Chapter 685 – #138_The Master’S Challenge (4)

#685

1.
A declaration of spirit and a fall to depravity.
It was a truly mismatched combination, like an Americano and miso soup.

However, Siwoo was intimidated by Rinne’s declaration, which even carried a hint of overwhelming force.

Was this how the Demon King felt, watching the hero rise higher with each obstacle and hindrance?
A sense of urgency followed, that he would be dragged around by the situation as it was.

He realized just how significant the absence of pleasure was.
If only Rinne had felt normal pleasure, he could have made her look pathetic and defeated her.

But Rinne had none of that.

If she could endure the physiological revulsion, discomfort, and a little bit of shame, she could easily withstand all of Siwoo’s hardships. She was truly an invincible boss.

-Slurp! Slurp! Slurp!

It didn’t change even as Siwoo’s tongue wriggled and dug into Rinne’s backdoor.

“Kuh, Master’s backdoor tastes amazing.”
“Is that so?”

Even when he threw out lewd words and sexual harassment, nothing changed.
There was only a slight twitching that wrapped around his tongue, felt intermittently.

“The way you twitch as if you feel good is very sexy.”
“I’m twitching, but I don’t feel good.”

Just like when he had a standing anal sex with Rinne before, Rinne’s mind remained clear as a mirror.

“Th-then, I’ll insert it.”
“Do as you please.”

Attacks like this were meaningless.
No matter how many times he repeated this futile act, Rinne’s reaction would not change.

Having made that judgment, Siwoo knelt behind Rinne and pressed close.
The tatami floor made his knees hurt like hell.

-Squeak…!

Now accustomed to it, it went in much easier, perhaps because he had loosened Rinne’s backdoor with his tongue.
His dick, which hadn’t lost any of its erection despite having already ejaculated once, was easily inserted.

Although Rinne didn’t feel pleasure, it was a hole that had been used many times.

Unlike the early days when it felt like forcing his foot into an ill-fitting shoe, it was now well-broken in.
Rinne also barely complained of pain.

That being said, the sticky elasticity was still there.

“It was tight at first, but now it goes in so easily. I can almost say it’s exclusively mine.”
“That’s not wrong. There hasn’t been any other pervert who has inserted into me.”
“Is that so? Then, how do you feel about allowing such perverted acts to your disciple?”
“It’s nauseating.”

He couldn’t see properly since she was facing forward, but her tone was as calm as reading from a textbook.
He decided to add a bit more intensity to the humiliation.

“The world would be shocked if they knew that the Sword Witch of the world was a pervert who gave her backdoor to her disciple at night.”

This time, there was a reaction.
Rinne’s backdoor tightened as if trying to cut off his dick.

Normally, one would think, ‘Ah, she’s embarrassed’ or ‘She’s getting excited by lewd thoughts,’ but Rinne was different.
Didn’t he see it earlier?

According to Rinne’s anger measurement device, this meant she was angry.
Her subtle trembling was transmitted through their point of contact.

“If you utter that, I won’t forgive you, even if it’s you. And this isn’t my preference, it’s an experiment for amplifying magic power.”
“Is that so? Oh dear… I think I’d be more excited by a perverted Master.”
“…….”

He had to keep shaking her.
Before Rinne became a blank slate and saw through all the obstacles.
He couldn’t afford to worry about the anger gauge or anything else.

“Actually, you like it, don’t you? That’s why you make excuses about amplification experiments because you want to do it with me every day, right?”
“…….”

-Squeeze, squeeze, squeeze, squeeze.

Rinne’s backdoor began to react to the point where he wondered if it was okay.

“The excuse… is… right…”
“Huh? Really? Would you say it yourself?”
“…Stop it.”

Yes, it was better for her to get angry.
Let her explode from not being able to hold back her anger and break the game.

However, Rinne showed another instance of patience.

“I’m ashamed to say… I make excuses every night because I want to enjoy pleasure from behind with my disciple.”
“…….”

What came out after being forced was a lewd declaration that made his dick explode.
Even though he knew it was all a lie, he was still tricked by the allure.

-Twitch!

His dick swelled.
The sensation itself didn’t disappear, so Rinne felt it too.

Either way, his lust was being satisfied by Rinne.
In the midst of this, Rinne had a question that made her tilt her head.

“I have one question.”
“Yes, ask away.”
“Why don’t you have relations from the front?”

That was it.
From what he had observed, his disciple Shin Siwoo was a pervert among perverts who couldn’t resist any hole between a woman’s legs.

The hole for normal intercourse, the hole that normally aroused a man’s sexual interest, should be in the front.
It was suspicious that he never touched the front, simply because he liked the backdoor.

“Ah, that’s because…”

He answered calmly for now, but Rinne’s question had hit the nail on the head.

Yes, this was the dangerous part.

Rinne wasn’t stupid.
He had anticipated that she would notice the unnaturalness as long as this relationship continued.

Just before Rinne felt puzzled by the sudden silence, Siwoo blurted out.

“Because it’s more arousing.”
“I don’t understand.”
“Of course, there’s also the sense of conquest that comes with taking both holes. But leaving the hymen untouched and only penetrating the backdoor. That also has an exciting aspect to it.”
“……?”

Rinne, who couldn’t understand and asked for additional explanation, received an even more incomprehensible answer.

“Just by touching Master’s body as I please, I feel a mental excitement. It’s a forbidden, a relationship of betrayal.”
“…….”

Up to this point, it was somewhat understandable.
He didn’t understand what the feeling of betrayal was, or why it was converted into pleasure.

“Master, you know how perverted it is to do it from behind, right?”
“I know.”
“That’s it. Master, you haven’t received the treatment that a normal woman should receive, and you’ve only come to know men through the hole that perverts enjoy. If you don’t understand the betrayal that comes from this, there’s nothing I can do.”

She still didn’t understand.
In Rinne’s view, the sense of betrayal he was talking about was like the corpse of a grotesque creature that had been crushed without form.

But this much was clear.

That his sticky desire had been directed at Rinne from the beginning.
That he had been looking at Rinne with a sticky and perverted gaze.

“Master is just my cum receptacle for my backdoor.”

She had never thought of it that way before.
She had simply allowed him to insert into one hole in her body.

But now, based on his vulgar expression, she realized.
She was being treated like an object, and at the same time, she was being violated.

“…….”

Suddenly, Rinne felt a sharp pain in her chest and frowned.

It was ridiculous.
She had never done anything worthy of a master for him.
She had never asked for the respect that a disciple should give.

Shin Siwoo was also nothing more than a stepping stone for strength.
Yet, just because of a few times their bare skin had touched, she felt a sense of betrayal she couldn’t understand at his words.

“I still considered you my disciple.”

As if she was too immersed in this master-disciple game.
A sense of betrayal that made her say things she didn’t mean.

Siwoo’s movements stopped abruptly.

The phrase “cum receptacle for my backdoor” was a bit too harsh.
Still, he didn’t expect such a deflated reaction.

It was as if she was hurt by her disciple’s true feelings?
The fact that those weak words came from Rinne of all people was the biggest shock.

“M-Master?”
“…….”

Siwoo had two options.

To ignore Rinne’s subtle reaction and continue the humiliation, causing Rinne to give up on her own.
Or to clarify that it wasn’t true and comfort Rinne, who might have been hurt.

Rinne’s tone and voice were normal.
In fact, he wasn’t even sure if Siwoo’s words had hurt her.

Still, he had some affection for her after all this time, and he felt a bit uneasy about continuing the humiliation without a care.

“Haa… Master.”
“…….”
“You know all this is just a concept, right? There’s no way someone would really think like this.”
“Is that so?”
“Yes, yes, it’s just that the back is better, and the rest is just a plausible setting.”
“You’re an odd one.”

Rinne replied in a tone that didn’t reveal any change in her feelings.

Did she feel better?
Or was she even feeling bad in the first place?

Amidst the growing confusion, the awkward atmosphere was resolved without a word.
Siwoo’s dick, which had been fully erect, also lost some of its strength.

This was troublesome.

It was like coming to a DVD room with a potential girlfriend, and then watching an emotional movie like a laptop, making it awkward to make a move.
It was better this way.

“This has cooled down a bit. It was getting good.”
“…….”
“Shall we stop?”

Just as Siwoo was trying to gloss over the night with an awkward smile, Rinne firmly refused.

“Don’t pull out.”
“Yes, I’ll do as you say… but with this atmosphere, I don’t think the magic power amplification will happen.”
“Keep going.”
“Yes, well. I understand.”

Even if the atmosphere had become a bit strange, Rinne’s body didn’t suddenly change.
As he moved his hips, feeling the sticky sensation and the harmony of the oil, he suddenly heard a strange voice.

“Aah. Aah. Ah. Aah.”

It was a moan coming from Rinne.

Oh my god.

“Haa. Haa.”

At the same time, it was the most rigid moan in the world, like playing back the reading function of an electronic dictionary.
