We were all home for the weekend and the booze flowed fast. My sister Lisa, 22, bent over the kitchen counter first, her ass up and pussy dripping. "Come on, bro, fuck me while Mom watches," she said, looking straight at me. I dropped my pants and slammed my cock into her tight cunt, pounding hard and deep while our parents sat on the couch stroking each other.
Dad grunted and told Mom to get naked. She stripped slow, tits heavy and nipples hard, then dropped to her knees and took Dad's thick dick in her mouth. Lisa moaned louder, pushing back on my thrusts. "Harder, fuck your sister harder." I grabbed her hips and rammed in balls-deep, skin slapping loud.
Mom pulled off Dad and crawled over. "My turn with my son." She spread her legs on the floor and I pulled out of Lisa to bury my face in Mom's wet pussy, tongue-fucking her while Dad moved behind Lisa and started fucking her doggy-style. Lisa screamed when Dad's cock stretched her.
I stood up, lined my dick up with Mom's hole, and drove in. Her cunt was hot and slick, gripping me tight. We fucked right there on the rug, Mom's legs wrapped around me, her nails digging into my back. Across the room Dad was railing Lisa, calling her a dirty little slut while he slapped her ass red.
Lisa crawled over next, pushing Mom aside so she could suck my cock clean of Mom's juices. Mom didn't miss a beat; she turned and started eating Lisa's pussy while Dad fucked her from behind. The room filled with wet sounds, moans, and filthy talk. "Suck your brother's cock, baby," Mom told Lisa. "Taste how good your pussy is on him."
We switched fast.
I fucked Mom again while Dad took turns on both girls. Lisa rode Dad's face and Mom rode his cock. Then the girls got on all fours side by side and Dad and I switched holes every few strokes, pounding whichever cunt was closest. Lisa came first, shaking and squirting on my dick. Mom followed right after, screaming into the carpet.
We didn't stop. Dad fucked Lisa's ass while I fucked Mom's. The girls kissed and fingered each other the whole time. Later we piled on the big bed upstairs. Mom on her back with Lisa sitting on her face, me fucking Mom's pussy while Dad fucked Lisa's mouth. Cum was everywhere, on tits, faces, asses. We kept going until everyone was spent and sticky, bodies tangled, breathing hard.
By morning we were at it again in the shower, soapy hands and hard cocks sliding into every hole we could reach. No one talked about stopping. This was our new normal, raw and nasty and exactly what we all wanted.
