Bobby left the fray, sitting back and watching, his eyes hot. He saw his sister make a playful grab for their mother's crotch and as Lynn scrambled to get away, her dress went almost to her tits. He saw the dark curls of her cunt hair swirling beneath her panties. His cock was throbbing.

"I thought I heard someone here," a man said.

Carolyn jumped to her knees. Lynn gasped, trying to shove her skirt down as Jake came out of the brush grinning. Lynn looked at the man, her face feeling very warm. She knew he had seen them wrestling, seen her flimsy panties.

He squatted on the edge of the blanket. Lynn's eyes dropped between his knees to the lump of his cock and she swallowed nervously.

"I'm always running people off," he said easily. "If they'd clean up after their picnics it wouldn't be bad, but I've always got to pick up their trash."

Carolyn saw the way her mother was looking. The girl stood up and motioned to her brother and they slipped away quietly. But the teenagers didn't go far. They concealed themselves in thick bushes near-by, turning to watch.

"I knew you were there last night, Miss Lynn," Jake said bluntly.

Lynn felt a shudder go through her and she stared at Jake.

"I guess you got a little excited," Jake went on. "I saw you sitting outside, Miss Lynn. And I heard you breathing and watched you go back into your house."

Lynn felt mesmerized by him. When he pulled her into his arms, she didn't resist. His mouth came down onto hers in a burning kiss.

In the bushes, Bobby stifled a giggle. Carolyn poked him, shushing him.

"I wanna see it," Bobby giggled. "I bet Mom is gonna get fucked!"

"I hope so," Carolyn murmured, opening her brother's pants and taking his cock out.

They watched their mother and Jake as Carolyn jacked on Bobby's cock. Kissing Lynn, Jake ran his hand up her thighs, shoving her dress up. Lynn moaned into his mouth as his fingers stroked the wet crotch of her panties.
