"Who says I'm a lady?" she said, rubbing her hands over her tits. "I happen to think I'm one horny little girl. And I wouldn't be horny now if you hadn't stopped Keith and me tonight. In fact, I would have had my first big dick."

"God forgive you." Brad said, his eyes bulging. "Let's… let's get on our knees… right now and beg him to…"

"I'm going to get on my knees all right," she said, getting off the bed, "but I'm not going to do any praying." She slipped her blouse off, then dropped her skirt, now standing before him in nothing but her panties. "I'm going to get on my knees… right between your legs and suck you, big brother. I'll bet you haven't been sucked in so long your big dick is just begging for it."

Brad was so stunned by her actions he felt frozen to the chair. The only thing that moved was his jaw as it slowly dropped to his chest, and his cock, which throbbed painfully upward, lodging under the waistband of his trousers.

"Amy… you… don't know what… you're doing," he said, feeling the room spin, grow even hotter. He closed his eyes and whispered, "Get thee behind me, Satan!"

"Mmmmmmm, I'll just bet your big dick tastes so good," his sister said softly, kneeling between his legs.

Brad knew there would be temptation – Libby had told him that often enough – but he never expected it to be like this! To refuse some old whore in a bar would have been more like it. To walk away virtuously, his Bible clutched to his chest, assuming he would be in the bar in the first place, which he wouldn't.

His sister was another thing, however. She was young, ripe, and seemed to be drenched with sexual appeal. He could almost feel the way those little tits of hers would feel against his chest, almost taste the steam from that sweet pussy.

"Get thee behind me, Satan!" he murmured again, feeling his fingers on his zipper.
