I Hate Myself for Getting Hard from Seeing My Daughter

The sound of rushing water filled the air.

As I approached the bathroom, the steady stream of water became audible.

Is she still showering?

I stepped closer, right up to the bathroom door, and heard the wet slap of slippers against tile—the same sound you’d catch in a military shower room.

Squelch. Squelch.

Interspersed with it came a soft, pleased hum.

It sounded just like the little tune A-yeong makes when she’s feeling good.

She must be enjoying her shower.

For nearly ten years now, the routine has been set in stone: I shower first, then A-yeong follows. Back when I was still a pudgy middle-aged man, I made sure to wake up early, exercise, and shower before her so she wouldn’t feel uncomfortable. That habit eventually became our natural order.

But… if she’s had the water running this long, the bill is going to be brutal.

Living alone as the sole provider for the two of us has made me frugal about little things. Normally I’d say something about wasting water.

I can’t exactly lecture her this time.

It’s her first day of university, after all. She might be taking extra time to get ready. She doesn’t usually shower this long.

She really does sound happy, though.

She only hums like that when I praise her.

Maybe getting into the university of her dreams feels that good. Just picturing her face made me smile.

Still… time’s running out.

The clock was already creeping toward eight.

Considering how long women take to do their makeup, we were out of time. I knocked on the bathroom door.

“A-yeong, you almost done?”

…

No answer. I knocked again.

“A-yeong?”

“What is it, Dad?”

The water shut off, and her voice finally came through the door.

“It’s almost eight. You still got a ways to go?”

“No! I-I’ll be right out! I just finished washing!”

She must have realized I was asking how much longer she’d be, because the distinctive wet slap of bathroom slippers hurried toward the door.

They stopped right on the other side. I could hear the rubber squeaking against the floor.

Did I sound too impatient?

The hurried footsteps made me feel a little guilty, so I backed away from the bathroom.

“Alright. I set breakfast out, so come eat when you’re ready!”

“Okay!”

I was planning to feed her by nine and drive her to school…

A-yeong was running later than expected.

She’s going to be late.

Well, nothing I can do about it. I’ll just take the scolding from my boss.

Most of the researchers have families. They’ll probably understand if I explain.

While I waited for A-yeong, her voice called out from the bathroom.

“Dad!”

“Yeah? What’s up?”

“Can you bring me a pad? I forgot to grab one!”

A pad?

She’s a grown woman and still can’t remember something like that? Doesn’t she feel embarrassed asking her dad?

Still, the fact that she trusts me that much secretly made me happy.

I did buy her some, but where does she keep them?

I always leave them out and she takes them to her room, but I’ve never seen where she stores them. I try to respect her privacy so I don’t go into her room unless necessary. That’s why I don’t know the exact spot.

“Where are they?”

“In my room, bottom right drawer of the closet!”

“Got it. Hang on.”

I stepped into her room and was immediately hit by that sweet, feminine scent unique to a girl’s space.

Why does it smell so different from mine?

We use the same diffuser, yet the scent changes completely. A-yeong always tells me my room smells nice too, but I know she’s just being nice.

My room always feels a little musty…

Her room was decorated with cute, charming details. I walked past the neatly coordinated blue-toned modern bed and desk and reached the closet.

Let’s see…

Bottom right drawer, right?

I slid it open with a rattle and found it packed full of neatly arranged pads in white packaging.

Here we go.

I grabbed one and closed the drawer, then reached to shut the closet door.

Huh? What’s that?

In the back corner of the closet, something caught my eye. A round shape with a stick attached.

A microphone? Does A-yeong sing?

Curious, I reached for it. I immediately regretted that decision.

“Th-this is…”

It had been too dark inside the closet to see the color clearly, but under the light it was obvious.

A round plastic body. A pink shaft and cord. And a switch.

A rotor… and a vibrator?

I stared ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠at the toys in my hand for a moment, then quickly put them back exactly where I found them.

Well… that’s normal. Lots of girls have at least one toy.

My daughter’s ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠masturbation aids. It was incredibly awkward, but…

Compared to the more extreme tools that existed in this world, the fact that she owned something relatively soft and gentle actually felt like a relief. Was that just me coping?

No, it wasn’t. I genuinely felt reassured.

A-yeong often shows me her defenseless side. I’d been worried she might lack proper sexual knowledge and considered giving her another sex-ed talk. Looks like I was overthinking it.

I shouldn’t be thinking about my daughter’s sex life. Forget it. Just forget.

But the human brain doesn’t understand the word “no.”

The more I tried to shake the image away, the clearer the vision became—A-yeong using those toys.

Because of that fantasy, my cock suddenly stood at full attention.

I stared down at it with gloomy eyes.

Damn it… I hate this. I hate myself for imagining my own daughter like that.

This body has an absurdly strong sex drive. The moment any erotic situation appears, I get rock hard whether I want to or not.

I was mentally singing the national anthem to calm myself down when A-yeong’s voice called from far away.

“Dad! Couldn’t you find them?”

I couldn’t stall any longer. It would look weird.

“I found them! I’m bringing one!”

With no other choice, I hunched over to hide my erection as best I could and left her room with the pad.

I walked to the bathroom door and shouted.

“A-yeong! I’ll leave it right in front of the door!”

“Thanks, Dad!”

“Yeah, no problem!”

I set the pad down and turned to leave.

At that exact moment, the door suddenly burst open. I didn’t even have time to react.

There stood A-yeong, frozen in shock, eyes wide.

“D-Dad?”

Two perfect peaches appeared right before my eyes.

Two glistening white mounds, still wet from the shower, filled my vision.

Plump. Perfect.

Her breasts were so flawless I nearly swallowed my tongue.

When the hell did my daughter get this big?

That small, adorable child… when had she grown into this?

The realization of her mature body hit me. My half-hard cock instantly surged back to full erection.

I froze, mesmerized by those soft-looking, bouncy breasts. A-yeong froze in embarrassment.

How long did we stand there? I felt her gaze slowly travel downward.

Wait, hold on.

If she looks down any further, she’ll see my massive hard-on.

Sure, I was wearing pants, but there was no hiding the massive tent I was pitching.

If A-yeong realized I was lusting after her body… I couldn’t imagine the sense of betrayal she would feel.

The man who took her in and raised her was now lusting after her. The outcome was obvious.

If my pure love and affection for her were misunderstood, I wouldn’t be able to endure that pain.

The moment I thought I might lose the first real family I’d built since coming to this world, my swollen erection began to wilt.

Get a grip, Park Seong-chan! Are you really going to destroy our precious family bond just because you can’t control your lust once?

With my erection gone and my own harsh scolding ringing in my head, my body finally started listening again.

I forced my stiff limbs to move and gently closed the door.

Click.

…

…

Silence filled the house.

A moment later, A-yeong’s apology broke it.

“I-I’m sorry, Dad! You said you’d leave it, so I thought you already had…”

Her voice came through the door, slightly muffled and high-pitched.

…

“I’ll be more careful next time…”

Her dejected tone snapped me back to reality. I was terrified she might revert to the timid girl she used to be because of me.

I hurriedly shouted to clear up any misunderstanding.

“It’s not your fault, A-yeong! Dad was wrong too. I’ll be more careful from now on.”

There was a brief pause, then ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the rustle of clothes. A-yeong emerged dressed and spoke to me.

“You waited a long time, huh? Let’s eat…”

“Yeah…”

And so, for the first time in ten years of living under the same roof, we ate breakfast wrapped in awkward silence.

The meal was… quiet.

“Thank you for the food, Dad.”

A-yeong stood up quietly after finishing. I spoke to her.

“Yeah… A-yeong, I’ll drive you.”

“It’s okay, Dad. You’ll be late if you take me.”

The clock showed 8:40.

It took about ten minutes to get to work. If I drove her, I’d be late.

But still…

“It’s your first day, though…”

“I’m an adult now. You don’t have to do that much. Thanks anyway, Dad.”

She walked over with a reassuring smile, then bowed her head slightly and kissed my cheek.

Chu.

Then she dashed out the door.

“Dad! I love you! Have a good day at work! I’m off!”

“Yeah! You too, A-yeong! I love you too!”

That surprise kiss after so long warmed my heart more than I expected.

“Alright… I got an affection buff from A-yeong. Time to go work hard.”

With that, I headed to the lab.

“Hmm-hmm~”

Maybe it was because A-yeong had showered me with love earlier, or maybe it was pride in my amazing daughter getting into the top university. Even while doing boring, perverted, and tedious research, I found myself humming.

When my colleague saw me like this, he asked why I was smiling.

“Whoa, you actually know how to smile?”

“What the hell, man? Am I not allowed to smile?”

He grinned and answered.

“It’s just surprising. You always walk around with dead-fish eyes. So what’s got you in such a good mood?”

“Listen to this. Our daughter got into Hanam University. Today’s her first day. What do you think?”

“Hanam University? The number one school?”

My colleague’s eyes widened in genuine shock.

My daughter really is incredible.

Might as well rub it in a little more. He has three sons, after all.

“Yeah. And when she left the house she shyly yelled ‘Dad, I love you!’ It really… heh… it hit me right in the chest.”

“You lucky bastard. My son just scratches his back and goes ‘Dad, give me some allowance.’ Guess daughters really are the best, huh?”

Our daughter is pretty affectionate, yeah.

I was proudly bragging about my daughter to my colleague when a chilly voice cut in from the side.

“I see. So how is the research coming along?”

It’s the senior.

I instantly straightened up and gave a mid-presentation on our current results.

“No abnormalities in the research. We’ve checked 23 out of 120 chemical compounds aimed at reducing the side effects of the 20x sensitivity enhancer.”

“Hmm… As expected of Senior Researcher Park Seong-chan. As long as you keep working properly, I won’t complain.”

The senior patted my shoulder and praised me. I bowed my head in thanks.

“Ahaha… Thank you.”

“By the way, you said your daughter got into Hanam University?”

“Yes. I’m truly proud of her. I didn’t do much to help, yet she got into such a good school.”

“Really? Congratulations. But do you actually know what kind of university Hanam is?”

What kind…?

When I asked A-yeong, she only said it was the best university in the country.

“From what my daughter told me… it’s the best university in Korea. That’s all I know…”

My boss’s eyes flashed as he looked at me.

“I see. You know it’s a women’s university, right?”

“Yes, I’m aware.”

“And yet you still sent your precious daughter there… Does that mean you’ve prepared yourself?”

“Sorry? What do you mean by that?”

What was he talking about? Prepared?

When I showed genuine confusion, the senior looked at me with an expression of pure disbelief.

“You really sent her without knowing anything? Sigh… You said your daughter doesn’t have a boyfriend, right?”

“Yes, that’s correct.”

“She must really adore you.”

“Pardon?”

“You’ll find out soon enough. Oh, and since Hanam University is directly linked with our National Pleasure Research Institute, she can just come work here after graduation.”

With that, the senior left, muttering things only he seemed to understand.

“What the hell was that about?”

“Dude, you know how he is. Total fourth-dimensional weirdo.”

“Well… yeah, I guess.”

After that, I continued chatting and bragging about my daughter while doing research with my colleague.

Meanwhile.

“Alright. Since today is orientation, I’ll be handing out a simple assignment. Students, please check the assignment tab in your e-classroom. The deadline is next week. Any questions?”

One female student raised her hand.

“Um, does the partner have to be anyone specific?”

“No. It can be a lover you care about, a family member, or even someone at a volunteer center. However, you must film it exactly according to the instructions written on the assignment.”

“Thank you!”

The professor picked up the microphone again. When no one else raised their hand, he concluded the lecture.

“If there are no more questions, we’ll end today’s class here. Thank you for your hard work.”

Applause filled the room as the lecture ended.

On her way home, Shin A-yeong fanned her burning face with ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠her hand while staring at the assignment posted on the e-classroom.

So basically… I have to do this with Dad?

This… this thing…

If I tell Dad… will he help me?

He’ll probably get mad…

Shin A-yeong fidgeted with her hands the entire way home.
