Ch.184Special Chapter: Nipple Development Journal

# Enhanced Translation

“Hey. I can’t see. Move aside.”

“No.”

“……”

When I look at Cuss, I can’t help but think she’s just like a kitten.

She’s exactly the same in how she finds warm spots with uncanny precision and plants her butt there.

I guess since the leather sofa is a bit cool, she’s using my lap as a heated seat to sit on.

The first few times I pushed her away or gave her a poke in the butt to remove her, but she kept sticking to me, so I’ve half given up.

Every time her silver hair tickles my neck, I’ve been tempted to cut it all off more than once, but I decided to endure it.

In exchange, this position lets me touch her chest as much as I want.

“Mmph… Mmm… There. That hurts a little, Jinsoo.”

“Got it. Sorry.”

Maybe because she’s in her growth phase, sometimes I feel lumps, but as long as I avoid those areas, Cuss doesn’t really resist much.

It’s not because she understands the concept of equivalent exchange—I let her use my lap, and she lets me touch her chest.

She probably just decided that paying attention to the ticklish feeling on her chest while trying to focus on the television isn’t economical.

That’s the kind of girl Cuss is.

I decided to take advantage of this and write a development journal.

The following content may or may not be fictional.

You’re free to imagine whichever you prefer.

“Hyuk?! That hurts, Jinsoo!”

“Aaaah! You little shit! Why are you biting my wrist…!”

Development Day 1.

As a test, I tried repeatedly pressing hard on the lumps to stimulate them.

The resistance was stronger than expected.

She left significant teeth marks on my wrist, so I retaliated.

I left a dark hickey on her side, so now she won’t be able to show her stomach in public.

“Ah! Damn!”

Good heavens.

Am I an idiot?

Who’s the one who would be troubled if the hickey was discovered?

This bitch would happily run to the police and show them her side without hesitation.

I momentarily forgot that Cuss doesn’t possess the emotion of shame that normal humans have.

“Jinsoo. Is this how humans make requests?”

“I’m sorry… I’m sorry for biting your side, so please don’t show it to anyone…”

“Hmm. Well well, I’m so hungry I can barely hear you. I think I might hear better after eating a Big M set…”

Big Mac set?

No need to cook, so thank you, you idiot.

Fortunately, Cuss has cheap taste.

Still, I learned a lesson from this opportunity.

Never leave marks when biting or hitting her.

If marks do appear, it’s best to leave them on her butt, close to the tentacles.

If she tries to show the marks, she’d end up revealing her tentacles.

What a productive day.

“Is this a daily documentary?”

“Monday, Wednesday, Friday… Mmm… It’s a… ugh… regularly scheduled program… at this time.”

“I see.”

Development Day 2.

I changed my development approach a bit.

Since her breasts are small and uncomfortable to hold because of the lumps, I decided to focus on the nipples.

As a result, her reactions increased slightly.

Before, she would focus on the television and show little reaction.

At most, she would get annoyed when I accidentally touched a lump.

But when I started focusing on her nipples, she began showing more diverse reactions.

“Mmph… Nnngh…”

First, her moans started to mix with pleasure sounds.

And she couldn’t stay still, wiggling her butt.

Yet it wasn’t bothersome enough for her to resist by giving up watching her favorite program, as she never tried to remove my hand.

This was a good sign.

It always starts with feeling ticklish and annoying.

The development was showing green lights.

“Jinsoo. What’s the meaning of this thing you’ve been doing every day? It’s distracting me from watching TV.”

“There’s no special meaning. It’s just a normal growth check between father and daughter, so bear with it. All humans do this.”

“Is that so?”

“Yes. Just wait a few more days.”

“Mmm… But it’s a bit ticklish… ahh…”

Development Day 3.

Cuss started questioning the development.

She must have felt that this was somewhat different from my habitual actions like patting her head or smelling her nape.

She detected it accurately.

I was indeed purposely developing her, increasing the intensity little by little each day.

The development results so far are as follows:

She no longer shows any resistance when I grab her chest.

Compared to before, when she would flinch and tremble even while focusing on the television, this was a significant change.

Instead, all that sensitivity has concentrated on her nipples.

Previously, she would just purr as if ticklish when I poked them, but now her reactions had clearly surpassed the level of mere ticklishness.

She probably still describes it as ticklish because she can’t find the vocabulary to explain this sensation.

“Mmph… Mmm… Hyuk…”

Development Day 5.

Her nipples have become quite sensitive.

Now even a light touch makes her moan and breathe roughly.

Additionally, when I roll them between my fingers, she gradually starts panting and twisting her body.

Despite this, her gaze never shifted from the television.

Truly remarkable concentration.

“Hyuk?!”

“Oops. Did that hurt?”

“N-no… It was just a little ticklish…”

Development Day 7.

I started pinching her nipples.

At first, I began by gently pressing with my index finger and thumb, planning to gradually try twisting them harder.

Painful moans mixed with her pleasure sounds, suggesting some pain was involved, but now she seemed unable to distinguish whether it was pain, ticklishness, or some unknown sensation.

The haphazard training without a plan actually helped confuse her senses.

Is this what they call beginner’s luck?

I should apply this lesson in the next training session.

“What’s this? It’s not broadcast time yet.”

“Just felt like watching commercials. Give me your lap.”

“Uh…”

Development Day 9.

Cuss has become much more diligent.

She used to come running when the program started and jump onto my lap, but strangely, she now comes early and sits down in advance.

This was a sign that the training was working well, but this is exactly when I should hold back.

If I get excited by progress and try to rush things, I might ruin everything.

I should continue the development without major changes for at least three more days.

“Hmm…?”

“What is it, Jinsoo?”

“Isn’t your bra too tight?”

“It does seem so… I’m not sure.”

“Let’s go buy a new one.”

Development Day 12.

Cuss’s breasts have grown.

Her original double-A junior bra no longer fits.

I couldn’t tell if it was due to the development or just her natural growth phase.

“Try this on and come out.”

“I’ll help your daughter with her underwear. Please wait, father.”

“Alright.”

“Are you crying right now, father?”

“Huh? What?”

Only then did I realize.

I was stupidly shedding tears.

Cuss grows day by day.

Her breasts suddenly got bigger.

The Cuss who used to wear junior bras is now dead and gone.

That small girl now only lives in my memories and photographs.

Thinking about it made me feel suffocated.

This must be the sorrow that fathers feel and go through.

It’s painful, but I decided to endure it.

From now on, I’ll take lots of pictures of Cuss.

Whether she’s sleeping, eating, or pouting—everything.

So that I won’t regret it later when Cuss spoils, I decided to preserve plenty of images from when she was fresh.

“Hmm…”

“What’s wrong? Aren’t you going to touch today?”

“I will. I’m going to, but…”

Development Day 14.

As usual, Cuss sat on my lap 20 minutes before the documentary program started, and I noticed a strange change.

Her nipples were erect.

Well, the erection itself wasn’t that unusual.

Her sensitive nipples would quickly become stiff with just a light touch.

The issue was that they were already like this before I even touched them.

“Is there a problem?”

“No.”

As I leaned forward to peek, Cuss seemed to notice something was off and exhaled with displeasure.

Then she subtly rubbed her back against my chest and slowly pulled my hand.

Is this Pavlov’s dog effect?

Nipples that react before even being touched.

Can something this lewd exist in this world?

Witnessing the results of my own training made me shudder.

‘Today’s the day.’

The time had come to check the intermediate results of this long and intense training.

The key question was: can she climax from nipple stimulation alone?

That’s what I planned to confirm today.

“Mmmmph…”

From the start, I firmly grabbed and pulled, causing a yearning voice to escape her lips.

Since they were already stiff from the beginning, I didn’t need to bother with grabbing and twirling them, which was convenient.

After pulling them firmly, I stimulated them by lightly tapping.

The point is to tease by giving only light stimulation while making it seem like I might pinch hard.

“Mmm… Nnn… Mmph…”

“Oh. The documentary is starting.”

“I… know… Hyuk?!”

Then I suddenly pinched hard at an unexpected moment.

Cuss trembled all over and convulsed.

Not quite a climax…

It would be more accurate to say her body was startled.

“Jinsoooo… Uuu… I feel strange. I can’t… Hyuk?! Concentrate on the TV…”

“Stay still.”

Her concentration was starting to be affected.

Perhaps because I suddenly increased the intensity, Cuss couldn’t adapt at all, and her gaze was directed downward.

Seeing that the goal was in sight, I didn’t stop but moved my hands more actively.

Despite her intense twisting and trembling, her resistance wasn’t particularly fierce.

She would reach back to touch my neck or tap my thigh, but she made no attempt to push my hands away directly.

I could take this as implicit consent.

It seemed I didn’t need to worry about her going berserk and biting my hand if I went all the way.

“Oh. The reactions are coming now.”

“Stop… Mmph… Ugh… Stop it, Jinsoo…”

Her breathing became much faster.

It was similar to the sound of breathing after sprinting 100 meters at full speed.

As I continued to stimulate her areolas by circling around and occasionally pinching hard, new reactions began to appear.

Her legs, which had been spread wide like an old man’s, closed modestly; her previously calm toes started wiggling; and her shoulders gradually widened.

It seemed like she was about to climax grandly.

This would probably be the final moment.

I twisted and pulled both nipples.

“S-stooop…?! Ahk? Hyuk? Hak…! Hageuuk!”

“That’s right. That sensation right now is what we call ‘coming.’ Remember it well.”

Cuss’s waist arched back as she reached an intense climax.

Her curled toes rubbed against my leg while trembling, and her entire body remained rigid for about 3 seconds, unable to control itself properly.

“Hyuk… Hik… Mmph…”

Even after the climax passed, Cuss couldn’t regain her senses for quite some time.

To think she could achieve a nipple orgasm in just two weeks.

This was no ordinary talent.

After breathing heavily for a moment, Cuss raised her head to look up at me.

Then she painfully parted her lips and whispered something.

“Jinsoo… I… I wet myself…”

“Damn it.”

I immediately put my hands under Cuss’s armpits and lifted her up.

It was true.

No wonder my thighs felt warm.

Her entire pants were soaked, with warm steam rising from them.

Damn girl.

I need to scold her, so I’ll end today’s journal entry here.

Development Day 15.

Juliane’s visits have become quite frequent.

Today she stayed at home all day, so I couldn’t proceed with any development.

If I don’t take any action after progressing this far, there’s a risk that the sensitivity I’ve built up will reset.

Although it’s a bit risky, I’ll have to proceed while avoiding Juliane’s eyes.

As long as Juliane doesn’t discover this journal, I’ll continue writing it as pla-
