I slammed the door behind me, the humid Mumbai air still clinging to my skin from the market.

My sister Priya was in the kitchen, her back to me, wearing that thin cotton salwar that hugged her ass like it was painted on. At 22 she was all curves and fire, same age as me, and we'd been circling this heat for months.
"Fuck, Priya, you know what you're doing walking around like that," I growled, dropping my bag.
She turned, eyes flashing. "Shut up, Rahul. Mom and Dad are out till late. You gonna stand there staring or do something?"
That was all it took. I crossed the room in two steps, grabbed her waist, and yanked her against me. My cock was already rock hard in my jeans, pressing into her belly. She felt it and moaned low.
"Been thinking about this all day," she hissed, hand diving straight to my crotch. She squeezed my dick through the denim. "This fat cock needs to be in my pussy."
I spun her around, bent her over the kitchen counter, and yanked her salwar down. No panties. Her brown ass cheeks spread, and her shaved cunt was already glistening. "Look at this wet desi pussy. My own sister's cunt dripping for me."
"Fuck me already," she snapped, pushing back. "Don't tease."
I unzipped, pulled my thick cock out, and rubbed the head up and down her slit. She was hot and slick. One hard thrust and I buried myself balls deep in my sister's tight hole. Priya cried out, gripping the counter.
"God, yes! Fuck your sister! Pound that pussy!"
I did. Raw and fast, hips slapping against her ass, the wet sounds filling the apartment. Her walls gripped me like a fist. Every thrust made her tits bounce under her top. I reached around, found her clit, and rubbed it hard while I fucked her.
"Take it, you dirty girl. Your brother's cock owning this cunt."
She pushed back harder, meeting every stroke. "Harder, Rahul! Make me come on your dick!"
I slammed into her, the counter creaking. Sweat dripped down my back. Her pussy started pulsing, and she came with a loud moan, juices running down my balls. I didn't stop. I pulled out, spun her, lifted her onto the counter, and shoved back in face to face.
Her legs wrapped around me. I fucked her deep, watching her face twist with pleasure. "You love your brother's cock, don't you?"
"Yes! Fuck yes! Fill your sister up!"
I felt my balls tighten. I drove in one last time and exploded, pumping thick ropes of cum straight into her cunt. She milked every drop, clenching around me.
We stayed like that, panting. Then she grinned. "Round two in the bedroom. This time I ride."
The night stretched out. We fucked on the bed, on the floor, her riding me reverse so I could watch my cock disappear into her creamy pussy. She sucked me clean after, tasting our mixed juices, then begged me to eat her out while she came again on my tongue. By morning we were sticky, sore, and already planning how to sneak more free Indian incest sex stories into our lives whenever the parents were gone.
It was filthy, it was wrong, and it was exactly what we both needed.
