Marty's hands slid along his mother's thighs as she squatted on the stool, preparing to slide her feet off. His hands touched the lacy panties, and Joan gave a husky laugh but said nothing. She slipped her feet from the stool, and his hands failed to move. She felt the back of her skirt catch on the stool so that when she was on her feet the dress was caught at her hips, her long, beautiful thighs exposed. She placed her hands on Marty's shoulders as he pulled his hands from her hips.

Looking down into his face, she said very softly, "You got yourself an eyeful that time, didn't you, darling?"

"Yeah!" Marty said, grinning, not at all embarrassed. "I sure did, Mom."

She kissed his cheek quickly. "You little shit," she whispered affectionately. "Peeking up mother's skirt that way."

"You didn't mind," he said.

"That's right, I didn't care," Joan laughed, the sound throaty. "I'll even let you see more."

With that, she pulled her dress to her waist and leaned against the stool.

"Look all you want, honey," she whispered in a thick voice, her eyes hot as she looked to the straining front of his pants. "Take a very good look at me."

Marty gazed down at his mother, seeing those tight panties. Suddenly, Joan cupped his cock.

"Fair is fair," she laughed, pressing against his prick. "You see me… I get to see you."

"But I haven't seen anything, Mom," he protested. "Just those silly old panties, that's all."

"I can fix that easily enough," she said. Joan hooked a thumb into the elastic waistband of her bikini panties and shoved them downward. "Now take a peek."

Marty's eyes rolled as he stared, seeing the thick curls of her pussy. Joan felt his cock jerk against her hand, and she fumbled with the zipper.

"Like I said, honey… fair is fair, so I get to see you, too…"
