Hank pushed brutally forward, fucking her mouth with almost half of his cock. Then his balls exploded. The white tide of gooey jism rushed up from his ball sac, making his cock quiver as the first jet sprayed from the tip of his prick.

"Ummmm…" Marie whimpered hungrily as she gulped down the initial blast of cock juice. It was delicious, even better tasting than she'd hoped. Her cunt throbbed and burned, as she relished the creamy, sappy thickness of his salty cum.

His prick kept on squirting, blasting geysers of cock milk down her throat. Marie had read about men venting loads of cum into a woman's sucking mouth, but nothing had prepared her for the load of her brother's cock juice.

Again and again she swallowed, frantically working her throat muscles, but she couldn't take it all down. The sticky jism bubbled out of her mouth, running obscenely down her chin and dripping onto her tits.

"Augh! Take it out! Can't take anymore!" Hank winced, trying to push her away. "Oh Christ, you suck like a vacuum cleaner!"

Marie whimpered with frustration, trying to keep his throbbing cock in her mouth. She wanted to suck down more of the sticky stuff. But Hank pushed her roughly away, and she licked her lips as she stared shamelessly at the big wet cock throbbing in front of her face.

"Did I do good, big brother?" she asked eagerly.

Hank gulped and nodded his head. He was staring at her body now, she realized, focusing hornily on her sleek, slim legs and her hairy pussy. His cock seemed to wilt slightly for a moment, then popped right up again, quivering before him as if he'd never cum at all.

"Mmm, you've still got a big boner," she whispered huskily. Giggling, the horny little girl leaned back, squirming her ass on the bed and splaying her legs wide apart. "Look at my pussy, Hank. Isn't it nice and juicy looking? Don't you want to fuck me?"

Hank moaned at the sight of his sister's tight pussy, wondering about the wrongness of giving his own sister a good fuck. But a stiff cock had no conscience, particularly when it belonged to a horny stud.
