As Jimmy's fist flew up and down on his cockstalk, his head was turning from side to side as if connected by some internal clockwork, as if the root of his long hard-on ran right up his spine. His eyes were half open as his face swung towards the doorway, and then they snapped open wide, in shock, as he found himself staring directly at his mother and saw that she was staring right back at him.

Virginia, drawn to her son's cock as if to a magnet, crawled right into the open doorway and was kneeling there, one hand up under her negligee and frigging frantically away on her overheated, sodden pussy.

Jimmy blushed in mortification. He willed his fist to stop moving but, already into the steady rhythm, that fist continued to fly up and down on his fucker for a moment, keeping to the habitual pounding action. Then it slowed and ground to a halt on the hilt of his prick.

Realizing that by gripping the root, he was leaving most of his rock-hard prick exposed, he groaned and drew his hand back up to the cock-knob. He was trying to conceal his disgrace behind both hands, but his cock was far too huge to be successfully hidden. His bloated balls loomed out around one palm and his cockstalk jutted from the other.

He stared at her in horror for an instant, and then it dawned on the boy that there was no sign whatsoever of shock or anger in his mother's expression. Far from it, she was radiant with fascination.

Jimmy frowned in confusion as the details of her position slowly registered on his vision. His mother had a hand up under her nightie and he could see it moving in her crotch, and her other hand was plucking at the plump tips of her tits, and she was licking her lips!

Virginia had blushed slightly, too, when she saw that Jimmy was aware of her presence. Her hand, like his, continued to frig automatically. Her imagination leaped, seeking some possible excuse, wondering if she should say something, but what was there to say? Maybe she should crawl back out of the room and pretend it had never happened.
