After dinner, the women go to take their baths.

With nine women in our party now, we’re getting pretty big; it might be a good idea to consider expanding the tub space soon.

Once the women finished bathing, it was my turn.

It would be a lie to say I didn’t feel a little bit of loneliness at the prospect of bathing alone……

That’s not because I wanted to bathe with the other guys or anything.

The girls who shared a morning with me used to join me in the bath to wash off, but this was different……

"T-Takano-kun……?"

It was just as I finished washing my hair using the shower head we’d hauled back from the bonus area.

With that voice came the sound of the door connecting the changing room to the bath swinging open.

I turned to look and found Professor Luminas standing there, wrapped in nothing but a towel.

"P-Professor……?"

Frozen solid by the sheer shock, I couldn’t move.

Her face was flushed bright red, like boiled shrimp.

"A-alright, um... this is to say thank you for today and apologize for putting you in danger due to my own circumstances, so... i-if it’s alright, I thought maybe I’d wash your back……"

In her attempt to cover up her chest, the professor only served to emphasize just how ample it was.

“Of course, I’ll stop if I’m being a nuisance to you, Tanooki-kun! But if you’re saying something like ‘don’t force yourself, old lady,’ then that’s perfectly fine with me!”

Watching her speak quickly through teary eyes, I blurted out on the spot.

“A nuisance? No way... um... in that case, could I please ask you to?”

“...! Y-Yes. Please leave it up to me.”

And so, we moved over a little.

I brought the bath chair to the side of the tub and positioned myself so she could pour water on me from the bucket right away.

“Um... well then, please begin.”

“P-Please excuse me as I start.”

I turned my back to Sensei and sat down on the bath chair.

Sensei picked up the soap I had placed there.

Sensei Lumines is a beautiful woman with yellowish-brown hair.

She became a teacher right after graduating from university and currently serves as our class’s vice-homeroom teacher.

Perhaps because we were close in age, the girls treated her with a lot of affection, while I think some of the boys had started to take advantage of her.

There were even some guys who made comments that bordered on sexual harassment.

Her beauty, coupled with a bust size so shocking it surpassed even Chiyu's, pinned the eyes of many young men in place. Indeed, many male faculty members included.

And now, that woman was kneeling behind me, clad in nothing but a single towel.

"Th-then... I'll wash you..."

In an instant, a shockwave ran up my spine.

Slop... squelch.

The softness upon first contact, and the shift in texture as that object changed shape.

Before I could deduce what they actually were, these sensations delivered pure happiness to my brain.

Breasts.

The teacher had lathered her own breasts with soap, using them as a body sponge, rubbing them against my back.

"Mnn... ah... t-this isn't just unprofessional for a teacher... but then again, we aren't on Earth... K-Kudo-kun, you're glad about this... right?"

It was probably some trick Chiyu had put her up to.

But if I denied it here, the teacher would get hurt. Even without that, she might stop what she was doing.

So, I nodded forcefully.

"Yes, I'm happy."

And I nodded repeatedly. It was a magnificent, decisive nod.

"R-really? ...If it serves as both a thank-you and an apology... then... mnh-ssh... nnn..."

The teacher's breast-sponges rubbed up and down, and regardless of my will, the rod between my legs reacted.

"Well... next up is... uh, washing your arm?"

For some reason, Luminas-sensei trapped my arm in the valley of her cleavage and moved it up and down to wash it.

What an outrageous and lewd act for a teacher to perform on a student.

And naturally, with things like that, she'd end up right beside me.

Consequently, the area between my legs was inevitably within sight.

"Ah..."

Sensei froze in place.

After that, how much time had passed?

I felt enough time had elapsed for my body to start cooling down a bit.

Sensei swallowed hard, making her throat click audibly.

"S-so over there too... shall I wash it?"

Being asked such a thing while looking at me from under lowered lashes made holding onto my sanity impossible.

Before I could respond, my shaft twitched with a shudder, giving the answer away.

"U-understood... um, Kudo-kun."

The teacher froze just as she was about to take my dick in her hand.

"Um, I have a request..."

"W-what is it?"

Being kept on the edge like this was a mix of excitement and frustration.

"That... right now, could you just call me by my name, Luminas? Not as student and teacher... j-just as a pair of men and women..."

Perhaps that was the bare minimum ritual required for her to proceed with what she intended.

"Got it, Luminas."

When I called her name, her face flushed red in an instant.

"Nnnn. In that case, allow me to be equally forward then... 'Sou-chan'?"

I was struck by the surprise just as much.

I’d seen stories plenty of times about a boy being called with a childish suffix by an older sister figure, but...

Actually finding myself in that position felt strange.

It was a ticklish sort of feeling, mixed with pleasure.

"Well then... Sou-chan, I’m going to go a-go and rub you up now, okay?"

Teacher Luminas touched my dick with trembling hands, stroking it upward.

"Incredible… so hot… and it’s… so hard… and big…"

The intoxication in Teacher Luminas's voice stirred my sense of superiority, and as the pleasure from the stroking compounded with that feeling, my arousal climbed rapidly.

It was Teacher Luminas, a stunning teacher who any boy hitting puberty would definitely cast into his nighttime fantasies at least once.

The fact that she was desperately handling my cock right now amplified the pleasure manifold.

The lewd sounds echoing in the bathroom, the teacher's breathless moans, her body glimpsed through the towel.

"Luminas…! It’s almost time"

It seemed she understood immediately. "Mm. Okay, Sō-chan. Come when you’re ready," she said with a gentle smile.

"Guh…"

The moment of ejaculation.

Teacher Luminas leaned her lips close to my ear and mimicked the onomatopoeia in time with the forceful spurting of the white fluid.

"Kyah… psh, pshh-pshh, pshh-pshh… w-wow… it really does come out like a geyser… ah, psh-psh-psh… i-is this much coming out…?"

By the time my cock had been stained pure white up to her wrists, I had finished emptying everything.

"H-How was it? This was… our first time, so I was wondering if you managed okay?"

It was adorable how anxiously she asked, and my cock had already regained its hardness.

"W-Whoa, you've got some serious stamina... I'd love to go one more round, but... no can do today."

Professor Luminas spoke in a soothing, mentoring tone.

"Sou-chan is such a popular person. You don't exactly have time to give me all your attention, right?"

She was probably referring to the time he was scheduled to spend with Yorina later.

Professor brought her lips back to his ear again.

"Maybe on another occasion...?"

I stifled the urge to ask right away and nodded, "Yes."

"Mm. Good boy, good boy."

"Good boy, good boy," she said with a smile. Her face seemed equally suffused with affection and excitement.

It's tough when you're dealing with such complex dynamics, though.

The frequency of these complex dynamic scenes has been increasing lately...

Only 6 days left until the book release!!!

After dinner, the women go to take a bath.

With nine women in the household, it might be time to consider expanding the bathtub.

Once the women are done, it's my turn.

If I say I don't feel a bit lonely bathing alone, I'd be lying...

I don't particularly want to bathe with the other guys.

I do bathe together with the girls I've greeted in the morning, for the purpose of washing off the dirt...

Just as I finished washing my hair with the shower brought back from the bonus area...

A voice accompanied by the opening of the door that connects the changing room to the bath.

Looking over, there was Ms. Lumina, wrapped only in a towel. "K-Kino-kun...?" The shock was so great that I froze.

Ms. Lumina's face was as red as if she had been boiled.

"U-Um, that is... As a thank you for today, and as an apology for putting you in danger due to my own circumstances, I thought I'd... wash your back for you..."

She's covering her chest in a way that actually emphasizes her ample bosom.

「Of course, if it's bothering you, Koharu-kun, then I'll stop! If you say 'Don't push yourself, Auntie,' then I'll definitely stop!」

Seeing her plead with tear-filled eyes, I quickly opened my mouth.

"It's not bothering me at all...! Um... Then, can I ask you to do it?"

"......! Y-Yes. Please leave it to me."

So, we moved a bit.

We brought the bath chair to the side of the tub, and she prepared the bucket of water so she could pour it over me right away.

"Um... Then, please do it." "Then, I'll get started."

I turned my back to the teacher and sat on the bath chair.

She picked up the soap I had set out.

Luminas-sensei is a beautiful woman with yellowish-brown hair.

She became a teacher right after graduating from university and was our class's vice homeroom teacher.

Because she was close in age, the girls seemed to like her, but some of the boys seemed to take advantage of her.

There were even some guys making lewd comments.

Her beauty and the astonishing bust size that surpassed even Senyuu's, had captured the gazes of many boys. Not just boys, but male teachers too.

That woman is now kneeling behind me, wearing nothing but a towel.

"Th-Then... I'll wash you..." At that moment, a shock ran through my back. Fu... Nyon.

The softness when she touched me, and the change in sensation as the object shifted shape.

Before I could identify what it was, those sensations brought me immense pleasure. Her breasts.

The teacher had smeared soap all over her own breasts, treating them like a body sponge, and was rubbing them against my back.

"Mm... Uu... This is far worse than just being unfit to be a teacher... But, this isn't Earth... So... K-Kino-kun, you're happy... with this, right?" Probably Senyuu's idea.

But, if I denied it, the teacher would be hurt. And even if she wasn't, she might stop what she was doing. So, I nodded firmly. "Yes, I'm happy."

I nodded several times, with a confident air about it.

"I-Is that so...? If this is an apology... Then... Nnsho... Nn... Nn..."

Her chest sponges rubbed up and down, and my crotch reacted involuntarily.

「Um... the next thing... I should wash my arm, right?」

Luminas-sensei actually washed my arm by sandwiching it between her breasts and moving it up and down.

What a radical and lewd act for a teacher to do to a student.

And as a result, sensei came to stand next to me.

Naturally, my crotch came into view. 「Ah...」 Sensei froze.

How much time had passed, I wonder.

It felt like enough time had passed for my body to get a little cold.

Sensei swallowed hard.

「S-Should I... wash that too?」

She asked with a sidelong glance, and I couldn't keep my sanity.

My dick twitched before me.

「O-Okay... um, Kouno-kun」

The teacher stopped just before grabbing my shaft.

"Um, I have a request..." "W-what is it?"

It was exciting and frustrating, being teased like this.

"Um... Could you just call me Lumina? Not as teacher and student... but as a couple?"

This might be the minimum ritual the teacher needs to proceed with the act. "Okay, Lumina."

When I called her name, her face turned red.

"U-Um, then I'll just call you... 'Sousan'?" I was shocked too.

In stories, it's common to see a young boy being called by a suffix by an older sister figure...

But actually being in that position felt strange.

It was ticklish and sweet.

"Then... I'll go ahead and... start working on you, Sousan?"

Lumina teacher touched my shaft hesitantly and started stroking it.

「Amazing... It's so hot... And it's... hard and... big...」

The dazed voice of Ms. Lumina, mixed with the pleasure of the rod, made my excitement rise higher and higher.

Ms. Lumina, the beautiful teacher who would definitely appear in the dreams of any teenage boy.

The fact that she was currently working hard on my rod was amplifying the pleasure by several times.

The lewd sounds in the bathroom, the teacher's breathing, the outline of her body through the towel.

「Lumina...! Soon...」

She seemed to have understood and smiled gently, saying, "Yes, So-chan. You can release it whenever you want." At the moment of ejaculation.

Ms. Lumina brought her lips to my ear and, in time with the spurting of the white fluid, she made the sound effects.

「Kyaa... Byu, byuu, byuu, byuu... It's... really like a geyser... Ah, byuu byuu byuu... Is it... really coming out this much...?」

When she had stained her wrists white, I had finished releasing everything.

「How... was it? I mean... It was your first time, so did you do well?」

She asked anxiously, and I was already hardening again.

「S-Such amazing recovery... I really want to do it again... but not today.」

Luminas-sensei says it as if advising me.

「Souchan is popular. You don't have time to focus only on me, do you?」

Is she talking about the time she has with Serina after this?

Sensei brings her lips close to my ear again. 「M-Maybe another time...?」

I suppress the urge to beg her right away and nod. 「Yes. Be a good boy.」

Sensei smiles and her face seems to be half affection and half excitement. The wise scenes are getting harder...

The frequency of the wise scenes has been increasing lately...

Only 6 days until the book version is released!!!
