She reeled with perverse pleasure as she watched her son playing with his hard cock. When he began to slide his fist back and forth, jacking off now, Lisa became weak. She had seen boys jack off when she was in school, and her husband used to jack off because he knew she enjoyed watching him.

Lisa was an unusual woman. Nothing was perverse to her, nothing degraded her, humiliated her. She loved to do anything an erotic mind could come up with.

Despite being quite satisfied with her husband, there were a few things he had refused to perform with and to her. But that didn't stop her from thinking about them, and coming all the time as she did.

Now, seeing her son jacking off as he leaned against that tree, here in the open, Lisa was very excited.

Concealed behind some thick shrubbery, she lifted her dress and began to run her hands over her inner thighs and tease her cunt with her fingertips, her eyes smoldering with passion as she watched her son's fist move back and forth on his cock.

Her cunt was going through some mild orgasms, but they were delicious orgasms. All her orgasms were delicious, mild or strong.

She could hear her son panting softly as he beat on his cock.

"Jack it off," she whispered very softly, her voice too low to carry to Mike. "Jack that beautiful cock off, darling! Let mother see that sweet, thick come juice spurt from your piss hole! Come! Mike! Come on the fucking grass! Jack off… jack off, jack off!"

Lisa cupped her pantied cunt, pressing her hot palm against the wetness of her crotch. Her other hand was squeezing at one tight ass cheek. Her hips were moving back and forth as she rubbed her steamy cunt, her eyes glassy in erotic delight.
