I never planned to fuck my sister, but the second she walked into the living room in that tiny tank top and no bra, I knew we were both screwed.
It was just the two of us in the old house that weekend. Mom and Dad were gone until Sunday. Rachel was twenty-two, home from college for the summer, and I was twenty-four, crashing there between jobs. We'd always been close, but lately the looks had changed. Lingering. Hungry.
She dropped onto the couch beside me and stretched, her nipples poking hard against the thin cotton. "Hot as hell in here," she said, voice low. "You mind if I just chill like this?"
My cock twitched instantly. "Do whatever you want."
She smirked, like she already knew what I was thinking. "Bet you want to touch them."
I didn't answer with words. I reached over, cupped one full tit, and squeezed. She moaned, pushing into my hand. "Fuck, finally," she whispered. "I thought you'd never do it."
That was all it took. I yanked the tank top up and sucked her nipple into my mouth, biting just hard enough to make her gasp. Her hand went straight to my crotch, squeezing my cock through my shorts. "God, you're so fucking hard already."
We didn't make it to the bedroom. She shoved my shorts down, wrapped her fingers around my thick shaft, and started stroking me rough and fast. "I've wanted this dick for years," she said, eyes locked on mine. "Wanted to feel it stretch my pussy."
I stood, pulled her up, and bent her over the arm of the couch. Yanked her shorts and panties down in one move. Her ass was perfect, round and smooth. I slapped it hard, watching it jiggle. "Spread your legs."
She did. I spit on my fingers, rubbed her wet slit, and shoved two inside. She was dripping. "Look at this greedy cunt," I growled. "Already soaked for your brother's cock."
Rachel pushed back against my hand. "Stop teasing and fuck me."
I lined up and slammed in balls-deep in one thrust. She cried out, loud and filthy. I grabbed her hips and pounded her, the couch creaking under us. Skin slapping skin. Her pussy clenched tight around me every time I bottomed out.
"Fuck yes, harder," she begged. "Use that family pussy."
I reached around and rubbed her clit while I fucked her deep and fast. She came fast, shaking and cursing, juices running down her thighs. I didn't stop. I pulled out, flipped her onto her back on the couch, and shoved back in. Her tits bounced with every thrust. I leaned down and sucked them again while I drove into her.
We moved to the floor next, her riding me reverse cowgirl so I could watch her ass bounce on my cock. She reached down and played with my balls. "You gonna fill your sister's cunt?" she panted. "Pump me full of that hot load?"
I grabbed her waist and thrust up hard until I exploded, shooting rope after rope deep inside her. She came again right after, milking every drop.
We didn't stop there. We fucked in the kitchen against the counter, in the shower with her leg hooked over my shoulder, and finally in her old bedroom on the twin bed that creaked like crazy. By the time we passed out, sticky and sore, we'd lost count of how many times she'd taken my cum.
The next morning we woke up and did it again. Same raw, dirty need. We knew it was wrong. We just didn't give a fuck.
That weekend turned into our secret. Every chance we got after that, we found a way to sneak off and fuck like animals. Raw. Messy. Family.
