Chapter 5 – Jaja Alba.
“I will treat you as my sister.”
“Draw it.”
A week after the episode of My Sister’s Mental Illness aired.
Female writer of adult stories + She was evaluated as having improved writing skills, and the number of readers was increasing day by day.
I honestly hate to admit it, but I have no choice but to admit that my sister was good at marketing.
The number of favorites exceeded 2,000, and the number of notifications reached more than 200. And the total number of views exceeded 300,000.
That’s almost as much as someone who works part-time.
And then, the bean paste started falling on me too.
They decided to give me 10% of their profits every month.
“I didn’t know that the exclusive contract would be successful.”
Hehe. How do you think? This sister’s skills.”
“Admit.”
“Praise me more.”
“Noona, Jjangjjangman.”
Haha!”
My sister’s pride is sky-high.
In times like this, you should do better. Well, I guess it will take care of itself.
All I can do now is take care of my sister’s mental health.
The more a person is full of pride and vanity, the weaker their mentality is.
“I’m going out. Are you okay today?”
“…It’s okay. I’m not a slut.”
“It’s like getting hit by a rag──”
“What?”
“No.”
Of course, I am not receiving allowance from my older sister for free.
There is one condition.
“Can’t… In the evening?”
“I have to go to work tomorrow.”
“No way… I can’t help it.”
“…I’ll try my best”
That is, once a day, I help my sister research her sexual behavior.
『
So how did this happen?
The incident goes back a week.
“I’ll come back from my part-time job.”
“…Huh.”
Every time I saw my sister, all I could think of was her sucking my dick, so while I was in an awkward mood, all I could think about was her even at my part-time job.
The feeling that after your first kiss, the lingering feeling doesn’t go away until the next day.
It’s not even a kiss with my sister, and I got her goddaughter, so it’ll probably last a few days.
It’s so awkward, what should I really do?
“I’m here.”
“…”
Even though she came from her part-time job, she usually came out and said hello, but today she didn’t do that.
Of course, even if it were me, it would be the same.
“Huh?”
I was wondering if the house was too quiet, so I looked in the shoe cabinet just to be sure, but the three-stripe slippers I always saw were still there.
I don’t think I went out, but the house was very quiet for that.
Since the door is closed, it looks like he’s probably sleeping.
‘I didn’t even eat.’
Even though I had just washed the dishes, there were no droplets of water on the table or sink.
And my sister is a lazy person who doesn’t do the dishes unless I force her to, so I’m sure she hasn’t eaten.
“Sister. Eat.”
“Hey.”
“Minyoung.”
No matter how much I knock, my sister doesn’t respond.
The moment I opened the door, wondering if he was dead,
“Sister. Now—”
She was sitting with her stomach down.
『
“…Fuck.”
“Aaaaah!”
My older sister, who saw me and screamed, got under the blanket.
There was no reaction for some reason, so I guess he was wearing earphones.
“You crazy idiot, you should knock and come in!”
“I knocked a few times.”
“You should have done it harder!”
“…Isn’t it better than someone who didn’t do anything at all?”
I also got caught by someone who didn’t knock while jerking off.
Everyone is self-employed.
“But why did you do it all of a sudden?”
“Oh, I don’t know, get out!”
Things started flying at me, so I took refuge in the living room.
‘My sister masturbates too…’
Dating is also dating, and since he asked me all kinds of things, I honestly thought he didn’t do anything like that.
I don’t really have any intention of saying anything about my sister masturbating.
‘Under… Fuck…’
The problem is that now that my sister has started to suck, I have seen a scene where she is sucking again.
He was clearly lying on the bed, legs spread wide.
I vaguely saw that the gray cotton panties were stained a dark color.
No, no matter what, this isn’t it.
Even though we have seen everything we can and cannot see. There’s no way I could stand to see my older sister.
Why is my dick hard?
Even though my pride is hurt, I can’t help but think of my older sister’s face.
You have to keep it a secret for the rest of your life.
“Ha…”
I didn’t think I would be able to get sick anyway, so I cooked and ate cup ramen by myself.
It was already awkward, but now it’s so awkward that I don’t think I can watch it──
“…Hey.”
“Huh?!”
Surprised, I turned towards the sound and saw my older sister sticking her head out.
“When are you going in?”
“Ah. I almost ate it all. Just wait a moment.”
“Eat it quickly.”
With those words, I drank the remaining ramen almost like soup, went into my room, and closed the door.
It looks like my sister is going out to take a shower.
Normally, I would have gone without any problem, but now it doesn’t make any sense.
At the time, I was in a state of self-praise, wondering where else there was such a good younger brother.
“…”
My cock responded to the sound of my sister showering.
Now I can almost imagine my sister naked.
When I saw it once in the past, I really didn’t think anything of it.
Now that I look at it, there’s nothing about it that isn’t my taste, such as that slim waist and massive breasts.
I feel like I have become a slave to sex.
This time, I was afraid that I would get caught if I hit my daughter, so I lay down on the bed with my clothes on her clothes.
When my sister sleeps, I have to take a step back.
‘Finished.’
The sound of water falling stops, and soon the bathroom door opens.
The sound of footsteps gets further and further away, and the sound of water pouring from the water purifier begins to be heard.
It’s enough to upload a video with the title [The reason why men are good at social media;;], So it’s clearly visible what my sister is doing.
If I just go to sleep like this, it’s finally time for me…
“…?”
I’m sure I can hear footsteps heading towards the room, but they’re getting closer and closer.
“Hey. Are you sleeping?”
“…!”
And the sound of my sister outside.
Hurry up and go to sleep. Why did you come here?
“I’m going in.”
“…”
When I pretended to be asleep and didn’t react, my sister opened the door.
Fortunately, I didn’t get caught because I was already covering my eyes with my arm and pretending to be asleep.
“…Why are you going to bed so early?”
I felt sullen and wished I had just left, but instead of leaving, I looked around my room.
The rustling sound was quite annoying.
I felt that rustling sound underneath me.
“Because you… Did something wrong…”
What did I do wrong to touch my pants?
‘And why are they taking it off!!’
As my older sister forcibly removed my pants, the waistband of my pants caught on my dick and then went down.
Next, my panties went down in the same way.
“Even after this, I can’t wake up. It’s so bad.”
What should I do? I didn’t even sleep in the first place.
My sister grabbed my dick so casually that I wondered if she was intentionally pretending not to notice.
I thought I would, but I didn’t think I would actually catch it.
“Oh…”
“Hey.”
“Ouch! Fucking surprise!”
“What are you doing?”
“When you wake up, you say you woke up…!”
Finally, I couldn’t bear it anymore and woke up, my dick standing next to my sister’s little face.
The cock twitched and lightly touched my sister’s face.
“Stop talking bullshit. What are you doing?”
“…”
My older sister looks at me and my dick alternately and looks at each other.
I couldn’t understand its meaning right now.
“What should I do about this thing that keeps coming to my mind…”
“…”
Should I call this fortunate or not?
My sister had the same thoughts as me.
For some reason, he was openly masturbating.
“Well, then what do you want me to do?”
“Just stay still.”
“Still…?”
“I’ll take care of it…”
After saying that, my sister adjusted her posture and climbed onto her bed.
He came between my legs, giving off a dirty smell, and shyly put his cock in his mouth.
“Ugh…”
At first, she started touching my dick with her lips as if kissing me, and then she started sucking it with pleasure.
The sticky sensation of being slowly swallowed starting from the glans and being touched by sticky mucus.
As the lingering memories of yesterday had not yet gone away, I was unable to express my feelings when the scene was recreated again.
“Whoop… Jooup… Haup…”
Have I gone as far as I can? I don’t feel any discomfort when I see him quietly closing his eyes and engrossed in sucking.
As if it were natural, I was stroking my older sister’s head for no reason.
“Right.”
My sister seemed to not like me, but she suddenly glared at me.
“…No?”
“Boo.”
He shakes his head, still holding the cock in his mouth.
I’m glad I don’t hate it.
“Prepare to pull it out slowly…”
The technique became more natural than yesterday, and the feeling of ejaculation came quickly.
I couldn’t hold back any longer as the eyes urged me to cum quickly.
“Ugh.”
“Ugh…!”
I shake my back and ejaculate, but the warm feeling doesn’t go away.
I looked down and saw that my sister was still holding my dick.
“What, are you okay…?”
“Ugh…!”
The semen pouring out goes right into my sister’s mouth.
However, my sister doesn’t stop sucking.
Do you know that if you suck while ejaculating, the stimulation will be stronger?
“Jjuup… Jjub… Paha…”
Making dirty noises, my sister when she wore it on my cock.
In between, thick, opaque saliva was hanging down, just like the pornographic video I saw yesterday.
“Heh… Wow!”
I thought he was laughing, as if he was proud of me, but he immediately started to vomit, so I brought him tissues.
“Why did you swallow that…”
“I’m curious about the taste of semen…”
“What is it like?”
“It’s so fishy…”
He kept spitting in strange places and went to the bathroom to brush his teeth.
“I will never eat again.”
“Who told you to eat it?”
“What should I do if I’m curious about historical evidence?”
“What the…”
You can find it all over the internet, so why bother checking?
Of course, this is a good thing from my perspective.
If you have any questions in the future, I’m sure you’ll come to use my dick.
“Minwoo.”
“Why.”
“Do you want to work part-time?”
“…What part-time job?”
“Dick part-time job.”
“…”
I had no idea those words would come out of my sister’s mouth.
Since I’m a writer of adult stories, I guess words like that don’t mean anything to me anymore.
“Can I keep using your dick? If you make a lot of money, I’ll give you part-time salary.”
“It’s a bit weird that mine is for research purposes.”
“You are the best sample…”
I can’t turn away my sister who sincerely asks for this, and honestly, it’s good for me too.
In fact, there is absolutely no reason to reject it.
I was just showing off my pride for a moment.
“Okay. Deal.”
“Oops!”
From that day on, my sister studied my dick every day.
『
Back to the present.
When I returned from my part-time job, there was a small envelope sitting on my desk.
There was a considerable amount of money in the envelope, 100,000 won.
“I’ll use it well, sister.”
“I guess so…”
100,000 won for researching a dick. It can’t be a really crappy part-time job.
No matter how you look at it, it is a structure that only benefits me.
“Oh, and today…”
“Of course. It’s okay.”
I have already learned the taste of money and the taste of older sisters.
I couldn’t stop here.
