Burning Friday (2)

"Where did you go on your trip?"

"It’s not really a trip... I came to Ilsan."

"Why Ilsan?"

"Chaeyu said there was something she wanted to see here... I didn't feel right about sending her alone."

"Alright, I understand. Don't stay out too late. Call me again from your accommodation later."

"Yes."

To lie about being in Ilsan, I had actually come all the way to Ilsan. Then, I called Mom to tell her I’d be staying the night.

"What did she say?"

"She said to have fun."

"That’s a relief."

"Why? Did Mom not let you stay out overnight often?"

"Yeah. Even when I told her I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠was with a female friend, she said no."

"She must have been really worried. It would be a disaster if you ran into some weirdo."

"Are you okay with it, Oppa?"

"I’m family."

"...We’re a weird kind of family."

"I won't deny that."

Once I’d actually lied to Mom, a strange sense of guilt welled up inside me. Especially since the reason for the lie was to sleep with my younger sister.

"I'm tired."

"Let's head in quickly."

We found a decent-looking motel and went inside. It felt like something we’d done many times before.

"Don't we do this a lot?"

"Yeah, we do."

Chaeyu seemed to share the same sentiment, voicing the question. Whenever we hung out and night fell, we’d always find a suitable place to stay.

"Do you want to shower first?"

"Sure."

While Chaeyu went in to shower, I checked the supplies. Toothbrushes, feminine wash, other miscellaneous items, and most importantly, condoms. I wasn't surprised, as these were things I saw all the time. It was a good thing I’d brought one from home. The ones at the motel were too thick and didn't feel like anything.

"Whew..."

"What's up? You came out fully dressed."

"Yeah."

Usually, she’d come out in just a robe, but today she was wearing the clothes she’d arrived in. I secretly wanted to ask why, but I didn't want to make it obvious.

"You go in too, Oppa. The shampoo here is really good."

"Is it?"

Since Chaeyu wasn't wearing a robe, it was probably better if I didn't either. If I were the only one wearing one, it might look like I was signaling that I wanted to do something.

"How’s the shampoo? Good, right?"

"...Honestly, I can't tell the difference."

"This is why men are..."

Chaeyu held out her hair for me to smell. I grabbed it and took a whiff; it smelled nice.

"How is it?"

"It smells different than usual."

"Isn't it better?"

"Both are good, though?"

"...You’re really frustrating."

"Men just don't know about these things..."

Especially for someone like me who has no interest in fashion. I usually just use cheap deodorant, or most of the time, I don't even use that.

"Want to watch a movie for a change?"

"I'd love to."

To change the subject, I suggested a movie. I quickly turned on the TV, afraid she’d start talking about shampoo again.

"Have you seen any movies lately, Oppa?"

"No. I've been too busy. Put on whatever you want to watch."

"Okay. Can we watch this one?"

"What kind of movie is it?"

"Spy action."

"Oh. Sounds fun."

I like action movies, but personally, I prefer the kind that isn't just ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠blatant action—the ones where they secretly shoot guns or infiltrate places. Whether the sound of a suppressed gun is historically accurate or not is still a hot topic, but honestly, I think as long as it's fun, that's enough.

Punch cards are a staple in movies like this. Since headquarters usually needs to be completely cut off from the outside world, they often insist on using analog technology. Thinking that people really used to conduct espionage like this back in the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠day makes it feel all the more impressive.

"You used to like stuff like this, Oppa."

"Yeah. Back then, I seriously thought about joining the NIS because I wanted to do things like this."

"Why didn't you go?"

"The requirements were incredibly high. I knew I’d never make it, so I gave up right away."

"Aha."

"If I had become an agent, I think I would have used a knife instead of a gun."

If I ever had a job like that, I think I’d use a blade rather than a gun. A sword like a katana looks way cooler than a gun, doesn't it?

Was there a sex scene in this? Honey traps appear often, but... usually, they just pounce and finish before the main event. I didn't expect them to actually do it here.

"..."

It wasn't the main focus, just a brief moment, but we stayed quiet for the rest of the movie. It was a good thing Mom had taken care of me earlier; otherwise, I would have been caught already.

"Shall we sleep?"

"Yeah."

I checked the clock; it was past 1:00 AM. Well, we’d checked in after 10:00 PM, so that made sense.

"Good night."

"Yeah."

"..."

Just as I thought we were going to sleep without anything happening, Chaeyu snuggled into me. Then, she naturally placed her hand on my waist.

"I thought you said you were going to sleep."

"I am going to sleep."

Chaeyu’s hand movements were completely different from her words. Starting from my waist, she stroked my stomach, then clung to me and started getting bolder. I don't know when she’d undone it, but my pants zipper was already open.

"Ugh..."

Our lips met naturally. She’d been bold at home, but since we were in a place where there was truly no one else, the kiss became even more daring. It had been a while since Chaeyu had done this while lying down, so her tongue was even more aggressive. My hand naturally moved to Chaeyu’s backside, stroking it. As expected, her butt was soft and full of elasticity.

"I’ve been curious about this for a while."

"Yeah?"

"Why do women touch it like they're tormenting it?"

"Just because. It's fun. And cute."

"Could you please not play around with a man's vital point so lightly...?"

What’s so fun about tormenting a soft cock? From a man's perspective, I really don't get it. What if it gets hard? Still, I was glad I’d taken care of it earlier today.

"Aren't you going to do anything, Oppa?"

"...Do what?"

"I'm playing with you, Oppa."

"Ah... is it okay if I do?"

"...Why are you asking now? You even left Seoul and came all the way here."

"You never know what someone is thinking until the end."

"Dummy."

I climbed on top of Chaeyu and undid her buttons. She must have been prepared, because she wasn't wearing a plain skin-toned bra, but a dark one. ...I feel like I've seen this somewhere before. It feels like someone other than Chaeyu was wearing it...

"Are you a master, Oppa?"

"Why?"

"You undid it in one go."

"How many times have we done this... it's completely ingrained in my body."

Just like how military discipline or disassembling a gun becomes muscle memory, sex becomes ingrained in your body the more you do it. Especially taking off clothes—I could honestly do it with my eyes closed. To be fair, even a beginner could probably take this off immediately.

"Mmng..."

I took off even the bra and greeted her bare breasts. They were the same pink nipples I’d seen last time.

"It's uncomfortable."

"Yeah."

We threw off all the cumbersome clothes. Wearing nothing but our socks, I continued tormenting Chaeyu.

"Ugh, hng..."

Her breasts were voluminous, barely fitting in one hand. I’d only looked at Mom’s breasts, but it had been a while since I’d touched them, so I almost lost my reason. I could have spent over an hour just touching her breasts; I was so happy to see them again.

"What the... it only just got hard now."

"It wouldn't be fun if it got hard right away."

"Ugh...!"

From top to bottom, I scanned and moved down Chaeyu’s entire body. Perhaps because we’d overlapped our bodies countless times, there was absolutely no physiological resistance. If anything, it felt like my instinct to mate was coming even more alive.

"Hah, ahh..."

As Chaeyu’s moans grew louder, she started to writhe. Every time I heard those lewd moans, I felt something gathering at the tip of my glans.

"Op, pa..."

"..."

If it had been Miu-noona from before, she would have asked who "Oppa" was, but now that I was actually her Oppa, it made me even more excited. I pulled off the panties I’d been planning to enjoy slowly later.

"Hng..."

I pulled Chaeyu’s waist close enough for my mouth to reach and stuck out my tongue. She must have used the feminine wash just a moment ago, as there was an artificial scent. But that scent lasted only a moment before it changed into a rich, thick aroma.

"Slurp..."

I gave her pussy a deep kiss, releasing the instinct I couldn't resolve with Mom. This feeling of being tightened from all sides is something I haven't felt in a long time. Chaeyu twitching as she moaned, and the juices flowing according to those movements. I was so happy to be back.

"Slurp."

"Haa..."

Her pussy was already quite wet, enough that just rubbing her labia produced arousal fluid. Before inserting my cock, I inserted a finger to check her condition. Even though it had been a while, she was quite active and warm.

"What the... when did you buy these...?"

"They were at home. I got tired of buying them every time I met you, so I bought a whole box."

"So that's why..."

Instead of the thick, subpar motel condoms, I put on a thin, sturdy one. It had been a while since I’d worn a condom, so it felt a bit tight. Thinking about how long it had been, I didn't have time for games and immediately brought my glans to her pussy.

"Oppa."

"What."

Chaeyu pretended to resist, pulling her legs together. But in reality, she was just lifting her waist to make it easier for my glans to fit.

"Are we really doing this...?"

"What are you talking about all of a sudden?"

"Something... I'm scared. It feels like there's no turning back now."

"..."

"We shouldn't be doing this..."

"...It's already too late to say things like that, isn't it...?"

She was the one who said she’d take care of me in the first place. She should keep the words she spits out. Just like we did every day, when she was my cock-sleeve.

"Ugh... it hurts..."

"Does it? Is it because it’s been a while?"

"Yeah... I think so."

"Then I'll move slowly."

"Okay..."

I moved my waist slowly and kissed Chaeyu again. As our tongues became stickier and more deeply intertwined, the tension in our bodies eased, making it easier to move.

"Mm... hmph..."

I focused all my nerves on my waist and tongue, exploring Chaeyu from top to bottom. Chaeyu pleased my body with her mouth and pussy, while holding me with her arms and legs.

"Ugh, hng, ah, hah."

"You seem to have become more spoiled?"

"Oppa, you're..."

When she was Miu-noona, she always had a relaxed attitude. But today, she had devolved into a younger sister who just moaned and acted cute.

"And this... since it's been a while..."

"Didn't you do it by yourself?"

"How could I when you were there..."

"You could have done it when I wasn't around."

"..."

"Honestly, have you done it or not since you moved in?"

"...I have."

"What the. You did it, huh."

"But that and this are... completely different, ah!"

Suddenly, my waist started moving faster. Imagining my younger sister masturbating in secret at the house where I lived made me even more excited. What did she use for her fantasies? Personally, I hoped it was me.

"Hah... ugh...!"

"I think I'm going to cum."

"Cum ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠for me..."

"Tsk..."

Because Chaeyu whispered in my ear, I ejaculated. Had the cooldown for the ejaculation I had during the day already passed? It felt like I’d cum quite a lot. The feeling of the gush seemed to flow backward through the condom.

"Are you satisfied today?"

"...Yeah."

"What the. Why has your reaction become so cute?"

"Because you're my Oppa."

"...Are we doing it again?"

"Can you...? You usually finished after one or two times..."

"I told you. I’ve been pent up."

Provoked by Chaeyu’s not-so-subtle challenge, I flared up for a moment. I turned that cute body of hers around.
