I pressed play on the Hindi audio sex story and the woman's voice filled the room, low and filthy, talking about a brother sliding his thick cock into his own sister's wet cunt. My dick was already hard in my shorts when the door opened and my sister Priya walked in. She was twenty-two, home from college, wearing just a thin tank top and shorts that barely covered her ass. She heard the audio right away.
"What the fuck are you listening to, bhai?" she asked, but she didn't turn it off. She stepped closer, listening to the voice describe a sister spreading her legs and begging for her brother's cum.
I didn't answer. I just looked at her. Her nipples were poking through the tank top. She noticed me staring and bit her lip.
"You like that shit?" she said. Her voice was rough. "Incest stories? You want to fuck your real sister like that?"
I stood up. My cock was tenting my shorts. "Yeah. I do. And you're standing there listening like your pussy isn't dripping."
Priya didn't run. She pulled her tank top off. Her tits were full and heavy, dark nipples stiff. "Then do it. Stop jerking off to audio and fuck me for real."
I grabbed her, spun her around, and yanked her shorts down. No panties. Her ass was round and smooth. I shoved two fingers between her legs and she was soaked, hot and slick. "Fuck, you're already ready for your brother's cock."
She moaned and pushed back against my hand. "Shut up and put it in. I want to hear you say it while you fuck me."
I dropped my shorts and my cock sprang out, thick and veined. I rubbed the head up and down her slit, coating it in her juices. Then I slammed in deep in one thrust. Priya cried out, gripping the edge of the desk.
"Harder, bhai," she gasped. "Fuck your sister's cunt like in those stories."
I pounded her. The wet sounds of my cock stretching her pussy filled the room along with the Hindi audio still playing. Every thrust made her ass ripple. She reached back and spread her cheeks so I could go deeper.
"Talk dirty," she demanded. "Tell me I'm your slut sister."
"You're my dirty little sister," I growled, slamming into her. "This tight pussy belongs to your brother now. I'm going to fill it with cum."
She came hard, her walls clenching around my cock, juices running down her thighs. I didn't stop.
I flipped her onto the bed, spread her legs wide, and drove back in. Her tits bounced with every thrust. She pulled me down and kissed me messy, tongue deep, moaning into my mouth.
"More," she begged. "Cum inside me. Make it real."
I fucked her faster, balls slapping against her ass. When I came I buried myself to the hilt and pumped thick ropes of cum straight into her cunt. She held me there, milking every drop, her own orgasm rolling through her again.
We stayed locked together, breathing hard. The Hindi audio had ended. Priya smiled up at me, cum leaking out around my softening cock.
"Next time," she said, "we record our own."
