Chapter 37. Training Ymir (1)
Yumir.
I doubt you could possibly imagine just how long I've waited for this moment.
No—every man alive has probably waited for this moment.
The moment I finally crush that sky-scraping pride of yours, and let my hands roam over the body you yourself could never be bothered to cultivate.
-Squish.
Yes, the instant those voluptuous breasts—forbidden fruit, until now only to be looked at—are finally cradled in my hands.
Even when she offers no real resistance, the thrill of victory still courses through me, loud and clear.
"......."
Yumir just stared down at the hands fondling her breasts with a blank expression.
Though one might expect an unconscious flicker of revulsion, I couldn't catch a single reaction from her.
Knowing her personality, maybe she's incapable of sexual shame from having her breasts groped...
-Squelch.
But what about down here, where no one's ever laid a finger?
"...Ngh."
I immediately pushed her legs apart and shoved a single finger inside. A moan slipped from her lips.
Unbelievable tightness. Even with just one slender index finger, the pressure made my joints ache.
I thought she was just some idiot with big tits, but this place is no joke either.
"Ngh, hngh!!"
But that intense tightness also meant she was utterly unaccustomed to this.
Yumir's expression crumpled, and a pained moan leaked from her mouth.
"Have you never even touched yourself?"
"N-no, no. I've never done it."
"I doubt you're completely devoid of sexual desire."
"......Because it's revolting."
"Revolting?"
"A friend."
Had I triggered some kind of trauma with that question?
She averted her gaze and raised a hand to her own mouth, answering with obvious difficulty.
"I once witnessed... the only person I ever considered a friend... being violated right in front of me...."
"......Ah, I see."
A friend....
If she was her only one, she must have treasured her deeply.
I could understand it immediately, since I've had a similar experience myself.
Watching someone precious get violated before your eyes.... It's only natural to feel utter disillusionment after witnessing something like that.
Of course, in my case, unlike hers, it became a threat to my survival, so I put my abilities to vigorous use regardless, but anyway....
"...Mentally, she's the complete virgin, isn't she."
If I want to use her properly, I'm going to need to spend a good long while training her.
Sure, if I intended to use and discard her immediately, a woman who's already finished would be more convenient. But Yumir was an existence I coveted even more than Serika.
Serika has the potential to grow into a being comparable to a future Demon King, but in the end, what she wields is "her own power."
Yumir, though, is an amplifier who can directly boost "my power."
I could feel it through the subtle changes in my body after taking the drug she gave me.
-Wooong.
No, not subtle—I could feel it distinctly.
A faint tremor echoing throughout my body. The resulting pressure left me feeling just a little stiff and sore.
It's a phenomenon that occurs when enough mana gathers in the body to form a circle. Beyond that, my mind felt a little sharper, my heart more at ease—suggesting the potion she gave me also had a mentally stabilizing effect.
"......Has my ability changed as well."
The crucial part is what kind of change happened to this power.
I quietly met Yumir's eyes and called her name.
"Yumir. Before I properly violate you, I'm going to ask a few things."
"Y-yes, please, ask."
Perfectly obedient.
Good, questioning her won't be a problem.
"Was the only effect of that potion you gave me simply to help temporarily create a circle?"
"......Do you require a detailed explanation of the principles involved?"
"Yeah, go ahead. Explain it."
"Very well, then...."
-Squelch.
I propped her upper body upright and thrust my ring and middle fingers into her cunt.
"Hnkgh!"
"I commanded you to explain."
Ignoring her moans, I spoke firmly. She looked at me with an unsteady gaze, then bowed her head and answered.
"...Ah, understood."
The moment her reply reached my ears, my fingers began rooting around and advancing inside her secret cleft.
Good, she can still talk while I caress her. And she's not all that sensitive yet, so she can endure the sensations and explain at the same time.
"One of the facts uncovered through my research is...."
Having assured myself of that, I got started. Soon, she began speaking to me in a strained voice.
"Mana is, fundamentally, an energy that the human body has great difficulty accepting."
"...Hard for the body to accept?"
"Yes. The human consciousness has many factors that interfere with the reception of mana...."
-Squelch, squelch.
"Ah, h-hic...!"
"You should continue your explanation."
I caressed her inner walls again and kept listening to her explanation.
To summarize: mana is energy that reacts to a person's will to produce physical force. And "will" is a concept that is very difficult to apply in a single, focused direction.
I could understand that to some degree even without being versed in magic.
No matter how deeply you concentrate, your subconscious and lingering stray thoughts are ceaselessly disrupting that focus, and merely excluding those requires tremendous effort.
"...So, from birth, it's impossible for a human to perfectly control the power mana holds?"
"That is correct.... Ngh!"
A moan slipped out as Yumir answered.
The moment I felt her initially tight pussy grow even slightly wetter—
So she's not actually frigid. It was just her trauma that made her feel revulsion.
"Then what about a witch? Does a witch who's accepted demonic blood wield magic better than an ordinary human?"
Hoping it might get a little easier to slide inside, I kept probing for her weak spots.
"...A human who has accepted demonic blood."
Even in the midst of that humiliation, Yumir kept her legs spread and continued her explanation.
"Fundamentally... becomes a being ruled by their desires."
"...Desires?"
"Yes. Mana is energy that responds to will. In other words, the clearer the subject's desires, the better they can utilize its power. And the demon race are, from birth, beings who remain utterly faithful to their own desires...."
-Squelch.
"...At least, on a conscious level, they can wield mana far, better than, humans...."
Yumir's explanation began to tremble as soon as I brushed against her inner membrane.
In that instant, I couldn't really hear what she was saying either. That flesh, webbed together all along the vaginal walls....
My finger had touched what is commonly called the hymen.
"...So in short, the potion you gave me is, at best, something that stimulates the mind and clarifies a person's will?"
I have to handle this carefully.
I risked my life to obtain the virginity of an Archmage. I can't just break something this precious with a mere thrust.
"Yes. Because it is a highly volatile effect, its efficacy is not permanent."
"......Just hearing that, it sounds no different from coffee or a narcotic."
"It is merely more potent and difficult to produce. The end result is similar."
"......."
In the brief moment of hesitation I had before continuing to caress her—
The thought "So it was all because of power built on such a trivial principle" flickered through my head, but even that I dismissed as water under the bridge and let it vanish.
No matter how pathetic the principle, before it's known, no one is actually aware of it. The unknown is something both the Demon King's Army and humans would fear alike.
So whining now about what happened back then would be a fool's errand.
"......How is the contract between a witch and a demon formed?"
Or perhaps some lingering attachment remained?
As if acting on a whim, I asked the question. She let out a ragged breath and answered.
"I can only speak theoretically, as I have been unable to secure a sample of a demon... but, in my personal view, I have judged that the demon race is, to some degree, similar in nature to insects."
"Insects?"
"Yes, the pheromones that insects emit.... By means of something analogous, demons can, interfere with the minds and bodies of humans who carry their blood, and control them at will."
Pheromones....
I didn't think it was entirely without merit. In truth, demonic creatures are, without exception, like something that crawled out from under a rock.
Just look at that bastard Belzebub, one of the commanders among the Demon King's Army executives. The guy literally has a fly for a head.
"Then, does this ability I possess also operate on the same principle as demonic pheromones?"
His ability was in a league of its own compared to mine—a large-scale mental interference power that could mercilessly crush the minds of an entire crowd.
"Most likely, I believe that is the case...."
"Then is it possible that the potion you gave me could also strengthen this ability?"
"Yes, it is. By ingesting an elixir refined and distilled from components analyzed from a witch's blood... if it clarifies those properties...."
-Squelch!
"...Ah, hngh!"
The moment my finger, having avoided her hymen, pressed against a certain spot—
Severely stimulated, her body began to tremble violently.
"Haah, haah...."
Yumir stared at her own genitals with tear-glossed eyes.
I pulled my fingers out briefly and saw a sticky liquid had faintly moistened even my palm.
Yep, right there. Found your weak spot.
"In that case, if I took more of your potion, what kind of effect would my power receive?"
Having pinpointed it, and intent on giving her a thorough caressing, I pulled her body into an embrace from behind and groped her breasts with my free hand.
The nub at the tip of the sagging mound of flesh slowly began to stiffen.
As her face flushed red, the moans flowing from her lips grew visibly thicker, clearer.
"If I may offer my thoughts.... In the case of a subject already under hypnosis, I believe you would be able to simultaneously interfere with multiple targets without needing any further specific conditions."
"...Multiple targets at once? Ones I've already dominated before?"
"Because you can reduce the waste of power needed for interference. It is also easier to exploit the mental gaps of a subject who has already received your pheromones once, thereby lowering the total output consumed."
Now this was a bit surprising.
Even if it's limited to targets already placed under hypnosis, being able to hypnotize multiple people at the same time. Doesn't this effectively ease the restriction that I can "only affect one person"?
"Furthermore, not only dominating the body and mind... but also controlling their senses, and if possible, even their memories...."
The explanations that followed were just as shocking.
Until now, I'd barely been able to suppress their consciousness. But to control their senses and even their memories? If used well, doesn't that mean I wouldn't even need to spend that much time on training?
"Ah, aah. Haah."
I only considered pressing for more detailed answers for a second. Her body, already teetering on the edge, suddenly quaked rapidly, and her limp hand began creeping toward her own mouth.
There it is. She's about to climax.
I immediately drove my fingers into her most sensitive spot.
"Ngh, oh, ooooh...!!"
The moment her body convulsed and a fountain gushed forth—
The liquid that spilled from her most precious place soaked into the bedsheet, and then, strength drained, she leaned her back against me.
Probably the very first climax of her life.
Her head slumping against my shoulder, a dazed, unfocused light began to gleam in her eyes.

".....Oh♥"
Damn, so even the Grand Archmage can make a face that undone, huh?
Feeling a surge of sadistic glee at the sight, I pressed a kiss to her cheek and then let my lips trail toward her ear, whispering.
"How do you feel?"
To ask her how her first-ever climax felt.
