The sound of the sliding glass doors in the dining room startled her. Susan quickly pulled her pussy from her son's cock, stuffed it into his pants and pulled her shorts closed. By the time Karen entered the kitchen, both she and Billy were proper, although each still breathed a little fast. Susan's face was flushed with the glow of her come, and both she and Billy had shining eyes.

Karen looked at them, her eyes questioning. Susan kept her expression clear, hoping it wouldn't show. Billy had a flush on his face, and glanced at his sister from the corners of his eyes. When he glanced at his mother, neither of them could hold back the wicked grin.

Susan was certain her daughter suspected something. It seemed to show in her young eyes when she looked at her or her brother. She considered for a moment if it really mattered if Karen knew, if her daughter thought badly of her. Then she decided it did not matter to her at all if Karen felt she and Billy were involved sexually.

Throughout the rest of the day, her children remained at home, in the house. Her son's eyes followed her wherever she was, what she was doing. Now and then she caught Karen glance at her brother. It was early afternoon when she realized she hadn't rebuttoned her shorts all the way, and that her thighs flashed all the way to her hip as she moved about the house, dusting, cleaning. Once she realized it, she did nothing about it. Being seen was a thrill to her, and she found it exciting to know that both her son and daughter kept watching her thighs and hip.

That evening, when it was time for bed, Susan showered as usual, putting on a clinging gown. The gown was almost transparent, and her nipples could clearly be seen. The thick patch of dark cunt hair was shadowed, too, and she knew very well the curvy cheeks of her ass could be seen.
