"She was awake, dummy," Carolyn said. "A girl can't get fucked while she's asleep. It wakes her up."

"Carolyn!" Peggy gasped again. "You don't talk that way!"

"Why not?" her daughter giggled. "He did fuck you, Mother. I saw him standing there and fucking you… fucking you good, and you liked it, because I heard you moaning."

Peggy didn't know how to reply. She was lost for any words. She was shaking, her hands gripping the steering wheel with white knuckles. She glanced over her shoulder again, quickly. Carolyn was starting to pull the crotch of her panties to one side, gazing at her brother's hardon again.

"Carolyn, you can't…" Peggy said.

"I can, too, Mother," her daughter said. "If you can, I can. It's only fair."

Her daughter was right, Peggy told herself. She didn't have any right to stop her daughter, none at all. If Carolyn wanted to flash her succulent little cunt to her brother, Peggy had nothing to say about it.

"Ohhh, nice!" she heard Ricky whisper.

The car was barely keeping up a decent speed now, and Peggy glanced back again. Carolyn had the crotch of her pink panties far to one side, her lovely little cunt-slit exposed. The sun hit her cunt just right, making a few golden, fuzzy hairs gleam.

"Now take your cock out, Ricky," Carolyn said.

Peggy's pulses were racing. She no longer wanted to try and stop them. What she wanted to do was stop the car, turn around and watch. She twisted about quickly, and saw her son pulling his cock from the frayed leg of his cut-offs, still staring at his sister's pink cunt. His prick throbbed with hardness, and Peggy saw his smooth cock-head shining in the ray of sun coming through the window.

"Oooooh, I wanna feel it!" she heard Carolyn moan. "I wanna play with that!"

Peggy shot another glance behind her. Carolyn was stretching her hand for her brother's cock.
