"You have? Me, too!"

Her son was excited, very excited. He didn't seem at all embarrassed about being caught looking.

Before she could stop herself, Janice said, "Do you like watching her?"

A soft groan came from her son. Shooting her eyes downward, she realized her son had his hand inside his pajamas.

She swayed toward her son, her shoulder brushing his. They stood side by side, watching, as the pretty blonde pulled the pillow beneath her naked body and started to fuck it.

"That excites you, don't it, Bobby?" she said in a very low, quivery voice.

"Yeah," her son grunted.

The urge to touch her son, put her hand on the front of his pajamas, feel his cock, was overwhelming. For a long moment she managed to resist, then she found her hand moving out. Whether Bobby knew what she was about to do or not, she didn't know. Both of them were gazing at the girl, seeing that tight, cute ass writhe and twist, heard the soft whimpers of pleasure coming across the fence.

Janice placed her palm against the front of her son's pajamas.

She heard Bobby gasp, but he didn't turn his head. She felt the roundness of his cock burning against her palm, and there was a wetness, too, but no movement. Then her son moved his hand. He's jacking off, she thought with a hot thrill. Bobby is jacking on his cock, and he can feel my palm against the head of his prick! I wonder if he would…

Janice moved her fingers, and Bobby turned loose of his cock. She closed her fingers about her son's prick through his thin pajama bottoms. She squeezed her son's cock.

Then Janice shoved her hand into his pajama bottoms, closing her hot hand around his prick. It was very, very hard, throbbing and quivering. She squeezed it hard enough to make her son gasp with delight. Then she moved her fist.

"Oh, Mom!" Bobby groaned, arching his hips forward as she slid her fist back and forth on his cock.

"Shhhhh!" she hissed. "You watch the girl… don't worry about what I'm doing. Just watch the girl with her pillow, darling."
