One Actor, Two Civilians
Brighter than me. Cuter than me. Smarter than me. An older sister who lacks absolutely nothing. In front of such a sister, I... I personally peel off the condom from the tip of her boyfriend's penis, a condom now bulging at the end with semen.
"...Do you always cum this much when you're with my sister?"
"...I don't know. Who the hell checks that kind of thing one by one?"
"Still, you must have noticed something."
"..."
"Is it similar? To this?"
"...Yeah."
Heh. So this is the average... As expected, he cums much less than when he ejaculates inside me. Well, I suppose it's hard to be satisfied even with a condom on, especially when we've already done it raw.
I stare at the dazed-looking Seo Woojin, though that's all I'm thinking about on the inside.
"...Here. Your sister's."
"..."
I do it with all my heart, just as Seo Woojin ordered. I glance at my sister right next to me, wearing a resentful expression. After all, the 'tampered' condoms my sister had been receiving these past few days were filled with far less semen than this. Regardless of the backstory, I'm the loser right now, aren't I? ...So enjoy it while you can. Because in a little while, you'll have no choice but to be incredibly jealous of me, sister.
"And sister, move over a bit. Don't just keep lying on the sofa."
"...Yeo, Yeo-woon... because of..."
"Then should I go into your room and get them? The condoms?"
"..."
Did she hate the idea of me entering the space she shares with her boyfriend? My sister, who was lying on the sofa panting, groans and tosses one of the condom boxes buried in the corner of the sofa at me. I pick it up as it flies through the air and hits my chest—it's not a new one, but the box we just opened earlier. Since we just used one, there are two left. I take one out, tear it open in front of my sister, and then... I turn around.
"...Hey, wait... It's heavy..."
"Mmph. ...Mmph."
I sit on top of my sister—just slightly, really—and look at Seo Woojin with the large, scentless condom, smelling only faintly of rubber, held cutely between my lips. You wanted to see this, didn't you? Right? You wanted to see my sister and me fighting over your dick, didn't you? You... you pervert.
"..."
Seeing it stand this stiff instead of going soft even after cumming earlier, I guess I was right. ...You're an even bigger pervert than me. Pfft...
"Mmph, heumph..."
If I exaggerate a little, it's a dick the size of my forearm. If I put it vertically over my face, I wonder if it would barely cover my lips. If I put it horizontally, it would definitely cover both my eyes—a dick covered in veins. I press my lips to the tip as if kissing it, and without delay, I take it deep into my mouth. The tip of my tongue. The roof of my mouth. ...Maybe, my uvula. I push it all the way to the back, right to the entrance of my throat where I start to gag.
"Ph..."
Even so, I stare blankly at the remaining half of Seo Woojin's dick, and out of curiosity, I try to force it down my throat, wondering if I could fit it if I tilted my head back... but then, I end up spitting out the condom-covered dick, trailing a thick, sticky string of saliva. ...I thought I'd gotten a little used to it, but I guess I still can't do this. Is there something else? Something that pervert would like... an act that makes him stand his dick up, right in front of two sisters who hate each other? He'd probably like us to have a threesome with him all night, but looking at my sister's reaction, that'll be hard for now.
Ah. How about this?
"...Hehe. It feels even bigger than when you were with my sister earlier..."
"Who knows."
"Just say yes. You can't see it from my sister's position."
"Hey, Lee Jiyoon...!"
"..."
She just barks my name, but she doesn't actually hit me or anything. Sitting on top of my sister, I smile brightly, pull the half-worn condom back slightly, and pretend to give him a blowjob. I chew on the useless rubber tip with my front teeth. I pull at it lightly with my teeth, as if I want to tear it off without my sister knowing. *Swoosh, swoosh.* Slowly. Down to the root of your dick, which is twitching with pleasure. How about pulling the condom down slowly like this?
"...Ptooey."
It was fine until a moment ago, but now the tip of the condom is a crumpled, saliva-soaked mess. I break the silver thread connecting it to my lips with my tongue and smile brightly. I didn't tear the tip of the condom with just this, but... I definitely noticed that Seo Woojin's dick had become hotter and harder, even if I wasn't sure if it had grown any bigger. He must like it. ...You pervert.
"..."
"..."
"I, I put it all on..."
Was I a little excited too? The embarrassment that should have come sooner spreads like cotton candy only after it's all over. ...I thought I wouldn't be embarrassed by anything anymore since we've already done it inside, but I guess it's because this is my first time begging for it while sitting on top of my sister.
"Then now..."
But I can't just hang my head in shame in a situation like this. I swallow my embarrassment, pretending to be fine, and look behind me. My sister, who had calmed down quite a bit while I was putting on the condom, comes into view. She has a very lewd face, as if the lingering effects are still there—a little different from the cute sister I've seen for 20 years. Do I make that expression right after having sex with Seo Woojin? With that thought passing through my mind, I tuck my hair behind my ears, put on a playful smile, and start to get into position. I kneel by her pelvis before my sister can slip away. If I lean forward with my hands on her shoulders... done.
"Hey, get off... What are you doing on top of me..."
"Doggy style."
When I answer, enunciating every syllable clearly, my sister's cheeks, which had returned to their original color, turn red again. It's not like she's reacting that way because she's never had sex in this position before. The cause is probably this. Because of my arms and legs, which have restrained my sister so she absolutely cannot escape unless she pushes me away and forces her way out.
"I, I know that too...! I told you to move me to the side and do it...!"
"Why?"
Why should I? If my sister watches from the side, Seo Woojin won't press his dick between my buttocks like this. He won't shyly spread my pussy, dripping with love juices, with his thumb. Like this.
"Instead of standing on the side and watching until your legs hurt, just under me..., ...ugh..."
He wouldn't tease me by pretending to make a mistake and bouncing off, even though he was about to shove it in, glans first.
"...Seo, Seo Woojin... Stop..."
"..."
"...Hit...!"
...He wouldn't have rubbed his glans against my vaginal opening like that. And then, all at once. *Push, push.* He wouldn't have just tried to shove his dick in as he pleased, without caring about me at all. Why would I let my sister go...? ...Just, can't you play the role of the bed? Quietly? Seo Woojin likes it. I like it too. It's more arousing that way.
"Cee..., yeah, heu-geuk..., ugh..."
"...Hey, Jiyoon..."
The glans that was pressing against the roof of my mouth and throat just a moment ago. Feeling it reshape my vaginal walls to its own form, I exhale hot breaths toward my sister, who is lying right beneath me with her ears turning red. ...Is it because I'm using my sister as a bed? Seo Woojin isn't treating me roughly like he usually does. Well, to be precise, it's like... after he mistook the things I told him were 'my sister's preferences' for 'my preferences'...
He isn't grabbing my pelvis tightly and thrusting until my ass makes *thwack, thwack* sounds. He isn't pressing me into the sofa and thrusting his dick in like he did with my sister earlier. Instead, he's slow, as if he's savoring every inch of my vaginal walls. It's so frustrating I could die... but.
"Hi... eek...? ...Ah...?"
If we're talking about the sheer amount of pleasure, mating like beasts until we can't breathe is much, much better—the comparison is meaningless. But if we're talking about the 'quality' of pleasure... would that be strange? Every time Seo Woojin grabs my pelvis lightly and rubs against my vaginal walls, the tingling pleasure that travels up my spine is... something. It was so dangerous that...
"...Wait... Wait a minute..."
Somehow, the same words my sister said just a moment ago. I whisper them with difficulty and lower my posture. ...Annoyingly. Because I can no longer hold myself up with my arms stretched out. Until my chest touches my sister's.
"...I can't breathe..."
"Ugh, ugh..."
Is it because of the atmosphere? Or because I'm actually having sex in front of my sister...? The speculation is short-lived; my sister murmurs that she can't breathe and carefully supports my shoulders. Lying limp on top of my sister, I bury my face next to her head and let out only shameful moans. As loudly as my sister's voice sounds right now, my voice must sound just as loud to her. I'm so embarrassed thinking about what my sister would think of me seeing me like this.
In the midst of this, the pleasure tingling from my vaginal walls doesn't decrease; it only keeps growing. Even though his dick hasn't entered all the way even once yet. The dick that rubs against my vaginal walls as if targeting only my weak points. ...Honestly, more than I thought. It feels too good...
"......Hick...♡"
In the end, I spray a shameful liquid all over the sofa. *Pfft, pfyut.* The sound of the liquid being forced out through the narrow hole hits my eardrums along with the sound of my sister swallowing right next to me. Once. Twice. Three... times. What I had been holding back keeps leaking out. ...To the point where counting is meaningless.
"Hey, Woojin..."
"...Yes."
"Is Jiyoon like this usually...?"
"..."
I'm not like this. Do you think I'm like this usually? It's just that right now... something is strange. Even if I try to explain that, all that leaks out of my mouth are vulgar moans. In the end, all that's left is Seo Woojin's answer of 'No.'
"Usually, that's... right."
"......Heu-geuk?!♡ ...Ugh...?"
Because Seo Woojin, talking nonsense, shoves his dick all the way into my womb for the first time. The shameful moans I didn't want to let others hear and the lewd sound of water soaking the sofa only increase.
"...You were quite sensitive."
"...Similar to you, sister. I don't know if it's because you're sisters."
"Hah..., haah..."
"I, I don't twitch like this, do I...!"
"Don't you remember you two minutes ago?"
"...Ung-hick..."
"That was...! That..., Jiyoon pressed my lower abdomen..."
"Lower abdomen?"
"Hek, he..."
The two of them are talking casually even though I'm about to go crazy because my vision is turning white. Is it because I was just clenching my dick between them without being able to join in? Or was I waiting for this to happen from the beginning? ...Now that he's finally in the mood, Seo Woojin starts thrusting his dick in deep.
"...I don't know exactly, but when you pressed my lower abdomen.... ...It felt strange."
"How did you do it?"
"...Hah, ...ugh."
"Like this...?"
"Ung-hick?!? Wait, sister... Lee Hayoon... ...Sister...!"
And that's because my sister pressed her finger firmly against my lower abdomen.
"...Yeah. Really... right? You can feel it moving... a little."
"Take, take your hand off... Please..."
"...Why? You did it too, didn't you?"
"I was wrong, I was wrong... Sister..."
Unlike me, who only pressed it for a moment and took my hand off, she pressed her finger firmly right under where my womb is, as if to make me die of pleasure. Seo Woojin, who has been holding onto my pelvis, hasn't given me a single break since earlier.
"...Wow. Look at that love juice..."
"......♡ .........♡♡"
On my sister's shoulder. With my face buried in the sofa, which is damp from the saliva I've been drooling, there's nothing I can do but twitch my whole body and spray love juice. Nothing else I can do.
"Jiyoon. Are you okay?"
"...Heek..., he..."
Does this really look okay to you? Even if you just look from the side, my sister must have noticed that I was about to break down, right? Is this what they call a psychological battle between women? I, who could do nothing but catch my breath, answer by lightly biting my sister's shoulder, which I could see in front of me.
"Hey. ...It hurts... Why are you biting me..."
"....... ...."
However. For some reason.
"......Ung-hick.... ...Hick...♡"
Seo Woojin, who has nothing to do with this, is... thrusting his dick in harder than before. Could it be that he's excited seeing sisters do this?
"Haa..., haa..."
...You pervert. You really want to see something like a lesbian play. I looked it up roughly because I thought you'd like it, but... ...Ah, damn... I wouldn't mind if it were a total stranger, but I absolutely don't want to do that with my sister. .... ...You asshole.
"Ah, don't lick it because it hurts... ...It tickles, so don't..."
"..."
"...Jiyoon? Hey..."
Because Seo Woojin likes it. The more Seo Woojin likes it, the more... he'll thrust his dick in hard.
"......Tsk..."
"Ah, ah, ...ah..., .........♡"
Seo Woojin, who is grabbing my pelvis with one hand and thrusting into my vaginal walls. After being subjected to a violent mating that is incomparable to the flat piston thrusting from the beginning. In the end, I lick my sister's shoulder, which is already soaked in saliva.
"...Ah, so amazing..."
I accept all of Seo Woojin's semen, which he ejaculates beyond my womb as if he's going to get me pregnant. Through the condom that, unfortunately—or perhaps fortunately—was torn properly at the tip. A lot.
