Chapter 26

On the way back, I checked my smartphone and saw that there was a missed call from Serena.

[Serena]

Brother, when are you coming? Are you going to be late today?

'On my way right now…'

Message sent. I had completely forgotten that my lovely little sister was waiting for me at home. I hurried back.

"I'm home."

As I took off my shoes, I observed Serena standing in the kitchen. She's the most admirable younger sister in our family, with her black hair and dark eyes, greeting me with a bright face.

"Brother!"

'In her school uniform with an apron on… Nice.'

"You must be hungry. Go wash your hands, and let's eat."

"Okay."

The dinner menu was kimchi stew. It could be eaten even if it cooled down, but Serena seemed unwilling to allow that, busily moving about.

"Just wait a bit~."

"Are you even grilling fish? That's a lot of trouble."

"I was waiting because I didn't know when you'd come home."

"I'll make sure to call ahead next time…."

Serena placed the kimchi stew, rolled omelet, and freshly grilled mackerel in front of me, then sat down opposite me.

"It's okay! Men can be late because they're busy with important work~."

"Serena…."

There definitely was a life-threatening situation today.

[Fucked that pussy right!]1

'...'

Flashes of memory come back to me.

What on earth did I do…

Is that my inner self, influenced by an adult game? I felt a little, no, quite embarrassed.

If I'm this embarrassed, I wonder how embarrassed Seredwen must be. Judging by the student council president's attitude, it seems certain that she strongly defended me, but…

"Do you have a girlfriend now?"

"Chk."

I almost spit out my food.

Serena… She has that look in her eyes like she knows I've been with a woman.

'So sharp!'

"It's okay, big brother. Be honest with me. As a woman, I might be able to give you some advice that could help, right?"

"…The food, it's really delicious, Serena."

"...."

Please forgive me for not being able to say anything right now…

"Give me another bowl."

"*Sigh* Okay."

I pretend to be distracted and focus on the subtitles running on the TV.

[The Empress with Crimson Eyes Arrived This Morning]

[Master Seredwen is well… future plans not disclosed]

– It was business as usual. Those who were meant to die died, and those who were meant to live lived.

…I'm watching the news about a woman in a burgundy dress with black hair and red eyes slipping away from the airport.

It's the same lovely black-haired beauty who was shaking her hips over me today.

Fans' interviews continue on the TV.

– Sister, you're so cool!!

– Having a Master Hunter in Korea definitely makes us feel safer in many ways.

[With frequent observations of abnormal gravitational anomalies in Korea, there are analyses suggesting that these could be signs of a major disaster.]

[In such circumstances, the return of 'Master' Seredwen Evelyn is truly a reassuring event…]

'...'

She also looks stunningly beautiful on TV, but…

Was it thanks to today's intense experience that I found the real thing better? I leisurely entertained that thought.

It seems there was once an opportunity to hastily make her my girlfriend…

'It was a good thing to hold off.'

The woman in question is an SS-Rank hunter whose movements are monitored at a national level.

I am a D-Rank academy student who is often ignored even by my peers.

The very fact that we matched eyes and bodies is like a nonsensical novel.

Those vulgar yet blissful times when I would thrust my cock into her as I pleased and listen to her moans…

It's almost as if it was all a dream or fantasy.

Then, at that moment.

An unfamiliar message popped up on my phone.

[Seredwen Evelyn]

(Photo of a prescription for emergency contraception2)

"*Cough! Cough!*"

"Brother, are you choking? Here, water!"

When did she even register my number?

To send such a picture without a word…

Perhaps she sent it to reassure me that I needn't worry about pregnancy…

I can't even tell if the food is going into my nose or my mouth.

"I've eaten enough. Thank you for the food."

"I'll clean up the dishes."

"Let's do it together."

Serena looked up at me intently from in front of the sink.

"Big brother, you have to tell me if you get a girlfriend, okay?"

"Don't worry, I'm not going anywhere."

Squish.

Serena hugged me as if she had been waiting to do so.

Deep down, I was happy that she cared about me so much that she was anxious about where I might go.

But…

"Big brother…"

Squish. Squish.

Serena, in her school uniform apron mode, clings to me closely.

With a mischievous movement that seems to have a purpose, she tries to tease her big brother's manhood.

"Serena, wait a moment."

Rubbing, rubbing, rubbing…

Despite having been so spent today, I embarrassingly become hard without knowing shame.

There was no way Serena wouldn't notice that fact immediately.

"Mmm."

Serena, seemingly oblivious to the embarrassment of skinship with her big brother, notices his erection and smiles with delight.

"Rest well, brother.♡"

"..."

Throughout my entire shower, I was embarrassingly erect.

Living under the same roof with a beloved SS-Rank beauty who likes me is indeed no ordinary matter.

[Seredwen Evelyn]

How many times did you cum?

[Seredwen Evelyn]

I scrape and scrape, but it keeps coming out.

…Seredwen's KakaoTalk message.

I imagined her scraping out my semen and becoming erect again.

[Kim Sang-hyuk]

I'm sorry.

[Seredwen Evelyn]

Don't spread the word about today's event.

[Kim Sang-hyuk]

I won't.

As if I looked like someone who would boast about 'sleeping with an SS-Rank hunter.'

It's a bit hurtful.

[Seredwen Evelyn]

If you keep our secret.

Huh?

[Seredwen Evelyn]

I'll buy you a meal next time.

Does that make us just brothers and sisters who buy each other meals?

No way. It's more than just a fling.

[Kim Sang-hyuk]

Will you keep my abilities a secret?

[Seredwen Evelyn]

That's difficult, just be glad you're not caught by the Criminal Correction Bureau.

So that's how it is…

[Seredwen Evelyn]

But I'll try to find an appropriate way. Don't worry.

[Kim Sang-hyuk]

Just let me continue my life at the academy.

Because I don't want to part with my classmates.

[Seredwen Evelyn]

I'll try.

[Kim Sang-hyuk]

Thank you, sister.

[Seredwen Evelyn]

Sleep well.

I thought the conversation was over, but there was one more message.

[Seredwen Evelyn]

(Photo of Seredwen, fresh out of the shower)

Wrapped in a towel, it's a selfie of her, seemingly smitten with her own pretty face.

[Seredwen Evelyn]

Ah.

[Seredwen Evelyn]

My Mistake. Don't save it.

…Hmm.

Without much thought, I sent back a photo of myself lying down, exposing my upper body.

[Kim Sang-hyuk]

(Photo of alpha male Sang-hyuk, showing off his muscles while lying down)

Even I can see that any woman's womb would tremble over how handsome I look.

[Kim Sang-hyuk]

Goodnight, sister.

[Seredwen Evelyn]

.

'Just a dot…'

Anyway, it's quiet.

Last night Serena came in… that was nice.

Am I feeling disappointed today because there's no little sister to take care of my erection?

'I must be crazy.'

What am I thinking, dealing with an innocent little sister who can't control her curiosity about sex?

It's abnormal for her to come into my room every day.

If I just don't overstep, we could quickly become more family-like.

'My vitality is crazy, too.'

After what happened this afternoon, you'd think I would be worn out.

Instead, it's like sex has awakened me, and I feel even more energized.

'Serena…'

I can't sleep because Serena's buttocks keep coming to mind.

I tossed and turned for a couple of hours and felt like I was going crazy.

I can't sleep.

In terms of an adult game, shouldn't I have grabbed her in the kitchen earlier when she was flirting?

Maybe then Serena would have happily wiggled her hips in response.

Vulgar thoughts lead to another.

'Adult-game Sang-hyuk is on the move.'

Would Serena accept it?

The erection persists and torments me. I want to relieve it with Serena.

Driven by such beast-like desires, I stood in front of Serena's door with my erection standing firm.

"..."

Through the slightly open door, I can see Serena.

'What is she doing?'

Serena was sitting on the bed, mending my school uniform.

At this late hour…

I began to dislike myself for almost invading my little sister's room with an erection, unable to control my sexual desire.

How is this any different from what Sang-hyuk would do?

'I'm sorry, Serena.'

I, your lousy brother, will get my mind straight.

The best thing to do tonight is to masturbate and sleep.

Ding.

[Hena]

(A picture of Hena's overflowing breasts after taking a shower)

…As if providing masturbation material was a duty of friendship, Hena sent a photo with incredible timing.

[Kim Sang-hyuk]

I told you not to take pictures like this.

While I said that, I was already furiously masturbating to Hena's photo.

Hena wouldn't know.

Sorry, but this is what the male creature is like.

It's Hena's fault for making and sending a lewd picture with these breasts.

[Hena]

Face.

[Kim Sang-hyuk]

Face?

[Hena]

I didn't show it.

…Look at this breast size. If this gets spread on the Backboard3, there won't be anyone who doesn't know it's Hena.

[Kim Sang-hyuk]

Just one more picture.

I was already a libertine with no restraint.

[Hena]

(A picture of Hena making a V with her hands, showing an awkward smile)

The second picture was such that the towel seemed about to slip off, nearly revealing the nipple of one of her breasts.

[Hena]

Oops.

Hena realized this fact belatedly.

[Hena]

Embarrassed.

[Kim Sang-hyuk]

I'll be the only one to see.

Thanks to Hena, I was able to have a stormy back-to-back masturbation session and finally fall asleep.

On the third morning, after being transmigrated to 'Onaaka,'

"*Slurp… Suck…*"

The shockingly pleasant cause of my awakening was Serena.

When I lifted the blanket, Serena was curled up like a cat, with my cock fully in her mouth.

"…Huh?"

"Serena… what are you doing…"

"Pah~…"

Serena took my cock out of her mouth.

It was already glistening with saliva as if Serena had been tenderly licking it while I was asleep.

"It's a little sister's duty to take care of her brother's morning erection."

"There's no such duty."

"Sorry about last night? For leaving you all alone…"

Could it be?

Did she see the tissues I used after masturbating?

That was quite embarrassing in its own right.

"Tissues aren't better than a little sister's mouth, right, big brother?"

Serena took my large cock into her mouth again.

"*Gulp*… Mmm… Mmmph… Pah… You can cum as much as you want. I can do for you what your girlfriend can't since I'm your sister."

Where on earth did she learn such a definition of being a sister?

If it had been the first day of being transmigrated to "Onaaka," I would have stopped her from doing something like this.

But now…

['Onaaka' Morning Bonus Quest★]

[Just enjoy your little sister's mouth as if it were her pussy♡]

The mental brakes aren't working like they did on the first day.
