Chapter 18

"...."

"..."

I fell onto the bed, with my hands tied behind my back.

She looked at me and tried to say something, but it was difficult to swallow.

She seemed to want to say something, but then stopped.

She was looking at me with her eyes, but she didn't say anything.

"Zee, it's Earth."

"Mmm."

Finally, Goldie called my name.

I could feel the skin on her legs and bottom as she sat on top of me.

My gogan shuddered and jerked involuntarily.

"Ugh...!"

"Oh, no, sister, you know it's an inevitable reflex."

"Yeah, right, that's what I... decided to think."

What the hell.

She understood that the living room was the realm of instinct.

She climbed onto the bed and looked at my bum several times, as if she thought she might be right.

"I trust you, Terra."

"Aww, thanks, sis."

She didn't seem to believe me.

She grabbed my wrists and held them together, pinning me down and stopping me from moving.

She kept saying she believed me and wanted to believe me.

I told her it was a silly idea, and I never thought that would happen.

I could hear the others' unconvincing voices in my head.

Geum-bi's eyes moved between my face and my gogan. Then she cleared her throat and spoke again.

"But... I don't want to ignore the problem just because of my faith."

"Mmm."

"You know, Terra, we can't just take your word for it here."

I nodded.

I'd had a nasty erection while snuggling with her, and she hadn't died when she came into the room, and I'd been talking about "teaching her about men" the whole time.

"On the contrary," she said, "I've had a good dose of that."As usual, she wouldn't have anything to say if I kicked her in the balls."

When I agreed, she loosened her grip on my hand, as if a little relieved.

But she didn't leave my stomach and brought her hand to my chest, touching my heart.

"Terra... your heart is beating really fast."

"It's been like this since the start. You too, haven't you?"

"Yes, since before."

To try and make the mood better, they talked about what had happened in the living room.

We lay on top of each other, our hands close enough to hear our hearts beating.

As they did this, I remembered how I had felt before.

Geum-bi leaned over so that his chest was directly in my ear.

"What's wrong?"

"Just a moment... It calms me down."

Trembling, she concentrated on the sound of my heart.

I felt like I was going to be sick because the sound of my heart was so loud.

I wondered if all the saliva in my mouth was going down my throat.

Goldie's eyes opened really wide and she looked at my face.

"Earth."

"Mmm."

"I'll ask you again."

"Yeah... like what?"

"If you'd broken up with him earlier in the lounge downstairs, how would you deal with it?"

Geum-Bi stopped worrying about that and went back to talking about something else.

But I was still as confused as before, and I scratched my head quickly with my free hand.

"You know, sis, a man is a creature... just because he has an erection doesn't mean he has to get rid of it."

"Huh? Zee, really?"

"Yes. Is that the system? Is anyone who has an erection outside the home or in public considered a pervert?"

"Do men... just get erections in those places?"

"No, they don't just get erections, that's what I'm saying, Ye-shi."

I explained slowly and logically, trying to calm down Geum-bi, who was touching herself in strange places.

She's clever, so she understood what I was saying after a bit of thought.

"So... you're saying that if we put this aside, everything will be fine?"

"Of course."

"But... why is he still growing now?"

"What?!"

"It's strange... what you said made it sound like it should have sunk a long time ago, but it hasn't changed down here since we were on the first floor."

She was the sister who seemed to know nothing about men, and she poked him where it hurt.

I couldn't make the situation sound better, so I covered my eyes with my arm and admitted what had happened.

"It's because you're constantly, non-stop, ugly."

"Huh?"

"I mean, it's because you're always annoying me...!"

"Eh? Eh? Eh?!"

Geumbi's face was bright red as she looked through the small opening.

I wasn't sure if it was because of the kissing that had been going on since the first floor or because of what I had said.

But after seeing Geumbi's face, I was still hard.

"Anyway, if I fall off you, it will go down by itself, and you won't have to worry about... anything."

"Ah, uh, yes. I see."

I crossed my arms in front of me, barely able to say what I wanted to.

I still don't have the courage to look him in the eye, so I keep my gaze fixed on the ceiling.

I breathed out deeply, and it felt like all the ice in my heart melted away.

After about 15 seconds, she spoke.

"But you know something, Terra."

"Huh?"

"When you get back, you're going to sleep with Crystal by your side, right?"

"Yeah, I guess so."

"And yet... can you calm down... or are you just getting more excited?"

"...!"

What is this sister trying to drag me into?

I was stunned, but at the same time I couldn't say no, so I covered my eyes with my palms.

Geum-bi, who was watching, remained silent for another moment.

When the silence was even heavier, and more intense than in the living room, his fingertips brushed my thigh.

"Hmph?"

"You know, earthling."

"Mmm, sis."

"I think you should take this off."

"Why do you think that?"

"Because you're drunk in your room, and if I'm not there... there could be an accident."

"How about in the bathroom?"

"The bathroom door is broken, I'm in the middle of something... what if my sister stops to use the loo?"

I calmed down and suggested we could both take our clothes off, but she refused.

At the same time, a hand had found its way between my thighs and into my crotch.

'But the bathroom is on the second floor, right, sis?

Even if my brothers wake up, they're not going to go to the bathroom in the flat in the middle of the night.

I wanted to say this, but Geumbi was touching me all the time and I couldn't speak.

"It's the Earth."

"Mmm... go ahead."

"I can't help it, it's for my family."

"Mmm... right."

"..."

"...."

We didn't look at each other.

I stared at the ceiling and she stared at the floor of the bed. Our legs and fingers confirmed that we were there.

Then I touched her, her bump was all over the place, it was moving and twitching.

The moment my nails touched the area, I choked loudly.

"I'm coming, do you need help, Terra?"

Goldie finally found her voice.

She didn't think it would happen, she thought it was ridiculous.

But the words echoed through the bed, and her heart fluttered.

"..."

"..."

"How are you going to help me?"

"With my hands, just over your clothes... a little touch."

I don't know if it was my last bit of common sense or my better judgement that made me ask her how.

Probably not, because if she had any, she would have got rid of that hand a long time ago.

"Please, sister."

My shaking lips never managed to form the right words.

What came out was a sound that should never have come out.

But her voice was so sweet and seductive that I bit my lip and put my right hand on my groin.

"...hhh!"

"Hhhhh."

Her shoulders shook with surprise at the touch of my trousers.

But this made me feel strange, and I let out a quiet moan.

Yes, it was very quiet.

So it must have been a coincidence that she looked this way.

And it was a total coincidence that our eyes met at that exact moment.

"Oh, uh, there's... the Earth."

"Um, that, um, girl... sister?"

"No, is this... okay?"

"Ah, mmm. That looks good."

I wondered what I was saying to my sister.

I wondered where she was holding her sister and what she was asking.

It was dark, so I couldn't see what they were doing.

In the silence, the only movement came from the sensitive touch of their flesh.

Goldie's hand, which had previously felt like it would explode my heart with the mere touch, brushed across my groin.

I looked up at the ceiling again, refusing to look down.

I hoped that she was doing the same.

Please, please, her eyes were fixed on the floor of the bed, as they had been before.

Don't look at that face. Look away, sis.

I felt the tip of my chin on the bed.

The dryness in my throat, the sting of your eyes on my cheeks, it's all an illusion.

It's just like the way her pussy twitches when my sister touches her.

I covered my lips and tried not to make a sound, hoping it was all a dream.

"Ha...!"

"Ugh, huh...!"

If things had been different, we wouldn't be here.

Goldie must have heard my moans, but she kept moving her hands as if she hadn't heard anything.

She had to go to work in the morning.

As I expected, she did not sleep tonight.
