"Seohee is neat."
Seohee's room looked very ordinary, but for a girl her age, it was quite simple. I lightly vacuumed and finished cleaning, and as I was about to leave, I noticed her computer was on and approached it out of curiosity.
"Hmm, there are no games, and it doesn't look like there's any special internet history... hmm?"
Thinking it wouldn't be polite to dig too deeply, I just wanted to check if she was talking to any strange people, but then I noticed a file.
When I opened a file called "1-1," there were over a hundred files inside.
"What is this..."
There were files with suspicious titles like "Hope for a Sex Slave," "Masochist Stepmom," "Policewoman Trained After Being Raped," and so on, so I checked and found they were all erotic stories.
"She has these kinds of tastes..."
I knew I shouldn't pry too much into my sister's sexual preferences, but this went beyond the ordinary, so I was honestly troubled. Still, since I couldn't imagine having a conversation with Seohee about this topic, I decided in my mind to respect her tastes and just pretend I hadn't seen anything, quickly leaving her room.
"Sigh~ Okay, I didn't see anything. Good, so now only Mom's room is left."
When I entered my mother's room, I was immediately hit with a strong scent, different from my sisters' rooms, that seemed to carry the mature scent of an adult woman, and I started to get aroused.
"Mm..."
As expected, my mother's room was neatly organized, just like her personality, and didn't seem to need any cleaning. At most, I just needed to tidy up the panties and bras on the bed.
"As expected of the president of an underwear company."
Unlike other women's rooms, my mother's had a variety of women's underwear neatly arranged on one side, almost as if they were on display.
Each piece was quite provocative, fitting for my mother's company, whose motto is "Making Women More Feminine."
"Could these be the ones she actually wears?" ... Looking at the displayed underwear, I started imagining my mother wearing them, and my erection grew so hard it felt like it would burst through my pants.
"Calm down, no matter what, I shouldn't do this with my mother."
Suppressing my desire to touch them, I thought I'd just put away the underwear on the bed and leave, maybe watch some porn and masturbate in my room. But when I saw the underwear on the bed, I froze on the spot.
On the bed was a small, red pair of panties, and the area that touches a woman's private parts was darkened with a wet stain.
Gulp.
"Th-this can't be..."
It was hard to imagine my always dignified and confident mother, idolized by many women and admired by men, masturbating. But with such clear evidence in front of me, I couldn't help but imagine her lying on the bed, pleasuring herself in a lewd way.
With trembling hands, I picked up my mother's panties and smelled them. I didn't have any experience, but instinctively I knew this was the scent of a woman's fluids.
Naturally, my erection grew as hard as it could, and I was overwhelmed by the urge to take out my penis and masturbate right then and there.
I also reached for the bra and touched it, and it still felt slightly warm.
"Her fluids haven't dried, and the bra is still warm..."
Looking at the situation, I came to one conclusion.
My mother had masturbated this morning.
Realizing I was in the place where my mother had pleasured herself just a few hours ago broke my last bit of self-control, and I immediately pulled down my pants and underwear, wrapped my penis in her panties, and started masturbating.
Fap! Fap! Fap! Fap! Fap! Fap!
"Ugh! Mother... Mom!"
As I closed my eyes and imagined it, I pictured my mother pleasuring herself on the bed. Seeing my always composed mother undressing, touching her most private parts, and fondling her breasts was more arousing and exciting than any porn I'd ever seen, and I quickly reached the point of climax.
"Right here!! I can't help it."
Feeling like I was about to cum, I grabbed the bra and ejaculated into the panties, dirtying them with my semen.
"Damn, I need to wash these quickly."
After ejaculating, I entered a state of post-nut clarity, quickly understood the situation, and hurried to take the soiled underwear to the washing machine.
"Huh? Wh-why isn't it working?!"
I tried to wash them quickly, but the washing machine wouldn't work. Panicking, I checked it all over, but since I'm no expert, there was nothing I could do.
"Should I hand-wash them? No, suddenly hand-washing now would be too suspicious."
Since I'd never hand-washed anything before, it would obviously seem strange if I suddenly did it now, so I just took the semen-stained underwear back to my room and hid them in the corner of my closet, spending the rest of the time thinking up excuses for later.
Time passed, and my mother, who usually gets home earlier than my sisters, returned home first at 5 o'clock. I tried to act as normal as possible and sat on my bed, praying inside that she wouldn't notice.
Knock knock.
"Heetae, can I see you for a moment?"
"Y-yes!"
Even though she knocked, my mother entered without waiting for my answer, looked around as if she already knew, and went straight to the closet.
"M-mother, wait!..."
I hurried to stop her, but she was a step faster, opened the closet, took out the panties stained with my semen, and reached out to me.
"Shall we have a talk, just you and me, for the first time in a while?"
The day before
"Sigh~ This plan should be good enough, hehe."
After finishing her daily routine, Jihee had finalized the plan she'd been thinking about for a month, and naturally smiled at the thought of carrying it out the next day... "Even though I've been giving Heetae so many hints, he just doesn't get it... I guess I have no choice."
She had long ago started seeing Heetae, whom she took in as a son, as a man and loved him. At first, she was confused by her feelings, but the more time she spent with Heetae, the stronger those feelings grew, and by the time he entered high school, she had fully accepted them.
Although they weren't related by blood, developing a romantic relationship within the parent-child dynamic was nearly impossible, so she devised a multi-year plan as her first step.
Knowing that she was subjectively and objectively very attractive, she thought it would be possible by stimulating his male instincts. At least in front of Heetae, she always wore clothes that showed off her figure and cleavage, and subtly seduced him by swaying her hips or bouncing her chest, arousing his sexual desire toward her.
The plan was successful. After years of effort, it became normal for Heetae's gaze to scan her body when they faced each other, and sometimes she was satisfied to see him unable to hide his erection in his pants. But there was one problem.
No matter how aroused or attracted he was, they were still mother and son. Very few people in the world could cross that line, and Heetae was among the majority who couldn't.
As a result, even when he looked at her with the eyes of a predator for a moment, he would quickly return to his usual son-like gaze, leaving Jihee frustrated.
Of course, she could have made the first move, but ethically and in front of her other children, it was impossible. If Heetae rejected her, she would never have another chance, so she had to be cautious.
That patience led to the current plan.
Masturbate in the morning and leave her scent-soaked underwear on the bed, then break the washing machine.
Assign cleaning duties instead of work, so he would naturally come into her room.
Heetae would take her underwear.
Use this opportunity to get closer to Heetae and finally cross the last line.
The next day
It was a simple plan, but there were many variables, so she chose a day when her daughters would be late and she could come home as early as possible. She sprayed a hard-to-find perfume with a slight aphrodisiac effect in various places in her room and masturbated enough to thoroughly soak her underwear with her fluids.
Masturbating in the morning to get her fluids on the underwear was the hardest part, but the thought of finally being able to be with the son she loved excited her so much that she soaked the underwear even more than usual.
"It's a little embarrassing, but with this, Heetae... hehehe..."
Leaving her panties with her fluids clearly visible was embarrassing, but thinking that Heetae would get aroused and masturbate because of it made her naturally excited. When she saw Heetae in the morning, she was so aroused that her voice unconsciously rose, and even while working at the office, her mind was completely filled with thoughts of Heetae until she finished work and returned home.
