Early in the morning, Jinwoo woke up.
Despite feeling troubled, his body felt fresh.
Last night, he had a fierce wank using Sohee's panties and, feeling totally spent, tossed them into the washing machine.
He shivered with guilt but felt relief at the same time.
If he had been in Minji's room, who knows what he might have done.
The relief that he hadn't crossed that last line.
Jinwoo really cared for Minji.
Jinwoo and Minji, a cute and lovable younger sister who is three years his junior. With her innocent personality, she had followed Jinwoo closely since they were kids.
She was always cheerful, having been showered with love by all the family members.
Even the strong and fierce Sohee seemed to make an exception when it came to Minji.
Jinwoo cared a lot for Minji.
If there was a fire and he had to save only one family member, it would definitely be Minji without needing to ask.
That's how much Jinwoo cherished his younger sister.
That's why Jinwoo could flee from her room last night.
Despite feeling a strong lust towards his vulnerable sleeping sister...
It was almost a miracle, an act of will.
He preserved his relationship with his sister.
It could continue.
Jinwoo heads to take a shower to cleanse himself after the intense masturbation.
All through the shower, Jinwoo made a vow with a penitent heart never to lust after Minji again.
Jinwoo remembers rushing out of Minji's room without even covering her with a blanket.
After the shower, he walks past the dark living room towards Minji's room.
Minji is cuddled up and sound asleep.
The girl who had been stirring Jinwoo's heart wildly just a moment ago was no longer there.
Only the lovely younger sister Minji was there.
Jinwoo feels relieved again.
Jinwoo gently picks up the blanket that was pushed aside and covers Minji with it.
After watching over Minji for a while, Jinwoo leaves her room.
He intended to return to his own room through the dim living room.
Then, he saw light leaking from the slightly open door of the master bedroom.
A dull sense of unease.
A sound like moaning continued faintly.
Jinwoo approached and peeked through the crack of the open door.
There lay his mother, bathed in the bright light of the room, in the same position as when she was breastfeeding Minji.
Her eyes were covered with a blindfold to block out the light, and her mouth was erotically opening and closing.
Her lavender silk gown was open towards the door where Jinwoo stood, and one hand was inside her panties, rubbing irritably.
In her other hand was Sohee's panties.
The black panties of Sohee that Jinwoo had just poured a tremendous amount of semen into.
Jinwoo's heart pounded again, aroused.
'Why mom?'
Jinwoo was confused.
He couldn't sort out the situation in his head right away.
All he could do was be turned on by the sight of his mother exuding sexual desire.
Jinwoo pulled out his massive cock and grasped it with both hands.
Then, he began masturbating, stroking his hand up and down vigorously.
His mother's voluptuous breasts...
Her elegant and hefty ass...
Her body twisting and vibrating to her movements.
As Jinwoo shook his thing watching her, the feeling of climax approached.
Guilt was nowhere to be found.
He repeated the thought and hesitation of whether to just come on his mother's breasts several times.
Then, he thought of Minji, asleep.
The vow he had made earlier had crumbled all too easily.
But even while making that vow, Jinwoo knew.
He might someday commit that act he wasn't supposed to.
Jinwoo adjusted his pants and carefully returned to Minji's room.
Minji was still sleeping soundly, unaware of anything.
Jinwoo lowered his pants and brought the head of his hefty cock close to Minji's face.
Then, without any caution, he shook his massive pillar that couldn't be fully grasped with one hand.
Jinwoo recalled the scene of Minji suckling on their mother's breasts.
Those lips that had been on her mother's nipples were right before his eyes.
Jinwoo's tip brushed against Minji's lips.
At the brink, the sharp stimulation as if struck by electricity traveled up his spine to his brain.
In a burst, Jinwoo's semen exploded.
The ejaculated semen covered Minji's face.
Her eyes, cheeks, nose, mouth; Jinwoo was breathing heavily.
Right before his eyes was Minji's face smeared with the semen from his body.
Jinwoo placed his finger on Minji's lips, gathering the nearby semen and gently spreading it in a circular motion.
It was as if accepting his sexual guilt was a ritual act.
* * *
Recalling the memories of the previous day, Jinwoo felt his body heat up.
It was a mix of surprise, pride, embarrassment, and torment.
He went down to the bathroom on the first floor.
Jinwoo usually uses the bathroom on the second floor after waking up.
He went down to the first-floor bathroom because he wanted to check the traces of the surreal night before.
The laundry room, which also served as a dressing room, was in front of the bathroom.
He opened the lid of the washing machine.
The laundry inside was turning.
The items proving last night's activities were already being processed by his mother.
While it was regrettable, a thrilling excitement arose.
After the climax, he imagined his mother alone handling the aftermath with her body still tingling from excitement.
He quickly washed up and went to the kitchen, where his mother and Minji were preparing breakfast.
Seeing his mother's body, he recalled the wriggling figure from the night before on the bed, blindfolded and sniffing his semen.
"Jinwoo, you woke up early today?"
His mother greeted him with a smile.
Her voice and demeanor seemed no different from usual.
Surely she must know about Jinwoo masturbating with Sohee's panties after seeing her exposed breasts...
Jinwoo was now certain that his mother had been awake when he flicked her nipple.
Given the intensity of that hit and the sensitivity of the spot, it was almost certain that anyone would wake up.
If she had awoken from such a shock, it would have been natural to instinctively cover that sensitive spot and get up.
Her body's minimal, restrained twitching was a poor act of someone trying not to be caught awake.
Jinwoo was now fully aware and certain of that suspicious fact he had vaguely sensed.
And now, his mother was acting as if nothing had happened.
If his mother knew that Jinwoo knew, how would that smiling face distort?
Thinking about this made Jinwoo feel strangely thrilled.
"Yeah, I really relaxed and had a good sleep last night," Jinwoo deliberately said to his mother, implying masturbation.
He wanted to see her flustered reaction.
"Did you exercise or something before bed?"
His mother asked calmly.
Was she oblivious, or just pretending not to know?
His mother's naturally casual response made Jinwoo take the conversation further.
"No, not exercise... But you also slept deeply last night after doing the same, right?"
"Ah..ah?"
A slightly raised eyebrow and a flustered expression momentarily crossed his mother's face.
Jinwoo was sure he had caught the meaning of that expression in that fleeting moment—a secretive sensation shared between them sparked.
"I moved Minji after that, right? Slept deeply because of that?"
Jinwoo spoke as if hinting around to his mother.
"Ah~ yeah... Maybe I really slept well last night thanks to you, Jinwoo."
His mother seemed slightly uneasy and suspicious, but she probably thought that Jinwoo wouldn't know about the late-night events.
"Today, I'll make zucchini stew for you~ But maybe it's not your brother's favorite? Still, you should eat a variety of foods! Hehe."
Minji was cheerfully talking again with the face that had been covered in Jinwoo's semen just a few hours ago.
With those vibrant, semen-smudged, rosy lips...
Chattering away as usual.
"Yeah, anything Minji makes is always delicious," Jinwoo said to Minji, making another vow as if.
And then he looked at the mother and daughter alternately with a familiar gaze.
