My sister walked into the kitchen wearing nothing but a tiny tank top and panties. At 24 she still had that tight body from cheerleading in high school, and I was 26 and already hard just looking at her ass cheeks hanging out the bottom of those cotton panties. We had the house to ourselves for the weekend while our parents were out of town. I didn't waste time. I grabbed her hips from behind and pressed my cock against her ass through my shorts.
"What the fuck are you doing?" she said, but she didn't pull away. Her voice was already breathy.
"Shut up and bend over the counter," I told her. I yanked her panties down to her knees and shoved two fingers straight into her pussy. She was wet as hell already. "You've been teasing me for years with those shorts and tops. Time to pay up."
She moaned and pushed back on my fingers. "Fuck, big brother, do it harder." I finger-fucked her sloppy cunt right there until her juices ran down my hand. Then I pulled my cock out, thick and throbbing, and slammed it balls-deep into her in one thrust. She cried out and gripped the counter.
I pounded her raw from behind, skin slapping loud and nasty. "Take that dick, sis. Your pussy feels so fucking tight." She reached back and spread her ass for me so I could watch my cock stretch her hole. Every thrust made wet squelching sounds because she was dripping. I reached around and rubbed her clit hard until she came, her cunt clamping down and milking me.
I didn't stop. I pulled out, spun her around, and shoved her to her knees. "Suck it. Taste your own pussy on your brother's cock." She opened wide and swallowed me down, gagging but not stopping. Spit ran down her chin onto her tits while she bobbed her head fast, sucking like a slut. I held her hair and fucked her face until tears ran down her cheeks.
Then I hauled her up, bent her over the kitchen table, and drove back into her pussy. I fucked her harder this time, slapping her ass red while I told her what a dirty incest whore she was. She begged for more. "Cum in me, please, fill your sister's cunt." I grunted and unloaded deep inside her, pumping thick ropes of cum until it leaked out around my cock.
We didn't even make it to the bedroom. I dragged her to the couch, flipped her on her back, and ate her pussy while my cum still dripped out of it. She tasted like sex and sin. Then she climbed on top, sank down on my cock again, and rode me dirty, grinding her clit against me until she squirted all over my stomach. We kept going all night, switching holes, positions, and filthy words until both of us were sore, sticky, and satisfied. By morning we were already planning the next time.
