Susan drew back, turning his cock loose and licking at his young balls, feeling his cock throb along the side of her face. Again she pulled his cock into her mouth, digging her fingers into his ass tightly, lifting her cunt up to his rubbing band.

"I might come, Mom," he said in a hoarse voice.

"Mmmmm," she replied, sucking hard.

"Want me to take it out when I come?"

"Mmmm!" she shook her head, still sucking at the thick cock.

"In your mouth?" he asked, surprised. "You want me to come in your mouth, Mom?"

"Mmmm." She nodded, her eyes bright.

"Wow!" Bob gurgled, watching her lips grip and slide on his cock.

Susan's mind spun with erotic pleasure. She sucked hard and tight on her son's cock, lifting her hips, spreading her thighs wide, making a tight circle, then churning up and down as if she were being fucked. It felt so good to let herself go, to allow her emotions to flow. It was delicious to have a hard, hot cock in her mouth after a year. Her cunt was bubbling, very wet. The crotch of her panties, pulled into her slit, were soaked.

Bob suddenly leaned down, his cock almost coming out of her mouth. Susan purred like a kitten when her son pressed his face between her legs, kissing at her panties.

She pulled his cock out of her mouth.

"Wait, baby," she gasped. "Just a minute." She adjusted the lounge chair until she was flat on her back. "Now, climb on… and stick your cock back in my mouth."

Bob spread his legs over her face, his cock aimed down into her face. For a minute she almost asked him to take the trunks off, but thought it was quite sexy this way. As she opened her mouth and took his cock in again, she wrapped her arias around him, clutching at the cheeks of his ass. She pulled him tightly into her face, his balls resting on her nose, her throat filled by hard cock. She sucked hard, then pushed him up again.
