City of Witches Chapter 13

Even I doubted where such courage came from after saying it.

I had never really thought about how I had lived my life being swayed by sexual desire until now.

But now, something was different.

I didn't know if it was the backlash of the pent-up resentment I had suppressed all this time manifesting as sexual desire, or if it was a sense of resignation after giving up on everything.

"Like this?"

The position Siwoo suggested wasn't particularly special.

Odette below, holding Siwoo's thing in her mouth, and Odil using her hand to jerk him off.

It was a position that made efficient use of the Apprentice Witch sisters.

"Yes, if you take this position, Lady Odette can feel the throbbing pulse of the testicles writhing as the cum flows through the urethra, and Lady Odil can learn the texture of the male member."

"Hoh, sounds plausible. You're smart, Assistant?"

"You flatter me."

In a way, it was a despicable act.

I also felt a pang of conscience, thinking I was deceiving the ignorant sisters and doing something wicked.

But then again, I thought, what the fuck, did I do anything wrong first? They were the ones who wanted to start this in the first place.

"Odette, are you ready?"

"Mmhmm!"

Odette, holding a towel and nodding her head like an excited dog, had Siwoo's testicles gripped between her lips.

"I will teach you a technique not covered in the textbook for easily making a man ejaculate."

"There's such a thing? Well, you are a man too, Assistant."

"First, Lady Odette, please slowly kiss the testicles like you did before."

"Got it! Mmm...."

A pleasure so intense it sent shivers down my spine.

Above all, the sight of Odette's face in my downward view was unfairly beautiful.

Her face half-covered by my cock, licking my balls intently.

Moreover, her older sister was sitting right beside her, learning how to please a man, which tickled a strange sense of immorality.

"First, shape your hand like this."

"Like this?"

Odil showed her hand, making a circle with her thumb and index finger like an 'OK' sign.

"That won't do. Since Lady Odil has small hands, please make a ring with your thumb and middle finger."

"Okay."

Odil followed Siwoo's instructions with a serious expression.

Her dainty hand formed a perfect circle, ready to stimulate Siwoo's cock at any moment.

"Next, we use saliva as a lubricant."

"Saliva?"

"Yes, it allows for much smoother stimulation than using a dry hand."

"But wouldn't that get a lot of saliva on my hand?"

Siwoo looked at Odil and declared confidently.

"It's common knowledge that a woman's saliva is the best lubricant."

"Wh-what? Okay, fine. Why are you being so serious all of a sudden?"

The current Siwoo felt no guilt about deceiving the innocent Apprentice Witches.

Odil let out a stream of saliva onto her palm.

Even the way she spat was elegant, a testament to the beauty bestowed by her Witch lineage.

"Now, insert the male member into the center of the ring and slowly start moving it back and forth."

"I know, I saw Professor Amelia's demonstration, right? Like this?"

Siwoo's already fully erect cock pushed its way into Odil's white hand.

"Wow, it's incredibly hard and hot."

"Thank you."

"Huh? When did I compliment you?"

Her hand, with blue veins visible on the back, began moving up and down.

Odil's eyebrows cutely furrowed together.

From observing the previous lesson, Siwoo knew Odil had a habit of furrowing her brows when concentrating on something.

-Squish squish squish

The younger sister on the balls.

The older sister on the cock.

This might not quite be a 'sister double' yet, but wasn't it at least a 'sister mini-double'?

Odil's palm felt particularly warm, perhaps her body temperature was higher than Siwoo's.

With the added saliva, it felt so good, as if his lower half was soaking in a bathtub filled with pleasure.

Then, Odette, who had been fumbling with the balls, suddenly looked up.

She must have found the sight of her older sister enthusiastically pumping away quite amusing.

"Slurp... Sis! I wanna try too!"

"No, you have to use your mouth from below."

"That's so unfair! Where's the fun in that?"

"You should have said something before we started if you were unhappy."

The Twins suddenly started fighting, each grabbing hold of the cock.

Worried it might break, Siwoo hastily stepped in to mediate.

"How about we do it like this instead?"

Hearing Siwoo's words, which had gained persuasive power since the middle of his sentence, the Twins pricked up their ears.

"Each of you does 30 strokes with your hand while continuously changing positions."

"Too bothersome."

"The Assistant is right! That's the fair way."

Odil refused, showing no interest in a proposal unfavorable to her, while Odette complained of unfairness.

After a brief squabble, the Twins quickly reached a conclusion.

"Fine, then we'll just take turns once each. I'll go first."

There was no need to limit such a fun thing to just one turn each.

That was the Twins' conclusion.

Odil and Odette resumed their previous formation.

With nothing else to worry about, they fully immersed themselves in their respective roles.

"How is it? Does it feel a bit rough?"

"You don't necessarily need to move all the way to the base. A man's erogenous zones are concentrated in the glans area."

"Ah-ha? Is that so?"

Though they seemed immature and foolish, neither Odil nor Odette were stupid girls.

A fool could never become an Apprentice Witch in the first place.

Moreover, if they were talents selected as successors by the Countess, who was no ordinary Witch, they were highly likely to be the kind called geniuses.

Perhaps that's why Odil quickly grasped what she had been taught.

An ecstasy incomparable to doing it alone surged through him.

"Clear liquid is gathering at the tip. Is this cum?"

Odil, who had been moving her arm, made eye contact with the glans and asked.

"No, this is called pre-ejaculate. It's a kind of cleansing fluid that cleans the urethra before the cum comes out."

Siwou answered based on common knowledge, and Odil nodded her head as if she had learned something new.

I've been thinking for a while now, wouldn't it be easy to take advantage of these Twins?

Their innocence, separate from their intelligence, might prove useful in the future.

Such stray thoughts were brief, as the feeling of impending ejaculation slowly rose.

Honestly, I thought it was impressive I had held out this long.

"Lady Odil."

"What? Does it hurt? Your face is all scrunched up."

She said that, but she seemed to have already guessed.

Well, she must have seen the unsightly expression a man makes at the moment of ejaculation several times by now.

But the reason Siwoo suddenly spoke to Odil wasn't just to inform her of that.From now on, the action I was about to take would serve as a litmus test to gauge just how far I could push the line with Odil.

"Haven't you already witnessed the scene of ejaculation numerous times until now?"

"That's true."

"Then, how about trying a slightly different method this time?"

"What kind of method?"

I took a brief breath to hide the fact that I was nervous.

"Receiving the cum with your mouth."

The movement of the hand I felt from above and the flickering of the tongue from below grew distracted.

She was probably pondering why I had made such a suggestion.

"I know the main component of cum is protein, so it shouldn't be harmful to the body. And tasting its flavor and scent is also part of observation, right?"

"As expected, you are the wise Odil-nim."

"But Assistant Siwoo said that if you put a man's cock in your mouth, germs could be transmitted!"

Odette, who had been diligently crawling under my legs and licking my balls, had a slight sheen of saliva on the tip of her nose.

I already had a prepared response for that.

"The pre-ejaculate fluid has passed through and completed sterilization, so there should be no problem."

I wasn't sure if pre-ejaculate fluid actually had sterilizing properties, but the Twins probably wouldn't consider it that important if their curiosity got the better of them.

"Not a bad suggestion. Alright. What do I need to do?"

"Just keep moving your hand as you are now and take the glans into your mouth."

"Got it. Ugh, it's kind of salty?"

"Don't worry, it's pre-ejaculate fluid."

Finally, the cock that had been writhing tormentingly in Odil's hand entered the sanctuary of her small mouth.

It was hot, just as she had fully savored my balls earlier.

Her tongue, moving as she spoke, writhed and caressed Siwoo's cock.

"Like thith?"

"That's right. In that position, just move your tongue very slowly."

Odil obediently kept the glans in her mouth and diligently moved her hand.

A tongue licking the round glans in circles, as if melting a candy.

The Witch City, Gehenna.

It was a good thing I got caught.

For a very brief moment, that thought crossed my mind.

Since I was already on the verge of ejaculation, unfortunately, there was little time to savor Odil's moist, warm mouth.

"You can just stay still like this."

Siwoo's member began to throb.

Along with a massive wave of pleasure, as if surging from the deepest part of my being, a very thick stream of cum shot into Odil's mouth.

-Gulp gulp gulp

"Ugh...???!"

Perhaps she hadn't anticipated such force?

Odil's eyes widened in surprise as intermittent spurts of cum struck her uvula, a baptism of semen.

Her hand had stopped moving too.

"Huh."

An exclamation escaped me involuntarily.

Although she wasn't sucking on the glans or moving her head.

It was merely an ejaculation while feeling the movement of her tongue, but it felt better than any ejaculation I had experienced so far.

Siwoo's body trembled as he shot every last drop into Odil's mouth.

Odil, with her mouth filled with cum, pursed her lips and puffed out her cheeks.

A drop of cum that hadn't been fully contained in her mouth peeked out near her lips.

Odil, who had been grimacing with a look of disgust, took out a handkerchief and spat the cum onto it in a stream.

"What is this?"

Anger flickered in Odil's eyes.

I had never imagined it would taste like this.

Since it was white and sticky, I had even expected a bit of sweet, milky flavor.

But the taste was far from any expectation.

"How is it? Unnie, what does it taste like?"

Odette, who had been observing the repeated contraction and relaxation of the firm balls, urged her unnie, who had tasted cum for the first time in her life, for her impressions.

But Odil still wore an irritated expression.

"If I had known it would taste this bad, I wouldn't have agreed to do it!"

However, Siwoo remained unblinking and calmly persuaded Odil.

"I merely made the suggestion to provide you, Odil-nim, with the best possible observation conditions. Above all, as a male, there's no way I could have tasted my own cum."

"Well, that's true..."

Fortunately, Odil wasn't a petty Witch who would unreasonably get angry just because she felt displeased.

"Ptooey! Still, it's a taste I never want to hold in my mouth again."

Odil, placing her hands on her hips and fuming, unaware that cum was clinging to the side of her lip.

"Me too! I want to try it too!"

Odette, who had scurried up, promptly took the glans, still smeared with white cum, into her mouth.

As the sensitive glans, heightened post-ejaculation, entered Odette's mouth, it throbbed and squeezed out the remaining cum in the urethra.

"Ugh...."

Odette's face also contorted similarly to Odil's.

Having never tasted cum before, I couldn't imagine the flavor, but it likely wasn't pleasant.

"Then, it's Odette-nim's turn now."

"Huh? Um... I'm fine."

Odette, having already tasted the cum, responded lukewarmly.

"That's a shame. I thought both you and Odil-nim should experience this equally. Otherwise, wouldn't only Odil-nim have expanded the horizon of new knowledge?"

Odette seemed to catch onto something from Siwoo's smooth, flowing words.

Only unnie knows, and I don't?

It feels like I'm losing somehow.

"Assistant Siwoo, I'll do it. Even if the taste is a bit off, I'm still curious."

"Odette, you'll regret it. Stop."

"No! Unnie always tries to have all the fun by herself."

Siwoo had subtly tapped into Odette's psychology of wanting to follow and compete with whatever her unnie did.

Still, having observed from the side for two years.

Handling the Twins, who had childish aspects, was a piece of cake.

"W-well, if that's the case, then I suppose there's no helping it."

As if she had no real intention of stopping her, Odil took the scrotum that her younger sister had been sucking on into her own mouth.

A short while later.

"Uweeeek! It really does taste bad!"

I fairly coated Odette's mouth with cum as well.

With Odette making a tearful face and stomping her feet, today's sex education class came to an end.
