She was already naked on the bed when I walked in, legs spread, fingers sliding through her wet pussy like she owned the place. "Lock the door, big brother," she said, voice low and filthy. "Mom and Dad are gone for the weekend and I need that cock right now."
I didn't hesitate. Pants hit the floor and my dick was out, thick and hard, already leaking for her. She was my sister, twenty-three, tight body, tits that bounced just right when she rode me. We'd been fucking for months, ever since that drunken night after her birthday when she climbed into my lap and whispered how wet her cunt got thinking about me.
I climbed between her thighs and slammed into her in one thrust. She was soaked, tight as ever, gripping me like she was made for it. "Fuck yes," she moaned, nails digging into my back. "Pound your sister's pussy. Make it yours."
I fucked her hard, hips snapping, the wet slap of skin on skin filling the room. She wrapped her legs around me, pulling me deeper, and I gave it to her, balls slapping against her ass with every stroke. "You like that, you dirty little slut?" I growled, grabbing her hair. "Beg for your brother's cum."
"Give it to me," she panted, eyes glassy. "Fill me up. I want it leaking out of me all night."
I flipped her onto her stomach, yanked her hips up, and drove back in. Her ass looked perfect from this angle, cheeks spreading as I buried myself balls-deep. I reached around and rubbed her clit fast and rough while I pounded her. She came hard, screaming into the pillow, cunt clenching and pulsing around my cock.
I didn't stop. I kept fucking her through it, chasing my own release. When I was close I pulled out, flipped her again, and shoved my dick between her tits. She pushed them together and I thrust a few times before unloading all over her face and mouth. She licked it up greedily, swallowing what she could, then sucked the head clean.
We weren't done. She pushed me onto my back and straddled my face, grinding her dripping pussy on my tongue while she sucked me hard again. I licked her clit and tongue-fucked her hole until she came a second time, thighs shaking around my head.
Then she sank down on my cock reverse-cowgirl, riding me slow and deep at first before picking up speed. I watched my shaft disappear into her over and over, shiny with her juices. "Such a good sister," I said, smacking her ass. "Taking every inch like a whore."
She came again, then climbed off and got on all fours. "Fuck my ass," she demanded. I spat on her hole, worked a finger in, then two, before pressing the head of my cock against it. She pushed back, taking me inch by inch until I was buried in her tight ass.
I fucked her ass steady and deep while she rubbed her clit. When I came I stayed inside her, pumping load after load into her. She collapsed forward, breathing hard, my cum already starting to leak out.
We lay there catching our breath. She looked over her shoulder with that wicked grin. "Round three in the shower?"
I was already getting hard again. "Get in there and spread your cheeks."
The weekend was just starting.
