Chapter 27

The reasons for this situation are manifold. The temptation of the pretty Serena, Hena's national treasure-like huge breasts, Yuuna's thighs and smile, the student council president's curvy hips and buttocks, among others…

The decisive blow was the perverted sex with Seredwen.

Once I felt inclined to accept the morning service of my little sister's mouth, which had burrowed into my bed, my thighs naturally relaxed.

"Chururururup♡"

Serena, essentially having received my permission, deliciously sucked on my cock.

Filled with the thought of pleasing her brother's cock, Serena puckered her lips and sucked in.

Then, realizing I was watching, she made a sly face while continuing to consume my cock,

"Slurp slurp slurp slurp."

Her tongue movements were desperate, like she was eager to lick my cock.

Serena, tapping the back of the glans with the body of her tongue, checked my reaction while I, as the brother who had consented to the morning erection care, gently stroked her black hair.

['Onahole Touch']

"Hup…♡"

The 'Onahole Touch' is a skill with the ideal effect of providing happiness upon contact with my body…

In reality, it's no different from a drug. Treating Serena as an onahole is an added sense of betrayal.

It's a sinister skill originally intended to treat women as onaholes and exert control over them.

"Suck… suck… sssuck… suck♡"

Serena cheerfully sucked my cock while gently shaking her hips.

The expression on her face melting under my touch was also adorable.

"Churup… smooch… smack… slurp slurp…"

"Do you like it?"

"Suck… sssuck…♡"

Serena squinted her pretty purple eyes.

When our eyes met, she focused solely on teasing the glans trapped in her mouth with her tongue, as if embarrassed.

The more I stroked and praised Serena's head, the more meticulous her service became.

"*Suck… suck…* Delicious… My handsome and cool big brother's hard cock…♡ Better than food♡"

Ah!

Serena even sucks on my balls.

Using her pretty face entirely, Serena nuzzles and rubs against my cock with affection.

'I'm so turned on…'

"Hah…"

Perhaps it's because of her enthusiasm for her first fellatio. She seems tired around her jaw.

When I gently stroke her head, Serena gives my cock little kisses, cutely grumbling.

"Big brother's cock is so big, it's hard."

"You can take it easy."

"Smooch… smooch…"

Serena continues to kiss my cock.

"I was the first to kiss big brother's cock."

"Where did you learn to say things like that?"

"Slurp slurp slurp♡"

Serena, pretending to be innocent, licks the firm glans from side to side in succession.

"Put it in your sister's mouth, brother…♡"

"Open your mouth."

"Ah~ah."

I place the glans on Serena's offered tongue and push my cock all the way down to her throat.

"Chomp♡♡"

Serena purses her lips and accepts my cock.

The tongue underneath the glans moves frantically, almost as if welcoming it, driving me crazy.

'If I had known my sister's mouth could feel this good…'

I would have entrusted it to her sooner.

With such shameless thoughts, I sinfully press down on Serena's head.

The act of making her suck her brother's cock and holding her head in place ignites my brain incredibly in the morning.

"*Huff*… umm…?"

Serena, in a position where she can't run away if I come.

With an innocent face, she smiles with her eyes as if saying, 'Big brother, please come.'

I lift my hips and thrust my cock back and forth, barely touching Serena's throat.

"Guk, ugh, oogook."

This seems a bit difficult.

I adjust the intensity for Serena, who is having a hard time as a first timer.

When I touched her with 'Onahole Touch', Serena's eyes opened.

"Heehee…. aah…."

Is it okay to make my younger sister this horny in the morning?

Even though Serena's eyes are dangerously open, I do not stop the 'Onahole Touch'.

It's because the more I treat her like an onahole, the better she looks.

In the moist and swollen mouth of Serena, her sensitive tongue is exposed as it seems to come out of her tightly closed lips.

"Serena…!"

I restrained Serena's head and ejaculated heavily without warning.

Splurt! Splurt!

"Hoo-bup!?"

Serena was surprised by the sudden mouth ejaculation and closed her lips, but her cheeks swelled because of the large amount of semen.

It felt strangely satisfying to destroy Serena's face with the mouth ejaculation, even though it might sound ridiculous.

Splurt! Splurt! Splurt! Plop!

I stir inside Serena's mouth.

"Don't spill it, Serena."

"Hoo-bup! *Slurp*… Hoo… hoo-bup… *gulp… gulp…* Oh… ugh…."

She's doing well without vomiting….

While stroking and petting Serena, I continue to ejaculate.

Splurt! Splurt! Plop! Plop!

"Gulp… gulp…"

Serena was working hard in her mouth, but it couldn't be helped that the semen leaked out for the first time.

She looks so cute.

Oh…. This is so thrilling….

The pleasure I experienced yesterday while masturbating was nothing compared to Serena's incredible mouth. The way she heats up my cock with her diligent tongue is more than just a simple release. Serena looks so adorable.

"Hap… ehe…"

It seems my satisfaction was conveyed through my twitching erection, as Serena gave a bashful smile.

"Should we start getting ready to go to the academy?"

We can't keep going and be late.

"Big brother, we still have some time…"

But this time, Serena clings to me like she's begging for an allowance.

"Serena?"

"….."

Kneeling on the bed, Serena slightly lifts her skirt, revealing her sexy, wet gray panties quite explicitly.

"Can't you… pamper me more?"

Serena slides down one side of her panties. I instantly understood what she meant.

'Sex with my younger sister.'

Though she is my younger sister in 'Onaaka'…

This is not a matter to be taken lightly.

"I have condoms…"

"Serena, that's…"

Rejecting her would surely hurt her feelings. Having let her indulge in pleasuring me, could I, as her brother, ignore Serena's yearning desire without disqualifying myself?

"Mmm, big brother…"

Serena whines cutely with her panties pulled down on one side.

"Big brother, you're the one who made me like this… Right now… I'm so… distressed."

I've overindulged in the 'Onahole Touch'…

How do I fix this? I can't just have irresponsible sex with my younger sister like this.

"Come here, Serena."

"Kyah! Big brother…!"

I need to wrack my brain for a solution. Think of something, Kim Sang-hyuk…!!

I sat at the edge of the bed with my legs outstretched and had Serena lie across my lap.

It's the 'spanking' position.

"Big brother…?"

Smack!!

I slapped Serena's plump bottom with my palm.

"Huah!! Big brother, what are you doing?"

While Serena flails her legs in confusion, I firmly hold down her pelvis and smack her bottom again.

It's quite a sight.

"Hah!"

Serena clenches her buttocks tightly.

"You have other things to be scolded for by big brother. Aren't you going to come to your senses, Serena? You're not a child to be punished like this… It's embarrassing!"

Smack!!

I slapped Serena's bottom once more.

"Huah! Big brother… But still…"

"You want to move on to sex even though you couldn't swallow all of big brother's semen?"

"…Ah."

Serena puffs up one cheek. This time, she seems to be pouting.

"It's because big brother's amount is abnormal. It's totally different from what I learned in the books."

"Are you blaming your big brother now?"

Smack!

"Kyaaah!"

Serena's face turned bright red as she covered it with her hands. The shame of being all grown up and sprawled across her brother's lap for a spanking.

"Did you do something wrong?"

"Hah… Yes, I did something wrong…"

"What did you do wrong?"

"Not taking proper care… of my big brother's cock with my mouth…"

Serena gently wiggles her bottom.

"I asked you to take care of my pussy… I'm sorry…♡"

Is this right? Trying to avoid a sex event, it feels like I've stumbled into an even more perverted and dark event. Hmm. This must be right. Probably.

While spanking Serena's bottom, I also stimulate her pussy.

"Ah, ah…! Mmm…"

I'm taking responsibility for Serena's pleading pussy.

Using punishment as a pretext…

I soothe her by kneading her swollen red bottom.

"I don't deal with children, you know?"

"Hah… Yes… Next time… I'll swallow it all… I'll become a lady who can properly handle my big brother's needs…"

Spank! Spank! Spank!

I discipline her with smacks on her bottom.

"Mmm… Ahh… I did… I did something wrong…♡"

As I spread Serena's defenseless bottom,

I insert my finger into her pussy.

"Hah… Hah…"

"Spread your legs."

Serena flinches but obeys my command, spreading her legs.

I tease her dripping wet pussy with my finger, slipping it in and out.

Lying face down, Serena twitches with each movement.

"I'll help you a little, though."

"Ah… Ah… It's… Big brother's… fingers…"

I lift her skirt and pull down her panties.

Slipping my hand beneath Serena's pale bottom, I stir her tight pussy with my fingers.

Squelch, squelch, squelch, squelch.

I gently stroke Serena's hair as I delve into her.

"Hah… Hwat… Thank you, big brother…"

"What are you thanking me for?"

"Thank you for taking care of your immature little sister's pussy… Hng, hngahh…"

"Because I'm your big brother."

While Serena writhes on top of my legs, in heat, I gently stroke her hair and tease her narrow pussy with my fingers.

Squelch, squelch, squelch, squelch.

"Hng, hng, hngh…"

Serena's pussy juice flows uncontrollably.

It would have been amazing if we had sex.

Thinking this, I hook my thick fingers inside and continue to shake.

"Ah. No… Ahh… Oppa… Big brotherrr…!"

"Does your pussy spew juices because your big brother's fingers are inside?"

"I'm embarrassed…"

Slip, slip, slip, slip…

I bend my fingers into an 'L' shape and gently rub inside Serena's pussy.

"Ah, ahh… Huhuh…"

Serena wiggles her bottom gently in pleasure.

I press down on my little sister's pelvis from above and persistently rub the spot I've targeted.

Squelch, squelch, squelch, squelch!

"Ah… Ahh… Big brother… Hah… I did wrong, I did wrong… I'm sorry for being naughty… Sorryyy…♡♡"

At this moment, after I watch Serena getting cocky while pleasuring me with her mouth and hands, it feels like I'm properly putting her in her place.

Showing her that I'm the one in charge.

Without stopping, I scoldingly stir Serena's pussy.

Squelch, squelch, squelch, squelch.

"Yes! Ah… Ah… I like it… Your thick fingers… Ah… Ah… It feels good…"

"Do you like reaching the climax in my arms?"

Nodding repeatedly, Serena hides her face with her hands, but she can't hide her breath. No matter how shy she is, Serena's defenseless pussy continues to spew her juices as if she's confessing that she loves being fingered by her brother.

The bed sheets will need washing.

"Ah, ah, ah, forgive me… Next time I'll do it properly, I'll become a proper lady… Forgive my inexperience…"

"Ah♡ Ah, ah, big brother♡"

Serena moans cutely as she is brought to a strong climax by the vigorous movement of the fingers. Even after the fingers are removed, Serena's body twitches as if still savoring the sensation.

'Whoa.'

The timing was perfect.

"Let's go to school, Serena."

Smack.

"Ah!"

I wake Serena up by lightly slapping her buttocks with my palm.

It's the third day of being transmigrated to 'Onaaka'. This morning, too, I started with a work of art.

Translator Note: I'm switching my wording for 'vagina' to 'pussy' because in some sentences it feels awkward to use the word 'vagina'. But I might just use both wording depending on the sentences in the future. I hope you guys (my readers) don't mind…
