City of Witches Chapter 12

Human strength may be utterly insignificant in the face of a given fate.

Even Siwoo, who had never doubted that life was something one carved out for oneself, had recently been feeling the capriciousness of fate.

Before being captured and brought here, Siwoo was a promising mathematical talent in his own right.

He graduated early from a science high school that sent most of its students to prestigious domestic universities or top-tier universities abroad.

Having caught the eye of a professor who had noticed his talent since childhood, he entered the Massachusetts Institute of Technology on a recommendation.

Interview requests came in, and newspapers even ran articles calling him a mathematical genius born in Korea.

While not neglecting his university activities, he won awards in several international mathematics competitions, and a paper he individually prepared on essential singularities was published in an academic journal.

Granted a special exception, he earned his master's degree with that paper and, before preparing for his doctorate, proudly fulfilled his national defense duty from ages 21 to 23, completing his service as an Army sergeant.

His burdens were lighter. Soaked in the joy of being able to research to his heart's content, the plane he boarded crashed in the middle of the Pacific Ocean.

When he came to his senses, he found himself kidnapped to the Witch's city of Gehenna.

For the next five years, he performed his duties as a cog in Gehenna's machine until his bones ached.

Feeling that he would die here without accomplishing anything if things continued this way, for the past three years, he had been diligently studying Magic in his spare time to escape Gehenna.

Fortunately, Magic had a significant connection to mathematics and geometry.

For example, the formula for calculating the conservation law of magic power based on location applied line integrals, and controlling the noise generated during magic power operation required Taylor series and Fourier series.

Fortunately, the complex analysis Siwoo had majored in had many aspects that aligned with major Magic formulas, so the Ark for his escape was being completed at a remarkable pace.

If he could just hold on for about one more year, he would have a way to escape this tedious place...

"Uuuuuh..."

To be caught in a sudden death crisis by the mischievous Twins.

Siwoo watched Odil, who was plastered against his upper body, mixing her tongue with his in a sticky kiss, and sang the national anthem in his head.

Human patience is truly amazing.

To be able to not even flinch while kissing such a beautiful woman.

"How is it? Did it get bigger?"

"It's the same as before, Sister."

Odette, who had been staring intently at Siwoo's thing, shook her head as if to say it was hopeless and climbed down from on top of him.

"It doesn't get bigger even when touched, and it stays the same even when kissing as the book says."

"Didn't they say there are days like this? I'm going to put my pants on now, so could you please untie this?"

Good.

If their interest wanes like this and they leave, nothing could be more grateful.

Just then, Odette, who had been reading the guidebook beside them, tapped Odil's shoulder.

"Sister... look at this."

Even Odil, who had been more proactive compared to Odette, froze stiffly the moment she saw the page Odette presented.

The page contained a somewhat explicit scene.

A man standing naked and a woman kneeling below him.

An illustration of the woman opening her mouth to take the male member into her mouth.

"......."

"......."

"......."

An uncomfortable silence.

Odil, Odette, and Siwoo all kept their mouths shut for now.

He barely endured a kiss, but fellatio?

How could he withstand that?

Without a doubt, his thing would grow vigorously, and perhaps that intense reaction could stimulate the Twins' curiosity.

Moreover, that book was a guidebook teaching sex to naive maidens.

There was no guarantee that the immature Twins wouldn't get carried away by the mood and follow through to the end.

"Lady Odette, this is where urine comes out. It's dirty with all sorts of germs."

"Really?"

Talking to Odil was impossible.

He had to target Odette.

"Yes, I think that guidebook seems to have transcribed quite outdated theories. I am deeply concerned that you, Lady Odette, who will become a central figure in Gehenna in the future, might contract a terrible disease because of me."

She listened quite seriously to Siwoo's earnest advice.

Then, Odil came up with a very good idea.

"Odette! How about we try it like this?"

And the novel idea Odil came up with was, for Siwoo, the worst of bad news.

The hole where urine comes out is ultimately the urethra.

In other words, it's not dangerous as long as you don't directly suck the glans part with your mouth.

The exterior can be properly disinfected with magic that eliminates bacteria.

Even if you do get sick, a healing song would be sufficient for recovery.

Based on these four grounds, the decision Odil reached was very simple.

Just lick the shaft part with the tongue.

"That book is really wrong! You'll regret it!"

"Assistant, shut up."

"Assistant, please be quiet."

No matter how much Siwoo struggled and cursed, the Twins, who had already made up their minds, had no intention of listening at all.

Then again, if they were Twins who obediently listened to a slave's words, Amelia wouldn't have had such a headache.

The two girls, holding Siwoo's thighs like cushions in their arms, gazing intently at his cock.

He could feel their piercing gazes and ticklish breaths grazing the area around his balls.

"Odette, we do it simultaneously."

"Okay, Sister."

After exchanging glances, the two girls took a deep breath and slowly stuck out their tongues.

The warm sensation, like a snail crawling over the smooth, shaved balls, prepared for visual observation during the experiment.

"Ugh!"

Siwoo gasped.

At first, it was ticklish.

A sensation like poking a stick into the sexual desire in his gut.

The cock, which he had barely kept subdued, twitched immediately.

"Oh?"

"It moved!"

Odil and Odette simultaneously made the same surprised expression and congratulated themselves on their achievement.

"It says it's even better if you gently suck the scrotum containing the testicles as if kissing it."

Odil, who had prior kissing experience, took the lead.

She playfully circled the gradually hardening balls with her tongue, then parted her bright red lips and took one into her mouth.

Odette, having seen her sister's skilled demonstration, also took the opposite ball into her mouth, pressing her nose close.

Thus began the Twins' double fellatio.

The excitement from the fact that a Witch of incomparable nobility was caressing his balls like a prostitute.

The sense of depravity from the fact that the two strikingly similar sisters were doing it simultaneously.

The physical pleasure felt within the hot, complex mucous membranes of their mouths.

It easily shattered Siwoo's patience.

It felt like his lower body was melting into a soft, gooey mess.

Along with the sensation of blood rushing, his cock began to grow vigorously.

Almost simultaneously, the Twins pulled their mouths away.

"Got it!"

"It got bigger!"The cock, unaware of its owner's turmoil, bobbed vigorously up and down as if begging for more.

Siwoo closed his eyes.

I don't know anymore.

Let's just enjoy it.

Honestly, how much had he been persecuted and mistreated in this city?

Let's just consider it a good experience.

If I get caught, I'll just die then.

"Fuck it, I don't know."

Once he thought that, his mind felt much lighter.

The reality that had been a hellish existence where he had to endure arousal from all sorts of stimulation transformed into a heaven he couldn't have bought with money in his previous life.

Was this what they called the skull-water of Master Wonhyo?

"Next is... Hmm, what does it say? Slooowly...!"

While Odette diligently licked the shaft to keep the thing she'd barely revived from dying, Odil continued reading the book.

"When a male's pleasure reaches a certain level, he discharges semen... I know this part. Is this how babies are made?"

"Slooowly... Yes, though we can't make one anyway!"

Odil, who was skipping the explanation about ejaculation thinking she already knew it all, gaped in shock.

A stream of curses poured from Odil's mouth, which had been acting so refined.

"Isn't this... isn't this completely insane?"

"Why?"

Odette, who had been resignedly watching Siwoo with a blissful smile, flinched. She looked at the page Odil was reading and was equally horrified.

Written there were the methods of proper intercourse between a man and a woman, with an illustration showing a man and woman intertwined and a close-up of their genitalia joined together.

The first shock was that the woman also had to take off her clothes and reveal all her shameful parts. The second shock was that such a large thing had to be inserted into the split between her legs.

It was a hole that usually made one wonder why it even existed...

"...This is a bit..."

"...Sister, I feel sick."

Odil's face turned pale, and beside her, Odette gagged.

Of course, they had no intention of trying sex themselves.

But they had at least wanted to attempt something similar, yet the truth presented to them was far too shocking.

"Insert the erect male member into the vagina, which secretes love juice, and perform piston-like motions. The ejaculated semen contains baby seeds, and when a baby seed meets an egg in the womb, fertilization occurs, followed by implantation. After 36 weeks, a baby is born..."

Siwoo, who had been about to let go of his sanity, barely managed to cling to his senses as the stimulation faded.

"Now you understand? Sex is an extremely obscene and lewd act. That's why it should only be done between people who love each other."

It seemed they understood the mechanism of ejaculation but didn't know everything about sex.

Seeing Odil and Odette so deeply shocked, Siwoo thought he could cleverly talk his way out and escape.

"May I go now? It's getting a bit chilly."

An emergency meeting unfolded before his eyes.

"What should we do, sister? We can't show our naked bodies to the assistant. How obscene."

"........"

They had learned from their Master that a woman's naked body was extremely important and must never be shown to a man.

That wouldn't change even if the man was Shin Siwoo, a mere slave.

"There's no other way."

Odil let out a deep sigh.

"Let's stop here for today."

"A wise decision!"

Siwoo, his restraints loosened, beamed with joy and tried to put on the underwear that had been hanging around his ankles.

The twins' saliva was still damp on his balls, but considering their beauty, it wasn't unbearably unpleasant.

"Wait!"

Just before Siwoo could pull up his shabby underwear completely, Odil stopped him.

"It feels a bit unsatisfying to end like this. At least let's see you cum."

"I agree."

"You always twitch and jerk when you ejaculate. I've always been curious about what it feels like then."

They hadn't done any direct penetrative sex, but if it became known that he had given such masculine sex education in this mansion, he'd be dead anyway.

A calculation formed in his mind: rather than clutching his aching lower abdomen and shuffling back awkwardly, it would be more beneficial to have a nice release while receiving a handjob from the beautiful twins.

Maybe they'd even use their mouths like before.

With an extremely Takasho-like thought, Siwoo comfortably lowered his underwear again.

"That's a great idea!"

Odil closed the book with a thud and approached Siwoo.

"Good, then I'll take it that there are no objections..."

"Lady Odil, how about this method? There's a way to observe the moment of male ejaculation very closely."

"Oh? Suddenly you're being very proactive?"

"Once this is over, I can return to my quarters."

Siwoo raised his head shamelessly.

If he was going to be used and abused anyway, and die whether he did this or that, he might as well feel good.

Siwoo dangled his cock out.
