Promised Various Positions
Jiyoung, who had been energetically pounding from above, conked out. I told her to switch positions if she was tired, but she insisted on the cowgirl position, saying the patient should lie down.
Moving on top gives the woman autonomy over the pumping, but it consumes extreme stamina. All I did was play the role of a cushion underneath.
As a result, Jiyoung stretched out like that and fell asleep. Even when I told her to wash up and sleep, she wouldn't budge. Seeing how her eyes had rolled back, I doubt she'll wake up until tomorrow morning.
Level: 4
Satisfaction: 1/40
Points: 17pt
The slave's level went up again. It seems satisfaction increases by about 10 every time I cum inside her. At this rate, Jiyoung's level will surpass mine within days.
'Was my libido always this strong?'
I quietly slipped out to the living room. I took out a cigarette I had set aside among the looted items. I can't remember the last time I enjoyed this special feeling of having a smoke after sex.
"How fast does recovery happen in the Slave House?"
I asked the empty air. The system, which must be watching from somewhere, only answers when asked, except for tips. Just like an AI.
[It will take time to fully heal, but about 3 days and there should be no hindrance to activity. Of course, as long as you're careful with the injured arm, you could even hunt zombies right away.]
I got the answer I wanted. I was planning to go outside and hunt zombies while Jiyoung slept.
My current level is 7. The system advised me to reach 10 before meeting the second slave candidate, so I still have a long way to go.
[Frequent sex with your slave will help you recover faster.]
Huh?
"What does sex have to do with recovery?"
[The Water's Protection skill has a slight recovery ability. It will help wounds heal. Of course, for severe injuries like fractures or amputations, you'll need an enchanter who specializes in recovery.]
So sex has a recovery effect. It really was all about sex from start to finish. What exactly does the entity that awakened me want?
[.......]
This bastard, who even reads my inner thoughts and answers, shut his mouth. This must be a core-related question too.
[The higher the slave's satisfaction, the greater the recovery effect. Besides this, satisfaction is used in various ways, so always pay attention to how satisfied your slave is. It doesn't end just because the master is satisfied.]
He didn't answer my question, but he gave me a useful final tip. Basically, as long as we're having sex, satisfy the slave to the maximum.
I picked up the crowbar and went outside. One arm is plenty for low-grade zombies.
Level: 8
Experience: 11/80
Points: 10pt
I went all the way down to the national highway and finally leveled up. Thanks to the increased EXP MAX, I received a good amount of points too.
I distributed them evenly among each stat, reaching 15 as the system advised.
■ Stats
— Attack/Defense: 15/99
— Agility: 15/99
— Sense: 15/99
Points: 1pt
The sense of elation from reaching a certain level was no joke. To the point where I wanted to wake up Jiyoung, who was sleeping without a care in the world, and shove my cock in.
I woke up and my lower half felt warm.
'What time is it?'

Looking down, Jiyoung was sucking my cock expertly. She's faithfully carrying out the command to wake me with morning fellatio.
I'm not sure if it's even morning right now, though.
"A-yeohi, juh-heun achim-imnida."
"You don't have to greet me while you've got your mouth full of cock."
She smiled bashfully and lowered her head again. Her technique of sucking hard and then releasing is top-notch.
Jjo-ook, jjo-ook...
Jju-weop jju-weop, jju-oo-oop
Buu-uk, buu-uk, bu-reuk, bu-reuk
My mind snapped wide awake as I unloaded satisfyingly into Jiyoung's mouth. Looks like today will be another energetic day.
Satisfaction: 11/40
Her satisfaction rose by 10 from one oral creampie (1 → 11). The fact that sex is a means of leveling up is a perfect match for the slave class.
"It's delicious. I haven't even eaten breakfast, but I'm full thanks to you, ju-in-nim."
"Don't talk nonsense and get breakfast ready. We're going out as soon as we eat."
"Going out? But ju-in-nim, you hurt your arm."
"I have to test the slingshot."
"Ah."
I need to know the power of the Water Slingshot. For that reason, when I was coming back yesterday, I diligently searched through the wreckage of destroyed cars.
I picked up a few parts suitable for a slingshot from the truck's toolbox.
"Um... how am I supposed to fight zombies alone? Your arm is like this, ju-in-nim, and if a scary monster suddenly appears...."
"I'll only test the weapon near the villa. Don't worry, one arm is more than enough for zombies."
"Yes...."
She was brimming with confidence yesterday, but now that she's about to jump into real combat, she's shrinking right away. I learned from my conversation with the system that sex is the medicine for times like this.

"When you become a slave, does your libido increase? A girl who was a virgin until recently seems to like my body too much."
[It's because of the Mark of Restraint. Once engraved, she reacts more sensitively to the master's body. She feels better and better each time, so she has no choice but to cling to you. It's best to embrace her frequently, as sexual communion with the master affects her growth.]
I got this answer. The reason Jiyoung gets heated every time she sees me was because of the mark.
[You don't need to be disappointed thinking it's artificial attraction. In the first place, a woman incompatible with Suho-nim wouldn't have been selected as a slave candidate. The mark is merely a tool to accelerate the bond between master and slave.]
The system even comforted me like this, worrying I might be disappointed. Honestly, I find it convenient.

"If we go out and work hard and get results, I'll give you proper sex when we get back. You want to try other positions now, right?"
She kept insisting on pumping from on top to be considerate of me, but that's only good for the first one or two times, and now it's gotten boring. Different positions stimulate different areas, but doing the same thing every time must leave you feeling like something's 2% lacking.
Her eyes immediately lit up, and she quickly studied my mood.
"But ju-in-nim, your arm hasn't fully healed yet. Other positions are too strenuous."
"It's fine. The more satisfied you are, the better it is for me too."
I told Jiyoung the tip the system gave me. When I said my recovery speeds up depending on the frequency of sex and the slave's satisfaction, her lips stretched from ear to ear.
"My usefulness has increased by one more! I've become a slave who's good for ju-in-nim's body."
She's making a huge fuss telling me to hurry and give her the slingshot. With this kind of energy, I think we'll get good results.
*
To start with the conclusion, it was a satisfying test.
"Ju-in-nim, this... how to use it just floods into my head. It's like someone next to me is teaching me."
As soon as she received the slingshot, she shivered slightly and said the method of using it just popped into her head.
A slingshot is basically just pulling and releasing, so there's no real need to learn how to use it, but what Jiyoung meant by "how to use it" was a kind of knack.
The know-how of using the slingshot—how far to pull it, how to adjust the angle, how to shoot far, how to reload quickly—was being drilled right into her head.
"It's not good to just pull it as far as possible unconditionally. The stance goes like this...."
She had become a skilled operator before I knew it, moving here and there, aiming all around. Her stance was so stable that I didn't even need to support her from the side.
The most surprising thing was the projectile.
When I held out the bolts and nuts I got from the truck and the round stones I picked up from the driveway, she grinned and opened her palm.
"Look, ju-in-nim!"
Water quickly pooled in her palm, then floated into the air and clumped into the shape of a bead. Water becoming a projectile shining like a glass marble—it was nothing short of amazing.
"How did you even know to do that?"
"It told me to concentrate and think of the shape I wanted to make. I tried to make a metal ball, but a water bead came out."
Because she's water-type, she made the projectile from water. Water's Rage wasn't just a simple combat skill. It could use area-of-effect attacks and, like now, directly create projectiles for her slingshot.
"Because my grade is low, I can only make one right now, but it said that as my grade rises, I'll be able to make several at once."
Just as the system gives me tips, it's also carefully instructing Jiyoung on the knacks for using the slingshot. So much so that there's no need for me to intervene myself.
"Gr-rrrl...."
Just then, two zombies could be seen loitering over on the other side. If we got closer, they'd charge to bite us.
"Can you shoot from here?"
"I think I need to get a little closer."
"Aim as you go, and shoot when you think it's good. I'll take care of one."
"Yes, ju-in-nim."
I didn't know what the cooldown for reforming the water after shooting was. Jiyoung said she'd have to try it to figure it out.
To draw their attention, I ran toward the zombies first. I put strength into the hand holding the crowbar so I could smash their heads immediately if she missed her shot.
Sswae-ae-ae-ae—Aaek—
The projectile flying from behind slammed into the head of the zombie coming at me first. It glanced off slightly, as part of its ear and cheek were blown away. If it had hit directly, its head would have been shattered.
It was a force hard to believe came from clumped water.
Kwajik—!!
While the creature was staggering from the impact, I crushed its skull followed immediately by the head of the zombie trailing behind it. This was to make sure I didn't interfere with Jiyoung's finishing shot.
Jiyoung calmly formed a second projectile. The delay was longer than I expected. It seemed tough to deal with multiple enemies at once until her grade improved.
The second projectile that flew out accurately smashed the zombie's head. With a heavy bursting sound, the zombie's body collapsed.
The first zombie hunt using the slingshot was a success.
[You have slain a zombie. Experience increased by 1.]
[Your slave has slain a zombie. 1 experience has been transferred to the master.]
