She paced the room for a while, her mind spinning, erotic images whirling about in her brain. Her cunt throbbed and tingled sweetly, her tits felt swollen, nipples throbbing. What she had seen Keith do, the feel of his hard cock against her foot, their conversation, had Donna in a high state of excitement.

She turned and faced her son. "Would it be our secret?"

Tommy understood her immediately. "Yes, Mom."

Donna breathed heavily, her tits lifting and falling, nipples straining at the fabric, eyes hot.

"With or without?"

"With or without what, Mom?"

"Panties," she whispered. The cheeks of her tight ass bunched as a quiver swept through her cunt.

"Panties?" Tommy asked.

"What you said," Donna replied, barely whispering now. "You know, sit in your face, Tommy."

"You will! You'll do it, Mom!"

Donna nodded, her hands clutching her trembling stomach. She knew she was taking a step from which there would be no return.

"With or without my panties?"

Tommy squirmed on the couch, and she saw his cock pushing at his shorts again. She stared, but the head of his prick didn't come out. Her palms itched, and she licked her full lips nervously.

He was looking at her with very hot eyes, almost glazed. His young body shook, and his hands were balled into fists at his sides. Donna drew her eyes back to his face, and they stared at each other.

"What did I taste like?" she whispered. "My bike seat… what did it taste like, Tommy?"

Tommy made a gurgling sound. "Wet. Very wet."

"Have you done that before… licked a girl's bicycle seat?"

Tommy shook his head. "I didn't even think about it until I saw Judy's father do it, Mom."

Donna's cunt was on fire. She felt her pussy lips turn puffy, felt the slippery juices seep out.
