A grin spread over Tracy's face. She stepped up to her mother and leaned down, kissing her on the mouth. She had not kissed her mother on the mouth for years.

Feeling her daughter's moist, hot lips against hers, Susan moaned softly, and as she felt the tip of Tracy's tongue across her lips, her hand moved. Before she could stop it she had curled her fingers about Tracy's tit.

Tracy squealed softly against her mother's mouth when she felt the woman's hand squeeze her tit. Thrusting her tongue past her mother's lips suddenly, she also placed her palm upon one spongy tit. Susan sucked her daughter's tongue for a moment, then pulled away.

Their eyes flashed understanding to each other and Tracy turned and started out of the room. Susan's eyes watched the sensual sway of her daughter's ass, wishing she had the same courage. She wasn't sure how her son would react to his sister, but she thought that he would be delighted.

Tracy entered her brother's room without knocking. He sat on his bed, legs crossed, reading a book on history. He looked up as she walked in, smiling to see her. Tracy sat on the edge of his bed, glancing at his lap. He was already in his pajamas, but she couldn't see his cock. She caressed his smooth, face with a warm hand.

"You saw me, didn't you?" she said softly. "You saw me come out of the bathroom. I caught you looking at me, and it excited you, didn't it, Bill?"

He started to blush.

"No, don't blush, honey," she soothed. "It's all right for you to look at me. Maybe I wanted you to see me that way. Maybe I like it when you look at me."

"You do, Tracy?" he asked, his eyes shining. "You don't mind if I look at you?"

"I like it," she said again. "It makes me feel good when you look at me. I get all tingly and warm and wet."

"Wet?"

"You know, down there," she whispered, pointing between her legs.
