Jake slammed the front door shut behind him, his cock already half-hard from the filthy thoughts he'd been having all day. His little sister Emily was home from college for the weekend, and the house was empty except for the two of them. She was 21 now, all grown up with big tits and a tight ass that drove him insane. He found her in the kitchen wearing nothing but a tiny tank top and panties, bending over the fridge.
"Fuck, Emily," he growled, grabbing her hips from behind. "You knew I'd see that ass and lose it."
She straightened up and turned, smirking. "Took you long enough, big brother. I've been wet thinking about your cock since I got here."
Jake didn't waste time. He yanked her tank top down, freeing her heavy tits, and sucked a nipple hard into his mouth while his hand shoved into her panties.
Her pussy was dripping, shaved smooth and hot. He shoved two fingers inside her and pumped them fast.
"Oh shit, yes," she moaned, grinding on his hand. "Finger that cunt, Jake. Make me cum before you fuck me."
He dropped to his knees, ripped her panties off, and buried his face between her legs. His tongue lashed her clit while he finger-fucked her deep, making sloppy wet sounds fill the kitchen. Emily grabbed his hair and rode his face, her juices coating his chin.
"Goddamn, you taste so fucking good," he muttered against her slit. "This crazy shit between us is the best."
She came hard, legs shaking, screaming his name. Jake stood, dropped his pants, and slapped his thick cock against her stomach. "Bend over the counter. I'm gonna wreck this pussy."
Emily obeyed, spreading her legs wide. Jake slammed into her in one thrust, burying every inch balls-deep. He fucked her like an animal, hips slapping loud, her tits bouncing as he pounded her from behind. "Take it, sis. Take your brother's cock."
"Fuck me harder!" she begged. "Make it crazy, Jake. Use me."
He pulled out, spun her around, and lifted her onto the counter. Legs over his shoulders, he drove back in, watching his cock stretch her tight hole. They went at it like that until he felt his balls tighten. He pulled out and shot thick ropes of cum across her tits and stomach.
But that was just the start. They moved to the living room couch for round two. Emily got on all fours and begged for it in her ass. Jake spat on her hole, worked a finger in, then pushed his cock inside. She screamed in pleasure-pain as he stretched her, fucking her ass raw and deep while reaching around to rub her clit.
"Shit, your ass is so tight," he grunted. "I'm gonna fill it up."
They switched positions constantly—her riding him reverse cowgirl, him pinning her legs back for deep missionary, her sucking his cock clean between rounds. Dirty talk flew nonstop.
"Call me your dirty little sister slut," she demanded while bouncing on his dick.
"You're my incest whore," he shot back, slapping her ass red. "This pussy belongs to me now."
By the third hour they were both covered in sweat and cum. Jake had her on the floor, legs spread wide, pounding her missionary while she begged for more. "Don't stop, brother. Keep fucking me crazy like this."
He came inside her this time, flooding her pussy, then pulled out and watched it drip out. Emily scooped some up and licked her fingers. They lay there panting, already planning the next round in her old bedroom.
The night stretched on with no end in sight—shower sex, bed sex, even a quickie against the hallway wall. Their bodies stayed locked together, raw and relentless, turning the weekend into one long, filthy celebration of exactly what they both craved. By morning they were exhausted, sore, and grinning, already knowing they'd do it all again the second the urge hit.
