Lisa moaned and whimpered as her passion flared. She was squirming her ass, thrusting her hips as if she were fucking.

Johnny began to squirm, his breath hot, panting. He stared at his mother, then he moved his hands behind his ass, placing them over her hands.

Lisa, feeling his cock throb with more power, sucked fast, bobbing back and forth. She made wet sounds with her mouth.

Johnny did not cry out a warning.

She felt the boiling gush of come juice on her tongue. With a husky squeal, Lisa began to gulp at his spewing cock. His come juice burned into her throat, and she swallowed eagerly. He came hard, filling her mouth before she could swallow. As he came, Lisa let out a strained cry, and her cunt convulsed with the most beautiful orgasm of all.

She came hotly as her son spurted in and over into her mouth and down her throat. Even when he finished gushing, she clung to his cock with her mouth, moaning over and over, gripping his ass tightly.

Finally, she pulled back, sitting on her heels. Her face was flushed.

"My God! What did I do?" she gasped.

"You sucked my cock off, Mom," Johnny said, giggling in a bashful manner.

Lisa looked up at him now. "I sucked your… Johnny, you must think I'm terrible!"

"Mom, I think you're wonderful!"

"How can you, after that?" she asked softly. "Let me dress, now, Johnny."

Lisa was surprised that her son was not bashful about what had happened. She was equally surprised at what he had said to her.

But she was surprised most of all by her own actions.

Not that she had sucked a cock off – she had sucked off her husband many times. But this was Johnny, her son! Never before had she thought of Johnny as a sexual being.

She searched herself to find some measure of disgust. She found only desire, desire to do it again. She kept tasting Johnny's cock in her mouth, kept, seeing it so hard before her face, remembering how sweet her own orgasm had been.
