She giggled and sat up. "How do you know I'm the best?" she asked, cupping his cock and balls lovingly, fondling tenderly. "Just how many girls have you been sticking this sweet cock into?"
Bob hesitated, not knowing if he should answer.
But Susan pulled at his wet cock, a low, husky laugh coming from her, giving him the answer.
"Is your sister the only one?"
A flush came over his face as he nodded. Again Susan laughed. "Don't be ashamed of fucking Pamie," she whispered, rubbing the head of his cock around her tits, poking her nipples at his piss hole. "And don't be ashamed of fucking me."
Bob's face lit up. "It's okay, Mom?"
"Okay, my ass," she said, pulling, stretching his cock. "I think it's great!"
CHAPTER THREE
Susan found it odd that the evening passed without mention of the day.
Things seemed no different during the evening than they had always been. Pamie watched television, her brothers reading. The only one who seemed excited was Susan. Surely Bob had told Billy and Pamie.
Yet there was no indication from any of them. Susan bathed and climbed into her bed, still wondering.
Bob and Billy had been fucking their sister for a couple of weeks, Bob had told her. But surely they must have been doing a little feeling before that. It could have been going on for a very long time, she decided.
Bob, the oldest, seemed the most shy. Pamie, in the middle, had never so much as hinted she had an erotic side to her bubbling, friendly personality. Billy, the youngest, was much more bolder than his older brother. She wondered who had initiated this fucking, then realized it didn't matter. What did matter was they were fucking, making Susan's wild, erotic imaginings come true.
All three were one year apart in ages, all three still in school. Bob would graduate someday, though, and be going off to college. That would leave her with Billy and Pamie, then Pamie would go oft and finally Billy. She would be alone then. Susan didn't want to think about that.
