She went down the stairs and into the family room where Karen and Billy were watching television. She stood in the doorway, one knee out. "Don't you think it's time for bed, you two?"

Karen and Billy looked at her, and Billy licked at his lips when he saw her. Karen's eyes opened, and Susan was sure there was a sparkle of excitement in them.

"Okay, mother," Karen said, turning off the television. "Come on, Billy. Time for bed…like mother said."

Susan walked ahead of her children, feeling their eyes on her exposed ass. She could not help but wiggle a bit for them. She heard a soft giggle from one of them, and a flush of excitement bubbled through her body, tingling and hotly.

Susan entered her own bedroom as the children went to theirs. She remained in her room for half an hour, waiting for Billy to come to her. But after a while she could wait no longer. She went into the hallway and toward his room. She found him in his bed, the sheets kicked to the floor. He was naked, his cock hard. His fist pumped on it.

"Why didn't you come to me, darling?" she asked, stepping close to his bed. "I waited."

"What about Karen?" he questioned.

Susan reached down and fondled her son's balls as he continued to stroke his cock. "1 have a feeling…"she said, then paused. "I have this strange feeling she already knows what we're doing."

She sat on the side of her son's bed, tugging and squeezing gently at his balls, her eyes burning down as she watched him stroking his cock. "I love to see you playing with your cock, baby," she whispered.

He arched his hips up, squeezing his cock hard. "Don't hurt it, Billy," she warned.

"That don't hurt, Morn," he replied. "It feels good when I squeeze it."

"Don't come, though. When you come, I want it in me."

She stretched out at his side, thrusting her tongue into his eager mouth. Billy sucked at her tongue hungrily. When she pulled away, she smiled down at him. "You're learning fast for a kid your age, you horny little shit."
