Arousal Side Effects and the Trouble Cookie
Side effects are arousal? Slurp, smooch... smack... The intensity of kneading her breasts changed how I teased her with my tongue. As I squeezed and twisted them like milking, her body waved in the same direction. I slipped my hand between her thighs, and she didn't know what to do. With me there, she couldn't grind like she would when masturbating alone, but it seemed she couldn't help letting her hand wander.
"Hngh... hngh, uh, uh."
Her breathing grew ragged, and Na-young pulled her tongue back first. Her flushed cheeks, ripe like a perfectly ripened peach, were so tempting I wanted to bite them. I slowly released her breasts, which felt like I'd kneaded them hundreds of times. I wanted to fondle them all night, but I held back, thinking tonight wouldn't be the only one.
She looked at me with hazy eyes, then her body shuddered. "Hahk! Wh-what do I do..."
"What's wrong?"
"N-nothing! I, bathroom. Follow me and you're dead!"
She vanished in an instant. I didn't even have time to retort that I had no reason to follow her to the bathroom.
A moment later, Na-young came out with a troubled expression. She was gripping the hem of her skirt and walking carefully, which looked suspicious, but I didn't ask why. Her face said she'd punch me if I did. For the record, this bitch's punches had been brutally sharp since we were kids.
"I'm going to the convenience store, so stay put. We're gonna keep drinking."
I had a pretty good idea why, but I didn't say it out loud. Of course, I didn't ask either.
"Got it."
I watched her waddling out, hand covering her ass as much as possible.
My name is Jo Na-young. I'm in the biggest crisis of my life right now. I just greeted Ji-hoon, and my lower belly trembled as something gushed out wildly.
This won't do. I rushed to the bathroom, and down there was soaked.
"Fuck, shit... I squirted!"
It was so much that my panties were drenched. More than when I masturbated at home.
I squirted just from seeing Ji-hoon's face?
I was speechless. Unless I'm some crazy slut, he hadn't done anything, yet I got this wet?
What do I do? No spare panties.
Of course there weren't any extras. No way this house had women's panties, and I couldn't keep drinking with Ji-hoon going commando.
Gotta buy some.
Thankfully, there was a convenience store nearby. Grab some disposable ones, and I'd escape this mess. I mumbled something to Ji-hoon and headed out, starting the car. It was walkable, but no way was I wandering around panty-less.
I needed to focus on driving, but this absurd situation wouldn't leave my head.
Am I insane? Squirting just from meeting him? Jo Na-young, snap out of it!
I said that, but picturing Ji-hoon's face heated me up again. My breathing roughened as I traced his broad shoulders down to his firm forearms.
Fuck, no.
I pulled over in a secluded spot. At this hour, hardly any cars passed. I opened the glove box and pulled out some disinfectant. Extra hygiene in the car.
You fucking bastard, this is your fault. Why do you turn me on so much?

The heroine's masturbating in the car.
I stared into space with a dumbfounded look. The girl who said she was going to the convenience store—what the hell was she doing in the car?
It's a common sense side effect. Nothing to worry about.
"Side effect? What's that?"
If she gets aroused in a place where common sense is altered, the afterglow lingers. It's fine if she leaves after it cools down, but not now. She got randomly horny outside without knowing why.
I'd known Na-young forever, but I had no idea about her sex drive. Still, she wasn't the type to masturbate on the street like that.
"She doesn't do this every time, right?"
She's pent up. If you relieve her, it won't happen. She'll obsess over you more, though.
Obsession with me was better than her masturbating anywhere. A healthy obsession even helped with sex.

Tutorial got me 2 million, so two kisses and one breast fondle netted 5 million total. Like Yemina-i said, just have sex here and I'd be making eight figures a year.
Check your status window to confirm the rest.
My available points jumped to 300, and Na-young's status had updated too.
Her breasts are really only half-unlocked.
"How do I unlock the other half?"
The thin fabric might as well not have been there—it felt perfect—but I wanted to pinch her nipples and suck them.
Another quest will pop soon, so hang in there. Half-unlocked means it won't take long.
Yemina-i said something nice for once. A fortune cookie-like treat appeared in the air—the quest clear reward item.
"This the Trouble Cookie?"
Yes. Grab it for the description.
I grabbed the Trouble Cookie, and a message appeared.
Trouble Cookie
A cookie that foretells the target's misfortune. Contains info to avoid the misfortune.
Info provided as text, voice, photo/drawing, or video.
Like a fortune cookie's slip of paper, something was inside. I cracked it open—a USB drive. High-tech compared to those paper scraps.
The laptop to check it was in the third-floor attic.
Hope I have time.
I stood, but heard the front door. I pocketed the USB first.
"Where you going?"
"Bathroom. Be right back—sit tight."
I'd check the contents later and headed to the bathroom, then back to my seat.
Nothing changed except common sense, but she was slyly avoiding my eyes. To hide why she'd gone to the store, she'd bought a ton of booze.
"Fridge is stocked—why buy more?"
"No beer I like. Remember that."
"It's somac—any beer works. You said so before."
"Don't be petty! Tastes change!"
She's snapping for no reason. Can't even remember her own words. I almost snapped back but shut my mouth at her expression. I could see the embarrassment of squirting in her panties, the lingering masturbation arousal, guilt over overreacting, and her fidgeting from failed face control.
Good job. Women don't like clingy guys. Quest affection has limits, so rack up points like this.
Yemina-i praised me for once. She'd been sassy retorts earlier.
I silently mixed two somacs and set one in front of Na-young.
"Drink this and chill. No idea what pissed you off."
She clinked glasses awkwardly and chugged. Her kah was quieter than usual, but the irritation vanished from her face. We traded a few rounds, and the buzz hit fast.
Na-young doesn't whine when drunk—she clings in weird ways.
"Kah~ Killer. Best somac from my ball-bro."
"Girl saying 'balls'? You don't even have 'em dangling."
"What's good about dangling cum-shooters outside? Ours stay inside. Right? Heh heh heh."
Her expressions get vulgar and extreme. Grinning sleazily like an old perv while clinging was par for the course.
"Ugh, cut it! Don't cling so gross!"
I liked it, but pushed her off on purpose. She wouldn't remember common sense-altered stuff, but drunk grinding would stick in her memory.
"Why, horny? Want me to jerk you off?"
"You crazy bitch, get properly drunk before talking shit. No filter."
I came on strong, pissed. Even as close friends, she wouldn't say that if she saw me as a man. It assumed safety.
She doesn't see me as a man.
Could be drunken nonsense, but there's truth in wine. She finally backed off and sprawled on the floor, panties from the store fully visible—total vulnerability.
"Hng, this fucker ignores my seduction."
Hard to tell where the sincerity ended. I almost asked, but she crossed her legs pointedly, killing the timing.
Guess I'm just another dumb male. Couldn't tear my eyes from her pale thighs—then snoring leaked from her nose.
Snooore, rrrumble... pffft~ With occasional guh grunts. She was out cold.
She was this gone, so I should've been wasted too, but I'd paced myself watching her. Curiosity about the USB kept me going.
I carried Na-young to a room and headed to the third-floor attic.
