Karen pulled her son's hand off her head, lowering it to her naked tit, curling his fingers around it. She felt his cock swelling in her mouth and mewled with delight. Her tongue licked and when his cock was half-hard, she bobbed her face up and down, sucking with wet hunger. Gripping his thigh, she felt her son squirming. His hand dug into her firm tit, her nipple boring into his palm. She sucked hard, whimpering with ecstasy, her lips burning and tingling. Her tongue moved constantly as her mouth darted up and down his cock. The cheeks of her ass bunched when her come-filled cunt began to throb.

Robbie's other hand rested on top of her head, his eyes glazed as he watched his mother's mouth sliding up and down his cock. Karen didn't mind his hand on her head, and she had wanted him to hold her tit as she sucked him.

Robbie squeezed her tit hard, making her moan around his cock, and the hand on her head was pushing her face down. She let him push her, writhing her lips around the base of his prick. His cock did not go as deep into her mouth as his father's did, but it was wonderful just the same. His cock was so hot, so hard, in her mouth that she wanted to gobble it for hours. Her cunt was twitching, his come juice running along her inner thighs, and she rubbed them together, her face moving up and down his cock with quicker strokes.

She felt her son pushing upward, running his cock into her mouth as she came down. With her eyes closed, she fucked her son's cock with her mouth, shivering and trembling with ecstasy.

She twisted her lips around and around, glancing at his happy face now and then, her eyes shining encouragement at him. She made wet, sucking sounds, letting her son know how much she loved sucking an his cock.

"Mom, you're going to… ahhh, Mom!" Robbie, she knew, wanted to pull his cock out of her mouth because he was about to come. He didn't know she wanted it, wanted to taste his sweet, hot come juice gush down her throat. But even if he wanted to jerk his cock out, the urge to push deeper was the stronger of the urges.
