After taking a shower, I dragged my feet towards the changing room. There is a bck t-shirt next to the basket. It's probably the clothes that my older sister prepared. She's still taking a shower.

  "My lower body strength... it's hard to walk..."

  My first experience with rapid ejacution made me more tired than I thought. It's as if my lower body isn't mine anymore.

  "Put on the t-shirt... huh?"

  When I put on the t-shirt, I noticed a logo written in white letters on top.

  "Bck... I don't really want to wear it."

  Just how much does this older sister like bck... all the way down to the t-shirt. And I have nothing to wear underneath. She probably lives alone, so there are no men's clothes or pants. Even though my lower body feels cool, I have to endure it because I'm in someone else's house.

  Back in the living room, the cat president is rexing on the sofa. A bck cat, I think its name is Yami. Bck + Yami + President = Bck President...

  TL' Note: ."黒い" (kuroi) means "bck.".

  "ヤミ" (yami) can mean "dark" or "darkness."

  ."社長" (shachou) means "president" or "company president."

  Putting these together, the sentence implies a pyful transformation of the terms into "ブラック社長" (burakku shachou), which can be interpreted as "Bck President" or "Dark President." This type of wordpy is common in Japanese and can create witty or memorable associations based on the meanings and sounds of the words used.

  "Did I accidentally join some kind of bck corporation?"

  I feel like I'm breaking out in a cold sweat...

  "Why is this cat grinning like that? Did it see me being chastised? Since we're both males, let's team up! Shouldn't we defeat the Bck Witch together?"

  I want to pick up the cat boss, but before I can get close, the boss quickly jumps to another pce.

  "...Listen, I don't have the energy to chase after you anymore, and after losing a strong ally, I won't form an alliance with you ter."

  I colpsed onto the sofa, exhausted.

  "This sofa feels nice... It's been a rough day."

  First, I failed at stealing bread, and then I was caught by a strange woman and taken in by her. She started calling me her disciple or a witch out of nowhere, but what does that even mean? But for now, having a pce to sleep and food is enough. I don't really want to live here for real.

  "Ahh, that's better."

  The woman emerged from the bath, wearing sheer bck lingerie and no bra, her nipples faintly visible. It was a very erotic sight. She also wore sheer thong panties, with a glimpse of her pubic hair visible... But I had just finished four times earlier, so it's sage mode now. That kind of sight doesn't work on me! Even after saying that, but I don't know where to look.

  "You must be feeling refreshed too, Yuya."

  The woman sat next to me. She had a pleasant female scent. My dick started to get a little excited again. I covered myself with both hands, just in case I get punished again.

  "What are you looking at? You little pervert, aren't you satisfied with what you already did before?"

  As she said this, she reached out her right hand. Her five fingers moving in a strange way in front of my eyes.

  "I-It's because of your actions! It's not my fault!"

  I diverted my gaze from the woman's body to somewhere else.

  "It's my freedom to wear whatever I want in my house. Well, I won't punish you anymore. Yuya is also a boy, so it's better for you to get used to the stimution of adult women rather than looking at me with those sneaky eyes. Sometimes people looks at me like that, but I don't really like it."

  "O-Okay. Then I will look directly."

  "Oh! Look as much as you want! My sexy body!"

  When I directed my gaze at my sister, what caught my eye was the part that was transparent above her panties. Her pubic hair.

  "Yuya is quite a maniac. You were looking at that part at first. Heh heh."

  "No! It's because my gaze was originally directed downward!"

  I said, facing big sister's face. The smiling sister who returned with a grin on her face seemed like a lie compared to the sharp-eyed sister who was in the bathroom earlier.

  "I've eaten, taken a shower, punished you. There are things I want to expin to Yuya, but...it's a bit of a hassle. Hmm...alright! Let's py a game."

  "Another game...?"

  "Oh no, it's not like that game we pyed earlier. Don't worry. It's the Witch's Q&A game!"

  The witch again. What in the world is that? I don't really understand things like witches and disciples.

  "The game is simple. Yuya, you ask me a question. I'm sure you have a lot of things you want to ask. I'll answer them. In this game, you can switch the right to ask questions, so when you want to ask a question, decre 'I have a question'. The one who decred first can ask a question. Why don't you try asking a question as a trial?"

  I've decided, my first question is...

  "What is a witch?"

  "Boo-boo, you didn't decre that you were about to ask a question. This makes the problem invalid."

  This is annoying...

  "I have a question. What is a witch?"

  "Just what the word means, a woman who can use magic."

  "I have a question. Can Yuya still be avaible? Heheh..."

  "T-That... I don't know."

  ...So this is the rule, suddenly being asked a question, I couldn't react.

  "Hahaha, this is how we switch the questioning rights. There's no order, first come first served. Alright, let's continue. Witch Q&A, start!"

  "I have a question. What kind of magic can you use?"

  "It depends on the witch's own aptitude. But even though it's called magic, it's not as grand as in a fantasy world with fire or wind magic. I can use some simple magic. For example, there's strengthening magic that enhances one's strength. Well, even with strengthening, it's only up to as strong as a powerful adult man. It's impossible to lift a car or anything like that."

  I see, so the reason she was able to hold me in one hand and restrain my body in the bathroom earlier was because she used magic.

  "I have a question. Can you use other magic as well?"

  "Yes, I can. There are so many types that I can't expin easily. Let's see... the entrance. The door unlocked, right? That was done using unlocking magic. It's the same when I lock the door."

  "I have a question. Is there magic that makes you fly in the sky?"

  "No, there isn't. Like I said earlier, witches' magic isn't that powerful."

  It seems like only petty magic... I'm a little disappointed.

  "I have a question. Can I use magic too?"

  "I don't know. You might be able to use it, or you might not. If you become my disciple, you might find out or you might not know."

  There are so many "mights"... What's the point of asking then?

  "I have a question. What is a disciple?"

  "It means exactly what it says, a witch's apprentice that can use magic. Since this is a detective agency, you'll also need to acquire detective skills. A witch detective's apprentice. Sounds good, right?"

  It does sound pretty good.

  "I have a question. What do detectives do?"

  "Oh! You asked a good question. Those who do not work shall not eat. You'll usually assist me in my work. Yuya can't drive yet, but in the future, part of your job will be my driver. Also, cleaning the office and the house. Taking care of the president, etc."

  It sounds like a housekeeper... but as long as I have food and a pce to sleep, it's not a big deal.

  "I have a question. Why are there so many bck things?"

  I've been wanting to ask this for a while!

  "It's because I'm a bck witch. I have an affinity for dark things."

  Does that mean you have an affinity for the color of your underwear too? Would you get diarrhea if you wore white underwear?! I'm tired... I have more questions, but I can't process them all at once.

  "I have a question. Is Yuya a virgin?"

  "What kind of question is that?! I-I don't want to answer."

  "Aww, come on. But, in the one question, one answer game, you have the right to refuse to answer. Just decre 'I refuse to answer the question.'"

  "I have a question. How many times a day does sis masturbate?"

  "I refuse to answer the question. Well done, Yuya. You quickly used your refusal right. Well, it's te at night, so let's go to bed soon. When ending the one question, one answer game, you need to make a simir decration. Both pyers have to say 'The witch's Q&A is complete, I approve.' Come on, let's make that decration quickly."

  Ugh, this game is troublesome...

  "The witch's Q&A is complete, I approve."

  "It's over, wasn't that fun?"

  "Not really... I don't understand the point."

  Well, you'll understand it eventually. Alright, I'll go get the contract for you to become my disciple. I think I left it in the office, so wait here."

  Sis went downstairs. I looked at the president again.

  "I forgot to ask about the bck company..."

  Accidentally becoming a witch's apprentice...
