Those Who Say "Just You Wait"
"Are you crazy, Noona? What if someone sees?"
"Well, you're the one who said it! That we could touch... or do even more than that..."
Yeo-eun offered a weak excuse in a hushed whisper.
"So you went ahead and took off your panties just because I said that?"
"Yeah... pretty much."
Passing the blame onto me, as usual. Just how much had she been anticipating this to go and pull her underwear off in advance?
"Is that so? Then that means you were expecting something like this, right?"
I slipped my hand back under her dress. Unable to see in the dim, cramped coin karaoke booth, I relied entirely on the sensation in my fingertips to seek out her slit. I gently raked over the soft fuzz of her pubic hair before venturing deeper. Soon enough, my fingers met flesh that was noticeably softer and tenderer than the rest.
"Spread your legs a bit wider."
"Like... like this?"
"Yeah. And make sure you keep the window covered."
Yeo-eun turned her head to check the position of the small window set into the booth door, then pressed her back firmly against the glass, completely blocking any view from the corridor. Now, even if someone happened to walk past, there was no way they could peer inside.
"Dry, isn't it?"
Pressing my palm flat against her lower abdomen, I cupped her pussy with my entire hand. While a woman's anatomy couldn't be gripped like a man's cock, the sensation was remarkably similar. I kneaded the plump, plush mound of her pussy like a lump of soft dough.
"Hngh... Jeongseo..."
"Strange. I was certain you'd be dripping wet by now."
"I'm not... Do you really think I just leak all over the place anywhere I go?"
She denied it with trembling eyes. A total lie.

With her face flushed crimson and wearing an expression like that, it was impossible to believe a single word. Of course, her blush might have been triggered by my direct touch, but somehow I suspected she had been aroused for quite some time. After all, I had clearly caught a glimpse of her damp panties back at the clothing store. I decided to make sure.
"Oh, really?"
Using my fingers, I spread her labia apart, then hooked my middle finger and dipped it lightly between her folds. Squish. It was utterly slick. Thick, sticky arousal coated my finger instantly.
"Then what's this?"
"Ah..."
She looked composed enough on the outside, but inside, she was soaking wet.
"You just lied to me, didn't you?"
"N-no, I wasn't trying to lie... I was just embarrassed, okay?"
As I withdrew my hand, the fabric of her one-piece dress fell back down, concealing her crotch. How annoying. Rustle.
"Jeongseo?"
"Hold this."
Gathering the hem of her dress, I hoisted it up and shoved it into her hands, leaving her lower body completely bare. Still, something felt lacking. Tap, tap. I nudged her feet with mine.
"Hm?"
"Spread them wider. More."
The karaoke booth was terribly cramped. Yeo-eun had barely parted her thighs before her feet hit both side walls. Stepping back slightly, I took in her entire figure.

"Is this good?"
"Still missing something."
"I can't spread them any wider!"
"Not that. Here."
The dress she wore featured a plunging V-neck. Tugging the front open to either side exposed her bra-clad breasts. Reaching in, I scooped her voluptuous breasts out of the cups entirely.
"There."
"Ugh... this is a little humiliating, you know?"
Stepping back as far as the small room allowed, I inspected her whole appearance once more. It was a ridiculous, perverted display. Even Yeo-eun felt the shame of it, keeping her head lowered in embarrassment.
"Noona."
Closing the distance again, I whispered softly into her ear.
"Yeah?"
"Endure it well. It might get a bit rough."
"Huh? What's going to be rough—hyih?"
"Tsk! If you let go of your skirt, I'll be really mad. And I won't do anything like this for you ever again."
"O-okay. I'll hold it tight. Haaahn..."
I rubbed her pussy with one hand. Gently at first, cupping her thick mons pubis beneath my palm and applying a subtle, steady pressure.
"Jeongseo... touch my boobs... touch my breasts too."
Her embarrassment didn't last long; she was already leaning into the sensation and reveling in my touch.
"Like this?"
"A little harder..."
With my free hand, I squeezed her breast firmly. At the same time, I leaned more weight into the hand working over her cunt.
"Haaah... mmmh. It feels so good."
"Good?"
"Yeah... so good."
"I'll make you feel even better."
I began to rub along the seam between her thighs. Leaning forward toward her chest, positioned at just the right height, I pressed my lips to her stiffened nipple. Chuu, slurp— A light kiss gave way to suction as I drew it greedily into my mouth.
"Mmmn... haah."
Yeo-eun twitched and shivered under the onslaught. Gauging her reactions, I hooked my middle finger once more and grazed the tip against the entrance of her cunt. Squish, squelch.
Amid the upbeat medley blasting from the karaoke machine, an intensely lewd sound bled through. The more my finger wriggled and teased, the hotter her flesh grew, radiating a feverish warmth coated in slick moisture.
"Haaah. Jeongseo... put it in. Inside... haht. Poke inside too..."
Even while working my fingers eagerly against her, I refused to slip them inside. Kept lingering only at the rim, Yeo-eun couldn't bear the torment any longer and begged for penetration.
"No."
Even though I had cleaned my hands with sanitizer, I had no intention of sticking them in.
"Ah, whyyy? Please! It's not enough! Hnghh. Just shove them in!"
"No way. I couldn't wash my hands properly."
Yeo-eun pleaded desperately, though hygiene was merely my excuse. Making her squirm in sheer frustration was infinitely more entertaining. Watching her bite her lip in agonizing impatience, I continued to mercilessly tease only the exterior. The more she writhed in torment, the more my lingering irritation subsided.
"Haah... haah... hnnngh."
Her breathing turned ragged. Even though she was merely standing there, offering her body up to me, she panted as if running a marathon.
"Just a little... Jeongseo, just a little more..."
Observing her fevered state, I dipped my head down again, this time latching onto her untouched nipple while rubbing her pussy at an accelerated pace.
"Hnnngh! Haaahng...♡"
Yeo-eun went momentarily rigid, letting loose a syrupy, helpless moan. Just from the friction on her outer lips, she seemed to have tumbled into a modest orgasm.
"Hngh... Jeongseo. That's enough now. Thank you..."
"Hm? Thank me for what?"
"I mean... didn't you do this to make me feel good?"
Releasing her nipple from my mouth, I met her gaze. My hand pressed against her cunt hadn't stopped moving.
"Ngh. Stop. Haaang. You can stop now. I'm satisfied."
"Noona."
Yeo-eun lowered one hand, looking as though she intended to grab my wrist.
"Is it over just because you're satisfied?"
"Huh? Ah... sorry. Should I suck your dick?"
If she had offered that earlier, I might have gone a little easier on her. But having indulged solely in her own pleasure before finally bothering to read my mood, it was far too late.
"No, forget that. Didn't I tell you to endure it well? And didn't I tell you not to let go of your skirt?"
"Huh? Didn't I endure it? I stayed totally still..."
"I'm not finished yet. Grab your skirt again. I'll let it slide just this once."
Sensing something was amiss, Yeo-eun tried to shift her posture. I planted my hand firmly against one of her breasts, pinning her back against the door so she couldn't pull away, fixing her with a stern glare.
"You promised not to use your strength on me. Remember?"
"No, wait, it's not that... ngh."
"It might get a little rough. This is your punishment, so you'd better endure it properly. Understood?"
Ignoring whatever protest she was about to mount, I set my hands in motion.
"Jeongseo. Jeongseo? Wait... what are you going to do?"
Anxiety crept into her tone—naturally, since both of my hands had descended below her waist. With one palm, I pressed down firmly against her lower belly, applying extra force with my thumb just above her clitoral hood. The engorged clitoris peeked right out from beneath its sheath.
"Haaah! No! I'm way too sensitive right now! Jeongseo?"
With my other hand, I launched a focused assault on that exposed bud. Smearing the slick juices she had secreted all over it, I rubbed relentlessly, zeroing in exclusively on her swollen clitoris.
"Hyiiik?! I'm really sensitive! Stop!"
My fingers sped up. Even with her arousal acting as lubricant, moving this roughly on an overstimulated nub was bound to teeter on pain.
"You can't use your strength, Noona. You promised. Stay still."
Her hands twitched instinctively.
"If you can't handle this, I'll never do anything like this again. You're the one who cheated first, so take it."
At my warning, she merely clenched her fists tight, struggling to bear it. Confirming that she had no choice but to endure, I bent my head down again and captured her nipple with my mouth. Sucking it deep, I brought my front teeth against the sensitive bud.
"Haaahk! Mmph!"
I bit down. Not hard enough to cause serious pain, but firm enough to sting. Clamping her nipple gently between my teeth, I pulled my head back slowly, stretching the flesh. At the same time, my other fingers drummed furiously over her clitoris like someone mashing buttons on an arcade cabinet.
"Stop! Jeongseo, please stop... stop! It's too much! Hic... sniff. I was wrong, okay?!"
Ignoring her tearful pleas, I remained thoroughly absorbed in my task, lightly gnawing on her nipple with rhythmic, nibbling bites.
"Aaaahn! No! Seriously... stop! I feel like I'm gonna pee!"
Spitting her nipple out, I lifted my gaze. Tears brimmed in the corners of Yeo-eun's eyes, her face completely unraveling in disheveled distress. Only then did the lingering pique finally dissipate, calming the impulse inside me.
"That's what you get for playing dirty in the game."
"I'm sorry! I said I'm sorry! Hic... I was wrong, so seriously, please just stop!"
"It's fine. I'm pretty much over it now."
When I offered a small smile, a look of profound relief washed over her features.
"Yeah... haah... So it's over, right?"
Yeo-eun exhaled a shuddering breath. Most of this world's crises arise from letting one's guard down, yet she had relaxed far too soon.
Squeeze. I pinched her clitoral pearl tightly between my thumb and index finger.
"Eeek?!"
Her eyes flew wide. Grinning, I gave that pinched bead a sharp twist.
"Aaaaaaargh! You crazy... you little—!"
Yeo-eun swallowed back the curse and shriek tearing from her throat. Watching her writhe, I tightened my grip just a fraction more, tugging gently on her twisted clitoris.
"It hurts! Stop! Seriously, stop! Hwoooohk?!"
Her back peeled away from the door. Letting out a bizarre shriek, she bent at the waist and collapsed her entire weight against me. Thud. The sudden collision knocked my hand free. Slumped against my shoulder, her back heaved with ragged breaths.
"Noona. Noona? You okay?"
"Haah... haaah... haah."
After a moment, she managed to catch her breath and slowly raised her head.
"Okay? Do I look okay?! You... I literally told you I was sensitive right now!"
Tears still glistened in the corners of her eyes, and her face was burning bright red.
"Are you mad? You're the one who wronged me first, so don't get angry."
Hastily gathering her clothes, Yeo-eun glared at me in sheer disbelief.
"I'm going to the restroom first. And you, Noh Jungseo..."
"Sure. Go ahead. I think I'll go too."
She really must have needed the bathroom badly. Stuffing her exposed breasts back into her bra with frantic haste, she dusted off her skirt in sharp, irritated pats.
"You just wait."
Reaching for the doorknob, she swung the door open. As she stepped out, I tossed a parting shot at her back.
"You know, people who say 'just you wait' are never actually scary."
"..."
Hearing that, her step faltered for a fraction of a second. But without offering a reply, she slipped through the door. Staring at her silent retreating back, an ominous prickle washed over me. Perhaps that last line was one taunt too many.
