I Went and Did It (2)
"Oh. Today..."
"......"
"...Foreplay. How you're supposed to do it... that sort of thing."
How do I train Lee Jiyoon to my tastes. How do I fuck her as much as I want. How do I make sure I'm the only one left inside her head.
My smile stayed soft. My thoughts did not. Into ears already packed with nothing but wicked ideas, a voice pickled in embarrassment whispered its way in and lodged there.
Yesterday, on that brief call. I could hear every suspicious rustle on her end, and her voice had gone far sweeter than usual, trembling like sugar as she asked pointless questions — did I like cats, that kind of thing — just to keep hearing me. And through the receiver, quiet little gasps. Heek. Hik. Maybe that was why. The voice murmuring beneath me now sounded several times lewder than before, and my cock was already trying to stand at attention.
"Uh, yesterday it kind of felt like we rushed through it all half-assed... so this time, step by step..."
"Step by step. Meaning we start with that foreplay you mentioned?"
"...Yeah."
I'm going to lose my mind.
A little sister, under the flimsy banner of Sex Practice, teaching her older sister's boyfriend how to touch a woman. Post that on the internet — what the hell is this girl even doing? — and the answer would be painfully obvious. Recommend me some hentai with that exact plot. That kind of reply.
And what was I supposed to do about it, when the heroine of that exact hentai was right in front of me, offering to teach me foreplay from the very first step?
"...Was I weird yesterday?"
"You got worked up and acted like a total amateur, you know...?"
She spat it out in little ticks, then forced a leisurely smirk. Hizuk.
What did like an amateur even mean. That instead of hauling her clothes up however I pleased, pulling my cock out, taking a devoted blowjob, pounding her thighs like an animal — thud, thud — and spurting sticky semen all over that snow-white belly, she wanted me to hesitate like a pathetic moron and act in a way that made her want to explode from frustration?
I didn't get it. Not with an insanely hot little sister right in front of me, wet from doing something bad with her sister's boyfriend behind her sister's back.
No. This is wrong. We should stop here. Pulling that kind of bullshit would be way more fucked up. And this sort of thing probably didn't even match her tastes.
"Like an amateur... I see."
"So today... ah, wait. I prepared something."
She'd been whispering, as if she were worried about the neighbors next door. Then she slipped out of my arms and headed for the computer desk. Beneath the pajamas, hips that felt a lot like Lee Hayun's held my eye for a moment. What pajama-clad Lee Jiyoon rummaged up and gathered into her hands was—
"Why that, right now?"
"...Don't you remember the kiss yesterday?"
A color exactly opposite her white hair. The same color that still faintly lingered underneath, at the roots, like a bridge. A pitch-black cloth mask.
"If I wear this, we can at least practice the timing of a kiss..."
"We have to practice timing too? I already kiss Noona, you know."
"...Sh-shut up. Just do what I say."
Mask covering half her face, Lee Jiyoon settled back beneath me. To practice sex for her sister's sake. To practice foreplay for her sister's sake. She piled on excuse after excuse in her own defense, when the truth was simpler. She wanted to sink all the way into the guilt of it.
"And yesterday you... you only touched my chest for a second, and didn't really do anything else, right...?"
"...Probably. It was roughly like that, yeah?"
"Today... that. ...... ..."
"...What?"
"Y-you can touch it. There."
"......"
"...It'd be good to know, roughly, what foreplay is supposed to feel like, so..."
"......"
See.
Call it Sex Practice. Make the excuse that it's for her sister. Then give permission to touch her pussy. There was only one obvious reason. She wanted to feel good. She wanted to get herself off today, too.
"Of course, um... putting fingers in is forbidden. P-pinching the clit is forbidden. Deliberately fiddling with the hair is forbidden. Keeping going after I say stop is forbidden. Licking is forbidden. And..."
"...Pfft."
Maybe she didn't like that I couldn't hold the laugh in. After rambling on for a good while, Lee Jiyoon tapped my chest with a fist that had no strength behind it.
"Wh-why are you laughing? Don't half-listen. Take it seriously...!"
"If you're going to forbid all of that, wouldn't it be better to just briefly tell me what I am allowed to do, Jiyoon?"
Struck dead center, she went mute on the spot. I was still chuckling above her, playful, when I brushed a fingertip over the button of her pajamas and asked.
"Anyway. We said we'd start with foreplay today, step by step, right?"
"...Yeah."
"Then I'll try it however I want for now. If there's something you don't like, or something I shouldn't do, tell me when it happens."
"...H-however you want...?"
"Remembering every single thing you said I can't do is too much for me. I'm not exactly the brightest."
"......"
A long stretch of eye contact. Then Lee Jiyoon, who hadn't said a word, nodded. Just a little. Up and down.
Idiot.
You don't hand out permission like that so easily. Men in particular love to misread the small things. You might have meant it literally — foreplay, and only however I wanted — but to a man's eyes, it looks like going all the way to sex is fine too. Even if you act like this in front of me, you really shouldn't act like this with other men. CZ, that bastard — was he bewitched by this side of her too?
I brushed a few stray hairs off the bridge of her nose, then slowly began undoing the buttons of her pajamas.
"......"
Her sister's boyfriend's hands, opening every last button. A snow-white, pretty bra, nothing like the plain thing from yesterday. A soft tick as the hook came free, and those yielding breasts laid bare in front of me. A breast that didn't quite fit in one hand, gathered into a full grip as I leaned in and met her lips through the mask.
Lee Jiyoon closed her eyes without a shred of resistance, as if all of it were fine. Instead of bolting in embarrassment, she actually lifted her chin a little. So the kiss could land at a prettier angle. So she could press herself more stickily against my lips, which had only lightly clung through the mask, and fill herself to the brim with her own ugly want.
But then.
"...Five points. Idiot."
"Five points? For what?"
"The foreplay. ......It's a five."
Her lips drew slowly away and spat the words out, blunt, from behind the mask.
"Wh-who likes it when you just grab their chest hard out of nowhere and kiss them?"
"......"
Lee Hayun. And you. Your sister is like that. So are you. Going by reactions alone, neither of you seemed to particularly hate it, so I couldn't understand why both of you insisted, out loud, that you did. Was I supposed to call even this sisterly?
I looked down at her, dissatisfied, and asked it like I was tossing the words away.
"You liked it, though."
"Wh-what?"
"Yesterday too. Today too. You were rubbing your thighs together."
"...Y-you're imagining things. ...Anyway, you should've complimented me. Said I was pretty. Or just kissed until we were both turned on. Something like that..."
"Then I guess I should check."
"...Check what?"
"You already gave me permission to touch your pussy first."
"...W-wait. Seo Woojin, that's—!"
Visibly flustered, she grabbed my forearm tight. I overpowered her hand, a little rough, pinned it to the bed, then seized her sleep pants and dragged them down. Far enough that the waist tie, knotted in a butterfly bow, showed. Far enough that the snow-white panties inside began to show. She thrashed so they wouldn't come off, and still the pants slipped out from under her hips — far enough that I found it. A gray stain, stark against the white, laid bare across the panties.
"What's this, Jiyoon?"
"......"
I could see, with my own eyes, just how wet she'd gotten. Lee Jiyoon couldn't. She could feel it, though. How soaked the panties were. How that would look in the eyes of the opposite sex.
"You said I was imagining it. The thigh-rubbing."
"......"
"You said who likes it when someone just grabs their chest hard out of nowhere and kisses them."
"......"
The mouth that had been chattering until a moment ago — five points, compliments, kisses — clamped shut. The cheeks and ears visible beside the mask flushed red, and she only dodged my gaze, this way and that.
Keeping on tormenting her like this would have been enjoyable in its own way. Honestly, though, any more and my cock felt like it was going to burst.
"...Crazy bitch."
"...Nnh......"
I threw the sweater I'd been wearing onto the floor. In a pitch-black short-sleeve that left the muscle on full display, I lay down beside her and slipped a hand between her thighs.
"...Turn your head. Look at me, Jiyoon."
"...N-no..."
"You said you'd help me practice. Foreplay practice. And Sex Practice."
"...You're just going to tease me...!"
"I won't tease you. I'll only kiss you."
"Then what was all that teasing just now."
"You were cute. That's why."
"...C-cute... Noona's the cute one. What's cute about me..."
"You get this wet from nothing but a kiss, then throw a fit and call it five points, and that's not cute?"
"...Shut up..."
I drew the fingertips resting on her panties slightly outward, and a thin thread stretched between skin and cloth. I pressed around her clit, patting, and listened for a moment to the moans she was trying so hard to hold in. Then I slipped an arm behind her back.
"Mmph.... Mmmph..."
I pulled the panties aside, gave her clit a proper scolding, caught the back of her masked head, and forced our lips together.
"Nngh, nn..."
For now I was doing my best to scold her as gently as I could, the way she liked it. Even so, the stimulation on her clit must have been too much. Her thighs kept trying to close, as if telling me to stop. Now and then her waist twitched upward, so it didn't seem to hurt, or to feel bad. How was I supposed to make her like it more? Thinking that hard was difficult with all the blood rushing to my cock.
With no other choice, I used my leg to force her thighs open and pin them, caught her clit — soaked slick with her own wetness — between my fingers, and rubbed. Again and again.
"Haaah.... Haa.... Haa..."
Lee Jiyoon looked at me with a hazy gaze, as if she were drunk. Hot breath spilled through the mask. Her waist trembled. In less than a minute she was grinding her bangs hard into my chest, and she didn't stop until she'd come, hard.
"Jiyoon."
"Hahk.... Hahk.... ...Wha... whyyy..."
"You're way more sensitive than I thought. Getting off on foreplay from an amateur."
"...I-I told you to shut up..."
All I'd done was figure out her tastes and touch her accordingly. Lee Jiyoon would never know that, not for the rest of her life. The only thing left in her head would be the memory that Seo Woojin's fingers felt incredibly good.
I showed her a sly smile and started on her clit again.
Once. Twice. Three times. Four. Until she got honest. All the way.
"Nngh...?! Nnh......! Nnngh......"
Together with a kiss that had nothing between us but a single mask. Together with my fingers worrying nipples that had already gone completely stiff. A few more touches in the same way, and every time her waist jerked, a small wet spot began to bloom on the sheets. Not a climax fierce enough to squirt — but the love juice that had trickled down must have amounted to about that much.
"Huu..."
"Haah.... Ha.... Stop, stooop......"
After a long kiss I pulled my lips from the mask, soaked now with both our breath and spit. Hazy-eyed, Lee Jiyoon kept repeating it like something broken. Stop. Stop.
I started teasing the sticky flesh around her clit all over again.
"Nnh...? W-wait, what is this......"
Before she could come back to herself — mouth shut, body given over to me — I caught the mask hard between my teeth and dragged it up over her eyes like a blindfold.
"Nngh.... Chup...? Pwahh...?"
So I could kiss her with our tongues mixed.
"Hey, this, the kiss..."
"Getting saliva on it."
"...Ah...?"
"Getting saliva on your tongue. Idiot. You called me an idiot..."
"......"
"...Open your mouth again."
So she couldn't think too deeply. So she couldn't see my face, and the guilt would dull. So that, instead, the taboo of it could be drawn up much higher.
Lee Jiyoon opened her mouth carefully, without any real argument. Against my tongue, pushing between her lips as it pleased, she was cute about it.
"Chu, chu.... Nn, nnmph..."
So she could act spoiled.
