Miko and Haru is brother and sister.

Miko is the younger sister while Haru is the older brother.

They don't have parents. They live in a single apartment.

Haru love her sister very much, he's always spoiling her by making her do nothing at home but read her favorite books and play some games.

They're still both young. Haru is just 17 years old and Miko is 14 years old.

One night, while Haru is sleeping we can see Miko kissing him.

Haru isn't aware of this but her sister loves him very much too but she loves him as an opposite sex, not as a brother.

While she was kissing him. Haru woke up.

And when he saw what his sister did to him, he got mad.

"What are you doing?" He asked angrily while touching his lips.

"I'm sorry for kissing you, I love you." Said Miko with a sad face.

After that, Miko started crying non-stop.

She repeatedly said that she loves her brother and want to do romantic things with him.

Haru pitied her sister and then he hugged her tightly and said "I'm sorry. Miko."

And that made her stop crying.

But she kept saying that she loves her brother and wants to kiss him.

Haru's heart started pounding. He doesn't understand what's happening to her sister.

Her sister kept telling him that she likes him.

"Do you really love me, Miko?" He asked her sister.

"Yes. Ever since our parents passed away. I've always loved you. I want to kiss you, hug you and have sex with you."

 She said with tears falling from her eyes.

Haru's expression changed.

He wanted to kiss her so much. But he didn't. He thought it was wrong to kiss his little sister like that.

He couldn't say no though.

He had never kissed anyone before.

He knew it's wrong but...

"Miko, let's kiss." He said.

"Really? You'll kiss me?" She asked hopefully.

"Of course!" Said Haru smiling.

Then she gave him a peck on his lips.

Miko kept kissing him. It felt so nice but his brain told him it's wrong but he didn't dislike the feeling.

"Haru.." Said Miko while looking at her brother with passionate eyes.

Haru can't look at her as a little sister anymore. He wants to kiss her and fuck her.

She pushed Miko to the bed and groped her undeveloped breast.

"I love it when you're touching my breast." Said Miko.

When Haru heard this he got excited and started to explore her body.

Soon they were naked and lying on their sides.

Miko started to caress Haru's bare back.

"Haru, touch me more gently!" Said Miko.

Haru did what she asked.

He touched every inch of her body. He touched her breasts, her hips and her vagina.

He then placed kisses on her soft skin. Then he took her panties and slowly pulled them down.

He could feel her wetness. He licked it all.

He then put his head between her legs and started to suck her clit.

His tongue glided over her folds.

She moaned loudly. Her hands ran through his hair.

The feeling of being taken care of and pampered overwhelmed her.

As the feeling became stronger and stronger, Miko came hard and fast.

Haru felt her warm liquid.

"Brother!"

Haru pulled out his massive cock. He's exploding to try her sister's pussy.

He inserted it and rapidly pounded her sister's virginity.

"It feels so good Miko! Let's do this everyday."

"Yes. Yes! Yes!! ahhh!" she shouted while moaning.

He hugged her brother tightly while his brother is senselessly fucking her.

In the end he ejaculated inside her and fell asleep.

That night he slept peacefully without having nightmares.

He dreamed about loving his sister.

He dreamed about how happy they would be together.

Haru woke up early.

He saw her sister lying next to him. He can't see her as a little sister anymore. He only see her as a girl she loves.

Haru can't stop himself and proceeded to kiss her sister.

While he was about to do that, her sister woke up and hugged him tightly.

They're both naked so the two felt horny instantly. 

Their morning was filled with moans and pleasure.

It was already 10 AM when the two finished having sex.

Miko cleaned herself up and both decided to take a shower together.

Once they're done showering, they went downstairs together and prepared breakfast.

"Brother. From now on, don't treat me as your little sister anymore. Treat me as your girlfriend, and from now on I'll stop treating you as my brother because you're my boyfriend now." said Miko while giving Haru a kiss on the cheek.

"Okay. I'll change my way of thinking from now on. Thank you for trusting me." said Haru while embracing his sister in a big hug.

"You don't have to thank me." said Miko while hugging Haru tight.
