Chapter 30

It was supposed to be the most calming place.

Throughout its history, dating back to BC, it has been believed that this bath was the only place of rest that had been responsible for the peace of mankind.

"Miyu..."

Miyu sits on a chair and washes out her shampooed hair.

She looks glamorous as she lightly applies conditioner before letting it flow, her long hair gathering in front of her chest.

So much so that I forget we're a blood-related family, much less that she's younger than me.

At least, my body has already forgotten that Miyu is my little sister.

It's obvious from looking at this reproductive organ that it looks like it's about to push Miyu down and ejaculate sperm into her vagina.

One day, Miyu asked me, 'Do you want to make me pregnant?' and I denied it.

In fact, I have never wanted to have my little sister as my lover or wife.

Except in games though.

To this day, I've used Miyu as my fap material many times, but my ethics still shun incest.

In my mind, I reject having sex with my little sister.

Still, my instincts dominated my body to the point that I ignored my rationality.

"I-I...!"

I put my hands on the edge of the bathtub and stuck out my upper body.

I need to cool my boiled head.

Ethics isn't the only thing that should condemn having sex with my little sister.

It should be instinctive.

This conflict itself is something that I shouldn't have as an older brother, or rather, as a person.

If someone like me is near Miyu, it'll be dangerous for her.

The bathroom is a dangerous place.

Everybody gets naked here.

The true nature of a living thing.

My instincts are already becoming fully active.

I can't restrain myself with reason anymore.

"I'll be leaving now--"

As I was about to finish, it was Miyu who stopped my opportunity to speak.

"Did something happen?"

Miyu tilts her head slightly while soaking the sponge with body soap.

"It would be nice if you can wash my body as well."

Gush, gush, the sponge foams up.

It was the devil's whisper.

In place of the evil within me, Miyu stirs up my sexual instincts.

"Ah, eh."

Doubt, confusion, suspicion.

Miyu's enchanting body blows away all those elements.

"L-let's see. Your back too..."

Without even trying to hide my erect penis, I got out of the bathtub and went behind Miyu.

That water-repellent, fine-textured skin of hers draws my gaze.

Of course, she takes care of herself every day, but Miyu's beautiful white color is simply due to her reclusive nature.

I've never seen her tan even in the summer.

Compared to her short stature, she has well-built muscles and naturally long legs.

She even told me, 'If you want a girlfriend, you should work out.'

Miyu has also trained quite a bit.

Youth isn't the only thing that makes her two fruits grow so well.

I can clearly see Miyu's excellent posture while sitting on the chair just by looking at her from behind.

"Yes, here's the sponge. I'll leave my whole body to you, okay. If you touch me with your hands, I'll get angry."

Miyu turned around, handed me the sponge, and gave me a piercing look.

Her black hair dripping with water.

I swallow my saliva.

I had a certain excitment that I didn't feel when we were soaking in the hot water together.

I carefully remove the dirt with foam to avoid losing it.

I wonder why I'm doing this.

That's what I thought in my head.

I was intending on running away.

Before I knew it, I was obeying her orders.

It doesn't matter if she has a favour for me or if I'm indebted to her.

No matter how hard I try, I can't go against Miyu.

And this sexual desire too.

I'm going crazy.

If I could just reach out and touch her with my hands.

That warmth, that softness, if I hold it, I'm sure I'll ejaculate just from that alone.

I slide the sponge down her arms, then wash her back, moving from her hips to her stomach, then to her thighs.

"W-what about your chest?"

"I hope you can do the same."

"Even if you say the same, come on. Your cleavage and tip. I have to clean that too, right?"

The part of the chest that collects the most sweat cannot be washed without removing that large lump of flesh.

I had been warned not to touch her with my hands, so there was nothing I could do about it.

"Will this be okay then?"

With her own hands, Miyu spread her boobs to the left and right, leaving a gap for the sponge to enter.

Twitching and twitching, my cock reacts accordingly.

I know how much you want to be sandwiched by that thing, but for now, calm down, my son.

I can't afford to indulge in such delusions.

"About the latter, don't hit it with the sponge, okay."

Additional conditions announced by Miyu.

Miyu ordered me not to stimulate her nipples even if I used the sponge.

The established theory in 2D is that small breasts are sensitive and large breasts are insensitive.

It shouldn't be a big deal if the sponge just scratches it, but.

The reason why she ordered me not to hit it with the sponge even though I was being so cautious was because there was a risk that she would feel it just by touching it, at least that's what I think.

Could it be that place is developing?

After growing so big, has she become hypersensitive to sexual sensations?

"A-all right..."

This is no longer disciplinary training for me.

I practise the way of Zen, emptying my mind.

Although it is impossible to remain mindless, I try to force my brain to not understand my own thoughts.

I turn slightly to the right, reach out from the side of her shoulder, and wash her chest.

Carefully, rubbing only with foam, not looking at her boobs so as to not make my breathing heavy.

"Next, do my legs."

Miyu straightens her knees, pulls out a chair, and instructs me to move forward.

Miyu doesn't pay any attention to me, even though my curved shape that looks like it's going to stick to my stomach comes into view.

I apply foam from Miyu's knees to her calves.

Also to her toes stretched out like a ballerina.

I feel like a slave.

A servant who obeys their queen's orders.

If I am ordered to lick it, I will happily do so.

Just like a dog.

-I mean, I actually want to lick it.

The spaces between her fingers, the top of her breasts, and her important parts that I hadn't washed yet that were wet enough to stain my pants.

"Uguh... Mi-Miyu! It's over...!"

I shake my head strongly to drive away my impure thoughts.

Miyu's body is full of foam.

Every part of her body is slimy.

Just by pressing on her hips, I feel I would cum anywhere.

Ahh, I'm already done for.

All I can think about is having sex with Miyu.

"It's over? Doesn't Onii-chan always wash his butt and between his thighs?"

"I wash them, but..."

"Then it's not over yet, is it?"

Miyu got up from her chair and knelt on the floor.

Spreading her legs and leaning forward slightly.

She raises her upper body after getting on all fours.

A beautiful curvaceous back.

Moderately fleshy buttocks and legs.

She once again instructed me to get behind her and glared at me, telling me to hurry up.

In this position, if I get on my knees, I can reach her back.

Then, if I firmly grab Miyu's waist with both hands and screw my vein-bearing penis in her, I will ejaculate before even thrusting three times.

"... ah... haah..."

I can't control my heart palpitations.

My head goes completely white.

"Miyu... i... is it fine... if I insert it...?"

My eyes in the mirror were bloodshot.

Seducing me like this.

Does she want to have sex with her older brother that much?

It's fine by me, I don't care what she does.

It's summer vacation.

Our parents aren't here either.

We can have sex every day from morning to night.

I want to have sex with Miyu.

I want to give this little sister of mine a creampie.

"I don't think it's a good idea."

Miyu replied in a low voice.

Then let me at least masturbate.

It should feel so good that I'll lose consciousness just by spraying semen on her from behind in this position.

"Hurry."

Obsessed with Miyu, my body listens to the instructions and washes the Miyu's body, my thoughts completely disorganised.

From her inner thighs to her buttocks and then to her important parts in between.

I tuck my arms under her crotch.

I'm just touching it with foam.

I can't strongly stimulate her female genitals.

It's fine as long as it feels refreshing after she rinses it off with hot water.

In my hazy consciousness, I bubble up on her butthole, too.

I washed it.

There was plenty of nectar left over from Miyu.

Miyu washes it off in the shower.

Hot water and foam, flowing down from her limbs.

A solution containing plenty of Miyu's extract.

If it's now before it goes down the drain, and if it's the hot water right after rinsing Miyu's body.

It would still contain plenty of Miyu's ingredients.

If I drink it, I'm sure it would increase my semen more than maca or zinc.

Damn it, why do I keep thinking such stupid things?

I'm not even thinking of human things anymore.

"Aah......"

All I could do was watch the bubbles being mercilessly washed away.

My sexual desire and reason were fighting each other, and that was all I could manage.

"Thanks."

Miyu thanked me and entered the bath.

I'm through.

Let's get out of here.

Let's go back to my room and masturbate.

"Onii-chan, are you leaving already?"

Miyu asked me an incomprehensible question when I unlocked the bathroom door.

Even though she snuck in without permission and interfered with other people's bathing and even their masturbation.

"I'm leaving first to relax in my room."

I can't bear to be interrupted any more while masturbating.

I'd wipe myself dry, dry my hair, lie on the bed, and love this cock as much as I like.

I want to masturbate soon.

I want to ejaculate soon.

I closed the bathroom door and reached for the towel.

The relief that comes.

My ability to think revives.

--Was this really okay?

Miyu is calling me to the bath.

The question is the meaning of that.

Miyu takes a bath with me.

She spends time naked with me in the same space.

When such a reward is dangled right in front of me, why don't I take it?

Sure, this could be a trap.

If I go back to the bath now, I'm sure I won't be able to ejaculate again.

But, then what?

Once I've ejaculated, it's over.

I'll just feel refreshed, that's all.

There's nothing left.

Should that be prioritised over taking a bath with Miyu?

No.

Absolutely not.

"...My body's cold. I guess I should go in after all."

I opened the bathroom door.

"Is that so."

When Miyu hears my words, she folds her knees and creates space in front of her.

It seems to mean I should get in there.

I folded in the same way and entered the bath.

A bathtub overflowing with hot water.

As expected, the place is too small for two people to fit in.

"Um, can I ask you something?"

I was just going along with whatever was happening.

I already know that this is not normal.

"What?"

"It feels to me you're a lot more aggressive today. If it's not just my imagination."

It's strange that Miyu's skinship is so excessive.

Even the old Miyu was never this attached to me.

"Well, I guess it's not your imagination."

Miyu answers while fixing her hair tied up with a clip.

"Is there a reason?"

When I asked that, Miyu's expression changed blatantly.

"Hmm. Yeah."

Miyu narrows her eyes and stares at me.

"As I thought, it was like that."

Miyu's response was vague.

If only I knew.

She has no intention of telling me if I don't know.

Such a response.

She sat on my lap, gave me her stained panties, and took a bath with me.

What is the reason for giving me such rewards?

"Do you want more?"

My heart and cock react to Miyu's words.

It's hardly surprising that she's able to read my mind by now.

'Do you want more.' Those kinds of words, Miyu just said.

"Onii-chan's a good-for-nothing person who doesn't have any doubts about lusting for his little sister."

The colour of skin moves under the water.

Miyu's legs stretch between my crotch.

"Ah...!"

My most important part as a man was casually being trampled on.

I was trembling with joy as she stepped on my back muscles firmly.

"Miyu, that's not... aahhh...!"

My cock, which was already on the verge of exploding, was being twisted around by Miyu's small feet.

It was so strong that it hurt, from the root to the glans.

She was stepping it in a messy way.

I don't think she's trying to make it feel good using her feet.

It's just an act to disparage and degrade me.

My joy rises above my pleasure.

Even though I'm not supposed to be a masochist.

I can't help but rejoice that I'm being abused by Miyu.

"You really have an honest body."

Miyu's foot movements change.

As the arches of her feet move away, she instead presses my cock with the balls of her feet.

The next thing I touched was Miyu's toes.

To my upwards-facing cock, she pushes it to the side and from the top pressing it down.

She toyed with it, and in the end, caught my rod between her toes.

Opening her big toe and index toe, she tickled the back of my glans with just a single groove. It almost felt like vaginal folds or love juice, even though it wasn't.

The petite Miyu could only hold my fully erect cock between her toes half the time, but.

That was enough.

Rubbing my back muscles with her toes.

"Aaahhh... ahhh!!"

Miyu's feet are squeezing my cock.

The quality of the pleasure was clearly different from when she did it by hand.

In addition to the physical pleasure, the shame of being trampled makes my body hot.

Shit, I might prefer this actually.

"Haah, haah, aaahhhh... Miyu, it feels so good... ahhhh-... ah, ahhh!"

"You're moaning too much. You sound like a girl. If you make that sound in such an echoing place, I'm sure it can be heard all the way to the living room."

While blaming me, Miyu doesn't try to stop moving her legs.

I don't care anymore.

I didn't care who heard me as long as it felt good.

"It's a relief our parents aren't here, right?"

Behind Miyu's expressionless face, a smile of amusement and her bewitching face lurks.

The moment I saw it, I understood.

I guess I'll never ejaculate on anyone other than Miyu for the rest of my life.

It's up to Miyu whether she'll let me cum like this or not.

"Mi-Miyu, I'm already cu-... cum-... cumming-...!!"

Miyu suddenly lets go of her legs as my cock pulsates, expanding and contracting.

"Ahh! Mi-Miyu, that's not... I'm already...!!"

It's impossible to hold back ejaculation.

I don't cum on Miyu, it can't be contained anymore.

"Miyu...!"

My body moved on its own, covering Miyu.

I hold one of Miyu's legs and push the other away with my knee.

My cock, about to ejaculate, is thrust onto her secret place, forcing it open.

"Onii-chan, you can't."

Miyu calmly admonished me.

I know I can't.

And what's more, she's my real little sister.

She's a girl younger than me who hasn't had any experience with men yet.

There's no way creampie-ing her is acceptable.

"Miyu... I-I'm inserting it... I'm inserting it, okay."

I pushed it firmly into the crack.

My glans, sensitive and engorged with blood, could feel it.

It was slippery to the touch. There was no doubt about it.

"You're... wet...!?"

Even after washing it.

Miyu's vagina is still so full of love juice.

"You can't insert it in, you know."

"Miyu, I understand. It was Miyu who wanted this."

"Onii-chan, listen to me."

"It's so wet. Miyu was excited to touch my stuff too, right?"

Otherwise, this situation cannot be explained.

Miyu wanted me to attack her.

By simply seducing me like this.

Because it's in her nature to not talk about it.

She destroyed my rationality to the limit and forced me to rape her.

"Onii-chan."

Her words clearly reached my ears.

Miyu's face is clearly visible.

She wasn't crying nor angry.

The same expression as before.

Miyu and I stare at each other, with only our entrances intersecting.

"...Today is a dangerous day."

Miyu gently puts her hand on my cock.

"Onii-chan's semen is thick. I'll probably get fertilised."

Her hand ran down my rod, and Miyu gently stroked her lower abdomen.

"...I don't want to get pregnant yet."

Miyu did not resist fiercely.

Even if she isn't violent, she probably knows that I won't anything after all that.

In this overlap of nakedness, the distance between our hearts is not as close as it seems.

The only sound in the room was heavy breathing.

I weakly pulled my hips away, as I was about to insert my cock into Miyu's crack.

"Nn, thanks."

Miyu said disproportionate words in response to my outrage, and curled up in a ball, hugging her knees.

I couldn't do it.

Inserting it, as well as asking for it.

When Miyu told me that today was a dangerous day, the urge to cum inside her grew in my heart.

Even if the other person is their lover, people will usually hesitate to insert it in if there is a hint that there is a risk of pregnancy.

Even though I didn't have the desire to impregnate other girls.

More than anything, why did I want to cum inside my little sister on such a dangerous day?

"Is it time to leave already?"

I wanted to reply to Miyu's suggestion that I would like to stay and let off steam.

In the end, I couldn't resist Miyu, who still ordered me to dry her hair after doing such a thing.

"Haah..."

I lie sprawled out on the bed.

The ceiling is far away.

I want to masturbate.

But I don't want to masturbate.

Such conflicting immoral passions swirl around.

I didn't want to quell this pimple that had finally reached my stomach with just masturbation.

Even if I came, Miyu wouldn't drink it.

Even though I had accumulated so much semen.

I want her to drink it.

If I were to express my desires, I wish for her to hold it in her mouth.

If I were to ejaculate while Miyu was giving me a blowjob, there would probably be more semen than could fit in Miyu's mouth.

I want to force it into the back of her throat and watch Miyu gulp.

The desire grows stronger and stronger.

As I thought, I can't just masturbate.

Let's at least use an onahole.

I haven't used it in a while, so it feels kinda special.

There was a set of an onahole and lotion left in the drawer.

I spread a towel on the bed, put my onahole on top of it, and poured the lotion on it.

It's best to warm it up before enjoying it, but I can't wait any longer.

The memory of inserting it into Miyu's vaginal opening in the bathroom comes back to me.

My penis was so vigorous that the the sound of twitching in mangas would be appropriate to describe it.

I take off my pants and underwear and jump on my onahole as if attacking it.

"Haah... ah... uu... Mi... Miyu...!"

When I lowered my hips and inserted the cock into my onahole, I could no longer suppress my sexual desire.

"Miyu... it feels good..."

When screwed in, it leaks honey.

Just like today's Miyu.

The rubber material is swollen.

The onahole was tougher than usual.

"Ah, aaahhh, Miyu... good...! So good...!"

The sound of the creaking bed brings to mind the scene of me actually having sex with Miyu.

Having sex with Miyu feels good.

I want to have sex with her for the rest of my life.

"Miyu, Miyu...!! Aah, inside, I'm cumming inside...!!"

Creampie-ing Miyu.

My wish finally came true.

"Onii-chan, shut up!"

Bang, the door was opened.

My hip movements stop.

Shit, I spoke too loudly.

She heard it all.

"Come on. What time do you think it is?"

An angry Miyu crosses her arms.

I'm sorry for being so noisy this late at night but.

It was about that?

"M-my bad."

"Hmph."

Miyu walked up to the side of the bed and squatted down.

With my penis inserted into my onahole, she observes my miserable lower body while I'm in missionary position.

"Is this me?"

Miyu poked the onahole with her index finger.

"I-I'm sorry!! For being this rude!! I'll throw it away right away!!"

"Ah, it's fine though."

I jumped out of bed.

Leaving behind Miyu, who I had tried to keep from going.

I threw my onahole into the trash can.

After washing the lotion that was all over my rod with hot water, I returned to my room.

Miyu sat on the floor waiting.

"It's really my apologies."

I simply apologised.

Even Miyu wouldn't feel good if she was treated like an onahole.

"Please be quiet next time."

Miyu didn't get mad at me for using the onahole in her place.

Since she was dealing with my semen with her mouth, I was practically treating her like an onahole, so it would have been a natural reaction after thinking so.

"So..."

Miyu doesn't move in front of my naked lower body, my penis that has not yet been freed from its erection.

"Was there... anything else?"

I pick my pants off the floor, sit on the edge of the bed, and hide my private parts.

In response to my question, Miyu picked the shoulders of her pajamas and pulled on them lightly.

"This."

"Yeah?"

"New pyjamas."

"R-right."

Eh, what?

That's it?

You're here to say that?

"How is it?"

She asks in a polite tone.

Miyu's pajamas were a set from a pair of shorts, made of a thin material similar to silk.

The slightly tinted pastel pink roundly shapes Miyu's huge breasts, which are supported by a night bra, as if shaped by knit fabric, albeit not quite to the same extent.

"I think it's cute. It suits you very well."

If I were to express my sincere opinion, I would say it's 'erotic' though.

"That's great to hear."

Miyu got up and left the room.

This pattern again.

Could it be that me making too much noise was just an excuse?

She's definitely trying to stop me from ejaculating on purpose.

I don't know why.

Being done in to this extent, it only makes me frustrated.

If I just masturbate and ejaculate immediately from here, I'd be able to destroy Miyu's plan, which I don't really understand.

But would that be enough?

My testicles are on the verge of bursting from being made to endure this much.

I won't feel any sense of superiority just by saying, 'I ejaculated without your permission.'

In that case, I will continue to be patient.

I won't masturbate until Miyu goes to sleep either.

A creampie was certainly not allowed.

I still don't have the ability to take responsibility for getting a girl pregnant.

But other than that, I can do most of the things I want to do.

I think so.

I had a mysterious belief that Miyu wouldn't get angry if I played some naughty pranks on her.

That's why I dare to stop myself from masturbating.

When Miyu is asleep, I insert my cock into her now defenseless mouth and ejaculate inside it.

A lot of semen comes out, so much so that Miyu can't contain it in her mouth.

Miyu probably hates getting her bed and clothes dirty, so she has no choice but to drink it.

No matter how much I ejaculate.

I can do this.

I get the feeling I can do this today.

I mean, isn't that right?

Miyu treats me calmly, even after I almost raped her.

That's why I can force her to drink it.

My semen.

I can't stop running ahead just by imagining it.

This is not the time to wear my underwear.

Let's remain undressed on the bed until Miyu falls asleep.

As long as I don't masturbate, Miyu can't interfere with me.

"Onii-chan."

The sound of a light knock on the door.

She came after all, huh.

But unfortunately.

My underwear is off, but I'm not masturbating.

That was a wasteful move.

I won.

I finally surpassed Miyu.

What excuse would Miyu come up with when she saw me not doing anything when she entered the room?

I'm looking forward to it.

"Are you sleeping already?"

She popped her head out of the door.

Miyu must be panicking inside.

"That's right. It's a little early, but I'm going to bed now. I have to leave the house in the morning tomorrow, so I want to get some rest now."

"Great. Then, don't mind if I come over, okay."

She stepped into my room and closed the door.

Miyu came up to me, holding the pillow she usually uses in her arms.

"--Hah...?"

Pillow?

Why do you have such a thing?

"Onii-chan, get back."

Miyu asked me to leave some space on the bed.

To have enough space for herself to sleep.

Preparing this bed.

"Eh? Eh? Eh?"

"Get out of the way."

"Yes."

At Miyu's urging, I gave up half of my bed.

Miyu placed a pillow there and climbed into the futon without hesitation.

"I'm not wearing any underwear though..."

"Yeah. I know."

Miyu moves her body closer to the middle of the bed.

Miyu knew that I had been masturbating since a while ago and hadn't ejaculated yet, so she should also know that my penis was in perfect condition.

Is this girl insane?

She did something similar in the bath earlier and almost got raped.

"Onii-chan."

"Ah, yes. What is it?"

I look up at those big eyes from a close distance.

Ahh, cute.

My little sister is the cutest.

"You know, right."

"Eh?"

Miyu pulls on her pajamas again as I look confused.

"These are new clothes. My favourite."

"Yes."

"If you get them dirty, I won't forgive you."

Miyu glares at me with stern eyes.

Then, wouldn't it be better if you just let me bust even a single time?

You don't have to drink it, I just want you to give me just a little time until I ejaculate.

Miyu closes the distance towards me even more.

In such a state, even if I was able to resist masturbation, I would have a wet dream and it would be miserable.

I don't even have underwear on.

Miyu's clothes will suffer the most damage.

When she wakes up in the morning, I'm sure her pajamas will be so soaked with semen that they'll change color.

Turn the other way, at least.

In that case, there would be less stimulation, and Miyu's clothes wouldn't get dirty even if I had a wet dream.

Unless I had a strange dream and attacked Miyu right next to me.

"Ah."

When I saw the small shelf at the head of the bed, I couldn't help but let out a voice.

The thing that came into my field of vision was the leftovers I used with Sachiko.

That small square-wrapped item fills me with insane curiosity.

"Mi-Miyu."

I turned over to the other side again and faced Miyu.

Her adorable eyes blink.

"There was something like this but..."

I held it with both fingers and showed it to Miyu.

Miyu blinks and freezes for a while, then picks it up in a nonchalant manner.

"It's a condom, isn't it?"

A thing used by men and women for contraceptive purposes when they have sex.

Or rather, that's the only use it has, and that's the only intention behind handing it over.

"Onii-chan."

Miyu looks at the condom carefully, then shifts her gaze to me.

"I wonder what you meant by giving this to me."

A question from Miyu.

I'm sure she knows the answer.

"That's, uh, about that. I want to d-do it... or how should I say it..."

"Yeah. I understand that. But why?"

I was confused by the question that followed, and when I understood the intent of it, I was taken aback.

I gave her the condom because I wanted to have sex with Miyu.

So, why do I want to have sex with Miyu?

Of course, it's because I want to release this pent-up sexual desire.

That's the only reason.

Due to my one-sided desires, I sought for my little sister's body.

I like Miyu and respect her as a woman.

That was my intention, but this is the same as before.

It's no different from that selfish masturbation where I pretended my onahole to be Miyu and shook my hips.

"S-sorry."

"Why are you apologising? Tell me in words."

There was no anger in Miyu's tone.

Is she hiding it so deep that I can't see it, or is she so stunned she didn't get angry?

Either way, there was only one thing I had to do.

"I wanted to... do it with Miyu. I was pent-up after all. If I came in Miyu, I thought it would feel good. For me..."

No matter how perverted my desires were, I had no intention of hurting her.

The same thing happened when I nearly attacked her in the bathroom.

I should be grateful to Miyu, but I'm always just expressing my sexual desires.

Even if I was forbidden to ejaculate and provoked, I had to respect her dignity as a girl.

"Hmm. Well, if that's the case, it's fine though."

Miyu pushes the condom back onto my chest.

"I won't do anything naughty. I'm your little sister."

"Eh? Ah, yeah. That's right."

Wait what?

Was I somehow forgiven?

Even though not only did I use my onahole as Miyu, but I also treated Miyu as an onahole?

"Where's the remote control? Turn off the light."

At Miyu's urging, I turn off the light in the room.

In the dark, in bed with my little sister.

Miyu pulled my arm and shrank herself in, clinging tightly to my chest.

C-cute.

She smells good.

But why does this flow bring us closer together?

I don't know.

I don't know, but she's cute.

"Miyu, I'd like you to at least let me wear some underwear..."

Miyu's leg was resting on my inner thigh.

I can't move like this.

If I sleep with my lower body exposed, I'll definitely have a wet dream and cum all over her pyjamas.

An incredible amount, at that.

"Miyu?"

Before I knew it, I could hear Miyu sleeping peacefully.

I thought she was pretending to be asleep, so I poked her in the chest a little to threaten her, but she didn't respond.

Even when I inserted my finger through the buttoned-up gap, the sleeping beauty didn't wake up.

Even though she definitely disliked having her breasts touched, she didn't move an inch.

Did Miyu always fall asleep this easily?

I didn't know that.

Well, siblings don't sleep together, so it's only natural that I didn't know about it.

"Nnh... something about this..."

When I hold Miyu's head in my arms, I feel very calm.

The sexual desire that had been surging through me like a raging wave just now seemed like a lie.

The smell of freshly shampooed hair.

Usually I'd get aroused.

Right now, it only warms my heart.

I'm getting sleepy.

Even though the one below me is still so full of energy.

My eyelids are heavy.

Miyu.

She smells so good...

"--Fuah... nn-."

The next time I opened my eyes, the morning sun was stimulating my eyelids.

I fell asleep easily.

Even though I was so excited.

Miyu is still sleeping in my arms.

Her long eyelashes and smooth nose.

Yeah, this figure is that of a beautiful girl after all.

...Aren't I incredibly lucky right now?

"Nh... huah...? It's Onii-chan..."

The princess finally woke up, her eyes still hollow from sleep.

"Good morning."

"Good mornin..."

Miyu grabs my clothes and rubs her cheek against me.

Is this really Miyu?

I wonder if the person inside that body has been replaced with someone else.

"Hmm... Onii-chan... why are you in my bed..."

"It's my bed. Miyu really has a hard time waking up, huh."

"Fueh?"

Miyu raised her head and looked around.

It was a room that Miyu was unfamiliar with.

The futon was a different coloru and there were no cushions.

"Haa--Oh no!!"

Miyu quickly flips over the futon and gets up.

The first thing Miyu saw when she woke up was my cock.

What does that mean for you as a girl?

"...You haven't came?"

"Fortunately. I was sleeping so soundly that I didn't have any chance of having any strange dreams. I didn't get around to busting anything out either."

"I see. That's great. Well, I'm not going to forgive you for that, though."

Miyu kicked the futon to her feet and rode on my still exposed lower body.

Narrowed eyes.

This time, I feel anger.

"Eh, did I do something!?"

"That's right. You're acting as if you had nothing to do with it. All this time."

No no no, please be more easy to understand than angry.

Making me endure ejaculation with such erotic temptations is like a punishment for you, but for me, it's more like a reward, isn't it?

"Hey, Onii-chan."

Miyu puts one hand next to me and strokes my chest with the other.

Her gravity accentuated boobs are destructively erotic.

"When you fondled my breasts, you said you'd do anything to apologise."

The night before yesterday, Miyu was in bed thinking about the results of her medical checkup, and I took advantage of her trouble waking up, rubbing her breasts.

For Miyu, who has a complex about her breasts being too big, this must have been even more unacceptable than having her private parts touched.

"Are you angry about that?"

"I'm angry about that too."

Did I do something else?

But this time, no matter how much I dig through my memories, I can't remember anything.

"Hey, Onii-chan. When you said, you would 'do anything,' that wasn't a lie, right?"

"O-of course! I'll do whatever Miyu wants!"

As expected, I wouldn't be able to bear it if she ordered me to die, but Miyu isn't the kind of person who would say such a thing.

"Onii-chan has been helped many times by me."

"Yes, that's exactly right."

"You've made me angry many times."

"There is no doubt that that's true."

"I think it's about time you feel bad about not being able to return the favour nor apologise."

"There's no denying it at all..."

If Miyu tells me to do anything, I'll do anything.

That's about all she did for me.

There's no way it can't be done.

"Onii-chan, you understand the meaning of 'do anything,' right?"

Miyu brought her face closer and pressed her index finger firmly into the center of my sternum.

"No matter what, right? You will never disobey any order I give you. You will gladly obey it. I will not allow you to talk back. I will not allow you to ask questions. And I will not allow you to refuse, not even for the rest of your life."

Miyu's voice becomes more terrifying.

My instinct as a creature was telling me.

I thought, 'This is kind of dangerous.'

I should resist.

No matter how much I owe her in the past.

Don't promise only this.

This is my final retreat.

I can still turn it around a bit here.

Conditions can be relaxed.

"Ahh..."

Say something back.

It is definitely wrong to just accept what you are told.

"Onii-chan, this is my final confirmation. For two days from today, you will have to follow my orders. No matter how unpleasant it may be. No matter how dangerous it is. Silent slave, you will absolutely obey."

No good.

Say no.

A yes on a no is just a concession, a conditional agreement.

If I accept here, I can't go back.

That includes my path as a person.

"If you break your promise, I will never accept any favours from Onii-chan ever again."

It stung hard.

From now on, I won't be able to rely on Miyu for the rest of my life.

Such a life would be hell.

I'm sure that even now, Miyu is talking on the premise that I shake my head vertically.

That's why I had to manage my ejaculation until yesterday.

"Okay. I promise."

That's why I said it.

I let it out of my mouth.

I will definitely repay Miyu's unexplainable anger and the hope that was born from it.

"As expected of you, Onii-chan. That's a very good response."

Satisfied, Miyu smiled slightly, got off the bed, and put her hand on the doorknob.

"First order. For two days, you are not allowed to ejaculate until I tell you it's okay. Wet dreams are out of the question. It's a self-reporting system, but I'll know if you lie."

Miyu opens the door and steps out into the hallway before turning her head back.

"Please come back tomorrow at 6 p.m. sharp. Until then, you can do whatever you want as long as you don't cum. Well then."

That pattern.

She closed the door.

I was left on the bed, and I wasn't allowed to calm down this extremely excited boy.

"I have to wear pants that don't stand out, huh..."

What will she do with the semen I have stored until 6 p.m. tomorrow?

What had I done before that?

It's a summer morning when only anxiety hangs in my mind.

I went out to spend the day not being allowed to ejaculate.
