She did not notice when Karen Mason entered the yard.

Karen was Tom's mother, a year older than Susan's thirty-two. Karen was an extremely beautiful woman, tall and slender, with deliciously shaped curves. Karen's tits arched and swelled out in perfection, and her ass was a delight to look upon. It was tight and curvy, and flexed when she walked. Karen was as sensual as Susan, if not more so. She knew she was attractive, and dressed to show off her inviting body. She wore a halter over her tits, and the nipples were outlined clearly. She also wore a pair of very brief shorts, with slits up each side almost to her waist.

"My, my," Karen said quietly.

Susan opened her eyes. "Oh, hello, Karen."

"You want to know something, Susan?" Karen said, sitting in a padded chair. "You're giving those boys of ours quite a nice show."

"What do you mean?" Susan said, sipping at her beer, which had become warm.

Karen pointed a finger. Robert and Tom were sitting on the grass facing the women, their eyes wide and hot looking.

"I still don't understand," Susan said.

"Look at your skirt, honey."

Susan looked, and saw that her skirt had come almost to her hips. "Oh, God!" she cried, quickly closing her thighs and smoothing her skirt down.

"It's too late, baby," Karen laughed softly.

"They were sitting there staring at your panties. I saw it when I came through the gate. Did you know there's hair sticking out at the crotch?"

Susan's face flushed. She sat up quickly, placing her feet firmly on the patio.

Karen laughed again. "They sure got themselves an eyeful, Susan. Me too, for that matter."

"Stop it, Karen," Susan said, but she wasn't angry.

"I'm sure those two boys of ours have delicious hard-ons about now."

"Oh, Karen!" Susan sighed. "Must you always talk like that?"
