"Well… sure, shake our ass." Again, impulsively, Becky began to shake her ass, her linen skirt swirling about her slender thighs.

"Hey, that's kinda cute, Mom," Ted said.

"Oh, yeah!" Becky giggled like a little girl. "You think that's cute, watch this!"

She turned her back to him, arching her ass, and swung it around in a perfect gyration, then humped it toward her son.

"Nice, Mom," Ted said. Then he slapped her ass.

"Ouch!" Becky gasped, grabbing her ass with both hands and rubbing, pretending it had hurt. "That hurt."

"Well, a guy has to grab when he has the chance, doesn't he?"

"Oh, so that's the way it is, huh?" she said, grinning impishly at him. "Steal a quick feel when a girl isn't looking, right?"

"You got it, Mom," her son replied, giggling with her. "That felt pretty good. You've sure got a pretty ass on you, Mom."

"Oh, is that right?" she asked, feeling herself trembling slightly. "What's so pretty about it?"

"It's round and tight and… you know, cute, the way an ass is supposed to be cute."

"You're sure about that?" Becky asked, her green eyes, taking on a smoldering expression. Something was happening inside her, something that felt warm, and she felt her cunt flexing, her cunt suddenly swelling into a hardness.

"I've seen it, Mom. So I know it's cute."

"Ted, you have not!"

"Have, too!"

"When?"

"I better not tell," he said, suddenly shy. "I don't wanna get into any trouble."

He looked down at the floor as he shuffled a foot around.

Becky stared at her son, not knowing why she was feeling so excited all of a sudden. The urge to pull him against her body, press his face against her tits, to stroke and caress his ass, maybe feel his cock and balls, was suddenly a powerful desire inside her.

"Why would you get into trouble?" Becky's voice trembled, and her eyes seemed to be trying to focus on the front of his jeans.
