The Scent Has Changed
I’m home…
After finishing that strange “date” with Hyuna, I carefully opened the front door and stepped inside. A sharp voice immediately rang out from deeper in the house.
“What the hell? Where have you been? I told you to stay home and guard the house.”
Of course, the owner of that voice was my little sister. She had already changed into her pajamas, arms crossed tightly, glaring at me with a terrifying expression like one of the Four Heavenly Kings.
I had desperately hoped she would come home after me, but sadly the gods had no interest in granting my wish.
As I fidgeted, trying to think of an excuse, my sister snapped at me again.
“I asked where you’ve been! You told me you’d stay locked up in the house! So what were you doing out until this hour?!”
“I-I never said that…”
“What? Are you talking back to me right now, Oppa?”
“N-no… that’s not what I meant…”
I mumbled my answers, completely cowed by how viciously she was coming at me today of all days.
Come on, it’s not like I can’t go out once in a while. Why is she making such a huge deal out of it today…? Do I really have to report my every move to her?
Even though I was grumbling with a sense of injustice inside, I wasn’t brave enough to say any of it out loud.
My sister stood at the entrance, watching me fumble helplessly with my collar. She narrowed her eyes, then suddenly lowered her voice.
“...Who was the girl you were with?”
“H-huh…? U-uh…? T-that’s…”
I flinched so hard I couldn’t answer properly and just floundered. When I thought about it, I hadn’t actually done anything wrong, so there was no reason to be this scared. But my sister’s completely twisted expression explained everything.
From the way she asked, it was obvious she already knew I had been hanging out with another girl. I had no idea how she found out, but hiding it any longer seemed pointless.
I avoided her gaze and mumbled.
“She’s… a friend from the cram school… We ran into each other at the PC café…”
“Then why did you walk her all the way to our front door?”
When my sister pressed me like that, I broke out in a cold sweat and answered in a panic.
“Huh…? N-no, we ended up spending the whole evening together… B-but how did you even know I walked her home…?”
My sister ignored my question completely. She wiggled her finger and commanded.
“Take off your pants.”
“H-here…?”
“I said take them off.”
Her tone was always rather cold when she spoke to me, but right now it felt twenty times icier than usual.
Discarding every last scrap of male pride I had, I obediently followed her order.
The moment my pants came down, my sister quietly gathered her hair and tucked it inside her clothes. Then she knelt, brought her face close enough to my cock that I could feel her breath, and stared at it intently.
“Ugh…”
Of course, after being milked over and over all day, my cock was coated in a filthy mix of precum, cum, and sweat, giving off a pungent stench.
My sister didn’t seem to mind at all. She pressed her nose right against the tip and sniffed loudly, then suddenly widened her eyes and glared up at me.
“...The scent has changed.”
“W-what…?”
“It smells different from this morning.”
“W-what do you mean by that…”
“Did you give your cum to another woman?”
Under her razor-sharp interrogation I broke out in a sweat and stammered.
“I-I didn’t want to give it to her… W-why are you acting like this today, Seoa? You’re scaring me…”
“...How dare a worthless Oppa like you give his cum to another woman?”
It seemed my words weren’t even reaching her ears. Her anger was rising in real time.
I struggled desperately to escape that murderous aura, but she had my cock and balls in an iron grip. There was nowhere to run.
She squeezed my cock with all her strength as if wringing out a wet rag while simultaneously crushing my balls in her fist.
“Haauk…! U-ugh…! Kgh…! Heuk… S-Seoa, please calm down…”
“Shut up, you pathetic brother. I told you not to waste your semen. I’m going to kill you. I’ll crush these balls.”
Then she really took both my balls into her mouth and bit down hard with her molars. The brain-piercing agony was so intense I couldn’t even scream; I just shuddered violently.
“I was wrong, Seoa! I’m sorry! Please forgive me…!”
“Shut up. You have two balls anyway, so losing one wouldn’t matter. If you’re going to keep giving it to other women, it’d be better if one disappeared. Here I go—one, twooo, threeee…”
As she closed her small mouth like she was really about to bite down, I shook my head frantically, gasping for breath as I cried out.
“Wait! I’ll give you ten times as much cum as I gave that other woman! How’s that? Sounds good, right?”
“......”
With my balls still half-clamped between her teeth, my sister stared at me for a long moment. Finally she relaxed her jaw slightly, pulled out my saliva-drenched balls with a wet slurp, wiped her mouth with the back of her hand, and said coldly.
“...You just shouldn’t have given it to another woman in the first place, you idiot.”
“I-I’ll try my best not to…”
Tears of relief streamed down my face at having barely saved my balls.
My sister glanced at me, then suddenly unbuttoned her pajama top to reveal her cleavage and said coldly.
“I just showered, so hurry up and cum on me now. That way your semen scent will stay on me while I sleep.”
“U-ugh… Understood…”
While my sister watched me with her pretty face, I pressed my cock against her pure white skin and stroked it frantically until I finally erupted.
“Huk…! A-ahh…! Kuu… Ohh… Ahh…”
Cum splattered everywhere, spraying all over her pajamas and bare skin. The thought of my thick semen scent wafting from her freshly washed, fluffy body all night filled me with an overwhelming sense of depravity.
But just when I thought it was over, my sister didn’t even blink. She swept her hair forward and said flatly.
“...Spray some on my hair too.”
“Kuk… O-okay…”
After being drained so much all day I was nearly at my limit, but I mustered every ounce of strength left to shake my cock and cover her pale hair in cum.
Only then did my sister slowly stand. This time she pulled her panties down slightly below her crotch and said.
“...Here too.”
“A-ahh…”
With her pussy just a few centimeters away, I rubbed my cock against her already darkly stained panties and wrung out the last of my cum.
My sister watched with satisfaction as the white semen pooled inside her gray panties like a small lake. Then she pulled them back up and said.
“Good boy. Now spray some on my blanket and pillow too.”
“O-okay…”
Using the last of my strength, I kept pumping out cum, completely soiling her pink bedding with my yellowish semen.
My sister looked at the now-damp blanket and pillow with a pleased grin, but then her expression suddenly froze again. She glared at me and said.
“...That girl you walked to our door earlier.”
“Huh…? Y-yeah…”
“What’s her name? What’s her Instagram ID?”
“H-her name is Hyuna… I don’t know her ID…”
When I answered honestly, my sister shot me a dissatisfied look, then shrugged.
“Whatever. Knowing the name is enough. She’s pretty, so she probably has tons of followers. Should be easy to find. That bitch…”
My sister crossed her arms resentfully and muttered, then suddenly whipped around and yelled.
“What are you standing there for? Get lost. I have class tomorrow so I’m going to bed early.”
“Y-yes…!”
I dashed to my room without looking back.
When I lay down on the bed and checked the clock, it was already approaching midnight. Chasing after Hyuna on her skateboard all day had left me physically exhausted, and having my cum drained repeatedly on top of that made me feel like death.
Too tired to even think about washing my cum-covered cock, I passed out on the spot.
“Zzz… zzz…”
I was deep in sleep when, in the early morning, the phone in my hand vibrated. I woke up blearily and checked it in a daze.
It was three in the morning. Never in my life had I received a message at this hour.
What the…? Who could be contacting me now…
I squinted at the screen and checked the message. Surprisingly, it was from Hyuna. She had sent a photo she secretly took while I was practicing on the skateboard.
I had no idea what to reply in this situation.
At the same time, simply reading it without responding didn’t seem very smart.
After agonizing over it for a while, I finally sent a short reply.
Hyuna read my message almost immediately but didn’t send anything else afterward.
With a confused mind, I fell back asleep until morning, when the next common sense alteration would begin.
