My sister is a villain in an eroge?! (hiatus)

Nathaniel POV:

My mother was a beautiful woman, it is not mentioned much in the book, but now that she is literally in front of me, I can say that I have not seen such a beautiful woman in all my life. Even Novem, my little assassin, cannot compare to her, Lilia's figure is in another dimension, and her mature charm has finished settling, thus giving an irresistible combination for any man.

First, my mother went to her room to rest from the exhausting trip. I didn't show it on my face at the time, but a fucking airship landed in our yard; that was surreal. 

Our footsteps echoed as we made our way to the dining room. I wanted my mother to eat her favourite dish; surely she would earn some points for that. The only bad thing was that I had no idea what my mother's favourite dish was. We asked a short, chubby maid who told us that our mother especially liked a meat dish, but she wasn't sure; It was worth a try, the consequences of failure were close to zero.

"(Do you think that's her favorite dish?)" My little sister asked as she walked beside me.

"(I'm 70% sure)" I said as I turned a corner.

"(Let's hope luck is on our side)" She prayed as she followed me.

Before we had even reached the dining room, the smell of food filled the air. We looked at each other with a smile and then opened the massive double doors to the dining room. Maids and waiters were frantically running around and the sound of meat being cooked pierced the kitchen walls.

" You're working hard!" cheered my little sister acting childishly with a smile.

When we arrived, everyone stopped running to serve us.

"Do you need anything?" asked an earnest and bespectacled maid.

"Nothing, I just wanted everything to go perfect, I see you guys are working hard." I nodded, smiling, trying to look like just a curious kid.

After a while, we sat at the table, waiting for my mother to arrive in the dining room. I perused the store in the meantime deliberating whether to buy the skill I thought was the most versatile in terms of use when it came to conquering heroines.

[Touch of pleasure:

Description: The host can transmit pleasure through any part of their body if it comes into contact with another person's bare skin.

Price: 4,000 fate points 3,500 affection points]

In the end, I decided to buy it. It would be advantageous in the near future. As soon as I bought the skill, a notification resounded in our ears.

[Ding!...]

[Congratulations to host 1 for obtaining the achievement 'First purchase in the store']...]

[Generating rewards...]

A roulette wheel appeared in front of my eyes and started spinning, I confirmed by eye contact with Charlotte and she nodded, so we waited for our rewards to finish generating.

[Congratulations! Host 1 has won the skill 'Hand-to-hand combat {intermediate}'].

I nodded my head, and I could feel various knowledge flooding my mind, giving me a headache, having a child's mind was quite problematic. The pain progressed to the point where I had to hold my forehead with my hand while gritting my teeth. My little sister was no better; she moaned slightly while resting her head against the table. Just when a maid was rushing to ask anything, the system spoke.

[Stabilizing the mind of the hosts...]

[Intervening the process...]

[Reconstruct…5%...35%...76%...99%...]

The pain subsided to a tolerable degree just as a delicate hand rested on my back and a maid whispered in my ear.

"Are you all right, young master?" She asked with slight concern in her voice, I turned my head over my shoulder, and a maid with brown hair and grey eyes looked me in the face, scrutinizing my expression.

"I'm fine" I said, smiling slightly.

"(Are you okay, Charlotte?)." I questioned worriedly, watching my little sister, who had a frown on her delicate eyebrows.

"(I'm better, it hurt like shit)."

"(What did you get?) "I inquired blinking heavily, trying to diminish the remnants of the pain.

"(Right! I got, 'Bow handling {intermediate}' how about you, big brother?)"

"(Hand-to-hand combat {intermediate})" I replied.

"(eh... didn't we already know how to fight, big brother? Isn't it a useless skill?)." my little sister asked, pursing her lips.

"(Not quite, with this I have more knowledge than just boxing and self-defense)" I replied, reassuring my little sister, we continued talking until a rustling, and slight squeaking noise got our attention.

The dining room's double doors opened inward, and a beautiful woman with black hair that fell to her slender waist like a waterfall entered with a slight smile on her red lips. As soon as her fiery eyes landed on us, a beautiful toothy smile formed on her face.

At last, Lilia had arrived at the dining room, wearing a looser but dignified dress. That dress could not suppress her mature figure and charm; her huge breasts swayed up and down with every step, and her curvaceous figure, barely concealed by her clothing, made her irresistible. She sat in the most important seat and gave us a nostalgic smile.

"How long has it been since we all got together for a meal?" She asked rhetorically, then sniffed the air, and her eyes lit up. "The chefs prepared Boeuf Bourguignon?"

"Yes, mom, I knew it was your favorite that's why we ordered them to serve it today" I nodded with a smile.  I was cheeky, but it didn't matter; the worst that could happen was that it wasn't her favourite dish.

+500 affection points.

+50 fate points.

When the food was brought, we all devoured the dish, but Charlotte and I tried to be as prim and proper as possible, following what little noble etiquette we knew, but our inexperience was evident compared to our mother. Her every movement brimmed with style and decorum, she looked like a painting, and I couldn't help but admire her beauty. Her slender, milk-white arms moved gracefully as she cut the meat, her eyes narrowed in bliss as she took a bite, and it wasn't until Charlotte pinched me under the table that I continued with my meal.

+100 affection points.

"(It seems that the main characters give more points than a normal person)" I noted as system notifications filled my ears.

"(You're right)" She acknowledged, although our meal was silent, we had confirmed several things.

The meal ended quickly. Lilia stood up, thanking us for ordering her favourite dish. Her friendly smile only widened when we acted happily. After that, she left the dining room to go to her office. Later I would go there and start working on it; I had some long term plans that could work. It all depended on her personality.

"(Maybe you should try to buy a spell to make her dream in a lewd way about you)" My little sister proposed, but I shook my head.

"(It's too early, I don't even know if this body can have an erection, besides she is a level 3 purity, maybe she can detect the spell, all our work would be in vain if she knows I'm manipulating her)."

"(Well, there is a way to confirm the first question)" My sister said suggestively, raising her eyebrows repeatedly.

"(Don't be horny)" I shook my head and ignored Charlotte's blatant flirting.

"Novem, I need your help here, I don't think I'm doing it right" Later that day, while purifying my magic in the training area, I called Novem.

A couple of days ago, I had learned to purify my magic power myself, so Novem simply trained us in exercises to strengthen our bodies. However, since I had purchased the skill 'Touch of Pleasure' Novem seemed like a good guinea pig to test how effective it could be.

She said nothing and sat on my back, spreading her legs, leaving her crotch right on my back as we pressed our bodies together. Her combat suit left almost no skin exposed, so using the skill would be relatively more complex. But I could transmit pleasure through her hands expose.

Novem, oblivious to my considerations, placed her hands on my chest as I directed my magic towards my forearm. Just as she followed my magical flow and touched my bare forearm, I activated the skill.

"Hiiii!" Novem jumped out of her place due to the sudden sensation. I could control the pleasure, but I only used its fullest capacity as a test.

"What's up, Novem, is everything okay?" I asked, turning my head over my shoulders and giving her a genuinely 'worried' look.

Novem had a slight blush on her face and looked confused at my forearm and her right hand with her black eyes, but then shook her head and took a deep breath, her bulging chest rising with her breathing.

"It's nothing, I just felt something strange" She relaxed and returned to her normal expression.

She again tried to feel my magic, and this time when she touched my forearm, I only send minimal pleasure. Novem stopped her movements slightly but quickly kept trying to detect errors in my magic flow. Since she didn't have much reaction, I tried to increase the pleasure a little; this time, she lightly squeezed her legs around my waist with a slight blush on her face.

I lowered the pleasure, and she relaxed, but now she was wary of touching my forearm, her breathing was somewhat agitated, and a slight blush spread across her usually stoic face. The sweat on her body made some strands of black hair stick to her forehead. She looked as if she was sick, so I took this opportunity.

"Are you okay?" I said, looking at her face, which looked confused. I extended my hand to her forehead, and she jumped slightly, but this time she didn't receive pleasure or anything like that when I touched her.

"You have a little fever, you should go rest, you are always working hard" I smiled, and she saw my sincere eyes, without any malice. I immediately heard two notifications from the system.

+2,000 affection points.

+3,000 fate points.

[Novem:

Love: 5% >>> 7% Obligatory Respect (Slightly disappointed in your previous attitude, but has noticed that you are now changing)]

"Yes, thank you, young master" She nodded and as if fleeing, she blended into the shadows.

"(Okay, I will go visit our mother, I will inform you the progress and plan for tomorrow when I get to your room)" I informed my sister through telepathy.

I had told her to say she wasn't feeling well so I could be alone with Novem.

"(Understood, big brother)" She spoke, and I could hear the jealousy through telepathy. I sighed as I walked out of the training area.
