Sarah had just turned twenty-two when she moved back in with her mom after college. The house felt smaller now, the air thick with things unsaid. Linda, her mom, was forty-five but still had that tight body from yoga and running, big tits that strained against her tank tops and a round ass that filled out her shorts. One night after a few glasses of wine, they started talking about men, then about what they really wanted.
"Fuck, I haven't been licked right in years," Linda said, her voice low and direct, legs spread on the couch in just a thin robe.
Sarah stared, feeling her pussy get wet. "Me either, Mom. I want a woman who knows what she's doing."
Linda's eyes darkened. She stood up, let the robe fall open, showing her shaved cunt and hard nipples. "Come here, baby. Show me."
Sarah dropped to her knees right there. She pushed her face between her mom's thighs and licked straight up that wet slit, tasting her. Linda grabbed her hair. "That's it, eat Mommy's pussy. Suck on my clit."
Sarah went at it raw, tongue fucking her mom's hole, then sucking the swollen clit hard while two fingers slid inside. Linda moaned loud and filthy. "Deeper, you little slut. Fingerfuck your mother."
Linda came fast, grinding on Sarah's face, juices dripping down her chin. Then she pulled Sarah up, ripped off her clothes, and bent her over the couch. "My turn." She spread Sarah's ass and buried her tongue in her daughter's tight pussy, licking and spitting, then sliding two fingers in while her thumb rubbed the asshole.
"Fuck, Mom, that feels so good," Sarah groaned, pushing back.
Linda added a third finger, pounding her daughter's cunt while she licked her asshole. "You like Mommy eating your dirty little holes? Tell me."
"Yes, fuck yes, make me come."
Sarah came hard, squirting a little on Linda's tongue. They didn't stop. Linda dragged her to the bedroom, strapped on a thick dildo, and fucked her daughter from behind, slapping her ass and calling her names while Sarah begged for more.

They switched, Sarah riding her mom's face while they sixty-nined, both coming again and again until the sheets were soaked.
By morning they were still at it, slow and nasty in the shower, fingers and tongues everywhere, promising this was just the start of their secret filthy fun.
