It was the most beautiful sight Sharon had ever seen.
Bobby stared at his mother, then lowered his eyes to her knees meaningfully. Sharon knew what he wanted, but couldn't do it. She squeezed her inner thighs hard against her swollen cunt, her eyes burning on the head of his cock. Bobby slipped his shoes off, and began to work his mother's skirt up past her thigh with his toes. He was turned toward her in the same position as before. Sharon didn't protest as he pulled her skirt in to her hip with his toes. She glanced down, and saw the crotch of her panties. Now he could seethe edge of his mother's panties.
He grinned at her, a very lewd grin, his fist working on his cock. Sharon allowed her son to hold her skirt up past her hip, letting him gaze at her crotch, his fist moving. She felt as before, mesmerized by the sight of his swollen cock. Her cunt throbbed with wet heat, her clit again pressing at the nylon fabric. Her ass began to move slightly, writhing on the cushions of the couch, a soft moan bubbling from her constricted throat.
Bobby turned loose of his cock and stretched his hand toward her.
Sharon's breath caught in her throat when he cupped her knee, pulling at it. She felt weak, unable to protest, her eyes staring at his upstanding cock. When her son pulled her knee from the other, she trembled, wondering if he was going to feel her up. If that was his intention, Sharon knew she would be unable to stop him. She knew she didn't want to stop him.
But Bobby pulled at her knee, parting her legs. He leaned forward and saw the crotch of his mother's panties. He stared at her panties a long moment, his cock jerking back and forth. Sharon blushed with embarrassment, but now with shame. Then he looked up at her face. She saw the wild heat in his young eyes, felt his hand still on her knee.
