I slammed the door behind me and there she was, my older sister Priya, bent over the kitchen counter in nothing but a thin nightie that barely covered her ass. We were both adults, me twenty-five and her twenty-eight, but the house was empty and the heat between us had been building for years. "You left the door unlocked again," I growled, stepping close enough to press my hard cock against her from behind. She didn't move away. Instead she pushed back, grinding her round ass on my bulge.
"Fuck me like you mean it this time," she said, voice low and filthy. Her Tamil accent thickened when she got horny. I yanked the nightie up, exposing her bare pussy already glistening. No panties. She knew what she wanted. I spit on my fingers and rubbed her swollen clit in rough circles, making her moan and spread her legs wider on the cool tile floor.
Priya reached back and freed my cock, stroking it fast and tight. "Put it in your sister's cunt," she demanded. I didn't wait. I lined up and shoved inside in one hard thrust, burying every inch deep. She was soaking wet and tight, gripping me like she never wanted me to pull out. I fucked her right there against the counter, hips slapping loud, her tits bouncing out of the nightie with every slam.
She talked dirty the whole time. "Harder, anna, fuck your akka's pussy like it's yours. Fill me up." I grabbed her hips and pounded faster, the wet sounds of her cunt taking my cock filling the kitchen. Sweat ran down her back. I reached around and pinched her nipples, twisting just the way she liked until she cried out and came hard, her walls pulsing around my shaft.
I didn't stop. I pulled out, spun her around, and lifted her onto the counter. Her legs wrapped around me as I drove back in, watching her face twist with pleasure. "Suck my tits while you fuck me," she ordered. I leaned down and sucked one dark nipple into my mouth, biting gently while I kept thrusting deep. Priya's hands tangled in my hair, pulling me closer.
We moved to the floor when the counter got too hard. She got on all fours, ass up, and I mounted her from behind again, this time slower but deeper, grinding against her ass cheeks with every stroke. "Tell me how much you love your brother's cock," I said, voice rough. "I love it," she panted. "I love how you stretch me, how you make me come so fucking hard."
I reached under her and rubbed her clit again, feeling her get even wetter. She came a second time, shaking and cursing in a mix of English and Tamil, her pussy milking me. I couldn't hold back anymore.

I pulled out at the last second and shot thick ropes across her ass and lower back, marking her like I always wanted to.
We stayed there catching our breath, my cum cooling on her skin. Priya looked over her shoulder with a wicked smile. "Round two in the shower?" she asked, already standing and pulling me toward the bathroom. I followed, cock already twitching again. The night was just getting started.
