Chapter 69: Gym (6) ♥
Back in the bathroom where we’d already done it once, I was dragged inside by the wrist. As Kang Yu-min pulled me in, I found further confirmation of her fetish.
“Hey, all of a sudden…”
Before I could even finish my sentence, Yu-min pinned me against the wall. As my back hit the surface, she was already buried in my chest, taking a deep, shaky breath.
The ticklish sensation of her breathing stimulated my chest, and her hair fell over my muscles and skin, which were flushed with sweat and heat.
The feeling wasn't bad at all.
Her sweat-soaked hair should have been unpleasant, but it wasn't. Her breath was ticklish, yet it didn't feel gross.
If anything, it was a turn-on. It’s not like I have a sweat fetish myself, but...
The realization that we were doing something undeniably lewd hit me anew. Perhaps it was because a drenched Yu-min was pressed so tightly against me.
The feel of her ample breasts, her soft skin, and the sticky texture of the sweat coating her made the blood rush straight to my crotch.
My cock was already reacting to what we’d done earlier.
It swelled as I recalled the sticky, blissful sensation of Yu-min’s mouth.
Seeing her looking so lewd, as if she were in heat because of me, made the pre-cum leak out.
I let out a faint groan as I rubbed my cock against Yu-min’s exposed, sweat-slicked abdomen.
We had done this several times already, but maybe it was because we were in a public place.
Thinking that I shouldn't be doing this while simultaneously knowing how good it would feel, I stood still and let Yu-min lift my shirt.
She rubbed her lips against my bare chest.
She rubbed her legs against mine, making wet, squelching sounds, while one of her hands reached into my waistband to rub my glans through my shorts.
Meanwhile, she used her other hand to pull my hand toward her and place it over her pussy. Panting, she licked my chest and kissed me.
Everywhere her tongue passed, leaving a trail of wet sounds, it left behind saliva so hot it felt like it was melting me.
She was acting without a shred of reason, simply throwing her raw lust at me. Watching her like that, the words slipped out of my mouth.
“Do you… like the sweat?”
Yu-min’s clouded pupils turned toward me.
“I like you.”
That was the answer she managed to squeeze out. My hand, which had been reflexively massaging her pussy through her leggings, stopped. I found myself intoxicated by her dazed smile.
This crazy girl, seriously.
It made no sense to get turned on by the smell of sweat while working out with her brother.
Even as I thought that, I wasn't exactly free from it myself.
I had never seen Yu-min like this. Her pussy juice was flowing so heavily it left a vivid stain on her leggings, and she smeared the scent of it onto my fingers.
“Liar,” I said.
Yu-min’s breathing hitched for a moment.
She looked up at me with narrowed eyes. They were sharp and filled with deep irritation, but beneath that, there was a sense of being wounded.
I looked her straight in the eye and continued.
“What you really like is my cock.”
At that, her expression softened. Exhaling a ragged breath, she tightened her arms around my waist, pulling me even closer.
“No, that’s not it. I…”
“Then what’s this?”
I held up my fingers in front of her eyes, and her pussy juice stretched stickily between them.
Yu-min reflexively swallowed hard at the sight. I pressed the point home.
“Did it feel good licking your brother’s sweat? Were you imagining getting plowed while soaked in sweat, your pussy dripping wet?”
“That’s… not it…”
“Don’t lie. You should be honest with yourself.”
Her limbs flinched. Her pupils trembled. Tears welled up in her eyes as if she were about to burst into a sob, but I knew it wasn't from sadness.
I moved my arm to cup her ass. Her body stiffened as my hand slipped inside her leggings, but she didn't push me away. That was all the confirmation I needed.
I squeezed her voluminous butt cheeks, and a sharp intake of breath tickled my neck.
“You just want to get fucked senseless by your brother’s cock. You perverted Noona.”
As I parted her butt cheeks and started teasing her pussy with my index finger, Yu-min buried her forehead in my chest and breathed heavily.
I could feel her racing heart through my chest, and my hand, still parting her backside, felt the endless flow of her juices.
What Yu-min wanted was clear. I knew it, and she knew it too.
We had lived as siblings for too long not to know each other. I pinned her against the wall for support and pulled down my shorts.
“Y-you…”
“What.”
She looked at me with tearful eyes. Her obsidian-like pupils spilled over with tears, and I smirked at the sight.
“Only at times like this… you play the… Noona card… it’s unfair…”
“Then don’t be so damn hot, Noona.”
When I pressed my body against her, pinning her to the wall, she let out a soft moan and writhed.
“I can’t… breathe.”
“You like that, though.”
“No, I—ah!”
“If not, then what’s this? Your pussy is going to prune my finger.”
Beyond just teasing her, I pushed my finger inside. Her pussy walls clamped down on it as if it were a cock. Having tasted her many times before, I was familiar with her pussy, and I traced the ribbed interior with my fingertip.
That alone was enough to make her waist go limp. Her exposed stomach twitched as she shuddered. She tilted her head back and covered her mouth to stifle her cries. It was so cute that I began to stroke her labia and ran my finger down toward her perineum.
“Ngh, hng, ah, mmm, hng.”
Her moans were muffled by her hand. But her tear-filled eyes were already overflowing with pleasure.
The sensation was contagious. As if infected by her lust, I bit her neck and pressed my body harder against hers.
“Smell it. Right now.”
“I… hate it.”
Despite her words, Yu-min hugged me tightly. She licked my sweat-drenched skin with her long tongue in a vulgar display, taking deep, gasping breaths in between.
The breath tickling my skin felt scorching hot. But it wasn't the unpleasant heat you feel walking outside in the summer.
Instead, a sense of fulfillment filled me—the kind you only feel when you’re slamming your cock deep into a pussy, the pubic hair tickling the mound.
This is mine. This pussy, even this uterus—it’s all mine.
Since things were already ruined, why hold back? With that firm thought, I lightly bit Yu-min’s ear. She couldn't decide whether to push or pull my arm, so she just held on and cried out like a female in heat.
With every breath, Yu-min filled her nose with the scent of my sweat, her thighs trembling as she prepared to welcome the cock that was about to conquer her.
Her drenched leggings were so sticky they felt like they would tear as I pulled them down.
Once I finally managed to get them off, Yu-min desperately spread her legs.
“Don’t… do it…”
She let out the ritualistic protest as if it were expected. It was utterly hypocritical, yet somehow lovely at the same time.
It was as if she knew exactly what turned me on and was doing it on purpose.
Maybe she wasn't, but I decided to play along with her little game.
After all, in times like this, it’s only right for the man to give in.
“Then don’t act so tempting. This is your fault, Noona, so take responsibility.”
“Ngh, hng, haa.”
A moan that sounded almost like a laugh escaped her. Yu-min closed her eyes tight at my words and pushed her hips forward slightly. I pressed my exposed cock against her pussy.
I smeared her juices over the glans, leaving a sticky trail, and she accepted the head of my cock with a rhythmic tilt of her hips. The sharp gasp she let out was deeply satisfying.
It meant that this woman—who had never known a man and had never touched me because I was her brother, despite her feelings—was still overwhelmed by my size.
It felt like being the first to step onto a pristine field of snow with muddy feet.
Amidst the thrilling pleasure, I thrust my hips while standing.
“What are you doing? Hurry up and move your…”
My smirk suddenly vanished. Yu-min and I both seemed to snap back to reality at the same time. We turned our heads simultaneously toward a specific spot.
It was my smartphone, tucked inside the locker right next to us.
The default ringtone, which I hadn't bothered to change, was blaring.
I locked eyes with Yu-min. My cock twitched inside her as I reached out, almost possessed, to open the locker and grab the phone.
“…It’s Eldest Noona.”
Her pussy, which had been greedily milking my urethra, seemed to reach out even further. My hips bucked at the sticky, licking sensation, but I kept my eyes on Yu-min.
She looked slightly terrified, her waist trembling, yet her expression was that of a female desperately begging to be filled.
Seeing that, I couldn't wipe the smile off my face.
“H-hang up… quickly… ah?!”
Yu-min’s eyes went wide as her body jolted. I thrust my hips upward, and as her vaginal walls clamped down in a climax, I let out a thin groan.
“Ha… this is delicious. Seriously.”
“Ngh, hng, ahhh, mmm!”
She shuddered in the throes of her orgasm, her pussy pulsing around me. I watched her intently, then suddenly held the phone up in front of her eyes.
“Yu-min, look at me.”
And when her confused eyes met mine.
I put the phone to my ear.
Realizing the situation, Yu-min squeezed me as if she wanted to snap my cock off at the root. I winced at the sheer intensity of the pressure.
She looked at me in horror, as if asking what the hell I was doing, biting her lip and trembling as she silently begged me to hang up.
At the same time, the violent clenching of her internal muscles made her excitement visible.
She looked like she was about to moan and climax again at any second, but as she tried to hold it back, she twitched with a tearful face.
It would have been fun enough just to stay still, but I slowly began to move my hips up and down.
I moved slowly enough so the wet sounds wouldn't be heard, but with enough depth to bring both Yu-min and myself to the brink.
Yu-min finally couldn't take it and covered her mouth with her hand, her body jerking. I answered the call while continuing to fuck her.
[Hello? Jin-ah?]
The moment I answered, Eldest Noona’s elegant voice filled the shower room through the speaker.
Naturally, Yu-min’s pussy wrapped around my root and wouldn't let go. Even so, I forced my hips to move as I exhaled a faint breath, and a very muffled moan escaped from behind her hand.
The electric stimulation seemed to seep into my brain. I reflexively closed my eyes, trembling as I clamped my jaw shut.
I wanted to cum. No, I had to cum.
Looking at Yu-min, who was shaking her head as if begging me to stop, I couldn't hold back and gave a massive thrust.
A wet, squelching sound rang out. Yu-min clamped both hands over her mouth to stifle the scream that wanted to burst out.
As she hit another climax and her pussy pulsed rhythmically, I pushed past the walls to her deepest point and ejaculated.
The semen poured out in thick, heavy bursts. As it filled her, Yu-min’s eyes rolled back. Her legs shook, and her toes curled and uncurled repeatedly against the tiles.
And so, we both leaned against the opposite walls of the changing room, panting and completely joined. We painted each other inside and out with our fluids, engaging in a vulgarity that even lovers would hesitate to perform.
Still breathing hard, I barely managed to hold onto the smartphone that felt like it was about to slip from my hand.
[…Jin-ah?]
I couldn't answer immediately. I tried, but I was afraid my ragged breathing would give me away.
I took a moment to catch my breath, forcing myself to sound normal.
“Yeah, Noona.”
At my strained response, Yu-min’s pussy gave a series of tight squeezes. I barely suppressed a groan as I shifted my hips.
The slow movement created a sticky sound as the semen and pussy juice mixed. I moved even more slowly and deeply to hide the noise.
“Why did you call?”
Tears streamed down Yu-min’s face as she pulled her hands away from her mouth and began to move her own hips.
“I was just working out with Yu-min.”
The moment her name was mentioned, I felt her pussy—the pussy of a sister reserved only for her brother—clamp down hard. I smirked.
What a slut.
The shower room was filled with the wet sounds of our union and the voice of our eldest sister.
