Noona's Midnight Binding Assault
I carefully slipped the blindfold over my noona's head while she slept soundly, her breaths soft and even. Then I slowly bound her arms and legs to the bedposts at the edges. Her chest rose and fell with each breath, her breasts shifting enticingly. Through the thin running shirt-like top clinging to those mounds, her nipples poked out prominently. The shirt had ridden up, exposing her smooth belly and cute little navel, while her slightly lowered panties revealed her hips. Pink cotton panties with a small cute ribbon and a clear cameltoe slit at the crotch. Anyone seeing my noona like this—defenseless panties on display, no bra under that thin top, limbs and vision completely restrained—would want to fuck her senseless.
"Mm..." She let out a small groan, shifting uncomfortably against the bindings. Even that feeble sound from her delicate woman's throat was music to my ears.
For the final touch, I carefully climbed on top of her and stuffed the gag into her mouth.
"...?" Like before, she didn't immediately grasp the situation even after waking with her mouth forced open around the gag. Clink. She tried to move her right arm, and the handcuff on that side rattled with a metallic chime.
"..!" Only then did she realize her limbs were shackled, eyes and mouth sealed, and someone straddling her. She thrashed wildly, finally piecing it together. As if she could snap the cuffs, she strained so hard the bed creaked loudly. I leaned close to her ear and whispered in a modulated, disguised voice.
"Stay still unless you want me to creampie you right now."
She flinched.
"Mmph..?" It was like she was questioning if she'd heard right, mumbling through the gag.
"Mmph.. mmph mmph..!" Soon she resisted even harder. She'd probably thought it was just me messing around until the voice changer kicked in, realizing her mistake.
"Well, it's the basement, so scream all you want—it won't matter. But if you do, you think we'll treat you nice?"
She froze, finally going quiet. Her body just trembled faintly now.
I placed my hand on her full, heaving breasts. I'd groped these so many times I should've been bored by now, but the rape scenario made it thrilling all over again. As I kneaded them freely, she shuddered violently, breathing raggedly. Not from fear or arousal—no, it was pure rage she couldn't contain, her body shaking and breaths heaving. From her perspective, some stranger was groping my exclusive tits like they were his.
"Mmph--!" I pinched a nipple lightly, and she let out a sharp protest, like don't you dare.
"Don't want me touching?"
"Mmph!"
"Heh heh, then what about this?" I swung my thick cock down, slapping it against her pussy like a sumata tease.
"Mmph..! Mmph mmph mmph!! Mmph!!" She screamed through the gag like that spot was off-limits, like she'd kill me if I touched it.
"Why? This pussy off-limits?"
"Mmph!! Mmph mmph!!"
"Heh heh heh, so stay still then? Before I creampie you and knock you up."
"....Mmph.."
Her blindfold started soaking with tears.
I'd save the pussy for later. Straddling her chest, I wedged my cock between those massive tits.
"Mmph.."
She made a small, resigned sound, which I took as permission. Grabbing the twin mounds, I rubbed them all over my shaft. Teasing the head against her nipples, stroking the pillar with the soft flesh—I used noona's breasts purely for my pleasure. Kidnapping and raping my own blood sister at night felt even dirtier than last time. Next time, Mom or little sis, I vowed, then sprayed my load across her face.
"Mmph..! Mmph!!"
Feeling the throbbing in her cleavage and the hot splatter on her face, she seemed to guess what happened, protesting through the gag. But when I slipped fingers into her pussy, she shut up fast. Like she'd protect that hole at all costs—which only made me want to violate it more.
I didn't shove in yet. Just rubbed my cock along her slit like sumata. Even that had her spasming and wailing. Her clit tingled with itchy pleasure as I probed her asshole with a finger.
"Mmph..! Mmph mmph mmph!! Mmph--!!!"
She started thrashing again, so I lined up with her pussy and thrust in.
"Mmph..! Mmph.. hmph.. huff.."
Realizing her pussy was being raped, her voice dripped with watery despair. Maybe from tension, her walls clenched tight. Squeezing and releasing rhythmically—almost like she was doing it on purpose. But seeing her blindfold soaked, body twitching as she sobbed, probably not.
Women can't feel it in their pussies anyway, so I started using my blood sister's hole at my whim. Squelch, squish. As I rocked my hips bit by bit, my precum made lewd wet sounds. Noona's pussy hadn't leaked a drop—probably 'cause she thought I was a stranger. It was a bit snug, but keep pistoning and her juices started flowing.
While I enjoyed her pussy, she trembled her shoulders, stifling sobs. Just a bit more and finish, I thought, continuing the bound rape of my big sis. I never held back my urges, so I creampied her right away.
"Mmph..?! Mmph! Mmph mmph mmph!!! Mmph!!"
I pinned her flailing body with brute force and kept thrusting. Slap! Slap! Hands gripping her hips to hold her down, hips slamming to spear her pussy relentlessly. Her walls milked me, clenching and releasing over and over. Then I came inside again.
"Mmph... mmph.."
She'd given up reacting, going limp and obediently offering her pussy.
"Not fighting anymore? You'll get pregnant like this, y'know."
"Mmph.."
Her muffled shut up cut off quick. She ignored further taunts, but her body jerked with each creampie, blindfold growing wetter—she was conscious, alright. I groped her tits while raping her, dumping load after unauthorized load into my crying noona. Dozens of times. She stopped reacting entirely, resigned even to impregnation. Her lower belly bulged from the cum flooding her womb. Pulling out made a pop and semen gushed out.
"Mmph.."
Thinking it was over, she made a sound.
"Whew... next up.."
Ending it here would've been no different from last time. Of course I had other plans—that's why I'd paused midway. The other plan?
"Mmph..?! Mmph.. mmph mmph.. mmph..!"
Squelch. Raping her asshole.
"Mmph---!"
The tight grip and texture were worlds apart from her pussy, welcoming me. She clenched desperately to expel the intruder, but it only felt better. Squelch. And it primed me for an anal creampie.
"Mmph..! Mmph mmph!"
Translation: Don't cum in there, you fucking psycho!!
Round two: anal raping my blood sister. No way I'd stop at her resistance—I pounded her ass mercilessly, just like her pussy. The difference? She was vocal as hell.
"Mmph..! Mmph.. mmph mmph.. hmph.. mmph..!"
Unlike her pussy, her sensitive asshole being violated forced the sounds out. Plus, noona's ass was already trained to my cock. Even if she didn't realize it was me, her hole recognized my dick. So I ravaged it freely, sending massive pleasure through her. She wailed high-pitched through the gag.
"Hmph.. huff..! Mmph.. hmph.. mmmph.."
"Feels good, huh? Heh heh, cumming from getting raped—you're one perverted bitch."
"Mmph!! Hmph..♡?! Mmph..! Huff..♡"
She bristled at my words like I'd hit a nerve, but soon devolved back to bitch-in-heat moans. I buried my face in her huge tits and just thrust. No more trembling at anal creampies, no more tears. Her brain was pickled in endless ecstasy.
She has no idea it's me, but her body falls for my cock instantly... what do I even call that? I bet if I untied her now, she'd fuck back eagerly.
"Hmph..♡ Huff..♡ Hmmmph... mmph.. hngh..♡"
I dumped five loads in her guts, then unbound her limbs and removed the gag.
"You fucking bastard..!"
Noona tackled me, blindfold still on, pinning me despite not seeing.
"You goddamn fuck..! Think I'd play whore just 'cause you growl like that? Fuck.. fuck.. you think my body's for scum like you to enjoy?! It's.. it's all my little bro's... fuck, my womb, ass, tits—they're all my bro's, you fucker!!"
Our eyes met as she ripped off the blindfold, spitting curses.
"....You son of a—."
Squelch.
"Hngh..♡?! Hey, fuck, I'm pissed off—!"
Squelch squelch squelch.
"Hngh..♡ Haa.. haaang.. You fucker haa..♡"
I got jumped and reverse-raped right there. The sun was up by the time she let me go..
"Fuck.. haa..♡ Hngh.. Your cock's so fucking good again..♡ Hngh.. Feel good?"
"Yeah, fucking amazing."
"Pfft, good then, fuck.. haa.. My belly hurts like hell now.. How many loads did you dump.."
Like last time, she forgave me quick once I said I was satisfied. Generous for a rape victim, but hey, I'm the perp.
"Hey.. if you got any conscience, help clean up.. ahh.. Eyes hurt from crying.. throat's sore.. ass is burning.."
We tidied till breakfast. Mom even washed the cum-soaked sheets midway, praising me after hearing the story. Told me to use the family however I want. A mom praising her son for raping his sister at night. A sister forgiving her rapist bro 'cause he enjoyed it. Not a shred of weirdness in this world.
