The house was quiet except for the wet sounds coming from the living room. Mom was on her knees between Dad's legs, sucking his cock like she was starving for it, her big tits swinging as she bobbed her head fast and sloppy. Spit ran down her chin onto her heavy breasts while she gagged herself deeper every time.
"Take it all, you filthy slut," Dad growled, grabbing her hair and fucking her throat. Mom moaned around his shaft, her hand between her own thighs rubbing her dripping cunt.
I stood in the doorway watching, my own dick rock hard in my jeans. My sister Lisa pressed against my back, her hand already down my pants stroking me slow and tight. "Fuck, they're really going at it tonight," she whispered, biting my ear. "You gonna join or just stand there like a pussy?"
I turned and shoved her against the wall, yanking her tank top down so her perky tits popped out. I sucked one nipple hard while I shoved two fingers straight into her shaved pussy. She was soaked. "You're next, little sis," I said, pumping my fingers deep until she was grinding on my hand.
Mom looked up and saw us. She pulled off Dad's cock with a wet pop and smiled, lips shiny with spit. "Come here, both of you. Family time."
Lisa dropped to her knees next to Mom and took over sucking Dad while Mom crawled over to me. She unbuttoned my jeans and pulled my cock out, licking the head in one long stroke before swallowing me whole. Her throat was hot and tight. She sucked like she wanted to drain me dry, one hand cupping my balls while the other reached back to finger her own ass.
Dad had Lisa bent over the couch now, pounding her from behind. The slap of his hips against her ass filled the room. "That's it, fuck your sister good," Mom said around my cock, then stood up and pushed me down on the floor. She straddled me and sank down on my dick in one smooth motion, her cunt gripping me like a fist.
She rode me hard, tits bouncing, while Dad switched to fucking Lisa's mouth. Lisa gagged and drooled all over his balls, eyes watering but pushing back for more. Mom leaned forward so I could suck her nipples, then reached back and spread her ass cheeks. "Finger my asshole while you fuck me," she ordered.
I did, sliding a finger into her tight ring while my cock stretched her pussy. She came hard, shaking and cursing, her juices running down my balls.
Dad pulled out of Lisa's mouth and flipped her onto her back on the coffee table. He spread her legs wide and slammed back into her cunt. Lisa screamed and grabbed her own tits, pinching her nipples while he fucked her like a machine. "Harder, Daddy! Wreck my pussy!"
Mom climbed off me and pushed Lisa's face between her legs. "Eat Mommy's cunt while Daddy fucks you." Lisa did, tongue working fast on Mom's clit while Dad kept pounding her.
I moved behind Dad and lined my cock up with his ass. He didn't stop fucking Lisa. He just pushed back and let me sink into his tight hole. I fucked him slow at first, then harder, matching his rhythm so every thrust drove him deeper into my sister.
Mom came again on Lisa's tongue, then pulled me out of Dad and onto the couch. She sat on my lap facing away and took my cock in her ass this time, riding reverse while she watched Dad and Lisa. "Look at your sister getting railed," she panted. "She's such a whore for family cock."
Lisa was on all fours now, Dad behind her and me in front feeding her my dick. She sucked me while Dad fucked her ass, the three of us moving together until Dad groaned and flooded her guts with cum. It leaked out around his cock as he kept thrusting.
Mom pulled Lisa over and made her sit on my face while she sucked my cock clean. I ate my sister's cum-filled ass and pussy while Mom deepthroated me. Lisa came on my tongue, shaking and grinding down.
Dad recovered fast. He pulled Mom onto the floor and mounted her from behind, fucking her ass while I slid under Mom and into her pussy. We double-teamed her, cocks rubbing together inside her with only a thin wall between them. Mom screamed and came again, her holes clenching tight.
Lisa straddled Dad's face so he could eat her while we kept fucking Mom. The room smelled like sex and sweat. Everyone was slick and loud.
We switched again. Lisa on her back with Mom sitting on her face, Dad fucking Lisa's pussy, and me in Mom's ass from behind. Mom reached down and rubbed Lisa's clit while she got pounded. Lisa came so hard she squirted around Dad's cock.
Finally Dad pulled out and shot thick ropes across Lisa's tits and stomach. Mom licked it up and snowballed it into Lisa's mouth. I kept fucking Mom's ass until I pulled out and painted her back with my load.
We collapsed together on the floor, bodies tangled, cum and sweat everywhere. Mom kissed me slow and deep, then turned and kissed Lisa the same way. Dad just laughed low and pulled both women against his chest.
"Same time tomorrow?" Lisa asked, already stroking my half-hard cock again.
Mom smiled, licking cum off her fingers. "Every night, baby. We're family."
