65. Secretly Silent
It was deep into the night, past midnight. Even the sound of the wind was blocked by the windows, leaving utter silence. The TV noise that had been audible until recently had long since faded away. I turned off the light in my room and stepped out into the living room. It was dark. Mom must have gone to bed in the master room ages ago.
...This should be fine.
I stopped by the bathroom to wash my hands thoroughly, then grabbed a towel to dry them off as I headed to the room next door. I knew it was crazy even as I thought about it, but honestly, I couldn't hold back anymore. It hadn't been that long, but she'd teased me way too many times.
I turned the doorknob so slowly it made no sound at all, then nudged the door open just a crack.
The lights were off, but the moonlight seeping through the window was enough to make out shapes clearly. I carefully closed the door behind me and released the knob. The click of the lock sounded dangerously loud, like it could make my heart pound right out of my chest. I swallowed hard, steadying my racing pulse, and crept toward the bed on tiptoe.
My little sister was buried under a mountain of blankets, fast asleep. ...It felt like forever since I'd last seen her wearing an eyemask like that.
"...".
I tossed the towel I'd brought onto the bed. For a split second, I wondered if she was faking it, but her breathing told me she was really out. I hadn't exactly planned on waking her... but I'd told her I was coming tonight, and she'd said it was okay. And yet here she was, stealing my T-shirt instead of her pajamas and blocking out her vision completely. What the hell was that supposed to mean?
...It's like she's saying, do whatever you want.
Fine then. Time to give her exactly what she wants.
I peeled back the blankets without shaking them too much. The usual Roccatie top, the usual dolphin pants. Nothing new, but damn if it didn't get me going anyway. Her breasts rose and fell with every breath she took. I gently placed my palm against one. ...No bra.
I started kneading and pinching, then held back for a moment. She still hadn't woken up.
I knew it was the kind of twisted, dog-pervert, trash idea she'd call me out for, but I didn't think she was wrong. Trash or not, I wanted to savor my defenseless little sister.
I climbed onto the bed. She was still breathing softly and steadily, deep in sleep. I pushed up her T-shirt. The underside of her breast came into view. I folded it higher. Her pale breast and plump pink nipple were exposed.
I barely restrained the urge to bite right in and stripped off my lower half completely. My cock was already throbbing hard from the sight alone. I debated just slipping it into her sleeping mouth, but nah. Too wasteful. Her mouth was virgin territory. If I could, I'd want her first blowjob to be one where she looks up at me with those eyes rolled back, servicing me properly.
No point wasting prime ingredients. I put them back in the fridge for now. Instead, I tugged her pants down. The elastic band slid between her ass and the sheets, gradually revealing more skin. Unlike the top, she was wearing panties—plain gray ones, nothing flashy like last time. Somehow, the normalcy made it even hotter.
I peeled the panties down to her thighs, exposing her pussy. That place I'd touched, defiled, dominated—mine alone. Bald and innocent-looking, but the body attached to it was so slutty it overrode every psychological taboo of her being my sister. Even after pounding it countless times, it still clenched tight and prim.
How far could I go before she woke? Even if she did, how long would she pretend to sleep? I couldn't contain my curiosity.
I massaged the insides of her thighs like a gentle rubdown. Her legs parted naturally, bit by bit. I pressed both thumbs between them, spreading the delicate inner flesh. The mucosa looked so fragile it might tear if handled roughly. Hard to believe my cock fit all the way in there—it was that narrow. To add some wetness to the still-dry entrance, I buried my face in.
You said you'd do it for me too, right? My turn.
Maybe it was the lust talking, but there was no bad smell. Maybe you'd prepared it for me.
"...Ngh."
Her breathing started to waver. Half-asleep or faking? Hard to tell. I stuck out my tongue just a little to test. I didn't plunge it into my exclusive hole. No need—instead, I tapped her clit, the spot that always made her melt. Her whole body twitched.
Her breaths came ragged now, too uneven for sleep. But she was still pretending to stay still, which was so damn cute I rolled my tongue over it. I lapped upward until the flat of it pressed against her, then flicked the tip downward. Matching her breathing rhythm, I licked persistently and thoroughly.
Finally, like she'd woken from the pleasure, her face flushed as her mouth fell open.
I pulled away from her for a moment. That was enough foreplay for you. But I wasn't heated up enough yet.
I took her limp hand from the bed, lacing our fingers. Her palm against my aching cock, I gripped it hard enough to cut off circulation. Wrapping my much larger hand around her smaller one, I stroked faster than I'd licked her. It wasn't her doing the work—no strength from you, just me jerking off to the feel of you. Using my sleeping sister's hand as a fleshlight.
Even that disgusting thought was just fuel for my arousal now.
I gripped her hand tight and shook it wildly, but she showed no sign of waking. I tormented her to the point where it was weird she hadn't stirred, even as wet squelching sounds filled the air. It pissed me off a little. You're the one always seducing me. So why dump all the guilt and depravity on me?
I'd suffered through those feelings over and over, alchemizing the pain into pleasure until my brain broke. I wanted to vent that rage, be forceful this time. Not even the kisses you love.
I spread the towel from earlier under my hips and flipped her onto her stomach. Her pants and panties tangled at her thighs. The curve from ass to hips to waist—delectable. Forbidden fruit I knew I shouldn't eat. But I'd tasted it so many times already, and for the rest of our lives, only I—her blood brother—could have it. I reached for it again.
My cock, desperate to claim the bitch in front of me, plunged mercilessly into her now-slick pussy. Afraid she'd moan, I clamped a hand over her mouth, but her insides welcomed me without resistance, like they'd been waiting. Her walls quivered like a pet greeting its owner home.
"Hng... ah...".
She let out a weak moan, too hard to keep pretending. I wanted to ignore it and pound her like a dog, but I couldn't. My heavy breaths sounded too loud, and slamming in would make the bed creak loud enough to leak outside.
So I pressed my cock deep inside. Grabbing her outstretched arms, I pulled them toward me. We'd always clung sticky and sweaty during sex, so looking down at our joined bodies like this felt new. Her pussy, sealed shut like no one else should enter, stretched wide around my cock like it might tear—it fed my dark urges for dominance and possession perfectly.
I slowly withdrew my fully buried cock, savoring the walls clinging to the head like they missed me. Once only the tip remained, I thrust back in at the same pace. Her depths accepted her big brother's cock without resistance, like it belonged there.
To avoid getting caught, I fucked her slow enough not to make her cry out—but the stimulation was lacking. Not enough to cum, but if I ramped up to satisfy the urge, I wouldn't stop even if she reacted dangerously.
So I pulled out with just the tip in. Using the twitching walls' grip as spice, I grabbed my sister-slicked shaft and jerked hard. You had no idea what was happening with the eyemask on, but this was my idea of consideration. Big-brother-trash style.
I gripped until it hurt and stroked furiously; the urge to cum built. When my balls tightened, I released my hand, shoved her head down, and buried her face in the pillow to muffle any sound. A little risky, but I thrust deep enough to make the bed groan. Even pounding down to keep her from bucking up, her hips followed me each time I pulled out.
And yet she stubbornly kept pretending to sleep. Infuriating. Adorable. I wanted to crush her. Kiss her. Do whatever I wanted, like it was my right—and she offered no resistance, no rebellion, no sign of dislike or pain. Just lay there feigning sleep, handing everything over and leaving it to me.
"...Kim Gyeo-ul."
"...".
"If you meet someone else, I'll kill them."
"...".
I confessed my filthy desires and true feelings to my sleeping sister. Normal people would freak, but we're both half-broken siblings. I pinned her shoulders and head, so she couldn't nod, but like she was happy, her pussy clenched tighter around me.
Her pussy that I'd defiled with my cum countless times, that I'd defile again and again, that only I would defile forever—I ravaged it mercilessly, without her consent, just beyond the wall from where Mom slept.
"Hoo...".
"...O...ppa."
"What...? When did you wake up? I thought you were asleep."
I'd filled her insides and collapsed on top when she finally stirred. I played dumb too—it was more fun that way.
"You like secretly fucking your sleeping little sister...?"
"...Yeah. Fucking hot."
She'd picked up another line to piss me off from somewhere, but her stammering delivery—clearly unpracticed—made it endearing. Because I knew it was for me, something she wanted to do.
"What about you? Did you like it?"
"...Too sleepy to know. Wanna sleep."
Her voice trembled as she shut her mouth again. She didn't take off the eyemask until I finally left the room. ...Though I begged for kisses several times in between.
