The First Slave

How many times had I come inside Sujin? Her pussy was a monstrous thing—something that couldn't possibly belong to the same species as me. It felt like it existed for one purpose only: to wring every last drop of pleasure out of my body.

"Haa...! Haa...! Haa...!"

Sujin lay beside me in a wrecked heap, gasping for breath. Even she, who'd been endlessly begging for more of me, had finally run out of stamina. The enhancement from Power of Sex had clearly taken hold in her as well. Without it, there was no way she could have endured a session that had burned through stamina on the level of a marathon.

I checked the clock on my phone. A full six hours had passed. That was a stretch of time that would leave an ordinary person exhausted just from walking. I'd lost count of how many times I'd ejaculated. I pressed my heavy body against hers.

"Haaang...! Haaang...! Haat~!"

The moment I gently stroked the small of her back, she let out a fierce moan. She'd gone hypersensitive past her limits. If I drove my cock into her again, she might actually pass out. Of course, my own cock was already dead—I didn't have a shred of energy left to thrust into her anyway.

I gazed at her with tender eyes. She was impossibly lovely. The thought that I'd made this woman mine alone sent a satisfied laugh bubbling up. Anyone in this situation would have failed to hold it back.

Sujin tilted her head at my smile, looking puzzled.

"Why...?"

Fatigue she couldn't hide colored her voice. Had I tormented her too viciously? Excessive pleasure always turns into pain. Of course, Sujin had taken my cock because she wanted it, so she probably hadn't felt it as suffering—but she'd clearly pushed herself far past her limits all the same.

My emotional brakes had failed, and I'd driven her this far. Then I remembered: as long ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠as I had Power of Sex, overdoing it was actually a good thing. This wasn't just for my pleasure—it was for Sujin's sake too.

The moment I thought that, the tiny scrap of guilt that had poked its head in—no bigger than a baby chick's tear—melted away like snow. I really was a simple man.

"Because you're beautiful. Heh. I still can't believe this luscious body of yours is my personal lust-disposal unit now."

I grabbed her ass roughly as I said it. I'd deliberately mixed in vulgar language, but Sujin only flushed slightly and didn't call me on it.

She was already dyed in my colors down to the marrow of her bones. It was the combined result of my planning, the power of Power of Sex, and the lewd nature she'd always carried inside her.

"Hearing you say that is a little embarrassing. Hehe..."

She expressed embarrassment, but she didn't hide her joy. I caressed her face with a loving hand. She nuzzled into my palm like a baby. Warmth radiated from her skin. Maybe because we'd just had sex, her body temperature felt far higher than a normal person's.

Her reaction confirmed it. Sujin was now my perfect toy. Even if I ravaged another woman right in front of her, she wouldn't deny me or refuse. Even if her reason tried to make that judgment, her body was too deeply addicted to the poison that was me.

Sujin would become my precious collectible. Owning beautiful collectibles was wonderful, but I had no intention of being chained to any one of them. That didn't mean I was going to neglect her. It just meant I wasn't going to live looking at Sujin alone.

The world had no shortage of beautiful women. If I could, I wanted to make every last one of them mine. It was an absurd dream that even a childish kid wouldn't bother having—but with the power of the Unix Cube, it didn't seem impossible.

"Really, Sujin. You're the best. Your pussy. Your ass. It's like they exist solely for my cock."

"Heeh.... Thanks for the compliment."

To take dirty talk like that as a compliment. She really did have a talent for being a slut. Or maybe my training had just been that outstanding. Personally, I figured it was both.

"Anyway, let me confirm it one more time. You're mine now, Sujin. You'll do as ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I say, and whenever I want it, you'll spread your pussy for me anywhere. I don't want to hand you over to anyone."

The part about not wanting to hand her over to anyone seemed to please her; she nodded lightly, her face flushed red. I could feel that her body and heart had passed over to me completely.

I wrapped my arms around Sujin's voluptuous body. Today was Saturday, so I could stay home all day. Sujin didn't go to work on Saturdays or Sundays either.

"Mmm... I'm sleepy..."

Maybe because the energy drain had been too severe, Sujin fell asleep almost immediately. Or maybe my embrace was just too warm. I carefully lifted her sleeping form onto the bed, then checked the notification window. Something had popped up earlier, but I hadn't looked at it closely.

"Hm? Add as a slave? Ah, right. Come to think of it, one of the effects of Power of Sex was enslavement. I left it alone because I didn't know exactly what a Defeat Orgasm was—did that just trigger on Sujin?"

I pictured Sujin's face and tried to work out what a Defeat Orgasm actually meant. The window had appeared the moment she climaxed while declaring that she would offer me everything and become my thing. In other words, a Defeat Orgasm wasn't simply about pleasure—it was a climax that included the other party's complete mental surrender and submission. Thinking about the words themselves, that meaning seemed certain.

"So if I extract a partner's perfect mental surrender, I can enslave them. Enslavement, though.... What exactly does that even do? Well, obviously I'm making Sujin my slave."

The moment I answered the notification's prompt, a new change bloomed across my vision. Among the cluster of tabs packed along the right side, a new one had appeared: Slave Management. It sat just below the Quest tab. At the same time, two notification windows materialized. Both of them were nothing but good news for me.

I tapped the Slave Management tab and checked the contents.

It was basically similar to my own status window. The only real difference was that she had no Credits of her own.

What caught my eye were her stats and her ability. Sujin's numbers weren't all that far off from mine. Her Luck was a bit lower, but her Intelligence was far higher.

Some of that would have risen because of the sex with me, but if she hadn't possessed considerable stats to begin with, the numbers never would have climbed this high.

"Stats aside, the important thing is the ability."

Berserker Time. That was her ability. Next to the Ability heading, though, the word Locked was displayed. She hadn't liberated it yet.

That confirmed one of the hypotheses I'd been working with. What people thought of as abilities were actually skills. Or maybe genuine abilities existed too—but either way, the majority of what people believed to be abilities belonged in the skill category. Things like Fire Control, Water Control, and Earth Control were all in the domain of skills.

Of course, as I'd thought before, this kind of classification didn't matter much to me. I wasn't going to publish a paper on it. Still, holding information that other people didn't know was a considerable source of power.

The Locked notation on Sujin's ability nagged at me. If that locked ability were liberated, it would mean she could wield multiple powers the same way I did. Her ability, Berserker Time, was a power with tremendous effects. If she intended to become a Dungeon Hunter, that ability would be a huge help.

I still don't know much about unlocking abilities, so I'll leave that for later. For now, I need to learn more about this Slave Management.

The moment I thought that, several notification windows appeared in front of my eyes.

Looking over the Slave Management tab more carefully, I found a Call button and a Summon button. These seemed like fairly convenient features.

"Gah! Why is it so expensive? A thousand Credits for a call? That's insane. I'll just use a regular phone. And what's a 'worldline,' anyway? This thing ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠is stuffed with explanations I can't make sense of."

I'd already known the explanations were unfriendly, but this one was especially so. The one thing that came through loud and clear was that the costs for calling and summoning were enormous. At this rate, the features were no different from decorations.

Slave summoning, at least, seemed like something I might actually use in a specific situation. Calling simply didn't add up.

"Then again, even a call could be useful in an emergency. Say Sujin and I were in a situation where we couldn't reach each other on our phones."

It would probably come in handy during combat. I closed the Slave Management tab. Watching Sujin sleeping softly, I turned over what came next.

First, I would go to the Hunter Association and apply for Hunter registration. I'd apply for Dungeon Hunter registration at the same time. And of course, I intended ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to take Sujin with me.

"Sujin's completely surrendered to me and become my slave. So it should be fine to reveal a little of my power, right?"

If she suddenly became strong enough to pass as a Dungeon Hunter without ever training, she'd definitely find it strange. At first I'd thought up some rather forced excuse to convince her. But now that things had come this far, it seemed fine to just tell her the truth.

Of course, I wasn't going to open up about everything. I'd just explain that the ability I possessed was something quite special. There was a lot even I didn't know about the Unix Cube, after all.

How would her face change when she learned she could become a Dungeon Hunter? She'd be moved, surely. I wanted to capture that look in a photo too.
