My Sister Would Probably Love This (5)
What's the greatest luxury a man gets to enjoy just for being born one?
Driving around in a car worth several million dollars? Wearing a watch that costs as much as a few apartments? A house no ordinary person could even picture?
No. You don't even have to be a man for any of that. Those are dreams you can buy, so long as the money's there. Set aside everything you can solve by throwing cash at it. A man. The greatest luxury only a man can taste. Limit the question to sex and sit with it, and the answers come spilling out faster than you'd think.
"Fuck… it's so fishy…. Mmph…. And kind of bitter…. A little sweet, though…."
"I'll get you a tissue. Spit it out. Don't force yourself to swallow."
"…It's fine. …Mmph. If it were my sister, she'd gulp the whole thing down and love it…. She'd probably lick you clean and whine for more…."
Taking a woman other men are only permitted to revere from a distance, and training her exactly to my taste. Making a woman who usually wears nothing but a lukewarm, nothing-interests-me face show me another expression—and only in front of me. Breaking that lofty pride completely, thoroughly, until she's wagging her tail beneath me.
Born a man, could I ever experience anything more electric than this?
…Hard to say. I don't think it's possible.
"Want me to get you some water? You should at least rinse your mouth."
"…Mouthwash. You got any?"
"I do. In the bathroom."
"…Is it bitter?"
"Suit yourself."
Lee Jiyoon, forever dragging her sister in as an excuse while she hurries to fill her own hunger. While she wobbles off toward the bathroom, I look down at my cock, tacky and slick with spit. I'd been buried in something warm the whole time before I pulled out, so the chill of the air is the least of it.
…When I came as much as I wanted inside her mouth earlier, I definitely felt something hit my cock hard. Looking now, there's nothing on it. Nothing but her spit. She complained endlessly about how fishy it tasted, and all the while she'd been cleaning me off with real dedication. That part is almost endearing. The other part is that my cock is so hard I can barely stand it.
The way I feel right now, I want to quit playing along—the nice guy, the guy who doesn't notice—and be done with it. I want to fuck Lee Jiyoon all night and simply not show up for work. Late in the afternoon, her barely awake and whining what if my sister finds out, and me driving I love you into her ear over and over until it's branded into her brain. I want to have sex all day.
But if I did that, the odds of losing Lee Hayun would be too high. Fantasy is only fantasy. I choke down the cold water I just took from the fridge and endure it.
Lee Hayun. Lee Jiyoon. One of them isn't in my original memories, and still she's a hero with a promising future. The other climbs to an extraordinary place even in those memories. And on top of that, they're sisters. Where else am I going to find women like this? So no gambling. Better to keep the stance I have now. Jiyoon coming on strong under the cover of her sister is cute, I'll give her that. All I can do is watch, and hold.
"…Hey."
"Oh, you done?"
"…Seo Woojin, why do you buy mouthwash like some old man? …Tastes like shit."
"It's just mouthwash. What's with you all of a sudden?"
"There are plenty of fresh ones…. This just burns and that's it…."
"…I'll pick some up next time. Something fresh."
"…Lime."
"Yeah. Yeah."
Is she already planning to come back to my place and suck me off plenty next time, too? I fold the thought away and walk over to her. She'd bitten my underwear in her teeth and dragged it down earlier, so I look a little ridiculous. Even so, I have no intention of pulling it back up over the base of my cock, the fabric stretched tight where it's pinned underneath.
That girl. Pretending she isn't looking while her eyes keep flicking down. And every time my cock twitches, her shoulders jump, just barely—because she's insanely turned on. From where I'm standing, watching nothing but her face, there's no way I'd miss it. The way she tidies her gaze afterward, still convinced she hasn't been caught, is enough to drive me crazy on its own.
"Then should we practice something else?"
"…Something else…?"
"…Teasing. You said it'd be good to practice it at least once, right?"
"Ah. Mm."
Every time she speaks, a faint mint drifts off her. For no particular reason I stroke her hair, then seize one wrist tight. Paler than I expected. Thinner than I expected. Cooler to the touch than I expected, too. And the texture—genuinely soft. I want to rub my cock all over it.
Carrying every one of those thoughts, I take her to the bed and carefully tug at Lee Jiyoon, who is still stiff and hesitating.
"…Come up a little more. Don't just sit there."
So she can settle astride my thighs, where I'm perched on the edge of the bed.
"…If I come up any farther… it'll, it'll touch me."
"What will?"
"…Your dick. Idiot. You don't even know that?"
"You had it in your mouth a minute ago, and now you're embarrassed it might touch your navel and your stomach?"
"I-I'm not embarrassed…! It's dirty from the spit…."
"…."
"…Forget it. If Lee Hayun's that much of a pervert, she'd be happy to grind on it…."
I smile, bright and easy, the way you smile at a child who hasn't been dirtied by the world yet, and wrap an arm around her waist. The muscles in my face pull, and it's a little tiring, but from the way she usually reacts, she likes this sort of thing.
"…Ah, seriously…. My spit's all over it…."
"…If you hate it that much, want me to put a condom on?"
"…It's already all over it anyway…."
In the end, even with my glans pressed hard into her navel, she comes closer. Closer. Closer still, near enough that I can hear her swallow, gulp after gulp, wearing a bored face as if none of it matters, staring straight at me. Yeah. It's definitely getting to her.
"…Anyway, what are we supposed to do from here?"
"Practice. Teasing practice, like you said."
"That's not what I asked. …I asked what you're going to do in this position."
"…Light kisses on your collarbone and chest. Or I could just grab your ass like this."
"…Just hearing it is pathetic."
"You told me to tease you. What other way is there?"
"Haa…. Forget it. It's my fault for trotting along after you…. You sexually illiterate bastard…."
Has she really lived without even watching porn? How much of this am I supposed to spoon-feed her? Would her sister be satisfied with something that lame?
Jiyoon mutters under her breath, barely loud enough to catch, and fidgets, opening space between us. Then she wipes her lower belly—now a mess of precum—with one hand, hesitates, and turns around. Thanks to that, I take in her back piece by piece. A short white bob that just brushes her shoulders, and because of it, perfectly visible: ears flushed deep red. Fine stray hairs that still haven't dried, from how long I've been tormenting her. Delicate shoulder blades that get my cock hard just by standing out, for no reason at all. A waist I want to seize in both hands even if I never find a reason. And an ass so pale that, for all that she never exercises and only games at home, I want to shove her against a wall and pound her wet and loud.
While I'm staring at all of it and twitching, she glances back and carefully bends her knees. My cock, stiff and fully hard, jabs the small of her back, and she pays it no mind. She presses in. I'm not looking. I'm not looking. As if that's what the motion is saying, she pushes herself deep into my arms.
"How is this any different from before?"
"The direction. Dumbass. …So now, uh…. Do it. Practice."
"…."
"…God, you're so frustrating…."
She keeps flinching her hips, as if the cock against her waist is getting to her. The moment I breathe my voice into her ear, the hand that had been resting quietly on my thigh comes groping toward me. She's fumbling stupidly around the mattress, so I reach out a little and make myself easy to catch, and the hand she drags along ends up past her thigh, and down, against a place wetter than I expected.
"…Why are you this wet."
"D-don't say it out loud! Why would you say that…!"
"I haven't even touched you yet."
"I-if it were my sister, she'd be about this wet…! I matched it to her…!"
While she was sucking me off earlier, her elbow kept jerking now and then. Was she masturbating then? The guess is plausible enough. I let out a thin sigh and slowly draw the fingers she brought there herself farther down. This is still only teasing practice, so I mean to torment her about a knuckle's worth from the entrance. And then, if neither of us can hold out any longer, I could push in to the root, scrape her walls, and let it slide naturally into sex practice. That's probably how it would go.
But a fun idea pops into my head, and I put it into motion at once.
"…Your hands are completely filthy-minded."
"So what."
"I give you an opening and you start groping immediately…. Nnh…."
"…."
"…."
"…."
"…H-hey."
"…."
"…My chest…. …You're not going to touch it?"
"Later."
"…Ah. Okay."
"…."
Is she talking this much because she wants to bury the fact that she was yelling about being embarrassed five seconds ago? At the slightly sulky sound of her voice, a reaction hits me, and for a moment I spill precum in thick pulses against the small of her back. Her thighs loosen just enough to let a hand slip in. A clit so wet I know it the instant I touch it. I don't stop there. Farther down. Around the time my fingertips find a slick slit, I force her tightly shut pussy open with two fingers, spreading it wide. Sloppy technique, the mewling she spills while she's held in my arms—I ignore all of it, and take my time with that soft, wet pussy, unhurried.
"Don't touch it so fast…."
"…."
"It's teasing, so… light, ly…."
With my middle finger, tap, tap. I tap the tip against the pisshole of a Jiyoon who has somehow gone quiet. Around the time her shoulders start to flinch, I go lower, and instead of the pisshole I set my finger against the hole a cock goes into.
"……Nnh…. Ah, there…."
Tight. I thought she was tight the last time we had sex, but this is a fair bit tighter. Which is why, if I forced my cock in here and pounded it, it would feel so good my brain would go numb and burn. And also why, for now, I satisfy myself only by pressing my fingers hard against her entrance.
Teasing practice. Now that I think about it, this is poison for you alone. Me, well—even if it isn't you, I've got plenty of people I can call. There's Hayun. There's Yojora. Han Sua, too. But you.
"……Ah, wai—"
"…."
"Nnh…. …Hk—"
If I send you home without fucking you, who are you going to go to?
"Hff…. Hf…."
CZ? No chance she'd go looking at that rotten face, so I don't worry about him. Then the men left for you… there aren't any, are there? Oh, your fingers? After you've been staring a hole through my cock this whole time. Your fingers? Really?
"…Woojin. Seo Woojin…."
"Yeah."
"I-I'm doing all right, but…."
"…."
"Touch my nipples a little, too…. And my clit… oris……. …Nnh……."
I pull her waist tight with one arm and push one thick finger just a little way into that narrow, narrow hole. Not in a way that feels particularly good. Only far enough that she could never be satisfied.
"……. Nnh…? Nn…?"
"…Hey."
"What now."
"……A little more…. D-deeper…."
"Why?"
"…I'm left hanging…."
"Of course you are. This is teasing practice."
"…."
"If you end up satisfied while we're teasing, that defeats the purpose, doesn't it? You're supposed to be left wanting."
"…."
"…The more you want it now, the better it'll feel later."
I already know exactly what kind of masturbation she usually does, and where her favorite spots are. So I scrape her walls with wet little sounds, avoiding precisely those places.
"…Nnhh…. …Nnh……. Nn…."
"…."
"…There, a little more…. …Ah…."
"…."
"Hk—. …Ah, please…. Just a little…."
"…."
"Fuck…."
"Don't raise your hand. This is teasing practice. …If you get yourself off, what's the point?"
"Then at least my nipples…. Nnh…?"
"No."
"…Ah, seriously…. You piece of… shit…."
It isn't that it feels bad. Strictly speaking, it does feel good. It's just a little short. Really only a little. Enough to drive her insane with the lack.
"Seo Woo, jin…. Just end this…. My sister wouldn't…, …like this kind of thing…."
"A minute ago you said your sister's masturbating was insanely loud."
"That must've been… the kind where she shoves her fingers in to the root…."
"Even then, a finger isn't going deeper than a cock."
"Her taste must be shallow places…. …Nnh…. Shallow places…."
"When she has sex with me she keeps lifting her hips. Because she wants it driven in deeper."
"……My sister, too…."
"Your sister, too?"
"N-no. …Shut up."
"…."
I can roughly tell what she was about to say. To the end, I pretend I don't know. Pretend I don't notice. I keep going with my lips against her shoulder. No—closer to torture than a caress. She's trapped in a pleasure that almost lets her come, and still won't. Even so, watching is fun enough that I don't mind. Nipples standing stiff without ever quite reaching the peak, nothing but slick dripping from below. Hot, in its own way.
Anyway, I should start talking soon. Torment her any longer and she might actually freeze to death. Better to end anything at a reasonable line.
"Jiyoon."
"What…, you bastard…."
"Bastard? You're the one who said we should practice teasing."
"So what…! Why are you calling me…."
"A wish. Grant me one wish and I'll stop."
"…A wish?"
"Yeah. Nothing that big."
"Stop stalling and just say it…. Hurry…. Hurry?!?"
Press. Press. Only now do I push lightly near her sweet spot, and I lock an arm around the waist that jerks up, and I go on.
"Hayun. She really hated it when you said you'd help from the side, didn't she?"
"……. …. ……."
"Jiyoon?"
"…Y-yeah…. She did…. ………Hk—."
"…I couldn't say it honestly in front of her. I don't really mind. No—I'd actually like it, wouldn't I?"
"…."
"If you help from the side, I can have even better sex with her."
"…."
"So what I'm saying is… could you persuade her a little?"
"…."
I keep pressing only on her sweet spot. I rub her walls until every ridge of my fingerprint has to be getting through. Beneath her, where she can barely manage a panting voice anymore, my palm is soaked slick, and I go on.
"…Tell her you'll let her have much better sex with her boyfriend."
"…."
"…Jiyoon. Answer."
"…."
"Did you just nod?"
"…."
Drip. Drip. She drools onto her own chest, and I watch the small twitch of her head.
"Yeah. You have to move that big if you want me to see it."
"…."
She nods, unsteady and strengthless, too busy clamping her thighs tight to think about anything else.
"Then, since you granted my wish…."
"……?! …, ……?!?"
"…Hey. You're getting the bed dirty."
"……. ……."
Back flush to my chest, she sprays clear slick across the sheet, across the blanket she never managed to move out from under her ass, and onto the floor beneath it.
"…Hoo. Just stay face-down here for a bit and rest."
"…."
"I'll go get a condom."
"…."
Behind her, busy with nothing but ragged breaths, I let an honest smile surface and slowly got to my feet.
Crazy bitch. Is she actually planning to put on some kind of demonstration right in front of her own sister?
That was the thought I stood up with.
