"They're not very nice, are they?" Shellie said, sipping her iced tea.

Jay had seen the girl flash her cute ass, but now he was looking at his mother again, his eyes widening slightly as he saw one of her tits. He saw the light-brown nipple, and made a noisy, gulping sound.

Shellie glanced down at herself, then laughed softly. It was okay if her son saw her tit, she felt. Even though she was his mother, her tits were no different from those of any other woman, although firmer and much prettier. She wiggled her hips into a more comfortable position. Her long clit had begun to throb and swell, and it pushed at the pad beneath her.

Jay watched his mother's ass wiggling, and again he made a swallowing sound. He had caught a glimpse of his mother's crotch.

Shellie knew what he was seeing, but she didn't close her thighs. With her unusually long clit swelling into hardness, she found herself becoming excited, her cunt turning wet. With very gentle, almost subtle, movements, she squirmed her crotch at the mat, knowing her son was watching.

Jay was, indeed, watching. He saw the cheeks of his mother's swelling ass clench in tightness, saw the way she pressed her crotch at the mat. His cock began to throb, and he made no effort to conceal it. Shellie, with her eyes slitted again, peeked at him, watching his cock press at his wide-legged swim trunks. She found herself growing warmer with desire, and her hips seemed to move of their own accord.

Suddenly Jay turned away and entered the cabin.

Shellie was disappointed in him. She knew she had been teasing her son sexually, making his cock hard, doing things to draw his eye. She considered her actions, and discovered she wasn't in the least ashamed of it. Her son was interested in girls, and she was girl, although his mother. She closed her eyes and found herself wondering about Jay's cock, his balls, his young ass. That he was a virgin, she knew. He was far too young to have become close enough to a girl to fuck her, she was sure. She began to see her son in her mind, without his trunks on, his cock and balls exposed to her. She started writhing her ass, pressing her swollen clit at the mat, her cunt bubbling with sweet, wet heat.
