Bobby looked up at his mother's face. He saw how pink it was, but he saw, too, the smoldering expression in her blue eyes. Sharon tried to hold his gaze, but couldn't. She lowered her eyes, licking her full lips. She saw how high her skirt was, and for a moment, from habit, she almost shoved it down. Her hand stopped just before she touched the hem, her foot swinging back and forth faster and faster. She felt her cunt aching with heat, her clit smashed between the wet folds. She pulled her hand back and let it drop on the couch.

Bobby caught the gesture, the hesitation, and a glow came into his eyes.

"When you're doing that, do you ever think of me?" Sharon asked, her voice very, very low, shy.

"Sometimes, Mom," Bobby admitted, his cock now straining hard inside his pants, outlined along the fly, the head of his cock inching up toward his belt.

Sharon couldn't resist peeking.

A low moan escaped her tight throat as her cunt convulsed with an orgasm. She balled her fist up near her hip, the other one on her chin pressing hard. She drew her swinging foot back, curling it about her lower leg, the pressure of her thigh hot against her contracting cunt. The blush on her face became fiery, and she felt very shy, knowing her son could tell she was coming.

Bobby gazed at his mother with interest. He saw her thigh muscles tighten below her skirt, the shudder of her shoulders.

The orgasm had been a bit stronger than the first one, but still not enough. She felt embarrassed because her son knew she came, but that fact also seemed to excite her.

"Did you come, Mom?" Bobby asked bluntly, his eyes sparkling with heat.

For a moment Sharon couldn't reply. Then, in one quick jerk of her head, she let him know she had. She couldn't turn to look at him, though. She stared down at her revealed knee, wishing she wasn't blushing so fiercely.

"Really?" Bobby asked, his voice showing his excitement. "You really came?"
