She raised her knee, her foot on the bed, the other leg trailing to the floor. Then she drew her negligee up above her hips, parting her thighs.

Jimmy stared at her cunt.

"Look at Mommy," she purred. "Look at Mommy's creamy cunt, darling – see how juicy I am?"

Her cunt was wide open and cuntjuice and cum came pouring from her fuckhole like a fountain.

Jimmy's hand began to creep down his belly, fingers twitching, reaching for his cock in a dreamlike unreality, as if he were hypnotized or walking in his sleep.

"Ahhhh – yeah! Toss yourself off, darling," Diana sighed. "Show Mommy how you jerk off and and I'll let you shoot all over my big tits!"

She dipped a hand into her groin, strumming her fingers against her cunt.

Jimmy's hand slid onto the hilt of his cock and his fist closed around the thick prick. He gave himself a slow push-pull. His prick leaped up like a missile from his hand, seeming to drag his loins behind in its wake.

Hauled up by his hard-on, the athletic young man heaved up from his prone position and knelt on the bed, eyes wild, lips frothy and panting, fist gripping tightly to the root of his rampaging cock.

He was kneeling over his reclining mother. Diana rested on her left hip and elbow, supporting her face in her left hand, gazing at his groin in fascination. Her thighs were parted, her belly thrust out. The woman always got turned on by looking at a cock and balls, but staring at the forbidden fruit of her own teenaged son's massive sex tackle was driving her wild.

Jimmy wasn't stroking, just holding steady at the pulsing base, his cock jutting from his fist like some meaty war club poised to strike.

His fat cock-knob was glowing like a lightbulb and pre-cum was oozing steadily from his pisshole. The thick, white goo clung to his purple slab like whipped cream on a plum.

"Oooooh – frig it, darling! Toss off onto my belly and tits!" his mother urged.
