Lee Hayun Wants Big Sis Treatment (5)
"The revenge I couldn't get earlier... I'll continue it now...."
I spat it out curtly and climbed on top of Seo Woojin, my breasts fully exposed in a way that made me blush. My tits shook vulgarly between the gaps in my uniform shirt, but it was fine. Soon enough, Woojin, pinned beneath me, would be the one showing an even more embarrassing sight. It was fine. Just you wait.
'Sis, please stop,' or 'I was wrong'—until I heard something like that, I'd torment him plenty.
I knew a thing or two about what guys liked. What made them embarrassed. Pornhub had taught me everything since middle school...!
Until now, I'd been somehow dragged around on a leash by Seo Woojin. But from this moment on, things would be different. Think. Remember. How those blonde sisters in the videos handled guys. So, usually in situations like this, they'd go...
"Get ready...."
...Like that. I wiped my lips and leaned down, gripping the buttons of his pristine white shirt tightly.
...But this was looser than I expected...? Don't guys usually wear shirts that hug their bodies? Or not? I wasn't sure. All the guys around me were heroes—musclehead idiots who'd only grown their bodies.
Hmm. Seo Woojin wasn't a hulking mass of muscle; he had that lean, packed kind of build. Maybe that's why. They hated that "fashion muscle" look, calling it fake. Whatever. It wasn't like Woojin needed to crush anyone. He was a healing-type transcendent, after all.
I steeled myself and put strength into my fingers. The tight buttons popped open one by one with a click. Was it the silence? My heart pounded like it was about to die of shame, but I gritted my teeth and kept moving my fingertips. If I gave up now, it'd be just like last night at Woojin's place...
......
...No.
No way.
"Y-You like this too, huh? You're being so quiet."
"Ah. Yeah. Sure."
"R-Really...? Um...."
I blurted something out from sheer embarrassment, but his response was lukewarm. Honestly, I'd hoped for something more annoyed, like 'Sis, cut it out.' If he'd said 'Don't wanna?' all casually, and I'd kissed him while stripping him...
It would've looked just like those sisters in the videos. Too bad. No helping it. Ignoring the awkward vibe, I undid the half-open shirt completely.
...Last night, it had been too dark to see clearly. Now, his body was laid bare. Hidden under clothes, it didn't show, but surprisingly well-toned...
"......"
"......"
Not the time to gawk like an idiot. Those sisters barely glanced at guys' bodies. They went straight for the pants.
"Hoo.... Hoo...."
I exhaled the breath I'd been holding since who-knows-when and undid his belt. Pressed the button-like clasp, and it slid off with a soft whoosh.
"Ngh...."
In the quiet infirmary, the metallic clink of the belt spread around us. For a moment, dirty thoughts flickered, but since I was straddling him, I couldn't pull his pants down. I glanced around nervously and lifted my hips just a bit.
I just needed to get his dick out, right? No need to strip him fully? Yeah, pull 'em down a little, then climb back on...
"......"
"......"
Silently, I stared down at the thing I'd pulled out from his panties myself.
...Why was it so soft and floppy?
"...D-Do you not wanna fuck me?"
"What're you—"
"Guys, y'know, they get rock-hard just from stripping.... In the videos...."
"Guys?"
"Th-Those....... ...Porn......."
"Ah."
I knew there was a process called erection. I knew from sex ed that blood rushes to the spongy tissue when you're aroused, blah blah. So this situation made no sense. It meant my tits didn't turn him on at all.
In porn, black guys, white guys, Asians—anyone—would always pop a stiff one the second pants came off, poking relentlessly at the girl's belly.
...In that video Jiyoon found in my history, it was even...
No, forget it. Anyway. Why are you still soft...?
"You need stimulation for that. Don't even know that, 'Sis'?"
"...Last night, it was hard from the start."
"There was stimulation then."
"Stimulation...?"
"You know..."
He murmured quietly from his spot on the bed, his body slowly drawing closer. I flinched in surprise, trying to pull back, but his arm wrapped around my waist, leaving me helpless.
What? Not another kiss. No. This time, I'm doing it. You're drinking my saliva, not the other way around. I twisted my head away to block the kiss and reached out toward him.
But.
"Hik...."
I'd barely pushed against his manly shoulder when warmth touched somewhere else instead of my bitten lip.
Between my embarrassingly spread uniform. At the tip of my stiff nipple. Gently.
"...Ngh.... D-Don't...."
"...Didn't you say you didn't wanna fuck?"
It wasn't annoyance or bad vibes—it was pure shame that made me say it. But his perfectly logical reply left me speechless.
For sex, guys need to be sexually aroused. ∨ Woojin said stimulation was required. ∨ ...Guys weirdly love tits. They steal glances like crazy, pretending not to. ∨ Last night, during my first time, Woojin had groped mine first. ∨ Conclusion: Woojin likes tits.
...Come to think of it, to be a proper big sis, tits seemed important. In shoujo manga, big sis characters always had...
Huge boobs....
"......"
I clamped my mouth shut, saying nothing, as his breath drew near again. Over my bare breasts—no bra, no tee—his breath ghosted my skin. Not rushed. Not excited. Just quiet. Brushing my flesh.
...That alone made me swallow hard. All Woojin's fault. He'd given me this weird habit...
I'll pay you back for this debt...
"...Ngh...."
His slightly parted lips engulfed my tingling nipple.
I thought he'd suckle like a greedy baby, but no. He just lightly mouthed it, gauging my reaction. In porn, they licked sloppily or bit...
It tickled weirdly... Felt strange...
The unfamiliar sensation made me tilt my head aside innocently. Not to avoid a kiss this time—I just couldn't meet his eyes straight on.
...Yeah. A big sis shouldn't blush like this from her little bro's caresses.
I was still denying reality when...
"...Hic...."
My shoulders jerked at the new sensation. He licked it. Kneading my tits—the ones friends snuck peeks at—with one huge hand. His tongue tip on the other...
"D-Don't...."
Did it feel good? No clue. Porn sisters always sighed pleasurably during this. I pinched my nipples during solo play too...
But not at the 'feels good with a guy' stage yet. Just overwhelming shame. Couldn't even look at his face.
"Nngh...."
Head fully turned? My tits—similar size to Jiyoon's, no pride in them, but impossible to ignore under stares—were now his playthings.
Squeezed hard in his much larger hand. Blunt fingertips flicked my hardened nipples, making me stifle moans and twitch. Then he lapped gently around them.
A baby wouldn't lick like that. Just suck greedily. Silly thought—hoo, hoo—I steadied my breath.
...Now you'd get horny thoughts every nursing session. Like me now, twitching on his thigh.
"Hik.... Ah.... Hn...."
Thinking this was okay? His touch grew rougher. Fingers that flicked now pinched my nipples.
...Mysteriously, in my favorite way. Squeeze hard enough to hurt a bit, then release forgivingly. Let the lingering tingle savor the air on my tit tips. A shameful method I'd never admit to Jiyoon.
"Hoo.... Hoo...."
His tongue, merely circling before, pulled away for his teeth. Firmly. Not painfully. But suffocatingly so. Nose buried in my breast, he nibbled my cherry-pink nipple, leaving teeth marks...
Marking me. Then slowly pulled back.
A sidelong glance: a wet thread from my nipple tip snapped.
...That means.... His saliva that always filled my throat. Staring blankly, my nipple was reshaped again in his hand. One crushed in fingers. One chewed between teeth.
Twisted lewdly. My panties soiled.
"Nn, haah.... W-Wait...."
No. It felt good... I kinda wanted more...
But this strayed too far from my plan. I'm the big sis. And a hero. An older woman hero can't forever be leashed like a pet, panting after a villain.
Time to snap out of it and take control...
I squeezed my eyes shut, shoving his shoulder hard—
"......?"
Hot pulses tapped my lower belly: thump, thump. I froze mid-breath. Something hot... And insanely hard. Even the brief touch told me.
Not a virgin anymore. I knew what this was. Woojin's 'that.'
But something was off, spawning question marks in my head. My belly was warm. Fine so far.
...It was warm all the way to my navel.
Something hard kept prodding below my navel.
That warm...
"......"
My sideways gaze finally swung forward. Down.
"...Eh......"
I swallowed. Flashed back. Yeah, it was huge. I'd bookmarked and rewatched that one...
...The one Jiyoon found. As thick as that. Holding it in my hand felt unreal.
I remembered it plunging deep. How far did it go? Anxiously waiting, then my head smashed as he beastly pounded root-deep.
But I couldn't measure exactly. No ruler.
Guessed a little under a handspan.
But now, sitting on his thigh... It reached right below my navel.
Root-deep, it'd go there. Crystal clear now.
"...Sis."
"Y-Yeah?"
Staring dazed at the twitching cock, mind on that blonde taking it beast-mode, his voice snapped me back.
"What're you doing? Just sitting there."
"...D-Dunno...?"
"...Dick's hard now. Do whatever."
"...Huh?"
"Didn't you wanna fuck? Like a big sis."
"......"
"If not, like last night..."
"W-Wait."
"......"
"...I'll move, so just lie there...."
...Lee Hayun. You're the big sis. Not a perv... A big sis.
