A Side of My Daughter I've Never Seen

The wet, obscene sounds of flesh slapping against flesh filled the room.

"Mmmh… ahh… ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠haaang!"

"Even after I fucked you that hard, you're still dripping like crazy. You really love it when I stir up your bitch cunt, huh?"

"Y-yes! I love it! Keep pounding this pussy that's addicted to your cock…♡"

Han Jihoon was thrusting into Kang Iseor from behind as she lay face-down on the bed. Through the slightly ajar door, Kang Min-ah watched in frozen shock.

'I-Iseor…?'

Even from a distance, the sheer size of the penis was violent. It was slamming roughly in and out of her daughter's lower body. The hole stretched around that massive thing was spread so wide it looked painful, as if it might tear.

But what shocked Kang Min-ah even more was something else entirely.

Her daughter's face as she looked back at Jihoon, panting desperately. There was no trace of pain or suffering in her expression—only pure, blissful moans.

"Nngh… haa…! Your cock… your cock feels so good I'm going crazy! Getting my womb pounded like this is incredible…!"

'Our Iseor… saying things like that…'

Her mind spun at the sight of her daughter behaving in a way she'd never seen before. The girl who had always acted like she had no interest in men was now spewing such vulgar words.

Yet it wasn't just Iseor. Jihoon's behavior confused her even more.

Squelch! Squelch! Squelch! Squelch!

"While you were waiting alone at home after your mom left, you were only thinking about getting fucked by me, weren't you? Don't tell me you couldn't hold it and masturbated?"

"Hngh, nooo… I held it in because I wanted to do it with you…!"

"I don't believe you. Tell the truth!"

Smack! Smack! Smack! Smack!

"Hyeeek! I did! I couldn't wait for your cock so I touched myself…!"

His condescending attitude toward his lover and the violent movements that seemed focused entirely on satisfying his own desires were completely different from the gentle, diligent young man she knew.

Of course, she didn't think his usual responsible demeanor was fake or that he was hiding a violent nature. Even with almost no personal sexual experience, Kang Min-ah was a professional who had handled countless sex counseling cases. She knew that couples often engaged in high-intensity dirty talk and play during intimacy.

But knowing that didn't make it any easier to watch her own child's unfamiliar side.

This was her first time witnessing such raw sexual activity in person—and the participants were the boy she'd thought of like a son and her own daughter.

"Hngh, uht! Ngh…! Jihoon, I'm—haah! I'm gonna cum…!"

"Noona, how many times is this now?"

"Haa, haaang… I don't know… I've cum so many times I lost count…!"

Beyond simply accepting his enormous member, Kang Iseor was actively shaking her hips, slamming her sex against him. The good girl who always listened to her mother despite her complaints now looked like a beast consumed by carnal lust.

Completely unaware of her mother's gaze, the daughter convulsed violently as she reached climax.

"Haaahhhhhng…!"

Kang Min-ah's eyes widened. This was the phenomenon called orgasm—the one she'd only read about in papers or heard about during consultations, never experienced herself. For this one moment, even she was mesmerized by the sight like a curious adolescent.

"Haa… haa…"

"Noona. How selfish, cumming all by yourself?"

"S-sorry…. I'll use my mouth instead."

Iseor turned around and knelt in front of Jihoon's crotch. Without the slightest hesitation, she took the cock that had just been inside her into her mouth.

"Hngh… mmm, uup… hngh."

Slurp… slurp, lick, slurp…

Her skilled tongue work and the natural, unhindered movement of her head made it seem like she'd done this countless times before.

"Noona, I'm cumming…!"

"Mmmph!"

Even as the messy semen filled her mouth, Kang Iseor still wore an expression of pure bliss. She even showed him the load collected in her mouth as if showing off, then swallowed it down her throat while savoring the taste.

"Haa… your cock is still so hard…"

"You came that much and you're still not satisfied?"

"Yeah… even after cumming I want more. Mom said she'd be home in the evening, so fuck me more until then…♡"

The two of them pressed their bodies together once again. This was enough. Any longer and she might get caught. With that thought, Kang Min-ah carefully closed the door.

"Haa… haa…"

'What did I just watch…?'

Back in her room, she had only been watching, yet her forehead was drenched in sweat. Her heart was pounding so loudly she worried it might echo through the house, and her breathing was ragged.

'Those two…'

She replayed the scene she'd just witnessed. The excessively explicit language and violent movements. No matter how she thought about it, it seemed less like normal affection and more like a game focused purely on pleasure itself.

She didn't think the act itself was wrong. Occasionally engaging in special ways of making love could greatly help maintain a relationship between couples or lovers.

But from a professional's perspective, if they kept repeating such intense play and powerful stimulation, it would indeed become a problem.

'Once the body gets used to strong stimulation, it starts craving even stronger stimuli. That could lead to interest in dangerous methods…'

Repeated masturbation that applies strong pressure to the penis could lead to boredom during actual intercourse. Similarly, constantly chasing only intense stimulation during sex could bring side effects in some form.

'I need to help those two maintain a healthy relationship.'

Kang Min-ah inwardly vowed to guide the daughter she loved and Jihoon, whom she cherished like a son. Yet even as she thought this, the scenes she'd ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠just witnessed kept flashing through her mind.

Her daughter's face trembling in joy from an orgasm she'd never experienced herself. And Jihoon's cock that had been moving in and out of her—the massive, grotesque thing that frightened her yet, for some reason, she couldn't look away from.

She had clearly peeked out of worry, but those images kept haunting her.

'…This won't do. I'll sleep for now and think about it tomorrow.'

To calm her racing heart, she finished her bedtime preparations and forced herself into bed. But she couldn't shake the distracting thoughts, and it was a long time before she finally fell asleep.

"Mmm…"

I woke up from a deep sleep. At the same time, I felt a soft sensation. When I looked down, I saw a naked Iseor-noona burying her face and breasts against my equally naked chest.

"You're awake?"

"When did you wake up, Noona?"

"Not that long ago. Sniff… haaa…"

The way she was inhaling my scent with an ecstatic expression reminded me of someone who had given up quitting smoking and was finally taking a drag after a long time. Even though she said she'd only woken up recently, her already dazed eyes were both amusing and adorable, so I silently stroked her hair.

"…Hehe."

"Why are you laughing?"

"Nothing. I was just remembering how surprised Yuna sounded on the phone yesterday. Was it that shocking that my mom is Kang ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Min-ah?"

"She's as famous as a celebrity, so it's understandable. I was shocked too when I found out how well-known you are, Auntie."

"Is that so? Sniff…"

She casually breathed in my scent again. Watching her, a question suddenly occurred to me.

"What does it feel like having a famous mom? Is it nice being able to brag about it?"

"Hmm… for me, it was less about feeling good and more about feeling sorry."

"Why?"

"Mom's been famous since I was little, and since there was no dad, she worked non-stop to raise me well by herself. I'm grateful, but I felt sorry that she had to struggle so much."

"I see. I didn't know you felt that way."

Iseor-noona continued.

"These days she's been reducing her work, and she said she's handing over the counseling center director position to someone else, so she won't have to struggle anymore. From now on, I need to take care of her."

"Our Iseor is such a good daughter. I should give you a kiss as a reward."

"What are you talking about?"

She spoke grumpily but looked up at me and closed her eyes.

"What?"

"…You said you'd kiss me."

"Haha, alright."

When I gave her a light kiss, she looked satisfied, then went back to her pouty expression and continued smelling me.

"Still, isn't it good that Mom's beautiful?"

"Well… when people compliment Mom on being pretty, I do feel strangely proud."

She must have heard countless compliments. That's how exceptionally beautiful Auntie was. Even I, who had known her since childhood, thought she was one of the most attractive women I'd ever seen. Even though she was in her late thirties, her beauty remained, enhanced by the mature charm unique to adult women. Honestly, in my mind, Iseor-noona, Yuna, and Auntie formed the top three in appearance.

'If I were seriously single and completely unrelated to Auntie, I might fall for her at first sight if we met on the street.'

As I was thinking that, Iseor-noona, who had been clinging to me without getting tired of it, let out a sigh.

"Sigh…"

"What's wrong, Noona?"

"It's just… I hope Mom meets a good person now too. I don't want her to only worry about me. I hope she finds her own happiness."

"What is this? Are you saying nice things again just to get another kiss?"

"No, I'm not? But you can still kiss me."

After our lips met and parted once more, a loud growl came from my stomach.

"I'm hungry. Noona, let's eat."

"Okay. Let's wash up first."

We showered ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠together in the bathroom attached to Noona's room and got dressed. Then, without thinking much, we went out to the living room together, only to find—

"Mom?!"

Auntie, who shouldn't have been home at this hour, was standing there.

"Did you sleep well?"

"Ah, hello."

"Yes, Jihoon."

Since we'd done all sorts of things thinking she wasn't home, I felt embarrassed. Iseor-noona also looked visibly flustered.

"Mom, didn't you say you'd come in the evening? It's still daytime…"

"A friend had something come up, so Mom came back early too."

"When did you get here?"

"Let's see. It was around dawn, but I fell asleep right away, so I'm not sure."

If she fell asleep immediately, maybe she didn't hear me and Noona?

"Are you going to eat? Should Mom make something?"

"No, we'll cook."

"Really? Then Mom will rest in her room. Jihoon, eat and relax before you go."

"Yes, thank you."

Auntie went into her room like that. Noona and I exchanged relieved glances without making a sound, but an uneasy feeling lingered.

After eating and hanging out at Noona's house until her broadcast time, I returned home.

'Did Auntie really not know…?'

We'd gone at it hard thinking she wasn't there, so I wondered if the sounds hadn't reached the living room.

'…I don't know. Since she didn't say anything, even if she heard, she must have understood.'

I stopped worrying about the unanswerable question and took out my phone. I wanted to check the Sexmuwiki that I hadn't been able to look at properly at Noona's house.

'Hmm. Nothing much has changed.'

The only addition was a record in the "Events and Incidents" section. Well, we had just done what we usually do in Noona's room, so that made sense.

'Maybe I should call Yuna and then play some games.'

My finger was moving to close the app when—

"Oh, what's this?"

It had been a very long time since I'd seen a permission level increase notification. It had been quiet for a while, but it seemed the experience gauge had been nearly full.

Now it was time to see what the level-up reward was. When I saw the following notification, my eyes widened.

A new document had appeared earlier than I expected. However, unlike when I received the second document, my expression remained relatively calm.

'Yeah. What was bound to come has finally arrived.'
