She wasn't sure why she was, only that what she had done with him was crazy. Johnny was her son, not her lover. Still, she would stare at his back, and feel her cunt become moist and tingling, her nipples stiff. The feel of his cock seemed to stay in her hand, and the way he had pushed his finger into her cunt… she had almost come again just thinking about it.

Jennifer was angry with herself. She knew Johnny wanted more, even if only to watch her fingerfuck her cunt while he jacked off. Mutual masturbation could be a fun thing, she knew, but Johnny was her son. He was jacking off alone in his room, and at night Jennifer would finger-fuck herself to orgasm after orgasm, envisioning his young cock and balls.

After a time, she decided that what they had done was not wrong, could not be wrong. There had been so much pleasure in it, for both of them. How could pleasure be wrong? Who were they harming? Who could ever know?

No, she decided, it was not right to have her son suffer, be frustrated.

With her mind made up, Jennifer decided she would still show herself off for him in public, and in that way give him some gratification, and satisfy her own desires to expose herself.

Jennifer had decided to take her son to the post office to check her mail. But that was not her real purpose. She would flash herself in the post office, for her son, and if anyone else was there, give them a nice peek, too.

She searched her closet and found a short skirt, a miniskirt that was coming back into fashion. She then selected a pair of very skimpy bikini panties, hardly two pieces of lacy cloth with elastic to hold them on her hips. They were flimsy, and almost transparent. The pale-blue color matched the blue of her skirt and her powder-blue lightweight sweater.
