Phil sighed with pleasure and did nothing to stop her. Karen whimpered as she pursed her lips in a tight circle around the blue-veined stiffness of his cock. Then she puckered her cheeks and eagerly started sucking her boy's prick, rolling her tongue all over the shiny skinned crown of his cock.

"Ahhhhh, fuck!" Unable to move the rest of his body, Phil shook his head deliriously back and forth on the pillow. "This is so fucking wrong… oh shit, it feels good. Suck it, Mom. Suck off my dick!"

Karen's pussy burned and throbbed as she fell eagerly to the task of doing just that. Up and down her head bobbed, lasciviously fucking her face with her son's magnificent hard-on. Alternately she caved in and puffed out her cheeks, working her mouth like a bellows, increasing the suctioning pressure around his cock.

Phil winced as his prick grew to painful hardness inside his mother's buttery mouth. Karen tightened her little hand around the base of his cock. Urgently she beat his meat as she sucked the prickhead, racing her fist up and down the stone-hard stiffness of his cockshaft.

"Gonna cum," Phil moaned. He managed to lift one hand and place it behind his mother's bobbing head, digging his fingers into her thick hair. "Oh God, this is the best blow job I've ever had. You suck so hard, keep sucking, Mom. Please make me cum."

Smacking, slurping sounds filled his bedroom as Karen hornily continued to give him head. The harder she sucked, the more his prick throbbed, and soon its swollen, bloated hardness told her his balls were about to explode at any moment.

"Cum for me, Son." Saliva drooled from her mouth as she took his prick momentarily from her lips, and looked at him with glistening, sex-starved eyes. "I need it, darling. I just love to drink cum! Let me keep sucking you. Shoot your big wad down my fucking throat!"

With that she dropped her head back to his lap and opened her mouth as wide as she could, cramming almost half of his big steely prick between her lips. Karen gurgled and sucked as hard as she could, feeling her cheeks flush brightly with the wanton pressure her lips and tongue made on her son's cock.
