She would suck his cock and balls, spending long minutes with them in her mouth. Paul loved it. And he was learning how to lick her cunt the way she liked best. She was delighted to learn that her son loved the taste of her cunt, and she enjoyed it when he would thrust his tongue as deep into her pussy as he could, fucking it in and out.

Donna didn't really have to increase her son's sexual interest; he was already intensely interested. They did not hold back anything from on another, and when her son began using words like cunt and cock and fuck, it pleased her to no end. She enjoyed hearing him use the words. He was so young and innocent looking that it increased her passion. She used the words freely with him, too.

Often he would wake, her son up in the morning by sucking on his cock, and, a few times when he woke up before her, he would suck her tits and finger fuck her until she was wide eyed and having one orgasm after another.

Doors were never closed around her house, and it became common for them to use the bathroom to shower or piss or whatever with the door open. They would watch each other, soaping each other and toweling each other's body to glowing excitement. Usually a shower or bath would end with her sucking on his cock or Paul licking her cunt.

It was then, that summer, when Donna started going out into public without anything on under her clothing. It had started with a joke by Paul, and she found she enjoyed it.

They had taken drives out into the countryside, where they would find some isolated area. Then Donna would sit and lean against a tree, her knees up so he could lie in front of her and gaze at her hairy cunt. After he began to squirm and press his cock into the grass, he would roll over and expose his cock to his mother, who would then lean over him and suck his cock for a long time.
