The First Kiss
The memory floating through my head guided me. I moved my lips the best I could. I was so nervous I couldn’t even tell if I was kissing her or just doing some weird mouth exercise.
“Ugh…”
“Ah.”
I tried to open my mouth wider and go deeper, but our teeth clacked together. Normally when people went in hard like that, teeth didn’t collide. Maybe those people in the stories were just pros.
“That hurt.”
“…I’ll make sure it doesn’t hurt this time.”
This time I slowly enveloped my older sister’s lips. I tested the waters with careful, almost-biting movements, watching her reaction. The way she awkwardly matched me told me it didn’t hurt. People always said kissing felt good, but I was too tense to feel anything pleasant. Still, the way my cock had gotten rock hard proved my body was enjoying it.
But when do I put my tongue in…?
A kiss wasn’t just mashing lips together. It was a noble yet filthy act of exchanging saliva with your tongue. But I’d read way too many stories where guys just shoved their tongue in and got called disgusting, so I had no clue how to proceed. Where the hell was I supposed to learn something like this—
“…!”
While I was still debating what to do, something that wasn’t my sister’s lips touched mine. It only brushed against me for a second before pulling away.
“…How was that?”
“…It was… something.”
“Yeah. It really was something.”
It felt good, but not that good. At the same time, I didn’t hate it. It was just a lot harder than I’d expected. There had to be some reason we were doing this.
“Should we stop?”
“…I don’t want to.”
“Then… one more time?”
“Yeah.”
I closed my eyes again and focused. This time I didn’t overthink where or how. I just went with whatever felt right. Theory and practice were different anyway. Since I’d never actually learned any theory, I decided to just smash my body against hers.
“Mmph… slurp…”
I sucked on her a little harder. Not to make her feel good, but until I was satisfied. I thought only of myself and surrendered to pure instinct.
“Ugh, haa…”
My body grew hotter. My stiff lips gradually loosened, and faint moans began to slip out.
“Sluuuuurp…”
“Hngh…!”
I was sucking on her lower lip when, without thinking, I slipped my tongue inside. I pried open the entrance her teeth had been guarding and fully opened her mouth. That was when I finally heard the sound I’d read about so many times—the wet, sticky sound of two people devouring each other, saliva mixing, mouths smacking. Our lumps of desire intertwined, and that passage bound us together.
“Haaang!”
I couldn’t stay like this forever. I lifted my body and looked down at her from above. Her face had gone completely slack, lips slightly parted. A thin trail of drool was leaking from the corner of her mouth.
“Slurp…”
I pressed my body against hers again and kissed her once more. Now that the tension had melted away, I could finally feel it the way everyone described. So this was why kissing felt so good. I finally understood why so many people preferred it over sex.
“Haa…”
When we separated again, I realized I was holding her tightly. My knee had slipped between her legs, and her clothes were so disheveled that her bra straps were clearly visible.
That thing from back then…
The see-through underwear I’d seen at the convenience store, the one that showed off her ass completely. The kind where you could probably even see her pussy if you were lucky.
“…Jiyun.”
“…Yeah.”
“Mmm.”
My sister let out an adorable little sound and stretched her arms above her head. Her t-shirt rode up, revealing a sliver of her navel.
“……”
There was no more reason to hesitate. I grabbed the hem of her shirt and pulled it up. The more soft skin I revealed, the harder my cock throbbed and twitched. Fuck, what the hell do I do with this? I really can’t hold back anymore. At this rate I could probably recite every single post she’d ever written as a Pa-ttak.
“How… does it… look?”
I tossed the removed t-shirt onto the floor. I’d seen her upper body once before when we switched positions, so I had a rough idea, but seeing it again in person was on another level.
“…How do I take this off?”
“With your hands.”
When I held out one hand, she took it and guided it behind her back. I fumbled around following her lead until my fingertips found something hard.
“Just undo this.”
“…What if it rips?”
“This one’s expensive, you know?”
“Ugh—”
When I tried to sit up, she climbed on top of me instead. Thanks to that, undoing the hook became much easier.
“It won’t rip now, right?”
“Yeah…”
When I sat up, her breasts filled my entire field of vision. Just looking at them sent chills down my spine.
Whoa…
It was my first time hugging her completely bare. She felt even more delicate than when I’d held her during the kiss. Had my sister’s waist always been this thin? It fit against me so perfectly it was like we were made for each other.
“Done.”
“You’re good at that.”
“I was being as careful as possible…”
When the hook came undone, the back fell limply. The straps slid off her shoulders. If she let go of the cups she was clutching to her chest, they would be completely exposed.
“Have you… ever seen breasts before, Pa-ttak?”
“You’re suddenly going full moderator mode…?”
“Answer me. Quickly.”
She desperately guarded the cups while questioning me. It seemed like she wouldn’t show me unless I answered.
“…Yes. In videos.”
“No. I mean my breasts.”
“……Yes.”
“When?”
“……Am I allowed to say?”
“Yes.”
“……About two weeks ago.”
“…What?”
Her lips began to tremble. She covered her face with the hands that had been hiding her chest. Unfortunately, her elbows were still supporting the cups, so I couldn’t see anything.
“…How?”
“……Do I really have to say?”
“……Yes.”
“For real?”
“…Is it that embarrassing?”
“It’s a little embarrassing, yeah…”
In truth it wasn’t a little—it was incredibly embarrassing. Especially since I’d watched her masturbating completely openly. I’d seen more than just her breasts; I’d seen everything. But she never noticed a thing.
“……Ah.”
“It was… that time you came home early from work—”
“I get it, so don’t say it.”
“…Okay.”
“Ugh…!”
“Ow. That actually hurts.”
Apparently mortified, she started smacking me for real. These weren’t light taps—she was hitting the desk with enough force to make it bang. Honestly, if I were her I’d want to die from embarrassment too.
…Wait, did she catch me too?
“Ah.”
While she was hitting me, her bra finally slipped off with a soft plop. It was too dark to see clearly, but the moment I caught sight of her nipples again, she frantically covered her chest.
“…Why, why didn’t you say anything…?”
“How was I supposed to say something like that…?”
Just like how parents usually pretended not to see their children’s private moments, it was only natural for family to look the other way. Since we had to keep seeing each other, there was no way I could leave her with that kind of humiliation.
“I want to die.”
“…Don’t say that.”
I gently pulled her into my arms. She finally lowered her hands and hugged me back. I couldn’t see them, but the soft pressure of her breasts enveloped me.
“…What did you think?”
“……”
“Tell me already. You said you saw everything.”
“……I jerked off to it.”
“…You did?”
Since I’d confessed her embarrassing secret, it was only fair I confessed mine. I told her that seeing her like that had turned me on so much I’d masturbated. I didn’t dare mention that I’d also stolen her panties and done even worse things.
“……Do you want to see?”
“Yeah.”
“I want to see yours too.”
She pulled back and started taking off my clothes. Since I wasn’t wearing a bra, my bare torso was immediately exposed. Her palm rested on my stomach.
“…It’s so hard.”
“Because I’m flexing.”
Her gaze fixed on one spot. Not on my shy, embarrassed face, but on the natural teardrop-shaped mounds of fat that had been tormenting me all evening. I was finally seeing the breasts that had been driving me crazy up close.
“Jiyun, you have a nice body.”
“…What did you say?”
“…Nothing.”
My heartbeat was so loud I could barely hear her whisper. So this was what breasts were really like when you saw them this close.
“Hngh…?!”
When I came back to my senses, my face was already buried in her chest. The scent of body wash and something lewd rose up at the same time. Her breasts pressed against both sides of my face.
“What are you—ugh, mmph!”
She tried to push me away, but her strength was laughably weak. Instead, I pushed her down and placed my hands on her breasts.
“Haaah…!”
While she covered her mouth, I began to touch her chest. They fit perfectly in one hand. Yet they were so soft I couldn’t help but handle them carefully. Without even realizing my mouth was open, I started moving my hands over them.
Fuck…
I desperately swallowed the curses that kept trying to escape. They felt like they would burst if I applied even the slightest pressure, so I couldn’t even knead them properly. For now, just touching them freely was enough to satisfy me…
“Mmph!”
No. There was no way I could hold back. Leaving something like this right in front of me and doing nothing was something only a eunuch would do. Just like when we were kissing, I decided to slam my desire into her. I gathered my courage and grabbed her trembling breasts with both hands.
“…Haa.”
“It… tickles…”
The moment her breasts moved according to my will, the last thread of my reason snapped. When I squeezed hard, she shivered violently. When I rolled her nipples between my thumb and forefinger, she let out small, adorable sounds. The first breasts I’d ever touched belonged to my own older sister. Even though I knew that continuing to commit this taboo would eventually bring karmic retribution, my desire refused to stop.
“Haa… Jiyun, wait, just a sec—”
“……”
“Mmph…”
“Ah… yeah.”
Only after she gave me a deep kiss did I finally regain my senses and stop. She covered her breasts again—the ones I had already groped and flicked.
“My heart feels like it’s about to explode… I’m scared.”
“……I can’t hear anything because of my own heartbeat…”
“Yeah… Let’s calm down a little.”
We breathed together, taking deep breaths to steady ourselves. Once some of the blood that had rushed to my lower body returned to my brain, I remembered that Mom was still in the house.
Creak.
“…?”
Feeling something cold and wet, I looked down. At some point our lower bodies had been rubbing together perfectly, and my pants were now stained.
“What the…?”
“……”
When my sister slightly lifted her body, the warm heat that had been pressed against me disappeared. We both stared intently at each other’s pants—me at hers, her at the tent in mine. It reminded me once again that the main event of sex wasn’t breasts.
“Noona.”
“Jiyun.”
“Ah… you first.”
“…Okay.”
She stood up, carefully put her t-shirt back on without bothering with the bra. I followed her lead and got dressed again.
“I really don’t think I can hold back anymore.”
“…Me neither.”
“Right now I want to strip you completely… but if I do that Mom will wake up…”
“I feel like I’d end up just pounding into you without being able to stop…”
“…Pervert.”
“You’re one too…”
If that happened, Mom would catch us. We couldn’t let that happen. She could never find out that her only son and daughter had fallen this far.
“Anyway… that’s why I… made a reservation. I actually came here to tell you about that…”
She took out her phone. When the screen lit up, I could see how intensely red her chest had become.
“What…?”
“The place where we slept together last time.”
“…The motel?”
“Somewhere better.”
“A hotel…?”
“Yeah. That’s why I couldn’t buy you a hamburger earlier… Sorry.”
When I saw that the price per night was over 300,000 won, it all made sense.
“So… when you get off work today… let’s go. Since it’s Friday.”
“…Okay.”
I nodded. She carefully stood up. I wanted to kiss her again, but I knew I wouldn’t be able to stop myself, so I held back.
“And… I saw you doing it by yourself too.”
“……”
She scurried away like a little mouse. After hearing those words, I immediately gave up on the idea of jerking off right then. I’d save it for tonight at the hotel.
