Brenda stood up, her legs weak. She smoothed her dress down, then realized her parities needed adjustment. She lifted her skirt again and placed her panty crotch over her cunt. She looked at herself in the mirror, pleased with the slight bulge her cunt made in her tight, nylon panties. She could see the outline of her dark pussy hair through them.

She heard the front door open and close and quickly smoothed her skirt down. She thrust her shoulders back, watching the way her tits strained out, her nipples making twin points against the white fabric. She listened to her son move through the house, knowing what he was going to do because she had listened many times before. She waited, hardly breathing, until she heard the door of the hall bathroom close. She listened closely but didn't hear the lock snap. She grinned to herself. That meant Joey was in a particular hurry today. He must have seen something at school that excited him tremendously.

Not wanting to wait too long in case her son was overly excited and jerked off fast, she slipped into the hall and tiptoed to the bathroom door. She heard her son breathing hard behind it, and her cunt responded with a hot twitch. Not sure of his reaction, Brenda found it impossible not to put her fantasy into action. She turned the knob silently and carefully, knowing he would be absorbed in the pictures of his magazines. She opened the door a crack and peeked in.

Joey was sitting on the toilet, a magazine spread out on the floor at his feet. He had his cock in his fist, and was pounding on it wildly, gasping as he stared at the pictures.

Brenda shoved the door open and stepped into the bathroom.

"Mother!" Joey yelped, trying to shove his cock between his thighs and kick the magazine shut at the same time.

"Oh, don't stop!" Brenda gurgled, her eyes bright. "Please, Joey, don't stop."

"But… but"

"Oh, hush!" she said, her eyes blazing with heat as she stood next to him. "I know you've been doing this for weeks."
