92. The Answer
I couldn't see Gyeo-ul's face, but it didn't matter. No answer was even needed. At some point, we had become the kind of pair who couldn't refuse each other's requests.
"...Oppa."
I reached out, grabbed her shoulder, and pulled her face into view. Her cheeks had already flushed red from just one beer. Words didn't suit the mood she liked, so instead, I brought my lips close. By now, we could read each other's thoughts without a single word. When she was mad, she'd bite my lips or tongue. When she was excited, she'd breathe into my mouth and shove her tongue in lewdly. So right now, it felt a little desperate. Our inner lips collided endlessly instead of our tongues, and I could taste the lingering beer in her mouth.
"...Gyeo-ul."
"Mi... ah. ...Thanks. ...For listening to my whining."
"I haven't answered yet?"
"...Wasn't the kiss my answer?"
"No."
I laid Gyeo-ul down as she straddled me and switched to our usual position. I spread open her pajama top, all its buttons undone, gripped her breasts with both hands, and sealed her mouth once more. This time, her mood seemed better than before; she tangled her tongue even more lewdly.
"...Ha... ah... Oppa."
"...Not done yet."
Droplets of alcohol-mixed saliva fell as I naturally slid my hand toward her pants. As my fingers hooked into her waistband along her side and pulled down, Gyeo-ul unexpectedly grabbed my wrist and stopped me.
"No, Oppa. Even if... Mom's sleeping..."
Was it a threat or temptation? Even as she voiced her refusal, her hand gripped my pants and underwear together, tugging them down.
"Not now. Mom's here..."
My rock-hard cock bent slightly before springing free, and my sister pushed away her crushing brother, bunched up the blanket behind her back, and propped herself up halfway.
"...You said no."
"So... um... I'll do it with my hand first... You granted my wish, so at least that much..."
Sex was too risky, so no. But handjobs were okay. Honestly, I couldn't see the difference, but I had no desire to refuse. It had felt plenty good last time too. Because I'd taught her that.
"Wh...when you're about to cum, I'll stop... so give me a signal or something..."
"...Where will you let me cum if I signal?"
"Somewhere that won't... dirty the bed..."
If I came like this, it'd stain not just her pajamas but the bed too, so I changed positions. Leaning back against the blanket with her, facing sideways to look at my sister. Without specifying where, as soon as I adjusted, she started jerking my cock with loud, wet sloshes.
"Wanna touch my tits...?"
"...Yeah."
I stared deep into her pupils, and embarrassed by the intensity, Gyeo-ul turned her head and offered her fully exposed breasts instead. I didn't refuse, wrapping one arm around her waist to pull her close while kneading her breast freely with the other five fingers.
"They're... really huge, Oppa... Is this normal...? Or are you just weird...?"
Unable to find somewhere to rest her fleeing gaze, Gyeo-ul finally fixed it on the cock she was stroking, gauging its length by eye.
"...How does this even... fit here...?"
She glanced at her navel, placed her free hand just below it, inhaled sharply, swallowed, and pressed firmly on her abdomen.
"It should hurt... this is weird."
"...It hurt at first."
"It did at first. But you kept messing with it, so now it doesn't hurt—it just feels strange..."
...I couldn't tell if she knew what she was doing or not, which only made me harder. Even if she did, it was all stuff I'd taught her.
"Now if you cum... right up against here... it feels so weird... I can feel yours twitching inside me..."
"...Different from before?"
"Before it felt... full? Anyway... now it's just... yeah."
"Why stop mid-sentence."
"...Dunno. Idiot. Pervert. Dog pervert."
She knew exactly what she was doing but wouldn't answer, so I pinched her nipple in annoyance. She let out a sharp hngh, then gripped my cock harder as if to say don't, jerking it with fierce, splashing sounds.
...Honestly, it was a bit dangerous, but not yet.
"...What, why not tell me to stop."
"It's... bearable."
"Your voice doesn't sound bearable at all, Oppa."
"...From this much?"
I bluffed like it was nothing, scratching her pride, and she pressed closer, blowing a whoosh into my ear. She nibbled and licked it just like I teased her.
"Ha... ah... Does it feel good... when your little sister... strokes your... cock...?"
As if asking if I could hold out like this, she provoked me with formal speech like I'd made her do before.
"...Dunno?"
"Mom's sleeping in the next room... and you're making your blood sister drink booze... and do dirty things... does it feel good...?"
"...Never made you. Never gave you booze either."
"Liar... always lying... You always cum inside your little sister... without a condom... buckets of it..."
Actually, I'd never said no condom.
"...Do you know how it feels... taking birth control pills every day...?"
I'd never told her to take them.
"Oppa... after you cum deep inside me... the next day, I always think... if I skip this... I might really get pregnant..."
She'd even refused when I suggested tying my tubes.
"I wonder what face you'd make if I skipped... You'd worry so much... but in the end, you'd take responsibility... and that makes me wanna... actually have it... Do you know how that feels when I take the pill?"
She brought up birth control—something I'd stopped thinking about because of her seductions—
"You hate condoms..."
"...Fucking trash... My little sister worries every day because of you... and you always blame me..."
Her handiwork taunted if I could endure this, pushing me to the brink.
"...Wanna cum...?"
"... ."
Instead of words, I answered with a kiss and a squeeze that'd leave handprints on her breast.
"Heh... eep..."
Her hand stopped the instant our tongues touched.
"Ha... ah..."
As soon as our lips parted briefly, the wet sloshing resumed. If this kept up, I'd really mess up, so I decided to give her an order.
"...Open your mouth."
"No... ."
She'd said she'd let me cum somewhere that wouldn't dirty the bed, but now refused even that.
"Why?"
"Mouth means I gotta rinse... tastes weird... and I drank... so no mouth..."
"...Then strip."
The only spot left if not her mouth.
"That'll make me scream."
She threatened screams at the suggestion. Though she didn't say no.
"If I cover your mouth, you can't scream."
"...Even if you seal it with a kiss... sound leaks through my nose..."
Maybe not a threat—
"It's so big and long... thrusting inside would make me writhe... even if I beg you to go slow..."
Her words were pure temptation.
"When you cum on top... pounding thump thump... bed creaking... I can't hold back those sounds... eep."
I silenced my sister's filthy mouth—who knew where she'd learned this—straddled her, pulled her pants halfway down, shoved her panties aside, and plunged my pre-cum-ready cock into her slick, tempting pussy.
"Hoo... oo..."
One move and I'd blow, so I buried it to the hilt and caught my breath. My sister, still with breath for formal speech, pleaded desperately.
"O...ppa... pants..."
"What."
"...Take my pants... all the way off... please..."
"...Why?"
"...Can't hug you like this..."
Her pajama pants hooked on my knees. Preventing hugs. After a moment's thought, I realized and lifted my hips as she helped, stripping them off completely. At once, she wrapped her arms and legs around me, shaking her hips wildly as she pleased.
"Ha... eek, Oppa... cover... my mouth..."
"... ."
I couldn't control her body anymore, so I gave in to instinct, sealed her lips, lifted her waist and ass to minimize bed creaks, held my breath to stifle even nasal sounds, and ravaged the spot she'd said felt too full.
"Mm... ph... mm."
She held back sounds and breath too, then expelled all the air inside her as I thrust deep to cling to her innermost wall, trembling head to toe just how she liked, and poured every burst of pent-up desire into her.
"...Haa... ah... Oppa..."
"...Hoo. ."
"Pervert. Dog pervert. I haven't even cum yet."
Of course—barely inserted before I finished, she was still full of energy, while I, exhausted first for once, couldn't retort as I gulped air.
"...Feel good?"
"...No, not at all."
"What... I said all those super embarrassing things on purpose."
"You didn't cum. Still not enough."
"If we go till you're satisfied, I'll really scream..."
"Doesn't matter. Worst case, we get caught and kicked out."
"Are you sane, Oppa...?"
"...You're the one who confessed wanting to ditch Mom and live together alone?"
"... ."
Showing her my wrecked state, she answered not with words but a kiss. I didn't refuse. Deeper this time, more carefully, I worked her insides—filled with my scent—until she was satisfied. No moans escaped, thankfully, but holding our breath to suppress them probably fried both our brains.
