It started with a simple text. Jake was twenty-four, home from college for the summer, and his nineteen-year-old sister Emily had the house to herself while their parents were gone for the weekend. "Come over. Pool's empty and I'm bored as fuck." He showed up in board shorts and nothing else, already half-hard from the thought of seeing her in that tiny bikini she always wore around him.
Emily met him at the door in nothing but a thong and a cropped tank top that barely covered her tits. Her nipples poked hard against the thin fabric. "Took you long enough," she said, eyes dropping straight to the bulge in his shorts. "Been thinking about this all week."
They didn't bother with small talk. Jake grabbed her by the waist, spun her around, and bent her over the kitchen counter. "You want it raw, don't you?" he growled, yanking the thong aside. Her pussy was already slick, lips puffy and glistening. He spit on his fingers, rubbed her clit once, then shoved two fingers deep inside her. Emily moaned and pushed back against his hand.
"Fuck yes. Finger that cunt harder."
Jake didn't need more encouragement. He dropped his shorts, freed his thick cock, and lined up. One hard thrust and he buried himself balls-deep in his sister's tight pussy. Emily cried out, gripping the edge of the counter while he started pounding her from behind. The wet slap of skin on skin filled the kitchen. Her juices coated his shaft every time he pulled back, strings of it stretching between them before he slammed in again.
"Goddamn, your pussy's gripping me like it never wants to let go," he grunted, one hand fisting her hair, the other smacking her ass hard enough to leave a red handprint. "Been wanting to fuck my own sister for years. You knew it too, walking around half-naked like a little slut."
Emily pushed back to meet every thrust. "Shut up and fuck me harder, Jake. Fill your sister's cunt. I want to feel that cum dripping out of me all day."
He obliged. He fucked her like he hated her, hips snapping forward in brutal strokes until her legs shook. When she came, her pussy clamped down so tight he almost lost it right there. She squirted around his cock, soaking the floor and his balls. Jake didn't stop. He kept pounding through her orgasm until he felt his own balls tighten. With a low groan he buried himself to the hilt and unloaded, pumping thick ropes of cum deep into her spasming cunt.
They didn't even move to the bedroom right away. Jake pulled out, watched his cum leak down her thighs, then spun her around and lifted her onto the counter. He dropped to his knees and buried his face between her legs, tongue lapping up the mess he'd made. Emily grabbed his hair and ground her pussy against his mouth. "Eat it. Taste how fucking dirty we are."
He sucked her clit, tongue-fucked her hole, and shoved two fingers back inside while he licked. Emily came again, thighs clamped around his head, screaming his name.
When she finally let him up, she dropped to her knees and swallowed his cock straight down her throat. No teasing. She took him to the root, gagging and drooling, spit running down her chin while she bobbed fast and sloppy.
Jake fucked her face until he was hard again, then pulled her up and bent her over the couch. This time he aimed lower. "You want it in your ass too, sis?"
Emily reached back and spread her cheeks. "Do it. Stretch my asshole with that big cock."
He worked spit and her own pussy juice into her tight ring, then pressed the head of his cock against it. She hissed as he pushed in, inch by inch, until his balls rested against her pussy. Jake gave her a minute to adjust, then started thrusting. Slow at first, then faster, until he was railing her ass with the same filthy intensity he'd used on her cunt. Emily reached between her legs and rubbed her clit, coming again with his cock buried in her ass.
They spent the rest of the afternoon moving from room to room. He fucked her in the shower, water streaming over them while he held her up against the wall and pounded her pussy. They sixty-nined on the living-room floor, her mouth working his cock while he tongue-fucked her cum-filled holes. On the patio, with the sun setting, he took her from behind again, this time pulling out at the last second to paint her ass and lower back with another thick load.
By nightfall they were exhausted but nowhere near finished. Lying in bed, Jake pulled Emily on top of him. She sank down onto his cock, riding him slow and deep while they kissed like lovers instead of siblings. "This isn't a one-time thing," she whispered against his mouth. "I want your cock every day we're home."
Jake gripped her hips and thrust up to meet her. "Good. Because I'm not done using every hole you've got."
They came together one last time, her pussy milking him dry while she moaned into his neck. Afterward they stayed tangled up, his cum leaking out of her, both of them already planning the next round. The weekend had only just begun, and neither of them planned on stopping until their parents got home.
