Lewd Encounter with Yoon Bom in the Bathroom (1)
I returned to the house after tidying up the Comic Book Cafe. I called it "home," but it wasn't really mine. Strictly speaking, it was Kwon Hyejung's house. She had told me, "From now on, think of this as your home and let's live well together." But every time I opened the front door and stepped inside, an uncomfortable feeling crept up in the corner of my heart. The question "Am I really allowed to live here?" still lingered, and I felt like an alien presence. It was like forcing mismatched puzzle pieces together.
That was probably why I had never tried talking to Yoon Bom or Yoon Gaeul. I had planned to move out and live on my own anyway. Since I never intended to stay here long-term, I saw no point in trying to get close to them.
"I'm home," I muttered quietly, but there was no reply. The house was dark and silent. Kwon Hyejung seemed to be asleep already, and Yoon Bom and Yoon Gaeul were probably each doing their own thing in their rooms.
"I should take a shower first… and try out a few things."
I went into my room, stripped off my clothes, and placed the Lewd Notebook on the desk. This notebook was the real deal. If I wrote down a lewd scenario following the 5W1H principle, it would actually manifest in reality. That much was certain after seeing all those adult women who visited the Comic Book Cafe before the deadline suddenly start begging me to suck on their exposed nipples.
"I don't know why this is happening to me… but it would be a waste not to use a treasure like this. With this power, I can do whatever I want with Yoon Bom, Yoon Gaeul, and countless other women."
Grabbing a change of underwear and a towel, I walked down the dark hallway and flung open the bathroom door. I was only wearing panties, but I didn't care. After all, I had never once run into Kwon Hyejung or the Yoon sisters at this hour. That was why I had let my guard down.
"……"
Something felt off—the bathroom light was on. It should have been dark. Not only that, the inside was humid and warm, probably because the bathtub was filled with hot water.
Whoa… those tits are huge.
That was my first impression upon seeing the breasts floating on the water. They were on par with Kwon Hyejung's… no, at a glance, they looked even bigger. The blue tint in her hair told me it was Yoon Bom—the older sister Kwon Hyejung had asked me to talk to. She was soaking in the tub, enjoying her bath.
"I thought you were the quiet type… but I guess not."
Yoon Bom opened her eyes and looked at me. She made no effort to cover her chest, lounging in the tub as if to say, "Look if you want." Water droplets clung to her skin.
"You're letting cold air in. Decide quickly—come in or get out."
"S-sorry."
I blurted out an apology and slammed the door shut, then hurried back to my room. Once there, thoughts started swirling in my head. Why was she bathing at this exact time? Did she not know I would be coming home around now? Even if she didn't, shouldn't she have locked the door while showering?
I considered opening the door again and going back in, but I calmed myself and decided to wait quietly. Her words had sounded like permission, but they didn't feel sincere.
Ten minutes. Twenty. Thirty. Past midnight, and Yoon Bom still hadn't come out of the bathroom. She was taking so long it seemed like she might have fallen asleep in the tub.
"This is ridiculous. She knows I'm waiting to shower, yet she's been in there for over thirty minutes?"
Annoyed, I opened the Lewd Notebook. Then I shuddered. Was I always this perverted? Getting irritated and immediately reaching for the notebook to play a lewd prank… Back in the military, going a month or two without sex had been normal. Could the Lewd Notebook be having some corrupting influence on me? Just like how people now casually accepted lewd acts as normal, had something changed in me without my realizing it?
"Well… if that's the case, there's nothing I can do about it. It's not like there's a way to resist, and I don't particularly want to resist anyway."
With a pounding heart full of anticipation, I placed my hand on my chest and reread the rules written on the first page of the Lewd Notebook.
Rule 1: It grants one lewd fantasy into reality per day.
So when exactly does the day reset? At midnight? Or when the sun rises?
Rule 3: A lewd act lasts up to 24 hours. That meant the effect could end sooner than 24 hours. Since it was a maximum of 24 hours, if I wrote a new lewd act before the previous one expired, the old effect would end and the new one would activate.
I picked up a pen from the desk. There was no point pondering alone. If I had questions, I should just ask. Ask who? The Lewd Notebook, of course.
Rule 8: Additional questions can be written in the Lewd Notebook to receive answers.
Let's try that. I wrote down a question.
In Rule 1, it says "one lewd fantasy per day." What exactly counts as a day?
A day refers to the period from 00:00 to 24:00. It resets at midnight. As you guessed, once 12 a.m. passes, you can create a new lewd act. When a new lewd act takes effect, the previous one loses its power.
"This is… kind of creepy. Don't tell me it's reading my thoughts too?"
The instant reply reminded me of those trendy AI chatbots, but the way it answered questions I hadn't even written yet sent a chill down my spine.
"Alright. That means I can use the notebook right now since it's past midnight. Let's try it."
I took out another notebook and carefully organized the content. I wanted to write it neatly in the Lewd Notebook.
"Okay. This should work."
I transcribed the organized text into the Lewd Notebook.
— Yoon Bom / from now on for 24 hours / anywhere / will think of her stepbrother Yoo Eunho as her boyfriend's replacement and demand lewd acts. With a submissive and open mindset / believing that having sex with Yoo Eunho is the best way to soothe the pain of her breakup. —
Did it work? Just as I wondered, the bathroom door burst open. Light and white steam spilled into the dark hallway, followed by a completely naked Yoon Bom.
Damn… her body is insane. Does she work out separately?
Just standing there, she looked like a photoshoot model. Long legs, firm honey thighs, a smooth hairless pussy, a slim waist, and above it all, impossibly large breasts. What cup size was that? I'd only ever seen A, B, and C cups my whole life, so I couldn't even guess. Was this the legendary G-cup goddess?
"Haa… so annoying."
Yoon Bom muttered under her breath and strode toward me, water dripping from her undried body. She made no attempt to cover her breasts or pussy. With a face mixing languor and irritation, she walked straight into my room.
"Oppa, want to shower with me?"
"……"
"I'm too stressed to relax. I'll wash you, so lend me your cock."
With a face that could easily be the center of an idol group, she said something unbelievably lewd. "Lend me your cock." I'd never heard anything like it before.
"Bom, we've barely even seen each other's faces."
"Huh? So what? What's the problem?"
Yoon Bom tilted her head, brushing back her wet hair.
"Asking to borrow my cock… that's basically asking to have sex, right?"
"Yeah. Where else would I use it except for sex?"
"We're family now. You're my little sister. You're still asking?"
"You've been saying weird things since earlier… Right now, you're my boyfriend's replacement. I'm annoyed because I just broke up, so fuck me already."
"……"
I looked down at the Lewd Notebook. I had a strong feeling my life was about to change completely because of it. This thing was a fucking treasure.
"You don't want to? It's a safe day, so you can cum inside."
"I-if you're going that far, I guess I have no choice. Kwon Hyejung asked me to get along with you anyway… Big brother will help you out in various ways."
"Thanks. I'm glad."
