Bobby's cock thrust against his pants and Carolyn placed her hand on it, rubbing. Carolyn saw the gleam in her brother's eyes and she leaned to his ear.

"You want to fuck her, Bobby?" she whispered. "Wouldn't you like to stick your cock in Mother's cunt? I bet you'd love to feel her hairy cunt on your prick, wouldn't you? You know it was Mother who sucked you off last night. Yes, it was Mother who gave you that blow-job."

"Quiet it, Carolyn," he hissed at her.

Carolyn was wearing a sun-suit made out of a stretchy material and she slipped a finger into the crotch, pulling it to one side.

"Look at this," she whispered lewdly into his ear. "This is a hot cunt too, Bobby. Would you like to fuck this cunt again?"

Lynn heard their whispering and peeked at them through slitted eyes. She saw her daughter pulling the crotch of her sun-suit wide, showing the hairiness of her young cunt. She saw, too, her son's cock harder with Carolyn caressing it. Lynn's foot moved, the light sound startling Carolyn. The girl quickly pulled the crotch of her sun-suit back and jerked her hand off her brother's cock.

"Let's eat," Carolyn said nervously. She knew her mother had seen what she was doing.

Suddenly Bobby grabbed his sister and shoved her over, climbing up on top of her and trying to pin her arms.

"Stop it, Bobby!" Carolyn squealed.

But he refused to stop. Carolyn began wrestling with him, squealing with pleasure. They rolled and thrashed about, twisting into Lynn. She started to get up but Carolyn grabbed her, pulling her into the wrestling match. Lynn began to laugh with them, both her son and daughter turning on her. They tickled her, making her shriek with laughter and kick her legs wildly. Her skirt hiked about her waist, her long legs and pantied hips exposed. Lynn gasped when her daughter poked at her cunt playfully.
