I never planned to fuck my sister. It just happened one humid summer night when our parents were out of town and the house felt too damn empty. Lisa was twenty-two, home from college for the break, and I was twenty-four, stuck working local construction. Wed always been close, but that night the air between us changed.
We started with beers on the back porch. She wore this tiny tank top that barely covered her tits and these cutoff shorts that rode up her ass every time she moved. I caught myself staring at the way her nipples poked through the thin fabric. She noticed and smirked.
You looking at my tits, big brother? she said, voice low and teasing.
Fuck off, I muttered, but I didnt look away.
She leaned forward, letting the tank top gape. Its okay. Ive seen you looking before. At the pool. In the hallway when I come out of the shower.
My cock twitched in my jeans. Lisa, dont start that shit.
Why not? She stood up and stepped between my knees. Were both adults. No ones here. Ive thought about it too.
She grabbed my hand and put it on her breast. Her nipple was hard under my palm. I squeezed without thinking, and she moaned. That sound broke whatever was left of my resistance.
I yanked her tank top down and sucked one nipple into my mouth. She tasted like sweat and beer. Her fingers went straight to my zipper, pulling my cock out. It was already rock hard, leaking at the tip.
Jesus, its thick, she whispered, stroking me. Bigger than I imagined when I touched myself thinking about you.
I stood, spun her around, and bent her over the porch table. Those shorts came down fast. She wasnt wearing panties. Her pussy was shaved smooth and already wet, lips glistening in the porch light. I ran two fingers through her folds, then pushed them inside. She was tight and hot.
Fuck me, she begged. Right here. Dont make me wait.
I lined up and slammed into her in one thrust. She cried out, pushing back against me. Her cunt gripped my cock like it was made for it. I fucked her hard, the table scraping across the wood. Every slap of my hips against her ass made her moan louder.
Tell me its wrong, she panted. Tell me youre fucking your little sister.
Its wrong, I growled, pounding deeper. Your pussy shouldnt feel this good wrapped around my dick.
She came first, legs shaking, juices running down my balls. I didnt stop. I pulled out, spun her to face me, and lifted her onto the table. Her legs wrapped around my waist as I drove back in. We kissed messy and desperate while I fucked her. Her tongue was in my mouth, tasting herself on me.
I carried her inside like that, cock still buried deep. We made it to the living room couch before I dropped her onto it and kept going. Missionary this time, so I could watch her face while I ruined her. Her tits bounced with every thrust. She reached down and rubbed her clit, coming again with a scream that echoed off the walls.
Cum inside me, she demanded.
Fill your sisters cunt.
I lost it. I buried myself to the hilt and unloaded, pulse after pulse of thick cum pumping into her. She milked every drop, hips rolling to take it all.
We didnt stop there. That night turned into days. In the shower the next morning I ate her pussy until she squirted on my tongue, then fucked her against the tiles while hot water poured over us. She rode me on the kitchen counter later, grinding her clit against me until we both came again. Every time I slid into her it felt dirtier and better.
By the time our parents came home we had rules: no marks, no getting caught, and absolutely no stopping. We still sneak it whenever we can. Her pussy is the best Ive ever had, and knowing its my sisters makes every thrust that much hotter.
She texts me sometimes now when shes back at school: Thinking about your cock. Come visit soon. I always do. And every time I walk through her apartment door shes already wet and ready, legs spread, waiting for her brother to fuck her senseless again.
