s nice you’re excited, but put down your chopsticks.”

“Okay.”

This calm, sweet exchange always surrounds me.

But one thing catches my attention.

“…Waterslide…”

I think I heard Yukari-san murmur softly.

Was it just me?

Dinner and living room time, though impactful, are calm.

Now, after a bath, back in my room, I’m alone.

Even normally, I masturbate nightly to memories of sex or Asagi-san’s bras.

Before bed, sitting on my bed, I grab my phone.

Waiting alone for photos isn’t praiseworthy.

I know, but asked for a solution, only a “wild idea” comes up.

Sending my photo back is for confident, handsome guys.

“Oh, Shun-kun’s here.”

As planned, around 9 p.m., I join our three-person group chat.

Asagi-san and Maki-san had some prior messages, but before I scroll, Asagi-san continues.

“Then, I’ll send the photos.”

One photo starts loading.

Just two seconds feel eternal.

The first photo shows their swimsuit-clad selves.

Asagi-san likely held the phone with her right hand, framing it.

Having been with them, I recall their swimsuit patterns, covered skin, and curves.

As a photo, it reinforces those memories.

Asagi-san, used to it, makes a peace sign with her left hand, smiling.

Maki-san, more reserved, does a small peace sign.

It captures down to their bikini bottoms, just barely.

Their cute expressions and chest sizes are vivid.

It’s more than a youth page.

If classmates posted this on SNS, I’d fantasize.

The blurry background shows lockers, so it’s from the changing room, as said.

I realize this after ten seconds.

My thoughts stall.

Asagi-san sends a second photo.

After a brief load, my spine stiffens.

“!”

I nearly gasp.

The second photo, same selfie angle, shows Asagi-san and Maki-san pulling down one bra strap.

Asagi-san, likely using her right hand for the phone, cleverly reveals her left breast, showing its pink tip and over half its curve.

Maki-san mirrors her, exposing her left breast.

Its softness is clear even in a photo, with a darker nipple freed from the bikini.

Their expressions differ from the first.

Asagi-san’s smile is subdued, Maki-san’s face visibly red even through the image.

But my face reddens too.

This “erotic selfie” makes my cock surge, my agitation unhidden.

Being online helps.

“Shun-kun, what do you think? Exciting enough?”

Asagi-san’s message is a fastball.

Honestly, the more I look, the hotter it is.

Recalling their breasts’ softness, it’s intensely arousing.

I can’t coat my words in lies.

Saying “This doesn’t excite me” or “It’s okay” contradicts everything.

[I think it’s super erotic. Really exciting.]

A childish reaction, sure.

But witty replies in this situation are dubious.

Asagi-san sends a cat hugging a heart stamp, its calm clashing with the mood.

“Good! The first was taken when we got there, but the second was just before leaving, after changing.”

Reading her reply, I try to stay calm.

The location differs, and the second shows wet hair, so they were taken at different times.

“Since you said you’d take the photos, Shun-kun, we took another in the changing room with Maki.”

“We found a corner out of sight, told our moms we were taking photos.”

They got Kurumi-san and Mai-san’s okay, finding a private corner in the changing room.

Even here, photographing others in the women’s changing room might be wrong.

Such effort produced the photo on my phone.

“Swimsuits are fine, but I thought you’d like seeing our chests too, Shun-kun! First time, so our faces are a bit stiff, sorry.”

There’s nothing to apologize for.

Asagi-san’s flood of info makes my cock rock-hard.

[I was worried if it was really okay.]

Maki-san, silent till now, messages.

[Super embarrassing, but if it makes you happy, Sato-kun, I went with Asagi’s idea. If mine’s not needed, you can crop it.]

Cropping is unthinkable.

Their distinct but sexual breasts endlessly fuel my desire.

[No, I won’t do that.]

Typing that first, I slowly choose words.

Polite, but it’s a masturbation declaration.

[Your photos are super exciting, so I’ll use them.]

My words get instant read marks.

My scant normalcy is glitching, lust for the photos spilling out.

“Of course! Being your fap material is thrilling!”

Asagi-san sends a cute stamp.

Maki-san replies:

[Thanks.]

briefly.

“I’ll do it too, thinking of you, Shun-kun.”

Asagi-san’s candid words continue.

I no longer doubt she’ll “do it” thinking of me.

Isn’t this unfair?

I’m getting photos, but giving Asagi-san and Maki-san nothing.

Realizing this, I hesitate for 20 seconds.

To fix it, I’d say something outrageous.

[Asagi, you say that too easily.]

“Yeah, I said the same at noon. Didn’t even get your okay, Shun-kun.”

Amid their exchange, I wrestle.

My earlier thought, hearing Asagi-san’s masturbation plan, solidifies.

[It’s fine, but sorry for getting all the benefits, so]

Pausing, I type the core.

It might trouble them.

[I was thinking, should I send a photo too? If you don’t want it, just say so.]

Since they sent erotic selfies, offering my photo might be too earnest.

Even thinking to take one is conceited.

But they’ve said they masturbate thinking of me.

That, with Asagi-san’s words, births my bold statement.

Chapter 122: Photos from Me, and the Days Continue

But there wasn’t much time to feel anxious. Messages were marked as read quickly, pushing the previous ones upward.

“No way I wouldn’t want it.”

Asagi-san replied instantly, not scolding me even when I let out thoughts that didn’t suit me.

“When Shun-kun says something like that, there’s no way I’d say I don’t want it.”

“And…”

“Honestly, I really, really want it.”

With each progressing message, I found myself holding my breath. After all, when your cute girlfriend says she wants your photo, there’s no way you can stay calm.

[Are you really okay with this, Sato-kun?]

Maki-san’s confirmation helped solidify the atmosphere between us. Even if it was just text, it was no longer something cold or lifeless.

『Yeah, I’m happy you say you want it. If my photo’s okay with you…』

Even though I’m no idol or anything, Asagi-san immediately replied, “I want Shun-kun’s.” The fact that she typed it so quickly made my heart race uncontrollably, as usual.

[For me, anything’s fine as long as it’s from you, Sato-kun.]

With Maki-san’s agreement, I realized there was a step I hadn’t considered. I’m not some outgoing guy, so I’ve never taken a selfie before.

『But I’m not sure what kind of photo to take. Do you have any preferences?』

This time, the response didn’t come right away. Thinking about it, asking “What kind of photo of me do you want?” might come off as creepy, even if it was an honest question.

Both of them were still logged in, so maybe they were thinking it over. Or perhaps they were hoping I’d figure it out myself.

“Really, really okay?”

Asagi-san kept double-checking, and I replied, 『It’s really fine.』 After all, they sent me those kinds of photos, so it’d be unfair if I didn’t at least hear their requests.

“Then I…”

My heart pounded.

“You might think I’m gross, but…”

“Right now, this very moment, I want a photo of Shun-kun’s ochinpo.”

The word ochinpo appeared on the screen, and I instinctively looked behind me, even though no one was there. It was just my room, but Asagi-san’s request had that kind of power.

Calm down, I told myself. Asagi-san wanted this, and while Maki-san said, [Asagi, that’s too much], she didn’t criticize me. I knew these girls wouldn’t laugh at me if I went along with it—they weren’t like that.

『Okay, give me a sec.』

My typing was sloppy as I looked away from the phone.

I’d said it. I’d agreed to this crazy idea. They suggested it, and I accepted.

Sorting through my jumbled emotions, I switched screens and opened the camera app.

“Better not show your face. Just in case it leaks, it could cause problems for you, Shun-kun.”

Before I started the camera, I saw Asagi-san’s message. It reminded me of girls hiding their eyes in risqué selfies—a precaution.

『Got it.』

After a short reply, I turned on the front camera, focusing on my chinpo. From my lower stomach to my member, I wondered if this was okay as I snapped the photo.

It came out too well. My rock-hard chinpo was captured vividly. Normally, if anyone saw this, they’d mock me, saying, “Why’d you take something like this? Gross.”

But even though I was scared, I was about to send it. I’d selected the image and was hovering over the send button. It was a grotesque, lust-driven photo. The fact that Asagi-san and Maki-san were still logged in, waiting, felt utterly surreal.

Still, if they wanted it, I made up my mind and pressed send.

After a few seconds of loading, the image appeared in the group chat, marked as read by both. I was terrified of their reactions, even wanting to take it back, but that anxiety lasted only about ten seconds.

[That’s too erotic.]

The first reaction came from Maki-san.

“This is insane.”

Asagi-san followed with a short reply, then added more.

“Sorry, Shun-kun, but honestly, I’m totally going to use this as okazu.”

“Please forgive me.”

In this relationship where we explored each other’s desires, mutually accepting masturbation made my chinpo twitch. The idea of Asagi-san and Maki-san getting off to me was, to me, outrageously erotic.

There was no way they were plotting to mock me. This conversation, this moment, was nothing short of extraordinary.

『If it’s okay with you, you can have as many as you want.』

“Shun-kun’s is the one I want.”

Our earlier exchange now carried a lascivious tone.

“Shun-kun, even though it’s always such naughty stuff, thank you so much.”

[I’m honestly not sure how to thank you.]

Maki-san’s follow-up made me feel like my chinpo was somehow valuable, despite being weak and drowned in lust.

『Just talking with you both makes me so happy.』

『Plus, I got photos from you, so I’m the one being unfair.』

I had to let out my true feelings.

“We’re the ones getting the better deal.”

[Really, it’s true. Saying you’re happy just talking to us…]

They responded to my maybe-too-honest feelings with immediate kindness. The endless humility could’ve gone on, but in the end, we’d exchanged photos. So, Asagi-san sent a final message to wrap things up.

“So, Shun-kun, if you ever want something else, just say so, anytime.”

A cute sticker was attached, though it felt a bit out of place in this situation.

[You can ask for mine whenever you feel like it.]

Maki-san’s message, sent after a slight delay, only added to my racing heart.

“And if you report back like before, I’d be super happy. Of course, only if you feel like it!”

Reporting back like before—meaning, telling them if I masturbated to them. It was an impossibly heavy, insanely erotic promise that had already been sealed.

※

In the end, after pausing the conversation, I immediately started jerking off. When my two girlfriends say they want me and ask for masturbation reports, I have no choice but to get off to their photos.

The first photo, wholesome yet captivating. The second, an indecent vibe just for me. Both drove my excitement to insane heights. My breathing was ragged, precum was starting to leak, and I felt like I’d cum any second.

Were Asagi-san and Maki-san waiting for me to finish? That thought alone made my chinpo jump, and byuru byuru, I started shooting semen.

Holding a tissue, I looked at the second photo, and my arousal surged again. The semen still coming out was caught by the thin paper.

It felt so good, so thrilling, that there was no such thing as post-nut clarity. My chinpo was still rock-hard, and honestly, I could probably cum again.

I’d masturbate again later, I thought, but for now, I returned to the group chat and typed a message. I had to report my first session to them.

『Thanks for the photos. I used them.』

『It was really exciting.』

I laid out the blunt, unavoidable truth.

“Awesome! Thinking about you masturbating, I did it too! It felt so good.”

Asagi-san’s masturbation report was cheerful but still stirred my imagination. I’d seen her masturbate once before, so my mind easily wandered there.

[I’m the one who’s really happy.]

Maki-san’s words followed, and I replied, 『Thank you so much.』 At nearly 10 p.m., we were connected online in a sexual bond.

We chatted a bit more before calling it a night, with them thanking me for hanging out all day.

But that night, I ended up masturbating one more time. Imagining Asagi-san’s self-pleasure and recalling the feel of Maki-san’s breasts from earlier that day, I shamelessly came again.

※

The next day, I woke with pleasant exhaustion and none of the usual post-masturbation sluggishness. Compared to my old world, recovery after ejaculation seemed faster here.

It was a day off, but I got up properly. Checking the clock, I noticed a new message notification on my phone.

Had they sent something I didn’t reply to? Suddenly wide awake, I hurriedly unlocked my phone and checked the time. It was just ten minutes ago, so I relaxed.

But the content was far from wholesome.

[I ended up doing it a lot to your photo, Sato-kun. Sorry.]

In our private chat, Maki-san had sent that. My heart leapt, realizing she’d masturbated to me yesterday too. Her wording made it seem like she’d hesitated to mention it, even adding an unnecessary apology.

『Thanks, Maki-san. Hearing that makes my heart race.』

Combined with morning wood, my chinpo was ready to spring to life. Jerking off before breakfast wouldn’t be great, but the excitement was undeniable.

[Thank you, Sato-kun.]

Maki-san kept thanking me, over and over. All I could do was thank her back, even more.

※

Getting out of bed, I checked the sunny weather through the window and headed to the bathroom. It was a bit late, around the time Mom would leave for work.

I’d stay home today. Homework was done, but I should study, I thought as I turned on the faucet.

“…Ah.”

But as I washed my face, I let out a small sound. The bag with the swimsuit I’d left by the washing machine yesterday was gone.

More than that, the washing machine was running nearby. It was probably mixed in with other laundry. I felt like I’d messed up. I should’ve washed it myself instead of adding to Yukari-san’s workload.

After breakfast, I’d have to apologize. Reflecting on that, I headed to the dining table. Just then, Mom came out of the living room.

“Oh, Shun-kun, you’re up. Good morning.”

“Good morning, Mom.”

I managed to greet her without stuttering—maybe I could handle family. A small step forward.

Dressed in a suit, or rather just a blouse since it was summer, Mom said, “Phew, it’s supposed to be way hotter than yesterday. Be careful of heatstroke, Shun-kun.” She passed me, heading to the door.

“Yeah, thanks.”

“Hehe, you’re welcome.”

Mom’s gentle smile created a calm atmosphere, even with my short reply. I saw her off and headed to the dining table.

※

“Um, Yukari-san, did you maybe… wash the swimsuit I left by the washing machine…?”

After eating with Yuki and Yukari-san—or rather, while they watched me finish—they were done, and I asked Yukari-san.

“Oh! Y-Yes, I thought you used it yesterday, so I washed it. Was that… a bother?”

“N-No, not at all! It’s just, since I wore it for fun, I thought I should’ve done it myself… Normal laundry’s one thing, but, I mean, maybe it’s too late, but was that okay…?”

Anyone who’d call her a bother deserves to vanish. She always does the laundry, and this was an irregular item, so I should’ve been more considerate.

“It’s fine! It’s not something for you to worry about, Shun-sama. I appreciate your concern, but this is my job, so… thank you!”

In the end, she thanked me, and her face seemed a little red. Probably my imagination.

“…If anything, I should thank you for always doing the housework.”

“Yeah, Yukari-neechan’s always working hard! If you need help, I’m here. We’re family!”

Yuki’s supportive words made me nod slightly.

“…Even Yuki-sama… Thank you so much…!”

Seeing Yukari-san thank us repeatedly, even looking shy, calmed my heart. She’s why I can live like this.

Yesterday, Asagi-san and Maki-san stirred my emotions. Now, Yukari-san and Yuki were guiding me to a peaceful daily life. Thanks to everyone, I could live in this world with less fear.

※

Life moves forward, not just with big events. Taking skinship with Yuki or messaging Asagi-san and Maki-san at night made this week enjoyable.

Yuki chose talking with me as a break from studying hard. That made me happy, but on the sofa, she’d practically sit in my lap, making it hard to avoid inappropriate feelings.

Her feminine scent, glossy hair, often-revealed chest, and occasional thigh brushes—her charms were right there.

“Hehehe, I’ll snuggle even closer!”

But above all, it was Yuki’s radiant smile when we were close. That expression melted my heart every time.

※

With peaceful and sweet days, Friday arrived. Our family’s one-night, two-day hot spring trip was tomorrow.

“Because of check-in, we’ll leave at noon tomorrow. Even if Yuki’s too excited to sleep, it’s arranged to be fine.”

“Ugh, so that’s what you meant, Mom. Well, maybe it’s true.”

That night, after Mom returned from work, we sat around the dining table. Yukari-san and I had prepared everything during the day, so we were set.

But whether my heart was ready was another matter. We’d visit not just regular hot springs but a family bath.

I learned that in mixed baths here, men cover up to their chests, like women in my old world. Mixed baths were also rarer here.

Thankfully, women’s customs were similar to my old world. If they only covered their waists like men there, it’d be problematic. Less exposure was better, and I was grateful for that.

…I hoped the family bath followed the same logic.

“Still, don’t stay up too late. Keep studying and talking with Shun-kun in moderation, okay?”

“Okay!”

“And, Yukari-chan, thanks for driving. I can take over if needed.”

“Y-Yes! Leave it to me!”

As the three of them talked, Mom turned to me.

“Rest well, Shun-kun. Once we’re there, Yuki will probably want to play a lot, and we plan to stroll the nearby hot spring town.”

“…Got it.”

I nodded slightly to Mom, who always thought of me.

“Mufufu, I’m fine just relaxing, Shun-nii. As long as we’re together, anything’s great! ♡”

Yuki’s adorable smile and kindness overflowed.

※

After a bath, back in my room, I checked my belongings. The big luggage was already in Mom’s car, so I just looked at my usual bag.

A family trip—it felt like a truly happy plan. In my old world, I vaguely remembered going as a kid, but as I withdrew, those memories fogged over.

If I’d stayed mentally strong, maybe I could’ve been close with family as an adult. They never outright insulted me, so if I’d had confidence, there might’ve been a chance.

But I ended up unable to act “human,” letting those opportunities slip.

…Could I, now, invite someone on a trip? Would that still be too bold for me?

“…It’s late.”

I muttered to myself. Unless I suddenly returned to my old world—which was unlikely—that wasn’t the issue.

I hadn’t fully let go of regrets from my old world. But living here, my job was to connect with people. Neglecting that would worry my family and girlfriends here—people who cared about me.

Cherish each day, enjoy events. Maybe I had to accomplish what I couldn’t in my old world.

I wouldn’t forget my old world but wouldn’t dwell on it. Resolving to value this world, I slipped into bed.

“Have fun starting tomorrow!”

Asagi-san’s message had arrived earlier. The kindness from her and others was something I could never let go of.

Chapter 123: Heading to the Inn, Walking the Town

Even knowing I didn’t have to wake up early, my eyes opened at the usual time. I think I slept well, and there’s no particular physical discomfort.

In fact, when I glance from the bed to the full-length mirror, the usual me is reflected. My skin might look a bit better than when I first arrived, but it’s not a dramatic change, and I still can’t be called handsome by any stretch.

Yet, this me, along with Mom, Yuki, and Yukari-san, is undeniably going on a trip. It’s an indisputable fact, with departure just a few hours away.

“…Alright.”

For now, I head to the dining table as usual. No matter what kind of day it is, that’s where it starts.

※

At the first-floor dining table, Yukari-san and Mom are arranging toast on plates for everyone. Seeing me, Mom smiles gently and says, “Oh, Shun-kun, you’re up. You could’ve slept in a bit more.”

“Then we’ll get your portion ready. Just a sec.”

“Ah, this time I’ll—”

“Hehe, it’s fine, Yukari-chan. We’re making you drive today, so take it easy and eat. I’ll grab Shun-kun’s salad too.”

Yukari-san, who’d started to stand, sits back down with an apologetic look. She glances at me and says, “G-Good morning…” still greeting me as always.

“…Good morning. Um, thank you for today.”

Normally, Saturday would be a day off from her housekeeper duties, but she’s driving us. I have to express my gratitude first.

“N-No, I should be the one…”

She gives me polite words I don’t deserve. Meanwhile, Mom brings plates to me one by one.

“Shun-kun, ketchup on your fried egg?”

“Yeah.”

It seems Mom’s handling all the cooking this morning. That’s probably why Yukari-san looks apologetic and why the salad’s presentation is slightly different. Also, Mom’s casual T-shirt and light pants might be chosen for cooking convenience.

Her long hair, usually down, is lightly tied back with a hair tie, and I find myself staring a bit. Even though she’s beautiful, it’s a bad habit of mine.

“Guess that’s one place we’re not quite alike. Is my salt preference that unusual?”

She talks cheerfully, and my breakfast is prepared in no time. Everything except the fried egg and toast seems to have been made earlier, including Yuki’s portion.

“Yuki doesn’t seem to be up yet, so go ahead and eat. She’s probably saving energy for today, sleeping until the last minute.”

Following Mom’s words, I start eating. She usually leaves cooking to Yukari-san because of work, but Mom must love it. The meal feels gentle, comforting.

※

As Mom predicted, Yuki wakes up pretty late, muttering, “Ugh, I overslept a bit…” with a slightly frustrated air.

By eating slowly, I manage to sync with Yuki, who arrived late. Since she always eats with me, there’s no reason I shouldn’t do the same.

At the end, Yuki says, “Thanks for waiting!” My small gesture earns her blooming smile.

Kindness piles up even before we leave, but after breakfast and some chatting, the scheduled departure time arrives quickly.

※

Once we’re ready, we gather at the front door.

“Alright, the luggage is loaded. You two, get in first.”

Locking the door, Mom speaks as Yuki and I, who’d been loading the car in the parking space, climb into the back seat. Yukari-san takes the driver’s seat, and Mom checks outside, guiding the car.

Yuki and I already have our seatbelts on. But by the time the car hits the road and Mom climbs in, Yuki’s already scooting close to me, giggling, “Hehe! ♡”

“Hey, Yuki, don’t lean too much. Shun-kun might get hot.”

“Okay, I’ll be careful!”

She replies playfully and backs off a bit. Still, her line, “Shun-nii, is this okay?” paired with a slight upward glance, is very much there.

“…Yeah, it’s fine. Thanks, Yuki.”

“No, I’m the one who’s thankful.”

With our arms just touching, there’s no way I wouldn’t allow it. Being this close always demands my utmost gratitude.

“It feels like we could stay like this forever! ♡”

But before I can express that, her innocent cuteness pins my gaze. I’m already convinced I can’t win against her.

The hot spring inn is about a two-hour drive, Mom says in the car, mentioning a break at a service area along the way.

“I told Yukari-chan we could switch drivers each time, but she insisted on working since we’re bringing her along.”

“N-No, being included in a family trip like this, the least I can do is…”

“Come on, don’t be so formal. Just say if you get tired. It’s been about an hour, right?”

As Mom says, about 50 minutes have passed since we hit the highway from local roads. It’s the last weekend of summer break, so the roads are a bit busy but not gridlocked. Progress is smooth, and Yukari-san’s driving has covered good distance.

“Wow, it’s been that long? Didn’t even notice.”

Yuki, chatting with me or Mom, has kept the mood lively. Mom, in the passenger seat, responds, and Yukari-san, driving, seems to listen through the rearview mirror.

I reply carefully. Even with daily sibling talks, I’m never confident my words are proper.

But seeing Yuki lean toward me, laughing happily, makes me feel almost smug. She’s my cute sister, a beautiful girl with lingering childishness, still unguarded.

It’s fairly hot, so Yuki’s T-shirt is a bit loose at the chest. Since I’m taller, I catch glimpses of white fabric through the gap—something I shouldn’t see.

Does Yuki, never dropping her smile, notice my gaze?

※

At the service area we stop at, Yuki’s “I want ice cream!” leads to buying some snacks.

“Come on, Yukari-neechan, eat something too!”

“Y-Yes, then, excuse me…”

“Oh, Yukari-chan, I said we’re covering today. No wallet!”

“S-Sorry… Thank you…”

Mom stops Yukari-san, who’d reached for her bag, with a smile. So, all four of us end up eating soft-serve ice cream.

“Hehe, this feels new. Like a real family.”

Mom’s enjoyment is heartwarming, and Yuki munches her strawberry soft-serve, saying, “Mmm, sweet.”

“…It calms my heart.”

Yukari-san, eating vanilla, reassures me too. Her cheeks are slightly flushed as she works through the white cream.

…A beautiful woman eating ice cream is a lovely sight, but it also feels a bit unguarded.

“Shun-nii, it’s melting!”

Yuki’s voice snaps me out of staring. I hurriedly eat, unable to admit I was captivated by Yukari-san’s eating.

The matcha flavor is sweeter than expected, rejuvenating my brain. But maybe as punishment for my stray gaze, it feels a tad colder than I’d imagined.

※

After leaving the service area, the seating stays the same, as do Yuki’s cheerful expression and tone.

Her energy, along with Mom and Yukari-san’s, makes me smile a little. Before I can worry if my smile is ugly, Yuki pulls me into conversation.

“So, I was thinking of cutting my hair soon, but maybe I should ask Shun-nii first?”

One of Yuki’s questions carries a certain weight.

“It’s just the right length to tie up now. But maybe a short cut could work too.”

“Now that you mention it, Yuki, you started growing it out last winter, right? You were thinking Shun-kun might like it long.”

“Yeah, I couldn’t quite ask Shun-nii directly.”

Their conversation reveals Yuki’s feelings.

Even before I started living in this world—when “he” wasn’t talking with Yuki—she was thinking of her brother as a sister.

Her earnest, straightforward nature, and the brother who, because of this world, distanced her. I’d vaguely understood before, but now, my heart tightens again.

“…I really like your current hairstyle.”

All I can do now is weave the present. If past actions hurt her, I need to apologize, but they can’t be undone.

“Mhm.”

Yuki listens, and I keep speaking.

“But I’m sure you’d look great with a short cut too. So, um, I want you to have the hairstyle you want.”

I want Yuki to choose her style and do what she loves. I’m grateful she cares about my preferences, but her hair—a girl’s important feature—shouldn’t be swayed by my fleeting feelings.

“…Hehe! ♡ Okay, if Shun-nii says so, I’ll think about it a bit more.”

I was ready for her to call me indecisive, but Yuki responds with kind words and leans closer to me.

“Honestly, Yuki, don’t spend too much at the salon, okay?”

“Don’t worry, Mom!”

Replying to Mom, Yuki leans into me again, looking up at me.

“…Shun-nii, you’re so kind, hehe.”

Her soft, clear voice reaches me.

※

The conversation pauses when we see a sign indicating the inn is near. Yuki’s “We’re almost there!” shifts the mood to arrival.

Driving up a slight hill, we see the two-story building from the photos. The limited parking spaces suggest it’s not a place for large crowds.

I think it’s a relatively new building, not an old traditional inn. A blend of Japanese and Western styles, the lobby allows shoes, with a Western-style terrace and a small café-like area. The main building has both Western rooms with beds and tatami rooms.

…But we’re staying in a detached Japanese-style room down a path. That alone marks it as a high-end inn. In my old world, I’d never stayed anywhere like this—business hotels were my limit.

Mom is composed, and Yuki, saying, “Wow, cool!” is curious but not nervous. Maybe even the old me had stayed in fancy hotels?

“We’ll have them hold our luggage and explore the area below, then check in later.”

The woman at the front desk, dressed in typical hotel staff attire, takes Mom’s instructions. I’d researched hot spring inn etiquette, but it seems unnecessary here. Maybe the staff for the detached rooms wear traditional clothing.

“That terrace looks nice. I wanna sit there and take pics later!”

Yuki, liking the vibe, remains enthusiastic.

“I had a feeling you’d say that. I’ll take your picture later.”

“Promise!”

After handing over the large luggage, we leave the building as planned, heading to the town below on foot, using a staircase opposite the hill we drove up.

“There’s not just souvenir shops but an area like a festival fair, so let’s take our time until evening. Rest if it gets too hot, though.”

“I’ve prepared some bottled drinks, just in case.”

Listening to Mom and Yukari-san, Yuki and I reach the bottom of the stairs first—more like I’m keeping up with her fast pace.

“Shun-nii, I got a bit too quick, sorry!”

“It’s fine.”

After that exchange, Yuki smiles and takes my left hand. Her small, soft hand never fails to make my heart race.

“Thanks! ♡ Oh, look, Shun-nii, over there!”

She points with her left hand to a zone with a festival fair vibe.

“…Like Mom said, it’s like a festival. So today, I want us four to enjoy it like a summer festival!”

Yuki starts pulling my hand but looks back at me, as if checking my words. At least, that’s how it feels.

“…Yeah, I want to have fun too.”

Yuki grins, “Nihehe.” Her expression is my support and salvation.

“Okay, okay, today’s a reward for Yuki’s hard studying, right?”

“I-I’ll humbly accompany you!”

From behind, Mom and Yukari-san approach slowly, responding to Yuki. She then suggests brightly, “Alright, let’s all do that shooting gallery over there!”

※

In the hot spring town, we dive into an area with a festival fair atmosphere. As Yuki suggested, we all try the shooting gallery for prizes.

“Ugh, I didn’t hit anything… Why’s Mom so good at this?”

“I used to be pretty good at these things.”

The result: Yuki’s total loss, while Mom hits about 90% of her shots. Yukari-san and I manage around 40-50%.

“But in the end, Shun-kun got that stuffed toy for you.”

“I wanted to hit it myself… But I’m really happy Shun-nii got it for me.”

As they talk, the bee stuffed toy Yuki desperately aimed for was clearly something she wanted. I think it’s a theme park character, but it’s not light, so it was tough to knock down.

Wanting to help, I started aiming for it with her in the latter half, timing my shots to avoid interfering.

Back then, Yuki said, “Oh, Shun-nii’s going for it too? First one wins!” But I had no intention of taking it. I just wanted to get it for her.

It was tough, but I managed to hit it, and I handed the prize from the stall worker to Yuki.

She asked, “…Is that okay?” But since it was what she wanted most, I nodded.

“If it’s something Yuki wants, I want you to have it.”

Her sun-like smile was almost blinding.

“Even here, I got a present from Shun-nii.”

Now, hugging the bagged toy, Yuki walks happily. Yukari-san offered to carry it, but Yuki refused, saying, “No, I’m good!” and keeps it with her.

“…Hehe! ♡”

Her occasional smiles at the toy are impossibly cute.

Am I too simple? I wonder, but Yuki’s “Next, ooh, chocolate bananas!” pulls my attention, and I walk the town with the three of them.

Chapter 124: Soaking in the Footbath, Returning to the Inn

“Phew, there’s so many fun things to do here!”

“Hey, Yuki, finish eating before you talk, okay?”

“…Mmph, okay.”

After passing someone in a yukata, Yuki, still munching on a chocolate banana, speaks up. Scolded by Mom, she swallows and points at a sign ahead, saying, “Alright, let’s try yo-yo fishing next!”

Even in the daytime, this place is filled with festival-like attractions, likely its main draw. Besides our inn, there are other lodgings nearby, and their guests seem to gather here too.

“Well, I get why you’re so excited. It really feels like a place that brings back your inner child.”

“Yes, it reminds me of enjoying places like this when I was younger!”

I silently agree with Mom and Yukari-san’s words. Though for me, it’s a memory from elementary school, and after that, I rarely hung out with anyone.

Purely enjoying a festival feels like a distant past for me now. The history of losing my ability to enjoy things is something deeply frightening.

“Look, freshly made hot spring manju!”

But Yuki’s words erase any time to dwell on that history. She’s always—always—crushing my negative emotions.

“Okay, okay, don’t eat too much. We’re having dinner at the inn.”

“Ugh, right… Then just one instead of two…”

Yuki looks a bit reluctant, but her exchange with Mom stays cheerful. Then, with an “Ah!” she seems to have a brilliant idea.

“If I split that one with Shun-nii, it’ll be perfect! Is that okay, Shun-nii?”

Her ability to pull me into her atmosphere warms my heart instantly.

※

After splitting the hot spring manju, we struggle with goldfish scooping—where Mom, unsurprisingly, excels—or watch Yukari-san meticulously complete a candy mold with stunning precision. We’re enjoying all sorts of activities.

At goldfish scooping, Mom says, “It’s all about that split second in the water—my mom taught me that,” while Yukari-san, on the candy mold, shyly admits, “I’m decent at detailed tasks.”

Learning things I wouldn’t normally know feels precious, and our time flies by.

※

“Phew, we did a lot! But this is kinda refreshing.”

Now, we’re resting at a footbath area in the town’s center, sitting in a row. It’s check-in time, so we’ll head back to the inn after this.

Being central, the area’s crowded, with various conversations mixing in the air. As expected, most voices are female.

Yuki’s on my right, Mom’s beyond her, and Yukari-san’s on my left, creating a calm family vibe amplified by the warm water. But rolling up pants and removing socks, exposing bare legs, adds a certain rawness. Even if Mom and Yukari-san only show below the knees, their beautiful legs are undeniable.

“Hmm, Shun-nii’s legs look longer, don’t they? My calves aren’t that long.”

Yuki, sitting right next to me in shorts, has her thighs just barely visible, so close.

“Can you stretch out your legs for a sec, Shun-nii?”

When I extend both legs, she does the same, sighing, “See, I knew it,” sounding a bit disappointed. This inevitably draws my attention to her bare legs.

“Is that so…?”

“Maybe just a bit, but you’re still growing, Shun-nii. Plus, Yukari-neechan’s legs are even longer.”

“E-Eh, I-I’m not…”

When I give a vague reply, Yuki affirms it and shifts to Yukari-san. A shy voice comes from my left, but Yuki presses, “No way, your legs are gorgeous! Can you stretch them out too?”

“Y-Yes, understood…”

Careful not to let her pants dip in the water, Yukari-san extends her legs. I knew she was well-proportioned, but seeing it now, her slender, long legs are strikingly beautiful.

“Wow, totally different! I gotta grow more.”

“I-I’m flattered…”

Yuki stares at our legs but eventually says, “Oh, sorry, I was totally staring,” and pulls her legs back.

※

To keep the conversation going, to not just receive Yuki’s words—

“…I think your legs are, um, p-pretty, Yuki.”

Crushing my fear of sounding creepy, I speak. Regardless of length, her bare legs always dazzle me.

“Ehehe, thanks! ♡” Yuki gives me a lively smile, sparking a huge thrill in me.

“And if you eat well and sleep enough, it’ll be fine, right? You’re in your growth spurt, Yuki.”

“Well, yeah, Mom’s got long legs too, so maybe when I’m older, I’ll get there!”

“Flattery won’t get you anywhere.”

“No, it’s true! Right, Shun-nii?”

Yuki’s words make me notice Mom’s legs too. I’m not in a position to compare whose legs are long and beautiful, but I can confirm Yuki’s right.

If someone called me shameless, I’d have no defense, and I’m at a loss for how to respond. But Mom shifts the topic, saying, “Well, legs aside, let’s head out soon,” and I feel a bit relieved.

I’d used a footbath once in my old world, just passing by. I never realized how different it’d feel with close female companions.

…It’s my lack of preparation and tolerance, I suppose.

※

With check-in time here, we head back to the inn. Climbing the stairs we descended earlier isn’t tough with all four of us, especially since they’re neither steep nor numerous.

“…Shun-kun, you used to lag a bit on these, but you seem fine now.”

Midway, Mom checks on me, noting my steady breathing and deeming me okay. The old me in this world probably wasn’t very fit.

“You’re getting stronger—really growing, huh?” she chuckles.

I know my stamina comes not just from PE but from repeated intimate moments. So, while I nod, I can’t help but look down a bit.

“Soon we’ll be there. What should we do? Hit the room’s bath first?”

Yuki, voicing her thoughts openly, is as excited as ever. But her suggestion shakes my emotions—it’s the certainty of all four of us bathing together.

“…Yuki, you’re too relaxed about this.”

Mom, shifting from her earlier warmth, even sighs—a rare expression.

“Is Mom… not really up for it?”

If that’s true, it’s definitely because of me. If she agreed impulsively but actually dislikes it, I want her to say so. So I ask.

But she pauses, “Oh, um,” before sharing her feelings.

“It’s not that I’m against it. It’s just been a while since I’ve bathed with others, and I never imagined doing it with you, Shun-kun. I just can’t picture how it’ll feel.”

At that, Yuki, walking ahead, turns back, and Yukari-san nods vigorously beside me.

“…True, I couldn’t have imagined this last year. And normally, we’d be asking you if you’re okay with it, Shun-sama, so it feels a bit odd…”

“Exactly. I was shocked you agreed to Yuki’s idea, Shun-kun. And to think you’re okay with me joining, not just Yuki and Yukari-chan.”

Agreeing with Yukari-san, Mom continues.

“I’m starting to understand you don’t mind skin-to-skin bonding, Shun-kun, but I might be the one not handling it well. Still, if you’re not against it and actually want it, I’m definitely looking forward to it.”

Adding, “…Is that a bit embarrassing?” while fanning her face, Mom prompts Yuki to sigh in relief, “Phew, good!”

“I was thinking I might’ve been too pushy back then.”

“Well, you’ve been a bit selfish lately, Yuki. I’ll keep an eye on you from tomorrow.”

“I’ll be careful from tomorrow, hehe.”

After their exchange, I search for my words and direct them to Mom.

“…Thanks, Mom. I’m, um, looking forward to it too.”

My plain words earn a calm smile from her.

“Hehe, thank you, Shun-kun. But somehow, hearing you say that makes me kinda nervous.”

I’m the one who’s nervous, but her words keep the mood from staying calm. Yukari-san’s tense air beside me, Yuki’s “Hot springs!” cheer as we reach the top, and our group of four are steps away from the inn.

※

Back at the lobby, we’re briefed again and guided to the detached room. The main building has small recreational areas, like table tennis for Japanese-style fun and darts for Western.

A covered walkway from the building splits—one path to the public baths or open-air hot springs, the other to our detached room.

“From here, use the keys we gave you to open the door.”

A different woman in a kimono guides us, likely for the detached rooms. She points to a keyhole by the door, and when Mom uses the key, the automatic door opens, prompting an “Oh!” from Yuki.

A short, roofed outdoor path leads to several single-story buildings. We’re taken to the farthest one, marked with a sign reading “Ayame” (菖蒲) by the sliding door.

“This is a sliding door, but it uses the same key. You can lock it from inside, so please do so at night.”

I’d researched a bit, but opening the door reveals a small traditional Japanese house. There’s a tatami room for four, an engawa porch with a view of curated nature, and a space for laying out futons.

…It’s even more upscale than I imagined. The website showed a steep price for a one-night, two-day stay, but seeing it now, it makes sense.

“…That’s the general explanation. If you have questions, please contact the front desk. Dinner is at 6 p.m. in the main building, correct?”

“Yes, that’s fine.”

“Understood. I’ll take my leave.”

The woman, likely the inn’s manager, bows and departs. It’s about 4 p.m., leaving some time.

“About two hours left… We could play in the main building.”

Mom starts to suggest, but Yuki cuts in, “Eh, how about instead—”

“We’ll hit the public baths tonight, so why not wash off the sweat now? We’ve got that bath ready, like we talked about, right?”

Grinning, Yuki asks us, clearly eager. At least, that’s how I see it.

“…You’re really eager to get in. Well, we did walk a lot, so maybe it’s not a bad idea.”

Mom, sharing my guess, asks, “Shun-kun, Yukari-chan, is that okay?”

“Y-Yes, I’m fine with it either way!”

Yukari-san, blushing slightly, agrees, so I’m bound to follow. I know bathing together is a big deal, but backing out now would be absurd.

“Yeah, I’m okay with it.”

“Yay!”

Yuki’s innocent joy contrasts sharply with Yukari-san’s small sigh.

“…Alright, let’s unpack and get ready.”

Mom, hand on her chest, pauses before urging us. Even after her earlier explanation, I can’t help but wonder how she feels right now.

Chapter 125: Before Bathing, Facing and Scrubbing Backs

After organizing luggage and checking the facilities, we head to the private bath in our building. I believe all eight detached guest rooms here come with their own baths.

“Shun-kun, how about you undress and get in first instead of all four of us stripping together? You know, just in case, and we’ll join you shortly.”

Mom’s suggestion in the living room is honestly a huge relief. Even though the changing area is decently spacious, I can avoid being there while three people undress and wrap towels around themselves.

As I agree, Yuki pauses for a moment but then puts a finger to her lips, saying, “Yeah, that might be better,” seeming to understand. Perhaps she and Yukari-san know I’m a guy who’d easily get aroused. It’s embarrassing, but true.

“…Oh, right, I wanted to wash Shun-nii’s back! Just his back and hair!”

Yuki’s proposal, made as if in exchange, emphasizes “back and hair,” making my heart skip a beat. It forcibly reminds me of when she washed my hair at home and then licked my chinpo.

“…Yeah, that’s fine. I’ll wait without washing those.”

Though I feel uneasy accepting this openly in front of Mom and Yukari-san, there’s no reason to refuse.

“Alright! Mom, Neechan, is it okay if I do it?”

“…With you looking at me like that, how could I say no? I won’t steal your spot.”

“I-I agree, especially today, Yuki-sama’s wishes should come first!”

“Hehe, thanks, you two! ♡”

Not just Yuki’s words, but Mom and Yukari-san’s responses make washing my back sound like some coveted privilege. Then Yuki smiles at me, saying, “Okay, Shun-nii, go ahead first!”

Obviously, I need to wash my front myself. I can’t let it turn into a situation where Yuki removes my towel to wash my chinpo in front of everyone. That’s surely what I need to glean from her “just the back” comment.

…Should I wash Yuki’s hair in return? Is it wrong to think that?

※

In the changing room, I prepare a long towel and start undressing. The four baskets are helpful, but thinking about women’s shirts and underwear being placed in them later stirs foolish emotions.

I absolutely can’t get hard, I tell myself, yet muku muku, the feelings well up.

I need to calm down while washing my front. Opening the door, I see a cypress bath big enough for about five people and four bath stools. It’s clearly designed for groups like families.

A large window covering over half the wall offers a view of a manicured garden, and opening it could turn this into a semi-open-air bath. The calm atmosphere is perfect for a leisurely soak.

It’s truly a nice place. But I can’t dawdle, or I’ll keep the three waiting. Sitting on a stool, I check the mirror and wash my chest, legs, and gusoku. Even with a towel, knowing a beautiful girl and women will soon enter makes it impossible not to be nervous.

…Nervous, yet half-erect—proof of my perverseness. My emotions keep swirling.

“Shun-nii, can I come in?”

Yuki’s voice signals it’s time. They’ve probably waited a few minutes, and I can’t keep them standing any longer.

“…Yeah, it’s okay!”

Sitting on the stool with the towel wrapped as planned, I raise my voice. With the window closed, it echoes more than expected.

“Okay, coming in!”

When Yuki enters first, I’m relieved to see her properly wrapped in a towel. Still, her loose hair and bathing attire are undeniably alluring.

“Wow, this is amazing! You can really see outside!”

Yuki admires the view but soon pulls a stool next to me.

“…I’d love to wash your front too, but since we’re all together, I’ll hold back.”

Her whisper in my ear, despite its cute tone, grips my lust tightly. My chinpo, hidden by the towel, is on the verge of tenting.

“Yuki, you went straight to Shun-kun. Well, it’s fine.”

I turn at Mom’s voice, worried Yuki’s words were heard.

But that was reckless. My vision now holds Mom and Yukari-san.

“…Shun-kun, you okay?”

My shifting gaze makes Mom worry unnecessarily. But her appearance, new to me, could stir odd feelings if I stare too long. Her slightly wavy hair is down, and the white towel wraps a mature woman’s body.

“Y-Yeah, sorry, I’m fine.”

Raising my gaze to avoid suspicion, I see Mom looking slightly puzzled. I knew she had a great figure, and I expected her chest to stand out a bit, but seeing it now keeps my heart racing.

Her charm, evident even through the towel, surpasses Yukari-san’s age. As a mother, I try to suppress those feelings.

But Yukari-san, beside her, is naturally captivating too. Despite having bathed naked together, her towel-wrapped body stirs me. Her chest size and slim waist—I can’t help recalling what’s hidden.

This is bad. It feels insanely erotic, and I’m getting excited. Emotions swirl. I lean forward, but if I entered the bath now, my state would be obvious.

“Okay, Shun-nii, I’ll start with your hair!”

Yuki’s declaration is a lifeline.

“Yeah, th-thanks, Yuki,” I reply, voice high, as she smiles and grabs the showerhead behind me.

“…Yukari-chan, I’ll wash your hair and such, okay?”

“Eh, you were serious about that?”

“Come on, I wouldn’t lie like that. With Yuki and Shun-kun washing, I’m the only one to do your back.”

“Th-That’s true, but…”

Their exchange behind me echoes clearly. Mom’s suggestion from the changing room is apparently happening.

“Shun-nii, let me know if it itches anywhere!”

I can’t focus only on them. Yuki, standing behind me, starts lathering my hair with bubbles.

It’s pleasant but thrilling. She’s close, and her body reflects in the mirror. Even hidden by a towel, the single layer of fabric consumes my thoughts.

“Shun-nii, try to keep bubbles out of your eyes, okay?”

Obliging her care to avoid shampoo in my eyes, I close them.

This reduces my awareness of her body, but her fingertips feel more vivid. Having my sister, a youthful beauty, do this feels sinfully indulgent.

“…Yukari-chan, your hair is so beautiful. Straight and glossy—I’m jealous.”

“I-I’m flattered… Sorry…”

“You don’t have to keep apologizing, hehe.”

Meanwhile, I faintly hear Mom and Yukari-san’s exchange. Mom washing Yukari-san’s hair must be a lovely sight, I imagine.

“Shun-nii, ready to rinse?”

Lost in Yuki’s touch and their conversation, her check-in comes. I reply, “Yeah, p-please,” and she grabs the showerhead again.

“…While your eyes were closed, I got a bit nervous, hehe.”

Her soft voice after rinsing, echoing likely to the back, embarrasses me. My flushed expression is clear in the mirror.

“Alright, back next!”

I need to understand her intent. Hurriedly, I remove the wrapped towel, bunch it, and cover my crotch. I’m briefly scared my gusoku was visible, but it should be fine.

“…Okay, that kinda surprised me.”

I was sure my half-erect chinpo was hidden, but her comment shakes that confidence slightly.

※

Having Yuki wash my back, though guilt-inducing, goes smoothly. I flinch when she uses her hands instead of a towel, but since it’s just my back, it’s safe.

If she washed my front, I’d have gotten hard easily. With Yukari-san’s back likely being washed too, I need to banish those thoughts. Imagining my girlfriend’s beautiful back could spiral into fantasies.

Now, with the towel rewrapped, I’m lathering Yuki’s hair. Earlier, I asked, “C-Can I wash your hair in return…?” and she was delighted.

“Haaa… Shun-nii, you’re really good…”

Her relieved voice makes me happy. Her softened expression in the mirror doesn’t seem like flattery.

With her towel on, I can control my emotions. I focus solely on not damaging her beautiful long hair.

But that focus falters. After washing and rinsing her hair, I realize it’s time to wash her back.

“Thanks for washing so carefully, Shun-nii!”

Even after thanking me, Yuki keeps looking at me, briefly glancing at her chest.

“…Shun-nii, what about my back? Should I wash it myself?”

I wonder if she hopes I’ll wash her back, like she did mine. It might be wishful thinking.

“…If it’s okay with you, I’d like to wash it, but if you don’t want—”

“No way I wouldn’t want it!”

Her gaze, crushing my anxiety, is adorable and direct.

“…Then I’ll do your back, okay?”

When I nod, Yuki peels off her towel, covering only from her crotch to thighs. She could’ve exposed just her back, but she doesn’t.

“…I’ll wash it, Yuki.”

“Thanks, Shun-nii, go for it! ♡”

Matching her brightness, I try to stay composed, applying body soap and reaching out.

Composure is impossible, obviously. Her nipple tips flicker into view, and her small butt, slightly flattened on the stool, is fully visible.

“Ehehe, Shun-nii… ♡”

Rubbing her arms, shoulders, and waist, my gaze wanders. With such an undeniably sexual figure, this situation is tough.

Would Mom or Yukari-san disapprove? Are they even aware? I worry, but I should focus on Yuki’s body, though I lack the courage to look back.

Somehow lathering up to the border of her waist and butt, I check with Yuki and grab the showerhead. My weak chinpo is fully erect, but the tightly wrapped towel should hide it unless someone’s close.

“…Shun-nii, that felt so good! ♡”

Yuki’s grinning turn is unbearably cute. My hope that she doesn’t notice my erection might’ve shown on my face.

Washing Yuki off ends our sibling bonding. Even while rinsing, her pink nipples and budding breasts are visible, keeping my heart in turmoil. Yet she doesn’t try to hide.

At that moment, a “Phew” comes from behind. Turning finally, I see Mom, towel tightly wrapped, standing there.

“…I was curious how it’d go, but I was a bit surprised. Well, if you’re that close, it’s probably fine.”

Her words—“surprised” and “that close”—lead to one conclusion.

“…Yuki-sama, you’re bold…”

Clearly, they saw me washing Yuki’s back. That fact plunges me into anxiety.

But they don’t blame me for prompting Yuki to go topless. Mom mutters, “And Shun-kun’s just looking at us normally,” and Yukari-san agrees, “Y-Yes, right…”

“Plus, Shun-kun’s doing it so confidently, even if carefully.”

Mom’s assessment feels overly generous. But I can’t argue, partly because I’m staring at two beautiful women in towels.

“Fufu, Shun-nii’s an amazing guy! That’s why I love him! ♡”

Yuki pours out her affection shamelessly, leaving no room to protest my lack of confidence.

“…Honestly. But let’s get in the bath before it cools.”

From here, it’s time for all four of us to soak together.

“Oh, I haven’t washed my front! You three go ahead!”

“Yuki, no need to rush. We have time.”

Telling Yuki that, Mom looks at me, sighs softly, and leads us to the tub. I step over the edge as prompted, sinking shoulder-deep into the slightly hot water.
