The Leash
Hayeon's question flew at me like a dagger, stabbing straight into my heart. Because it was true that it had felt good. The first-time sensation of our genitals touching was enough to leave me floundering in pleasure. I don't know how many times the urge to simply hurl my mind into that ecstasy had gripped me. But every single time, the face of my little sister—something I absolutely could not look at with open eyes—rose before me. The expression of a bitch lost in heat. What older brother could see his younger sister's face like that and not feel revulsion? And the fact that I had gotten hard and physically surrendered to such a sister made me loathe myself just as much.
Unable to face this reality, I squeezed my eyes shut and wrapped myself in darkness, but blocking my vision didn't kill the other senses. She stood up.
“Haah… Even the second time and you still came this much…”
I felt the slippery, warm fluid covering my now-softened organ. She might grab my hair again and force me to look at the nauseating sight, but I lacked the courage to open my eyes myself. Finally her hand touched my head, and I flinched. Her touch was only a gentle stroke, yet my body kept trembling. It was a revolting caress.
“You did well, brother. I felt so good.”
A sticky whisper, thick as sugar syrup, defiled my ear. I fought down the impulse to spit curses. I clung to the sweet hope that if I just stopped provoking her, this might be the end.
“Take good care of me from now on too, okay? My sex drive needs handling♡”
As if that would happen.
“I'll wash you. Managing the sex tool is the owner's job, after all.”
“I'll wash my own body.”
I opened my eyes wide. If there was no turning back, there was no need to look good for her.
“I'd love to wash you myself… but an automatic cleaning function? What a cutting-edge sex toy?”
She held the showerhead out to me, watching with an intrigued expression as if she meant to savor the sight.
“Get out.”
I worried my cold tone might turn her into a savage beast again, but I simply could not treat her warmly.
Surprisingly, she obediently rose, hooked one leg over the edge of the tub, and began washing her own sex first.
“Haah… What a shame. I should show this to Mom. Tell her that her son pumped so much cum into his little sister's pussy♡”
“What…?”
Fresh terror coiled around my entire body.
“Don't forget. The happiness of our family depends entirely on how well you behave, brother.”
The threat that she could reveal the truth to Mom at any moment.
“You… you didn't actually do anything good for Mom, did you…”
“You finally figured it out? That's right. I still hate that woman. I wonder how she'd feel knowing her own son and daughter fucked each other? I'd love to see it. That look of utter despair♡”
A demon stood before me, lips curled in a cunning smile.
“So remember this. There's nothing to gain by rejecting me.”
She sensually stroked her own body right in front of me, finished her shower, then said while drying herself with a towel,
“Let's do well together, okay? Brother♡”
before walking out.
I turned on the hot water to rinse away my cold sweat, then poured it across the tub floor that was still coated in semen. The mucus clung stubbornly to the bottom and refused to wash away with water alone. Things I had touched without a second thought before now felt repulsive today, but I had no choice but to scrub them with my hands and send them down the drain.
I closed the now-clean drain and began filling the tub again. Hot water rose around my tightly curled body. As the shock that had been tearing through my mind began to fade, the root cause of this catastrophe rose naturally to the surface. I tried to defend myself by saying the real villain was Monkey's Hand, but I couldn't summon anger toward something I didn't even understand. My misplaced resentment turned inward. A single wrong wish had driven everyone insane. A moment of jealousy and desire—my own stupidity—had twisted everything beyond recognition. If I had only known what the Monkey's Paw truly was, if I had thought it through and done even the slightest research, none of this would have happened. Who could have imagined it would include my younger sister, a girl whose beauty was objectively flawless? And would I have even cared whether she had any experience or not?
Besides, the wishes influenced each other. At first I thought I was simply more excited than usual because I had no prior sexual experience, but after feeling my strength drain twice, I understood. This abnormal erection strength and semen volume were likely a supernatural ability born from my wish—one that gathered all my energy into my manhood. That was why, even as the older brother, I had ended up overpowered. Still, something from yesterday morning didn't make sense. I clearly hadn't felt my strength leaving me then, yet I still couldn't push Hayeon away. Had the gender reversal also reversed physical strength itself? The hulking men who had come rushing over today out of worry for me didn't seem like the type who would lose to a slender woman in a contest of strength. Juran might be an exception, but even so. Just because I couldn't picture it didn't mean it wasn't real. I had never once imagined my sister, drenched in lust, looking at me as prey. A cold shiver ran down my spine.
When I pulled back the shower curtain, a pair of gleaming eyes stared at me through the slightly open door.
“Ugh—fuck!! You scared the hell out of me.”
Was she going to devour me again…?
“No sound was coming out. I had to make sure you didn't make any wrong choices.”
I'd made the wrong choice on Sunday.
“You seem worried. After doing something like that…”
Maybe because part of me still blamed myself, my tone had softened. My mood had sunk beneath the surface, but not far enough to drown my breathing entirely.
“I won't die, so just close the door. It's cold.”
I couldn't abandon everything and leave while only a sister who hated our mother remained.
“Uh… okay…”
She started to say something, then obediently closed the door. If I tormented her any further she might actually stage a suicide attempt, but since I had no real intention of dying, that would only escalate things. She might even tie me up to prevent any nonsense and keep me under surveillance. After seeing her earlier, I wouldn't put it past her.
Click. Clack—…
The sound of the door lock opening reached me.
“Ah, Mom's home?”
Hayeon's bright voice welcoming our mother was sickening, yet better than open contempt. Now that I knew Hayeon's true feelings, the situation felt even more precarious.
“Yes, my daughter. What are you doing squatting in front of the bathroom?”
“Brother's inside, so I'm waiting. Brother, stop soaking in the tub and come out already. Mom's home.”
“In the tub? That's unusual…”
I rarely filled the tub at home.
“Mom's here? I'll be right out!”
I couldn't keep agonizing forever. It was a precarious peace built on lies, but because Hayeon greeted her so warmly, Mom's voice sounded that bright. I wanted to protect it. As if nothing had happened.
The brother who emerged from the bathroom helped Mom prepare dinner.
“I'll help too.”
I stepped forward because I wanted to stay close to him, but he stopped me.
“You rest.”
He was subtly sharpening his tone. Toward me, of all people. I wanted to slam this insolent flesh slave to the floor and rape him right in front of that bitch, but that would be throwing away the cards I held, so I endured it. The only reason I could use brother as my personal sex handler and the only reason he couldn't leave this house freely was because that woman existed. Because that woman was smiling. Fuck. This feels so goddamn disgusting.
I sat in the living room, staring at the two bitches laughing and chatting in the kitchen, lost in thought. Brother must know too. That that woman is a cock-hungry bitch in heat. Our family fell apart because of that horny dog, yet he still wants to protect this broken home? And even so, she has no intention of eating him? Really? Brother. I wonder if that rag can resist drooling from her cunt when she sees your incredible cock. After messing around so much that she divorced Dad, now she wants to fuck a man with a big dick? Is she actually insane?
The Kkotok conversation I had seen by chance—messages exchanged with her friend—floated into my mind again, and fresh hatred surged. I wanted to show brother that bitch's vulgar true nature hidden beneath her caring-mother act. But no. I couldn't. That male dog cock that inherited her blood and got hard for any woman would probably stand at full attention even for that rag. How could I bear to watch that? I'd lose my mind and who knows what I'd do.
“Hayeon, let's eat. Everything's ready.”
Fucking bitch. So goddamn hypocritical. But I'll play along. After all, you're the weight at the end of the leash I've fastened around brother's neck.
“Thank you again today, Mom. You must be tired from work, yet you prepared a whole meal for us.”
“What's tiring? These days Mom feels so energetic, you know?”
I let her voice—which I had no desire to hear—flow past me and glanced at brother. His face, twisted in disgust as if he'd seen something filthy, shifted into an awkward smile the moment our eyes met.
Yes, that's good. Brother. You can hate me. You can despise me. For now… it can't be helped. But don't bare your teeth. First, learn to obey me on the surface. Start by becoming my faithful dog, brother♡
