Tutorial Kiss with My Tomboy Childhood Friend
Jo Na-young. My childhood friend we'd grown up with since we were kids. We went to school together until middle school, then drifted apart in high school, only to reunite in Seoul after college.
"I figured you'd be on TV by now, not all beat up and shit. Watch yourself next time."
"You crazy bitch. Is that any way to talk?"
It had been years since we'd last seen each other, but she'd turned into a proper, mature woman with curves in all the right places. Back when we were running around the neighborhood together, she was a total tomboy.
"Never thought you'd end up managing celebs. They all hot?"
"Yeah. One of 'em's prettier than you."
"You asshole. Can't even say anything nice to save your life."
We'd meet up now and then, knocking back drinks and trading insults. She had a filthy mouth even back home, and this chick hadn't changed a bit.
"I go down to see Grandpa pretty often. Looked like his leg was bothering him last week."
He hadn't mentioned anything about his leg hurting on the phone, so it was good to hear it this way. Turns out later she'd gotten groped by her boss at the ad agency she'd busted her ass to get into and quit on the spot. Now she freelanced, heading home more than I did.
"Decent gig and you blow it? Tone down that temper. What the hell did he even do?"
"That fucking prick groped my thigh at the company dinner. I smashed a beer bottle over his head, and I got fucked over for it. Piece of shit."
"Yeah? Good for you. Classic Na-young. Nice one."
Heard later the guy got caught messing with other female employees and got canned. The company offered her reinstatement, but she turned it down.
"Freelancing's not bad, so I started a YouTube channel. Pays pretty well."
"What? You're a YouTuber too?"
"Kekeke, call this body an influencer from now on."
She said it as a hobby, but when I checked the channel she told me about, it had over 100k subscribers.
Damn, over 100k watch this shit?
She wandered around town introducing spots and chatting—turns out from the comments, it was all because of her looks.
"You're just selling your looks."
"You psycho fuck, you think I'm hawking fish? In this day and age, looks are power."
She struck a pose and flashed a flirty eye smile. It suited her tipsy, disheveled vibe perfectly. Lately, I'd been seeing her more as a woman, but she didn't seem to see me that way.
Just a comfy childhood friend, that's all.
I knocked back the soju in my glass with that thought. Tasted extra bitter that day.
I opened KakaoTalk and messaged Na-young.
— You good now?
— Nah, still home. Heading up tomorrow
Kissing a total stranger? Nah, she's way better. I've been seeing her as a girl lately, but is it just 'cause I'm comparing her to the tomboy she used to be, or am I actually getting turned on by her? Not sure.
A kiss'll tell.
I pulled the soju and beer I'd bought out of the fridge to drink alone. As I set up a makeshift drinking spot in the living room, Na-young's voice rang out from the entrance.
"Kuhahaha, this body's here!"
Her tomboy entrance antics were still the same. I chuckled and turned, but suddenly time froze.

Prize and penalty both doubled. But I was ready this time—works in my favor.
Common sense updated.
Changed from stranger to homeowner. Makes sense since Na-young's no stranger.
"Can't touch her tits?"
Na-young's rack looked extra tempting as she stood there frozen. Guess I am seeing her as a woman.
Plenty of chances, so hold off for the tutorial.
My mouth watered, dick throbbing, but she said plenty of chances, so I held back.
Quest starts in 5 seconds. 5…4…3…2…1….
The message vanished, and time resumed.
* She sets the snacks on the table and gazes at me intently.
"Why you staring like that?"
"You're still out of it. Not even gonna kiss me hello."
"Oh."
Words Na-young would never say normally. Altered common sense in effect.
"Forget it. What kinda headspace you in right now? Big sis'll handle it."
She steps close, rising on her tiptoes. She's pushing 170cm, but still over 10cm shorter than me. Her cheeks flush as our lips meet.
This time, I didn't dodge.
*Churp… smack, slurrrp… mmmwah.*
Sensation and scent hit at once. A sweet, floral aroma taps my lips, spreading a lickable sweetness inside. My lips part instinctively, and that's when her tongue slips in.
Viscous slickness and sensual wriggling numb my mouth. Like lotion gliding between gums, ravaging the insides.
*Slurrrp… gulp… mmmwah… haa♡*
How long did she suck and lick? Superhuman willpower kept me from grabbing her waist. Losing a million won means sucking fingers the rest of the month!
Lip and tongue smacks, swallows—they're obscene BGM tickling my ears. No wonder they call it ear-fucking tits. Sound alone getting me this hard.
Na-young's excited too, rubbing her chest against me mid-kiss. Her loose top slips down, barely covering her nips—my dick's about to burst. Grabbing those half-exposed tits would be heaven, but quest rules… tears—no, pre-cum held back.
Our ragged breaths slow. Her tongue retreats, trailing sticky saliva.
Who knew my childhood friend's spit could be this sweet.

"Haa, haa…."
Lips part, a thin saliva thread stretching between us before snapping. No clue what my face looked like, but Na-young's was beet red, on the verge of exploding.
"Just a kiss and you're this hot? Haha."
She laughs it off and sits. Common sense alteration means she thinks it's just a greeting, but her body's not fooled. That heated tongue swap lingers in her flesh. No way she'd be this fidgety over a simple hello.
Congrats! Cleared Tutorial Quest. 2,000,000 won prize deposited—spend wisely.
Quest clear and the two mil didn't even register. Sleek brown hair, sharp jawline, cat-like alluring eyes, killer curves—especially that standout chest. Art in motion. Couldn't peel my eyes off my childhood friend's fresh, vibrant body as she arranged glasses and snacks in front of me.
"What're you staring at? Am I that pretty?"
"Yeah."
The glass she was setting down freezes mid-air. Her already pretty eyes go wide.
"What's with you? Usually it's 'fuck off' or whatever. Say shit you don't mean and you'll die young."
"Curse me out then. Even compliments get you bitching."
"Fine, love it. Fuck… kekeke."
The awkward vibe melted away. This is good for now. Like Yemina-i said, chances galore.
"Tired? Barely drank and you're red as hell."
"Talk to your own face. About to burst—ease up on the mixes."
"What? We haven't even started."
I clinked glasses thinking of Na-young moaning under me someday. Started off weird, but Grandpa's wish? Loving it.
"Ugh, my head."
Woke up sprawled in the living room. Chugged thinking of Grandpa at the end—blacked out first. Na-young's gone. Said she'd head out early, probably en route to Seoul.
Touch my lips—no Na-young sensation. Kiss that intense, but booze sterilized it.
Wasted.
Told you there'd be plenty of chances.
"When? Gimme quests whenever I ask?"
If you can handle it. Quit the company first.
"The company?"
Yeomra's power only works in the house. Grandpa picked a prime spot. Common sense alterations galore here.
Damn, Grandpa saw how many moves ahead… Wait, no. Quitting a job I loved?
"No other way? Like moving the power to my officetel."
Nope. World's got rules. This house is the perfect spot for alterations. Location's non-negotiable.
It was the job, sure, but I loved the people too. Except Han Yu-ra, that bitch.
