My Sister and I (4)
I let out a shaky breath. Her pussy twitched around my cock, clenching in time with the movement of her hips. Blood was clearly visible between our joined bodies.
“...You okay?”
“Mmm...”
Just from the sound of her voice, it was obvious she wasn’t. From what I knew, it was the kind of pain that came from skin that had been stuck together finally pulling apart. I’d seen other people move just fine in videos, but seeing it up close like this made it feel impossible to continue.
“Hurry... move already...”
“But doesn’t it hurt...?”
“It hurts more... when you stay still like this... pressing on it...”
“Ah... right.”
If my sister told me to move, I had no choice but to move. I started rocking my hips back and forth as slowly and carefully as I could.
Is this how you’re supposed to do it...?
In the videos, everyone was thrusting like crazy. It was harder than I expected. My movements felt clumsy and awkward. Suddenly, all those stories about people failing their first times flooded my mind, and fear started creeping in. After finally getting it in, was I really going to finish like some pathetic amateur? No way. Absolutely not.
“Mmm, ahh...”
I stopped again, then started moving with my waist instead of just my legs. I gripped her hips like handles and made sure our joined parts slammed together properly. I poured all my determination into not letting this end in failure.
“...!”
“Hngh!”
Now that we were properly aligned, my cock, which had only been halfway in before, slid all the way inside. Her inner walls, which had been pushing back, began to writhe and pulse around me.
“Haa, ah. Ngh...”
“Haa...”
Once I got one good thrust in, the rhythm came naturally. The heat that had cooled slightly began to rise again.
“Whoa...”
My once-dry cock was now slick, and wet, squelching sounds started to fill the room. My confidence grew with every movement. The bright red color that had made me nervous at first gradually faded, coated in her cloudy fluids. Every time I pulled out and pushed back in, her inner folds scraped firmly along my shaft. That electric jolt raced up my spine and straight to the back of my head.
“Ah, wait, just a sec—?!”
I was determined to break through her resisting walls and reach the deepest part. Slowly, deliberately, I drove all the way in. The pressure of her ass pressing against my groin told me her insides were stretching wider and wider.
“Wow... sis...”
“What...?”
“This feels so good...”
“What are you even saying— ngh. Ngh, ah, hngh!”
My pace gradually quickened. The sensation of my glans rubbing against her walls grew stronger, and strength began to drain from my lower body.
Not yet—
Splurt.
“Hngh.”
An unstoppable groan escaped me as cum just poured out. I tried my hardest to hold it back, but my body refused to listen. I’d clenched harder than when trying to hold in piss, so why was this happening?
“Haa...”
After that first spurt, the rest came in thick, heavy bursts like usual. Maybe because I’d held it in so much yesterday, it felt like more than normal. Pulling my cock out while still sensitive was an overwhelming sensation.
Whoa.
Unlike people who said it wasn’t that great, I thought it felt amazing. Whether it was just sex in general or because it was with my sister, I couldn’t tell. Either way, it was good. The only downside was how embarrassingly fast I’d finished. I’d thought I’d be different, but I guess everyone’s the same.
“...Is it over?”
“Yeah...”
My sister looked back at me with a pained expression, her ass still pointed in my direction. She only turned her head slightly to glance at me. Her face, usually so pale, was now flushed bright red.
“Did I... finish too fast?”
Like a thief with a guilty conscience, the words slipped out before I could stop them. Honestly, yeah, I had finished quickly.
“That thing... is it yours, Jiyun...?”
“What is?”
“The thing... caught on there...”
“Ah... yeah.”
What she was pointing at was the condom still on my cock. It wasn’t ballooned out like in cartoons, but I’d definitely cum enough that it needed to be tied off.
“Whoa.”
When I pulled the condom off, she actually grabbed it with her hand. She turned it this way and that, staring at it like the dirty thing was somehow fascinating.
“Stop that. Don’t look at it...”
“Why not?”
“I don’t know. It’s embarrassing.”
My cum wasn’t a toy. She shouldn’t be looking at it with such curiosity.
“Oh.”
“What?”
“It went down.”
“...Yeah, it did.”
What the hell? In comics, it never went soft no matter how many times they came. So reality really was different.
“...Is that it?”
“...Why?”
“No... just...”
Her eyes darted around as she hesitated. It was clear she wanted to do more. Still, it was fascinating. Even though my sister was completely naked in front of me, not a drop of blood was flowing downward. My heart was pounding like crazy, though.
“...?!”
“You’re not the only one who did some prep work, you know.”
“I didn’t do any prep...”
“Liar.”
It wasn’t prep. It was review. ...Since I hadn’t actually done it before, did that still count as prep? But if that was the case, then the fact that my sister had also prepared meant—
“Hoo...”
She wiped my cock clean with a tissue. It wasn’t even a blowjob, so why was it so arousing? The way she gently pressed on my balls felt like a fresh new kind of stimulation.
“...Jiyun. No, Pa-ttak... No, Jiyun.”
“Pick one—”
“What’s the most times you’ve done it in one day?”
“Huh?”
My sister suddenly asked something weird. The most times? Like some kind of masturbation record?
“...I don’t know. I don’t really remember, but I think I’ve gone up to five times.”
That day I’d been insanely horny. I kept stroking even after I came, over and over, until the thick white stuff turned thin and clear. I remembered training myself alone, falling into corruption. I even bragged to my friends that five times in a row was my record. What the hell was I thinking?
“What about you, sis?”
“...I don’t remember.”
“What? I told you mine. You have to tell me too.”
“...I really don’t know.”
“Why don’t you know?”
“......Ten.”
“What?”
There were only the two of us here, so why was she whispering like that? I leaned in closer to hear better, and she whispered directly into my ear.
“After ten times... I lose count.”
“......Is that counting orgasms?”
“......Yes.”
“......”
Along with a surge of arousal, I suddenly wanted to make her cum that many times too. To reach ten, I’d have to make her cum with every thrust. Could a guy who’d just lost his virginity really pull that off?
“Oh.”
“......”
Maybe because of the dirty talk, blood started rushing back down. It was still soft, but I could see it growing bigger.
“Ngh...”
“How’s that?”
Now she was confidently gripping and stroking my cock. Her technique was a bit clumsy, but because I was so sensitive, it still felt incredibly good.
“A little harder...”
My cock grew firmer, demanding a stronger grip. Of course. I jerked off at full strength every day. There was no way her grip could satisfy me like this.
“Harder...?”
“Yeah... harder...”
She switched hands as she worked me up. It wasn’t as hard as before, but my cock had stiffened considerably. It looked like I’d need to put it back in to get fully hard again.
“Ugh... my arm hurts.”
“That’s because your muscles aren’t developed enough.”
“Is that it?”
No matter how much she masturbated, the muscles used were different, so it made sense that her arm would get tired after just a little while.
“......Want me to do it for you?”
“What?!”
“No, I mean... you did it for me, so... I thought I should return the favor...”
“Can you even do it...?”
“I don’t know.”
I decided to base my movements on the brief moment I’d had my fingers inside her earlier, plus all the visual and audio material I’d studied. If it didn’t work, it didn’t work. This was my first time anyway.
“Spread your legs.”
“What?!”
“I mean... your legs. Spread them. So I can put them in.”
I couldn’t think of any other way to say it. How else was I supposed to phrase it?
“Put your pussy toward me.”
Yeah, I couldn’t say that.
“Just wait a second...”
She turned her ass toward me again and got on all fours. Wait, she’d already shown me her breasts and everything, so why was she turning away now that I was about to put it in? I wanted to see her face.
“...Okay, I’m ready.”
“Yeah.”
“Hngh!”
I carefully stroked down her ass and searched for her entrance. It looked a little more open than before.
It was definitely right here.
I secretly sucked on the finger that had been inside her earlier, coating it with saliva, then slowly pushed my middle finger in. This time, since she was in position instead of lying down, it was much easier to move.
“Ugh...”
“Can I add another...?”
“Mmm... go ahead...”
With her permission, I added my ring finger. I pressed against her inner walls and moved them slowly back and forth. I could feel every single ridge and fold.
“Haa, ah. Mmm, hngh...”
Her lewd sounds made blood rush to my groin without me even trying. The faster I moved, the louder the wet squelching grew.
“Wait, uwaaaaah...!”
“Whoa...”
I focused on the spot that made her twitch the most every time I passed it. The sound changed from squelching to splashing, and fluid began to drip out. So this was what it looked like when she came. As expected from the Ju-ttak, she really produced a lot of water.
“Haaah... ngh...”
I wondered what kind of face my sister was making right now. Was her mouth puckered up like those twitching holes? Or was her expression completely unchanged, just pretending to feel good?
“Look at me.”
“No, don’t...!”
Since we’d come this far, I wanted to see what she looked like when she felt good. After all, this was technically a meeting. A meeting was about coming together to coordinate. Whether the deal went through depended on all kinds of visible and invisible factors. Right now, I absolutely had to succeed in this coordination to earn the Ju-ttak’s trust.
...Okay, fine. I just really wanted to see her face.
“I don’t want to... ngh...”
I pulled my fingers out of her and pushed her forward so she was lying down. She covered her face with her hands, but her legs were spread, leaving her dripping pussy completely exposed.
“What don’t you want?”
“Just wait, ugh...!”
I kept pushing her resisting arms away until she finally gave up and just covered her face. I forced her legs apart again and found the hole that was leaking so much fluid.
“I’m really, really embarrassed...”
“......But. So what?”
“So... stop—”
This time I pushed two fingers in at once. She flinched hard and tried to push my arm away with one hand, but it was useless.
“Ohh, uuuugh?!”
I moved my wrist and fingers the way I’d seen in porn, and her back arched upward. So this was what they meant by bending like a bow.
“S-stop...”
“I’ll stop if you show me your face.”
“I don’t want to...”
“Why...?”
“My face looks weird right now...”
Was her body not weird then? It wasn’t weird. It was beautiful. Though honestly, her body was so lewd it was almost vulgar. Her breasts and pussy were this obscene, so how vulgar must her face be? The more she tried to hide it, the more curious I became. I wanted to see that “weird” face.
“S-stooooop...!”
She started squirting again. There was so much I could have caught it in a cup. I kind of wanted to drink it all.
“Haa... huuuuuh...!”
When I pulled my fingers out, there was an audible pop. I hoped she didn’t see the smile that crept across my face.
“Show me your face already.”
“......”
She pressed her lips together tightly, then spread her fingers just enough to show one eye. I couldn’t take it anymore and just brushed her hand away.
“......”
“Ugh...”
“What? You’re just cute.”
“No... hey...”
Where was the part that was supposed to be weird? I couldn’t see anything strange. If I had to point out something, maybe her voice was a little hoarse?
“...Jiyun.”
Once she got used to me seeing her face, she looked at my cock and spoke.
“It’s hard again...?”
“Yeah.”
When I got into position, this time she spread her legs while facing me. It was way more arousing than just staring at her ass.
...One left.
I put on the last remaining condom. I was already getting used to it.
“Haa... ngh.”
Without a word, I pushed my cock back inside her. It went in much more easily than the first time.
“Doesn’t it hurt anymore?”
“No. It doesn’t hurt because it’s yours, Jiyun.”
“......”
Now I knew for sure. It wasn’t that sex felt good. It felt good because the person I was having it with was my sister.
