A Huge Mistake
A huge mistake . . . Squelch! Squelch! Squelch-!!
“Ngh, ohhh♡♡!?”
Was it because my pistoning suddenly sped up? Kwon Ra-hee's moans changed.
“Hngh, yeah… ohhh♡”
On all fours, Kwon Ra-hee had her eyes rolled back and her lips pursed in a perfect O. I'd jerked off imagining her plenty of times, but I'd never even dreamed of her making such a slutty face. She looked like pleasure had completely overtaken her.
“Ngh…!”
But I was feeling the same way—like my eyes might roll back from the ecstasy. I was barely holding back from cumming.
As I kept pounding away, desperately fighting off the urge to blow my load, she suddenly whipped her head around to look at me from her all-fours position.
“Harder, pound me harder……♡!”
Kwon Ra-hee stared at me with eyes gleaming with lust and shouted it out. I obliged, slamming my dick in even more vigorously.
Squelch! Squelch!
“Oooohhh♡♡! Ahh! Haaah♡♡!!”
Incredibly lewd moans. Her body was giving off such a sweet, intoxicating scent—like pheromones were pouring out of her—and her sticky pussy folds clung to my dick without a single gap.
How much time passed like that?
“I've hit thirty now!”
“Yeah. You can cum now…♡”
“C-Cum?”
I panicked at Kwon Ra-hee's words. And for good reason.
...She's got no-kon, right?
Plus, she had a boyfriend. But Kwon Ra-hee said it like it was the most obvious thing in the world.
“Yeah, obviously creampie me…♡ Hngh, ngh♡ I'll milk that cock with my pussy, so just relax and dump it all inside……♡!”
“Ugh, then I'm gonna cum?”
“Yeah! Cum! Fill my womb up completely!♡♡”
She stared right at me as she said it. Our eyes met, and Kwon Ra-hee rolled her eyes back, stuck out her tongue in full ahegao, and yelled,
“Creampie this slutty pussy, please♡♡!!”
The moment I heard Kwon Ra-hee begging in that vulgar tone to cum inside her, an unbearable wave of pleasure shot up my spine and exploded.
“Fuck!! Here it comes!!”
Spurt spurt spuuurt-!!!
“Ngh, oooohhh!!?♡♡♡”
As the hot semen started flooding her womb, Kwon Ra-hee let out a humiliatingly slutty moan and threw her head back.
“I'm cumming. Cumming! I'm cuuummiiing♡♡♡!!”
Right in front of everyone at the gym, she rolled her eyes back, stuck out her tongue, and declared her orgasm. With her facial muscles slack in that ahegao expression, she took every drop of my cum into her pussy—and she looked utterly blissful doing it.
Thanks to that, I got to cum nice and hard too.
Spurt— glurk glurk……
“Hoo, haaa……”
After that ecstatic creampie sex, we collapsed onto the mat, drenched in sweat like we'd just finished an intense workout.
As we lay there basking in the afterglow for a bit… I felt Kwon Ra-hee's hand gently stroking my head.
“How was it? Feel like you got a good workout…?”
“Yeah. Thanks to you, sis…”
“Good…♡”
Her sweat-soaked face broke into a bright smile, and she looked stunning—enough to make my soul leave my body. I still couldn't believe I'd just fucked a woman this gorgeous.
“What now?”
“We're done, so let's rest a bit…? And clean up after.”
“R-Right.”
I hurriedly tried to pull on my pants and underwear, then realized my dick was a mess. And Kwon Ra-hee was eyeing it hungrily, licking her lips.
“Could you maybe clean my dick for me?”
At my request, she slinked over with a seductive smile like she'd been waiting for it.
“Slurp! Sluuuurp! Chuuuup—!!♡♡”
. . .
Shhhh—
“Haaah…… Feels good.”
In the gym shower, washing the sweat off my body felt like it melted away all my fatigue. I hadn't done any real exercise, but fucking Kwon Ra-hee made coming to the gym totally worth it.
And not just any girl—Kwon Ra-hee, with over 50,000 Instagram followers. Being able to fuck her like that had to be because this world's common sense had twisted, right?
Can my life really change this much overnight?
It was almost scary. Just a little while ago, I was a total virgin loser, and now I was doing all sorts of lewd shit… It felt great, but my head was still spinning.
And the changes from this twisted common sense weren't just that.
“Um, excuse me……”
“Yes?”
As I finished showering and stepped out of the locker room, someone was waiting for me. Glancing over, I saw a fit woman in workout clothes staring at me.
“Could I maybe get your number?”
“...My number?”
“Yeah. I'd love to do some sex training together sometimes… You seemed like you get rock-hard super easy earlier, and I come to the gym at this time every day.”
She said it while making an O-shape with her fingers, then shook it in front of her outstretched tongue, mimicking a blowjob.
“I suck dick really good too.”
“Here, phone.”
I ended up giving it to her like I was hypnotized. She flashed a naughty smile, saved my number, and headed back to workout.
But as soon as she left, other women started filling the spot.
“Oh, hey! Me too, your number!”
“Whoa, you smell so fuckable.”
“Hey, how many times a day can you cum?”
Suddenly swarmed by female gym members asking for my number or personal info.
“Uh, um……”
Their sweat and perfume made my head spin. Some even offered to let me fuck their pussies right then and there, but I politely turned them down, saying I was too tired today.
No, really, if I cum any more, I might actually die…
It wasn't a lie—I had no loads left. I was worried I'd catch a cold tomorrow or something.
“Then just your number!”
I finally escaped the gym after handing out my number to the women.
Just when I thought I was free, a demure-looking woman who'd followed me out blushed and spoke up.
“Um…… Got a sec?”
“Sure. What's up?”
“Well……”
She fidgeted shyly. She had a timid but kinda cute face, and soon she seemed to steel herself, looking me straight in the eye.
“S-Sorry, but… would you sell me the panties you're wearing right now?”
“My panties? Out of nowhere why?”
“T-To use as jerk-off aid at home……”
...A vulgar request that didn't match her shy, prim appearance. But in this world, it didn't shock me much.
“Jerk-off aid?”
“Yeah. If it's got cum on it, I'll pay double. Or you can just give it to me.”
“Uh, how much were you thinking?”
I didn't refuse outright. She held up two fingers.
“20,000 won?”
“No. 200,000 won.”
Way more generous than I expected. Selling my worn panties for 200,000 won…
That's 20 hours of part-time work.
Was it illegal? The world's common sense had gone lewd, and she was asking so boldly in front of the gym, so probably not.
“Should I take 'em off right here?”
“Y-Yes, please…♡♡”
She nodded with a somehow dangerous expression. I wondered if this was really okay, but the thought didn't last.
200,000 won for a pair of panties. Free money.
“Hold on. I'll go to the bathroom and—”
“N-No! Take them off in front of me! That way I know they're fresh off you…… And I can feel the warmth……”
“Oh, right……”
What a specific demand. I nodded in a daze.
“Sure. One sec.”
In a world where women walked around subway stations with their tits out, stripping off panties in public didn't seem like a big deal, so I just yanked my pants down openly.
“Whoa, wow……♡”
She gasped in awe at my dick. Kinda embarrassing.
“This good?”
“Y-Yeah……”
Shff—
“Here.”
I handed over the freshly removed panties, and her shy demeanor flipped in an instant.
“Ah, aaah……!♡ Thank you……!”
She cradled them reverently like a treasure, then buried her nose in them, ignoring all the stares around us.
“Sniff, haaa……! Hnff…♡♡”
Eyes rolling back as she sniffed my panties. What do you even call this…… She looked so prim and proper, but the ecstatic face she made sniffing away was kinda bewildering.
“Sniff, fuu♡ Haaa♡”
“Um, excuse me?”
“Ah, here. Thank you……”
Thankfully, she snapped out of it quick and handed me 200,000 won in cash.
Imagining her going home to use my panties as jerk-off aid made my dick twitch a bit, but if she noticed, she'd probably drain me dry again, so I snatched the money and hurried home.
Clomp clomp—
“Jackpot. 200,000 won for some panties.”
If I kept selling panties like this, I'd make more than a big corp salary, right? But as I headed home thinking that, reality hit me fast.
. . .
Bang-!!
“Oppa. What the hell?”
“Aish. Knock first.”
I was in the middle of gaming when she barged in! Glancing over, there was my stepsister, arms crossed, staring at me with a blank expression—no knock, of course.
Something felt off from her usual vibe. I noticed her colder-than-usual face and let go of the mouse.
“What. What's up.”
“The clothes you left after the gym. You put 'em in the laundry basket, right?”
“Yeah. Why?”
“Your panties aren't in the laundry.”
I answered Chae Na-hee's question casually.
“Panties? Sold 'em to some girl on the way home.”
I figured it wasn't weird in this world's common sense, so I was honest. But her reaction was way off from what I expected.
“What? You sold your panties?”
Chae Na-hee's face turned serious, like she'd heard something insane, glaring coldly at me…… Her sudden chill made me sense something wrong too.
What the?
Did I fuck up somehow? A bit puzzled, I asked,
“Uh, she paid 200,000 won. Problem?”
“You sold that? To some other girl?”
“Uh… Was that bad?”
My voice lost some confidence, and Chae Na-hee furrowed her brows.
“I was gonna use it as jerk-off aid, and you just sell it? How could you not think of your stepsister you live with? What am I supposed to jerk off to without your panties?”
“Wha—huh? What do you—”
“Fucking annoying.”
Slam-!!
She slammed the door on her way out. Staring at her pissed-off back, I muttered blankly,
“What……?”
