5. Lee Hayun Wants to Be Treated Like a Big Sister (3)
Meanwhile, Lee Hayun's mind was overflowing with a single thought: What do I do now?
She'd messed up right from the start. If she had to make excuses, it was because this was all so new and she was nervous. ...S-saying "let's have sex." Boldly seducing him with "I want to fuck you right here"—it was nothing like the endless simulations she'd run alone in her head, words she just couldn't force out so easily.
And... right before stepping into the infirmary, she'd bumped into the principal emerging from inside, phone to his ear.
Her plan had gone completely off the rails.
The only people who might show up at the infirmary right now—excluding herself—were maybe one or two at most. But factoring in the teachers? The risk of getting caught skyrocketed. Someone could knock in the middle of everything. Worst case, another person might overhear her embarrassing moans...
Those thoughts raced relentlessly through her mind, making her heart thump so loud it echoed in her skull. Today, I'm gonna lead like a proper big sis! That single-minded cheer had carried her here grinning ear to ear.
But her backup plan was pure naivety: If it looks risky, just lock the door! Would that even work? And soundproofing... how the hell...?
"...Ah..."
Right then, Seo Woojin's firm shoulder brushed against her.
Locked infirmary door. Just the two of them, a man and a woman. One bed.
...Her body went rigid.
"Mind if I sit next to you?"
"...F-fine. Doesn't matter..."
"Excuse me, then. Noona."
"......"
Shouldn't you say that before sitting down...?
Whatever. Was it cologne? A cool, refreshing scent she'd never caught from her chattering girlfriends tickled her nose. She'd never smelled anything like it from her guy friends, either... Weird.
...Anyway. No turning back now... She had to do it.
...Sex.
"......"
He was already sitting on the bed. Bolting with a "Actually, I can't!" wouldn't be very noona-like. She'd just have to finish quietly. Block her own mouth if she had to. If anyone outside heard... she'd really bite her tongue off.
First things first... lead with a kiss...
"Not much time, so I'll make it quick."
"......Mmph."
...Too late again. She'd meant to say something naughty first this time.
Self-reproach pulled Lee Hayun's gaze to her fingertips. A hand much larger and firmer than a woman's, gripping hers tight.
"Where exactly does it hurt?"
Nowhere hurt at all. Total fake-out. From the way he'd locked the door just now, he clearly knew it was bullshit too.
Everything was just theater.
At this point, screw it! She could pull the two condoms from her pocket, toss them on his thigh, and let the mood take over naturally...
...But somehow, ending the act felt impossible.
"P-pinkie... the tip..."
"The tip, huh."
If she did that, it'd turn into yesterday's sloppy mess again. Her, the so-called noona, lying obediently under her little bro, moaning all embarrassed...
Sure, it felt amazing—good enough to replay in the tub for ages last night—but!
She had to steer things right now. No matter how inexperienced she was, she couldn't keep getting tossed around by a younger guy forever. Pride swelled up. She was still a year older, after all.
Show any more shame, and her noona dignity would hit rock bottom.
Act like a noona. Leisurely attitude... Leisurely vibe... Leisurely...
"......"
Her eyes flicked back to her fingertip. Seo Woojin beside her let out a soft sigh, and a warm energy seeped faintly into her finger.
...He knew damn well it was fake, yet here he was, playing along and healing earnestly.
Seo Woojin from yesterday at his place had felt bolder. Ah, got it. Even the smooth operator was embarrassed in a spot like this. Made sense—he was only twenty. Same age as Jiyoon, grinding games at home right now.
So no need for her to freak out. Just act natural like planned, and she'd seize control easy...
Haah, haah. Lee Hayun took deep, audible breaths right next to the seated Seo Woojin. Ignoring her odd behavior with closed eyes, he accommodated her—until a small shadow fell over his lap.
Self-proclaimed noona had plopped right down on it.
"W-Woojin-ah."
"Yeah."
"Um..."
"Um...?"
"...Noona prepared a little present."
The die was cast. All that was left: move calmly as planned. No more getting dragged like yesterday. Show that leisure.
Gulp. Swallowing hard, Lee Hayun murmured,
"...Today, noona's gonna make you feel good..."
She dipped her head lightly.
"......"
"......"
Lips met lips. Then parted. Met again. Parted.
Just that? The infirmary basked in warm sunlight, utterly silent.
Eyes squeezed shut, Lee Hayun wrapped her arms around Seo Woojin's neck and pressed her lips to his. She'd been holding her breath, so each separation brought a soft exhale—emboldening her with This isn't so bad after all. She tentatively slipped her tongue out, licking awkwardly at his lips.
Was this right? Doubts nagged, but she ignored them and kept at it. Best fan service a hero could give a fan. Best reward for all his help. ...Best gift for the guy she'd stashed in her heart.
Maintaining those soft kisses, Lee Hayun eventually slumped her head onto his shoulder to catch her breath. Her cheeks burned so hot from just a little kissing; she needed a moment to cool off.
Ahem. She'd agonized over this one thing, but it was no big deal in practice. Did she finally look like a noona? Radiating that older-sis charm? Next: peel off Woojin's clothes layer by layer. I'm the noona, after all.
Cheeks cooled a bit, she lifted her head with a goofy grin.
"Mmph...?"
Without warning, Seo Woojin kissed her.
"Heuph...? Mmph......"
She was supposed to be on top...
...Right?
By the time she snapped to, her eye level matched Seo Woojin's. No—accounting for his slightly bent neck, she was actually a bit lower.
Why? A cold sensation under her ass explained: lost in the kiss, she'd slid off his thigh onto the bed. Now he loomed over her.
"......Phah.... Mm... Mmph...."
And so her one-year-younger "little bro" was on top again, just like last time.
"Mmph.... Nnghmuu......"
Tightly embraced, she took his kiss. Lips parted wide without resistance, tongues intertwined; sweet saliva dripped between their glued lips, ones she couldn't swallow fast enough. Her head, once filled with fresh sounds, now squeaked and squelched with sticky ones.
"Phah...! Ha...! Ah......?"
What was this? Same kiss... No. This one embarrassed her more, so un-noona-like.
Why was her heart pounding like it might burst from her throat?
...Weird... right?
No time for answers—wet lips overlapped again.
This was all wrong. Zero noona vibes, just clinging to his neck like a spoiled brat. Embarrassing. Gulping down his saliva like a perv. She had to seize control now. I can make you feel good toooo...
Wait... Just a sec... Wai...
"......"
"Pfft.... Haa...."
A sticky thread of saliva stretched between their lips. Foolishly sticking out her tongue, Lee Hayun looked up to meet Seo Woojin's gaze.
Warm eyes. The problem: they looked at her like a cute pet.
Like he was watching her perform tricks...
...Ego-crushing.
...He thinks I suck at kissing, the noona who can't even...
...I'm dead. For real.
"Again. I'm doing it again..."
"...Yeah? No time, though. You sure?"
Playtime over. She climbed back onto his thigh, dropping her head. Ignoring the ponytail slipping over her shoulder.
Just for the kiss.
"You're cute enough normally, noona."
"Sh-shut up.... Gotta get my revenge......"
...Exactly.
Swallowing her words, she pressed their lips together.
No more elementary-school lip pecks. She shoved her tongue between like he'd done to her, even teasing his neck with her lips—playing along with his leisure.
...Hickey. No clue how, but pressing lips should do it. Cover him in them. He'd need a scarf to go outside.
Tons.
"......Ngh...."
Mid-kiss frenzy on his neck and tongue, a soft touch grazed her ass, chills racing up her spine.
Seo Woojin's fingers. The same ones that had tenderly touched her pinkie moments ago.
Now they casually hiked up her defenseless uniform skirt, bunching the fabric at her waist to expose her pure white panties.
...For him to toy with at will. Her "little bro," playing with his noona's body.
"Chup.... Phah.... Mmph...."
Don't. My turn.
Even protesting with frantic tongue-twisting changed nothing. Seo Woojin gazed up casually, accepting her kisses. His fingers now lightly stroked over her panties.
...No biggie. Not that good... Right? Just rubbing over panties—something she'd done to boredom since middle school. Ignore it...
".... Ahak..., Wai.... Wait......?"
Ignore it?
"There, ...! ......"
She'd tried.
"Said you'd get revenge."
"Ki.... Ki......"
"...Not kissing?"
"Y-you keep, touching weird......"
"Weird?"
"......"
"Can't hear you. Noona."
"......"
His thick fingers probed her down there so weirdly... Way better than solo play, prodding poke... poke...
Nothing left but to bury her forehead in his solid shoulder, hips twitching helplessly.
Her, the older noona. Pathetic.
Lightly cumming with her face shoved in his shoulder, she heard,
"...Lift your head."
"Hic.... He...?"
That pleasant baritone thrummed into her flushed ears. Unthinkingly, she raised her face a bit.
"Chup.... Phah.... Mm...."
Just like last night at his place. Like the time before with Jiyoon in the bathroom, pretending to sleep while grinding cheeks.
Slowly receiving his saliva, then—when their mixed drool pooled at the back of her throat—
Gulp, gulp. Sweetly quenching it down.
Noona, my ass.
She'd wanted to look leisurely, laid-back...
...But dragged like a leashed pet, so vulgarly. Hoisted up... legs wrapping his waist... laid on the opposite bed.
Gulp... gulp.
