Jake slammed the door behind him and found his sister Emily already in the kitchen, bent over the counter in nothing but a thin tank top and panties. She was 22, he was 24, and they had the house to themselves for the weekend. "You know what the fuck this is," he said, voice low and rough. Emily turned, nipples hard through the fabric, and smiled dirty. "Been waiting for you to stop pretending you don't want to fuck your own sister."
He grabbed her by the hips and spun her around, yanking the tank top up and over her head. Her tits spilled out, full and heavy. Jake sucked one nipple hard, biting just enough to make her gasp. "This pussy better be wet already," he muttered, shoving his hand down her panties. Two fingers slid straight into her slick cunt. Emily moaned and pushed back against his hand. "Always wet for my brother's cock. Been thinking about it all week."
Jake ripped the panties down her legs and bent her over the counter again. He freed his thick dick, already leaking, and rubbed the head up and down her slit. "Beg for it," he ordered. "Tell me you want your brother to fuck you raw." Emily spread her legs wider. "Fuck me, Jake. Shove that cock in your sister's cunt right now."
He thrust in deep on the first stroke, burying himself to the balls. Emily cried out, gripping the counter edge. Jake started pounding immediately, hard and fast, skin slapping loud in the quiet kitchen. Her pussy gripped him tight, hot and dripping. "Goddamn, this incest pussy feels so fucking good," he growled, reaching around to rub her clit in rough circles. Emily pushed back to meet every thrust. "Deeper. Fuck your sister deeper. Fill me up."
They moved to the couch without pulling out. Jake sat down and pulled her onto his lap, facing away. Emily rode him reverse, bouncing hard on his cock while he slapped her ass and watched it jiggle. "Look at you, slutty little sister taking every inch," he said, gripping her hips and slamming her down. Her juices ran down his shaft and balls. She reached between her legs to play with his heavy sack. "Gonna come on my brother's dick," she panted. "Don't stop."
Jake flipped her onto her back on the cushions and hooked her legs over his shoulders. He fucked her deep and brutal, the new angle hitting her spot with every stroke. Emily's tits bounced with the force. "I'm close," she warned. Jake leaned down, mouth by her ear. "Come on my cock while I fuck you. Do it." She came hard, cunt pulsing and squeezing, soaking him even more. Jake didn't slow down, just kept driving through her orgasm until she was shaking.
He pulled out, flipped her onto her stomach, and mounted her from behind again, this time pushing her thighs together so her pussy felt even tighter. "Gonna fill this cunt," he grunted, pace turning frantic. Emily reached back and spread her ass cheeks for him.
"Do it. Breed your sister's pussy. Give me every drop." Jake buried himself to the hilt and came, cock throbbing as he pumped thick ropes of cum deep inside her. He stayed buried, grinding through the aftershocks while Emily milked him with little clenches.
They stayed like that for a minute, breathing hard, his cum already starting to leak out around his softening dick. Jake pulled out slow and watched it drip. Emily rolled over, spread her legs, and scooped some onto her fingers, licking them clean. "Round two in the shower," she said. "Then you can fuck my ass if you want." Jake grinned and hauled her up. "Incest weekends are the best fucking weekends."
