Chapter 33 

I Want to Satisfy My Stepsister

“Make me forget what happened with Kanashizuku…? Yuzumi, aren’t you misunderstanding something? What happened between Kanashizuku and me was—”

“At this point, I don’t care about what happened between you and Kanashizuku. From now on, I’m going to satisfy you myself.”

…So that’s why she suddenly did something like this.

I had been fretting over whether feeding me or holding my hand counted as “a big deal,” but it seemed that Yuzumi was thinking far beyond that.

Yuzumi, as usual, had a vacant look in her eyes, yet her expression was one of ecstasy as she began to remove her uniform—but I firmly tried to explain what I suspected Yuzumi had misunderstood.

“Yuzumi, you’re misunderstanding. Kanashizuku and I haven’t done what you think we did.”

“I can’t believe your words, saying you haven’t been involved with a woman,” she replied.

Saying that, Yuzumi took off her blazer and then started undoing the buttons of her long-sleeved shirt—I stopped her hands.

“You said before that you don’t like using force like this. So let’s stop for now and talk calmly.”

“If you’ve done anything with another woman, I can’t just stand by… I want to satisfy you all by myself, right now.”

Previously, in a similar situation, she had said the same thing, and that day only, she had accepted being my little sister… but now, Yuzumi was so emotionally cornered that my words couldn’t reach her.

I was about to speak when I froze.

The reason was that Yuzumi had undone all the buttons of her long-sleeved shirt, revealing her underwear underneath… Even though she was still wearing the shirt, the open buttons exposed her mature black lingerie and a glimpse of her ample chest.

It was an overwhelmingly strong stimulus that made me freeze.

Amid that, Yuzumi blushed and leaned closer, speaking in a sweet voice:

“How is it, big brother? My body… it was hard to see when I had a towel in the bath, but it’s quite big, right? You don’t have to hold back just because I’m your sister. We’re not related by blood, and I really love you… if you nod, you can do whatever you want with me.”

—The reason I was frozen now wasn’t because Yuzumi’s body was attractive.

To be precise, it would be a lie to say her body wasn’t appealing—it was firm and her chest was ample—but the cause of my shock wasn’t her body itself—it was the fact that I had seen my stepsister in her underwear.

“Or are you going to insist again that we’re siblings and refuse to be honest with yourself and me?”

Surely, if we were true siblings, raised together and blood-related, seeing a little of a sister’s body wouldn’t shock me… And I should be able to treat Yuzumi as my sister—but here I was, shocked to see her in underwear. Why?

“Even if you won’t be honest, I’ll be honest for both of us,” she said.

Our only connection was being siblings… if we were blood-related, something like this wouldn’t be an issue, but being step-siblings without blood ties meant that seeing Yuzumi like this carried a certain meaning—and if meaning arises, then impurities enter our step-sibling relationship.

—If that happened, the bond between us would vanish.

Just thinking about it made my heart race with agitation and fear.

“Being honest means next, I have to take these off…”

I sat up, placing my hands on Yuzumi’s shoulders as she straddled me, and said:

“Yuzumi, please… let me remain your big brother forever.”

My voice trembled slightly as I spoke; the turmoil in my heart probably showed on my face as well.

And upon hearing that, Yuzumi—
