She walked into the living room wearing nothing but one of his old t-shirts, the hem barely covering her ass. He was on the couch, legs spread, already half-hard from the way she looked at him. No small talk, no hesitation. She climbed straight onto his lap and ground her bare pussy against his cock through his shorts.
"Fuck, sis, you're soaked already," he growled, grabbing her hips and yanking her down harder. She moaned and reached between them, shoving his shorts down just enough to free his thick dick. Her hand wrapped around it, stroking fast and rough while she rubbed her wet slit along the head.
"Been thinking about your nut all day," she said, voice low and filthy. "Want you to pump it straight into my pussy like you did last night."
He didn't answer with words. He lifted her up, lined up, and slammed her down onto his cock in one thrust. She was tight and dripping, taking every inch like she was made for it. Her pussy clenched around him as she started bouncing, tits jiggling under the shirt. He yanked the shirt up and sucked hard on her nipple, biting just enough to make her cry out.
"Yeah, ride that dick," he muttered against her skin. "Milk me. I want to feel you cum before I fill you up."
She went faster, grinding her clit against him on every downstroke. The wet sounds of her pussy swallowing his cock filled the room. He slapped her ass hard, leaving a red handprint, then reached around to rub her swollen clit with his thumb. She came quick and loud, pussy pulsing and squirting a little around his shaft.
He flipped her onto her back on the couch without pulling out, hooked her legs over his shoulders, and started pounding deep. Every thrust made her tits bounce and her pussy squelch. "Gonna nut in you so hard," he said, voice rough. "Gonna flood this incest cunt till it's leaking down your thighs."
She begged for it, dirty and nonstop. "Do it, brother. Shoot that hot cum in my pussy.
Fill me up like you own it."
He buried himself to the balls and let go, cock throbbing as thick ropes of cum pumped straight into her. She came again just from the feeling, walls milking every drop. He stayed inside her, rocking slowly while the overflow started to seep out around his softening dick.
Later, in the bedroom, she got on all fours and spread her cheeks so he could see his cum still dripping from her used pussy. He got hard again fast, slid back in, and fucked her slow and deep this time, telling her exactly how her tight hole felt wrapped around him. She pushed back to meet every thrust, moaning about how much she loved her brother's nut inside her.
They kept going until the sheets were soaked and she was a shaking, cum-filled mess. He pulled out only to watch the thick white load ooze from her swollen pussy lips before pushing back in for one more round. No guilt, no stopping, just raw need and the same filthy words on repeat until they both collapsed, his cum still leaking out of her.
