Bob lifted from his mother, his face smeared with the juices of her cunt. His eyes were bright and shining, a huge grin on his young face. He stood there, grinning down at her.

"Well, what do you think?" she asked, licking at her puffy lips.

"I think I want to suck Pamie's cunt now," he said unhesitatingly. "I wonder if her cunt tastes as good, Mom."

"The only way to find out is to suck it, I'd say," Susan laughed, swinging her legs over the edge of the lounge. "Look at your face. You've got cunt juice all over it."

Bob licked his lips. "Mmmm, sweet cunt juice, too."

He stepped into the hot tub.

Susan stood up. "Mind if I join you?"

"Come ahead."

Susan unbuttoned her dress, letting it slip from her body. She unhooked her bra, and stroked the red marks it left on her tits. Bob watched, his eyes starting to gleam again. Susan started rolling her panties down, wiggling her ass sexily and smiling at her son.

"Are you going to get in here naked Mom?"

"Do you mind?" she teased, stepping out of her panties.

"Not me," he laughed happily, "but I can't promise nothing if you do."

"You let me worry about that," she grinned, stepping to the edge of the tub. She stood with her legs parted, letting her son look up between them at her cunt. "If you've seen enough, I'm getting in."

CHAPTER FOUR

The day passed quicker than Susan realized.

The sun was turning toward the west, and she was leaning over the deck of the hot tub, her legs in the water, her tits smashed flat on the hard deck. But she didn't feel the hardness.

Her hands were stretched above her head, clawing into fists, her lips parted as she gasped in pleasure. Standing on the bench under the swirling water, Bob was fucking his cock furiously into her cunt. It was the second time he had fucked her since she had gotten in the tub. She was amazed, delightfully so, that he could achieve a hard-on almost on demand.
