Semen Lotion (1)
"...Oppa...! Oppa...! Ugh, wake up already!"
The sound of my little sister violently shaking me awake from the crack of dawn forced my bleary eyes open.
"Mmm... What's the matter, Seo-ah...? Did something happen...?"
"Ugh, if your eyes are open then get up! It's your fault we're running late!"
My sister yanked my arm and forcibly hauled me upright, yelling in irritation.
'What the hell is this chaos so early in the morning... again...'
Once I finally regained my senses and looked at her, I saw that my sister had apparently just stepped out of the shower—her hair and entire body were soaking wet.
I snapped wide awake in an instant. My eyes bulged as I stared at my sister standing there with her bare skin completely exposed, and I shouted.
"Hey...! What the—what are you doing? Why are you like that...!"
Anyone with a little sister would probably understand, but this was the kind of event that could flip the entire world upside down.
Like most twin siblings around the same age, my sister and I had never been particularly close.
Ever since puberty, she had developed a visceral hatred for me even approaching her room.
Naturally, the idea of her casually showing off her naked body like this had never once occurred in my memory.
Yet my sister looked at me as if I was the strange one. She placed one hand on her hip, furrowed her brows, and tilted her head with casual bewilderment.
"...What? Why are you staring at me like that? Are you that annoyed I woke you up? You have to get up soon anyway... Whatever. I need to apply lotion before my skin dries out, so hurry up and give it to me."
She crossed her arms with a pouty expression and snapped at me.
I was so stunned by her nonchalant attitude that my mouth refused to open.
'Wh-what the hell is happening right now? Why isn't she embarrassed at all to be standing in front of me like this...? Am I dreaming...?'
As I stammered without answering, my eyes shaking wildly, my sister finally ran out of patience. She flipped her wet hair back, stepped forward, and ripped my blanket off in one swift motion.
"H-hik...! What are you doing...!"
Naturally, having woken up to the sight of my sister like that, my cock was rock-hard, straining against my pants as if it might burst through any second.
But instead of being horrified, my sister smiled in satisfaction and said exactly this.
"Oh, thank goodness. I was worried I'd have to get it hard first... Here, give me your semen. I need to apply it quickly and dry my hair."
Without hesitation, she reached out, yanked my underwear down, grabbed my fully erect cock, and began stroking it up and down with indifferent, mechanical motions.
"H-hik...! Wh-what are you doing right now!"
Of course I panicked and frantically swatted her hand away.
I scrambled backward as if I'd seen a ghost.
My little sister—completely naked, casually giving me a handjob first thing in the morning.
This couldn't be reality. So it was one of two things: the girl in front of me was a ghost in disguise, or this was all one giant dream.
I decided the latter was far more likely, squeezed my eyes shut, and pinched my cheek hard with my fingers.
"Ow...! Th-this is weird. It hurts..."
While I was doing that, my sister finally exploded with frustration.
"Ah, seriously, what are you doing? You've been pissing me off since earlier! I have to get ready to leave. If you keep wasting time, I'm going to be late!
What's the big problem with me putting some of your semen on my body? Just cum already, damn it!"
"Wh-what...? No, what the hell are you even..."
...Judging by that sharp tone and the rude way she was snapping at her own older brother, it really did seem like the sister I knew.
But the words coming out of her mouth refused to compute inside my head.
'She's going to put my semen on her body...? Why the hell would she do that...? What is going on...'
But whether it made sense or not, the scene unfolding right in front of me was undeniably real.
My sister huffed angrily, cornered me against the wall, and began stroking my cock roughly with her soft hand.
"U-ugh.... ngh.... S-Seo-ah..."
I mumbled pathetically toward her, but she simply looked down with an indifferent expression and focused entirely on jerking me off.
After about three minutes, she started getting visibly impatient. She glanced at the clock and burst out irritably.
"...Haah, are you doing this on purpose, oppa? Why is it taking so long! I'm really going to be late!"
"Ah... s-sorry.... ngh...!"
When I apologized in a daze, she shot me a look of pure disdain, clicked her tongue, then bent at the waist and gently pressed her tongue against the tip of my cock.
I widened my eyes in shock, bracing my hand against the wall as a moan escaped me.
"Wha—!? Seo-ah...? Where did you learn to— haa...!"
She glanced up at me, then began licking and probing at my urethra with the tip of her tongue in quick, teasing strokes.
At the same time, her hand continued relentlessly squeezing and stroking around the rim of my glans.
An icy-hot pleasure immediately surged from the tip of my cock all the way to the top of my head.
"Lick... lick.... lick lick lick lick lick..."
"Ngh..... ugh, kuh..... Ah, aaah..... S-Seo-ah, you can't—!"
When I lifted my heels, trembling as I tried to hold back my orgasm and pressed down on her head, she glared at me sharply. She flipped her hair back, looked up, and muttered.
"...Ugh, come on! Stop holding it in and just cum on my face already! I'm late!"
"U-ugh...! Kk....!"
At the same time, she gripped my cock even tighter and pumped it harder.
The pleasant scent of shampoo drifting from her freshly showered hair,
the immature feminine scent rising from her damp, glistening body,
her youthful breasts and nipples visible between strands of her hair,
and the obscene sensation of her small hand tightly gripping and shaking my cock—
finally pushed me past the point of no return.
My hips jerked uncontrollably back and forth as I erupted with thick, yellowish semen in powerful, rhythmic spurts.
"Agh...! Ah, ah!! Cumming...! Ugh, ugh, aaahhh...!"
An indescribably massive wave of pleasure flooded my mind with pure white.
The sight of my little sister—who had always ignored and despised me—willingly turning her own face into a cum rag while indifferently jerking me off was the ultimate taboo pleasure I would never feel again in my life.
The semen I had blasted with all my strength covered her entire face, splattering into her nostrils and mouth without mercy.
Even afterward, more semen continued pouring out like milk from my cock, soaking her neck, collarbones, and fully exposed breasts.
My sister didn't seem to mind at all that my semen was all over her face and body. She squeezed out the very last drop with careful, firm strokes.
Finally, after the long ejaculation that had lasted nearly a full minute ended, she wiped the remaining semen from the glans with her hand and casually rubbed it along her arm as she muttered.
"...Haah, you really let out a lot. Did it feel that good? Well, it works out for me. I can apply plenty."
"Haah, haah, haah.... Wh-what the hell... why are you doing this..."
I muttered in genuine fear as I watched her calmly spreading the semen I had just ejaculated all over her body and face.
She widened her eyes and shrugged.
"Huh...? What are you talking about? Are you stupid, oppa? Isn't it common sense that men's semen is good for the skin?"
"Wh-what? Common sense?"
When I shouted back in disbelief, she frowned as if thinking 'Is he really an idiot...', gave me a once-over, and finally turned away curtly.
"...Anyway, I'm leaving now. Get ready on your own, oppa."
Just as suddenly as she had appeared, she left the room in a flash.
I remained frozen for a long time with my mouth hanging open, staring blankly at the empty space where my sister had been.
'Wh... what the hell is going on....'
It didn't feel real at all.
I stared dazedly down at my cock, still glistening with the sticky remnants of my ejaculation, before suddenly remembering something. I quickly pulled up my pants and looked around frantically.
"...Th-this is definitely it. The thing I've only heard about in rumors—Common Sense Alteration—has happened... There's no other way to explain this..."
I hurriedly grabbed my phone.
I didn't know how far this Common Sense Alteration had spread, but there were probably others like me who had woken up to this kind of shock.
I quickly opened various community sites on my phone, searching for anyone sharing similar experiences, but shockingly, in the vast expanse of the internet, not a single person was complaining that anything was strange.
I broke out in a cold sweat and muttered to myself.
"...N-no way... Does this mean everyone except me has been affected by the Common Sense Alteration...?
Wh-why am I the only one left out....?
....No, that's not what's important. What the hell am I supposed to do from now on..."
I clutched my head in confusion when I suddenly glanced at the clock and realized I was on the verge of being late. I jumped up in panic.
"Ah, shit... I-I have to get to the academy right now."
I rushed out without even washing up, threw on some clothes, and sprinted toward the cram school.
"Huff, huff.... I almost... was late...."
The moment I arrived at the classroom, opened the door, and stepped inside, I was once again struck with shock and froze solid.
'...Huh...? Why am I the only male student here...?'
