I Was Reincarnated as a Creepy Fat Guy, Then Trained Myself Without Sleep. And Then, for Some Reason, the Heroines Start Approaching Me - Chapter 40: The Naughty Child

Hayama Residence

Suppressing the escalating excitement, I arrived at her and that guy’s house. When I rang the bell, a silly voice chirped, “Coming~” and the front door opened.

“Itsuki-chi!”

Her slightly dampened blonde hair fluttered, revealing emerald eyes reflecting my presence. She wore a white bra top and short black shorts.

Overall, her outfit was revealing, showcasing healthy, lightly tanned skin. Her legs had a gloss, well-toned thighs, and a strikingly exposed midriff hinted through the bra top. Despite being smaller than Kanna, her bust was mismatched with her slender waist. I knew that marshmallow-like sensation well.

For a high schooler, I thought she possessed something quite remarkable.

Seemingly fresh out of the bath, like myself before leaving home.

As I observed her figure, Marin, with a slight smirk, spoke up.

“Come in.”

“Yeah, I’ll intrude a bit.”

Marin’s Room

After handing over Hayama’s clothes, I was guided to Marin’s room, engaging in trivial chat until the delivery arrived.

Once the food arrived, we moved to the kitchen table.

And it was mealtime.

“You and Manabu have changed so much, even the other maids were surprised after you left! It was really something!”

“That much?”

“Yeah, really! Really! And lately, you haven’t been coming around much, so I’ve been worried.”

“That’s not good. With gym and stuff…”

“I know~♫”

Thanks to Marin, we got pizza and drinks at a bargain. So, dressed in my school uniform and Marin in her roomwear, we chatted while munching on pizza.

“By the way, I was surprised. I never expected Kanna-chan to be in the same class.”

“It was a shock for me too, knowing you’re Hayama’s sister.”

“Kanna-chan, Hayama, and you in the same class—totally destiny!”

“Yeah, it’s fate.”

“Are you close with big bro?”

She questioned me while sipping from a paper cup with soda.

I glanced up at the ceiling, pondered a bit, then responded.

“No, not really.”

“I knew it.”

“Huh?”

With a meaningful expression, Marin nodded, prompting me to continue.

“It’s hard to imagine big bro being friendly with you.”

“Really?”

“Yeah, he’s childish.”

“Hmm…”

“What’s that reaction?”

Perhaps she was bothered by my giggling as I recalled Hayama’s words and actions, Marin put her hands on the table and stared at me. Thanks to her, I could see her breasts in full view.

My eyes momentarily fell on the huge mass encased in her bra, but I looked at her face again and responded.

“It’s nothing.”

“It’s not nothing. I bet my brother’s been boasting about his mixers with girls from other schools, huh?”

“Pffft!”

“Hit the mark, huh?”

Marin chuckled while poking my chest with her index finger, clearly amused. Unconsciously, I tensed my chest, feeling the sensation of her slender fingers. Each time I experienced it, memories of the recent events resurfaced

And before me stood…

Blushing cheeks and a seductive expression.

Then she paused and spoke up.

Then, the girl in front of me,

With a seductive expression, her cheeks flushed, and the corners of her mouth lifted.

Soon, she paused and spoke,

“That’s why, maybe big bro needs Kanna-chan.”

“Huh!”

I widened my eyes and stared at Marin.

Just by hearing Marin’s words, I felt a shock as if I had been hit on the head with a blunt object

“Ah, I’m so full!! What about you, Itsuki-chii? You can finish it all if you want.”

“N-no, I’m good too. Thanks for the meal.”

“Okay then, shall we go wash our hands together?”

“Ah, sure.”

Invited by Marin, I stood up and headed to the sink. After both of us washed our hands amicably, we passed through the door leading to the living room.

I thought we’d continue with the cleanup and then return to Marin’s room upstairs, but she suddenly stopped.

Then, she turned on her heels and stared at me

“Hey, Itsuki-chi.”

“What is it?”

“It’s about Kanna-chan.”

“…?”

“Big bro’s been targeting Kanna-chan all along.”

…”

I was aware of that. Recently, he hasn’t been too involved with Kanna, but in the erotic manga, he’s been eagerly eyeing her body. Of course, they’d never end up together; it would conclude with him, hypnotized by the overweight Kondo Itsuki, falling both physically and emotionally.

If I followed the story as is, there wouldn’t be any issue. But I’m not someone who would involve themselves in such a crime, so I sealed it without using the hypnosis app. As a result, the situation was unfolding in completely unpredictable ways.

Once again, it’s the same.

What choice should I make?

As I pondered, Marin caught my gaze with her clear emerald eyes and spoke again.

“He’s quite persistent. That’s why the more you get involved with Kanna-chan, the more you’ll be dragged into his troubles.”

“No, I think I’ll get dragged into troubles even by being involved with you. You, Hayama’s sister.”

But Marin, who couldn’t possibly know the circumstances I held, continued with an expression that seemed to test me.

“So, go out with me.”

“Huh?”

“Wouldn’t that be a win-win for both of us? Kanna-chan doesn’t matter.”

She proposed this to me. She offered a deal. Her gaze was sharp, like a snake targeting its prey, seeming like a tyrant who wouldn’t be satisfied unless she took something away.

“What do you gain from this?”

And when I asked, she, with an utterly softened expression, opened her mouth.

“Itsuki-chi….. you are totally my type, I’ll be able to experience a lot of things.”

“!!!!!”

I was caught off guard.

Marin was a high school girl, but she was also a heroine in an erotic manga.

Her intensity was incomparable to the women from my previous life

My hand started shaking. No, not just my hand. My whole body was trembling.

If it were back when I first reincarnated, I’d probably have fallen head over heels for this sweet temptation

However, things are different now.

There’s something she’s overlooking.

The bonds with my family, friends, Kanna’s friends, and the feelings Kanna gave me…

Those shouldn’t be invalidated by Marin’s words; they are precious and need nurturing.

That’s why, to Marin…

I earnestly confronted Marin, who continued to gaze at me as if testing.

She seemed bewildered, stepping back, but eventually, her back met the wall.

Determined not to let her escape, I pressed my left knee against her groin. And then, holding Marin’s head, into those lustrous lips, I…

I boldly slipped my tongue into her mouth.

After ending the kiss, I whispered my voice directly into her ear.

“Marin, you have no learning ability. Didn’t I say I’d play tricks on bad girls?”

“!!!!!!!!!!!”

Then, I lifted her up.

She just panted, offering no resistance, entrusting her body to me.

There was nothing to hinder me.

I walked towards her room.
