"But I'm sure Susan is home with you," Marcy said.

"She is," Jerry replied. "Susan is awfully nice, Mother. If I have to have a stepmother, I'm glad it's Susan."

"I guess you and she…" Marcy's mind drew up erotic pictures. "I mean, she takes you places when your father isn't there, don't she?"

"Oh, yes," Jerry said. "We went to the zoo and next weekend she's gonna take me to the amusement park."

"That will be fun, I'm sure," Marcy said.

"Go with us, Mother," Jerry said suddenly. "It would be more fun if you went with us. Come on, please! Dad won't be there. He's already said he had to go out of town. Came to the amusement park with me and Susan, Mother, please!"

"I'll think about it, honey," she said. "We have to see what Susan thinks about that. Remember, she's your stepmother, and may not want me with you."

"She will," Jerry said in a rising voice. "She talked about you all weekend. Susan likes you, Mother! I know she likes you."

Marcy thought she could feel Susan's hand between her legs again, pushing at her cunt the way it had a few days ago. She had thought about that all weekend. She had never in her entire life reacted to such stimulation with so much heat and hunger.

"I like your stepmother, too, baby," she said softly, and pulled her son against her tits, hugging him. "I'm glad you like her, and I'm very glad she loves you as much as I do!"

Jerry twisted and squirmed until he was lying on her bed, pressing his young body tightly to her. He wrapped his arm about his mother's waist, resting his head on her shoulder as she held him. Marcy caressed him, running her hand into the neck of his robe to stroke his smooth back. It felt good to be held by her son this way, felt good to feel him lying close to her. She purred in delight when he squeezed her waist. And then her eyes widened.

She felt her son pushing his hips against her. She was covered only by the thin sheet, and she felt his hardness on her hip.
