Practice Sex (2)
Was there a sound in the world more obscene than this?
"Hoo..."
"Heh... hehh..."
I had buried the head of my cock as deep into her cunt as I pleased, forehead pressed to a woman who couldn't get a word out but had very clearly just come, and now the condom stretched drum-tight around a heavy flood of semen let out a thick, wet glug. Glug, glug. Was there a sound more obscene than that?
"...Stick your tongue out. This way."
"...Bleh..."
A kiss I'd grown far too used to. She obeyed without a fight, so I caught both of Lee Jiyoon's wrists in one hand and pinned them hard into the pillow. Holing up at home to play nothing but shooters had left her pale as paper. Her wrists were slender in a way a man's aren't, and I worried, just a little, that too much force might actually snap them. She could have thrashed if it hurt. That she simply lay there and let herself be held down was almost commendable.
...Maybe that was why. The more I touched those wrists, the worse my thoughts turned.
Back when you could barely catch her on TV, that girl had scowled so fiercely at the camera. Lying on this bed and looking up at me, she could barely keep her eyes open for the pleasure. I wanted more of this face. I wanted to drink in more of it. I wanted to break her as thoroughly as I possibly could.
"...You okay? Feels like I came a lot harder than usual..."
"...S-so it... must've felt good."
"Didn't you tell me not to ask a girl that kind of thing?"
"..."
"...What. Curious? You want to hear it?"
"...Asshole. Just get lost..."
"It was good. Honestly... way better than with Hayun-noona."
"..."
"...I'll change the condom first."
"...Hey, slow d—"
I fed her only the lines she'd want to hear, then dragged my cock out, scraping along the hot walls on the way. That alone was enough to shut Lee Jiyoon up and set her clenching down in tight little pulses; she'd clearly come again, lightly. I had too much left to do to get hung up on something like that. There were plenty of condoms left anyway. No point getting excited over one small thing, right?
How to put it... Ah. Right. I had to keep driving into her until her head went white and she slipped. Until, in this sordid little arrangement Lee Hayun knew nothing about, the upper hand was mine for good. And after that, I could train Lee Jiyoon to my own taste, couldn't I. Well. For now it was all just a dream. Still, what was the harm in dreaming one.
"Where should I put this? You want it?"
"Wh-why would you give that to me...! You perverted bastard...!"
"Just in case. You might use it when you practice."
"...Practice?"
"Yeah. Practicing things Hayun-noona would like."
"......"
"If you don't need it, I'll just throw it out."
"...Give it. Give it here. For now..."
Packed so full of semen it sagged at the tip like a little water balloon, the condom came off in my hand, and I passed it to Lee Jiyoon. The weight must have startled her the instant she took it; she bit her lower lip, cute enough that I wanted a photo. I didn't let it show. I went to the head of the bed, where she'd tossed the box a moment ago, and picked out a fresh one.
I would have liked to make her clean my cock while I was at it, but I let that pass. From the way she reacted, she loved kissing. A lot. I didn't want some strange taste in my mouth every time I tangled tongues with Lee Jiyoon, so the heavy stuff could wait until the end. If I was ever going to make her deepthroat me, better to stack the experience properly.
"Hoo... how should we do it this time? Want to practice pulling hair? From behind?"
Sniff. Sniff. While I rolled the new condom on, Lee Jiyoon lay on the bed and cautiously smelled the used one. I pushed my erect cock toward her face as I asked, and the eyes that had been drifting shut, hazy with it, widened a little.
Lee Hayun and Lee Jiyoon. Two people who, from the outside, hardly looked related at all—and the one thing they shared. Those deep green eyes. Because of them, the reality that I was taking turns fucking actual sisters landed on me all at once, and my cock stiffened even harder.
"...D-don't shove that thing in someone's face! And you just came that much, so why..."
"I figure Hayun-noona would like it even like this."
"......Ah. ...Mm. ...If it's Unnie..."
"Anyway. What do you want this time?"
"..."
Flustered. Embarrassed. And expectant. Lust, last of all. I gave that transparent mix of feelings a warm smile and went on.
"If you don't have an idea, I'll just tell you what to d—"
"...Uh, yesterday...!"
"...Yesterday?"
"Yesterday, with Unnie... what did you do...?"
"..."
Ah. That. I knew exactly what she was thinking the moment I heard it, but I wiped a hand across my mouth and kept acting as if I hadn't caught on. In front of her I was always the innocent, stupid Seo Woojin. I had to show her only that, or she wouldn't get aggressive about her little schemes. Think about it. Who actually believes the words sex practice? Either someone born a little slow, or a pervert who wants to fuck his girlfriend and her sex-obsessed little sister both. Those were the only two kinds.
"We had sex. You know that."
"...In more detail..."
"Detail?"
"Like...! Just... how you had sex. Or where..."
"...Ah."
"..."
Good. Where would it feel best to fuck Lee Jiyoon? I was turning over the studio—a little over three hundred square feet—looking for a decent spot, when it happened.
Bzzzz. Bzzzz.
A vibration, out of nowhere. A little away from us. The table. An odd place for a buzz to come from, unless a phone was sitting on it.
"......"
"......"
The thought chained fast. I always tossed my phone beside the bed, so the one on the table was Lee Jiyoon's. But she didn't really have anyone worth calling, did she? At most someone she gamed with who was actually close, or...
....
...Family. Lee Hayun.
I swept my slightly mussed bangs back and walked over to the table.
"......"
Yeah. The moment Lee Hayun lit up the screen, a sigh leaked out of me. Partly because she was cutting into my good time with Lee Jiyoon. And partly because it really did seem like nobody called this girl except her sister.
"It's Noona."
"...Lee Hayun?"
"Yeah."
"She always says calls are a pain and only uses Kakaotalk, so why all of a sudden...?"
Well. Thanks to that, I got to do something weird, so I couldn't say I hated it.
"Here. Phone."
"..."
Lee Jiyoon had already pulled the blanket over herself. She reached out one cute arm, and when I handed her the phone she cleared her throat and put it to her ear.
"...What."
"Hello? Jiyoon. When are you coming home?"
"In a bit. Why."
"Well, it's late and you're still not home, so I called. You didn't even open my Kakaotalk."
"...I was gaming. Didn't see it."
"You're still at the PC bang?"
"...Yeah."
Her voice sat oddly lower than when she talked to me, and it turned me on hard. Sitting right beside me, watching my face, stumbling through a lie to her own sister—that drove me out of my mind. So—
"It's already past ten?"
"What does that even matter...?!"
"Huh?"
"N-nothing. I'm... in a game with Woojin right now, and... an enemy. Showed up..."
"Aaah."
Less like sisters than like a mother and her daughter. Mid-conversation I yanked the blanket off Lee Jiyoon and, from that pale nape downward, one place after another, softly, started pressing my mouth to her. The way I'd carefully fondled her earlier, to ease the tension.
"And you didn't say anything weird to Woojin, right? That thing... about helping from the side."
"I—I didn't..."
Lee Jiyoon's brows twitched. She looked at me and shook her head hard, no, no, no. Seeing that, I rubbed her stiffened nipple and licked along her nape.
"Just try bringing that up with Woojin. If I even suspect it, I'm pouring water on your computer. I mean it."
"...... ..."
"Jiyoon?"
"...Mmph. Nn. Y-yeah."
Don't. Unnie will hear. She covered the receiver with her hand and whispered her anger into my ear. Hearing that, I traded saliva with Lee Jiyoon while the two of us listened to her sister nag. Every time I drew my lips away, her face asked, What if Unnie hears?! And still, when I mixed our breath again and kept it there, her eyes seemed to test me instead: You're dating Unnie, you know...? I kept kissing until Lee Jiyoon, ears flushed red, collapsed back onto the bed.
"So what time are you coming in?"
"...I-I'll probably be a little late..."
"So what time?"
"...Twelve? ......One?"
"One? In the morning? When you go to the PC bang you usually only stay an hour or two."
"That's for high-spec games.... When I go with a friend it's obviously longer..., ...ah, wait..."
I wiped my sticky lips on the back of my hand and gathered the feet that had been shoving at me, sweeping them off to the side. Right about when Lee Jiyoon mouthed don't, I caught one of her legs and forced it open, shoved it up toward her chest to make room, and ground my cock—harder than I had ever seen it—slick with her fluids, all over her soaked entrance. As if I were about to fuck her any second. Until, instead of muttering, she clamped her mouth shut just in case, I kept poking at the shallow stretch of her walls. The slick already pooled there glugged out and wet her own thighs, so I went a little faster.
"Enemy again?"
"Nnh, enemy.... An enemy came..."
"Eek.... What? Did you just do aegyo at me?"
"No, tha—... I, I bit my tongue. By accident..."
Maybe she wanted to hide her face, too. I looked down at Lee Jiyoon trying to cover both mouth and eyes with a single arm, and pushed my cock in right up to the dangerous edge. If I bottomed out she wouldn't be able to hold the moan, so only enough to feel good. If Lee Hayun caught this, the whole plan collapsed, so I absolutely would not cross the line. Lee Jiyoon had no choice but to take it shallower than before, teased and left wanting. I didn't care. Whatever pleasure she was missing, her sister's voice on the other end of the phone would fill it in.
"Anyway, don't work Woojin too hard. Got it?"
"...... ...Chup. ...Mph......"
"You're the one who only games, and Woojin's just playing along with you, so don't keep him forever. Are you even listening?"
"Fwehh.... Heh..."
"Hey, you're gaming and not even listening to your unn—!"
"Ah. Ah. Hello? Noona?"
"Ah, Woojin!"
Gently. Slowly. Teasingly. I stroked the head of Lee Jiyoon, who was trying not to let the sounds of the kiss get caught, and easily took the phone and put it to my own ear. And then, into the cunt I had been winding up every way I could think of, deep, I slammed my oversized cock. Thud. Thud. Thud.
"I'm fine. Even at home, when we game, Jiyoon and I usually go this late."
"That's just Jiyoon dragging you around by force."
"That's true, but... I've gotten used to it. Now."
"Haa. You've got it rough too.... Jiyoon's never really made friends, so she seems to follow you a lot. And you fixed her headaches, on top of it."
"...Yes."
Luckily Lee Jiyoon had her mouth clamped tight, so no moan leaked into the phone. My breathing hitched and I stumbled over a word, but from Lee Hayun's reaction she didn't seem to find it suspicious. So I drove into Lee Jiyoon without holding back.
"It's a long game, so not until one—I think we'll head home around twelve."
"I heard that before. Shooters take longer than you'd think. That's why they say to tell people before dinner, right? Did I mention it last time?"
"You don't even cook. You just game, and you still talk like that?"
"I'm telling you, she does. Next time I'm letting her starve. For real."
I flipped it onto speaker for a moment so she could hear her sister's voice. So nothing strange would leak in, I kept my cock buried to the hilt and only ground the tip in slow circles. When Lee Jiyoon, mouth sealed, finally came with her thighs trembling, I killed the speaker and talked to Lee Hayun as if nothing had happened. Then I pounded in as hard as I wanted. Even while I could clearly see Lee Jiyoon's chest heaving, up and down. And again, speaker on, I worked at her cervix without letting up.
"Oh, and Woojin."
"...Yes."
"Just in case—did Jiyoon say anything weird?"
"Weird.... Ah. That."
"Mmhm. That she wants to watch from the side when we do... that. Something like that."
"Well, like I said this afternoon, the intent is fi—ne, so I don't really mind.... Anyway, she didn't say anything like that."
"What about the intent is fine...! She's a virgin who's never done it once. What does she know, and what is she going to teach? At best it's stuff she picked up watching porn...."
"......"
All of it, played over the speaker for Lee Jiyoon to hear. And each time, I pressed below her navel with my fingertips. Every time I did, her walls clamped down on my cock. Because it felt good. When it got too tight and I pulled out, she squirted her slick in an obscene little spurt and swallowed the moan, and the sense of conquest nearly drove me insane.
"...Haa. When Jiyoon gets home, I'm going to scold her."
"......"
"I'll hang up first. I've got groceries to buy in the morning.... Bye-bye."
"...Head on in, Noona."
"Mmhm...."
Beep.
The moment the disconnect tone sounded, I glanced down at Lee Jiyoon's phone. No fingerprint lock. No pattern. Security awareness at absolute zero. Thanks to that, I didn't have to so much as shift; I just opened the camera on her phone as it was. And as hard as I had been holding back, violently, I started pounding her walls.
"...You can moan now. Noona hung up."
"You—damn—the phone—that's—recording..."
"It's your phone anyway. So what?"
"..."
"If it pisses you off, delete it later."
"..."
"If you need it, use it later."
"..."
I caught the bed's light, creaking complaint. I caught Lee Jiyoon's face—she had tried to glare as fiercely as she could, but with my cock driving into her and her panting, she only looked cute. I crushed her cervix however I wanted and recorded the moans that, until a moment ago, her palm had kept from escaping. After the deep climax ended, the breathless voice calling Seo Woojin, Seo Woojin, and the stumbling one: Just now, why did you kiss me? The voice she barely managed to push out in the middle of coming: You're dating Unnie... I put every one of those voices into Lee Jiyoon's phone. And one of my own, into her phone as well.
That was what I said.
