"I wanna touch," Cindy said.

Kathy watched the girl lift her skirt to her waist, and for the first time saw that Cindy was not wearing panties. Cindy spread her legs wide and over her brother's thighs. Kathy saw Cindy's cunt was framed by scant blonde hairs. Her pink pussy seemed to glow, and the tip of Cindy's tiny clitoris poked out.

Cindy pulled her brother's cock to her cunt and rubbed it about her cunt. Kathy felt her own cunt twitching with desire again as she watched the head of Robert's swollen cock moving up and down his sister's sparsely haired cunt. Excitement gripped her again, and she began breathing harshly, her naked tits jiggling tightly.

"Oh, I like the way your cock feels against my cunt, Robert!" Cindy gurgled in a soft voice. "Can you feel how hot my pussy is, Robert?"

"It's hot, all right," he said, watching as Cindy rubbed the head of his dripping cock up and down the pink, sugary lips of her twat. "It's always hot, though."

Kathy knew now that this was not the first time brother and sister had played their sex games. They must be fucking like wild sex maniacs, Kathy thought. Somehow that made her even more excited.

She watched Cindy shove her brother onto his back, his cock standing up in the air, throbbing and jerking about. Then Cindy squatted over her brother, holding her fringed skirt about her small waist. Kathy stared at Cindy's compact ass cheeks. Cindy had the sweetest, prettiest ass Kathy had ever seen.

Cindy's ass swelled out beautifully, the cheeks rounded and springy, very smooth and without a blemish. Her legs were quite long and slender. As Cindy squatted above her brother's cock, Kathy could see the cheeks of her sweet little ass spread, and the pucker of Cindy's asshole was revealed.
