"Suck it! Suck my cock! I'm gonna shoot!" Brad groaned just a few seconds later.

He felt the surge of cum racing from his nuts, up the long shaft of his cock. Franny opened her mouth wide and lowered her head more, burying her face in his crotch. She hungrily took his load down her throat as she gripped her nips, pinching them mercilessly. Little jolts of pain and pleasure shot through her and her pussy drooled with juice as she drank down every drop of her brother's cum.

Brad humped and bucked on the car seat, driving his ass upward and sending his thick cock delving into the depths of Franny's hot, hungry mouth. He was fucking his little sister in the face. And she was slurping up his hot, creamy jism as fast as he could shoot it from his pulsing prick.

"God, that's soooo fuckin' good!" he grunted.

Franny licked up every drop of her brother's hot cum as it spilled out of his piss-slit. She sucked him dry and finally Brad fell back against the car seat, drained.

Franny licked her lips, savoring the taste of the boy's creamy cum on her lips and tongue.

"Come on, Franny, you just gave me a great blowjob. Won't you let me fuck you now?" Brad pleaded, his cock already growing hard again with the thought of fucking his little sister.

"No!" Franny cried, opening the car door and climbing out.

"You cock-teasing bitch!" Brad cursed, shoving his cock back inside his pants. He zipped himself up and cast a scornful glance in his sister's direction.

"What are you waiting for? Go on! Run into the house like the scared little virgin that you are!"

But Franny just smiled sweetly at her brother. She closed the car door and leaned her head in the open window.

"Goodnight, brother, dear. Thanks for the delicious late-night snack," she whispered. Then, with a little laugh, she turned and walked into the house.
