Reincarnated as the Sidekick in a Harem Game ～Chaos Unfolded When I Helped the Losing Heroines After the Protagonist Found His Happy Ending～ - Chapter 25: Big Sister is Also Obsessed

Chapter 25: Big Sister is Also Obsessed

One day on my way to school, I, Charao Shibuya, was abducted by a mysterious man. Just when I feared I would be abandoned in the East China Sea, my stepsister, Aane Shibuya, appeared before me.

“Ah, Big Sis… it’s been a while.”

I was inside a black Mercedes. Seated next to me was a beautiful girl with silver hair.

Beautiful blue eyes like sapphires. Long, lustrous silver hair. And breasts as large as those of Mamako-shi, neither inferior nor superior.

“… Cha… It’s been a long time.”

“Cha” is my nickname. Aane-shi hugs me tightly. She places my head on her chest.

“Um… excuse me… but your chest…”

“?”

Aane-shi looked at me with a curious expression.

“…Are you feeling it?”

“Ah, yes… but, however, for a woman to engage in such, such indecent behavior…”

Aane-shi was an exceptional beauty. If someone saw us like this, I would surely be beaten up out of jealousy. I wanted her to let go, but…

“…There’s nothing indecent about flirting with your boyfriend, is there?”

“No, boyfriend… Big Sis, I’m not… like that…”

“… Cha is mine. I am Cha’s. I missed you…”

Aane-shi hugged me tightly again. My sister had always been a bit of an oddball.

“… Cha, didn’t you miss me?”

She looked down at me with sad eyes. That wasn’t the case.

“I missed you, Big Sis.”

“…Really ♡”

Aane-shi drew her face close to mine and kissed my lips lightly.

“…I missed you too. I’ve wanted to see you for so long.”

Her kisses were soft and pecking, as if nibbling gently. It wasn’t something new. Ever since I was taken in, she has been excessively affectionate, treating such interactions as perfectly normal.

“Ah, Big Sis… kissing, that’s a bit…”

“Chu ♡, nchu ♡, chu… ♡, chuu… ♡.”

Aane-shi’s kisses were relentless. My face was sticky with saliva, but there was no discomfort. It was sweet… as if her saliva had a flavor that could deceive my senses. And they were passionate kisses. Her composed face was right next to me, the cool impression she usually gave off contrasted with the passion of her kisses, making my head spin…

No, this isn’t right! We can’t go on! I’ll be persuaded!

“B-Big Sis! Please, let go!”

I pushed Aane-shi away, but with too much force, I ended up pinning her down on the sofa. Her silver hair fanned out over the cushions. Beneath the thin dress, her soft, plump breasts sagged slightly under gravity.

“I… I’m sorry…”

“… Mm. It’s okay. Come, Cha.”

“What do you mean, it’s okay?”

“…Aren’t we going to have sex? I want you to hold me. Rather, take me. I want my first time to be with you.”

Her words were shockingly direct. Aane-shi has always been a bit peculiar. She’s always had this attitude.

“Big Sis… a lady shouldn’t use such language.”

“…Strange?”

“It’s strange.”

“…You’re also strange, Cha. The way you speak is odd.”

Aane-shi is a heroine who appears in the main story as well. Last year, she was compelled to be a student. But now, free from the shackles of compulsion, she has returned to her original profession.

Yes, she is an internationally renowned pianist, currently active in her career.

But that aside.

“…Your way of talking may be odd, Cha, but you’re still Cha. My beloved Cha. So… will you do it? Will you feel good with my body?”

Aane Shibuya, even in the main story, has this slightly odd and erotic older sister character. The affection she’s showing me now, she once directed at Minato for a time.

But before the main story began, she was a huge brocon, always wanting to kiss and hug. Whether there was romantic affection between a man and a woman… I’m not sure. But…

“Big Sis. That, I cannot do. We are siblings.”

I steadfastly maintain my stance as her brother. Involving myself with the heroines could potentially destroy their lives. The power I possess… it’s imbued with such a bewitching force.

I love all the heroines. And because I love them, I don’t want to twist their fates or personalities with this power of mine. I want them to be happy just as they are.

“…? Is there something… strange about siblings having sex?”

…Contrary to my feelings, Aane-shi was all for moving forward without hesitation.

“…But isn’t sex something you do with someone you love? So what’s wrong with that? I truly love you, Cha. You love me too, right?”

“That is… certainly, I do love you. But, Big Sis, that loving is the love of family…”

“…What Cha is saying is too complex for me to understand, but…”

Aane-shi abruptly sat up and pushed me down.

“…This part of you is honest, isn’t it? ♡”

Uhhh… She gently began to fondle my gentleman’s area (※ euphemism).

“B-Big Sis!? You must not do that!”

“…Fufu♡ What do you mean by must not?”

“N-No… You mustn’t touch that!  Ahh! Big Sis! Noo!”

★ Aane’s Perspective

I am Aane Shibuya. The name doesn’t matter. What matters is that I’m the beloved older sister of Cha. That’s all that’s important.

I’m a pianist. Apparently, I have talent. I don’t need such talent. But the people around me won’t leave me alone.

One day, Mom brought home a piano teacher. I played haphazardly. I wanted to quickly go and play with Cha. Cha is dear to me. I really, really, love him so much.

I want to be by your side forever. Cha is my world. Cha is my universe. The person who is so precious to me, someone I never want to let go of.

But everything changed after I performed for the piano teacher. Before I knew it, I was being called a prodigy. I didn’t care about that at all.

But then I thought about it. I need money to support Cha.

My dream is a modest one.

I want to buy a house with a bunker and live there with Cha forever.

Bunkers are quite expensive. Not something one can buy alone. But apparently, my piano playing can generate money. So I decided to work hard as a pianist.

I’ll work hard to earn money and support Cha. In a house with a bunker, just the two of us will spend our time together until we decay. Ufufu♡

…Ah, I might have gone a bit strange for a while. But now, I’m back to normal. I can only see Cha. I love Cha. Cha. Love. Love you…♡ Love you so much…♡

I want to lock Cha up ♡ I want Cha all to myself ♡ I want everything of Cha’s ♡ Cha’s body, Cha’s essence, Cha’s children, I want to make them all mine ♡.

Cha’s heart and body, I want it all ♡ Ah, love… love…♡ I love you so much… Cha ♡
