The apartment door clicked shut behind me and there she was, my little sister Lisa, now twenty-three and standing in nothing but a thin tank top and panties. I had come home for the weekend like always, but this time the air felt thick the second I saw her. She smiled that same crooked smile she had since we were kids, only now her tits strained against the cotton and her nipples poked out hard.
“Missed you, big brother,” she said, voice low. She stepped close and hugged me, pressing those soft tits right into my chest. My cock twitched instantly. I tried to laugh it off but my hands slid down to her ass without thinking. She didn’t pull away. Instead she ground her hips once, slow, feeling how fast I was getting hard.
“Fuck, Lisa,” I muttered. “You know what you’re doing.”
She looked up at me, eyes dark. “Been thinking about this for months. You left for college and all I could do was rub my pussy thinking about your cock. Now you’re here. No parents. Just us.”
I didn’t answer with words. I grabbed her hair, pulled her head back, and kissed her hard, tongue pushing deep. She moaned into my mouth and reached down to squeeze my dick through my jeans. Her fingers worked fast, unzipping me, pulling my thick cock out. It sprang up heavy and already leaking.
She dropped to her knees right there in the hallway. “God, it’s bigger than I remembered.” Her tongue licked the head, tasting the precum, then she opened wide and took me halfway down in one sloppy suck. I groaned and thrust forward, fucking her mouth while she gagged and drooled down her chin. Spit ran over her tank top, soaking it so the fabric clung to her nipples.
I pulled her up, spun her around, and bent her over the kitchen table. The panties came down in one yank. Her ass was round and perfect, pussy already shiny and dripping. I slapped her cheek hard enough to leave a red handprint, then lined my cock up and shoved inside. She was tight, hot, and soaked. I buried every inch in one thrust.
“Fuck yes, brother,” she gasped. “Use that pussy. It’s yours.”
I fucked her rough, hips slamming against her ass, the table creaking. Each stroke made wet sounds echo through the apartment. Her tits swung under the tank top until I yanked it up and grabbed them, pinching her nipples while I pounded deeper. She pushed back to meet every thrust, begging for more.
We didn’t last long that first time. I felt her cunt clamp down as she came, screaming my name, and I emptied my balls deep inside her, pumping thick ropes of cum until it leaked out around my cock. We stayed like that, breathing hard, my dick still twitching inside her.
Later that night we moved to the couch. She climbed on top, riding me slow at first, then faster, grinding her clit against me while my cum from earlier mixed with her juices and ran down my balls. I flipped her onto her back, spread her legs wide, and fucked her until she squirted, soaking the cushions. We kept going until the sun came up, switching positions, using every hole, talking filthy the whole time.
By morning we were both sore and sticky, lying naked on the living room floor. Lisa curled against me, one hand lazily stroking my half-hard cock.
“Next weekend again?” she whispered.
I slid two fingers back into her cum-filled pussy and smiled. “Every weekend. This pussy belongs to me now.”
She moaned and spread her legs wider, already ready for round three.
