"Jesus!" Billy cried. He propped himself up against the headboard so he could watch his mother suck on his prick.

When she had covered his cock knob with her wet kisses, she began to suck his slick cock into her mouth. Her puckered lips went down, down, the smooth cockmeat until her mouth was filled with it.

Billy squirmed on the bed in an agony of arousal. Grabbing onto the sheets, he crushed the material between his fingers.

Sally took a deep breath, and arching her neck, she sucked his prick head down into her throat and took the rest of his cock between her lips. Now his ball sac was pressed up against her chin, and she could smell the wonderful yeasty aroma of it.

"Mom!" Billy cried, his body shaking violently.

Sally was really excited now. There was nothing quite like the feel of her baby's cock rammed into her mouth and throat. She lapped at his prickshaft with her tongue while she kept up the suction with her throat and lips.

Then, just when she thought the boy couldn't take it any longer, she eased up on him, reining her throat muscles, softening her lips.

Billy groaned in disappointment. But Sally eased back, letting his cock knob pop out of her mouth. Now she began to polish his prick with licks and kisses until she had him rolling on the bed, gasping with pleasure. He humped up at her, fucking his cock back and forth through her fist, as if it were the entrance to her remarkable pussy.

Sally took her time. She explored every crease and curve in Billy's prick with her tongue, discovering the location of the most sensitive spots on the long smooth cockrod.

When she hit a real hot spot, she would stop in mid-kiss, raise her head and ask: "Do you like that, baby? Is Mommy doing you right?"

If Billy groaned and bucked up at her in response, she would lick and kiss and nibble that much harder. After nearly five minutes of this, she plunged back down on his prick again, taking the whole prickshaft in with one gulp. The cock knob bottomed out past her tonsils, and the hairy root was nestled against her lips.
