"Mom, Mom, Mom!" she heard her son gurgling.

But his voice sounded strange, as if he were calling to her from a great distance. The tone of his voice told her of his excitement, and she sucked all the more furiously on his cock. She detected an increase in the throbbing of his prick, stretching her lips wider and tighter. The head of his prick brushed at her throat every time she dived down over the cockshaft, sending tremors of ecstasy through her.

The burst of cum juice spurting into her mouth came as a surprise. Mary's eyes popped wide, the head of her son's cock still gripped tightly between her lips. She felt the cum juice, thick and hot, scalding over her tongue. Without thinking, she began to swallow.

There was a delicious taste in her mouth. It seemed as if her son's cock was gushing gallons of cum juice into her mouth. She felt the throbbing of his cock with each squirt, and her cunt blazed like a roaring fire. Her eyes remained wide with surprise as her son continued to spew his thick cum juice down her throat. Although she was no longer sucking his cock, but holding the swollen head between her lips, her tongue was moving back and forth across his gushing piss hole.

Then, just as suddenly as he had erupted, he stopped coming. Still Mary held her son's cock between her lips. Finally, she pulled her mouth from his prick and, with a flush of embarrassment on her beautiful face, lay her cheek on the side of the bed, facing away from he son.

After some time, Mary felt and heard him get off the bed. She knew Steve was pulling his wet trunks on, and still she could not face him. She knelt there on the floor with her cheek on the bed, her body shaking. She could feel her son's eyes on her, but there was nothing she could do about it. Mary didn't want to face him, talk to him. She felt miserable because of what she had done.
