I slammed the door shut behind us the second we got home from the bar. My sister Emma was already pulling her dress up over her hips, no panties on, her shaved pussy glistening under the hallway light. We had been teasing each other all night with looks and dirty whispers. Now it was time.
"Get on the couch, sis," I growled, yanking my belt open. "I want that pussy right now."
Emma dropped onto the cushions, legs spread wide, fingers already rubbing her wet slit. "Fuck me hard, big brother. I've been wet for your cock since dinner."
I dropped my pants and my dick sprang out, thick and throbbing. She reached for it, stroking fast, thumb smearing the precum over the head. "Suck it first," I ordered. She leaned in and took me deep, gagging as I fucked her throat in short thrusts. Spit ran down her chin onto her tits.
After a minute I pulled out and flipped her around. I lined up behind her and shoved my cock straight into her tight cunt in one hard push. Emma moaned loud, pushing back against me. "Yes, fuck that sister pussy! Fill me up!"
I pounded her deep and fast, balls slapping her ass with every stroke. Her walls gripped me, hot and slick. I reached around and rubbed her clit while I drilled her. "You like your brother's dick in your cunt, don't you? Say it."
"I love it," she gasped. "I love getting fucked by my own brother. Don't stop."
I flipped her onto her back so I could watch her face while I fucked her. Her legs went over my shoulders and I sank in even deeper. Her pussy made wet squelching sounds every time I bottomed out. I leaned down and sucked one nipple hard while I kept thrusting.
"Faster," she begged. "Make me cum on your cock."
I hammered her harder, the couch creaking. Her pussy started pulsing around me. She came with a sharp cry, juices squirting out around my shaft and soaking my balls. I didn't slow down. I kept fucking her through it, chasing my own load.
When I felt it building I pulled out just long enough to slap my wet cock against her clit, then slammed back in. "Gonna cum in your pussy, sis. Gonna fill that incest cunt."
"Do it," she moaned. "Pump it all inside me."
I buried myself to the hilt and unloaded. Thick ropes of cum shot deep into her, pulse after pulse. I kept grinding as I emptied every drop, her pussy milking me. When I finally pulled out, cum leaked out of her stretched hole and ran down her ass.
Emma reached down, scooped some up with two fingers, and licked them clean. "We should do this every night," she said, spreading her legs again so I could watch more cum drip out.
I was already getting hard again. "Turn over.
I'm not done with that pussy yet."
