## Chapter 683 – #138_The Master’S Challenge (2)
#683
1.
A man’s sexual arousal isn’t solely determined by physical pleasure.
Who the partner is and the situation are also crucial factors.
Considering that tendency, Siwoo was experiencing an excessive amount of mental arousal.
Siwoo knew Linne’s usual appearance.
Her beauty, like that of a noble lady of the castle, combined with the refined aura of a warrior.
If one were to compare her to a flower, she would be like a black rose.
So beautiful, yet if you tried to pluck her, you would die from the poison on her thorns.
Moreover, what about her strength?
During sparring, Siwoo was always the one who ended up broken and sprawled on the floor, while Linne looked down with a haughty gaze.
And now, she was kneeling naked in front of Siwoo, wearing only pantyhose.
Linne looked up, perhaps to gauge Siwoo’s reaction in that position.
The reversed eye level and the direction of her gaze were, in any case, enhancing the feeling of conquest.
-Lick, lick-
Linne’s tongue meticulously licked his rod, cutting off his thoughts.
No matter how cold and prickly she was, her tongue was naturally warm and smooth.
The strands of hair that occasionally brushed against his thigh and her lukewarm breath felt chillingly good.
Moreover, he could now observe her cherry-like nipples and her perky breasts, which he rarely had the chance to see.
It could be said that this was one of the best treatments a master could give to a disciple.
“Hrrp… hrrp…”
However, there was something different from what he had expected.
What Linne was doing was not, strictly speaking, fellatio.
From beginning to end, she was only repeating the licking motion.
After licking his rod for quite a while, a drop of pre-cum fell onto Linne’s forehead.
The result of mental arousal combined with ambiguous stimulation that didn’t quite reach it, was that clear fluid began to seep out like a spring.
Linne rubbed her forehead and then made eye contact with Siwoo’s urethra, which was wet as if he had peed.
Even in this situation, there was no trace of sexiness or shyness, only a cold expression.
All that was present was her zeal.
“Is this a precursor?”
“What do you mean?”
“This didn’t usually come out.”
Linne paused her licking for a moment and stared intently at it.
“Is it coming out because it’s satisfying your sexual preference?”
He could tell what she was misunderstanding.
She seemed to think of it as some kind of essence, like the liquid that collects when grilling matsutake mushrooms.
Although they had done it quite a few times before, this was the first time Linne was actually meeting his rod, as she had always inserted it right away.
“That’s not it.”
“Why?”
“There’s no point in asking me why… This is pre-cum. It always comes out. You just haven’t had a chance to see it properly.”
“……”
Linne’s eyes widened and then narrowed slightly.
This was a case of knowing something in theory but not being able to apply it in practice.
Still, she didn’t throw a tantrum or get annoyed.
She started licking his rod again, just like before.
Siwoo had thought that his psychological resistance would be at its limit before Linne realized what pre-cum was.
But now, he had a hunch.
Wasn’t it possible that Linne didn’t even know what fellatio really was?
“…Churp…”
And that was the correct answer.
Last night, Linne had only eavesdropped on their activities from behind the door.
The only thing she had visually observed was the sight of him thrusting into Dorothy’s rear end and the handprints on her buttocks, after belatedly returning to sense the magical energy.
The rest was all based on her assumptions from the sounds and conversations.
If what Dorothy and Siwoo had done was a battle, Linne would have been able to picture most of the scene in her mind.
But unfortunately, Linne didn’t have any prior knowledge of how to give and receive caresses based solely on hearing.
Her life had been devoted to the sword, after all.
Therefore, it didn’t even occur to her that she had to put that huge thing in her mouth until her jaw fell off.
She was just wondering, ‘The sound is different from when it was with Dorothy.’
“Chup.”
That’s why Linne started trying various things.
At first, she only stimulated him with the tip of her tongue, but now she was using her entire tongue.
The range of her caresses, which had only been on his rod, had also widened, and her tongue finally touched his smooth balls.
“Ooh.”
This was a pleasure that only someone who had received caresses could understand.
Somewhere between ticklishness, comfort, and pleasure.
The first time he had received a caress on his balls, he was surprised at how good it felt, almost as good as fellatio.
Come to think of it, it was only natural.
The scrotum was a sensitive erogenous zone.
Having it gently licked by a tongue that was incomparably softer and more delicate than a man’s was bound to feel good.
Still, just in case, he gave her a warning in advance.
“Master, you absolutely must not bite or suck.”
“Make it an order.”
“Just lick it with your tongue.”
“Churp, churp, churp.”
Linne, having confirmed that Siwoo’s reaction was more definite, grabbed his rod with her hand.
Then, after clearly exposing his balls, she began to lick, sweeping up from below, as if separating the balls, all the way up to his rod.
The tip of her delicate nose and her forehead occasionally touched the underside of his rod, leaving traces of saliva, which was another medium that strongly enhanced his mental stimulation.
“Churp, churrrp…”
The problem was that the most concentrated erogenous zone for a man was the glans.
With Linne’s current method of caressing, it would take an enormous amount of time to reach ejaculation.
As Linne diligently served him, his rod swelled up as if it would burst.
Siwoo, feeling a slight pull in his lower abdomen, made a suggestion.
“Isn’t this enough?”
“Not yet.”
Around that time, Linne realized that she couldn’t make the same sounds that Dorothy and Siwoo had made with this method.
No matter how much she stuck out her tongue and licked, she couldn’t make that sound.
Was it closer to a sucking sound?
With a doubtful look, she stared at his glans and then, in that moment, she bit down and sucked.
“Ugh!”
His rod, which had only been receiving ticklish caresses as if he was being controlled, was suddenly subjected to intense stimulation.
Still, Siwoo would have been able to endure it under normal circumstances.
Wasn’t he the owner of a spirit body with unrivaled stamina and self-control?
The problem was the elixir.
It was actually more like a premature ejaculation drug than a stamina enhancer, and he couldn’t adapt to the sudden change, reaching ejaculation immediately.
It had all happened in just 15 minutes and 10 seconds.
-Pop!
His rod, twitching roughly, was pulled out of Linne’s mouth.
Even Linne, a master of martial arts, was nothing more than a newbie taking her first steps in sex.
The scene that followed, when she was flustered by the sudden phenomenon, seemed to play out in slow motion.
-Splat! Splat! Splat! Splat!
“Eep?!”
A small exclamation of surprise and her pouting lips.
His semen, like a water gun, splashed roughly over Linne’s noble face as if he had peed.
Although it had shot out like a water gun, it was thick and viscous like jelly, sticking to her face like a pack.
The amount was no joke.
It seemed to be at least two or three times his usual ejaculation volume.
He shouldn’t have overlooked it.
No matter how much the effects had been reduced, the stamina enhancer that Yebin had prepared was a magical elixir, a product of magic.
“……”
Linne’s face, which had been so pure even while licking his rod, had become a mess in just a few seconds.
Her bright red lips, the bridge of her nose, her surprised and stiff cheeks, and even some of her bangs and the top of her head were heavily splattered with semen.
One of her eyes was closed, unable to open properly, and the other, which could still open, had a drop of semen dangling from her long eyelashes like a butterfly’s antennae.
White flowers had bloomed here and there on her thighs and chest, which she had been neatly holding together.
The scene was extremely erotic, but now was not the time to calmly admire the beauty of the contrast between her black hair and the semen.
This was an emergency situation where he had just given Linne a facial without even properly asking for her consent.
“……”
Siwoo, who was frozen in place, was glared at by Linne’s one eye, which was even colder than he was.
It was only natural that she was angry, as he had smeared a sticky, lukewarm, and fishy liquid, a bodily fluid, all over her face.
At least for Linne, it was similar to spitting all over her face.
“What do you think you’re doing?”
In that moment, an inspiration struck him.
He was already riding a tiger’s back.
Since Linne had prepared herself for this kind of act, it was clear that the level and variety of the acts would escalate.
This time, he had to make her truly sick of it.
Therefore, it was right to be brazen, very brazen.
If he was wishy-washy and played along with her, he wasn’t sure if he could survive the week until Dorothy returned with the data.
“I wanted to cum on Master’s face.”
“You insolent…”
Linne, who had been momentarily stunned by her disciple’s absurd behavior, was about to bare her teeth sharply when she realized the situation.
“Since you told me to order you, I thought you had decided to cater to my preferences.”
“……”
“If you saw how my magic power was amplified after having relations with Dorothy yesterday, you would have known what was needed.”
“……”
“You would have realized that my magic power would never be amplified if you did it the way you were doing it. And since you wore stockings, did it with your mouth, and told me to order you… I thought you were going to cater entirely to my preferences. If I was mistaken, I apologize.”
At least to Linne’s ears, Siwoo’s words made sense.
Wasn’t she the one who had started this with a certain degree of consideration?
Instead of getting angry, Linne flicked her fingers and blew away the bodily fluids that were stuck to her hair and face.
“…So, did you like it?”
“Yes.”
“This is your preference… I can’t understand it. But, do as you please.”
Of course, she didn’t intend to accept everything like Dorothy, but she would try to accommodate his preferences as much as possible.
She decided to try it just three more times.
