Jake had wanted his little sister's ass since the day she turned eighteen. Living under the same roof made it impossible to ignore. Sarah was twenty now, all curves and attitude, and every time she bent over in those tiny shorts, her round cheeks swallowed the fabric like they were begging for a cock. He knew it was wrong, but wrong felt good when his dick got hard thinking about stretching her tight hole.
One humid Saturday night, their parents were out of town. Sarah was in the kitchen wearing nothing but an old tank top and panties that barely covered her ass. Jake walked in, already half-hard from watching her earlier. "You keep shaking that thing at me, sis," he said, voice low and rough. "One of these days I'm gonna take it."
Sarah turned, smirking but blushing.
"Maybe I want you to. You've been staring at my ass for two years. Think you can handle how tight it is?"
That was all it took. Jake grabbed her, spun her around, and yanked the panties down. Her ass was perfect, pale and firm, the crack deep and inviting. He dropped to his knees and spread her cheeks, staring at the pink, puckered hole he'd dreamed about. "Fuck, look at that tight little ring. Gonna wreck it."
He licked her first, tongue dragging over her asshole, getting it wet and sloppy. Sarah moaned and pushed back against his face. "Taste good, big brother? Eat my ass before you fuck it." Jake growled and pushed his tongue inside, fucking her hole with it while his fingers found her pussy, already dripping. She was tight everywhere, but her ass clenched like a fist around his tongue.
When she was panting and pushing back, he stood up and freed his cock. It was thick and veined, the head already leaking. He spit on it and rubbed the head against her asshole. "This is gonna hurt at first, sis. Your tight ass is too small for this dick."
"Do it," she hissed. "Fuck my ass. Make it yours."
Jake pressed forward. The head popped in with a wet sound, and Sarah gasped, her ring stretching wide around him. Inch by inch he sank into her, feeling every ripple of her tight walls gripping him. "Goddamn, you're squeezing me so hard. This incest ass is mine now."
He bottomed out, balls pressed against her, her hole stretched obscenely around the base of his cock. Sarah's legs shook. "It's so big… fill my tight ass, Jake. Pound it."
He started thrusting, slow at first, then harder. The sound of skin slapping filled the kitchen. Her ass rippled with every slam, the tight ring clinging to his shaft on every pull. Jake reached around and rubbed her clit while he fucked her ass raw. "You love your brother's cock in your shitter, don't you? Dirty little incest slut."
"Yes," she moaned. "Harder. Wreck my tight ass."
He bent her over the counter and really let go, driving deep, his cock disappearing into her stretched hole again and again. Sweat ran down his back. Her ass was so tight it felt like it was trying to push him out, but he forced his way in every time, turning her moans into screams. When he reached under and felt her pussy, she was soaking the floor.
Jake pulled out, flipped her onto the table, and lifted her legs. He shoved back into her ass in one thrust, watching her face twist with the mix of pain and pleasure. "Look at you taking it. Your tight ass was made for family cock."
He fucked her like that until her eyes rolled back. Then he pulled out, flipped her again, and slammed back into her ass from behind, one hand fisted in her hair. "Gonna cum in this tight hole. Fill my sister's ass with my load."
Sarah pushed back, meeting every thrust. "Do it. Cum in my ass. Make it messy."
Jake buried himself to the hilt and exploded, thick ropes of cum pumping deep into her bowels. He kept thrusting through it, forcing his seed deeper while her ass milked him. Sarah came with him, her pussy squirting onto the floor, her ass clenching so hard it almost hurt.
They stayed locked together, breathing hard. Jake slowly pulled out, watching his cum leak from her gaping, used hole. Sarah reached back and spread her cheeks wider. "Look what you did to my tight ass, big brother. It's yours anytime."
Jake grinned, already getting hard again. "Good. Because we're not done tonight. That hole's getting another load before morning."
Sarah smiled over her shoulder. "Then stop talking and fuck it again."
