Chapter 17
"Just crash here." "Remember that convenience store from earlier?" "The one before we entered the alley?" "Yeah. Grab some booze and snacks there. I'll tidy up the house while you're gone."
"Got it."
"Don't rush back—take your time picking stuff out. Actually, just go for a 10-minute walk. I'll text you the room number."
Does she have that much to clean up?
I watched Yoo Seol-ah slip through the building's front door on the first floor, then headed to the convenience store I'd spotted earlier. The door chimed as it slid open.
Isn't it past 11 p.m.? That's night shift territory. They usually staff guys for this hour, but there's a girl behind the counter.
A little surprised, I glanced at her—and our eyes met.
"Huh? No way, Sion?"
"...Jia sunbae?"
"Why 'sunbae' again? Call me noona."
"Sure, noona."
"You live around here?"
Technically, there's a closer convenience store near my place, but something told me I should play along.
"Yeah. First time at this one, though. You work here regularly?"
"Nah, just covering a shift. Not my usual gig—someone begged me. Don't tell anyone, okay?"
She pressed her index finger to her lips with a theatrical shh.
It's not illegal or anything. No big secret, right?
"Night shifts at a convenience store seem kinda risky, though."
"Worried about me?"
"Well, yeah..."
Yoo Seol-ah could handle rowdy customers or even an armed robber without breaking a sweat, but her sister was just a regular person.
Jia-sunbae—noona—frowned a bit and playfully nudged my shoulder. I'd always thought she had this effortless charm with everyone.
"If you didn't have that 'behind me' vibe, it'd be perfect. But don't worry—the station's right nearby. Never had issues even when I did this for real before."
"That's good to hear."
"Yeah. What're you buying? I'll hook you up cheap."
She sounded like a market auntie, so I just laughed it off and headed to the fridge for drinks and booze.
We'd already had plenty tonight, and from earlier, Yoo Seol-ah seemed to like sweet, low-proof stuff. I grabbed four fruit wines: peach, grape, and two more.
I set the bottles on the counter first, then scanned the 2+1 drink deal for something safe. Two for us, one for noona.
She was a good sunbae anyway, but more importantly, Yoo Seol-ah's sister meant we got along automatically.
For snacks, I was eyeing some chips when another aisle caught my eye. Sleek packaging screaming 0.01 to 0.03, ultrathin.
...Should I grab condoms?
Sure, I'd survived years as a hardcore otaku and my isekai stint, but inviting a girl over for drinks at night? Classic romance anime cliché. Hard not to think about it.
But rationally, on Earth terms, we weren't anything yet. Lee Seo-yeon had cranked up the flirt level earlier, but that was her leading the charge.
"Wanna grab a drink?" doesn't have to mean that. And the cashier was her sister, which complicated things more.
'Seol-ah's got a boyfriend lately...'
'If he's a creep, I'll take him out...'
Classic siscon vibes from Jia-noona.
Earth-wise, today was our first real meeting. Buying condoms on day one? Kinda screams "bad guy."
And if Seol-ah just wanted casual drinks, spotting them would lead to one of two reactions:
"...You came here planning this? ...You're disgusting."
Or her gleefully teasing me into submission. Given our rivalry, option two seemed more likely. Honestly, neither sounded terrible...
"Chips got you that stumped? Want recommendations?"
"Yeah, pick a few for me."
Her voice came from right beside me. I'd been lost in thought by the snacks; must've looked like I was agonizing over flavors.
Sisters might share tastes. I wasn't big on chips anyway—better than my picks.
As she grabbed a few and headed to the counter, I made a snap decision.
No way she'd know I was heading to Seol-ah's. Condoms didn't mean using them tonight, and noona seemed chill enough to play it off or tease.
Boldly, I snagged the 0.01 pack and dropped it on the counter.
The booze was already bagged; she scanned the chips. After ringing up the three packs, it was condom time.
She scanned the small box casually, then spoke.
"That's twenty-one thousand... f-four hundred won."
Sudden formal speech? I swiped my card; it went through quick.
"Here, one for you."
"Thanks."
Back to casual, but she avoided my eyes. Aren't social butterflies immune to this stuff?
No more to say, I bolted.
I'd dithered long enough—no need for that walk. I pulled the condoms from the bag, tore open the box, and split them between wallet and pocket.
Phone check: two messages.
...Too lazy to buzz me in?
Fair enough—I'd vouch for party members without thinking twice. We'd trusted each other with our lives.
Room code was no biggie. Punched it into the lobby panel; door clicked open.
Clean exterior, fancy elevator. Green floor lights lit up underfoot, auto-pressing floor 1.
My place didn't have this. Perks of being a popular illustrator?
Seventh floor—701 straight ahead to the left. Hand near the lock lit it up. Slowly keyed #112982*; electronic beep, then I turned the handle.
First time entering a girl's place without it being a little sister.
Yoo Seol-ah greeted me right at the entryway.
"You got a haul. How much? I'll Venmo half."
"You're providing the spot, so it's on me."
"...Whatever, come in."
No shower or change—still in the black knit dress. Past the short hall, killer living room view. Extra bedroom too.
"This place is nice. Two rooms?"
"Mini two-room. Or 1.5-room."
Knowing Baek Sia's mess, I hadn't expected spotless—but it was pristine. Wood furniture, beige tones, upscale hotel vibes.
"Hand it over."
She took the bag from me, then froze. Awkward silence stretched.
"...Smells like cologne or something."
Chill down my spine. I never wear cologne. Today: club trio, then Jia-noona at the store. Only she had scent—and we'd barely talked.
But Seol-ah's senses weren't normal. Quick to clear it up before misunderstandings.
"Ran into your sister at the store up front. Chatted quick. She's covering a shift."
Seol-ah looked flustered.
"...You didn't say you were meeting me, right?"
"Nah. Just grabbed her a drink."
"Phew... Dodged a bullet. Sit."
She set the bag by the round table, plunked four cans down, and sat. I took the opposite chair, sliding over one of the three drinks she skipped.
"Your sister's not crashing here too, is she?"
"804—studio up one floor. Kept bugging to move in together... Told her no way I'd cover her rent for a mini two-room."
Right above us? What if she just—
Seol-ah read my mind.
"Told her to text first if visiting. Doesn't know the code anyway."
Just us, then...
"Whoa... gear is top-tier."
"Fan page cash went hard here and on work setup. Wanna draw something?"
Drinking and chatting blew past expectations—way more fun.
"How're you this good?"
"Drew stuff as a kid copying refs... Whatever."
"Year of practice and you'd sell. No cap."
Tried her setup. Checked her cosplay stash.
"All handmade?"
"Some bought, older ones DIY. Recent complex ones? Magic skipped sewing."
"Even old ones are pro."
"Wanna try a maid outfit?"
"...Height gap's 20cm. It'd rip."
"Don't say height. Say build difference. Fix it."
Her closet corner was cosplay heaven. Time flew—past 3 a.m. with otaku talk. Forgot the condoms entirely.
Time deletion was made for this.
"Time flew..."
"Yeah, you said you're solo-living?"
"Since late January."
"Just crash. It's past 3."
"...Huh?"
"Slept together all the time over there."
Her words startled me, but yeah—Astasia campouts with her alarm spells. Sofa kept distance anyway.
"Spare toothbrush in bathroom drawer. No change of clothes... Check the bath."
Slipped on slippers; she extended a hand, mana surging. Battle-level buildup.
"Trust me?"
"On magic? Yeah."
"----------."
"----------."
⟨ Purification ⟩
A cool wave washed over me; she smirked, a bit annoyed.
"Done. Cleaner than water."
Clothes, body—crisp and fresh. Insane mana control.
"Brushing first. Getting sleepy."
"Host's call."
Her turn done, she emerged as I finished. Bedroom lights off, mood lighting on, her in bed.
I headed for the sofa—
"Why sofa? Bed's huge. Plenty of room."
Composure cracking. Astasia side-sleeping was different from same bed.
She lounged against the headboard, scrolling casually. No self-study studio vibes ever turned horny, so maybe she just wanted playtime.
Refusing might weird her out. Into the bedroom.
Hotel-king size. No lie—room for two. I took the far side. Floor-to-ceiling windows promised city lights.
She set her phone up top, turned away sideways.
"Blanket's all yours. I sleep fine without."
Same here—Astasia fixed my blanket dependency.
Quiet fell; my heartbeat thundered. Assassin mind control? Useless.
Deep breaths to steady—her breathing shifted. Out like a light.
Staring at her back, eyes drifted despite myself to her hips. Slim waist amplified the dramatic curve. Knit dress barely skimmed her ass; plush thighs below.
"Mm..."
She tossed hard—bad sleep habits? I held my breath. Dress hiked up, exposing hidden territory.
Short even at dinner, but shorts then. Now... just panties?
Curling up yanked it higher. Plain gray, thin, no trim but letters up top—clinging tight. Simple design spotlighted her impossible sexiness despite petite frame.
Panty flashes in manga only. Blood rushed south; iron will barely held.
Emergency measure: off the bed. Jerking to a sleeping girl's panties? Manga trash. Rape-adjacent. Jailbait.
Unprecedented arousal, throbbing bigger than usual—above average baseline.
Seol-ah was surely inexperienced. Her small build + my size = rational caution essential.
"Haa..."
She rolled facing me. Face beyond "pretty"—drool-worthy. Ample breasts, waterdrop perfect. Smooth belly peek.
But killer: those plump mounds straining the gray fabric, fine smooth line between.
Brain blanked. This vulnerability tested limits.
Even innocent, your fault too. Those gripped labia—virgin tight—splitting with my thickest part, delving deep... bliss.
Shedding first pussy, I'd blow before halfway—but slicking up, perfect. Endless orgasm, scraping walls till hilt-deep, tip kissing cervix.
Back on bed, hands on waistband before her sleeping face. Bit lip hard.
Reality—not hentai. Unprepped sex hurts both. Losing it and hurting her? Eternal regret. First time tainted forever, forgiveness or not.
Off the bed to cool—
"Haa... Set the table and you still can't eat... ---------------."
"---------------."
⟨ Truth Serum ⟩
Her voice snapped control. Vision blurred—next, I was supine. Her astride my crotch.
Hips grinding lightly, sly smile, sultry voice:
"This big... and you didn't just shove it in? Virgin nerves? Whatever. If you won't pounce, I will."
