I Became the Younger Brother of the Villainess

But with my energy now coursing through me, I felt inexplicably delighted and chose to answer instead.

“I’m awake. Come in.”

The moment my reply left my lips, the door gently opened, and my sister entered. As always, she carried a tea set in her hands instead of relying on the ghoul maids. Carefully, she approached my bed.

Over the past month, every time my sister visited my room, it was as if this was the one space reserved just for the two of us. During these moments, no one—not even the ghouls who had lost their reasoning—was allowed inside.

Though I knew it was a form of affectionate obsession stemming from her care for her fragile younger sibling, I didn’t push her away. I liked her too. Of course, from her perspective, it was merely an expression of deep familial love and concern for her weakened brother. But for me, it might have been the moment that I started seeing her as a woman.

After all, spending hours together every day for an entire month, alone in a bedroom, dressed lightly and speaking intimately—what man wouldn’t eventually feel something?

From her perspective, she was probably just wearing something comfortable in front of her younger sibling.

“Where are you staring?”

The soft clink of porcelain echoed as my sister set the tea set down on the plush surface of my bed. Her question made me freeze. I couldn’t exactly admit that my eyes had been silently trailing the curve of her chest, the faint outline of her thighs, or the line of her waist. Shaking my head, I muttered a quick denial.

“Nowhere.”

“How silly.” She chuckled softly, brushing it off, and then skillfully prepared the tea and refreshments.

It was remarkable how much she had improved. A month ago, she’d been clumsy and awkward, clearly unused to such tasks. But after practicing diligently for weeks, she had grown quite natural at it.

“How about this? Your sister’s gotten pretty good at brewing tea, hasn’t she?”

These days, she even puffed her chest out a little, proud of her newfound skill. Apparently, among human nobles, young ladies who excelled at making tea or preparing snacks were quietly admired. Of course, they could just order servants to do it, but girls of that age often wanted to try their hand at making sweet treats.

For vampires like us, human food was little more than a luxury item, but if a vampire lady like her mastered the art of tea-making, it would surely make waves in society.

“I bet you’ll be really popular. Good for you,” I said, biting into one of the cookies she’d handed me. I savored the sweetness that lingered on my tongue before speaking again. With skills like hers, she’d definitely stand out among those who had never set foot in a kitchen.

It was meant as a compliment. Yet, for some reason, her gaze turned noticeably colder. With her pale skin and crimson eyes, the chill in her expression felt even sharper. To be honest, it was a little intimidating—her face alone exuded an icy aura.

What did I say wrong?

“…Do you not like the idea of me being popular?” she asked, her voice measured.

Unable to figure out the issue, I cautiously responded, “Is that really the problem?”

“Do you really not get it?” she sighed.

“No idea,” I admitted honestly.

She let out a small exhale, almost a resigned sigh, and leaned toward me. Sitting on the edge of my bed, she reached out and gently pinched my cheek. Her upper body tilted slightly closer, bringing us into an unexpectedly intimate proximity.

“I didn’t practice so I could get popular with other people. Do you get it now?”

Oh.

I see.

“So… you practiced for me, but my comment made it sound like you’d just share it with anyone else? That upset you?”

Was that it?

I didn’t think it was the right answer, but to my surprise, she gave me a playful smile and nodded.

“I don’t even have enough time to make things for you. Why would I waste it making things for others?”

What the hell. Why is my sister so sweet and adorable?

Honestly, this was stirring something in me. Having such a beautiful, kind sister treat me so warmly… it was enough to make me want to say, “Goo-goo, ga-ga, I’m your baby vampire.” Not that I’d ever say that out loud.

Her leaning posture only made things worse. The loose fit of her clothing revealed a glimpse of her chest, snugly held in place by her undergarments.

I wanted to touch her. My hands practically itched at the thought. On top of that, her proximity carried a faint, intoxicating scent. It was overwhelming. I could feel my body reacting, and I barely managed to suppress it by subtly manipulating the flow of my blood.

“Why aren’t you saying anything? Are you even listening to me?”

“I’m listening,” I replied quickly.

I wasn’t. She was definitely saying something, but my mind was too preoccupied to process it.

I wasn’t in my right mind. It felt like I was tipsy, like I’d had a drink and the buzz had gone to my head. My sister was saying something, probably, but instead of listening, I found myself blurting out random, contextless remarks.

When I offhandedly asked if we could hire a human maid, her expression turned cold for a moment, and that brief chill brought me back to my senses—if only temporarily.

But soon enough, I slipped back into that hazy, dreamlike state.

…

Come to think of it, am I the one being charmed right now?

The subtle, pleasant scent in the air, the sudden surge of desire, my hand twitching at the sight of her chest, aching to touch it—if this isn’t being charmed, then what is?

Snapping myself out of it, I forcefully expelled the charm’s lingering magic from my body.

As my mind cleared, so did my vision.

Before me stood my sister, her cheeks flushed a deep crimson. Her breathing came in slow, labored gasps. Beads of sweat glistened on her forehead, trailing down her dampened neck and collarbone. She looked, in every sense of the word, utterly disheveled—like someone lost in the throes of arousal.

“Ugh… uh… are… you… listening to… what… I’m… saying…?”

Just moments ago, she’d been scolding me for not paying attention. Now her voice was reduced to breathy murmurs, barely coherent. It didn’t take long for me to figure out what had happened: while I’d been caught under her charm, she’d succumbed to mine.

With neither of us resisting the other’s allure, we’d ended up in this mutual state of enchantment. It wasn’t a one-sided domination where the stronger magic user overpowered the weaker one; we’d both fallen victim to each other’s charm simultaneously.

Her flushed face and trembling form were intensely provocative. Even though I’d already shaken off the charm, I couldn’t help but feel aroused all over again. I tried, but failed, to suppress the reaction. Before I knew it, I was fully hard. Given her dazed state, it didn’t feel necessary to hold back anymore.

Still, acting on it right now would definitely be premature. Suppressing my urges, I scooped her up in my arms.

“W-What… are… you… doing…?” she stammered, wriggling weakly in my hold.

As her legs kicked, her smooth, slender thighs were exposed. Unable to resist, I gave them a firm squeeze.

“Hiiiiiik!”

A sharp, high-pitched squeal escaped her lips, but I ignored it. Carrying her out of the room, I handed her over to the waiting ghoul maid stationed just outside.

Phew.

I almost crossed a line there.

Still, this should have earned me some points, right?

Why didn’t he take me?

I used such a strong charm…
