"Only an hour ago," Susan asked, arching her eyebrows. "And already you've got your hand in her panties, Tommy?"

Tommy almost blushed. Almost, but not quite. This was the boldest Susan had spoken to him.

"And you, Wanda," Susan said, facing her sister. "I'm surprised at you. I really am."

"I'm sorry," Wanda whispered, gazing down at her lap, her hands folded there. "I didn't mean to do it, Susan."

"Oh, is that right?" Susan asked, but her voice was not unkind. "If you didn't mean to, why were you?"

"Mom," Tommy said. "It wasn't Wanda's fault. I'm the one."

"The one what?"

"I started it, Mom, not Wanda."

"I suppose you put her hand on your cock," Susan said.

Tommy's eyes grew hot, and Wanda's head jerked up, her blush making her face a deep pink.

"That's right – cock," Susan said, but there was no anger in her voice. "If you're old enough to play with a girl, you're old enough to hear the word, Tommy."

Susan noticed her son's cock was still very hard, outlined against his pants. That pleased her. She looked at it openly, her own eyes growing wet with desire. Tommy made no effort to try and hide his hard-on, but sat there with his knees open, hands at his sides on the cushions. Although she had her knees clamped together, Wanda's skirt was halfway up her thighs.

"Wanda, do you mind if I talk to Tommy in private for a moment?" Susan asked.

Wanda got up and, averting her face from her older sister, disappeared down the hall. Susan watched her son, who was watching the swelling cheeks of Wanda's cute ass.

"I don't care who started it, Tommy," Susan said, lowering her eyes to her son's bulging hard-on meaningfully. "That isn't important to me. What I want to know is this; you know Wanda is my sister, your aunt. Don't you feel strange about feeling her up?"

Tommy shivered with excitement, listening to his mother talk to him as if he was a grownup, using the words boys and girls did at school. Like his mother, he had sensed the changing atmosphere between them. He wanted to feel his mother's body badly, to touch her in all those secret places. If he had gotten some sort of sign from his mother, he would have been feeling her up a long time ago.
