As Karen started out the sliding doors to the back yard, she looked over her shoulder at her mother, that impish, somehow-knowing grin was flashed. Then, with a twist of her sweetlittle ass, she went out.

The gesture was inviting, Susan thought.Her daughter didn't look like a sexy kid playing games, teasing, but it was exciting as hell to Susan. There was a powerful, delicious twitch in her cunt, strong enough to make her shiver. She hugged herself tightly.

The front door banged and she turned to see Billy entering the kitchen. "Hi, Mom," he said happily. "Can I have something to eat?"

Susan reached for her son, pulling him close, his face against her arching tits. "You can have any damned thing you want, baby," she teased, grinding her cunt against his stomach. "Anything at all."

She felt his hands clutching at the twin cheeks of her ass, and she mewled with pleasure. The shorts Susan wore buttoned up the side all the way to her waist. She unbuttoned them to her hip, pressing her naked thigh hard against him. She glanced out the window and saw her daughter sitting on the lawn, reading.

Fumbling with the zipper of her son's pants, she opened his fly. Reaching inside, she took his hard cock and pulled it out.

"Oh, baby!" she whimpered, tightening her fist about Billy's prick. "You're so hard, so fucking hard!"

Billy began to nibble at one of her rigid nipplesthrough her halter, soaking the thin fabric. With her other hand, she held the back of his head tightly, forcing her nipple into his mouth, sighing in pleasure. She pumped on his cock slowly, thrilled to have it throbbing against her fingers. She pressed her naked thigh to him, feeling the moisture smearing, burning against her flesh.

"Hold my ass, Billy!" she gurgled, writhing her ass cheeks into his clutching hands. "Oh, it feels so good to have your hands on my ass! Feel my ass, baby! Play with mother's ass!"
