I clicked the link on a random night when I was bored and horny. The incest sex stories article popped up with its bold headline and a few teaser paragraphs about siblings who couldn't keep their hands off each other.
I should have closed the tab. Instead I read every filthy word while my cock got hard in my jeans. By the time I finished, my sister Emma was on my mind in a way that felt wrong and way too good.
Emma was twenty-three, two years younger than me. She still lived at home while she finished school. We had always been close, but nothing like this. The article had descriptions of sisters riding their brothers' cocks, wet pussies stretched around thick dick, cum dripping down thighs. I kept picturing Emma's ass in those tiny shorts she wore around the house.
A couple nights later we were alone. Mom and dad were out. Emma came into the living room wearing just a tank top and panties. Her nipples showed through the thin fabric. I couldn't stop staring.
"What are you looking at?" she asked, but she didn't sound mad.
"That article I read," I said. "The one about brothers and sisters fucking."
She laughed at first, then her face got serious. "You think about that shit?"
"Yeah. With you."
The room went quiet. Then Emma walked over, climbed onto my lap, and ground her pussy against my hard cock through my pants. "Show me," she said.
I yanked her tank top up and sucked on her tits. They were full and soft, nipples stiff in my mouth. She moaned and rubbed harder. I shoved my hand inside her panties and found her soaking wet. Two fingers slid right into her tight cunt. She was dripping, clenching around me while she whispered, "Fuck, that's it, finger your sister's pussy."
We didn't make it to the bedroom. I pulled her panties off, dropped my pants, and she straddled me on the couch. Her pussy was shaved smooth and pink. She grabbed my cock, lined it up, and sank down slow. The head pushed inside, then the whole shaft disappeared into her wet heat. She was tight and hot, gripping me all the way down.
"Fuck me," she said. "Fuck your sister like in that story."
I grabbed her hips and thrust up hard. Skin slapped. Her tits bounced. She rode me fast, grinding her clit against me every time she bottomed out. Juices ran down my balls. I reached around and rubbed her asshole with a wet finger. She came hard, pussy pulsing and squeezing my cock while she yelled my name.
I flipped her onto her back on the couch and fucked her deep. Legs over my shoulders, her cunt taking every inch. I pounded her until I felt my balls tighten. "Gonna cum inside you," I warned.
"Do it," she begged. "Fill your sister's pussy."
I exploded, shooting thick ropes of cum deep in her. She kept moving, milking every drop. When I pulled out, cum leaked out of her stretched hole and onto the cushion.
We didn't stop there. Later that night she got on her knees and sucked me clean, licking our mixed juices off my cock. Then I bent her over the kitchen table and took her from behind, watching her ass ripple while I slammed into her creamy cunt again. She came twice more before I pumped another load into her.
By morning we were still going. In the shower she soaped my cock and I fucked her standing up, water running over us while she begged for more. Her pussy stayed slick and ready the whole time.
We kept it up for weeks after that. Every chance we got we fucked like animals. Mornings before anyone woke up, late nights in her room with her face in the pillow so she could moan loud while I drilled her. She let me cum anywhere: down her throat, on her tits, deep in her ass after we worked a finger in first. The article had started it, but the real thing was better than any story.
Emma still wears those little panties around the house. Now when I see them I just pull them aside and slide right in. She always gets wet fast, like she was waiting for it. We both know it's wrong, but neither of us gives a fuck. The dirty secret only makes it hotter.
