Chapter 33 – Strictly Disciplining My Sister Who Begs for Sex

There are various reasons for this situation. Serena's enticing beauty, Henna's breathtakingly large breasts, Yuuna's alluring thighs and smile, the student council president's curvaceous hips and pelvis, and so on. The decisive factor is the lewd sex with Seridwen. In the morning, as the temptation to accept my sister's eager mouth on my cock grows stronger, my thighs naturally relax.

"Chururururururub♡"

With what is essentially my permission, Serena deliciously engulfs my throbbing manhood. Lips pursed and filled with the desire to please my cock, Serena draws me in. Suddenly, she realizes I am watching her and continues to work on my shaft with a shy expression.

"Slurp, slurp, slurp, slurp."

Her tongue appears restless, yearning to lick every inch of me. Serena gently taps the back of my glans with her tongue, stealing glances at me as she does so. As an older brother who has consented to my sister's morning desires, I tenderly stroke her black hair with my hand.

["Onahole Touch"]

"Mmm…♡"

"Onahole Touch" is a skill possessing an ideal effect, granting euphoria upon contact with the body… Nevertheless, in reality, it barely differs from a drug. The perverse pleasure of treating Serena as an onahole is an added bonus. Its original purpose is a lascivious skill aimed at asserting dominance by regarding women as onaholes.

*Slurp… Slurp… Sucking… Slurp♡*

Serena playfully sucked on my cock while gently swaying her hips. Her lovely expression, with eyes melting under my tender touch, was endearing.

*Schlurp… Nibble… Smack… Slurp, slurp…*

"Tastes good?"

*Chirp… Gulp…♡*

Serena's beautiful purple eyes squinted. When our eyes met, she bashfully focused her attention on teasing the glans confined within her mouth with her tongue. The more I stroked Serena's head and praised her, the more attentive and thorough her service became.

*Chirp… Suck… Delicious… Your handsome and dashing brother's firm cock…♡ I love it more than food♡*

Oh my!

Serena even sucked on my balls. She used her entire pretty face to nuzzle and pamper my cock.

'Such a turn-on…'

"Hah…"

Perhaps it was due to the overwhelming enthusiasm for her first fellatio. Serena's jaw seemed tired. As I tenderly stroked her hair, she cutely grumbled, peppering my cock with little kisses.

"Your cock is so big, it's difficult, brother."

"You can take it slow."

"Kiss… kiss…"

Serena continued to kiss my cock.

"I'm the first one to kiss your cock, brother."

"Where did you learn to say that?"

"Slurp, slurp, slurp♡"

Serena, feigning innocence, licked my firm glans from side to side.

"Please, brother… put it in your little sister's mouth♡"

"Open your mouth."

"Ah~ah."

I placed my glans on Serena's outstretched tongue and pushed my cock all the way down her throat.

"Choke♡♡"

Serena pursed her lips and accepted my cock. The welcoming movement of her tongue just beneath the glans was driving me insane.

'If I had known my little sister's mouth felt this good…'

I would have indulged sooner. Harboring such shameless thoughts, I sinfully pressed down on Serena's head.

The act of having my brother suck on his cock and holding my head in place set my brain ablaze from the morning.

"Ah… umph…?"

Serena, in a position she can't escape if she tries to resist.

With an innocent face, she smiles with her eyes as if saying, 'Brother, please do it.'

I lifted my hips and moved my cock back and forth, barely touching Serena's throat.

"Guh, ugh, ack."

This seems a bit difficult for her.

Since it's her first blowjob, I adjust the intensity for Serena, who is struggling.

Her eyes widen when I use the 'Onahole Touch'.

"Ah… mmm… hm…"

Is it alright to make my little sister this aroused from the morning?

Even as I watch Serena with her eyes dangerously relaxed, the Onahole Touch doesn't stop.

The more I treat Serena like an onahole, the better her oral pussy feels.

In Serena's saliva-filled mouth, her glans almost come out of her tightly closed lips,

Exposed to her meticulous tongue service.

"Serena…!"

Pressing down on Serena's head, I release my thick cum without warning.

Brrrrrrr! Brrrrr!

"Hmmph!?"

Serena, caught off guard by the sudden oral assault, purses her lips in embarrassment. However, her cheeks swell up due to the copious amount of semen released. She felt a strange pleasure in seeing Serena's face ruined by the mouthful, almost to the point of being comical.

Brrrrrrr! Brrrrrrr! Brr! Brr!

The fluid is stirred within Serena's mouth.

"Don't spill it, Serena."

"Hmmph! Swallow… Huh… Hmmm… Hmmph… Gulp… Gulp… Oh… Mmm…"

She manages to hold back her gag reflex and performs well. Stroking and praising Serena, he continues to release his seed into her mouth. Brrrrrr! Brrrrrrr! Brr! Brr!

"Gulp… Gulp…"

Although Serena tries her best to accommodate the load, it's her first time, and some semen inevitably leaks out. Her effort is endearing. God, this is incredible…

The sensation of Serena's mouth on him is incomparable to the unfulfilling release he experienced while masturbating the day before. The tender warmth of her tongue on his cock as she licks and sucks goes beyond mere physical relief. Serena appears so lovable.

"Hah… Eheh…"

Serena grinned widely, as if my satisfaction had been transmitted through my erect cock.

"Shall we get ready to go to the academy now?"

We couldn't be late again if we continued to fool around.

"Brother, there's still some time left…"

But this time, Serena clung to her brother as if begging for pocket money.

"Serena?"

"…"

Serena, kneeling on the bed, slightly lifted her skirt.

Her sexy gray panties were clearly damp.

"If you adore me more… is that not okay?"

Serena slid down one side of her panties.

I instantly understood what that meant.

'Sex with my sister.'

Although she's the younger sister within "OnaAka"…

This isn't a matter to be taken lightly.

"We have a condom…"

"Serena, that's…"

If I refused, she would undoubtedly be hurt.

Wouldn't it be a disgrace as an older brother to ignore Serena's pleading pussy after indulging her desire to suck my cock?

"Ugh, brother…"

Serena, with one side of her panties lowered, gently flirted and acted cute.

"Oppa, you made me like this… Right now… I'm so… distraught…"

I've overused the 'Onahole Touch'…

How can I make amends? I can't have careless sex with my sister like this.

"Come here, Serena."

"Kyaa! Oppa…"

Think hard, Kim Sang-hyuk…!!

I sat on the bed with my legs spread, making Serena lie face down on my lap.

It's a "Gung-di-pang-pang" position.

"Oppa…?"

Slap!!

I smacked Serena's firm buttocks with my palm.

"Whew! Oppa. What are you doing?"

As she flails her legs, I firmly hold down Serena's confused hips, and slap her backside again.

It's quite a sight.

"Haha!"

Serena clenches her buttocks.

"I have other ways to discipline you, Serena. Aren't you going to come to your senses?"

"Oh, I'm not a child anymore, this kind of punishment… I'm embarrassed…!"

Slap!!

I slap Serena's buttocks one more time.

"Whew! Oppa… But…"

"You couldn't even swallow all the semen, and now you want to move on to sex?"

"...."

Serena puffs up one cheek, clearly upset this time.

"Your amount is abnormal. It's entirely different from what I learned in the book."

"Are you blaming me now?"

Slap!

"Ahh!"

Serena's face turns beet red, and she covers it with her hands.

Now, as an adult, she finds herself in the humiliating situation of lying across her brother's legs.

"Did you do something wrong?"

"Uh… I'm sorry… I was wrong…"

"What did you do wrong?"

"I didn't take care of your cock properly with my mouth…"

Serena gently shakes her hips.

"I'm sorry for asking you to treat my pussy so sweetly…♡"

Is this correct? It feels like she tried to avoid a sex scene only to end up in an even more perverse, lewd situation.

Hmm. This might be right. Probably.

He stimulates Serena's pussy by spanking her ass.

"Ah, oh…! Mmm…"

He takes responsibility for Serena's aching pussy.

Using corporal punishment as a pretext…

As Serena's red and swollen buttocks are gently massaged, the pain is soothed.

"I don't involve myself with inexperienced girls, you understand?"

"Hmm… Yes… Next time, I'll take it all in… I'll become a lady capable of satisfying your desires…"

Smack! Smack! Smack!

Her buttocks are disciplined with a series of spankings.

"Yes… Ah… I made… a mistake…♡"

Spreading the defenseless Serena's cheeks apart,

I inserted my fingers into her moist vagina.

"Ah… Ah…"

"Spread your legs."

Startled, yet obedient to my command, Serena opens her legs.

I push my fingers into her slick opening and tease her wet inner folds.

Face down, Serena shudders in response.

"I'll help you out a bit."

"Ah… Ah… Your… fingers…"

Lifting her skirt, and pulling down her panties,

I slide my hand beneath Serena's fair buttocks and stir her tight, quivering entrance with my fingers.

Swirling, swirling, swirling.

I gently stroke Serena's hair and continue my ministrations.

"Ah… Ah… Thank you… Oppa…"

"What are you thanking me for?"

Inexperienced little sister's pussy… ah, yes… thank you for indulging me…"

"Because I'm your brother."

Gently stroking Serena's hair as she writhes atop my legs, her lust overtaking her,

I tease her tight, pulsing pussy with my fingers.

Squish, squish, squish.

"Mm, yes, yes, ah…"

Serena's juices flow uncontrollably from her slick cunt.

Sex would have been incredible.

Thinking this, I slide my thick fingers inside and continue to thrust.

Squish, squish, squish!!

"Ah, no… ahh… brother… brother…!"

"Do you squirt fountains just from my fingers?"

"I'm embarrassed…"

Swish, swish, swish…

I twist my fingers and gently rub the inside of Serena's quivering pussy.

"Ah, ah, ah…"

Serena wiggles her hips with delight.

I firmly press down on my sister's pelvis from above and relentlessly target the spot I've been aiming for.

Squish, squish, squish, squish!

"Oh… ah… brother… I was wrong, I was wrong… I've been teasing… I'm so sorry… ♡♡"

In this moment, watching her brother become excited by her mouth and hands, Serena felt a sense of hierarchy being properly established. It was clear that her brother held the upper hand.

Without stopping, he continued to tease and prod Serena's vagina relentlessly.

"Ah! Ahh… Hee… It's amazing… Your thick fingers… Haa… Haa… I love it…"

"Do you like orgasming in your brother's arms?"

Nodding, nodding, nodding.

Serena repeatedly nodded her head, covering her face with her hands.

But hiding like that wouldn't work. No matter how embarrassed she was, Serena's unprotected vagina kept squirting a continuous stream, as if confessing her pleasure from her brother's skilled touch.

*Squelch, squelch, squelch*♡

The bedsheets would need to be washed.

"Ah, ah, ah, please forgive me… Brother…! Next time I'll do it properly, hic, hic, hic, I'll become a refined lady's vagina… Please forgive my inexperienced one…♡"

*Poke, poke, poke, poke, poke*♡

"Ah♡ Ahh, huu, brother, brother♡"

As Serena panted adorably, her brother intensified his finger movements, teasing her even more vigorously to bring her to an intense orgasm.

Serena, who climaxed relentlessly from early morning until she was gasping for air,

continued to quiver her ample buttocks even after I withdrew my fingers, as if she was still savoring the sensation.

'Phew.'

Perfect timing.

"Let's head to school, Serena."

*Smack.*

"Ah!"

I rouse Serena with a gentle slap on her behind using the palm of my hand.

The third day of being possessed by "OnaAka."

Today, as with every morning, I began my day with a touch of erotic art.
