I never planned on fucking my sister. But when she walked into my apartment that night in nothing but a thin tank top and panties, her nipples hard against the fabric, I knew the line was already crossed. "Lock the door," she said, voice low and dirty. I did.
She pushed me against the wall and grabbed my cock through my jeans. "I've wanted this for years," she whispered, squeezing hard. "No more pretending." I yanked her top up and sucked on her tits, biting the nipples until she moaned. She dropped to her knees, unzipped me, and took my cock straight into her mouth. No teasing. She sucked like she was starving, gagging on it, spit running down her chin while her hand worked the shaft.
"Fuck, sis," I growled, grabbing her hair and thrusting into her throat. She looked up at me with those eyes, mascara starting to smear, and moaned around my dick. I pulled her up, spun her around, and bent her over the kitchen table. Her panties were soaked. I ripped them aside and shoved two fingers into her pussy. She was dripping, hot and tight. "You want your brother's cock?" I asked, slapping her ass.
"Yes," she hissed. "Give it to me." I lined up and slammed in balls-deep in one thrust. She cried out, gripping the table edge. I fucked her hard, the sound of skin slapping filling the room. Her tits bounced with every stroke. I reached around and rubbed her clit while pounding her. She came fast, legs shaking, pussy clenching around me.
I didn't stop. I flipped her onto her back on the table, spread her legs wide, and drove back in. She wrapped her legs around me and pulled me deeper.
"Harder," she begged. "Fuck your sister like you mean it." I did. Sweat dripped off me onto her stomach. Her nails dug into my back. I felt her cum again, soaking my cock.
We moved to the couch. She climbed on top, sank down on me, and rode like she was trying to break me. Her ass slapped against my thighs. I grabbed her hips and thrust up to meet her. "Tell me how much you love it," I demanded. "I love my brother's dick," she panted. "I love getting fucked by family." That pushed me over. I flipped her onto all fours and took her from behind again, pounding until I filled her up, cum leaking out around my cock as I kept thrusting through it.
We didn't stop there. She sucked me hard again and we fucked in the shower, against the wall, water running over us while I held her up and drove into her. By morning we were sore, marked, and already planning the next time. No guilt. Just raw need.
