Chapter 174: The group chat ii

Is it okay for a student to wear something like this?"

Jokingly, I posed the question, and Yuna hesitated, her cheeks flushed red and her hands clasped tightly together.

"Well... I wanted to show my brother some sexy underwear. I’m sorry for using the coin on something like this."

"Don’t worry about it. It’s fine to use it for your sister’s underwear. But isn’t it a bit too flashy?"

To be honest, I didn’t mind it at all.

If you were to ask if it’s a suitable match, perhaps it might be a bit of a mismatch?

"Actually, I already... look like an academy student, so what’s the reason for buying something like this? The male clerk even said it’s more risqué than it appears."

"Where is that guy now?"

Yuna took the lead and grabbed me.

"Oh, big brother! Isolde took care of him for me! It’s fine!"

"Phew..."

In any case,

It’s not the kind of underwear a model academy student would typically purchase. She wouldn’t have normally owned something like this.

It’s solely for the purpose of showing it off to her brother, one hundred percent—something she wouldn’t have done otherwise.

"Doesn’t it suit me? Should I... get a refund?"

"No. I want to see Yuna’s lewd, mischievous side."

"..."

"Show me."

In broad daylight, with her brother inspecting the underwear she bought,

and even insisting that she should wear it and show him; she’s the perfect erotica game protagonist.

She’s living and breathing right here, right now.

"Can I wear pantyhose?"

"No. Bare skin. White high knee socks."

"..."

She even customizes on the spot!

Though slightly embarrassed, Yuna twisted her waist and agreed to her brother’s request.

"Yes, I’ll dress as you desire."

Such is the authority of my older brother.

"Shall we go home together? Have you finished shopping with Isolde?"

"Ah, I briefly went to the restroom. I’ll be out shortly."

"Oh, senior."

Isolde, who certainly isn’t a gentleman, walks out.

My attention is drawn to the abundant bosom of my younger sister’s friend, which rivals Yuna’s intensely curvaceous chest in her casual attire.

"Hello, Sol."

"Do you know what just happened?"

"What happened?"

"Yuna was approached by five suitors while walking around. All within a mere hour."

Those damned rascals...

They must have been targeting our Yuna’s firm derrière.

Quivering...

"I had quite a difficult time fending them all off."

"I’ll reward you with some coins."

I instantly donated 10 coins.

"Thank you~."

"Weren’t you approached as well? One would think you’d both be targeted."

"I was, but I refused their advances. Just because a man’s talent is crude doesn’t mean I’ll stoop to their level of vulgarity."

"I hadn’t considered that."

You, on the other hand, are steeped in victim mentality. That’s the issue.

"Oh, I’m sorry... I was up editing all night. Ugh... I’m a bit sensitive now."

"You worked hard."

With a swoosh, I naturally reached out to touch her. Sol placed her cheek in my hand and rubbed against it.

"Did you also stay up all night?"

"Just a bit. Why did Sol stay up so late and go shopping early in the morning?"

"Well, Yuna said she needed sexy lingerie to break your resolve, so she called me out."

"Sol, you!"

Yuna’s secret was inadvertently exposed.

Lingerie meant to shatter my resolve...

"You shouldn’t try to break my resolve like that. I don’t even have any coins."

"You don’t have any coins? You seemed happy when you received a lot of them."

"Not those coins."

As Yuna locked eyes with me, her cheeks flushed red.

What was she planning to accomplish by breaking my resolve? This strange younger sister of mine?

And even after I told her there were no more defense coins,.

"So, Isolde picked the sexy lingerie?"

"Yes. It’s really sexy and pretty, isn’t it?"

"..."

I’m not very familiar with the world of women’s lingerie.

"I mentioned that it might be a bit too flashy, my dear brother."

"Really? You’re so oblivious."

"...No... It’s just that it’s true."

"Or do you get more excited when your sister’s underwear looks more infantile?"

"Excited? Not at all!"

Just try wearing something like teddy bear underwear. It’ll be ripped right away.

"I don’t have that kind of criminal inclination. If anything, I’d prefer more striking underwear."

"That’s right, Yuna. You confirmed it with your own mouth, so it must be true, right?"

"Yep."

He seems to be embarrassed because the conversation keeps revolving around his underwear.

When he’s genuinely focused on his sexual desires,

Yuna becomes an erotic heroine who doesn’t even need sexy underwear. In this world, only **Mira** and I know that.

It’s called the "Hexagonal **Fleshlight**."

"I decided to wear... vulgar underwear... with white knee-high socks, on bare skin."

"What on earth are you making Yuna do?"

"In our family, there’s a tradition of gaining energy by looking at a sister’s underwear."

"Pervert..."

[**Mira**’s agreement +1]

... ...

How did I end up stuck in a world like this?

The perverse recognition stack, oblivious to human emotions, is infuriating.

"I wonder if it’s my girlfriend’s underwear."

"What are you wearing now?"

"You have keen eyes, senior."

*Tsk.*

"Anyway, enjoy your shopping. I’m going home."

"What were you doing hanging around here, anyway?"

"I’ve been working since yesterday. Now it’s time to go home and rest."

Isolde seemed slightly taken aback.

"No way, you tried so hard in the competition; did you really stay up all night? I’m worried..."

"Why didn’t you get some sleep instead of talking to others?"

"..."

She closes her mouth tightly, looking adorable as if she’s at a loss for words.

"See you at home, Yuna."

"Yes, oppa!"

"Sol, too."

I hugged Sol lightly and kissed her on the forehead.

*Chu.*

"Ah..."

"Oppa, I want that too!"

My younger sister clings to me as if she’s made a fantastic discovery.

Hug.

I also plant a kiss on Yuna’s forehead.

"Hehe..."

Yuna smiles happily, as if the kiss she received from her brother was delectable.

Is she buying underwear with the coin her brother gave her?

Quite desirable, indeed.

On the way home.

[**Yuna**]

(revealing photos of Yuna and Isolde’s underwear.)

...A photo arrived that satisfied my curiosity about the fitting room.

Yuna lifted her skirt to reveal her white cotton pants.

Isolde removed her jeans, leaving her bare legs clad only in pink underwear.

...

[**Yuna**]

Did it make you feel naughty? Big brother

[**Ren Asahi**]

I got turned on.

I know I shouldn’t react like this to my sister’s underwear reveal.

But what can I do about it?

[**Yuna**]

(Emoji of a white rabbit character looking shy and hiding in a hole on the floor.)

"Big brother, have you arrived?"

Before I could open the door and enter, I found **Cleo** waiting to greet me.

"What color are Cleo’s pants today?"

"Is that what you ask as soon as you see your sister’s face? Pervert."

Tightly.

Cleo hugged me while saying that.

Having heard from Yuna that her brother was coming, she must have come out to meet me personally.

Our dear little sister.

"Yellow, like a baby chick."

"Show me inside."

As soon as we stepped into the entrance hall,

Cleo slightly lowered her dolphin-patterned pants before me.

"Hey, quit obsessing over your sister’s pants, you pervert."

"I’ve seen enough."

Now, even being called a pervert doesn’t faze me anymore.

"Did you enjoy your lunch yesterday?"

"Yeah, it was delicious."

Glancing at the dish drying rack, I notice that the lunchbox containers have already been washed and neatly put away. In our household, there’s never a day when dirty dishes pile up. It’s all thanks to Yuna.

"I saved some for you, too. It’s in the fridge."

"I had a hamburger for breakfast."

"With whom?"

...With whom? Cleo’s questioning feels so natural that it makes me slightly uneasy. When I sit down on the sofa and start watching TV, Cleo clings to me and asks again.

"With whom~ Who did you eat with?"

"Some sophomores. You wouldn’t know them even if I told you."

"Suspicious... Big brother."

"What if it’s suspicious? Are you going to check up on me like a protective little sister?"

Cleo huffs and snuggles into my embrace. What is this grown girl doing, spreading her legs like that?

In a house with just the two of us, there was no Yuna around.

Cleo whispers while hugging me tightly like a baby.

"Of course. My brother is the pillar of our home. I have to make sure he doesn’t get involved with strange women."

Haha...

The karma of checking the underwear that my sister bought returns so quickly.

I hugged Cleo, who was trying to suspect her brother’s girlfriend, and spoke.

"I had a meal with twin sisters in the second grade."

"Are they pretty?"

"Incredibly so. I only saw them eating hamburgers while facing each other, but they were so beautiful that it made me involuntarily delighted."

"Are they prettier than me?"

"..."

I’m at a loss for words.

My sister is indeed the prettiest, but...

"Hehe."

As if Cleo was satisfied with my reaction, she didn’t budge, sitting firmly on her brother’s cock.

Rubbing, rubbing... gripping tightly...

I watched TV, pampered like a baby.
