The house was quiet except for the clink of ice in glasses and the low hum of the TV. Sarah and her older brother Mike had the place to themselves for the weekend. Their parents were gone, and the two of them had raided the liquor cabinet like they were still teenagers sneaking drinks. By midnight they were both drunk, laughing too loud, slouched on the big couch with half-empty bottles between them.
Mike poured another shot of whiskey and handed it to her. “You always get slutty when you drink,” he said, grinning.
Sarah knocked it back and wiped her mouth. “Fuck off. You get handsy.” She was already flushed, her tank top clinging to her tits from the heat of the room. No bra. She hadn’t bothered putting one on after her shower.
They kept drinking. The movie on the screen turned into background noise. Mike’s leg pressed against hers. Neither moved it. Sarah felt the warmth spreading between her legs, the kind that came from booze and the forbidden closeness. She looked at her brother’s mouth, then lower, at the bulge already showing in his jeans.
“Stop staring at my dick,” he muttered, voice thick.
“Stop getting hard then,” she shot back, but her hand was already sliding over his thigh.
Mike didn’t push her away. Instead he grabbed her wrist and pulled her hand straight onto his cock. “You started this shit. Finish it.”
Sarah squeezed him through the denim, feeling him throb. She was soaked already.

The room spun a little from the alcohol, but that only made everything hotter. She leaned in and kissed him hard, tongue pushing past his lips like they’d done this a hundred times. They hadn’t. Not sober anyway.
Clothes came off fast and messy. Her tank top went over her head. Mike’s mouth went straight to her tits, sucking one nipple then the other while his hand shoved down her shorts. He found her wet cunt and shoved two fingers inside without warning. Sarah moaned loud, grinding down on his hand.
“Fuck, you’re dripping,” he growled against her breast. “Little sister’s pussy is soaked for her brother’s cock.”
She yanked his jeans open and pulled his dick out. Thick, veiny, already leaking. She stroked him rough, thumb sliding over the head. “Shut up and fuck me then.”
Mike flipped her onto her back on the couch, yanked her shorts and panties off in one tug, and spread her legs wide. He didn’t tease. He lined up and shoved his cock into her in one hard thrust. Sarah cried out, back arching. He was big and she was tight from the angle, but the stretch felt perfect.
He started fucking her right there, deep and fast, the couch creaking under them. Skin slapped skin. Her tits bounced with every thrust. Mike held her thighs open and watched his cock disappear into her cunt over and over.
“Goddamn, Sarah. Your pussy’s gripping me like it wants to keep me inside.”
She reached down and rubbed her clit while he pounded her. “Harder. Fuck me like you mean it.”
He pulled out, flipped her onto her stomach, and hauled her hips up. Then he slammed back in from behind, one hand fisted in her hair. Sarah pushed back to meet every thrust, moaning into the cushions. The whiskey made everything feel distant and intense at the same time. She came hard around his cock, cunt pulsing, but Mike didn’t stop. He kept driving into her until she was shaking.
He pulled out again and dragged her to the floor on the rug. She got on her knees and took his cock into her mouth without being told, tasting herself on him. Mike fucked her throat while she gagged and drooled. When he was close he pulled her off, bent her over the coffee table, and sank back into her pussy.
They fucked like that for what felt like hours. Switching positions when one got tired. Mike on his back while she rode him, tits in his face. Her on all fours while he spanked her ass red. On the stairs halfway to the bedrooms. Every time one of them came they kept going after a few minutes, too drunk and too horny to stop.
By the time they finally collapsed on Mike’s bed, both of them were covered in sweat and come. Sarah’s cunt was sore and puffy. Mike’s cock lay heavy against his thigh, still half-hard. They lay there breathing hard, the alcohol haze starting to thin.
Sarah turned her head and looked at him. “We’re doing this again tomorrow night.”
Mike smirked, lazy and satisfied. “Yeah. We are.” He reached over and slid two fingers back into her messy pussy, slow and possessive. “And the night after that.”
She spread her legs wider for him and closed her eyes, already planning how much liquor they’d need to make it happen again.
