Experiment (1)

"Ugh, it's so damn hot I could die. What kind of backwater hellhole is this with not even a whisper of breeze?"

My older sister, Jeong Seo-yoon, grumbled irritably as she plopped right in front of the fan. Her thin white cotton t-shirt was ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠soaked with sweat, clinging transparently ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to her pale skin, and there wasn't a trace of a bra underneath. Her stiff pink nipples poked brazenly through the fabric, on full display. Apparently the fan wasn't cutting it; unable to bear the heat, she grabbed the hem of her shirt with both hands and yanked it up, fanning air straight into her chest. The moment the shirt lifted, the undersides of her breasts were laid bare—sweat beading on her white skin, and below that, her vivid crimson areolas.

Mom was no different. Drenched in sweat, she'd unbuttoned her short-sleeved blouse all the way down to her stomach and was fanning herself by hand. My younger sister, Jeong Da-yeon, had sprawled out starfish-style on the sofa, taking it even further. Wearing nothing but a sleeveless tank top, she'd spread her legs wide and hooked them over the sofa back. Through the loose dolphin shorts, the faint outline of her pussy peeked alongside her flushed skin.

I forgot how to breathe, frozen in place. For humans implanted with censorship chips from birth, the axiom "Others can't see my body" was absolute truth. That's why they were utterly defenseless. They knew breasts and pussies were embarrassing parts, but since no one could see them anyway, what did it matter? That livestock-level common sense was hardwired into their brains. They had no clue I was staring at their nipple colors and the sweat trickling into their cleavage like I was licking it up with my bloodshot eyes.

Hot blood surged to my lower half like a beast. Even though I'd only read about it in books, I instinctively knew this was lust—and an erection.

"Hey, Jeong Siwoo."

Sis, still fanning inside her shirt, jerked her chin at me.

I hastily shifted my gaze to her, mumbling in a daze. "Y-yeah?"

"What are you doing standing there like a spaced-out idiot? It's hot as balls—go to the mart and grab some ice cream."

Normally, I'd have flipped out about how I was always the one suffering and told her to fuck off. But not now.

"Uh, y-yeah... got it."

Right now, calming my throbbing head and dick took priority. Above all, I needed to get away from those ripe... no, those tits.

My patience was already teetering on the edge.

Sis clicked her tongue at my compliance. "Whoa, what's with you? Heatstroke? While you're at it, make sure mine has chocolate."

Mom and Da-yeon's orders followed.

"Siwoo, just get Mom a bag of ice?"

"Oppa! Canned coffee for me—the coldest one!"

I bolted out the front door like I was fleeing, their demands ringing in my ears. One more minute in that living room, and I would've lost control of my lust and done something stupid.

Stepping into the yard, the scorching heat pressed down, but I didn't feel it. I didn't have the bandwidth to care. Every time my fingers brushed the device in my pocket, shivers raced down my spine. My mind flashed to my family's exposed bodies—and even lewder scenes beyond that.

Still...

...They're family.

Thinking like this about my own family...

I'll fuck them all soon enough. How could I leave bodies like that alone?

Before long, I reached the rickety "Neighborhood Supermarket" at the village edge. In this rural spot, unless you drove ten minutes into town, this rundown place was your only option.

Drenched in sweat, I caught my breath and shoved open the creaky sliding door.

Ching-

Stale, musty air hit me as I stepped inside.

"Welc...ome."

A languid voice drifted from the back, where a flyswatter lay abandoned on a wide wooden platform. The woman who'd been lounging watching TV slowly propped herself up and turned to me. Her droopy eyes and lazy tone made her seem endlessly relaxed.

But it was her dangerous outfit that hijacked my gaze: ripped short denim hotpants and a thin, baggy white tank top that left nothing to the imagination.

"New face, huh? Oh, you from that persimmon tree house that just moved in?"

"...Yeah."

"Ahh. Sturdy young guy, nice."

Her half-assed compliment came with a disinterested once-over before she turned back to the TV.

"Don't just shop in town—buy from here often, 'kay?"

With that lazy reply, the supermarket owner, Lee Ju-hee, leaned back against the platform at an angle. The motion made the loose neckline of her tank top gape open. Thin straps slid precariously along her white collarbone, exposing the deep, natural valley of her cleavage—no bra to constrain it. Her coin-sized nipples ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠protruded blatantly through the fabric, swelling and flattening with each gust from the fan.

She was the same. Utterly defenseless, her brain deleting the very possibility that someone could see her cleavage or protruding nipples.

Not satisfied with the fan, she fanned herself lightly with a paper fan, flashing her smooth underarms each time...

I swallowed hard.

Ice cream, coffee, ice—who gave a shit anymore?

My eyes locked on her gaping neckline as I pulled the device from my pocket. The cool metal surface. I lightly pressed the power switch.

Whirr-

The familiar interface lit up. With trembling fingers, I tapped [Nearby Device Search].

I tapped it immediately. Only one device detected, as expected.

Five settings, but four were grayed out like they wouldn't open. I checked the only available one.

Beep-

The screen switched.

After a brief hesitation, I selected Olfaction. No big reason—just curiosity. How effective was this chip? Would she accept my sweat-soaked state now?

New sub-items appeared: sliders for values like affinity to administrator's scent, addictiveness, sensitivity—all locked at 0%.

Of ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠course. The Eden chip twisted natural pheromones and alluring body odors into "stink" or "bland air," neutering attraction at the source.

I cranked them all up to 50%.

Wanted to max it to 100%, but the slider threw a warning past 50%. No sense ignoring it and risking trouble, so 50% it was. Finally, I hit [Apply].

Ju-hee's body twitched for a split second, but she just yawned and kept fanning, none the wiser. I pocketed the device casually and turned to the old ice cream freezer, back to the platform.

Scrrch-

I slid open the frosted glass door. The blast of cold air cooled my forehead sweat, but every nerve was wired to the platform behind me.

Meanwhile, Ju-hee, lounging diagonally on the platform, shivered as a weird chill crawled up her spine.

"Hmm?"

Clueless, she wrinkled her nose. An unfamiliar, heavy, brain-melting dizzying scent slammed into her nostrils.

"Sniff... sniff sniff."

She inhaled deeply without thinking, flaring her nostrils. Afraid the smell might vanish, she stopped fanning entirely.

A thick musk like tanned leather. Each whiff of that hot, dense male tang sparked electric jolts deep in her gut—untouched for her 30 years.

She unconsciously turned her head side to side, seeking the source. And at the end of the trail...

"Ah?"

Her gaze naturally locked on Siwoo's back. He was bent over rummaging in the freezer. Each movement sent waves of heat—and that scent—crashing from gaps in his sweat-soaked t-shirt.

Ju-hee closed her eyes and breathed deep.

"Sluuuurp... haah... haaah... ♥"

Her eyes fluttered open, glazed and hazy.

What is this smell... it's too good.

Hot, ragged breaths escaped her lips. Sweat trickling down his nape, every wrinkle in his clinging shirt—it all hit her raw and vivid. Saliva pooled sticky in her mouth.

She wanted to get closer, bury her nose in that broad back, inhale until her lungs burst. Rub against that skin, fill her mouth with his sweat drops and breathe...

What's... what's this crazy thought...! Haaahhh ♥

Just imagining it sent jolts of pleasure down her spine. Confusion swirled at this first taste of ecstasy, but her desire writhed stronger.

Her Eden-tampered body had long slipped her control. Dopamine exploded with every inhale. Her back arched bow-like from the thrill. Her nipples hardened under the thin tank, straining to pierce the fabric.

Desperate to suppress it, she twisted and clamped her thighs under the short hotpants. But the friction only gushed hot, sticky juices, soaking her thin panties sloppily.

Squelch- squelch-

Never once aroused in her life, Ju-hee didn't even register she was in heat. She just sank deeper into the intoxicating scent.

She sat up fully, turning completely toward Siwoo, perching precariously on the platform edge, sniffing nonstop at his back.

Right then, Siwoo shut the freezer and stood with a few ice creams, ice bag, and canned coffee. He turned and approached the platform.

With each step, Ju-hee's shoulders jerked visibly. As the distance closed and the scent thickened, her reactions sharpened. Her pale cheeks flushed crimson, lazy eyes welled with moisture and lost focus. Unable to contain the heat, her red lips parted, a thin thread of drool dangling like a spiderweb.

Siwoo set the items down with a thunk on the counter right beside the platform. At arm's length, his thick scent engulfed her.

"Haaahh ♥"

Ju-hee let out an aroused moan despite herself, biting her lower lip. Her glazed eyes looked up at him pleadingly.

"Um, hey. You..."

Her swallow was audible. After agonizing hesitation, she forced an awkward smile.

"You smell really nice... do you use some kinda cologne or something...?"
