She sat behind the wheel as her son climbed out. She watched him trying to walk so his cock wouldn't show, and was amused. He wasn't shy, he just didn't want her, his mother, to know she had given him a hard-on, she thought.

Before he opened the door leading into the house, she opened her side of the car and started to step out and spilled her soft drink on her white skirt.

"Shit!" she said, getting out of the car, flapping her dress up and down. "I've spilled it all over my skirt."

Billy had turned when she heard her say shit, and now watched as she flapped her skirt up and down. He was seeing his mother's long legs, above her nylons, even her panties, and his cock almost came out of the leg of his jogging shorts. He wanted to stop staring, but couldn't.

Misty held her dress high, frowning, pretending she didn't know her son could see her panties.

"Now I've got to send it to the cleaners, and I just got it out."

When she lifted her eyes, she saw the head of her son's cock pushing just under the leg of his red shorts. Billy quickly turned, entering the house fast.

Misty sat back on the seat of the car, the door opened, her legs outside. She wondered about what she had done. She knew she had done it without thinking, but she had done it in front of her son. Obviously, it turned him on. His cock was so hard. The heat between her legs was tormenting her, and without pressing the button to lower the garage door, she parted her legs and began to fondle the insides of them, working her hands up to her panties, to her cunt. She looked out the lifted door at the quiet, well-kept street and the lawn across the way. She couldn't stop feeling herself, and finally she slipped her hand into her panties and began to stroke her cunt, sliding her fingers along the juicy slit, rubbing her swollen clit.
