The answer was given to her when Becky moved her hand slowly down the back of her uplifted thigh. Julie didn't gasp, but her breathing increased as her eyes followed the small finger. Becky's eyes twinkled brighter as she ran the tip of her finger along the exposed leg of her panties.

"All right," Julie finally said, her voice throaty. "What's going on here, kids?"

Becky released her pent-up giggles, her finger touching the band of her sunsuit, near the crotch. Ben acted nervous, but he was still trying to get a glimpse of his mother's crotch. His cock, Julie saw, was pressing at his shorts, fully hard now.

It was Becky who answered.

"You put Ben's peter in your mouth, Mother," she said, giggling.

"Peter?" Julie asked, unable to stop grinning at the word. She had not heard that particular word in ages.

"You know, Mother," Becky giggled again. "His prick!"

Julie felt as if she should blush, but she didn't.

"I did?" she asked, smiling.

"I wasn't dreaming, Mom," Ben said, with just the faintest flush on his young face.

Julie thought quickly. There was no way she could deny it.

"So what if I did?" she asked, her voice low. She felt the wetness between her thighs, her cunt quivering.

"But you let him do it in your mouth, Mother," Becky said. "You let Ben do it in your mouth!"

Julie looked at them before she replied. "So I did. But what did I let Ben do in my mouth?"

Becky giggled.

Ben stared at his mother, eyes big. "Come on," Julie urged; "Let's get it out in the open, kids. Stop pussy-footing around and say it like it is."
