The house was quiet except for the low hum of the AC. Jake stood in the kitchen doorway watching his sister Emily bend over the fridge in nothing but an old tank top and panties.
She was 22, he was 24, and they had been circling this for months.
"Stop staring at my ass," she said without turning around.
Jake didn't deny it. "It's right there. Hard not to."
Emily straightened up with a bottle of water and faced him. Her nipples were already hard against the thin cotton. "Mom and Dad are gone till Monday. We doing this or what?"
He crossed the room in three steps and grabbed her by the hips. "Fuck yes." His mouth crashed down on hers, tongue pushing past her lips while his hands slid under her tank top to squeeze her tits. She moaned into the kiss and reached down to grab his cock through his shorts, rubbing the thick length.
They didn't make it to the bedroom. Jake spun her around and bent her over the kitchen counter. He yanked her panties down to her knees and kicked her legs apart. "Look at that wet pussy," he growled, running two fingers through her slick folds. "You've been thinking about your brother's cock all day, haven't you?"
Emily pushed back against his hand. "Shut up and fuck me already."
He freed his dick, thick and veined, and rubbed the head up and down her slit before slamming in deep. She cried out, gripping the counter edge as he started pounding her hard. The wet slap of skin filled the kitchen. Every thrust made her ass ripple.
"Fuck, your cunt's tight," Jake grunted, one hand fisting her hair. "Better than I imagined."
"Harder," she begged. "Fuck your sister harder."
He did. The counter shook. He reached around to rub her clit in fast circles while he drove into her. Emily came first, pussy clenching around his cock, juices dripping down her thighs. Jake didn't stop. He kept railing her until his balls tightened and he unloaded deep inside her, flooding her with hot cum.
They weren't done.
He pulled out and spun her to face him, lifting her onto the counter. His cum leaked out of her as he dropped to his knees and buried his face between her legs. His tongue lapped at her swollen clit, then pushed inside to taste their mixed mess. Emily's hands tangled in his hair, holding him there while she ground against his mouth.
"God, eat that pussy," she moaned. "Taste how fucking dirty we are."
Jake stood, cock already hard again, and drove back into her. This time it was slower but still rough, his hands pinning her wrists above her head as he fucked her on the counter. She wrapped her legs around him and took every inch.
They moved to the couch next. Emily rode him reverse, bouncing on his dick while he smacked her ass red. "That's it, ride your brother's cock," he said, spreading her cheeks to watch himself disappear inside her. She reached down to play with his balls, squeezing just right until he was groaning.
Later, in the shower, he fucked her against the tile with hot water pouring over them. He held her up, her back to the wall, legs locked around his waist, pounding into her until she screamed his name. Cum ran down her leg when he pulled out.
By midnight they were in her bed. Jake had her on all fours, gripping her hips as he slammed into her from behind. "Tell me you want it," he demanded.
"I want my brother's cum," she panted. "Fill me up again."
He did, shooting another load deep in her pussy. They collapsed sweaty and spent, but not for long. Emily turned around and took his softening cock in her mouth, sucking him clean and getting him hard once more. She swallowed him to the root while he fingered her cum-filled cunt.
The weekend stretched ahead of them. They fucked in every room, raw and loud, no holding back. Brother and sister, finally giving in to exactly what they both needed.
