Donny pulled away from his mother.

"What's wrong, honey?" she whispered, alarmed.

"Nothing. Mom," he said in a husky voice.

Then she saw him hooking his fingers into his wet shorts. She gasped when she shoved them down, his cock springing free. His prick stood out a good five or six inches, thick and hard. The head was swollen and she saw the silvery bubbles dripping from the piss hole.

Donny stepped out of his shorts, standing naked before his mother, proud and anxious.

Marilyn gazed with heat in her eyes at his cock. She was surprised to see thick hair at the base, and his balls appeared to be very full. Her palms itched to take his balls and cock in her hands, to stroke them, fondle them, jack on him.

"Beautiful," she whispered. "So beautiful, Donny."

"Let me see you, Mom," he groaned, "let me look at you, too."

"Oh, yes!" Marilyn squealed, unbuttoning her cotton blouse with shaking fingers.

Sliding the blouse from her shoulders, she arched her tits out. They swelled and lifted, her nipples throbbing with hardness, the pebbled discs looking swollen too. Moving her hands behind her, she located the zipper of her tight shorts. Her eyes left her son's cock.

Her shorts were very tight, and as she began to peel them down, she had to wiggle her hips. She saw her son's cock jerk up and down as he watched her shove the shorts down. Kicking them from her feet, she stood up. Her tits seemed to jiggle tightly as she watched her son's eyes move from her tits down, then stop at the triangle of dark pussy hair.

Without him saying anything she saw her son's hand come toward her. She shoved her hips out to meet him and he touched her cunt. A shiver of pleasure went through her as his other hand came up to close about one spongy tit. As he slipped his hand between her hot, velvety thighs, Marilyn's hand moved. She clutched her son's hard cock tightly, feeling the power there. She mewled with delight and began moving her fist back and forth. She pulled the head of his cock against her flesh and felt the searing moisture his piss hole left.
