The Jealousy of Sisters
It felt like less than five minutes since I’d left the shop. Why does everything have to go wrong today? Is it just one of those days? "Ah, damn it... why the hell won't he pick up the call?"
I was already halfway through my delivery route when the rain started pouring down, which only added to my irritation. I’d used my palm as a makeshift umbrella to keep the food dry, only to find the apartment building's main entrance locked tight despite my repeated calls. Because of this, I started hating the faceless customer who ordered delivery at such an inconvenient time. And then there was the root of all this: Dad. The blame shifted to him—the one who told me it was nearby, told me to save on delivery fees, and sent his pretty daughter out to deliver snacks. ...If he doesn't give me a decent allowance this time, I’m going on a boycott for a few days.
"...Oh, it opened."
I’d tried calling a second time, wondering if he’d just stepped into the bathroom. The response was slow, but just as I was about to pull out my phone, the door clicked open. Come to think of it, the amount of food seemed a bit much for one person. If there were two people, couldn't the other one have opened the door? Or was he just a common pig? Drinking alone? I grumbled at the world while climbing the stairs.
And then, standing in front of room 205, I came face-to-face with the source of all my misery.
"...Uh, sorry. I was washing up..."
"...Oh, no, it's fine..."
It was an adult man wearing nothing but loose training pants that looked like pajamas. "It seems like it’s raining outside."
"...Yes. A little..."
He was reasonably handsome, with a reasonably good body. His skin wasn't wet from water, but from sweat—he looked less like a man who’d just finished a shower and more like one who’d been working out intensely. And... well, the front of his pants was bulging noticeably. If you had even a shred of common sense, it didn't look like he’d rushed out of the shower to grab a delivery; it looked like he’d just finished having intense sex and had scrambled to the door. That kind of man.
"...E-enjoy your meal..."
"...Thank you."
Wow. Just wow. I’d heard stories, but I never thought I’d actually see something like this while working delivery. Feeling embarrassed, I quickly averted my gaze, and the door slammed shut as if telling me to get lost now that the food was delivered.
"......"
I wondered if I might hear something strange from inside. Before leaving, I pressed my ear against the door for a second. But all I heard was the click of the inner door closing. After that, there was nothing.
Thud. I set the bag on the table and headed back toward the bed. It would probably get cold if I waited too long, but... whatever. It’s not like I wanted to eat this kind of stuff anyway.
"...You should've put on some proper clothes before going out."
"I had pants on. Why?"
"...The delivery person. She was... a woman."
"So?"
"...Because she's a woman. Yeah."
"So what if she's a woman? It's not like I'm ever going to see her again."
"...Still, she's a woman."
I couldn't fathom what the big deal was about her being a woman. I gave a dry laugh at Lee Hayoon, who was peeking out from under the blanket, and took off the pants I’d hurriedly put on. My eyes fell on the condom, which had ripped right below the glans from the friction of the pants. ...Jiyoon might be different, but Hayoon hadn't given me permission for internal ejaculation yet.
It was a hassle, but I peeled off the condom, slick with all sorts of fluids, and tossed it next to the bag. I put on a new one and approached Lee Hayoon. There were about six condoms already filled with jelly-like semen, plus the one that ripped during sex, and the one I’d just thrown away—eight in total. My head felt a bit fuzzy from having sex for over an hour, but... she kept drawing a V-shape with her own fingers, spreading her labia to show me her dripping, swollen opening. I couldn't possibly rest.
"What if, just what if the woman actually took your number?"
"I wouldn't give it to her. Besides, not many people know my number."
"...Who knows it?"
"You, Hayoon. The Academy principal. ...Oh, and Jiyoon, I guess."
"..."
"...What are you doing? Suddenly."
I’d tried to pull the blanket off to keep going, to keep thrusting into her cervix like before, but Hayoon was clutching the blanket so tightly I couldn't get it down.
"Hey, Woojin."
"Yeah."
"Jiyoon..., ...you know."
"...Yeah."
"..."
"..."
"...Are you very close with her?"
"...Am I close with her?"
She asked the question with such profound meaning, as if she wouldn't let go until I answered.
"Well. I suppose we're close?"
"...How close?"
"Very. She doesn't have any friends, you see."
"...Neither do you."
"I just choose not to make any."
"...Hmm."
"So, why are you asking that all of a sudden?"
"...J-just because..."
Even with my head swimming from the excitement, a thought flickered: *Could she have figured out our secret relationship?* But even the worst-case scenario was just that—a suspicion. She didn't know how far we’d gone; she just suspected that Jiyoon and I might have done something alone together. That was all.
I was secretly having internal-ejaculation sex with her younger sister while dating Lee Hayoon; if she knew everything, she wouldn't be acting this kind. There was only one way she could know: if Lee Jiyoon told her everything herself. Unless Jiyoon had truly lost her mind, she wouldn't have spilled the beans. So, well... at most, she was just annoyed that I was close to her sister, not just her. In other words, jealousy. A small, petty jealousy directed at her own sister.
"..."
Since this was an emotion Lee Hayoon had never felt before, I realized that if I played my cards right, I could use it to my advantage.
"...Why? Are you... jealous that I'm with Jiyoon?"
"...! I-it's not that I'm jealous... I was just wondering how close you were..."
Instead of the "just because" excuse she’d used earlier, she revealed her obvious inner thoughts. "Hayoon."
"..."
"Lee Hayoon."
"...W-why, why..."
"If you don't like me being close to Jiyoon, just say so honestly."
"..."
"Then I'll keep a reasonable distance from her."
"..."
And then, I’d tell her I’d distance myself from Jiyoon. That to me, she was more precious than Jiyoon. I offered her a sense of superiority with a sweet, hollow lie, crafted in a low, calm voice. Jealousy—when I’m the one being jealous of others, like Hayoon is now, it might look a bit pathetic, but...
"...Or what, should I kiss you in front of Jiyoon?"
"K-kiss... is... uh, um..."
When I’m in a situation where someone else is jealous of me, it feels incredibly good. Like this. Right now.
"...I-I'd like it if you kept a little distance..."
"Just a little?"
"...Yeah."
"How much, specifically?"
"...Just enough to play games together, really...?"
"...What about PC bangs? Should I not go?"
"Yeah... I don't like seeing you and Jiyoon alone together..."
"...Why? Are you afraid I'll do something strange with her?"
"It's not that..."
Lee Hayoon, who had been playing it off as pure curiosity until a moment ago, crawled further under the blanket to hide her face. Without even realizing it, she whispered:
"I'm afraid Jiyoon will do something strange to you..."
"..."
"She hasn't even had any female friends until now, so..."
"..."
"I'm afraid she might... feel strange feelings for you..."
"..."
...She had said it herself, without anyone forcing her. She was currently suspecting her own younger sister, and she’d let out an answer with that exact nuance.
*****
...She's late. Lee Hayoon.
"......"
Aren't they washing up together right about now? Ah, maybe they got turned on while washing and did it again. Seo Woojin was definitely like that when he washed with me, so wouldn't he do the same with Lee Hayoon? Of course, Hayoon is a bit... lacking, so maybe he didn't get as turned on and just washed quietly. They wouldn't have the luxury of using a condom, so maybe he just did it with his mouth. As for using her breasts... my sister's are a size smaller than mine. And she's too much of a coward to allow raw sex, so that wouldn't happen.
...Anyway, good for you, sister. Having sex to your heart's content with a boyfriend who has a big dick, without even having to worry about who's watching. I had to use pathetic excuses like PC bangs just to have a quick session with Seo Woojin behind your back.
"......"
Still, it's fine. Lee Hayoon hasn't had sex at the Academy yet, has she? Some dark, secluded warehouse where people rarely go, or maybe the infirmary itself. ...Anyway, I just sleep during lecture classes. I skip them by making excuses like menstrual cramps that even Seo Woojin finds hard to treat, and during that time, I cover every corner of Seo Woojin's memories with my scent, one step at a time...
> 12:40 PM.
> She arrived much earlier than when I was granted internal ejaculation.
> As expected, my sister just washed her body when she showered.
I sneered gloomily as I heard the front door open. I’d been staring at the game result screen with the word 'DEFEAT' written in large letters, but I pressed the power button on the computer and stood up. ...Why am I even doing this? Lee Hayoon is a fool who hasn't even guessed what kind of relationship I have with Seo Woojin. She's such a fool that she once asked me in all seriousness if I was a lesbian. Even if I provoked her right in front of her eyes, she wouldn't understand, would she?
"I've brought you home, so I'll be going now."
"Ah, thank you."
As soon as I opened the door, I saw two people standing in the entryway. One was Lee Hayoon, wearing a grey hoodie with the zipper half-down. And the other was Seo Woojin, one shoulder slightly damp from the rain.
"..."
So it had been raining outside. I crossed my arms under my chest and stared intently at Seo Woojin. I didn't expect him to greet me first. Since Lee Hayoon was right there, I thought a simple eye contact, like cats do, would be enough. But he glanced at my face, then immediately looked away and tenderly stroked my sister's hair.
...As if he had no interest in me, the one he’d even told he liked when my sister wasn't around. Rather, as if he cared for my sister even more.
"Ugh... I just dried it, why are you stroking it like that..."
"You're going to sleep soon anyway."
"Still..."
"Anyway, I'm going. I'm sleepy too."
"H-hey, Woojin."
"Yes?"
"Before you go, um..."
"...Ah."
...When he said he was going home, Lee Hayoon grabbed his clothes and pulled him close. Seo Woojin looked at her for a moment. And still. Without even glancing at me.
"...Chup, eub..., peuhap..."
He kissed Lee Hayoon, who was cutely standing on her tiptoes. ...It was long enough that I started to think, *isn't this kiss a bit too long?* Right in front of my eyes. For a long time.
"......The taste, it changed..."
"We brushed our teeth together earlier. It must be the toothpaste."
"Hehe... now our tongues taste the same."
"...It'll change again by tomorrow anyway."
My sister's lively voice. Seo Woojin's calm voice. ...I let out a sigh small enough to be buried by them and silently took out some barley tea from the fridge and drank it.
"..."
It was ridiculous to see why my sister was doing such things with Seo Woojin right in front of me, and because of that, it was also a little irritating.
