I opened the small bag and took out a pill.

  "35%... probability..."

  35%, about one third, one out of three times. It's okay, getting pregnant isn't that easy... Wait!! If big sister doesn't get pregnant... my life will be ruined!!... damn it!

  The hand holding the pill is already getting close to a gss full of co. This small pink pill has the same value as my life. I'm holding my life right now.

  "My hand... is shaking... what if I accidentally drop the pill into the gss..."

  This isn't on purpose. I just want to lessen the guilt a little bit. Because... it's a matter of life or death! It can't be helped!

  My hand is already moving towards the gss. Putting this pill into the co, and dropping it from my thumb and forefinger... it's a simple thing.

  "My hand won't stop shaking..."

  "I want to eat pizza~ pizza~ let's eat pizza~"

  Big sister is already here! I need to hurry! Huh? Where's the pill on my hand...? Did it fall into the co?

  "I'm thirsty, I'll drink first." Big sister lifted the gss and drank all the co in one go.

  *gulp* *gulp* *gulp*

  The Adam's apple is moving. She's definitely drinking the co. And the pill...

  *gulp* *gulp* *gulp* Aah~ co after work. It's irresistible. Yuuya, give me another one.

  "O-okay."

  I took the gss from my sister's hand and looked inside. There's nothing... she really drank it.

  "Why are you looking at the gss? Haha, you're imagining something naughty with the gss I used, aren't you~? You naughty boy, Yuya. It'll be troublesome if you grow up to be such a pervert. Hurry up and pour the co."

  "I-I'm not looking! Don't rush me."

  I poured the co into the gss again and felt a little relieved. 35%... is it high or low?

  "Yuya, let's watch a baseball game together. Watching a sports game while eating pizza is a wonderful thing."

  "O-o-okay..."

  My sister eats pizza while watching TV. I've only had one slice. I really don't feel like eating. But, in order not to arouse suspicion from my sister, I have to eat more pizza.

  "Look at that, Yuya! My favorite rookie pyer is on! His batting average is .350!"

  Why does the number .350 come up at a time like this! Suddenly, I listened to the TV broadcast.

  "To right field~~!! This is big! This is big! Did it go in? Did it go in? Did it go in? Did it go in? Did it go in?"

  It didn't go in! Fuck!

  "It's in!! Commentator Mr. Johnson, what do you think about this turn at bat?"

  "There's no doubt about it."

  ...

  "All right!! Yuya, look, it's a home run! My favorite pyer hit it!"

  (The boss, in order to set a new record, always forcefully pushes women aside, completely ignoring their feelings, with that huge body and muscles. No woman can resist. There are many broken women after being raped by the boss.)

  I remembered what Alex said about the home run. If my sister were broken... Instead of looking at my sister's jiggling breasts as she dances and ughs next to me, I look at the lower part of her abdomen. Those pills are being digested in her stomach right now. And they will affect her uterus...

  "To left field~~!! This is also big! This is also big! Did it go in again? Did it go in? Did it go in again?"

  ... I'm not in the mood to watch baseball anymore. I don't feel like it.

  "Sis, I'm going to bed first, I'm tired today."

  "Oh, you're going to bed early. Okay, go to your room first. I'll keep watching the game."

  "Got it."

  I haven't tidied my room at all, so once again, I'm sleeping in big sister's bed. After entering big sister's bedroom, I colpsed onto the bed. Even with my eyes closed, sleepiness doesn't come. The sense of danger to life, the guilt of making big sister take medicine, and the impatience of needing to make my sister take another pill... it feels like my heart is being pushed down by a huge rock. Despite being suppressed, I can strongly feel my heartbeat. Now I can clearly hear my own heartbeat.

  At that moment, my sister entered the bedroom. After changing her clothes, she got into bed and hugged me.

  "Yuya, are you asleep?"

  "Not yet... wasn't big sister watching a baseball game?"

  "It's almost over. That's why I'm here, to sleep with Yuya."

  As usual, big sister hugged me like a pillow.

  "Yuya, if something is bothering you, tell me. Big sis is strong. Maybe the recent drastic changes in environment have been too much. There are unfamiliar things and there's no need to rush. Take your time to get used to it."

  I don't have time left. The environment changes are indeed drastic. It feels like coming from a slum hell to heaven, and then falling back to hell. Maybe in a few days, I might fall into the real hell of losing my life...

  "Okay."

  I understood big sister's response today, but I don't know what to say, so I just replied with 'okay.'

  "Is there anything bothering you? Tell big sis."

  "No, nothing."

  I want to say.

  "I'm just not quite used to it here."

  I want to tell my sister!

  But even if I tell my sister, what can she do? Can a witch who can only use clever magic defeat 20 or 30 people in the slums? Sister has said it many times. Magic is not that big of a deal... If there was fire magic, you could burn down the abandoned building itself... It's useless to think about what can't be done.

  "Well then, just take your time to get used to it. Slowly. Sister has always been with Yuga."

  Although I felt my sister's warmth and kindness from her back, everything lost its meaning when I gave her the pill. I became even more aware that I had betrayed my sister.

  "I'm going to bed now."

  "Goodnight, my beloved number one disciple."

  .

  The next morning, I had hardly slept at all. My throat was dry, so I escaped from big sister's embrace, got out of bed, left the bedroom, and went to get some water. After drinking water, I took a shower to try and refresh myself, but it wasn't very effective. When I came out of the dressing room, big sister was also awake.

  "Yuya, good morning. Did you sleep well st night? Wow, those dark circles under your eyes are bad. Could it be because of my bad sleeping habits?"

  "Mmm, I'm fine. I'm still not used to the change in environment."

  "Haha, I see. I was a little worried. I used to be told by my cssmates that I slept badly. By the way, I'm going out early today. I probably won't be back until te at night. You don't have to wait for me, so go to bed first."

  Big sister won't be at the office all day today?! That means I won't have many chances left to give her the pill!

  "We still have a lot of pizza from yesterday, right? How about having pizza for breakfast? It might be a bit heavy."

  "Sure! Sure thing! I didn't eat much yesterday, so I suddenly felt like eating. You drink co, right sis, I'll bring some."

  I told a terrible lie. There's no more time. I'm taking advantage of my sister's trust. There's no turning back now.

  "Okay, I'll heat up the pizza. How many slices do you want, Yuya?"

  "Two slices will be fine."

  I poured the co left over from yesterday in the fridge into a gss. And then I put a pink pill into the co. This time, it's my own will. There's no turning back now.

  "I've warmed up the pizza, let's eat together."

  "Mm!"

  My sister drank the co without hesitation, just like yesterday. She didn't notice the presence of the pill. I ate the pizza as if nothing had happened.

  "Phew, that hit the spot. Pizza really does go well with co."

  "I'll go wash the dishes."

  "Please do, I'll go change."

  I checked inside the cup once more. There was nothing inside. And about ten minutes after washing the dishes, my sister came in her usual formal attire.

  "Sis, the security around here isn't that great, huh. You always go out alone, are you okay?"

  I asked my sister to confirm that Alex and the others were following her.

  "I'm fine, I'm fine. I have this," my sister said as she pulled out a revolver from her pocket.

  "My beloved gun, the jet-bck Colt Python .357, it will make any bad guys surrender, haha."

  "Is it real?" a thought came to mind.

  "Of course it is real. Oh, don't touch it, Yuya is still too young. This revolver has a strong recoil. But don't worry, I have strengthening magic," big sister assured.

  I pondered on a pn.

  "Today we must definitely tidy up the room. At least half of the boxes need to go up to the fourth floor. Sister is running out of time, so I'm counting on you to watch the house. See ya."

  With that, big sister left the house. I started tidying up my room. As I carried the cardboard boxes, I thought about the pn. As long as I had that revolver, maybe things would work out somehow. The chance of success is very low, but not zero. I'll bet on that slim chance. The pn is simple, assassinate the boss. My sister's revolver is my st hope.

  .

  At night, I pretended to be asleep in bed, waiting for my big sister to come back. Big sister came home quite te, but it doesn't matter.

  "Yuya, I'm home! Are you already asleep? I'm going to take a shower, let's sleep together tonight, hehehe."

  My sister took a shower and came back to the bedroom. As soon as she fell asleep, I would come up with a pn.

  "Ah, that feels good. Tonight, I'll sleep hugging my beloved disciple again. Oh, it's a bit naughty."

  My sister, as usual, hugged me tightly.

  "Good night, my beloved disciple number one."

  Just like st night, big sister always said this before going to sleep. Five minutes ter, I confirmed that big sister was asleep. But I wanted to savor this kindness a little longer. Her body temperature, breath, sleeping face. At this moment, she belonged to me. It's the st chance, so it's okay to indulge a little, right?

  Wait, dangerous. If I sink too much into big sister's kindness, I might really fall asleep like this. I moved away from my sister and got out of bed. First, before leaving the bedroom, I searched the room. No sign of a gun. Next, I began to search the entire second floor.

  First, the living room. I looked around but didn't find anything like a gun. Suddenly, I remembered big sister dancing and having fun while watching a baseball game yesterday, and I chuckled.

  Next was the dressing room. Just to be sure, I had to check the basket in the dressing room. I remembered what happened here. Seeing big sister's clothes and underwear in the basket. That, and...

  "This is punishment... Haha, my first experience of consecutive ejacutions, and with my beautiful sister's hand."

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

  "Only the first floor left."

  I went downstairs and opened the door to the office. This is where I entered this house for the first time, right? When I ate bread.

  Watching someone eat delicious food makes them look very happy. And the food tastes even better. Hehe.

  I remembered what my big sister said. Come to think of it, I haven't seen her eat yet. It's a bit disappointing, but maybe I won't have another chance. It's not time to dwell on memories. I started searching on the first floor.

  "I found it."

  Surprisingly, it was easy to find. The revolver was in a drawer of my sister's work desk.

  "All right, with this..."

  I want to leave a message for big sister. There's still plenty of time. I'll write it on the ptop. I returned to the second floor living room, started up the ptop, and remembered about the observation report.

  (Huh, big sister, my homework is supposed to be just observation, right...?)

  (No excuses!! It's punishment again today!!)

  "Haha, that was really interesting. I wonder what Johnny has been up to since then."

  .

  After finishing the message, dawn was approaching. I took off the clothes my sister had bought for me and put on my own first outfit and shoes.

  (Our image color is bck! This is...I know! It's the company's image)

  "Oh, the department store story. Choosing all bck for me, it's so sad to part ways with this bck company..."

  For me, the events of the past few days felt truly like a dream.

  "It's about time. There's really no turning back here."

  I tucked the bck revolver behind my pants and, just in case, taped it up. Then I left the bck building behind.

  "Goodbye, this 'bck dream'."

  .

  When I stepped out of the bck building, a few people immediately started following me. Since I'm a kid from the slums, it's really easy to shake off a tail. I'm fast on my feet. Plus...

  "My best strategy is using the traffic lights. Well, I got caught by sis though."

  I never would've thought about her even after leaving the office. Haha... A short time, but really...

  "I'm so happy."

  From then on, I kept running around the city to avoid being tracked. I ran almost all day. And finally, the destination was...

  "I made it, the slums."

  At 9:30 PM, I arrived at the abandoned building where the boss was supposed to be earlier than pnned.

  "It's Yuya. Boss said he'd come here at 10 o'clock."

  After the guard confirmed, I was led into the abandoned building. Climbing up the first, second, and third floors. It felt like climbing the gallows. When I arrived at the fifth floor, I went to the room where the boss was. The guard looked at me and let me go directly into the room. All right, now I have a chance to make contact with the boss. All that's left is to find an opportunity to...

  "Kill the boss."

  As soon as I entered the room, the scene that caught my eye was...

  "Hey, there, get the equipment ready. The lighting is insufficient, isn't it?"

  The boss was giving instructions to his subordinates.

  "I've prepared a dozen batteries for the cameras. It's going to be a long night."

  The boss had only a towel wrapped around his lower body. He was really full of motivation.

  "How many times do I have to tell you to put the lighting here! This angle is the best for me. Hm? Isn't that Yuya?"

  The boss noticed my presence.

  "What about the bck girl?"

  "She'll be here soon. She's doing her makeup and stuff. She'll be here at exactly 10 o'clock."

  "Did you make her drink the usual twice?"

  "I made her drink it. It was really tough."

  I wasn't lying. I definitely made sis drink it.

  "Boss, what the hell is this?"

  In order to lower my guard, I decided to talk to the boss.

  "Oh, this is to record the moment when I achieve a record. Like filming an AV."

  It felt like this pce was set up for recording something.

  "I even came up with a name. 'Stan's Breeding Show VOL.10 Moment when the Female Detective Becomes a Pregnant Female Detective'. My naming skills are top-notch, right?"

  "Amazing! Truly."

  It made me sick to my stomach.

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

  "Incredible. What was the previous one like?"

  "You're a pervert too, Yuya. Hey, bring out a sample of VOL.9."

  The moment had arrived. When you were introducing that disgusting AV, BAM! Right in the head. It will all be over!

  "Look, VOL.9 is my masterpiece. The name is..."

  Just as I was about to reach for the revolver hidden in my pants, two henchmen approached from behind, grabbed me by the sides, and restrained me.

  "Boss! This guy, he's betrayed us!"

  "Damn it! Let go!!"

  Damn it! The one tailing us, why did they have to come back so soon! Just a little longer!

  "...Betrayed? What's going on, Yuya?"

  The boss's voice lowered. I felt his anger.

  "Hehehe... Looks like the dark dy isn't coming."

  Thud.

  Suddenly, I got punched in the stomach.

  "Ugh!"

  The air in my stomach...

  "Bring me Lucy!!!!!!!!!"

  The boss completely lost it. He was shaking all over, holding a metal bat.

  "Yuya, I told you! Lucy is... very impulsive! Look at this trembling! I can't stop Lucy anymore!"

  Don't bme it on the metal bat.

  "For this moment today, the efforts of many people have been wasted because of you! The cameraman, the people who prepared the equipment. Everyone was waiting for this moment!"

  You're practically his henchman... You're the only one waiting.

  "I even prepared an 8K video camera for today. And plenty of memory cards. How many did you prepare?"

  "Probably just one, you're too quick... Argh!"

  Thud

  I took another gut punch...

  "Today!"

  Thud

  "There are!"

  Thud

  "20!"

  Thud

  "Memory cards!"

  Thud

  "Prepared!!"

  Thud

  After taking six consecutive gut punches, I vomited blood.

  "Damn it!! Everyone listen! Gather the equipment! Load it into the car! We're shooting at the Bck Building!"

  It's pointless. If sis has read the message I left, she's probably long gone.

  "Before we go to the Bck Building, we need to calm Lucy's anger. Yuya, figure it out."

  Just before the boss could swing the bat at my head after gathering his strength,

  "Boss! The guard at the bottom called! The Bck Goddess, the Bck Woman has arrived!"

  The guard on the 5th floor reyed a message to the boss? The Bck Woman!?

  "What! Pass me the transceiver."

  What's going on? No way...!

  "Hey, at the bottom, it really is the Bck Woman."

  "No mistake, I've used the photos given by the boss multiple times. There's no way I'd mistake her."

  "Hehe... Alright, everyone, hurry up and get the equipment ready! Hey, make her wait for 15 minutes."

  "Understood."

  Shit, what the hell is going on. No way, really!

  "Yuya, I'm sorry. I misunderstood you. But you know, you betrayed me once... Yeah. Hey, bring that chair over here."

  I was weakly forced to sit in the chair.

  "Use that."

  What the hell is that...? Damn, I still can't move my body.

  "Tie up both hands and feet properly."

  Damn! My hands and feet...

  "I saw this in an adult video once. I've always wanted to try it. Cable ties are really handy."

  "Shit! Let me go!"

  I was fixed to the chair with cable ties.

  "It's a great seat, right? It's a reward for bringing the bck woman here."

  I don't need that kind of thing!

  "Listen, everyone, don't come in here. We're filming. Don't make a sound without my permission."

  The crew preparing the equipment gathered in one pce.

  "Oops, the audience here needs to be quiet too. Alex, tape his mouth shut. And give Lucy to you. Yuya, if there's any weird movement, follow my instructions. Got it!"

  "Got it. Sorry, Yuya."

  Alex taped my mouth shut.

  "Mmmmmmm!"

  Damn, I can't make a sound!

  "Looks like it's almost time. Hey, let the bck woman downstairs through, to the fifth floor."

  The boss gave instructions to the gatekeeper downstairs via a walkie-talkie.

  "Understood. Fifth floor."

  "OK, let's start shooting! Action!"

  .

  After the boss made the call for action, not a single person other than the boss made a sound.

  "Finally, finally! The time has come for Stan-sama to set the record for impregnating ten women in a row!"

  At that moment, a sound could be heard.

  Knock, knock, knock.

  What is that sound? I've heard it before...the sound of high heels! Could it really be?!

  Knock, knock, knock.

  "That sound is truly unbearable...the elegant sound of a beautiful woman walking in heels..."

  Knock, knock, knock.

  The sound of high heels grew louder and louder.

  "Come, come, come."

  Don't come! Don't come! Don't come!

  Knock, knock, knock.

  She's already on the fifth floor! Is she really your sister?! Hurry up and run!

  Knock, knock, knock.

  And then, a woman in a bck suit appeared in front of me.

  Why?! Why are you here?! Big Sister!

  "I've come to retrieve my disciple."
