The house was empty except for the three of us that night, but it was really just me and my sister Lisa who mattered. Mom and Dad were out of town, and our older brother Jake had come home from college for the weekend. We were all adults now, but the old family rules about keeping distance never applied once the lights went down and the booze came out.
Lisa was twenty-two, built like a wet dream with heavy tits that strained every shirt she wore and an ass that begged to be grabbed. Jake was twenty-four, tall and thick with muscle, and I was twenty-one, already hard just from watching her bend over the fridge for another beer. The air got thick fast. We started with shots, then Lisa dared us to play truth or dare like we were kids again, only this time the truths were nasty.
"Truth," Jake said, eyes locked on her chest. "Have you ever thought about fucking family?"
Lisa laughed, low and dirty. "Every fucking day. Especially you two. I finger myself thinking about my brothers' cocks."
That broke the dam. Jake pulled her onto his lap right there on the couch. His hands went straight under her shirt, squeezing those big tits while she ground her ass on his bulge. I watched, stroking myself through my jeans, until she looked at me and said, "Get over here and help, little brother."
I dropped to my knees in front of them. Jake yanked her shorts down, exposing her shaved pussy already glistening. I buried my face between her legs and licked like a starving man, tongue fucking her hole while Jake fed her his thick cock. She moaned around it, sucking sloppy and loud, spit running down her chin onto her tits.
"Fuck, your sister's cunt tastes so good," I growled, two fingers pumping into her while my tongue circled her clit. Lisa came hard, thighs clamping my head, her juices flooding my mouth.
Jake flipped her onto all fours. He slammed into her from behind, balls slapping her ass with every thrust. "Take it, you filthy incest slut. Been wanting this family pussy for years." She pushed back, screaming for more, telling him to wreck her.
I stood and shoved my cock into her open mouth. We spit-roasted her right there in the living room, the same couch where we used to watch movies as kids. Her throat squeezed me while Jake pounded her dripping cunt. The wet sounds of skin on skin and her gagging filled the room.
We switched. I took her pussy next, sliding into that tight, soaked heat. Jake fed her his cock fresh from her own cunt, making her taste herself. "Suck your brother's dick clean," he ordered. She did, moaning around it. I fucked her hard, slapping her ass red, watching her tits swing.
We moved to the kitchen table for more room. Lisa on her back, legs spread wide. Jake ate her out while I sucked her nipples, biting them until she begged. Then he stood and drove into her again. I straddled her face so she could lick my balls while I jerked off over her.
"Both of you," she panted. "I want both my brothers' cum."
We gave it to her. Jake pulled out and painted her tits and stomach.

I came down her throat, watching her swallow every drop. She rubbed the mess into her skin like lotion, then licked her fingers clean.
We weren't done. We fucked all night, moving from room to room. In Mom and Dad's bed, Lisa rode Jake reverse cowgirl while I took her ass for the first time, stretching her tight hole with slow, deep strokes until she was screaming and coming again. We double-teamed her on the floor, one cock in her pussy, one in her mouth, then switched holes until she was a shaking, cum-drunk mess.
By morning we were all sore and sticky, but grinning. Lisa kissed us both and said, "This is our new family tradition."
We kept it going every time the house was empty after that. Raw, nasty, no limits. Just three adults who knew exactly what they wanted from each other.
