"Mmmmmm!" she whimpered, sucking fast and hard.
Her hands slid around his hips, cupping his naked, flexing ass. She pulled him forward each time she darted her face forward. She began to squeeze his asscheeks, twisting her mouth about his cock as she sucked.
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.
There was little conversation between them until dinner.
As they ate, he told her of his day as if nothing else had happened.
Lisa listened to him, commenting now and then. But her mind was on what they had done in her bedroom.
"Johnny, what was it you said to me earlier?"
"When, Mom?"
"You know. In my bedroom, right after…" She lowered her eyes bashfully.
Johnny giggled. "Oh, you mean about sucking my cock?"
She nodded, feeling her face burn. "What about it, Mom?"
"Johnny, I… do you want to talk about it?" she asked softly.
"What's to talk about, Mom?"
"You don't think I'm horrible?"
"I told you, Mom, I think you're wonderful."
Lisa looked at him. "Johnny, tell me again what I did."
Johnny grinned wickedly. "You wanna talk dirty, Mom?"
Lisa began to tremble. "I like… I like hearing you say that. It makes me… tingle."
"Where does it tingle, Mom?" he asked, his eyes turning hot. "Down there? If you want me to talk dirty, I'll say it this way: does it make your pussy tingle, Mom?"
Lisa breathed in hotly. She nodded, her eyes moist and hot as she stared at his face. "Yes, it does."
"Mom, I don't know what got into you," Johnny said, "but I like it. I like it very much."
"You do?"
He nodded. "All the guys I know think you're the most beautiful mom in the world. I know what they wanna do with you. I punched one in the nose because he said he wished he could fuck you."
"Fuck me?" she gasped.
"Yeah. I can't let those guys say that about you. You're my mom."
Lisa had no idea that her son's friends thought of her that way. They were all so very young. What did they know about fucking?
"Johnny, I don't want you fighting," she admonished. "What they say about me doesn't matter. I don't want you fighting."
"If you say so, Mom. But what if I said I… you know, wished I could do it, too?"
"You mean, fuck me?" Lisa's words were barely a whisper.
"You like to talk dirty, Mom?"
"Answer me, Johnny." Johnny lowered his eyes to his mother's tits.
Lisa lifted her shoulders, pushing her tits outward.
"Yes, Mom," he said, his voice lowering thickly.
"Oh, Johnny!" Lisa exclaimed, her fingers clenching. "Oh, baby."
