The First Lesson: Training the B-Rank Asset
If I threaten her with blackmail instead of opening her up, it would qualify as blackmail, right?
But that’s it.
Unauthorized Asset Damage is far more severe than blackmail.
“W-what? You mean you won’t open her up? Then what exactly are you planning to do with me?”
“There are plenty of ways. With the mouth. With the breasts. With the thighs. Or… with the ass.”
As my words continued, Min Cha-eun’s face gradually flushed red until the mention of the ass turned it deep crimson.
“Th-the ass?”
I flashed a wicked smile.
“Yes, the ass. As long as it’s not severely damaged, it won’t affect the grade. And I heard there are quite a few assets who enjoy that hole specifically… Have you never tried it, Manager?”
The horror on Min Cha-eun’s face went beyond words. She was clearly thinking, *Why didn’t I think of that?*
“You’ve never masturbated with the ass either?”
She shuddered at my words.
Her reaction was completely different from her usual cold demeanor, so my smile grew even thicker.
“Oh? Then I have a lot to teach you. In a month you’ll be able to use the ass too.”
She trembled all over, her face burning.
“But for a month, if you become my sex slave, I’ll delete the video cleanly. Kneel and take my cock. Agree?”
That was the deciding blow.
Her cold aura thawed, and her knees bent slightly.
She was probably still confused and lost inside.
I didn’t say anything more.
Sometimes silence is the strongest pressure.
Thus, a minute that felt like a year passed, and two minutes that felt like twenty.
Squelch.
Min Cha-eun’s knee slowly bent.
Midway.
“Are you really… really not going to open me? And you’ll delete the video in a month?”
“Of course. I’ll give you three chances to refuse. I’m giving you three chances even though you want to do it. If you don’t keep the promise…”
It wasn’t a real promise, more like a threat, but who cares.
Step by step. Grasp everything around Im Jun-sung first, then move to the next step.
That was my goal.
The dogeza that marked the beginning of it was just opening.
Squelch.
Kneeling, she placed both hands on the cold floor and pressed her forehead to the ground.

“I… I agree to become Han Jae-young-nim’s sex slave for a month…”
I frowned.
“You call me Master. And be more respectful. As an asset, you must know the proper way to submit, right?”
“For a month I will become Master’s sex slave and serve with all my heart and soul.”
She lowered her upper body further and pressed her forehead to the neatly folded hands.
Her shoulders shook, showing how hard she was trying to endure the humiliation.
“Good. Then today is the commemorative first day. Let’s start with the blowjob.”
Squelch!
I quickly lowered my pants and pulled out my cock.
Min Cha-eun’s head shot up.
And the eyes that I thought would be filled with tears were now wide open and sparkling.
As if she had been waiting for this all along.
“A blowjob is my first time, Master.”
As expected of a B-rank asset, once she swore to submit, she adapted naturally, as if she had always been a sex slave.
I had only heard that such submission etiquette was one of the tests for each grade, but seeing it in person, the effect of the training was immense.
*I’m the one who’s embarrassed. I need to adapt.*
I had become the master. How long could I keep calling her “Manager” and using honorifics?
“B-rank, you must have had some training with blowjobs and paizuri, right?”
Her eyes sparkled even under my command, fixed on my cock.
“I practiced theory and models… but since I never had a real owner before, I never tried it.”
This was even more surprising.
“So you didn’t open her mouth or ass. You just practiced without opening?”
“…!”
Her blue eyes were stained with contrast against her flushed face from my crude, vulgar words.
“Then it’s time to put what you learned into practice. Heh heh.”
My 21 cm cock swung in front of her.
Min Cha-eun, staring at the swaying cock, slowly approached.
“Follow what I taught you. Suck it.”
Since it was her first time, her voice was a mixture of fear, curiosity, and expectation.
“Then I’ll begin.”
She slowly reached out and gently gripped my cock shaft.
“This… is a man’s…”
“How is it? Feel it for yourself.”
“It’s warm. Haa… haa… and it’s hard yet soft. Haa…”
Even just holding the shaft, her breathing grew rapid.
“Put it in your mouth.”
She had to learn everything from the beginning, so there were many things I knew only theoretically.
*My porn career is five years!*
From the age of fifteen, when I started watching porn with my father’s resident registration number.
Now was the time to put into practice what I learned from porn, not just in imagination.
*Five years of masturbation, five years of porn. Ten years in total. Don’t chicken out.*
Her lips slowly came closer, and my tension rose.
What would a woman’s mouth feel like?
It should be different from my hand.
*No, what if it’s the same?*
Everyone said it’s different.
But I couldn’t show any of those worries.
I was her master for a month.
And to turn her into my cock’s slave in a month, I had to show no hesitation at all from now on.
Pretend to be inexperienced though I was.
“Haap…”
Her mouth opened, and my glans entered.
The feeling of tongue and lips made adrenaline and dopamine surge to the top of my head simultaneously.
“Ugh.”
Even though I just put it in without doing anything, I let out an involuntary breath.
“Are you… in pain?”
She pulled my glans from her mouth with a startled look and looked up at me.
“No, continue.”
Nodding slightly, she took my glans back into her mouth.
And slowly began moving her tongue.
The feeling of wrapping and licking the glans was felt in every cell.
Min Cha-eun had been moving only her tongue, but slowly started sucking.
At first she was careful, pressing the underside with her tongue tip, then added pressure with her lips, creating suction that drew out the warmth of the glans even more intensely.
Her breathing quickened, and her nose brushed against my lower abdomen.
“Eut… s-suck, mmm…”
Gradually her lips tightened more, her tongue sweeping the shaft, and her tongue tip wrapped and swirled around the glans.
A heat, whether of shame or excitement, flowed down her entire neck and collarbone.
I wanted to go deeper.
I wanted to feel the deepthroat sensation, not just the tip, but all the way to the back of her throat.
I grabbed her head and slowly pushed my hips forward.
“Eup!! Eup! Suck!”
I hadn’t gone in much, yet her eyes widened as if she had reached her throat.
“Eup!!”
Her voice was muffled in her throat.
Saliva dripped from the corner of her mouth, and my cock pushed deeper.
Thud, thud, thud!
Min Cha-eun urgently tapped my thigh with her palm.
She couldn’t breathe properly because of the foreign object forcibly invading her throat, her face looked about to burst from being completely flushed.
“Endure.”
But unlike her wish, I ruthlessly pushed deeper.
“Kek! Kek! Kuuu…”
Only when strange sounds came out did I finally pulled out.
“Kuulak! Kuulak!”
She coughed up, saliva spilling everywhere.
“Uek… ek.”
Watching her struggle with dry heaves, I remembered the way she had looked down at me that morning with eyes full of contempt.
“That’s enough. Open your mouth.”
“Kuulak, j-just a moment…”
But I didn’t wait.
I grabbed her hair and pulled.
And shoved my cock into her wide-open mouth.
“Kuk! Kuk kuk!”
Her throat, unprepared for penetration, tightened instantly.
*If I’m not careful, the throat might tear. I need to give her time to adapt.*
In this situation where barely a third was in, forcing it deeper could be disastrous.
It was dangerous to simply ram a 21 cm thick cock into an untouched throat.
“Kuulak kuulak! Just a moment… kek kek!”
Seeing her cough and dry heave again when I pulled out, I smirked.
“Suck again.”
Min Cha-eun moved closer to my cock even while struggling, and began sucking with strong pressure that made her cheeks hollow.
