Chapter 28 – Unbeknownst to My Parents Who Went Abroad, I Became a Lover With My H-Cup Younger Sister and Enjoy Sex.
“Brother! Quickly! Quickly!”
“Okay Siyoung~ Stop it~!”
I am in a romantic relationship with my younger sister, Siyoung.
Send me to take a sticker picture.
Yoon Si-young, 22 years old, 173 cm, 55 kg, 85H cup chest
My brother with big breasts always wears slutty clothes, so whenever I go on a date, I attract men’s attention.
I’m Yoon Seung-hyun, 26 years old. He is 187 tall.
Siyoung and I live together apart from her parents.
My parents are going abroad for business, and we are keeping (?) The house on behalf of our parents who come twice a year.
Si-yeong had been gone since her sophomore year of high school and disappeared with an order (?) To me to protect her sister.
She’s really gone On the day she was discharged from the army, she left a note and left.
And her living expenses were sent to her bank account every month.
3 million won. They said it could be given less because it was too much, but it’s child support.
Siyoung’s child support. No, I’m still young, but where are the parents who ask their children to raise their children!!!
My parents’ business was skyrocketing.
It is a private business, not a corporation, so there is no bankruptcy.
1.1 billion in monthly sales. Even if you take it off, you will still have 300 million left.
As a result, our family grew richer and richer.
The year Si-young was in her third year of high school, I lived quietly so as not to disturb Si-young preparing for her entrance exam.
And on the day of Si-young’s entrance exam, I got up early in the morning, took Si-young to the test center, and waited until the exam was over.
After the college entrance exam, I waited for Si-young to come out with her friends.
Then Siyoung came out and the first thing I saw was Siyoung’s expression.
That looked good It’s 100 percent.
As expected, Siyoung said he knew a lot and liked it.
I went to a high-class restaurant with Si-yeong and her friends with the money I had saved up (?) And ordered everything I wanted to eat.
Friends envied Siyoung.
I live in a wealthy house, my parents are overseas so I don’t nag, my brother takes good care of me, I’m tall, I’m handsome, I have a lot of money.
Oh, it’s not that I’m handsome with my mouth.
Siyoung’s friends are like that. Don’t get me wrong.
As for Siyoung, his shoulder pierced the sky.
After eating like that, I took my friends home one by one, and Siyoung and I went home.
“Oppa, oppa! I think I hit the jackpot on the CSAT! What should I do!!”
“It’s going to be awesome! I lived like a rat for a year!!”
“I’m always grateful for that! Thank you, Orabang”
And that evening Siyoung wanted to drink.
“Brother! I want to drink!!”
“No!”
“Ah why!!! The CSAT is over!”
“Where is the common man drunk?”
“Ah! What’s so good about an older brother like this that kids envy?”
“This? Stop drinking and I bought you a present for the exam, so open it.”
Siyoung continued to complain as he opened the gift.
“No, it’s not that I’m going to drink a lot, I’m just going to try it once, so why don’t you buy me that!”
She grumbled and opened the present.
“No, I said I want to drink it? Huh? Just drink it once… Gyaa!!!! Oppa, I love you!!!!!!”
Seeing the gift, Siyoung ran to me and kissed me.
“Are you feeling better now?”
“Ah, oppa? When did I say that~ Oh brother, I love you!!”
And kisses again
“Do you want to kiss your brother?”
“What do you think? Why? Do you want me to kiss you?”
“What is he saying now”
Siyoung’s final exam gift is the latest adult pad and 1 million won in cash.
I have always wanted an adult pad, so I provided it for child support.
“Brother, thank you very much~~”
“I didn’t buy it with my money anyway. Say thanks to mom and dad.”
“But you can use it only if your brother approves~”
Yes. Her parents also entrusted money to me, and since Si-yeong was still young, she said not to give money, but to let me see what she needed.
“Brother! I’ll grant you one wish! In return!”
“Eh? Sowon? Then don’t let me grow old for the rest of my life”
“No.. I can’t listen to that!! Something realistic! For example, Siyoung’s kiss? Or sleeping with your brother?”
“What? The young bastard has already been stripped!”
“What are you talking about! I’ll do it because you’re my brother! I won’t talk to other guys!!”
I thought it was a joke, so I took it as a joke.
“Then increase it to 2 wishes, that’s a wish”
“Um.. Cole! But we can’t increase it further. We can’t steal gifts!”
“First, a month and a half until adulthood, don’t go out with a boyfriend in the meantime, and when you become an adult, you’ll be my girlfriend for the second time. How is this possible?”
I talked and laughed and made fun of Siyoung.
“Now, are you going to keep your promise?
I giggled and teased, but gradually stopped laughing.
“Siyoung-ah..? Sorry.. I was joking..”
Si-yeong laughed at her until she stopped laughing, and she burst into tears as if she were about to cry.
“It’s a joke, a joke… I won’t give you my pocket money, sorry.”
“Oppa, are you serious? You asked me to be your girlfriend?”
“No, I’m kidding. I’m sorry.”
“No, be honest, are you serious?”
“No.. I just said it as a joke because I thought it would be nice to have a girlfriend like you.”
I sensed being fucked.
If my parents knew, they wouldn’t let me go.
“If oppa is doing this because of my body, tell me, since it’s oppa, I’ll do it once”
“What are you talking about, Siyoung?”
“Oppa, you see my breasts often, I know. Or do you want to touch it? Come on, touch it.”
Siyoung lifted her tee and pushed her chest in.
“Siyoung-ah. Not really. Of course, I’ve seen your breasts grow. I’m sorry about that. I apologize. But it’s because I like your personality. To be honest, he’s my younger sister, but he’s pretty, kind, easy-going, and communicative. That’s why.”
I apologized sincerely and spoke up.
“I’m sorry about that”
“If it’s not because of my body, I’ll be your girlfriend.”
“Yes?”
Siyoung said that she would be my girlfriend.
“No, Siyoung, it’s a joke!”
“I thought it would be nice if my brother was my boyfriend too.
Siyoung was sincere.
“Then… Will you grant me two wishes?”
“Yeah, I’ll listen. Wait two months…”
So I waited two months.
In the meantime, we were bickering as usual, and if there is one thing that has changed, Siyoung has been working out. In two months, I lost 4 kg, and I became very pretty.
“Come on, oppa, it’s next year.”
“Yes”
We watched the countdown news on TV, and the 10 second count started.
10, 9, 8… 3, 2, 1 With a ding, Siyoung kissed me.
I am now an adult.
Siyoung worked out for two months and she tenaciously lost weight and made her abs into an 11 figure. She’s not perfect, but she made it to me to be a prettier girlfriend.
Siyoung came over to my legs sitting on her couch, sat down and kissed me, then took her clothes off and took my hand and brought it to her chest.
“Siyoung?”
“You’re girlfriends now, because lovers do everything.”
I touched and sucked Siyoung’s breasts like that.
It was her voluptuous, lustful breasts.
I wrapped my arms around Siyoung’s waist and kissed her while touching her slim waist and her big breasts.
“Brother, do you have to look at me for the rest of your life?
“Let’s do as headquarters, don’t look away either. Both of you will die.”
I kissed Siyoung and caressed her breasts, and the day ended just like that.
When Si-young was ready, she thought about having sex, and Si-young knew that and hugged me.
“I love you brother..”
“I love you too, Siyoung.”
And from that day on, Siyoung and I slept in the same room and washed together.
Siyoung opened her heart and started sucking her cock.
Every day after that, I ejaculated in Siyoung’s mouth, and Siyoung swallowed my semen.
And without having sex yet, he put her cock between Si-young’s breasts and had pseudo-sex.
“I love that her own breasts are really soft and big.”
“I’m sorry baby.. She wants to have sex with her..”
“It’s okay, I’ll wait anytime because I love you right now”
I haven’t had sex in over a year.
Instead, Siyoung sucked my cock every day and sucked her cock with her breasts.
And the day when Si-yeong turned 21 and became a coming-of-age day.
“Brother.. Have you waited for a long time? I endured it to do it today..”
“No, Siyoung’s first brother will take it.”
So I inserted her cock into Siyoung’s cunt.
“Ahhh!! Ohhhhh”
I pushed her cock as gently as I could and kissed Siyoung’s neck.
“Huh~♡ Haa♡ Heuhhh.. Heehee~♡”
Then, while sucking Siyoung’s breasts, he shook her waist.
Siyoung’s cunt was bleeding, and it was the first time for me too.
Tall, big breasts, and the 11-figure abs and lean thighs that I made by exercising until now for me. And even the muscles of the peach hips and back.
I felt that she truly loved me, and I also took care of her health for Siyoung and changed it to a style that Siyoung likes.
I put Siyoung on her stomach in a frog position, grabbed her legs, and fucked her cock.
Siyoung’s cunt was tight, and I gently but hard fucked her cock.
Seen from above, Si-yeong’s breasts were pressed against the bed and protruded to the side of her, and her breasts were compressed as if they were about to explode.
I massaged Siyoung’s breasts and fucked her cock.
“Honey. I’ll wrap it inside..”
Siyoung let out a moan from her and nodded her head, and I ejaculated inside Siyoung’s cunt.
Siyoung took a deep breath as my semen entered her, and she held on to the blanket as she accepted my semen.
Then I pulled out my cock, turned Siyoung over, and put her cock back into her cunt.
Siyoung hugged me and I hugged Siyoung.
“Brother.. I love you.. Now don’t throw me away just because you were with me”
“I’ll be by your side forever, don’t worry”
I ejaculated in Siyoung’s pussy like that.
And from that day on, we enjoyed sex every day, and I ejaculated on Siyoung’s pussy.
And we made memories while dating, and Siyoung became pregnant.
“Oppa!!!! Two lines!!! Two lines came out!!!”
“Now take care of yourself, rest at home, and do prenatal education. Keep our children healthy!”
“Yes! Honey!”
