Gaslighting
"Ugh…." I kissed her as quietly as possible. I held my breath, trying not to make a sound that anyone else might hear. I didn't even dare to use my tongue—or rather, I kept it to a mere touch. "Haa…." A thick, heavy tension hung between us, like a concentrated dose of dopamine. I knew the clothes I’d carefully put on would be ruined, but I didn't care.
"It’s so hot…."
"That’s because you’re all over me…." Chaeyu was straddling my lap. Even though it was night, it wasn't cold; it was stiflingly hot.
"Can’t we take them off?"
"Please, just hold it in while we’re outside…." I tried to tell her that even if she didn't know any better, there were lines you just didn't cross in public, but I knew she wouldn't listen.
"Then let’s go to the car."
"The car?"
"Yeah… it’s cool in there."
"…Alright."
We were at an outdoor parking lot by the Han River. Contrary to what Chaeyu had promised, the inside of the car was boiling.
"It’s hot!"
"Just wait a second for the AC—hey!" Before I could even turn the ignition to get the air conditioning running, Chaeyu began stripping as if she’d been waiting for this moment. I quickly killed the interior lights.
"What are you doing, just taking it all off like that…."
"I told you it was hot."
"Even so… haa…." Despite my words, my eyes were glued to her chest. The scent of sweat rising from her skin made it impossible to look anywhere else.
"So… are you just going to leave me like this? Your little sister who’s been pent up for days, dying to do it—ugh!"
Since we were in the backseat, it was easy to pin her down. This time, I didn't bother holding back the sounds I’d been suppressing. "Ugh, heuph…!" I made wet, smacking sounds as I pushed her down. As she fell back, her breasts swayed heavily, and I began to suck on them immediately.
"Mm…!" The thought of breast milk kept circling in my head. I shouldn't be thinking like this—damn it, Aunt really ruined me.
"Ahhh!" It had been a while, so her reaction was predictably intense. My fingers dug into her skin, finding a perfect grip.
"Oppaaa…." Chaeyu groaned, her hands tangling in my hair. She tried to push me away in a half-hearted attempt at resistance, but it was useless.
"Ugh… haa…." Our eyes met, her face completely flushed and undone. She offered a faint, soft smile and kissed me again. "Heuph… slurp… ugh…."
Our bodies tangled together as she climbed back on top of me. I didn't know when she’d finished undressing, but she was down to nothing but her panties.
"You’re soaking wet."
"Because… we haven’t been able to…."
"……."
I felt a pang of guilt. While Chaeyu had been waiting, I’d been having wild, messy sessions with Mom and Aunt. I was the only one who’d been enjoying myself.
"Ugh…." As I stripped off my own underwear, my cock brushed against her. Feeling the dampness against my glans, I pushed her panties aside.
"Ugh, mm…! Hii-?!" As she slowly lowered herself onto me, she seemed to lose her strength and collapsed down all at once. My cock slid deep inside, hitting something hard. Before I could even think about how tight she was, the first thing that crossed my mind was that it must have hurt.
"Are you okay…?"
"It… hurts…."
It wasn't that I’d thrusted hard; it was just that getting impaled like that by accident was incredibly painful. If I wasn't careful, she could even get a vaginal spasm.
"Ugh… I’m so annoyed… why does it have to be like this with me…."
"……Are you crying?"
"I’m not crying!"
She said that, but I could feel the warmth on my shoulder where she was leaning. It must have really hurt. "It’ll be okay."
"Mm…."
Her pussy, stiff from the pain, began to relax, and her whimpering stopped. When she saw me smiling at the tear tracks on her face, she puffed out her cheeks and said, "Kiss me."
"Okay."
I comforted her with a gentle kiss. Under the soft movements of my tongue, her pussy twitched and reacted. "Ugh… heuph…." Her breasts pressed against my throat, making it hard to breathe. It felt like I was receiving a *paizuri* with my neck.
"Oppa…." Chaeyu, oblivious to my current state, continued to explore my lips. My hand stroked her soft back, tracing her spine until it reached her hips, and I began to knead them.
"Ah, ugh, hnn…!"
Chaeyu began to move her waist little by little. The way her insides coiled around my cock, and the feeling of my glans scraping against her vaginal walls, made me forget the sweltering heat of the car.
"Oppa, oppa…!"
"…!"
Chaeyu’s hip movements reached a crescendo. Below her still breasts, her waist was thrashing violently, tormenting my cock.
"Wait, stop—"
"Haa?!"
Chaeyu clamped her legs together, squeezing tight. Before I could pull out, my semen surged out in a rush. I pulled back a second too late; it felt like it was already too late.
"Haa… haa…."
The semen that had shot upward was smeared across Chaeyu’s waist. The rest had splattered all over the interior of the car.
'I’m screwed….'
The thought of my cock trying to impregnate even the car was terrifying. And the thought of the sperm trying to impregnate Chaeyu was even more so.
"…Did you take the pill?"
"Yeah…."
The next day. We’d barely managed to clean the car, and since Chaeyu fortunately had an afternoon shift, she went to the clinic first thing in the morning. She said she’d gotten the morning-after pill. Maybe that was why her expression was so sour.
"It was a safe day, so it should have been fine…."
"Did you do it? When?"
"Ah… yeah. On Friday."
"Aha…."
So that was why she’d been so furious when I broke that statue. No, she probably would have been like that regardless of the day.
"Anyway, you still can’t do that. You never know."
"We didn't do it then, either."
"When?"
"Our first time… back in the day. Remember?"
"Ah. When we broke up."
"Yeah…."
Come to think of it, we had done it raw because it was supposed to be the last time. Thank god we didn't back then. If she’d gotten pregnant… just imagining it was terrifying.
"Are you not feeling well?"
"A little… I’m dizzy."
I caught Chaeyu as she swayed slightly. She leaned into me, letting out a shallow breath.
"Chaeyu, what’s wrong?"
"Ah…… I think I’m just not feeling well."
"Really? Is your period pain still the same?"
"Mom! Why are you saying that out loud!"
"Is this really the time to be picky about that when you’re not feeling well?"
"……."
"Take some painkillers and lie down."
"…Okay."
"I’ll go get them for you."
We managed to brush it off, using her period pain as an excuse. I had no idea the side effects of the pill would be this bad. I’d have to be more careful from now on.
"Here."
"What about the medicine…?"
"They said it’s not good to take them together."
"I see…."
"Drink some water and rest."
"Oppa."
"Yeah?"
Just as I was about to leave after making sure she drank the water, she called out to me.
"What would you do… if I got pregnant?"
"……I don’t know for sure, but wouldn't I just die?"
"Why?"
"Because it’s not just anyone, it’s you I got pregnant?"
"What is that supposed to mean…."
Pregnancy before marriage is incredibly dangerous unless you have plans to get married. It’s a tragedy not just for the people involved, but for the child as well. We couldn't even get married in the first place, so the term "pre-marital" didn't even apply to us.
"If I survived, I’d probably just run away somewhere with you."
"Would you raise it?"
"Of course. You want me to abort it?"
"……."
We weren't going to use a pregnancy test every week, and by the time Chaeyu realized she was pregnant, it would be something far beyond a cellular level; it would be impossible to erase. I’d heard it was bad for the mother’s health, too.
"Anyway, I’ll be careful not to let you get pregnant. I’m sorry."
"Why are you apologizing? It’s not your fault."
"I’m the one who provided the cause, anyway."
Of course, wearing a condom didn't guarantee 100 percent safety, but getting pregnant while wearing one versus getting pregnant without one were two completely different things.
"Do you hate the idea of me getting pregnant, Oppa?"
"……I do."
"……."
We were in a relationship that shouldn't even result in children. We were just siblings. Siblings who used to be sex partners, and are currently sex partners. Because we’re siblings.
"For now."
"For now…?"
"…I don’t know. Forget what I just said."
"What does that mean? Tell me."
"I don’t know either."
"…The limited edition statue."
"That trick doesn't work on me anymore."
"……You almost got me pregnant, though."
"……."
Please, stop using that trap card on me….
"It means exactly what it sounds like—I don’t want it right now. Things like that need to be planned."
"So you don't mind if I get pregnant?"
"That’s not what I meant… haa."
"Don’t go."
"You’re a patient, just get some rest."
"You’re so mean."
"Sleep well."
"Yeah."
I thought I’d finally managed to crawl out of that swamp. It seems I’ve only sunk deeper.
"Haa…."
"You’ve been looking low on energy lately."
"Work has been tough…."
"Has it been over a year since you joined?"
"Almost."
This month was my eleventh. In a little while, it would be my one-year anniversary, which meant severance pay and annual leave. By the one-year mark, you’re expected to understand most of the work and be able to push forward with new projects. That’s why the workload keeps increasing. Though, that wasn't why I was tired right now.
"I see. That must be hard."
"I have to do it, though. If I want to stand on my own two feet. I can’t live at home forever."
"Are you going to move out?"
"……Someday, wouldn't I?"
"Should Mom come with you?"
"…Excuse me?"
"Just kidding~"
Mom laughed and tapped my shoulder. …That didn't sound like a joke.
"Now that I think about it, you’re right… you kids should be independent…."
"I’m not doing it yet, so don’t worry."
"I’m worried Chaeyu will never move out."
"Didn't she say she had experience living on her own?"
"She lived on her own, but she wasn't independent."
"Aha…."
I guess so. Independence requires being fully detached from your parents, both economically and mentally. In that sense, Chaeyu still needed a lot of Mom’s help. Especially regarding her dreams.
"Haa…."
"Stop sighing. You’re going to sink the floor."
"Was I sighing?"
"Yeah. You’re so tired you don’t even realize it?"
"……."
To think I was sighing without even knowing it—I must really be exhausted.
The constant, burdensome demands from Chaeyu were draining me. Ever since that last time, it felt like she’d started obsessing in a strange way. Of course, when the time actually came, she never followed through, but every time we had these conversations over text, I was put in a very difficult spot. It wasn't like she had heatstroke.
"Haa…."
"See. You’re sighing again."
"…I’m sorry."
I kept sighing like that until I arrived at the office. I barely managed to hold back another one.
"Son."
"Yes?"
The moment I stepped out of the elevator, Mom called out to me. Her face looked unusually serious.
"Is something going on with Chaeyu?"
"…Chaeyu?"
"We’ll talk later."
Before I could offer any explanation, the elevator doors closed. What was that about? Could she have found out?
