He felt a fresh rush of blood course through his cock as his little sister continued to suck it.

God, I wish she'd let me fuck her! Brad cursed to himself as his sister continued to give him one of her most expert blowjobs. She's one hell of a cocksucker and she really loves cock, but why is she holding out on me? How I'd love to pop her tight little cherry for her!

Franny moaned excitedly as she sucked harder and harder on her big brother's hard, tasty cock. At the same time, she was making herself as hot as possible by continuing to squeeze her tits with her free hand. She gobbled hungrily on Brad's cock, taking long swipes on it with her tongue and sucking for all she was worth.

Franny squirmed and wriggled on the floor of the car while she pinched her nipples, twisting them in her fingers and sucking on her brother's throbbing prick at the same time.

"Jeeesus!" Brad groaned.

He felt his nuts tightening up. They were filling with hot cum and he knew that soon he would have a load to let go into his sister's thirsty mouth. "Oh yeah, baby. Take my cock! Take it all, you cocksucking bitch!"

With one hand, Franny gripped her brother's prickshaft. She slid her hot wet tongue downward, and Brad's hips jerked when he felt one of his balls being sucked into her mouth. She rolled her tongue around and around his hard ball. She sucked and licked at the soft skin of his ball sac as she pulled her hand up and down on his saliva-slickened cockmeat.

"Ohhh, yeah!" Brad cried. He loved the feet of his sister's velvety tongue lapping at his nuts.

Franny licked first one ball, then the other. Then she licked them both, swirling her tongue all over their firm, throbbing surface. The young virgin was really working at giving her brother as much pleasure as possible. She was sucking and licking his balls and cock, and continuing to play with her tits as she drove the boy closer and closer to orgasm.
