She was slowly rubbing her clit when she realized she was not alone in the restroom.

Cupping her hands over her cunt, she opened her eyes. Then she heard the soft sounds coming from the stall next to hers. Her first instinct was to pull her panties up and flee, but realizing that would be foolish, she began to rub at her aunt again. She could not be seen.

"Oooooh, Mom!"

Lisa jerked.

"Shhhh! Let Mommy make it better, honey."

Lisa strained to hear, wondering what this was all about. She looked around, and noticed a small hole cut into the wall between the stalls. Feeling like a sneak, she leaned over and pressed her eye to the hole.

She saw a woman's face, a quite pretty woman about her own age. But that wasn't all she saw. She saw a hard cock jutting toward that face. She could not see anything of the man, only his cock and balls. But that was enough to tell Lisa it was not a man but a boy about Johnny's age.

Her response at seeing this was a surprise to Lisa. Her desire increased a hundred fold as she pushed her palm tightly against the hairy, soft lips of her pussy.

"Do it now, Mom," the boy said, pushing his cock to the woman's lips.

"You want it fast, don't you, darling?"

Lisa saw the woman's hand cup the boy's balls, watched her rub her lips over the smoothly swollen head of his cock. Lisa's breathing was getting hot and heavy, her hand rubbing at her cunt as she watched with blazing eyes.

Lisa gasped as she saw the woman take the boy's cock into her mouth, sucking it slowly. The woman's ovaling lips slid to the base of the boy's cock.

Running her tongue over her lips, Lisa eased her middle finger into her cunt. She felt as if her pussy was boiling between her thighs. Her cunt was so very wet now.

"Oooooh, Mom! That's so good!"

The woman moaned as she sucked back and forth on his cock.

Lisa watched. She could hear soft, wet, sucking sounds. Her cunt clamped around her buried finger, and instead of thrusting in and out, she held it deep inside, the heel of her hand smashing against her clit.
