Blood Is Thicker Than Water (7)
The darker the surroundings, the easier it is to notice even the faintest star. The quieter the environment, the easier it is to pick up on the slightest sound.
"…."
Unlike just a moment ago, I was alone in the small room, monopolizing the bed. From far away, I could hear my sister’s voice—a sharp, high-pitched cry.
"Ah, youth~, youth."
That much, I had expected. Lying there wearing the shirt Seo Woojin had just given me, I pulled the blanket up with a satisfied smile. My sister… she was obviously making all that noise on purpose out of jealousy. It was so transparent. You’d have to be an idiot not to notice after the looks she was getting in the living room just now. An idiot.
But you know what? When she does that after Woojin and I have had plenty of sex, it just feels like a cute puppy barking to mark its territory. Like, for example: Master, you can't go over there. She's a bad girl. Something like that?
"Heh-heh…."
I suppose next will come the sweet, moaning sounds. If they’re already that loud, I’m worried about how I’ll face the neighbors later.
With such trivial thoughts, I lay in bed and listened. Of course, with the bedroom door wide open.
What if, after I’ve gathered enough intel on how my sister enjoys herself with Seo Woojin, I do the exact same thing to him tomorrow? And what if it feels even better on my end…? How would the two of them react?
Seo Woojin would love it; he’s a man who looks fine on the outside but is a bit rotten on the inside, just like me. And my sister, the pure-hearted one? Would she puff up her cheeks in a pout?
"…I want to see my sister’s face…."
In the midst of the peaceful silence, a sense of depravity began to build up. Soon after, from the room beyond the wall, I heard my sister’s voice resisting: No, no.
…Ah. It’s hilarious. What do you mean, "no"? You’re just going to pretend to resist and then give in anyway. Is that some kind of concept? A schoolgirl sister getting ravished by a delinquent Seo Woojin? No matter how much she wants her boyfriend’s attention, isn’t that script a bit cute?
I mocked her briefly while lying in bed. Then, from the room where they were murmuring, another sound reached me.
— Hiiik……?!
A sound like a gasp that she couldn’t hold back. It was typical of her, I suppose. A moan that was more cute than lewd. Would it be better for me to make moans like that, too? Or should I just not think about it and let them come naturally? As I idly wondered which one was Seo Woojin’s preference, a few more similar moans followed, and then another sound reached my ears.
— Pa-ang. Pa-ang. Pa-ang.
Exactly three times. It was… louder than I thought. Much louder than what I had heard from my own room. The sound of a man and a woman colliding violently.
"…."
…Well. It was one of the things I’d expected. I’d even lent my boyfriend to my younger sister; it wasn’t like they were just going to relieve their urges and be done with it. Besides, the sex I’d eavesdropped on over the phone had seemed quite… intense, hadn’t it?
…So, yeah. It’s more violent than I thought. I think that’s the right way to put it.
"…."
As I held my breath and listened, the sound that had paused for a moment began again. Naturally, it started painting pictures in my head. My sister, her pelvis gripped tightly by Seo Woojin, acting as a human onahole while he pounded into her. My sister, smiling vacantly as if it felt good. Seo Woojin, looking down at her with satisfaction. …And finally, his cock—the one I’d just sucked on, which must be slick with my sister’s fluids right now. All of it.
"…."
Perhaps because that vivid imagination felt a bit bitter, my thoughts shifted. Just a moment ago, I’d planned to lie here comfortably and use my sister’s struggle as a side dish to relax. But… listening to it, I changed my mind.
Why should I hold back? If Seo Woojin tells me not to interrupt and to just play games in my room… do I really have to listen obediently? …It’s not like we have a master-servant relationship. I don’t want to. I want to… tease my sister for being a loser who can’t even keep her own boyfriend.
"Up we go."
I finished my thought, pulled the front of my loose shirt, and stood up. Then, I silenced my footsteps as much as possible, crossed the threshold, and crept toward my sister’s room like a cat. As the distance between my ears and my sister’s room closed, the sounds I hadn’t heard before grew clearer.
— You came…… you came………♡
— So, what.
— Th-that is….
— Hoo…, …lift your hips more. Quickly.
— …Ugh, I really don’t……. Hiiik…?! He-et…….
Amidst the breathless gasps, the short conversation. The pounding sound that had been echoing for a while. The heavy creaking of the bed carrying the two of them. A moan that sounded more lewd than the ones I’d heard earlier… like a female in heat. In the living room, which had become filled with such sticky things instead of its usual silence, I…
"…."
Swallowing my saliva, which was laced with tension, I reached out carefully. *Click.* I made sure not to make a sound. I lowered the door handle to my sister’s room. …I pulled it. As soon as I opened it, I inhaled the thick, erotic scent that had spread to the tip of my nose. I stepped inside.
"Se-enior……, …. Stop, no…. Hit…?!?"
"Hoo…."
"…."
As soon as I entered the room, I looked to the right. …Watching Seo Woojin’s sweat-drenched back, I walked toward him. Along with the sound of Seo Woojin’s hard lower abdomen slamming against my sister’s buttocks, I took in the wet, squelching sounds of their fluids that I hadn’t heard before. …He hadn’t noticed me yet, so I walked stealthily toward Seo Woojin, who was gripping my sister’s jet-black hair with one hand and fucking her like a beast. I walked up to him, and then…
With my fingertips. I tapped his hard pelvic bone. *Tap, tap.*
"…."
I looked up at Seo Woojin, who flinched in surprise, and pursed my lips.
"…."
— Don’t mind me.
— Keep going.
185 …You really are a crazy bitch, Lee Jiyoon. When I found out your true nature, I thought you were "subtly twisted," but I didn’t think you were to this extent. It seems I need to re-evaluate Lee Jiyoon. You’re a much more twisted bitch than someone like me.
"…Ugh, *phoo*……."
To accommodate such a crazy bitch, I let go of Lee Hayoon’s ponytail, which I’d been pulling until now. Contrary to before, I pressed down firmly from her erector spinae muscles to her shoulder blades and continued the insertion. For now, it was better to deal with Hayoon’s gaze somehow. Once she got used to this situation, it would be a different story, but right now, it was obvious she’d growl the moment she saw Jiyoon, so how could I show her?
"*Eung-hik*…, Senior, wait a moment…. Let me rest…."
"…Not until I ejaculate once."
"I’ve already…. three times…, *hik-ugh*…, fo-four times…."
"Hayoon-ah."
"Ye-yes…."
"I’m not really curious about how many times you’ve climaxed. …Lift your hips more."
"That’s mean…."
"Hurry."
As Hayoon buried her face in the pillow and began to moan, Lee Jiyoon, who was next to us, began to cautiously move around the bedroom. If even a hint of her presence leaked out, Hayoon would try to kill her. Is she thoughtless? Or is she a bitch so deeply immersed in depravity that she’s willing to take that risk?
"…."
Even while thinking she was out of her mind, my left hand, which had fallen from Lee Hayoon’s waist, was flicking toward Lee Jiyoon, who was wearing only my shirt.
— Why? Lee Jiyoon, who asks even though she knows everything. Lee Jiyoon, who came here to do this but pretends not to, making excuses. I looked into her dark green eyes, which were smiling brightly as she approached the bed as if to climb on, and then—*grab*—I pulled on the shirt she was wearing.
"……, …*chup*…."
Secretly, while Lee Hayoon was climaxing again, her rear entrance twitching, I continued to kiss her younger sister. Our front teeth bumped against each other, and we were in an awkward state. We were so excited that we were licking each other with all our might, putting strength into the tips of our tongues. …Frantically.
"…*Hik*…, please pull your cock out…. Se-enior……."
"…*Pheu*……. Hoo……."
Lee Hayoon was still deeply immersed in her role-play. Far from slowing down, my waist, which had been violating her, moved even more—much more—violently. …With the intent to crush her womb, I pounded into that most secret space in the back. Even though Lee Hayoon, whose hips were twitching, was begging for forgiveness without even knowing why. Even though she was letting out wanton moans I’d never heard before. I ignored it. I kept going, so the squelching sound of water wouldn’t stop.
"If you put it in that far…, you’re not supposed to…."
"…."
I patted Lee Hayoon’s waist, as she couldn’t even breathe properly, with one hand. With my remaining arm, I pulled Lee Jiyoon’s head toward me. I pushed my blood-engorged cock forward until Lee Hayoon’s soft buttocks were distorted, making the sound of my cock slamming into her—which filled the bedroom—even louder.
"Senior, I, I won’t report you to the police, so…."
"……. Hoo…."
"*Pha-ah*…. …Ha…."
"Only up to here……, ah, *eung-hik*…?! *Ugh*, *eug-euk*……♡"
Had it been about a minute? After sharing a long kiss, Lee Jiyoon’s lips parted with a small sound, as if she had no intention of hiding it. I buried the sound by pressing down hard on Lee Hayoon’s body and violating her mercilessly—*thwack, thwack*—and then lowered my gaze to follow Lee Jiyoon, who was giggling and moving downward.
"*Eung*, *keuk*…. Senior……. Senior’s cock, it’s amazing…."
"…."
…My collarbone. My chest. On various parts of my body, which must have been dirty from sweat, she was leaving her marks using her lips and tongue, secretly from her sister. How could I not look? *Fuck.*
"Ah, Senior, Senior…. Don’t, don’t pull my hair…."
Lee Jiyoon, who was clinging to me and licking my chest without even feeling sorry for her sister. Instead of sharing more gazes with her, I pulled Lee Hayoon’s hair again and pushed my glans in to the limit. The first reason was that I didn’t like Lee Jiyoon’s playful expression. …Getting caught was only a matter of time anyway. Then, perhaps it would be better to be caught while Lee Hayoon was out of her mind with pleasure—that was the second reason.
But unfortunately.
"*Eung-at*…. I’m coming, I’m… coming…. Being forcibly raped by Senior…."
Lee Hayoon just gripped the bed tightly so she could be pulled better, and every time I pounded into the root of my cock, she just let out bitch-like moans. I pulled Lee Hayoon’s ponytail tight and slammed my cock in, as if to destroy her favorite erogenous zone, deeper than her cervix. Enough to scatter the beads of sweat on her skin across the bed. Enough that Hayoon, who had always called me "Senior," was now busy just letting out lewd moans.
Lee Jiyoon, who had been licking my body just a moment ago, giggled and slowly lowered her body, then—*tap, tap*—brought her index finger to her mouth, which she had opened wide.
"…Fuck. Seriously…. Hoo…."
My reason snapped. It snapped and broke, and I pounded my cock into Hayoon’s inside until I was on the verge of ejaculation. …Secretly, while Hayoon was panting and dirtying the bed with her fluids—*fyu-ut, fyu-ut*—I grabbed the head of Lee Jiyoon, who had opened her mouth like a toilet right next to me.
*Vrr-rr-rt, vyoo-ut, vyut.*
I poured all the semen that would have been wasted inside a condom. Into the mouth of the woman’s younger sister whom I had just violated. …Even though she couldn’t even swallow properly and was drooling semen out of her lips, I didn’t care. *Vrr-rr-rt, vyoo-ut*…. As if vomiting out everything in my semen pouch.
"…."
…Immediately after that. Lee Jiyoon.
"*Haa-ah*…. *Ha*…. *Haa*…."
She rolled the semen in her mouth, then—*spit*—she spat it out onto her sister’s trembling buttocks, as if I had ejaculated there, and then she giggled prettily and left the room. Leaving behind only the meaningful words: "See you tomorrow."
