"Haa... fuck..."
I masturbated again while looking at m0m's Instagram photos, feeling self-loathing.
The guilt melted away like candy dissolving in water, and lust filled my lower body instead of anger.
Yesterday and today too... why did I get so turned on?
I had secretly watched m0m having sex with Dad many times. I had heard m0m screaming lustfully while being violated by Dad as if being raped many times, so why now... why do I get an erection listening to m0m being fucked by Kwak Young-cheol?
Then I suddenly realized, Kwak Young-cheol is not Dad.
He was a 'man', not 'family' like Dad.
Kwak Young-cheol was a 'man', not 'family'.
Dad, who is family, violating m0m, his wife, and
'Man' Kwak Young-cheol violating 'm0m' were completely different issues for me.
Yes.
I had to admit it.
I get sexually excited... no, let's drop the pretense of being refined.
I get turned on when m0m is viewed with lewd eyes by 'men'.
I get turned on when others look at m0m as a slutty woman, with eyes full of desire wanting to fuck that big ass.
Unconsciously, I get hard imagining m0m being pinned down and violated by them.
I got turned on listening to m0m's white, slim body being violated sadistically, insultingly, as if being raped by Kwak Young-cheol's pig-like body.
And today,
I confirmed that tens of thousands of people are looking at m0m with those eyes, wet with lust.
Thinking about that, an unspeakably lewd, perverted pleasure came over me uncontrollably.
I know it's wrong, but my mind couldn't resist this pleasure I was feeling for the first time in my life.
"Huff... huff, huff..."
A s0n masturbating while looking at his m0m's Instagram photos.
The worst, right? The emptiness and hollowness I usually feel after masturbating. I had to feel that doubled, with guilt on top.
=====
January 7th
Winter of senior year is really leisurely.
With the college entrance exam over and applications all submitted. It's just a time of endless waiting now.
I killed time hanging out at the PC room with Gyu-tae, who applied to the same university as me (though different departments of course).
Ah.
I haven't masturbated thinking about m0m again since that day.
The mental aftereffects were too big, I guess. I tried my best to restrain myself.
Of course it didn't go exactly as planned. Sometimes I would unconsciously go to m0m's Instagram and secretly look at her photos.
And when I occasionally saw m0m's defenseless appearance at home, I had to forcibly hide my erection. She would walk around in front of family wearing string panties with a loose tank top or dolphin shorts that showed half her butt with a crop top.
It used to not bother me at all before, but now it's different.
It's shameful, but since I've already crossed an irreversible line thinking about m0m twice, I can only suppress it as much as possible. I can't go back to before and look at her with indifferent eyes as if nothing happened.
I just hoped m0m wouldn't know about these thoughts of mine.
So I tried to stay out late playing before coming home.
The problem is when I come home late...
That bastard Kwak Young-cheol would come over every few days and shamelessly sit there acting like our new dad.
"Oh, Hyeon-seong is home?"
"Ah... hello"
"This must be the most fun time, right? Play a lot"
Sitting right in the middle of the living room like it's his own house, greeting me as if nothing happened... he acts so naturally like he's already part of our family, and it's really burdensome for me to go along with it.
...Well, legally this is his house and we're living here for free, but let's not cowardly get hung up on facts.
And below the sofa where Kwak Young-cheol sat with his legs spread wide like the head of the household, m0m was kneeling demurely at the tea table peeling apples as if she were Kwak Young-cheol's wife. (Something I never saw when Dad was around)
"Hyeon-seong is home?"
"Yeah... I was out with a friend"
"Did, did you eat?"
"I ate. I'll go to my room first"
I tried to act as normal as possible as I went to my room.
It was hard to see m0m blatantly acting like that in front of us as if she had already remarried Kwak Young-cheol.
Sigh. No matter how I look at it, that Kwak Young-cheol... he really pisses me off.
Angrily, I quickly opened the door and went into my room...
Shit.
This is crazy.
Why is she like this again???
"Hey. What are you doing?"
"What? Knock before you come in"
My sister who shares the room with me. Kang Mi-hyun was rolling around wearing just panties, topless with no bra. Of course I could see those big white breasts at a glance.
She was so focused on her phone that even though I came in, she just kept focusing on sending some message and didn't even think to put clothes on, instead getting annoyed at me.
Ugh this crazy bitch.
She often undressed freely before too, but that was when changing clothes. It was rare for her to be completely naked like this, but today she's really acting up.
"Put some clothes on you crazy bitch, that ahjussi is here too"
"What are you saying. But why are you home later than me for once?"
"Shut up"
Hah.
But there's another problem.
I had reflexively gotten an erection because of m0m. Fuck...
But in my sweatpants, my quite large dick (not to brag) was tenting so obviously.
"Oh you crazy bastard"
"...What now?"
"You just got hard looking at my boobs didn't you? You pervert"
"Are you insane? Don't pick fights and get lost"
It's not because of you, you bitch.
But when she said that... I suddenly became strangely aware of Mi-hyun's naked white body. I really had no thoughts before, but her saying that suddenly made me embarrassed.
And as I turned my head away in embarrassment, she seemed to find it fun and suddenly got up
"You pervert. Getting hard looking at your sister's tits?"
She came over in her panties, smirking and picking a fight next to me. She even thrust her chest out towards me.
Of course since she wasn't wearing clothes, those huge rocket-shaped breasts were aimed at me as if about to launch...
"I told you to leave. There's nothing to see. Hurry up and put some clothes on"
"What. You really did get turned on huh? Why can't you look?"
"What?"
"You never cared when I undressed before, right? Why are you suddenly acting like this??"
"It's not because of you, idiot"
I tried hard to avoid looking at her chest and pushed her away...
Maybe because I reached out without aiming?
Squish!
I accidentally touched her breast. I quickly pulled my hand away but she was already excited thinking she caught me.
"Wow. Now you're openly touching?"
"You crazy bitch. It was an accident"
That squishy feeling lingered strangely on my hand and the atmosphere became too uncomfortable. But Mi-hyun seemed to find it fun.
"Oppa. It felt good touching my boobs right?"
"What?"
"Honestly my boobs are delicious... I'll let you touch them once for 10,000 won. How about it?"
Unable to stand it anymore, I
Smack!
Hit that rock head of hers.
"Ow! Why did you hit me!"
"I hit you because you're acting crazy. Are you really insane? What 10,000 won?"
"It was just a joke, why are you taking it so seriously, geez"
"Do you do that kind of thing normally?"
"Are you crazy? Do you think I'm someone who sells her body?"
She finally grumbled and went back to her spot to put on a t-shirt.
Tired, I also went to my spot and lay down facing away from her.
Hmm...
The feeling of a woman's breasts that I felt briefly just now... for the first time in my life.
Though it was my real sister's breasts, honestly it was a bit sexy.
=====
As I was killing time on my phone in my room,
Kwak Young-cheol and m0m in the living room showed no signs of going to their room.
"Puhaha!"
"Is it funny oppa? That bitch actually said to me..."
When I went out to the living room briefly to use the bathroom, they had even set out drinks.
"Hyeon-seong. Want to have a drink too?"
"No, I'm fine"
"Come on. What fun is there for a young man if you don't even drink? Hey, everyone will be crazy about drinking when you get to college"
"..."
"Ah, remember I told you to try working part-time at my business? Have you thought about it?"
"I'm still thinking about it"
"Alright. Stop thinking and come work. The sooner you gain social experience the better. Look at this ahjussi. I'm living well without even tasting college"
"...Ah okay"
After listening to him talk for a bit, I tried to go back to my room to lie down.
Ah.
Seeing them drinking with no plans to go home...
I thought they would blatantly have sex in the next room again, like last time.
'...'
But... unlike before, this time I wasn't just angry...
As expected, about an hour later the noise from the living room died down... and sounds really started coming from the next room.
'Fuck, it's starting again'
"...Ah... ah"
m0m's lewd voice being fucked by that bastard Kwak Young-cheol.
Unlike last time, m0m seemed to be restraining herself quite a bit as the moans were so quiet they didn't fully penetrate the wall.
It sounded like she was saying something in between, but I couldn't hear that well either.
Is she being mindful of me?
But... I got even more curious. What on earth are they talking about? It seemed like she was saying something between moans but I couldn't hear clearly and it made me more anxious.
After struggling for a while, I finally couldn't stand it and very quietly opened my door and went out to the living room.
"Haa❤... ahhn❤!"
But... the master bedroom door was slightly, just slightly open enough to peek through with one eye. So when I came out to the living room, the moans got that much louder.
"..."
I hesitated slightly, very slightly, then was drawn to that gap as if hypnotized. As I walked on tiptoes to muffle my footsteps, I felt like a thief.
Anyway, I quietly reached the door gap... took a deep breath to calm myself for a m0ment, then started peeking through the gap.
As if to be clearly visible through that door gap, the two people were overlapped in just the right position.
