Chapter 640 – Cohabitation with the Master (3)

How did it come to this?

Early in the morning, Cheondo could discern the restlessness in the eyes of Lee Si-heon.

Again, today, she found herself tasked with aiding his carnal release.

“Master.”

The sound of fabric rustling, as he unfastened his pants, caused Cheondo to inwardly sigh.

‘Again…’

A faint fatigue weighed heavily on her shoulders.

As she set aside her quilt and rose, she was confronted by the sight of her pupil, his bulging undergarments making his arousal evident.

“Wa-wait.”

‘No… Why would a master and student engage in such an act?’

This was a circumstance far beyond what Cheondo could understand.

‘I have been teaching him various martial arts since he was much shorter.’

Their relationship was akin to that of parent and child. At least, that’s how Cheondo had always seen it.

Occasionally, his excessive libido had caused issues, but Lee Si-heon’s sexual urges were typically indiscriminate, a one-dimensional desire not directed at anyone in particular. He understood this well, so it never demanded her particular attention.

But now, things were different.

The emotions Cheondo was now aware of were unmistakably lust and love directed towards her.

Cheondo gazed at Lee Si-heon’s fully erect member. The beastly size of it twitched in anticipation of her touch.

“…”

Silently, she watched it.

His member grew larger still.

“Why does it continue to grow…?”

Her question was futile.

-Thunk.

Carefully, Cheondo extended her hand. The sensation of his arousal against her bare skin… No matter how much it belonged to her student, she could not find it appealing.

It was grotesquely thick, veins visible beneath the skin, the blood circulated so rapidly that she could nearly feel his heartbeat.

She had never seen anything of this magnitude.

Even Cheondo, lacking as she was in sexual knowledge, instantly understood that this was not normal.

-Thunk, thunk.

Today marked the third day.

This was the eighth time she had done this by hand.

Cheondo tried her best to stay detached, but in order to provide the greatest pleasure, she wrapped her thumb around the tip of his shaft and began to move in a twisting motion.

-Squeeze, squeeze.

“Ah, Ah!! Master….”

At the sound of her student’s pleasure-filled voice, Cheondo’s ear twitched.

“Si-Silence!”

-Twist, twist, twist, twist.

Being surrounded by the voice of a man brimming with sexual allure, Cheondo found it impossible to remain unaffected.

“Hugh!”

‘Damn monkey.’

She couldn’t find any kind words as she watched him moan and thrust his hips.

-Thunk, thunk.

As the sensation of her hand, warmed by the friction, intensified, Cheondo subtly distanced herself from Lee Si-heon as much as possible.

Unbeknownst to me, I wished not to expose my pupil to the obscenely ripe, sweet scent of my body, which could flow freely.
No, it was also the instinctive choice of the female, trying to distance herself from the scent of a superior male.

I didn’t wish to acknowledge it.
From a mentor’s perspective, I had to.

How could a mentor feel sexual desire towards a pupil? No matter the circumstance, restraint was imperative.

I restrained.
I merely touched, without allowing myself to feel.
I mustn’t perspire.
I had to maintain my composure, appear as unaffected as possible.

‘…I’m merely assisting in relief. That’s all it should be.’

The moment I recognized this as a sexual act with my pupil, an indescribable feeling would undoubtedly flood over me.

This is not a sexual act.
Merely assistance.

Therefore… I must bring this to a swift conclusion before I acknowledge any wrongdoing.

– Thud, Thud, Thud, Thud!

The pace of my hand intensifies.
The rhythm of my strokes grows increasingly proficient.

I encase the top with my four fingers, and cup the base with my thumb. Using the slippery fluid as a lotion, I shake it rapidly.

[Master.]

In shame, Cheondo closes her eyes as the innocent face of her former student, Lee Si-heon, appears in her mind.

My beloved student.
Such love must not transpire in this manner.

A different kind of love.
No matter what…

– Throb.

No.

“Lee, Lee Si-heon!!”
“Yes.”
“Uh… Isn’t it time to slow down?”
“Just a little more.”

‘…To have ended up in such a relationship… It was not my intention.’

The scent of a male lingers at the tip of my nose. The coarse smell of arousal thickly spreads and fills the room, permeating Cheondo’s stockings.

Cheondo prays inwardly.
Hurry, let it end swiftly.

‘Isn’t it time for you to take over?’

During all the instances of masturbation that had been performed by her hand so far, Cheondo had never once brought her student to climax.

Regardless of how vigorously she shook, perhaps the sensation was not enough. At the end, it was always Lee Si-heon who finished himself off.

For Cheondo, the end of the act was naturally marked by the movement of Lee Si-heon’s hand.

– ThudThudThudThud!!!

Lee Si-heon must move his hand to escape.
Unconsciously, Cheondo grips tightly, shaking his cock as if it were ablaze.

‘Please…’

Start moving yourself. Isn’t it time?

– Thud! Thud! Thud! Thud! Thud! Thud!

The student’s erotic breathing grows heavier. Finally, the words she had been waiting for are spoken.

“Master, uh… Wait… I’m coming…!”

Finally… No.
Wait a second-

“What do you mean you’re coming… What!?”

The pupil’s cock swells, and thick semen sprays not into the tissue, but onto her chest and shoulders.

– Splurt! Swoosh!!

“Uh, uhhh!!! What the hell is this–“

A monumental amount, enough to drench the bed.

Startled, Heaven closed her mouth, feeling the residue of semen on her cheek.

“…Ah.”

A delayed epiphany shook Heaven’s mind.

‘Could it be?’

She had provoked her pupil’s lust to its peak.
In her self-hypnosis, intended to aid his release, she had led him to climax. This realization rendered all prior justifications void.

Heaven swallowed, severing the lingering taste of his release in her mouth several times.
What was once assistance had become a clear-cut sexual act.

The pungent, masculine scent that had filled her nostrils invaded her mind.

“Hah, hah….”

Her student, having released his seed, breathed out the accumulated tension. It was crude, even lascivious… Lascivious? Where did such a peculiar sentiment spring from?

Unconsciously, Heaven placed a hand upon her breast.

-Thump, thump.

What was this emotion… A sense of accomplishment?

She remembered her student’s past actions, clumsily pleasuring himself after she had rejected his advances.

But today was different. Was it due to an unnoticed improvement in her skills?
She felt a small sense of satisfaction at his diligent response.

Yet, she was also angry at herself for crossing the line.
Where had this emotion originated from?

…A female’s feelings during a sexual act?

“Teacher.”

-Flash!

“Ah, ah?”

Heaven, who had been lost in thought, uttered a lifeless sound.

A complex and subtle emotion she could not fully comprehend.
A feeling of unease yet oddly thrilling, with a touch of shame mixed with a slight sense of elation.

Several entwined feelings made her eyes squint.

“Teacher?”
“What is it, Nya!”
“Nya?”

-Thump, thump, thump.

Her heart ached.

She needed to stop this behavior now. A belated realization hurriedly flickered across Heaven’s mind.
If they were to go further from here, she feared she might never be able to return.

* * * * * * * * * * *

“……”

Her words had noticeably decreased.

“Teacher, do I have to dry my hair?”
“…Don’t speak.”

A face that had clearly received a shock.
As she cautiously closed the distance, Heaven subtly widened the gap between them.

It seemed the events of the day had greatly stirred her.

“How many of those clothes do you possess?”

Despite having put her used garments in the washing machine, Heaven had donned new full-body stockings, the origin of which was unknown.

Heaven’s face, freshly showered, was flushed, perhaps due to the hot water.

“It’s none of your concern. Wretched thing.”

Her words were twice as harsh as usual.

‘Indeed.’

The reasons Cheondo had participated in my self-gratification were multifaceted, stemming from a history of rejecting my emotions and our mutual desire to be together.

Until the moment of my climax, I had been stable, but the aftermath left me feeling disquieted.

“Siheon…”

In a grave tone, Cheondo addressed me.

“From now on, let’s stop this. No matter how optimistically we see it, this is wrong. We are… master and student, and such sexual acts should not occur.”

I listened intently to her words. The delicate balance of our relationship seemed to recoil sharply at the first sign of crossing established boundaries.

I took in Cheondo’s state. Her full-body stockings, drenched from the shower, clung to her, soaked with a fine dew. The moisture that had evaporated with her sweat filled the air with steam and carried her scent. As my gaze lowered, I caught sight of the tantalizing peaks of her breasts standing erect.

I was aroused.

Because of my teacher.

Her lack of sexual experience had left her unable to process this strange excitement.

-A burst.

The scent of an aroused peach filled the air. I took a deep breath, suppressing my lust as much as I could.

“Siheon…?”

After a long silence, she cautiously looked up at me. Her moist eyes were incredibly endearing.

“…Are you disappointed? Have you come to hate your teacher?”
“Teacher.”
“Regardless… I believe this isn’t right. My hand stroking your member, this is something that should not be happening.”
“Teacher…”

I only uttered her title, yet Cheondo, unable to contain her restlessness, began to fidget, her feet shuffling.

Her nipples stood out prominently.

Perhaps it was an attempt to escape the subtle pleasure and hormonal intoxication.

Cheondo shut her eyes as if to make a resolution.

“I’m sorry… I think the time has come for me to reject your feelings.”
“Is it because of someone you like?”

Cheondo didn’t respond.

Perhaps that was part of the reason.

I paused for a moment, exhaling a brief sigh. Cheondo’s body shivered.

“…That person.”

The one she liked.

“It’s me.”

Cheondo kept her head down, her face unreadable.

“The person you liked was me. And to you, I was a death sentence. But you see, your sister is still alive. Her name is Hong Yeon. You know that, right?”

There was no response.

Even though I revealed my identity passionately, Cheondo failed to acknowledge it.

“Yes, it wouldn’t reach you.”

I said it knowing the futility.

It’s meaningless after all.

I couldn’t kill the World Tree of Justice right here and now, so what was the point?

“Teacher.”
“…Hmm?”

When I spoke without any intentions, she finally reacted. At Cheondo’s dejected words, I took another deep breath, then gradually moved closer to her, shifting my body to the side.

Cheondo no longer maintained the distance as she used to.

“Truly, is it impossible?”

A plea filled with desperation.

Cheondo’s pupils quivered intensely, and after a moment, she lowered her head. Before long, a voice resonated, seeming as if it originated from a mouse hole.

“…It’s strange.”

“Hm?”

“It’s strange, I say. Why do I… think of him whenever I see you?”

Presumably, ‘him’ referred to Do-won’s image of me.

No matter how intensely I am perceived as a different person, the ultimate conclusion is me. It’s not affection towards another person, but a deep connection felt for me – the identical entity.

‘…If only.’

I yearn for my disciple to love me more intensely.

Already aroused by my presence, the moment is now.

“Master.”

“…What is it?”

“I apologize.”

My hand encircled Cheondo’s neck, and I fervently kissed her.

“Huh?!”

Cheondo’s eyes widened in surprise. A wafting scent of peach. I unleashed the pent-up desire I held back all this while. I fervently groped Cheondo’s breasts, which had remained untouched until now.

-Squelch.

Just as soft as I had imagined.
And the tangy sensation.

“Ah! Uh!? Oh… What, what are you doing, Lee Si-heon!!”

Cheondo, enraged, issued a vehement warning. But her voice was tinged with a hint of fear.

I pushed her off my shoulder, and using my strength and weight, I pinned down Cheondo, who had grasped my wrist, beneath me.

“Huh…!”

Cheondo, unable to even utter my name, attached and detached her lips with a peculiar expression.

-Thump Thump.

The sound of Master’s heartbeat.

“I yearn to make you mine.”

“What…?”

Not as a disciple serving the same master.
But as it stands now.

I desire to make her mine, to forge a deeper connection.

As I twisted the hardened part of her chest, which was more prominent than before, Cheondo’s body shuddered.

“Ah! Stop, stop!!”

I seize what I desire.

Even though it’s a somewhat aggressive approach,
It’s because I genuinely yearn for it.

-Squelch.

“Master… Master!”

“Please stop…Ahh!?”

I firmly squeezed her buttocks. Waves crashing between my fingers.
A ripple formed on her skin.

Cheondo’s suppressed moan finally erupted.

“Huuk♡”

Burying my face in her sour breastbone, I lost myself in the sensation.
