Doing Bad Things
"There. Do I look a little more like Noona now?"
Lee Jiyoon stood in front of me with her hair pulled into a ponytail by a single jet-black tie, smiling awkwardly. Honestly, it was obvious how forced the smile was. Still, maybe because they were sisters, I could almost see Lee Hayun overlapping her—the girl who usually went around glittering with laughter. Judged by looks alone, the only real resemblance was in their eyes.
"You do look a bit like Hayun-noona, I'll give you that."
"Yeah? Then what if I throw in a Woojin~ on top?"
"Don't. You don't sound like her, so just don't."
"...That so? Well, I don't know what Noona's like when it's just the two of you."
What she's like, huh.
Cute as she was, she did strange things because she wanted to be treated like a noona. And yet the moment I stroked her hair and pressed down hard, all the way to the roots, she rubbed her forehead into my chest and twitched again and again, pleased. When the sex ended she got a little sulky and said nothing for about two minutes. One nothing of an I'm sorry melted the grudge, and she grinned all dopey and took the kiss. After the kiss, we had sex until we were cutting it close on time. That wasn't something you could pull off just by deciding to act. And one woman of that type was plenty.
I want to fuck you, Lee Jiyoon. I want to see how you'll react. That's why.
"...Lee Hayun."
Jiyoon was doing her best to imitate her older sister. I stood in front of her and deliberately called Hayun's name. Contradictory as that was.
Truth was, coming this far, I had a pretty good idea of her tastes. Not her own name—called by her sister's, she flinched the instant she heard it. My guess was looking right.
The day we first met, clicking her tongue and spitting something rude while she looked at Hayun, who'd come to the infirmary. When she offered her sister's preferences as payment for the treatment, strangely conscious of me the whole time. At the karaoke room, climbing onto my thigh and pressing down like she was pouncing, even though she didn't have to. And now.
I'd already told her it was fine to do it at my place. I'd asked, over and over, whether she really meant to do it here. Behind her sister's back. In her sister's room. Smiling like her sister, wearing her sister's hairstyle, offering to help me practice in her sister's place.
She could hardly complain if I took it the wrong way.
"...Ah."
I caught her wrist and tipped her onto the bed. Jiyoon let out a short gasp and clamped her mouth shut. I looked down for a moment into those deep-green eyes with nowhere left to go, then pulled the khaki jumper she was wearing up until it half-covered her face. The inside was soft white fleece, so it wouldn't hurt her. With that, I covered her mouth.
"...! ...?!"
And pressed my lips gently against it.
"...! ... ...!"
Skin never touched. Saliva never mixed. Not even our breath mingled. Only our eyes met, endlessly—something crisp and dry that merely resembled a kiss.
Startled, Jiyoon thrashed. I pinned her wrists hard to the bed and kept up that bad little act.
...You wanted to do something bad behind your sister's back too, didn't you, Jiyoon? That's why you insisted on Hayun's room. Am I wrong?
"Mmph...! ...! ..."
I kept the fake kiss going with Jiyoon, who kept dodging my eyes, but only for a moment. Brow furrowed, I carefully wiped my lips with the edge of my palm and pushed myself up. Her face flushed red, she was shoving at me hard with her bare feet.
...That hurt like hell.
"Pwah—! Hk—! Hk—! Wh-what are you doing! You crazy bastard...!"
"What?"
"Th-that was a kiss.... That..."
"We didn't even touch. And you're the one who told me to pounce."
"...Th-that's true, but..."
A moment ago there'd been a faint trace of Hayun about her. One fake kiss, and she was just Jiyoon again—the Jiyoon I heard over Discord when we gamed. I liked this better than watching her force a Hayun act. She probably wanted to be taken while she played her sister. That would be her type.
With her sister's boyfriend. Behind her sister's back. Pretending to be her sister. Doing something bad. Roughly that kind of taste.
...In short, a complete pervert.
"No kissing?"
"...... ...It's fine. But put something in between, like just now.... A real kiss is absolutely not allowed..."
Look at that. She could have just cut it off and told me no. Instead she left herself an opening. Sly about it.
"Then settle it all now. How far is fine, and where it isn't."
"...No sex."
"Isn't that obvious?"
"Y-you never know. Shit..."
Embarrassed to have said it herself, Jiyoon furrowed her brow and thumped my thigh with her foot. I hadn't planned to go that far anyway. I didn't even have a condom. The moment some accident got her pregnant, the whole plan would collapse.
She was supposed to get fucked like a dog by me every night, then spend her days diligently playing the pure little hero. Get pregnant out of nowhere and she wouldn't be able to show her face to those pigs for over a year—not behind some excuse about health problems that wouldn't fool a soul. And then what would be the point of fucking her?
She had to kill villains and get on TV, headline the articles, sit for the occasional interview. I had to read, one by one, the comments of fans losing their minds over the gap—the way she trembled, so unlike herself, and them calling it charm. You, who couldn't care less about those fans. You, sunk deeper into a monstrous cock that wrecked you until you couldn't think than into the fans cheering you to hang in there. I had to fuck you until the bed was covered in irregular stains of your slick. Only then would the plan be complete.
"And? That's all? Just no sex?"
"Wh-what do you mean, and?"
"I told you. Where am I not allowed."
Still pinning her wrists hard to the bed, I asked, and Jiyoon's throat bobbed. What came out was—
"...As long as we don't... have sex.... Not really..."
A mutter with plenty of room to interpret.
"I said I'd help you practice pouncing on Noona, so..."
A mutter that could only be read one way.
"I-it's not like touching a little wears anything out."
"......"
"And you're Noona's boyfriend, so you wouldn't have any 'ulterior motives'..."
"......"
"Since we're... friends?"
"......"
"...You wouldn't think anything weird, right? It's just touching. Right?"
Impossible to parse by any ordinary sense. Packed with nothing but the urge to indulge her own tastes. A solid lump of excuses.
"...So as long as we don't have sex, it's fine?"
"...Yeah."
"And I can put my hands on your body the way I really would with Hayun-noona."
"...But you still have to keep the line, okay? You know that?"
"The line? Put plainly, that means I can touch your chest, doesn't it?"
"Th-that's true, but...! That......"
When I slipped into that mutter—
"...You can touch, but don't pinch, or twist, or squeeze.... Don't do that..."
An even smaller whisper spread across Lee Hayun's bed. With her wrists pinned under mine, she couldn't even hide the face gone bright red. A whisper, and another.
I took hold of her collar again and went on.
"If there's something you don't like, kick me like before. It hurt like hell."
"...It hurt?"
"You drove your heel into me. How would that not hurt?"
"...I'll be careful. Earlier I was, um, startled because it was so sudden..."
"Forget it. Just hit me hard. If I don't catch on, you'll be the one frustrated."
"......"
"...Here. Bite this."
"......"
Jiyoon gave a small nod and carefully bit down on the khaki jumper I brought to her lips. I looked into those deep-green eyes, identical between the sisters, and once again—with the crisp fabric between us—pressed my lips to hers.
"...... ..."
Not biting. Not mixing tongues. Not nipping. Doing nothing at all. A fake kiss that was only the performance of one.
Jiyoon, who until a moment ago had been kicking hard and telling me not to kiss her, now lay still without a shred of resistance, staring blankly up at my face. All she did was rub together the thighs resting on the bed, twitching and twitching.
Her sister's just the excuse. She's only feeding her own selfish wants. Well, fine. Better this than holding in a laugh at that awkward acting. Just stay like that.
"...Hoo..."
"......"
I peeled my lips from the khaki jumper they'd been stuck to, drew in a short breath, and let it out soft. Her coat had grown a little warm from how closely the two of us had been pressed together. Looking down at it, I gathered Jiyoon's wrists above her head and pinned them tight.
"...Looking at you like this, I think your chest is bigger than Noona's. Am I right?"
"...Talk politely. I'm standing in for Noona right now..."
"Am I right."
"...Mine is a little bigger, but.... Mmph..."
Jiyoon muttered as if embarrassed. I overlapped our lips again and set one palm on the plain white T-shirt, nothing on it but a crude print. The moment I touched her, her waist flinched and tensed. I'd only swept upward a little, and the ribs beneath the wrists I held so obediently writhed. Past those, slowly, I drew my hand up until my thumb sank into the breast that rose, indecent and full.
"...Pwah.... Hey, Seo Woojin..."
"What."
"S-say something while you do it..."
"Say what? I have been."
"...Like, I can't hold back anymore, Noona. ...Something like that. You know...!"
"......"
"Right now it just feels like we're... having... s-sex..."
"...I get roughly what you're after, but this isn't a romance novel. What kind of creepy line is that."
"...I-is it that weird?"
"Yeah. It's weird."
"...I don't think reality would be all that different..."
"It is. Dumbass. For instance..."
On the T-shirt, I raked the soft bra caught on my fingertips upward along with the white shirt, and went on.
"...I don't really know either."
"...Knew it. ...Virgin bastard..."
So that Jiyoon, wound tight, could loosen up.
"You don't usually talk like that."
"Pfft.... Did virgin bastard get under your skin...?"
"Yeah. From someone else, maybe. Hearing it from you—who doesn't even have a guy friend, hell, who doesn't have a friend at all—is a bit much."
"...S-so what? If it bothers you, call me a virgin bitch too."
"Virgin bitch."
"...Virgin.... ... ...bastard."
Her pale breasts fully bared, her cherry-blossom nipples flicked against by my fingers, and still—
"Virgin bitch."
"Virgin.... Nnh...... bas-tard..."
So that instead of telling me to stop, she could snap back at me as if that much didn't particularly matter.
"...Keep going, then. I can take the label off whenever I want. You can't."
"...So what. I even hinted that Noona likes rape play, and you still couldn't fuck her, you pathetic coward..."
"I can play along with that later."
"Excuses.... ...I get it. You're like this because you don't have the confidence, right?"
"Confidence?"
"You pounced on Noona hard, the way I told you to, and you're scared she won't like it that much."
"......"
"I'm right. Seo Woojin, you... ...ah. ...Smaller than I thought, huh...?"
So that, riding the mood, she would make one small slip.
"Then want to take a look?"
"...L-look at what...?"
So that, using her own words as the excuse, the practice could get a little more shameful.
"What kind of cock your sister's going to get fucked by, later."
"......"
"Want to see?"
So that every word she had just spat would come back around as a shackle. I steered the talk there.
"......"
"......"
Maybe that was why. Instead of an answer—take it off, don't take it off—what reached me first was gulp, gulp. The wet scrape of Jiyoon's throat as she swallowed, her mouth watering.
