"Don't do it, Robbie," Karen whispered. "Not in your pants."

Naked, she moved toward him, her hips swaying. Robbie was mesmerized by his naked mother. His lips were parted and he breathed heavily. Karen stood at his side, and began to work on his pants. She opened his fly while he sat there trembling. She ran her hand into her son's pants, and pulled his cock out.

"Oh, look at it!" she gasped. "It's so hard, Robbie!"

He lay back in the lounge chair, his cock out of his pants, standing up with jerking hardness. Karen thought he looked even more desirable this way than he had on his bed with his pants at his ankles.

She stood and looked at him, spreading her feet and pushing her hips forward, her fingers framing her pussy. She spread the silky hair of her cunt, showing the wet, pink slit to her son's hungry eyes, then she opened her cunt with her fingers, her clit pushing forward in throbbing hardness.

"Feel me, baby," she whispered. "Feel mother up!"

Robbie couldn't move. He stared at her open cunt, shaking but unable to move his hand toward her.

Karen picked up his hand.

"Feel me!" she hissed hotly, curling his fingers about her cunt. "Feel mother's pussy, baby!" With her hand on top of his between her thighs, she twisted her hips, "Oooooh, can you feel how hot and wet mother's pussy is, Robbie?"

All he could do was make a noisy swallowing sound as he look at and felt her cunt. His balls seemed swollen inside his pants, aching with a dull throb, so full he could hardly stand it. When his mother pulled her hand off his, he rubbed at her cunt of his own volition, feeling her juices dripping into his palm. Karen, panting with excitement, gripped his cock and pumped it, making her son groan. She let out a soft squeal when she felt her son slip a finger into her cunt, and she bent her knees, half crouching.

The stabbing friction of her son's finger sent her ass into a shivering dance, her fist pumping almost furiously on his throbbing cock.
