“Hey, one minute left. In one minute, I’m going to take off your panties and check if there’s pussy juice on them.”

“Do you think there’d be any, you moron? I wasn’t even turned on-Eueuk!”

My sister doesn’t say a word even when my hand goes into her bra.

As if it’s okay for my hand to be in her bra, I targeted her nipples first to stop her from speaking properly, with that cocky attitude.

I massage her breasts inside her bra with both hands, pinching her nipples that are standing up so hard they could pierce through the bra.

Every time I pinch her nipples, my sister twists her body, trying to resist, but no way.

Every time she resists, I twist her nipples, teasing her. Like a whip telling her to stay still.

“Heueuk-heu…heueuk!”

Every time I pinch and twist her nipples, a groan escapes from her mouth as she grits her teeth.

Her sense of touch has become quite sensitive since her eyes are covered, so of course, she’ll groan even if I only mess with her nipples.

Even a virgin newbie with no experience can do this much just from the internet. That’s what I’m saying.

Even without stopping my hands, she’s twisting her body but not stopping my hands from touching her breasts until the end.

She’s already turned on and wet, but she’s holding on because of her pride.

Of course, from my perspective, it’s more fun to torment her when she resists like that.

If she weren’t my younger sister, I’d be tormenting her as my personal masochist.

But conversely, if she couldn’t see my face either, wouldn’t it be okay to call her my personal masochist?

I put my hand into her panties and checked, as if giving a gift to my sister who’s gritting her teeth and holding on.

“As I thought, you’re wet! You bitch. You’re going to be my slave, right?”

Without even putting my hand in her pussy, as soon as I put it in her panties, my hand was covered in a sticky liquid.

Sweat can’t be this sticky, so this is definitely pussy juice. It’s clear that what people commonly call vaginal fluid is flowing.

Even when I rub my hand covered in pussy juice on her cheek, she ignores my question, still gritting her teeth because of her nipples being teased.

This bitch. I’m still going easy on her because she’s my sister, but I don’t like the way she’s climbing all over me.

But I do like the way she’s still twisting her body and resisting, insisting that she’s not wet.

Most men can relate to the feeling of conquest of kneeling a woman with strong self-esteem at my feet.

A woman with masochistic tendencies like my taste, and a strong self-esteem that makes her resist.

The feeling of conquest of trampling on such a woman and making her obey me stimulates me.

“Kkeuheuk-kkeuheuheu, kkihik…”

Even after the promised 5 minutes, I kept poking my sister’s pussy.

Her pussy, full of vaginal fluid, didn’t reject my hand, and with enough vaginal fluid to soak my hand,

it sent its gratitude for being poked.

She tries to resist with her legs and arms, but no way.

The desperate look on her face as she tries to stop her vaginal fluid somehow, while I block her resistance with my arms and legs, stimulates me even more.

Poking her pussy also seemed to be stabilizing little by little.

The groans she makes while gritting her teeth are also decreasing and starting to weaken, so now I need to stimulate other places.

“Hiang!”

“It’s been 5 minutes, aren’t you going to admit it?

Do I have to make the living room floor soaked with your pussy juice for you to admit it?”

Her clit must have been particularly sensitive, because when I strongly scratched her clit with my thumb, she couldn’t hold back and groaned.

Her resisting gestures can’t withstand the persistent caress of her clit either.

She tries to hold on by gritting her teeth, but from the start, the clit is a part for pleasure.

Since I’m scratching that part with my thumb, even if she moves her body to resist, I don’t stop.

A gesture as if begging me to stop blocks my arm.

Ah, no way. She’s the type to throw a fit and say it’s invalid if I stop halfway before she admits it.

To help the thumb scratching her clit, my index finger goes inside her pussy and slides up, feeling the upper wall.

“Oppa, please, not there, please! Please, spare that place!”

While going up, as soon as the entering side is touched, I poke that side with my index finger as if almost stabbing it.

My sister, whose G-spot was touched, belatedly begs me.

“Then you should have admitted it sooner, you bitch.”

“Heuaaaaang!”

My sister, stimulated by her clit and G-spot,

let out the most lewd moan a woman can make and soaked my hand.

Not vaginal fluid or lubricant, but urine that she couldn’t hold back from pleasure and squirted out.

Her urine soaked her panties and started flowing out, wetting the floor, and only then did she gasp for breath.

“…You son of a bitch, does it feel good to do perverted things to your sister?”

“I went easy on you since you’re my slave and wanted to get fucked so badly.”

“You son of a bitch…shit, what about this pee? Are you going to clean it up?”

“Why would I? You have to clean it up. You’re the slave now.”

It’s obvious that she enjoyed it herself, crying so much that her blindfold is wet.

Her panting, happy breaths, and the tears of pleasure that she couldn’t hold back are all products I created after all.

Seeing that she can’t refuse even when I tell her to clean it up, it seems she’s finally admitted defeat.

“Hey, you admit you’re my slave, right? Repeat after me if you admit it.”

I am Oppa’s slave from today onwards.

The humiliating words of becoming a slave and admitting defeat.

I can’t acknowledge my victory if she doesn’t say those words.

From the start, it’s normal to need proof that I won, duh.

Considering that she hates to lose, this is essential.

When I turn on the recording on my phone and bring it to her mouth, she tightly shuts her mouth.

Shit, what am I supposed to be if the bitch who even pissed herself can’t admit this?

I don’t know if she thinks I’m a fool or if she’s just completely ignoring me, geez.

“…I am from today onwards…shit, Oppa’s slave, is that good enough? You must be happy making your sister piss herself! You son of a bitch.”

“Hey, the slave’s talking rudely? Watch your mouth. You’re the one who wanted to do this.”

I thought she would close her mouth and hold out, but she finally agrees.

Yeah, she’s a slave from now on, duh. It would be even more of a lie if she said no after I made her piss herself.

I untied my sister’s arms and legs.

She’s still catching her breath, not moving her body, as if the afterglow of the caresses I gave her still lingers.

“Okay, listen to me from now on, you bitch. And clean up the pee on the floor when you calm down.

I’m tired from jacking off my slave, so I’m going to get some sleep. Don’t forget to wake me up later when it’s time for dinner.”

“…You really make it sound like shit until the very end. Are you bragging about having a dick?”

“Uh-oh, watch your language, you crazy slave bitch.”

After having some fun, as I was about to open the door to take a nap, curses flew and hit the back of my head.

She’s the one who wanted to do it, and she’s the one who admitted it and even had it recorded, so why does she keep cursing?

Ignoring her, I went into my room, lay down on the bed, and asked for sleep.

I closed my eyes, thinking about what I should make her do after I wake up later,

but I fell asleep just like that, probably because this was more tiring than I thought.
