Betraying My Perfect and Beautiful Childhood Fiancée, I Fell in Love With My Devilish and Naughty Older Sister - Chapter 15 - I Love Nii-san

Chapter 15 – I Love Nii-san

Chiharu-senpai smiled with satisfaction when she heard Shiho’s words.

“Cute! But we’ll have to punish you more for being such a flirt, won’t we?”

“Eh, you said if I admitted it, you’d let me go… Hyahh.”

Chiharu-senpai became more aggressive in teasing Shiho.

I finally tried to stop Chiharu-senpai.

“C-Chiharu-senpai. Please stop.”

“Why?”

“Shiho is my younger sister. If you do anything too terrible, I will get angry even if it’s Chiharu-senpai.”

At my words, Chiharu-senpai mumbled “hmm” and looked at me with stern eyes.

“I envy Shiho-chan.”

“Huh?”

“Because Shiho-chan is seen as a sibling by Hayato-kun. But he doesn’t accept me as his sister.”

“I-Is that what you mean…?”

“It’s important to me. I’m going to be your family too, remember?”

Now that she said it again, it’s true. No matter how suspicious her identity is, it’s a fact that Chiharu-senpai will become my sister as an adopted daughter of the Hashiro family.

“I understand. Chiharu… Nee-san.”

Chiharu-senpai gave a happy response.

“Well said. But I prefer ‘Onee-chan.'”

“As expected, that’s embarrassing, so please spare me.”

“Well, I’ll let you off with that for now.”

Chiharu-senpai let go of Shiho.

When Shiho was released, she cried “Huuu~” and hugged me.

“S-Shiho!?”

“Nii-san…! I can’t be a bride anymore…”

“N-No, that’s not true…?”

“I was humiliated like that…”

Shiho said while puffing up her cheeks.

Shiho’s soft parts were pressed against me because I was being held tightly from the front.

She was dressed in a very revealing outfit to begin with, and I was totally dazzled… She’s my stepsister, but I see her completely as the opposite sex.

Shiho looked up at me sweetly.

“H-Hey. Nii-san. Since I can’t marry… Will you make me your mistress?”

“Eh!? S-Shiho!? Even if it’s just a joke, you shouldn’t say that…”

“I’m serious.”

Saying that, Shiho rubbed her soft cheek against my breastplate. I was startled by her boldness.

What is really going on?

Shiho’s face was as red as ever, but it seemed redder than simply being shy. And besides a girl’s characteristic sweet scent, there was a slight smell of…alcohol.

“I think Shiho-chan mistakenly drank the alcohol that was in the dining hall earlier.”

Chiharu-senpai interrupted with a chuckle from the side.

S-So that’s what happened!!

“Didn’t I say it earlier? I dressed up like this because I wanted Nii-san to do something naughty to me.”

“B-But…”

“I know Nii-san cares for me as a younger sister. But I want Nii-san to touch me in a different way.”

Shiho’s arms were wrapped around my neck. I could feel my body temperature rise as I was in close contact with her from the front.

Fufu, Shiho giggled.

“Nii-san, are you embarrassed…?”

“O-Of course I am.”

“Nii-san belongs to Aika-san, but for now, he belongs to me.”

Shiho giggled once again.

“I don’t really belong to Aika.”

“You can’t say that, Nii-san. But… If Aika-san ever betrays Nii-san, I will comfort him on her behalf.”

“Shiho…”

“I love Nii-san. Even if I’m second, I want to be with Nii-san.”

Shiho whispered to my ear.
