Have You Ever Smelled Cum Before?
My older sister’s pupils trembled without pause. It was the complete opposite of that middle school moment when I’d been caught holding her panties in panic. The difference was that, unlike back then when I’d desperately tried to clear up the misunderstanding, she had frozen on the spot like a criminal caught red-handed.
“Y-yeah, this is, um… that is….”
“What are you doing over there?”
“No, I mean….”
She couldn’t hide the underwear she was clutching, nor could she show it. She was completely at a loss. Even then, her shaking eyes refused to stop.
“Noona, come out of there first.”
“….”
“Leave the panties there.”
“Ah, uh….”
I sat the guilt-ridden sister down on the living room sofa. While I stood across from her looking down, a heavy silence filled the space between us.
“You were just smelling my underwear, weren’t you?”
“That’s… I’m sorry.”
Still unable to meet my eyes, she hung her head low.
“I don’t even know why I did it. When I came to my senses, I was already there. It sounds weird, but it’s true….”
I had expected Lee Seo-noona to confess honestly. Just like she’d always been with me, she was the type who clearly expressed her dislikes but never cowardly hid her own mistakes.
“I’m sorry.”
She apologized again, this time with genuine remorse. She could have tried to downplay her fault by bringing up what I’d done in the past, but there wasn’t even a hint of that in her.
“Why did you smell it? Did you really do it without thinking?”
“I-I don’t know. Your room was filled with your scent, so my head felt like it was floating and my body started acting strange….”
As she mumbled, the corners of her eyes grew wet with shame and guilt.
…So it’s real.
A chill ran down my entire body. Just as I’d written in Sexmuwiki, my sister had developed a sexual fetish that made her drawn to my body odor. To the point where she would willingly sniff a man’s underwear—the same man she used to hate.
Even now she was trying to hide it, but the tips of her ears and her cheeks were flushed red, and rough breaths kept slipping through her lips.
With just this app….
Not only could I fix my relationship with Lee Seo-noona, I could make every male fantasy I’d ever imagined come true. I wanted to open the memo app right then and start writing a bucket list, but there was something more urgent to deal with first.
“….”
She was shrinking in on herself like a student dragged into the police station. The “I don’t know why” part probably wasn’t a lie. Since I’d written in the wiki that she would “go into heat so strongly her reason flies away,” she must have been unconsciously drawn to my potent scent.
If that was the case, what would happen if she smelled something even stronger than underwear?
The next question came from that very curiosity.
“So in the end, you smelled it because you like my scent?”
“….”
“Want to smell more?”
“Huh? What did you…?”
“If you’re okay with it, I’ll let you. Something with a stronger smell.”
The words carried an obviously sexual intent. Yet Lee Seo-noona, whose reason really seemed to have shut down, didn’t frown or curse at me.
“C-can I really?”
“Yeah. It’s not hard.”
Seeing her cooperate in a way she never would have normally, I took one step closer to the sofa and thrust my hips forward. Once again, instead of getting angry, her eyes locked firmly onto my crotch.
“This is probably where it’ll be strongest. If you don’t like it, you don’t have to smell it.”
“….”
Before I knew it, her eyes had grown hazy as she reached out and grabbed my pants. Without me even asking, her pale hands pulled my pants down and slid my underwear off too.
“Haaaa…”
The moment the scent trapped in my clothes was released, her body trembled like a drug addict tasting pleasure for the first time in ages. Just to be clear, I’m someone who washes thoroughly every day. She was simply reacting this extremely because she’d become addicted to my body odor.
Anyway, now that she no longer needed to hide her arousal, her breathing grew much rougher than before.
“Haa… this smell…”
My cock was still hanging limp. Just imagining pulling my pants down in front of another woman would normally get me hard, but now that it was actually happening, I was too nervous to get it up.
“How is it? Is it okay?”
“Huh? Y-yeah…”
“It’ll probably smell stronger once it gets bigger.”
“B-bigger?”
“Want to touch it?”
Instead of answering, her hand moved toward my crotch. She formed a ring with her fingers and began gently stroking the head.
“You’ve touched a lot of guys’ things, right?”
“W-what are you saying? This is my first time.”
So my cock was the first one her hand had ever touched. I already knew that from Sexmuwiki, but it still made me strangely happy.
“You’re good at it for your first time. Not scared?”
“You said it would smell stronger once it gets bigger…”
Apparently just stroking the head with her right hand wasn’t enough. She brought her left hand over too and started fondling my balls. Thanks to that, my previously nervous cock stood fully erect.
“How is it?”
“Hngh. The smell is insane…”
“What do you think of how mine looks? It’s my first time showing it to anyone, so I’m curious.”
“It’s really big… and hot… and a little scary.”
Even as she said that, she kept stroking it. Then she brought that same hand up to her own nose.
“Sniff… haaaa… Don’t I look really weird right now…?”
“Yeah. You look really weird.”
If some random woman had acted like this in front of me, I would have called the police immediately. But because it was Lee Seo-noona, whose looks were already idol-level, what I felt wasn’t fear but pure excitement.
“I’m sorry… but I can’t stop.”
“It’s fine. Smell as much as you want.”
I stepped even closer, pushing my hips forward. We were now so close that just a little more and it would touch her nose. The moment I stopped there, Lee Seo-noona surprised me by leaning her face in first.
“I can’t… I really can’t hold back. Sniff… huuaaah…”
The tip of her elegant nose was now pressed against my cock. It was a sacred first for my junior, which had never touched anything but my own hand. But before I could even savor that feeling, my gaze was stolen by the expression on Lee Seo-noona’s face.
“The smell… ngh… hng. Huuaaah… it’s so good…”
With half-lidded eyes, she mumbled while eagerly inhaling. It was a woman’s face I had never seen once in all the years I’d known her. She should have been terrified that the hated man’s scent might cling to her, yet instead of pulling away, she pressed even closer.
“Why am I like this… I can’t stop, haa…”
My cock, pushed aside by her approaching nose, slid across her cheek. Fuck, this is so hot.
The absurd sight of an idol-tier beauty from the streaming world with a dirty man’s cock on her face was enough to drive anyone insane. The soft, warm touch of her skin made me want to go even further.
“Noona. Have you ever smelled cum before?”
“Cum…?”
“Cum smells way stronger than this.”
“But cum is…”
I looked down at her with deep, silent eyes. Having understood my intention, she didn’t refuse. Instead, she wrapped her fingers around my cock again.
This would technically count as a sexual act, but her reason had already been clouded by her craving for my scent.
Schlick. Schlick. Schlick.
Her careful, hesitant strokes felt incredibly good for a first-timer. The clumsy, irregular movements created a strangely addictive stimulation.
“You really want to smell cum that badly?”
“You said… haa… it smells nothing like this…”
“If you use your mouth, it’ll come out faster.”
“With my mouth…?”
It didn’t take her long to turn that hesitation into action.
“Hngh.”
The instant her lips wrapped around the head, it felt like electricity shot through my entire body. The slick, sticky sensation was on a completely different level from her fingers. Then her lips began moving up and down, giving me my very first experience of this pleasure.
“Hngh, slurp… chuup. Hup, ugh, chuup…”
“Kgh…!”
The mouth that used to curse me was now sucking my cock. The eyes that used to glare at me were now sending pleading looks that seemed to beg me to cum.
The feeling of my first blowjob and the situation itself were so surreal that I briefly wondered if I was dreaming.
“Chuup, slurp… ngh… juup, juuuup.”
Of course she was clumsy at giving head. But she didn’t need to be good at all. The way her lips could barely stretch around my thick glans, the way her cheeks hollowed out as she sucked on the shaft, the way her eyes looked up at me with a mix of nervousness and excitement—every single thing about her was driving me wild.
“Lee Seo-noona!”
On impulse, I grabbed her head with both hands and started moving my hips. Even though it was no different from treating a woman like an object, she offered no resistance and simply focused on sucking my cock.
“Ugh! Chuup, huup! Up!”
Slurp, slurp, slurp!
The wet sound of my cock rubbing against her saliva-coated lips echoed through the living room. Every time my glans bumped against the tight entrance of her throat, a small groan escaped my mouth.
“Noona, I’m gonna cum!”
I wanted to cum just like this, but then I wouldn’t be able to let her smell it. I pulled my cock out of her mouth, which was clinging tightly and refusing to let go, and started jerking myself off with my hand.
“Noona, put your hands out!”
Lee Seo-noona obediently brought both hands together and waited. I aimed my throbbing cock at her cupped palms and came hard.
“Huu…”
For some reason, the amount was far more than usual. Enough to pool in her neatly gathered hands.
“Is cum supposed to come out this much? It’s so hot…”
She was even more shocked than I was. Her eyes couldn’t leave the milky puddle she was holding.
“Haa, haa… the smell is crazy. My head feels like it’s going numb…”
She even lowered her head to savor the scent. It looked like the cum might touch her nose at any moment, but she didn’t seem to care at all.
“Cum… so this is a man’s cum. Hngh, haa…”
She was only smelling it, yet her hips were twitching. Just how turned on was she?
And then.
“Slurrrp…!”
Gulp… gulp…!
She brought both hands to her face and drank it all down. Her eyes, now completely empty of semen, stared blankly into space.
“Ugh, khk. I drank the cum… I must really be crazy. Haa, haa…”
Was she seeing hallucinations of walking through paradise right now? Saliva dripped from her open mouth as she panted like a dog. On top of that, her body, which had been sitting primly on the sofa, convulsed nonstop. It looked exactly like she was having an orgasm.
I couldn’t help but be shocked by how much stronger Sexmuwiki’s effects were than I’d expected, and by how much lewder Lee Seo-noona turned out to be.
“Huh…? It’s Mom… Hiiik!”
After checking the vibrating phone, she suddenly shot up from her seat. It seemed Mom had called because she hadn’t come back yet. The sight must have snapped her back to reality.
“Lee Seo-noona?”
“Ah, um… s-sorry!”
She staggered toward the front door on shaky legs. Even as she struggled to open the door, she avoided my eyes. Then, like a criminal fleeing the scene of the crime, she ran out and disappeared.
