[Practice Sex (2)]
“Haa….”
“Heh…, heee….”
The sound of my glans buried deep into the most sensitive part of her pussy, the sound of my forehead pressed against a woman who, though silent, was clearly climaxing, and the sound of splat, splat-splat, as a massive load of semen flooded the taut condom. Could there be any sound more vulgar than this?
“...Stick out your tongue. Right here.”
“...Ugh….”
A kiss that had become all too familiar. As I did, I grabbed Lee Jiyoon’s wrists—which were obediently following my lead—with one hand and pinned them firmly against the pillow. They were so pale, having spent all her time cooped up in the corner of the room playing shooting games. Unlike a man’s, they were quite slender, so I worried a little that they might snap if I applied too much pressure. It was admirable how she just let herself be subdued, even though she could have struggled if it were too much.
…Maybe that was why. The more I touched those wrists, the more wicked thoughts filled my head. When she was barely visible on TV, she would wrinkle her face so much whenever she looked at the camera, but here, lying on the bed and looking into my eyes, she looked like she could barely keep them open because of the pleasure. I wanted to capture this expression of Lee Jiyoon’s in my eyes more and more. I wanted to ruin her as thoroughly as possible.
“...Are you okay? I feel like I came a lot more than usual….”
“...I, it felt…, …good, I guess.”
“You told me not to ask a woman that.”
“....”
“...Why? Are you curious? Do you want to hear it?”
“...You asshole. Just get lost….”
“It felt good. Honestly speaking…, way better than with your sister Hayoon.”
“....”
“...I’m going to change the condom first.”
“...Hey, take it slo….”
After saying exactly what Lee Jiyoon wanted to hear, I pulled my cock out, scraping against her hot vaginal walls. Seeing Lee Jiyoon go silent and start clenching down on me just from that, it was clear she’d already climaxed lightly once more…, but I didn’t want to dwell on that when there was so much left to do. Besides, there were plenty of condoms left. There was no need to be happy over something so small, right? How should I put it…. Ah, right. I had to drive her until her mind went blank and she made a ‘mistake.’ In this gloomy relationship that Lee Hayoon knew nothing about, I had to be the one firmly in control. …And after that, I could train Lee Jiyoon exactly to my tastes. Well, for now, that was all just a dream. But hey, what’s wrong with having a dream like this?
“Where should I put this? Should I give it to you?”
“Why, why would you give that to me…! You perverted bastard…!”
“Just in case. You can use it when you practice.”
“...Practice?”
“Yeah. Practicing things your sister Hayoon would like.”
“…….”
“If you don’t need it, just throw it away.”
“...Give, give it here. For now….”
I peeled off the condom, which hung heavy like a small water balloon because it was filled with semen, and handed it to her. She bit her lower lip, perhaps slightly flustered by the weight she felt the moment she took it—it was cute enough to make me want to take a picture—but I didn’t show it. I walked over to the head of the bed where I’d tossed the condom box earlier and picked one up. I’d wanted to make her clean my cock if things went south, but I skipped that. Judging by her reaction, she seemed to love kissing. I didn’t like the strange taste I got whenever I tangled my tongue with Lee Jiyoon’s, so I’d save that for the very end. If I wanted to make her do something like a deep-throat later, it would be better for her to build up the experience steadily.
“Haa…, what should we do this time? …Should we do it from behind to practice pulling your hair?”
Sniff, sniff. While I was putting on a new condom, Lee Jiyoon lay on the bed, carefully smelling the condom. When I asked her while thrusting my erect cock toward her face, her dreamily closing eyes widened slightly. …Lee Hayoon and Lee Jiyoon. Two people who didn’t look alike at all on the surface, but shared one identical thing. Those dark green eyes. Because of that, the reality that I was taking turns fucking ‘sisters’ felt so real that my cock grew even harder.
“...Don’t shove this thing in people’s faces! And why are you doing this when you just came this much….”
“I think your sister Hayoon would like it even if I did.”
“……Ah, …um, …if it’s… my sister….”
“Anyway. What should we do this time?”
“....”
Confusion. Shame. And, anticipation. Finally, sexual desire. I gave her a warm smile at that reaction, which was a mix of obvious emotions, and continued.
“If you don’t have any ideas, just do as I say….”
“...Ye, yesterday…!”
“...Yesterday?”
“What did you do… with my sister yesterday…?”
“....”
Ah. So that’s it. I realized what she was thinking the moment she said it, but I wiped around my mouth with my hand and continued to act as if I hadn’t noticed. In front of her, I always had to be the ‘naive and stupid’ Seo Woojin. I had to show her only that side of me so that Lee Jiyoon would also actively try to do her own dirty deeds. Think about it logically: who would actually believe the words ‘sex practice’? Either someone born a bit slow, or a perverted bastard who wants to fuck his girlfriend’s younger sister. There are only two types of people like that.
“We had sex. You know that.”
“...Tell me in more detail….”
“Detail?”
“Like…! Like…, how you had sex…. Where you had sex….”
“...Ah.”
“....”
Good. Where would it feel good to have sex with Lee Jiyoon? I was looking around the studio apartment, which was a little over 300 square feet, trying to pick a suitable spot.
-Vrrr. Vrrr.
Suddenly, I heard a vibration. The direction was a bit away from us. The table. It was a bit of an odd place for a vibration to come from, but it was a different story if a phone was sitting there.
“…….”
“…….”
My thoughts connected quickly. My phone was always tossed next to the bed. So, the one on the table was Lee Jiyoon’s phone. But she didn’t really have any friends to contact her, did she? Then at best, it would be someone she was really close with among the people she played games with, or….
…. …Family. Lee Hayoon.
I brushed back my slightly messy bangs and walked toward the table.
“…….”
As expected. I let out a sigh the moment I saw the name 「Lee Hayoon」 floating on the screen. Partly because my fun time with Lee Jiyoon had been briefly interrupted. And partly because I thought, does she really have no one else to call her besides her sister?
“It’s your sister calling.”
“...Lee Hayoon?”
“Yeah.”
“She always just sends KakaoTalks saying she’s busy, so why suddenly…?”
Well, thanks to that, I could do ‘strange things,’ so I didn’t exactly hate it.
“Here. Phone.”
“....”
Lee Jiyoon, who had already covered her body with the blanket, reached out her arm cutely. When I handed her the phone, she cleared her throat and brought it to her ear.
“...Why.”
-Hello? Jiyoon-ah. When are you coming home?
“In a bit. Why.”
-No~ It’s late and you weren’t home yet, so I called. You even left my KakaoTalks on read.
“...I was playing a game, so I didn’t see it.”
-Are you still at the PC bang?
“...Yeah.”
Her voice, which was strangely lower in tone than when she talked to me, was incredibly arousing. Seeing her hesitate and lie to her sister while being conscious of me sitting right next to her was maddeningly arousing.
…So,
-It’s already past 10 o’clock?
“What does that have to do with…?!”
-Huh?
“A, ah, no. I’m currently playing a game with Woojin…, an e, enemy… appeared….”
-Ah.
I forcibly pulled the blanket off Lee Jiyoon, who was having a conversation that felt more like a mother and daughter than sisters, and started kissing her, softly and in order, starting from her pale neck. Just like I had carefully caressed her earlier to relax her tension.
-And you didn’t say anything strange to Woojin, did you? That thing about… helping out from the side.
“I, I didn’t….”
Lee Jiyoon, who had slightly furrowed her brows, looked at me and shook her head diligently. Seeing that, I pressed down on her hardened nipples and licked her neck.
-Just try bringing that up to Woojin for no reason. If I find anything suspicious, I’m going to pour water on your computer. Seriously.
“……, ….”
-Jiyoon-ah?
“……Pfft, ugh, uh-huh.”
Don’t do it. My sister will hear. Lee Jiyoon, covering the receiver with her hand, whispered angrily in my ear. Hearing that, I shared saliva with Lee Jiyoon while listening to her sister’s nagging. Even though every time I pulled my lips away, Lee Jiyoon asked with her expression, ‘What if my sister hears!’ Even though, even when I mixed my breath with hers for a long time again, she asked as if testing me, ‘You’re dating my sister, aren’t you…?’ I continued the kiss until Lee Jiyoon, her ears flushed red, collapsed onto the bed.
-So, what time are you coming in?
“...I, I think I’ll be a little late….”
-So what time?
“...12 o’clock? ……1 o’clock?”
-1 o’clock? In the morning? You usually only stayed for an hour or two when you went to the PC bang?
“That’s for high-spec games…. When I go with a friend, obviously it takes longer…, …ah, wait….”
I wiped my sticky lips with the back of my hand and pushed Lee Jiyoon’s feet, which had been pushing my body away until just now, together and moved them to the side. Then, just as Lee Jiyoon was muttering ‘don’t do it’ with her lips, I grabbed one of her legs and forced it open, made space by pushing it up to her chest, and rubbed my cock, which had become fuller than ever, against her pre-cum-covered vaginal opening. …With the intention of fucking her right then and there. I poked at the shallow parts of her vaginal wall until Lee Jiyoon, instead of muttering, clamped her mouth shut just in case. Seeing the pre-cum that had already pooled leak out and soak her own thighs, I increased the speed just a little more.
-Did an enemy come again?
“Umm, enemy…. The enemy came….”
-Ugh…. What? Were you just acting cute?
“No, that…, I, I accidentally bit my tongue….”
Did she want to hide her expression too? Watching Lee Jiyoon, who tried to cover her mouth and eyes with just one arm, I shoved my cock into the most dangerous spot. If I shoved it in all the way, she wouldn’t be able to hold back her moans, so I only did it just enough to feel good. If Lee Hayoon found out about this situation, my plan would fall apart, so I had to make sure I never crossed the line. Lee Jiyoon would inevitably feel frustrated because it was shallower than before, but it didn’t matter. The sister’s voice over the phone would fill in the missing pleasure.
-Anyway, don’t overwork Woojin too much. Okay?
“……. …Chup. …Pff…….”
-You’re the one who only plays games, and Woojin is just playing with you, so don’t hold onto him for too long. Are you listening?
“Pff-hee…. Heh….”
-Hey, are you not listening to your sister because you’re playing games…!
“Ah. Ah. Hello? Sister?”
-Ah, Woojin-ah!
Gently. Slowly. Teasingly. I stroked the head of Lee Jiyoon, who was trying hard not to let her moans be heard, easily snatched the phone, and brought it to my ear. And then, I thrust my thick cock deep into the pussy that had been teased in every way possible, thwack, thwack, thwack.
“I’m fine. I’m used to playing games at home with Jiyoon until this time anyway.”
-That’s because Jiyoon drags you around forcibly.
“That may be, but…, I’ve gotten used to it. Now.”
-Haa. You’re having a hard time too…. Jiyoon hasn’t really made friends before, so she seems to follow you a lot. You even fixed her headaches.
“...Yeah.”
Fortunately, because Lee Jiyoon was clamping her mouth shut, no moans leaked into the phone. Although I stuttered a bit because my breathing was tangled, judging by Lee Hayoon’s reaction, she didn’t seem to find it particularly suspicious. So, I pushed Lee Jiyoon without worry.
“It’s a long game, so I don’t think I’ll be home by 1, but maybe around 12…, …I think I’ll be home.”
-I heard a long time ago. That shooting games take longer than you think. So didn’t I tell you to say so in advance when you eat dinner? Did I tell you that last time?
“It’s not like I’m cooking myself, I’m just playing games, sigh…, do you have to say that?”
-I told you, didn’t I? Next time, I’ll starve you. Seriously.
I turned on the speakerphone slightly to let her hear her sister’s voice. While keeping my cock shoved in all the way, I stimulated her by rubbing only the tip in a circular motion so that no strange sounds would leak in. Eventually, when Lee Jiyoon, who had been clamping her mouth shut, climaxed while her thighs trembled violently, I turned off the speakerphone again, talked to Lee Hayoon as if nothing had happened, and shoved my cock in to my heart’s content. Thwack, thwack, thwack. …Even while clearly seeing Lee Jiyoon’s chest rising and falling heavily. Again, with the speakerphone on, I obsessively stimulated her cervix.
-Ah, and Woojin-ah.
“...Yes.”
-I’m asking just in case, but did Jiyoon say anything strange?
“Strange…. Ah, that.”
-Yeah, yeah. Like wanting to watch from the side when we do… that.
“Well, as I said during the day, the intent is good, so I didn’t think much of it…. Anyway, she didn’t say anything like that.”
-What do you mean the intent is good…! She’s a virgin who’s never had experience in the first place, what does she know and what could she teach…! At best, it would be knowledge learned from watching porn….”
“…….”
Everything. I let Lee Jiyoon hear it through the speakerphone. I pressed my fingertips firmly below her navel. …Every time I did, her vaginal walls would clench down on my cock. It felt so good. When I pulled my cock out because it felt like she was clenching too hard, the way she would let out a vulgar squirt of pre-cum and hold back her moans made me feel so conquered I thought I’d go crazy.
-…Haa. I’ll have to scold Jiyoon when she gets home.
“…….”
-I’ll hang up first. I have to go grocery shopping tomorrow morning…. Bye-bye.
“...Take care. Sister.”
-Yeah, yeah…. Beep.
The moment I heard the sound of the call ending, I glanced down at Lee Jiyoon’s phone. A phone with zero security consciousness, no common fingerprint lock, no pattern lock. Thanks to that, I didn’t need to move around inconveniently, I just took out the camera from Lee Jiyoon’s phone as it was. And then, as much as I had held back, I started to thrust into Lee Jiyoon’s vaginal walls violently.
“...You can moan now. Your sister hung up.”
“You, you, phone, that, recording….”
“It’s your phone anyway. Why?”
“....”
“If it’s shitty, delete it later.”
“....”
“Use it later if you need to.”
“....”
I captured the sound of the bed screaming as it creaked. I captured Lee Jiyoon’s expression, which looked as fierce as possible, but only looked cute because she was panting while being fucked. I pressed down on her cervix as hard as my desire allowed, and recorded the moans that hadn’t been able to leak out because they were blocked by her palm until just now. After the deep climax ended, the breathless voice of Seo Woojin, Seo Woojin, and the voice that came out stuttering, Why, did, you, kiss, me, just, now? The voice that barely managed to spit out while climaxing, saying, You’re, dating, my, sister…. I put all those voices into Lee Jiyoon’s phone, and I put one of my own voices into her phone, too. Think whatever you want.
