She was already on her knees when I walked into the kitchen that night, her mouth open and waiting like she'd been planning it all day. "Lock the door," my sister hissed, eyes locked on my crotch. I did, then yanked my belt open. My cock sprang out hard and she didn't waste time. Her tongue dragged up the shaft in one long, wet lick, circling the head before she sucked me deep. "Fuck, your mouth feels so good," I growled, grabbing her hair and pushing in until her throat squeezed me.
She gagged but didn't pull back. Instead she moaned around my dick, spit running down her chin while her hand pumped the base. I pounded her face in short, rough thrusts, balls slapping her chin. "That's it, lick every inch like the dirty sister you are." She pulled off just long enough to say, "I want you to fuck me so hard I can't walk tomorrow." Then she went back to work, tongue swirling and licking the underside while I used her mouth.
I pulled her up, spun her around, and bent her over the table. Her shorts hit the floor and her bare ass was right there, pussy already glistening. I dropped to my knees and buried my face between her cheeks, licking from her clit all the way back to her tight hole. She tasted sweet and forbidden. My tongue fucked into her cunt while my fingers rubbed her swollen nub. She pushed back against my mouth, moaning loud. "Eat that pussy, big brother. Lick it good before you pound it."
I stood, lined up, and slammed inside in one thrust. Her walls gripped me like a fist. I didn't go slow. I pounded her hard, hips slapping her ass with every stroke, the table creaking under us. "Take that cock," I grunted, reaching around to pinch her nipples through her shirt. She pushed back to meet every thrust, pussy making wet sounds every time I bottomed out. "Harder," she begged. "Pound your sister's cunt like you mean it."
I flipped her onto her back on the table, spread her legs wide, and drove back in. Her tits bounced with each brutal thrust. I leaned down and licked her nipples, sucking one then the other while my cock kept hammering deep. She clawed my back, legs locked around me. "I'm gonna come," she gasped. I licked lower, tongue on her clit even as I fucked her, and she exploded, pussy pulsing and squeezing around my shaft.
I didn't stop. I pulled out, dragged her to the floor, and made her get on all fours. Then I mounted her again, pounding from behind while my thumb pressed into her ass. She reached back and spread herself for me, begging for more. "Lick me again," she panted. I pulled out, flipped her, and buried my tongue back in her soaked pussy, licking up all her juices before I slammed my cock home once more.
We kept going until sweat covered us both. I finally pulled out and she dropped to her knees again, tongue out. I stroked fast and shot thick ropes across her face and tongue. She licked every drop off her lips, then sucked the last from my cock. We stayed there catching our breath, knowing this was only the start of another long night of raw, dirty family fucking.
