Cindy knew that most of the kids at school were constantly balling each other, but this was the first time she'd ever seen two people performing this lewd act. The thing that amazed her the most was that Julie's little twat could take such a big swollen cock. Until now, little Cindy had always assumed that a man's prick was probably about the size of a finger, so she was completely stunned by the size of her uncle's cock. She was equally amazed at the size of the lust bloated balls that were slapping against Julie's ass.

"Oh, shit, Daddy!" she heard her writhing cousin squeal with joy. "Oh, Christ, how I love to feel that beautiful big cock fucking my cunt!"

"Then hang on, darling!" panted the man. "I'm gonna give you the biggest hottest load you've ever had!"

"Yes! Yes!" whimpered Julie. "Just give me everything you've got!"

Their dirty language and passion-crazed voices were arousing little Cindy as she watched, but she still couldn't understand how a father could enjoy fucking his own kid. It was a depraved thing to watch, but seeing the look of wanton ecstasy on Julie's face, Cindy began wondering how a hard prick would feel in her own little twat. She decided it must feel pretty fantastic.

"Oh, sweet humpin' Jesus!" Julie was screaming, arching her loins up to meet every thrust of her father's wildly plunging dick. "It feels so fuckin'… fuckin' good, Daddy!"

Cindy began rubbing her own aroused pussy through the material of her jeans. Wanting to stimulate herself even further, the youngster lowered her zipper and wormed her finger through the leg of her panties. She drilled it into the hot slickness of her juicy slit. Excitedly watching the father and daughter writhing around on the bed, Cindy began vigorously massaging her suddenly erect clitoris.
