Liz turned back from the refrigerator where she had started to go for the martini. It seemed to her they were being much too loud. She was irritated, and she felt her irritation turn to anger. She could even hear the springs of the couch creak as their bodies must have been shifting one on top of the other. And what was he doing to her that she should make such a half-hearted protest?

"Oh, not again, ooohhhhhh. You're tickling me," Natalie's voice cried out, deep panting groans accompanying her low guttural cries of pleasure. "Don't be so anxious, lover. Oh, no! Not again!"

Liz stopped at the doorway and looked in quietly. She could see Natalie seated on Kevin's lap, and in the poor lighting, it looked as though the girl's jersey had been pulled partially up and her shorts pulled partially down. Yes, there was no doubt about the fact that two white melon-shaped mounds of her titties were exposed, and she could see her son's hands running across them, his fingers circling the wide pink areolas and the stiffly pointed nipples. She pulled away from the door and they were still. Probably they had seen her and would stop this disgusting exhibition that belonged in a bedroom and perhaps not even there!

"Ooohhhhhh, God, Kevin," the low groan of pleasure coming from a soft feminine voice continued louder than ever, interrupted by another rash squeaking of couch springs. Then the girl broke out into a peal of teasing laughter that sent shivers of repulsion at their brazen actions through Liz. Strangely enough, quivers of sympathetic pleasure were racing through Liz's abdomen and into the soft-downed vee of her cuntal area. She thought for a moment about how Natalie had spoken of the way she satisfied herself when she got into a state similar to the one Liz was in now. But her confused anger at the young couple for making such a demonstration of themselves squelched any desire to indulge herself in such a way. Her guilt would be too great. God, even now she felt ashamed of herself for getting excited over the young couple's love play. After all, this was her own son! Why should she care?
