Cindy lay back on the bed, and her brother helped her pull her pants and panties down her slim legs. For several moments, he just stared down at the little girl's cunt mound. It was completely smooth and bare, for no hair had yet begun to grow on it. The thin cunt labes were a delicate, shell-pink color, and her cunt was hidden.

Billy reached out to smooth his hand over her pretty pussy. But as soon as his fingers grazed Cindy's flesh, Cindy sat up with a start.

"Hey, what are you doing?"

"Just relax."

Now he ran his hand up to her belly and back down over her cunt mound, and she smiled with pleasure. Seeing that she liked this, he repeated the motion over and over until she was purring like a kitten.

"That feels nice," Cindy sighed, lying back on the bed. She reined her thighs a little, parting them so Billy could see the soft pink meat of her cunt.

Sally held her breath. Her cunt was churning wildly, and it was all she could do to keep from joining in the sex play. She had to satisfy herself by diddling her itchy clit through her pants.

As Billy continued to fondle Cindy's cunt mound, he grew bolder, prying apart her cunt lips so he could see more of her hard, pea-sized clit. Then he raised his forefinger to his mouth, spat saliva on it and lowered it to the vibrating nub.

"Ungh!" Cindy groaned, raising her thighs and knocking her knees together.

Billy smiled wickedly. "Come on, Cindy. Just relax."

He pressed down again, this time rubbing her clit with a circular motion.

"Oh, oh, oh!" Cindy groaned, rocking from one slim ass bun to the other. "That feels good, Billy!"

"Told ya!" He kept diddling her clit, now and then letting his finger stray to her tiny cunt hole. "You're getting wet down there," he said, licking his lips and pressing his pulsing cock against the side of the bed.
