The house was quiet except for the low hum of the old TV in the basement. Jake sat on the couch, remote in hand, scrolling through the hidden folder on his dad's external drive. He knew he shouldn't, but the label "Family Tapes" had pulled him in like a magnet. The first video started with his sister Emily, eighteen and fresh out of high school, lying on her bed in nothing but a thin tank top and panties. She was talking to the camera like she was alone, legs spread, fingers already rubbing her pussy through the cotton.
"Fuck, this is hot," Jake muttered, his cock hardening fast. He unzipped and pulled it out, stroking slow as the video cut to her pulling the panties aside and sliding two fingers deep inside herself. Her moans filled the room, wet sounds coming through the speakers. Then the door opened on screen and their older brother Mike walked in.

No hesitation. Mike dropped his pants, climbed onto the bed, and shoved his thick cock straight into Emily's mouth while she kept fingering herself.
Jake's hand moved faster. On screen, Mike pulled out and flipped Emily onto her stomach, yanking her hips up. He slammed into her from behind without warning, the slap of skin loud and filthy. "Take it, sis," Mike growled, pounding her hard. Emily pushed back, begging for more. "Fuck your little sister deeper. Fill that cunt."
Jake paused the video, breathing heavy. He had to see if there were more. The next file was their mom, Linda, on her knees in the kitchen, sucking Mike's cock while Emily filmed. Linda's tits bounced as she gagged on it, spit running down her chin. "That's it, baby, fuck Mommy's throat," she said between sucks. Then Emily joined in, the two of them licking Mike's shaft together, tongues meeting at the head.
His own cock throbbed painfully now. Jake stood and headed upstairs. Emily's door was cracked. He pushed it open. She was on her bed, phone in one hand, the other between her legs, watching the exact same video. "Couldn't wait either, huh?" she said without looking up, voice thick.
Jake walked in and shut the door. "You knew I would find them."
Emily pulled her fingers out and licked them clean. "Dad left the drive out on purpose last week. Figured you'd join the fun." She spread her legs wider. "Come here and fuck me like Mike does."
No more talking. Jake stripped, climbed on the bed, and buried his face between her thighs first, tongue lapping at her soaked pussy. She tasted sweet and dirty, already dripping. Emily grabbed his hair and ground against his mouth. "Eat it. Get it ready for your cock."
He flipped her over, yanked her ass up, and drove into her in one thrust, just like in the video. Her walls clenched tight around him. "Goddamn, you're wet," he grunted, thrusting hard and fast. Skin slapped. Emily moaned loud, pushing back to take every inch. "Harder, brother. Wreck my cunt like you mean it."
They fucked raw and rough, changing positions without pause. Jake on his back while she rode him, tits bouncing, then her on all fours again so he could spank her ass red while pounding deep. She came first, pussy pulsing and flooding his cock with juice. He didn't stop, kept slamming until he pulled out and shot thick ropes across her ass and lower back.
They lay there catching breath, the video still playing on her phone. "There's more," Emily said, smiling. "Mom's waiting downstairs. She wants both of us on camera tonight."
Jake's cock twitched again at the thought. He grabbed her hand and they headed down, ready to make their own tape to add to the collection. The night was just starting, and every filthy family secret was about to get recorded.
