Dohee's Suspicion
"Morning, Dohee. Sleep well?"
"...Yeah."
She had gotten up, finished getting ready for school, and stepped out of her room only to run straight into her stepbrother. Heetae's greeting was perfectly ordinary — but now that she had started suspecting something between him and their mother, even the most mundane behavior looked shady. Without meaning to, she answered him curtly.
She tended to be fairly blunt on a normal day anyway, though Dohee herself never quite realized it, so Heetae took the reply at face value and treated her as usual.
"Go eat."
Their mother called that breakfast was ready. Heetae, Dohee, and her younger sister Seohee all sat down at the table together and began to eat. It was an ordinary meal with nothing strange about it — and yet Dohee's eyes kept sliding sideways, watching Heetae.
Is it because of us? It doesn't really look like anything weird is going on, but...
Once you start doubting everything, even normal things start to feel off. Still, she couldn't find so much as a scrap of real evidence, so Dohee headed to school with nothing but a lingering, uneasy feeling in her chest.
"Hmm... okay! Not bad for today."
"Hah... hah... Thank you."
As a track athlete, Dohee was always out running practice and timing her splits at school. Today's numbers didn't personally satisfy her, but her times hadn't improved at all lately, so she let it slide with a half-resigned shrug.
"Dohee."
"Yes, Coach?"
She had finished practice and was heading for the showers before her next class when her coach called out. Dohee stopped and turned.
"Dohee, is something bothering you these days?"
"Huh? No, nothing like that."
She was wound tight because of her mother and Heetae, but it wasn't anything she could tell another person. So she denied it and casually steered the conversation elsewhere.
"Is it about your times, maybe?"
"Well... Dohee, your ability puts you near the top nationally, but your records haven't shortened at all lately. I wondered if something else might be weighing on you..."
"There isn't. Maybe this is just my limit."
Even saying it left a bitter taste. Every athlete hits a wall someday — whether you break through it depends on your own effort and capacity. She had never once slacked off in training. If her times still wouldn't improve, then maybe this really was as far as she could go. The thought sat heavy in a corner of her heart.
"I see. From where I'm standing, you still have room to get better. It's just—"
"Just?"
"You seem too locked up. Fixate on the stopwatch hard enough and even the things that should get better can get worse. Sometimes it helps to set your worries down and just live a little looser."
"Yes... I'll think about it."
With that, the coach let her go. Dohee walked away with her head in a tangle.
Shhhhhhhh—
Under the shower, rinsing off the sweat, she turned the coach's words over and looked hard at herself.
He's not wrong. I've been getting pretty sharp-edged over my times lately.
Maybe even suspecting her mother and Heetae had just been leftover frustration from stalled records, a sour temper she'd dumped on her stepbrother for no good reason.
Back in high school, almost no one could beat her. Once she hit college, though, more and more athletes started posting better numbers than hers, and the impatience had been building. On top of that, every time they'd timed her over the past three months, her marks had actually been worse than last year's. Urgency had taken root.
"Set it down, huh..."
She had always charged straight ahead with her eyes fixed forward. Maybe, just this once, doing what the coach said and letting go wouldn't be so bad. She decided to take the rest of the day easy — and for the first time in her life, she cut her remaining classes and headed home. The tiny act of rebellion, skipping class for the first time ever, lifted her mood a little. Her steps felt lighter than they had in weeks.
"Op—... I feel a little bad about him, so maybe I'll buy him some ice cream or something."
She used to call him Oppa without thinking. Once she got older it started feeling cringey, so she mostly stopped — but every so often it still slipped out on pure reflex. In front of their mother she still said Oppa; when Mom wasn't around, she called him whatever she felt like.
Beep-beep-beep-beep.
"I'm ho—...?"
Cutting class meant she might get scolded, but if she was honest about how she felt, their mother was the kind of person who would understand. Dohee walked in without a care in the world.
The second she stepped inside, though, that strange smell she had noticed before hit her hard and thick. Frowning, she quietly followed it toward the living room, nose working.
—Nnngh♡ Haaah♡ Hnnaah♡
The closer she got to the living room, the clearer the woman's moans became. Dohee went rigid. It was a voice she had heard her entire life — and yet she had never heard it sound like this. An impossible thought flooded her head.
Mom? No way...
After talking to the coach, she had almost convinced herself the suspicion was just frayed nerves. The voice pouring out now told her it hadn't been empty paranoia after all.
No. There's no way Mom would... It can't be.
Clinging to the idea that Heetae was just watching porn in the living room and the voice only sounded similar, Dohee crept closer — and the scene that unfolded in front of her stole the words right out of her mouth.
Schlick! Schlick! Schlick!
"Cry louder, you sow!!"
"Oiiink!!!♡♡ Yes, Master — oiiink♡♡"
Dohee couldn't make a sound. Believing that her stepbrother and her mother were doing this was already impossible enough — but the sight of Heetae spanking their mother's ass and degrading her, and of their mother happily squealing like a pig, felt like every single thing she had ever known being ripped out by the roots.
Standing still, she felt the world flip upside down. Her legs gave out and she crumpled where she stood, but her brain couldn't keep up with what it was seeing. She just stared blankly at Heetae fucking their mother.
"Please cum in this sow's pussy, Master — fill me uuup♡♡"
Cum? What? Cum? Like... that kind of cum?
The woman in front of her was her mother, and yet the words coming out of her mouth made it impossible to think of her as Mom. Dohee couldn't even turn her head away. She couldn't tell whether she was having a nightmare or staring at reality.
"Hnghnnnnnnhh!!♡♡♡♡"
Heetae really did empty himself deep into their mother's pussy. Jihee let out a feral, animal moan Dohee had never heard in her life, eyes rolling back, drool spilling down her chin.
Their mother collapsed, limp. Heetae scooped her up and carried her toward the bathroom. Luckily, Dohee was on the opposite side of the room from the bathroom door — they never spotted her.
"A dream? Yeah. It's a dream. It has to be..."
Unable to accept what she had just witnessed as real, Dohee staggered out of the house. Thankfully, the sound of running water covered the door; Heetae and Jihee never noticed she had come or gone. Inside the bathroom, they simply started another round of heated play.
"Haaah..."
Out on the street, Dohee looked for somewhere quiet — and ended up checking into a motel by herself for a short stay.
Thud.
"Am I dreaming...? Yeah. It's a dream. If I close my eyes and open them again, I'll wake up in my own bed."
She whispered it like a spell she was casting on herself. Mentally she was already past her limit; she dropped straight into sleep.
About an hour later she opened her eyes, saw the motel ceiling, and the hollow realization hit her that none of it had been a dream. She went blank.
"Mom and that guy... why?"
He might not be her biological son, but the two of them were still mother and son. For them to have sex was a betrayal of every human boundary — something that simply must not happen.
"What if he forced her?"
The shock had scrambled her memory; she couldn't hold every detail clear. But she remembered exactly what Heetae had done to their mother.
"Spanking her ass and calling her a sow? Yeah. He cursed her out. Called Mom a sow."
It was a skewed recollection — but it was also true. Dohee's thoughts started sliding in the wrong direction.
"Right. Mom would never do that on her own. But Opp—... that bastard could. The way he looks at her — all lecherous—!!"
Heetae had harbored feelings for Jihee long before anything physical started between them, and he really had looked at her with hunger. Sharp-eyed Dohee had noticed, of course, and written it off as just a guy being a guy. Now, after what she had seen, the story rewrote itself: her stepbrother Heetae had finally snapped and forced himself on their mother.
"That's it!!! It was that bastard!! I'm sure of it!!"
In truth, if you traced it back carefully, it was Jihee who had started things — but given how Heetae usually acted, suspecting him was almost natural. Pinning everything on him was wrong, of course. But the whole situation already sat outside anything normal reasoning could process, so as a kind of psychological defense, Dohee decided he was the culprit.
"Trash!!"
The second she locked him in as the villain, hatred for her stepbrother came crawling up from somewhere deep. Until now he had only felt a little awkward, a little distant. The moment the idea of a trash Oppa who raped their mother settled into her head, pure hostility flooded in behind it.
"The way Mom couldn't do a thing — he's got some kind of leverage on her. Has to."
Once she started sincerely believing her own half-delusional deductions, a sense of mission took hold: she had to save her mother from Heetae.
"But how..."
She had her direction. She just couldn't think of a method. Then she caught her own reflection in the mirror, and something hardened behind her eyes.
