Not a younger sister, but a slave girl (END)

“Chulup, chup, chuuup chup-chup, chup.”

“You haven’t sucked a dick before, have you? You’re fucking good at it.”

I shuddered without realizing it, marveling at my sister’s fellatio.

Anyone would think her boyfriend was a fellatio maniac and only gave her head, she’s so skilled.

She grips my dick tightly with her lips, slowly constricting and sucking it up, then going in deep when she comes back down.

The sensation of sucking while licking with her tongue, gripping just enough not to touch my glans.

Like sucking my dick with a vacuum cleaner, that vacuum-like sensation in her mouth is satisfying enough.

“Stop with the bullshit, chulup, and hurry up and cum, tsup.”

She even answers while sucking my dick.

Seeing this, she’s a truly loyal slave, but that prickly attitude just won’t disappear.

Feeling the fellatio she’s doing relatively well, I grope the breasts under her prickly face.

Now used to it, she silently sucks my dick even as I touch her breasts, glancing up at me slightly.

A slave sucking my dick and glaring at me from below.

I’m not a masochist, but this is bound to be hot.

Anyone would get turned on if a woman sucked their dick while glaring as if to kill them.

I want to shove my dick past her lips and into her throat, making her choke.

They call that a deepthroat, right? I want to see the sight of her choking and gagging while sucking my dick, shoved all the way down her throat.

Of course, I absolutely can’t do that now. I can barely hold on as it is, since I haven’t crossed the line yet.

No matter how much I stick it in my sister’s pussy and touch her ass, it’s still not sex.

I could force myself on her, but then she’d really hate me afterwards.

It’s ‘still’ within the acceptable limit, so she’s obviously sucking my dick and stuff.

From the start, she’s a perverted bitch who gets turned on by my words, so she probably thinks this much is okay.

A pervert’s sense of ethics is a bit different. I’m a perverted bastard, so I’m the basis for it.

She probably thinks sex is the limit, and anything else is just a handjob if you cover your ‘face’.

She probably thinks it’s not a sin to get turned on by a stranger sticking it in her pussy.

It’s just a guess, but even if it’s just a guess, it’s probably close to the truth.

Why? Because she’s a perverted bitch that I turned on.

Honestly, if they didn’t know each other’s faces, they’d already be having sex until the bed was soaked.

“Jjuueup, jjuueueup, tsup-tsup.”

“Hey, hey, wait a minute, wait! Hey, I’m gonna cum!”

As if dissatisfied with me holding back, she now sticks her lips right on and sucks.

Like sucking a drink to the last drop, her lips are stuck right on my dick.

Before I can even say anything, she suddenly sucks hard, and my dick, which had been holding out for a few minutes, immediately signals.

My dick twitches and shoots white jizz into my sister’s mouth.

To feel this sensation of cumming in her mouth, I grabbed her head and shoved it into my dick, twitching my lower body.

“Kek, kek-kek-kek-kek! Kek-kek!”

I can feel her protesting that she’s suffocating just from the sound.

She’s struggling to push my body away, but no way, I use the strength of my arms to force her to keep my dick in her mouth.

After cumming all the jizz, I grabbed my sister’s chin and slowly pushed her back.

Spat-

“You fucking bastard, I almost died!”

Does a slightly wet slap hurt this much?

Traces of my jizz that she swallowed were flowing around her mouth.

My sister’s gaze, looking at me after slapping me, is full of annoyance.

That gaze she’s showing isn’t because she hated it until now, but because she really fucking hates it.

I got too caught up in my first fellatio.

I gained the experience of getting a bukkake, but I crossed the line, and my sister smirks, tears welling up in the corners of her eyes.

A slap that seems to say, “Isn’t there a limit, even if it’s like this?”

Even if I reflect on whether it’s too much to make my sister drink my cum even though she hates it, it’s already too late.

My sister barely calmed her rough breathing and left the bathroom.

…It seems my sister wanted to be something other than a slave to me, but I still don’t understand that.

–

My sister left on Sunday morning, and I also went out after receiving an errand from my father.

I thought things had completely gone wrong after yesterday’s bukkake incident, but surprisingly, she left a KakaoTalk message, letting me know where she was.

I was thinking about apologizing, but it seemed like it would be better to apologize in person.

I just replied, “Okay,” and sat at the terminal, waiting for someone.

My father said, “You’re just lazing around at home, so bring your cousin home,” after hearing that my cousin, whom I hadn’t seen in almost 10 years, was transferring to a nearby university and coming to visit… so I came to the terminal.

Everything’s fine, but the cold wind of February still feels like it’s piercing through my padding, which is annoying.

It’s been a while since I’ve seen my cousin, so even if it’s awkward, it’s not a bad thing.

10 years ago, she was just a little kid, and she listened well… so if she hasn’t gone astray or changed, she’ll still be a good kid.

It’s been 10 years since I’ve seen her, so I’m a bit awkward.

If the kid doesn’t listen, I’ll just stop talking to her. She’s an adult, so there’s no need to force a conversation.

An hour has passed, but there’s no sign of my cousin.

It’s so cold that my teeth are chattering, and I want to go home soon, but she’s not coming.

‘Ah, could it be that she doesn’t know my face and went home first?

It’s possible that my father didn’t tell her what I look like.’

My father doesn’t have many opportunities to take pictures of his son’s face, so it’s definitely possible.

I don’t have my cousin’s phone number or face, so it wouldn’t be strange if we passed each other without seeing each other.

Feeling like I waited for nothing, I shook off my shivering body and tried to leave the terminal.

I should buy some hot food on the way home and go in.

If I wait at home, my father will let me know, so let’s just go home.

“Oh, are you perhaps Seonho oppa… you are!”

When I turned around after someone spoke to me from behind, there was a blonde woman looking at me very clearly.

A smile that calls me oppa and grins.

That’s strange, I don’t think my cousin was like this?

She’s tall, about 170cm, with short hair, dyed blonde.

Is the cousin who’s smiling so brightly and looking for me really my cousin?

The cousin I struggled to remember was a gloomy kid who only drew pictures in the corner?

“…Who are you? The cousin I know isn’t like this?”

“Wow, that’s too much. Seonho oppa, you forgot me?

It’s Eunha, who used to play with you! Choi Eunha!”

Just when things were getting a little awkward with my own sister.

My cousin, Choi Eunha, who looked at me with a smile, came to our house.

Is this an opportunity, or the beginning of trouble?
