Gloomy Outside, Gal Inside ~Dealing with My Step-Sister Isn't Easy~ - Chapter 08: My sister... my sister... uuuaaaaah!!

Chapter 08: My sister… my sister… uuuaaaaah!!

“I’m back…Ah!”

The man who returned home was greeted by the sight of his defenseless sleeping sister.

She was sleeping while still holding her smartphone, placing it on her stomach.

“Suu… suu…”

The sound of her regular breathing can be heard as her chest rises and falls.

With her voluptuous body that naturally arouses a man’s desires, the man returning from school involuntarily swallowed his saliva.

“…Damn it, she’s too erotic!”

She is a sister who attracts impure emotions from countless men even outside.

Although the man never harbored such feelings toward his sister as a brother, seeing his sister display such vulnerability while emitting an inviting atmosphere… an emotion that should never dwell in a man’s heart began to arise.

“…Is it okay if I just…”

Saying that, the man approached his sister.

Their relationship as brother and sister was not bad at all… one could even say it was good.

They not only exchanged light banter, but in the past, it was normal for them to take baths together… However, as time passed, as expected, such actions ceased to exist.

“We were both just kids back then… it’s truly amazing.”

Because he had known her since they were young, his sister’s growth was extraordinary.

The man slowly approached his sister, gently sat down, and stared at her sleeping face.

Not only did she have a bewitching figure, but her facial features were also very well-defined and she was considered cute and beautiful.

Her mouth that spouts cheeky words when she speaks, and her almond-shaped eyelashes… all of them are just parts that bring her sister’s beauty closer to perfection.

“…Alright.”

At this point, there was no choice but to go through with it. The man had made up his mind.

He convinced himself that it was her fault for sleeping so defenselessly, and that it was wrong for her, even as his sister, to be so provocative. 

From the moment her body began to show feminine curves, his sister had been flaunting her good looks. He had been tormented by her actions, and now, the man reached out as if to relieve himself of that torment.

“… Ohh.”

For the first time… for the first time, he touched his sister’s chest with his own will and his own hands.

Even through the fabric, he felt the astonishing softness. With a little pressure, his fingers delved into the soft flesh…

“Mmm…”

His sleeping sister wriggled her body in a teasing manner.

Her face seemed to be slightly flushed, but the man was already too captivated by the overwhelming elasticity to even notice.

“…Amazing.”

After touching her for a while, the man must have reached his limit. To release his own desires, he loosened his belt… and then—

“Hmm. It’s still good, huh?”

Since it was a rare quiet moment, I had to make good use of it. That’s how I immersed myself in reading manga in my room.

The manga I was reading, of course, was an erotic manga featuring a sister that shattered my sexual preferences. It’s already a big hit, with seven volumes already released–although I’ve read up to the seventh volume, I decided to start reading from the first volume again as a fresh start.

“Why is it so erotic and interesting?… There’s definitely erotic content, and it’s incredibly exciting. But what’s really precious is the romantic relationship between a brother and sister… Of course, there are erotic aspects to it, but the sister’s feelings are just so cute.”

Some people may not be able to accept the fact that the sister in this work is promiscuous, and there may also be people who can’t accept the brother who loves such a sister. 

However, this manga is purely about love, and it only depicts the romantic relationship between a brother and sister… and that’s what’s great about it! That’s what makes it amazing!

~Meow…~

“Oh, Cocoa, do you want to see too?”

Cocoa, who was curled up sleeping next to me, was looking at the manga.

Today is a substitute holiday, so Mom and Dad are busy preparing to go out, and Miu is studying because she has a quiz.

~Meow~… Meow!~

“Yeah, yeah, I got it.”

Cocoa meowed as if asking to see the next page.

If Cocoa, the cat, had a thought process similar to humans, I’m sure she wouldn’t approve of my hobby… after all, she’s a female cat.

We read the manga together for a while, but Cocoa quickly got bored and stared at me.

“Haha, yeah, that’s right. Dad and Mom aren’t here, and Miu is studying, so I’m the only one Cocoa can bother.”

~Meow!~

In other words, it means that Cocoa wants to play when she stares at you like that.

I closed the manga, opened my arms, and Cocoa jumped into my chest—then I pet her head and stroked her back, doing whatever Cocoa enjoys.

~Meow♪~

“Here? Is this spot good?”

Spending time playing with pets like this is truly great… because they provide so much healing that you stop caring about anything else, and it makes me genuinely grateful that I found this little one.

“It was about a year ago when I met Cocoa.”

Actually, our family didn’t meet Cocoa at a store.

On the way back from hanging out with friends, in the pouring rain, I found this little one hiding in a cardboard box.

I immediately knew it was a stray cat, but I also understood the challenges of having a pet.

So, as if apologizing, I once abandoned Cocoa, who was looking at me with a heartbreaking gaze.

“What’s wrong?”

“Did something happen?”

It was around the time of my parents’ recent remarriage when they noticed that I was enduring guilt for abandoning Cocoa, and that’s when I told them about Cocoa.

Honestly… I think it was good to talk about it.

Thanks to that, my parents said it was okay to have a pet, and Miu also said she wanted to have one together.

“Hey, Cocoa, do you think it was good that you came to this house?”

~Meow!~

Of course, words don’t really communicate… and yet, this little one meowed loudly.

When I receive such a response, I can’t help but feel happy and shower Cocoa with attention… I snapped out of it when I was scratched and apologized to Cocoa.

“I’m a little hungry. It’s a good time, so how about some snacks?”

I took Cocoa with me and went down to the living room… and there, I witnessed an incredibly timely scene.

“Suu… Suu…”

Miu, who was supposed to be studying in her room, was sleeping on the sofa.

It was a holiday, so her style had transformed into a gal-like appearance, and her usually straight hair was now in twin tails, maximizing the cuteness.

Her smartphone was placed on the desk, and her chest was rising and falling with her breath… Wait! Isn’t this the exact same scene as in that manga I just read!

“…Seriously, the accuracy of this recreation is too high!”

Of course, I’m speaking in a low voice so as not to wake her up.

Because of her short skirt, you can even see her panties from this angle… I’m sure Miu, who is sleeping, didn’t intend for that to happen, but if any other guy saw this, I have no idea what would happen. I’m being quite serious.

“…Nii…san…”

“!?”

For a moment, I thought Miu called me and got startled.

If this were the world of that manga, I would approach her without saying anything and do whatever I want… But this is reality, and furthermore, I don’t even know when my parents will come back—meaning, all I can do is watch.

“…What am I doing, seriously.”

After letting out a light sigh, I prepared some snacks for Cocoa.

While being healed by watching Cocoa eat vigorously, I also brought pieces of chocolate snacks to my mouth.

“…Hmm.”

However… even when I look at her like this again, Miu is truly seductive.

Lately, I’ve been thinking quite seriously, if I didn’t have a certain level of resistance from manga… How would I have looked at Miu?

Of course, I would feel excited, but would I have lost control and pounced on her…? Just thinking about it is terrifying, isn’t it?

“…No, that’s not it. No matter what, Miu is important to me.”

I told myself that, trying to convince myself.

~Meow!!~

“Hey, hey, Cocoa!”

Now then, while I was lost in thought, Cocoa finished eating the snacks and jumped on Miu.

The spot where Cocoa landed was right on Miu’s chest, and it must have felt incredibly bouncy to Cocoa.

Startled by the impact, Miu woke up and understood the situation when she saw Cocoa on top of her.

“Cocoa, huh… I actually thought Nii-san couldn’t resist and jumped on top of me.”

“Hey, what are you saying right after waking up?”

“I thought Nii-san couldn’t hold back and used my chest to contain his burning desires, freely doing as he pleased♪”

“Why are you saying such things!?”

Please stop saying such shameless things!

Looking at my sister who is grinning and saying these things without a hint of embarrassment… I can’t help but feel a little uneasy, wondering if there will ever come a day when I can surpass her, and if I can maintain my dignity as an older brother.

“And that’s why you’re an idiot!”

Even the TV that was on chimed in with a retort. I’m done with it.
