Rahul slammed the door shut behind him, his cock already half-hard from the porn he had been watching on his phone all day. His parents were gone for the week, leaving him alone with his younger sister Priya in their Mumbai apartment. At 24 and 22, they were both adults who had been circling each other with dirty looks for months.
Priya walked out of her room in a thin cotton nightie that barely covered her ass. "What the fuck are you doing in there all day?" she asked, but her eyes dropped straight to the bulge in his shorts.
"Incest porn," he said flat out. "Indian brother-sister shit. You want to see?"
She didn't answer. She just stepped closer, reached down, and squeezed his cock through the fabric. "Show me."
Rahul pulled his shorts down.
His thick brown cock sprang out, veined and leaking. Priya licked her lips and dropped to her knees right there in the hallway. She wrapped her hand around the base and took the head into her mouth, sucking hard and noisy. Spit ran down his shaft as she bobbed, gagging herself on purpose.
"Fuck, Priya, your mouth is so wet," he growled, grabbing her hair. He fucked her face in short thrusts until tears streaked her makeup. She pulled off gasping, strings of saliva connecting her lips to his cock.
"My turn," she said, standing up and yanking her nightie over her head. Her full tits bounced free, dark nipples tight. She pushed her panties down, revealing a shaved pussy already glistening. "Eat me like those videos."
Rahul shoved her against the wall and dropped down. He spread her legs and buried his face between them, tongue lapping her slit from asshole to clit. Priya moaned loud, grinding on his mouth. "Yes, brother, lick that cunt. Make it sloppy."
He tongue-fucked her hole then sucked her clit until she came, thighs shaking around his head, juices dripping down his chin. She pulled him up and kissed him deep, tasting herself on his tongue.
They stumbled into the living room. Rahul bent her over the arm of the sofa, kicked her legs apart, and slammed his cock into her pussy in one thrust. Priya screamed, "Fuck yes! Stretch me!" He pounded her hard, balls slapping her clit with every stroke, her ass rippling. The wet sounds of fucking filled the room.
He reached around and rubbed her clit fast. "You like your brother's cock in your desi pussy?" he grunted.
"Harder," she begged. "Fuck me like the sluts in those incest porn Indian sex stories."
Rahul pulled out, flipped her onto her back on the sofa, and drove back in. He hooked her legs over his shoulders and jackhammered her, watching her tits bounce and her face twist in pleasure. Priya came again, pussy clenching tight around him, squirting a little onto his stomach.
He didn't stop. He flipped her again, this time on all fours, and took her from behind. His hands gripped her hips hard enough to bruise as he railed her deep. "I'm going to fill this cunt," he warned.
"Do it," she moaned, pushing back to meet every thrust. "Cum in your sister's pussy."
Rahul buried himself to the root and exploded, thick ropes of cum pumping into her. He kept thrusting through it, making it messy, cum leaking out around his cock and down her thighs.
They collapsed on the floor, breathing hard. Priya reached between her legs, scooped some of his cum onto her fingers, and sucked them clean. "Again?" she asked, already stroking his softening cock back to life.
Rahul grinned. "All week." He pulled her on top of him and slid back inside her cum-filled pussy, ready for round two.
