Chapter 009: Weighing Big Sis’s Pregnancy Probability Against My Life

I opened the small bag and took out the pill.

“35%… probability…”

35%. Roughly one in three. One out of every three times. It’ll be fine, she won’t get pregnant that easily… No!! If Big Sis doesn’t get pregnant… my life is over!! …Damn it!

The hand holding the pill was already moving toward the cup full of cola. This tiny pink pill was worth the same as my life. Right now, I was holding my own life in my hands.

“My hand… is shaking… If I accidentally drop the pill into the cup…”

This wasn’t on purpose. I just wanted to reduce the guilt even a little. Because… my life was at stake! I had no choice!

My hand was already above the cup. All I had to do was drop the pill into the cola with my thumb and index finger… It was simple.

“I can’t stop my hand from shaking…”

“Pizza~ Pizza~ Time to eat pizza~♪”

Big Sis was already here! I had to do it quickly! Huh? The pill that was on my hand…? Did it fall into the cola?

“I’m thirsty. I’ll drink first.”

Big Sis picked up the cup and chugged the cola in one go.

Gulp… gulp… gulp…

Her throat moved visibly. She was definitely drinking it. Along with the pill…

Gulp… gulp… gulp… “Haaaaah~ Cola after work is the best. Yuuya, pour me another one.”

“O-okay.”

I took the cup from her and looked inside. Nothing… She really drank it.

“Why are you staring at the cup? Haha, you’re imagining something perverted using the cup I drank from, aren’t you~? Bad boy, Yuuya. If you become this much of a pervert as a kid, you’ll be in trouble as an adult. Hurry up and pour the cola.”

“I-I wasn’t looking! Don’t rush me.”

I poured more cola into the cup, feeling slightly relieved. 35%… Was that high or low?

“Yuuya, let’s watch a baseball game together. Eating pizza while watching sports is wonderful.”

“O… okay…”

Big Sis ate pizza while watching TV. I only ate one slice. I had no appetite at all. But I forced myself to eat more so she wouldn’t suspect anything.

“Yuuya, look! My favorite rookie player is up! His batting average is .350!”

Why did the number .350 have to come up right now?! I suddenly heard the TV broadcast.

『To the right field~~!! This is a big one! This is huge! Is it going in?! Is it in?! Is it in?! Is it in?!』

It’s not going in! Damn it!

『It’s in!!!!!!!! Commentator Johnson, what do you think of this at-bat?』

『No complaints here.』

……………

“Yay!! Yuuya, look! It’s a home run! My favorite player hit it!”

(The Boss ignores the woman’s feelings completely to update his record and thrusts her violently with all his strength. With that huge body and muscles, no woman can endure it. Many women have been broken after being raped by the Boss.)

I remembered what Alex said about the “home run.” If Big Sis gets broken… I looked at her happily dancing beside me. Instead of looking at her bouncing breasts, I stared at the area below her belly. That pill was currently being digested in her stomach… and would soon affect her womb…

『To the left field~~!! This one’s big too! This one’s huge! Is it in again?! Is it in?! Is it in?! It’s in again!』

……I wasn’t in the mood to watch baseball anymore.

“Big Sis, I’m going to sleep first. I’m really tired today.”

“Oh, so early. Go to the bedroom first then. I’ll keep watching the game.”

“Okay.”

Since I hadn’t organized my room at all, I ended up sleeping in Big Sis’s bed again tonight. I entered her bedroom and collapsed onto the bed. Even with my eyes closed, sleep wouldn’t come. The fear for my life, the guilt of making Big Sis take the drug, and the anxiety of having to make her take the second pill… My heart felt crushed under a heavy stone, yet I could clearly feel my heartbeat. I could hear my own heart pounding.

At that moment, Big Sis entered the bedroom. After changing, she got into bed and hugged me.

“Yuuya, are you asleep?”

“Not yet… Weren’t you watching the baseball game?”

“It’s mostly decided already. So I came to sleep with you.”

As usual, Big Sis hugged me like a body pillow.

“Yuuya, if something hard happens, tell me okay? Your master is strong. The environmental changes these past few days have been too drastic. There’s no need to rush. Take your time and get used to it slowly.”

I no longer had time. The changes were certainly drastic. From hellish slum life to what felt like heaven, and now falling back into hell. I might fall into real hell in a few days… the hell of losing my life…

“…Yeah. Got it.”

Today, I mostly just answered “got it” because I didn’t know what else to say.

“Wait, did something painful happen? Tell your Big Sis.”

“…No, nothing.”

I wanted to tell her.

“I’m still not used to this place yet.”

I wanted to tell Big Sis everything!

But even if I told her, what could she do? Could a witch who could only use petty magic win against 20 or 30 slum thugs? She herself had said many times that her magic wasn’t anything impressive… If she had fire magic, she could burn down the entire abandoned building… Thinking about things she couldn’t do was useless.

“I see. Then take your time getting used to it. Slowly, okay? Big Sis will always be with you.”

I could feel her warmth and kindness from my back, but the moment I made her take the pill, all of it lost its meaning. I became even more aware that I had betrayed her.

“I’m going to sleep now.”

“Good night, my beloved first disciple.”

The next morning, I had barely slept. My throat was dry, so I slipped out of Big Sis’s embrace, got off the bed, and went to get some water. After drinking, I tried to take a shower to clear my head, but it didn’t help much. When I came out of the changing room, Big Sis was already awake.

“Good morning, Yuuya. Did you sleep well last night? Whoa, you have terrible dark circles. Was my sleeping posture that bad?”

“…I’m fine. I’m still not used to the new environment.”

“Hahaha, I see. I got a little worried. My colleagues used to complain that I have bad sleeping habits. Oh right, I have to go out early today. I’ll probably come back late at night. You don’t have to wait up for me — go to sleep first.”

Big Sis won’t be in the office all day today!? Then I barely have any chance to give her the second pill!

“There’s still a lot of pizza left from yesterday. Is pizza for breakfast okay? It might be a bit heavy though.”

“It’s fine! Totally fine! I didn’t eat much yesterday, so I suddenly feel like eating it. You drink cola, right Big Sis? I’ll pour it.”

I told a terrible lie. There was no more time. I had to use her trust. After this, there would be no turning back.

“Then I’ll heat up the pizza. How many slices do you want?”

“Two is fine.”

I poured the leftover cola from the fridge into a cup. Then I dropped the pink pill into it. This time, with full intention. There was truly no going back now.

“Pizza’s heated. Let’s eat together.”

“Yeah!”

Big Sis drank the cola in one go without hesitation, just like yesterday. She didn’t notice the pill. I ate pizza pretending nothing was wrong.

“Fuu~ That hit the spot. Pizza really needs cola.”

“I’ll wash the dishes.”

“Thanks. I’ll go change.”

I checked the cup again. Nothing inside. After washing the dishes, about ten minutes later, Big Sis appeared in her usual work suit.

“Big Sis, the security around here isn’t great. Is it okay for you to always go out alone?”

I asked to confirm whether Alex and the others were tailing her.

“It’s fine, it’s fine. Big Sis has this.”

She pulled out a revolver from inside her jacket.

“My beloved gun — the all-black Colt Python .357. It makes any bad guy submit. Wahaha.”

“Is it real?”

An idea suddenly came to mind.

“Of course it’s real. Ah, don’t touch it, Yuuya. It’s still too early for you. The recoil on this revolver is very strong. But I have enhancement magic, so don’t worry.”

I started forming a plan.

“Today you absolutely have to organize your room, okay? At least move half the boxes to the fourth floor. I have to go now, so I’m counting on you to watch the house. See you later~”

Big Sis left the house. I began organizing my room. While carrying boxes, I thought about the plan. With that revolver, maybe I could do something. The success rate was very low, but not zero. I would bet on that small chance. The plan was simple: assassinate the Boss. Saeko’s revolver was my last hope.

At night, I pretended to sleep in bed first and waited for Big Sis to return. She came back quite late, but it didn’t matter.

“Yuuya~ I’m home~ Are you already asleep? Big Sis will take a shower. Let’s sleep together tonight too. Hehehe.”

After showering, Big Sis returned to the bedroom. Just a little longer — once she fell asleep, I would carry out the plan.

“Fuu~ That feels good. Tonight I’ll sleep while hugging my beloved disciple again. Ah, this feels a bit naughty.”

As usual, Big Sis hugged me tightly.

“Good night, my beloved first disciple.”

Just like last night, she always said this at the end of every day. Five minutes later, I confirmed she was asleep. But I wanted to feel this kindness just a little longer. Her body heat, her breathing, her sleeping face. This moment was mine. Since it was the last time, I could indulge a little, right?

! Dangerous. If I kept sinking into her kindness, I might really fall asleep. I slipped away from Big Sis and got off the bed. Before leaving the bedroom, I searched the room. No gun. Then I started searching the entire second floor.

First, the living room. Nothing. I suddenly remembered Big Sis happily dancing while watching the baseball game yesterday and smiled unconsciously.

Next, the changing room. Just in case, I checked the laundry basket. I remembered what happened here… when I saw Big Sis’s clothes and underwear… and the punishment…

“Punishment… haha. My first consecutive ejaculation, and it was by a beautiful big sister’s hand.”

I had searched almost the entire second floor. No revolver.

“Only the first floor left.”

I went down to the first floor and opened the office door. This was the first place I entered when I came to this house. When I ate the bread.

(Watching someone eat food deliciously makes them look so happy. And it makes the food taste better too. Hehe.)

I remembered what Big Sis said. Come to think of it, I don’t think I’ve ever properly watched her eat. A little regretful… but I probably won’t have another chance. No time to get sentimental. I started searching the first floor.

“Found it.”

It was in an unexpectedly easy place. The revolver was inside the drawer of Big Sis’s work desk.

“Alright. With this…”

I wanted to leave a final message for Big Sis. There was still time. That’s right — I’d write it on the laptop. I went back to the living room on the second floor, turned on the laptop, and remembered the observation report.

(Big Sis, my homework was only “observation,” right…?)

(No excuses!! Punishment again today!!)

“Haha, that was really funny. I wonder what happened to Johnny after that.”

After finishing the message, dawn was approaching. I took off the clothes Big Sis bought for me and put on my original worn-out clothes and shoes.

(Our image color is black! This is… that’s right! It’s the company image.)

“Ah, that department store talk. She chose everything in black… Why does saying goodbye to this black company feel so sad…”

Those few days felt like a dream to me.

“It’s about time. I really won’t be coming back here.”

I hid the black revolver behind my waistband and secured it with duct tape just in case. Then I left the black building.

“Goodbye, this ‘black dream’.”

The moment I left the black building, two or three people started tailing me. As a slum kid, escaping from tailing was easy. I was fast. Plus…

“My favorite tactic — using traffic lights. Well, I did get caught by Big Sis though.”

Even after leaving the office, I kept thinking about her. Haha… It was a short time, but it really made me…

“…Very happy.”

After that, I ran around the city all day to shake off the pursuers. Then, my final destination was…

“I’m here. The slums.”

At 21:30, I arrived at the abandoned building where the Boss was, earlier than planned.

“It’s Yuuya. The Boss said to come at 22:00.”

After the gatekeeper confirmed, I was allowed inside. I climbed to the first, second, third floor… It felt like climbing the scaffold to my execution. When I reached the fifth floor and headed to the Boss’s room, the gatekeepers let me through directly. Good. I had the chance to get close to the Boss. All that was left was to find the right moment to—

“Kill him.”

The moment I entered the room, what I saw was…

“Hey, set up the equipment properly. The lighting is insufficient!”

The Boss was giving orders to his subordinates.

“I told you to prepare a dozen batteries for the camera. Tonight is going to be a long battle.”

The Boss was wearing only a bath towel around his waist. He was fully motivated.

“I told you many times to put the lights here! This angle looks the coolest. Hmm? Isn’t that Yuuya?”

The Boss noticed me.

“Where’s that black woman?”

“She’ll be here soon. She has to do her makeup and stuff. She’ll arrive exactly at 22:00.”

“Did you make her take the medicine twice?”

“I did. It was really hard.”

It wasn’t a lie. I definitely made her take them.

“Boss, what is all this?”

To lower his guard, I started a conversation.

“Ah, this is to record the moment I achieve my record. Like filming an AV.”

The place was fully set up for shooting.

“I even thought of a title. ‘Stan-sama’s Breeding Show VOL.10 – The Moment the Black Witch Detective Becomes a Pregnant Witch Detective.’ My naming sense is great, right?”

“Amazing! Really!”

It was so disgusting I wanted to vomit.

“This is a series, you know. VOL.1 to VOL.9.”

“Wow. What was the previous one about?”

“Yuuya, you’re quite the pervert too. Hey, bring the VOL.9 sample.”

The chance came. While he was proudly introducing his disgusting AV, I’d shoot him in the head. It would all end!

“Look, this VOL.9 is my masterpiece. The title is…”

The moment I reached for the revolver hidden behind my waist, two subordinates approached from behind, grabbed both my arms, and restrained me.

“Boss! This guy betrayed us!”

“Shit! Let go!!”

Damn it! The ones tailing me came back so fast! I was so close!

“…Betrayed? What do you mean, Yuuya?”

The Boss’s voice dropped. He was angry.

“Hehehe… It means the black big sister isn’t coming.”

Thud

I suddenly took a punch to the gut.

“Guh!”

The air was knocked out of me…

“Bring Lucy!!!!!!!!!!!!”

The Boss completely lost it. He was shaking while holding the metal bat.

“Yuuya, I told you, right?! Lucy is very impulsive! Look at this shaking! I can’t hold Lucy back anymore!”

Keep telling yourself that. Don’t blame the bat.

“Because of you, the efforts of many people for this very moment have been wasted! The cameraman, the people who prepared the equipment — everyone was waiting for this moment!”

They’re almost all your subordinates… You’re the only one who was waiting.

“I even prepared an 8K video camera for today. And lots of memory cards. Do you know how many?”

“One, maybe? Aren’t you a premature ejaculator… Guh!”

Thud

Another punch to the gut…

“Today!”

Thud

“Twenty!”

Thud

“Cards!”

Thud

“I prepared!!!!”

Thud

After six consecutive gut punches, I coughed up blood.

“Damn it!! Everyone listen! Pack up the equipment! Load it into the cars! We’re filming at the black building!”

It was pointless. If Big Sis had read the message I left, she would have escaped long ago.

“Before going to the black building, I need to vent Lucy’s anger. On Yuuya’s head.”

Just as the Boss gathered strength to swing the bat at my head—

“Boss! Message from the gatekeepers downstairs! The black goddess — the black woman has arrived!”

A gatekeeper on the fifth floor reported. The black woman?!

“What?! Give me the walkie-talkie.”

What’s going on? No way…!

“Hey downstairs, it’s really the black woman, right?”

『No mistake, Boss. We used the photo you distributed many times. There’s no way we’d mix her up.』

“Fufu… Good. Everyone, prepare the equipment quickly! Hey, make that woman wait 15 minutes downstairs.”

『Understood.』

Damn it, what is this? No way…!

“Yuuya, sorry. I misunderstood you. But… you betrayed me once. So… Hey, bring a chair over here.”

I was weakly forced into a chair.

“Use that.”

What’s “that”…? Damn it, my body still won’t move.

“Tie both hands and feet tightly.”

Shit! My hands and feet…

“I saw this scene in an old AV. I always wanted to try it. Zip ties are really convenient.”

“Damn it! Let me go!”

I was firmly fixed to the chair with zip ties.

“You get the special seat. This is your reward for bringing the black woman here.”

I don’t want that kind of reward!

“Listen everyone, don’t enter this room. We’re filming. No one makes a sound without my permission.”

The people who prepared the equipment gathered in one spot.

“Oh right, our audience here needs to stay quiet too. Alex, tape his mouth shut. And I’ll give Lucy to you. If Yuuya makes any strange movements, follow my orders. Got it?”

“Understood. Sorry, Yuuya.”

Alex taped my mouth shut.

“Mmmmmm!!!!!”

Damn it, I can’t speak!

“Preparations are almost done. Hey downstairs, let the black woman up to the fifth floor.”

The Boss gave instructions via walkie-talkie.

『Understood. Fifth floor.』

“OK. Then… Action!”

After the Boss called “Action,” no one except him made a sound.

“Finally… It’s finally here! The moment Stan-sama achieves the record of impregnating ten women in a row!”

At that moment, a sound was heard.
