Strange Convenience Store (2)
...Swish—
"I-I'm stripped..."
I obediently pulled down my pants and underwear as the clerk instructed. For a 23-year-old lifelong virgin, this was the first time exposing my private parts in front of a woman. The cool air of the convenience store's backroom hit my lower half, sending chills racing across my skin.
That's when the clerk's indifferent voice rang out.
"Sir, you're not erect yet."
"Ah, well... it's my first time, so I'm a bit nervous..."
"For Semen Pay, you need to get erect first. Shall I help you?"
Swish—
With that, the clerk approached me. Her already pretty face drew closer, bringing a faint whiff of shampoo and cosmetics. I nodded without thinking.
"P-Please help!"
This definitely isn't a hidden camera prank. Watching her actions solidified my suspicion that this world's common sense was utterly twisted. If that was the case, from this moment on, I might as well stop holding back and just enjoy it.
"Alright then..."
Slipping—
The clerk slowly peeled off her top. Maybe because of the heat, her sweat-glistened skin came into view, but she didn't seem to care as she reached back and unhooked her bra. Her pretty, teardrop-shaped breasts bounced free, slick with sweat and gleaming in a way that looked insanely erotic.
Throb—!!
"Good thing it reacted right away."
The clerk smiled brightly, pleased to see my dick springing to attention in an instant. She tossed her bra aside carelessly and cupped her breasts with both hands, lifting them up.
"Then let's start your Semen Pay."
"So, how does this work exactly?"
"I'll handle it, so just relax and bust a nut."
Mwah—♡
"Guh!?"
...She kissed my dick!
I flinched in shock.
"Ah, uh...?"
My brain froze for a second. The warm, soft press of her lips on my glans, followed by that wet smooch as they pulled away—it was a sensation so novel that my spine went rigid.
But the clerk casually licked her lips and looked up at me.
"Where do you want to cum?"
"D-Do I pick?"
"Yes, sir. You choose everything. Feet, armpits—any body part is fine. Anal or creampie works too."
I didn't hesitate.
"B-Boobs."
...They'd been catching my eye nonstop. Honestly, no guy could resist those huge, perfect tits.
The moment I answered, the clerk nodded and pressed her upper body right up against me. She sank slightly to her knees on the floor. Amid the intoxicating mix of shampoo and her natural scent tickling my nose, she squeezed her pale breasts tightly together and slid my dick between them.
My cock slipped into the firm yet overwhelming cleavage of those gorgeous tits, her sweat-beaded skin starting to rub along the shaft.
Th-This is a paizuri...?
That's when the clerk muttered to herself.
"Whoa, your dick is huge..."
"W-What?"
"Oh, sorry, sir. I slipped... It was just a mumble—ignore it."
She apologized with a straight face and squeezed her breasts even harder. As my dick slid through her cleavage, slick with her sweat, the hot, plush flesh stimulated my glans like it was about to burst.
"Don't hold back—cover my tits with a thick load."
With that, she shook her breasts faster, ramping up the paizuri speed. The slick, squelching friction filled the room, and I felt my climax building fast.
"I-I'm cumming...! Urgh...!!"
Splurt! Gush, gush—!
The orgasm exploded, thick ropes of hot white cum blasting onto her breasts. Some even splattered her face.
"Hoo...♡"
But the clerk took it all without a hint of disgust. She even scooped up a trickle running down with her finger and gave it a little taste on her tongue.
I pulled my pants back up and asked,
"U-Um, you okay?"
"Ah, yes. Payment complete."
"...There's some on your cheek and lips too."
When I pointed it out cautiously, she wiped the cum from her cheek and lips with her finger, popped it in her mouth, and sucked it clean. Then she flashed a casual smile.
"Would be a shame to waste it."
...Is that how it works?
Anyway, once I finished cumming, she confirmed the payment and bagged my beer. Still reeling from the afterglow, I headed for the exit when the clerk suddenly called out from behind.
"Um, sir!"
"Yeah?"
"Could I maybe get your number...? Ah, never mind."
She started to ask something but bit her lip and stopped. Gone was her initial indifference—now she looked shy, making my heart skip oddly. But I grabbed the bag and left the store.
Ding-a-ling—
"What the fuck..."
What the hell just happened?
Belated shock hit me. Everything in that store felt like a dream, but the weight of the beer in my hand proved it was real.
A world that suddenly turned this lewd... If this twisted common sense was happening in schools, offices, even on the streets, it sent shivers down my spine—and made my dick hard.
"...Guess I'll head home."
Dazed, I stepped out toward the subway station. At least my place was right by the station— just a short walk to the apartment where I lived with my family.
But even on the way home, insane sights kept catching my eye. Next to the old smoking booth stood a new "Handjob Booth" where women were jerking off guys. And at the cafe nearby, they were selling Americanos with semen-flavored syrup.
Hard to believe even seeing it. The crazy part? College girls holding those cum-syrup coffees, slurping them down like they were delicious.
Seeing that made my stomach churn. As a cafe part-timer, it was the last thing I wanted to witness.
Never going to that cafe again.
I vowed it to myself and hurried home.
...
By the time I got home, it was already 8 PM. I sighed and set down the convenience store bag. My stepsister, lounging on the sofa scrolling her smartphone, glanced up at the sound.
"What'd you buy at the store?"
"Uh, some beer."
"You get mine too?"
I flipped her the bird instead of answering. She scrunched her face.
"Ugh, dick... Eating alone again."
"Watch your mouth with your big bro."
"Pfft. You're not even my real brother."
She wiggled her toes, casually hitting where it hurt. I was speechless for a sec.

She was right—we weren't blood-related. Our parents remarried when we were kids, 6 and 3 years old, and we'd lived under one roof for 17 years since. Basically siblings in every way that mattered.
Of course, in Korea, even blood siblings don't always get along—sharing the same air can grate sometimes. We'd fought plenty.
"You're still too young for booze."
"What bullshit. I'm an adult now."
She grumbled. For some reason, seeing her like that eased my mind. Same rude mouth, same bitchy nagging—but after the bizarre shit earlier, this childish bickering felt reassuringly normal.
Hiss—
"Ah, hits the spot~"
I plopped on the sofa and took a swig of beer. Chae Na-hee glanced at me.
"Oppa, just one sip."
"Nah. Go buy your own."
"C'mon, don't be stingy—share."
"Why should I?"
I was mid-sip when she said it dead serious.
"I'll suck your dick instead."
"Pffft!!!"
Beer sprayed into the air. She squinted.
"Ugh, jerk. It splashed."
She wiped the beer off her thigh, grumbling, but I was reeling from her words.
I dabbed my mouth with my sleeve and asked,
"W-What did you just say?"
"I'll suck your dick, so gimme some beer."
Chae Na-hee's face was straight. Mine twisted up.
She's serious?
Her insane offer. But she didn't seem fazed at all—like it was perfectly normal.
One sip for a blowjob? Something terrifying was going down.
No way I'd agree.
It made zero sense by my logic, but she was wiggling her feet on the sofa, waiting for an answer like hurry up.
"What? I said I'd suck it."
I had to refuse. She's my stepsister, for fuck's sake. Siblings don't do that.
But...
Why can't I stop staring...?
My eyes roamed her without thinking. Black straight hair to her shoulders. Her usual dolphin pants at home. Those long, pale thighs underneath.
I'd seen her a million times, but today her outfit and skin kept drawing my gaze. Disgusting to feel that spark of expectation toward my stepsister, but I couldn't deny the temptation of her offer.
Still...
"Hey, cut the nonsense. No."
Thank god I mustered the willpower to shut it down. Before she could retort, I snatched my beer and bolted to my room.
"God, you're so cheap."
Her grumbling followed, but right then, escape was my best bet.
