I slammed the door behind me after a long day at the site, sweat still clinging to my skin. The house was quiet except for the low hum of the fan in the hall. My little sister, Anjali, was home from college for the summer. At twenty-two she had filled out in all the right ways, her curves showing through the thin cotton nightie she wore around the house.
I was twenty-eight, back living under the same roof while I sorted out a new job in Hyderabad, and every night I fought the urge to stare at her round ass when she bent over.
That evening she was in the kitchen, chopping vegetables, her back to me. The nightie rode up just enough to show the bottom curve of her cheeks. No panties. My cock twitched in my pants.
"Anjali," I said, voice low. "You cooking for both of us?"
She turned, smiling, but her eyes dropped straight to the bulge already pushing against my zipper. "Anna, you look tense. Want me to help you relax?"
I stepped closer, grabbed her wrist and pulled her against me. "Stop teasing. You know what you've been doing, walking around like that."
Her breath hitched but she didn't pull away. "What if Amma comes home early?"
"Then she'll see her son fucking his sister raw." I spun her around, bent her over the counter, and yanked the nightie up to her waist. Her pussy was already glistening, lips puffy and wet. I freed my cock, thick and veined, and rubbed the head up and down her slit.
"Fuck, you're dripping," I growled. "Been thinking about your brother's dick all day?"
"Yes," she moaned. "Put it in me, anna. Stretch my cunt."
I didn't wait. I shoved in deep on the first thrust, burying every inch inside her tight heat. She cried out, gripping the counter as I started pounding her hard. The sound of skin slapping skin filled the kitchen. Her juices coated my shaft, dripping down my balls with every slam.
I reached under, found her clit and rubbed it fast while I fucked her. "This pussy belongs to me now. Say it."
"It's yours," she gasped. "My brother's cock owns my cunt. Fuck me harder."
I did. I pulled out, flipped her onto the counter, spread her legs wide and drove back in. Her tits bounced under the thin fabric. I ripped the nightie open, sucked one dark nipple hard while I kept thrusting. She wrapped her legs around me, heels digging into my ass, pulling me deeper.
Sweat ran down my back. Her walls clenched around me, getting tighter. "I'm going to come," she whimpered.
"Come on your brother's dick," I ordered. She shattered, pussy pulsing, juices squirting around my cock. I kept fucking her through it, chasing my own release.
When I was close I pulled out, stroked once, and shot thick ropes across her stomach and tits. She rubbed it into her skin, licking her fingers clean while staring at me.
We heard the gate outside. Amma was back. Anjali slid off the counter, pulled her nightie down, and whispered, "Tomorrow night, come to my room. I want you to fuck my ass next."
I tucked my cock away, heart still pounding. The forbidden heat between us had only just started.
