Chapter Title: Into the Stepsister's Mouth
-----------------------------------------------------------------
Seo-hyun, who'd been sucking my cock deep into her mouth for ages, flashed a sleazy grin.
"About to blow? Your dick's throbbing like fucking crazy. You fucking retard, were you seriously gonna cum in my mouth? Just try it. I'll despise you for real."
Seo-hyun smirked and stuck out her tongue before shaking my cock wildly.
"Gross. Look at that horny dog face you're making. Little sis grabs your dick and jerks you off, and you don't even resist—you're loving it?"
I closed my eyes.
"Was gonna cum quick and crash, but you're so fucking bad at it, might as well just sleep."
"Bullshit. Your dick's ready to explode right now? You're gritting your teeth, holding back 'cause it'd bruise your ego to cum in my mouth. Look at all that pre-cum leaking out."
Truth be told, she was right. It felt like my load was gonna erupt any second.
But every time her soft tongue wrapped around my shaft, it felt too damn good—I wanted to savor it more.
"Oppa wanted his dick sucked that bad? Tried it once and got hooked, huh?"
"Quit bullshitting. I'm letting you drain this buildup specially, so you don't head off to the MT and slut around again?"
I gave her a cute little smile.
"No excuses. How do you even think of sneaking a suck while I'm sleeping, you psycho?"
"Says the girl whose pussy's twitching and dripping hot on my leg?"
"Hide that scorching pussy rubbing against my leg before you yap. I'm the one sucking—why're you about to cum?"
Seo-hyun's face flushed red.
"What're you saying, you perv? It's hot under the covers, that's all. You were feeling the heat down there too? Fucking disgusting."
"Disgusting, but why can't you let go?"
"It's 'cause of your backed-up dirty dick juice filling your head with gross thoughts. Relieve that lust, and you'll snap out of it even if you regret it later."
Seo-hyun took my cock back in her mouth.
Okay, now it's getting risky.
I looked down. There was Seo-hyun, totally focused on slurping away.
Sensing my gaze, she glared up at me. Then she smirked and went at it even harder, the surge of ejaculation hitting me full force.
"Hey, hold up. Gonna cum—stop."
Seo-hyun shook her head like hell no, grinning around my shaft as her tongue worked overtime.
She gripped it tight with both hands and jerked furiously. I couldn't hold out anymore.
"Seriously gonna blow."
With my cock still in her mouth, she mumbled, "Hold it. Cum and you're dead, retard."
"I warned you, you didn't pull off. Means you want it in your mouth, right? If you're that thirsty for oppas cum, here it comes."
If she spat it out in surprise when it erupted, it'd be a total disaster—blankets and all.
To head that off, I grabbed her head.
I felt her flinch under my grip, but no way was I letting go.
The second I saw her pupils tense as she looked up at me, my urethra clenched and the floodgates opened.
"Mmph...! Gllrk!"
"Don't pull off. I warned you three times."
My cock twitched for what felt like forever, pumping out cum until her cheeks ballooned like a chipmunk.
Finally, I let go of her head.
"That's what you get for messing with me while I was sleeping."
Seo-hyun scowled hard, glaring daggers at me.
Wonder if she'll swallow. If she does, she'll get horny again and I'll tease the shit out of her.
Right then, she spat the load into her palm with a splurt.
"Damn, even though I came, that's a ton. Must be mixed with your spit?"
"Haa... You really shot in my mouth? Are you insane? Fuck, it reeks of cum. Ugh, I'm gonna hurl."
"Go puke and sleep it off."
Seo-hyun deliberately lifted her palm to her nose and sniffed.
"Eww... so fucking nasty... Way thicker than when you blasted my face. Super gross. How do you cum buckets just from your sis sucking you?"
"Not 'cause of you—pure physiology."
"Liar. You went feral, grabbed my head, bucked your hips like a dog-dick bastard."
She slapped my cock with her other hand—the clean one.
"Check this out. Rock-hard right after blowing a load. If it wasn't reacting to your sis, would it stay up like this?"
"I'm just healthy."
Seo-hyun ignored me, narrowing her eyes like she'd spotted something weird.
"Hold up... what the...? Did I see that wrong?"
Like she needed to confirm, she slapped my cock again.
"Holy shit... you freak... You know it twitches and gets even bigger every time I slap it? You're such a fucking perv... ultimate disgust."
"No, that's... just physiology, I swear?"
Seo-hyun tuned me out.
"Now you're getting hard from your sis slapping it around? You like this shit? Crazy horny perv dog-dick."
Her face looked kinda excited as she smacked it a few more times.
"Fucking psycho... It's harder now than before you came..."
"Told you, I'm healthy—it reacts to touch. Quit stimulating it and fuck off already. Looks like it'll stay up all day."
Seo-hyun glanced at her cum-filled palm, then grinned at me.
"You came it, so... open up."
"Ugh, please. Cut the crazy talk, go dump it in the bathroom and wash your hands. Clean up properly."
"You look like you need the cleanup more. Still leaking after all that? Ew... you're such a fucking perv."
She gave my cock one last smack and stood up.
"Letting you off 'cause MT's tomorrow. Perv bastard."
I flipped her the bird.
"Chung-hyun showed up too? Didn't think you'd come."
The seniors swarmed me the second we met on MT day.
"Can't miss out on team bonding."
I flashed smiles even at the ones not my type, keeping my image polished.
Just act eager, and they grin wide, asking if I need anything.
Same with my peers and juniors—no difference.
"Chung-hyun, wanna grab ice cream together?"
"Sunbae... up for a quick walk...?"
"Would've been boring as hell without you today."
The cheesy lines wouldn't leave me alone. Except for one person—Yoo Nara.
Hmm, she's grating on me.
The sunbae I was actually into gave me the bare minimum courtesy—no chit-chat, no signs of interest.
She's got that pride thing going, huh?
She's a woman too, so deep down, she's probably more obsessed with me than anyone.
Reason she plays it cool? She's popular herself—top of the department, alpha female.
Bet she'd fold if I teased her a little, but acting all high-value is kinda cute.
Still, I'm not gonna chase blatantly. The second I do, I'd be just like all these others fawning over me—no tension left.
That was when it happened.
"Nara sunbae. Mind giving me some quick advice on a dilemma?"
One of my peers mustered his courage. Decent-looking guy—not worried, whatever.
In this world, no matter how gentle or aloof a girl acts, give her a shot at dick and her pussy's soaked.
"Not a big deal. You seem a little buzzed though— you good? Won't forget if I counsel you? Here, drink this."
Nara sunbae handed him some hangover relief.
Look at her playing sweet.
Before long, they vanished from my sight.
Curious what they'd talk about. But no need to tail them—he'd bring back the results anyway.
His face when he returned said it all. Hell, even his shoulders said it—slumped straight down.
She trashed Choi Tae-min?
Didn't catch how he approached, but it must've been rough rejection.
In my past life terms, a total knockout junior hitting on you, and she builds an iron wall? Never lived as a hot guy back then, so who knows what goes through their heads.
Does she have a boyfriend right now? Nah. What, a lesbian then?
If boyfriend, I could steal her. Lesbian? Game over.
I pondered seriously. Any way to figure this out?
Asking around wouldn't confirm it. Even digging up past boyfriends? Useless.
Past life had plenty of gays in fake relationships too.
First things first—does she have a boyfriend?
Hell, it'd be better if she did.
Then, the rejected peer's chat with another buddy tickled my ears.
"What, she has a boyfriend?"
"Nah... Confirmed with another sunbae she was single, then I went for it..."
I couldn't help but frown.
Single? Why the fuck! With that face, why single?
No boyfriend and rejects a handsome peer? Lesbian odds just shot up.
"Then why?"
Yeah, spill it!
"Nara sunbae... said she likes someone..."
"What? Didn't say who?"
"No way she'd tell me that..."
I thought for a split second.
Maybe me?
Shook my head. There'd be signs.
Guys from my past life couldn't hide crushes to save their lives.
Alphas different?
No experience there, but couldn't rule out her liking a girl.
Please let it be me, and she's just an alpha who hides it well...
Then it hit me—alpha female liking someone inside without expressing? Doesn't add up. Despair sank in.
Not me then... No vibes, not even a hint...
I glanced over at Yoo Nara.
She's pretty as fuck, no denying it.
My standards are sky-high now, and she still clears them. Plus, she doesn't look easy—makes me want her more. I hardened my resolve.
Lesbian or not, I'll seduce her and fuck her at least once.
With that thought, the method appeared. Confirm if she's a lesbian and fuck her in one go.
